Based on the embodiments in the present invention, all other embodiments obtained by a person skilled in the art without creative work belong to the protection scope of the present invention.

Examples

As shown in fig. 1-6, an anti-drop shaft sleeve comprises a shaft sleeve body 1, an oil injection mechanism 3 is arranged at the upper end of the front surface of the shaft sleeve body 1, the oil injection mechanism 3 comprises a limiting groove 302 and a sealing cover 304, the limiting groove 302 is arranged in the middle of the upper end of the front surface of the shaft sleeve body 1, a clamping mechanism 2 is arranged at the lower end of the shaft sleeve body 1, the clamping mechanism 2 comprises a fixing rod 201, the two fixing rods 201 are arranged inside a groove 101 respectively, fixing mechanisms 4 are arranged on two sides of the clamping mechanism 2, each fixing mechanism 4 comprises a fixing block 401, and each fixing block 401 is fixedly arranged on the front side and the rear side of one end, far away from a limiting plate 203, of a semicircular clamping block 210 respectively.

Through the technical scheme, establish the installation pivot back at axle sleeve body 1 endotheca, be connected with the axle through 2 counter shaft sleeve bodies 1 of clamping mechanism, avoid long-term during operation, axle sleeve body 1 produces and drops, then press from both sides tight the completion back at 2 counter shafts of clamping mechanism, fix clamping mechanism 2 through fixing mechanism 4, better messenger's axle sleeve body 1 is inseparabler with being connected between the axle, make the installation of axle sleeve body 1 more stable epaxial, at last in the long-term during operation of axle length of axle sleeve body 1 inside, very easy production wearing and tearing, thereby can carry out the oiling to 1 inside of counter shaft sleeve body through 3 counter shaft sleeve bodies of oiling mechanism, maintain counter shaft sleeve body 1 and axle, better increase the life of axle sleeve body 1 and axle.

When the oil filling pipe is specifically arranged, the oil filling pipe 301 penetrates through the middle of the inner part of the limiting groove 302, a sealing ring 303 is arranged at one end, located in the limiting groove 302, of the oil filling pipe 301, the outer side of the sealing cover 304 is in meshed connection with the inner part of the limiting groove 302 through threads, and a handle 305 is fixedly arranged in the middle of the front surface of the sealing cover 304. When needs carry out the oiling to axle sleeve body 1 inside, drive sealed lid 304 through handle 305 earlier and leave inside the spacing groove 302, then take off sealing washer 303, carry out the oiling to the inside of axle sleeve body 1 through oiling pipe 301 at last, maintain its life of better increase to axle sleeve body 1 and axle.

When the shaft sleeve is specifically arranged, the middle of the opposite surface of each limit plate 203 is respectively provided with a sliding chute 204, each groove 101 is arranged on two sides of the upper surface of the shaft sleeve body 1 and is parallel to each other, the middle of each fixed rod 201 is movably provided with the upper end of the limit frame 202 in a penetrating way, and the lower end of the opposite surface of each limit frame 202 is respectively connected with one side of the limit plate 203. When needs the counter shaft to press from both sides tightly, spacing 202 rotates through dead lever 201, drives limiting plate 203 and removes, and the counter shaft that is more convenient presss from both sides tightly and dismantles, makes the staff can be quick press from both sides tightly and separate clamping mechanism 2.

When the concrete arrangement is carried out, the slide block 206 is movably arranged in each slide groove 204, a plurality of first limiting holes 205 are respectively arranged on the front surface of each limiting plate 203 in a penetrating mode, a second limiting hole 207 is respectively arranged on the front surface of each slide block 206 in a penetrating mode, and one end of the mounting bolt 208 is respectively arranged at the position where the first limiting holes 205 and the second limiting holes 207 coincide with each other in a penetrating mode.
