Abstract
Description
Technical Field
[0001] This utility model belongs to the field of electric welding machine technology, and specifically refers to an electric welding machine housing. Background Technology
[0002] Welding machines generate a lot of heat during operation. Some of this heat is dissipated through the internal cooling system, but some is conducted upwards to the top of the machine casing, causing the handle located there to become hot. Operators are highly susceptible to burns when gripping the handle immediately after the welding machine has stopped working, posing a significant safety hazard.
[0003] To address the aforementioned problems, various improvement solutions have been proposed in the prior art. For example, Chinese utility model patent CN207139088U discloses a welding machine housing that enhances heat dissipation and improves the structural strength of the handle by incorporating a zigzag structure in the middle of the handle, including multiple horizontally arranged heat dissipation sections and connecting sections to form a heat dissipation gap. This solution reduces the handle temperature to some extent, minimizing the risk of burns, while also enhancing the mechanical stability of the handle and preventing the welding machine from falling due to handle breakage.
[0004] However, the handle's convoluted design and multiple heat dissipation sections increase material usage and processing difficulty, raising production costs. Furthermore, its small and densely distributed heat dissipation gaps easily accumulate dust and debris, making cleaning inconvenient and potentially affecting heat dissipation performance in the long run. Therefore, further optimization of the welding machine handle's structural design is needed to ensure heat dissipation performance and structural strength while also considering cost, aesthetics, and user experience. Summary of the Invention
[0005] In view of the shortcomings of the existing technology, the purpose of this utility model is to provide a welding machine housing.
[0006] The objective of this utility model can be achieved through the following technical solution: A welding machine housing includes an upper shell and a lower shell, which are nested and fixedly connected to each other. A left fixing member is fixedly connected to the left side of the lower shell, and a right fixing member is fixedly connected to the right side of the lower shell. The right fixing member includes a first fixing part and a second fixing part. The first fixing part has a first fixing groove, and the right side of the upper shell and the lower shell is embedded in the first fixing groove. The second fixing part has a second fixing groove. A connecting seat is fixedly connected to the upper end of the upper shell, and a third fixing groove is provided on the connecting seat. A handle is directly fixedly mounted on the second fixing groove and the third fixing groove. The left fixing member has a fourth fixing groove, and the left side of the upper shell and the lower shell is embedded in the fourth fixing groove. This solution uses the second fixing groove and the third fixing groove on the connecting seat to suspend and fix the handle, creating a gap channel for air circulation. The heat generated when the welding machine is working is conducted to the housing, and the heat accumulated in the handle mounting area is continuously carried away through natural air convection. This air gap serves as an effective insulation layer and heat dissipation channel, fundamentally preventing direct and rapid heat conduction to the handle. This physical isolation method more efficiently and directly prevents the handle temperature from rising rapidly, significantly reducing the risk of burns to operators and greatly improving safety. A robust frame structure is formed by the left and right fixing components and the connecting seat. The edges of the upper and lower shells are respectively embedded in the first and fourth fixing slots, ensuring the strong connection and overall rigidity of the shell itself. The right fixing component is first fixed to the upper and lower shells, then the handle is inserted into the second and third fixing slots, and finally the connecting seat is fixed to the upper shell. Both ends of the handle are securely locked in the second and third fixing slots. The force generated when gripping the handle and any potential impact force are effectively dispersed and transferred to the entire right fixing component, connecting seat, and the entire housing frame, avoiding stress concentration. This allows the handle to not only withstand the weight of carrying the welding machine but also resist collisions and impacts during daily work, greatly reducing the risk of equipment falling due to handle breakage and improving structural stability and durability. This solution improves heat dissipation and structural strength while reducing complex material processing steps, which helps control production costs and achieves an excellent balance between performance, aesthetics and cost.
[0007] Furthermore, the second fixing part is also provided with a heat insulation groove, which is located inside the first fixing groove and between the second fixing groove.
[0008] Furthermore, at least two heat dissipation columns are protruding on the inner wall of the heat insulation groove, and each heat dissipation column has a heat dissipation hole in the middle, with the opening of the heat dissipation hole located at the outer end of the second fixing part.
[0009] Furthermore, the connecting seat is provided with a heat insulation cavity, which is located between the third fixing groove and the upper shell.
[0010] Furthermore, the bottom of the fourth fixing groove is open on both sides, and the left fixing member is fixedly connected to the lower shell through the fixing member. This facilitates ventilation of the lower shell and easy connection of electrical wires.
[0011] Furthermore, the handle is through the middle, the lower end of the handle is smooth, the upper end of the handle has a damping protrusion, the second fixing groove has a cross-shaped and protruding first positioning strip, the third fixing groove has a cross-shaped and protruding second positioning strip, and the two ends of the handle abut against the first positioning strip and the second positioning strip respectively.
[0012] Furthermore, the bottom of the first fixing groove is open from left to right, the first fixing part is located in the first fixing groove and a display panel is fixedly connected thereto, and a transparent cover is rotatably connected to the first fixing part, the transparent cover covering the display panel.
[0013] Furthermore, the display panel is equipped with a display screen and adjustment buttons. The display screen occupies two-thirds of the display panel and can display large numbers for easy viewing. The adjustment buttons can be rotated 360 degrees for adjustment.
[0014] Compared with existing technologies, the technical advantages of this utility model are as follows: 1. By using an integrally molded right fixing component and connecting seat to fix the handle in the air, a heat-insulating channel for air circulation is formed between the handle and the high-temperature housing. This effectively blocks and dissipates heat through air convection, significantly reducing the working temperature of the handle and fundamentally preventing burns to operators, thus greatly improving safety. 2. The left fixing component, right fixing component, and connecting seat together form a robust frame structure, firmly integrating the handle into this frame. This effectively distributes lifting and impact forces throughout the housing, avoiding stress concentration and greatly improving the load-bearing capacity of the handle and the impact resistance of the housing, thus preventing the risk of equipment falling. 3. While achieving safety and robustness, the structure is simplified, reducing complex processing costs and dust accumulation problems, making the equipment more aesthetically pleasing and easier to maintain. The added display panel and transparent cover further facilitate operator monitoring and parameter adjustment, enhancing the overall functionality and human-machine interface of the equipment.

[0023] according to Figures 1 to 5 As shown, this utility model provides a welding machine housing, including an upper shell 1 and a lower shell 2.

[0024] A left fixing member 3 is fixedly connected to the left side of the lower shell 2, and a right fixing member 4 is fixedly connected to the right side. The right fixing member 4 is an integrally formed component, comprising a first fixing part 41 and a second fixing part 42. The first fixing part 41 has a first fixing groove 411 facing left. The right edges of the upper shell 1 and the lower shell 2 are jointly embedded and fixed in the first fixing groove 411, and then the right fixing member 4 is fixed to the lower shell 2 with screws.

[0030] This embodiment uses the left fixing member 3, the right fixing member 4, and the connecting seat 5 to form a robust load-bearing frame, greatly enhancing the overall rigidity and impact resistance of the casing. Simultaneously, the design of the suspended handle 6, heat insulation groove 43, heat dissipation hole 432, and heat insulation cavity 52 creates an effective air insulation and heat dissipation channel between the handle 6 and the heating casing. Utilizing natural air convection for continuous heat dissipation, it fundamentally prevents the handle 6 from overheating, significantly improving the safety and durability of the equipment.
