Technical Field

[0001] The utility model relates to the technical field of sterilization cabinets, and particularly relates to an automatic door opening and safety interlocking mechanism for a sterilization cabinet. Background Art

[0002] Due to the structural dimensions, the transmission mechanism of a small steam sterilization cabinet cannot be integrated on the door body, or it is opened or closed manually. This manual door opening method cannot meet the automation requirements, increases the labor intensity of workers to a certain extent, and more importantly, cannot meet the GMP requirements for the sterilization environment.

[0003] An automatic sealing door of a sterilizer with the publication number of CN105582563B discloses a driving device capable of driving a door body to rotate, including a sealing device arranged between the door body and the main body; the sealing device includes locking teeth I and locking teeth II, and protrusions and grooves are sequentially arranged along the length direction of the locking teeth I and the locking teeth II; it includes a lifting device capable of driving the door body to lift. When the door body rotates and closes, the lifting device first lifts the door body, so that the protrusions and grooves on the locking teeth I and the locking teeth II are engaged with each other, and then the lifting device drops the door body, so that the protrusions on the locking teeth I and the locking teeth II overlap, thereby locking and sealing the door body. Although it discloses a structure capable of realizing automatic door opening and closing, many components are exposed to the air, which is not conducive to cleaning. Content of the Utility Model

[0004] The technical problem to be solved by the utility model is: some structures of the sterilization cabinet are exposed to the air, which is not conducive to cleaning and not aesthetically pleasing.

[0005] To solve the above technical problems, the present invention adopts the following technical solutions:

[0006] First, provide an automatic door opening and safety interlocking mechanism for a sterilization cabinet, including a box body, a sterilization cabinet body, and a door panel. The sterilization cabinet body is installed in the box body. One side of the sterilization cabinet body is open, and a lifting shaft is installed at the opening. A door panel is rotatably installed on the lifting shaft. A power mechanism for driving the lifting shaft to reciprocate is arranged in the box body. An axle shoulder for supporting the door panel is arranged on the lifting shaft. A locking mechanism for preventing the door panel from opening is arranged on the sterilization cabinet body. The locking mechanism includes a C-shaped caliper. Several first clamping blocks are arranged at equal distances along the length direction of the caliper. Several second clamping blocks are installed at equal distances at the positions corresponding to the first clamping blocks on the door panel. The second clamping blocks can be engaged and matched between the first clamping blocks. A sealing component is arranged between the door panel and the sterilization cabinet body.

[0007] After the cabinet door is closed, the power mechanism drives the lifting shaft to move, so that the second clamping block on the cabinet door overlaps with the first clamping block, thereby achieving the effect of locking the cabinet door on the sterilization cabinet body.

[0008] Furthermore, the power mechanism includes a power member, an output end of which is connected to a lifting shaft and is used to drive the lifting shaft to move back and forth; the power member drives the lifting shaft to move back and forth to achieve locking and unlocking of the cabinet door.

[0009] Furthermore, the power part is a motor, a screw is connected to the output end of the motor, a limit plate is connected to the screw through a thread, and the lifting shaft is fixedly connected to the limit plate; the screw rotates under the action of the motor, and drives the limit plate to move up and down under the action of the thread, thereby realizing the movement of the lifting shaft.

[0010] Furthermore, an upper limit switch and a lower limit switch are arranged in the box body, and the limit plate is located between the upper limit switch and the lower limit switch; the setting of the upper and lower limit switches enables the limit plate to move back and forth within a certain range, thereby achieving the overlap and stagger of the first card block and the second card block.

[0011] Furthermore, the sealing assembly comprises a sealing ring, and compressed air is connected to the inside of the sealing ring; the expansion of the sealing ring makes the sealing effect of the cabinet door better.

[0012] Furthermore, a connecting plate is rotatably installed at a position corresponding to the shaft shoulder on the lifting shaft, and the door panel is fixedly connected to the connecting plate; the shaft shoulder is used to push the connecting plate to move upward to ensure stable operation of the device.

[0013] Furthermore, a rolling bearing is provided between the shaft shoulder and the connecting plate; the rolling bearing reduces the friction between the connecting plate and the shaft shoulder, so that the connecting plate rotates more smoothly.

[0014] Furthermore, the connecting plate and the lifting shaft are rotationally connected via a hinge.

[0015] Furthermore, two calipers are symmetrically installed on the sterilization cabinet body at positions corresponding to the door panels; two C-shaped calipers are used to lock both sides of the cabinet door, so that the cabinet door is more evenly held, less likely to deform, and has a better use effect.

[0016] Furthermore, protective covers are provided on the box body at both ends of the lifting shaft; the protective covers are used to protect the two ends of the lifting shaft, making the overall device structure more reasonable, and at the same time, the requirements for the use environment are more extensive, and it can be applied to various situations.

[0017] The utility model has the following beneficial effects: The cooperation between the first clamping block and the second clamping block makes it more convenient to close and open the cabinet door. The separated structure ensures the cleanliness, sealing performance and safety interlock of the device. While the structure is compact, it is also convenient to clean, and the use effect is better. At the same time, the sealing effect of the sterilization cabinet is better by introducing air into the sealing ring, avoiding air leakage. The setting of the protective cover also makes the overall structure more complete and reasonable, and has more usage scenarios and a wider range of applications. BRIEF DESCRIPTION OF THE DRAWINGS

[0026] In order to better explain the present utility model for easy understanding, the following will make a detailed description of the present utility model through specific embodiments in conjunction with the drawings.

[0027] It should be noted that all the directional indications in the embodiments of the present utility model are only used to explain the relative positional relationship and movement conditions between components in a certain specific posture. If this specific posture changes, the directional indications will also change accordingly.

[0028] In addition, in the present utility model, descriptions such as "first", "second", etc. are only for descriptive purposes and should not be construed as indicating or implying their relative importance or implicitly specifying the quantity of the indicated technical features. Thus, features defined with "first" and "second" may explicitly or implicitly include at least one such feature. In the description of the present utility model, the meaning of "a plurality" is at least two, such as two, three, etc., unless otherwise specifically defined.

[0029] In the present utility model, unless otherwise clearly specified and defined, terms such as "connection" and "fixation" shall be understood in a broad sense. For example, "fixation" can be a fixed connection, a detachable connection, or integrated; it can be a mechanical connection or an electrical connection; it can be directly connected or indirectly connected through an intermediate medium, and it can be the internal communication of two components or the interaction relationship between two components, unless otherwise clearly defined. For those of ordinary skill in the art, the specific meanings of the above terms in the present utility model can be understood according to specific circumstances.

[0030] The present utility model provides an automatic door opening and safety interlock mechanism for a sterilization cabinet, as Figure 1 and Figure 2 shown, which includes a box body 10. A sterilization cabinet body 11 is installed inside the box body 10. The front side of the sterilization cabinet body 11 is open, and a cabinet door 12 is rotatably installed at the opening. Specifically, a lifting shaft 20 is installed at the opening edge of the sterilization cabinet body 11, and the cabinet door 12 is rotatably installed on the lifting shaft 20. Manually rotating the cabinet door 12 can achieve the opening and closing of the sterilization cabinet body 11. To improve the sealing performance of the sterilization cabinet body 11, a sealing ring is installed between the cabinet door 12 and the sterilization cabinet body 11. The sealing ring is hollow, and compressed air is communicated inside the sealing ring. When the cabinet door 12 is closed, air is introduced into the sealing ring, and the sealing ring expands to make its sealing effect better.

[0031] As Figure 3 and Figure 7 shown, to prevent the cabinet door 12 from opening by itself when it is closed, a C-shaped caliper 14 is installed on the sterilization cabinet body 11. When the cabinet door 12 is closed, the notch of the C-shaped caliper 14 faces the end of the cabinet door 12. A plurality of first blocks 15 are arranged at equal distances along the length direction of the C-shaped caliper 14. A second block is provided at the position of the cabinet door 12 corresponding to the first blocks 15. The second block can be engaged with the first blocks 15. When the cabinet door 12 is closed, the second block passes through the gap between the first blocks 15 and enters the C-shaped caliper 14.

[0032] Furthermore, in order to make the second clamping block and the first clamping block 15 play the role of locking the cabinet door 12, a power mechanism is installed on the lifting shaft 20, which can drive the lifting shaft 20 to move up and down. When the cabinet door 12 is closed, the lifting shaft 20 moves so that the second clamping block on the cabinet door 12 coincides with the first clamping block 15 on the C-shaped caliper 14, thereby locking the cabinet door 12 and preventing the cabinet door 12 from opening by itself. When the cabinet door 12 needs to be opened, the power mechanism drives the lifting shaft 20 to move in the opposite direction to stagger the second clamping block 15 and the second clamping block, so that the second clamping block can pass through the gap between the first clamping block 15, thereby opening the cabinet door 12. In order to improve the stability of the device, two calipers 14 are symmetrically installed at the positions corresponding to the door panels 12 on the sterilization cabinet body 11, and the cabinet door 12 is clamped from both sides, so that the safety performance is higher, and the cabinet door 12 is subjected to more uniform force, so that it is not easy to deform and has a longer service life.

[0033] like Figure 5 and Figure 6 As shown, the power mechanism includes a motor 21, and a screw 22 is installed at the output end of the motor 21. A limit plate 23 is installed on the screw 22 through a thread, and the lifting shaft 20 is passed through the lifting plate 23. When the motor 21 is working, it drives the screw 22 to rotate. Under the action of the thread, the rotation of the screw 22 drives the limit plate 23 to move, and the movement of the limit plate 23 drives the movement of the lifting shaft 20. In the process of locking and unlocking the cabinet door, the motor 21 can be realized by forward and reverse rotation.

[0034] Specifically, in order to make the power transmission of the motor 21 more stable, a rotating shaft 27 is installed at the output end of the motor 21 . The rotating shaft 27 and the screw 22 are coaxially arranged, and the rotating shaft 27 and the screw 22 are connected via a coupling 28 .

[0035] An upper limit switch 30 and a lower limit switch 31 are provided in the box body 10, and the limit plate 23 is located between the upper limit switch 30 and the lower limit switch 31. The upper and lower limit switches are electrically connected to the motor 21. When the upper and lower limit switches are touched, the motor 21 stops working. The setting of the upper and lower limit switches keeps the moving distance of the limit plate 23 within a certain range, so that the cabinet door 12 can just allow the first card block 15 and the second card block to overlap and stagger.

[0036] like Figure 3 and Figure 4As shown in the figure, a connecting plate 13 is installed on the cabinet door 12. The side of the connecting plate 13 is fixedly connected to the cabinet door 12. The end of the connecting plate 13 is sleeved on the lifting shaft 20. A hinge 25 is arranged between the connecting plate 13 and the lifting shaft 20 to ensure that the connecting plate 13 rotates stably on the lifting shaft 20. A shoulder 24 is arranged at the position of the lifting shaft 20 corresponding to the sleeved connecting plate 13. The shoulder 24 is used to support the connecting plate 13 to ensure that the lifting shaft 20 can push the connecting plate 13 upward during the upward movement. When the lifting shaft 20 moves downward, it will move downward synchronously under the action of the gravity of the cabinet door 12 and the hinge. A rolling bearing 26 is arranged between the shoulder 24 and the connecting plate 13 to reduce the friction between the shoulder 24 and the connecting plate 13 and enable the connecting plate 13 to rotate smoothly.

[0037] As Figure 1 shown in the figure, protective covers are arranged at both ends of the lifting shaft 20 corresponding to the box body 10 to protect both ends of the lifting shaft 20 and make the overall device structure more reasonable.

[0038] It should be understood that the above description of the specific embodiments of the present invention is only for explaining the technical route and features of the present invention, and its purpose is to enable those skilled in the art to understand the content of the present invention and implement it accordingly. However, the present invention is not limited to the above specific embodiments. Any changes or modifications made within the scope of the claims of the present invention should be covered by the protection scope of the present invention.
