Description

Technical Field

[0001] This utility model belongs to the field of coil protection technology, and specifically relates to a novel coil protection device. Background Technology

[0002] A wire guard is a common structure that is clipped onto a metal plate with a wire running through it. It is mainly used to protect the wire from being cut by the metal plate. In existing wire guard structures, the hole in the middle is mostly a flat structure. When installing the wire, it passes through the hole in the middle of the wire guard and relies on the interference between the wire surface and the wire guard to achieve the purpose of waterproofing. However, its waterproofing effect is not clear, and the wire is prone to moving back and forth, which affects the stability of the wire guard in use. Utility Model Content

[0003] The purpose of this invention is to provide a new type of coil protector with a reasonable structural design that improves the stability of use.

[0004] The technical solution to achieve the purpose of this utility model is a new type of protective coil, including a protective coil body. The outer wall of the protective coil body is provided with a locking groove for inserting a metal plate. The center of the protective coil body is provided with a through hole for passing through a wire. The inner wall of the through hole is provided with an annular groove.

[0005] The upper and lower parts of the inner wall of the through hole are integrally formed with a V-shaped pressing protrusion.

[0006] Several abutment pieces are integrally formed on the end face of the coil body, and the abutment pieces are inclined toward the center of the through hole;

[0007] The wire is inserted into the through hole, and the pressing protrusion abuts against the outer wall of the wire, while the positioning piece abuts against the outer surface of the wire to limit its movement.

[0008] A further preferred embodiment is that the number of the abutment pieces is three, and the three abutment pieces are evenly arranged around the through hole.

[0009] A further preferred embodiment is that the inner wall of the slot groove is provided with anti-slip grooves.

[0010] A further preferred embodiment is that the abutment piece is disposed on one end face of the coil protector body.

[0011] A further preferred embodiment is that the abutment piece is disposed on the symmetrical end face of the coil protector body.

[0012] This utility model has the following positive effects: The structure of this utility model is reasonably designed. An annular groove is provided in the middle of the inner wall of the coil body, which helps improve the buffering performance of the coil body. Furthermore, V-shaped pressure protrusions are provided on both the upper and lower parts of the inner wall. When the wire is inserted, the pressure protrusions press against the surface of the wire, improving the sealing performance of the connection. The V-shaped design also prevents wire displacement or loosening. The multi-point pressure also improves the sealing and waterproof performance. Additionally, a pressure plate is provided, which can press against the surface of the wire, ensuring a stable and reliable connection between the wire and the coil body, preventing wire displacement, and improving the stability of the connection.

[0018] The following will be combined with the drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the embodiments described are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without making creative efforts are within the scope of protection of the present invention.

[0019] Example 1

[0020] See Figures 1 to 2As shown, a novel coil protector includes a coil protector body 1. The outer wall of the coil protector body has a locking groove 2 for inserting a metal plate. The center of the coil protector body has a through hole 3 for a wire to pass through. The inner wall of the through hole has an annular groove 4. In this embodiment, the size of the through hole matches the wire diameter and can be processed into different sizes according to actual needs. The annular groove provides a buffer space between the upper and lower parts of the coil protector body, and, in conjunction with the pressing protrusion, prevents the wire from shifting or loosening. In practical applications, the upper and lower parts of the inner wall of the through hole are integrally formed with a V-shaped pressing protrusion 5. Several abutment pieces 6 are integrally formed on the end face of the coil protector body, and the abutment pieces are inclined towards the center of the through hole. The wire passes through the through hole, and the pressing protrusion presses against the outer wall of the wire, while the abutment pieces press against the outer surface of the wire for limitation. The abutment pieces are disposed on one end face of the coil protector body. With the above structure, the clamping action of the abutment plate and the abutment ring can prevent wire displacement and ensure the stability and reliability of the connection.

[0021] In practical applications, the number of abutment pieces is three, and the three abutment pieces are evenly arranged around the through hole. To ensure stable connection with the metal plate, anti-slip grooves 7 are provided on the inner wall of the locking groove.

[0022] This utility model has the following positive effects: The structure of this utility model is reasonably designed. An annular groove is provided in the middle of the inner wall of the coil body, which helps improve the buffering performance of the coil body. Furthermore, V-shaped pressure protrusions are provided on both the upper and lower parts of the inner wall. When the wire is inserted, the pressure protrusions press against the surface of the wire, improving the sealing performance of the connection. The V-shaped design also prevents wire displacement or loosening. The multi-point pressure also improves the sealing and waterproof performance. Additionally, a pressure plate is provided, which can press against the surface of the wire, ensuring a stable and reliable connection between the wire and the coil body, preventing wire displacement, and improving the stability of the connection.

[0023] Example 2

[0024] See Figure 3 As shown, this embodiment is basically the same as embodiment 1, except that the abutment piece is disposed on the symmetrical end face of the coil body.

[0025] The standard parts used in this embodiment can be purchased directly from the market, and the non-standard structural components described in the specification can also be directly processed according to existing technical common sense without any doubt. At the same time, the connection method of each component adopts the mature conventional means in the existing technology, and the machinery, parts and equipment all adopt conventional models in the existing technology, so no specific description is given here.

[0026] Obviously, the above embodiments of this utility model are merely examples for clearly illustrating this utility model, and are not intended to limit the implementation of this utility model. Those skilled in the art can make other variations or modifications based on the above description. It is neither necessary nor possible to exhaustively list all embodiments here. However, these obvious variations or modifications derived from the essential spirit of this utility model still fall within the protection scope of this utility model.
