Description
Technical Field
[0001] This utility model relates to the field of welding machine protective sheds, specifically a protective device for a manual arc welding machine. Background Technology
[0002] Welding machine protective sheds are key facilities for ensuring the safety of welding machines and operators on construction sites. They are made of sturdy steel structures and are rainproof, sunproof, and windproof, effectively isolating the welding machine from the external environment and extending its service life. The bottom of the protective shed is equipped with rollers for easy and quick transport to different work locations, and it is equipped with a dedicated power distribution box and fire-fighting equipment to ensure electrical and fire safety.
[0003] Traditional manual arc welding machines utilize protective canopies for shielding and protection, effectively reducing damage from rain and impacts and extending their lifespan. However, a problem exists in practical use: the welding machine requires a longer power cord to adapt to different usage scenarios and environments. Traditionally, the power cord is coiled on one side of the protective canopy and protrudes from it, which undoubtedly increases the size of the canopy and affects its ease of transport and accessibility. Therefore, the inventor urgently needs to design a storage structure that can effectively accommodate longer power cords, thereby significantly improving the transport convenience and accessibility of the protective canopy. Utility Model Content
[0004] Based on this, the purpose of this utility model is to provide a protective device for a manual arc welding machine to solve the technical problem that welding machines require long power cords due to different usage scenarios, and that traditional power cords are wound up on one side of the protective canopy and protrude, resulting in an increased size of the protective canopy and reduced ease of movement and passage.
[0005] To achieve the above objectives, the present invention provides the following technical solution: a protective device for a manual arc welding machine, comprising a protective frame body, a placement plate movably disposed on the front side of the protective frame body, a slot formed on the upper front side of the protective frame body, and sliding grooves provided on the upper sides of both sides of the interior of the protective frame body. The two sides of the placement plate are slidably connected by a slider and the sliding grooves, and can be stored inside the upper interior of the protective frame body through the slots.
[0006] By adopting the above technical solution, the sliding connection between the main body of the protective frame and the movable placement plate realizes the integration of the power cord storage function. The placement plate can be completely stored inside the upper part of the main body of the protective frame through the cooperation of the slider and the groove, which significantly reduces the space occupation problem caused by the traditional exposed power cord and makes the overall size of the protective shed more compact.
[0007] Furthermore, the surface of the placement plate is fixed with several hooks, which are in an "L" shape, and the power cord is placed on the surface of the placement plate by wrapping around the hooks.
[0008] By adopting the above technical solution, power cords can be layered or zoned for winding and fixing, effectively avoiding the problems of cable tangling and scattering caused by traditional random stacking, improving the standardization of on-site operations. At the same time, the arrangement of hooks supports the classified management of multiple power cords, and the target line can be quickly located when needed, shortening preparation time.
[0009] Furthermore, two snap-fit pieces are fixed on one side of the placement plate near the main body of the protective frame. When the placement plate is in the stored state, the placement plate is snapped into and limited by the snap-fit pieces to limit the position of the placement plate.
[0010] By adopting the above technical solution, the absolute stability of the placement board in the storage state is ensured. Even if the protective shed moves on a bumpy road, the locking structure can prevent the placement board from accidentally sliding out and avoid the power cord from falling out again. At the same time, the limiting mechanism simplifies the operation process. No additional fixing tools are needed when storing it. Simply push in the locking mechanism to lock it, which improves the operation efficiency.
[0011] Furthermore, the slider has a circular cross-section, allowing it to slide and rotate inside the groove, and the placement plate is made of wood.
[0012] By adopting the above technical solution, it can have both sliding and rotating functions in the chute, realizing a smooth transition of the placement plate from a vertical to a horizontal state. This dual-degree-of-freedom motion characteristic allows operators to quickly adjust the posture of the placement plate without disassembly, significantly reducing the complexity of storage operations.
[0013] Furthermore, four sets of lifting lugs are installed on both sides of the main body of the protective frame, and casters are installed at the bottom of the main body of the protective frame.
[0014] By adopting the above technical solution, the four sets of lifting lugs on both sides and the bottom swivel wheels form a multi-dimensional mobile system. The lifting lugs support crane lifting and are suitable for long-distance cross-scene transportation; the swivel wheels provide flexible ground mobility, allowing the protective shed to be pushed to the work site by a single person.
[0015] Furthermore, a side door is hinged to one side of the main body of the protective frame, and one side of the side door is locked to the main body of the protective frame by a padlock.
[0016] By adopting the above technical solution, the hinged design of the side door, combined with the padlock limit, forms a lockable safe compartment. During the storage of welding equipment, the side door can effectively block external physical impacts and the effects of severe weather, reducing the risk of equipment theft.
[0017] Furthermore, a limit frame is fixed on the other side of the protective frame body for placing a fire extinguisher, and a sloping canopy is welded and fixed to the top of the protective frame body.
[0018] By adopting the above technical solutions, the dedicated fire extinguisher storage space in the limiting frame ensures the immediate availability of fire-fighting equipment. Its fixed position prevents fire extinguishers from tipping over or being lost during movement, which complies with safety production standards. At the same time, the welded fixing structure of the sloping roof not only strengthens the load-bearing capacity of the overall frame, but also effectively drains rainwater and snow through the sloping diversion design, preventing corrosion problems caused by water accumulation on the top.
[0019] In summary, the present invention has the following main advantages:
[0020] 1. This utility model uses a placement plate, a sliding groove, and a slider. By lifting the placement plate and rotating it to a horizontal position with the central axis of the slider as the axis, it is then pushed along the sliding groove to the upper part of the protective frame body. Finally, it is fixed to the frame body by snap-fitting pieces. This achieves effective storage of long power cords, while reducing the overall size of the protective device and enhancing the mobility and passability of the protective device.
[0021] 2. This utility model uses a snap-fit device that, in conjunction with the protective frame body, creates a fixed position structure for the placement plate during storage. This effectively prevents the plate from accidentally slipping out during transportation or vibration, ensuring that the power cord is always stably stored and avoiding cable scattering or structural damage due to positional displacement. At the same time, this snap-fit mechanism simplifies the operation process through a mechanical self-locking principle. Operators can fix and unlock the placement plate without the need for additional tools, significantly improving work efficiency. It is especially suitable for construction scenarios that require frequent workstation relocation. Attached Figure Description

[0028] The technical solutions of the present invention will be clearly and completely described below with reference to the accompanying drawings. The embodiments described below with reference to the accompanying drawings are exemplary and are only used to explain the present invention, and should not be construed as limiting the present invention.
[0029] Example 1:
[0030] A protective device for a manual arc welding machine, such as Figure 1-5 As shown, the device includes a protective frame body 1, with a placement plate 3 movably mounted on the front side of the protective frame body 1. A slot 5 is formed on the upper front side of the protective frame body 1, and sliding grooves 6 are formed on the upper sides of both sides of the interior of the protective frame body 1. The two sides of the placement plate 3 are slidably connected by sliders 7 and sliding grooves 6, and can be stored inside the upper interior of the protective frame body 1 through the slots 5. The sliding connection between the protective frame body 1 and the movable placement plate 3 realizes the integration of power cord storage function. The placement plate 3 can be completely stored inside the upper interior of the protective frame body 1 along the slots 5 through the cooperation of sliders 7 and sliding grooves 6, which significantly reduces the space occupation problem caused by the traditional exposed power cord, making the overall size of the protective shed more compact. At the same time, this storage mechanism avoids the safety hazards caused by power cord dragging and wear, and extends the service life of the equipment. After storage, the protective shed is no longer restricted by the power cord when moving, which greatly improves the transfer efficiency of the construction site, and is especially suitable for multi-scenario operation needs under complex working conditions.
[0031] See Figure 1 , Figure 2 The surface of the placement plate 3 is fixed with several hooks 4, which are in an "L" shape. The power cord is placed on the surface of the placement plate 3 by winding it around the hooks 4, which can realize the layered or zoned winding and fixing of the power cord. This effectively avoids the problems of cable knotting and scattering caused by traditional random stacking, and improves the standardization of on-site operations. At the same time, the arrangement of the hooks 4 supports the classified management of multi-strand power cords, and the target line can be quickly located when needed, shortening the preparation time. Furthermore, by limiting the swing amplitude of the power cord, the probability of it colliding with surrounding equipment is further reduced, providing a safer and more efficient cable management solution for welding operations.
[0032] Example 2:
[0033] See Figure 1 , Figure 5Two snap-fit pieces 8 are fixed on one side of the placement plate 3 near the protective frame body 1. When the placement plate 3 is in the storage state, the placement plate 3 is snapped into the protective frame body 1 by the snap-fit pieces 8 to limit the position of the placement plate 3, ensuring the absolute stability of the placement plate 3 in the storage state. Even if the protective shed moves on a bumpy road, the snap-fit structure can prevent the placement plate 3 from accidentally sliding out and avoid the power cord from being scattered again. At the same time, this limiting mechanism simplifies the operation process. No additional fixing tools are required when storing it. It is only necessary to push in the snap-fit to lock it, which improves the operation efficiency. Its reliable mechanical connection characteristics also provide structural durability for long-term high-frequency use scenarios and reduce maintenance costs.
[0034] See Figure 1 , Figure 2 , Figure 3 The slider 7 has a circular cross-section, allowing it to slide and rotate inside the groove 6. The placement plate 3 is made of wood, enabling it to both slide and rotate within the groove 6. This allows the placement plate 3 to smoothly transition from a vertical to a horizontal position. This dual-degree-of-freedom motion characteristic allows operators to quickly adjust the posture of the placement plate 3 without disassembly, significantly reducing the complexity of the storage operation. At the same time, the wooden placement plate 3 is lightweight and impact-resistant, reducing the overall weight and effectively buffering the squeezing and collision during power cord storage. The natural damping properties of wood can also suppress cable vibration, further improving the stability of the equipment operation.
[0035] See Figure 1 , Figure 2 , Figure 3 The protective frame body 1 has four sets of lifting lugs 9 installed on both sides, and universal wheels 11 installed at the bottom. The four sets of lifting lugs 9 on both sides and the universal wheels 11 at the bottom constitute a multi-dimensional mobility system. The lifting lugs 9 support crane lifting and are suitable for long-distance cross-scene transportation. The universal wheels 11 provide flexible ground mobility, allowing the protective shed to be pushed to the work site by a single person. At the same time, the lifting mode is suitable for large construction site transfers, while the wheeled movement is suitable for local movement, realizing multi-scene adaptability. The wheel brake system can ensure parking stability and prevent accidental slippage when working on slopes.
[0036] See Figure 1 , Figure 2 , Figure 3 A side door 10 is hinged to one side of the main body 1 of the protective frame. One side of the side door 10 is locked to the main body 1 of the protective frame by a padlock. The hinge of the side door 10, together with the padlock locking, forms a lockable safe compartment. During the storage of welding equipment, the side door 10 can effectively block external physical impacts and the effects of severe weather, reducing the risk of equipment theft. At the same time, it facilitates equipment inspection and maintenance. The padlock adopts a standardized interface, which allows users to quickly replace the lock, improving the flexibility and compatibility of the security system.
[0037] See Figure 1 , Figure 2 , Figure 3 On the other side of the main body 1 of the protective frame, a limiting frame 12 is fixed for placing fire extinguishers. The top of the main body 1 of the protective frame is welded and fixed with a sloping canopy 2. The dedicated fire extinguisher storage position of the limiting frame 12 ensures the immediate availability of fire-fighting equipment. Its fixed position setting avoids the tipping or loss of fire extinguishers during movement, which complies with safety production standards. At the same time, the welded and fixed structure of the sloping canopy 2 not only strengthens the load-bearing capacity of the overall frame, but also effectively drains rainwater and snow through the sloping diversion design, preventing corrosion problems caused by water accumulation on the top. The functional combination of the canopy and the limiting frame 12 enables the protective shed to provide basic protection for welding operations while integrating fire emergency functions, forming a complete safety guarantee system.
[0038] The implementation principle of this embodiment is as follows: The device uses the protective frame body 1 as the basic frame, and the top is welded and fixed with a sloping canopy 2 to provide sun and rain protection. A movable placement plate 3 is set on the front side of the protective frame body 1. When the placement plate 3 is stored, firstly, the placement plate 3 is lifted and rotated around the central axis of the slider 7 until the vertical placement plate 3 is rotated to a horizontal state. Then, through the sliding connection between the slider 7 and the slide groove 6, the placement plate 3 is pushed to the upper part of the interior of the protective frame body 1. The placement plate 3 is locked and limited to the protective frame body 1 by the snap-fit piece 8 to ensure that the position is fixed, thus completing the storage operation of the placement plate 3 and the power cord on the surface. Several L-shaped hooks 4 are fixed on the surface of the placement plate 3 for winding and storing the power cord to avoid mess. Universal wheels 11 are installed at the bottom of the protective frame body 1, and lifting lugs 9 are provided on both sides for easy handling and fixing. A side door 10 is hinged on one side and fastened with a padlock to enhance safety; a limiting frame 12 is fixed on the other side for placing fire extinguishers.
