Description

Technical Field

[0001] This utility model relates to the field of expansion cabin technology, and in particular to an inflatable and sealed expansion cabin. Background Technology

[0002] An extended cabin is a cabin structure with high flexibility and space expandability. Due to its large internal space and stable and reliable structure, it is widely used in military, medical, and emergency response fields. It mainly consists of a fixed cabin and a movable cabin. When it is necessary to expand the internal space, the movable cabin can be opened.

[0003] When the application site has high requirements for the airtightness of the cabin, the current side compartments of the expansion cabin are movable parts, making it difficult to meet the requirements for airtightness and water resistance. Therefore, this application provides an inflatable and sealed expansion cabin to meet the requirements. Utility Model Content

[0004] This utility model provides an inflatable sealed expansion chamber to solve the problem that the airtightness and water resistance of the chamber are difficult to meet the requirements for applications with high requirements for the airtightness of the chamber.

[0005] To solve the above-mentioned technical problems, this utility model provides the following technical solution: An inflatable, sealed expansion chamber includes a fixed chamber and a movable chamber slidably connected to the side of the fixed chamber, and further includes: A sealing mechanism, comprising a top strip fixed to the top of the inner wall of the fixed chamber, a C-shaped strip fixed to the bottom of the top strip, the C-shaped strip fixed to the inner wall of the fixed chamber, two extensions fixed to the bottom of the top strip, an inflatable sealing strip connected between the two extensions and the inner wall of the C-shaped strip, and an inflatable connector connected to the outer wall of the inflatable sealing strip. When the active cabin is opened, air is inflated into the inflatable sealing strip, causing the inflatable sealing strip to bulge and adhere to the outer wall of the active cabin.

[0006] Preferably, the side of the extension and the inner wall of the C-shaped strip are both fixed with protrusions, and the side wall of the inflatable sealing strip is provided with a recess corresponding to the protrusion, with the protrusion being inserted into the recess.

[0007] Preferably, the inner wall of the inflatable sealing strip has a wavy sealing surface on the side corresponding to the outer wall of the active cabin.

[0008] Preferably, buffer components are installed on the sides of the top bar and the top of the movable cabin, and the buffer components are used for buffering after the movable cabin is opened and closed.

[0009] Preferably, the buffer assembly includes two L-shaped strips fixed to the side of the top strip, with a rubber buffer strip snapped between the two L-shaped strips. A buffer plate is fixed to the side of the movable cabin. When the movable cabin is opened, the buffer plate squeezes the rubber buffer strip, and the rubber buffer strip deforms under pressure.

[0010] Preferably, the buffer assembly further includes a connecting plate fixed to the top of the movable cabin. Two L-shaped strips are fixed to the side of the connecting plate near the top bar. A rubber buffer strip is snapped between the two L-shaped strips. When the movable cabin is closed, the connecting plate causes the rubber buffer strip to fit against the side of the top bar, and the rubber buffer strip deforms under pressure.

[0011] Preferably, both the first rubber buffer strip and the second rubber buffer strip have through grooves at their ends.

[0012] Preferably, the top bar has a bent portion on its side, and the bent portion is fixed to the side of the fixed compartment.

[0013] Compared with the prior art, this utility model has at least the following beneficial effects: In the above solution, by setting a top strip, a C-shaped strip, and an inflatable sealing strip, when the movable compartment is opened, air is inflated into the inflatable sealing strip, causing the inflatable sealing strip to bulge and fit against the outer wall of the movable compartment, thereby improving the sealing performance between the fixed compartment and the movable compartment, thus adapting to application environments with high sealing requirements.

[0014] By setting rubber buffer strip one and rubber buffer strip two, when the movable cabin is opened, the buffer plate squeezes rubber buffer strip one, and rubber buffer strip one deforms under pressure. The deformation of rubber buffer strip one reduces the impact force when the movable cabin opens. When the movable cabin is closed, the movable cabin causes rubber buffer strip two to contact the side of the top strip. The deformation of rubber buffer strip two reduces the impact force when the movable cabin closes. The deformation of rubber buffer strip one and rubber buffer strip two reduces the impact force when the movable cabin is opened and closed, thereby effectively protecting the connection position between the movable cabin and the fixed cabin and effectively preventing damage to the connection position due to excessive force.

According to specific needs, those skilled in the art can adjust or modify these devices and environments, and such adjustments or modifications are still included in the scope of the appended claims. Detailed Implementation

[0018] The following is a detailed description of an inflatable sealed expansion chamber provided by this utility model, in conjunction with the accompanying drawings and specific embodiments. It should be noted that, to make the embodiments more detailed, the following embodiments are the best and preferred embodiments; those skilled in the art can also use other alternative methods to implement some known technologies; and the accompanying drawings are only for more specific description of the embodiments and are not intended to specifically limit this utility model.

[0019] like Figures 1-7 As shown, an embodiment of this utility model provides an inflatable sealed expansion chamber, including a fixed chamber 1 and a movable chamber 2 slidably connected to the side of the fixed chamber 1. A hatch is installed on the side of the fixed chamber 1; opening the hatch allows entry into the expansion chamber, and closing the hatch seals the interior space of the expansion chamber. The expansion chamber also includes: The sealing mechanism 3 includes a top strip 4 fixed to the top of the inner wall of the fixed chamber 1, a C-shaped strip 5 fixed to the bottom of the top strip 4, the C-shaped strip 5 fixed to the inner wall of the fixed chamber 1, two extensions 6 fixed to the bottom of the top strip 4, an inflatable sealing strip 8 connected between the two extensions 6 and the inner wall of the C-shaped strip 5, and an inflation connector 9 connected to the outer wall of the inflatable sealing strip 8, the inflation connector 9 being a valve. When the movable chamber 2 is opened, air is inflated into the inflatable sealing strip 8. The inflatable sealing strip 8 expands and fits against the outer wall of the movable chamber 2. The fixed chamber 1 provides a sliding support base for the movable chamber 2. The movable chamber 2 can switch between opening to expand space and closing to save space by sliding along the inner wall of the fixed chamber 1, meeting the space requirements of different usage scenarios. The top strip 4, as the core load-bearing component of the sealing mechanism 3, provides a stable installation benchmark for the C-shaped strip 5 and the extension 6, ensuring the accurate position of the sealing components. The C-shaped strip 5 and the extension 6 cooperate to form the installation frame of the inflatable sealing strip 8, fixing the inflatable sealing strip 8 in the preset position and preventing it from shifting when not inflated. The inflation connector 9 provides an inflation channel for the inflatable sealing strip 8, which can be easily connected to an air pump through an air pipe to achieve rapid inflation. After inflation, the expanded inflatable sealing strip 8 can fit tightly against the outer wall of the movable chamber 2, filling the gap between the fixed chamber 1 and the movable chamber 2, greatly improving the sealing performance of the connection between the two. It is suitable for scenarios with high requirements for dustproof, waterproof or air leakage prevention, ensuring that the equipment or items inside the chamber are not affected by the external environment.

[0020] like Figure 3 As shown in this embodiment, both the side of the extension 6 and the inner wall of the C-shaped strip 5 are fixed with protrusions. The side wall of the inflatable sealing strip 8 is provided with a recess corresponding to the protrusion. The protrusion is locked in the recess. The locking structure of the protrusion and the recess can firmly fix the inflatable sealing strip 8 between the extension 6 and the C-shaped strip 5, preventing the inflatable sealing strip 8 from shifting or falling off due to air pressure during inflation. This ensures that the inflatable sealing strip 8 is always aligned with the gap between the fixed chamber 1 and the movable chamber 2, ensuring a stable sealing effect. At the same time, this locking structure can also restrain the inflatable sealing strip 8 within the installation frame after deflation, preventing it from shifting due to its own elastic contraction, thus preparing it for the next inflation and sealing, and improving the reliability of the sealing mechanism 3 for repeated use.

[0021] like Figure 3 As shown in this embodiment, the inner wall of the inflatable sealing strip 8 has a wavy sealing surface on one side corresponding to the outer wall of the movable chamber 2. Compared with the planar structure, the wavy sealing surface can make the two fit more tightly, further improving the sealing performance and effectively preventing dust, moisture or airflow from seeping in through the gap. At the same time, the wavy structure has a certain degree of deformation adaptability. Even if there is slight unevenness on the outer wall after the movable chamber 2 slides, the wavy sealing surface can fit the uneven area through local deformation, avoiding sealing failure due to local gaps, enhancing the compatibility of the sealing mechanism 3 with chamber processing errors or assembly deviations, and ensuring the stability of the sealing effect.

[0022] like Figure 3As shown in this embodiment, buffer components 15 are installed on the side of the top bar 4 and the top of the movable cabin 2. The buffer components 15 are used for buffering after the movable cabin 2 is opened and closed. When the movable cabin 2 is opened or closed, it will collide with the fixed cabin 1 due to sliding inertia. The buffer components 15 can absorb the impact force generated by the collision through its own deformation, so as to prevent the connection between the movable cabin 2 and the fixed cabin 1 from being worn, deformed or broken due to long-term impact and excessive force, thus extending the overall service life of the extended cabin.

[0023] like Figure 3 As shown in this embodiment, the buffer assembly 15 includes two L-shaped strips 10 fixed to the side of the top strip 4, with a rubber buffer strip 11 snapped between the two L-shaped strips 10. A buffer plate 16 is fixed to the side of the movable chamber 2. When the movable chamber 2 is opened, the buffer plate 16 compresses the rubber buffer strip 11, causing it to deform under pressure. The L-shaped strips 10 form mounting grooves for the rubber buffer strip 11, which stably fixes the rubber buffer strip 11 to the side of the top strip 4, preventing it from shifting or falling off when compressed by the buffer plate 16, ensuring that the buffering effect is accurately applied to the collision point. When the movable chamber 2 is fully opened, the buffer plate 16 actively compresses the rubber buffer strip 11, which slowly releases the collision energy through elastic deformation, smoothly offsetting the sliding inertia of the movable chamber 2 and preventing the movable chamber 2 from directly impacting the top strip 4 and causing damage.

[0024] like Figure 3 As shown, in this embodiment, the buffer assembly 15 also includes a connecting plate 14 fixed to the top of the movable chamber 2. Two L-shaped strips 12 are fixed to the side of the connecting plate 14 near the top bar 4. A rubber buffer strip 13 is engaged between the two L-shaped strips 12. When the movable chamber 2 is closed, the connecting plate 14 causes the rubber buffer strip 13 to fit against the side of the top bar 4. The rubber buffer strip 13 deforms under pressure. The connecting plate 14 provides an installation carrier for the L-shaped strips 12 and the rubber buffer strip 13, allowing the buffer assembly 15 to move synchronously with the movable chamber 2, ensuring the smooth operation of the chamber. When the movable cabin 2 is closed, the buffer assembly 15 can accurately align with the top bar 4. The L-shaped bar 2 12 is fixed to the rubber buffer bar 2 13 by snap-fit, preventing it from shifting under pressure and ensuring buffer stability. When the movable cabin 2 is closed in place, the rubber buffer bar 2 13 first contacts the side of the top bar 4 and deforms to absorb the impact force during the closing process, preventing the movable cabin 2 from directly hitting the inner wall of the fixed cabin 1. At the same time, it works with the rubber buffer bar 1 11 to achieve full-process buffering from opening to closing, further protecting the cabin structure, reducing collision damage, and ensuring that the opening and closing process of the movable cabin 2 is smooth and safe.

[0025] like Figure 3As shown in this embodiment, both the ends of rubber buffer strip 11 and rubber buffer strip 2 13 are provided with through grooves. The through grooves can provide a larger deformation space for rubber buffer strip 11 and rubber buffer strip 2 13. When rubber buffer strip 11 and rubber buffer strip 2 13 are compressed, the through groove area can further release the deformation stress through contraction, so that the deformation degree of rubber buffer strip 11 and rubber buffer strip 2 13 is greater and the buffer stroke is longer, thereby absorbing the impact force more fully and improving the buffering effect.

[0026] like Figure 3 As shown in this embodiment, the top strip 4 has a bent portion 7 on its side. The bent portion 7 is fixed to the side of the fixed compartment 1. The bent portion 7 can significantly increase the contact area between the top strip 4 and the fixed compartment 1, so that the top strip 4 is connected to the fixed compartment 1 through a dual connection method of top fixing and side fixing. Compared with a single fixing method, it is more stable and avoids the top strip 4 from loosening or deforming due to long-term bearing of the tension of the inflatable sealing strip 8 or the impact of the buffer assembly 15. At the same time, the bent portion 7 can also enhance the structural rigidity of the top strip 4 itself, prevent the top strip 4 from bending when under force, and ensure that it provides a stable installation reference for the sealing mechanism 3 and the buffer assembly 15, thus ensuring the structural stability and functional reliability of the entire expansion compartment.

[0027] Working principle: The movable compartment 2 is opened according to the usage requirements, and the movable compartment 2 slides open along the inner wall of the fixed compartment 1 to expand the usable space. During the opening process of the movable compartment 2, the buffer plate 16 on the side of the movable compartment 2 will gradually approach the rubber buffer strip 11 on the side of the top bar 4. Finally, the buffer plate 16 contacts and squeezes the rubber buffer strip 11 that is engaged between the two L-shaped bars 10. After being compressed, the rubber buffer strip 11 undergoes elastic deformation, which absorbs the impact force when the movable compartment 2 is opened, and avoids damage to the connection between the movable compartment 2 and the fixed compartment 1 due to excessive impact force. At the same time, the L-shaped bars 10 can fix the rubber buffer strip 11 to prevent it from shifting during the compression process and ensure stable buffering effect. After the movable chamber 2 is opened, if the application site has high requirements for sealing, air can be injected into the inflatable sealing strip 8 through the air inflator 9 on the outer wall of the inflatable sealing strip 8. Connect the air pipe to the air inflator 9 and use an air pump to inflate the inflatable sealing strip 8. Under the action of air pressure, the inflatable sealing strip 8 gradually expands, and its inner wavy sealing surface will tightly fit the outer wall of the movable chamber 2, thereby filling the gap between the fixed chamber 1 and the movable chamber 2, greatly improving the sealing between the two. During this process, the protrusions on the side of the extension 6 and the inner wall of the C-shaped strip 5 are stuck in the recesses on the side wall of the inflatable sealing strip 8, which can effectively prevent the inflatable sealing strip 8 from shifting or falling off when it expands, ensuring the stability of the sealing structure. The top bar 4 further increases the contact area with the fixed chamber 1 through the bending part 7, thereby improving the fixing stability of the top bar 4; When it is necessary to close the movable chamber 2, first press the valve core inside the inflation connector 9 to release the air from the inflation sealing strip 8. After the air is released, the inflation sealing strip 8 returns to its uninflated state under its own elastic force. Then close the movable chamber 2, allowing it to slide in the opposite direction along the inner wall of the fixed chamber 1 and reset. During the closing process of the movable chamber 2, the rubber buffer strip 13 on the top connecting plate 14 of the movable chamber 2 will gradually approach the side of the top strip 4. Finally, the rubber buffer strip 13 contacts the side of the top strip 4 and deforms under pressure. The rubber buffer strip 13 absorbs the impact force when the movable chamber 2 closes through deformation, protecting the connection position between the movable chamber 2 and the fixed chamber 1 again and avoiding collision damage. The L-shaped strip 12 fixes the rubber buffer strip 13, preventing it from shifting during the pressure process. In addition, the through grooves opened at the ends of the rubber buffer strip 11 and the rubber buffer strip 13 provide more space for their deformation, enhance the buffering capacity, and ensure that the opening and closing process of the movable chamber 2 is smooth and safe.

[0028] The above description is only a preferred embodiment of the present utility model. It should be noted that for those skilled in the art, several improvements and modifications can be made without departing from the principle of the present utility model, and these improvements and modifications should also be considered within the protection scope of the present utility model.
