[0009] Furthermore, a slot is provided on the left end surface of the fixing shell corresponding to the threaded rod, and a bolt is provided on the left side of the slot, and the bolt is rotatably connected to the fixing shell.

[0010] Furthermore, a plurality of groups of diamond blocks are fixedly mounted on the right end surface of the lining plate body, and the plurality of groups of diamond blocks are evenly distributed.

[0011] Compared with the prior art, the beneficial effects of the present invention are:

[0012] 1. The utility model sets a fixing groove and an insertion rod, and when the lining plate body is installed, the insertion rod is simultaneously inserted into the fixing groove, thereby increasing the stability of the lining plate body and optimizing the installation process of the lining plate body, thereby relatively improving the convenience of the equipment.

[0021] See also Figures 1 to 4, the utility model provides a technical solution:

[0022] To achieve the above-mentioned purpose, the utility model provides the following technical solutions: a liner for an impact crusher, comprising a fixed shell 1, a liner body 2 is arranged inside the fixed shell 1, a slide groove 3 is opened on the left end face of the liner body 2, a slider 4 is slidably connected inside the slide groove 3, a threaded rod 5 is fixedly installed on the middle part of the left end face of the liner body 2, a connecting member 6 is slidably connected to the outer surface of the threaded rod 5, a connecting rod 7 is rotatably connected between one end of the connecting member 6 and the slider 4, a spring 8 is fixedly installed between the slider 4 and the inner rear end face of the slide groove 3, a transmission rod 9 is fixedly installed on the rear end face of the slider 4, and a push plate 14 is provided on the front side of the liner body 2.

[0023] The other end of the transmission rod 9 passes through the slide groove 3 and extends to the outside to be fixedly connected to the push plate 14. Three groups of insertion rods 15 are fixedly installed on the front end surface of the push plate 14.

[0024] When the lining plate body 2 is installed on the fixed shell 1, first, align the threaded rod 5 with the socket 10, and extend the threaded rod 5 out of the socket 10, and twist the bolt 11 to fix the installation. At the same time, the lining plate body 2 and the fixed shell 1 are tightly fitted and the connecting piece 6 is squeezed, so that the connecting piece 6 is close to the lining plate body 2.

[0025] A fixing plate 12 is fixedly mounted on the inner wall of the fixing shell 1 , and a fixing groove 13 is formed on the front end surface of the fixing plate 12 corresponding to the insertion rod 15 .

[0026] The connecting rod 7 , the slide groove 3 , the slider 4 , the spring 8 , the transmission rod 9 , the push plate 14 and the insertion rod 15 are respectively provided in two groups and are symmetrically arranged. The two groups of connecting rods 7 are both rotatably connected to the connecting member 6 .

[0027] A slot is provided on the left end surface of the fixing shell 1 corresponding to the threaded rod 5 , and a bolt 11 is provided on the left side of the slot. The bolt 11 is rotatably connected to the fixing shell 1 .

[0028] The connecting member 6 drives the two sets of connecting rods 7 to make the slider 4 at the other end of the connecting rod 7 slide inside the sliding groove 3.

[0029] As the slider 4 slides, it drives the transmission rod 9 to expand to both sides and pushes the push plate 14 toward the fixed plate 12, so that the insertion rod 15 on the push plate 14 is inserted into the fixing groove 13 on the fixed plate 12, thereby completing the convenient installation of the lining body 2.
