Abstract
The utility model discloses an installation structure of a projecting screen which includes a frame, a joint used for connecting the edge of a curtain; and a position adjuster adjusting the distance between the frame and the joint is arranged between the frame and the joint. The position adjuster includes a screw and a nut connected with the screw in a screwing way; and one hole is arranged on the fame. The screw penetrates the hole; the lower end of the screw is connected with the joint; and the upper end of the hole is connected with the nut. Compared with the prior art, the installation structure of the projecting screen fixedly connects the curtain with the joint and connects the joint with the frame through the position adjuster; the curtain fixed on the joint can be stretched through the adjuster, thereby properly adjusting the evenness of the curtain and guaranteeing the curtain from being deformed due to the change of time, temperature, humidity, etc.
Description
Technical field:
This utility model relates to the mounting structure of projection screen, is mainly the screen installing mechanism that scrollable projection hard curtain is made the plane or the face of cylinder.
Background technology:
When superhuge projection hard curtain is installed, can't solve the flatness problem of screen.
Habitual way is: 1, the hard curtain in plane: cut frame by hard curtain size, the material of frame is plastic-steel or timber.Then hard curtain edge is inserted in the frame groove, again four angles of frame are got final product with the web member connection.Bigger as screen, the article that then serve as a contrast other materials such as batten, metal side tube in hard curtain behind with adhesive tape keep the smooth of act face.
2, cylindrical hard curtain: 1. a hard curtain coboundary is fixed on the ready-made framework with screw, appoints hard curtain sagging naturally, then hard curtain other three fix with screw and to get final product.2. stick on the framework with adhesive tape at the hard curtain back side.Though above several method can solve the planarization problem of hard curtain at short notice, along with the variation of time, temperature, humidity, hard curtain will be out of shape, play drum or come off.It is poor that hard curtain is installed rear stability, and quality can't guarantee.
Summary of the invention:
This technical problem to be solved in the utility model is at above-mentioned the deficiencies in the prior art, and provides a kind of projection hard curtain flatness adjustable mounting structure, solves the flatness problem that scrollable projection hard curtain is installed.
For solving the problems of the technologies described above, this the technical solution adopted in the utility model is: a kind of mounting structure of projection hard curtain, it is characterized in that: comprise frame, be used to connect the joint at curtain edge, between described frame and joint, be provided with one and regulate the apparatus for adjusting position of frame and joint spacing.
Described apparatus for adjusting position comprises a screw rod and a nut that is connected with this screw flight, and a hole is set on described framework, and described screw rod passes described hole, and its lower end is connected with joint, connects described nut in the upper end in hole.
Compared with prior art, the utility model is fixedly connected on curtain on the joint, and joint connected in frame by apparatus for adjusting position, can the curtain that be fixed on the joint be stretched by regulating device, thereby the flatness of in good time adjusting curtain guarantees that curtain can be because of distortion such as variation such as time, temperature, humidity.
