Description

Technical Field

[0001] This utility model relates to the field of metal screen technology, and in particular to a metal screen with adjustable screen holes. Background Technology

[0002] Black soldier flies are saprophytic insects. Their larvae feed on animal feces, rotten fruits and vegetables, etc. They have a varied diet, a large appetite, overlapping life cycles, and strong resistance to adverse conditions. They also have migratory habits before pupation. The larval stage of black soldier flies is the main stage in which they feed and participate in the treatment of organic waste, and can convert organic waste such as poultry and livestock manure and kitchen waste into protein and fat.

[0003] Breeding cages are facilities used to raise specific insects, such as black soldier flies, for ease of management and reproduction. Breeding cages are usually made of metal frames to ensure structural stability and durability. During the use of breeding cages, metal screens are usually installed to act as physical barriers, reducing direct contact between different breeding areas and lowering the risk of disease transmission.

[0004] Chinese patent application publication number CN220941817U discloses an adjustable metal screen. This invention uses a motor to rotate a drive shaft, which in turn rotates a drive helical gear. The drive helical gear then rotates a transmission helical gear, which in turn rotates the transmission shaft, causing the adjustment gear to rotate. Since the first and second transmission chains mesh with the adjustment gear, the first transmission chain slowly moves the upper screen back and forth, while the second transmission chain slowly moves the lower screen left and right, thus adjusting the mesh size. However, this invention requires a motor to adjust the mesh size, resulting in high costs and hindering cost and resource conservation. Furthermore, the large footprint of the motor and transmission mechanism affects overall installation and the usability of the metal screen. Utility Model Content

[0005] To address the shortcomings of existing technologies, this invention provides a metal screen with adjustable mesh size, thus solving the problems mentioned in the background section.

[0006] In order to achieve the above purpose, the present invention adopts the following technical solutions:

[0007] An adjustable-aperture metal screen includes a first mounting frame, a first screen fixedly mounted on one side of the first mounting frame, a mounting block fixedly mounted on one side of the first mounting frame, a connecting plate mounted on one side of the mounting block via a positioning mechanism, a second screen fixedly mounted on one side of the connecting plate, an mounting groove formed on one side of the connecting plate, a connecting block fixedly mounted on one side of the first mounting frame, a slot formed on one side of the connecting block, a mounting post mounted on the inner wall of the slot via a reset mechanism, a second mounting frame fixedly mounted at the bottom of the first mounting frame, and an mounting mechanism provided on one side of the second mounting frame.

[0008] Preferably, the positioning mechanism includes a positioning groove formed on one side of the mounting block, and a positioning block is slidably mounted on the inner wall of the positioning groove. One side of the positioning block and one side of the connecting plate are fixedly mounted.

[0009] Preferably, the reset mechanism includes a sliding column slidably mounted on the inner wall of the slot, a movable plate fixedly mounted on one end of the sliding column, a spring fixedly mounted on the inner wall of the slot, one end of the spring and one side of the movable plate being fixedly mounted, and one side of the movable plate and one end of the mounting column being fixedly mounted.

[0010] Preferably, the mounting mechanism includes a mounting plate fixedly mounted on one side of the second mounting frame, and a first bolt is threaded onto the top of the mounting plate.

[0011] Preferably, a first hole is formed through one side of the first mounting frame, and a second hole is formed on the inner wall of the first mounting frame.

[0012] Preferably, a second bolt is threaded onto the top of the first mounting frame, one end of the second bolt penetrating the surface of the first mounting frame and threaded onto the surface of the second mounting frame.

[0013] Preferably, the inner wall of the mounting groove mates with the surface of the mounting column, and the second bolts are in four groups arranged in an array.

[0014] Compared with the prior art, the beneficial effects of this utility model are:

[0015] 1. When it is necessary to enlarge the screen hole, the installation column is moved by the reset mechanism so that the installation column is away from the inner wall of the installation groove. Then the connecting plate can be pulled to remove it, and the second screen can be removed. At the same time, the same operation is performed on the second installation frame to enlarge the screen hole.

[0016] 2. When the screen aperture needs to be reduced, the connecting plate can be positioned using the positioning mechanism. Simultaneously, the second screen is inserted into the inner wall of the first and second holes. The reset mechanism drives the mounting column to move, causing the mounting column to insert into the inner wall of the mounting groove, thus limiting the installation of the connecting plate and the second screen. This reduces the screen aperture, eliminating the need for a motor during the adjustment process, saving costs and resources. It also does not occupy much space and does not affect the overall installation, achieving the goal of convenient screen aperture adjustment. The structure is simple and easy to use.

Obviously, the embodiments described are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without making creative efforts are within the scope of protection of the present invention.

[0024] Example: Refer to Figure 1-5This utility model provides a technical solution: an adjustable-aperture metal screen, comprising a first mounting frame 1, a first hole 18 extending through one side of the first mounting frame 1, a second hole 19 forming the inner wall of the first mounting frame 1, a first screen 2 fixedly mounted on one side of the first mounting frame 1, and a mounting block 3 fixedly mounted on one side of the first mounting frame 1. A connecting plate 6 is mounted on one side of the mounting block 3 via a positioning mechanism. The positioning mechanism includes a positioning groove 4 formed on one side of the mounting block 3, and a positioning block 5 slidably mounted on the inner wall of the positioning groove 4. One side of the positioning block 5 and one side of the connecting plate 6 are fixedly mounted, facilitating the positioning of the connecting plate 6. A second screen 7 is fixedly installed on one side of the connecting plate 6. An installation groove 8 is opened on one side of the connecting plate 6. A connecting block 9 is fixedly installed on one side of the first mounting frame 1. A slot 10 is opened on one side of the connecting block 9. An installation column 14 is installed on the inner wall of the slot 10 through a reset mechanism. The reset mechanism includes a sliding column 11 that is slidably installed on the inner wall of the slot 10. A moving plate 13 is fixedly installed on one end of the sliding column 11. A spring 12 is fixedly installed on the inner wall of the slot 10. One end of the spring 12 is fixedly installed on one side of the moving plate 13. One side of the moving plate 13 is fixedly installed on one end of the installation column 14, which facilitates the reset of the installation column 14.

[0025] Specifically, a second mounting frame 15 is fixedly mounted on the bottom of the first mounting frame 1. A mounting mechanism is provided on one side of the second mounting frame 15. The mounting mechanism includes a mounting plate 16 fixedly mounted on one side of the second mounting frame 15. A first bolt 17 is threaded onto the top of the mounting plate 16 for easy assembly. A second bolt 20 is threaded onto the top of the first mounting frame 1. One end of the second bolt 20 penetrates the surface of the first mounting frame 1 and is threaded onto the surface of the second mounting frame 15. The inner wall of the mounting groove 8 mates with the surface of the mounting column 14. There are four sets of second bolts 20 arranged in an array. When the screen aperture needs to be enlarged, the mounting column 14 is moved by the reset mechanism, causing it to leave the inner wall of the mounting groove 8. Then, the connecting plate 6 can be pulled to remove it. The second screen 7 can be removed, and the same operation can be performed on the second mounting frame 15 to enlarge the screen hole. When the screen hole needs to be reduced, the connecting plate 6 can be positioned by the positioning mechanism, and the second screen 7 is inserted into the inner wall of the first hole 18 and the second hole 19. The mounting column 14 is moved by the reset mechanism, so that the mounting column 14 is inserted into the inner wall of the mounting groove 8, which can limit the installation of the connecting plate 6 and the second screen 7, thereby reducing the screen hole size. This eliminates the need for a motor during the adjustment of the screen hole, saving costs and resources, and does not occupy much space or affect the overall installation. It achieves the purpose of facilitating the adjustment of the screen hole, with a simple structure and easy use.

[0026] All electrical components mentioned in this article are connected to an external main controller and 220V AC mains power, and the main controller can be a conventional known device such as a computer that provides control.

[0027] In use: When using this adjustable metal screen, to enlarge the screen size, pull the sliding column 11 to move the moving plate 13. The moving plate 13 then moves the mounting column 14 away from the inner wall of the mounting groove 8. This allows the connecting plate 6 to be pulled off, and the second screen 7 to be removed. The same operation is performed on the second mounting frame 15 to enlarge the screen size. To decrease the screen size, insert the positioning block 5 on one side of the connecting plate 6 into the inner wall of the positioning groove 4 to position the connecting plate 6. Simultaneously, the second screen 7 is inserted... The spring 12 resets and drives the moving plate 13 to move within the inner walls of the first hole 18 and the second hole 19. The moving plate 13 then drives the mounting column 14 to move, so that the mounting column 14 is inserted into the inner wall of the mounting groove 8. This limits the installation of the connecting plate 6 and the second screen 7, thereby reducing the size of the screen holes. This eliminates the need for a motor during the adjustment of the screen holes, saving costs and resources. It also does not occupy much space and does not affect the overall installation. This achieves the goal of facilitating the adjustment of the screen holes. The structure is simple and easy to use.
