[0025] The technical scheme in the embodiments of the application will be described clearly and completely below in conjunction with the drawings in the embodiments of the application. Obviously, the described embodiments are only part of the embodiments of the application, rather than all the embodiments. Based on the embodiments in the application, all other embodiments obtained by those skilled in the art without creative labor fall within the scope of protection of the application.

[0026] As Figs. 1 to 4As shown, an oil-free graphite copper sleeve comprises a sliding block 2 and a copper sleeve body 3 installed in an installation groove 21, the sliding block 2 has an installation groove 21 and an inlet 22 communicating with the installation groove 21; the copper sleeve body 3 has a break 31 corresponding to the inlet 22; the copper sleeve body 3 has two support walls 32 limiting the range of the break 31, a plurality of installation holes are formed in the support walls 32, a first graphite column 33 is installed in the installation hole, a plurality of through holes are formed in the copper sleeve body 3, and a plurality of second graphite columns 34 are installed in the through holes.

[0027] In this application, the first graphite column 33 is installed in the installation hole of the support wall 32, and the second graphite column 34 is installed in the through hole of the copper sleeve body 3. These graphite columns can continuously release graphite during work, provide good lubrication between the copper sleeve and the matching part, reduce friction resistance, reduce energy consumption, and at the same time, without the need for additional lubricating oil, avoid oil pollution, and maintenance is more convenient.

[0028] When the graphite copper sleeve is installed on the guide rail 100, the second graphite column 34 on the copper sleeve body 3 plays a lubricating role during normal sliding, and when the support wall 32 on the copper sleeve body 3 contacts the guide rail 100, the first graphite column 33 provides auxiliary lubrication when the support wall contacts the guide rail.

[0029] Specifically, the installation groove 21 is in the shape of an arc. The arc-shaped installation groove 21 is adapted to the shape of the copper sleeve body 3.

[0030] Specifically, the sliding block 2 is provided with two limiting grooves 23 located in the installation groove 21, limiting portions 24 are arranged at both ends of the limiting groove 23 to separate the limiting groove 23 and the break 31, and a snap spring 4 is installed on the limiting groove 23, at least part of the snap spring 4 is located in the installation groove 21 to limit the sliding of the copper sleeve body 3 along the installation groove 21.

[0031] The snap spring 4 installed on the limiting groove 23 provides additional limitation for the sliding of the copper sleeve along the installation groove 21, and at least part of the snap spring 4 is located in the installation groove 21, which can effectively prevent the copper sleeve from sliding excessively in the installation groove 21.

[0032] The limiting portions 24 can limit the snap spring 4 in the limiting groove 23 to prevent the snap spring 4 from falling off.

[0033] Specifically, the snap spring 4 has two dismounting ears 41, and the dismounting ears 41 have dismounting holes 411.

[0034] The two dismounting ears 41 arranged on the snap spring 4 provide a stable point of force for the operator, and when the copper sleeve needs to be dismounted, the worker can directly insert a tool into the dismounting hole 411, and then pull out the snap spring 4 from the limiting groove 23, which is more labor-saving and accurate, can greatly shorten the dismounting time, and improve the work efficiency.

[0035] Specifically, the sliding block 2 is provided with a connecting hole 25, and the copper sleeve body 3 is provided with a threaded hole 35, and the connecting hole 25 and the threaded hole 35 are used for the connection of a bolt.

[0036] The connecting hole 25 on the sliding block 2 and the threaded hole 35 on the copper sleeve can be connected through a bolt, and strong and stable fastening force can be provided, and in the process of equipment operation, the bolt connection mode can effectively prevent the relative displacement between the copper sleeve and the sliding block 2.

[0037] Specifically, the supporting wall 32 is a flat plane.

[0038] Specifically, the sliding block 2 is provided with a mounting surface 26 on the top.
