Description

Technical Field

[0001] This utility model relates to the field of metal screen technology, and more specifically, to a metal screen with an adjustable tilt angle. Background Technology

[0002] Sparks and metal particles ejected during electric welding operations pose a certain danger, potentially causing fires, explosions, and other accidents. This is particularly true in the welding and maintenance of production equipment in chemical and food processing enterprises, where the presence of flammable and explosive substances in the work environment makes the isolation and protection of welding spatter extremely important. Currently, enterprises employ long-distance isolation methods for welding operations, which involves setting up welding sites away from flammable and explosive equipment, devices, pipelines, and storage tanks to prevent explosions caused by welding spatter. However, for large production equipment, which is highly integrated into the production workshop, maintenance work must be carried out within the workshop or even inside the equipment, making long-distance isolation methods impractical. In such cases, metal screens are used to isolate welding spatter. In practice, we have observed that tilted screens are more effective at isolating welding spatter, allowing it to fall to the ground more quickly upon impact with the tilted screen, thus dissipating its high temperature. Furthermore, existing related screens occupy a large amount of space and are inconvenient to store. To address these issues, we have introduced the following device. Utility Model Content

[0026] Example:

[0027] The following is in conjunction with the appendix Figure 1-4 The present invention will be described in further detail below.

[0028] Please see Figure 1-4 This utility model provides a technical solution: an adjustable tilt angle metal screen, including a base 1, a support block 2, and a main screen 3. The support block 2 is fixedly connected to the upper surface of the base 1. The base 1 is rotatably connected to the main screen 3 via a pin. A first connecting seat 4 is fixedly connected to the surface of the main screen 3. A push rod 5 is rotatably connected to the first connecting seat 4 via a pin. The other end of the push rod 5 is rotatably connected to a second connecting seat 6 via a pin. A U-shaped seat 7 is fixedly connected to the upper surface of the base 1. A first bearing 8 passes through the surface of the U-shaped seat 7. A first rotating shaft 9 passes through the first bearing 8. A crank 10 is fixedly connected to one end of the first rotating shaft 9. A threaded column 11 is fixedly connected to the other end of the first rotating shaft 9.

The second connecting seat 6 is fixedly connected to the surface of the threaded tube 14.

[0029] By adopting the above technical solution, this adjustable tilt angle metal screen, through the setting of a crank handle 10, a threaded column 11, a threaded tube 14, and a push rod 5, allows people to adjust the tilt angle of the screen by first turning the crank handle 10, which drives the threaded column 11 to rotate. With the cooperation of the threaded column 11 and the threaded tube 14, the threaded tube 14 moves and drives one end of the push rod 5, causing the other end of the push rod 5 to drive the main screen 3 to rotate. After the tilt angle of the main screen 3 reaches the expected state, turning the crank handle 10 stops, making it convenient for people to adjust the tilt angle of the screen.

[0030] Specifically, the main screen 3 has a storage slot 15 on its surface, a first auxiliary screen 16 and a second auxiliary screen 17 slidably connected to the storage slot 15, a limiting slot 18 on its surface, a first movable block 19 slidably connected to the limiting slot 18, a first rack 20 fixedly connected to the surface of the first movable block 19, a first clearance slot 21 on the surface of the first movable block 19, a second movable block 22 slidably connected to the limiting slot 18, a second rack 23 fixedly connected to the surface of the second movable block 22 corresponding to the position of the first clearance slot 21, a second clearance slot 24 on the surface of the second movable block 22 corresponding to the position of the first rack 20, a mounting block 25 fixedly connected to the surface of the main screen 3, a brake motor 26 fixedly connected to the upper surface of the mounting block 25, a gear 27 fixedly connected to the other end of the output shaft of the brake motor 26, the gear 27 meshing with the first rack 20 and the second rack 23.

[0031] By adopting the above technical solution, the adjustable tilt angle metal screen, through the setting of a brake motor 26, gear 27, first rack 20 and second rack 23, allows people to control the operation of the brake motor 26 through the controller 30 when storing the device, thereby driving the gear 27 to rotate. The gear 27 interacts with the first rack 20 and the second rack 23 respectively, so that the first rack 20 drives the first movable block 19 and the first sub-screen 16 to move, and the second rack 23 drives the second movable block 22 and the second sub-screen 17 to move, so that the first sub-screen 16 and the second sub-screen 17 enter the storage slot 15 simultaneously, thereby reducing the overall size of the screen and making it easier for people to store the device.

[0032] Specifically, there are two sets of support blocks 2, which are symmetrically arranged on the upper surface of the base 1.

[0033] Specifically, the base 1 has an energy storage compartment 28 inside, and a battery 29 is fixedly connected in the energy storage compartment 28.

[0037] The working principle of this utility model is as follows: During use, the presence of the bottom wheel assembly 31 and brake pads 32 makes the movement and installation of this device relatively convenient. After installation, the controller 30 controls the brake motor 26 to extend the first and second sub-screens 16 and 17 from the storage slot 15. Then, the tilt angle of the screens is adjusted by turning the crank handle 10, which in turn rotates the threaded column 11. With the cooperation of the threaded column 11 and the threaded tube 14, the threaded tube 14 moves and drives one end of the push rod 5, causing the other end of the push rod 5 to rotate the main screen 3, thus tilting the main screen 3. Once the desired angle is reached, stop turning the crank handle 10, and welding can begin. After welding is completed, the controller 30 controls the brake motor 26 to operate, which in turn drives the gear 27 to rotate. The gear 27 interacts with the first rack 20 and the second rack 23, causing the first rack 20 to move the first movable block 19 and the first sub-screen 16, and the second rack 23 to move the second movable block 22 and the second sub-screen 17. Thus, the first sub-screen 16 and the second sub-screen 17 enter the storage slot 15 simultaneously, thereby reducing the overall size of the screen and making it easier to store the device.
