Description

Technical Field

[0001] This utility model relates to the field of dust control equipment technology, specifically a portable dust cover for welding workshops. Background Technology

[0002] Mobile welding workshop dust covers are highly efficient devices for collecting welding fumes. They are mainly used in welding operations in industrial production. Their core function is to be able to move flexibly to the welding site through their unique design, effectively absorbing and filtering the fumes generated during the welding process, thereby protecting the working environment and the health of workers.

[0003] Currently, some mobile welding workshop dust covers lack width adjustment functionality. The size and shape of the welding workpieces may vary depending on the project. If the width of the dust cover cannot be adjusted, it may not be able to tightly cover all workpieces or be flexibly adjusted to the optimal position to capture fumes, resulting in reduced purification efficiency. Furthermore, some mobile welding workshop dust covers do not have the function of retracting the casters. The bottom of the dust cover or the casters are in contact with the ground for a long time, especially when the dust cover is heavy or moves frequently, which may cause wear and tear on the ground, particularly when the workshop floor material is soft or uneven. At the same time, the dust cover is prone to movement under the action of external forces. Utility Model Content

[0004] The purpose of this invention is to provide a movable dust cover for welding workshops to solve the problems mentioned in the background art.

[0005] To achieve the above objectives, this utility model provides the following technical solution: a movable welding workshop dust cover, comprising a main body of the cover and a glass window disposed on one side of the surface of the main body of the cover, and further comprising:

[0006] A C-shaped plate is welded to one side of the surface of the protective cover body. The surface of the C-shaped plate is slidably connected to the inner cavity of the other side of the protective cover body. Fixing plates are bolted to both sides of the surface of the protective cover body. A transmission mechanism is provided on one side of the protective cover body.

Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0021] Please see Figure 1-4 As shown, a movable dust cover for a welding workshop includes two main body 1s. A glass window 2 is provided on one side of each main body 1, allowing easy observation of the interior. A C-shaped plate 3 is welded to one side of each main body 1, and the surface of the C-shaped plate 3 is slidably connected to the inner cavity of the other main body 1. The surface of the C-shaped plate 3 has a Z-shaped design, and the inner cavity of the other main body 1 also has a Z-shaped design. Fixing plates 4 are bolted to both sides of each main body 1. A transmission mechanism 5 is provided on one side of each main body 1, working in conjunction with that of the other main body 1. When the transmission mechanism 5 operates, it allows the other main body 1 to move. A mounting plate 6 is slidably connected to one side of the inner wall of the two protective cover bodies 1. When one side of the protective cover body 1 moves, the mounting plate 6 can extend or retract. The bottom of the mounting plate 6 is bolted with four movable wheels 7, which are evenly distributed on the four sides of the bottom of the mounting plate 6. A sliding groove 8 is opened on one side of the inner wall of the protective cover body 1. A sliding plate 9 is slidably connected to the inner wall of the sliding groove 8. One side of the surface of the sliding plate 9 is bolted to one side of the surface of the mounting plate 6. Under the action of the sliding plates 9 on both sides, the mounting plate 6 can move more stably. A lifting mechanism 10 is set inside the two protective cover bodies 1. The lifting mechanism 10 works in conjunction with the mounting plate 6. When the lifting mechanism 10 runs, the mounting plate 6 can be raised or lowered. When the mounting plate 6 is raised or lowered, it can drive the movable wheels 7 on the four sides to be raised or lowered.

[0022] The transmission mechanism 5 includes two torsion rods 51. One side of the surface of each torsion rod 51 is rotatably connected to the inner wall of the two fixed plates 4. A pulley 52 is bolted to one side of the surface of each torsion rod 51. When one torsion rod 51 rotates, it drives the pulley 52 on that side to rotate. A transmission belt 53 is driven to one side of the surface of each pulley 52. ​​When one pulley 52 rotates, it drives the transmission belt 53 to rotate. When the transmission belt 53 rotates, it drives the pulley 52 on the other side to rotate. When the pulley 52 on the other side rotates, it drives the pulley 52 on the other side to rotate. The screw rod 51 on the side rotates, and a one-way threaded rod 54 is bolted to one side of the surface of the screw rod 51. The other end of the surface of the one-way threaded rod 54 is rotatably connected to the surface of the fixed plate 4 on one side. When the screw rod 51 rotates, it can drive the one-way threaded rod 54 to rotate. A transmission plate 55 is threaded to one side of the surface of the one-way threaded rod 54. When the one-way threaded rod 54 rotates, it can drive the transmission plate 55 to move. One side of the surface of the transmission plate 55 is bolted to one side of the surface of the protective cover body 1 on one side. When the transmission plates 55 on both sides move, they can drive the protective cover body 1 on one side to move.

[0023] The lifting mechanism 10 includes a rotating rod 101. One side of the surface of the rotating rod 101 is rotatably connected to the surface of one side of the protective cover body 1. A transmission sleeve 102 is slidably connected to one side of the surface of the rotating rod 101. One side of the surface of the rotating rod 101 has a square design, and the inner wall of the transmission sleeve 102 also has a square design. When the rotating rod 101 rotates, it can drive the transmission sleeve 102 to rotate. A bevel gear 103 is bolted to one side of the surface of the rotating rod 101 and one side of the surface of the transmission sleeve 102. When the rotating rod 101 and the transmission sleeve rod 102 rotate, the bevel gears 103 on both sides can rotate. A lead screw 104 is bolted to one side of the surface of the bevel gear 103. When the bevel gear 103 rotates, the lead screw 104 can rotate. A threaded sleeve 105 is threadedly connected to the surface of the lead screw 104. The bottom of the threaded sleeve 105 is bolted to one side of the top of the mounting plate 6. When the lead screw 104 rotates, the threaded sleeve 105 can be raised or lowered. When the threaded sleeves 105 on both sides are raised or lowered, the mounting plate 6 can be raised or lowered.

[0024] Working principle: When the width of the workshop equipment changes, rotating one side of the toggle rod 51 drives the pulley 52 on one side to rotate. The pulley 52 then drives the transmission belt 53 to rotate. The transmission belt 53 then drives the pulley 52 on the other side to rotate the toggle rod 51 on the other side. The toggle rod 51 then drives the one-way threaded rod 54 to rotate. The one-way threaded rod 54 then moves the transmission plate 55. The movement of both transmission plates 55 then causes the protective cover body 1 on one side to slide along the surface of the C-shaped plate 3. When the protective cover body 1 moves to the appropriate position... When the protective cover body 1 is moved to a suitable position and stops, the rotating rod 101 is rotated. When the rotating rod 101 rotates, it can drive the transmission sleeve rod 102 to rotate. Then, the rotation of the rotating rod 101 and the transmission sleeve rod 102 can drive the bevel gears 103 on both sides to rotate. Next, the rotation of the bevel gears 103 can drive the lead screw 104 to rotate. When the lead screw 104 rotates, the threaded sleeve 105 can rise. Then, the rise of the threaded sleeves 105 on both sides can drive the mounting plate 6 to rise. Next, the rise of the mounting plate 6 can cause the four moving wheels 7 on all sides to rise. When the four moving wheels 7 on all sides rise to the maximum distance, they can enter the interior of the protective cover body 1.
