Abstract
The utility model discloses a tripod foot pipe, including little foot pipe and big foot pipe, little foot pipe upper end fixed mounting has the antiskid section of thick bamboo, and it is intraductal that the antiskid section of thick bamboo of little foot pipe and upper end inserts big foot together, and the antiskid section of thick bamboo outer circumference is equipped with five recesses along the axial, and big foot inside pipe wall is provided with five protruding muscle of preventing changeing corresponding to five groove position along the axial, and five are prevented changeing protruding muscle and are slided and arrange five recesses in. The anti-rotation convex ribs are arranged in the five grooves, so that the circumferential torsion resistance can be effectively improved. The utility model discloses simple structure has improved antitorque ability between foot pipe and the foot pipe.
Description
Technical field
The utility model relates to telescopic support device, is specifically related to 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 model utility content
The purpose of this utility model is to provide a kind of tripod scaffold tube, and it is simple in structure, has improved the anti-twisting property between pin pipe and the pin pipe.
For achieving the above object, the technical solution of the utility model is a kind of tripod scaffold tube of design, comprise bound feet pipe and big foot pipe, 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 in the big foot pipe together, on-slip cylinder excircle is provided with five grooves vertically, and the big foot inner tube wall is provided with five anti-rotation convex tendons vertically corresponding to five groove location, and five anti-rotation convex tendons slide and place in five grooves.
Preferably, described anti-rotation convex tendon is provided with the rubber salient point at the surface of contact of itself and groove.
The anti-rotation convex tendon places in five grooves, can the circumferential anti-twisting property of Effective Raise.
Advantage of the present utility model and beneficial effect are: a kind of tripod scaffold tube is provided, and it is simple in structure, has improved the anti-twisting property between pin pipe and the pin pipe.
Description of drawings
Fig. 1 is schematic representation of the present utility model.
Embodiment
Below in conjunction with drawings and Examples, embodiment of the present utility model is further described.Following examples only are used for the technical solution of the utility model more clearly is described, and can not limit protection domain of the present utility model with this.
The technological scheme of the utility model implementation is:
A kind of tripod scaffold tube, comprise bound feet pipe 1 and big foot pipe 2, bound feet pipe 1 upper end is installed with on-slip cylinder 3, the on-slip cylinder 3 of bound feet pipe 1 and upper end thereof inserts in the big foot pipe 2 together, on-slip cylinder 3 excircles are provided with five grooves 4 vertically, big foot pipe 2 inwalls are provided with vertically 5 slips of 5, five anti-rotation convex tendons of five anti-rotation convex tendons corresponding to five groove 4 positions and place in five grooves 4.Described anti-rotation convex tendon 5 is provided with the rubber salient point at the surface of contact of itself and groove 4.
The above only is preferred implementation of the present utility model; should be understood that; for those skilled in the art; under the prerequisite that does not break away from the utility model know-why; can also make some improvements and modifications, these improvements and modifications also should be considered as protection domain of the present utility model.
