When the connecting plate 52 moves up to drive the anti-backlash absorbing bodies 6 to move up so as to separate from the strip-shaped gap 4, the deformation compensation adjusting piece 8 passively drives the compensation absorbing bodies 62 to shrink so that the adjacent anti-backlash absorbing bodies 6 are separated from each other, thereby avoiding that static friction force is large when the compensation absorbing bodies 62 are mutually extruded and stuck, leading to large static start load and large start load fluctuation when the upward movement and the separation are carried out, and influencing the service life of the motor.
After the connecting plate 52 moves downwards to drive the anti-backlash absorbing bodies 6 to be embedded into the strip-shaped gaps 4, the deformation compensation adjusting piece 8 passively drives the compensation absorbing bodies 62 to expand, so that the adjacent anti-backlash absorbing bodies 6 are tightly attached to each other, gaps between the adjacent anti-backlash absorbing bodies 6 are avoided, the shielding effect is improved, meanwhile, the compensation is tightly attached when the expansion is realized, the friction damage to the compensation absorbing bodies 62 is reduced, and the service life of the compensation absorbing bodies 62 is prolonged.
The deformation compensation adjusting piece 8 comprises a clamping seat 81 fixed at the top of the wave absorber module 61, a U-shaped transverse frame 82 is connected in the clamping seat 81 in a lifting mode through a supporting spring, two ends of the U-shaped transverse frame 82 are slidably embedded into one side wall inside the deformation cavity 63, the U-shaped transverse frame 82 is located outside the inner section of the deformation cavity 63 and is rotationally connected with a supporting side frame 83, the other end of the supporting side frame 83 is rotationally connected with an abutting plate 84, the abutting plate 84 is fixed on the other side wall inside the deformation cavity 63, a connecting seat 821 is arranged at the middle section position of the U-shaped transverse frame 82, and the connecting seat 821 protrudes to the outer side of the clamping seat 81 and is connected with the connecting plate 52.
When the connecting plate 52 moves up to drive the gap eliminating wave absorber 6 to move up to separate from the strip-shaped gap 4, at this time, the connecting plate 52 pulls the U-shaped cross frame 82 to move up through the connecting seat 821, and the U-shaped cross frame 82 drives the compensating wave absorber 62 to shrink through the supporting side frame 83 matching with the abutting plate 84, so that the adjacent gap eliminating wave absorbers 6 are separated from each other. When the connecting plate 52 moves downwards to drive the anti-gap wave absorber 6 to be embedded into the strip-shaped gap 4, and when the anti-gap wave absorber 6 is embedded into the strip-shaped gap 4 to be static, the connecting plate 52 drives the U-shaped transverse frame 82 to move downwards, and the U-shaped transverse frame 82 drives the compensation wave absorber 62 to expand through the supporting side frame 83 matched with the abutting plate 84, so that the adjacent anti-gap wave absorbers 6 are tightly attached to each other.
While certain exemplary embodiments of the present invention have been described above by way of illustration only, it will be apparent to those of ordinary skill in the art that modifications may be made to the described embodiments in various different ways without departing from the spirit and scope of the invention. Accordingly, the drawings and description are to be regarded as illustrative in nature and not as restrictive of the scope of the invention, which is defined by the appended claims.
