[0017] In order to make the objectives, technical solutions and advantages of the embodiments of the present invention more clear, the following will further describe the embodiments of the present invention in detail with reference to the drawings and embodiments. It should be understood that the specific embodiments described herein are only used to explain the present invention and are not used to limit the present invention.

[0018] In the description of the embodiments of the present invention, it should be understood that the orientation or positional relationship indicated by the terms "upper", "lower", "front", "rear", "inner", "outer", etc. is based on the orientation or positional relationship shown in the drawings, and is only for the convenience of describing the embodiments of the present invention and simplifying the description, rather than indicating or implying that the device or element referred to must have a specific orientation, be constructed and operated in a specific orientation, and therefore should not be construed as a limitation to the embodiments of the present invention.

[0019] In the description of the embodiments of the present invention, it should be noted that unless otherwise clearly specified and limited, the terms "installation", "connection", and "coupling" should be understood in a broad sense. For example, it can be a fixed connection, an integral connection, or a detachable connection; it can be the communication inside two components; it can be directly connected or indirectly connected through an intermediate medium. For those of ordinary skill in the art, the specific meanings of the above terms in the embodiments of the present invention can be understood according to specific circumstances.

[0020] See Figures 1-4 As shown, an efficient cone crusher liner in an embodiment of the present utility model includes an inner liner 1 and an outer liner 2. A plurality of symmetrically arranged connecting rods 3 are fixedly connected to the outer wall of the inner liner 1. Connection grooves 4 are provided at positions of the outer liner 2 corresponding to each connecting rod 3. A rotating ring 5 is rotatably connected to the top end of the inner liner 1. A plurality of fixedly connected fixing blocks 6 are arranged in an array on the rotating ring 5. A plurality of first threaded grooves 7 are arranged in an array on the rotating ring 5. Fixing bolts 8 are threadedly connected to the interiors of the plurality of first threaded grooves 7. Second threaded grooves 9 are provided at positions of the top end of the inner liner 1 corresponding to the first threaded grooves 7. A plurality of limiting rings 10 are fixedly connected to the top end of the outer liner 2. Limiting grooves 11 are provided in the interiors of the plurality of limiting rings 10.

[0021] Both the connecting rods 3 and the connection grooves 4 are provided with four. The connecting rods 3 are all slidably connected to the interiors of the connection grooves 4. The connection between the connecting rods 3 and the connection grooves 4 can prevent the outer liner 2 from rotating.

[0022] Both the fixing bolts 8, the first threaded grooves 7, and the second threaded grooves 9 are provided with four. The bottom ends of the fixing bolts 8 are all threadedly connected to the second threaded grooves 9. The connection between the second threaded grooves 9 and the fixing bolts 8 facilitates fixing the rotating ring 5.

[0023] Both the fixing blocks 6 and the limiting rings 10 are provided with four. The fixing blocks 6 are all slidably connected to the interiors of the limiting grooves 11. The connection between the fixing blocks 6 and the limiting grooves 11 facilitates fixing the outer liner 2.

[0024] The outer liner 2 is sleeved on the outer wall of the inner liner 1.

[0025] When using the embodiment of the present utility model, the inner liner 1 and the outer liner 2 rotate inside the crusher to crush stones. The frictional force with the stones is all borne by the outer liner 2. When the outer liner 2 is worn too much, rotate the fixing bolts 8 and take out the fixing bolts 8 from the interiors of the first threaded grooves 7 and the second threaded grooves 9. At this time, the fixation of the rotating ring 5 is released, and the rotating ring 5 can be directly rotated. The rotation of the rotating ring 5 will drive the four fixing blocks 6 to rotate together, and move the plurality of fixing blocks 6 out of the limitation of the limiting grooves 11. The fixing blocks 6 no longer block the limiting rings 10. At this time, the outer liner 2 can be directly lifted up and removed. The installation of the outer liner 2 is the same. The structure of the present utility model is simple and the cost is low.

[0026] The basic principle of the present invention has been shown and described above. The above is only the preferred embodiment of the present invention and is not intended to limit the present invention. The descriptions in the above embodiments and the specification only illustrate the principle of the present invention. Without departing from the scope of the present invention, any modifications, equivalent substitutions, improvements, etc. made within the spirit and scope of the present invention shall be included within the protection scope of the present invention.
