Description

Technical Field

[0001] This utility model belongs to the field of electric welding machine technology, and specifically refers to an electric welding machine with a protective structure. Background Technology

[0002] Electric welding machines, as key equipment that uses an electric arc heat source to join metal materials, are widely used in many industrial fields such as machinery manufacturing, construction, and ship repair. Their basic principle is to melt the welding rod or wire using a high-temperature arc generated when the positive and negative electrodes are short-circuited, thereby achieving the joining of workpieces. Traditional electric welding machines typically include a transformer, rectifier circuit, control unit, and output interface. While continuously improving welding performance and efficiency, safety issues have gradually attracted attention.

[0003] In existing technologies, for example, CN213614703U discloses a safety-type welding machine that provides overcurrent protection through the installation of fuse-equipped circuit breakers and air switches, enhances heat dissipation performance using multiple heat sinks, and is equipped with casters to improve mobility. Nevertheless, such equipment still has significant shortcomings in terms of the safety of the operating interface. Control components such as air switches and adjustment knobs are usually directly exposed outside the protective structure of the welding machine, lacking effective protection. They are easily touched accidentally during handling, stacking, or collaborative operations, leading to parameter changes or erroneous equipment startup. This not only affects welding quality but may also cause serious accidents such as electric shock, short circuits, or arc burns. Summary of the Invention

[0004] The purpose of this utility model is to overcome the shortcomings of the prior art and provide a welding machine with a protective structure. The protective structure effectively protects the operating interface, fundamentally avoiding parameter changes and equipment malfunctions caused by accidental contact, and significantly improving the safety of the equipment.

[0005] The objective of this utility model can be achieved through the following technical solution: A welding machine with a protective structure includes a left shell, a right shell, and a front shell; the left shell and the right shell are fixedly connected, and the front shell is snapped and fixed between the left shell and the right shell; the upper part of the front shell is recessed and formed with a mounting groove, and an operation panel is fixedly installed in the mounting groove. The operation panel includes at least one control element, and the highest point of the control element is not higher than the groove opening plane of the mounting groove; a flip-top protective cover is provided on the front shell in the area corresponding to the operation panel; one side of the flip-top protective cover is hinged to the front shell through a pivot, so that the flip-top protective cover can rotate relative to the front shell between a closed position and an open position. The closed position is the position where the flip-top protective cover covers the operation panel, and the open position is the position where the flip-top protective cover exposes the operation panel; the flip-top protective cover is provided with a locking mechanism for locking it to the front shell when the flip-top protective cover is in the closed position. The flip-top protective cover of this design completely covers and locks the control components on the operation panel when closed. Parameter adjustments can only be made after a deliberate opening operation, greatly reducing the risk of misoperation and avoiding potential safety accidents such as electric shock and short circuits. Multiple mounting posts are provided on the right or left housing for mounting the control mainboard.

[0006] Furthermore, the flip-top protective cover is made of transparent or semi-transparent engineering plastic, allowing the status or parameter display of the operation panel to be observed when the cover is closed. The use of transparent or semi-transparent materials for the flip-top protective cover enables users to observe the parameter status of the digital display screen or the working status of the indicator lights without opening the flip-top, thus balancing protection and ease of operation.

[0007] Furthermore, the control element includes a horizontally arranged push-button switch and an adjustment knob; the operation panel is also equipped with a digital display screen and four indicator lights; the indicator lights are located between the push-button switch and the adjustment knob; the digital display screen is located above the push-button switch.

[0008] Furthermore, the control element is a push-button knob, which is arranged laterally adjacent to the integrated display screen; the lateral width of the integrated display screen occupies at least two-thirds of the lateral width of the operation panel. The laterally adjacent arrangement of the push-button knob and the integrated display screen, along with the large screen area, conforms to ergonomics, facilitating operation and viewing. The push-button knob is pressed to select the relevant function, and rotated 360 degrees to adjust the parameter value.

[0009] Furthermore, the top of the left housing is integrally formed with a left handle, and the bottom of the left housing is integrally formed with a left support protrusion; the top of the right housing is integrally formed with a right handle, and the bottom of the right housing is integrally formed with a right support protrusion; the left handle and the right handle are fixedly connected by fastener one, and the left support protrusion and the right support protrusion are fixedly connected by fastener two. Both the left and right handles have sections of heat insulation holes inside.

[0010] Furthermore, a rear shell is fixedly connected between the left and right shells, a main switch is installed on the upper part of the rear shell, and a heat dissipation hole is formed on the lower part of the rear shell, with the highest point of the heat dissipation hole being higher than the plane where the highest point of the main switch is located.

[0011] Furthermore, the locking mechanism is a magnetic snap fastener, which includes a first magnetic component and a second magnetic component; the first magnetic component is fixedly disposed on the flip cover protective cover; the second magnetic component is fixedly disposed on the front shell and corresponds to the position of the first magnetic component.

[0012] Furthermore, the locking mechanism includes an interference fit protrusion and a groove; the protrusion is integrally formed on the end of the flip cover away from the pivot; the groove is formed on the front shell and its position corresponds to the protrusion.

[0013] Furthermore, the flip-top protective cover is formed with a pair of lugs, and a rotating shaft is provided on the outer side of the lugs; the front shell is provided with a shaft hole that mates with the rotating shaft, and the rotating shaft is rotatably supported in the shaft hole; a locking protrusion is also provided on the outer side of the lugs; the left shell and / or the right shell is provided with a locking groove that mates with the locking protrusion.

[0014] Compared with existing technologies, the technical advantages of this utility model are as follows: 1.

[0022] The following are specific embodiments of the present invention, which are described in conjunction with the accompanying drawings. However, the present invention is not limited to these embodiments.

[0023] It should be noted that the descriptions of "up", "down", "left", "right", "top", "bottom", etc. in this utility model are defined based on the orientation or positional relationship shown in the accompanying drawings. They are only for the convenience of describing this utility model and simplifying the description, and are not intended to indicate or imply that the device must be constructed and operated in a specific orientation. Therefore, they should not be construed as limitations on this utility model.

[0024] Example 1: As Figures 1 to 5 As shown, a welding machine with a protective structure mainly includes a left housing 1, a right housing 2, a front housing 3, and a rear housing 4. The left housing 1 and the right housing 2 are fixedly connected by screws and other fasteners to form the main frame of the welding machine. The front housing 3 and the rear housing 4 are both fixed between the left housing 1 and the right housing 2 by snap-fit, together forming the complete outer shell of the welding machine.

[0025] A recessed mounting groove 31 is formed in the upper part of the front housing 3. An operation panel 5 is fixedly mounted in this groove 31 using screws. The operation panel 5 includes control elements; in this embodiment, the control elements include a push-button switch 51 and an adjustment knob 52, arranged horizontally. The operation panel 5 also features a digital display screen 53 and four indicator lights 54 (such as LED indicator lights). The four indicator lights 54 are located between the push-button switch 51 and the adjustment knob 52, while the digital display screen 53 is positioned above the push-button switch 51. Importantly, the highest point of all control elements does not exceed the opening plane of the mounting groove 31, allowing the control panel to be embedded within the front housing 3, providing the first line of physical protection.

[0026] On the front cover 3, corresponding to the area of ​​the operation panel 5, a flip-top protective cover 6 is hinged via a pivot 62. Specifically, a pair of lugs 61 are formed on one side of the flip-top protective cover 6, and the pivot 62 protrudes outward from the outer side of the lugs 61. A shaft hole 32 is provided on the front cover 3 at a corresponding position to cooperate with the pivot 62. The pivot 62 is rotatably supported within the shaft hole 32, allowing the flip-top protective cover 6 to rotate relative to the front cover 3 between a closed position and an open position. When the flip-top protective cover 6 is in the closed position, it completely covers the operation panel 5; when in the open position, the operation panel 5 is fully exposed and operable. To ensure the stability of the flip-top protective cover 6 in the closed state, a locking mechanism is provided. In one implementation of this embodiment, the locking mechanism is a magnetic clasp, including a first magnetic element and a second magnetic element. A first magnetic component (such as a magnet) is fixedly embedded in the inner side of the end of the flip-top protective cover 6 away from the pivot 62; a second magnetic component (such as an iron adsorption block or another magnet) is fixedly embedded in the front shell 3 at a position corresponding to the first magnetic component. When the flip-top protective cover 6 is closed, the two are locked by magnetic attraction. In another embodiment, the locking mechanism may also adopt a mechanical interference fit structure, including a protrusion 64 integrally formed on the end of the flip-top protective cover 6 away from the pivot 62, and a groove 33 formed on the front shell 3 at a corresponding position. Tight engagement and locking are achieved through the interference fit between the protrusion 64 and the groove 33. To further ensure the stability of the flip-top protective cover 6 during rotation and installation, a locking protrusion 63 is also provided on the outer side of the lug 61. A locking groove 11 corresponding to the locking protrusion 63 is provided on the left shell 1 and / or the right shell 2. When the flip-top protective cover 6 is installed in place, the locking protrusion 63 engages with the locking groove 11, providing axial restraint and preventing the flip-top protective cover 6 from loosening or falling off during rotation. The flip-top protective cover 6 is preferably made of transparent or semi-transparent engineering plastic (such as polycarbonate PC). This allows users to observe the parameter information of the digital display screen 53 or the working status of the indicator light 54 through the protective cover without opening the flip-top, greatly balancing safety and ease of operation.

[0027] The top of the left housing 1 has a single-piece left handle 12, and the bottom has a single-piece left support protrusion 13. Correspondingly, the top of the right housing 2 has a single-piece right handle 21, and the bottom has a single-piece right support protrusion 22. The left handle 12 and the right handle 21 are fixedly connected by fastener one, and the left support protrusion 13 and the right support protrusion 22 are fixedly connected by fastener two. This design greatly enhances the overall structure and stability of the device. Both the left handle 12 and the right handle 21 have sections of heat insulation holes 14 inside, which effectively blocks heat transfer and improves user comfort and safety when carrying the device.

[0028] The upper part of the rear housing 4 is equipped with a main switch 41, while the lower part has a large number of heat dissipation holes 42. The highest point of the heat dissipation holes 42 is higher than the plane where the highest point of the main switch 41 is located. Multiple mounting posts 23 are provided on the inner wall of the right housing 2 or the left housing 1. These mounting posts 23 are used to fix the control board of the welding machine with screws, providing a stable and reliable mounting base for the internal core circuit.

[0029] Example 2: Figure 6 As shown, unlike the previous embodiment, the control element is a push-button knob 55, which is arranged horizontally adjacent to the integrated display screen 56. The horizontal width of the integrated display screen 56 occupies at least two-thirds of the horizontal width of the operation panel 5. The horizontally adjacent arrangement of the push-button knob 55 and the integrated display screen 56, along with the large screen area, conforms to ergonomics and facilitates operation and viewing. The push-button knob 55 is pressed to select the relevant function, and rotated 360 degrees to adjust the parameter value.

[0030] The above embodiments are merely preferred embodiments of the present utility model and are not intended to limit the scope of protection of the present utility model. Therefore, all equivalent changes made to the structure, shape, and principle of the present utility model should be covered within the scope of protection defined by the claims of the present utility model.
