Problems solved by technology

[0006] For this reason, the technical problem to be solved by the present invention is that although the leg tube structure of the prior art tripod can be quickly opened or folded, it is not convenient to realize the adjustment of any length within the length range of the leg tube. Adjustable telescopic tube structure for any length within the length range

Embodiment 1

[0041] like Figure 1-5 As shown, a telescopic tube structure of this embodiment includes an outer tube 1, an inner tube 2 that can be extended or retracted and sleeved in the outer tube, and the outer tube 1, the inner tube 2. An integrated locking structure. At least one through hole 21 is formed on the side wall of the inner tube 2 inserted into the end of the outer tube 1. The locking structure includes a spring 3, and the number is the same as that of the through hole 2. A consistent top block 4, wherein the tail 42 of the top block 4 is inserted into the through hole 21, the head 41 protrudes out of the through hole 21, and the biasing force of the spring 3 acts on the top block 4 , make the head 41 of the top block 4 press against the inner wall of the outer tube 1, and connect the inner tube 2 and the outer tube 1 together.

[0042] Because the locking structure is designed to include the spring 3 and the jack block 4 whose number is consistent with the through hole 2...

Embodiment 2

[0058] like Figure 8 and 9 As shown, as a modification of Embodiment 1, the biasing member 3 is a torsion spring, the torsion spring is fixed on the inner tube 2 through a connection structure, and the two elastic legs of the torsion spring respectively act on the top block 4 on. The connection structure may be a pin shaft.

Abstract

The invention discloses a telescopic tube structure which comprises a spring and jacking blocks equal to through holes in number. The tails of the jacking blocks are inserted into the through holes, and the heads stretch out of the through holes, so that the jacking blocks are clamped between an inner pipe and an outer pipe. When the inner pipe is pulled, the jacking blocks are driven by the inner pipe to slide up and down along the outer pipe. The bias pressure of the spring acts on the jacking blocks, so that the heads of the jacking blocks abut against the inner wall of the outer pipe, and the inner pipe and the outer pipe are integrally connected. The inner pipe is pulled to stop at any position of the outer pipe, the bias pressure of the spring acts on the jacking blocks to generate balanced and stable damping, and a foot pipe can bear certain weight, such as that of a camera, so that adjustment by any length within in the length range of the camera foot pipe can be achieved.

Description

technical field [0001] The invention relates to a telescopic tube structure, in particular to a telescopic leg tube structure on photographic and video equipment. Background technique [0002] In the prior art, the leg tubes of the tripods for photography and videography are set to be telescopic, and usually include an inner tube, an outer tube, and a locking structure that locks the inner tube and the outer tube together. When in use, it is usually necessary to lock the lock on the locking structure. The tightening ring can be rotated multiple times in the tightening direction or loosening direction to lock or adjust the leg tube. The leg tube of this structure can usually withstand a relatively high-quality camera, but it has a large mass and is time-consuming to operate. , and very inconvenient. [0003] With the development of photographic and video equipment, small and light photographic and video equipment is more popular among photographers. Since the camera can be m...
