Description

TECHNICAL FIELD

[0001] The present application relates to the field of door and window structures, and in particular to an inflatable sealed door and window. BACKGROUND

[0002] In some special occasions, such as a medicine storage, the door and window are required to have high sealing performance. In order to obtain high sealing performance, a sealing strip that can be inflated with gas is arranged at the closed part of the door and window to ensure that the sealing strip is tightly pressed at the closed part of the door and window, thereby achieving excellent sealing performance.

[0003] For example, a new inflatable sealed multi-purpose energy-saving and environmentally friendly door and window with the publication number CN215213217U has a fixed outer frame, a mounting frame rotatably connected to the outer frame, and an inflatable belt mounted at the closed part of the mounting frame and the outer frame. The inflatable belt is inflated with gas through a gas nozzle to achieve a sealing effect.

[0004] According to the related technology described above, the inflatable belt has only a single layer of contact on the side facing the outer frame, and the sealing performance is poor. SUMMARY

[0005] In order to improve the sealing performance, the present application provides an inflatable sealed door and window.

[0006] The inflatable sealed door and window provided by the present application adopts the following technical solution.

[0007] An inflatable sealed door and window includes a fixed sealing frame, a door and window body that can rotate close to the sealing frame, and a sealing ring arranged in the sealing frame and capable of being inflated with gas. The sealing ring has an inner concave surface recessed towards the sealing frame on the side facing the door and window body. The two sides of the sealing ring close to the inner concave surface can abut against the door and window body.

[0008] By adopting the above technical solution, during the process of inflating the sealing ring with gas and expanding, the inner concave surface moves towards the door and window body to force the sealing ring on the two sides of the inner concave surface to tightly abut against the door and window body, thereby achieving double-layer sealing by a single sealing ring and improving the sealing effect.

[0009] Optionally, the door and window body includes a rotating body that can rotate and a plug-in frame fixedly connected to the rotating body. The plug-in frame is plugged into the inner ring of the sealing frame, and the two sides of the sealing ring close to the inner concave surface can abut against the outer ring surface of the plug-in frame.

[0010] By adopting the above technical solution, the sealing performance achieved by the sealing ring does not rely too much on the rotation angle of the rotating body. Even if the rotating body and the sealing ring are not completely parallel and close to each other, the sealing frame can still achieve uniform and excellent sealing effect everywhere.

[0011] Optionally, the sealing ring is fixedly connected with a sleeve at a position close to the inner concave surface farthest from the insertion frame, the sleeve is sleeved with a mounting rod detachably connected with the sealing frame and penetrating through the sealing ring, one end of the mounting rod in the sleeve is fixedly connected with a rod end piece, and the end of the sleeve for inserting the mounting rod is detachably connected with a pipe mouth piece capable of preventing the rod end piece from separating from the sleeve.

[0012] By adopting the above technical scheme, when the sealing ring is inflated, if the air pressure is too large, the inner concave surface of the sealing ring is easily compressed too much, and cracks are easily generated in the inner concave surface of the sealing ring due to excessive compression, which reduces the service life of the sealing ring, and the sealing ring is prone to air leakage under a long-term large air pressure, and the sealing performance is easily reduced. Therefore, the sleeve and the mounting rod are used to connect the position of the formed inner concave surface of the sealing ring to prevent the position of the formed inner concave surface of the sealing ring from being compressed too much.

[0013] Optionally, a return spring is arranged between the rod end piece and the pipe mouth piece to force the pipe mouth piece away from the insertion frame.

[0014] By adopting the above technical scheme, when the gas in the sealing ring is released, the return spring can provide an external force to force the position of the formed inner concave surface of the sealing ring away from the insertion frame, so that the position of the formed inner concave surface of the sealing ring can be smoothly restored after a long time of compression, thereby facilitating long-term use of the sealing ring.

[0015] Optionally, the mounting rod is hingedly connected with a plurality of circumferential rods, all the circumferential rods are fixedly connected with a sleeved compression rubber piece, the inner circumferential surface of the compression rubber piece is fixedly connected with the mounting rod, the compression rubber piece abuts against the opening periphery of the sealing ring for penetrating the mounting rod, the mounting rod is fixedly connected with a limiting block capable of abutting against the circumferential rod, and the limiting block is located at the side of the circumferential rod facing the sleeve.

[0016] By adopting the above technical scheme, the compression rubber piece can abut against the inner wall of the sealing ring, and can be tightly pressed against the hole periphery of the sealing ring for penetrating the mounting rod under the action of a large air pressure in the sealing ring, so that the sealing ring is not prone to air leakage. On the one hand, the circumferential rod can force the compression rubber piece to be tightly pressed against the inner wall of the sealing ring, and is not easily extruded into the hole of the sealing ring for penetrating the mounting rod by the air pressure, and on the other hand, when the compression rubber piece is put into the sealing ring, the compression rubber piece can tightly adhere to the mounting rod, thereby facilitating the installation work.

[0017] Optionally, a torsional spring is arranged at the rotation point of the circumferential rod to force the circumferential rod to rotate towards the limiting block.

[0018] By adopting the above technical scheme, after the circumferential rod and the compression rubber piece are completely put into the sealing ring, the torsional spring can force the circumferential rod to rotate to ensure that the compression rubber piece is fully unfolded, and to ensure that the compression rubber piece can tightly adhere to the inner wall of the sealing ring.

[0019] Optionally, the upper convex surface is inserted into the hole of the sealing ring.

[0020] By adopting the above technical scheme, the sealing performance of the rubber pressing sheet on the hole of the sealing ring is further improved.

[0021] Optionally, the mounting rod is threadedly connected with a rod sleeve, and each end of the circumferential rod away from the rotation point can enter the rod sleeve.

[0022] By adopting the above technical scheme, the ends of all circumferential rods away from the respective rotation points are close to the mounting rod, so that the circumferential rods are gathered for more convenient installation work.

[0023] Optionally, the mounting rod is threadedly connected with a gasket ring capable of abutting against the inner wall of the sealing frame, the gasket ring is capable of abutting against the end surface of the rod sleeve away from the circumferential rod, and the mounting rod is threadedly connected with a fastening nut capable of abutting against the outer wall of the sealing frame.

[0024] By adopting the above technical scheme, the position of the mounting rod is fixed, and when there is a small difference in specifications at different positions of the sealing frame, the gasket ring and the rod sleeve can be adjusted.

[0025] Optionally, a frame opening is arranged at the position of the side of the sealing frame away from the rotating body and opposite to the gasket ring and the rod sleeve.

[0026] By adopting the above technical scheme, after the mounting rod is inserted into the sealing frame, the gasket ring is ensured to abut against the inner wall of the sealing frame, and the rubber pressing sheet is ensured to abut against the inner wall of the sealing ring.

[0027] In summary, the present application at least has the following beneficial effects.

[0028] The single sealing ring performs double-layer sealing to improve the sealing effect. BRIEF DESCRIPTION OF DRAWINGS

The surface of the sealing grommet 3 facing the insertion frame 33 is formed with an inner concave surface 31, the side of the inner concave surface 31 away from the insertion frame 33 is recessed, so that the two sides of the sealing grommet 3 formed with the inner concave surface 31 can be tightly attached to the insertion frame 33.

[0034] The implementation principle of the inflatable sealing door and window of Example One of the application is that the rotating body 32 is rotated, the insertion frame 33 is inserted into the inner periphery of the sealing frame 1, and then gas is filled into the sealing grommet 3, so that the two sides of the sealing grommet 3 located at the inner concave surface 31 can be tightly attached to the insertion frame 33 to achieve sealing effect.

[0035] Example Two Example Two of the application discloses an inflatable sealing door and window, referring to Figure 3 and Figure 4, and the difference between the embodiment one is that the sealing ring 3 is provided with a sleeve 34 near the position farthest from the inner recess 31 of the plug-in frame 33, the sleeve 34 and the sealing ring 3 are fixed by hot melting or bonding, the sleeve 34 is coaxially sleeved with a mounting rod 35 at the end farthest from the inner recess 31, the mounting rod 35 is penetrated in the sealing ring 3 and the sealing frame 1 at the end farthest from the sleeve 34, and the mounting rod 35 and the sealing frame 1 are detachably connected, so that when the air pressure in the sealing ring 3 is larger, the position of the sealing ring 3 forming the inner recess 31 is not easy to be excessively compressed. The end of the mounting rod 35 in the sleeve 34 is coaxially fixedly connected with a rod end piece 36, the circumferential outer wall of the end of the sleeve 34 for inserting the mounting rod 35 is threadedly connected with a pipe mouth piece 37, the rod end piece 36 and the pipe mouth piece 37 are directly abutted with a return spring 38 sleeved on the mounting rod 35, the return spring 38 forces the pipe mouth piece 37 away from the rod end piece 36, so that when the sealing ring 3 is deflated, the position of the sealing ring 3 forming the inner recess 31 can be smoothly restored to the state before being compressed by the sleeve 34.

[0036] With reference to Figure 3 and Figure 4 Each mounting rod 35 is hinged with a plurality of circumferential rods 39 outside the sleeve 34, all circumferential rods 39 in the same group are uniformly arranged around the axis of the corresponding mounting rod 35, and each circumferential rod 39 can be rotated from a state that the length direction is consistent with the length direction of the corresponding mounting rod 35 to a state that the straight line where the length direction is located intersects with the axis of the corresponding mounting rod 35.
