[0026] See also Figure 1-4The utility model provides a technical solution for the glove opening structure of a vacuum glove box: it includes a glove box body 1, and symmetrically provided with through-type annular notches 101 on the front outer wall of the glove box body 1, and fixed sleeves 102 are fixedly connected to the inner sides of the two groups of annular notches 101, and the upper and lower ends of the outer peripheral side walls of the two fixed sleeves 102 are provided with through-type card grooves 103, and the front outer wall of the glove box body 1 is symmetrically provided with a connecting component 2 at the fixed sleeve 102, and the connecting component 2 includes two fixed joints 201, and the interior of the two fixed sleeves 102 is provided with a connecting sleeve 202, one end of the two connecting sleeves 202 passes through the fixing sleeve 102 and extends to the interior of the glove box body 1 and is fixedly connected to the two glove bodies, while the other ends of the two connecting sleeves 202 are in contact with one end of the two fixing joints 201 extending into the interior of the fixing sleeve 102, and the inner ends of the two fixing joints 201 are in contact with each other. Blocks 203 that match the slots 103 are fixedly installed at the upper and lower ends of the side wall, and the block 203 is clamped in the inner side of the slot 103. First threaded holes 204 are symmetrically opened on the outer walls of the two fixing joints 201, and second threaded holes 205 that match the first threaded holes 204 are symmetrically opened on the outer walls of the two connecting sleeves 202. The inner sides of the first threaded holes 204 and the second threaded holes 205 are fixedly connected to the fixing joints 201 and the connecting sleeves 202 by adjusting studs 206 that are threaded together. Two glove bodies are symmetrically provided on the inner wall of the glove box body 1 and corresponding to the fixed sleeves 102. The two glove bodies are fixedly connected to the connecting assembly 2. First sealing rings 4 are fixedly installed on the inner walls of the two fixing sleeves 102. The outer walls of the two fixing sleeves are tightly fitted with the two first sealing rings 4. Second sealing rings 401 are fixedly installed on the outer surfaces of the two fixing joints 201. The fixing joint 201 is twisted to rotate the block 203 and separate it from the slot 103. Then, the fixing joint 201 is pulled to drive the connecting sleeve 202 and the glove body to move along the inner side of the fixing sleeve 102 and be removed. Then, the adjusting screw 206 is twisted to disengage it from the first threaded hole 204 and the second threaded hole 205. Then, the connecting sleeve 202 can be separated from the glove body and replaced, which reduces the difficulty of replacement for the operator and improves the efficiency of replacement, thereby increasing the practicality of the glove opening structure of the vacuum glove box. Later, when reinstalling, the operation is reversed. After the glove body is placed into the interior of the glove box body 1, the block 203 is aligned with the slot 103. At this time, the fixing joint 201 is rotated to drive the block 203 to be reinserted into the slot 103, and the fixing joint 201 and the connecting sleeve 202 are respectively squeezed by the first sealing ring 4 and the second sealing ring 401, thereby improving the overall sealing of the structure.

[0027] A limiting assembly 3 for fixing the connecting assembly 2 is symmetrically provided on the front outer wall of the glove box body 1. The limiting assembly 3 includes a fixing frame 301 symmetrically installed on the front outer wall of the glove box body 1 and located below the two fixing joints 201. A through-type sliding groove 302 is provided on the inner side walls corresponding to the two sides of the two fixing frames 301. A stabilizing plate 303 is slidably connected to the interior of the fixing frame 301. A limiting groove 304 is provided on the outer peripheral side walls of the two fixing joints 201 and corresponding to the fixing frame 301. The outer top surfaces of the two stabilizing plates 303 are fixed. A limiting plate 305 is installed that is compatible with the limiting groove 304. One end of the two limiting plates 305 extends through the fixed frame 301 and is inserted into the inner side of the limiting groove 304. Guide blocks 306 are fixedly installed on the corresponding outer walls on both sides of the two stabilizing plates 303. The guide blocks 306 slide in the inner sides of the two sliding grooves 302. At the same time, threaded rods 307 are rotatably installed on the outer bottom surfaces of the two stabilizing plates 303. One end of the two threaded rods 307 extends through the fixed frame 301 to the outer bottom surface of the fixed frame 301, and a knob is also fixedly installed on the outer peripheral side wall. By twisting the threaded rod 307 and assisting the guide block 306 to slide on the inner side of the sliding groove 302, the stabilizing plate 303 is stably driven to move back and forth along the inside of the fixed frame 301, and then the limiting plate 305 can be quickly and firmly inserted into the inside of the limiting groove 304, thereby limiting the fixed joint 201 and improving the overall stability of the glove opening structure. When the fixed joint 201 needs to be disassembled, the reverse operation can be performed to pull the limiting plate 305 out from the inner side of the limiting groove 304, thereby facilitating the release of the limiting fixation of the fixed joint 201 and facilitating the subsequent removal of the fixed joint 201.

[0028] The working principle of the present invention is as follows: when in use, first screw the threaded rod 307 to drive the stabilizing plate 303 to move downward in the fixing frame 301, and at the same time, let the limiting plate 305 slide out from the inside of the limiting groove 304, so that the limiting fixation of the fixed joint 201 can be quickly released.

[0029] At the same time, the fixing joint 201 is twisted to make the clamping block 203 rotate inside the clamping groove 103 and separate from it, so that the fixing joint 201 and the fixing sleeve 102 can be separated from each other. Then, the fixing joint 201 is pulled to drive the connecting sleeve 202 and the glove body to move along the inner side of the fixing sleeve 102 and be removed. Then, the adjusting screw 206 is twisted to disengage it from the first threaded hole 204 and the second threaded hole 205, and the connecting sleeve 202 can be separated from the glove body and replaced. This reduces the difficulty of replacement for the operator and improves the efficiency of replacement, thereby increasing the practicality of the glove port structure of the vacuum glove box.

[0030] At the same time, when reinstalling, perform the reverse operation. After placing the glove body into the interior of the glove box body 1, align the block 203 with the slot 103. At this time, rotate the fixing joint 201 to drive the block 203 to be reinserted into the slot 103. Then, let the fixing joint 201 and the connecting sleeve 202 squeeze the first sealing ring 4 and the second sealing ring 401 respectively, thereby improving the overall sealing of the structure.

[0031] Finally, the threaded rod 307 is screwed to drive the stabilizing plate 303 to move upward in the fixing frame 301 , and while moving upward, the limiting plate 305 is re-inserted stably into the limiting groove 304 , thereby limiting and fixing the fixed joint 201 .

[0032] The above description is merely a preferred embodiment of the present invention. It should be noted that those skilled in the art may make various improvements and modifications without departing from the principles of the present invention, and such improvements and modifications should be considered within the scope of protection of the present invention. Structures, devices, and operating methods not specifically described or explained in this invention shall, unless otherwise specified or limited, be implemented in accordance with conventional means in the art.
