Detailed Description

The technical solutions in the embodiments of the present invention will be clearly and completely described below with reference to the drawings in the embodiments of the present invention, and it is obvious that the described embodiments are only a part of the embodiments of the present invention, and not all of the embodiments. All other embodiments, which can be derived by a person skilled in the art from the embodiments given herein without making any creative effort, shall fall within the protection scope of the present invention.

Referring to fig. 1-2, the present invention provides the following technical solutions: the utility model provides a wear-resisting corrosion-resistant attacker for seat, includes movable rod 2, its characterized in that: connecting hole 6 has been seted up at the middle part of movable rod 2, and seat adjusting lever 1 passes connecting hole 6, and movable rod 2 is cavity, and the inside movable mounting of movable rod 2 has tight head 11 of clamp, and the tight groove 13 of clamp has been seted up towards the one end of connecting hole 6 to tight head 11 of clamp, presss from both sides tight groove 13 and seat adjusting lever 1 adaptation, presss from both sides tight head 11 and makes for the rubber material.

The inner wall of the movable rod 2 is provided with a spiral strip 7, the outer circle surface of the clamping head 11 is provided with a spiral groove 12, and the spiral groove 12 is meshed with the spiral strip 7.

The connecting rod 10 is installed to the one end of pressing from both sides tight head 11 and keeping away from connecting hole 6, and the handle 3 is installed to the one end that connecting rod 10 kept away from tight head 11, and the surface of handle 3 is provided with a plurality of clutch blocks 4.

Slider 5 is installed towards the one end of movable rod 2 to handle 3, and spout 8 has been seted up towards the one end of handle 3 to movable rod 2, and spout 8 corresponds with slider 5, and slider 5 is located the inside of spout 8.

And a supporting spring 9 is installed on one side of the sliding block 5, and one side, far away from the sliding block 5, of the supporting spring 9 is fixedly connected with the inner wall of the sliding groove 8.

The working principle is as follows: when the seat angle needs to be adjusted, handle 3 can be held by hand, friction block 4 can increase the frictional force of the person of controlling and handle 3, rotate handle 3 afterwards, handle 3 will drive connecting rod 10 synchronous revolution, connecting rod 10 can drive and press from both sides tight head 11 rotatory after rotatory, because the helicla flute 12 that presss from both sides tight head 11 surface meshes with the spiral strip 7 on the 2 inner walls of movable rod, consequently when pressing from both sides tight head 11 rotatory, the helicla flute 12 on its surface can press from both sides tight head 11 towards connecting hole 6 direction drive, press from both sides tight groove 13 and seat regulation pole 1 surface contact of tight head 11 front end until pressing from both sides tight groove, press from both sides tight head 11 this moment and the inner wall interact of connecting hole 6, adjust pole 1 centre gripping with the seat.

Then the handle 3 is rotated, the handle 3 can rotate around the connecting hole 6 and synchronously drives the seat adjusting rod 1 to rotate, the angle of the seat can be adjusted after the seat adjusting rod 1 rotates, after the adjustment of the angle of the seat is completed, the handle 3 is loosened, at the moment, each supporting spring 9 can push the sliding block 5 under the action of the self elasticity and enable the sliding block 5 to rotate in the sliding groove 8 until the sliding block 5 stops after contacting with the inner wall of the sliding groove 8, in the process, the sliding block 5 can drive the handle 3 to rotate reversely, the handle 3 can drive the clamping head 11 to rotate reversely after rotating reversely, so that the clamping head 11 is driven by the spiral groove 12 to move towards the direction far away from the connecting hole 6, the clamping head 11 is separated from the seat adjusting rod 1, at the moment, even if the handle 3 is collided by external force, the seat adjusting rod 1 cannot be driven to rotate, and the change of the angle of the seat due to accident is avoided, and potential safety hazards are reduced.

In the adjusting process, if the movable space of the handle 3 is limited, the adjustment of the seat angle cannot be completed at one time, the handle 3 can be reversely rotated after the angle is adjusted once, so that the clamping head 11 is separated from the seat adjusting rod 1, then the handle 3 is held to return to the initial position, the handle 3 is rotated, the clamping head 11 clamps the seat adjusting rod 1 again, the seat adjusting rod 1 reciprocates, and the adjustment of the seat can be completed in the limited movable space.
