Abstract
The invention relates to the field of connecting components of video presenters, in particular to a folding-unfolding structure for a video presenter, which mainly comprises an armed lever, a main body and a rotating shaft, wherein the armed lever is connected with the main body through the rotating shaft; a bracket is arranged at one end of the rotating shaft, and an auxiliary bracket is arranged at the other end of the rotating shaft; a one-way bearing and a bearing sleeve are sleeved on the rotating shaft; the one-way bearing is pressed in the bearing sleeve; the bearing sleeve is connected and fixed with the armed lever through screws; and the bracket and the auxiliary bracket are fixedly connected with the main body. The invention has the beneficial effects that the structure of the invention can enable the video presenter to be folded or unfolded conveniently in the using process, larger torsion can be generated by applying proper force so that the armed lever can be unfolded easily, the video presenter can not turn, interfaces can not loose or fall, and the whole working process is relatively stable.
Description
Technical field
The present invention relates generally to the link member field of video showing platform, mainly is a kind of folding-Unclosing structure that is used for video showing platform.
Background technology
Video showing platform uses need open armed lever, and folding armed lever is stored in the dais when depositing.Traditional folding mode, majority are with frictional force control, cause easily when opening because torsion is excessive, cause that exhibition booth integral body stirs, and cause rear port loosening or come off.
Summary of the invention
The present invention will solve the shortcoming of above-mentioned prior art, and folding-Unclosing structure that is used for video showing platform of a kind of easy to operate, working stability is provided.
The present invention solves the technical scheme that its technical problem adopts: this folding-Unclosing structure that is used for video showing platform, mainly comprise armed lever, main body and rotating shaft, be connected by rotating shaft between armed lever and the main body, one end of described rotating shaft is provided with support, the other end is provided with auxiliary stand, is with unilateral bearing and bearing holder (housing, cover) in the rotating shaft, and unilateral bearing is compressed in the bearing holder (housing, cover), bearing holder (housing, cover) is connected and fixed by screw and armed lever, and support is fixedlyed connected with main body with auxiliary stand.
Described support is fixed in the rotating shaft by pad, saddle type bullet pad and nut.
Described auxiliary stand is fixed in the rotating shaft by jump ring.
The effect that the present invention is useful is: structure of the present invention can make folding with convenience in use, just can produce bigger torsion as long as apply suitable dynamics, thereby easily must launch armed lever, can not overturn in the exhibition booth, interface can not become flexible or come off yet, and entire work process is more steady.
Description of drawings
Fig. 1 is an open mode schematic diagram of the present invention;
Fig. 2 is a partial exploded view of the present invention;
Fig. 3 is a partial sectional view of the present invention.
Description of reference numerals: armed lever 1, main body 2, support 3, saddle type bullet pad 4, rotating shaft 5, nut 6, pad 7, screw 8, bearing holder (housing, cover) 9, unilateral bearing 10, auxiliary stand 11, jump ring 12.
The specific embodiment
The invention will be further described below in conjunction with drawings and Examples:
As shown in the figure, this folding-the Unclosing structure that is used for video showing platform, mainly comprise armed lever 1, main body 2 and rotating shaft 5, be connected by rotating shaft 5 between armed lever 1 and the main body 2, one end of described rotating shaft 5 is provided with support 3, support 3 is by pad 7, saddle type bullet pad 4 and nut 6 are fixed in the rotating shaft 5, the other end is provided with auxiliary stand 11, auxiliary stand 11 is fixed in the rotating shaft 5 by jump ring 12, jump ring 12 is used for axial fixing, and is with unilateral bearing 10 and bearing holder (housing, cover) 9 in the rotating shaft 5, and unilateral bearing 10 is compressed in the bearing holder (housing, cover) 9, bearing holder (housing, cover) 9 is connected and fixed by screw 8 and armed lever 1, and support 3 is fixedlyed connected with main body 2 with auxiliary stand 11.
When armed lever 1 is opened by folded state such as Fig. 1, because unilateral bearing 10 can freely rotate in the direction of opening, armed lever 1 is with regard to tightly 5 rotations around the shaft like this, and the very little torsion of usefulness just can be opened armed lever 1.When armed lever 1 by open mode during to closure state, at this moment unilateral bearing 10 cannot rotate, armed lever 1 has just driven rotating shaft 5 rotations with unilateral bearing 10 assemblies like this, because rotating shaft 5 is to be connected support 3 by pad 7, saddle type bullet pad 4 and nut 6 certain torsion pretension is arranged, folding like this armed lever 1 just needs corresponding torsion, and this torsion also is that armed lever 1 is stable when keeping armed lever 1 duty simultaneously.So just realized, opened low torsion, the process of folding high torsion.
In addition to the implementation, all employings are equal to the technical scheme of replacement or equivalent transformation formation, all drop on the protection domain of requirement of the present invention.
