Embodiment Construction

[0016] Such as figure 1 , figure 2 and image 3 As shown, a telescopic tube locking mechanism includes an outer tube 1 and an inner tube 3, and also includes an outer tube wall boss 11 and an intermediate layer 2. The outer tube wall boss 11 is arranged on the inner wall of the outer tube 1, and the middle layer 2 It is arranged between the outer pipe 1 and the inner pipe 3, the inner wall of the middle layer 2 is connected with the outer wall of the inner pipe 3 by threads, the middle layer 2 is an unclosed circular arc, the two ends of the middle layer 2 are in contact with the boss 11 of the outer pipe wall, and the middle Layer 2 includes a middle layer thick-walled part 21 and a middle layer thin-walled part 22. From the middle layer thick-walled part 21 to the middle layer thin-walled part 22, the wall thickness of the middle layer 2 gradually becomes thinner, and the inner tube 3 includes an inner tube wall thickness The part 31 and the inner tube thin-walled par...

Abstract

A telescopic pipe locking method comprises the following steps: arranging two interlayers between an inner pipe and an outer pipe of the telescopic pipe, wherein the interlayers cannot rotate but can move up and down along with the inner pipe; each interlayer comprises a thick-walled part and a thin-walled part; rotating the inner pipe, wherein the telescopic pipe is in a locked state when the thick-walled part of the inner pipe and the thick-walled parts of the interlayers are in sufficient contact with each other; rotating the inner pipe, wherein the telescopic pipe is in an unlocked state when the thick-walled part of the inner pipe is completely separated from the thick-walled parts of the interlayers. The invention further provides a telescopic pipe locking mechanism which comprises the inner pipe and the outer pipe, and further comprises outer pipe wall lug bosses and the interlayers, wherein the outer pipe wall lug bosses are arranged on the inner wall of the inner pipe; the interlayers are arranged between the outer pipe and the inner pipe; the inner walls of the interlayers are in threaded connection with the outer wall of the inner pipe. The telescopic pipe locking mechanism provided by the invention has the advantages that the locking and unlocking are relatively smooth; the locking state is relative stable.

Description

technical field [0001] The invention specifically relates to a locking method and a locking mechanism for a telescopic tube. Background technique [0002] Telescopic tubes are common objects in production and life, such as batons, clothes pole tripods and so on. The existing telescopic tube is inconvenient to unlock, the operation of unlocking and locking is not smooth enough, and the locking is not stable enough. When the multi-section telescopic tubes are unlocked or locked at the same time, the operation is inconvenient. Contents of the invention [0003] In order to solve the above technical problems, the present invention proposes a telescopic tube locking method and a locking mechanism, the locking and unlocking operations are relatively smooth, and the locking is relatively stable. Its technical solution is: [0004] A telescopic tube locking method, in which an intermediate layer is arranged between the inner tube and the outer tube of the telescopic ...
