Description

Technical Field

[0001] This utility model relates to the field of anti-toxic protection devices, and in particular to a glasses mounting bracket for an air-breathing mask and an air-breathing mask. Background Technology

[0002] An air respirator is a type of personal protective equipment. It is a fully enclosed structure that fits snugly against the head of the worker to prevent damage to the respiratory system and eyes in working environments containing high concentrations of toxic gases and solid dust, such as underground oil wells, mines, or underground water systems. However, the limited space inside existing air respirators means that nearsighted individuals cannot wear their glasses while wearing the respirator, making it difficult to see the situation clearly and posing a significant safety hazard.

[0003] Chinese utility model patent CN202459892U discloses an eyeglass frame for an air respirator. Two support rods are installed inside the mask. A bracket with slots corresponding to the shape of the support rods is used. The support rods are embedded in the slots of the bracket, which then moves the bracket up and down. The bracket also has mounting slots for mounting prescription glasses. Lenses are configured and customized according to the operator's degree of myopia. The prescription glasses are then installed on the bracket to achieve the purpose of installing prescription glasses inside the air respirator mask, solving the problem in existing technologies where operators cannot wear glasses after equipping the air respirator mask. However, this technical solution has a problem: the bracket moves up and down along the support rods via the slots and cannot be fixed at a fixed height, which may cause the glasses to fall off during actual use.

[0004] Chinese utility model patent CN209662481U discloses a gas mask eyeglass frame assembly. A suspension boss is provided on the inner side of the gas mask, and a fixing rod is hung on the suspension boss. The fixing rod has vertically arranged toothed grooves on one side in the front-rear direction, and a fall-prevention boss on the other side. A sliding seat is installed on the fixing rod from top to bottom. The design also includes a specially designed lens holder and lens, respectively installed on the left and right sides of the sliding seat. The sliding seat also has a check valve structure, allowing downward movement but preventing upward movement. The lens holder, with the pre-installed lens, is installed on the sliding seat, and the sliding seat is adjusted to a suitable position for normal use. If the lens holder accidentally slips, the anti-fall protrusion can prevent the lens holder from detaching from the fixing rod, solving the problem that the above-mentioned technical solutions cannot fix the position of the lens and cannot prevent the glasses from falling off. However, this solution has a problem: the sliding seat can only move from top to bottom along the fixing rod. If the lens height is too low, the sliding seat must be completely disassembled and the height readjusted, which is complicated. The lens holder in this technical solution cannot be adjusted in the front-to-back direction, and the distance between the lens and the worker's eyes cannot be adjusted. If the distance is too large, the worker will not be able to see the situation clearly. In addition, due to the air-breathing mask's seal, the worker cannot wipe away sweat during the operation. Sweat flowing into the eyes will affect vision and cause poor comfort. Utility Model Content

[0043] The features and performance of this utility model will be further described in detail below with reference to the embodiments.

[0044] The principle and concept of this utility model is as follows: a fixed frame is vertically installed in the middle of the inner side of the breathing apparatus lens. A flexible metal strip is also provided on the fixed frame. The flexible metal strip can be bent into a certain shape and maintain that shape. The flexible metal strip is mounted on the fixed frame through mounting blocks provided at both ends. At least one of the two mounting blocks is movably mounted on the fixed frame. By adjusting the distance between the two mounting blocks, the bending and extension of the flexible metal strip in the front-back direction can be controlled. The glasses can be mounted on the flexible metal strip through a specific carrier, thereby adjusting the position of the glasses in the front-back direction. In summary, the breathing apparatus and glasses holder for breathing apparatus provided by this utility model solve the problem in the prior art that breathing apparatus with glasses mounting brackets cannot adjust the position of the glasses in the front-back direction.

[0045] Based on the above principles and concepts, this utility model provides a glasses mounting bracket for an air-breathing mask and several embodiments thereof for further explanation.

[0046] Based on the above principles, in a basic embodiment, such as Figure 1-8The provided embodiment includes a fixed frame vertically mounted inside the face shield 1, with a built-in adjustment bracket 2 mounted on the fixed frame. The fixed frame can be a frame consisting of two support rods arranged left and right, positioned in the middle of the inner side of the face shield, as used in the Chinese utility model patent CN202459892U, where the mounting block can move up and down along the two support rods without rotating. Alternatively, the fixed frame can be a single non-cylindrical column vertically positioned in the middle of the inner side of the face shield, with the mounting block having mounting holes corresponding to the shape of the column for insertion. The built-in adjustment bracket 2... The device includes upper and lower mounting blocks 3 mounted on a fixed frame and a flexible metal connecting strip 4 connecting the upper and lower mounting blocks 3. At least one of the upper and lower mounting blocks 3 is movably mounted on the fixed frame. When the distance between the upper and lower mounting blocks 3 changes, the flexible metal connecting strip 4 can bend and deform in the front-back direction and maintain the deformed shape. A support member 5 for supporting the installation of eyeglasses is also installed in the middle area of ​​the flexible metal connecting strip 4. After the eyeglasses are installed on the support member 5, the position of the eyeglasses in the front-back direction can be controlled by adjusting the degree of bending of the flexible metal connecting strip 4, which improves the adjustability of the eyeglasses mounting frame for the air-breathing mask and the adjustment method is simple, thus improving the overall wearing comfort of the air-breathing mask.

[0047] Based on the above embodiments, in one embodiment, such as Figure 1-8 In the provided embodiment, the carrier 5 is adjustablely mounted on the flexible metal connecting strip 4 along its length. By adjusting the position of the carrier 5 on the flexible metal connecting strip 4, the position of the glasses in the height direction can be adjusted. This configuration of the carrier 5 increases the adjustment range of the glasses, allowing for arbitrary adjustments within a certain range in the up-down and front-back directions, meeting the diverse glasses position requirements of different wearers and improving the wearing comfort of the breathing mask. In another embodiment, the carrier 5 is fixedly mounted on the flexible metal connecting strip 4, and the height of the carrier 5 can be adjusted by adjusting the curvature of the flexible metal strip 4 in different directions.

[0048] Based on the above embodiments, in one embodiment, such as Figure 1-8In the provided embodiment, multiple snap-fit ​​structures are evenly arranged on the flexible metal connecting strip 4. The carrier 5 has a buckle 6 that cooperates with the snap-fit ​​structure. The carrier 5 is slidably installed on the flexible metal connecting strip 4 along its length direction and can be fixed on the flexible metal connecting strip 4 by the snap-fit ​​of the buckle 6 and the snap-fit ​​structure. In this way, the buckle 6 and the snap-fit ​​structure limit the carrier 5, which can more stably fix the carrier 5 at a certain height. Moreover, the height of the carrier 5 can be changed by simply snapping the carrier 5 into different snap-fit ​​structures, which is convenient for the user to adjust. In another embodiment, the outer surface of the flexible metal connecting strip 4 is a rough surface with high damping. The carrier 5 is inserted into the flexible metal connecting strip 4, and the carrier 5 is fixed at a certain height by the friction between the rough surface of the flexible metal connecting strip 4 and the carrier 5.

[0049] Based on the above embodiments, in one embodiment, such as Figure 1-8 In the provided embodiment, the flexible metal connecting strip 4 includes a pair of locking strips 41 arranged on the left and right sides. The gap between the two locking strips 41 forms a guide slide 7. Symmetrical wave surfaces are provided on the surfaces of the two locking strips 41 facing each other. The crests and troughs on the symmetrical wave surfaces form a locking structure. The buckle 6 is an elastic buckle, including a slider and elastic clips provided on both sides of the slider. The slider is slidably installed in the guide slide 7 and is locked in place by engaging with the wave surface through the elastic clips. In another embodiment, a cuboid flexible metal connecting strip is used as a guide slide rail. The buckle 6 is an annular buckle. The annular buckle has a square hole for the buckle to pass through on the cuboid flexible metal connecting strip. Each of the four hole surfaces of the annular buckle has a centripetal elastic push rod. The annular buckle is passed through the cuboid flexible metal connecting strip and the buckle 6 is fixed at any position on the cuboid flexible metal connecting strip by the elastic push rod.

[0050] Based on the above embodiments, in one embodiment, such as Figure 1-8In the provided embodiment, the carrier 5 includes a carrier frame 51 adapted to the shape of the eyeglass frame. During use, the carrier frame 51, adapted to the shape of the eyeglass frame, will not obstruct the wearer's vision. The carrier frame 51 is detachably connected to the buckle 6. The carrier frame 51 is made of magnetic material to magnetically engage with the eyeglass frame. After removing the temples of the eyeglasses, the frame body is magnetically attached to the carrier frame 51. In this way, the carrier frame 51 and the eyeglass frame are magnetically connected, allowing workers to more quickly and conveniently assemble and disassemble the eyeglass frame during actual use. After adjusting the carrier frame 51 to the appropriate position, the eyeglass frame is then attached to the carrier frame 51. After wearing the breathing mask, the eyeglass frame is removed and the temples are installed, allowing it to be used normally as everyday glasses. In another embodiment, through holes are provided on both sides of the carrier frame 51, and mounting holes are provided at the corresponding positions of the through holes on the eyeglass frame and the carrier frame 51. The eyeglass frame is fixed to the carrier frame 51 by bolts and nuts.

[0051] Based on the above embodiments, in one embodiment, such as Figure 1-8 In the provided embodiment, the buckle 6 is provided with a magnetic adsorption point, and the carrier frame 51 is magnetically connected to the buckle 6. The carrier frame 51 connected by magnetic attraction can be pre-adjusted to the position of the buckle 6 before being adsorbed onto the buckle 6. The magnetic attraction can also enable quick assembly and disassembly of the carrier frame 51, improving the convenience of the air-breathing mask. In another embodiment, the buckle 6 is provided with a mounting groove, and a mounting block is installed on the middle crossbeam of the carrier frame 51. The carrier frame 51 is fixed to the buckle 6 by the engagement of the mounting block and the mounting groove.

[0052] Based on the above embodiments, in one embodiment, such as Figure 1-8 In the provided embodiment, a horizontal mounting strip 8 is also installed on the built-in adjustment bracket 2 above the support member 5 for installing the sweat-absorbing cotton strip 9. The horizontal mounting strip 8 is installed at the user's forehead to facilitate the absorption of the user's sweat in hot working conditions and prevent sweat from entering the eyes and affecting vision.

[0053] Based on the above embodiments, in one embodiment, such as Figure 1-8 In the provided embodiment, the aforementioned horizontal mounting strip 8 is installed on the upper surface of the support frame 51, and a sweat-absorbing cotton strip 9 is installed on the horizontal mounting strip 8. Since the support frame 51 is closest to the user's eyes, installing the horizontal mounting strip 8 at the upper end of the support frame 51 facilitates the adjustment of the distance between the sweat-absorbing cotton strip 9 and the user's forehead, simplifying the adjustment process. In another embodiment, a second buckle is installed in the guide slide 7 at the upper side of the support member 5. The horizontal mounting strip 8 is made of magnetic material, and the second buckle is provided with magnetic adsorption points. The horizontal mounting strip 8 is magnetically connected to the second buckle, and the position of the sweat-absorbing cotton strip is adjusted by adjusting the position of the second buckle.

[0054] Based on the above embodiments, in one embodiment, such as Figure 1-8 In the provided embodiment, the horizontal mounting strip is adjustable in the vertical direction and installed above the support frame; in another embodiment, the bottom of the horizontal mounting strip 8 is provided with a mounting rod of fixed length, and both ends of the mounting rod are provided with clamping structures. The horizontal mounting strip 8 is installed above the support frame by the mounting rod, and the height of the horizontal mounting strip 8 can be controlled by changing the mounting rod of different lengths.

[0055] Based on the above embodiments, in one embodiment, such as Figure 1-8 In the provided embodiment, the horizontal mounting strip 8 is mounted above the support frame 51 via a telescopic bracket 10, and the height of the horizontal mounting strip 8 is adjusted by adjusting the length of the telescopic bracket. In another embodiment, a rigid plastic corrugated tube is used as a connector for mounting the horizontal mounting strip 8 above the support frame 51. The height of the horizontal mounting strip 8 is controlled by controlling the folding and extension of the rigid plastic corrugated tube. The rigid plastic corrugated tube can not only adjust the height but also provide a variety of bending angles, providing the wearer with a greater range of adjustment. Since the rigid plastic corrugated tube has limited load-bearing capacity, it may detach and bend when the worker's face is facing down, causing the sweat-absorbing cotton strip 9 to detach from the worker's forehead. Therefore, when using a rigid plastic corrugated tube as a bracket for the horizontal mounting strip 8, the support frame 5 can only be mounted on the buckle 6 from the wearer's direction towards the face shield, with the built-in adjustment bracket 2 providing auxiliary support for the horizontal mounting strip 8 to prevent the sweat-absorbing cotton strip 9 from detaching from the wearer's forehead.

[0056] Based on the above embodiments, in one embodiment, such as Figure 1-8 In the provided embodiment, the inner side of the horizontal mounting strip 8 is an adaptive curved surface for fitting the user's forehead; in another embodiment, the horizontal mounting strip 8 is a cuboid structure, and the sweat-absorbing cotton strip 9 mounted on the horizontal mounting strip 8 has an adaptive curved surface for fitting the user's forehead.

[0057] Based on the above embodiments, in one embodiment, such as Figure 1-8 In the provided embodiment, the inner side of the horizontal mounting strip 8 has an adhesive surface for attaching the sweat-absorbing cotton strip 9, and the sweat-absorbing cotton strip 9 is attached to the horizontal mounting strip 8 by double-sided adhesive; in another embodiment, a magnetic adsorption point is provided on the side of the horizontal mounting strip 8 facing the user, and a magnet is installed on the opposite side of the side of the sweat-absorbing cotton strip 9 facing the user, so that the sweat-absorbing cotton strip 9 is magnetically attached to the horizontal mounting strip 8.

[0058] This utility model also provides an air-breathing mask, including a mask lens 1 and an eyeglass mounting frame installed inside the mask lens 1. The eyeglass mounting frame is the eyeglass mounting frame for air-breathing masks provided in the above embodiments, which will not be described in detail here.

[0059] The eyeglasses mounting bracket for the breathing apparatus provided by this utility model and the breathing apparatus itself are used as follows: First, a fixed support is installed inside the mask goggles 1. Then, two clips 41 are installed onto the fixed support via two mounting blocks 3. The elastic clips on both sides of the elastic buckle are retracted, and the buckle 6 is installed in the guide slide 7. Finally, the entire support frame 51 with the sweat-absorbing cotton strips 9 installed is magnetically fixed onto the buckle 6, completing the installation of the eyeglasses mounting bracket for the breathing apparatus. Finally, the user's glasses are magnetically attached to the support frame 51. The support frame can be adjusted up or down according to the user's needs. By adjusting the height of the horizontal mounting strip 8 in the forward and backward directions, and adjusting the sweat-absorbing cotton strip 9 to a suitable position, the adjustment range of the glasses position in the air-breathing mask that can accommodate glasses is greatly improved. At the same time, a sweat-absorbing cotton strip 9 is provided at the upper end of the support frame 51 to absorb sweat, preventing sweat from flowing into the user's eyes. In summary, the glasses mounting bracket for air-breathing masks provided by this utility model improves the overall comfort of air-breathing masks and solves the problem that glasses in existing air-breathing masks that can accommodate glasses cannot be adjusted in the forward and backward directions, resulting in poor user comfort.
