Technical Field

[0001] The utility model relates to the technical field of quick-change glove structures, in particular to a quick-change glove structure for a vacuum glove box. Background Art

[0002] A vacuum glove box is a type of laboratory equipment primarily used for scientific experiments and production operations in an ultra-pure environment free of water, oxygen, and dust. It provides a high-purity environment by filling a sealed box with high-purity inert gas (such as nitrogen or xenon) and filtering out active substances (such as oxygen, moisture, and organic gases) through a purification system. The gloves on the vacuum glove box need to be replaced after prolonged use. Traditional connection methods often use screw connections, which are slow to dismantle and replace. Traditional replacement methods require the introduction of external air into the vacuum glove box, which destroys the internal vacuum environment. In order to improve this situation, a quick-change glove structure for a vacuum glove box is proposed.

[0003] For example, the quick-change glove structure for a vacuum glove box disclosed in authorization publication number CN219617821U includes a glove box body, a fixing block 1 fixedly connected to the middle portion of the front side of the glove box body, a front side of the fixing block 1 fixedly connected to left and right opposing metal blocks, an inner side wall of the fixing block 1 provided with upper and lower, left and right opposing mounting grooves, and a fixing plate fixedly connected to the middle portion of the front side of the fixing block 1;

[0004] While the operator can press the metal block to expand and contract when installing the glove, the spring 1 then contacts the slot to engage the metal block with the fixing block 2, making it easy for the operator to quickly install and use the glove.

[0005] However, the problem that the existing quick-change glove structure is not conducive to conveniently rotating and quickly changing gloves during use and cannot prevent external air from entering the vacuum box occurs, which increases the replacement time and affects the replacement efficiency. Utility Model Content

[0006] The purpose of the present utility model is to provide a quick-change glove structure for a vacuum glove box, so as to solve the problems in the background art mentioned above, that is, the quick-change glove structure is not convenient for fast and convenient screw-on replacement of gloves, cannot prevent external air from entering the vacuum box, increases replacement time, and affects replacement efficiency.

[0007] To achieve the above-mentioned objectives, the present invention provides the following technical solutions: a quick-change glove structure for a vacuum glove box, comprising a vacuum glove box body and a valve body, the valve body being symmetrically mounted on the outer wall of the vacuum glove box body, and the interior of the valve body being communicated with the interior of the vacuum glove box body, an electric push rod being mounted on the bottom end of the valve body, and the electric push rod being fixedly connected to the valve body, a push arm being mounted on the output end of the electric push rod, a valve plate being provided inside the valve body, and the valve plate being slidingly connected to the valve body, and the push arm being connected to the valve plate, an outer load-bearing ring being mounted on one side of the valve body, and the outer load-bearing ring being fixedly connected to the valve body, an inner load-bearing ring being provided inside the outer load-bearing ring, and the inner load-bearing ring being fixedly connected to the outer load-bearing ring, and an interlayer being provided between the inner load-bearing ring and the outer load-bearing ring.

[0008] Preferably, a limiting ring is provided inside each of the interlayers, and the limiting ring is slidably connected to the outer bearing ring and the inner bearing ring.

[0009] Preferably, multiple groups of springs with equal spacing are installed on one side of the limiting ring, and the springs are connected to the outer bearing ring.

[0010] Preferably, a sealing ring is provided at each port position on one side of the inner bearing ring, and the sealing ring is slidably connected to the inner bearing ring.

[0011] Preferably, a plurality of groups of vertical grooves with equal intervals are installed on the inner wall of the outer bearing ring, and a transverse groove is installed on the inner wall of the outer bearing ring on one side of the push arm, and the vertical grooves are connected to the transverse grooves.

[0012] Preferably, a connecting ring is provided on the outside of the outer bearing ring, and a trapezoidal tube is installed on one end of the connecting ring away from the outer bearing ring, and the trapezoidal tube is fixedly connected to the connecting ring.

[0013] Preferably, multiple groups of limit blocks with equal intervals are installed on the outer wall of the connecting ring, and the limit blocks are fixedly connected to the connecting ring.

[0014] Preferably, the limit block is slidably connected to the vertical slot, and the limit block is slidably connected to the horizontal slot.

[0015] Compared with the prior art, the beneficial effects of the present invention are: the quick-change glove structure not only realizes the convenient screw-on quick change of gloves, avoids the external air from entering the vacuum box, reduces the waste of time, but also improves the efficiency of replacement;

[0016] (1) When the gloves on the vacuum glove box body need to be replaced, the electric push rod drives the push arm to move, and the push arm drives the valve plate to move inside the valve body, so that the valve plate blocks the outer bearing ring, thereby preventing external air from entering the interior of the vacuum glove box body, preventing the vacuum inside the vacuum glove box body from being evacuated again, and reducing time waste;

[0017] (2) After the outer load ring is sealed, the gloves are connected to the trapezoidal tube. After removing the connecting ring and the trapezoidal tube and replacing the gloves with new ones, the sealing ring is put on the port surface of the inner load ring, the connecting ring is taken, the connecting ring is aligned with the interlayer, and the connecting ring is pressed to the inside of the interlayer. The connecting ring drives the limit ring to move and the limit ring squeezes the spring. At the same time, the connecting ring drives the limit block to move inside the vertical groove. When the limit block moves to the horizontal groove position, the connecting ring is rotated. The connecting ring drives the limit block to rotate inside the horizontal groove. Under the elastic support of the spring, the connecting ring is stuck inside the interlayer. At the same time, the inner wall of the trapezoidal tube is tightly attached to the sealing ring. Because the trapezoidal tube is a trapezoidal design, the inner wall of the trapezoidal tube and the sealing ring are more tightly attached, thereby providing a sealed environment to prevent external air from entering the interior of the vacuum glove box body. Then, the electric push rod is closed, and the electric push rod drives the valve plate to reset, and the vacuum glove box body is restored to a usable state, thereby completing the quick replacement of gloves.

An inner load ring 8 is disposed inside the outer load ring 3, and the inner load ring 8 is fixedly connected to the outer load ring 3, and an interlayer 9 is disposed between the inner load ring 8 and the outer load ring 3.

[0027] When the gloves on the vacuum glove box body 1 need to be replaced, the electric push rod 7 is first opened, and the electric push rod 7 drives the push arm 6 to move, and the push arm 6 drives the valve plate 5 to move inside the valve body 2, so that the valve plate 5 blocks the outer carrying ring 3, thereby preventing external air from entering the vacuum glove box body 1, preventing the vacuum inside the vacuum glove box body 1 from being evacuated again, and reducing time waste;

[0028] A limit ring 11 is provided inside each interlayer 9, and the limit ring 11 is slidably connected to the outer load ring 3 and the inner load ring 8. Multiple sets of springs 10 with equal spacing are installed on one side of the limit ring 11, and the springs 10 are connected to the outer load ring 3;

[0029] A sealing ring 12 is provided at each port position on one side of the inner load ring 8, and the sealing ring 12 is slidably connected to the inner load ring 8;

[0030] The inner wall of the outer load-bearing ring 3 is provided with multiple sets of vertical grooves 16 at equal intervals. The inner wall of the outer load-bearing ring 3 on one side of the push arm 6 is provided with a horizontal groove 15, and the vertical grooves 16 are connected to the horizontal grooves 15. The outer side of the outer load-bearing ring 3 is provided with a connecting ring 4.

[0032] After the outer load-bearing ring 3 is blocked, since the gloves are connected to the trapezoidal tube 14, the connecting ring 4 and the trapezoidal tube 14 are removed and replaced with new gloves, the sealing ring 12 is put on the port surface of the inner load-bearing ring 8, the connecting ring 4 is taken out, the connecting ring 4 is aligned with the interlayer 9, the connecting ring 4 is pressed, and the connecting ring 4 is pressed into the inside of the interlayer 9, and the limiting ring 11 is driven by the connecting ring 4 to move and the limiting ring 11 squeezes the spring 10, and at the same time, the limiting block 13 is driven by the connecting ring 4 to move inside the vertical groove 16, and when the limiting block 13 moves to the position of the horizontal groove 15, the connecting ring 4 is rotated, and the limiting block 13 is driven by the connecting ring 4 to move in the horizontal groove 15 The inner ring 4 is rotated and, with the elastic support of the spring 10, is clamped inside the interlayer 9. At the same time, the inner wall of the trapezoidal tube 14 is in close contact with the sealing ring 12. Since the trapezoidal tube 14 is a trapezoidal design, the inner wall of the trapezoidal tube 14 and the sealing ring 12 fit more closely to provide a sealed environment to prevent external air from entering the interior of the vacuum glove box body 1. Then, the electric push rod 7 is closed, and the electric push rod 7 drives the valve plate 5 to reset, restoring the vacuum glove box body 1 to a usable state, thereby completing the quick replacement of gloves. The above is all the usage content of the quick-change glove structure of the vacuum glove box.

[0033] Working principle: When the gloves on the vacuum glove box body 1 need to be replaced, the electric push rod 7 drives the push arm 6 to move, and the push arm 6 drives the valve plate 5 to move inside the valve body 2, so that the valve plate 5 blocks the outer load-bearing ring 3, thereby preventing external air from entering the interior of the vacuum glove box body 1, preventing the vacuum inside the vacuum glove box body 1 from being evacuated again, and reducing time waste. When the outer load-bearing ring 3 is sealed, because the gloves are connected to the trapezoidal tube 14, the connecting ring 4 and the trapezoidal tube 14 are removed and replaced with new gloves, the sealing ring 12 is put on the port surface of the inner load-bearing ring 8, the connecting ring 4 is taken out, and the connecting ring 4 is aligned with the interlayer 9, and the connecting ring 4 is pressed and pressed into the inside of the interlayer 9. The limiting ring 11 is driven by the connecting ring 4 to move and the limiting ring 11 squeezes the spring 10.

With the elastic support of the spring 10, the connecting ring 4 is stuck inside the interlayer 9. At the same time, the inner wall of the trapezoidal tube 14 is tightly attached to the sealing ring 12. Because the trapezoidal tube 14 is a trapezoidal design, the inner wall of the trapezoidal tube 14 fits more closely with the sealing ring 12, thereby providing a sealed environment to prevent external air from entering the interior of the vacuum glove box body 1. Then, the electric push rod 7 is closed, and the electric push rod 7 drives the valve plate 5 to reset, restoring the vacuum glove box body 1 to a usable state to complete the quick replacement of gloves. The above is all the usage content of the quick-change glove structure of the vacuum glove box.
