DETAILED DESCRIPTION

[0018] In order to make the purpose, technical solution and advantages of the utility model clearer, the technical solution of the utility model will be described clearly and completely below. Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments of the utility model, all other embodiments obtained by ordinary technicians in this field without creative work belong to the scope of protection of the utility model.

[0019] The specific implementation of the utility model will be described below in conjunction with the accompanying drawings:

[0020] like Figures 1 to 4 As shown, a wire tube glue sealing structure of a gear box 1 includes a wire tube groove 2 and a cover 3. The wire tube groove 2 is integrated with the gear box 1, and a first wire tube 21 is provided at the bottom of the wire tube groove 2. The cover 3 is provided on the top surface of the wire tube groove 2, and a plurality of second protrusions 35 are symmetrically distributed on the cover 3. The wire tube groove 2 is provided with a first protrusion 25 at a position corresponding to the second protrusion 35, and a threaded hole is provided on the first protrusion 25. The second protrusion 35 is provided with a bolt, and the bolt passes through the second protrusion 35 and is screwed into the threaded hole. The detachable cover 3 facilitates the subsequent glue filling and assembly of other components.

[0021] The electric wire 4 passes through the first wire tube 21 and the cover 3 to the outside of the gear box 1. A sealing plug 22 is provided in the first wire tube 21, and the electric wire 4 is interference fit with the first wire tube 21 through the sealing plug 22. The sealing plug 22 improves the sealing performance of the assembly of the electric wire 4 and the first wire tube 21. The sealing plug 22 includes a bottom plug 221 and a pipe plug 222, and the wire tube groove 2 is provided with a groove 211 that matches the bottom plug 221. In the process of the electric wire 4 passing through the sealing plug 22, the bottom plug 221 cooperates with the groove 211 to prevent the sealing plug 22 from being completely taken out of the first wire tube 21 by the electric wire 4. The outer wall of the pipe plug 222 fits with the inner wall of the first wire tube 21, and the inner wall of the pipe plug 222 fits with the electric wire 4. The wire tube fills the gap between the electric wire 4 and the first wire tube 21 to prevent water droplets from penetrating into the gear box 1 from the gap between the electric wire 4 and the first wire tube 21.

[0022] The sealing cover 3 and the bottom surface of the wire tube groove 2 form a glue layer 23, and the height of the glue layer 23 is higher than the height of the first wire tube 21. Before assembling the sealing cover 3, UV glue is injected into the glue layer 23. After the UV glue is cured, the first wire tube 21 is completely immersed under the glue layer 23. Water droplets are prevented from penetrating from the gap between the first wire tube 21 and the sealing plug 22.

[0023] The bottom surface of the cover 3 is provided with a bottom groove 31, in which an elastic block 32 is embedded. The elastic block 32 and the bottom groove 31 are interference fit, and the elastic block 32 is provided with a through hole 321 that matches the pipe plug 222. The side wall of the bottom groove 31 is provided with a chamfer 311 that matches the elastic block 32. The elastic block 32 is embedded in the bottom groove 31 along the chamfer 311 and undergoes contraction deformation, resulting in radial pressure on the circumference of the pipe plug 222 that matches the through hole 321, so that the pipe plug 222 and the elastic block 32 maintain an interference fit state, preventing water from penetrating into the gap between the elastic block 32 and the pipe plug 222. The outer wall of the bottom groove 31 is provided with a sealing ring 34, and the top surface of the wire pipe groove 2 is provided with a side groove 24 that matches the sealing ring 34. The sealing performance of the assembly of the cover 3 and the wire pipe groove 2 is improved by the cooperation between the sealing ring 34 and the side groove 24. The top surface of the cover 3 is provided with a second wire tube 33 that matches the wire 4 , and the second wire tube 33 is used to keep the wire 4 in the elastic block 32 in a stable state to prevent the wire 4 from being frequently disturbed and forming a gap between the elastic block 32 into which water can enter.

[0024] The working principle of the specific embodiment of the utility model is as follows: the sealing plug 22 is assembled into the first wire tube 21, and the wire 4 passes through the first wire tube 21 and the cover 3. UV glue is injected into the glue layer 23, and the UV glue covers the first wire tube 21. After the UV glue is cured, the cover 3 is assembled. The upper part of the pipe plug 222 is embedded in the through hole 321, and the pipe plug 222 and the elastic block 32 are interference-fitted. The cover 3 is fixedly matched with the wire tube groove 2 through the cooperation of the first protrusion 25, the second protrusion 35 and the bolt.
