DETAILED DESCRIPTION

[0031] The following will be combined with the drawings in the embodiments of the utility model to clearly and completely describe the technical solutions in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments in the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.

[0032] Reference Figure 1 , Figure 2 and Figure 3The utility model provides an embodiment: a high-strength wear-resistant sleeve plate, including a shell 1, circular grooves 3 are provided at both ends of the shell 1, a hollow column 4 is provided inside the shell 1, and sliding rings 5 ​​are fixedly connected at both ends of the hollow column 4, and sliding grooves 6 are provided on the outer walls of the two sliding rings 5, and multiple rolling balls 7 are rotatably connected to the inside of the two sliding grooves 6 at equal intervals, and grooves 10 are equidistantly provided around the inside of the shell 1, and springs 9 are fixedly connected to one side of the multiple grooves 10, and multiple springs One end of the spring 9 is fixedly connected with a cylinder 8, one end of each of the cylinders 8 is slidably connected to the outer wall of the hollow column 4, a lubricating plate 11 is fixedly connected to the inner wall of the hollow column 4, the bottom end of the housing 1 is rotatably connected with a bottom cover 12, the top of the housing 1 is provided with a mounting mechanism 2, the mounting mechanism 2 is used for quick installation of the sleeve, a limiting groove 13 is provided on the top of the bottom cover 12, the limiting groove 13 is slidably connected to the bottom end of the hollow column 4, the lubricating plate 11 is consistent in size with the hollow column 4, and the lubricating plate 11 is made of graphite;

[0033] Specifically, the shaft must pass through the hollow column 4. When the shaft is in motion, the friction between the shaft and the hollow column 4 is reduced by rotating the lubrication plate 11. At the same time, when the shaft rotates and applies force to the hollow column 4, the hollow column 4 rotates accordingly, thereby driving the sliding rings 5 ​​at both ends to rotate, and the rolling balls 7 in the sliding grooves 6 of the sliding rings 5 ​​also rotate accordingly. The rotation of the rolling balls 7 in the grooves 3 further reduces the friction with the outer shell 1. When the outer shell 1 is hit, the side that is subjected to force will move inward, causing the cylinder 8 to contact the shaft, thereby applying pressure to the spring 9. At this time, the spring 9 shares the pressure by compression, thereby reducing the impact on the shaft.

[0034] Reference Figure 4 and Figure 5 The mounting mechanism 2 includes a limiting ring 201, which is fixedly connected to the top outer wall of the housing 1, and a buckle 202 is fixedly connected to the top of the limiting ring 201 at an equal distance, and a fixing ring 203 is arranged on the top of the limiting ring 201, and a plurality of slots 204 are equidistantly provided at the bottom of the fixing ring 203, and a plurality of limiting bolts 205 are rotatably connected to the bottom of the limiting ring 201 at an equal distance;

[0035] Specifically, during the installation of the sleeve, the fixing ring 203 should first be positioned and fixed at the specified position, and then the top buckle 202 of the limiting ring 201 should be aligned with the slot 204 and inserted, and then the limiting ring 201 should be rotated to the right to ensure that the buckle 202 is firmly inserted into the slot 204. At this time, align the limiting bolt 205 with the reserved hole, pass through the limiting ring 201 and the fixing ring 203 in turn, and fix the limiting bolt 205 by turning the nut 16.

[0036] Reference Figure 4The bottom of the fixed ring 203 is fixedly connected with a positioning ring 14, and the top of the limiting ring 201 is provided with a positioning groove 15, the positioning ring 14 is slidably connected with the positioning groove 15, and the size of the positioning ring 14 is consistent with that of the positioning groove 15;

[0037] Specifically, the positioning ring 14 and the positioning groove 15 facilitate the fixing ring 203 to fit with the limiting ring 201 , so as to facilitate accurate positioning of the limiting ring 201 .

[0038] Reference Figure 4 The tops of the plurality of limiting bolts 205 sequentially penetrate the limiting ring 201 and the fixing ring 203, the tops of the plurality of limiting bolts 205 are rotatably connected with nuts 16, the outer walls of the plurality of limiting bolts 205 are provided with gaskets 17, and the plurality of gaskets 17 are fitted with the bottoms of the corresponding nuts 16;

[0039] Specifically, the limiting bolt 205 can fix the limiting ring 201 and the fixing ring 203, and the nut 16 can reinforce the limiting bolt 205 to make it more stable.

[0040] Working principle: When using a high-strength wear-resistant sleeve, the shaft needs to pass through the hollow column 4. At this time, when the shaft moves, the lubrication plate 11 is rotated to reduce the friction between the shaft and the hollow column 4. At the same time, when the shaft rotates until the force acts on the hollow column 4, the hollow column 4 rotates to drive the sliding rings 5 ​​at both ends to rotate, so that the rolling balls 7 in the sliding grooves 6 around the sliding rings 5 ​​rotate. At the same time, the rolling balls 7 rotate in the grooves 3 to reduce the friction with the outer shell 1. When the outer shell 1 is collided, the side receiving the force moves inward to make the cylinder 8 contact the shaft, so that the cylinder 8 squeezes the spring 9. At this time, the spring 9 shares the pressure and contracts to reduce the impact on the shaft.

[0041] And when the shaft sleeve needs to be installed, the fixing ring 203 must be fixed in a predetermined position first. At this time, the buckle 202 on the top of the limiting ring 201 is aligned with the slot 204 and inserted. At the same time, the limiting ring 201 is rotated to the right so that the buckle 202 is inserted into the slot 204. At this time, the limiting bolt 205 is aligned with the reserved hole, and the limiting bolt 205 is rotated at the same time to pass through the limiting ring 201 and the fixing ring 203 in sequence. At this time, the nut 16 is rotated to fix the limiting bolt 205.

[0042] Finally, it should be noted that the above is only a preferred embodiment of the present invention and is not intended to limit the present invention. Although the present invention has been described in detail with reference to the aforementioned embodiments, those skilled in the art can still modify the technical solutions described in the aforementioned embodiments or make equivalent substitutions for some of the technical features therein. Any modifications, equivalent substitutions, improvements, etc. made within the spirit and principles of the present invention should be included in the protection scope of the present invention.
