Problems solved by technology

This kind of vacuum cleaner telescopic tube has the advantages of convenient assembly and easy tube length adjustment, but because the locking relies on the elastic piece to snap into the semicircular groove of the inner tube, it may still slip when subjected to a large force, especially when the parts are worn. This phenomenon is more likely to occur after
Although several improvements since then have made beneficial progress, the locking reliability of the telescopic tube has been continuously improved, but when the vacuum cleaner encounters a large impact force during the pushing operation, slippage may still occur, and there are still problems. safety hazard

Embodiment 1

[0013] The telescoping tube of the vacuum cleaner of the present embodiment is as figure 1 and figure 2 As shown, one side of the inner tube 1 is formed with stepped tangential locking grooves 2, and the other side is formed with axial anti-rotation grooves 3. The outer tube 4 is sleeved outside the inner tube 1, and one end of the locking groove 2 on the inner tube 1 is grooved, and the locking seat 12 is fixed in the groove. The rear (right) end of this locking seat 12 is hinged fan-shaped pendulum block 6 by pins. The lower side of the pendulum block 6 is formed with a tangential slope, which abuts against the upper end of the locking post 10 inserted in the locking seat 12 .

[0014] In order to facilitate fitting with the inclined surface, the upper end of the locking post 10 is formed with chamfers consistent with the direction of the inclined surface. The lower end of the locking column 10 is made into a circular arc end, which can extend out of the locking seat 12 ...

Embodiment 2

[0021] The basic structure of this embodiment is the same as that of Embodiment 1, the difference is that an expansion plate is fixed on the push button 9, the periphery of this expansion plate falls in the shallow pool of the cover 13, and the upper surface is flush with the upper surface of the cover 13. In this way, the fixing screws on the cover plate 11 are hidden, and the appearance is more neat and beautiful.

Abstract

A regulating-locking mechanism for the telescopic pipe of suction cleaner is composed of internal pipe, external pipe with a slotted end for mounting a lock seat to it, push-button mounted in the axial translation mechanism on lock seat, and a swinging block hinged to said lock seat. Its feature is that the shape of said swinging block is designed to form a 3D crossed self-locking structure.

Description

technical field [0001] The invention relates to a part of a vacuum cleaner, in particular to a structural improvement of an adjusting and locking mechanism for a telescoping tube of a vacuum cleaner, and belongs to the technical field of household cleaning facilities. Background technique [0002] Vacuum cleaners are modern common cleaning tools, widely used in many occasions such as hotels, offices and families. In order to make the vacuum cleaner more convenient and reliable in use, the applicant of this patent has been devoting himself to the research and improvement of the telescopic tube of the vacuum cleaner for many years, proposed an improvement plan for the adjustment and locking structure of the telescopic tube of the vacuum cleaner from various angles, and successively submitted to the Chinese state The Intellectual Property Office has applied for a number of patents. [0003] Among them, the technical scheme of ZL00219979 patent with a typical structure disclose...
