Problems solved by technology

[0002] Currently on the market for tripods or selfie sticks or telescopic tubes with similar structures, it is inconvenient to stretch or fold the multi-section tubes on the same leg, and the unlocking and locking between adjacent tubes need to be operated separately, which takes a long time to disassemble. It is long and inconvenient to use; the cross-section of the leg tubes is circular, and the distance between adjacent leg tubes is large, resulting in a larger overall volume of the tripod, taking up a lot of space, and inconvenient to carry; the contact between the bottom end and the ground when it is opened The area is small and the relative structure is not stable enough

Embodiment 1

[0052] Such as figure 1 , 2As shown, a telescopic tube at least includes a tube body three 33, a tube body two 31 sleeved in the tube body three 33, a tube body one 32 sleeved in the tube body two 31, and a tube body three 33 sleeved The joint three 53 outside the lower end, the joint two 52 sleeved on the outside of the lower end of the second pipe body 31, and the telescopic mechanism installed between the second pipe body 31 and the first pipe body 32; The upper end of the mouth 531 and the second joint 52 forms a circle of depressions on the inner surface to form a stepped structure 521. The size and shape of the narrowing portion 531 and the stepped structure 521 are adapted, so that when the third joint 53 and the second joint 52 are mated and connected , the constricted portion 531 of the third joint 53 can be inserted into the stepped structure 521 of the second joint 52 .

[0053] Joint 2 52 and joint 3 53 have the same structure, and they are named based on joints ...

Embodiment 2

[0070] The difference between this embodiment and the first embodiment is that the cross-sections of the first pipe body 32, the second pipe body 31 and the third pipe body 33 are circular structures, such as Figure 27-33 As shown, a telescopic leg tube of a tripod at least includes a tube body three 33, a tube body two 31 sleeved in the tube body three 33, a tube body one 32 sleeved in the tube body two 31, and a tube body one 32 sleeved in the tube body two 31. Joint three 53 outside the lower end of three 33, joint two 52 sleeved outside the lower end of pipe two 31, and a telescopic mechanism installed between pipe two 31 and pipe one 32; the lower end of joint three 53 forms a reduced outer diameter The upper end of joint two 52 forms a circle of depressions on the inner surface to form a stepped structure 521. The size and shape of the necked part 531 and the stepped structure 521 are adapted, so that when joint three 53 and joint two 52 When mating and connecting, the ...

Abstract

The invention discloses a telescopic pipe which at least comprises a second pipe body arranged in a third pipe body in a sleeved mode, a first pipe body arranged in the second pipe body in a sleeved mode, a third joint arranged on the third pipe body in a sleeved mode, a second joint arranged on the second pipe body in a sleeved mode and a telescopic mechanism arranged on the first pipe body; and a necking part is formed on the third joint, the second joint forms a step-shaped structure, the telescopic mechanism can abut against the inner wall of the second pipe body to axially move till part of the telescopic mechanism penetrates through the second pipe body to fall into the step-shaped structure, and when the necking part of the third joint stretches into the step-shaped structure of the second joint, the necking part can extrude the telescopic mechanism to move into the second pipe body. A button on each section of pipe body does not need to be manually pressed to conduct stretching or folding operation, stretching can be achieved only by applying external force in the axial direction, and the telescopic pipe is convenient and easy to operate and labor-saving.

Description

technical field [0001] The invention belongs to the technical field of photographic auxiliary equipment, and in particular relates to a telescopic tube. Background technique [0002] Currently on the market for tripods or selfie sticks or telescopic tubes with similar structures, it is inconvenient to stretch or fold the multi-section tubes on the same leg, and the unlocking and locking between adjacent tubes need to be operated separately, which takes a long time to disassemble. It is long and inconvenient to use; the cross-section of the leg tubes is circular, and the distance between adjacent leg tubes is large, resulting in a larger overall volume of the tripod, taking up a lot of space, and inconvenient to carry; the contact between the bottom end and the ground when it is opened The area is small and the relative structure is not stable enough. Contents of the invention [0003] In order to overcome the deficiencies of the prior art, the present invention provides a...
