Description

Technical Field

[0001] This utility model relates to the field of tunnel drainage technology, and more specifically, to an automatic folding insect-proof skylight. Background Technology

[0002] A folding skylight is a type of skylight with a special structure and function. It can be opened or closed by folding to adapt to different usage needs. For example, installing a folding skylight in an attic can increase indoor lighting and ventilation, while improving living comfort. Therefore, there is a special need to design an automatic folding insect-proof skylight.

[0003] Currently, in the use of folding skylights, insect-proof nets are often installed inside the window frame to prevent mosquitoes from entering the room during the summer. For example, the glass greenhouse folding insect-proof net skylight structure announced by patent number CN220521772U uses an elastic locking structure to install the insect-proof net, which effectively improves the insect-proof effect and is easy to clean.

[0004] However, actual research revealed that although insect nets are mostly installed using a snap-fit ​​structure, making them easy to disassemble, their surface quickly becomes covered in dust because they are always open. In practical applications, insect nets are often not needed when windows are closed, such as during rain or strong winds with lots of dust. Furthermore, the nets need to be removed when cleaning or closing windows, which is very inconvenient. Currently, most skylights do not have a good automatic insect net storage structure; instead, the nets are directly installed on the frame, resulting in a relatively fixed structure.

[0005] Therefore, in response to the above problems, the applicant needs to design an automatic folding insect-proof skylight to solve the problem. Utility Model Content

[0006] The purpose of this invention is to provide an automatic folding insect-proof skylight, which uses an insect-proof net that can be automatically retracted for storage when not in use, and the window is closed by the storage structure, without adding any additional electronic equipment, thus solving the problems mentioned in the background art.

[0007] To solve the above-mentioned technical problems, this utility model provides an automatic folding insect-proof skylight, comprising: a window body one rotatably connected to the window frame; a window body two rotatably connected to one end of the window body one; a slider one rotatably connected to the other end of the window body two; an insect net frame fixed at the bottom of the window frame; one side of the insect net frame is connected to one end of a nylon mesh, and the other end of the nylon mesh is wound around a rotating cylinder; a rotating shaft at one end of the rotating cylinder passes through the inner cavity of the insect net frame and is connected to a gear; the gear meshes with a rack installed in the inner cavity; a rotating shaft at the other end of the rotating cylinder passes through the inner cavity of the insect net frame and is connected to a motor; and a slider two fixed at the top of the motor slides in a track inside the window frame.

[0008] The opening through which the rotating shaft of the insect net frame passes is fitted with two pieces of sponge pads, which are designed to be corrosion resistant.

[0009] A drive plate is fixed to one side of the second slider. The drive plate can be inserted into the socket on one side of the third slider. The third slider shares a slide rail with the second slider and the third slider is connected to the first slider. The third slider has a vertical slide rail inside that communicates with the socket. A block slides up and down in the slide rail. The block can be inserted into the square socket corresponding to the drive plate and fits. A spring is connected to the bottom of the block and the bottom of the slide rail. The corner of the top of the block facing the drive plate is designed with an arc surface.

[0010] The slider three has a horizontal slide rail inside, and a pull block is slidably connected inside the slide rail. One side of the pull block is connected to the bottom of the insert block with a pull rope. The pull rope passes through the rope channel inside the slider three. The other side of the pull block is fixed with a stop block that passes through the slider three, and the stop block also slides in the slide rail inside the window frame.

[0011] The slider 1 has an adsorption metal block installed on the side facing the drive plate. Two sliding rods fixed on one side of the adsorption metal block are inserted into the slider 1. The slider 1 and the adsorption metal block are connected by a spring 2 sleeved on the outside of the sliding rods. When the slider 1 slides to one end of the slide and the window 2 is fully opened, the adsorption metal block can be adsorbed by the magnetic strip set on the inner wall of the slide.

[0012] A circular plate is fixed to one end of the slider inside the first slider, and the circular plate also slides inside the first slider.

[0013] The inner wall of the square socket into which the insert plate is inserted is bonded with an elastic rubber pad, and the elastic rubber pad is designed on the side of the insert plate without a curved surface.

[0014] Both slider two and slider three have cushioning foam pads adhered to one side.

[0015] The beneficial effects of this utility model are:

[0016] 1. This utility model, through the design of the insect net frame and its internal components, allows the nylon mesh to be unfolded for protection when insect prevention is needed, and the nylon mesh to be stored away when the skylight needs to be closed or cleaned. It is very convenient to use and avoids the problem of dust easily accumulating when unfolded for a long time.

[0017] 2. This utility model, through the design of driving plate, insert block, spring, pull block, pull rope and stop block, can realize the synchronous operation of the insect net unfolding and the window folding and opening, without the need for additional drive to open the window, which is very energy-saving and reduces the overall weight.

[0018] 3. In terms of the stability design of the second window, when the stop block reaches the end of its slide, the adsorption metal block on the first slider is simultaneously adsorbed by the magnetic strip at the end of its slide. At the same time, the adsorption metal block is elastically connected to the third slider and can cooperate with the stop block, thereby making the insert block move down and disengage from the square insertion port of the insert plate and remain stable.

[0030] The present invention will now be described in further detail with reference to the accompanying drawings. These drawings are simplified schematic diagrams, illustrating only the basic structure of the present invention, and therefore only show the components relevant to the present invention.

[0031] like Figures 1-9 As shown, the present invention provides an automatic folding insect-proof skylight, comprising: a window frame 1 rotatably connected to a window body 11, a window body 12 rotatably connected to one end of the window body 11, a slider 13 rotatably connected to the other end of the window body 12, an insect net frame 2 fixed at the bottom of the window frame 1, one side of the insect net frame 2 being connected to one end of a nylon mesh 21, and the other end of the nylon mesh 21 being wound around a rotating cylinder 22, one end of the rotating cylinder 22 having a shaft that passes through the inner cavity of the insect net frame 2 and is connected to a gear 23, the gear 23 meshing with a rack 24 installed in the inner cavity, the other end of the rotating cylinder 22 having a shaft that passes through the inner cavity of the insect net frame 2 and is connected to a motor 25, and a slider 26 fixed at the top of the motor 25 sliding in a track inside the window frame 1.

[0032] By designing the insect net frame 2 and its internal components, in the initial state, the nylon mesh 21 is wound around the rotating drum 22. After the window is opened, the motor 25 can be started, and the rotating drum 22 rotates, causing the gear 23 to rotate and move by meshing with the rack 24. The motor 25 moves by sliding along the slide rail inside the window frame 1 through the top-fixed slider 26, so that the rotating drum 22 rotates and moves while unwinding until the rotating drum 22 is in contact with the inner wall of the other side of the insect net frame 2, at which point the nylon mesh 21 can be unfolded for protection. When the skylight needs to be closed or cleaned, the nylon mesh 21 can be stored away, which is very convenient to use and avoids the problem of dust easily accumulating when unfolded for a long time. It should be noted that the inner wall of the insect net frame 2 is aligned with the inner wall of the window frame 1, and the edge of the net is made of non-woven fabric and is in contact with the inner side of the insect net frame 2 to prevent mosquitoes from entering.

[0033] A drive plate 28 is fixed to one side of slider 26. The drive plate 28 can be inserted into the socket on one side of slider 3. Slider 3 and slider 226 share a slide rail, and slider 33 is connected to slider 13. Slider 33 has a vertical slide rail inside that communicates with the socket. A plug 31 slides up and down in the slide rail. The plug 31 can be inserted into the square socket corresponding to the drive plate 28 and fits. A spring 34 is connected to the bottom of the slide rail. The corner of the top of the plug 31 facing the drive plate 28 is designed with an arc surface. Slider 33 has a horizontal slide rail inside. A pull block 33 is slidably connected inside the slide rail. A pull rope 32 is connected to the bottom of the plug 28 on one side of the pull block 33. The pull rope 32 passes through the rope channel inside slider 33. A stop block 35 is fixed to the other side of the pull block 33 and passes through slider 33. The stop block 35 also slides in the slide rail inside the window frame 1.

[0034] Since adding a motor 25 to the original improvements might increase the weight of the equipment, a design was implemented to drive the insert plate 28, insert block 31, spring 34, pull block 33, pull rope 32, and stop block 35. Initially, the insert plate 28 is inserted into one side of the slot on slider 3, and the insert block 31 is inserted into the corresponding square slot on the insert plate 28. When the nylon mesh 21 unfolds and slider 26 moves, the insert plate 28, through the insert block 31, drives slider 3 to move. Slider 3 then drives slider 13 to move, causing one end of window 2 12 to move and rotate. The window folds and rotates with the window 11, opening the window. When the stop block 35 reaches the end of its track, the window 11 opens to the optimal angle, and the stop block 35 can no longer move. The slider 3 continues to move, causing the pull block 33 to slide in the slider 3, which then pulls the insert block 31 down to disengage it from the square insert corresponding to the drive plate 28. At this time, the nylon mesh 21 can continue to unfold. In this way, the unfolding and folding of the window are synchronized, without the need for additional drive to open the window, which is very energy-efficient and reduces weight.

[0035] A metal block 14 is installed on the side of slider 13 facing the drive plate 28. Two sliding rods 16 fixed on one side of the metal block 14 are inserted into the inside of slider 13. A spring 2 15 is connected to slider 13 and metal block 14 and sleeved on the outside of sliding rod 16. When slider 13 slides to one end of the slide and window 2 12 is fully opened, the metal block 14 can be attracted to the magnetic strip (not shown in the figure) set on the inner wall of the slide. A circular plate is fixed at one end of the sliding rod 16 inside slider 13, and the circular plate also slides inside slider 13.

[0036] In the stability design of form 212, when block 35 reaches the end of its slide, the adsorption metal block 14 on slider 13 simultaneously adsorbs onto the magnetic strip at the end of its slide, causing the insert 31 to move down and disengage from the square insertion port of insert plate 28, thus maintaining stability. Meanwhile, after block 35 can no longer move, slider 3 and slider 13 still need to move a small distance. Therefore, slider 16 can slide into slider 13 to meet the movement requirements. After slider 226 and slider 33 separate, the compressed spring 215 drives slider 33 and slider 13 to move back. At this time, spring 134 will also cause block 35 to... When the insert block 31 is reset, the insert plate 28 is driven to re-insert into the slot on one side of the slider 3, and the slider 3 and the slider 2 26 are in contact. Since the corner of the top of the insert block 31 facing the insert plate 28 is designed with an arc surface, the insert block 31 can be pressed down to insert into its square slot. Then the slider 3 and the slider 13 can be reset, so that the window 11 and the window 2 12 can be folded back to close the window. Note that when the slider 2 26 pushes the slider 3 to reset, the circular plate is squeezed, which can drive the slide rod 16 and the adsorbent metal block 14 to detach from the magnetic strip, avoiding the separation caused by the spring 2 15 and resulting in damage.

[0037] The inner wall of the square socket into which the insert plate 28 is inserted by the insert block 31 is bonded with an elastic rubber pad 29, and the elastic rubber pad 29 is designed on the side of the insert block 31 without the curved surface. The second slider 26 and the third slider 3 are both bonded with a cushioning foam pad 4. The upper and lower ends of the opening through which the rotating shaft of the insect net frame 2 passes are bonded with two pieces of sponge pad 27, and the sponge pad 27 is designed to be corrosion resistant.

[0038] Furthermore, in terms of protective optimization design, the elastic pad 29 can prevent excessive squeezing force when the insert plate 28 is moved to open the window. The elastic pad 29 has elasticity and deformation capability, and its surface is smooth, preventing the insert block 31 from getting stuck due to horizontal squeezing force when it detaches from the insert plate 28, which could cause the pull rope 32 to break, etc. It is very practical. When the insert plate 28 moves down and detaches, the slider 26 pushes the slider 33. The cushioning foam pad 4 can protect the two larger sliders 26 and 33 from the collision force generated by their collision with the slide rail. Finally, the sponge pad 27 can protect the opening through which the pivot passes. It is soft and has good deformation capability, so it does not affect the back and forth movement of the pivot.

[0039] Working principle: When the window is opened, motor 25 is started, and drum 22 rotates, causing it to move while unwinding. During this process, insert plate 28 moves through insert block 31, which in turn moves slider 3. Slider 3 moves slider 13, causing one end of window 12 to move and rotate, resulting in a folding motion between it and window 11, thus opening the window. When stop block 35 reaches the end of its track, the magnetic metal block 14 on slider 13 simultaneously attracts the magnetic strip at the end of its track, opening window 11 to the optimal angle. Stop block 35 then cannot move, while slider 33 continues to move, attracting the magnetic block 14. 4 cannot be moved, but the slider 16 can slide into the slider 13, so that the pull block 33 slides in the slider 3, and then pulls the insert block 31 down to disengage it from the square socket corresponding to the drive plate 28. Then the nylon mesh 21 unfolds for protection. Finally, when it is rolled up, the drive plate 28 is reinserted into the socket on one side of the slider 3, and the slider 3 and the slider 26 are in contact. Since the corner of the top of the insert block 31 facing the drive plate 28 is a curved surface design, the insert block 31 can be pressed down to insert into its square socket. Then the slider 3 and the slider 13 can be reset, so that the window 11 and the window 212 can be folded back to close the window.
