Problems solved by technology

[0002] At present, the selfie sticks, light stands, tripods and other telescopic rod structures on the market are relatively complicated. After stretching, there is no simple limit structure, which makes it impossible to bear a large force in the axial direction. If the locking mechanism of the prior art is used, Then, when shrinking, each section of the pipe body needs to be unlocked separately, the operation is not simple enough, and the volume is large, and the manufacturing cost is high

Embodiment 1

[0044] Such as Figure 1-4 As shown, a telescopic structure includes an inner tube 1 , an outer tube 3 coaxially sheathed and connected to the inner tube 1 , a telescopic assembly 4 connected to the upper end of the inner tube 1 , and a driving surface 31 located on the outer tube 3 .

[0045] The telescopic assembly 4 includes an elastic member 41 installed along the radial direction of the inner tube 1, one end abuts against the elastic member 41, and the other end protrudes from the opening 11 on the side wall of the inner tube 1. The inclined surface 421 on the side of the outside, in the present embodiment, the elastic member 41 is a spring; in order to facilitate the installation of the elastic member 41, the upper end of the inner tube 1 (with figure 1The direction in the standard) is equipped with a fixed seat 6, the fixed seat 6 includes a left body and a right body connected by a top ring structure, a mounting groove 61 is formed on the side of the left body, a left ...

Embodiment 2

[0056] A selfie stick, comprising a clamping device 7 for clamping a shooting device, a telescopic rod connected to the clamping device 7 in rotation, and a hand-held part 8; the clamping device 7 includes a clamping arm 71, a rotating shaft parallel to the telescopic rod The connecting arm 72 and the connecting end 73 pivotally connected with the connecting arm 72, the connecting end 73 is connected with one end of the telescopic rod, and the other end of the telescopic rod is connected with the hand-held part 8, which can be installed in the hand-held part 8 and adapted to the shooting equipment The control unit, the control unit is the prior art and will not be described in detail.

[0057] The telescopic rod at least includes a middle pipe 2 , an outer pipe 3 sheathed outside the middle pipe 2 , a telescopic assembly 4 connected to the upper end of the middle pipe 1 , and a driving surface 31 located on the outer pipe 3 .

Abstract

The invention discloses a telescopic structure which comprises an inner pipe, an outer pipe, a telescopic assembly connected with the inner pipe and a driving surface arranged on the outer pipe, wherein the telescopic assembly comprises an elastic piece and a protruding part, one end of the protruding part abuts against the elastic piece, the other end of the protruding part extends out of the side wall of the inner pipe, an inclined surface is formed on the protruding part, the driving surface and the end face of the outer pipe are located at different horizontal heights, when the inner pipe moves towards the outer pipe, the driving surface extrudes the convex part to move inwards along the inclined surface, and then the outer pipe continuously extrudes the convex part along the inclined surface, so that the convex part is propped against the inner wall of the outer pipe to translate, and the inner pipe and the outer pipe are overlapped and shrunk along the axial direction. The invention further discloses a selfie stick, a lamp holder and a photography tripod. The matching structure of the telescopic assembly and joints is simple, and the assembly size is reduced; and the adjacent pipe bodies can contract automatically without independent operation, operation is easy and convenient, and the length control flexibility is high.

Description

technical field [0001] The invention belongs to the technical field of selfie sticks, and in particular relates to a telescopic structure, a selfie stick, a light stand and a photography tripod. Background technique [0002] At present, the selfie sticks, light stands, tripods and other telescopic rod structures on the market are relatively complicated. After stretching, there is no simple limit structure, which makes it impossible to bear a large force in the axial direction. If the locking mechanism of the prior art is used, Then, when shrinking, each segment of the pipe body needs to be unlocked separately, which is not easy to operate, and the volume is large, and the manufacturing cost is high. Contents of the invention [0003] In order to overcome the deficiencies of the prior art, the present invention provides a telescopic structure capable of realizing axial limit and convenient shrinking operation, a selfie stick, a light stand, and a photography tripod. [000...
