Abstract
The utility model discloses a projection screen and border connecting device which comprises a square border and a square projection screen smaller than the square border, wherein at most one side of the projection screen contacts with the border and is fixed; the other sides of the projection screen do not contact with the border; each side of the projection screen not in contact with the border is connected with the border through multiple pull rods; the middle section of the pull rod is threaded on the border; one end of the pull rod is fixed with the projection screen; an adjusting nut is screwed at the other end of the pull rod back on to the projection screen; a spring is sleeved on the pull rod and located between the adjusting nut and the border; and gaskets also can be arranged on the two sides of the spring. The device disclosed by the utility model can overcome the influence of heat expansion and cold contraction on the projection screen, keeps the flatness of the projection screen and is convenient to mount.
Description
Technical field
The utility model relates to jumbotron projection display technique field, the coupling arrangement of especially a kind of projection screen and frame.
Background technology
Generally; To be installed to projection screen on the frame, need the professional to be stacked in each limit of projection screen on the frame, tension place of projection screen and frame fixed while strain then with screw; For making projection screen that flatness preferably can be arranged, its installation difficulty is bigger; And after projection screen and frame fix, when projection screen runs into the shrinkage size decreases, draw the place of fixing of projection screen and frame badly easily, when projection screen ran into the heat expansion size and becomes big, making projection screen produce fold easily influenced its flatness.
The utility model content
The technical matters that the utility model will solve provides the coupling arrangement of a kind of projection screen and frame, and it can overcome the influence that projection screen is expanded with heat and contract with cold, and keeps the flatness of projection screen, and easy for installation.
For achieving the above object, the technical scheme of the utility model is: the coupling arrangement of a kind of projection screen and frame comprises square frame, the size square projection screen less than square frame; Projection screen limit at the most contacts with frame and forms fixing; It is characterized in that: other limit of projection screen does not contact with frame, and projection screen is connected with frame through a plurality of pull bars with discontiguous each limit of frame, and described pull bar stage casing is through on the frame; One end and the projection screen of pull bar fix; The pull bar rear projection screen other end is rotary with the adjustment nut, is installed with spring on the pull bar, and described spring is between adjustment nut and the frame.
Further; Described pull bar and projection screen fix an end and are provided with U type termination; Be processed with corresponding through hole on two sidewalls of U type termination; Projection screen is clipped in the intermediate groove of U type termination and passes through screw that corresponding through hole fixes projection screen and described U type termination on two sidewalls of projection screen and U type termination, and this structure helps improving the assembly performance of pull bar and projection screen.
Further again, the both sides of described spring are provided with pad, make spring more stablize and play a role.
The utility model is because projection screen limit contacts with frame and forms fixingly at the most, and other limit of projection screen all is connected with frame through a plurality of pull bars, and the pull bar stage casing is through on the frame; One end and the projection screen of pull bar fix, and the pull bar rear projection screen other end is rotary with the adjustment nut, on the pull bar between adjustment nut and the frame, are installed with spring; When projection screen receives shrinkage effect size decreases; Spring further compresses, and pull bar is diminished by the shrinkage effect toward projection screen one side shifting compensation projection screen size is when projection screen receives heat expansion effect size to become big; Spring opens; Pull bar receives the heat expansion effect to become big size toward frame one side shifting compensation projection screen, therefore can overcome the influence that projection screen expands with heat and contract with cold, and keeps the flatness of projection screen.
On the other hand; Because of projection screen limit contacts with frame and forms fixing at the most; Other limit and frame of projection screen adopts fit to be connected through parts such as pull bar, spring, adjustment nuts, therefore more convenient, common operating personnel is installed and also can accomplishes; Adjust the pulling force that nut can also change pull bar through rotation, make that the pulling force of each pull bar can be different, the flatness of convenient adjustment projection screen.

Embodiment
Below in conjunction with accompanying drawing and concrete embodiment the utility model is done further explain.
Embodiment one, Fig. 1 be to shown in Figure 3, and the coupling arrangement of a kind of projection screen and frame comprises square frame 1, the size square projection screen 2 less than square frame; A limit of projection screen 2 contacts with frame 1 and fixes through a plurality of screws 11; Projection screen 2 other three limits do not contact with frame 1, and projection screen 2 is connected with frame 1 through a plurality of pull bars 3 with frame 1 discontiguous each limit, and described pull bar 3 stage casings are through on the frame 1; One end and the projection screen 2 of pull bar 3 fix; Pull bar 3 rear projection screens 2 other ends are rotary with adjustment nut 4, are installed with spring 5 on the pull bar 3, and described spring 5 is between adjustment nut 4 and the frame 1.
Pull bar 3 fixes and can realize through following structure with projection screen 2; Fix an end at described pull bar 3 with projection screen 2 and be provided with U type termination 31; Be processed with corresponding through hole on two sidewalls of U type termination 31, projection screen 2 is clipped in 31 intermediate groove of U type termination and passes through screw 32 that corresponding through hole fixes projection screen 2 and described U type termination 31 on two sidewalls of projection screen 2 and U type termination 31.
The both sides of above-mentioned spring 5 also can be provided with pad 6.
Embodiment two, and is shown in Figure 4, and what they were different with embodiment one is, four limits of projection screen 2 all do not contact with frame 1, and each limit of projection screen 2 all is connected with frame 1 through a plurality of pull bars 3.
Below only be preferred embodiment of the utility model, the change that those skilled in the art does to be equal to by claim all falls into the protection domain of this case.
