The utility model relates to the big screen splicing technology, in particular to a screen supporting and regulating mechanism. The screen supporting and regulating mechanism comprises a permanent seat, a cam, a rotation piece, a linkage piece and a locking piece, wherein the inside of the permanent seat is hollow; the permanent seat is provided with an opening; the end surface of the front end of the permanent seat is provided with a through hole and a mounting cylinder which is communicated with the through hole and is outwards extruded; the linkage piece is installed in the through hole and the mounting cylinder; one end of the linkage piece is connected with the end surface of one end of the cam; the other end of the linkage piece is positioned in the hollow opening of the permanent seat; the rotation piece is installed on the tail end of the other end of the linkage piece; and the mounting cylinder is provided with a locking hole used for installing the locking piece. According to the screen supporting and regulating mechanism disclosed by the utility model, the rotation piece is rotated by utilizing a lever principle, and therefore the linkage piece drives the cam to rotate so as to regulate the height of a screen contacted with the curved surface of the cam. The screen supporting and regulating mechanism has a simple structure and is convenient to for install and regulate regulating the height of the screen. When an abutted seam between spliced units in the screen is largened, the cam is regulated so as to regulate the height of the screen, the size of the abutted seam is changed, and the display effect of a screen picture is improved.
Description
Technical field
The utility model relates to the large-screen splicing technology, is specifically related to a kind of screen support controlling mechanism.
Background technique
When realizing large-screen splicing, large-screen splicing wall is comprised of a plurality of concatenation units, can form the physics splicing seams between the concatenation unit.In order to improve the size of splicing seams, generally be provided with the adjustment that regulating device carries out the piece size on the screen frame, when the slit occurring and become large, need to ask experienced on-the-spot installation personnel from the position of new check and correction screen frame, adjust the slit of screen, complicated operation with this, and rely on very much adjustment with operator, and since the regulating device adjustment be screen frame, be not directly to the screen adjustment, the DeGrain of improvement.
The model utility content
The technical problem that the utility model solves is to overcome the deficiencies in the prior art, can directly adjust the screen support controlling mechanism that screen piece size is improved picture effect well thereby provide a kind of.
For solving the problems of the technologies described above, the technical solution of the utility model is as follows:
A kind of screen support controlling mechanism, comprise fixed base, cam, rotating component, coupling component and locking element, fixed base inner hollow and opening, the mounting cylinder that its front end end face is provided with through hole and communicates and outwards give prominence to through hole, coupling component is installed in through hole and the mounting cylinder, and the one end is connected with the end face of cam one end, and its other end is positioned at the inside of fixed base hollow open, rotating component is installed in the end of the coupling component the other end, and mounting cylinder is provided with for the locking hole that locking element is installed.The utility model utilizes lever principle to rotate rotating component, so that coupling component band moving cam rotates, cam is the height of capable of regulating and the contacted screen of its curved surface after rotating.
As a kind of preferred version, the described coupling component the other end is provided with groove near the position that rotating component is installed, and bounding means is installed on the groove.Bounding means is set carries out spacingly to the other end of coupling component, guarantee when coupling component rotates not in the through hole of fixed base and mounting cylinder, to deviate from.
As further preferred version, described bounding means is E type ring.
As a kind of preferred version, described coupling component is rotating shaft.
As further preferred version, described rotating shaft surface arranges annular knurl.Annular knurl can increase locking element and lock the frictional force of paying between rear and the rotating shaft, increases the locking force of locking element.
As a kind of preferred version, described locking element is screw, and the locking hole on the mounting cylinder is tapped hole.Screw worked itself loose opens and locks tightly very convenient, when needs are adjusted screen screw is unclamped and can operate rotating component, only needs just coupling component locking of locking nut after adjusting the screen position, and is very simple and convenient.
As a kind of preferred version, described mounting cylinder inner wall smooth.The mounting cylinder inner wall smooth makes things convenient for coupling component to rotate in mounting cylinder.
As a kind of preferred version, described coupling component the other end end is provided with for the position, hole that rotating component is installed.
As further preferred version, described coupling component is bar.
As a kind of preferred version, described fixed base rear end end face is provided with the mounting hole for mounting-fixing base.Fixed base can be installed on the framework of screen by this mounting hole.
Compared with prior art, the beneficial effect of technical solutions of the utility model is:
(1) the utility model is simple in structure, is convenient to install the height with adjusting screen, and when the piece between the concatenation unit in the screen occurs to become large situation, thereby the height of adjustment cam adjusting screen changes the piece size, improves the display effect of screen-picture.
(2) the utility model is installed on the screen frame, and the flatness of itself and screen suits better, is not easy to give prominence to, and the cam front on it can keep a plane with screen, also can than the inside indentation of screen, not affect the adjusting of screen height.
