Description

Technical Field

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

[0002] Rubber coil protectors are a common motor component. They are generally tubular in shape, with one end tapered and the other end having a raised ring on its outer wall. During assembly, the tapered end is inserted into the wire hole in the motor housing and is limited by the raised ring. Although this can meet the general usage requirements, the tapered end is prone to loosening or falling off during assembly, affecting the stability and reliability of use. Utility Model Content

[0003] The purpose of this invention is to provide a rubber coil guard structure with a reasonable structural design that is conducive to improving the stability of use.

[0004] The technical solution to achieve the purpose of this utility model is a rubber coil guard structure, including a cylindrical body, a conical insertion part integrally formed at one end of the cylindrical body, and a stop protrusion ring integrally formed on the outer wall of the other end of the cylindrical body. At least two parallel axial strip grooves are provided on the outer wall of the cylindrical body for locking into the inner wall of the mounting hole.

[0005] The retaining protrusion ring has an integrally formed retaining protrusion on the side near the tapered insertion end;

[0006] Several abutment lip rings are integrally formed on the inner wall of the cylindrical body.

[0007] A further preferred embodiment is that a plurality of inverted tooth-shaped protruding rings are integrally formed on the outer wall of the cylindrical body;

[0008] The inverted toothed convex ring and the stop convex ring achieve assembly limit.

[0009] A further preferred embodiment is that the side wall of the conical insertion portion is provided with a plurality of strip-shaped buffer grooves.

[0010] A further preferred embodiment is that the height of the locking protrusion is 0.5-1cm.

[0011] A further preferred embodiment is that the cylindrical body is a rubber structure.

[0012] This utility model has the following positive effects: Its structure is rationally designed. An axial strip groove is provided on the outer wall of the cylindrical body. During assembly, this groove engages with a protrusion on the inner wall of the mounting hole, allowing the protrusion to snap into the axial strip groove. This improves the stability and reliability of the assembly and helps prevent loosening or detachment. Furthermore, the abutment ring has a locking protrusion that engages with a locking hole on the outer surface of the mounting position to achieve insertion and positioning, further preventing loosening or detachment and ensuring the stability and reliability of the assembly. Additionally, the presence of a reverse toothed protrusion ring increases the friction between the protrusion and the inner wall of the mounting hole, further enhancing the stability and reliability of the assembly.

[0017] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0018] Example

[0019] See Figures 1 to 2 As shown, a rubber coil guard structure includes a cylindrical body 1, a tapered insertion portion 2 integrally formed at one end of the cylindrical body, and a retaining protrusion 3 integrally formed on the outer wall of the other end of the cylindrical body. In this embodiment, the cylindrical body is a rubber structure. The above structures are all conventional structures in the prior art, simply applied in a simplified manner.

[0020] Meanwhile, in this embodiment, at least two parallel axial strip grooves 4 are provided on the outer wall of the cylindrical body for engaging with the protrusions on the inner wall of the mounting hole; the depth of the axial strip grooves is less than the thickness of the side wall of the cylindrical body, and during assembly, the protrusions on the inner wall of the mounting hole engage with the axial strip grooves to prevent loosening or falling off.

[0021] Furthermore, in practical applications, a locking protrusion 5 is integrally formed on the side of the tapered insertion end of the abutment ring; several abutment lip rings 6 are integrally formed on the inner wall of the cylindrical body. The height of the locking protrusion is 0.5-1cm. The abutment ring is attached to the outer surface of the mounting part, and the locking protrusion is engaged in the locking hole on the outer surface of the mounting part, which can ensure the stability and reliability of the installation.

[0022] In practical applications, several inverted toothed protruding rings 7 are integrally formed on the outer wall of the cylindrical body; the inverted toothed protruding rings and the abutment protruding rings achieve assembly and limiting. During assembly, the inverted toothed protruding rings abut against the inner wall of the mounting hole, increasing the friction between them and the inner wall of the mounting hole, improving the stability and reliability of the installation, and preventing loosening or falling off.

[0023] Furthermore, several strip-shaped buffer grooves 8 are provided on the side wall of the conical insertion part.

[0024] This utility model has the following positive effects: Its structure is rationally designed. An axial strip groove is provided on the outer wall of the cylindrical body. During assembly, this groove engages with a protrusion on the inner wall of the mounting hole, allowing the protrusion to snap into the axial strip groove. This improves the stability and reliability of the assembly and helps prevent loosening or detachment. Furthermore, the abutment ring has a locking protrusion that engages with a locking hole on the outer surface of the mounting position to achieve insertion and positioning, further preventing loosening or detachment and ensuring the stability and reliability of the assembly. Additionally, the presence of a reverse toothed protrusion ring increases the friction between the protrusion and the inner wall of the mounting hole, further enhancing the stability and reliability of the assembly.
