Description

Technical Field

[0001] This utility model relates to the field of high-temperature operation protection, specifically a high-temperature resistant arc screen bracket with an adjustable heat dissipation structure. Background Technology

[0002] High-temperature resistant arc face shield brackets are key devices used to fix protective face shields in arc operations. Their main function is to stably install the face shield on the operator's head or work equipment to isolate the human body from the arc light, high-temperature radiation, and metal spatter. In operations such as arc welding and plasma cutting, the temperature generated by the arc can reach thousands of degrees Celsius, accompanied by strong light radiation and molten metal spatter. Operators must be fully protected by face shields. If the bracket structure cannot effectively withstand the high temperature, it may cause the bracket to deform, the face shield to fall off, and lose its protective function. If there is no heat dissipation design, the accumulation of high temperature will accelerate the aging of the bracket material and may even burn the operator. Therefore, brackets with high-temperature resistance and heat dissipation functions are necessary equipment to ensure operational safety.

[0003] Traditional arc screen supports often use a single material for fixing, which exposes significant defects in high-temperature operations. On the one hand, the high-temperature resistance of traditional support materials is insufficient, and prolonged contact with the high temperature of the arc can easily cause softening and deformation, leading to screen displacement and failure of the protected area. On the other hand, traditional structures lack active heat dissipation design, relying solely on natural cooling, which allows heat to accumulate at the connection between the support and the screen. This not only shortens the lifespan of the support but also causes excessively high temperatures in the operator's head area, leading to discomfort such as stuffiness and fatigue, and affecting work efficiency. In addition, traditional supports have limited adjustment functions, making it difficult to adapt to the needs of operators of different heights or complex working postures, resulting in blind spots in the screen's protective field of view and increasing safety hazards. These problems not only reduce operational safety but also force operators to frequently replace supports or interrupt work, thereby affecting production efficiency and increasing protection costs. To address these issues, we propose a high-temperature resistant arc screen support with an adjustable heat dissipation structure. Utility Model Content

[0013] Compared with the prior art, this utility model provides a high-temperature resistant arc screen bracket with an adjustable heat dissipation structure, which has the following beneficial effects: 1. This high-temperature arc screen bracket with an adjustable heat dissipation structure utilizes an active heat dissipation system comprised of a cooling fan and fan mounting plate. This system forces airflow through the square groove on the side of the connecting sleeve to accelerate heat convection. Combined with a bracket body made of high-temperature resistant metal or engineering plastic, it maintains mechanical strength in high-temperature arc environments. Compared to traditional brackets that rely solely on natural cooling and are prone to softening, this significantly improves heat dissipation efficiency, prevents the screen from detaching, and reduces the risk of burns to operators. A motor component drives a lead screw to adjust the connecting rod's height. The rotational connection between the connecting sleeve and the fixed rod, along with the adjustment groove and adjustment seat's angle fine-tuning structure, allows for multi-dimensional adjustment of the screen's position. Compared to traditional fixed or single-adjustment brackets, this bracket can accommodate operators of different heights and complex working postures. For example, during high-altitude welding, it can quickly position the screen to the optimal protective angle, reducing blind spots, minimizing operator fatigue, and improving work efficiency. Its modular design allows for individual disassembly and replacement of the heat dissipation structure, resulting in lower maintenance costs compared to traditional integrated brackets. The mounting components can also integrate displays and other functional expansions. For example, parameters can be monitored in real time during industrial welding, and the fan can be easily replaced when it fails. The adjustment structure uses a threaded connection, which is not easy to loosen due to material expansion at high temperatures. The adjustment accuracy and reliability are higher than those of the traditional snap-fit ​​design. Attached Figure Description

When rotated, it drives lead screw sleeve 8 to rise and fall, adjusting the height of connecting rod 9; Screw sleeve 8: Screw sleeve 8 is threadedly connected to screw 7, and its top is rotatably connected to connecting rod 9, which converts the rotational motion of screw 7 into linear motion, thereby driving connecting rod 9 to rise and fall; Connecting rod 9: The bottom of the connecting rod 9 is rotatably connected to the lead screw sleeve 8, and the side is connected to the fixing rod 13 through the connecting sleeve 10. It rises and falls with the lead screw sleeve 8 to adjust the height of the face screen. Connecting sleeve 10: The connecting sleeve 10 is a hollow cylindrical structure with a bearing inside. The bottom is rotatably connected to the connecting rod 9, and the side is fixed to the fixing rod 13, so that the fixing rod 13 can rotate horizontally. Fan mounting plate 11: The fan mounting plate 11 is fixed to the top of the connecting sleeve 10. It has a hollow design, a sealing ring on the edge, and an oblong hole to adjust the angle of the cooling fan 12 and guide airflow for heat dissipation. Cooling fan 12: The cooling fan 12 is installed on the fan mounting plate 11. After starting, it forces air convection and dissipates heat through the square slot of the connecting sleeve 10, thereby reducing the temperature of the bracket. Fixing rod 13: One end of the fixing rod 13 is fixed to the connecting sleeve 10, and the other end is equipped with the mounting plate 14. It can rotate horizontally and is used to install the front screen and display screen structure. Mounting plate 14: Mounting plate 14 is L-shaped and fixed to fixing rod 13.

Adjustment slot 15: The adjustment slot 15 is opened on the side of the mounting plate 14, and the adjustment seat 16 is installed inside. It is locked in position with the fastening nut 17 to realize the fine adjustment of the screen angle. Adjustment seat 16: The adjustment seat 16 is movably placed in the adjustment groove 15, and the end is connected to the fastening nut 17. It can move and rotate in the groove and is used to install the display screen housing 18.

After the motor 3 starts, its output shaft passes through the side wall of the gearbox 4, driving gear 5 to rotate. Gear 5 and gear 6 mesh vertically to form a transmission structure. Through the meshing of the teeth inside the gearbox 4, the horizontal rotation of the motor 3 is converted into the vertical rotation of gear 6, ensuring stable power transmission and adapting to high-temperature working environments. Gear 6 is internally connected to a lead screw 7. When gear 6 rotates, the lead screw 7 rotates synchronously. The lead screw 7 is connected to a lead screw sleeve 8 via a thread, converting the rotational motion into the vertical lifting motion of the lead screw sleeve 8. The top of the lead screw sleeve 8 is rotatably connected to a connecting rod 9, driving the connecting rod 9 to move up and down within a range of 15-20cm, achieving precise adjustment of the faceplate height to meet various needs. To accommodate the height requirements of operators or workbenches, the horizontal rotation of the connecting sleeve and the fixed rod is adjustable. The side of the connecting rod 9 is connected to the fixed rod 13 via the connecting sleeve 10. The bottom of the connecting sleeve 10 is rotatably connected to the connecting rod 9, allowing the fixed rod 13 to rotate left and right in the horizontal direction. When the operator manually rotates the fixed rod 13, the rotation axis of the connecting sleeve 10 provides rotational freedom. The internal damping structure maintains positioning stability and prevents angular deviation caused by operational vibration. An mounting plate 14 is installed on the other side of the fixed rod 13, and an adjustment seat 16 is embedded in the side adjustment groove 15. The end of the adjustment seat 16 is fixed by a fastening nut 17. After loosening the fastening nut 17, the adjustment seat 16 can slide up and down or rotate slightly within the adjustment groove 15, achieving pitch adjustment of the face shield within a range of ±30°. The joint, in conjunction with the horizontal rotation of the fixing rod 13, covers the protection angle requirements of different working positions such as overhead welding and downward welding. The top of the connecting sleeve 10 is fixed with a fan mounting plate 11, and a cooling fan 12 is embedded in the square groove on its side. After the fan 12 is started, forced air is drawn in from the square groove on the side of the connecting sleeve 10. When it flows through the inside of the connecting sleeve 10, it absorbs the heat conducted by the bracket and is then discharged through the fan 12. This can control the surface temperature of the bracket below 50°C, avoiding the problem of high temperature accumulation above 80°C in traditional brackets. The main body of the bracket is made of high temperature resistant metal or engineering plastics such as PEEK. When the arc heat is conducted to the connecting rod 9 and the connecting sleeve 10, the high thermal conductivity material quickly transfers the heat to the vicinity of the cooling fan 12. The fan 12 drives the airflow to accelerate thermal convection. At the same time, the side of the connecting sleeve 10... The groove increases the heat dissipation area, enhances heat dissipation, and prevents the connection between the screen and the bracket from aging and deforming due to high temperatures. The fixing rod 13 is connected to the adjustment structure through the mounting plate 14. The sliding and locking of the adjustment seat 16 within the adjustment groove 15 allows for flexible adjustment of the display screen structure's position. Operators can adjust the display screen 19 to eye level to view operating parameters in real time, reducing the need to look down or up, and lowering operator fatigue. The display screen housing 18 is fixed to the side of the adjustment seat 16. The internal display screen 19 integrates a temperature sensor and control circuit, displaying the bracket temperature and fan 12 operating status in real time. When the cooling fan 12 malfunctions or the bracket temperature is too high, the display screen 19 issues an alarm, allowing operators to promptly remove the fan mounting plate 11 to replace the fan 12, completing the repair within 3 minutes.Compared to traditional integrated brackets, this significantly reduces maintenance costs and downtime.
