[0021] The sliding gap 6a is arranged in a left high and right low inclined manner, the lowest end of the right side of the sliding gap 6a corresponds to the position of the pin shaft 7, and the highest end of the left side of the sliding gap 6a extends to the left side of the pin shaft 7.

[0022] A vertical guide insertion rod 8 is arranged at the bottom of the installation slot 3a, an insertion hole is arranged on the slide block 5, the guide insertion rod 8 is inserted into the insertion hole, the upper end of the guide insertion rod 8 extends out of the top of the slide block 5, the part of the guide insertion rod 8 extending out of the slide block 5 is sleeved with a telescopic spring 9, a limiting head 10 is arranged in the installation slot 3a at the position corresponding to the upper end of the guide insertion rod 8, and the limiting head 10 limits the telescopic spring 9 on the guide insertion rod 8.

[0023] The limiting head 10 is a fixing screw rod, the rod diameter of the fixing screw rod is greater than the width of the top opening of the installation slot 3a, threaded grooves 11 are arranged at the upper ends of the side walls of the installation slot 3a and the cover plate 4 on the sides opposite to each other, the two threaded grooves 11 are matched with each other to form a threaded hole matched with the fixing screw rod, and the fixing screw rod is inserted into the threaded hole and abuts against the top end of the guide insertion rod 8.

[0024] The top end of the telescopic spring 9 is flush with the top end of the guide insertion rod 8.

[0025] The cover plate 4 is provided with mounting screw rods 12 at four end corners thereof, the base block 3 is provided with threaded holes 3b matched with the mounting screw rods 12 at four end corners thereof, and the cover plate 4 is fixedly connected with the base block 3 through the mounting screw rods 12.

[0026] Preferably, the material of the buffer strip 6 is hard rubber.

[0027] A plurality of guard covers are arranged, the buffers on each guard cover are arranged in a staggered manner, and the guard covers are inserted and assembled together.

[0028] The utility model discloses a working principle is: first, the buffer is assembled, and the slider 5 is located at the bottom of the installation groove 3a, and the lowest end of the sliding gap 6a on the buffer strip 6 corresponds and inserts with the pin shaft 7 on the slider 5, when the protective cover body 1 contracts operation, the buffer on the rear protective cover vertical board 2 will contact with the front protective cover vertical board 2, and the buffer strip 6 that extends to the left on the buffer will collide with the protective cover vertical board 2, and the buffer strip 6 that is impacted will move to the right in the movable groove 4a, and the right end of the buffer strip 6 also moves to the avoidance groove 2a on the protective cover vertical board 2, and along with the buffer strip 6 shrinking movement to the inside of the buffer, the inclined sliding gap 6a on the buffer strip 6 will also change position, since the sliding gap 6a is the structure of left high right low, so the right movement of the buffer strip 6 will make the slider 5 move up along the installation groove 3a, and in the process of the slider 5 moving up along the guide insertion rod 8, will exert external force to the extension spring 9 on the upper end of the guide insertion rod 8, since the extension spring is limited between the slider 5 and the limiting head 10, so the extension spring 9 will be forced to compress, and the buffer strip 6 will play the role of buffering in the process of moving to the right, thereby the impact between the guide rail protective cover is unloaded, and then prevents the hard collision between the protective cover body, and along with the separation between the protective cover body 1, the force acting on the buffer strip 6 also disappears, and then, the extension spring 9 that is extruded will produce the restoring force, thereby pushing the slider 5 to move down, and along with the movement of the slider 5, the buffer strip 6 will also extend to the left of the buffer again, and thus, the repeated operation of the buffer can be realized, thereby playing the role of buffering and unloading between the guide rail protective cover, and the service life of the guide rail protective cover is improved.

[0029] The embodiments of the utility model are given for example and description, and are not exhaustive or limit the utility model to the disclosed forms. Many modifications and changes are obvious to those skilled in the art. The embodiments are selected and described to better illustrate the principles and practical application of the utility model, and enable those skilled in the art to understand the utility model to design various embodiments with various modifications suitable for specific purposes.
