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 telescopic tube of the vacuum cleaner of this embodiment is such as figure 1 with figure 2 As shown, one side of the inner tube 1 is formed with a stepped tangential locking groove 2 and the other side is formed with an axial anti-rotation groove 3. The outer tube 4 is sleeved outside the inner tube 1, and is slotted at one end of the locking groove 2 on the inner tube 1, and the locking seat 12 is fixed in the groove. The rear (right) end of the locking seat 12 is hinged with a fan-shaped pendulum block 6 through a pin. A tangential inclined surface is formed on the lower surface of the pendulum block 6, and the inclined surface abuts against the upper end of the locking column 10 flexibly inserted in the locking seat 12.

[0014] In order to facilitate the attachment to the inclined surface, the upper end of the locking column 10 is made with a chamfer that is consistent with the direction of the inclined surface. The lower end of the locking column 10 is made into a...

Embodiment 2

[0021] The basic structure of this embodiment is the same as that of the first embodiment. The difference is that an expansion plate is fixed on the push button 9. The periphery of the 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 vacuum cleaner component, in particular to a structural improvement of a vacuum cleaner telescopic tube adjustment and locking mechanism, and belongs to the technical field of household cleaning facilities. Background technique [0002] Vacuum cleaners are common modern cleaning tools and are widely used in hotels, offices, homes and many other occasions. In order to make the vacuum cleaner more convenient and reliable in use, the applicant of this patent has been committed to the research and improvement of the vacuum cleaner telescopic tube for many years, and proposed improvements to the adjustment and locking structure of the vacuum cleaner telescopic tube from multiple angles, and successively submitted to the Chinese government The Intellectual Property Office has applied for a number of patents. [0003] Among them, the technical solution with the ZL00219979 patent as a typical structure discloses a vacuum cleaner telescopi...
