The sealing cover 203 is rotated to open, and a proper amount of lubricating oil is poured into the lubricating oil tank 202. When the equipment is started, the lower wedge block 101 will reciprocate in the slide rail 102 on the fixed seat 100. The lower wedge block 101 will drive the connecting frame 206 to reciprocate during the reciprocating movement, so that the connecting frame 206 drives the L-shaped connecting rod 404 to reciprocate. When the L-shaped connecting rod 404 reciprocates, it will drive the linkage gear 400 to reciprocate through the cooperation with the linkage rack 405. The linkage gear 400 will drive the arc ring 401 to reciprocate. During the rotation of the arc ring 401, it will engage with the roller 40 3 contacts and drives the roller 403 to rotate.

The lubricating oil in the lubricating oil tank 202 can flow into the delivery pipe 205 through the sealing groove 308 and the flow groove 302.

[0025] Furthermore, a guide groove 304 is provided on the support frame 201, and the connecting bar 303 is slidably installed in the guide groove 304. When the roller 403 is squeezed, it will drive the connecting bar 303 to move through the fixed rod 402, and the moving connecting bar 303 will slide in the guide groove 304, thereby limiting the moving direction of the connecting bar 303.

[0026] Furthermore, a sliding hole 305 is provided on the connecting strip 303, and a guide rod 306 is slidably installed in the sliding hole 305. Both ends of the guide rod 306 are respectively fixedly installed on the inner walls of the guide groove 304 on both sides. The moving connecting strip 303 will slide on the guide rod 306 through the sliding hole 305, thereby preventing the connecting strip 303 from slipping.

[0029] Working principle of this utility model:

[0030] When the fixing seat 100 and the lower wedge block 101 need to be lubricated, the sealing cover 203 can be rotated to open and a proper amount of lubricating oil can be poured into the lubricating oil tank 202. When the equipment is started, the lower wedge block 101 will reciprocate in the slide rail 102 on the fixing seat 100. The lower wedge block 101 will drive the connecting frame 206 to reciprocate during the reciprocating movement, so that the connecting frame 206 drives the L-shaped connecting rod 404 to reciprocate. When the L-shaped connecting rod 404 reciprocates, it will drive the linkage gear 400 to reciprocate through the cooperation with the linkage rack 405, and the linkage gear 400 will drive The movable arc ring 401 reciprocates, and during the rotation of the arc ring 401, it contacts with the roller 403 and drives the roller 403 to rotate. At the same time, the reciprocating arc ring 401 repeatedly squeezes the roller 403. When the roller 403 is squeezed, it drives the connecting bar 303 to move through the fixed rod 402. The moving connecting bar 303 slides in the guide groove 304, thereby limiting the moving direction of the connecting bar 303. The moving connecting bar 303 slides on the guide rod 306 through the sliding hole 305, thereby preventing the connecting bar 303 from slipping off. The process of continuous movement of the connecting bar 303 The spring 307 will be squeezed and the flow slot 302 will be driven to move upward. The flow slot 302 moving upward will move in the flow slot 302 on the extension tube 204. At the same time, the moving linkage rod 301 will drive the sealing cover plate 300 to escape from the sealing groove 308. At this time, the lubricating oil in the lubricating oil tank 202 can flow into the delivery pipe 205 through the sealing groove 308 and the flow slot 302, and then flow into the connecting hole 208 on the connecting frame 206 through the delivery pipe 205, and then soak into the oil absorbing cotton brush 207 through the oil immersion hole 209. When the linkage rod 301 is no longer squeezed, it is in The compressed spring 307 will release and push the connecting strip 303 to reset. The reset connecting strip 303 will drive the sealing cover plate 300 to reset and cover the sealing groove 308. At this time, the lubricating oil will no longer flow, so that the oil can continue to flow during the reciprocating movement of the lower wedge block 101. The reciprocating movement of the connecting frame 206 will drive the oil-absorbing cotton brush 207 to reciprocate in the slide rail 102, and the lubricating oil will be evenly applied to the slide rail 102. The lubricating oil will be applied to the lower wedge block 101 during the reciprocating movement, so that the lower wedge block 101 can move more smoothly.
