Description

Technical Field

[0001] This utility model relates to the technical field of deuterium gas treatment equipment, and in particular to an automatic door structure for a deuterium gas treatment equipment. Background Technology

[0002] Deuterium gas treatment equipment places extremely high demands on the sealing and structural strength of its doors. Therefore, typical deuterium gas treatment equipment doors are equipped with numerous door bolts, which are usually controlled by individual locks, requiring manual opening and closing of the door and locking of the bolts. This results in low automation and cumbersome operation. The applicant previously filed a patent for a door structure with automatic locking bolts; therefore, how to achieve automatic opening and closing of a door with automatic locking bolts is the problem that the inventor aims to solve. Utility Model Content

[0003] In view of the shortcomings of the existing technology, the main purpose of this utility model is to provide an automatic door structure for a deuterium gas treatment device that can automatically open and close and automatically lock.

[0004] To achieve the above objectives, this utility model provides the following technical solution: an automatic door structure for a deuterium gas treatment device, comprising a device body and a door body. The door body is equipped with a main connecting plate that can be rotated by a first cylinder. The main connecting plate is linked to upper and lower transmission rods, which are respectively linked to several rotatable sub-connecting plates. Each sub-connecting plate is linked to a receiving rod, and the receiving rod is connected to a first door pin located at the top or bottom of the device body. Each sub-connecting plate is horizontally connected to a left and right transmission rod, which are rotatably connected to... A second door pin is set at the left or right end of the main body of the equipment. The upper and lower transmission rods are symmetrically arranged with respect to the center of the main connecting piece. A cylinder fixing frame and a second cylinder are set on the top of the main body of the equipment. The piston rod of the second cylinder is rotatably connected to a rotating lever. A hinge assembly is set between the main body of the equipment and the door. The door is hinged to the main body of the equipment through the hinge assembly. A rotating shaft is set on the hinge assembly. The rotating shaft is fixedly connected to the rotating lever. The second cylinder drives the rotating shaft and the door to open and close through the rotating lever.

[0005] Preferably, the hinge assembly includes a bushing fixedly mounted on the main body of the device, the rotating shaft being inserted into the bushing, and the hinge assembly further includes a movable hinge fixedly connected to the rotating shaft and fixedly connected to the door body.

[0006] Preferably, a planar bearing is fitted on the rotating shaft between the bushing and the movable hinge.

[0007] This invention has the following advantages over existing technologies: it enables automatic locking and opening / closing of the door. The automatic locking mechanism works by actuating a first cylinder, which rotates the main connecting plate 90 degrees. Simultaneously, the main connecting plate drives the upper and lower transmission rods, causing the sub-connecting plates to rotate via these rods. The rotating sub-connecting plates then drive the left and right transmission rods, thus causing the first door pin to move up and down via a receiving rod, and the second door pin to move left and right via the left and right transmission rods. This allows multiple door pins to extend or retract simultaneously.

[0008] The automatic opening and closing principle is that the second cylinder drives the rotating arm to rise or fall through the piston rod, thereby driving the rotating shaft to rotate. The rotating shaft drives the door to rotate relative to the main body of the equipment through the hinge assembly, thereby realizing the opening and closing of the door. Attached Figure Description

[0013] The present invention will be further described below with reference to the accompanying drawings.

[0014] like Figure 1As shown, an automatic door structure for a deuterium gas treatment device includes a main body 1 and a door 2. The door 2 is equipped with a rotatable main connecting piece 4 driven by a first cylinder 3. The main connecting piece 4 is linked to upper and lower transmission rods 5. Each of the upper and lower transmission rods 5 is linked to several rotatable sub-connecting pieces 6. Each sub-connecting piece 6 is linked to a receiving rod 7. The receiving rod 7 is connected to a first door pin 8 located at the top or bottom of the main body 1. Each sub-connecting piece 6 is horizontally connected to a left and right transmission rod 9. The left and right transmission rods 9 are rotatably connected to a second door pin located at the left or right end of the main body 1. Door pin 10, the upper and lower transmission rods 5 are symmetrically arranged with respect to the center of the main connecting piece 4, the top of the equipment body 1 is provided with a cylinder fixing frame 11 and a second cylinder 12 is provided on the cylinder fixing frame 11, the piston rod of the second cylinder 12 is rotatably connected to a rotating lever 13, a hinge assembly is provided between the equipment body 1 and the door 2, the door 2 is hinged to the equipment body 1 through the hinge assembly, a rotating shaft 14 is provided on the hinge assembly, the rotating shaft 14 is fixedly connected to the rotating lever 13, and the second cylinder 12 drives the rotating shaft 14 and the door 2 to open and close through the rotating lever 13.

[0015] This solution provides an automatic door structure for a deuterium gas treatment device, which enables automatic locking and opening / closing of the door body 2. The automatic locking mechanism works by actuating the first cylinder 3, which rotates the main connecting plate 4 by 90 degrees. Simultaneously, the main connecting plate 4 drives the upper and lower transmission rods 5, causing the sub-connecting plate 6 to rotate via the upper and lower transmission rods 5. The rotating sub-connecting plate 6 then drives the left and right transmission rods 9, thus causing the first door pin 8 to move up and down via the receiving rod 7, and the second door pin 10 to move left and right via the left and right transmission rods 9. This allows multiple door pins to extend or retract simultaneously.

[0016] The principle of its automatic opening and closing is that the second cylinder 12 drives the rotating lever 13 to rise or fall through the piston rod, thereby driving the rotating shaft 14 to rotate. The rotating shaft 14 drives the door body 2 to rotate relative to the main body 1 through the hinge assembly, thereby realizing the opening and closing of the door body 2.

[0017] Preferably, the hinge assembly includes a bushing 15 fixedly mounted on the device body 1, the rotating shaft 14 is inserted into the bushing 15, and the hinge assembly also includes a movable hinge 16 fixedly connected to the rotating shaft 14 and fixedly connected to the door body 2.

[0018] The advantage of this setup is that the rotating shaft 14 is installed through the bushing 15, the rotating shaft 14 rotates relative to the bushing 15, and the rotating shaft 14 is fixedly connected to the movable hinge 16. The rotation of the rotating shaft 14 drives the movable hinge 16 and the door body 2 to rotate.

[0019] Preferably, a planar bearing 17 is fitted on the rotating shaft 14 between the bushing 15 and the movable hinge 16.

[0020] The installation of a plane bearing 17 can support the rotation of the rotating shaft 14, reduce friction, bear load, and reduce operating noise.
