Description
Technical Field
[0001] This application relates to the field of animal oxygen chambers, and particularly to a pneumatic interlock device for the door of an animal hyperbaric oxygen chamber. Background Art
[0002] An animal hyperbaric oxygen chamber is a medical device specifically designed for animals, mainly used to provide hyperbaric oxygen therapy. This treatment method can increase the dissolved oxygen in the blood, which has a positive effect on improving the anoxic symptoms of animals and promoting wound healing. The animal hyperbaric oxygen chamber can simulate a hyperbaric oxygen environment and is applicable to small and medium-sized animals such as dogs, monkeys, rabbits, rats, etc., and is widely used in emergency therapies or medical adjuvant therapies in small animal clinics.
[0003] The door design of the animal oxygen chamber is crucial for ensuring the safety and effectiveness of the treatment. The door design of the animal oxygen chamber needs to consider factors such as pressure resistance, safety, operation convenience, and transparency. The door structure of the traditional animal oxygen chamber includes a door body, a clamping shaft, and two connecting plates. One end of the door body is rotatably installed on the chamber body, and the two connecting plates are rotatably arranged on the chamber body and are located at one end of the door body away from its hinge structure. The two connecting plates are respectively located above and below the door body. The clamping shaft is vertically arranged, and both ends are respectively installed on the two connecting plates, and a handle is fixed on the clamping shaft. After the door body closes and seals the chamber body, hold the handle and rotate the clamping shaft, and clamp the clamping shaft on the door body to pressurize the door body and keep the door body closed continuously.
[0004] However, with the increase in the service life and the number of uses, the clamping structure between the clamping shaft and the door body will become loose, affecting its sealing effect. Utility Model Content
[0005] In order to improve the sealing effect of the door, this application provides a pneumatic interlock device for the door of an animal hyperbaric oxygen chamber, which has the advantages of convenient use and reliable sealing.
[0006] The pneumatic interlock device for the door of an animal hyperbaric oxygen chamber provided by this application adopts the following technical solution:
[0007] A pneumatic interlock device for the door of an animal hyperbaric oxygen chamber includes a pneumatic interlock seat and a quick clamp. The pneumatic interlock seat is fixed to the chamber body and is communicated with the inside of the hyperbaric oxygen chamber. The pneumatic interlock seat has a telescopic limiting end. The quick clamp is fixed to the chamber body and has a movable locking end. A locking seat is fixed on the door body, and the locking seat is clamped and matched with the locking end of the quick clamp. The limiting end extends out when the hyperbaric oxygen chamber is started and extends to the side of the locking end away from the chamber body.
[0008] By adopting the above technical solution, after locking the hatch door with a quick clamp, start the hyperbaric oxygen chamber. The limiting end extends and reaches to the side of the locking end away from the chamber body to limit the locking end, improving the stability of the door body closing. When the hyperbaric oxygen chamber is closed, the pressure inside the chamber decreases, and the plugging end automatically disengages from the locking hole. At this time, the door body can be normally rotated and opened. The locking of the limiting end is bound to the pressure inside the chamber, which is very convenient to use and does not require manual adjustment.
[0009] Optionally, the pneumatic interlock seat includes a seat body, a guide member, and a pneumatic lock core. The seat body is fixed to the door body, the guide member is installed on the seat body, the seat body is provided with a sliding cavity, the guide member is provided with a sliding hole, the sliding cavity is communicated with the sliding hole, one end of the pneumatic lock core is slidably arranged in the sliding cavity, and the other end slides through the sliding hole. The seat body is provided with a ventilation hole on the side away from the guide member of the sliding cavity, and the ventilation hole is communicated to the inside of the hyperbaric oxygen chamber.
[0010] By adopting the above technical solution, when a high air pressure is formed inside the hyperbaric oxygen chamber, the pneumatic lock core extends out of the sliding hole under the action of the internal and external pressure difference and reaches to one side of the locking end to limit the door body, improving the sealing effect.
[0011] Optionally, an air cavity is further provided in the seat body, the air cavity is communicated between the sliding cavity and the ventilation hole, and the connecting surface of the air cavity and the sliding cavity is larger than the cross section of the ventilation hole.
[0012] By adopting the above technical solution, when the air pressure inside the chamber increases, the gas accumulates in the air cavity, which can increase the force-bearing surface of the pneumatic lock core and make it more convenient for the pneumatic lock core to extend.
[0013] Optionally, the pneumatic lock core is in a T shape, and the end with a larger diameter of the pneumatic lock core slides in the sliding cavity.
[0014] By adopting the above technical solution, the T-shaped structure is simple and easy to process and can form an anti-disengagement effect to prevent the pneumatic lock core from disengaging from the seat body.
[0015] Optionally, a gas-accumulating groove is provided on the side of the pneumatic lock core close to the air cavity, and the gas-accumulating groove is used to increase the force-bearing surface of the pneumatic lock core.
[0016] By adopting the above technical solution, when the air pressure inside the chamber increases, the air flow flows into the gas-accumulating groove, further increasing the force-bearing surface of the pneumatic lock core and improving the locking effect of the pneumatic lock core.
[0017] Optionally, the gas-accumulating groove is formed by copying the shape inside the pneumatic lock core.
[0018] By adopting the above technical solution, the gas-accumulating groove with as large a size as possible can be formed by using the copying structure, thereby increasing the acting force on the pneumatic lock core.
[0019] Optionally, a first sealing ring is clamped between the seat body and the guide member.
[0020] By adopting the above technical solution, the first sealing ring forms a reliable seal between the seat body and the guide member, avoiding gas leakage and ensuring that the cabin remains in a high-pressure environment.
[0021] Optionally, a second sealing ring is clamped between the pneumatic lock core and the guide member.
[0022] By adopting the above technical solution, the second sealing ring forms a seal between the pneumatic lock core and the guide member, cooperating with the first sealing ring to form a complete sealing surface, which can effectively prevent gas leakage in the cabin.
[0023] Optionally, a limit seat is fixed on the door body, and a limit pin is slidably inserted through the limit seat. When the door body is closed and the clamping shaft is clamped to the door body, the locking block is located on the side of the limit pin away from the door body and abuts against the side wall of the limit pin.
[0024] By adopting the above technical solution, the limit pin further fixes the position of the clamping shaft by means of limiting the locking block, so as to improve the sealing effect of the cabin door.
[0025] In summary, the present application includes at least one of the following beneficial technical effects:
[0026] 1. After locking the cabin door with the quick clamp, start the hyperbaric oxygen chamber. The limiting end extends and reaches the side of the locking end away from the cabin body to limit the locking end, improving the stability of the door body closing; and when the hyperbaric oxygen chamber is closed, the pressure in the cabin decreases, and the plug-in end automatically disengages from the locking hole. At this time, the door body can be normally rotated and opened.

Detailed implementation manners
[0035] The following will further describe the present application in detail Figures 1-5 with reference to the accompanying drawings.
[0036] The embodiments of the present application disclose a pneumatic interlock device for the door of an animal hyperbaric oxygen chamber. Referring to Figure 1 and Figure 2 , it includes a pneumatic interlock seat 1 and a quick clamp 2. The quick clamp 2 is fixed to the chamber body of the hyperbaric oxygen chamber and has a movable locking end. A locking seat 3 that cooperates with the locking end is fixed on the door body 01. The locking end is engaged with the locking seat 3 to lock the door body 01 to the chamber body. The pneumatic interlock seat 1 is fixed to the chamber body and is used to lock the limiting end of the quick clamp 2 to further improve the stability of the closing of the door body 01.
[0037] Specifically, referring to Figure 2 and Figure 3 , the quick clamp 2 includes a clamp seat 21, a rotating body 22 and a locking member 24. The clamp seat 21 is fixed to the side wall of the chamber body. The rotating body 22 is hinged to the clamp seat 21, and a rotating shaft 23 is passed through the rotating body 22. The rotating shaft 23 is rotatably matched with the rotating body 22. The locking member 24 has a U-shaped structure, and the two ends of the U-shaped opening side are located on both sides of the rotating body 22 and are respectively fixed to both ends of the rotating shaft 23. When the rotating body 22 rotates on the clamp seat 21, it drives the locking member 24 to move in a direction close to or away from the locking seat 3 to cooperate to complete locking and unlocking.
[0038] Among them, a locking groove is formed on the locking seat 3, and the notch of the locking groove faces away from the side of the quick clamp 2. The U-shaped end of the locking member 24 forms the locking end of the quick clamp 2. When locking is required, rotate the rotating body 22 to drive the locking member 24 to move, and make the U-shaped end of the locking member 24 snap into the locking groove. Rotating the rotating body 22 away from the locking seat 3 can tightly fasten the locking member 24 in the locking groove. When unlocking, rotate the rotating body 22 towards the locking seat 3, and the U-shaped end of the locking member 24 can be disengaged from the locking groove to complete the unlocking.
[0039] Further, referring to Figure 2 and Figure 3 , the quick clamp 2 further includes a self-locking member 28. An installation shaft 25 is fixed on the rotating body 22. The self-locking member 28 is rotatably arranged on the installation shaft 25. At the same time, a second locking groove 211 is formed on the clamp seat 21. A self-locking protrusion 281 is formed on the side of the self-locking member 28 close to the second locking groove 211. The self-locking protrusion 281 and the second locking groove 211 are in snap-fit. After rotating the rotating body 22 to lock the locking member 24 with the locking seat 3, rotate the self-locking member 28 and make the self-locking protrusion 281 snap into the second locking groove 211 to lock the position of the rotating body 22 and improve the locking effect on the door body 01.
[0040] Further, referring to Figure 2 and Figure 3 , a torsion spring 26 is sleeved on the installation shaft 25. Two ends of the torsion spring 26 respectively abut against the self-locking member 28 and the rotating shaft 23, and make the self-locking member 28 rotate towards the second locking groove 211. The torsion spring 26 ensures that the self-locking member 28 remains locked, further improving the stability of the locking effect and thus improving the locking effect on the door body 01.
[0041] Further, referring to Figure 4 and Figure 5 , the pneumatic interlock seat 1 has a telescopic limiting end. When the hyperbaric oxygen chamber is started and a relatively high air pressure is formed inside, the limiting end extends and is located on the side of the locking member 24 away from the cabin body, and retracts when the hyperbaric oxygen chamber is closed. When the quick clamp 2 is accidentally loosened, the limiting end forms a limit on the locking member 24 to prevent the locking member 24 from disengaging from the first locking groove 31, so as to form multiple locks, greatly improving the stability when the door body 01 is closed. And the pneumatic interlock seat 1 works automatically following the pressure inside the hyperbaric oxygen chamber without manual adjustment, which is convenient to use.
[0042] Further, referring to Figure 4 and Figure 5, the pneumatic interlock seat 1 includes a seat body 11, a guide member 12, and a pneumatic lock core 13. The seat body 11 is fixed to the outer side wall of the cabin, and a cylindrical sliding cavity 14 is formed inside it. The guide member 12 is screwed to the top of the seat body 11 and is provided with a sliding hole 15 through it. The sliding cavity 14 is communicated with the sliding hole 15, and their axes are vertical. The diameter of the sliding cavity 14 is larger than that of the sliding hole 15. The pneumatic lock core 13 is formed by connecting two cylinders with different diameters, and the overall structure is T-shaped. The smaller-diameter end of the pneumatic lock core 13 slides through the sliding hole 15 and slides inside the sliding hole 15 as the insertion end of the pneumatic interlock seat 1. The larger-diameter end slides through the sliding cavity 14. At the same time, a ventilation hole 16 is communicatedly opened on one side of the sliding cavity 14 away from the sliding hole 15 to communicate the sliding cavity 14 with the inside of the hyperbaric oxygen chamber.
[0043] In the normal state, the pneumatic lock core 13 contracts inside the seat body 11 and the guide member 12 under the action of gravity. When the door body 01 is closed and the air pressure is formed inside the hyperbaric oxygen chamber, the internal and external pressure difference forms a force, pushing the pneumatic lock core 13 to move upward. The smaller-diameter end of the pneumatic lock core 13 extends out of the sliding hole 15 and reaches one side of the locking member to lock the locking member.
[0044] Furthermore, referring to Figure 4 and Figure 5 , an air cavity 17 is also formed inside the seat body 11. The air cavity 17 is located on the side of the sliding cavity 14 away from the sliding hole 15, and the cross-section of the air cavity 17 is smaller than that of the sliding cavity 14. The ventilation hole 16, the air cavity 17, and the sliding cavity 14 are communicated in sequence, and the communicating surface of the air cavity 17 and the sliding cavity 14 is larger than the cross-section of the ventilation hole 16. When the air pressure inside the cabin increases, the gas accumulates in the air cavity 17, which can increase the force-bearing surface of the pneumatic lock core 13 and make it easier for the pneumatic lock core 13 to extend.
[0045] Furthermore, referring to Figure 4 and Figure 5 , a gas-accumulating groove 18 is formed on one side of the pneumatic lock core 13 close to the air cavity 17. The gas-accumulating groove 18 is formed by connecting two cylindrical holes with different diameters, and the overall structure is T-shaped. The smaller-diameter section of the gas-accumulating groove 18 is formed inside the smaller-diameter section of the pneumatic lock core 13. Correspondingly, the larger-diameter section of the gas-accumulating groove 18 is formed inside the larger-diameter section of the pneumatic lock core 13, that is, the gas-accumulating groove 18 is formed in imitation of the shape inside the pneumatic lock core 13. When the air pressure inside the cabin increases, the air flow flows into the gas-accumulating groove 18, further increasing the force-bearing surface of the pneumatic lock core 13 and improving the locking effect of the pneumatic lock core 13.
[0046] Referring to Figure 5, a first sealing ring 4 is clamped between the seat body 11 and the guide member 12. As the guide member 12 is screwed into the seat body 11, the guide member 12 and the seat body 11 gradually clamp the first sealing ring 4, and a reliable sealing effect is formed between the two to prevent gas leakage and affect the high-pressure environment inside the cabin.
[0047] Meanwhile, a second sealing ring 5 is sleeved on a portion of the pneumatic lock core 13 with a smaller diameter, and the second sealing ring 5 abuts against a portion of the pneumatic lock core 13 with a larger diameter. When the pneumatic lock core 13 extends outward under the action of the internal air pressure, the pneumatic lock core 13 and the guide member 12 gradually clamp the second sealing ring 5 to prevent gas leakage.
[0048] Furthermore, referring to Figure 1 , locking screws 6 are passed through the door body 01, and one end of each locking screw 6 passes through the door body 01 and is screwed into the cabin body. In this embodiment, four locking screws 6 are provided and are evenly distributed on the door body 01. The locking screws 6 can further improve the tightness between the door body 01 and the cabin body, and thus improve the sealing performance.
[0049] The implementation principle of a pneumatic interlock device for an animal hyperbaric oxygen chamber door disclosed in an embodiment of the present application is as follows:
[0050] When the door body 01 is closed, air pressure is formed inside the hyperbaric oxygen chamber and pushes the pneumatic lock core 13 to move, so that the end of the pneumatic lock core 13 extends to one side of the locking member 24. The end of the pneumatic lock core 13 limits the locking member 24 to prevent the locking member 24 from disengaging from the first locking groove 31, and improves the stability of the closure of the door body 01.
[0051] The above are all preferred embodiments of the present application, and the protection scope of the present application is not limited thereby. Therefore, all equivalent changes made according to the structure, shape, and principle of the present application should be covered within the protection scope of the present application.
