Detailed Description

The following description of the embodiments of the present utility model will be made more fully hereinafter with reference to the accompanying drawings, in which embodiments of the utility model are shown, in which some, but not all embodiments of the utility model are shown. All other embodiments, which can be made by those skilled in the art based on the embodiments of the utility model without making any inventive effort, are intended to be within the scope of the utility model.

Example 1

As shown in fig. 1 to 5, the sealed outlet board for a motor provided in embodiment 1 of the present utility model includes a base board 1, where the base board 1 is connected to a motor housing, wires in the motor may pass through the base board 1, and typically, the base board 1 is fixed on the motor housing, and an edge of the base board 1 is connected to the motor housing in a sealed manner, or is integrally formed. In order to be able to detachably seal the outlet, an outlet drum 2 is fixed on the base plate 1, from which outlet drum 2 the cables of the motor can extend out of the base plate 1. An elastic gasket may be fitted over the cable extending from the end of the outlet tube 2 remote from the base plate 1, the gasket being designed to include an annular body 3 and a cylindrical body 4 fixed to the annular body 3 in order to seal a gap between the cable and the outlet tube 2. As shown in fig. 5, the cable can pass through the outlet tube 2 and the cylindrical body 4, and the axes of the annular body 3 and the cylindrical body 4 coincide. When the edge of the annular body 3 is tightly pressed on the edge of the outlet tube 2 and the cylindrical body 4 is hooped on the cable, the sealing between the outlet tube 2 and the cable can be realized, and dust and water are prevented from entering.

For this purpose, the utility model provides a sealing assembly at the end of the gasket remote from the outlet drum 2, using which the annular body 3 is pressed against the outlet drum 2 and the cylindrical body 4 against the cable.

The sealing component can adopt the structure in the prior art, for example, a thread sleeve is used, the thread sleeve is in threaded fit with the wire outlet barrel 2, the thread sleeve is screwed on the wire outlet barrel 2, an inner ring convex edge is arranged at one end of the thread sleeve, the inner ring convex edge is abutted against the annular body 3, and then the annular body 4 is sleeved on the cylindrical body 4 by using a clamp, so that the cylindrical body 4 is tightly hooped on a cable, and the sealing between the wire outlet barrel 2 and the cable is realized.

Example 2

On the basis of embodiment 1, since the clip has a connection structure at the end portion, which cannot surround the cylindrical body 4, compression of the cylindrical body 4 is formed in a range of 360 °, and thus the sealing effect is to be improved. For this reason, as shown in fig. 2 to 5, the sealing assembly designed by the present utility model includes a pressing ring 5, and a connecting piece is provided on the pressing ring 5, and is used for locking the pressing ring 5 and the outlet tube 2, and specifically, bolts can be used as connecting pieces to lock the pressing ring 5 and the outlet tube 2, so as to clamp the annular body 3, and seal between the annular body 3 and the outlet tube 2.

In order to comprehensively attach the cylindrical body 4 to the cable, six sliding grooves 7 are uniformly formed in the circumferential direction of the compression ring 5, and each sliding groove 7 points to the center of the compression ring 5. A slide 8 is slidably mounted in each chute 7. As shown in fig. 3, arc pressing blocks 6 are fixed on the part of the sliding block 8 extending out of the pressing ring 5, and the six arc pressing blocks 6 are distributed in a ring shape by taking the axial lead of the ring body 3 as the center.

When all the arc pressing blocks 6 move in the radial direction of the pressing ring 5 at the same time, the cylindrical body 4 can be pressed toward the cable. In order to fully surround the cylindrical body 4, as shown in fig. 3 and 4, two adjacent arc pressing blocks 6 are staggered and part of the side walls are attached, so that under the cooperation of all the arc pressing blocks 6, the complete coverage of the cylindrical body 4 for one circle can be ensured. It should be noted that the arc of the arc pressing block 6 is adapted to the cylindrical body 4 and the cable.

Considering the installation and spacing problem of the slider 8 on the chute 7, as shown in fig. 3, the chute 7 does not penetrate the compression ring 5, meanwhile, a spacing ring 17 is sleeved on the compression ring 5, the spacing ring 17 can be in threaded fit with the compression ring 5, when the slider 8 is put into the chute 7, the spacing ring 17 is screwed on the compression ring 5, and the moving range of the slider 8 can be limited, so that the slider 8 is prevented from being separated from the chute 7.

In order to drive the six sliding blocks 8 to move towards the axial line direction of the pressing ring 5 at the same time, the inclined plane 9 is formed in the part of the sliding blocks 8 extending out of the pressing ring 5, and meanwhile, a locking sleeve 10 which is concentric with the pressing ring 5 and can axially move along the pressing ring 5 is arranged on one side of the pressing ring 5 away from the annular body 3, and the locking sleeve 10 can be in threaded fit with the pressing ring 5. As shown in fig. 5, when the locking sleeve 10 is driven to move towards the compression ring 5, the inner cavity of the locking sleeve 10 matched with the inclined surface 9 can push the sliding block 8, so that the sliding block 8 moves towards the axial line direction of the compression ring 5, the arc-shaped pressing block 6 is used for hooping the cylindrical body 4 on a cable, and the cylindrical body 4 is in sealing connection with the cable.

One end of the locking sleeve 10, which is close to the compression ring 5, can be sleeved on the compression ring 5, and shielding of the sliding block 8 and the arc pressing block 6 is formed, and meanwhile, the function of protecting a sealing gasket can be achieved.

Example 3

On the basis of the embodiment 2, considering that the clamping ring 5 is matched with the outlet barrel 2 to clamp the annular body 3, and meanwhile, the locking sleeve 10 can also be locked with the clamping ring 5, the utility model can be provided with a connecting piece on the clamping ring 5. As shown in fig. 2 and 3, the connecting members are symmetrically disposed at both sides of the pressing ring 5, and each connecting member includes a first screw post 11 and a second screw post 12 fixedly connected with the pressing ring 5. Then, the first lug plate 13 is fixed on the outlet tube 2, and the second lug plate 14 is fixed on the locking sleeve 10. Then the first threaded post 11 passes through the first lug plate 13, the first nut 15 is installed on the end part of the first threaded post 11 in a threaded manner, and the press ring 5 and the outlet barrel 2 can be locked by rotating the first nut 15. The second threaded post 12 is threaded through the second lug plate 14 and a second nut 16 is threadedly mounted on the end of the second threaded post 12 such that rotation of the second nut 16 urges and locks the locking sleeve 10 toward the compression ring 5.
