Description

Technical Field

[0001] The invention belongs to the technical field of energy-saving buildings, in particular to a telescopic camping house. Background Art

[0002] The camping house in the prior art is composed of a plurality of modules or units, which can be flexibly spliced ​​and adjusted in layout according to actual use requirements. The camping house has different types according to its functions, for example, a camping house for accommodation, a camping house for office, etc.;

[0003] Camping houses are mostly used as temporary housing. Some camping houses need to be able to see the outside. For example, temporary housing in some scenic spots needs to have large windows to see the outside scenery. For example, when holding large-scale outdoor music festivals, concerts and other performances, temporary operation rooms set up around the stage or near the audience area need to have large windows. Sound, lighting and other technical personnel can observe the performance positions and movements of the actors on the stage through the windows, so as to accurately adjust the sound effects and lighting effects to create the best performance atmosphere.

[0004] It can be seen that the use of camping houses as temporary housing also has a high demand for large-sized windows, but installing large-sized windows on camping houses will make the overall size of the camping houses larger, making transportation more difficult and the transportation cost higher;

[0005] In order to reduce transportation costs, the prior art uses a telescopic camping house for transportation, and after being transported to the installation location, it is unfolded. However, the existing telescopic camping house is mostly telescopic forward and backward, and the size of the window does not change after the extension, and thus it is difficult to adapt to some scenes with special requirements for the window size;

[0006] Although the sliding window technology in the prior art can be combined with the existing telescopic camping house, so that the windows of the camping house move synchronously and increase or decrease synchronously when the camping house is extended and retracted; however, in the prior art, the sliding window has a sealing function only when it is fully extended, which is equivalent to the sliding window closed state. When it is not fully extended, it is equivalent to the sliding window open state, and there is no sealing requirement between the two windows. Therefore, when it is not fully extended, the sliding window does not have a sealing function, and the heat inside it is easy to dissipate from the gap between the two windows, affecting the energy-saving performance of the building;

[0007] Due to the size of the installation site, some sites are small and the retractable camping house cannot be fully unfolded, which results in the sliding window not being able to be fully unfolded for sealing when the above method is adopted. The intersection between the two windows is easily in an unsealed state, which results in the sliding window technology in the prior art still having room for improvement when combined with the existing retractable camping house.

DETAILED DESCRIPTION

[0035] The following will be combined with the drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the present invention.

[0036] Embodiment 1:

[0037] A telescopic camping house, as shown in the accompanying drawings of the specification Figure 1-Figure 9 As shown, it includes a first room body 1 and a second room body 2, the second room body 2 is inserted inside the first room body 1, and the second room body 2 is slidably connected to the first room body 1 through a slide rail device, a door 3 is installed on the first room body 1, and observation windows 4 are fixedly installed on the first room body 1 and the second room body 2, a sealing component is arranged between the two observation windows 4, and the sealing component is used to seal the intersection 5 between the two observation windows 4, the sealing component of the observation window 4 located on the outside is arranged at the right end, and the sealing component of the observation window 4 located on the inside is arranged at the left end;

[0038] The sealing assembly includes a mounting groove 6, which is provided on the window frame of the observation window 4. A push bar 7 is slidably inserted in the mounting groove 6. Mounting plates 8 are fixed to the upper and lower ends of the push bar 7. A cylindrical sealing strip is provided between the two mounting plates 8. A pushing device 9 is fixed between the pushing bar 7 and the mounting groove 6. The pushing device can be an electric push rod.

[0039] The sealing strip includes a rotating rod 11 and an airbag 12 . The rotating rod 11 is rotatably connected to the mounting plate 8 , and the airbag 12 is sleeved and fixed on the surface of the rotating rod 11 .

[0040] Specific work flow: Camping houses are mostly used as temporary housing. Some camping houses need to be able to see the outside. For example, temporary housing in some scenic spots needs to have large windows to see the outside scenery. For example, when holding large-scale outdoor music festivals, concerts and other performances, temporary operation rooms set up around the stage or near the audience area need to have large windows. Sound, lighting and other technical personnel can observe the performance positions and movements of the actors on the stage through the windows, so as to accurately adjust the sound effects and lighting effects to create the best performance atmosphere.

[0041] It can be seen that the use of camping houses as temporary housing also has a high demand for large-sized windows, but installing large-sized windows on camping houses will make the overall size of the camping houses larger, making transportation more difficult and the transportation cost higher;

[0042] In order to reduce transportation costs, the prior art uses a telescopic camping house for transportation, and after being transported to the installation location, it is unfolded. However, the existing telescopic camping house is mostly telescopic forward and backward, and the size of the window does not change after the extension, and thus it is difficult to adapt to some scenes with special requirements for the window size;

[0043] Although the sliding window technology in the prior art can be combined with the existing telescopic camping house, so that the windows of the camping house move synchronously and increase or decrease synchronously when the camping house is extended and retracted; however, in the prior art, the sliding window has a sealing function only when it is fully extended, which is equivalent to the sliding window closed state. When it is not fully extended, it is equivalent to the sliding window open state, and there is no sealing requirement between the two windows. Therefore, when it is not fully extended, the sliding window does not have a sealing function; however, affected by the size of the installation site, some sites are small, and the telescopic camping house cannot be fully extended, which leads to the above-mentioned method. The sliding window cannot be fully extended for sealing, and the intersection position 5 between the two windows is easily in an unsealed state, which leads to the sliding window technology in the prior art still has room for improvement when combined with the existing telescopic camping house. The specific improvement ideas are as follows:

[0044] When installing the camping house, first fix the first house body 1 on the ground, then pull the second house body 2 to move, and unfold the camping house as a whole. The observation window 4 on the second house body 2 moves with the second house body 2, so that the observation window 4 as a whole is also synchronously enlarged, thereby increasing the viewing area;

[0045] When the installation site is small, the two observation windows 4 are difficult to fully unfold, and there is a gap 13 between them. In winter, the indoor heat will be continuously transferred to the outside through these gaps, resulting in a large amount of indoor heat loss. In order to maintain a comfortable indoor temperature, more energy needs to be consumed. For example, heating equipment such as heating needs to be continuously operated at a high intensity to replenish the lost heat, which is not conducive to the overall energy saving of the building.

[0046] In this embodiment, a sealing assembly is arranged between the two observation windows 4. When the observation window 4 is moved and unfolded, one end of the airbag 12 is pushed to the outside of the mounting groove 6 by the push bar 7, so that the airbag 12 contacts the glass surface of the observation window 4. As the observation window 4 moves, the airbag 12 in the sealing assembly rotates on the glass surface of the observation window 4. In the moving state, the airbag 12 is arranged to always contact the glass surface, so that both sides of the intersection 5 between the two observation windows 4 are shielded, thereby helping to reduce the chance of dust entering.

[0047] In addition, the airbag 12 can be actively inflated later to expand the airbag 12, thereby increasing the sealing performance of the airbag 12 and sealing the intersection 5 between the two observation windows 4, thereby reducing the possibility of heat loss from this position and ensuring the energy saving of the entire building;

[0048] In addition, the window material of the observation window 4 can be made of heat-insulating material, for example, a low-emissivity coating is applied on the glass surface. This film has a high transmittance to visible light, which allows the room to obtain sufficient natural lighting. At the same time, it has a low emissivity and a high reflectivity to long-wave thermal radiation such as infrared rays. In winter, it can reflect the thermal radiation emitted by indoor objects back into the room, reduce the heat loss to the outside through the glass, and play a role in heat preservation; in summer, it can block the outdoor heat radiation from entering the room, reducing the air conditioning refrigeration load; or a broken bridge aluminum window frame is used, that is, a heat insulation strip is added in the middle of the aluminum alloy profile, and the aluminum alloy profile is disconnected from the middle to form a broken bridge, so as to prevent the conduction of heat through the window frame;

[0049] On the other hand, compared with the traditional sealing strip, the traditional sealing strip adopts a sliding contact mode. During the movement process, if there are dust and debris between the sealing strip and the glass, the sealing strip may drive the dust and debris to move, causing scratches on the glass and affecting the viewing effect; while this embodiment adopts rolling contact, which can avoid driving the dust and debris to move, thereby helping to reduce the scratches on the glass surface;

[0050] It should be noted that sealing belts are fixed on the upper and lower ends of the observation window 4 surface located at the airbag 12, so as to seal the upper and lower ends of the intersection 5 of the two observation windows 4, and during the movement, since the sealing belt does not contact the glass and slide and rub, it will not scratch the glass, and no special design is required.

[0051] Embodiment 2:

[0052] On the basis of the first embodiment, an inflatable device is fixed on the push bar 7, and the inflatable device is used to inflate the inside of the airbag 12. The airbag 12 has at least a first air pressure state and a second air pressure state. The air pressure value of the second air pressure state is greater than the air pressure value of the first air pressure state. When the airbag 12 is in the first air pressure state, there is a gap 13 between the outer wall of the airbag 12 and the mounting groove 6 and the mounting plate 8. When the airbag 12 is in the second air pressure state, the airbag 12 is tightly attached to the mounting groove 6 and the mounting plate 8.

[0053] Furthermore, the inflation device includes an air pump 14, which is fixed on the push bar 7. The push bar 7, the mounting plate 8, and the rotating rod 11 are provided with a delivery channel 15, and the air pump 14 is connected to the inside of the airbag 12 through the delivery channel 15;

[0054] Furthermore, an annular plate 16 is fixed to both upper and lower ends of the airbag 12, and a toothed plate 17 is fixed to one end of the mounting plate 8 close to the airbag 12. A plurality of positioning teeth 18 are fixed to the surface of the annular plate 16. When the pressure is in the second air pressure state, the positioning teeth 18 are inserted into the tooth grooves of the toothed plate 17.

[0055] As can be seen from the first embodiment, in order to prevent dust from entering the intersection 5 between the two observation windows 4 when the observation windows 4 are unfolded, the airbag 12 needs to be in contact with the glass surface all the time, and in order to prevent the glass from being scratched during the contact process, the airbag 12 needs to be in a rolling state;

[0056] If the airbag 12 is in the second air pressure state in the initial state, the surface of the airbag 12 is in close contact with the mounting groove 6 and the mounting plate 8. Under the action of friction, it will be difficult for the airbag 12 to rotate. In addition, during the process of the two observation windows 4 moving away from each other, the intersection 5 between them gradually shrinks, so that the gas inside the intersection 5 is squeezed outward. If the airbag 12 completely seals both sides of the observation window 4, it will be difficult for the gas inside the intersection 5 to be discharged, making it difficult for the observation window 4 to move and unfold.

[0057] In view of this, in this embodiment, in the initial state, the airbag 12 is in the first air pressure state, and there is a gap 13 between the outer wall of the airbag 12 and the mounting groove 6 and the mounting plate 8, so that the gas inside the intersection position 5 is conveniently discharged outward from the gap 13; and in the process of the two observation windows 4 moving away from each other, there is always an airflow discharged outward at the gap 13, and under the blowing action of the discharged airflow, it can also prevent external dust from entering from the gap 13 and contaminating the glass at the intersection position 5;

[0058] When the position of the observation window 4 is adjusted and does not need to be moved, the air pump 14 is started to inflate the air inside the airbag 12 through the delivery channel 15, so that the airbag 12 expands to the second air pressure state, and the outer wall thereof is in close contact with the mounting groove 6 and the mounting plate 8, and the gap 13 is filled and sealed, thereby restoring the sealing performance of the airbag 12 and reducing the heat overflow from the gap 13, which is beneficial to ensuring the energy saving of the position of the observation window 4;

[0059] It should be noted that an air pressure sensor may be provided inside the airbag 12 to detect the air pressure inside the airbag 12, thereby determining whether it is in the first air pressure state or the second air pressure state;

[0060] Furthermore, the normal ideal sealing state requires that the sealing strip and the glass surface are tightly, continuously and stably attached to form a complete sealing defense line to prevent the passage of gas, liquid, etc. If the camping house is used in a scene prone to vibration such as a construction site, for example, the vibration caused by the construction of large construction equipment may cause relative movement between the observation windows 4. If the rotating rod 11 of the airbag 12 is in an unlocked state, it may cause the airbag 12 to rotate in the opposite direction. During the rotation process, it is very likely that the airbag 12 will be partially out of contact with the glass surface, thereby destroying the continuity of the seal and greatly reducing the sealing effect. For example, air, water vapor, etc. are easy to leak from the tiny gaps 13 caused by these disengagements;

[0061] In this embodiment, an annular plate 16 is arranged at the bottom of the airbag 12. When the position of the observation window 4 is adjusted and the gap 13 of the airbag 12 needs to be sealed, the airbag 12 is expanded by inflating the inside of the airbag 12. The upper and lower ends of the airbag 12 push the corresponding annular plate 16 toward the side close to the tooth groove plate 17, so that the positioning teeth 18 on the annular plate 16 are inserted into the tooth groove of the tooth groove plate 17. The positioning teeth 18 are limited by the tooth groove of the tooth groove plate 17, thereby limiting the rotation of the rotating rod 11 and the airbag 12, thereby ensuring that the airbag 12 can be continuously and stably attached between the glass of the two observation windows 4, ensuring the sealing of this position, and further ensuring the energy saving of the position of the observation window 4;

[0062] It should be noted that the top of the positioning tooth 18 is triangular. When the positioning tooth 18 is not accurately inserted into the corresponding tooth groove, under the guidance of the triangular inclined surface and because the airbag 12 is in a flexible state, the positioning tooth 18 can drive the annular plate 16 to slightly shift to make way, thereby accurately inserting into the tooth groove.

[0063] Embodiment three:

[0064] On the basis of the second embodiment, a curved surface 19 is provided on the side of the push bar 7 close to the airbag 12, and a groove 21 is provided on the curved surface 19. A vertical roller 22 is rotatably connected in the groove 21, and the surface of the roller 22 is in contact with the airbag 12. A plurality of annular grooves 23 are provided on the surface of the roller 22.

[0065] Furthermore, a first mesh plate 24 is fixedly connected in each of the annular grooves 23 . The first mesh plate 24 is annular and has a plurality of mesh holes distributed on its surface.

[0066] Furthermore, there are two rollers 22 , which are symmetrically arranged at two ends of the arc surface 19 , and the annular grooves 23 on the two rollers 22 are staggered.

[0067] Specific working process: The material of the airbag 12 is usually some high molecular polymers, etc. During the rotation process, the surface of the airbag 12 rubs against the objects in the surrounding environment, and this friction will generate static electricity on the surface of the airbag 12. Static electricity has the characteristic of adsorbing light and small objects, and dust particles are usually small and light, so dust is easy to gather on the surface of the airbag 12; the following implementation method can solve the above problem, and the specific working method is as follows:

[0068] As can be seen from the above-mentioned second embodiment, when the camping house is installed so that the two observation windows 4 are away from each other, the gas will flow out from the gap 13 between the outer wall of the airbag 12 and the installation groove 6, and blow the surface of the airbag 12, thereby blowing the dust adhered to the surface of the airbag 12 outward, and preventing the dust on the surface of the airbag 12 from being driven into the inside of the intersection position 5;

[0069] In this embodiment, a curved surface 19 is provided on one side of the push bar 7. The shape of the curved surface 19 is more consistent with the natural streamlined trajectory of the airflow, so that the airflow can flow along the curved surface 19 more smoothly without causing severe disturbances due to sudden corners or sharp edges. The smoothness of the airflow is improved by providing the curved surface 19. When the airflow passes smoothly, a relatively stable airflow field with a certain strength can be formed. This stable and powerful airflow can more effectively impact the dust attached to the surface of the airbag 12, so that the dust is more easily lifted from the surface of the airbag 12 and other positions and enters the airflow for discharge;

[0070] Furthermore, by arranging a roller 22 on one side of the airbag 12, the surface of the airbag 12 is squeezed, so that the surface of the airbag 12 is deformed, and this deformation will destroy the relatively stable contact state between the dust and the surface of the airbag 12, so that the adhesion force on the dust will change. For example, the convexity or concaveness on the surface will make the force on the dust in the local position no longer uniform, and the force balance that originally allowed the dust to adhere stably will be broken, so that it is easier to detach from the surface of the airbag 12;

[0071] Moreover, when the two observation windows 4 are away from each other, the airbag 12 rotates, so that the roller 22 in contact with the airbag 12 rotates, and the roller 22 is in a rolling state, which can reduce the friction between the roller 22 and the airbag 12, thereby reducing the wear of the airbag 12 during the extrusion process;

[0072] Furthermore, an annular groove 23 is provided on the surface of the drum 22, and airflow can pass through the annular groove 23, which is conducive to timely blowing away the dust detached due to the deformation of the airbag 12, thereby improving the cleaning efficiency;

[0073] The surface of the airbag 12 of some materials is relatively soft. When squeezed, it may sink into the annular groove 23, resulting in blockage of the annular groove 23 and affecting the airflow. In this embodiment, the airbag 12 is blocked by installing a first mesh plate 24 in the annular groove 23, which not only prevents the airbag 12 from sinking into the annular groove 23, but also allows dust to enter the annular groove 23 through the mesh and flow out with the airflow, thereby ensuring the cleaning function;

[0074] Protrusions may be fixed on the surface of the first mesh plate 24 to increase the roughness of the surface, thereby increasing the deformation degree of the airbag 12 and further facilitating the separation of dust on the surface;

[0075] Furthermore, when the airbag 12 is squeezed, the area between two adjacent annular grooves 23 has no airflow passing through, resulting in poor dust discharge effect. By arranging two rollers 22, the annular grooves 23 are arranged alternately, which can ensure that all positions on the surface of the airbag 12 can contact the annular grooves 23, so that the airbag 12 is squeezed, and after the dust is separated, it can immediately enter the annular grooves 23 and contact the airflow, thereby ensuring the dust discharge effect;

[0076] On the other hand, when the airbag 12 expands to the second air pressure state and seals the gap 13, rollers 22 are provided at both ends of the arc surface 19 to squeeze the airbag 12 from both ends, so that the airbag 12 and the gap 13 at both ends of the arc surface 19 fit more closely, thereby ensuring the sealing performance of the airbag 12.

[0077] Embodiment 4:

[0078] On the basis of the third embodiment, there is an installation space 25 between the top of the first mesh plate 24 and the inner wall of the annular groove 23, the second mesh plate 26 is rotatably connected to the inner ring surface of the first mesh plate 24, a slide groove 27 is provided on the inner ring surface of the first mesh plate 24, a slider 28 is slidably connected in the slide groove 27, and the slider 28 is fixed on the outer ring surface of the second mesh plate 26;

[0079] A friction ring 29 is fixed in the installation space 25. When the drum 22 rotates forward, the mesh holes of the second mesh plate 26 are connected with the mesh holes of the first mesh plate 24. When the drum 22 rotates reversely, the mesh holes of the second mesh plate 26 and the mesh holes of the first mesh plate 24 are staggered and closed.

[0080] Taking the left roller 22 as an example, when the two observation windows 3 are close to each other, the rotation direction of the roller 22 is forward, and when the two observation windows 3 are away from each other, the rotation direction of the roller 22 is reverse;

[0081] It should be noted that, according to the third embodiment, during the rotation of the airbag 12, friction occurs between the side wall and the glass, which may generate static electricity. However, since the two ends of the airbag 12 do not rub against the object, the static electricity generated there is smaller than that of the side wall, and thus the dust adsorbed by the side wall of the airbag 12 is generally more than that of the upper and lower ends.

[0082] Secondly, when installing the camping house, a retraction operation may be performed, causing the two observation windows 4 to be close to each other. For example, when the installer pulls the second house body 2 to move, the pulling distance is misjudged and it is found that the pulling distance is too long, so it is necessary to retract a part of the distance; during the retraction process, the two observation windows 4 are close to each other, and the space at the intersection position 5 becomes larger, which will absorb external air from the installation space 25 area inward. At this time, if there is gas passing through the side wall position of the airbag 12, the dust on the side wall of the airbag 12 will be absorbed inward, causing the intersection position 5 between the two observation windows 4 to be contaminated;

[0083] This embodiment can solve the above problems. The specific working method is as follows: when the two observation windows 4 move away from each other, the airbag 12 rotates in the opposite direction, and the roller 22 in contact with the airbag 12 rotates forward. In the initial stage of the rotation of the roller 22, the first mesh plate 24 and the friction ring 29 are driven to move by the roller 22. The surface of the friction ring 29 is provided with a rubber material with a high friction coefficient, and the surface of the rubber material is slightly protruding from the surface of the first mesh plate 24. During the rotation process, the friction force when the friction ring 29 contacts the inner wall of the groove 21 is relatively large. Under the action of friction, the friction ring 29 The difficulty of movement is greater than that of the first mesh plate 24, so that in the initial stage of the rotation of the drum 22, the first mesh plate 24 moves first, and the friction ring 29 and the second mesh plate 26 move later, so that the slide groove 27 on the first mesh plate 24 moves outside the slider 28 until one end of the slide groove 27 contacts the slider 28, and then the slider 28 is pushed to move by the end of the slide groove 27, thereby driving the second mesh plate 26 and the first mesh plate 24 to move synchronously. At this time, the mesh holes of the second mesh plate 26 are connected with the mesh holes of the first mesh plate 24, so that dust can pass through the mesh holes and enter the inside of the annular groove 23;

[0084] When the two observation windows 4 are close to each other, the airbag 12 rotates forward, and the roller 22 rotates reversely, and the rotation direction of the roller 22 changes. At this time, under the damping effect of the friction ring 29, the first mesh plate 24 moves first, and one end of the slide groove 27 gradually separates from the slider 28, and the mesh of the second mesh plate 26 gradually separates from the mesh of the first mesh plate 24.

[0085] As the first mesh plate 24 continues to move, the other end of the slide groove 27 contacts the slider 28, and the other end of the slide groove 27 pushes the slider 28 to move, thereby driving the second mesh plate 26 and the first mesh plate 24 to move synchronously. At this time, the mesh holes of the second mesh plate 26 and the mesh holes of the first mesh plate 24 are staggered and closed;

[0086] During the retraction process, the mesh holes on the first mesh plate 24 are closed to block the annular groove 23, thereby ensuring that the airflow is not sucked in from the side of the airbag 12, thereby preventing the dust stuck on the side of the airbag 12 from being directly sucked into the intersection 5 between the two observation windows 4 during the airflow suction process;

[0087] At this time, the airflow can only be sucked in from the upper and lower ends of the airbag 12, and the upper and lower end surfaces of the airbag 12 generate little static electricity and will not stick to a large amount of dust, which is beneficial to reduce the pollution caused to the intersection position 5 between the two observation windows 4.

[0088] Embodiment five:

[0089] On the basis of the second embodiment, an arc-shaped sealing plate 31 is arranged inside the annular groove 23, sealing sheets 32 are fixed at both ends of the sealing plate 31, a positioning block 33 is fixed in the middle of the sealing plate 31, the positioning block 33 is made of ferromagnetic material, and a magnet 34 is fixed on the inner wall of the groove 21.

[0090] Furthermore, there are two positioning blocks 33 , and a roller 35 is disposed between the two positioning blocks 33 . The roller 35 is rotatably connected to the two positioning blocks 33 via a rotating shaft 36 .

[0091] Furthermore, the positioning blocks 33 are each provided with a sliding groove 37 , and a sliding block 38 is slidably connected inside the sliding groove 37 . The two sliding blocks 38 are respectively fixed to the upper and lower ends of the rotating shaft 36 , and a spring 39 is fixed between the sliding block 38 and the inner wall of the sliding groove 37 .

[0092] Specific working process: in the process of the two observation windows 4 moving away from each other, that is, in the process of the airflow blowing outward from the gap 13, due to the annular shape of the annular groove 23, part of the airflow will not contact the airbag 12, and will directly flow out from the side of the annular groove 23 away from the airbag 12, resulting in part of the airflow being lost and wasted. The present invention provides a sealing plate 31 in the annular groove 23, and the sealing sheets 32 at both ends of the sealing plate 31 are in contact with the second mesh plate 26 to block the space in the annular groove 23, thereby preventing the airflow from flowing to the side of the annular groove 23 away from the airbag 12, thereby reducing the loss and waste of the airflow, so that the airflow can impact the dust on the side of the airbag 12 with a stronger force, making it easier to be lifted from the attached surface, and can more efficiently blow out the lifted dust continuously, avoiding the dust from settling again due to the weakening of the airflow during the cleaning process, thereby comprehensively improving the efficiency of dust cleaning;

[0093] Furthermore, since the roller 22 is always in a rotating state, and the sealing plate 31 is placed inside the annular groove 23 and is not connected to the internal structure of the annular groove 23, in order to maintain the stable state of the sealing plate 31, in this embodiment, a positioning block 33 is installed on the sealing plate 31. The positioning block 33 can be made of magnetic materials such as iron. A magnet 34 is arranged inside the groove 21. The positioning block 33 is adsorbed by the adsorption effect of the magnet 34, thereby limiting the movement of the positioning block 33 with the roller 22, thereby ensuring the stability of the sealing plate 31 and the sealing sheet 32.

[0094] In order to reduce the adverse effect of the friction between the positioning block 23 and the second mesh plate 26 on the magnetic attraction, in this embodiment, a roller 35 is installed between the positioning block 33 and the second mesh plate 26 to avoid direct contact between the positioning block 33 and the second mesh plate 26. When the second mesh plate 26 moves, the roller 35 can rotate to make way, thereby reducing the possibility that the second mesh plate 26 drives the sealing plate 31 to move under the action of friction.

[0095] In order to further reduce the influence of friction, by designing the contact surface between the two sealing sheets 32 and the second mesh plate 26 to be smaller, the instability of the sealing plate 31 caused by friction can also be reduced.

[0096] Furthermore, the sealing sheet 32 ​​can be made of a flexible material. During the movement of the second mesh plate 26, the flexible sealing sheet 32 ​​can be deformed to give way, thereby facilitating the blocking performance of the sealing sheet 32.

[0097] Furthermore, by providing a sliding groove 37 on the positioning block 33, when dust or debris accumulates on the second mesh plate 26, when the accumulation contacts the roller 35, the roller 35 can push the rotating shaft 36 and the sliding block 38 to slide into the sliding groove 37 to make way, thereby preventing the second mesh plate 26 from getting stuck, causing the drum 22 to stop rotating as a whole, and causing wear to the airbag 12.
