[0029] Referring to Figures 1-3 An embodiment of the present application provides a pinch 10, which comprises a pressing handle 100, a connecting arm 200 and a supporting arm 300. One end of the pressing handle 100 has a buckle part 110, which is used to buckle into a buckle groove 21 of a first connecting piece 20, and the other end of the pressing handle 100 has a pressing part 120; one end of the connecting arm 200 is connected between the buckle part 110 and the pressing part 120, and the other end is used to be connected to a second connecting piece 30, and the connecting arm 200 can be elastically deformed; one end of the supporting arm 300 is used to be connected to one of the pressing handle 100 or the second connecting piece 30, and the other end is used to abut against the other one of the pressing handle 100 or the second connecting piece 30, and the supporting arm 300 is located on the side of the connecting arm 200 away from the buckle part 110.

[0030] In the present embodiment, the connecting arm 200 is connected between the buckle part 110 and the pressing part 120, and when the pressing part 120 is pressed, the connecting arm 200 is bent and deformed, which can make the buckle part 110 lift up, so as to buckle the buckle part 110 into the buckle groove 21 of the first connecting piece 20, and then connect the first connecting piece 20 and the second connecting piece 30. At the same time, when the pressing part 120 is pressed to make the pressing handle 100 rotate by a certain angle, the supporting arm 300 can support the pressing part 120, prevent the connecting arm 200 from being broken between the pressing handle 100 when the rotating angle of the pressing handle 100 is too large, and then reduce the damage to the pinch 10 and prolong the service life.

[0031] Wherein the pinch 10 is used for a breathing mask, the first connecting piece 20 can be a mask body, and the second connecting piece 30 can be a connecting seat of a ventilation pipe; or the second connecting piece 30 can be a mask body, and the first connecting piece 20 can be a connecting seat of a ventilation pipe. Of course, the pinch 10 can also be used in other technical fields, for example, the first connecting piece 20 can be a fixing seat, and the second connecting piece 30 can be a support, and the pinch 10 is used to connect the support and the fixing seat.

[0032] It should be noted that,

[0033] In combination Figure 2 In some embodiments, one end of the support arm 300 is provided with a slope 310, and the support arm 300 abuts against the other one of the pressing handle 100 or the second connecting piece 30 through the slope 310.

[0034] The slope 310 is used to increase the contact area of the support arm 300 and the pressing handle 100 or the second connecting piece 30, thereby reducing the extrusion force on the pressing handle 100 or the second connecting piece 30. Specifically, taking the case that one end of the support arm 300 is connected to the second connecting piece 30 as an example, the support arm 300 abuts against the pressing handle 100 through the slope 310, so as to increase the contact area of the support arm 300 and the pressing handle 100, reduce the extrusion force on the pressing handle 100, and prevent the pressing handle 100 from being broken and damaged.

[0035] In some embodiments, one end of the support arm 300 is used to be connected to the second connecting piece 30, and the pressing handle 100 is provided with a reinforcing rib 130 on one side surface in the pressing direction OY, and the other end of the support arm 300 is used to abut against the reinforcing rib 130.

[0036] In this embodiment, on the one hand, the reinforcing rib 130 is used to improve the pressing strength of the pressing handle 100, and on the other hand, the other end of the support arm 300 is used to abut against the reinforcing rib 130, thereby further preventing the risk of the pressing handle 100 being damaged and broken due to the extrusion force of the support arm 300 on the pressing handle 100 when the pressing force is too large.

[0037] Further, the reinforcing rib 130 has an abutting surface 131, which is inclined towards the side away from the pressing handle 100 along the direction from the clamping portion 110 to the pressing portion 120, and the inclination angle of the abutting surface 131 matches the inclination angle of the slope 310.

[0038] In the embodiment, the thickness of the reinforcing rib 130 gradually increases along the direction from the buckling part 110 to the pressing part 120, so that the abutting surface 131 (i.e. the surface of the reinforcing rib 130 close to the second connecting piece 30) gradually inclines away from the side of the pressing handle 100, and there is also an inclined surface 310 on the supporting arm 300 that matches the inclination angle of the abutting surface 131. When the supporting arm 300 abuts against the reinforcing rib 130 through the inclined surface 310, the supporting arm 300 is in close contact with the abutting surface 131 through the inclined surface 310, and the inclined surface 310 is completely in close contact with the abutting surface 131, which can further reduce the pressure of the pressing handle 100 and improve the service life of the pressing handle 100.

[0039] In some embodiments, the buckling part 110 is located on one side of the pressing handle 100 along the pressing direction OY, and the buckling part 110 is a protruding structure extending along the pressing direction OY.

[0040] In the embodiment, the buckling part 110 is arranged at one end of the pressing handle 100, and the buckling part 110 is located on the side of the pressing handle 100 close to the second connecting piece 30 and extends from the pressing handle 100 towards the second connecting piece 30 to form a protruding structure. Correspondingly, the first connecting structure is provided with a buckling groove 21 recessed along the pressing direction OY, and the protruding structure is used to extend into the buckling groove 21 to connect the first connecting piece 20 and the second connecting piece 30. In order to facilitate the buckling part 110 to be quickly buckled into the buckling groove 21, the thickness of the buckling part 110 can gradually decrease along the pressing direction OY.

[0041] In some other embodiments, the buckling part 110 is a long strip-shaped structure, and the buckling part 110 extends along the length direction of the pressing handle 100. Correspondingly, the first connecting structure is provided with a buckling groove 21 extending along the length direction of the pressing handle 100, and when the pressing handle 100 is pressed, the buckling part 110 is buckled into the buckling groove 21 to connect the first connecting piece 20 and the second connecting piece 30.

[0042] In some embodiments, the side of the pressing handle 100 away from the connecting arm 200 is an arc-shaped surface.

[0043] In one of the embodiments, the pressing handle 100 is entirely in an arc-shaped structure, i.e. the side of the pressing handle 100 away from the connecting arm 200 is an arc-shaped surface. The arc-shaped surface is used to closely fit the curvature of the fingers to improve the pressing comfort of the user.

[0044] In some other embodiments, the surface of the side of the pressing handle 100 for arranging the connecting arm 200 is not limited, and only the side of the pressing handle 100 away from the connecting arm 200 is an arc-shaped surface, which can also improve the pressing comfort of the user.

[0045] Further, the arc-shaped surface is provided with an anti-slip structure.

[0046] The anti-skid structure can be a strip-shaped pattern, a diamond-shaped pattern, or a convex-concave surface arranged at intervals to increase the surface roughness of the pressing handle 100 to prevent the fingers from slipping when the user presses the pressing handle 100.

[0047] In some embodiments, the thickness of the supporting arm 300 gradually increases along the pressing direction OY, so that the thickness of the supporting arm 300 at one end of the second connecting piece 30 is large to ensure the connection strength of the supporting arm 300 and the second connecting piece 30. The length of the supporting arm 300 ranges from 1 mm to 20 mm.

[0048] In combination Figure 2 In some embodiments, the connecting arm 200 is inclined to the side of the pressing portion 120 along the pressing direction. That is, the connecting arm 200 is inclined to the pressing portion 120 along a direction away from the pressing direction, so that when the pressing portion 120 is pressed, the connecting arm 200 is inclined to the side of the pressing portion 120, and the buckling portion 110 can be buckled to the buckle groove 21 of the first connecting piece 20. In addition, the connecting arm 200 is inclined to the pressing portion 120 along a direction away from the pressing direction, and when the buckling portion 110 is buckled into the buckle groove 21, the connecting arm 200 has an axial pulling force on the buckling portion 110 and towards the end of the pressing portion 120, to prevent the buckling portion 110 from being pulled out of the buckle groove 21.

[0049] In some embodiments, the shape of the connecting arm 200 includes but is not limited to an “I” shape, an “L” shape, a “Z” shape, and the like, and the length of the connecting arm 200 ranges from 1 mm to 100 mm. The width of the handle ranges from 5 mm to 50 mm.

[0050] An embodiment of the present application also provides a breathing mask, which comprises a mask body, a breather tube, and the pinch buckle 10. The breather tube is connected to the mask body through a connecting seat, the mask body is provided with a buckle groove 21, and the connecting arm 200 is connected to the connecting seat.

[0051] In this embodiment, when the pressing portion 120 is pressed, the connecting arm 200 is inclined or bent by a certain angle, so that the buckling portion 110 is buckled into the buckle groove 21 of the first connecting piece 20, and the breather tube and the mask body are connected. At the same time, when the pressing portion 120 is pressed, the supporting arm 300 can be supported between the connecting arm 200 and the pressing portion 120 to prevent the connecting arm 200 and the pressing handle 100 from being broken when the pressing handle 100 is pressed too hard, thereby reducing the damage to the pinch buckle 10 and prolonging the service life.

[0052] In some embodiments, the number of the pinch buckles 10 is two, the two pinch buckles 10 are symmetrically arranged on the two sides of the connecting seat along the radial direction, and the buckle groove 21 is a ring-shaped buckle groove 21, and the two pinch buckles 10 are simultaneously buckled into the ring-shaped buckle groove 21.

[0053] The buckling part 110 of the pinch buckle 10 can exert a pressure in the radial direction on the buckle groove 21. Since the two pinch buckles 10 are symmetrically arranged on the two sides of the connecting seat along the radial direction, i.e., the forces of the two buckling parts 110 are located on the same straight line, a certain clamping effect can be achieved to prevent the inner buckle from being buckled out of the buckle groove 21. At the same time, the buckling part 110 is located in the buckle groove 21, which can prevent the connecting seat from being separated from the mask body along the axial direction. In addition, the two pinch buckles 10 are symmetrically arranged on the two sides of the connecting seat along the radial direction. When operating, two fingers respectively pinch the pressing parts 120 of the two pressing handles 100, and then simultaneously press inward with force, so that the two buckling parts 110 can move to the side away from each other, and when the pinch buckle 10 is released, the two buckling parts 110 can be simultaneously buckled into the buckle groove 21 to connect the breathing tube and the mask body.

[0054] The technical features of the above-mentioned embodiments can be combined arbitrarily. In order to make the description simple, all possible combinations of the technical features in the above-mentioned embodiments are not described, but as long as the combination of the technical features does not exist contradictory, it should be considered as the scope of the present application.

[0055] The above-mentioned embodiments only express several implementation manners of the present application, and the description is more specific and detailed, but it should not be understood as a limitation on the patent scope of the application. It should be pointed out that for ordinary skilled in the art, without departing from the concept of the present application, a number of modifications and improvements can be made, which are all within the protection scope of the present application. Therefore, the patent protection scope of the present application should be subject to the appended claims.
