Description

Technical Field

[0001] The present invention relates to the technical field of anti-glare screen installation mechanisms, and specifically relates to an adjustable folding anti-glare screen installation mechanism. Background Art

[0002] The anti-glare screen is one of the most commonly used products among the peripheral devices of projectors. When in use, in order to be vertically unfolded in front of people, the anti-glare screen is generally assembled on a screen mounting frame. The structure of the traditional screen mounting frame includes an outer frame, an inner frame and a connecting rod. The screen is installed on the inner frame through a spring buckle, and then the outer frame covers the spring and is assembled on the inner frame. In this way, the elastic effect of the spring is used to make the screen unfold flatly.

[0003] However, the installation structure of the traditional anti-glare screen has the following deficiencies:

[0004] 1) When assembling the frame, screws are generally used for assembly, with many components, a long on-site installation time and cumbersome operations.

[0005] 2) The installation time at the user's home is long, and problems such as the anti-glare screen being not tight enough and the anti-glare screen being uneven will occur.

[0006] 3) When disassembling and storing, there are also many components, the disassembly is complex and it is not convenient for storage.

[0007] 4) The traditional screen mounting frame is welded with hanging ears, and the positions of the hanging ears are fixed. When hanging the hanging ears on a wall or other installation positions, high fitting accuracy is often required. Otherwise, the screen cannot be hung on the wall or other installation positions, the operation is cumbersome, and it is also difficult to adapt to changes in the installation position, with poor applicability and large limitations in use.

The frame assembly includes an inner frame combined rack, an outer frame combined rack 2 installed on the outer edge of the inner frame combined rack, and a connecting rod 3 connected to the inner side of the inner frame combined rack. Among them, the inner frame combined rack includes an inner frame folding cross rack 4 and an inner frame longitudinal rack 5 that are sequentially assembled to form an inner frame installation rack. The inner frame folding cross rack 4 and the inner frame longitudinal rack 5 are respectively provided with an adjustment assembly, an adjustment connecting frame 6, and an adjustment spring 7 for adjusting the tension of the anti-light curtain 1. The adjustment connecting frame 6 is arranged on the inner frame folding cross rack 4 and the inner frame longitudinal rack 5. The adjustment assembly includes an adjustment screw 8 and an adjustment nut 9. The adjustment screw 8 is rotatably connected to the inner frame folding cross rack 4 and the inner frame longitudinal rack 5. The adjustment nut 9 is fixedly installed on the adjustment connecting frame 6 and is threadedly connected to the adjustment screw 8. One end of the adjustment spring 7 is buckled on the adjustment connecting frame 6, and the other end of the adjustment spring 7 is buckled on the side edge of the anti-light curtain 1.

[0034] In the optimized solution, the inner frame folding cross frame 4 and the inner frame longitudinal frame 5 are provided with adjustment slots 12, and the adjustment connecting frames 6 are respectively installed in the adjustment slots 12 and can slide in and out in the adjustment slots 12. Moreover, the adjustment connecting frame 6 is provided with a positioning slot 15, the adjustment nuts 9 are respectively slidably installed in the positioning slot 15, one end of the adjustment spring 7 is provided with a clamping position 71 for sliding in the positioning slot 15, and the other end of the adjustment spring 7 is provided with a hook 72 for buckling on the side of the anti-glare curtain 1. During this period, the inner frame folding cross frame 4 and the inner frame longitudinal frame 5 are respectively provided with limit posts 13 for restricting the in-and-out sliding position of the adjustment connecting frame 6, and the adjustment connecting frame 6 is provided with a limiting slot 14 for sliding connection with the limit posts 13.

[0035] When installing the anti-glare curtain 1, first slide the adjustment nuts 9 and the clamping positions 71 of the adjustment springs 7 into the positioning slots 15 respectively, and then install the adjustment screws 8 on the inner frame folding cross frame 4 and the inner frame longitudinal frame 5 respectively and thread them with the corresponding adjustment nuts 9. And, use the hook 72 of the spring to buckle on the four sides of the anti-glare curtain 1. During this period, according to actual applications, rotate the adjustment screw 8 to drive the adjustment connecting frame 6 to slide in or out, so as to adjust the tension of the anti-glare curtain 1, make the anti-glare curtain 1 unfold vertically and flatly, and improve the use effect of the anti-glare curtain 1.

Among them, the elastic hook 23 includes a mounting plate 231, a torsion spring 232, a hook 233, and a locking screw 234. The mounting plate 231 is slidably connected to the connecting rod 3. The locking screws 234 are respectively connected to the left and right sides of the mounting plate 231 and fix the two ends of the hook 233 to the left and right sides of the mounting plate 231. The middle part of the hook 233 swings up and down with its two ends as fixed points. The torsion spring 232 is sleeved between the locking screw 234 and the hook 233, and one end of the torsion spring 232 is buckled on the mounting plate 231, and the other end of the torsion spring 232 is mounted on the middle part of the hook 233.

[0044] During assembly, the hanging ear 24 is installed on the wall or other positions. The elastic hook 23 slides to the specified position on the connecting rod 3 corresponding to the hanging ear 2412. Then rotate the locking screws 234 on both sides to fix the elastic hook 23 on the connecting rod 3, and then buckle the elastic hook 23 on the hanging ear 24, so that the anti-glare curtain 1 is installed on the wall or other specified positions. The installation is convenient, the structure is stable, and it can adapt to the change of the curtain installation position, meet the requirements, and reduce the use limitations.
