Description

TECHNICAL FIELD

[0001] The utility model belongs to metal screen technical field, concretely relates to a mounting structure of metal screen. BACKGROUND

[0002] The metal screen is coated with a layer of metal coating on the surface, which can better reflect light, making the image brighter and clearer, thereby providing higher contrast and color reproduction. This feature enables the metal screen to make the black color deeper and the white color brighter when playing movies, thereby enhancing the detail performance of the image. When watching movies outdoors, a movie screen frame needs to be used. The existing movie screen frame generally inserts the insertion rod into the ground first, and then manually expands the support frame around the insertion rod to make the support frame abut against the ground, thereby achieving better support and fixing effect. However, this manual expansion operation of the support frame is relatively cumbersome, and it is necessary to ensure the stability of the screen frame, which increases the operation difficulty during support.

[0003] The patent with the publication number CN211478855U relates to a screen mounting frame, which includes an insertion rod, the middle part of the insertion rod is provided with an annular stop ring, the front and rear and left and right surfaces of the lower part of the insertion rod are rotationally provided with support legs, and the bottom of the annular stop ring is fixedly provided with four blocking blocks, which are in one-to-one corresponding limiting cooperation with the support legs.

[0004] However, the above-mentioned scheme still needs the operator to manually break open the multiple support legs after inserting the insertion rod into the ground. The process of breaking open the multiple support legs is relatively cumbersome, which not only increases the operation difficulty of the staff during support, but also increases the workload of the staff, and the actual use effect is poor. At the same time, the position of the blocking block in the above-mentioned scheme is fixed, which makes the angle of rotation of the support leg fixed, and the depth of insertion of the insertion rod fixed, thereby causing the above-mentioned scheme unable to adaptively adjust the depth of insertion of the insertion rod according to different geological environments, the applicable range is small, and the actual use has certain limitations.

A reel 12 is rotatably arranged between the two fixed shafts 11, the outer surface of the reel 12 is provided with a metal screen 14, the two ends of the reel 12 are rotatably connected with the opposite sides of the two fixed shafts 11 respectively, and the two ends of the reel 12 are fixedly connected with the clock spring 13 in the fixed shaft 11.

[0026] The bottom of the metal screen 14 is fixedly provided with a cross rod 15, a hook 16 is fixedly arranged on the mounting frame 9, the hook 16 is clamped and limited with the cross rod 15, and the metal screen 14 after being unfolded is limited through the hook 16. In addition, the bottom of each fixed shaft 11 is provided with a clamping groove 17, the clamping groove 17 is matched with the cross rod 15 and is used for limiting the cross rod 15, so that the metal screen 14 is prevented from being loose.

[0027] The cross rod 15 is pulled, so that the metal screen 14 is unfolded, the metal screen 14 drives the reel 12 to rotate and winds the clock spring 13. After the metal screen 14 is unfolded to a suitable position, the cross rod 15 is clamped on the hook 16, so that the fixing of the metal screen 14 is completed.

[0028] The bottom of each supporting leg 91 is slidably penetrated by a plug rod 1, the bottom of the plug rod 1 is conically arranged, and each supporting leg 91 is provided with a limiting piece acting on the plug rod 1, and the limiting piece can be used to adjust the height of the metal screen 14 in the vertical direction.

[0029] The limiting piece is a bolt 10, a threaded hole is formed in the outer surface of the supporting leg 91, the bolt 10 is threadedly penetrated through the threaded hole and abuts against and limits the outer surface of the plug rod 1. The bolt 10 is rotated to release the limitation of the plug rod 1 by the bolt 10, so that the plug rod 1 and the supporting leg 91 relatively slide, thereby adjusting the height of the metal screen 14. After being adjusted to a suitable position, the bolt 10 is reversely rotated to abut against and limit the plug rod 1 again.

[0030] The outer surface of the supporting leg 91 is fixedly provided with a fixed ring 7, the circumferential surface of the fixed ring 7 is rotatably provided with a plurality of second connecting rods 5, and the end of each second connecting rod 5, which is not connected with the fixed ring 7, is rotatably provided with a supporting leg 6. The outer surface of the plug rod 1 is slidably provided with a sliding block 2, the outer surface of the sliding block 2 is rotatably provided with a plurality of first connecting rods 3, the number of the first connecting rods 3 is equal to that of the second connecting rods 5 and one-to-one corresponds, and the end of each first connecting rod 3, which is not connected with the sliding block 2, is rotatably connected with the middle part of the corresponding second connecting rod 5 through a rotating shaft 4.

[0031] In addition, the supporting leg 91 and the sliding block 2 are provided with a spring 8, the spring 8 is sleeved on the outer surface of the plug rod 1, the top of the spring 8 is fixedly connected with the bottom of the supporting leg 91, and the bottom of the spring 8 is fixedly connected with the top of the sliding block 2.

[0032] In the process of inserting the insertion rod 1 into the ground, the sliding block 2 will contact the ground, thereby pushing the sliding block 2 to slide relative to the insertion rod 1, so that the compression deformation amount of the spring 8 gradually increases. At the same time, the first connecting rod 3 will push the second connecting rod 5 to rotate around the connection between the second connecting rod 5 and the fixed ring 7, so that the second connecting rod 5 is opened outward, and the supporting leg 6 will rotate under the action of its own gravity and keep parallel to the ground. When the supporting leg 6 contacts the ground, the insertion of the insertion rod 1 is completed, and the second connecting rod 5 and the supporting leg 6 will support the insertion rod 1, thereby improving the stability of the device.

[0033] In this process, the connecting end of the first connecting rod 3 and the sliding block 2 will rotate around the connection between the first connecting rod 3 and the sliding block 2, and the connecting end of the first connecting rod 3 and the second connecting rod 5 will rotate around the connection between the first connecting rod 3 and the second connecting rod 5.

[0034] Working principle: when playing outdoor movies in the open air using a metal screen 14, the insertion rod 1 is inserted into the ground. In the process of inserting the insertion rod 1 into the ground, the sliding block 2 will contact the ground, thereby pushing the sliding block 2 to slide relative to the insertion rod 1, so that the compression deformation amount of the spring 8 gradually increases. At the same time, the first connecting rod 3 will push the second connecting rod 5 to rotate around the connection between the second connecting rod 5 and the fixed ring 7, so that the second connecting rod 5 is opened outward, and the supporting leg 6 will rotate under the action of its own gravity and keep parallel to the ground. When the supporting leg 6 contacts the ground, the insertion of the insertion rod 1 is completed, and the second connecting rod 5 and the supporting leg 6 will support the insertion rod 1, thereby improving the stability of the device.

[0035] In this process, the connecting end of the first connecting rod 3 and the sliding block 2 will rotate around the connection between the first connecting rod 3 and the sliding block 2, and the connecting end of the first connecting rod 3 and the second connecting rod 5 will rotate around the connection between the first connecting rod 3 and the second connecting rod 5.

[0036] Subsequently, the bolt 10 is rotated to release the restriction of the bolt 10 on the insertion rod 1, so that the insertion rod 1 slides relative to the supporting leg 91, thereby adjusting the height of the metal screen 14. After adjusting to the appropriate position, the bolt 10 is reversely rotated to re-complete the abutting and limiting of the insertion rod 1.

[0037] Then, the cross rod 15 is pulled to expand the metal screen 14, and the metal screen 14 drives the reel 12 to rotate and winds the clockwork spring 13. When the metal screen 14 is expanded to the appropriate position, the cross rod 15 is buckled on the hook 16, thereby completing the fixation of the metal screen 14.

[0038] When winding, the cross rod 15 is taken out of the hook 16, and the clockwork spring 13 is reset to drive the reel 12 to rotate, thereby winding the metal screen 14 on the reel 12. Subsequently, the cross rod 15 is buckled into the clamping groove 17 on the fixed shaft 11, which is used to prevent the metal screen 14 wound on the reel 12 from being loose.

[0039] Finally, the plug rod 1 is pulled out of the ground. The spring 8 pushes the sliding block 2 to reset during the process of pulling out the plug rod 1. The spring 8 has small elastic force, is only used for resetting the sliding block 2, and cleans the soil adhered on the plug rod 1 during the resetting process of the sliding block 2.
