[0029] Embodiment 1

[0030] This embodiment discloses a mask strangulation preventer, including a body 1 for hanging on the ear. In a specific application, the body 1 is hooked on the human ear. In this embodiment, the body 1 includes a main body 11 and a buckle cover 12. As shown in the figure, the inner curve of the main body 11 is roughly similar to the curve of the human auricle. Therefore, when the main body 11 is hooked on the human ear, it has a better comfort.

[0031] like Figure 2 As shown in , the main body 11 and the buckle cover 12 are formed separately, and the buckle cover 12 is buckled on the main body 11.

[0032] The main body 11 and the buckle cover 12 form a chamber 2 for the limited sliding of the sliding block 3, and the chamber 2 has an open end 21, and the open end 21 allows one end 3a of the sliding block 3 to be exposed. In specific applications, one end 3a of the sliding block 3 is used for a finger to press the sliding block 3 to release the clamping fixation of the mask rope.

[0033] See also Figure 1 , Figure 2 The main body 11 is provided with a wire groove 111, the buckle cover 12 is provided with an open mouth 121 connected with the wire groove 111, and the sliding block 3 is fixed with a wire clamping part 1 41 for clamping the mask rope. In this embodiment, the wire clamping part 1 41 and the sliding block 3 are integrally formed. The chamber 2 is fixed with a wire clamping part 2 42, and the open mouth 121 is for the mask rope to pass through and is placed between the wire clamping part 1 41 and the wire clamping part 2 42. The wire clamping part 1 41 (not shown in the figure) that moves with the sliding block 3 is pushed toward the wire clamping part 2 42 by a spring, thereby clamping and fixing the mask rope. Figure 2 As shown in the figure, the clamping part 1 41 is formed by a vertically extending corner formed by the intersection of two surfaces on the sliding block 3. The clamping part 2 42 is formed by a vertically extending corner formed by the intersection of two surfaces. Therefore, the parts of the clamping part 1 41 and the clamping part 2 42 used to contact the mask string are both linear structures, so as to avoid the clamped position on the mask string from changing in the clamped state, and the clamping part 1 41 and the clamping part 2 42 can firmly clamp the mask string.

[0034] In one embodiment, the spring adopts the structure of a compression spring, one end of which is against the inner wall 2a of the chamber 2. Usually, a positioning column 24 is provided on the side wall of the chamber 2, on which one end of the compression spring is sleeved to position the spring. The other end of the compression spring is against the sliding block 3. Usually, a compression spring cavity 34 for inserting the compression spring is provided on the sliding block 3. The compression spring is stably assembled by the structure of the positioning column 24 and the compression spring cavity 34. When the finger does not press the sliding block 3, the elastic restoring force of the compression spring is used to make the clamping part 1 41 abut against the clamping part 2 42, so that the mask rope is clamped by the clamping part 1 41 and the clamping part 2 42. Thus, the mask rope is fixed. When the finger presses the sliding block 3, the sliding block 3 moves in the direction of the compression spring. At this time, the clamping part 1 41 and the clamping part 2 42 move away from each other, so that the clamping part 1 41 and the clamping part 2 42 release the clamping fixation of the mask rope, so that the mask rope can move relatively.

[0035] It should be pointed out that in the present invention, the two ends of the main body 11 are respectively provided with a buckle cover 12, a sliding block 3 and other structures, so that a clamping structure 10 is formed at each end of the mask anti-strangulation device. In specific applications, after the clamping structure 10 clamps the mask rope, the clamping structure 10 and the mask rope are relatively fixed and locked. By using two clamping structures 10 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 10 is relatively longer, and the mask rope left 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 10 is relatively shorter, and the mask rope left outside the mask anti-strangulation device is relatively longer. Even, the mask rope between the two clamping structures 10 is clamped and locked in a tightened manner, and a longer mask rope can be obtained. Therefore, a mask anti-strangulation device using this structure can meet a variety of usage needs.

[0036] In one embodiment, a limit block 51 is provided on the side of the sliding block 3, and a limit fitting portion 52 is provided in the chamber 2, and the limit fitting portion 52 is used to abut against the limit block 51. In this embodiment, the sliding distance of the sliding block 3 in the chamber 2 is limited by the structure of the limit block 51 and the limit fitting portion 52, so as to prevent the sliding block 3 from escaping from the chamber 2 when it is not used with a mask. Usually, when the clamping portion 1 41 and the clamping portion 2 42 clamp the mask rope, it is preferred that the limit block 51 and the limit fitting portion have a micro-spacing or just contact. In this embodiment, the limit fitting portion 52 is located below the clamping portion 2 42, the limit fitting portion 52 and the clamping portion 2 42 are an integral structure, and the limit block 51 and the sliding block 3 are an integrally formed structure.

[0037] See also Figure 2 , Figure 5 , Figure 6The chamber 2 includes a recessed cavity 22 disposed on the main body 11, and the top of the recessed cavity 22 is an open mouth 23. The sliding block 3 is placed into the recessed cavity 22 through the open mouth 23, and the buckle cover 12 is buckled into the open mouth 23. In one embodiment, a mortise 112 is disposed on the main body 11, and a tenon column 122 is disposed on the buckle cover. The tenon column 122 is inserted into the mortise 112 and forms a tight fit, thereby fixing the buckle cover 12 and the main body 11 together. Since the limiting matching part 52, the clamping part 42, and the main body 11 are an integrated structure, the limiting block 51 and the sliding block 3 are integrally formed, which simplifies the structure, and the assembly of the sliding block 3 is made easier by designing the structure of the chamber 2.

[0038] See also Figure 5 The bottom of the recessed cavity 22 is provided with a recessed groove 221, and the side wall of the recessed groove 221 cooperates with the side wall of the sliding block 3 to limit the sliding movement in the width direction of the recessed groove 221. In this embodiment, the sliding block 3 and the recessed groove 221 cooperate to guide the movement of the sliding block 3.

[0039] like Figure 2 As shown in the figure, the buckle cover 12 includes a left cover 123 and a right cover 124, and the left cover 123 and the right cover 124 are connected by a concave connecting portion 125. In this embodiment, the concave connecting portion 125 leaves space for configuring the open mouth 121. Through the structure of the concave connecting portion 125, the buckle cover 12 having both the left cover 123 and the right cover 124 is an integral structure, which can be formed in one step, and is easy to manufacture and assemble.

[0040] See also Figure 2 The sliding block 3 is provided with a wire groove 31, and a wire protection part 32 is provided on the inner side wall 31a of the wire groove 31. The end of the wire protection part 32 is spaced from the outer side wall of the wire groove 31 to form an opening 33. Based on the bending direction of the body 1, in specific applications, the mask rope is close to the inner side wall. Therefore, by setting the structure of the wire protection part 32, the mask rope can be prevented from slipping out at the position of the wire groove 31. After the wire clamping part 1 41 is pushed toward the wire clamping part 2 42 by the spring, the opening 33 is staggered with the open opening 121 and hidden under the buckle cover 12. In this embodiment, the opening 33 is hidden under the right cover 124. When the wire clamping part 1 41 and the wire clamping part 2 42 are in the state of clamping and fixing the mask rope, the opening is closed by the structure of the right cover 124 to further prevent the mask rope from slipping out of the wire groove 31 during use. Of course, as another implementation structure, the opening 33 can also be hidden under the left cover 123. Specifically, the second clamping part 42 is arranged on the left side of the first clamping part 41, and the sliding block 3 slides to the left to clamp the mask rope.

[0041] In this embodiment, the buckle cover 12 is provided with a wire guard plate 61 at the upper position of the inner side wall of the opening 121. The wire guard plate 61 is provided to prevent the mask rope from slipping out of the opening 121. As shown in the figure, a notch 62 is provided on the inner side wall of the opening 121. The notch 62 is provided to prevent slipping out on the one hand, and to chamfer on the other hand.

[0042] It should be pointed out that, in the description of the present application, the inner side wall is defined based on the bending direction of the body 1, and the inner side wall is adjacent to the bending center.

[0043] Embodiment 2

[0044] See also Figure 6 , Figure 7 The structural principle of the mask anti-strangulation device disclosed in this embodiment is the same as that of the first embodiment. The difference between the two is the layout orientation of the wire slot and the components related thereto. In this embodiment, the wire slot 111 is arranged on the back of the main body 11. After the mask anti-strangulation device of this embodiment is worn on the ear, the opening of the wire slot 111 faces backward. When the mask anti-strangulation device is used with a mask, the mask rope abuts against the bottom wall of the wire slot 111, which is more effective in preventing the mask rope from falling out.

[0045] 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.
