[0023] In order to make the purpose, technical solution and advantages of this application clearer, the technical solution in the embodiment will be clearly and completely described below in conjunction with the drawings in the embodiment. Obviously, the described embodiment is only a part of the embodiment of this application, not all embodiments. Based on the given embodiments, all other embodiments obtained by ordinary technicians in this field without making creative work are within the scope of protection of this application.

[0024] In the description of the present application, it should be understood that the terms "upper", "lower", etc. indicate orientations or positional relationships based on the orientations or positional relationships shown in the accompanying drawings, and are only for the convenience of describing the present application and simplifying the description, rather than indicating or implying that the device or element referred to must have a specific orientation, be constructed and operated in a specific orientation, and therefore should not be understood as a limitation on the present application.

[0025] In the description of this application, the terms "first", "second", etc. are used for descriptive purposes only and cannot be understood as indicating or implying relative importance or implicitly indicating the number of the indicated technical features.

[0026] The invention discloses a mask anti-strangulation device. When in use, a mask rope (not shown in the figure) on a mask (not shown in the figure) is passed through the mask anti-strangulation device and then hung on the ear of a human body, so as to solve the discomfort existing in the prior art that the ear is tightly strangled by the mask rope after wearing the mask, and can improve the wearing comfort; on the other hand, the use length of the mask rope can also be adjusted.

[0027] The present invention discloses a mask strangulation protector, comprising a main body 1 for wearing on the ear. As shown in the figure, its inner contour 1a is adapted to the auricle of the human body, so that the mask strangulation protector can be hung on the ear and worn on the ear. Since the main body 1 has a larger force-bearing surface relative to the mask rope when worn, the wearing comfort is improved.

[0028] See also Figure 1 , the main body 1 is provided with two clamping structures 2 for clamping the mask rope. In specific applications, after the clamping structure 2 clamps the mask rope, the clamping structure 2 and the mask rope are relatively fixed and locked. By using the two clamping structures 2 in coordination, the use length of the mask rope can be adjusted. Specifically, for wearing needs, when a relatively shorter mask rope is needed, the mask rope clamped between the two clamping structures 2 is relatively longer, and the mask rope remaining outside the mask anti-strangulation device is relatively shorter; when a relatively longer mask rope is needed, the mask rope clamped between the two clamping structures 2 is relatively shorter, and the mask rope remaining outside the mask anti-strangulation device is relatively longer. Even the mask rope between the two clamping structures 2 is clamped and locked in a tightened manner, so that a longer mask rope can be obtained. Therefore, a mask anti-strangulation device using this structure can meet a variety of usage needs.

[0029] In the present invention, in order to facilitate the lengthening of the mask string, at least one of the two clamping structures 2 is a push-type clamp 20, which often clamps the mask string and locks it. When the push-type clamp 20 is pressed, the push-type clamp 20 releases the lock on the mask string. It should be pointed out that in the description of the present invention, the constant clamping refers to the locking state of the mask string by the push-type clamp 20 when the push-type clamp 20 is not pressed.

[0030] See also Figure 1 , Figure 3 The main body 1 is provided with a rope groove 11, and the two clamping structures 2 are respectively located at one end of the rope groove 11. In this embodiment, the rope groove 11 is for the mask rope to pass through. Usually, a recessed groove 112 is provided on the right side wall 111 of the rope groove 11 to prevent the mask rope from falling out of the rope groove 11.

[0031] It should be noted that in this embodiment, both clamping structures 2 use a press-type clamp 20. As another embodiment, the two clamping structures 2 may be one of which uses a press-type clamp 20 structure, and the other uses, for example, a press plate structure that fits tightly with the rope groove 11 or other structures that can fix the mask rope to the main body 1.

[0032] See also Figure 4 In this embodiment, the push-type clamp 20 includes a fixed block 21, a sliding block 22 and a compression spring (as shown in the figure). The fixed block 21, the sliding block 22 and the compression spring can cooperate to achieve the use states of normal clamping and unlocking by pressing the sliding block 22. When in normal clamping, the push-type clamp 20 and the mask rope are fixed and locked; when in the release of normal clamping, the mask rope is released by the push-type clamp 20 and can move relative to the push-type clamp 20.

[0033] In the present invention, the press-type clamp 20 can lengthen the mask strap by pressing, and can be easily adjusted even after wearing, which is simple and convenient to operate.

[0034] like Figure 4 , Figure 5 As shown in , the fixing block 21 is provided with a through slot 30 intersecting with the rope slot 11, and the through slot 30 has an open mouth 31, and the open mouth 31 faces outward, so that after the fixing block 21 is assembled to the main body 1, the mask rope can directly enter the through slot 30 through the rope slot 11 and the open mouth 31. Figure 5 The fixing block 21 includes an upper plate 211, a lower plate 212 and a rear plate 213. One edge of the upper plate 211 is connected to an upper edge of the rear plate 213, and the lower edge of the rear plate 213 is connected to an edge of the lower plate 212. There is a space 215 between the upper plate 211 and the lower plate 212. The upper plate 211 is provided with an upper notch 32, and the lower plate 212 is provided with a lower notch 33. The upper notch 32, the lower notch 33 and the space 215 are used to construct the through groove 30.

[0035] like Figure 4 As shown, the space 215 between the upper plate 211 and the lower plate 212 is provided for the sliding block 22 to be inserted, whereby the sliding block 22 is slidably connected to the fixed block 21. When the fixed block 21 and the sliding block 22 are specifically assembled, the sliding block 22 is inserted from the side where the open mouth 31 is located.

[0036] A clamping part 14 for clamping the mask string is fixed on the sliding block 22. The compression spring is arranged between the sliding block 22 and the fixed block 21, and the compression spring presses the sliding block 22 to push the clamping part 14 toward the fixed clamping part 25 for clamping the mask string.

[0037] In this embodiment, see Figure 5The sliding block 22 has a head, and the upper corner 2211 and the lower corner 2212 on the head form the clamping part 1 4. The lower corner 321 on the upper notch 32 and the upper corner 331 of the lower notch 33 form the clamping part 2 5.

[0038] In another embodiment, as the implementation structure of the clamping part 1 4, it is the upper corner 2211 on the head, and as the implementation structure of the clamping part 2 5, it is the lower corner 311 on the upper notch 32. In yet another embodiment, as the implementation structure of the clamping part 1 4, it is the lower corner 2212 on the head, and as the implementation structure of the clamping part 2 5, it is the upper corner 331 of the lower notch 33.

[0039] In the above structure, the overall force-bearing surface of the above-mentioned part used to clamp the mask rope is small, so that the mask rope can be firmly locked to prevent the mask rope from loosening during wearing.

[0040] In specific applications, when no pressing is performed, the sliding block 22 is acted upon by the compression spring, so that the clamping part 1 4 and the clamping part 2 5 can approach each other and clamp the mask rope, forming a locked state; when pressing is performed on the sliding block 22, the sliding block 22 moves in the direction of the compression spring, and the clamping part 1 4 and the clamping part 2 5 move away from each other and release the mask rope, forming an unlocked state.

[0041] In this embodiment, a limit block 23 is provided on the upper part and / or the lower part of the sliding block 22, and the left groove wall 34 of the through groove 30 is used to abut against the limit block 23. By adopting this structure, when the mask anti-strangulation device of this embodiment is not used with a mask, the sliding block 22 will not be pressed by the compression spring and directly detach from the fixed block 21.

[0042] In one embodiment, the upper notch 32 and / or the lower notch 33 are correspondingly provided with a recessed opening 35 for accommodating the stopper 23. By providing the structure of the recessed opening 35, the head can give up more space, so that the through slot 30 can be fully opened to facilitate the insertion of the mask string.

[0043] In this embodiment, the fixing block 21 and the main body 1 are separate structures, see Figure 3 The main body 1 is provided with a receiving cavity 12, which runs through the rope groove 11 transversely, and the receiving cavity 12 is provided with an open end 121 for the fixed block 21 to be inserted, and an end of the sliding block 22 away from the compression spring is exposed to the open end 121; the fixed block 21 is provided with a clamping block 6, and the groove wall of the rope groove 11 is abutted by the first clamping block 6 to prevent the fixed block 21 from escaping from the receiving cavity 12. By adopting this structure, the fixed block 21 can be fixed without other fasteners when assembling the fixed block 21 and the main body 1.

[0044] In one embodiment, the upper plate 211 and the lower plate 212 are provided with the block 6, and the block 6 is relatively far away from the rear plate 213, and the block 6 is integrally formed with the fixing block 21. In another embodiment, the block 6 is provided on the upper plate 211 or the lower plate 212.

[0045] Since the clamping block 6 is relatively far away from the rear plate 213 , during the assembly process of the fixing block 21 and the main body 1 , the location of the clamping block 6 is compressed and can cause relatively large elastic deformation, so that the fixing block 21 can be assembled with the main body 1 .

[0046] In one embodiment, a rope guard plate is provided on the main body 1, and the rope guard plate extends into the rope groove 11. By providing the structure of the rope guard plate, the mask rope can be effectively prevented from falling out.

[0047] In one embodiment, the head is provided with a receiving groove 25 for receiving the compression spring, and the fixing block 21 further includes a right plate 214, which is fixed to the right side of the upper plate 211, and a positioning column for the compression spring to be sleeved is provided on the right plate 214. The compression spring is positioned by providing the receiving groove 25 and the positioning column structure.

[0048] The above embodiments are only preferred embodiments of the present invention and are not intended to limit the protection scope of the present invention. Therefore, any equivalent changes made based on the structure, shape, and principle of the present invention should be included in the protection scope of the present invention.
