Description

Multi-purpose flashlight

The utility model belongs to portable illumination device.

Common portable illumination device, especially torch, be portable mostly, as US Patent specification US4,237,526 disclose the electric lighting device that steam vent and watertight case are arranged, but this device is to underwater operation, mountain-climbing, steering vehicle is driven inland navigation craft, countryside loading and unloading article, genuine cave operation and seabeach operation or the like all need the work of bimanualness, the work that has a strong impact on during use is carried out, if can vacate two manual works with miner's helmet-type electric light, but adopts the battery illumination heavy again, again can not underwater operation, also be unwell to the traveller and use.

The purpose of this utility model provides the portable Water-sealed electric torch of a kind of multiduty integral body, can satisfy the above-mentioned various operation instructions for uses of mentioning as the separated into two parts pocket helmet-type torch of watertight separately again.

Task of the present utility model is achieved through the following technical solutions.

The utility model basic structure is by lens (1), reflector (3), bulb (7), tube face (9), outer cover body (41), shell head cap (2), head cap back cover (5), body cap (18), dry cell (40), battery is pressed touch panel (21), lead (11,12,16,17), packer (15,22), switch (30), air bleeding valve (37) is formed.During whole the use, can be used as portable torch and use, when separated into two parts uses, can make pocket helmet-type torch and use.

Lens (1) are contained on the shell head cap (2) hermetically, and lens the inside peripheries (43) are located, and processing one circle or a few circle ring-band shape matsurface prevents the light beam spurious reflections.Shell head cap (2) is connected with outer cover body (41) with double end rectangular teeth screw thread, compresses " O " shape sealing ring (6), makes the sealing of shell head cap and outer cover body.Reflector (3) is contained on the shell head cap (2), is the parabolic type speculum.Bulb (7) is contained on the tube face (9), by reed (8,11,10) bulb is pressed on the reflector (3).Head cap back cover (5) also is connected with the shell head cap with double end rectangular teeth screw thread, compresses " O " shape sealing ring (4), and the shell head cap is partly sealed, and also compresses reed (10), and bulb is stably loaded on reflector.Switch enclosure (31), switch (30), switch rubber case (29), reed (35), air bleeding valve (37), battery pressure touch panel (21) are housed on the outer cover body (41).Body cap (18) is threaded with the double end rectangular teeth, compresses battery and presses touch panel (21), also compresses dry cell (40), guarantees that battery is stabilized in the position in the housing, also compresses " O " shape sealing ring (19) simultaneously, and outer cover body is partly sealed.Packer (22) is housed on the body cap (18), stuffing-box compresses " O " shape sealing ring (20) and guarantees the body watertight, the other end packer (15) of lead is contained on the head cap back cover (5), and stuffing-box compresses " O " shape sealing ring (14), and head cap is partly sealed.

The circuit of torch is to be contacted with reed (26) by the positive pole of dry cell (40) (27), press the interior elasticity guide card of touch panel (21) to link lead (32) by battery and enter switch (30), again by lead (33), get back to battery and press another elasticity guide card on the touch panel, guide card contacts with lead (17) on the packer (22), be connected with bulb (7) by lead reed (11), contact with the negative pole (27) of dry cell via lead (12), wiring card (13), lead (16) and reed (23) again.

Embodiment one:

Accompanying drawing three is the basic structure of Multipurpose flashlight, and the description of foregoing circuit, can be used as the whole watertight situation of Multipurpose flashlight and uses.The directional light optically focused that when implementing, adopts lens (1) to reflect through paraboloid (3) by the light of bulb (7) emission, and locate to process one at lens the inside peripheries (43) and enclose or a few circle ring-band shape matsurface, prevent the light beam spurious reflections, improve illumination distances, reflector is to use the plastics manufacturing, above the plating reflecting surface.In the outer cover body one or several dry cell can be installed, shell head cap (2) and body cap (18) respectively adopt double end rectangular teeth screw thread, and mounting or dismounting are convenient.Body cap both sides rib is for gaining in strength, the outside also play the effect of rotation impetus.It is first-class that hook on the outer cover body (39) can hang over waistband with torch.Some places ribs (38) are arranged on the body.Switch (30) is the press button of using always, with by with logical, weighs normal open on time during flicking, and is heavy more normally closed on time.Rubber case on the switch (29) is for rainproof, water, and dustproof, its end face can be pressed, other parts and switch enclosure (31) sealing gummed.Packer (15), (22) are the devices that lead is crossed watertight bulkhead, and the centre can be filled out with plasticine, neoprene, resin and other material etc., present embodiment adopts nut shape housing, and the centre is filled out with synthetic resin or rubber, represents with (25), (44) among the figure.Accompanying drawing five is packer (22) enlarged drawings, with the endless metal contact-making surface that (17b) is energising usefulness, is the energising Metal Contact face of another utmost point (16a) (17a), and (25) are fillers.Accompanying drawing six is air bleeding valve enlarged drawings, and air bleeding valve (37) is made up of valve body (37a), spring (49), valve block (47,48) and nut (50).(36) be " O " shape sealing ring, (48) are the matrixes of valve block, are that rubber is made, and (47) are that the microcellular foam (as polypropylene, polyurethane) that is bonded on the matrix is made.In outer cover body (41), because dry cell etc. produce the elastic force of the pressure of gas greater than spring (49), gas can be discharged outside the body, and when laying up usually, minimum gas also can pass through microporous layers (47) and discharge.When torch immersed in the water, along with the degree of depth increases, the pressure of water also increased, and water is pressed to valve block by the aperture of nut (50), increases watertightness, and microporous layers this moment (47) is compressed inoperative.Putting forth effort groove when (42) on the shell head cap are mounting or dismounting head cap screw thread, also is decorative pattern.Braces usefulness is worn in hole on the outer cover body (28), (34), can be with the braces back of the body piggyback during use.

Embodiment two, when needs illuminations is vacateed two craft when doing again, Multipurpose flashlight can be divided into head cap watertight portion and body watertight portion, see accompanying drawing seven, the head cap part can be made blank cap with nylon knitting belt, a braid over braid of its front passes head cap back cover (5) and goes up extension loop (45), (46) (seeing accompanying drawing four), is fixed tightly on the cap, can be worn over head when the user of service works and go up (seeing accompanying drawing two).The hook (39) of body part is hung on user of service's the waistband or waist-belt, and Push switch rubber case (29) can throw light on.Can vacate two hands like this, no matter by land, waterborne, can both carry out above-mentioned various operation under water, reach the purpose of this utility model.

When using, do not require the torch watertight, can save packer (15), (22) and air bleeding valve (37), simplified structure.
