Description

Technical Field

[0001] The utility model relates to the technical field of sealing doors, in particular to a large-scale thresholdless fully automatic inflatable sealing door. Background Art

[0002] Existing sealing doors are basically opened and closed manually, and the sealing is completed by compressing conventional rubber strips. The sealing effect is not good. Moreover, over time, after the rubber strips are deformed under pressure for many times, their deformation performance will gradually decline, and the sealing effect will gradually decline until it is completely lost. And the process of replacing the rubber strips is also rather cumbersome, greatly increasing the burden on the staff.

[0003] On the other hand, in order to meet the passage of vehicles, the prior art generally adopts a design of no threshold or movable threshold. For this no-threshold design, due to the lack of a fitting surface between the door leaf and the threshold along the opening and closing direction, conventional rubber strips often cannot achieve good sealing; while the movable threshold can ensure a better sealing effect, but since this kind of movable threshold is all manual structure, the disassembly and installation preparation time is long, and it cannot meet the requirement of the vehicle for quick response and passage.

[0004] Therefore, while ensuring the fast passing performance of the vehicle, how to improve the sealing performance of the sealing door is one of the problems to be solved urgently. Content of the Utility Model

[0005] In order to solve at least one technical problem mentioned in the background art, the purpose of the utility model is to provide a large-scale thresholdless fully automatic inflatable sealing door, which can greatly improve the sealing performance and reliability of the sealing door, and at the same time ensure the fast passing ability of the vehicle.

[0043] The technical solutions in the embodiments of the present utility model will be described clearly and completely below. Apparently, the described embodiments are only a part of the embodiments of the present utility model, rather than all of them. All other embodiments obtained by those of ordinary skill in the art based on the embodiments of the present utility model without creative efforts shall fall within the protection scope of the present utility model.

[0044] Embodiment 1:

[0045] Please refer to Figure 1 、 Figure 2 and Figure 3 , this embodiment provides a large-scale thresholdless fully automatic inflatable sealing door, including: a door frame 1, a door leaf 2, an inflatable rubber strip 3, an air charging and discharging system, a door opener 4 and a locking mechanism 5.

[0046] The door frame 1 is made of an angle steel frame, and a plurality of mounting plates are arranged around it for mounting a hinge 10, a door opener 4 and a locking mechanism 5 respectively.

[0047] The door leaf 2 is connected to the door frame 1 through a hinge 10 and can rotate around the door frame 1. Moreover, the door leaf 2 is in clearance fit with the door frame 1 to form a clearance 11 around it.

[0048] The door opener 4 is installed on the door frame 1 and is used to drive the door leaf 2 to rotate relative to the door frame 1. Specifically, the door opener 4 includes a motor 41 and a connecting rod 42. The motor 41 is installed on the door frame 1, one end of the connecting rod 42 is connected to the output shaft of the motor 41, and the other end is connected to the door leaf 2.

[0049] The locking mechanism 5 locks the door leaf 2 in the closed state. Please refer to Figure 6 , the locking mechanism 5 includes a bolt 51 arranged on the door frame 1 and a bolt seat 52 arranged on the door leaf 2. When the bolt 51 is inserted into the bolt seat 52, the locking is completed.

[0050] It is worth mentioning that a handwheel for driving the bolt 51 to move towards / away from the bolt seat 52 is also arranged on the door frame 1.

[0051] The inflatable rubber strip 3 is arranged on the outer edge of the door leaf 2, specifically in the clearance 11 between the door leaf 2 and the door frame 1. The inflatable rubber strip 3 is a rubber strip with a hollow cavity. By charging and discharging the hollow cavity, the expansion / contraction of the rubber strip can be realized.

[0052] Specifically, please refer to Figure 2 and Figure 3 , in the inflated state, the outer side of the inflatable rubber strip 3 is in contact with the door frame 1 to achieve sealing; as shown by the dotted line, in the deflated state, the outer side of the inflatable rubber strip 3 is separated from the door frame 1, thus releasing the sealed state, and the door leaf 2 and the door frame 1 can rotate freely.

[0053] In order to install the inflatable rubber strip 3, an installation groove 21 for installing the inflatable rubber strip 3 is arranged on the outer edge of the door leaf 2.

[0054] In order to enhance the airtightness, a plurality of convex strips 31 are arranged on the outer side of the inflatable rubber strip 3 in this embodiment. In the inflated state, the rubber strip expands, pushing up the convex strips one by one, and contacting and squeezing with the door frame plane to form multiple sealing lines, which can enhance the airtightness.

[0055] An inflation and deflation system, connected to the inflatable strip 3, is used to inflate and deflate the inflatable strip 3.

[0056] As Figure 7 shown, the inflation and deflation system of this embodiment uses double gas cylinders for dual-channel parallel gas supply to increase the gas supply efficiency. Taking one of the channels as an example, the gas transmission pipeline of the gas cylinder is connected to an angle stop valve through a spherical joint kit, and then the gas is sequentially transported to the inflatable strip 3 through a solenoid valve, a pressure reducing valve, and a filter to achieve inflation.

[0057] In addition, the inflatable strip 3 is also connected to the exhaust port through a solenoid valve and an angle stop valve, thereby achieving deflation.

[0058] It is worth mentioning that this embodiment also has a function of real-time monitoring of the gas cylinder pressure and low-pressure alarm. By setting a pressure sensor on the gas transmission pipeline, when the detected air pressure is outside the set range, an alarm is issued.

[0059] Embodiment Two:

[0060] In order to further enhance the airtightness, Embodiment Two is improved on the basis of Embodiment One, and a double-seal design is proposed to improve the reliability of the seal.

[0061] Please refer to Figure 2 and Figure 3 , an installation part 6 extending outward is further provided on the outer edge of the door leaf 2, and rubber is provided on the side of the installation part 6 facing the door frame 1. In the closed state of the door, the rubber abuts against the edge of the door frame 1 to achieve a second seal.

[0062] When considering the threshold-free design of the sealed door, conventional rubber cannot be installed on the lower side of the door leaf. Therefore, in this embodiment, the rubber on the lower side and other sides is designed separately. Specifically, the rubber includes two types: a P-shaped rubber strip 71 and a rubber plate 72.

[0063] Please refer to Figure 2 , the P-shaped rubber strip 71 is provided on the upper side and the left and right sides of the door leaf 2. Taking the upper side as an example, the head of the P-shaped rubber strip 71 faces the door frame, and the tail is fixed to the installation part 6.

[0064] Please refer to Figure 3 , the rubber plate 72 is provided on the lower side of the door leaf 2. One side of the rubber plate 72 is fixed to the installation part 6, and the other side is in contact with the door frame 1. And the width of the rubber plate 72 is greater than the width of the gap 11. In the natural state, the rubber plate 72 is as shown by the dotted line, and the rubber plate 72 is in contact with the door frame 1 / ground during the working process, forming a curved shape.

[0065] Please refer to Figure 4 and Figure 5, the outer shapes of the P-shaped rubber strip 71 and the rubber plate 72 are quite different, so voids will be formed. Therefore, a caulking rubber block 73 is provided at the junction of the P-shaped rubber strip 71 and the rubber plate 72. The two sides of the caulking rubber block 72 are respectively fitted with the P-shaped rubber strip 71 and the rubber plate 72, so as to avoid the generation of voids at the junction.

[0066] For those skilled in the art, it is obvious that the present invention is not limited to the details of the above exemplary embodiments, and the present invention can be implemented in other specific forms without departing from the spirit or basic characteristics of the present invention. Therefore, from any point of view, the embodiments should be regarded as exemplary and non-restrictive. The scope of the present invention is defined by the appended claims rather than the above description. Therefore, all changes falling within the meaning and scope of the equivalent elements of the claims are intended to be embraced by the present invention.
