Two sets of connecting plates 209 are fixedly installed between each set of guide rails 208 and each set of mounting rods 202. By setting another set of wear-resistant pipes 1 inside the mounting cylinder 4, the groove of the other set of wear-resistant pipes 1 is made to fit with the outer side of the pressure plate 203. Pushing the push plate 305 moves the mounting ring 207 to slide on the outer side of the guide rail 208 through the sliding groove, moving the pressure block 206, so that the outer side of the pressure block 206 fits with the outer side of the pressure plate 203, so that the pressure plate 203 presses against the pressure plate 203, so that the outer side of the other set of flanges 301 fits with the outer side of the first set of flanges 301, so that the positioning rod 302 is set in the mounting hole of the push plate 305, and the nut 304 is threaded on the outer side of the positioning rod 302 to fix the position of the push plate 305. When the two sets of wear-resistant pipes 1 are used, they will vibrate.

The baffle 306 moves to the bottom of the opening to prevent dust from entering the opening. At this time, the other set of wear-resistant pipes 1 can be taken out. The operation is simple and convenient. The two sets of wear-resistant pipes 1 can be maintained. Compared with the traditional flange, which only uses nuts 304 to install on one side, the disassembly of nuts 304 is reduced.

The groove of the other set of wear-resistant pipes 1 is made to fit together with the outer side of the pressure plate 203. Pushing the push plate 305 moves the mounting ring 207 to slide along the guide rail 208 through the sliding groove, moving the pressure block 206, so that the outer side of the pressure block 206 fits together with the outer side of the pressure plate 203, so that the pressure plate 203 presses against the pressure plate 203, and the outer side of the other set of flanges 301 fits together with the outer side of the first set of flanges 301. The positioning rod 302 is set in the mounting hole of the push plate 305. The positioning rod 302 is threaded with a nut 304 to fix the position of the push plate 305.

The pressure plate 203 is set The slot prevents the two sets of wear-resistant pipes 1 from separating and falling off, and prevents loosening at the connection of the two sets of wear-resistant pipes 1, reducing safety hazards and improving the performance. By rotating the nuts 304 on the outside of one set of flanges 301 and the nuts 304 on the outside of push plate 305, the two sets of flanges 301 are separated. Pushing push plate 305 moves and drives installation rod 202 and pressure block 206 to move, causing pressure block 206 to separate from pressure plate 203. Installation rod 202 pushes pressure plate 203 to rotate, causing pressure plate 203 to separate from the slot. Baffle 306 moves to the bottom of the opening to prevent dust from entering. At this time, the other set of wear-resistant pipes 1 can be taken out. The operation is simple and convenient. Maintenance of the two sets of wear-resistant pipes 1 is performed. Compared with the traditional flange, which only uses nuts 304 to install on one side, it reduces the disassembly of nuts 304, reduces labor burden, and is highly practical.

However, the present utility model is not limited to the above embodiments. Within the scope of knowledge possessed by those skilled in the art, various changes can be made without departing from the spirit of the present utility model.
