Detailed description of the invention

Below in conjunction with drawings and Examples, detailed description of the invention of the present utility model is described in further detail.Following examples for illustration of this utility model, but are not used for limiting scope of the present utility model.

As Figure 1-Figure 5, a kind of welding mask, comprises weld cap 1, screening glass 2, filter 3, pressure card 4 and clamping block 5, described weld cap 1 includes through hole 101, the edge of described through hole 101 is provided with one towards weld cap 1 internal protrusion and around the liner plate seat 102 of through hole 101, described screening glass 2, filter 3 and pressure card 4 are arranged in liner plate seat 102 successively, the top of card 4 is wherein pressed to coordinate clamping with the top of liner plate seat 102 and rotatable, the bottom of described liner plate seat 102 arranges one with first card adapter plate 104 of lateral surface with the first draw-in groove 103, the arranged outside of described pressure card 4 has an end face with the second card adapter plate 402 of the second draw-in groove 401, described first card adapter plate 104 connecting lining plate seat 102 and weld cap 1 respectively, the structure between liner plate seat 102 and weld cap 1 can also be strengthened like this.

As shown in Figure 6, described clamping block 5 is positioned at the bottom of pressure card 4 and comprises two parallel horizontal stripes 501 and several are horizontally arranged in the vertical bar 502 of two horizontal stripes 501, the two ends of described vertical bar 502 connect 2 horizontal stripes 501 respectively thus form spacer holes 503 with horizontal stripe 501, the horizontal stripe 501 on top is also provided with button 504, described button 504 rotates for axle center up and down with the horizontal stripe 501 of bottom, the shape of wherein said first draw-in groove 103 is major arc, and the shape of described second draw-in groove 401 is minor arc.

As shown in figs 1 to 6, during assembling, first the horizontal stripe 501 of clamping block 5 middle and lower part is snapped fit onto in the first draw-in groove 103, the shape of wherein said first draw-in groove 103 is major arc, the horizontal stripe 501 of described bottom can rotate in the first draw-in groove 103, described screening glass 2 simultaneously, filter 3 and pressure card 4 are arranged in liner plate seat 102 successively, and the top of pressure card 4 and liner plate seat 102 rotary clamping, then breaking button on drives clamping block 5 to rotate up, spacer holes 503 is made to be socketed in the first card adapter plate 104 and the second card adapter plate 402, and the horizontal stripe 501 on top snaps fit onto in the second draw-in groove 401, thus make screening glass 2 and filter 3 be fixedly mounted on weld cap 1 by pressure card 4, therefore assemble very convenient.

Pluck when unloading, move button 504 with hands and drive clamping block 5 to be rotated down, after the horizontal stripe 501 on top departs from the second draw-in groove 401, thus horizontal stripe 501 is separated with the second draw-in groove 401, thus screening glass 2 and filter 3 can be removed, therefore dismantle very convenient.

Described first card adapter plate 104 and the second card adapter plate 402 are provided with fillet, so clamping block 5 can be prevented to be stuck when rotated.

In certain above-described embodiment, the top of described pressure card 4 and the top of liner plate seat 102 also can not be designed to coordinate clamping and rotatable structure, the structure that other connect can be designed to, can certainly with the interface arrangment arranging clamping block 5 in above-described embodiment, the interface arrangment of clamping block 5 does not design the bottom at pressure card 4 or liner plate seat 102 yet in other words, all be arranged on the left and right sides of pressure card 4 or liner plate seat 102, thus form symmetrical clamping, dismounting mode also still facilitates compared to existing technology, and dismounting speed is fast.

The above is only preferred implementation of the present utility model; should be understood that; for those skilled in the art; under the prerequisite not departing from this utility model know-why; can also make some improvements and modifications, these improvements and modifications also should be considered as protection domain of the present utility model.
