Description

Technical Field

[0001] The utility model relates to the technical field of sealed doors, and more specifically to a sealed door. Background Art

[0002] Traditional sealing door technology typically relies on the coordinated operation of two sets of drive cylinders: one set drives the sealing door horizontally, accurately moving it to the doorframe's opening; the other set presses the door against the doorframe once it reaches the designated position to ensure a tight seal. While this dual-drive cylinder system can meet sealing requirements to a certain extent, its relatively complex structure not only makes the sealing door system bulkier, limiting its application in space-constrained environments, but also increases manufacturing costs, makes installation more difficult, and hinders maintenance and repair.

[0010] In one embodiment, when the driving mechanism drives the movable plate to move horizontally toward the limiting column to the third position, it simultaneously drives the connecting rod to rotate until the connecting rod and the limiting column are parallel, and the connecting rod drives the sealing plate to move along the limiting column guide to the sealing position through the roller.

[0027] In order to make the purpose, technical solutions and advantages of the present invention more clear, the present invention will be further described in detail below with reference to the accompanying drawings and specific implementation methods.

[0028] The following will be combined with the drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the embodiments described are part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without making creative efforts are within the scope of protection of the present invention.

[0030] It should also be understood that the terms used in this utility model specification are only for the purpose of describing specific embodiments and are not intended to limit the utility model. As used in this utility model specification and the appended claims, the singular forms "a", "an" and "the" are intended to include plural forms unless the context clearly indicates otherwise.

[0031] It should be further understood that the term “and / or” used in the present specification and the appended claims refers to any and all possible combinations of one or more of the associated listed items, and includes these combinations.

[0032] See also Figures 1 to 8 As shown, the utility model discloses a sealed door, comprising: a door frame 1, a mounting bracket 2, a sealing plate 3, a movable plate 4, a driving mechanism 5 and a telescopic mechanism 6; the mounting bracket 2 is fixedly connected to the side of the door frame 1, the movable plate 4 is connected to the sealing plate 3 through the telescopic mechanism 6, and the driving mechanism 5 is arranged on the mounting bracket 2. The driving mechanism 5 is used to drive the movable plate 4 to move horizontally, so as to drive the sealing plate 3 to resist or move away from the door frame 1 through the telescopic mechanism 6.

[0033] Specifically, in this embodiment, the sealing plate 3 is connected to the movable plate 4 via a telescopic mechanism 6, and the driving mechanism 5 is used to drive the movable plate 4 to move horizontally. Under the linkage action of the telescopic mechanism 6, the movable plate 4 drives the sealing plate 3 to move horizontally to the opening of the door frame 1, and further drives the sealing plate 3 close to the opening of the door frame 1 until it is sealed. When resetting is required, the driving mechanism 5 drives the movable plate 4 to move horizontally in the opposite direction. Under the linkage action of the telescopic mechanism 6, the movable plate 4 drives the sealing plate 3 out of the sealing position and further drives the sealing plate 3 away from the opening of the door frame 1. It can be understood that in this embodiment, there is no need to use two sets of driving mechanisms 5 to respectively achieve the horizontal displacement and clamping functions of the sealing plate 3. Only one set of driving mechanisms 5 is required to drive the movable plate 4 to move horizontally. The horizontal displacement, clamping, and resetting functions of the sealing plate 3 are achieved through the linkage action of the telescopic mechanism 6. This greatly simplifies the system structure, reduces manufacturing costs and installation complexity, and improves space utilization.

[0034] Furthermore, this embodiment includes four telescopic mechanisms 6, which are arranged in an array on the movable plate 4 to ensure that the force exerted by the telescopic mechanisms 6 on the sealing plate 3 meets the sealing requirements. In actual production, the number of telescopic mechanisms 6 can be increased or decreased as needed to meet the requirements of different sealing devices.

[0035] In one embodiment, the telescopic mechanism 6 includes a base 61 and a connecting rod 62. The base 61 is fixedly connected to the movable plate 4. The movable plate 4 is provided with an air avoidance groove 41. The base 61 is provided with a first connecting shaft 611. A second connecting shaft 32 is provided in the sealing plate 3. One end of the connecting rod 62 is rotatably connected to the first connecting shaft 611, and the other end passes through the air avoidance groove 41 and is rotatably connected to the second connecting shaft 32.

[0036] Specifically, the fixed plate is fixedly connected to the movable plate 4 so that the telescopic mechanism 6 can move horizontally in sync with the horizontal movement of the movable plate 4. A connecting rod 62 has one end rotatably connected to the first connecting shaft 611 of the base 61, and the other end rotatably connected to the second connecting shaft 32 of the sealing plate 3. This allows the connecting rod 62 to smoothly rotate synchronously within the base 61 and the sealing plate 3 when the telescopic mechanism 6 moves horizontally, thereby driving the sealing plate 3 to complete horizontal movement or compression and disengagement.

[0037] In one embodiment, a retaining post 7 is provided on the side of the mounting bracket 2 proximate to the sealing plate 3. A roller 31 is provided on the side of the sealing plate 3 proximate to the retaining post 7. The roller 31 is positioned flush with the retaining post 7. Specifically, the drive mechanism 5 drives the movable plate 4 to move horizontally. The movable plate 4, in conjunction with the telescopic mechanism 6, drives the sealing plate 3 horizontally until the roller 31 abuts the retaining post 7. At this point, the sealing plate 3 is positioned directly above the opening of the door frame 1.

[0038] In one embodiment, when the movable panel 4 is in the first position, the connecting rod 62 is tilted, and the sealing plate 3 is away from the opening of the door frame 1. Specifically, when the sealed door is in the open state, the movable panel 4 is in the first position, and the sealing plate 3 is in the initial state. At this time, the connecting rod 62 is tilted, and there is a gap between the sealing plate 3 and the door frame 1 in both the vertical and horizontal directions.

[0039] In one embodiment, when the driving mechanism 5 drives the movable plate 4 to move horizontally toward the limiting column 7 to the second position, the movable plate 4 drives the sealing plate 3 to move horizontally through the connecting rod 62 until the roller 31 abuts against the limiting column 7, and the edge of the sealing plate 3 coincides with the edge of the opening of the door frame 1.

[0040] Specifically, the driving plate drives the movable plate 4 to move horizontally toward the limit column 7, the movable plate 4 drives the telescopic mechanism 6 to move horizontally synchronously, and the connecting rod 62 pushes the sealing plate 3 to move horizontally until the roller 31 abuts against the limit column 7. At this time, the sealing plate 3 is located directly above the opening of the door frame 1, and the connecting rod 62 is in an inclined state.

[0041] In one embodiment, when the driving mechanism 5 drives the movable plate 4 to move horizontally toward the limiting column 7 to the third position, it simultaneously drives the connecting rod 62 to rotate until the connecting rod 62 and the limiting column 7 are parallel. The connecting rod 62 drives the sealing plate 3 to move along the limiting column 7 to the sealing position through the roller 31.

[0042] Specifically, the driving mechanism 5 continues to drive the movable plate 4 to move horizontally toward the limiting column 7. At this time, the roller 31 on the sealing plate 3 has been abutted against the limiting column 7 and cannot complete the horizontal movement synchronously. The movable plate 4 drives the base 61 to move horizontally, and one end of the connecting rod 62 on the base 61 moves horizontally synchronously. The other end of the connecting rod 62 hinged on the sealing plate 3 is vertically displaced toward the opening of the door frame 1. The connecting rod 62 pushes the sealing plate 3 to move vertically toward the opening of the door frame 1 along the guiding action of the limiting column 7 under the action of the roller 31 until it reaches the sealing position. At this time, the connecting rod 62 is parallel to the limiting column 7. The connecting rod 62 pushes the sealing plate 3 to be tightly connected with the opening of the door frame 1, and the sealed door is in a sealed state. It can be understood that the rolling of the roller 31 reduces the force required to squeeze the sealing plate 3 toward the opening of the door frame 1, which helps the sealing plate 3 slide quickly.

[0043] Furthermore, when the sealed door needs to be reset, the drive mechanism 5 drives the movable plate 4 horizontally from the third position to the second position. The connecting rod 62 transitions from a vertical position to an inclined position, guiding the sealing plate 3 along the stopper 7 away from the opening of the door frame 1 and out of the sealed position. The drive mechanism 5 continues to drive the movable plate 4 horizontally from the second position to the first position. The inclined connecting rod 62 simultaneously pulls the sealing plate 3 horizontally, moving it horizontally away from the opening of the door frame 1. At this point, the sealed door completes its reset.

[0044] In one embodiment, the telescopic mechanism 6 includes an elastic component, which includes a fixing frame 63 and an elastic member 64. The ends of the elastic member 64 are respectively connected to the sealing plate 3 and the fixing frame 63. Specifically, a connecting rod 33 for hanging the elastic member 64 is provided in the sealing plate 3. During actual use, because the driving mechanism 5 drives the movable plate 4 to move horizontally at a high speed, the telescopic mechanism 6 also moves horizontally at a high speed. The elastic member 64 is used to apply a force in the opposite direction between the telescopic mechanism 6 and the sealing plate 3, thereby buffering the movement of the sealing plate 3, preventing the sealing plate 3 from moving too quickly and being damaged, and improving the service life of the sealed door. It will be understood that in this embodiment, the elastic member 64 is preferably a spring, and the spring stiffness is selected according to actual usage.

[0045] In one embodiment, the drive mechanism 5 includes a drive cylinder 51 and a guide mechanism 52. The drive cylinder 51 is connected to the mounting bracket 2 and is in transmission connection with the guide mechanism 52. Specifically, in this embodiment, the drive mechanism 5 only requires a single drive cylinder 51, which is used to drive the movable plate 4 to slide along the guide mechanism 52, thereby enabling the movable plate 4 to smoothly move horizontally. This, through the coordinated action of the telescopic mechanism 6, sequentially completes the horizontal movement and compression and disengagement of the sealing plate 3. Furthermore, in other embodiments, the drive cylinder 51 and a screw rod or other drive mechanism 5 may be used in place of the drive cylinder 51, depending on actual production conditions.

[0046] In one embodiment, a door panel 8 is further included, disposed on the side of the movable panel 4 away from the door frame 1. A connecting post 42 is provided on the movable panel 4, connected to the side of the door panel 8 that is closer to the door frame 1. Specifically, one end of the connecting post 42 is fixedly connected to the movable panel 4, and the other end is fixedly connected to the door panel 8. The door panel 8 is a box-shaped member, with a receiving cavity provided on the side closer to the door frame 1 to protect the telescopic mechanism 6 on the movable panel 4 and prevent damage or malfunction caused by external forces during operation.

[0047] In one embodiment, an annular sealing ring (not shown) is provided on one side of the sealing plate 3 facing the opening of the door frame 1. Specifically, the sealing ring is provided to further ensure the sealing effect.

[0048] In summary, the sealed door of this embodiment utilizes a drive mechanism to horizontally displace the movable plate, which, through the interlocking action of the telescopic mechanism, drives the sealing plate to horizontally displace and compress and release, thereby achieving controlled opening and closing of the sealed door. This not only simplifies the mechanical structure of the sealed door, reducing manufacturing costs and maintenance, but also improves the overall efficiency and operational stability of the system.
