Description

Technical Field

[0001] The utility model relates to the technical field of face masks, in particular to a new plastic face mask. Background Art

[0002] During some special chemical operations, material splashing may occur. When the material splashes onto a person's face, it will cause serious harm to the operator. Therefore, it is necessary to wear a face mask during the operation. The face mask can protect the face and eyes, thus improving the safety during the operation. The plastic face mask has high strength and good elasticity, so it is widely used. Most plastic face masks are composed of a protective face mask and a fixing component. The protective face mask can be fixed on the head through the fixing component, and the face can be shielded and protected through the protective face mask.

[0003] However, the protective face mask and the fixing component of the traditional plastic face mask form a whole. Therefore, when the face mask is damaged, the whole face mask needs to be replaced, which will increase the use cost.

[0004] Therefore, it is necessary to design a face mask with an assembled structure. Summary of the Utility Model

[0005] In order to solve the above problems, the utility model provides a new plastic face mask. When the protective face mask is damaged, it only needs to be disassembled and replaced separately, instead of replacing the whole face mask, thus effectively reducing the use cost.

[0006] In order to achieve the above purpose, the utility model adopts the following technical solutions:

[0007] A new plastic face mask, including a protective face mask, a connecting ring is rotatably connected to the protective face mask, two connecting blocks are rotatably connected to the connecting ring, a resisting block is engaged with the connecting block, a clamping structure is arranged on the resisting block, the clamping structure includes a pressing block and a guiding groove, the pressing block is slidably connected to the resisting block, four guiding grooves are arranged on the pressing block, two clamping blocks are slidably connected to the resisting block, one end of the clamping block is engaged with the connecting block, a guiding shaft is fixedly connected to the clamping block, two ends of the guiding shaft extend into the adjacent two guiding grooves and are slidably connected with the pressing block, and two first springs are arranged inside the resisting block.

[0008] Optionally, in an embodiment of the utility model, one end of the first spring is fixedly connected to the pressing block, and the other end of the first spring is fixedly connected to the resisting block.

[0009] Optionally, in an embodiment of the utility model, the whole cross-section of the resisting block is in a T-shaped structure, and the cross-section of one end of the resisting block is in a trapezoidal structure.

[0010] Optionally, in an embodiment of the present utility model, a V-shaped structure is formed between two adjacent guiding grooves, and the cross-section of one end of the clamping block is in a trapezoidal structure.

[0011] Optionally, in an embodiment of the present utility model, a fixing ring is fixedly connected to the connecting ring, a first connecting band is fixedly connected to one end of the connecting ring, and a second connecting band is fixedly connected to the other end of the connecting ring.

[0012] Optionally, in an embodiment of the present utility model, a hook surface of a magic tape is fixedly connected to the first connecting band, and a loop surface of the magic tape is fixedly connected to the second connecting band.

[0013] Optionally, in an embodiment of the present utility model, a limiting structure is provided on the connecting ring. The limiting structure includes a limiting block and a second spring. A plurality of limiting blocks are slidably connected to the connecting ring. One end of the limiting block is engaged with the connecting block, and the same number of second springs as the limiting blocks are provided inside the connecting ring.

[0014] Optionally, in an embodiment of the present utility model, one end of the second spring is fixedly connected to the limiting block, and the other end of the second spring is fixedly connected to the connecting ring.

[0015] Optionally, in an embodiment of the present utility model, the cross-section of the connecting block is in a T-shaped structure, and the cross-section of one end of the limiting block is in a semi-circular structure.

[0016] Advantages of the Present Utility Model

[0017] For a new type of plastic face mask of the present utility model, when the protective face mask needs to be replaced, two pressing blocks can be pressed simultaneously. The movement of the pressing blocks will drive the movement of the four guiding grooves, so that the guiding shaft moves inside the guiding grooves. While the guiding shaft moves inside the guiding grooves, the clamping block moves away from the connecting block. When the clamping block and the connecting block are not engaged, the abutting block can be moved to separate it from the connecting block. After the abutting block and the connecting block are separated, the protective face mask will not be blocked. Then, the protective face mask can be removed from the connecting ring, thus realizing the disassembly of the protective face mask. Therefore, when the protective face mask is damaged, only the protective face mask needs to be replaced separately, instead of the whole replacement, which effectively reduces the use cost.

Detailed implementation manners

[0025] To further elaborate on the technical means and effects adopted by the present utility model to achieve the predetermined utility model purpose, the following, in conjunction with the accompanying drawings and preferred embodiments, details the specific implementation manners, structures, features and their effects of the present utility model as follows. Embodiment 1

[0026] In order to reduce the use cost of the protective mask, a new type of plastic mask is designed, and the specific scheme is as follows:

[0027] As Figures 1-5 shown, a new type of plastic mask includes a protective mask 1, a connecting ring 2 is rotatably connected to the protective mask 1, two connecting blocks 5 are rotatably connected to the connecting ring 2, an abutting block 3 is clamped on the connecting block 5, a clamping structure 4 is arranged on the abutting block 3, the clamping structure 4 includes a pressing block 401 and a guiding groove 402, a pressing block 401 is slidably connected to the abutting block 3, four guiding grooves 402 are arranged on the pressing block 401, two clamping blocks 404 are slidably connected to the abutting block 3, one end of the clamping block 404 is clamped with the connecting block 5, a guiding shaft 403 is fixedly connected to the clamping block 404, and both ends of the guiding shaft 403 extend into the interiors of two adjacent guiding grooves 402 and are slidably connected to the pressing block 401, and two first springs 405 are arranged inside the abutting block 3.

[0028] As Figure 3 shown, one end of the first spring 405 is fixedly connected to the pressing block 401, the other end of the first spring 405 is fixedly connected to the abutting block 3, the overall cross-section of the abutting block 3 is in a T-shaped structure, and the cross-section of one end of the abutting block 3 is in a trapezoidal structure, so that the pressing block 401 can be reset under the action of the first spring 405.

[0029] AsFigure 3 As shown, a V-shaped structure is formed between two adjacent guiding grooves 402, and the cross-section of one end of the clamping block 404 is trapezoidal, so it plays a guiding role when the clamping block 404 is engaged with the connecting block 5.

[0030] As Figure 1 shown, a fixing ring 7 is fixedly connected to the connecting ring 2. One end of the connecting ring 2 is fixedly connected to a first connecting band 8, and the other end of the connecting ring 2 is fixedly connected to a second connecting band 10. A hook-and-loop fastener rough surface 9 is fixedly connected to the first connecting band 8, and a hook-and-loop fastener hook surface 11 is fixedly connected to the second connecting band 10. Therefore, the protective face mask 1 can be fixed on the head.

[0031] As Figure 3 shown, a limiting structure 6 is provided on the connecting ring 2. The limiting structure 6 includes a limiting block 601 and a second spring 602. A plurality of limiting blocks 601 are slidably connected to the connecting ring 2. One end of the limiting block 601 is engaged with the connecting block 5. The same number of second springs 602 as the limiting blocks 601 are provided inside the connecting ring 2. One end of the second spring 602 is fixedly connected to the limiting block 601, and the other end of the second spring 602 is fixedly connected to the connecting ring 2. The cross-section of the connecting block 5 is T-shaped, and the cross-section of one end of the limiting block 601 is semi-circular. Therefore, it can prevent the protective face mask 1 from rotating under the action of its own gravity, thereby improving the stability of use.

[0032] Working principle:

[0033] During use, the connecting ring 2 can be brought into contact with the front end of the head, and then the first connecting band 8 and the second connecting band 10 are wound around the rear end of the head, and the hook-and-loop fastener rough surface 9 and the hook-and-loop fastener hook surface 11 are adhered to each other, so as to fix the connecting ring 2. By setting the fixing ring 7, the stability during fixation can be increased. During use, the protective face mask 1 can be used to shield and protect the face, thereby avoiding facial injuries. When the protective face mask 1 is temporarily not needed, the protective face mask 1 can be rotated to the top of the head. When the protective face mask 1 rotates to a certain state, the end of the limiting block 601 can be engaged with the connecting block 5 under the action of the second spring 602, thereby preventing the connecting block 5 from rotating. If the connecting block 5 does not rotate, the protective face mask 1 will not rotate either, thereby preventing the protective face mask 1 from rotating after the hand is released, thereby improving the stability of use.

[0034] When the protective face shield 1 is damaged and needs to be replaced, by pressing two pressing blocks 401 simultaneously, the first spring 405 contracts, and the movement of the pressing blocks 401 drives the movement of the four guiding grooves 402, so that the guiding shaft 403 moves inside the guiding grooves 402. While the guiding shaft 402 moves inside the guiding grooves 403, the clamping block 404 moves away from the connecting block 5. When the clamping block 404 is not engaged with the connecting block 5, the abutting block 3 can be moved to separate it from the connecting block 5. After the abutting block 3 is separated from the connecting block 5, it will no longer resist the protective face shield 1. Then, the protective face shield 1 can be removed from the connecting ring 2, thus realizing the disassembly of the protective face shield 1. Therefore, when the protective face shield 1 is damaged, only the protective face shield 1 needs to be replaced individually, rather than the whole, effectively reducing the use cost.
