Description

Technical Field

[0001] This utility model belongs to the field of glove box technology and relates to a structure for an internal placement platform in a glove box. Background Technology

[0002] A glove box is a sealed working space formed by the box body and a gas purification system. The gas purification system continuously draws in and purifies the gas inside the box, so that the inside of the box always maintains a high-cleanliness and high-purity inert gas environment, thereby providing a special environment for experiments to be carried out, so as to complete many experiments and production that cannot be carried out under conventional conditions.

[0003] For example, a Chinese patent with application number 2023227845326 discloses a glove box built-in placement platform structure and glove box, including a base plate and a placement plate. A drive cylinder is fixedly installed on the top of the base plate, and a support plate is fixedly connected to the telescopic end of the drive cylinder. A limit groove is opened inside the support plate. An adjustment mechanism is provided on the top of the support plate. A set of support mechanisms is provided on the top of the support plate. A connecting column is fixedly connected to the bottom surface of the placement plate. An auxiliary plate is hinged to both the left and right sides of the placement plate. Although this technical solution can adjust the overall area of ​​the placement plate, when a sample is placed on the placement plate, the rotation of the gear can easily cause the sample to deviate from the placement plate, which may interfere with the inner wall of the glove box or other internal components, thus causing the limitation of this technical solution.

A retaining ring is provided in the annular groove. At least two first springs are provided at equal intervals at the lower end of the retaining ring. The lower end of each first spring is connected to the bottom of the annular groove.

[0006] Preferably, the retaining ring and the annular groove are slidably connected, and the upper outer wall of the retaining ring is inclined to form a slope.

[0007] Preferably, a placement plate is fixedly provided at the upper end of the rotating shaft. The placement plate is annular, and there is a distance between the outer ring surface of the placement plate and the inner ring surface of the support ring.

Therefore, they should not be construed as limitations on this utility model.

[0021] like Figure 1-4 As shown, this utility model is a glove box built-in platform structure, including a base plate 1 and a rotating shaft 24. The rotating shaft 24 is provided with three support rods 3. The upper end of the support rods 3 is provided with a support ring 31. The support ring 31 is provided with an annular groove 34. A retaining ring 32 is provided in the annular groove 34. At least two first springs 33 are provided at equal intervals at the lower end of the retaining ring 32. The lower end of each first spring 33 is connected to the bottom of the annular groove 34. The base plate 1 is installed on a bracket inside the glove box.

[0022] Three support rods 3 on the rotating shaft 24 are used to support and fix the entire device to ensure its stability; the support ring 31, which is fixed together at the upper end of the support rods 3, provides an annular support surface for supporting the sample; when the sample is placed on the placement plate 4, the retaining ring 32 can prevent the sample from deviating from the placement plate 4 due to external force or slight vibration, thereby ensuring the stability of the sample on the placement plate 4; so that the sample will not deviate from the support ring 31 and the placement plate 4.

[0023] The first spring 33 is designed to ensure that when the sample is pushed onto the placement plate 4, the retaining ring 32 compresses the first spring 33, so that the upper end of the retaining ring 32 and the upper end of the support ring 31 are on the same plane, thus quickly pushing the sample onto the placement plate 4.

[0024] Preferably, the retaining ring 32 and the annular groove 34 are slidably connected, and the upper outer wall of the retaining ring 32 is inclined to form a slope, which facilitates the compression of the retaining ring 32 when the sample is pushed.

[0025] Preferably, a placement plate 4 is fixedly provided at the upper end of the rotating shaft 24. The placement plate 4 is annular, and there is a distance between the outer ring surface of the placement plate 4 and the inner ring surface of the support ring 31. A retractable baffle 43 is provided at the distance.

[0026] The baffle 43 is arc-shaped, and at least two second springs 42 are provided at the lower end of the baffle 43. The lower ends of the second springs 42 are all provided with a fixing plate 41, which is fixedly sleeved on the outside of the rotating shaft 24.

[0027] The baffle 43 is located directly in front of the support ring 31, so that the sample is in contact with the baffle 43 when it is placed, ensuring that the sample can be placed on the placement plate 4.

[0028] Preferably, a support plate 12 is rotatably provided at the lower end of the rotating shaft 24, and a motor 21 is mounted on the support plate 12 via a motor support plate 2. A first gear 22 is provided at the output end of the motor 21, and a second gear 23 sleeved on the outside of the rotating shaft 24 meshes with the outer side of the first gear 22.
