Description

TECHNICAL FIELD

[0001] The present application belongs to the technical field of mask equipment, and particularly relates to a manufacturing method of a safety protective mask. BACKGROUND

[0002] In industrial production, the face of a person is often injured by high-speed particles, molten metal, chemical liquid splashing and harmful light, and various protective masks must be used for protection.

[0003] The protective mask is a tool used to protect the face and neck from flying metal debris, harmful gas, liquid splashing, metal and high-temperature solvent flying ends.

[0004] There are many types of protective masks, but they can be generally divided into four types according to their uses, namely, anti-impact masks, anti-corrosive liquid splashing masks, anti-dust, smoke and various toxic gas masks, and anti-radiation masks, and observation windows are provided on these masks.

[0005] In use, the protective mask should be clean and transparent without scratches and cracks. The connection between the mask and the hat rack should be firm. The hat rack strap should be suitable for adjustment so that it is worn on the head with moderate tightness, safety and comfort.

[0006] However, in the prior art, the manufacturing of the protective mask is usually manually assembled by manual assembly, and the manual assembly precision of the protective mask is low, the processing efficiency is low, batch production cannot be realized, and the existing production needs cannot be met. SUMMARY

[0007] The present application aims to solve the above technical problems in the prior art, and provides a manufacturing method of a safety protective mask. The protective mask is manufactured with the aid of an assembly table. First, various parts required for manufacturing the protective mask are prepared, and then the various parts are clamped and fixed. The back of the elastic fixed rear seat is clamped in the turnover clamping assembly of the assembly table with the back facing upwards. The elastic fixed front seat is fixed at the top of the lifting assembly mechanism, and the face transparent cover plate is adsorbed at the bottom of the lifting assembly mechanism. The elastic fixed rear seat is clamped and fixed on the back. The installation of the elastic band is facilitated. After the installation of the elastic band is completed, the turnover clamping assembly drives the elastic fixed rear seat to turn over. Then, the lifting assembly mechanism installs the adsorbed face transparent cover plate on the elastic fixed rear seat. After the lifting assembly mechanism is reset, the elastic fixed front seat is rotated so that the elastic fixed front seat is rotated from the top to the bottom. The elastic fixed front seat is lowered again by the lifting mechanism, so that the face transparent cover plate is fixed between the elastic fixed front seat and the elastic fixed rear seat. Then, the fastening screw is screwed in for fixation. The manufacturing of the protective mask is completed. The manufacturing precision of the protective mask is improved, the manufacturing efficiency of the mask is greatly improved, and batch production of the protective mask is realized.

[0008] In order to solve the above technical problems, the present application adopts the following technical solutions:

[0009] A method for manufacturing a safety protective face shield, the face shield comprising: a transparent face shield, an elastically fixed front seat, and an elastically fixed rear seat, wherein the top of the transparent face shield is fixedly connected between the elastically fixed front seat and the elastically fixed rear seat, and an elastic band is fixedly connected to the rear side of the elastically fixed rear seat; the manufacturing method includes the following steps:

[0010] a. Preparations before production

[0011] First, prepare all the necessary components for manufacturing the protective mask, and then clean and reposition the assembly table required for mask manufacturing.

[0012] b. Clamping

[0013] 1) Clamping of the elastically fixed rear seat

[0014] First, place the elastic fixing rear seat with its back side facing up on the assembly table. Then, the flip-clamping assembly on the assembly table clamps and fixes the elastic fixing rear seat, thus fixing it on the assembly table.

[0015] 2) Clamping of the flexible fixed front seat

[0016] A lifting assembly mechanism is set on one side of the assembly table corresponding to the flip clamping component. The back of the elastic fixed front seat is placed on top of the lifting assembly mechanism with the corresponding elastic fixed rear seat facing upward. The lifting assembly mechanism fixes the elastic fixed front seat.

[0017] 3) Fixation of the transparent facial mask

[0018] Place the transparent face mask face up at the bottom of the lifting assembly mechanism. The lifting assembly mechanism will then attach the transparent face mask to the bottom of the lifting assembly mechanism.

[0019] c. Assembly

[0020] 1) Elastic band assembly

[0021] The operator secures the elastic band to the back of the elastic fixing seat, and then flips the clamping assembly to control the elastic fixing seat with the elastic band to flip so that the front of the elastic fixing seat is facing upwards.

[0022] 2) Assembly of the transparent facial mask

[0023] The lifting assembly mechanism controls the elastic fixed back seat to move above the elastic fixed back seat, and then the lifting assembly mechanism controls the elastic fixed back seat to descend, so that the transparent face mask is installed on the elastic fixed back seat.

[0024] d. Complete assembly

[0025] After the transparent face mask is assembled, the lifting assembly mechanism is reset. Then, the lifting assembly mechanism drives the elastic fixed front seat to rotate, so that the elastic fixed front seat is set downward. The lifting assembly mechanism drives the elastic fixed front seat to descend again, so that the elastic fixed front seat and the elastic fixed rear seat clamp and fix the transparent face mask. Then, the fastening screws are screwed in to fix it, thus completing the manufacturing of the protective face mask.

[0026] Furthermore, the front of the elastically fixed rear seat is provided with a mounting cavity 1, within which a limiting seat 1 is provided, and a reinforcing rib 1 is provided between the limiting seat 1 and the mounting cavity 1. Connecting posts 1 are evenly distributed within the mounting cavity 1, and the top of each connecting post 1 protrudes upward to form a positioning part 1. Each connecting post 1 has a connecting screw hole. Correspondingly, the back of the elastically fixed front seat is provided with a mounting cavity 2, within which a limiting seat 2 is provided, and a reinforcing rib 2 is provided between the limiting seat 2 and the mounting cavity 2. Correspondingly, a connecting post 2 is provided in the mounting cavity 2, and the connecting post 2 has a stepped hole 2. Stepped hole two penetrates the elastically fixed front seat. The bottom of connecting column two protrudes downwards to form positioning part two. The top of the transparent face mask is correspondingly provided with an installation part. The installation part has stepped hole one corresponding to positioning part one and positioning part two. When the transparent face mask is fixed between the elastically fixed front seat and the elastically fixed rear seat, the installation part is clamped between limiting seat one and limiting seat two. Positioning part one is inserted into the bottom of stepped hole one, and positioning part two is inserted into the top of stepped hole one. The fastening screw passes through stepped hole two and stepped hole one and is tightened into the connecting screw hole. The setting of limiting seat one and limiting seat two limits the installation part of the transparent face mask. When the transparent face mask is installed in the elastically fixed front seat and the elastically fixed rear seat, limiting seat one supports the bottom of the installation part, and limiting seat two abuts against the top of the installation part, thereby improving the installation stability of the transparent face mask. The setting of positioning part one and positioning part two provides a quick positioning function for the installation of the transparent face mask and the elastically fixed front seat.

[0027] Furthermore, mounting cavity one has a notch one corresponding to the mounting part, and mounting cavity two has a notch two corresponding to the mounting part. When the transparent face shield is fixed between the elastic front seat and the elastic rear seat, the mounting part passes through notch one and notch two. The notch one and notch two facilitate the installation of the transparent face shield, while reducing the gap between the elastic front seat and the elastic rear seat, thus improving the aesthetics of the protective mask installation.

[0028] Furthermore, in step c, both ends of the back of the elastic fixed seat are provided with connecting posts three, and both ends of the elastic band are provided with through holes corresponding to the connecting posts three. When the elastic band is fixedly connected to the back of the elastic fixed seat, the connecting posts three pass through the through holes, and the ends of the connecting posts three are screwed into the limiting ends, which limit the elastic band. The cooperation between the connecting posts three and the limiting ends facilitates the quick installation of the elastic band.

[0029] Further, in step b, the flip-clamping assembly includes a clamping component and a flipping component. The clamping component clamps both ends of the elastic fixed rear seat, and the flipping component controls the clamping component to flip the elastic fixed rear seat. The clamping component includes a bracket and a clamping plate. Two brackets are correspondingly set on both sides of the assembly table. An adjusting screw is fixedly connected to the side of the clamping plate closest to the corresponding bracket. The adjusting screw passes through the corresponding bracket, and by driving the adjusting screw, the clamping plate is driven, so that the clamping plate is clamped on both sides of the elastic fixed rear seat. Adjusting nuts are screwed into both ends of the adjusting screw, and the adjusting nuts are tightened on both sides of the bracket. By loosening the adjusting nuts, the adjusting screw is controlled to drive the clamping plate to clamp on both sides of the elastic fixed rear seat. Then, the adjusting nuts are tightened to fix the elastic fixed rear seat and the bracket. Since the back of the elastic fixed rear seat is clamped facing upwards, it is convenient to install and fix the elastic band. After the elastic band is installed, the flipping component controls the bracket to flip, so that the back of the elastic fixed rear seat faces downwards, which is convenient for the installation of the transparent facial mask.

[0030] Furthermore, the flipping component includes a rotating base, a rotating shaft, a transmission gear, a rack, and a push cylinder. Two rotating bases are fixedly connected to both sides of the assembly table, and the rotating shaft is rotatably connected between the two rotating bases. The bracket is fixedly connected to the rotating shaft, and the transmission gear is fixedly connected to one end of the rotating shaft. The assembly table has a mounting groove on the side corresponding to the transmission gear, and a slide rail is connected in the mounting groove. The rack is slidably connected to the slide rail and meshes with the transmission gear. A connecting plate is fixedly connected to the front end of the rack. A cylinder mounting seat is fixedly connected to the side of the slide rail away from the bracket, and the push cylinder is fixedly connected to the cylinder mounting seat. A guide rod is provided at the output end of the push cylinder, and the guide rod is fixedly connected to the connecting plate. After the elastic band is installed, the push cylinder operates, controlling the guide rod to drive the connecting plate to push the rack, causing the rack to slide along the direction of the slide rail, thereby controlling the transmission gear to drive the rotating shaft to rotate, ultimately causing the bracket and the elastic fixed back seat to flip, so that the front of the elastic fixed back seat is facing upwards.

[0031] Furthermore, the lifting assembly mechanism includes an inverted T-shaped support, a lifting component, and an assembly component. The inverted T-shaped support is fixedly connected to the assembly table corresponding to the flip-clamping assembly. The lifting component is located on the side of the inverted T-shaped support near the flip-clamping assembly. The assembly component is connected to the lifting component, the transparent face mask is attached to the bottom of the assembly component, and the elastically fixed front seat is fixedly connected to the top of the assembly component. The lifting component controls the lifting and lowering of the assembly component. The elastically fixed front seat is fixed to the assembly component with its back facing upwards, the transparent face mask is attached to the bottom of the assembly component, and the lifting component controls the lifting and lowering of the assembly component.

[0032] Furthermore, the lifting component includes a lifting slide rail, a sliding base, a lead screw motor, and a ball screw. The lifting slide rail is fixedly connected to the side of the inverted T-shaped support near the flip-clamping assembly. Slider blocks are fixedly connected to both ends of the back of the sliding base, and these sliders are slidably connected to the lifting slide rail. A lead screw slider is located in the middle of the back of the sliding base. A motor mounting base is fixedly connected to the top of the inverted T-shaped support, and the lead screw motor is fixedly connected to the motor mounting base. The ball screw is connected to the output end of the lead screw motor, and the lead screw slider is connected to the ball screw. The lead screw motor controls the rotation of the ball screw, thereby controlling the lead screw slider to drive the sliding base to rise and fall along the ball screw. The lifting slide rail and slider provide a guiding function for the rising and falling of the sliding base.

[0033] Furthermore, the assembly includes a rotating base and an adsorption component. Adjustment frames are provided at both ends of the front side of the sliding base, each with an adjustment hole. Connecting screws are provided at both ends of the rotating base, passing through the adjustment holes. Connecting nuts are screwed into both ends of the connecting screws and tightened onto both sides of the adjustment frames. L-shaped limiting blocks one and two are provided at both ends of the top surface of the rotating base. L-shaped limiting block one abuts against the apex corner of one end of the elastically fixed front seat. Tightening bolts are screwed into both ends of the L-shaped limiting block, and tightening blocks are provided at the ends of the tightening bolts. The tightening bolts control the tightening blocks to be pressed against the outside of the elastically fixed front seat. An adsorption component is fixedly connected to the bottom of the rotating base, used to adsorb and fix the transparent facial cover. The flexible front seat is placed on the rotating seat with its back side facing up, so that the two clamping bolts of the flexible front seat abut against the L-shaped limiting block one. The two clamping bolts on the L-shaped limiting block two drive the clamping blocks to clamp against the other two apex corners of the flexible front seat, thereby fixing the flexible front seat to the top of the rotating seat. By loosening the connecting nut, the connecting screw is controlled to drive the rotating seat to rotate, thus realizing the rotation of the rotating seat. After the transparent face mask is installed, the rotating seat is controlled to drive the flexible front seat to rotate, so that the back side of the flexible front seat is set down.

[0034] Furthermore, the suction components include a fixed plate, a fixed block, a damping rod, a spring, a mounting plate, and a suction cup. The fixed plate is fixedly connected to the bottom of the rotating base via the fixed block. One end of the damping rod is fixedly connected to the fixed plate, and the other end is fixedly connected to the top surface of the mounting plate. The spring is sleeved on the outside of the damping rod, and the suction cup is fixedly connected to the bottom surface of the mounting plate. The suction cup is used to suction and fix the transparent facial mask. By suctioning the transparent facial mask, it is fixed to the bottom of the rotating base. The cooperation of the damping rod and the spring provides an elastic buffer for the installation of the transparent facial mask, preventing excessive downward pressure on the transparent facial mask when the lifting component controls its descent, which could cause damage.

[0035] The present invention, by adopting the above-described technical solution, has the following beneficial effects:

[0036] In the manufacturing method of this invention, an assembly table is used to assist in the manufacturing of the protective face mask. First, all the components required for the manufacturing of the protective face mask are prepared. Then, each component is clamped and fixed. The elastic fixing rear seat is clamped in the flip-clamping assembly of the assembly table with its back facing upwards. The elastic fixing front seat is fixed to the top of the lifting assembly mechanism. The transparent face mask is adsorbed on the bottom of the lifting assembly mechanism. The elastic fixing rear seat is clamped and fixed on its back to facilitate the installation of the elastic band. After the elastic band is installed, the flip-clamping assembly drives the elastic fixing rear seat to flip. Then, the lifting assembly mechanism installs the adsorbed transparent face mask on the elastic fixing rear seat. After the lifting assembly mechanism resets, it drives the elastic fixing front seat to rotate from the top to the bottom. The lifting mechanism then drives the elastic fixing front seat to descend again, fixing the transparent face mask between the elastic fixing front seat and the elastic fixing rear seat. Finally, the fastening screws are screwed in to fix it, completing the manufacturing of the protective face mask. This improves the manufacturing accuracy of the protective face mask, greatly increases the manufacturing efficiency of the face mask, and realizes the mass production of the protective face mask.

[0037] In this invention, the front of the elastically fixed rear seat is provided with a mounting cavity 1, a limiting seat 1 is provided inside the mounting cavity 1, a reinforcing rib 1 is provided between the limiting seat 1 and the mounting cavity 1, and connecting posts 1 are evenly distributed inside the mounting cavity 1. The top of the connecting posts 1 protrudes upward to form a positioning part 1, and the connecting posts 1 are provided with connecting screw holes. The back of the elastically fixed front seat is correspondingly provided with a mounting cavity 2, a limiting seat 2 is provided inside the mounting cavity 2, a reinforcing rib 2 is provided between the limiting seat 2 and the mounting cavity 2, and a connecting post 2 is correspondingly provided in the mounting cavity 2. The connecting post 2 is provided with stepped holes 2. Stepped hole two penetrates the elastically fixed front seat. The bottom of connecting column two protrudes downwards to form positioning part two. The top of the transparent face mask is correspondingly provided with an installation part. The installation part has stepped hole one corresponding to positioning part one and positioning part two. When the transparent face mask is fixed between the elastically fixed front seat and the elastically fixed rear seat, the installation part is clamped between limiting seat one and limiting seat two. Positioning part one is inserted into the bottom of stepped hole one, and positioning part two is inserted into the top of stepped hole one. The fastening screw passes through stepped hole two and stepped hole one and is tightened into the connecting screw hole. The setting of limiting seat one and limiting seat two limits the installation part of the transparent face mask. When the transparent face mask is installed in the elastically fixed front seat and the elastically fixed rear seat, limiting seat one supports the bottom of the installation part, and limiting seat two abuts against the top of the installation part, thereby improving the installation stability of the transparent face mask. The setting of positioning part one and positioning part two provides a quick positioning function for the installation of the transparent face mask and the elastically fixed front seat.

[0038] The flipping component of this invention includes a rotating base, a rotating shaft, a transmission gear, a rack, and a push cylinder. Two rotating bases are fixedly connected to both sides of an assembly table. The rotating shaft is rotatably connected between the two rotating bases. A bracket is fixedly connected to the rotating shaft. The transmission gear is fixedly connected to one end of the rotating shaft. The assembly table has a mounting groove on the side corresponding to the transmission gear, and a slide rail is connected in the mounting groove. The rack is slidably connected to the slide rail and meshes with the transmission gear. A connecting plate is fixedly connected to the front end of the rack. A cylinder mounting seat is fixedly connected to the side of the slide rail away from the bracket. The push cylinder is fixedly connected to the cylinder mounting seat. A guide rod is provided at the output end of the push cylinder, and the guide rod is fixedly connected to the connecting plate. After the elastic band is installed, the push cylinder operates, controlling the guide rod to drive the connecting plate to push the rack, causing the rack to slide along the direction of the slide rail. This controls the transmission gear to drive the rotating shaft to rotate, ultimately causing the bracket and the elastic fixed back seat to flip, so that the front of the elastic fixed back seat faces upward.

Detailed Implementation

[0055] like Figures 1 to 4 As shown, the safety protective face shield of the present invention includes: a transparent face shield 1, an elastic front seat 2 and an elastic rear seat 3. The top of the transparent face shield 1 is fixedly connected between the elastic front seat 2 and the elastic rear seat 3, and an elastic band 4 is fixedly connected to the rear side of the elastic rear seat 3.

[0056] The front of the elastically fixed rear seat 3 is provided with a mounting cavity 1 8, and a limiting seat 1 9 is provided inside the mounting cavity 1 8. A reinforcing rib 10 is provided between the limiting seat 1 9 and the mounting cavity 1 8. Connecting posts 11 are evenly distributed inside the mounting cavity 1 8. The top of the connecting posts 11 protrudes upward to form a positioning part 12. The connecting posts 11 are provided with connecting screw holes 13. The back of the elastically fixed front seat 2 is provided with a mounting cavity 2 14. A limiting seat 2 15 is provided inside the mounting cavity 2 14. A reinforcing rib 2 16 is provided between the limiting seat 2 15 and the mounting cavity 2 14. A connecting post 2 17 is provided in the mounting cavity 2 14. The connecting post 2 17 is provided with a stepped hole 2 18. The second 18 penetrates the elastically fixed front seat 2, and the bottom of the second connecting column 17 protrudes downward to form a positioning part 19. The top of the transparent face cover 1 is provided with a mounting part 20. The mounting part 20 is provided with a stepped hole 21 corresponding to the positioning part 12 and the positioning part 29. When the transparent face cover 1 is fixed between the elastically fixed front seat 2 and the elastically fixed rear seat 3, the mounting part 20 is locked between the limiting seat 19 and the limiting seat 25. The positioning part 12 is inserted into the bottom of the stepped hole 21, and the positioning part 29 is inserted into the top of the stepped hole 21. The fastening screw 22 passes through the stepped hole 28 and the stepped hole 21 and is tightened in the connecting screw hole 13. The setting of limiting seat 1 9 and limiting seat 2 15 limits the mounting part 20 of the transparent face mask 1. When the transparent face mask 1 is installed in the elastic fixed front seat 2 and the elastic fixed rear seat 3, the limiting seat 1 9 is supported at the bottom of the mounting part 20 and the limiting seat 2 15 is against the top of the mounting part 20, thereby improving the installation stability of the transparent face mask 1. The setting of positioning part 1 12 and positioning part 2 19 plays a role in quickly positioning the transparent face mask 1 and the elastic fixed front seat 2.

[0057] Mounting cavity 18 has a notch 23 corresponding to mounting part 20, and mounting cavity 24 has a notch 24 corresponding to mounting part 20. When the transparent face shield 1 is fixed between the elastic front seat 2 and the elastic rear seat 3, the mounting part 20 passes through notch 23 and notch 24. The notch 23 and notch 24 facilitate the installation of the transparent face shield 1, while reducing the gap between the elastic front seat 2 and the elastic rear seat 3, thus improving the aesthetics of the protective mask installation.

[0058] Both ends of the back of the elastic fixed rear seat 3 are provided with connecting posts 25. The two ends of the elastic band 4 are provided with through holes 26 corresponding to the connecting posts 25. When the elastic band 4 is fixedly connected to the back of the elastic fixed rear seat 3, the connecting posts 25 pass through the through holes 26, and the ends of the connecting posts 25 are screwed into the limiting ends 27, which limit the elastic band 4. The cooperation between the connecting posts 25 and the limiting ends 27 facilitates the quick installation of the elastic band 4.

[0059] like Figures 5 to 14 The diagram shows a method for manufacturing the safety protective face shield of the present invention, which includes the following steps:

[0060] a. Preparations before production

[0061] First, prepare all the necessary components for manufacturing the protective mask, and then clean and reset the assembly table 5 required for mask manufacturing.

[0062] b. Clamping

[0063] 1) Clamping of the elastically fixed rear seat

[0064] First, place the elastic fixing back seat 3 with its back side facing up on the assembly table 5. Then, the flip-clamping assembly 6 on the assembly table 5 clamps and fixes the elastic fixing back seat 3, so that the elastic fixing back seat 3 is fixed on the assembly table 5.

[0065] 2) Clamping of the flexible fixed front seat

[0066] A lifting assembly mechanism 7 is set on one side of the assembly table 5, corresponding to the flip clamping assembly 6. The back of the elastic fixed front seat 2 is placed on top of the lifting assembly mechanism 7 with the corresponding elastic fixed rear seat 3 facing upward. The lifting assembly mechanism 7 fixes the elastic fixed front seat 2.

[0067] 3) Fixation of the transparent facial mask

[0068] Place the transparent face mask 1 face up at the bottom of the lifting assembly mechanism 7. The lifting assembly mechanism 7 will attach the transparent face mask 1 to the bottom of the lifting assembly mechanism.

[0069] c. Assembly

[0070] 1) Elastic band assembly

[0071] The operator fixes the elastic band 4 to the back of the elastic fixing seat 3, and then flips the clamping assembly 6 to control the elastic fixing seat 3 with the elastic band 4 to flip so that the front of the elastic fixing seat 3 is facing upward.

[0072] 2) Assembly of the transparent facial mask

[0073] The lifting assembly mechanism 7 controls the elastic fixed back seat 3 to move above the elastic fixed back seat 3, and then the lifting assembly mechanism 7 controls the elastic fixed back seat 3 to descend, so that the transparent face mask 1 is installed on the elastic fixed back seat 3.

[0074] d. Complete assembly

[0075] After the transparent face mask 1 is assembled, the lifting assembly mechanism 7 is reset. Then, the lifting assembly mechanism 7 drives the elastic fixed front seat 2 to rotate, so that the elastic fixed front seat 2 is set downward. The lifting assembly mechanism 7 drives the elastic fixed front seat 2 to descend again, so that the elastic fixed front seat 2 and the elastic fixed rear seat 3 clamp and fix the transparent face mask 1. Then, the fastening screw 22 is screwed in to fix it, thus completing the manufacturing of the protective face mask.

[0076] In step b, the flipping clamping assembly 6 includes a clamping member 28 and a flipping member 29. The clamping member 28 clamps the two ends of the elastic fixed back seat 3, and the flipping member 29 controls the clamping member 28 to drive the elastic fixed back seat 3 to flip. The clamping member 28 includes a bracket 30 and a clamping plate 31. The two brackets 30 are respectively set on both sides of the assembly table 5. An adjusting screw 32 is fixedly connected to the side of the clamping plate 31 near the corresponding bracket 30. The adjusting screw 32 passes through the corresponding bracket 30. By driving the adjusting screw 32, the clamping plate 31 is driven, so that the clamping plate 31 is clamped on both sides of the elastic fixed back seat 3. Adjusting nuts 33 are screwed into both ends of the adjusting screw 32. The adjusting nuts 33 are tightened on both sides of the bracket 30. By loosening the adjusting nut 33, the adjusting screw 32 is controlled to drive the clamping plate 31 to clamp on both sides of the elastic fixed back seat 3. Then, the adjusting nut 33 is fixed so that the elastic fixed back seat 3 is fixed to the bracket 30. Since the back of the elastic fixed back seat 3 is clamped facing upwards, it is convenient to install and fix the elastic band 4. After the elastic band 4 is installed, the bracket 30 is flipped by the flipping part 29 so that the back of the elastic fixed back seat 3 faces downwards, which is convenient for the installation of the transparent face mask 1.
