Description

Technical Field

[0001] The utility model relates to a frame screen, in particular to a detachable portable frame screen, belonging to the technical field of screens. Background Art

[0002] A screen is a screen used to project enlarged images (pictures) when showing movies and slides. The original screen was made of white cloth. In order to increase the reflectivity of light and keep the projected image bright enough, the diffuse reflection screen used in general theaters is made of cloth or plastic coated with barium sulfate or metal powder. The types of screens include frame screens.

[0003] The existing frame screen is usually connected to the wall or mounting plate using mounting bolts. When the staff needs to transfer or inspect and maintain the frame screen, they need to remove the fixed mounting bolts one by one. The disassembly process is very troublesome, which leads to low disassembly efficiency.

[0004] Therefore, a detachable portable frame screen is proposed. Utility Model Content

[0009] Further preferably, slide grooves are provided on both left and right sides of the inner cavity of the disassembly box, slide rods are welded on both sides of the movable block, and the slide rods are slidably connected in the slide grooves.

[0010] Further preferably, a limiting groove is provided on the front side of the disassembly box, a movable rod is welded on the front side of the movable block, and an outer wall of the movable rod is tightly fitted with the limiting groove.

[0011] Further preferably, mounting bolts are threadedly connected around the inner surface of the mounting plate, and the back sides of the mounting bolts penetrate to the back side of the mounting plate.

[0012] The embodiment of the utility model has the following advantages due to the adoption of the above technical solution:

[0013] 1. The utility model drives the movable block to move horizontally by pulling the movable rod outward, and the movable block squeezes the spring to deform due to the influence of force. At the same time, the movable block drives the clamping block to move horizontally through the movable rod and the connecting plate. Finally, after the movable rod is loosened, the spring is deformed again due to the influence of the loss of force and drives the clamping block to be clamped in the clamping slot, thereby realizing rapid installation and disassembly of the frame body and improving the efficiency of later disassembly.

[0014] 2. The utility model can facilitate the staff to pick up and carry the frame body and the screen body by providing a grip rod and an anti-slip cover. At the same time, due to the provision of the anti-slip cover, it can play an anti-slip effect and prevent the staff from slipping when holding the grip rod to take the screen. By providing a sliding groove and a sliding rod, the movable block can be limited to improve its stability during movement. By providing a limiting groove, the movable rod can be limited to prevent it from deflecting during movement. By providing mounting bolts, it is convenient for personnel to install the mounting plate.

[0022] In the following, only some exemplary embodiments are briefly described. As those skilled in the art will appreciate, the described embodiments may be modified in various ways without departing from the spirit or scope of the present invention. Therefore, the drawings and descriptions are considered to be exemplary and non-restrictive in nature.

[0023] The embodiments of the present utility model are described in detail below with reference to the accompanying drawings.

[0024] like Figure 1-4 As shown, the embodiment of the utility model provides a detachable portable frame screen, including a mounting plate 1 and a frame body 7, a screen body 8 is arranged on the inner side of the frame body 7, an insert block 11 is welded on the back side of the frame body 7, a slot 9 is opened on the front side of the mounting plate 1, and the insert block 11 is inserted into the slot 9, and a card slot 10 is opened on the left and right sides of the top of the frame body 7, and a disassembly mechanism 5 is arranged on the upper and lower sides of the surface of the mounting plate 1, and the disassembly mechanism 5 includes a disassembly box 501, and the disassembly box 501 is fixedly connected to the upper and lower sides of the surface of the mounting plate 1, a spring 503 is arranged on the outer side of the inner cavity of the disassembly box 501, and a movable block 505 is arranged on the inner side of the spring 503, a moving rod 509 is welded on the inner side of the movable block 505, a connecting plate 508 is welded on the inner side of the moving rod 509, and a card block 507 is welded on both sides of the inner side of the connecting plate 508, and the card block 507 is connected to the card slot 10.

[0025] In this embodiment, the movable rod 502 is pulled outward to drive the movable block 505 to move horizontally, and the movable block 505 squeezes the spring 503 to deform due to the influence of force. At the same time, the movable block 505 drives the clamping block 507 to move horizontally through the movable rod 509 and the connecting plate 508. Finally, after the movable rod 502 is released, the spring 503 is deformed again due to the loss of force and drives the clamping block 507 to be clamped in the clamping slot 10, thereby realizing the rapid installation and disassembly of the frame body 7 and improving the efficiency of later disassembly.

[0026] In one embodiment, grip rods 3 are welded on both sides of the frame body 7, and the surface of the grip rods 3 is covered with anti-slip sleeves 2. Slide grooves 504 are provided on the left and right sides of the inner cavity of the disassembly box 501, and slide rods 506 are welded on both sides of the movable block 505, and the slide rods 506 are slidably connected in the slide grooves 504. A limiting groove 6 is provided on the front side of the disassembly box 501, and a movable rod 502 is welded on the front side of the movable block 505, and the outer wall of the movable rod 502 is tightly fitted with the limiting groove 6. The inner surface of the mounting plate 1 is threadedly connected with mounting bolts 4, and the back side of the mounting bolts 4 penetrates to the back side of the mounting plate 1.

[0027] In this embodiment, by providing the grip 3 and the anti-slip cover 2, it is convenient for the staff to pick up the carrying frame body 7 and the screen body 8. At the same time, due to the provision of the anti-slip cover 2, it can have an anti-slip effect and prevent the staff from slipping when holding the grip 3. By providing the slide groove 504 and the slide rod 506, the movable block 505 can be limited to improve its stability during movement. By providing the limiting groove 6, the movable rod 502 can be limited to prevent it from deflecting during movement. By providing the mounting bolts 4, it is convenient for personnel to install the mounting plate 1.

[0028] The utility model is in operation: when the frame body 7 and the screen body 8 need to be installed, first, the movable block 505 is driven to move outward by pulling the movable rod 502 outward, and the movable block 505 drives the clamping block 507 to move outward through the movable rod 509 and the connecting plate 508. At this time, the spring 503 is deformed due to the extrusion of the movable block 505, and then the plug block 11 is inserted into the slot 9, and then the movable rod 502 is released. At this time, the spring 503 is deformed again due to the loss of force and drives the movable block 505 to move inward, and the movable block 505 is moved through the movable rod 509 and the connecting plate 508 drive the card block 507 to move inward and engage in the card slot 10, thereby limiting the frame body 7 and completing its quick installation. When the frame body 7 and the screen body 8 need to be disassembled, the movable rod 502 is also pulled outward to drive the movable block 505 to move outward. The movable block 505 drives the card block 507 to move outward and leave the card slot 10 through the movable rod 509 and the connecting plate 508, thereby releasing the limit on the frame body 7. Finally, the staff holds the handle 3 and pulls it forward to drive the plug block 11 to leave the slot 9, thereby completing its quick disassembly.

[0029] The above is only a specific implementation of the utility model, but the protection scope of the utility model is not limited thereto. Any technician familiar with the technical field can easily think of various changes or substitutions within the technical scope disclosed by the utility model, which should be included in the protection scope of the utility model. Therefore, the protection scope of the utility model should be based on the protection scope of the claims.
