Description

Technical Field

[0001] This utility model relates to the field of vacuum glove box technology, specifically an adjustable dual-position vacuum glove box. Background Technology

[0002] A vacuum glove box is a laboratory device that fills the chamber with high-purity inert gas and circulates it to filter out active substances. It is also called a glove box or inert gas protection chamber. It is widely used in ultra-pure environments that are anhydrous, oxygen-free, and dust-free, such as those used in lithium-ion batteries and materials, semiconductors, supercapacitors, special lamps, laser welding, and brazing.

[0003] In the prior art, such as the adjustable dual-station vacuum glove box structure described in patent number CN221659347U, there is a glove box body and a closed door. The glove box body has two symmetrical adjustment mechanisms inside. Each adjustment mechanism includes an adjustment turntable and a bidirectional lead screw. The outer surface of the bidirectional lead screw is rotatably connected to the inner wall of the glove box body. Two symmetrical sliding plates are threaded onto the outer surface of the bidirectional lead screw. A driven through-hole plate is fixedly connected to the upper surface of each driven through-hole plate. A glove cylinder is installed inside each driven through-hole plate. A connecting pipe is installed on the inner top wall of the glove box body, and a clamp quick-connect flange is installed on the upper surface of the connecting pipe. Through the cooperation between the driven through-hole plates and the adjustment mechanisms, the relative position of the two glove cylinders at a single station can be adjusted. This allows for adjustments to the position of the glove cylinders at a single station for different experimental operators, thus facilitating experiments.

[0004] While the aforementioned patents can adjust the position of the glove cylinder, some problems still exist. The gloves on the glove cylinder are often directly slipped onto it, which results in a lack of fixation. This may cause the gloves to fall off the glove cylinder during use, thus affecting the experiment. In addition, the range of motion of the gloves is limited, and some experimental items inside the glove box may not be accessible, thus affecting the normal conduct of the experiment. Therefore, this utility model provides an adjustable dual-position vacuum glove box. Utility Model Content

[0005] To address the shortcomings of existing technologies, this utility model provides an adjustable dual-position vacuum glove box, which solves the problem that gloves are often directly slipped onto the glove cylinder, resulting in a lack of glove fixation. This can cause the gloves to fall off the glove cylinder during use, affecting the experiment. Additionally, the limited range of glove movement means that some experimental items inside the glove box may not be accessible, thus affecting the normal conduct of the experiment.

[0006] To achieve the above objectives, this utility model is implemented through the following technical solution: an adjustable dual-position vacuum glove box, including a support frame, a glove box body fixedly installed at the top of the support frame, an adjustment component inside the glove box body, and two glove clamping components on the outer wall of the glove box body for clamping and fixing the gloves.

[0007] The adjustment assembly includes two placement trays, each with a rotating shaft fixedly mounted at its bottom end, and both rotating shafts are rotatably connected to the bottom end of the inner wall of the glove box body.

[0008] The glove clamping assembly includes two glove mounting cylinders. An external gear ring and a rotating disk are rotatably mounted on the outer wall of the glove mounting cylinder. The external gear ring and the rotating disk are fixedly connected and used to drive the rotating disk to rotate. A fixed disk is fixedly mounted on the outer wall of the glove mounting cylinder. A set of limiting grooves is opened through the outer wall of the fixed disk. An arc-shaped clamping plate is provided on the inner wall of each set of limiting grooves.

[0009] Preferably, the bottom ends of the two rotating shafts penetrate the bottom end of the glove box body and the bottom end of the support frame, and a worm gear is fixedly installed at the bottom end of each of the two rotating shafts.

[0010] Preferably, a dual-axis motor is fixedly installed at the bottom of the support frame, and worm gears are fixedly installed on both output shafts of the dual-axis motor. The two worm gears are respectively meshed with two worm wheels to drive the worm wheels to rotate.

[0011] Preferably, the outer wall of the rotating disk is provided with a set of arc-shaped grooves, and the inner wall of each set of limiting grooves is slidably connected with a movable slide rod, and the set of movable slide rods is fixedly connected to a set of arc-shaped clamps.

[0012] Preferably, a set of the movable slide rods are movably inserted into the inner wall of the arc-shaped groove, and an electric push rod is fixedly installed on one side of the outer wall of the glove box body. A rack is fixedly installed at the output end of the electric push rod, and the rack is respectively engaged with two external gear rings to drive the external gear rings to rotate.

[0013] Preferably, all four glove mounting cylinders are fixedly connected to the glove box body, and a sealed door is provided on one side of the outer wall of the glove box body.

[0014] Beneficial effects

[0015] This invention provides an adjustable dual-position vacuum glove box. Compared with the prior art, it has the following advantages:

[0016] (1) When the adjustable dual-position vacuum glove box needs to be fixed, the glove opening is first placed on the outer wall of the glove mounting cylinder, and then the electric push rod is turned on. The electric push rod drives the rack to move, and the rack moves in turn, causing the two external gear rings to rotate. The external gear rings are fixedly connected to the rotating disk, so the rotating disk will also rotate. The arc groove on the rotating disk cooperates with the moving slide rod. When the rotating disk rotates, the change in the contour of the arc groove will push the moving slide rod to slide in the limiting slide groove. The moving slide rod is fixedly connected to the arc clamping plate, so that the arc clamping plate will move closer to each other in the limiting slide groove of the fixed disk, thereby clamping and fixing the glove on the glove mounting cylinder. Through the glove clamping component, the glove can be effectively fixed on the glove mounting cylinder, preventing the glove from falling off during use and ensuring the continuity and stability of the experimental operation.

[0017] (2) When an experiment needs to be conducted inside the glove box, the experimental object is first placed on two placement trays. If the object on the placement tray is too far away, the dual-axis motor can be turned on. The dual-axis motor can control the rotation of the worm gears on both sides. Since the worm gear meshes with the worm wheel, the rotation of the worm gear will drive the worm wheel to rotate. During the rotation of the worm wheel, it can drive the rotating shaft and the placement tray to rotate, so that the two placement trays inside the glove box can rotate respectively. This allows the position of the experimental items in the placement trays to be adjusted, making it convenient for the experimenters to take out the experimental items for the experiment, thereby improving work efficiency.

[0025] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0026] This utility model provides two technical solutions:

[0027] Figures 1-6 The first embodiment is shown: an adjustable dual-position vacuum glove box, including a support frame 2, a glove box body 1 fixedly installed on the top of the support frame 2, an adjustment component 3 provided inside the glove box body 1, and two glove clamping components 4 provided on the outer wall of the glove box body 1 for clamping and fixing the gloves.

[0028] The adjustment assembly 3 includes two placement trays 35, and a rotating shaft 34 is fixedly installed at the bottom of each of the two placement trays 35. The two rotating shafts 34 are rotatably connected to the bottom of the inner wall of the glove box body 1. The placement trays 35 can rotate inside the glove box body 1 through the rotating shafts 34.

[0029] The glove clamping assembly 4 includes two glove mounting cylinders 43. An external gear ring 44 and a rotating disk 45 are rotatably mounted on the outer wall of the glove mounting cylinder 43. The external gear ring 44 and the rotating disk 45 are fixedly connected and used to drive the rotating disk 45 to rotate. A fixed disk 48 is fixedly mounted on the outer wall of the glove mounting cylinder 43. A set of limiting grooves 49 are opened through the outer wall of the fixed disk 48. The inner wall of the set of limiting grooves 49 is provided with arc-shaped clamping plates 411.

[0030] The bottom ends of the two rotating shafts 34 pass through the bottom end of the glove box body 1 and the bottom end of the support frame 2. Worm gears 33 are fixedly installed at the bottom ends of the two rotating shafts 34.

[0031] A dual-axis motor 31 is fixedly installed at the bottom of the support frame 2. Both output shafts of the dual-axis motor 31 are fixedly equipped with worm gears 32. The two worm gears 32 are respectively meshed with two worm wheels 33 to drive the worm wheels 33 to rotate. The dual-axis motor 31 is existing technology and can drive the two output shafts to rotate respectively. The output shafts drive the worm gears 32 to rotate, and the worm gears 32 can then drive the worm wheels 33 and the rotating shaft 34 to rotate.

[0032] Figures 1-6 The second embodiment is shown. The main difference from the first embodiment is that: a set of arc-shaped grooves 46 are opened through the outer wall of the rotating disk 45, and a set of limiting slide grooves 49 are slidably connected to the inner wall of each set of sliding rods 410. The sliding rods 410 can move within the limiting slide grooves 49, and the limiting slide grooves 49 can limit the sliding rods 410, ensuring that the sliding rods 410 can only slide in a straight line along the direction of the slide groove, and preventing the sliding rods 410 from falling out of the limiting slide grooves 49. The set of sliding rods 410 are respectively fixedly connected to a set of arc-shaped clamps 411.

[0033] A set of movable slide rods 410 are respectively movably inserted into the inner wall of the arc groove 46. When the arc groove 46 rotates, it can squeeze and drive the movable slide rods 410 to move within the limiting slide groove 49, thereby changing the position of the movable slide rods 410 and the arc clamp 411. An electric push rod 41 is fixedly installed on one side of the outer wall of the glove box body 1. A rack 42 is fixedly installed at the output end of the electric push rod 41. The rack 42 is respectively meshed with two external gear rings 44 to drive the external gear rings 44 to rotate. The electric push rod 41 is existing technology and can drive the rack 42 to move. When the rack 42 moves, it can simultaneously drive the two external gear rings 44 to rotate.

[0034] All four glove mounting cylinders 43 are fixedly connected to the glove box body 1, and the gloves can enter the interior of the glove box body 1 through the glove mounting cylinders 43. A sealed box door 5 is provided on one side of the outer wall of the glove box body 1.

[0035] Furthermore, any content not described in detail in this specification is existing technology known to those skilled in the art.

[0036] During operation, when it is necessary to secure the gloves, first, the glove opening is fitted onto the outer wall of the glove mounting cylinder 43. Then, the electric push rod 41 is activated. The electric push rod 41 drives the rack 42 to move. During the movement of the rack 42, it in turn drives the two outer gear rings 44 to rotate. Since the outer gear rings 44 are fixedly connected to the rotating disk 45, the rotating disk 45 will also rotate accordingly. The arc-shaped groove 46 on the rotating disk 45 cooperates with the moving slide rod 410. When the rotating disk 45 rotates, the change in the contour of the arc-shaped groove 46 will push the moving slide rod 410 to slide within the limiting groove 49. The movable slide bar 410 is fixedly connected to the arc-shaped clamping plate 411, which causes the arc-shaped clamping plate 411 to move closer to each other within the limiting slide groove 49 of the fixed plate 48, thereby clamping and fixing the gloves on the glove mounting cylinder 43. The glove clamping assembly 4 effectively fixes the gloves to the glove mounting cylinder 43, preventing the gloves from easily falling off during use and ensuring the continuity and stability of the experimental operation. When an experiment needs to be conducted inside the glove box body 1, the experimental object is first placed on the two placement trays 35. When the object on the glove box is too far away, the dual-axis motor 31 can be turned on. The dual-axis motor 31 can control the rotation of the worm gears 32 on both sides. Since the worm gears 32 are engaged with the worm wheel 33, the rotation of the worm gears 32 will drive the worm wheel 33 to rotate. During the rotation of the worm wheel 33, it can drive the rotating shaft 34 and the placement tray 35 to rotate, so that the two placement trays 35 in the glove box body 1 can rotate respectively. The position of the experimental items in the placement trays 35 can be adjusted, making it convenient for the experimental personnel to take out the experimental items for experiments, thereby improving work efficiency.
