Description

Technical Field

[0001] This invention belongs to the field of cabin building technology, specifically a device for unfolding and retracting mosquito netting for cabin buildings. Background Technology

[0002] In outdoor recreational, tourism, or residential environments, especially in summer, mosquitoes and other flying insects are a major nuisance. These small creatures not only cause itching and discomfort but can also spread diseases, posing a threat to health. This problem is particularly prominent in cabin-like buildings (such as campervans, mobile homes, and temporary shelters) because these spaces often require frequent opening of doors and windows to maintain ventilation, while also needing to prevent mosquitoes from entering. This necessitates the use of mosquito nets.

[0003] CN108374629A discloses a pole with a wound-wound mesh and a concealed integrated protective mesh, relating to the field of doors and windows. The pole with the wound-wound mesh disclosed in this invention has a fixed shaft and a roller sleeved around the fixed shaft and rotatable relative to it, with the roller connected to the fixed shaft by a torsion spring. The fixed end of the mesh is fixed and wound around the roller, while the free end of the mesh passes through a through hole outside the housing. A buckle is provided at the free end of the mesh, and a slot is provided on the housing to engage with the buckle. This pole can be assembled into a protective mesh, which can be installed on a window frame to form a protective window. Operating the window sash causes the protective mesh to unfold or fold. Through the engagement of the buckle and the slot, when the protective mesh is folded, the torsion spring drives the roller to rotate, winding the mesh, which is then stored and concealed within the housing. The operation is simple and convenient, and improves aesthetics. When the protective mesh is unfolded, it unfolds with the movement of the pole, providing protection against theft and insects.

[0004] The above-mentioned device requires the user to open the window first and then pull the buckle to engage with the slot in order to unfold the mosquito net. During this process, mosquitoes and other flying insects can easily enter the cabin through the window, which fails to achieve the effect of strictly preventing mosquito intrusion. Therefore, a mosquito net unfolding and retracting device for cabin buildings is proposed. Summary of the Invention

[0017] Compared with the prior art, the beneficial effects of the present invention are as follows:

[0018] This invention facilitates the unfolding and retraction of the net cover by setting up a first gear and a second rack, etc. The upward movement of the lifting window drives the sliding plate to move synchronously upward with the lifting window inside the first sliding groove. The sliding plate pulls the extended net cover and support strip out of the retraction groove and tightens them. At this time, the support strip will fit against the surface of the cabin shell, so that the taut net cover blocks the gap between the lifting window and the window edge. The net cover and the lifting window move synchronously, so that the user only needs to operate once to complete the dual tasks of opening the window and preventing mosquitoes and insects. This simplifies the operation process, improves the user experience, and is easy to operate. At the same time, it solves the problem of mosquitoes and other flying insects entering the cabin through the window when opening the window first and then unfolding the net cover, preventing mosquitoes and insects from entering the cabin during the window opening process.

[0019] This invention, through the combination of piston and baffle structures, facilitates cleaning of the mesh cover when it is retracted. When the pull-up window is closed, the first groove opens, allowing gas inside the air storage tank to escape from the first groove. This airflow blows air onto the mesh cover at the bottom of the sliding plate, which is about to be retracted into the storage slot. The airflow blows away mosquitoes and dust attached to the mesh cover, thus performing self-cleaning. This prevents mosquitoes and dust from entering the device and causing damage or contamination, extending the service life of the mesh cover, reducing replacement frequency and costs, and alleviating the burden of regular manual cleaning. The frequency and complexity of maintenance are reduced, saving time and effort. Attached Figure Description

[0030] The technical solutions of the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of the present invention.

[0031] like Figures 1 to 9 As shown, the present invention provides a device for unfolding and retracting mosquito netting for cabin-type buildings, including a unfolding mechanism 1, which is disposed inside an installation mechanism 2. A cabin mechanism 3 is disposed on the installation mechanism 2, and a cleaning mechanism 4 is disposed inside the installation mechanism 2, which is located above the unfolding mechanism 1.

[0032] The take-up and release mechanism 1 includes two first gears 101, a connecting cylinder 102 fixedly connected between the two first gears 101, a mesh cover 103 fixedly connected to the surface of the connecting cylinder 102, support bars 104 fixedly connected to both sides of the mesh cover 103, a spiral spring 105 fixedly connected to the inner wall of the connecting cylinder 102, a first bevel gear 106 fixedly connected to the side of the two first gears 101 that is far apart from each other, a second bevel gear 107 meshing above the first bevel gear 106, a second gear 108 fixedly connected to the top of the second bevel gear 107, a lead screw 109 fixedly connected to the top of the second gear 108, and a sliding plate 110 threaded onto the lead screw 109.

[0033] The mesh cover 103 and the support bar 104 are both wound around the surface of the connecting cylinder 102. The mesh cover 103 and the support bar 104 are located between the two first gears 101. The sliding plate 110 is located above the second gear 108. There are two lead screws 109. The two lead screws 109 are symmetrically distributed with the connecting cylinder 102 as the center. The end of the mesh cover 103 and the support bar 104 away from the connecting cylinder 102 is fixedly connected to the bottom of the sliding plate 110.

[0034] The cabin mechanism 3 includes a cabin shell 301. A third slide groove 306 is provided inside the cabin shell 301. A pull-out window 302 is slidably connected inside the third slide groove 306. A handle 303 is fixedly connected to the back of the pull-out window 302. A glass 304 is provided inside the pull-out window 302. Two second racks 305 are fixedly connected to the bottom of the pull-out window 302. Two fourth slide grooves 307 are provided inside the cabin shell 301. Two slots 308 are provided on the back of the cabin shell 301. The handle 303 is engaged with the slots 308. The second racks 305 are slidably connected to the fourth slide grooves 307. The second racks 305 are located on the side of the pull-out window 302 away from the handle 303.

[0035] The above solution facilitates the unfolding and retraction of the mesh cover 103 by using the cooperation of structures such as the first gear 101 and the second rack 305. Pulling up the handle 303 causes the pull-up window 302 to move upward inside the third slide groove 306. The upward movement of the pull-up window 302 drives the second rack 305 upward, thereby rotating the first gear 101. The rotation of the first gear 101 drives the connecting cylinder 102 and the first bevel gear 106, which are fixedly connected to it, to rotate. The rotation of the connecting cylinder 102 tightens the spiral spring 105, reducing the spacing between the spiral coils of the spiral spring 105, thus storing energy. At the same time, the rotation of the connecting cylinder 102 expands the mesh cover 103 and the support bar 104. The rotation of the first bevel gear 106 drives the meshed second bevel gear 107 to rotate. The rotation of the second bevel gear 107 drives the second gear 108 and the lead screw 109 to rotate. Two lead screws 109, symmetrical about the connecting cylinder 102, rotate in opposite directions, causing the sliding plate 110 to move synchronously upwards inside the first slide groove 202 and the lifting window 302. This allows the sliding plate 110 to pull the extended net cover 103 and support strip 104 out of the extension groove 204 and tighten them. At this time, the support strip 104 will fit against the surface of the cabin shell 301, so that the tightened net cover 103 blocks the gap between the lifting window 302 and the window edge. The net cover 103 and the lifting window 302 move synchronously, allowing the user to complete the dual tasks of opening the window and preventing mosquitoes with only one operation. This simplifies the operation process, improves the user experience, and is easy to operate. At the same time, it solves the problem of mosquitoes and other flying insects entering the cabin through the window during the process of opening the window and then unfolding the net cover 103, preventing mosquitoes from entering the cabin during the window opening process.

[0036] like Figures 3 to 7 As shown, the mounting mechanism 2 includes a mounting base 201. Two first sliding grooves 202 are formed inside the mounting base 201. A rotating shaft 203 is fixedly connected inside the mounting base 201. A receiving / releasing groove 204 and an air storage groove 205 are formed inside the mounting base 201. Second sliding grooves 208 are formed on both sides of the mounting base 201. A first rack 206 is slidably connected inside each of the two second sliding grooves 208. A piston 207 is fixedly connected to the side of each of the two first racks 206 that is close to each other. The air storage groove 205 is located between the two second sliding grooves 208 and communicates with them. The side of the first rack 206 near the piston 207 extends through the second sliding groove 208 into the air storage groove 205. The rotating shaft 203 is located below the air storage groove 205, and the receiving / releasing groove 204 is located behind the air storage groove 205. The size of the piston 207 is adapted to the size of the air storage groove 205.

[0037] The front of the second gear 108 meshes with the first rack 206. The rotating shaft 203 extends through the first bevel gear 106 and the first gear 101 into the interior of the connecting cylinder 102. The inner wall of the connecting cylinder 102 is elastically connected to the rotating shaft 203 via a spiral spring 105. The first gear 101 and the connecting cylinder 102 are rotatably connected to the inner wall of the mounting base 201. The second gear 108 is rotatably connected to the interior of the mounting base 201. The side of the second gear 108 penetrates the mounting base 201. The inner wall of the mounting base 201 extends into the interior of the second slide groove 208. The lead screw 109 passes through the inner wall of the mounting base 201 and extends into the interior of the first slide groove 202. The lead screw 109 is rotatably connected to the first slide groove 202. The two ends of the sliding plate 110 are slidably connected to the first slide groove 202. The first gear 101 passes through the inner wall of the mounting base 201 and extends to the rear of the mounting base 201. The mesh cover 103 and the support bar 104 both pass through the receiving and releasing groove 204 and extend to the top of the mounting base 201.

[0038] The first gear 101 extends through the surface of the outer shell 301 to the interior of the fourth slide groove 307 on the side away from the mounting base 201. The first gear 101 meshes with the second rack 305. The mounting base 201 is fixedly connected to the outer shell 301 by bolts. The sliding plate 110 is located on the side of the pull-up window 302 away from the handle 303.

[0039] The cleaning mechanism 4 includes several first grooves 401 and several second grooves 402 evenly spaced on the mounting base 201. A baffle 403 is fixedly connected to the interior of each of the first and second grooves 401, and a stop block 404 is also fixedly connected to the interior of each. The baffles 403 are elastically connected to the inner walls of the first and second grooves 401 and 402 respectively by coil springs 405. The first grooves 401 are located above the air storage tank 205, and the second grooves 402 are located on the side of the air storage tank 205. Both the first groove 401 and the second groove 402 are connected to the air storage tank 205. The stop block 404 in the second groove 402 is located on the side of the baffle 403 away from the air storage tank 205. The stop block 404 in the first groove 401 is located on the side of the baffle 403 close to the air storage tank 205. The coil spring 405 in the second groove 402 is located on the side of the baffle 403 close to the air storage tank 205. The coil spring 405 in the first groove 401 is located on the side of the baffle 403 away from the air storage tank 205. The first groove 401 is located on the side of the sliding plate 110 away from the pull-up window 302.

[0040] The above solution facilitates cleaning of the mesh cover 103 when it is retracted by the cooperation of structures such as piston 207 and baffle 403. When the pull-up window 302 is closed, the second gear 108 rotates in the opposite direction, causing the two pistons 207 to move closer to each other, increasing the air pressure inside the air storage tank 205. The air pressure causes the baffle 403 inside the first groove 401 to rotate away from the air storage tank 205, opening the channel of the first groove 401 and allowing the gas inside the air storage tank 205 to be discharged from the first groove 401. This blows air onto the mesh cover 103 at the bottom of the sliding plate 110, which is about to be retracted into the storage slot 204. The airflow blows away the mosquitoes and dust attached to the mesh cover 103, performing self-cleaning of the mesh cover 103. This prevents mosquitoes and dust from entering the device and causing damage and contamination, extending the service life of the mesh cover 103, reducing the frequency and cost of replacement, and reducing the burden of regular manual cleaning. The frequency and complexity of maintenance are reduced, saving time and effort.

[0041] The working principle and usage process of this invention are as follows: First, the mounting base 201 is bolted onto the outer shell 301 of the cabin, so that the first gear 101 located behind the mounting base 201 meshes with the second rack 305. At this time, pulling the handle 303 upward causes the pull-up window 302 to move upward inside the third slide groove 306. The upward movement of the pull-up window 302 will drive the second rack 305 to move upward, thereby causing the first gear 101 to rotate. The rotation of the first gear 101 will drive the connecting cylinder 102 and the first bevel gear 106 fixedly connected to it to rotate. The rotation of the connecting cylinder 102 will tighten the spiral spring 105, reducing the spacing between the spiral coils of the spiral spring 105, thereby storing energy. At the same time, the rotation of the connecting cylinder 102 will expand the mesh cover 103 and the support bar 1. 04, the rotation of the first bevel gear 106 will drive the rotation of the second bevel gear 107 meshing with it. The rotation of the second bevel gear 107 will drive the rotation of the second gear 108 and the lead screw 109. The two lead screws 109, which are symmetrical about the connecting cylinder 102, will rotate in opposite directions, thereby driving the sliding plate 110 to move upward synchronously with the lifting window 302 inside the first sliding groove 202. This causes the sliding plate 110 to pull out the extended net cover 103 and the support bar 104 from the inside of the retraction groove 204 and tighten them. At this time, the support bar 104 will fit against the surface of the outer shell 301 of the cabin, so that the tight net cover 103 will block the gap between the lifting window 302 and the window edge, preventing mosquitoes from entering the cabin during the opening of the window.

[0042] Simultaneously, the rotation of the two second gears 108 causes the two meshing first racks 206 to move away from each other, thereby causing the two pistons 207 to move away from each other inside the air storage tank 205. Increasing the distance between the two pistons 207 reduces the air pressure between them. This air pressure causes the baffle 403 in the second groove 402 to rotate closer to the air storage tank 205 and compress the coil spring 405, allowing external air to enter the air storage tank 205 through the second groove 402. After the pull-up window 302 stops moving, the baffle 403 will return to its original position under the elastic force of the coil spring 405, causing the air storage tank 205 to return to its original position. 5. The internal air storage is when the pull-up window 302 is closed, the second gear 108 will rotate in the opposite direction, causing the two pistons 207 to move closer to each other, increasing the air pressure inside the air storage tank 205. The air pressure causes the baffle 403 inside the first groove 401 to rotate away from the air storage tank 205, opening the channel of the first groove 401 and allowing the gas inside the air storage tank 205 to be discharged from the first groove 401. This blows air onto the mesh cover 103 at the bottom of the sliding plate 110, which is about to be put into the receiving slot 204. The airflow blows away the mosquitoes and dust attached to the mesh cover 103, thus performing self-cleaning of the mesh cover 103.
