Title:
MOUNTING SLEEVE
Document Type and Number:
WIPO Patent Application WO/2020/007282
Kind Code:
A1
Abstract:
A mounting sleeve (1), comprising an inner ring (11), a middle ring (12) and an outer ring (13) which are sequentially sleeved together, wherein the inner ring (11) comprises an inner ring body (111) and an inner ring stand (112); the inner ring stand (112) is disposed at a lower end portion of the inner ring body (111) and protrudes radially from an outer wall of the inner ring body (111); and both the middle ring (12) and the outer ring (13) are mounted above the inner ring stand (112). When the described type of mounting sleeve (1) is used to connect a connecting rod and a seat plate (2), the mounting sleeve (1) may abut against a cone column (3) provided on the seat plate (2) by means of the inner ring stand (112). When disassembly is required, an operating tool such as a crowbar may be used to pry the inner ring stand (112) upward so as to directly apply a levering force to the inner ring (11). Therefore, only a small levering force is required to remove the mounting sleeve (1). The removal of the mounting sleeve (1) is easier, and damage to the mounting sleeve (1) during the removal process may be largely avoided.
