Description

Technical Field

[0001] This application relates to the technical field of isolators, and particularly to a damping door for an isolator. Background Art

[0002] In the prior art, the transfer cabin door of an isolator usually adopts tempered glass material and is installed on the transfer cabin through hinges, and can be opened in a fan shape in the horizontal direction. The seal between the cabin door and the transfer cabin is achieved by means of an inflatable sealing strip.

[0003] However, in actual use, there are many problems. On the one hand, due to the uneven ground where the isolator is placed or the accidental touch when the experimental operator walks, the opened transfer cabin door often closes by itself. During the closing process, the cabin door will collide hard with the wall surface of the transfer cabin. Over time, it is very easy to cause the tempered glass of the transfer cabin door to break.

[0004] On the other hand, when it is detected that the transfer cabin door is closed, the inflatable sealing strip will be inflated to achieve the sealing effect. But if the transfer cabin door rebounds after the collision and fails to close completely in place, the inflation of the inflatable sealing strip at this time will not be able to achieve effective sealing, thus seriously affecting the normal use. Utility Model Content

[0005] The purpose of this application is to provide a damping door for an isolator in view of the above problems existing in the prior art.

[0006] In order to achieve the above application purpose, this application adopts the following technical solutions: A damping door for an isolator includes:

[0007] A transfer cabin door;

[0008] A cabin door hinge seat, installed on the wall surface of the transfer cabin of the isolator;

[0009] A cabin door hinge, connecting the cabin door hinge seat and the transfer cabin door to realize the rotational connection between the transfer cabin door and the wall surface of the transfer cabin;

[0010] Damping rotating shafts, arranged at both ends in the length direction of the cabin door hinge seat, one end of each damping rotating shaft is connected to the cabin door hinge seat, and the other end is connected to the cabin door hinge;

[0011] Washers, installed on the outer ring of the damping rotating shafts and located between the cabin door hinge seat and the cabin door hinge, providing resistance through the damping rotating shafts.

[0012] Further, connection holes for fixing the damping rotating shafts are provided on both the cabin door hinge seat and the cabin door hinge, and mounting holes corresponding to the connection holes are provided at both ends in the length direction of the damping rotating shafts.

[0013] Further, the washer is a copper washer.

[0014] Furthermore, mounting through holes for mounting the damping shaft are provided at both ends of the door hinge in the length direction.

[0015] Furthermore, each damping shaft includes a cylindrical middle section and connecting sections located at both ends of the middle section in the length direction, and each connecting section is provided with a mounting hole.

[0016] Furthermore, each mounting through hole is closed by a plug.

[0017] Furthermore, the damping shaft is connected and fixed to the door hinge seat and the door hinge via a hexagonal cone-end set screw.

[0018] Furthermore, the door hinge is provided with a notch which cooperates with the door hinge seat.

[0023] 2. Improve the stability of the sealing effect: It can ensure that the door of the transfer compartment is accurately in place when closing, avoiding the impact of the sealing effect of the inflatable sealing strip due to the collision rebound, thereby ensuring the sealing and use effect of the transfer compartment.

[0024] 3. Enhanced ease of use: The hatch can stay stably at the required opening and closing angle, which is convenient for experimental operators to operate and improves work efficiency.

[0025] 4. Adaptable to different environments and requirements: The damping shaft can select different torques according to the size of the transfer compartment door and the length of the lever arm to meet different usage environments and requirements.

[0026] 5. Reasonable structural design: The components are tightly connected and work well together. Installation and maintenance are relatively simple, which improves the overall reliability and durability. BRIEF DESCRIPTION OF THE DRAWINGS

These are only for the convenience of describing the present application and simplifying the description, rather than indicating or implying that the device or element referred to must have a specific orientation, be constructed and operated in a specific orientation. Therefore, the above terms should not be construed as limitations to the present application.

[0034] Embodiment 1

[0035] As Figures 1-3 shown, a damping door for an isolator includes a transfer cabin hatch 3, a hatch hinge seat 1, a hatch hinge 2, a damping rotating shaft 8, and a copper washer 7. The hatch hinge seat 1 is fixedly installed on the wall surface of the transfer cabin of the isolator. The hatch hinge 2 connects the hatch hinge seat 1 and the transfer cabin hatch 3 to achieve the rotational connection between the transfer cabin hatch 3 and the wall surface of the transfer cabin. Damping rotating shafts 8 are arranged at both ends in the length direction of the hatch hinge seat 1. One end of each damping rotating shaft 8 is connected to the hatch hinge seat 1, and the other end is connected to the hatch hinge 2. The copper washer 7 is installed on the outer ring of the damping rotating shaft 8 and is located between the hatch hinge seat 1 and the hatch hinge 2.

[0036] In actual use, when the transfer cabin hatch 3 is opened, the resistance generated by the damping rotating shaft 8 and the copper washer 7 enables the hatch to stop at any angle (the damping rotating shaft 8 provides the main resistance) and will not freely close due to accidental touch. The operator can easily keep the hatch at the required opening and closing angle, facilitating the operation of item transfer.

[0037] Among them, the damping rotating shaft 8 is a commercially available product. The preferred model is DT10XT 10X57mm, also known as the one-word rotating shaft, which is applicable to the damping hinges of products such as notebooks and monitors. It can achieve stopping at any angle and can also customize the torque size from the manufacturer. The specific physical diagram is as Figure 4 shown. Since it is prior art, the specific principle and structure will not be elaborated.

[0038] Embodiment 2

[0039] For the damping door of the isolator in this embodiment, in addition to the above basic structure, connection holes for fixing the damping rotating shaft 8 are provided on both the hatch hinge seat 1 and the hatch hinge 2, and mounting holes corresponding to the connection holes are provided at both ends of the damping rotating shaft 8 in the length direction. The damping rotating shaft 8 is connected and fixed to the hatch hinge seat 1 and the hatch hinge 2 through the hexagon socket set screws 6.

[0040] During the operation, this firm connection method ensures the stability of the damping rotating shaft 8, enabling it to continuously and effectively exert the damping effect. Regardless of the frequency and amplitude of the hatch opening and closing, the stable stop of the hatch can be guaranteed.

[0041] Embodiment 3

[0042] In this embodiment, mounting through holes for installing the damping rotating shaft 8 are provided at both ends of the hatch hinge 2 of the damping door of the isolator in the length direction, and each mounting through hole is closed by a plug 5. A step for installing the copper washer 7 is provided on the hatch hinge seat 1. The copper washer 7 is installed in the step and at least partially protrudes from the step to abut against the hatch hinge 2.

[0043] Such a structural design further optimizes the damping effect. The setting of the plug 5 prevents impurities such as dust from entering the mounting through holes, ensuring the normal operation of the damping rotating shaft 8. The installation position of the copper washer 7 in the step makes the friction with the hatch hinge 2 more uniform, improving the stability of the damping.

[0044] A door handle 4 is also provided on the transfer cabin hatch 3, which facilitates the operator to open and close the hatch. In practical applications, for example, in a biological laboratory, this design can provide a convenient, stable and safe operation experience for the experimenters, ensuring the smooth progress of the experiment.

[0045] The parts not detailed in this application are prior art, so they are not elaborated in this application.

[0046] It can be understood that the term "one" should be understood as "at least one" or "one or more". That is, in one embodiment, the number of an element can be one, while in other embodiments, the number of this element can be multiple. The term "one" cannot be understood as a limitation on the number.

[0047] Although terms such as hatch hinge seat 1, hatch hinge 2, transfer cabin hatch 3, door handle 4, plug 5, socket head cap screw 6, copper washer 7, damping rotating shaft 8, etc. are used more frequently in this text, the possibility of using other terms is not excluded. The use of these terms is only for the convenience of describing and explaining the essence of this application; interpreting them as any additional restrictions is contrary to the spirit of this application.

[0048] This application is not limited to the above-mentioned best implementation mode. Anyone can obtain other various forms of products under the inspiration of this application. However, no matter what changes are made in its shape or structure, as long as it has the same or similar technical solutions as this application, it falls within the protection scope of this application.
