Detailed Description

In order that the present invention may be more clearly understood, the following detailed description is given with reference to the accompanying drawings.

In order to explain the specific function and the use scene of the structure more clearly, the embodiment takes lamp parts as an example, three parts of the lamp need to be assembled and connected, and the traditional mode has the defects of large occupied space, inconvenient operation, insufficient pretightening force and the like.

Therefore, as shown in fig. 1-8, in the present embodiment, a screw locking structure with a pre-assembly function is provided, which mainly comprises a screw seat 1, a fastener 3, a pressing plate 2, a screw 4, and the like, wherein the screw seat 1, the fastener 3, and the pressing plate 2 are sequentially arranged during assembly, that is, the fastener 3 is in a middle position, the screw seat 1 and the pressing plate 2 are separately arranged on two end surface sides of the fastener 3, and the screw 4 passes through the pressing plate 2 side to fasten the three. Of course, the three structures of the screw seat 1, the engaging member 3 and the pressing plate 2 can be formed by integrally forming three lamp parts when being arranged, and can also be connected to specific positions of the three lamp parts by welding and other fixing modes, and finally the three structures of the screw seat 1, the engaging member 3 and the pressing plate 2 are stably connected by the locking action of the screw 4, so that the three lamp parts are assembled together.

Concrete this embodiment is when designing, screw seat 1 is mutually perpendicular with fastener 3, can be earlier in the time of pre-assembling in order to accomplish the location with 3 block of fastener from the side with screw seat 1, this point is different from the pre-assembling mode of traditional bolt, the direction that makes pre-assembling is perpendicular with 4 lock attaches directions of screw, so save a large amount of bolts promptly, the shared inside operating space of buckle, make the time of pre-assembling can directly hug closely the lamps and lanterns part and operate, not only convenient but also do not account for inner space, and is swift laborsaving. Meanwhile, a limiting step 101 is formed at one end of the screw seat 1 close to the clamping piece 3, the limiting step 101 plays a role in limiting and abutting, the screw seat 1 is clamped on the clamping piece 3 from the side surface during assembly, and abutting is formed on one end surface of the clamping piece 3 through the limiting step 101; in addition, a boss 20 is formed at the center of one end of the pressure plate 2 close to the clamping piece 3, and the boss 20 is tightly abutted against the other end face of the clamping piece 3 during assembly; the center of the screw seat 1 is provided with a threaded hole 102, the center of the pressing plate 2 is provided with a round hole 200, the screw 4 penetrates through the round hole 200 and the clamping piece 3 and is in threaded connection with the threaded hole 102, and the screw 4 is screwed until the abutting end of the screw 4 presses the outer end face of the pressing plate 2, so that the screw seat 1, the clamping piece 3 and the pressing plate 2 can be fastened and locked. Above-mentioned design has not only simplified the assembly process greatly, can also promote the fastness of part assembly, and the design of boss can avoid normal part to provide the problem that the pretightning force is not enough, easily drops when holding by a large scale for locking ability after the screw lock attaches is stronger, more stable, and three lamps and lanterns part assembly effect is better, does benefit to life's extension.

Specifically, the engaging member 3 in this embodiment is an elastic body 30, specifically a circuit board made of FR4 material, that is, the elastic body 30 and the middle lamp part are integrally formed. In order to achieve the effect of elastic clamping, a bayonet 301 is disposed on one side of the elastic body 30, two arc-shaped through holes 302 are disposed at positions of the elastic body 30 close to the bayonet 301, and when assembling, the screw seat 1 is clamped into the bayonet 301 of the elastic body 30 from a side surface and forms a butting against one end surface of the elastic body 30 through the limiting step 101. Adopt above-mentioned elastic body 30 and set up bayonet socket 301 and arc perforation 302 and realize the effect of block, can make during the pre-installation more swiftly convenient, still be formed with direction inclined plane 303 in the bayonet socket 301 outer edge of elastic body 30 in addition to this makes during the assembly screw base 1 can be faster, accurately block in bayonet socket 301, and then efficiency during the promotion assembly.

Of course, in other embodiments, the elastic body 30 does not necessarily need to be made of FR4 material as used in the field of lighting devices, the material of the elastic body 30 may be made of other plastics, and the same engaging effect can be achieved by the design of the bayonet 301 and the arc-shaped through hole 302.

In order to limit and guide the screw 4 when being locked, an annular limiting seat 21 is formed at one end of the pressing plate 2 far away from the clamping piece 3, and the abutting end of the screw 4 can enter the limiting seat 21 when being locked, so that the offset and dislocation of the screw 4 are prevented, and the fastening accuracy is improved.

In order to further strengthen the effect that the lock of screw 4 attaches and compress tightly, the circular slot 201 has still been seted up at the one end central authorities that the fastener 3 was kept away from to clamp plate 2, is provided with rubber circle 5 in circular slot 201, so make screw 4 more firm when the locking compresses tightly, difficult not hard up to promote the whole fastness of three lamps and lanterns part assembly.
