Embodiment Construction

[0017] In order to facilitate the understanding of those skilled in the art, the structural principle of the present invention will be further described in detail below in conjunction with specific embodiments and accompanying drawings:

[0018] see Figure 1~3 , a telescopic sleeve, mainly composed of an outer tube 2, an inner tube 1 partially sleeved in the outer tube, and an adjustment piece sleeved at the junction of the outer tube and the inner tube. Slightly rotating the adjustment part can quickly make the inner tube 1 protrude from the outer tube 2 or retract into the outer tube, and correspondingly make the entire tube lengthen or shorten. Turning the jacket overcomes the spring force to make the inner tube stretch. The new position is quickly positioned due to the restoring force of the adjusting spring. The telescopic pipe can be used as a telescopic support frame for musical instruments, and the telescopic support frame is convenient for storage and transportation...

Abstract

The invention provides a telescopic sleeve and relates to the technical field of tubing connection. The telescopic sleeve comprises an outer tube and an inner tube partially sleeved in the outer tube; and a connecting part between the outer tube and the inner tube is sleeved with an adjusting piece for locking the inner tube in the outer tube. The adjusting piece comprises an inner sleeve fixed with the wall of the outer wall; the outside of the inner sleeve is sleeved with an outer sleeve which can rotate relative to the inner sleeve; and a spring for enclasping the inner tube is arranged and positioned between the top of the inner sleeve and the inner wall of the outer sleeve. The inner tube can rapidly extend out from the outer tube or draw back from the outer tube through rotating the adjusting piece; and owning to the elastic function of the spring in the adjusting piece, the new position of the tubing after stretching can also be rapidly positioned. The adjusting mode can conveniently and rapidly make the tubing flexing; the telescopic sleeve has a simple and durable structure; and the concealed type formation is also convenient for the whole shape design of the telescopic tubing and simultaneously enhances the whole molding effect and value of a product which adopts the telescopic tubing.

Description

technical field [0001] The invention relates to the technical field of telescopic pipe connection. Background technique [0002] All kinds of pipes have the problem of connecting pipe ends to each other during use. In order to facilitate storage, many pipe brackets used in lighting, furniture, musical instruments and other product fields are made of retractable sleeves. [0003] At present, in the retractable sleeve products, the elongation or shortening of the inner tube in the outer tube mainly adopts the traditional thread fit method and snap fit method. The traditional thread fit method requires long-term rotation at a large angle when the inner tube is extended or shortened relative to the outer tube. This method is slow and inconvenient; while in the snap fit method, the inner tube outer wall needs to The joint with the inner wall of the outer tube is provided with buckle joints, which is inconvenient to process and also inconvenient to adjust the telescopic distance...
