Description

Technical Field

[0001] This utility model relates to the field of welding machine technology, specifically a welding machine with a sliding protective structure. Background Technology

[0002] In the field of welding equipment, the heat generated during welding machine operation needs to be dissipated promptly through heat dissipation vents on the casing to ensure the normal operation of internal electrical components. Currently, most welding machines use heat dissipation vents on the side walls of the casing (such as the left and right side panels), combined with internal air ducts and heat dissipation fins, to effectively improve heat dissipation efficiency. However, when the welding machine is idle, in transport, or not in operation, the long-term exposed heat dissipation vents lack effective protection, making it easy for dust, welding slag particles, metal shavings, and other debris to enter the equipment. These debris may not only accumulate on the surface of circuit boards and heat dissipation fins, affecting normal circuit operation, but may also block air ducts, reducing heat dissipation performance during subsequent use, or even causing short circuits and other malfunctions, significantly shortening the service life of the welding machine.

[0003] In existing technologies, some welding machines protect their heat dissipation vents by adding filters, but these can only filter out fine dust and cannot block larger particles. Some welding machines use removable baffles to cover the heat dissipation vents, but this is cumbersome, requiring tools for removal, and repeated disassembly and reassembly can easily damage the baffles or the connecting structure of the outer casing. Other welding machines lack any dustproof measures, leaving the equipment completely exposed to a dusty environment when not in use, significantly increasing maintenance costs and the risk of failure. Therefore, there is an urgent need for a simple, easy-to-operate protective structure that can both ensure the heat dissipation needs of the welding machine during operation and effectively seal the heat dissipation vents and isolate dust and debris when idle. Utility Model Content

[0004] To overcome the shortcomings mentioned above, this utility model aims to provide a technical solution that can solve the above problems.

[0005] A welding machine with a sliding protective structure includes a main body shell, wherein the left and right sides of the main body shell are respectively provided with flow-guiding heat dissipation fins that communicate with the internal air duct, and the surface of the flow-guiding heat dissipation fins is provided with a nano-hydrophobic coating.

[0006] Corresponding to the position of the flow-guiding heat dissipation fins, the main body shell is provided with a slot, and a sliding door that can slide in the left and right direction is arranged in the slot. When the sliding door is slid to the leftmost position, the position of the flow-guiding heat dissipation fins is closed. When the sliding door is slid to the rightmost position, the position of the flow-guiding heat dissipation fins is opened.

[0007] The leftmost and rightmost sides of the slot are respectively provided with first magnetic strips, and the left and right sides of the sliding door are respectively provided with second magnetic strips that are compatible with the first magnetic strips. Through the adsorption and cooperation of the first magnetic strips and the second magnetic strips, the sliding door can be fixed to the position of the flow-guiding heat dissipation fins when it is closed or opened.

[0008] As a further embodiment of this utility model: the heat dissipation fins are made of metal and are arranged in an array on the left and right side walls of the main body shell.

[0009] As a further embodiment of this invention: the nano-hydrophobic coating is a fluoropolymer coating that uniformly covers the outer surface of the flow-guiding heat dissipation fins.

[0010] As a further embodiment of this utility model: the groove is a protective sliding cavity integrally formed with the main body shell, the protective sliding cavity has a ventilation opening in the area corresponding to the flow-guiding heat dissipation fins, the upper and lower inner walls of the protective sliding cavity are provided with guide rails for guiding the sliding door to slide, and the upper and lower side edges of the sliding door slide in cooperation with the guide rails;

[0011] When the sliding door is slid to the closed position of the corresponding airflow-guiding heat dissipation fin, it blocks the ventilation opening; when it is slid to the open position of the corresponding airflow-guiding heat dissipation fin, it exposes the ventilation opening, allowing the airflow-guiding heat dissipation fin to communicate with the outside air.

[0012] As a further embodiment of this utility model: the first magnetic strip and the second magnetic strip have opposite polarities, and when the sliding door slides to the left or right limit position of the protective sliding cavity, the first magnetic strip and the second magnetic strip are attracted and fixed.

[0013] As a further embodiment of this utility model: handles are provided on both the left and right surfaces of the sliding door.

[0014] As a further embodiment of this utility model: the guide rail extends in the left and right direction along the protective sliding cavity, and the upper and lower edges of the sliding door are respectively embedded in the guide rail and can slide along the guide rail.

[0015] Compared with the prior art, the beneficial effects of this utility model are as follows:

[0016] This invention features a sliding door that can move left and right, along with a magnetic fixing structure. When the welding machine is idle, the door can slide to the closed position and be fixed in place by the first and second magnetic strips, effectively preventing dust, welding slag, and other debris from entering the interior and protecting the heat dissipation fins and internal components of the welding machine. When the welding machine is working, the door slides to the open position, exposing the ventilation opening and ensuring that the heat dissipation fins are fully connected to the outside air, thus ensuring heat dissipation efficiency. The nano-hydrophobic coating prevents coolant and welding slag from adhering to the surface of the heat dissipation fins, further improving heat dissipation performance.

[0024] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. 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.

[0025] Please see Figure 1-3 In this embodiment of the invention, a welding machine with a sliding protective structure includes a main body shell 1. The left and right sides of the main body shell 1 are respectively provided with flow-guiding heat dissipation fins 2 that communicate with the internal air duct. The flow-guiding heat dissipation fins 2 are used to dissipate the heat generated during the operation of the welding machine, thereby ensuring the normal operation of the internal electrical components. The surface of the flow-guiding heat dissipation fins 2 is coated with a nano-hydrophobic coating, which is a fluoropolymer coating. This coating evenly covers the outer surface of the flow-guiding heat dissipation fins 2, effectively preventing coolant, welding slag, and other liquids and impurities from adhering to the fin surface, avoiding fin blockage, and thus ensuring heat dissipation efficiency.

[0026] Corresponding to the position of the heat dissipation fins 2, the main body shell 1 is provided with a protective sliding cavity 6 integrally formed with the main body shell 1. This protective sliding cavity 6 is used to accommodate the sliding door 3, which can slide left and right, and to guide and protect it. Ventilation openings 7 are formed in the area of ​​the protective sliding cavity 6 corresponding to the heat dissipation fins 2. The shape of the ventilation openings 7 can be rectangular or elliptical, and the area of ​​the ventilation openings 7 is not less than 80% of the projected area of ​​the heat dissipation fins 2 on the side wall of the main body shell 1, to ensure the heat dissipation effect during welding machine operation. The upper and lower inner walls of the protective sliding cavity 6 are provided with guide rails 9 extending in the left and right direction. The cross-section of the guide rails 9 can be "C" shaped, "L" shaped, or other shapes. The upper and lower side edges of the sliding door 3 are embedded in the guide rails 9 and form a clearance fit with the guide rails 9, allowing the sliding door 3 to slide smoothly left and right along the guide rails 9.

[0027] The sliding door 3 is a plate-like structure that can slide left and right. It can be made of transparent or semi-transparent high-temperature resistant engineering plastic with a thickness between 2-5mm. The surface of the sliding door 3 has an anti-slip texture for easy pushing and pulling by the operator. When the sliding door 3 slides to the far left, it blocks the ventilation opening 7 of the protective sliding cavity 6, effectively sealing the position of the heat dissipation fins 2 and preventing dust, welding slag, and other debris from entering the welding machine. When the sliding door 3 slides to the far right, the ventilation opening 7 is fully exposed, and the heat dissipation fins 2 are connected to the outside air through the ventilation opening 7, ensuring the welding machine's heat dissipation needs are met.

[0028] To secure the sliding door 3 in its closed or open position, first magnetic strips 4 are respectively installed on the leftmost and rightmost sides of the protective sliding cavity 6. Second magnetic strips 5, compatible with the first magnetic strips 4, are respectively installed on the left and right sides of the sliding door 3. The polarities of the first magnetic strips 4 and the second magnetic strips 5 are opposite. When the sliding door 3 slides to its left or right limit position in the protective sliding cavity 6, the first magnetic strips 4 and the second magnetic strips 5 attract each other using the principle of opposite poles attracting, firmly securing the sliding door 3 and preventing it from shifting due to vibration or other factors, thus effectively ensuring the stability of the closed or open state. Furthermore, handles 8 are provided on both the left and right surfaces of the sliding door 3, allowing operators to more easily push the sliding door 3 to open and close the ventilation vents.

[0029] The heat dissipation fins 2, made of metal, are arrayed on the left and right side walls of the main body shell 1, forming an effective heat dissipation channel through connection with the internal air duct. During the operation of the welding machine, heat is transferred to the surface of the main body shell 1 through the heat dissipation fins 2, and then exchanged with the outside air through the ventilation vents 7. When the welding machine is idle or in transport, the sliding door 3 slides to the closed position, and with the nano-hydrophobic coating, double protection prevents foreign objects from entering, ensuring the safety of the internal structure of the welding machine.

[0030] In summary, this utility model, by setting a sliding door 3 that can slide left and right and a magnetic fixing structure, allows the door 3 to slide to the closed position when the welding machine is idle. This, combined with the first magnetic strip 4 and the second magnetic strip 5, effectively prevents dust, welding slag, and other debris from entering the interior, protecting the heat dissipation fins 2 and the internal components of the welding machine. When the welding machine is working, the door 3 slides to the open position, exposing the ventilation opening 7, ensuring that the heat dissipation fins 2 are fully connected to the outside air, thus guaranteeing heat dissipation efficiency. The nano-hydrophobic coating prevents coolant and welding slag from adhering to the surface of the heat dissipation fins, further improving heat dissipation performance.

[0031] It will be apparent to those skilled in the art that this invention is not limited to the details of the exemplary embodiments described above, and that it can be implemented in other specific forms without departing from the spirit or essential characteristics of this invention. Therefore, the embodiments should be considered exemplary and non-limiting in all respects, and the scope of this invention is defined by the appended claims rather than the foregoing description. Thus, it is intended that all variations falling within the meaning and scope of equivalents of the claims be included within this invention.
