[0037] The following is combined with Figure 1-7 This application is described in further detail.

[0038] The embodiment of the present application discloses a mask flip structure.

[0039] Reference Figure 1 and Figure 2 , including a plastic panel 1, a transparent cover 2 and a damping rotation structure 3; the damping rotation structure 3 can be detachably arranged on the plastic panel 1, and the damping rotation structure 3 is installed on both sides of the transparent cover 2; by rotating the damping rotation structure 3, the transparent cover 2 and the plastic panel 1 form a hovering at any angle, and the coverage area of ​​the transparent cover 2 is larger than the display area on the plastic panel 1. When the transparent cover 2 is flipped over and covered on the plastic panel 1 of the welding machine, it can effectively protect the covered area to prevent the devices on the plastic panel 1 from being directly hit by other objects, thereby increasing the service life of the product.

[0040] See also Figure 2 As shown, the damping rotation structure 3 consists of a shaft sleeve 31, a damping shaft 32, and a fastening screw 33. The damping shaft 32 is made of standard material and has its own damping effect, so that the transparent cover 2 can hover at any angle when it rotates. In practice, the fastening screw 33 uses a cross screw for easy installation and screwing; the shaft sleeve 31 is L-shaped, one end of the damping shaft 32 is inserted into the shaft sleeve 31, and the other end of the damping shaft 32 is inserted into the transparent cover 2. The fastening screw 33 passes through the shaft sleeve 31 and is threadedly engaged with the plastic panel 1. First, a damping shaft 32 is installed from one side into the preset installation groove of the transparent cover 2, and then the damping shaft 32 and the preset cylinder of the transparent cover 2 are inserted into the inner hole of the shaft sleeve 31. On the other side, the preset cylinder of the transparent cover 2 is inserted into the inner hole of the shaft sleeve 31. The shaft sleeve 31 and the plastic panel 1 are fastened with fastening screws 33 on both sides.

[0041] See also Figure 2 and Figure 6As shown, both sides of the transparent cover 2 are integrally formed with a rotating shaft 4, and a first slotted hole 5 is provided in the rotating shaft 4. The first slotted hole 5 is provided in an "I" shape, and the first slotted hole 5 is plugged into the damping rotating shaft 32. The shape and specifications of the first slotted hole 5 are the same as those of the end of the damping rotating shaft 32, and the transparent cover 2 and the end of the rotating shaft 4 are clamped by plugging.

[0042] See also Figure 2 and Figure 7 As shown, a fixing hole 6 for the fastening screw 33 to pass through is provided on the rotating shaft sleeve 31, and the aperture of the fixing hole 6 is equal to the diameter of the fastening screw 33. A second slotted hole 7 for installing the damping rotating shaft 32 is also provided in the rotating shaft sleeve 31. The fastening screw 33 passes through the fixing hole 6 on the rotating shaft sleeve 31 and is locked with the plastic panel 1. The second slotted hole 7 on the other side of the rotating shaft sleeve 31 is used to guide and limit the installation of the damping rotating shaft 32.

[0043] See also Figure 3 and Figure 4 As shown, a positioning rib 8 is installed on the rotating shaft sleeve 31, and the positioning rib 8 is fixed between the second slot hole 7 and the fixing hole 6 of the rotating shaft sleeve 31. A positioning hole 9 that matches the shape and specification of the positioning rib 8 is opened on the plastic panel 1. The positioning rib 8 and the positioning hole 9 are snap-fitted together. The positioning hole 9 and the positioning rib 8 on the rotating shaft sleeve 31 cooperate with each other, so that the rotating shaft sleeve 31 is fixed at the upper limit on the plastic panel 1 to prevent the rotating shaft sleeve 31 from rotating radially.

[0044] See also Figure 3 As shown, the plastic panel 1 is provided with a mounting hole 10 having the same outer diameter as the shaft sleeve 31. The cylindrical portion of the shaft sleeve 31 matches the mounting hole 10 on the plastic panel 1, facilitating the installation and insertion of the shaft sleeve 31. The plastic panel 1 is also provided with guide ribs 11, which abut against the end surface of the shaft sleeve 31. The guide ribs 11 are located on both sides of the shaft sleeve 31, and the directions of the guide ribs 11 and the positioning ribs 8 on both sides are perpendicular to each other. The guide ribs 11 can quickly install the positioning ribs 8 on the shaft sleeve 31 into the positioning holes 9 on the plastic surface, providing a convenient guide during installation.

[0045] See also Figure 2 and Figure 3 As shown, the plastic panel 1 is integrally formed with a screw column 12, and the screw column 12 and the fastening screw 33 are threadedly matched. The screw column 12 and the fastening screw 33 are assembled in a threaded manner, which is convenient for guiding the installation of the fastening screw 33; the plastic panel 1 is a plastic product, and is pre-set with a screw column. The rotating shaft sleeve 31 is fixed by the fastening screw 33. The screw column 12 and the fastening screw 33 are tightly matched and fixed. When the plastic panel 1 and the rotating shaft sleeve 31 are installed, the deviation of the fastening screw 33 is reduced, and the tightness of the fastening of the plastic panel 1 and the rotating shaft sleeve 31 is improved.

[0046] See also Figure 5As shown, the damping shaft 32 has flat ends and a cylindrical middle, with its flat end faces snapping into the first slot 5 and / or second slot 7. The damping shaft 32 is cross-shaped overall, with both ends having flat ends, allowing for a tight fit within the first slot 5 and second slot 7, respectively. The transparent cover 2 is made of plastic and has a pre-set slot that matches the shape of the damping shaft 32. The slot is non-circular, preventing radial rotation between the mating ends of the transparent cover 2 and the damping shaft 32. The pre-set cylindrical hole in the shaft sleeve 31 mates with the pre-set cylindrical axis of the transparent cover 2, enabling the transparent cover 2 to rotate at any angle.

[0047] The implementation principle of a mask flip structure in an embodiment of the present application is: first, the damping shaft 32 is installed into the preset installation groove on one side of the transparent cover 2, and then the damping shaft 32 and the preset cylinder of the transparent cover 2 are inserted into the inner hole of the shaft sleeve 31, and the preset cylinder of the transparent cover 2 is inserted into the inner hole of the shaft sleeve 31 on the other side, and the shaft sleeve 31 and the plastic panel 1 are fastened with fastening screws 33 on both sides, thereby completing the installation and tight fit of the transparent cover 2 on the plastic panel 1.

[0048] Since a mask, i.e. a transparent cover 2, is installed on the plastic panel 1, the transparent mask avoids blocking the data on the display part, making it convenient for the user to read the display data from the plastic panel 1 on the welding machine; the damping rotation structure 3 is arranged between the transparent cover 2 and the plastic panel 1. When the user flips the transparent cover 2, the damping structure in the damping rotation mechanism itself has a damping effect, which can achieve hovering when the transparent cover 2 is rotated to any angle, thereby improving the convenience of operation for the user; the coverage area of ​​the transparent mask is larger than the display and device position area of ​​the plastic panel 1, and has a good protective effect on the devices and display parts on the plastic panel 1, avoiding the devices and display parts from being directly hit and damaged by other objects, which helps to increase the service life of the product.
