[0020] The technical solutions in the embodiments of the utility model will be apparently and completely described in connection with the drawings in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, rather than all the embodiments. Based on the embodiments in the utility model, all other embodiments obtained by those skilled in the art without creative labor fall within the scope of protection of the utility model. EMBODIMENT
[0021] Please refer to Figures 1-4 The utility model provides the following technical scheme: a handheld welding device with a protection structure, including electric welding machine 1 and handheld welding torch 2 connected with the front end of electric welding machine 1, the front end of electric welding machine 1 is installed with control panel 7, the side wall of electric welding machine 1 is fixedly connected with winding disc 3, the side wall of electric welding machine 1 is fixedly connected with storage box 4, the top end of storage box 4 is rotatably connected with lid 5 through hinge, and the front end of storage box 4 is installed with lock catch 6.
[0022] In the preferred embodiment, the cross section of the winding disc 3 is in the shape of "T".
[0023] In the preferred embodiment, the lid 5 is detachably connected between the lock catch 6 and the storage box 4.
[0024] In the preferred embodiment, the front end of the storage box 4 is provided with a notch for the power cord of the handheld welding torch 2.
[0025] In the embodiment, first, the handheld welding device is a mature technology, and when in use, the worker needs to start the electric welding machine 1 and hold the handheld welding torch 2 close to the material for welding operation. Since the working principle of the device is not directly related to the technical features in the text, it will not be described in detail here.
[0026] In addition, after using the handheld welding device, the worker can neatly wind the long power cord on the winding disc 3. Then, in order to store the handheld welding torch 2, the operator needs to open the lock catch 6, rotate the lid 5 to expose the inside of the storage box 4, and then safely place the handheld welding torch 2 in the storage box 4. This not only effectively avoids the scattering of the power cord, ensures the neatness and order of the working environment, but also effectively protects the power cord from external damage, thereby ensuring that the handheld welding device can be used continuously and normally without being affected.
[0027] It is worth noting that: since the handheld welding torch 2 will generate high temperature after use, it needs to be cooled down or placed in a storage box 4 made of high-temperature-resistant material. Then the power cord may not be affected by high temperature. EMBODIMENT
[0028] Please refer toFigures 1-4 The front end of the electric welding machine 1 is connected with fixed blocks 9 on both sides of the control panel 7, and a protective plate 8 is arranged between the two fixed blocks 9.
[0029] In the preferred embodiment, the side walls of the two fixed blocks 9 are provided with grooves 10, and guide rods 12 are arranged in the grooves 10.
[0030] In the preferred embodiment, the size of the limiting block 11 is matched with the size of the groove 10, and the limiting block 11 is elastically connected with the guide rod 12 through the spring 13.
[0031] In the preferred embodiment, when the electric welding machine 1 is started or the parameters need to be adjusted through the control panel 7, the palm of the hand is covered on the protective plate 8 and pulled down. This action makes the protective plate 8 descend, drives the limiting block 11 on the protective plate 8 to smoothly descend along the surface of the guide rod 12, and the descent of the limiting block 11 will extrude the spring 13 to make it contract. With the continuous descent of the protective plate 8, the control panel 7 is exposed, which is convenient for operation. The original intention of the design of the protective plate 8 is to shield and protect the control panel 7, effectively prevent the collision that may occur when the artificial hand-held welding gun 2 moves, avoid the damage of the control panel 7, and further enhance the durability and operation safety of the equipment.
[0032] It is worth noting that the protective plate 8 is made of PVC material, which allows the artificial to observe the control panel 7 through the transparent protective plate 8, thereby avoiding the problem that the data change of the control panel 7 is difficult to observe due to the shielding of the protective plate 8.
[0033] Finally, it should be pointed out that the above only describes the preferred embodiments of the present application and is not used to limit the present application. Although the present application has been described in detail with reference to the foregoing embodiments, those skilled in the art can still modify the technical solutions recorded in the foregoing embodiments or equivalently replace some technical features. Any modification, equivalent replacement, improvement, etc. made within the spirit and principles of the present application shall be included in the protection scope of the present application.
