[0003] The wire protection ring in the prior art is usually a simple annular rubber ring, and the wire protection ring is installed in the wire passing hole of the metal plate or other hard surface. In daily use, the cable may be dragged to transmit force to the wire protection ring, so that the wire protection ring is loose. Therefore, the wire protection ring in the related art needs to be improved and designed to enhance the connection stability between the wire protection ring and the wire passing hole. SUMMARY

[0004] To solve the above problems, the utility model provides an environmental protection type rubber seal wire protection ring.

[0005] The above technical purpose of the utility model is realized by the following technical scheme: an environmental protection type rubber seal wire protection ring, comprising a wire protection ring body, an annular mounting groove is arranged on the inner wall of the wire protection ring body, and an annular elastic member for pressing the outer wall of the wire protection ring body out of an annular protruding portion is arranged in the annular mounting groove.

[0006] By adopting the above technical scheme, the annular elastic member is arranged to form an annular protruding portion at the position corresponding to the annular mounting groove on the outer wall of the wire protection ring body. The outer diameter of the annular protruding portion is greater than the outer diameter of the wire protection ring body. The annular protruding portion cooperates with one end of the wire protection ring body with a larger diameter to ensure the stability of the connection between the wire protection ring body and the wire passing hole of the metal plate or other hard surface, and reduces the probability of the wire protection ring body being separated from the wire passing hole due to the cable being dragged.

[0007] Further, the annular elastic member comprises a circular-arc-shaped mounting plate and an elastic connecting piece hinged to one end of the circular-arc-shaped mounting plate. The circular-arc-shaped mounting plate and the elastic connecting piece are both provided with two. The two circular-arc-shaped mounting plates and the two elastic connecting pieces are alternately arranged and hinged to each other. The outer surfaces of the two circular-arc-shaped mounting plates are tightly abutted against the inner walls of the annular mounting groove away from the axis of the wire protection ring body.

[0008] By adopting the technical scheme, the elastic connecting pieces are made of materials with certain elastic deformation (such as memory metal), and the two elastic connecting pieces work together, so that the outer surfaces of the two circular-arc-shaped mounting plates are tightly abutted against the inner walls of the annular mounting groove on the side away from the axis of the wire protection coil body, so that the annular protruding part is formed at the corresponding position of the wire protection coil body outer wall and the annular mounting groove, so as to ensure the stability of the connection between the wire protection coil body and the wire passing hole, and reduce the probability of friction damage between the cable and the inner wall of the wire passing hole due to the falling of the wire protection coil body.

[0009] Further, the two ends of the circular-arc-shaped mounting plate are provided with slits for inserting the end portions of the elastic connecting pieces.

[0013] Further, the intersections between the adjacent surfaces of the circular-arc-shaped mounting plate and the intersections between the adjacent surfaces of the elastic connecting piece are all chamfered.

[0014] By adopting the technical scheme, the chamfering reduces the sharp edges on the circular-arc-shaped mounting plate and the elastic connecting piece, and reduces the probability of scratching the wire protection coil body at the annular mounting groove.

[0015] Further, the annular mounting groove has an equidistant part and a variable-distance part, the equidistant part is located on the side away from the axis of the wire protection coil body, and the distance between the top wall and the bottom wall of the variable-distance part decreases from the equidistant part towards the side close to the axis of the wire protection coil body.

[0016] By adopting the technical scheme, the opening width of the variable-distance part of the annular mounting groove on the side close to the axis of the wire protection coil body is small, which reduces the probability of the circular-arc-shaped mounting plate and the elastic connecting piece separating from the annular mounting groove.

[0017] Further, the intersection between the one end of the wire protection coil body and the outer wall of the wire protection coil body is provided with a reverse joint part, the intersection between the one end of the wire protection coil body and the inner wall of the wire protection coil body on the side close to the reverse joint part is provided with an annular sealing piece, and the inner diameter of the annular sealing piece on the side close to the annular elastic piece is smaller than the inner diameter of the annular sealing piece on the side away from the annular elastic piece.

[0018] By adopting the technical scheme, the setting of the reverse joint part reduces the difficulty of inserting the one end of the wire protection coil body with a small diameter into the wire passing hole.

[0019] Further, the sealing unit is arranged on the position of the inner wall of the wire protection coil body away from the annular sealing part, the sealing unit is composed of a plurality of arc-shaped sealing pieces, the spacing between adjacent arc-shaped sealing pieces is equal, the plurality of arc-shaped sealing pieces jointly enclose a hollow truncated cone structure, and the diameter of the truncated cone structure close to the annular sealing part is smaller than the diameter of the truncated cone structure away from the annular sealing part.

[0020] By adopting the technical scheme, the inside of the truncated cone structure composed of the plurality of arc-shaped sealing pieces abuts against the side of the cable away from the annular sealing part and the inner wall of the cable, and the stability of the connection between the cable and the wire protection coil body is enhanced.

[0021] In summary, the utility model has the following beneficial effects:

[0022] 1. In the application, the stability of the connection between the wire protection coil body and the wire passing hole of the metal plate or other hard surface is ensured, and the probability of the wire protection coil body being separated from the wire passing hole due to the cable being dragged is reduced.

[0023] 2. In the application, the elastic connecting pieces are made of materials with certain elastic deformation (such as memory metal), and the two elastic connecting pieces work together to make the outer surfaces of the two circular arc-shaped mounting plates abut against the inner wall of the side of the annular mounting groove away from the axis of the wire protection coil body, so that the outer wall of the wire protection coil body forms an annular protruding part at the corresponding position of the annular mounting groove, thereby ensuring the stability of the connection between the wire protection coil body and the wire passing hole and reducing the probability of the wire protection coil body falling off to cause friction damage between the cable and the inner wall of the wire passing hole.

[0031] The annular elastic piece 2 is arranged to form the annular protruding part 12 at the position corresponding to the annular mounting groove 11 on the outer wall of the coil protection body 1, the outer diameter of the annular protruding part 12 is greater than the outer diameter of the coil protection body 1, the annular protruding part 12 is matched with one end of the coil protection body 1 with a larger diameter, thereby ensuring the stability of the connection between the coil protection body 1 and the wire passing hole (not shown in the figure) of the metal plate or other hard surface, and reducing the probability that the coil protection body 1 is separated from the wire passing hole due to the dragging of the cable.

[0032] The annular elastic piece 2 comprises a circular arc mounting plate 21 and an elastic connecting piece 22 hinged to one end of the circular arc mounting plate 21, and the circular arc mounting plate 21 and the elastic connecting piece 22 are both provided with two, the two circular arc mounting plates 21 and the elastic connecting pieces 22 are alternately arranged and hinged to each other, and the outer surfaces of the two circular arc mounting plates 21 are both tightly abutted against the inner wall of the annular mounting groove 11 away from the axis of the coil protection body 1.

[0033] It is worth mentioning that: the elastic connecting piece 22 is made of a material with certain elastic deformation (such as memory metal), and the two elastic connecting pieces 22 work together, so that the outer surfaces of the two circular arc mounting plates 21 are tightly abutted with the inner wall of the annular mounting groove 11 away from the axis of the wire protection coil body 1, so that the outer wall of the wire protection coil body 1 and the corresponding position of the annular mounting groove 11 form an annular protruding part 12, so as to ensure the stability of the connection between the wire protection coil body 1 and the wire passing hole, and reduce the probability of friction damage between the cable and the inner wall of the wire passing hole due to the falling of the wire protection coil body 1.
