However, during the assembly process, the isolator needs to be welded and assembled first, and then the pneumatic door is assembled. During the welding process, the cavity side wall of the isolator will be deformed due to heat. After deformation, the entire cavity side of the isolator will be uneven, which will cause the position of the fixed block to change. For example, one fixed block protrudes from the plane of the cavity side, while the other fixed block has a certain depression compared to the plane of the cavity side. As a result, the upper and lower positions of the sliding rail of the air cylinder are not in the same plane, which causes the air cylinder to run smoothly during sliding, and even gets stuck, so that the pneumatic door runs smoothly, which affects the sealing effect of the transmission channel between the cavities of the isolator.

Detailed Implementation

[0027] Clearly, the described embodiments are merely a part of the embodiments of the present application, rather than all the embodiments. Based on the embodiments of the present application, all other embodiments obtained by those skilled in the art without creative labor fall within the scope of the present application.

[0028] In the present embodiment, the isolator automatic lifting door device 1 can be applied to an isolator in the pharmaceutical industry, for example. As shown in the drawings, Figures 1-3 The isolator automatic lifting door device 1 comprises, for example, a door frame member 20, a driving assembly 30, and a door plate member 60.

[0029] Specifically, the door frame member 20 is arranged on the cavity wall 10 of the isolator and surrounds the side wall of the door hole 101 of the isolator. The cavity wall 10 can be located on the inner side wall of the isolator, as shown in the drawings, Figure 1 The door hole 101 can be a mouse hole in the isolator, for example, which can be used to connect the inside of the isolator and a transfer device, allowing the transfer of materials without destroying the sterile environment inside the isolator. The mouse hole can be a passage arranged at the joint of the front cavity and the rear cavity of the isolator, for example. The door frame member 20 can be a door frame, which can be a ring-shaped door frame arranged around the periphery of the mouse hole, for example. The door frame can be a machined part, as shown in the drawings, Figure 8 The thickness d1 of the door frame member is 20 mm, and the surface flatness is very high (usually ≤0.1 mm) because it is machined.

[0030] The driving assembly 30 is arranged on the side of the door frame member 20 away from the door hole 101 and is connected with the door frame member 20. The door plate member 60 is arranged on the side of the driving assembly 30 away from the cavity wall 10, and the door plate member 60 is slidably connected with the door frame member 20 through the driving assembly 30. The door plate member 60 can be a door plate, and the driving assembly 30 can be a cylinder driving assembly, which can comprise a cylinder and a fixed plate connected with the cylinder, for example. The fixed plate can be fixed on the side of the door frame, so that the cylinder can fix the side of the door frame. When it is necessary to seal the cavity in the isolator, the cylinder is controlled to move downward, thereby driving the door plate to move downward, and the door plate can be moved downward to isolate the cavity. When it is not necessary to seal, the cylinder is controlled to move upward, thereby driving the door plate to move upward and away from the cavity, so that the front cavity and the rear cavity of the isolator are connected and communicated.

[0031] As the prior art installs the fixed block of the air cylinder on the cavity side wall of the isolator, when welding assembly, it is easy to cause the cavity side wall of the isolator to be deformed, so that the sliding track of the air cylinder is not in the same plane, so that the sliding operation of the air cylinder is not smooth, which affects the sealing between the door plate and the cavity of the isolator. In the embodiment, the driving assembly 30 is connected with the door frame piece 20, and the door frame piece 20 is connected with the cavity wall 10, which can avoid the direct connection of the driving assembly 30 on the cavity wall 10, so as to prevent the cavity wall 10 from being deformed during welding assembly, thereby affecting the smooth operation of the driving assembly 30, improving the sealing of the isolator automatic lifting door device 1, and reducing the influence of the cavity wall 10 on the operation of the air cylinder in the driving assembly 30, avoiding repair, saving labor, and reducing operation cost.

[0032] Further, as shown in Figure 4 , Figure 6 and Figure 7 , the door frame piece 20 is provided with a through hole 201 and a first connecting part 21, the through hole 201 is communicated with the door hole 101, and the first connecting part 21 is arranged on the side of the door frame piece 20 away from the through hole 201, and the driving assembly 30 is fixedly connected with the door frame piece 20 through the first connecting part 21. The through hole 201 may, for example, be a through hole formed at the middle position of the door frame piece 20, and the door frame piece 20 may, for example, be a ring-shaped hollow structure door frame, and the hollow part forms the through hole. The through hole 201 can be used to communicate with the door hole 101, so that the door frame piece 20 can be arranged around the side wall of the door hole 101. The first connecting part 21 may, for example, be a structure of connecting hole and screw, the connecting hole is arranged on the side of the outer surface of the door frame piece, and the driving assembly 30 can be provided with a mounting hole corresponding to the connecting hole, and then the driving assembly 30 is fixedly installed on the side of the door frame piece 20 by screwing the screw through the mounting hole and the connecting hole respectively. Thus, the driving assembly 30 can be fixed on the door frame piece 20, further reducing the influence of the deformation of the cavity wall 10 on the driving assembly 30, and reducing the difficulty of disassembly.

[0033] Further, as shown in Figure 6As shown, the door frame member 20 is further provided with a second connecting portion 22, which is arranged on the side of the door frame member 20 away from the cavity wall 10 and adjacent to the first connecting portion 21, and the driving assembly 30 is fixedly connected with the door frame member 20 through the first connecting portion 21 and the second connecting portion 22. The second connecting portion 22 can be, for example, a combined structure of a connecting screw hole and a screw, and the screw can pass through a through hole corresponding to the connecting screw hole on the driving assembly 30 to realize the fixation of the screw in the connecting screw hole, so that the driving assembly 30 can be further fastened on the side edge of the door frame member 20. The lateral arrangement of the driving assembly 30 makes full use of the limited space inside the isolator and reduces the distance from the door plate member 60 to the cavity wall 10. As shown in Figure 6 As shown, the end face of the end of the door frame member 20 away from the door plate member 60 can be formed with a side edge similar to a stepped structure, so that the first connecting portion 21 and the second connecting portion 22 can be conveniently fixed on the side edge of the door frame member 20 in cooperation with the driving assembly 30.

[0034] Further, as shown in Figure 7 As shown, the door frame member 20 is further provided with a protruding portion 23, which is arranged around the side wall of the through hole 201; the protruding portion 23 extends away from the door frame member 20 towards the cavity wall 10 and penetrates into the door hole 101. The protruding portion 23 can be, for example, a raised edge portion on the door frame member 20, which extends outwardly away from the door frame member 20 towards the cavity wall 10. The arrangement of the protruding portion 23 can make the door frame member 20 welded on the door hole 101 through the raised edge, that is, the protruding portion 23 can be regarded as a welding position of the door frame member 20, which is welded on the door hole 101 through the protruding portion 23, so as to reduce the deformation of the door frame member 20 and the influence on the driving operation of the driving assembly 30.

[0035] Further, as shown in Figures 1-4As shown, the driving assembly 30 may, for example, include a driving member 40 and a mounting member 50. The driving member 40 is fixedly connected with the mounting member 50, the mounting member 50 is fixedly connected with the door frame member 20 through the first connecting portion 21, and the door plate member 60 is slidingly connected with the door frame member 20 through the driving member 40. The driving member 40 may, for example, be a structure composed of a sliding block, a fixed block and a sliding rail, which may, for example, be a cylinder assembly, and the mounting member 50 may, for example, be a fixed plate, which may, for example, be a cylinder fixed plate. The fixed block may, for example, be two, which are respectively arranged on the two ends of the fixed plate, the two ends of the sliding rail are respectively connected with the two fixed blocks, the sliding block slides on the sliding rail, and the fixed plate is fixedly connected with the door frame member 20. Through the cooperation of the driving member 40 and the mounting member 50, the driving member 40 can be fixed on the side edge of the door frame member 20, so that the influence of the deformation of the cavity wall on the driving member 40 can be further reduced. In the embodiment, the number of the driving member 40 and the mounting member 50 is two, and the two mounting members 50 and the two driving members 40 are respectively arranged on the left and right sides of the door frame member 20.

The guide rod 41 may, for example, be a combined structure of a sliding rail and two fixed blocks, the sliding rail is fixed on the mounting member 50 through the two fixed blocks, and then the sliding block 42 is arranged on the sliding rail, so that the sliding block can slide on the guide rod 41, thereby driving the door plate member 60 to move up and down.

[0037] Further, as shown in Figure 5 The mounting member 50 may, for example, include a mounting member main body portion 51 and a third connecting portion 52, the mounting member main body portion 51 is arranged on the side edge of the door frame member 20 away from the through hole 201 and is fixedly connected with the first connecting portion 21, and the third connecting portion 52 is arranged on the end portion of the mounting member main body portion 51 and extends towards the direction away from the through hole 201 of the door frame member 20, and the end portion of the guide rod 41 is fixedly connected with the third connecting portion 52. The mounting member main body portion 51 may, for example, be a mounting fixed plate, and the third connecting portion 52 may, for example, be a connecting plate arranged at the two ends of the mounting fixed plate, which can extend outward, and the two ends of the guide rod 41 are respectively arranged on the connecting plates.

[0038] Further, the mounting body part 51 comprises a first body part 511 and a second body part 512, the second body part 512 is fixedly connected with the first connecting part 21, the first body part 511 is connected with the second body part 512, and the first body part 511 extends from the side of the second body part 512 away from the door frame part 20 to the direction close to the door hole 101. The first body part 511 and the second body part 512 may, for example, be two fixed plates on a mounting fixed plate, and the two fixed plates may be connected vertically. In this embodiment, the first body part 511 and the second body part 512 may be obtained by mechanical integral machining, so that the cross section between the first body part 511 and the second body part 512 may be L-shaped, thereby improving the rigidity of the mounting 50, so that the mounting 50 is not easy to deform. The mounting 50 and the door frame part 20 form a stable frame structure in the direction parallel and perpendicular to the cavity wall 10, thereby improving the stability of supporting the door plate part 60. In addition, since the mounting body part 51 comprises the first body part 511 and the second body part 512, a step part may be provided on the side of the door frame part, so that the first body part 511 and the second body part 512 can correspond to the first connecting part 21 and the second connecting part 22 respectively, the first body part 511 is fixedly connected with the first connecting part 21, and the second body part 512 is fixedly connected with the second connecting part 22, thereby further reducing the deformation of the mounting 50.

For example, the surface of the first body part 511 is provided with three adjusting screws for adjusting the flatness of the installation, when there is a slight deformation in the upper end of the first body part 511, or because the cavity wall near the installation part 50 is deformed greatly, the adjusting screws can be adjusted within a certain range to adjust the stress position of the mounting 50, thereby improving the flatness of the mounting 50 and avoiding affecting the smooth sliding of the sliding block 42 on the guide rod 41.

[0040] Further, as Figure 1 and Figure 6As shown, the door frame member 20 is provided with a sealing part 24, which is located between the door frame member 20 and the door hole 101 and sealingly connects the door frame member 20 and the door hole 101. The sealing part 24 may, for example, be an inflatable sealing part, which can be inflated when sealing is required, i.e. the sealing part 24 is inflated to fill between the door frame member 20 and the door hole 101, thereby increasing the sealing between the automatic lifting door device 1 and the isolator cavity. Since the door frame member 20 has sufficient thickness, it is suitable for various types of sealing parts, in particular inflatable sealing parts, to sufficiently seal between the door plate member 60 and the cavity wall 10. At the same time, it can also ensure that the inflatable sealing part is completely accommodated in the door frame member 20 during opening and closing of the door plate member 60, thereby effectively reducing the probability of damage to the sealing part caused by scratching of the door plate member 60.
