Embodiment Construction

[0014] Referring to accompanying drawings 1 to 7, a suction pipe of a telescopic vacuum cleaner includes an outer pipe 2, an inner pipe 1 with a stop bar 3 extending in the axial direction, and at least one stop groove 4 matching the stop bar 3 Functional locking piece 16, the inner tube 1 is slidably inserted in the outer tube 2, a stop slider 11 is arranged between the outer tube 2 and the inner tube 1, and the stop slider 11 is connected with the inner tube 1. The outer surfaces of the inner tube 1 are in contact with each other, and the locking member 16 is arranged on the stop slider 11 . The outer tube 2 is slidably sleeved with a control sleeve 5, and the control sleeve 5 has at least one free space 22 for the displacement of the locking member 16, and the locking member 16 can break away from the stop groove 4 and Located in free space 22 .

[0015] Referring to accompanying drawings 2, 4-7, the control sleeve 5 is provided with a compression ring 12, and the control ...

Abstract

A telescopic sucking pipe for cleaner is composed of an external pipe, an internal pipe with stop slot, a stopping slide block arranged between internal and external pipes, a locking part on said stopping slide block and matched with said stop slot, a manipulating sleeve pipe for external pipe and a deformable elastic clamping ring between internal and external pipes for improving the locking force between them.

Description

technical field [0001] The invention relates to a retractable vacuum cleaner suction pipe. Background technique [0002] The existing retractable vacuum cleaner suction pipe includes an outer tube, an inner tube with a stop bar extending axially, and a locking piece that matches the stop groove of the stop bar. The locking piece is arranged on the stop slider, and the stop The slider is mounted on the outer tube and partly slidably socketed with the inner tube, and the stop slider is surrounded by an operating sleeve to axially drive the stop slider, so that the locking piece cooperates with the stop groove to realize Retractable vacuum cleaner suction pipe. However, when the straw is subjected to a large axial impact force, even if the outer tube and the inner tube have been locked, the axial movement of the stop slider will still cause the locking between the outer tube and the inner tube The mechanism is damaged, and its reliability in use is l...
