Description

  The present invention relates to a monkey wrench in which an engagement hole for a bolt head or a nut is separately provided.

  Conventionally, a spanner provided with fitting parts that can be fitted to nuts of different sizes at both ends is known, but in a monkey wrench, one of the clamping pieces is movable and nuts of various diameters or Since it can be applied to a bolt head, no consideration is given to providing a through-hole that can be applied to two types of nuts (or bolt heads) like a spanner (usually not necessary). However, it is easy to change the distance of the monkey wrench clamping piece in the middle in order to tighten multiple bolts or nuts of different sizes in high-altitude work or places where there are restrictions on the body and movement during work Rather, it also contributed to the decline in work efficiency.

  Conventionally, a wrench with a handle that fits nuts (or bolt heads) with different diameters at both ends of the grip handle has been known. However, since it was only applicable to two types of nuts, there are multiple types of spanners. The purpose was achieved by preparing. In addition, the adjustable wrench can adjust the width of the part that fits the nut, so if you have one adjustable wrench, you will have the same effect as multiple types of spanner sets, but the normal adjustable wrench is usually used for temporary tightening, Since a spanner is used for final tightening, it was common to share a spanner with a monkey wrench.

  Therefore, it is normal to work with both a monkey wrench and a spanner (fitting part fixed). However, when the number of tools increases, there is a problem that accidents such as tool dropping are likely to occur.

  Also, when turning a thumbscrew, etc., it is almost manual. However, if the screw is fixed for some reason, it may be difficult to turn it manually. The instrument was used.

  However, this invention solves the above-mentioned conventional problems by attaching a through-hole to be fitted to turn a nut or bolt on the monkey wrench so that the monkey wrench can be used as both a wrench and a monkey wrench. It was.

  The monkey wrench transmits the rotational force by bringing the two surfaces of the fixed surface and the movable surface into contact with the corresponding two surfaces of the nut or the hexagonal portion of the bolt head. Therefore, although the nut having a facing distance of 5 mm to 35 mm can be effectively rotated, it is considered that the actual use range has the largest facing distance of 10 mm to 30 mm. Therefore, the rotation of the bolts and nuts in the above-mentioned size range can achieve the purpose sufficiently with a single monkey wrench, but the bolt (or nut) for tightening due to the characteristics of the monkey wrench. Since tightening may not be sufficient, a monkey wrench may be used for temporary tightening and a spanner may be used for final tightening.

  However, there are many cases where two or three spanners are carried in the field where it is known that two or three types of bolts or nuts are rotated due to the nature of the field. That is, in the case of the monkey wrench, not only does the size adjustment need to be performed every time the size of the nut is changed, but the monkey wrench is generally heavier than the spanner and may not be easily used. On the other hand, in the case of a spanner, the size is specified for each nut, and it is surely fitted and can be tightened as it is.

  In the case of a monkey wrench, a single monkey wrench is sufficient for various sizes of nuts. In the case of a spanner, the spanner must be changed each time the nut size changes. In the case of a monkey wrench, it must be adjusted and fitted well every time it is fitted to the nut. Even if the monkey wrench is fitted, there may be some looseness due to looseness of the monkey wrench screw. In the case of, each has its own qualities, such as being properly fitted and having no room for loosening.

  Next, in the case of a monkey wrench, for example, a nut having a size of 5 mm to 35 mm (preferably 10 mm to 30 mm) can be shared. Therefore, it is not necessary to prepare a plurality of nuts unlike a spanner. Since it is necessary to have a wrench suitable for each size, it is common to carry a plurality of wrench sets.

  Therefore, some construction or civil engineering tools are designed to perform two functions with a single tool. However, it is not necessary to consider turning a nut of a different size, only for a monkey wrench. There was no need to provide two.

  However, at a construction site where two or three types of nuts are used, it was sometimes easier to work with two or three spanners than with a single monkey wrench. There was no such consideration.

  However, this idea has developed a convenient monkey wrench that carries a monkey wrench and spanner with a single monkey wrench.

  That is, this device is a nut with a one-way movable ring that fits on a nut at the other end of a monkey wrench body that has a movable clamping piece installed on one end to fit a nut or bolt head of a different size. A monkey wrench characterized by having a hole, and fitted to the nut at the other end of the monkey wrench body with a movable clamping piece installed at one end to fit a nut or bolt head of a different size. A monkey wrench characterized by providing a nut hole with a one-way movable ring to be mounted and a through hole for rotating a wing nut in the middle part of the monkey wrench body, and having a different size at one end. A nut hole with a one-way movable ring fitted to the nut is provided at the other end of the monkey wrench main body on which the movable clamping piece is installed so as to be fitted to the nut or bolt head, and has a size different from that of the nut hole. of A monkey wrench, characterized in that it has provided adjacent the Tsu bets hole.

  Another device has a one-way movable ring fitted to the nut at the other end of the monkey wrench main body on which the movable clamping piece is installed in order to fit the nut or bolt head of a different size at one end. A monkey wrench characterized in that a nut hole is provided, a nut hole having a size different from that of the nut hole is provided next, and a through hole for rotating a wing nut is provided in an intermediate portion of the monkey wrench body, At one end, a nut hole with a one-way movable ring to be fitted to the nut is provided at the other end of the monkey wrench body on which the movable clamping piece is installed in order to be fitted to nuts or bolt heads of different sizes, A nut hole having a size different from that of the nut hole is provided next to the movable ring, and a plurality of concave and convex teeth are provided on an outer peripheral circular wall, and the circular teeth of the prepared piece are meshed with the concave and convex teeth, and the prepared piece is a monkey. One direction into the wrench body It is a monkey wrench characterized by being slidably supported so that it can only roll, in addition to a monkey wrench body that has a movable clamping piece installed at one end to fit a nut or bolt head of a different size. A nut hole with a one-way movable ring fitted to the nut is provided at the end, a nut hole having a size different from that of the nut hole is provided next to each other, and the maximum opening interval of the monkey wrench is set to 32 mm. This is a monkey wrench characterized by having a thickness of 220 mm.

  In the normal tool industry, a 30 mm opening monkey wrench has a total length of 200 mm. The 36 mm opening monkey wrench has a total length of 250 mm. Therefore, if you have a monkey wrench with a total length of 250 mm, you can handle up to 6-minute bolts (32 mm across). However, the monkey wrench having an opening of 36 mm is not only heavy with a total length of 250 mm, but also protrudes greatly from a normal waist bag, making it easy for the tool to fall, and is dangerous and inconvenient.

    In other words, in order to rotate the 6-minute bolt, a monkey wrench with an opening of 36 mm and a length of 250 mm is required, and if a special waist bag is not used to put the monkey wrench of this length, in terms of safety I have anxiety.

    Therefore, if a monkey wrench having a length of 32 mm and a length of 220 mm is newly made, it becomes relatively light and a normal waist bag can be used.

    However, according to the conventional practice, only two types of monkey wrench with an opening of 30 mm and an overall length of 200 mm and an opening of 36 mm and an overall length of 250 mm were made. Was. Therefore, according to this device, since the opening is 32 mm and the total length is 220 mm, there is an advantage that the torque is larger than that of a conventional monkey wrench having a total length of 200 mm.

  In this device, a nut hole with a one-way movable ring is provided at one end of the main body of the monkey wrench. Therefore, if the sizes match, the nut can be rotated without using the variable wrench mounting portion.

  In addition, since the through hole for inserting the wing nut is provided in the main body, the entire weight can be reduced, and even a wing nut that is difficult to rotate can be easily rotated.

  Therefore, even if the work involves bringing both a monkey wrench and a spanner in the past, if one monkey wrench is brought together, it is possible to achieve the same purpose as using a spanner together (with one monkey wrench). Temporary tightening and permanent tightening are possible).

(A) The top view of the Example of this invention, (b) Similarly front view. (A) A sectional view taken along the line AA in FIG. (A), (b) A sectional view taken along the line BB, (c) An enlarged plan view in which a part of the rotation hole is cut off, and (d) FIG. ) Middle CC sectional view, (e) Explanatory drawing which similarly shows the insertion state of a thumbscrew.

  This device is provided with a nut hole with a one-way movable ring fitted to the nut on the end side of the handle of the monkey wrench, with a predetermined interval inside the nut hole and having a smaller diameter than the nut hole. A nut hole is provided.

  In addition, two rectangular through holes (for wing nuts) having both ends semicircular at the center (thin portion) of the handle are installed in parallel. The through hole is used by inserting a wing nut as shown in FIG.

  In the above, by providing two nut holes with different diameters, it corresponds to one spanner with fitting parts with different diameters at both ends, and the grip part is longer than the spanner (because of a monkey wrench), giving rotational force Even if the force is small, it can be applied with the same tightening force as the corresponding spanner.

  An embodiment of this invention will be described with reference to FIGS. A protrusion 2 having a fixed surface 2a for clamping a nut is provided at one end 1a of the main body 1 of the monkey wrench 15, and a movable piece 3 having a movable surface 3a facing the fixed surface 2a is detachable. Install. The base tooth 3b of the movable piece 3 is meshed with the gear 4a of the operation shaft 4 installed on the base of the one end, and the operation piece 4 is rotated to indicate the movable piece 3 with arrows 5 and 6. By reciprocating like this, a large and small nut can be clamped.

  The other end 1 b of the main body 1 is provided with a nut hole 8 with a one-way rotating ring 7, and a nut hole 9 having a different hole diameter is provided adjacent to the nut hole 8. The central portion 1c of the main body 1 is formed thin, and the thin portion is provided with wing nut holes 10 and 10 each having an arc shape at both ends and a straight central portion. The wing nut hole 10 is configured such that the wing nut 17 can be fitted and locked so that the wing nut 17 can be rotated (FIG. 2).

  The main body 1 has an overall length L of 220 mm, and the maximum opening interval of the movable pieces is 32 mm, so that it is easier to apply a rotational force than a conventional monkey wrench having an opening interval of 30 mm.

  The circular teeth 11a of the adjusting piece 11 are engaged with the concave and convex teeth 7a of the rotating ring 7 of the nut hole 8, and the adjusting piece 11 is supported by a spring 12 (FIG. 2). Therefore, when the rotating ring rotates in the direction of arrow 13, the adjustment piece 11 presses the spring 12 and escapes, but when the rotation ring tries to rotate in the direction of arrow 14, the adjustment piece 11 is fixed. Therefore, the rotating ring 7 rotates only in one direction and reciprocal rotation is prevented. In the figure, 16 is a screw for stopping the spring, and 18 is a mounting hole for the safety rope (FIG. 1).

  According to the above embodiment, the large and small nut holes are set on the monkey wrench that can rotate the large and small diameter nuts. The set nut holes are fitted to the nuts with the same exact dimensions as the wrench and rotated. Can be tightened.

  If the monkey wrench is provided with nut holes of different sizes and several kinds of monkey wrench are prepared according to the size of the nut hole, various works can be performed without a spanner. That is, since the dimensions and types of nuts or bolts are determined for each construction site (usually not a wide variety), several types of dimensions are sufficient.

  In this device, two nut holes are provided, but three nut holes may be provided. Depending on the type of construction, one or two spanners and a monkey wrench may be required, but according to the monkey wrench of this device, the spanner can be made unnecessary.
