Description

Technical Field

[0001] This utility model relates to the field of high-pressure equipment technology, and more specifically, to a self-opening cabin door locking device for a hyperbaric oxygen chamber. Background Technology

[0002] Traditional hyperbaric oxygen chamber door locking mechanisms typically employ manual bolts or mechanical levers, relying on operator adjustment. This leads to uneven locking force and insufficient sealing, increasing the risk of gas leakage under high pressure and compromising treatment safety. Furthermore, these mechanisms may fail to lock properly in the event of a power outage or system malfunction, posing a safety hazard. Additionally, traditional sealing structures are prone to wear under prolonged high-pressure cycling, resulting in decreased airtightness. Therefore, a self-opening locking device with automatic locking force adjustment, high reliability, and rapid response is needed to improve the safety and automation level of hyperbaric oxygen chambers.

[0003] A search revealed that Chinese patent CN 220451612 U discloses a "self-opening chamber door locking device for a hyperbaric oxygen chamber," which includes a chamber body with a door opening. A door panel is hinged to the front side of the chamber body corresponding to the door opening. A first control box is installed on the left side of the door panel corresponding to the front side of the chamber body. Guide rails are installed at heights near the top and bottom of the rear inner wall of the first control box, and racks are movably installed on the guide rails. Inserts are fixedly installed on the right side of the racks, and slots are opened on the left side of the door panel corresponding to the inserts. The racks are connected to a drive mechanism. A control mechanism is installed on the right inner wall of the first control box. However, the following defects still exist: (1) The locking mechanism of the door of the traditional hyperbaric oxygen chamber is mostly a manual bolt or mechanical lever locking method, which relies on the operator to adjust manually. This results in problems such as uneven locking force and insufficient sealing. Under high pressure, gas leakage is likely to occur, affecting the safety of treatment. However, in the event of a power outage or system failure, the door may not be able to lock securely, posing a safety hazard. Therefore, a self-opening door locking device for hyperbaric oxygen chambers is proposed. Utility Model Content

[0004] The purpose of this utility model is to address the existing problems where the locking mechanism of the door of a traditional hyperbaric oxygen chamber mostly adopts manual bolts or mechanical lever locking methods, which rely on manual adjustment by the operator. These methods have problems such as uneven locking force and insufficient sealing, and are prone to gas leakage under high pressure, affecting treatment safety.

[0005] To achieve the above-mentioned objectives, this utility model provides the following technical solution: The present invention is as follows: a self-opening chamber door locking device for a hyperbaric oxygen chamber, including a support base, a chamber body fixedly connected to the top of the support base, a door assembly fixedly connected to the circumferential surface of the chamber body, and a locking device provided on the inner wall of the chamber body; The locking device includes a door, which is fixedly connected to the side of the door assembly. A motor is provided on the front of the door, and a rotating rod is fixedly connected to the end of the output shaft of the motor. A lock chamber is fixedly connected to the inner wall of the cabin. An action groove is provided on the inner wall of the lock chamber, and a large rectangular groove is provided on the outer surface of the action groove. A gear is fixedly connected to the circumferential surface of the rotating rod.

[0006] As a preferred technical solution of this utility model, a support block is fixedly connected to the left inner wall of the lock chamber, a toothed block is fixedly connected to the side of the support block, a limit block is fixedly connected to the inner wall of the lock chamber, and a rectangular block is fixedly connected to the side of the rotating rod. The function of the limit block is to limit the movement of the gear when the rotating rod rotates, thereby achieving intelligent locking.

[0007] As a preferred technical solution of this utility model, there are two support blocks, which are arranged in a circumferential array on the circumferential surface of the tooth block. The limiting block is located on the movement trajectory of the gear. The function of the support block is to support the tooth block, so as to facilitate the rotation of the gear and thus lock the door.

[0008] As a preferred technical solution of this utility model, the inner wall of the cabin is provided with an auxiliary device, the auxiliary device including a pulley, the pulley being fixedly connected to the circumferential surface of the rotating rod, the circumferential surface of the pulley being driven by a belt, the side of the machine door being rotatably connected to a rotating rod, the circumferential surface of the rotating rod being fixedly connected to a rotating sleeve, the inner wall of the lock chamber being fixedly connected to a rubber sealing ring, and the front of the machine door being fixedly connected to a handle. The function of the rubber sealing ring is to seal the lock chamber when the sealing cover is closed.

[0009] As a preferred technical solution of this utility model, a sealing cover is provided on the front of the lock chamber, and a through opening is provided on the front of the sealing cover. The through opening is used to allow the rotating rod to enter the interior of the lock chamber through the through opening when the door is closed.

[0010] As a preferred technical solution of this utility model, the rotating rod rotates through the front of the sealing cover, the rotating rod cooperates with the through opening, and the rubber sealing ring cooperates with the sealing cover. The function of the rotating rod is that in the event of a power outage, the operator can rotate the rotating sleeve to drive the rotating rod to rotate, and the rotating rod will be driven to rotate through the belt drive, thereby opening the locking structure.

[0011] As a preferred technical solution of this utility model, the function groove is located inside the large rectangular groove, and a rectangular block is rotatably connected to the inner wall of the function groove. The gear and the gear block mesh with each other. The function of the function groove is to lock the rectangular block into the function groove by rotating it when the rectangular block enters the inner wall of the large rectangular groove.

[0012] Compared with the prior art, the beneficial effects of this utility model are as follows: 1. By using a locking device, when the rectangular block fixed to the side of the rotating rod is rotated to a vertical position on the inner wall of the large rectangular groove, the gear contacts the limit block, causing the rotating rod to stop rotating under the action of the gear, thus achieving a locking effect. This avoids problems such as uneven locking force and insufficient sealing caused by manual locking, and also improves work efficiency. 2. By using an auxiliary device, the rotating rod is rotated, and the belt drive drives the rotating rod to rotate, causing the locking device to move again. This ensures that even in the event of a power outage, the operator can still open the machine door by rotating the rotating sleeve or continue to lock it, preventing the machine door 1 from being unable to be opened after a power outage.

[0019] like Figure 1 , Figure 2 , Figure 3 , Figure 5 As shown in the figure, this embodiment proposes a self-opening chamber door locking device for a hyperbaric oxygen chamber, including a support base 1, a chamber body 2 fixedly connected to the top of the support base 1, a door assembly 3 fixedly connected to the circumferential surface of the chamber body 2, and a locking device 4 provided on the inner wall of the chamber body 2. The locking device 4 includes a door 41, which is fixedly connected to the side of the door assembly 3. A motor 42 is provided on the front of the door 41. A rotating rod 43 is fixedly connected to the end of the output shaft of the motor 42. A lock chamber 44 is fixedly connected to the inner wall of the cabin 2. An action groove 45 is provided on the inner wall of the lock chamber 44. A large rectangular groove 46 is provided on the outer surface of the action groove 45. A gear 47 is fixedly connected to the circumferential surface of the rotating rod 43.

[0020] like Figure 2 As shown, in a preferred embodiment, based on the above method, a support block 48 is fixedly connected to the left inner wall of the lock chamber 44, a toothed block 49 is fixedly connected to the side of the support block 48, a limit block 410 is fixedly connected to the inner wall of the lock chamber 44, and a rectangular block 411 is fixedly connected to the side of the rotating rod 43. The function of the limit block 410 is to limit the movement of the gear 47 when the rotating rod 43 rotates, thereby achieving intelligent locking.

[0021] like Figure 3As shown, in a preferred embodiment, based on the above method, there are two support blocks 48, which are arranged in a circumferential array on the circumferential surface of the tooth block 49. The limiting block 410 is located on the movement trajectory of the gear 47. The function of the support blocks 48 is to support the tooth block 49, so as to facilitate the rotation of the gear and thus lock the door 41.

[0022] like Figure 4 , Figure 5 , Figure 6 As shown, in a preferred embodiment, based on the above method, an auxiliary device 5 is further provided on the inner wall of the cabin 2. The auxiliary device 5 includes a pulley 51, which is fixedly connected to the circumferential surface of the rotating rod 43. A belt 52 is drivenly connected to the circumferential surface of the pulley 51. A rotating rod 53 is rotatably passed through the side of the machine door 41. A rotating sleeve 54 is fixedly connected to the circumferential surface of the rotating rod 53. A rubber sealing ring 55 is fixedly connected to the inner wall of the lock chamber 44. A handle 56 is fixedly connected to the front of the machine door 41. The function of the rubber sealing ring 55 is to seal the lock chamber 44 when the sealing cover 57 is closed.

[0023] like Figure 4 As shown, in a preferred embodiment, based on the above method, a sealing cover 57 is further provided on the front of the lock chamber 44, and a through opening 58 is provided on the front of the sealing cover 57. The function of the through opening 58 is to allow the rotating rod 43 to enter the interior of the lock chamber 44 through the through opening 58 when the door 41 is closed.

[0024] like Figure 5 As shown, in a preferred embodiment, based on the above method, the rotating rod 53 rotates through the front of the sealing cover 57, the rotating rod 53 cooperates with the through opening 58, and the rubber sealing ring 55 cooperates with the sealing cover 57. The function of the rotating rod 53 is that in the event of a power outage, the operator can rotate the rotating sleeve 54 to drive the rotating rod 53 to rotate, and drive the rotating rod 43 to rotate through the belt drive, thereby opening the locking structure.

[0025] like Figure 1 , Figure 2 , Figure 4 , Figure 5 As shown, in a preferred embodiment, based on the above method, the action groove 45 is further located inside the large rectangular groove 46, and a rectangular block 411 is rotatably connected to the inner wall of the action groove 45. The gear 47 and the tooth block 49 mesh with each other. The function of the action groove 45 is to lock the rectangular block 411 into the inner wall of the large rectangular groove 46 by rotating it.

[0026] Specifically, when using this self-opening door locking device for hyperbaric oxygen chambers: the operator needs to first close the door 41. At this time, the rectangular block 411 is in a balanced state. As the rotating rod 43 enters the action groove 45, the operator then starts the external power supply, forcing the motor 42 to start, causing the rotating rod 43 to rotate under force. The gear 47 fixed on the circumferential surface of the rotating rod 43 rotates. Through gear meshing, the gear 47 rotates and meshes on the circumferential surface of the tooth block 49. When the rectangular block 411 fixed on the side of the rotating rod 43 is in a vertical state on the inner wall of the large rectangular groove 46 through rotation, the gear 47 contacts the limit block 410, causing the rotating rod 43 to stop rotating under the action of the gear 47, achieving the locking effect. This avoids problems such as uneven locking force and insufficient sealing caused by manual locking, and improves work efficiency.

[0027] The rotation of the rotating rod 43 causes the pulley 51 fixed on the circumference of the rotating rod 43 to rotate. The belt 52 drives another pulley 51 fixed on the circumference of the rotating rod 53 to rotate, causing the rotating rod 53 to rotate. In the event of a power outage, the operator can rotate the rotating sleeve 54 fixed on the circumference of the rotating rod 53 to rotate the rotating rod 53. The belt drive drives the rotating rod 43 to rotate, and the locking device 4 moves again. This ensures that even in the event of a power outage, the operator can still rotate the rotating sleeve 54 to open the machine door 41 or continue to lock it, preventing the machine door 41 from being unable to be opened after a power outage.

[0028] All technical features in this embodiment can be freely combined according to actual needs.

[0029] The above embodiments are preferred implementations of this utility model. In addition, this utility model can also be implemented in other ways. Any obvious substitutions without departing from the concept of this technical solution are within the protection scope of this utility model.
