Abstract
Description
Technical Field
[0001] The utility model relates to the field of welding, in particular to a protective device for sheet metal welding. Background Art
[0002] During the sheet metal welding process, in order to ensure the safety of welders and prevent accidents, welders need to be protected with the help of protective devices. Protective devices include protective masks and protective clothing, which are mainly used to protect welders from sparks and spatters, and to prevent welders' clothing from catching fire or fires caused by hot spatters and sparks.
[0003] Before using the current protective mask, the filter is usually fixed to the mask with screws. Therefore, when removing and replacing the filter, tools such as screwdrivers are needed. However, there may be no tools during welding operations, which makes the efficiency of installing and removing the filter low. In addition, when welders use the protective mask, their hands will be tired due to holding the mask for a long time, thereby reducing work efficiency. Therefore, a protective device for sheet metal welding is proposed to address the above problems. Utility Model Content
[0004] In order to make up for the shortcomings of the prior art and avoid the problem of low efficiency in installing and removing filters, the utility model provides a protective device for sheet metal welding.
[0005] The utility model solves the technical problem by adopting the following technical solution: a protective device for sheet metal welding, comprising a protective mask, a gripping rod fixedly mounted on the bottom end of the protective mask, a convenient assembly and disassembly component arranged inside the protective mask, and a labor-saving component arranged on the surface of the protective mask;
[0006] The convenient assembly and disassembly component includes a placement groove opened inside the protective mask, a filter is clamped inside the placement groove, and clamping blocks are fixedly installed at the upper and lower ends of the filter. Vertical grooves are opened inside the upper and lower ends of the placement groove, and a pressure spring is fixedly installed on the inner wall of the vertical groove away from the placement groove, and an abutment block is fixedly installed on the other end of the pressure spring.
[0007] Preferably, both upper and lower ends of the placement groove are provided with a card slot, the card slot is located on the rear side of the pressure spring, and the card block is carded inside the card slot. After the card block is carded inside the card slot, the card block is initially confined inside the placement groove.
[0008] Preferably, one end of the abutment block away from the pressure spring abuts against the end face of the filter close to the card block, and the abutment block and the card block are in adaptive contact, and the abutment block confines the card block inside the card slot, further limiting the position of the filter.
[0009] Preferably, the labor-saving component includes two rotating rods rotatably connected to the left and right sides of the bottom end of the protective mask, the end of the rotating rod away from the protective mask is rotatably connected to a connecting rod, the end of the connecting rod away from the rotating rod is provided with a groove, the inside of the groove is rotatably connected to a pressure rod, a tension spring is fixedly installed on the surface of the pressure rod, hollow fixed blocks are fixedly installed on the left and right sides of the rear end of the top of the protective mask, the inside of the hollow fixed block is rotatably connected to a winding rod, and the surface of the winding rod is fixedly connected to an elastic band.
[0010] Preferably, the rotating rod rotates in a horizontal direction at the bottom end of the protective mask, the connecting rod and the pressure rod rotate in a vertical direction, and the end of the tension spring away from the pressure rod is fixedly installed on the inner wall of the groove. The operator can rotate the rotating rod, the connecting rod and the pressure rod, and then adjust the pressure rod to press on the welder's shoulder. At this time, the pressure rod supports the protective mask and reduces the force on the welder's arm.
[0011] Preferably, the two ends of the elastic band are respectively connected to two winding rods, and the welder can wrap the elastic band around his head to further support the protective mask, thereby further reducing the force on the welder's hands so that the welder's hands will not be sore during operation.
[0012] The utility model is beneficial in that:
[0013] The utility model firmly clamps the card block in the card slot through the abutment block, thereby achieving the effect of installing the filter. When removing the filter, the abutment block is pushed away from the filter. At this time, the abutment block no longer limits the card block. At this time, the operator can directly remove the card block without the help of tools, thereby achieving the purpose of quickly removing the filter. Therefore, the installation and removal of the filter do not require the help of tools and are simple and convenient, which also improves the efficiency of installing and removing the filter.
[0014] By adjusting the position of the pressure rod so that it is pressed on the welder's shoulder, the elastic band can be hooped around the head, thereby reducing the force on the welder's arm when supporting the protective mask, reducing the fatigue of the welder's arm, and making the welder's welding work more comfortable.
