Description

Technical Field

[0001] The utility model relates to the technical field of graphite copper sleeves, in particular to an anti-fracture graphite copper sleeve. Background Art

[0002] Graphite copper sleeves are widely used because the graphite attached to the copper sleeves will emit during the application process and have a lubricating effect. The existing graphite copper sleeves are mainly made of copper because copper has good wear resistance. As we all know, copper still has the disadvantage of low hardness compared to other metals, which will cause the graphite copper sleeves themselves to break due to insufficient support during use.

[0003] The existing patent (Announcement No.: CN218625085U) proposes a combined graphite copper sleeve, including a lower base; an upper base, one end of the upper base is hingedly connected to one end of the lower base; and the other end of the upper base is detachably connected to the other end of the lower base; a lower half sleeve, the lower half sleeve is detachably connected to the lower base; and an upper half sleeve, the upper half sleeve is detachably connected to the upper base; wherein the lower half sleeve and the upper half sleeve form a lubrication channel for the shaft to pass through. The utility model has the advantage of easy disassembly.

[0004] The above-mentioned graphite copper sleeve adopts a technical solution to solve the problem of easy disassembly by hingedly connecting one end of the base with one end of the lower base, and the upper half sleeve is detachably connected to the upper base. The problem with this solution is that although it solves the problem of easy disassembly, it does not solve the problem that the graphite sleeve itself has low hardness and lacks support and is prone to breakage. Therefore, we propose an anti-fracture graphite copper sleeve to solve the above problem. Utility Model Content
