Description

A fastening kit for injection molded plates Technical Field

[0001] This utility model relates to the field of fastener technology, specifically to a fastening kit for injection molded plates. Background Technology

[0002] In existing technologies, when bolts and nuts are tightened on injection-molded plates, washers are added between the bolts and nuts to prevent the bolt heads and nuts from directly pressing against the injection-molded plates and causing cracking or damage. However, washers are usually independent components without a direct connection to the bolts and nuts, making it easy for washers to be missed during tightening. Summary of the Invention

[0003] To address the shortcomings of the prior art, this utility model proposes a fastening kit for injection molded plates.

[0004] To achieve the above-mentioned technical effects, the present invention adopts the following solution:

[0005] A fastening kit for injection molded plates, including matching bolts and nuts;

[0006] The bolt includes a shank, a screw head, and a first washer. The screw head is fixed to one end of the shank, and the first washer is fixed to the shank and surrounds the shank. A first groove is formed between the first washer and the screw head, surrounding the shank. An external thread is provided on the shank, and the external thread is located on the side of the first washer away from the screw head.

[0007] The nut includes a connecting part, a head, and a second washer. The connecting part and the second washer are respectively fixed at both ends of the connecting part. A second slot is formed around the connecting part at intervals between the head and the second washer. A connecting hole is provided that passes through the head, the connecting part, and the second washer. The inner wall of the connecting hole is provided with an internal thread that matches the external thread.

[0008] In the preferred technical solution, both the screw head and the head are square in shape.

[0009] In a preferred embodiment, the surfaces of the bolt and nut are provided with either a chromium plating layer or a nickel plating layer.

[0010] In a preferred embodiment, the surfaces of the internal and external threads are provided with a frosted layer.

[0011] In a preferred embodiment, the first washer has a first groove surrounding the rod portion on the side facing the nut, and a first rubber ring protruding from the first washer is embedded in the first groove; the second washer has a second groove surrounding the connecting hole on the side facing the bolt, and a second rubber ring protruding from the second washer is embedded in the second groove.

[0012] Compared with existing technologies, the beneficial effects are:

[0013] This utility model has a simple structure and is easy to use. The first and second gaskets are directly fixed to the bolts and nuts, so when tightening on the injection molding plate, the bolts and nuts can be pressed directly onto the injection molding plate without causing the gaskets to be missed.

[0016] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments of the present utility model. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments.

[0017] A fastening kit for injection molded plates, including matching bolts and nuts.

[0018] The bolt includes a shank 1, a screw head 2, and a first washer 3. The screw head 2 is fixedly disposed at one end of the shank 1. The first washer 3 is fixedly disposed on the shank 1 and arranged around the shank 1. A first slot 5 is formed between the first washer 3 and the screw head 2 around the shank 1. An external thread 4 is provided on the shank 1. The external thread 4 is located on the side of the first washer 3 away from the screw head 2.

[0019] The nut includes a connecting part 6, a head 7, and a second washer 8. The connecting part 6 and the second washer 8 are respectively fixed at both ends of the connecting part 6. A second slot 11 is provided between the head 7 and the second washer 8 to form a circle around the connecting part 6. A connecting hole 9 is provided that passes through the head 7, the connecting part 6, and the second washer 8. An internal thread 10 matching the external thread 4 is provided on the inner wall of the connecting hole 9.

[0020] When fastening on the injection molding plate, the first washer 3 and the second washer 8 are directly fixed to the bolt and nut. Thus, when fastening on the injection molding plate, the bolt and nut can be pressed directly onto the injection molding plate without causing any washer to be missed.

[0021] In the preferred embodiment, both the screw head 2 and the head 7 are square in shape.

[0022] In a preferred embodiment, the surfaces of the bolts and nuts are provided with either a chromium plating layer or a nickel plating layer. The chromium or nickel plating layer can improve the surface corrosion resistance of the bolts and nuts and also increase their strength to a certain extent.

[0023] In a preferred embodiment, the surfaces of the internal thread 10 and the external thread 4 are provided with a frosted layer. After the bolt and nut are tightened, the frosted layer enhances the friction between the external thread 4 and the internal thread 10, thereby preventing loosening.

[0024] In a preferred embodiment, the first washer 3 has a first groove surrounding the rod portion 1 on the side facing the nut, and a first rubber ring protruding from the first washer 3 is embedded in the first groove; the second washer 8 has a second groove surrounding the connecting hole 9 on the side facing the bolt, and a second rubber ring protruding from the second washer 8 is embedded in the second groove. The first and second rubber rings protrude by 0.5~1mm, and after the first washer 3 and the second washer 8 are pressed onto the injection molded plate, the first and second rubber rings can provide a certain degree of waterproofing.
