Description

Technical Field

[0001] The utility model relates to the technical field of protective plates, in particular to a protective plate for the inner wall of a vacuum chamber. Background Art

[0002] A vacuum chamber is a container that maintains a vacuum state inside. The production of a vacuum chamber must take into account the volume, material, and shape. Stainless steel is the main structural material of the current ultra-high vacuum system, and the inner wall of the vacuum wall is usually protected by a protective plate. Some previous vacuum chamber containers are usually equipped with an inner barrel for evacuating the vacuum chamber, but the shell of such a vacuum chamber container and its own inner barrel are usually welded and supported by a simple frame. When the vacuum container faces internal or external pressure, the external pressure can easily deform the shell of the vacuum container and compress the inner barrel inside it, and the inner barrel is also prone to being stretched and deformed due to the lack of effective protection when it is subjected to outward expansion pressure.

[0003] A Chinese utility model patent with publication number CN218987253U discloses a vacuum chamber inner wall protection plate, comprising a vacuum chamber container and an inner barrel, and also comprising an inner protection structure, wherein the inner protection structure comprises a rhombus frame, a lining angle, an outer convex strip, an embedded tube, a thickening plate and a fixed groove, wherein the inner wall of the vacuum chamber container is welded with a thickening plate at four points, the outer wall of the inner barrel is sleeve-welded with a rhombus frame, and lining angles for enhancing welding are welded between the inner four corner walls of the rhombus frame and the inner barrel, and an inner protection structure for inner wall protection is arranged between the vacuum chamber container and its inner barrel, and after the inner protection structure on the inner wall of the vacuum chamber container is assembled between the inner barrel and the vacuum chamber container, when the vacuum chamber container is subjected to external force, the inner protection structure plays an inner support to protect the inner wall of the vacuum chamber container from being deformed by force, and at the same time, when the inner protection structure is provided between the vacuum chamber container and the inner barrel as a support, the outer wall of the inner barrel is also strengthened and not easily deformed by air pressure.

[0004] With respect to the above-mentioned related technologies, the inventor believes that there are the following defects: the above-mentioned device limits the inner barrel by the mutual cooperation between the embedded tube, the outer convex strip and the diamond frame, thereby reducing the probability of damage to the inner barrel. When the staff installs the inner barrel, the staff needs to simultaneously connect multiple embedded tubes with the thickening plate. Since the embedded tube, the outer convex strip and the diamond frame are fixed to each other by welding, in actual operation, some embedded tubes are easily stuck on the thickening plate due to tolerance, which makes installation difficult. Utility Model Content

[0005] In order to solve the above problems, the utility model provides a vacuum chamber inner wall protection plate.

[0006] The above technical purpose of the utility model is achieved through the following technical scheme: a vacuum chamber inner wall protection plate, including a vacuum chamber container, a mounting groove is provided on the bottom surface of the vacuum chamber container, an inner barrel is arranged in the mounting groove, a mounting frame is fixed on the side wall of the inner barrel, a plurality of fixed plates distributed in a circular array are fixed on the side wall of the mounting frame, a sliding groove is provided on the side wall of the fixed plate, a slide plate is slidably arranged in the sliding groove, and a driving component for driving the slide plate is arranged on the fixed plate.

[0007] By adopting the above technical solution, when the staff needs to install the inner barrel, the staff needs to connect the installation frame and the inner barrel with each other, and connect the inner barrel with the installation groove with each other, so that the inner barrel can be initially stabilized. Then, the staff needs to start the driving assembly, so that the sliding plate can move away from the fixing plate under the action of the driving assembly, and then the sliding plate is pressed against the thickening plate, so that the inner barrel can be stabilized, thereby reducing the probability of damage to the inner barrel.

[0008] Furthermore, a rounded corner is provided at the upper end of the inner wall of the installation groove to reduce the difficulty of installing the inner barrel for the workers.

[0009] By adopting the above technical solution, the difficulty for the workers to connect the inner barrel and the installation groove is reduced, thereby reducing the installation difficulty for the workers.

[0010] Furthermore, a driving groove is provided on the inner top wall of the slide groove, and a threaded groove is provided through the inner top wall of the driving groove. The driving assembly includes a driving plate slidably arranged in the driving groove, a threaded rod rotatably arranged on the upper surface of the fixed plate, and a thickening plate embedded in the inner wall of the vacuum chamber container. The upper end of the threaded rod extends outside the driving plate and is threadedly connected to the threaded groove. An inclined surface is provided on the edge where the upper surface of the slide plate intersects with the side wall away from the thickening plate.

[0011] By adopting the above technical solution, when the staff connects the inner barrel and the mounting groove to each other, the staff only needs to rotate the threaded rod to make the driving plate move downward under the action of the threaded rod, and then make the driving plate press against the inclined surface, so that the sliding plate moves toward the direction close to the thickening plate and presses against the thickening plate under the action of the driving plate, thereby improving the stability of the inner barrel.

[0012] Furthermore, a stabilizing spring is fixed on the side wall of the slide plate, and the other end of the stabilizing spring is fixed on the inner wall of the slide groove.

[0013] By adopting the above technical solution, when the staff resets the threaded rod, the slide plate is automatically reset under the action of the stabilizing spring, and the staff does not need to manually move the slide plate, thereby reducing the operating difficulty of the staff and reducing the difficulty for subsequent staff to remove the inner barrel.

[0014] Furthermore, a plurality of placement grooves corresponding to the slide plates are formed on the side wall of the thickened plate close to the mounting frame.

[0015] By adopting the above technical solution, when the slide plate moves toward the direction close to the thickening plate under the action of the driving plate, the slide plate and the mounting groove are connected to each other, so that the mounting groove limits the slide plate, thereby reducing the probability of the inner barrel shaking when subjected to external force.

[0016] Furthermore, a rubber sheet is provided on the side wall of the slide plate away from the fixed plate.

[0017] Furthermore, the side wall of the driving plate away from the thickening plate is flush with the inner wall of the sliding groove away from the thickening plate.

[0018] By adopting the above technical solution, when the rubber sheet presses against the inner wall of the placement groove, the driving plate presses against the side wall of the slide plate away from the placement groove, so that the driving plate blocks the slide plate, thereby reducing the probability of the slide plate resetting at this time.

[0019] Furthermore, a handle is provided at the upper end of the threaded rod to reduce the difficulty for workers to rotate the threaded rod.

[0020] In summary, the utility model has the following beneficial effects:

[0021] 1. In this application, when the staff needs to install the inner barrel, the staff needs to connect the installation frame and the inner barrel, and connect the inner barrel and the installation groove to each other, so that the inner barrel can be initially stabilized. Then, the staff needs to start the driving assembly, so that the slide plate can move away from the fixed plate under the action of the driving assembly, and then the slide plate can be pressed against the thickening plate, so that the inner barrel can be stabilized, thereby reducing the probability of damage to the inner barrel;

[0022] 2. In the present application, after the staff connects the inner barrel and the mounting groove, the staff only needs to rotate the threaded rod to move the driving plate downward under the action of the threaded rod, thereby making the driving plate close to the inclined surface, so that the sliding plate moves toward the direction close to the thickening plate under the action of the driving plate and close to the thickening plate, thereby improving the stability of the inner barrel;

[0023] 3. In the present application, when the staff resets the threaded rod, the slide plate is automatically reset under the action of the stabilizing spring, and the staff does not need to manually move the slide plate, thereby reducing the difficulty of operation for the staff and reducing the difficulty for subsequent staff to remove the inner barrel.

[0031] like Figure 1-5 As shown, the embodiment of the present application discloses a vacuum chamber inner wall protection plate, including a vacuum chamber container 1, an inner barrel 2, a mounting frame 21, a fixing plate 3, a slide plate 4, a driving assembly 5, a stabilizing spring 6, a rubber sheet 71 and a handle 8. The bottom surface of the vacuum chamber container 1 is provided with a mounting groove 11, and the inner barrel 2 is arranged in the mounting groove 11. The mounting frame 21 is fixed on the side wall of the inner barrel 2, the fixing plate 3 is a rectangular plate-shaped structure, and the fixing plates 3 are provided in multiple and distributed in a circular array on multiple side walls of the mounting frame 21. The slide plate 4 is a rectangular plate-shaped structure, and the slide plate 4 is slidably arranged in the slide groove 31.

[0032] A driving groove 41 is provided on the inner top wall of the slide groove 31, and a threaded groove 42 is provided through the inner top wall of the driving groove 41. The driving assembly 5 is arranged on the fixed plate 3 for driving the slide plate 4, and the driving assembly 5 comprises a driving plate 51, a threaded rod 52 and a thickening plate 53. The driving plate 51 is a rectangular plate-like structure, and the driving plate 51 is slidably arranged in the driving groove 41. The threaded rod 52 is rotatably arranged on the upper surface of the fixed plate 3, and the upper end of the threaded rod 52 extends to the outside of the driving plate 51 and is threadedly connected with the threaded groove 42.

[0033] After the staff connects the inner barrel 2 and the mounting groove 11 to each other, the staff only needs to rotate the threaded rod 52 to move the driving plate 51 downward under the action of the threaded rod 52, and then make the driving plate 51 press against the inclined surface 54, so that the slide plate 4 moves toward the direction close to the thickening plate 53 under the action of the driving plate 51 and presses against the thickening plate 53, thereby improving the stability of the inner barrel 2.

[0034] In order to reduce the difficulty for the staff to connect the inner barrel 2 and the mounting groove 11 to each other, and thus reduce the difficulty for the staff to install, a rounded corner is provided at the upper end of the inner wall of the mounting groove 11 to reduce the difficulty for the staff to install the inner barrel 2.

[0035] One end of the stabilizing spring 6 is fixed to the side wall of the slide plate 4, and the other end of the stabilizing spring 6 is fixed to the inner wall of the slide groove 31.
