Abstract
The invention relates to an automatic positioning rotating shaft, which comprises a shell, a rotating shaft mechanism and a clamping plate mechanism, wherein the rotating shaft mechanism comprises a rotating shaft, a roller and a rotating arm; the rotating shaft rotates and is fixed between two side plates in the shell; one end of the rotating shaft is extended out of the side plates of the shell; the rotating arm is fixed at one end, extended out of the shell, of the rotating shaft; the clamping plate mechanism comprises two elastic clamping plates and four fixed legs; the fixed legs are symmetrically fixed on the two sides of the rotating shaft in a way that every two legs form a group; one end of each elastic clamping plate is fixed on the two legs of one fixed leg group, while the other end is arranged between the two legs of the other fixed leg group; and the two elastic clamping plates clamp the roller. The automatic positioning rotating shaft has the characteristics of simple structure, convenient use, easy production and wide use, and can be used for devices, such as free doors, revolving doors, revolving windows and the like.
Description
Technical field
The present invention relates to automatic positioning rotating shaft, particularly a kind of automatic positioning rotating shaft that can be used for free door, revolving door, pivoted window etc.
Background technology
Door is mounted in the device of the access energy switch of building, and the linkage of door leaf and doorframe has varied.For example vertical hinged door can adopt hinge to connect, and free door can adopt floor spring to connect (floor spring have close a function automatically), and revolving door can adopt electric rotation shaft to connect or the like, and these devices also can be referred to as door-hinge.
Summary of the invention
The object of the present invention is to provide a kind of simple in structurely, easy to use, the automatic positioning rotating shaft that is easy to produce can be used for devices such as free door, revolving door, pivoted window.
Technical scheme of the present invention is achieved in that a kind of automatic positioning rotating shaft, includes housing, rotating shaft mechanism and clamping plate mechanism;
Described rotating shaft mechanism comprises rotating shaft, roller and cursor; Described rotating shaft rotational fixation between the biside plate up and down in housing, an end of rotating shaft stretches out the housing side plate; Described roller is four, and two are one group and are fixed on the both sides of described rotating shaft in the housing by the support symmetry, and the center on line of two groups of rollers is parallel to each other and equal in length; Described cursor is fixed on described rotating shaft and stretches out on the end of housing.
Described rotating shaft and described support are connected as a single entity.
Described clamping plate mechanism comprises two Elastic clamping plates and four fixed legs, and two fixed legs are that one group of symmetry is installed in described rotating shaft both sides, and between the biside plate, the center on line of two groups of fixed legs is parallel to each other and equal in length up and down; One end of described two Elastic clamping plates is fixed on two posts of one group of fixed leg, and the other end is arranged between two posts of another group fixed leg, and described two Elastic clamping plates are clamped described roller.
The present invention is compared with prior art:
1. this automatic positioning rotating shaft is simple in structure, and is easy to use, is easy to produce.
2. of many uses, can be used for free door, revolving door, pivoted window etc.
Below in conjunction with drawings and Examples the present invention is made a detailed description.
