Description

Technical Field

[0001] This application relates to the technical field of welding protection equipment, and in particular to a spatter protection device for weld spatter. Background Technology

[0002] During welding operations, the high-temperature molten metal generates a large amount of spatter. This spatter not only pollutes the working environment but also poses a threat to the safety of operators and can disrupt the normal operation of surrounding equipment. Existing welding protection devices are typically of fixed dimensions, making it difficult to flexibly adjust them to accommodate varying lengths of protective space. When welding workpieces of different sizes, either the protection range is insufficient to effectively block spatter, or the protective device is too large, resulting in wasted space and operational inconvenience, thus reducing the protective effect and compromising the safety of the welding operation.

[0003] A search revealed Chinese Patent Publication No. CN105299430A, which discloses a protective fence for welding. The fence includes a rectangular frame structure with an open rear. This frame structure consists of two main beams vertically fixed to the ground and four walls located in front of the main beams. The surface of the frame structure is coated with a high-temperature resistant and corrosion-resistant layer. Mounting seats are welded to the bottom of the main beams, which are then fixed to the ground by bolts passing through the mounting seats. The four walls are open at the bottom and rear, formed by two side walls, a top wall, and a front wall. A ventilation hole is located in the middle of the top wall, and an exhaust fan is installed at the ventilation hole. A lighting fixture is installed at the bottom of the top wall, and a welding machine rack is installed at one end of the top wall. Racking racks are installed on the inner sides of the two side walls, and a toolbox is installed in the middle of the inner side of one of the side walls.

[0004] Regarding the aforementioned related technologies, the inventors have discovered the following drawbacks: existing weld overlay protection devices cannot adapt to different site specifications, resulting in poor versatility. To address the problems of insufficient protection range, wasted space, and poor versatility caused by the fixed dimensions of existing weld overlay protection devices, this application improves upon these issues by modifying the sliding connection of the left and right protective plates, the angle adjustment mechanism, and the locking mechanism. This achieves the technical effect of flexible adjustment of the protection length and angle, secure locking, and effective blocking of spatter. Utility Model Content

[0005] To improve the versatility of protective devices, this application provides a spatter-proof welding protection device.

[0006] This application provides a spatter-proof welding protection device, employing the following technical solution: It includes a left protective plate and a right protective plate. The left protective plate has a first sliding groove, through which it is slidably connected to the right protective plate. Both the left and right protective plates are equipped with an angle adjustment mechanism and a locking mechanism. The angle adjustment mechanism includes a first protective plate rotatably connected to the left protective plate and a second protective plate rotatably connected to the right protective plate. The locking mechanism includes a second sliding groove on the right protective plate, within which a locking plate is vertically slidably connected, and a locking block is provided in the first sliding groove. The angle adjustment mechanism adapts to different working heights. After length adjustment, the locking mechanism locks the left and right protective plates.

[0007] Optionally, the locking plate is provided with multiple locking blocks, and a locking space is formed between every two locking blocks.

[0008] Optionally, a foot pedal is provided on the side of the locking plate, and a passage groove is provided on the groove wall of the second sliding groove.

[0009] Optionally, a spring rod is provided on the lower end face of the locking plate, and a spring cylinder adapted to the spring rod is provided on the bottom wall of the second sliding groove; a compression spring is provided between the lower end face of the spring rod and the bottom wall of the spring cylinder.

[0010] Optionally, a third sliding groove is provided on the first protective plate, and the specifications of the third sliding groove are adapted to the specifications of the second protective plate.

[0011] Optionally, the first protective plate is provided with a first rotating shaft, and the first protective plate is slidably connected to the left protective plate through the first rotating shaft; the second protective plate is provided with a second rotating shaft, and the second protective plate is rotatably connected to the right protective plate through the second rotating shaft.

[0012] Optionally, a fourth sliding groove is provided on the third sliding groove, and a fourth sliding block adapted to the fourth sliding groove is provided on the second protective plate.

[0013] Optionally, a worm gear is rotatably connected to the left protective plate, and a worm wheel adapted to the worm gear is coaxially fixed on the first rotating shaft.

[0014] Optionally, the worm gear is coaxially fixedly provided with a first bevel gear; the left protective plate is rotatably connected to a third rotating rod, one end of which is provided with a second bevel gear that meshes with the first bevel gear, and the other end of which is provided with a third bevel gear.

[0015] Optionally, a fourth rotating rod is rotatably connected to the left protective plate, and a fourth bevel gear that meshes with the third bevel gear is coaxially fixed on the fourth rotating rod.

[0016] In summary, this application includes the following beneficial technical effects:

[0017] 1. This utility model utilizes a left protective plate that is slidably connected to a right protective plate via a first sliding groove. The operator can adjust the relative positions of the left and right protective plates by sliding the right protective plate according to the length of the space to be protected, thereby covering the required protection area. This effectively solves the problem of insufficient protection range or wasted space in existing fixed-size protective devices, and improves the adaptability of the device to welding operations on workpieces of different specifications. Through a transmission structure such as a worm gear, worm wheel, and bevel gear, rotating the fourth rotating rod can drive the first and second protective plates to rotate, adapting to working conditions at different heights. Simultaneously, the self-locking characteristics of the worm wheel and worm gear ensure that the protective plates remain stable after angle adjustment, preventing changes in angle due to external forces and ensuring the reliability of the protective effect.

[0018] 2. The locking plate of this utility model achieves engagement and disengagement with the locking block through a foot pedal, a spring rod, and a compression spring. When adjusting the position of the right protective plate, pressing the foot pedal compresses the spring, disengaging the locking space from the locking block. After pushing the right protective plate to the appropriate position, releasing the foot pedal causes the compression spring to drive the locking plate upward, limiting the locking block and achieving a secure lock between the left and right protective plates, preventing accidental slippage during operation.

[0027] The following is in conjunction with the appendix Figures 1-7 This application will be further described in detail below. The technical solutions in the embodiments of this application will be clearly described with reference to the accompanying drawings. Obviously, the described embodiments are only some, not all, of the embodiments of this application. All other embodiments obtained by those skilled in the art based on the embodiments of this application are within the scope of protection of this application.

[0028] This application discloses a protective device for preventing spatter during welding. For example... Figure 1 As shown, it includes a left protective plate 1 and a right protective plate 2. The left protective plate 1 has a first sliding groove 3, and the left protective plate 1 is slidably connected to the right protective plate 2 through the first sliding groove 3. Both the left protective plate 1 and the right protective plate 2 are provided with an angle adjustment mechanism and a locking mechanism. The angle adjustment mechanism includes a first protective plate 4 rotatably connected to the left protective plate 1 and a second protective plate 5 rotatably connected to the right protective plate 2. The locking mechanism includes a second sliding groove 6 opened on the right protective plate 2, a locking plate 7 vertically slidably connected in the second sliding groove 6, and a locking block 8 provided in the first sliding groove 3.

[0029] In this embodiment, when splash protection is required, the left protective plate 1 is first fixed. After the right protective plate 2 is moved to the corresponding position by the telescopic design of the left protective plate 1 and the right protective plate 2, the left protective plate 1 and the right protective plate 2 are locked by the locking mechanism to prevent accidental sliding during operation, which would affect the splash protection effect. The angle adjustment mechanism allows the left protective plate 1 and the right protective plate 2 to adapt to working conditions at different heights.

[0030] Please see Figure 5 The locking plate 7 is provided with multiple locking blocks 9, and a locking space is formed between every two locking blocks 9; a foot pedal 10 is provided on the side of the locking plate 7, and a passage groove is opened in the groove wall of the second sliding groove 6; a spring rod 11 is provided on the lower end face of the locking plate 7, and a spring cylinder adapted to the spring rod 11 is provided on the bottom wall of the second sliding groove 6; a compression spring is provided between the lower end face of the spring rod 11 and the bottom wall of the spring cylinder.

[0031] In this embodiment, when the position of the right protective plate 2 needs to be adjusted, the operator steps on the foot pedal 10, causing the locking plate 7 to move downward, compressing the compression spring, and disengaging the locking space from the locking block 8. The operator pushes the right protective plate 2, and when the right protective plate 2 reaches the appropriate position, the operator stops stepping on the foot pedal 10. The elastic restoring force of the compression spring drives the locking plate 7 to rise through the spring rod 11, causing the locking block 8 to reposition itself within the locking space. The locking blocks 9 on both sides of the locking block 8 limit the locking block 8, thereby locking the left protective plate 1 and the right protective plate 2.

[0032] Please see Figure 1 The first protective plate 4 has a third sliding groove 12, the specifications of which are compatible with the specifications of the second protective plate 5; the first protective plate 4 has a first rotating shaft 13, which is slidably connected to the left protective plate 1; the second protective plate 5 has a second rotating shaft 14, which is rotatably connected to the right protective plate 2; the third sliding groove 12 has a fourth sliding groove 15, and the second protective plate 5 has a fourth sliding block 16 that is compatible with the fourth sliding groove 15;

[0033] In this embodiment, the first protective plate 4 is slidably connected to the second protective plate 5 through the third sliding groove 12, so that the second protective plate 5 can move with the right protective plate 2; the first protective plate 4 is slidably connected to the left protective plate 1 through the first rotating shaft 13, and the second protective plate 5 is rotatably connected to the right protective plate 2 through the second rotating shaft 14; by rotating the first rotating shaft 13, the first protective plate 4 can drive the second protective plate 5 to rotate around the axis of the first rotating shaft 13, thereby adapting to working conditions at different heights.

[0034] Please see Figure 3 A worm gear 17 is rotatably connected to the left protective plate 1. A worm wheel 18, adapted to the worm gear 17, is coaxially fixed on the first rotating shaft 13. A first bevel gear is coaxially fixed on the worm gear 17. A third rotating rod 19 is rotatably connected to the left protective plate 1. A second bevel gear meshing with the first bevel gear is provided at one end of the third rotating rod 19, and a third bevel gear is provided at the other end. A fourth rotating rod 20 is rotatably connected to the left protective plate 1. A fourth bevel gear meshing with the third bevel gear is coaxially fixed on the fourth rotating rod 20.

[0035] In this embodiment, the fourth rotating rod 20 drives the third rotating rod 19 to rotate via the fourth bevel gear and the third bevel gear; the third rotating rod 19 can drive the worm gear 17 to rotate via the second bevel gear and the first bevel gear, and the worm gear 17 drives the first rotating shaft 13 to rotate via the worm wheel 18, thereby adjusting the angle of the first protective plate 4 and the second protective plate 5; the self-locking characteristic of the worm wheel 18 and the worm gear 17 enables the first protective plate 4 and the second protective plate 5 to be maintained after the angle is adjusted.

[0036] The implementation principle of the anti-splatter welding protection device in this application embodiment is as follows:

[0037] Fix the left protective plate 1 in a suitable position as the reference of the device; according to the length of the space to be protected, slide the right protective plate 2 through the first sliding groove 3 on the left protective plate 1 to adjust the relative position of the left and right protective plates 2 to cover the required protection area.

[0038] The operator steps on the foot pedal 10 on the side of the locking plate 7; at this time, the locking plate 7 slides down in the second sliding groove 6, compressing the compression spring below the spring rod 11, so that the locking space on the locking plate 7 disengages from the locking block 8 in the first sliding groove 3; then the operator moves the right protective plate 2.

[0039] When the right protective plate 2 moves to the target position, release the foot pedal 10. The elastic restoring force of the compressed spring pushes the spring rod 11, causing the locking plate 7 to rise. The locking block 8 falls back into the locking space. The locking block 8 is limited by the latch 9, so that the left and right protective plates 2 are locked in the length direction to prevent accidental sliding during operation.

[0040] If the height or angle of the protective plate needs to be adjusted, rotate the fourth rotating rod 20. The fourth rotating rod 20 drives the third rotating rod 19 to rotate through the fourth bevel gear and the third bevel gear. The third rotating rod 19 can drive the worm gear 17 to rotate through the second bevel gear and the first bevel gear. The worm gear 17 drives the first rotating shaft 13 to rotate through the worm wheel 18. Since the first protective plate 4 and the second protective plate 5 are slidably connected through the third sliding groove 12, the fourth sliding groove 15 and the fourth sliding block 16, the rotation of the first protective plate 4 will drive the second protective plate 5 to rotate synchronously, thereby adjusting the angle of the two to adapt to welding operation scenarios of different heights. Utilizing the self-locking characteristics of the worm wheel 18 and the worm gear 17, the position of the protective plate can be kept stable after the angle adjustment is completed, avoiding changes in angle due to external forces.

[0041] After adjustment, the left protective plate 1, right protective plate 2, first protective plate 4 and second protective plate 5, together with the on-site equipment, form a closed or semi-closed protective area to block high-temperature metal spatter generated during the welding process, protecting the safety of operators and the normal operation of surrounding equipment.

[0042] The above are all preferred embodiments of this application, and are not intended to limit the scope of protection of this application. Therefore, all equivalent changes made in accordance with the structure, shape and principle of this application should be covered within the scope of protection of this application.
