Description

Technical Field

[0001] This utility model belongs to the field of fastener technology, specifically relating to a self-tapping plastic threaded nail. Background Technology

[0002] Self-tapping screws are widely used for fixing soft materials such as wood and drywall due to their self-threaded design and the elimination of the need for pre-drilling. However, in situations requiring the installation of a large number of screws, such as installing insulation boards or fixing conduits, workers must individually pick up, align, and screw in the screws, which is inefficient and prone to scattering. Existing screw banks are mostly made of metal, which is costly and not insulated; while some plastic clip-on arrangements have problems such as insufficient clamping force, easy screw dislodgement, or uncontrollable installation angles. Therefore, a solution is needed that can reliably fix screws, enable rapid and continuous installation, and is cost-effective. Summary of the Invention

[0003] The present invention aims to solve the technical problems existing in the prior art and provide a self-tapping plastic threaded nail.

[0004] The above-mentioned technical problems of this utility model are mainly solved by the following technical solution: a self-tapping plastic threaded pin, comprising a plastic mounting strip and a plurality of self-tapping pins, characterized in that: the plastic mounting strip is provided with a plurality of sockets, and the plurality of self-tapping pins are inserted into the sockets.

[0005] Preferably, the plurality of sockets are equidistantly spaced on the front end face of the plastic mounting strip, with each socket having a 45° angle with the plastic mounting strip.

[0006] Preferably, the socket includes two clamping pieces, the base of which is fixed to a plastic mounting strip, the top of which is bent and overlaps each other, the two corners of the two clamping pieces overlap and connect each other, and a guide crack is formed between the two connection positions.

[0007] Preferably, the plastic mounting strip has a hollowed-out groove at the position corresponding to each socket.

[0008] Preferably, a guide slide is provided on both sides of the back of the plastic mounting strip, and the two guide slides are arranged parallel to the plastic mounting strip as a whole.

[0009] Preferably, the distance between the two engagement pieces is smaller than the diameter of the self-tapping screw, and the self-tapping screw is held in place within the socket.

[0010] The beneficial effects of this utility model are: by integrating and arranging multiple self-tapping screws, continuous and rapid access and installation can be achieved, which significantly improves construction efficiency and is particularly suitable for large-scale fixed operations.

[0011] Utilizing an elastic interlocking plate structure with interference fit, and through the design of corner overlap and guide cracks, the socket can firmly hold the self-tapping screw, effectively preventing the screw from loosening during transportation and operation. At the same time, the guide crack is designed so that the overlap breaks directly and quickly releases the self-tapping screw when the electric screwdriver is used to tighten it.

[0012] The main structure is made of plastic, allowing for mass production at low cost through injection molding. The guide rail design on the back enables it to be adapted to specialized tools, expanding its automation application scenarios. Attached Figure Description

[0013] Figure 1 This is a schematic diagram of the structure of this utility model; Figure 2 This is a schematic diagram of the structure of a socket according to this utility model; Figure 3 This is a schematic diagram of a hollowed-out groove according to this utility model.

[0014] In the diagram: 1. Plastic mounting strip; 2. Self-tapping screw; 3. Socket; 31. Clamping piece; 32. Guide crack; 4. Hollow groove; 5. Guide slide. Detailed Implementation

[0015] The technical solution of this utility model will be further described in detail below through embodiments and in conjunction with the accompanying drawings.

[0016] Example: A self-tapping plastic threaded staple, such as Figures 1-3 As shown, it includes a plastic mounting strip 1 and a number of self-tapping screws 2, characterized in that: the plastic mounting strip 1 is provided with a number of sockets 3, and a number of self-tapping screws 2 are inserted into the sockets 3; the number of sockets 3 are equidistantly arranged on the front end face of the plastic mounting strip 1, and each socket 3 has a 45° angle with the plastic mounting strip 1.

[0017] The socket 3 includes two clamping pieces 31. The base of the clamping pieces 31 is fixed to the plastic mounting strip 1, and the top is bent and overlapped with each other. The two corners of the two clamping pieces 31 overlap and connect with each other, and a guide crack 32 is formed between the two connection positions.

[0018] The plastic mounting strip 1 has a hollowed-out groove 4 at the position corresponding to each socket 3; a guide slide 5 is provided on both sides of the back of the plastic mounting strip 1, and the two guide slides 5 are arranged parallel to the plastic mounting strip 1 as a whole; the distance between the two clamping pieces 31 is less than the diameter of the self-tapping screw 2, and the self-tapping screw 2 is stuck in the socket 3.

[0019] The principle of this utility model: The plastic mounting strip 1 is integrally molded by injection molding, and multiple sockets 3 on it are arranged at a preset 45° angle. Each socket 3 is composed of two elastic clamping pieces 31, the top corners of the clamping pieces 31 overlap each other to form a stable ring structure, with a guide slit 32 left in the middle.

[0020] During assembly, the elasticity of the retaining piece 31 is used to force the shank of the self-tapping screw 2 into the socket 3 along the guide crack 32. Since the distance between the two retaining pieces 31 is smaller than the diameter of the self-tapping screw 2 in its natural state, the self-tapping screw 2 is tightly held in the socket 3 and will not fall off due to shaking or inversion.

[0021] During installation, workers or automated equipment can hold the plastic mounting strip 1 and use tools such as an electric screwdriver to align and tighten each self-tapping screw 2 in sequence. During tightening, the self-tapping screw 2 rotates and applies downward force, its head opening the overlap of the retaining piece 31, thus smoothly detaching from the plastic mounting strip 1 and completing the fixation. The hollowed-out groove 4 on the back of the plastic mounting strip 1 provides the necessary deformation space for this process, preventing the plastic parts from breaking. The guide rails 5 on both sides can be used with a specially designed screw feeder to achieve fast, continuous, and automated installation.

[0022] Finally, it should be noted that the above embodiments are merely representative examples of this utility model. Obviously, this utility model is not limited to the above embodiments and can have many variations. Any simple modifications, equivalent changes, and alterations made to the above embodiments based on the technical essence of this utility model should be considered to fall within the protection scope of this utility model.
