Description

Technical Field

[0001] This utility model relates to the field of air pressure balance chamber technology, and in particular to high-altitude air pressure balance chamber. Background Technology

[0002] As a device that can simulate the atmospheric pressure environment of high altitudes, the high-altitude barometric altimeter has a wide range of applications in medical rehabilitation, sports training, and scientific research. In medical rehabilitation, it can help patients with altitude sickness alleviate symptoms and promote physical recovery. In sports training, athletes can conduct high-altitude acclimatization training inside the chamber to improve their athletic performance. Researchers can also use it to conduct research on the physiological effects of the high-altitude environment on the human body. However, to ensure the effective realization of its functions and the safety of its use, the structural design and performance optimization of the altimeter are crucial.

[0003] Currently, the existing high-altitude pressure equalization chambers on the market come in various forms in terms of mechanical structure and technical principle. Some adopt traditional air pressure regulation systems, which control the changes in air pressure inside the chamber through a combination of compressors and valves. In terms of the design of the chamber door, some use simple locking structures to fix the door to prevent air pressure leakage inside the chamber. The ventilation system mostly uses ordinary fans and ventilation ducts, and the ventilation volume is controlled by adjusting the fan speed. Although these technologies can meet the basic usage requirements to a certain extent, there is still room for improvement in terms of stability, safety and ease of operation.

[0004] However, existing high-altitude pressure balancing chambers have a serious problem in practical use: when the pressure difference between the inside and outside of the chamber is large, the traditional door locking method cannot withstand the enormous pressure. Due to the lack of an effective pressure buffer and locking mechanism, the door is prone to accidentally opening under pressure. This not only leads to a rapid imbalance of air pressure inside the chamber, affecting the normal operation of the equipment, but also causes serious damage to the personnel and equipment inside the chamber. Frequent pressure imbalances and equipment damage will also greatly shorten the service life of the device, increase the cost of use and the difficulty of maintenance. Therefore, the high-altitude pressure balancing chamber is proposed to solve the above problems. Utility Model Content

[0005] To overcome the above shortcomings, this utility model provides a high-altitude air pressure balance chamber, which aims to improve the problem in the prior art where the large internal and external pressures cause damage to personnel and equipment when the protective door is opened.

[0006] To achieve the above objectives, the present invention adopts the following technical solution:

[0007] A high-altitude barometric pressure balancing chamber includes a pressure balancing chamber, an observation window inside the pressure balancing chamber, a control panel inside the pressure balancing chamber, a protective door rotatably connected to the outer wall of the pressure balancing chamber, a sofa inside the pressure balancing chamber, a locking assembly inside the pressure balancing chamber, and a sealing assembly on the outer wall of the pressure balancing chamber.

[0008] The locking assembly includes a locking block and a locking groove inside the protective door. The outer wall of the locking block is slidably connected to the inside of the locking groove. A lifting block is fixedly connected to the bottom of the locking block. A hydraulic rod is fixedly connected inside the balance chamber.

Sliding columns are fixedly connected to both sides of the moving block. The outer walls of the sliding columns are slidably connected to the inside of the lifting groove.

[0009] As a further description of the above technical solution:

[0010] The sealing assembly includes a sealing plate, which is disposed on the outer wall of the balance chamber.

[0023] This utility model has the following beneficial effects:

[0024] 1. In this utility model, the lifting block achieves its lifting function by activating the hydraulic rod through a sensor. When the hydraulic rod is activated, the moving block and the sliding columns on both sides are driven by the hydraulic rod and cooperate with the lifting groove to limit the sliding, thereby realizing the sliding of the locking block inside the groove and locking the protective door. This solves the problem that the opening caused by large internal and external pressure will damage personnel and equipment, and improves the service life of the device.

[0025] 2. In this utility model, the sealing plate achieves its rotation function by activating the electric push rod. When the electric push rod is activated, the gear and rack are driven by the electric push rod and move in the groove in conjunction with the limiting post, thereby realizing the opening and closing of the sealing plate. This allows for convenient opening and closing of the ventilation opening and facilitates its adjustment. It solves the problem of not being able to conveniently open and close the heat dissipation holes and improves the convenience of opening and closing the ventilation opening of the device.

[0033] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0034] Reference Figure 1 - Figure 3 This utility model provides an embodiment of a high-altitude pressure balancing chamber, comprising a balancing chamber 1, an observation window 2 inside the balancing chamber 1, the observation window 2 being made of multi-layered thickened tempered glass, possessing good transparency and pressure resistance. Users can clearly observe the situation outside the chamber through it, while also withstanding a large pressure difference between the inside and outside of the chamber, ensuring safety. A control screen 3 is located inside the balancing chamber 1; the control screen 3 is an intelligent terminal integrating multiple functions, its screen using a high-definition LCD display, with a simple and intuitive operating interface, facilitating precise control of parameters such as air pressure, temperature, and oxygen content within the balancing chamber 1. A protective door 4 is rotatably connected to the outer wall of the balancing chamber 1. A sofa 5 is installed inside the balancing chamber 1. A locking component is installed inside the balancing chamber 1, and a sealing component is installed on the outer wall of the balancing chamber 1.

[0035] The locking assembly includes a locking block 9 and a locking groove 8 inside the protective door 4. The outer wall of the locking block 9 is slidably connected to the inside of the locking groove 8. A lifting block 7 is fixedly connected to the bottom of the locking block 9. A hydraulic rod 6 is fixedly connected inside the balance chamber 1. A moving block 11 is fixedly connected to the output end of the hydraulic rod 6. A slide rail 10 is fixedly connected inside the balance chamber 1. The slide rail 10 is made of high-strength carbon steel and its surface is finely polished to ensure the smoothness of the moving block 11 when it slides on it. The moving block 11 is slidably connected to the outer wall of the slide rail 10. A lifting groove 25 is opened inside the lifting block 7. Sliding columns 12 are fixedly connected to both sides of the moving block 11. The outer wall of the sliding column 12 is slidably connected to the inside of the lifting groove 25.

[0036] Specifically, safety is paramount when exercising inside the high-altitude pressure balance chamber 1. When the pressure difference between the inside and outside of the chamber is significant, the sensors installed inside will play a crucial role. When the pressure difference reaches a dangerous threshold, the sensors will quickly activate the hydraulic rod 6. The hydraulic rod 6 will drive the moving block 11 to slide smoothly on the outer wall of the slide rail 10. Since the moving block 11 is connected to the sliding columns 12 on both sides, the sliding of the moving block 11 will cause the sliding columns 12 on both sides to move synchronously. The sliding columns 12 are located inside the lifting groove 25, and their translational movement will further push the lifting block 7 to slide inside the protective door 4. As the lifting block 7 moves, it will push the locking block 9 into the locking groove 8, thereby achieving a firm lock on the control panel 3. This can effectively prevent the door from opening accidentally due to pressure difference and avoid safety accidents. At the same time, the locking method of the locking block 9 avoids the pressure being directly applied to the outer wall of the hydraulic rod 6 when locking directly using the hydraulic rod 6, thus effectively reducing the risk of damage to the hydraulic rod 6 and extending the service life of the equipment.

[0037] Reference Figure 4 and Figure 5 The sealing assembly includes a sealing plate 17, which is disposed on the outer wall of the balance chamber 1. A protective shell 13 is fixedly connected to the outer wall of the balance chamber 1. The protective shell 13 is made of sturdy aluminum alloy and has been anodized, which not only makes it aesthetically pleasing but also effectively prevents oxidation and corrosion. It mainly protects the internal sealing assembly from external physical damage and the effects of harsh environments. An electric push rod 24 is fixedly connected to the outer wall of the balance chamber 1. A rack 23 is fixedly connected to the output end of the electric push rod 24. A limit post 22 is fixedly connected to one side of the sealing plate 17, and a limit post 21 is fixedly connected to the other side of the sealing plate 17. A fixed disc is fixedly connected to the outer wall of the balance chamber 1. 19. A ventilation opening 20 is provided inside the fixed disc 19. The ventilation opening 20 is circular and the edges are chamfered to reduce the resistance when the gas flows. A limiting groove 18 is provided inside the fixed disc 19. The outer wall of the limiting post 21 is slidably connected to the limiting groove 18. A turntable 14 is rotatably connected to the outer wall of the fixed disc 19. A toothed ring 16 is fixedly connected to the outer wall of the turntable 14. The toothed ring 16 meshes with the rack 23. A limiting groove 15 is provided inside the turntable 14. The outer wall of the limiting post 22 is slidably connected to the limiting groove 15. Both the limiting post 21 and the limiting post 22 are made of stainless steel and the surface is polished to reduce the friction when sliding.

[0038] Specifically, during the operation of the high-altitude pressure balancing chamber 1, when it is necessary to maintain a specific air pressure and gas environment inside the chamber, the electric push rod 24 can be activated. After the electric push rod 24 is activated, it drives the rack 23 to move smoothly. Since the rack 23 and the gear ring 16 mesh with each other, the movement of the rack 23 will cause the gear ring 16 to start rotating. When the gear ring 16 rotates, the turntable 14 connected to it will rotate synchronously on the outer wall of the fixed disc 19. The turntable 14 has a limiting groove 15 inside. As the turntable 14 rotates, the limiting groove 15 also moves, thereby pushing the second limiting post 22 to produce displacement. At the same time, the first limiting post 21 on the other side will slide inside the limiting groove 18, and the sealing plate 17 will be driven to move, closing the vent 20, which can effectively maintain the air pressure and gas environment inside the balancing chamber 1 and ensure its stable operation.

[0039] Working principle: When exercising in the balance chamber 1, if there is a large pressure difference between the inside and outside, the hydraulic rod 6 is activated by the internal sensor. Then, the hydraulic rod 6 drives the moving block 11 to slide on the outer wall of the slide rail 10, and drives the sliding columns 12 on both sides to move horizontally. Because of its sliding inside the lifting groove 25, it pushes the lifting block 7 to slide inside the protective door 4, thereby pushing the locking block 9 into the locking groove 8 to lock the control panel 3. This prevents the door from being opened accidentally due to air pressure difference, which could cause a safety accident. Furthermore, the locking block 9 locks the door, avoiding the problem of directly applying pressure to the outer wall of the hydraulic rod 6 when locking it directly, which could easily damage the hydraulic rod 6.

[0040] In addition, when the balance chamber 1 needs to maintain a specific air pressure and gas environment, the electric push rod 24 can be activated. The electric push rod 24 drives the rack 23 to move, which in turn drives the meshing gear ring 16 to rotate. The gear ring 16 drives the turntable 14 to rotate on the outer wall of the fixed disc 19, and drives the internal limiting groove 15 to move, which in turn drives the limiting post 22 to move. At the same time, the limiting post 21 on the other side slides inside the limiting groove 18, which drives the sealing plate 17 to move, close the vent 20, and maintain the internal air pressure and gas.

[0041] Finally, it should be noted that the above description is only a preferred embodiment of the present utility model and is not intended to limit the present utility model. Although the present utility model has been described in detail with reference to the foregoing embodiments, those skilled in the art can still modify the technical solutions described in the foregoing embodiments or make equivalent substitutions for some of the technical features. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of the present utility model should be included within the protection scope of the present utility model.
