Here, the first spring 14 is provided between the bearing plate 3 and the base 1 to achieve the restoration of the bearing plate 3 and to improve the shock-absorbing effect.

Here when the user is in the in-process of promoting when carelessly bumping with the wall, make protruding 13 atress direction deformation, realize the one-level buffering through the restoring force of protruding 13, at this moment protruding 13 deformation, make to support 16 atress and move towards the bottom of spacing groove, support 16 drive branch 17 and move by supporting, branch 17 drive sliding plate 15 slides in the spacing groove, at this moment second spring 20 is in compression state, simultaneously the stretch cord 19 here is in tensile state, realize the second grade buffering through the restoring force of second spring 20 and stretch cord 19, branch 17 removes drive auxiliary rod 22 and moves simultaneously, auxiliary rod 22 drive slider 21 moves in the bar inslot, through the frictional force between slider 21 and the bar inslot, realize tertiary buffering, the practicality of using has been improved.

The limit of the supporting rod 17 is realized through the positioning block 18, and the sliding of the supporting rod 17 is prevented, so that the sliding plate 15 can be better driven to slide in the limit groove when the supporting rod 17 is stressed.

Here, the positioning beads 24 disposed on the moving plate 4 can reduce the gap between the moving plate 4 and the sliding groove, prevent the occurrence of the phenomenon of inclination, and thus, the gap exists between the sealing plate 5 and the inner wall of the sliding groove, which affects the sealing effect, and reduce the friction force between the moving plate 4 and the sliding groove, so that the moving plate 4 can better slide in the sliding groove.

Compared with the prior art, this transfer device of commodity circulation transportation usefulness passes through damper and realizes the shock attenuation to the main part, prevent the damage of main part, realize the protection to the main part, compare with current damper, this damper passes through compressed air, realize the elastic support to bearing plate 3, simultaneously, through the compression of air, realize the operation to supporting component, realize the supplementary elastic support to bearing plate 3, prevent that bearing plate 3 atress is too big and lead to the damage, prolonged service life, here realize the protection to base 1 through anticollision institution, realize the buffering shock attenuation to base 1 through the restoring force of second spring 20 and arch 13, and the practicality of use is improved.

In light of the foregoing description of the preferred embodiment of the present invention, many modifications and variations will be apparent to those skilled in the art without departing from the spirit and scope of the invention. The technical scope of the present invention is not limited to the content of the specification, and must be determined according to the scope of the claims.
