The utility model aims at the above problem, provide a rotatory flexible removable stand, it can reduce the car cataract and hinder and effectively improve dismouting efficiency.

In order to realize the above purpose, the utility model adopts the technical scheme that: a rotary telescopic detachable upright post is characterized in that the top end of the upright post is arranged in a hexagonal groove formed in an upper support; the novel support is characterized in that a sleeve is sleeved in the stand column, the small end of the sleeve is sleeved in the stand column, an inner hole of the large end of the sleeve is a threaded hole, a screw rod is matched with the inner thread of the threaded hole of the sleeve in a matched mode, the bottom end of the screw rod is arranged in a hexagonal groove formed in the lower support, the top end of the stand column and the low end of the screw rod are both arranged in a hexagonal prism shape, and the hexagon of the hexagonal prism is matched with the corresponding hexagonal groove in the upper support or the lower support.

Further, the total height of the upright post, the sleeve and the screw rod when the upright post, the sleeve and the screw rod are completely contracted is smaller than the height from the bottom surface of the polygonal groove of the upper support to the bottom surface of the polygonal groove of the lower support.

Furthermore, the small end of the sleeve is limited to move in the upright post through a first limiting pin.

Furthermore, the threaded end of the screw is limited to move in the sleeve through a second limiting pin.

Further, the length of the threaded fit between the screw and the sleeve is less than the total length of the screw.

Furthermore, a force application hole is formed in the small end of the sleeve.

The utility model has the advantages that:

1. under the condition of high integration of equipment in a special vehicle, when the equipment in the vehicle is disassembled and assembled, the manual rotation, the extension and disassembly type upright posts can reduce the trouble of the vehicle and effectively improve the disassembling and assembling efficiency.

2. The utility model discloses the application of stand can improve the feasibility of in-car equipment arrangement, is favorable to improving man-machine ring performance.

3. The utility model discloses have locking anti loosening structure, prevent that the stand is not hard up droing at the in-process of traveling, the reliability is high.

4. The utility model discloses it utilizes jack principle screw thread rotation flexible to be equipped with the power hole, and is easy and simple to handle laborsaving.

Detailed Description

In order to make the technical solution of the present invention better understood, the present invention is described in detail below with reference to the accompanying drawings, and the description of the present invention is only exemplary and explanatory, and should not be construed as limiting the scope of the present invention.

As shown in fig. 1-2, the specific structure of the present invention is: in order to realize the above purpose, the utility model adopts the technical scheme that: the top end of the upright post 2 is arranged in a hexagonal groove formed in the upper support 1; the novel support is characterized in that a sleeve 3 is sleeved in the upright post 2, the small end of the sleeve 3 is sleeved in the upright post 2, an inner hole of the large end of the sleeve 3 is a threaded hole, a screw rod 4 is matched with the inner thread of the threaded hole of the sleeve 3, the bottom end of the screw rod 4 is arranged in a hexagonal groove formed in the lower support 5, the top end of the upright post 2 and the low end of the screw rod 4 are both arranged in hexagonal prisms, and hexagons of the hexagonal prisms are matched with corresponding hexagonal grooves formed in the upper support 1 or the lower support 5.

Preferably, the total height of the upright 2, the sleeve 3 and the screw rod 4 when the upright is completely contracted is smaller than the height from the bottom surface of the polygonal groove of the upper support 1 to the bottom surface of the polygonal groove of the lower support 5, so that the upright can be conveniently and quickly disassembled.

Preferably, the small end of the sleeve 3 is limited in its movement in the column 2 by a first limit pin 6.

Preferably, the threaded end of the screw 4 is limited in its movement within the sleeve 3 by a second limit pin 7.

Preferably, the length of the screw rod 4 in threaded fit with the sleeve 3 is less than the total length of the screw rod 4, so that the screw rod can be screwed out quickly.

Preferably, the small end of the sleeve 3 is provided with a force applying hole 8, so that the sleeve is convenient to screw.

When the utility model is used, firstly, the upper support 1 and the lower support 5 are fixed at the required positions of the supporting upright; then sleeve 3 is sleeved on the lower part of upright 2, the thread end of screw rod 4 is screwed into the thread of sleeve 3, the lower end of screw rod 4 is placed in the polygonal hole of lower support 5, so that screw rod 4 can not rotate, then the external rod is inserted into force-applying hole 8, upright 2 is held by hand and sleeve 3 is rotated, upright 1 is made to rise, the upper end of upright 1 is inserted into the polygonal hole of support 1, sleeve 3 is continuously rotated, when upright 2 is completely supported, first bolt 6 and second bolt 7 are installed, and installation is completed.
