Detailed implementation manners

[0021] Next, the technical solutions in the embodiments of the present utility model will be clearly and completely described in conjunction with the drawings in the embodiments of the present utility model. Obviously, the described embodiments are only a part of the embodiments of the present utility model, rather than all of the embodiments.

[0022] Referring to Figures 1-5 , a wear-resistant cast iron plate fitting, including a plate body 1. An installation groove and two connection grooves are opened on the outer wall of the plate body 1. A connection block 3 is slidably installed inside the installation groove. Both outer walls of the connection block 3 are connected to the inside of the two connection grooves through a connection mechanism. The connection mechanism includes a connection plate 2 fixedly installed on the outer wall of the connection block 3, and the connection plate 2 is slidably connected to the inside of the connection groove.

[0023] A fixing groove is opened on the outer wall of the connection block 3. A fixing block 5 is slidably installed inside the fixing groove. A fixing spring 4 is installed inside the fixing groove. Two ends of the fixing spring 4 are elastically connected to the inner wall of the fixing groove and the outer wall of the fixing block 5 respectively. A fixing hole 6 cooperating with the fixing block 5 is opened on the outer wall of the plate body 1. A wear-resistant plate 7 is fixedly installed on the outer wall of the connection block 3. A sealing gasket 8 cooperating with the outer wall of the plate body 1 is fixedly installed on the inner wall of the wear-resistant plate 7. The sealing gasket 8 is made of vulcanized rubber. Vulcanized rubber refers to vulcanized rubber, which has characteristics such as not being sticky, not being easily broken, etc., and also has high elasticity, heat resistance, tensile strength, and insolubility in organic solvents, etc. A rotating groove 9 is opened on the inner wall of the installation groove. An extrusion plate 11 is fixedly connected to the inner wall of the rotating groove 9 through a reset mechanism. The reset mechanism includes a spring telescopic rod 10 fixedly installed on the inner wall of the rotating groove 9, and the telescopic end of the spring telescopic rod 10 is fixedly connected to the inner wall of the extrusion plate 11.

[0024] A rotating shaft 12 is rotatably installed inside the rotating groove 9. The outer wall of the rotating shaft 12 is connected to the inner wall of the extrusion plate 11 through an extrusion mechanism. The extrusion mechanism includes a cam 13 fixedly installed on the outer wall of the rotating shaft 12, and the cam 13 is in rotational contact with the inner wall of the extrusion plate 11. A knob 14 is fixedly installed on the outer wall of the rotating shaft 12. A wear-resistant coating 15 is provided on the outer wall of the plate body 1. The wear-resistant coating 15 is made of silicon carbide material. The hardness of the silicon carbide material is very high, and in addition, its structure is stable and its corrosion resistance is good. Therefore, it performs outstandingly in terms of wear resistance. Under harsh environments such as high temperature, high pressure, strong acid, and strong alkali, silicon carbide can still maintain its hardness and strength and is not easily damaged and worn.

[0025] When the utility model is in use, the connection block 3 can be slidably installed inside the installation groove through the cooperation of the connection plate 2 and the connection groove. When the connection block 3 completely enters the installation groove, the fixing spring 4 can drive the fixing block 5 to move into the fixing hole 6, thereby fixing the connection block 3, and thus realizing the installation and fixation of the wear-resistant plate 7. At this time, the wear-resistant plate 7 can squeeze the sealing gasket 8, and through the cooperation of the sealing gasket 8, the sealing performance between the wear-resistant plate 7 and the outer wall of the plate body 1 can be increased, avoiding dust from entering the installation groove and the connection groove and causing jamming. When the plate body 1 is in use, the wear-resistant plate 7 can contact with external objects instead of the plate body 1, thereby avoiding directly causing wear to the plate body 1 and reducing the damage to the plate body 1. Moreover, when the plate body 1 is in use, the wear-resistant coating 15 made of silicon carbide material can increase the wear-resistant performance of the outer wall of the plate body 1, thereby increasing the service life of the plate body 1;

[0026] When it is necessary to disassemble and replace the wear-resistant plate 7, the fixing block 5 can be squeezed inward to move it out of the fixing hole 6, thereby releasing the fixing of the connecting block 3. Subsequently, the knob 14 can be rotated to drive the rotating shaft 12 to rotate, and the rotating shaft 12 drives the cam 13 to rotate and squeeze the pressing plate 11. At this time, the pressing plate 11 moves under force and pulls the spring telescopic rod 10. When the pressing plate 11 contacts the connecting block 3, the connecting block 3 can be made to extend out of the installation groove under the continuous squeezing of the cam 13, thereby realizing the convenient disassembly of the connecting block 3 and thus the convenient disassembly of the wear-resistant plate 7. After the connecting block 3 is disassembled, the pressing plate 11 can be driven to move back to its original position under the elastic action of the spring telescopic rod 10, preventing the pressing plate 11 from extending out and affecting the subsequent installation of the connecting block 3.

[0027] The above is only a preferred specific embodiment of the present invention, but the protection scope of the present invention is not limited thereto. Any person skilled in the art within the technical scope disclosed by the present invention, according to the technical solution of the present invention and its inventive concept, makes equivalent replacements or changes, and should be covered by the protection scope of the present invention.
