Description

Technical Field

[0001] The utility model relates to the technical field of waterproof motor casings, in particular to a waterproof wire outlet structure for a differential motor casing. Background Art

[0002] The differential motor housing is the external structure of the motor. It not only protects the internal components of the motor from physical damage, but also supports the weight of the motor and provides an installation interface. Differential motors often face challenges in waterproofing and heat dissipation during design, especially in the motor outlet. It is necessary to ensure good sealing performance even in harsh environments. The waterproof outlet structure is designed to solve this problem. It allows the motor's wires or cables to be led out from the inside of the housing while preventing moisture from invading the motor.

[0003] At present, during the use of the existing differential motor casing waterproof outlet structure, the differential motor casing waterproof outlet structure is mostly wrapped by an integral sheath. When the differential motor cable passes through the sheath for use, the installation of the sheath is relatively inconvenient. If the sheath is difficult to disassemble and assemble, then regular maintenance and inspection work will become complicated, which may cause potential problems to be unable to be discovered and repaired in time. When quick repair or replacement of parts is required, the sheath that is inconvenient to disassemble and assemble will significantly increase downtime and affect production efficiency. In order to solve this technical problem, the utility model proposes a differential motor casing waterproof outlet structure. Utility Model Content

[0021] In order to make the technical means, creative features, objectives and effects achieved by the present invention easier to understand, the present invention is further described below in conjunction with specific implementation methods.

[0022] like Figure 1 、 Figure 2 、 Figure 3 、 Figure 4 and Figure 5 As shown, a waterproof outlet structure of a differential motor housing;

[0023] It includes a No. 1 combination sleeve 1 and a No. 2 combination sleeve 5. The top of the No. 2 combination sleeve 5 and the No. 1 combination sleeve 1 are both provided with an installation groove 10. The top of the No. 2 combination sleeve 5 and the No. 1 combination sleeve 1 are both provided with a clamping groove 14. The inside of the clamping groove 14 is provided with a positioning hole 15. A positioning ring 11 is provided inside the installation groove 10. A clamping plate 12 is provided on the inner side of the positioning ring 11, and the clamping plate 12 is inserted into the clamping groove 14. A rubber column 13 is provided at the bottom end of the clamping plate 12, and the rubber column 13 is inserted into the positioning hole 15.

[0024] The No. 1 combination sleeve 1 and the No. 2 combination sleeve 5 can be combined to form a sheath shape. The installation groove 10 is opened at the top of the No. 2 combination sleeve 5 and the No. 1 combination sleeve 1. The installation groove 10 opened at the top of the No. 2 combination sleeve 5 and the No. 1 combination sleeve 1 provides an installation space for the positioning ring 11. The positioning ring 11 is set on the top of the No. 2 combination sleeve 5 and the No. 1 combination sleeve 1 after the combination. At this time, the card plate 12 set on the inner side of the positioning ring 11 is inserted into the card groove 14, and the rubber column 13 set at the bottom end of the card plate 12 is inserted into the positioning hole 1 5, the diameter of the rubber column 13 is slightly larger than the inner diameter of the positioning hole 15, and the rubber column 13 is squeezed and deformed to be inserted into the positioning hole 15. At this time, the positioning ring 11 can be set at the top of the No. 2 combination sleeve 5 and the No. 1 combination sleeve 1. The positioning ring 11 can be used to position the No. 2 combination sleeve 5 and the No. 1 combination sleeve 1 after combination, which is convenient for the subsequent regular maintenance and inspection work to disassemble and assemble the sleeve. The structure is simple and practical, effectively reducing the downtime of the differential motor and improving production efficiency.

[0025] like Figure 1 、 Figure 2 、 Figure 3 、 Figure 4 and Figure 5 As shown, a waterproof outlet structure of a differential motor housing;

[0026] Bolts 2 are provided inside the No. 1 combination sleeve 1 and the No. 2 combination sleeve 5, and a sealing rubber layer 3 is provided inside the No. 1 combination sleeve 1 and the No. 2 combination sleeve 5. A connecting plate 4 is provided on the front of the No. 1 combination sleeve 1, and a connecting groove 9 is provided on the back of the No. 2 combination sleeve 5, and the connecting plate 4 is inserted into the connecting groove 9.

[0027] The No. 1 combination sleeve 1 and the No. 2 combination sleeve 5 are positioned on the differential motor housing by means of bolts 2. The sealing adhesive layer 3 at the bottom ends of the No. 1 combination sleeve 1 and the No. 2 combination sleeve 5 can ensure the sealing between the No. 1 combination sleeve 1 and the No. 2 combination sleeve 5 and the differential motor housing. After the joint plate 4 provided on the front side of the No. 1 combination sleeve 1 is inserted into the joint groove 9 provided on the back side of the No. 2 combination sleeve 5, the No. 1 combination sleeve 1 and the No. 2 combination sleeve 5 can be spliced.

[0028] like Figure 1 、 Figure 2 、 Figure 3 、 Figure 4 and Figure 5 As shown, a waterproof outlet structure of a differential motor housing;

[0029] The interior of the No. 1 combination sleeve 1 and the No. 2 combination sleeve 5 are both provided with a support plate 6, and the other end of the support plate 6 is provided with a clamping shell 7, and the clamping shell 7 is in the shape of a semicircular cylinder. The top inner walls of the No. 1 combination sleeve 1 and the No. 2 combination sleeve 5 are both provided with a rubber shell 8, and the rubber shell 8 is in the shape of a semi-conical cylinder. The top ends of the No. 1 combination sleeve 1 and the No. 2 combination sleeve 5 are provided with a thermoplastic tube 16, and the interior of the thermoplastic tube 16 is provided with a cable 17, and the cable 17 is movable through the interior of the clamping shell 7 and the rubber shell 8.

[0030] The inner sides of the No. 1 combination sleeve 1 and the No. 2 combination sleeve 5 are both provided with an inclined support plate 6. After the No. 1 combination sleeve 1 and the No. 2 combination sleeve 5 are combined, the two groups of clamping shells 7 at one end of the support plate 6 can be combined into a cylindrical shape. The two groups of clamping shells 7 can clamp and position the cable 17 to prevent the cable 17 from loosening when the cloth is pulled. After the two groups of rubber shells 8 are combined, they can be wrapped around the outside of the cable 17. The rubber shells 8 are used to wrap and contact the cable 17, which not only improves the waterproofness of the waterproof outlet structure of the casing, but also further strengthens the positioning of the cable 17. The thermoplastic tube 16 uses its heat shrinkage to serve as an insulating sheath for the exposed metal wire. After heating, the thermoplastic tube 16 can shrink and tightly wrap around the component that needs to be insulated. After cooling, the shape is fixed, providing good insulation performance and mechanical protection. The thermoplastic tube 16 can be made of a variety of thermoplastic plastics, such as polyethylene (PE), polypropylene (PP), polyvinyl chloride (PVC), etc. These materials soften when heated and harden when cooled. This physical change is reversible, allowing the thermoplastic tube 16 to be reused and reshaped without affecting the disassembly and assembly of the No. 1 combination sleeve 1 and the No. 2 combination sleeve 5.
