A restraining plate 205 is movably mounted in the opening 204, and a restraining column 206 is fixedly mounted on the upper end of the restraining plate 205, and the restraining column 206 is movably mounted in the sliding member 202. The wear-resistant component 200 also includes threaded holes 207 and mounting holes 208 respectively corresponding to the sliding plate 101 in the recess 204 and the restraining plate 205 on both sides, and screws 209 movably mounted in the threaded holes 207 and the mounting holes 208 at the upper end of the restraining plate 205. The sliding member 202 and the reinforcement sleeve 203 are both cylindrical structures, and the number of the sliding member 202 and the reinforcement sleeve 203 are both two groups.
[0027] Specifically, the automobile vacuum pump is a key component in the automobile, which is mainly used to generate negative pressure to achieve the function of exhaust or power assistance. The slides 202 movably installed on both sides of the slide 101 in the vacuum pump body 100 can be rotationally adjusted when the slide 101 rotates and moves along the inner wall of the vacuum pump body 100 to avoid the same part of the outside from continuously contacting the inner wall of the vacuum pump and being stressed, and then cooperate with the reinforcement sleeve 203 fixedly installed at its outer end to reduce the wear of the slide 202 when following the rotation of the slide 101, thereby improving the service life of the automobile vacuum pump. At the same time, after being worn, the slides 202 on both sides of the slide 101 can also be disassembled by the restraining sheet 205 on one side of the outer end, and the slide 202 can be conveniently replaced and adjusted. The restraining column 206 in the slide 202 is inserted at the upper end of the restraining sheet 205, which is mainly used for the movable restraining installation of the slide 202 so that it can rotate during use. Embodiment 2
[0028] Based on the first embodiment, Figure 4-5As shown, the lubrication component 300 includes a lubrication oil chamber 301 provided in the slide 101, and a plurality of through holes 302 arranged on both sides of the lubrication oil chamber 301 and penetrating the arc opening 201, oil seepage pads 303 are fixedly installed on both sides of the lubrication oil chamber 301, and a plurality of oil seepage strips 304 are arranged and fixedly installed on the outside of the oil seepage pads 303, and the oil seepage strips 304 are all in the through holes 302, and the lubrication component 300 also includes a filling plug 305 movably installed at the top center of the lubrication oil chamber 301, and the filling plug 305 is threadedly connected to the slide 101.
[0029] Specifically, the lubricating oil chamber 301 provided inside the slide 101, as well as the oil seepage pads 303 and oil seepage strips 304 provided on both sides of the lubricating oil chamber 301, can also lubricate the reinforcing sleeve 203 on the outside thereof when the slides 202 in the arc openings 201 on both sides of the slide 101 rotate, thereby reducing the wear during rotation and jointly improving the wear resistance and service life thereof. When the outside of the reinforcing sleeve 203 contacts the oil seepage strip 304 in the through hole 302, the upper end thereof will be lubricated by the lubricating oil in the oil seepage strip 304. The filling plug 305 installed on the upper end of the lubricating oil chamber 301 is mainly used for filling the lubricating oil.
[0030] The working principle and use process of this utility model:
[0031] When the slide 101 inside the vacuum pump body 100 rotates, the slides 202 on both sides of the slides that contact the inner wall of the vacuum pump body 100 will also rotate at the outer ends of the upper and lower restraint columns 206, thereby avoiding continuous force and friction on the same part of the outer side. At the same time, when the slide 202 rotates, the outer reinforcement sleeve 203 will also be coated with the lubricating oil in the oil seepage strip 304 when contacting the oil seepage strip 304 in the through hole 302 at the inner end of the arc opening 201, thereby lubricating the outer end of the reinforcement sleeve 203 during rotation, further reducing the friction during rotation, thereby enhancing the wear resistance of the slide 202 and improving the service life of the vacuum pump body 100.
[0032] Although the embodiments of the present invention have been shown and described, those skilled in the art will appreciate that various changes, modifications, substitutions and variations may be made to the embodiments without departing from the principles and purpose of the present invention, and that the scope of the present invention is defined by the claims and their equivalents.
