Abstract

The utility model relates to tripod foot tubes. The tripod foot tubes comprise a small foot tube and a big foot tube, wherein a locking component is arranged between the small foot tube and the big foot tube, is sleeved on the small foot tube, and slides in the axial direction, the upper end of the small foot tube is fixedly provided with a slide stopping barrel, the small foot tube and the slide stopping barrel are jointly inserted into the big foot tube and can axially slide in the big foot tube, three grooves are arranged on the outer circumference of the slide stopping barrel along the axial direction, and three rotation prevention protruding ribs corresponding to the positions of the three grooves are arranged in the big foot tube along the axial direction, and arranged in the three grooves in a sliding mode. The tripod foot tubes are simple in structure, and torsion resistance ability between the foot tubes is improved.

Description

Tripod scaffold tube

Technical field

The utility model relates to a kind of telescopic support device, particularly a kind of tripod scaffold tube.

Background technique

At present, the photographic tripod of selling on the market all is to be formed by connecting by locking member by telescopic more piece pin pipe basically, the pin pipe that any two joints link to each other on it can be divided into a bound feet pipe and a big foot pipe, bound feet pipe upper end is installed with slip limiting plate, form single groove or double flute between two slip limiting plates, the on-slip cylinder of bound feet pipe and upper end thereof inserts together in the big foot pipe and can slide at the big foot inner axial tube, and the big foot inner tube wall is generally established wall scroll anti-rotation convex tendon and placed one of above-mentioned single groove or double flute to rotate in the big foot pipe to prevent the bound feet pipe.And locking member generally all locks circle by screwed pipe joint and screw thread chuck and slip limiting plate is realized, employing is threaded and must causes bound feet pipe and big foot pipe to relatively rotate in the locking process, wall scroll anti-rotation convex tendon places the structure of single groove so that the anti-twisting property between big foot pipe and the bound feet pipe is poor, for ordinary consumer, if because of carelessness slip limiting plate is turned round bad then be difficult to its recovery, therefore bring many worries and inconvenience to the user.The applicant improved said structure through the long-term time, and the present invention makes under such background.

The model utility content

In order to solve above-mentioned technical problem, it is a kind of simple in structure that the utility model provides, and improved the tripod scaffold tube of the anti-twisting property between pin pipe and the pin pipe.

The technological scheme that its technical problem that solves the utility model adopts is:

Tripod scaffold tube, comprise bound feet pipe and big foot pipe, it is characterized in that: bound feet pipe upper end is installed with the on-slip cylinder, the on-slip cylinder of bound feet pipe and upper end thereof inserts together in the big foot pipe and can slide at the big foot inner axial tube, on-slip cylinder excircle is provided with three grooves vertically, the big foot inner tube wall is provided with three anti-rotation convex tendons vertically corresponding to three groove location, and three anti-rotation convex tendons slide and place in three grooves.

Tripod scaffold tube is characterized in that: be provided with locking member between described bound feet pipe and the big foot pipe, endwisely slip on the locking member suit bound feet pipe as mentioned above.

The beneficial effects of the utility model are: bound feet pipe upper end is installed with the on-slip cylinder, the on-slip cylinder of bound feet pipe and upper end thereof inserts together in the big foot pipe and can slide at the big foot inner axial tube, on-slip cylinder excircle is provided with three grooves vertically, the big foot inner tube wall is provided with three anti-rotation convex tendons vertically corresponding to three groove location, article three, the anti-rotation convex tendon slides and places in three grooves, with respect to prior art, this structure has improved the anti-twisting property between big foot pipe and the bound feet pipe.

Embodiment

By Fig. 1 to Fig. 5 as can be known, tripod scaffold tube comprises bound feet pipe 1 and big foot pipe 2, is provided with locking member 3 between bound feet pipe 1 and the big foot pipe 2, endwisely slips (as shown in Figure 6) on the locking member 3 suit bound feet pipes 1; There is hole clipping bound feet pipe 1 upper end, bound feet pipe 1 is connected to on-slip cylinder 4 by the hole clipping fixed card on rising, the on-slip cylinder 4 of bound feet pipe 1 and upper end thereof inserts together in the big foot pipe 2 and can endwisely slip in big foot pipe 2, on-slip cylinder 4 excircles are provided with three grooves 41 vertically, big foot pipe 2 inwalls are provided with three anti-rotation convex tendons 21 vertically corresponding to three groove 41 positions, article three, anti-rotation convex tendon 21 slides and places in three grooves 41, and the slide structure that places three grooves 41 of three anti-rotation convex tendons 21 has improved anti-twisting property between big foot pipe 2 and the bound feet pipe 1 greatly.

In the utility model, locking member 3 can adopt various structures, and the utility model is not limited to the locking member of any structure.For example locking member 3 can be inside and outside internal lock collar and the chuck that arranges, the internal lock collar is set with successively on the bound feet pipe with chuck and can axially slides by relative bound feet pipe, chuck is threaded with big foot pipe lower end, when chuck advances to the big foot pipe, the big foot pipe oppositely pushes up the male cone (strobilus masculinus) of pressing the internal lock collar, the internal lock collar compresses the bound feet pipe, realizes the mutual locking of big foot pipe, bound feet pipe and chuck.

Claims

1. tripod scaffold tube, comprise bound feet pipe and big foot pipe, it is characterized in that: described bound feet pipe upper end is installed with the on-slip cylinder, the on-slip cylinder of bound feet pipe and upper end thereof inserts together in the big foot pipe and can slide at the big foot inner axial tube, on-slip cylinder excircle is provided with three grooves vertically, described big foot inner tube wall is provided with three anti-rotation convex tendons vertically corresponding to three groove location, and three anti-rotation convex tendons slide and place in three grooves.
