Description

Technical Field

[0001] This utility model relates to the field of motors, and in particular to a special motor anti-leakage sealing device. Background Technology

[0002] Special motors refer to motors with special requirements in design, construction or application. They are usually used in specific industries or environments. These motors can be divided into many types according to their uses and characteristics, among which waterproof motors are one type.

[0003] Waterproof motors are used in humid or underwater environments. Their output shaft is installed using a flange plate and a gasket, and a shaft seal is installed inside to ensure the sealing of the output end. When installing the waterproof motor cable, the threaded head and threaded connector are usually used for threaded installation to ensure the sealing of the cable connection. However, when the waterproof motor is in operation, it will generate a certain amount of vibration, which may cause the threaded head to loosen from the threaded connector due to vibration. This can lead to water leakage and electrical leakage at the connection, thus creating a certain defect. Utility Model Content

[0035] 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.

[0036] This utility model provides, for example Figure 1-3 The image shows a special motor anti-leakage sealing device.

[0037] Example 1: Includes a motor body 1, a cable 2, and a connecting assembly 3. The cable 2 is electrically connected to the motor body 1 via the connecting assembly 3. The connecting assembly 3 includes a connecting base 31, a connector 32, a connecting cap 33, a sealing unit 34, and a locking component 35. The connecting base 31 is fixedly mounted on the motor body 1. The connector 32 is connected to one end of the cable 2, and the outer wall of the connector 32 is inserted into the connecting base 31. That is, the cable 2 is electrically connected to the motor body 1 via the connector 32 and the connecting base 31. The connecting cap 33 is slidably sleeved on the outside of the cable 2. The threaded sleeve is fitted onto the outside of the connecting seat 31, and the sealing unit 34 is disposed inside the connecting cap 33. The sealing unit 34 is used to seal the connection between the connecting cap 33, the connecting seat 31 and the connecting head 32, thereby improving the sealing performance between the connecting cap 33, the connecting seat 31 and the connecting head 32. The locking component 35 is disposed on the motor body 1. The locking component 35 is used to lock and limit the connecting cap 33, thereby ensuring the stability of the connection between the connecting cap 33 and the connecting seat 31 and preventing the connecting cap 33 and the connecting seat 31 from loosening due to the operation of the motor body 1.

[0038] Furthermore, the sealing unit 34 includes a sealing collar 341 and a sealing gasket 342. The sealing collar 341 is fixedly sleeved on the outside of the cable 2. The sealing gaskets 342 are respectively fixed to the top and bottom of the sealing collar 341. The top of one sealing gasket 342 is pressed and fitted against the top of the inner wall of the connector cap 33, and the bottom of the other sealing gasket 342 is pressed and fitted against the connector seat 31 and the connector head 32. That is, the connector cap 33 can limit and seal the connector head 32 by pressing the sealing gasket 342 and the sealing collar 341.

[0039] Example 2: Based on Example 1, the locking assembly 35 includes a bearing ring 351, a fixing collar 352, and a locking rod 353. The bearing ring 351 is fixedly connected to the top of the motor body 1. The fixing collar 352 is fixedly sleeved on the bottom of the outer wall of the connecting cap 33. The outer wall of the locking rod 353 is slidably inserted into the bearing ring 351. The bottom of the fixing collar 352 has a locking groove in a ring array that matches the locking rod 353. The locking rod 353 engages with the locking groove, which can lock and limit the connecting cap 33, preventing the connecting cap 33 from rotating relative to the connecting seat 31.

[0040] Furthermore, the locking assembly 35 also includes a connecting ring 354, a support spring 355, a fixing rod 356, and a limiting block 357. The bottom of the supporting ring 351 has an annular groove, and the connecting ring 354 is slidably sleeved inside the annular groove. The bottom of the locking rod 353 is fixedly connected to the connecting ring 354. The support spring 355 is located at the bottom of the connecting ring 354. The top of the fixing rod 356 is fixedly connected to the top of the inner wall of the annular groove. The fixing rod 356 is slidably sleeved, and the support spring 355 is slidably sleeved outside the fixing rod 356. The limiting block 357 is fixedly connected to the bottom of the fixing rod 356. The support spring 355 can provide an elastic support force to the locking rod 353 through the connecting ring 354, thereby ensuring the stability of the locking rod 353 engaging with the locking groove. Under the action of the support spring 355, the vibration of the motor body 1 is insufficient to separate the locking rod 353 from the locking groove.

[0041] Furthermore, the locking assembly 35 also includes a connecting groove 358 and a connecting plate 359. The connecting groove 358 is located on the top of the supporting ring 351. A button 3510 is slidably sleeved on the top of the inner cavity of the connecting groove 358, and the button 3510 is misaligned with the fixing collar 352 outside the connecting cap 33. The connecting plate 359 is fixedly connected between the button 3510 and the connecting ring 354. A sliding hole matching the connecting plate 359 is provided on one side of the inner wall of the connecting groove 358. By pressing the button 3510, the button 3510 can drive the connecting ring 354 and the locking rod 353 to descend through the connecting plate 359, thereby separating the locking rod 353 from the fixing collar 352 and unlocking the connecting cap 33.

[0042] Finally, it should be noted that the above description is only a preferred embodiment of the present utility model and is not intended to limit the present utility model. Although the present utility model has been described in detail with reference to the foregoing embodiments, those skilled in the art can still modify the technical solutions described in the foregoing embodiments or make equivalent substitutions for some of the technical features.
