Abstract

The utility model discloses a rotary-clamp-type tripod bracket fixing device which comprises an inner pipe, an outer pipe, a rotary clamp, a first gasket and a second gasket, wherein the first gasket and the second gasket are matched with the outer wall of the inner pipe; a fixed button is arranged on the part, close to the end part, of the outer wall of the inner pipe; a first limiting hole and a second limiting hole which are matched with the fixed button are arranged on the first gasket and the pipe wall of the outer pipe respectively; and the rotary clamp wraps the outer wall of the outer pipe. The device disclosed by the utility model has a simple structure and is convenient to operate; through the rotary clamp, the inner pipe and the outer pipe can deform, and the simultaneous opposite acting forces of the inner and outer pipes at the rotary clamp are combined with the friction force between the first gasket and the second gasket so as to effectively achieve the aim of freely stretching and withdrawing and fixing the inner pipe. Accessories are reduced, and the portability and practicability are improved.

Description

Swivel bayonet type tripod bracket fixing device

Technical field

The utility model relates to the tripod bracket component, relates in particular to a kind of swivel bayonet type tripod bracket fixing device.

Background technique

In the prior art, the technique for fixing of tripod support has a lot of solutions, and purpose is the leg pipe that extends out is fixed, and in limited range, freely raises or reduces and use height.Common means of fixation is pulled button-type, the screw thread lock, but can not satisfy more needs of people.

Summary of the invention

To the problem that above-mentioned existing technology exists, the utility model provides a kind of swivel bayonet type tripod bracket fixing device.

To achieve these goals; The technological scheme that the utility model adopts is: a kind of swivel bayonet type tripod bracket fixing device; Pipe and outer tube in comprising, also comprise revolve card, with first pad and second pad that the outer wall of interior pipe is complementary, the outer wall of interior pipe locates to be provided with fixing button near the end; Be respectively equipped with first spacing hole and second spacing hole that are complementary with fixing button on the tube wall of first pad and outer tube, revolve the outer wall that card is coated on outer tube.

As preferably, fixing button, first spacing hole is identical with second spacing hole shape size and the position is corresponding.

As preferably, first pad and second pad are provided with integrated with it anticreep card near the intrados of end.

Compared with prior art; The advantage of the utility model is: simple in structure, easy-to-operat is through revolving the design of card; Pipe produces deformation with outer tube in making; Revolve card place inner and outer pipes active force in opposite directions simultaneously,, freely stretch and fixing interior purpose of managing thereby reach effectively in conjunction with the frictional force of first pad and second pad.Reduce accessory and improve portability and practicability.

Embodiment

To combine accompanying drawing that the utility model is described further below.

A kind of mode of execution as the utility model; Consult Fig. 1, Fig. 2, Fig. 3, Fig. 4 and Fig. 5; Pipe 1 and outer tube 2 in the utility model comprises, also comprise revolve card 6, with first pad 31 and second pad 32 that the outer wall of interior pipe 1 is complementary, the outer wall of interior pipe 1 locates to be provided with fixing button 4 near the end; Be respectively equipped with first spacing hole 51 and second spacing hole 52 that is complementary with fixing button 4 on the tube wall of first pad 31 and outer tube 2, revolve the outer wall that card 6 is coated on outer tube 2.Fixing button 4, first spacing hole 51 are identical with second spacing hole, 52 shapes size and the position is corresponding.First pad 31 and second pad 32 are provided with integrated with it anticreep card 33 near the intrados of end.

Simple in structure, easy-to-operat is when people use; Through revolving the design of card 6, pipe 1 produces deformation with outer tube 2 in making, and revolves card 2 whiles of 6 place's inner and outer pipes active force in opposite directions; In conjunction with the frictional force of first pad 31 and second pad 32, thereby reach the purpose of freely stretching and fixing interior pipe 1 effectively.Reduce accessory and improve portability and practicability.

To the above-mentioned explanation of the disclosed embodiments, make related domain professional and technical personnel can realize or use the utility model.Multiple modification to these embodiments will be conspicuous concerning those skilled in the art, and defined General Principle can realize under the situation in spirit that does not break away from the utility model or the scope in other embodiments among this paper.Therefore, the utility model will can not be limited to these embodiments shown in this paper, but will accord with principle disclosed herein and features of novelty the wideest corresponding to scope.
