Problems solved by technology

[0003] In order to facilitate the adjustment of the telescopic length of the telescopic tube and ensure that the telescopic tube will not automatically shrink during the shooting process, the telescopic tubes used in the field of photographic equipment on the market are generally equipped with a locking mechanism for adjusting the telescopic length of the telescopic tube. Although some mechanisms can quickly adjust the telescopic length of the telescopic tube, the structure is very complicated and the production cost is high; although other locking mechanisms with simple structures are low in production cost, they are not firm when locking the telescopic length of the telescopic tube. , the telescopic length of the telescopic tube is prone to change and affect the shooting of photographic equipment

Embodiment Construction

[0033] refer to figure 1 Referring to Fig. 6, the first preferred embodiment of the present invention, a locking structure applied to telescopic tubes, includes:

[0034] A telescopic tube 10, the telescopic tube 10 is composed of one or more inner tubes 11 and one or more outer tubes 12 which are movably socketed with each other. The pipe fitting is the outer pipe 12, and the inner pipe fitting is the inner pipe 11. The number of the above-mentioned inner pipe 11 and outer pipe 12 is not limited, and may be determined according to actual needs, but at least one inner pipe 11 and one outer pipe are included. tube 12;

[0035] A locking mechanism, the locking mechanism includes a fixing part 21 and a tensioning part 22, the fixing part 21 is fixedly arranged on one end of the outer tube 12 and has an inner opening for the inner tube 11 to pass through and inserted into the through hole inside the outer tube 12. In the present invention, the above-mentioned fixing member 21 an...

Abstract

The invention discloses a locking structure applied to an extension pipe. The locking structure comprises the extension pipe, a locking mechanism including a fixed piece and an expansion piece, and an unlocking mechanism for pushing the extension piece to retreat from the middle of an inner pipe and the fixed piece so as to remove expansion locking between the inner pipe and the fixed piece. As the expansion piece movably sleeved on the outer peripheral wall of the inner pipe is inserted between the inner pipe and the fixed piece for expansion locking of the inner pipe and the fixed piece, the inner pipe and an outer pipe are effectively locked, and the total length of the extension pipe is invariable; when the total length of the extension pipe needs to be adjusted, the unlocking mechanism can push the expansion piece to retreat from the middle of the inner pipe and the fixed piece so as to remove expansion locking between the inner pipe and the fixed piece; and at this time, users can randomly adjust the total length of the extension pipe.

Description

technical field [0001] The invention relates to the field of photographic equipment, in particular to a locking structure applied to telescopic tubes. Background technique [0002] As we all know, the telescopic tube can be extended to support the photographic equipment for shooting, and can be shortened to reduce the volume of the photographic equipment for transportation. Therefore, the telescopic tube is widely used as a support rod for photographic equipment such as selfie sticks and tripods. [0003] In order to facilitate the adjustment of the telescopic length of the telescopic tube and ensure that the telescopic tube will not automatically shrink during the shooting process, the telescopic tubes used in the field of photographic equipment on the market are generally equipped with a locking mechanism for adjusting the telescopic length of the telescopic tube. Although some mechanisms can quickly adjust the telescopic length of the telescopic tube, the structure is ver...
