Description

Technical Field

[0001] This invention belongs to the field of glove box structural design technology, specifically relating to a glove sealing structure for a glove box. Background Technology

[0002] Vacuum glove boxes, also known simply as glove boxes, are commonly used devices that provide such sealed spaces and environments. They are widely used in factories, laboratories, and analytical rooms. By filling them with high-purity inert gas and circulating and filtering out reactive substances such as oxygen and moisture, materials can be safely placed in and taken out, and operations, reactions, and tests can be carried out freely in an oxygen-free and water-free environment.

[0003] Currently, gloves in glove boxes are considered consumables and need to be replaced periodically. After replacement, the gloves are typically sealed to the glove box body using bolts, rubber gaskets, etc. However, after use, laboratory personnel (or operators) usually let the gloves hang down or tuck them inside the glove box. This allows outside air to seep into the glove box through gaps in the gloves or their connections, affecting the internal environment and potentially causing adverse reactions such as oxidation of the products. Summary of the Invention

[0004] The purpose of this invention is to overcome the shortcomings of the prior art and provide a glove sealing structure for a glove box.

[0005] To achieve the above objectives, the present invention provides the following technical solution:

[0006] A glove sealing structure for a glove box includes a glove box body. Glove openings are provided on both sides of the front panel of the glove box body. A connecting ring is provided inside the glove opening. A glove is fixedly connected to the rear end of the connecting ring. A cover plate is fixedly connected to the front end of the connecting ring. A sealing mechanism and an installation mechanism are provided on the front side of the glove box body.

[0007] The sealing mechanism includes a sealing ring fixedly connected to the front side of the glove opening. The outer ring surface of the sealing ring is provided with a first annular groove. A first air bladder is fixedly connected inside the first annular groove. A connecting tube is fixedly connected to both ends of the first air bladder. A second air bladder is fixedly connected to the ends of the two connecting tubes. A second annular groove is provided on the side of the cover plate near the sealing ring. The outer diameter of the second annular groove is the same as the outer ring surface diameter of the sealing ring.

[0008] As a preferred embodiment, the mounting mechanism includes a mounting block fixedly connected to the top of the cover plate. The mounting block has a horizontal groove on the side near the glove box body, and each top of the mounting block has a sliding hole that communicates with the horizontal groove.

[0009] In a preferred embodiment, a sliding plate is slidably connected inside each sliding hole, and a locking block is fixedly connected to the bottom end of each sliding plate.

[0010] As a preferred embodiment, both ends of the front side of the glove box body are fixedly connected to connecting rods, and the front ends of the connecting rods are fixedly connected to blocks, with slots provided at the top of the blocks.

[0011] As a preferred embodiment, a limiting groove is provided on one side of each sliding hole, and a limiting block is fixedly connected to the bottom end of the side of the sliding plate, with the limiting block located in the limiting groove and slidably connected thereto.

[0012] In a preferred embodiment, each of the mounting blocks is fixedly connected to an L-shaped plate at its top, and each of the sliding plates is rotatably connected to an L-shaped rod at its top.

[0013] As a preferred embodiment, the rear side of the cover plate is provided with a third annular groove, and the two ends of the front side of the glove box body are fixedly connected with annular plates, and the inner and outer ring diameters of the annular plates are the same as the inner and outer diameters of the third annular groove.

[0014] As a preferred embodiment, a set of positioning plates is fixedly connected to both ends of the front side of the glove box body, and the number of positioning plates in each set is two.

[0015] As a preferred embodiment, the glove box body has an observation opening on the front side, and an observation window is fixedly connected inside the observation opening.

[0016] Compared with the prior art, the present invention has the following beneficial effects:

[0017] (1) The glove sealing structure of the glove box of the present invention squeezes the second air bladder by the cover plate, so that the gas inside the second air bladder enters the first air bladder, the first air bladder inflates, the first air bladder opens the sealing ring, and the outer wall of the sealing ring fits tightly with the connecting ring and the glove opening, which helps to increase the sealing of the glove opening, prevent air from flowing in, affecting the internal environment of the glove box body, and thus causing adverse reactions such as oxidation of the product.

[0018] (2) The glove sealing structure of the glove box of the present invention allows the block to enter the horizontal groove by pulling up the sliding plate until it is tightly fitted with the inner side wall of the horizontal groove. When the sliding plate is released, the block is inserted into the corresponding slot, thereby realizing the installation and fixing of the glove. This structure is easy to disassemble and greatly improves the convenience of glove installation in the glove box. Attached Figure Description

[0026] The technical solutions of the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of the present invention.

[0027] Please see 1 and Figure 2 As shown, this embodiment of the invention provides a glove sealing structure for a glove box, specifically including a glove box body 1. Glove openings 2 are provided on both sides of the front panel of the glove box body 1. An observation opening 15 is provided on the front side of the glove box body 1, and an observation window 16 is fixedly connected inside the observation opening 15. The design of the observation window 16 facilitates observation of the interior of the glove box body 1. Connecting rings 3 are provided inside each glove opening 2. Gloves 4 are fixedly connected to the rear end of each connecting ring 3, and a cover plate 5 is fixedly connected to the front end of each connecting ring 3. A sealing mechanism 6 and an installation mechanism 7 are provided on the front side of the glove box body 1.

[0028] Please refer to Figure 3. The sealing mechanism 6 specifically includes a sealing ring 61 fixedly connected to the front side of the glove opening 2. The outer ring surface of the sealing ring 61 is provided with a first annular groove 62. A first airbag 63 is fixedly connected inside the first annular groove 62. Both ends of the first airbag 63 are fixedly connected with connecting tubes 64. The ends of the two connecting tubes 64 are fixedly connected with second airbags 65. The cover plate 5 is provided with a second annular groove 66 on the side near the sealing ring 61. The outer diameter of the second annular groove 66 is the same as the outer annular diameter of the sealing ring 61. The rear side of the cover plate 5 is provided with a third annular groove 12. Both ends of the front side of the glove box body 1 are fixedly connected with annular plates 13. The inner and outer ring diameters of the annular plates 13 are the same as the inner and outer diameters of the third annular groove 12. The design of the annular plates 13 ensures that the second airbag 65 will not be pulled when it is squeezed. After being squeezed, the annular plates 13 and the inner side of the third annular groove 12 are in close contact, and the second airbag 65 is located between the two, which avoids the second airbag 65 being pulled and thus causing damage to the second airbag 65.

[0029] During operation, gloves 4 are inserted into the glove box body 1 through the glove opening 2, and the connecting ring 3 enters the glove opening 2. At this time, the cover plate 5 compresses the second air bladder 65, and the gas inside the second air bladder 65 enters the first air bladder 63 through the connecting pipe 64. The second annular groove 66 gradually comes into contact with the outer ring surface of the sealing ring 61. As the gas inside the first air bladder 63 increases, the first air bladder 63 inflates, gradually expanding the sealing ring 61, so that the outer wall of the sealing ring 61 fits tightly with the connecting ring 3 and the glove opening 2, improving the sealing effect. Furthermore, this structure, through the compression of the second air bladder 65 by the cover plate 5, allows the gas inside the second air bladder 65 to enter the first air bladder 63, causing the first air bladder 63 to inflate. The first air bladder 63 expands the sealing ring 61, and the outer wall of the sealing ring 61 fits tightly with the connecting ring 3 and the glove opening 2, which helps to increase the sealing at the glove opening 2, preventing air from flowing in and affecting the internal environment of the glove box body 1, thereby causing adverse reactions such as oxidation of the product.

[0030] Please see Figure 4 and Figure 5As shown, the mounting mechanism 7 includes a mounting block 71 fixedly connected to the top of the cover plate 5. A transverse groove 72 is provided on the side of the mounting block 71 near the glove box body 1. Each mounting block 71 has a sliding hole 73 at its top, which communicates with the transverse groove 72. A sliding plate 74 is slidably connected within each sliding hole 73. A locking block 75 is fixedly connected to the bottom of each sliding plate 74. Connecting rods 76 are fixedly connected to both ends of the front side of the glove box body 1. A square block 77 is fixedly connected to the front end of each connecting rod 76, and a locking groove 78 is provided at the top of each square block 77. A limiting groove 8 is provided on one side of each sliding hole 73. A limiting block 9 is fixedly connected to the bottom of the side of the sliding plate 74, and the limiting block 9 is located within and slidably connected to the limiting groove 8. The design of the limiting groove 8 and the limiting block 9 limits the movement of the sliding plate 74, preventing the sliding plate 74 from disengaging from the sliding hole 73.

[0031] Please see Figure 4 and Figure 5 As shown, each mounting block 71 has an L-shaped plate 10 fixedly connected to its top, and each sliding plate 74 has an L-shaped rod 11 rotatably connected to its top. Before installing or removing the glove 4, pull the L-shaped rod 11 upwards and rotate it so that its horizontal end is at the top of the horizontal end of the L-shaped plate 10 and supported by it, thus facilitating the installation and removal of the glove 4. A set of positioning plates 14 is fixedly connected to both ends of the front side of the glove box body 1, and each set of positioning plates 14 consists of two plates. The design of the positioning plates 14 ensures that the square block 77 can be aligned with the transverse groove 72 during installation.

[0032] During operation, as the cover plate 5 is installed, it moves the mounting block 71. At this time, pulling the sliding plate 74 upwards causes the locking block 75 to move upwards and disengage from the transverse groove 72. Then, the square block 77 gradually enters the transverse groove 72 until it is tightly fitted against the inner wall of the groove. Releasing the sliding plate 74 allows it to slide downwards under gravity, moving the locking block 75 downwards. The locking block 75 then engages in the corresponding slot 78, thus securing the cover plate 5 and fixing the glove 4. Furthermore, this structure, by pulling the sliding plate 74 upwards, causes the square block 77 to enter the transverse groove 72 until it is tightly fitted against the inner wall of the groove. Releasing the sliding plate 74 allows the locking block 75 to engage in the corresponding slot 78, thereby securing the glove 4.

[0033] Working Principle: During operation, the glove 4 is inserted into the glove box body 1 through the glove opening 2, and the connecting ring 3 enters the glove opening 2. At this time, the cover plate 5 compresses the second airbag 65, and the gas inside the second airbag 65 enters the first airbag 63 through the connecting pipe 64. The second annular groove 66 gradually comes into contact with the outer ring surface of the sealing ring 61. As the gas inside the first airbag 63 increases, the first airbag 63 inflates, gradually expanding the sealing ring 61, so that the outer wall of the sealing ring 61 fits tightly with the connecting ring 3 and the glove opening 2, improving the sealing effect. Furthermore, this structure, through the compression of the second airbag 65 by the cover plate 5, allows the gas inside the second airbag 65 to enter the first airbag 63, causing the first airbag 63 to inflate. The first airbag 63 expands the sealing ring 61, and the outer wall of the sealing ring 61 fits tightly with the connecting ring 3 and the glove opening 2, which helps to increase the sealing of the glove opening 2, preventing air from flowing in and affecting the internal environment of the glove box body 1, thereby causing adverse reactions such as oxidation of the product.

[0034] It will be apparent to those skilled in the art that the present invention is not limited to the details of the exemplary embodiments described above, and that the invention can be implemented in other specific forms without departing from its spirit or essential characteristics.
