[0035] The utility model is further described below in conjunction with the accompanying drawings and embodiments:

[0036] Embodiment 1: A screen installation structure, see Figures 1 to 4 , including a fixing plate A1, a positioning block 2, a fixing plate B3, a slide rail 4, an L-shaped plate A5 and an L-shaped plate B6;

[0037] The fixing plate A1 is fixed on the roof; the positioning block 2 is fixed on the bottom side of the fixing plate A1; the fixing plate B3 is fixed on the top of the curtain shell; the two slide rails 4 are symmetrically arranged on the outer ends of the top side of the fixing plate B3; the vertical end of the L-shaped plate A5 is fixedly connected to the sliding ends of the two slide rails 4; wherein, the horizontal section of the L-shaped plate A5 is inserted into the through groove 201 provided on the positioning block 2; the horizontal section of the L-shaped plate B6 is fixedly arranged on the inner end of the top side of the fixing plate B3; wherein, two springs 7 are symmetrically arranged between the vertical section of the L-shaped plate B6 and the vertical section of the L-shaped plate A5, and the two ends of the spring 7 are fixedly connected to the vertical section of the L-shaped plate B6 and the vertical section of the L-shaped plate A5 respectively, and the elastic coefficient of the spring 7 is selected by the technicians of this profession according to the actual situation. The entire installation structure is provided with two, two fixing plates A1 are symmetrically fixed on the roof installation position, and two fixing plates B3 are symmetrically fixed on the top of the curtain shell.

[0038] The utility model has the advantages of quickly positioning the curtain shell at the roof installation position by arranging the fixing plate A1, the positioning block 2, the fixing plate B3, the slide rail 4, the L-shaped plate A5, the L-shaped plate B6 and the spring 7, which is convenient for installation and disassembly and maintenance, and solves the problem that the screw fixing method is difficult to disassemble and repair when the curtain fails and the disassembly is time-consuming.

[0039] Specifically, the entrance end of the through slot 201 is configured as a trumpet-shaped opening; the horizontal section of the L-shaped plate A5 is more easily inserted into the through slot 201 from the trumpet-shaped opening.

[0040] Furthermore, a handle 9 is fixedly provided on the outer side of the vertical section of the L-shaped plate A5; holding the handle 9 facilitates pulling the L-shaped plate A5 to move.

[0041] Furthermore, a positioning structure 8 is arranged inside the horizontal section of the L-shaped plate B6;

[0042] The positioning structure 8 includes a threaded sleeve 801, a screw rod 802, a handle 803 and a positioning column 804;

[0043] The bottom end of the threaded sleeve 801 is fixed on the inner side of the horizontal section of the L-shaped plate B6; the screw 802 is threadedly arranged in the threaded sleeve 801; the handle 803 is fixed on the top of the screw 802; the positioning column 804 is fixed on the top side of the handle 803; wherein, the top of the positioning column 804 is plugged into and matched with the positioning hole 501 opened on the inner side of the horizontal end of the L-shaped plate A5.

[0044] The utility model has the advantage of positioning the horizontal end of the L-shaped plate A5 passing through the through slot 201 by setting a threaded sleeve 801, a screw rod 802, a rotating handle 803, a positioning column 804 and a positioning hole 501, so that the horizontal section of the L-shaped plate A5 and the positioning block 2 can be stably docked, thereby maintaining the stable installation of the shell.

[0045] Working principle: using the device of the utility model, the two fixing plates A1 are symmetrically fixed at the roof installation position, and the two fixing plates B3 are symmetrically fixed at the top of the curtain shell. The curtain shell is lifted to the roof installation area, and the two holding handles 9 are respectively held to pull the two L-shaped plates A5 away from each other. Driven by the slide rail 4, the L-shaped plate A5 moves stably, and the spring 7 is stretched until the L-shaped plate A5 moves to the position where the outer end of the slide rail 4 cannot move anymore. The fixing plate A1 is matched with the fixing plate B3, and the vertical end of the L-shaped plate B6 contacts the inner side of the bottom end of the positioning block 2. The force of the holding handle 9 is slowly removed. Under the action of the spring 7, the two L-shaped plates A5 move relative to each other, and the horizontal section of the L-shaped plate A5 passes through the through groove 201 until the inner side of the vertical section of the L-shaped plate A5 contacts the positioning block 2 and stops. Turn the handle 803, and the screw 802 rotates and moves upward relative to the threaded sleeve 801 until the top of the positioning column 804 is inserted into the positioning hole 501 for positioning, thereby completing the installation of the curtain shell. To disassemble, just reverse the above steps.
