In the figure, 1, a shaft body; 2. a dust cover; 3. a seal ring; 4. a housing; 5. an adjusting sleeve; 6. a side groove; 7. a sliding block; 8. a pressing plate; 9. a spring; 10. anti-skid lines.
Detailed Description
The present utility model will be described in further detail with reference to the accompanying drawings.
Examples:
referring to fig. 1 to 3, the steering shaft with the dust cover duplex type capable of transmitting steering torque at a large angle disclosed by the utility model comprises a shaft body 1 and a dust cover 2 sleeved on the outer peripheral surface of the shaft body 1. The two ends of the dust cover 2 are fixedly connected with sealing rings 3, and the sealing rings 3 are positioned on the outer circumferential surface of the shaft body 1.
The sealing ring 3 is made of elastic material, in particular silicone rubber material or neoprene rubber material. The sealing washer 3 can take place deformation, so sealing washer 3 can be inseparabler with the laminating of axis body 1, and makes dust cover 2 can be applicable to the axis body 1 of different diameters.
The outer peripheral surface of the sealing ring 3 is fixedly connected with a shell 4, and the shell 4 is made of non-deformable materials. The outer peripheral surface of the shell 4 is connected with an adjusting sleeve 5 in a threaded manner. The outer peripheral surface of the shell 4 is provided with a plurality of side grooves 6, sliding blocks 7 are arranged on the inner side walls of the side grooves 6 in a sliding and penetrating mode, and one ends, close to the adjusting sleeve 5, of the sliding blocks 7 are arranged in a wedge-shaped mode.
The other end of the sliding block 7 is fixedly connected with a pressing plate 8, and a spring 9 is fixedly connected between the pressing plate 8 and the inner wall of the shell 4. When the spring 9 is in a natural state, the pressing plate 8 does not press the corresponding sealing ring 3, most of the wedge-shaped part of the corresponding sliding block 7 is positioned outside the side groove 6, at the moment, the adjusting sleeve 5 is rotated to drive the adjusting sleeve 5 to move towards the direction close to the sliding block 7, the adjusting sleeve 5 can contact the inclined plane of the wedge-shaped part of the sliding block 7 and push the sliding block 7 to retract into the side groove 6, the sliding block 7 drives the pressing plate 8 to move, the spring 9 stretches, and the pressing plate 8 presses the sealing ring 3, so that the sealing ring 3 is tightly attached to the outer peripheral surface of the shaft body 1 and deforms.
The pressing plates 8 are uniformly and annularly arranged, and the side grooves 6, the sliding blocks 7 and the springs 9 are uniformly and annularly arranged, so that the stress on the sealing ring 3 is uniform.
The outer peripheral surface of the adjusting sleeve 5 is provided with a plurality of anti-skid patterns 10, so that slipping caused by the rotation of the adjusting sleeve 5 by an operator is reduced, and the use of the operator is facilitated.
The implementation principle of the embodiment is as follows:
when the dust cover 2 is installed, one wedge-shaped end of the sliding block 7 is positioned in the side groove 6 and is attached to the inner wall of the adjusting sleeve 5, and the spring 9 stretches (as shown in fig. 3).
When the dust cover 2 needs to be disassembled, the adjusting sleeve 5 is rotated, the adjusting sleeve 5 is gradually far away from the sliding block 7, the sliding block 7 stretches out of the side groove 6 under the action of restoring force of the spring 9, the pressing plate 8 does not squeeze the sealing ring 3 any more, the sealing ring 3 and the shaft body 1 are in an active state, and the dust cover 2 can be taken down from the end direction of the shaft body 1 at the moment.
When the dust cover 2 is installed, after the dust cover 2 is sleeved on the end portion of the shaft body 1, the adjusting sleeve 5 is reversely rotated, the adjusting sleeve 5 is driven to move towards the direction close to the sliding block 7, the adjusting sleeve 5 can contact the inclined surface of the wedge-shaped portion of the sliding block 7, the sliding block 7 is pushed to retract into the side groove 6, the sliding block 7 drives the pressing plate 8 to move, the spring 9 stretches, the pressing plate 8 extrudes the sealing ring 3, and the sealing ring 3 is tightly attached to the outer peripheral surface of the shaft body 1.
The embodiments of the present utility model are all preferred embodiments of the present utility model, and are not intended to limit the scope of the present utility model in this way, therefore: all equivalent changes in structure, shape and principle of the utility model should be covered in the scope of protection of the utility model.
