Description

Ceiling fan capable of quickly installing blades

The present invention relates to a fan, and more particularly to a ceiling fan capable of quickly installing blades.

As shown in FIG. 1 and FIG. 2, the ceiling fan 10 disclosed in US Pat. No. 6,171,059 has a leaf frame 11, a blade 12, a mounting unit 13, and a cover plate 14. The leaf frame 11 has a plug block 111, two slots 112 disposed on the left and right sides of the top surface of the plug block 111, and two slots disposed in the left and right direction on the plug block 111 and communicating with the two slots 112. a slot 113, the blade 12 has an opening 121 disposed at the inner end, and two latching slots 122 respectively communicating with the opening 121. The mounting unit 13 has springs 131 respectively mounted in the two receiving slots 113, and Two latching blocks 132 respectively pushed by the two springs 131 are locked and fixed on the top surface of the plugging block 111.

When assembling, the opening 121 of the blade 12 is first aligned with the plug block 111 of the blade frame 11, and then the blade 12 is pushed into the plug block 111 in a mounting direction I, when the two latching block 132 enters The two card slots 122 complete the assembly of the blade 12 with the blade frame 11.

Although the ceiling fan 10 has the characteristics that the blade 12 and the blade frame 11 can be quickly assembled, the following problems actually exist: Since the latching block 132 slidably enters and exits the latching slot 122, there must be a machining margin between the two, although the lateral clamping force of the blade 12 can be given by the two latching block 132, but There is still a centrifugal gap along the mounting direction I between the two. When the blade 12 rotates, the blade 12 is turned outward due to the centrifugal force. At this time, the centrifugal gap will cause the rotation balance of the blade 12 to be poor and easy to shake. And will produce rotational noise.

In addition, the ceiling fan disclosed in US Pat. No. pat. 686211 has a leaf frame as a one-piece structure, which can be assembled for several blades at the same time, and is inserted laterally between the blade frame and the blade by a spring pull pin to complete assembly. The ceiling fan also has a problem that the rotation balance of the blade is poor, and it is easy to shake, which causes rotational noise.

Therefore, the object of the present invention is to provide a ceiling fan capable of quickly installing a blade which can optimize the rotational balance of the blade, reduce sloshing, and reduce rotational noise.

Therefore, the novel ceiling fan capable of quickly installing the blade comprises a suspension unit, a motor, a leaf frame unit, a plurality of blades and a plurality of mounting units.

The motor is mounted to the suspension unit.

The leaf stand unit is driven by the motor and includes a plurality of leaf frame bodies, each of which has a slot.

Each of the blades includes a plug portion that can be inserted into the corresponding slot, and a free portion that is opposite to the insert portion, the plug portion having an inner portion The end surface is a pair of side surfaces extending from the inner end surface toward the free portion, and a pair of recessed grooves respectively recessed from the side surfaces.

The mounting unit is the same as the number of the leaf frame body, and each of the mounting units includes a pair of side elastic fasteners disposed on the leaf frame body and elastically abutting the card slot of the socket portion, and a mounting portion is mounted thereon The leaf holder body pushes the centrifugal pusher of the inner end surface of the insertion portion.

The utility model has the advantages that the inner end surface of the insertion portion is pushed by the centrifugal elastic pushing member, so that the blade abuts the side elastic fasteners in the centrifugal direction, so that the rotation balance of the blade can be better and reduced. Shake and reduce the noise of rotation.

The segment 672 pushes the inner end surface 511 of the insertion portion 51, so that the blade 50 has a tendency to move toward the centrifugal direction, that is, a tendency to move in the opposite direction of the mounting direction II (see FIG. 8), thereby making the The abutting surface 531 abuts against the bent portion 635, so that the blade 50 can abut the side elastic members 63 in the centrifugal direction.

As shown in FIG. 9, the movable elastic piece 633 can be conveniently pushed from the latching position to the releasing position by inserting a tool T (for example, a flat-blade screwdriver) into the dismounting hole 612 and the dismounting groove 54. Further, the blade 50 can be easily and quickly detached from the blade frame body 41 in a disassembly direction III.

In summary, the novel ceiling fan capable of quickly installing the blade has the following advantages and advantages, so that the purpose can be achieved:

1. The present invention pushes the inner end surface 511 of the insertion portion 51 by the centrifugal elastic pushing member 67, so that the blade 50 abuts the side elastic fasteners 63 in the centrifugal direction, and the rotation of the blade 50 can be generated. Balanced, reduced sloshing, reduced rotation noise and benefits.

Second, the present invention can prevent assembly errors to improve assembly efficiency by the foolproof unit 70.

3. The present invention can easily and quickly disassemble the blade 50 by the detaching hole 612 and the detaching groove 54.

However, the above is only the preferred embodiment of the present invention, and the scope of the present invention cannot be limited thereto, that is, the simple equivalent change and repair according to the scope of the patent application and the contents of the patent specification. Decorations are still covered by this new patent.
