Detailed Description

The present application is described in further detail below with reference to figures 1-2.

The embodiment of the application discloses buffer for transfer cart. Referring to fig. 1, buffer for transfer car includes cylindric butt post 1, is fixed with circular flexure strip 2 through the glue adaptation on the axle lateral wall of butt post 1, and in this embodiment, the material of flexure strip 2 can be isoprene rubber. When other transfer vehicles collide with the abutting column 1, the elastic piece 2 can reduce the probability of damage caused by violent collision of other transfer vehicles with the abutting column 1 by utilizing the elasticity of the elastic piece.

Referring to fig. 2, a first elastic member 3 is coaxially welded to a side wall of the abutment column 1 away from the elastic sheet 2, and in this embodiment, the first elastic member 3 may be a spring. The butt joint post 1 is placed in cylindric buffering post 4 with first elastic component 3 is coaxial, and the one end that butt joint post 1 was kept away from to first elastic component 3 welds with the inner bottom lateral wall of buffering post 4, and butt joint post 1 slides and sets up in buffering post 4, and the one end that first elastic component 3 was kept away from to butt joint post 1 extends buffering post 4.

Referring to fig. 1 and 2, one end of the buffer column 4, which is far away from the abutting column 1, is coaxially inserted into the cylindrical fixing column 5 in an interference fit manner, the circumferential side wall of the buffer column 4 is coaxially sleeved with an annular tolerance ring 6 in an interference fit manner at a position between the fixing column 5 and the abutting column 1, when the buffer column 4 and the fixing column 5 collapse, the buffer column 4 slides in the fixing column 5, the tolerance ring 6 is gradually abutted against the side wall of the fixing column 5 in the sliding process of the buffer column 4, along with the movement of the buffer column 4, the tolerance ring 6 is fixed at a position at one side, which is far away from the transfer vehicle, of the fixing ring due to the abutment against the fixing ring, at the moment, the buffer column 4 generates friction with the inner side wall of the tolerance ring 6, and the friction force between the buffer ring and the tolerance ring 6 offsets the impact force.

Referring to fig. 2, the inner side wall of the fixing column 5 is provided with a blocking mechanism 7 at a position where the buffer column 4 is far away from the abutting column 1, the blocking mechanism 7 includes a plurality of rectangular accommodating grooves 71 and rectangular limiting pieces 72, and in this embodiment, the number of the accommodating grooves 71 and the limiting pieces 72 may be four. The containing grooves 71 are uniformly and circumferentially formed on the inner side walls of the fixing columns 5. The limiting piece 72 is vertically welded at one end of the bottom side wall of the accommodating groove 71 close to the buffer column 4. When the buffer column 4 slides in the fixed column 5, the buffer column 4 will gradually abut against the side wall of the limiting piece 72, and along with the continuous movement of the buffer column 4, the limiting piece 72 will bend towards the direction of the transfer trolley under the impact of the buffer column 4 and gradually enter the accommodating groove 71, and in the process of bending the limiting piece 72, the moving speed of the buffer column 4 will be greatly reduced.
