Detailed Description

The drawings in the embodiments of the present invention will be combined; the technical scheme in the embodiment of the utility model is clearly and completely described; obviously; the described embodiments are only some of the embodiments of the present invention; rather than all embodiments. Based on the embodiment of the utility model; all other embodiments obtained by a person skilled in the art without making any inventive step; all belong to the protection scope of the utility model.

Referring to fig. 1-3, a concrete protective layer cushion block for civil and industrial construction comprises a base 1, wherein the bottom end of a telescopic device 2 is connected above the base 1, and the top end of the telescopic device 2 is connected with the bottom end of a fastening layer 3.

The fastening layer 3 comprises a shell 4, the inner wall of the shell 4 is connected with a lifting plate 5 and a supporting plate 6 in a sliding mode, a strong spring 7 is connected between the lifting plate 5 and the supporting plate 6, the top end of the supporting plate 6 is provided with an arc plate 8, and the upper surface of the arc plate 8 is provided with a rubber pad 9;

the top both sides of casing 4 all are seted up flutedly, connect the one end of rotary rod 11 through rotation axis 10 in the recess, and arc supporting pad 12 is connected to the other end of rotary rod 11, and telescoping device 2 is connected to the bottom of casing 4.

The one end that the circular arc board 8 was kept away from to the recess is connected with pulley 13 through the bracing piece, is connected with the one end of string 14 on the arc supporting pad 12, and the other end of string 14 passes pulley 13 and casing 4 and lifter plate 5 fixed connection, sets up the rectangular hole that lets string 14 pass on the casing 4.
