Description

Technical Field

[0001] The present invention belongs to the technical field of glove box structures, and more particularly, relates to a vacuum glove box. Background Art

[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 known as a glove box, inert gas protection box, or dry box. It is widely used in ultra-pure environments without water, oxygen, or dust, such as those for lithium-ion batteries and materials, semiconductors, supercapacitors, specialty lamps, laser welding, and brazing. It is an ideal device for scientific experiments in universities, research institutes, and corporate laboratories, and is widely used in biochemistry, metallurgy, electronics, chemical engineering, geology, mining, and medicine.

[0003] In the existing technology, vacuum glove boxes (also known as glove boxes) are used in many research and manufacturing fields. Glove boxes not only make it convenient for workers to operate and test scientific objects, but also avoid the need to wear too much protective clothing during experiments, so that experimenters are not hindered by too much protective clothing and their operations are not affected during experiments and research. However, the gloves in the glove box are consumables and need to be replaced after regular use. Currently, most glove boxes only use bolts, rubber pads and other items to seal the gloves and the glove box body after the gloves are replaced. The sealing effect is not good enough and may still cause radiation to harm the health of the experimenters. Summary of the Invention

[0028] The following will clearly and completely describe the technical solutions in the embodiments of the present invention in conjunction with the accompanying drawings. Obviously, the described embodiments are only part of the embodiments of the present invention, not all of them. All other embodiments derived by persons of ordinary skill in the art based on the embodiments of the present invention without inventive effort are also within the scope of protection of the present invention.

[0029] See also Figure 1-7 As shown, an embodiment of the present invention provides a vacuum glove box, including a glove box body 1, a placement table 2 is fixedly connected to the interior of the glove box body 1, a hollow connecting block 3 is fixedly connected to one side of the glove box body 1, a connecting groove 4 is opened between the hollow connecting block 3 and one side of the glove box body 1, a mounting plate 51 is provided on the side of the hollow connecting block 3 away from the glove box body 1, a connecting ring tube 52 is fixedly connected to one side of the mounting plate 51, a glove body 53 is provided on one side of the connecting ring tube 52, and the glove body 53 is arranged on the inner side of the connecting groove 4, and the connecting groove 4 is arranged inside the glove box body 1, a clamping mechanism is provided between the hollow connecting block 3 and the mounting plate 51, and an auxiliary mechanism is provided on the outside of the hollow connecting block 3.

[0030] In a specific embodiment of the present invention, the glove box body 1 can be connected and installed to the placement table 2, and the placement table 2 can be used to place materials or samples that need to be studied and tested. The glove box body 1 can also be installed and connected to the hollow connecting block 3, and the opening of the connecting groove 4 can enable the connecting ring tube 52 to be smoothly placed inside the glove box body 1, thereby realizing the study of the materials or samples placed on the upper side of the placement table 2. The mounting plate 51 can be connected to the glove body 53 through the connecting ring tube 52, and the connecting ring tube 52 can be used stably and smoothly. At the same time, the clamping mechanism can ensure that when the mounting plate 51 is connected to one side of the hollow connecting block 3, the mounting plate 51 can be connected to the hollow connecting block 3 tightly enough, and the air and radiation inside the glove box body 1 are not easy to flow to the outside of the glove box body 1 through the connecting groove 4, causing harm to the experimenter.

[0031] See also Figure 1-7 As shown, the clamping mechanism includes a limiting rod 65 fixedly connected to the side of the hollow connecting block 3 away from the glove box body 1, one side of the hollow connecting block 3 is rotatably connected to the first screw 64, the mounting plate 51 is threadedly connected to the outside of the first screw 64, and the mounting plate 51 is slidably connected to the outside of the limiting rod 65, one side of the glove box body 1 is fixedly connected to a vacuum pump 61, the upper side of the vacuum pump 61 is fixedly connected to a fixed connecting pipe 68, the end of the fixed connecting pipe 68 away from the vacuum pump 61 passes through the hollow connecting block 3, the side of the mounting plate 51 close to the hollow connecting block 3 is fixedly connected to a sealing rubber block 66 and an inflatable sealing rubber strip 63, the lower end of the inflatable sealing rubber strip 63 is fixedly connected to the inflatable pump 62, the sealing rubber block 66 is arranged on the outside of the inflatable sealing rubber strip 63, and a connecting groove 67 is provided on one side of the hollow connecting block 3.

[0032] In a specific embodiment of the present invention, the limiting rod 65 can limit the mounting plate 51. When the mounting plate 51 is installed to the outside of the limiting rod 65, the staff can rotate the first screw 64. At this time, the first screw 64 will limit the mounting plate 51 through the limiting rod 65, driving the mounting plate 51 to move so that it is tightly attached to the hollow connecting block 3. At this time, because the first screw 64 and the mounting plate 51 are threadedly connected, and the threaded connection has a certain self-locking property, it is not easy for the mounting plate 51 to move in the opposite direction due to the reverse rotation of the first screw 64, which is sufficient. The air pump 62 can add air to the inflatable sealing rubber strip 63 by connecting itself to the inflatable sealing rubber strip 63. When the inflatable sealing rubber strip 63 is filled with air, it will expand as the air inside it increases, thereby achieving a seal between the mounting plate 51 and the hollow connecting block 3, making it difficult for external air to flow between the gap between the mounting plate 51 and the hollow connecting block 3. At the same time, the sealing rubber block 66 can also play a certain blocking role against external air, thereby reducing the external air that contacts the inflatable sealing rubber strip 63. The connecting groove 67 can connect the air inside the mounting plate 51 and the hollow connecting block 3. The vacuum pump 61 can discharge the air between the hollow connecting block 3 and the mounting plate 51 by fixing the connecting pipe 68 and the connecting groove 67. At this time, due to the connection and limit of the first screw 64 to the mounting plate 51, the inflatable sealing rubber strip 63 seals the connection between the mounting plate 51 and the hollow connecting block 3, so that the air inside the mounting plate 51 can be discharged smoothly. When enough air is discharged, the air pressure inside the mounting plate 51 and the hollow connecting block 3 will be much lower than the external pressure. At this time, the atmospheric pressure will squeeze the mounting plate 51, so that the mounting plate 51 can be more closely attached to one side of the hollow connecting block 3, thereby achieving the restriction and connection of the mounting plate 51 and reducing the air leakage from the inside of the glove box body 1 to the outside of the glove box body 1. The vacuum pump 61 and the air pump 62 are already existing technologies in modern times, so they will not be described in detail here. Different models of the vacuum pump 61 can be selected according to actual conditions, for example: SY-2000, and different models of the air pump 62 can also be selected according to actual conditions, for example: 1366L1.

[0033] See also Figure 1-7 As shown, the auxiliary mechanism includes a hinge rotating block 71 which is movably hinged to one side of the hollow connecting block 3 through a hinge, and the internal thread of the hinge rotating block 71 is connected to a second screw 72, one end of the second screw 72 is rotatably connected to a limiting pressure holding plate 73, and the limiting pressure holding plate 73 is arranged on the outside of the mounting plate 51, and a limiting mechanism is provided on the side of the limiting pressure holding plate 73 close to the hinge rotating block 71.

[0034] In a specific embodiment of the present invention, the auxiliary mechanism can play an auxiliary role for the first screw 64, so that the air inside the hollow connecting block 3 and the mounting plate 51 can fit more tightly with the hollow connecting block 3 when not being extracted by the vacuum pump 61, and it is not easy to leave a gap. The hollow connecting block 3 can be connected to the hinge rotating block 71 through a hinge shaft, and the hinge rotating block 71 can be connected to the limit pressure holding plate 73 through a second screw 72. At the same time, because the hinge rotating block 71 and the hollow connecting block 3 are connected by a hinge shaft, the hinge rotating block 71 can only rotate at a pitch angle when in use and cannot be flipped. When the second screw rod 72 is rotated, it can move through the threaded connection between itself and the hinge shaft rotating block 71, and at the same time, drive the limiting pressure holding plate 73 to move together. When the limiting pressure holding plate 73 slides to a certain distance, it can be attached to the outside of the mounting plate 51. After that, the staff can continue to rotate the second screw rod 72 so that the limiting pressure holding plate 73 can be more closely fitted with the mounting plate 51 under the rotation of the second screw rod 72, thereby exerting a certain pressure and reinforcement effect on the mounting plate 51, making the connection between the mounting plate 51 and the hollow connecting block 3 tighter.

[0035] See also Figure 1-7 As shown, the limiting mechanism is used to limit the movement of the limiting pressure plate 73. The limiting mechanism includes a fixed slide rod 81 fixedly connected to one side of the limiting pressure plate 73. A hollow groove 82 is provided on one side of the second screw rod 72. The fixed slide rod 81 is arranged inside the hollow groove 82, and the fixed slide rod 81 is slidably connected to the hollow groove 82.

[0036] In a specific embodiment of the present invention, the limiting mechanism can limit the limiting pressure plate 73, so that when the second screw 72 drives the limiting pressure plate 73 to squeeze the mounting plate 51 through its own rotation, the hinge shaft rotation block 71 can limit the fixed slide rod 81 through the hollow groove 82, so that when the limiting pressure plate 73 moves through the rotation of the second screw 72, it can be smoother and more stable, and is not easy to rotate during movement, and is not easy to deviate or shake, etc., thereby increasing the stability of the limiting pressure plate 73 during movement.

[0037] See also Figure 1-7 As shown, a connecting slot 91 is provided on the side of the hollow connecting block 3 away from the glove box body 1, and a connecting block 92 is fixedly connected to the side of the mounting plate 51 close to the hollow connecting block 3. The connecting block 92 is arranged inside the connecting slot 91, and the connecting block 92 is movably connected between the connecting slot 91 and the hollow connecting block 3.

[0038] In a specific embodiment of the present invention, the mounting plate 51 can also install and fix the connecting block 92, and enable the connecting block 92 to be used stably and firmly. After the connecting block 92 is connected to the inside of the connecting slot 91, the hollow connecting block 3 can limit and restrict the connecting block 92 through the connecting slot 91. At the same time, because the connecting block 92 and the mounting plate 51 are fixedly connected, when the connecting block 92 is connected to the hollow connecting block 3 through the connecting slot 91, the hollow connecting block 3 can limit the mounting plate 51 through the connection relationship between the connecting slot 91 and the connecting block 92, so that when the mounting plate 51 is not clamped by the clamping mechanism, the connection and fit between itself and the hollow connecting block 3 is not prone to shaking.

[0039] See also Figure 1-7 As shown, a fixing ring block 11 is fixedly connected to one side of the mounting plate 51 close to the hollow connecting block 3. The fixing ring block 11 is arranged inside the communicating groove 67. The diameter of the fixing ring block 11 is smaller than the diameter of the communicating groove 67, and the fixing ring block 11 is movably plugged into the hollow connecting block 3 through the communicating groove 67.

[0040] In a specific embodiment of the present invention, the mounting plate 51 can connect and fix the fixed ring block 11. After the mounting plate 51 is connected to one side of the hollow connecting block 3 through the first screw 64 and the limit rod 65, the fixed ring block 11 will be inserted into the inside of the communicating groove 67. At this time, the hollow connecting block 3 can limit the fixed ring block 11 and the mounting plate 51 through the communicating groove 67. At the same time, the communicating groove 67 can block the air to a certain extent, so that if the air inside the glove box body 1 leaks, it is not easy to leak quickly through the hollow connecting block 3 to the inside of the mounting plate 51. At the same time, the diameter of the fixed ring block 11 is smaller than the diameter of the communicating groove 67, so that the vacuum pump 61 can smoothly extract the air inside the mounting plate 51 and the hollow connecting block 3 through the fixed communicating pipe 68, and is not easily obstructed by the fixed ring block 11.

[0041] See also Figure 1-7 As shown, a rubber sealing ring block 101 is fixedly connected to the inner side of the hollow connecting block 3, and the rubber sealing ring block 101 is arranged on the outer side of the glove body 53. A threaded connecting ring block 102 is fixedly connected to the inside of the connecting ring tube 52, and the threaded connecting ring block 102 is arranged on the inner side of the glove body 53. A sponge protective block 103 is fixedly connected to the side of the threaded connecting ring block 102 away from the connecting ring tube 52.

[0042] In a specific embodiment of the present invention, the rubber sealing ring block 101 can increase the sealing between the glove body 53 and the hollow connecting block 3, so that the connecting ring tube 52 and the glove body 53 can be sufficiently sealed and stable when in use. The connecting ring tube 52 can be connected to the glove body 53 through the threaded connecting ring block 102, so that the connecting ring tube 52 is threadedly connected to the glove body 53 when connected to each other. Due to the threaded connection, the connection between the connecting ring tube 52 and the glove body 53 can have sufficient stability and tightness, and it is not easy for air to flow to the outside of the glove box body 1 through the connection between the connecting ring tube 52 and the glove body 53. At the same time, the provision of the sponge protective block 103 makes it difficult for the experimenter to injure his hand due to collision with the threaded connecting ring block 102 when putting his hand into the inner side of the connecting ring tube 52, thereby playing a certain protective role for the experimenter's hand.

[0043] See also Figure 1-7 As shown, a mounting groove 121 is opened on one side of the glove box body 1 , and a perspective glass 122 is fixedly connected to the glove box body 1 inside the mounting groove 121 . The perspective glass 122 is used to facilitate observation of the interior of the glove box body 1 .

[0044] In a specific embodiment of the present invention, the glove box body 1 can install and fix the transparent glass 122 through the installation groove 121, so that the transparent glass 122 can be used stably and firmly. The setting of the transparent glass 122 allows the test personnel to observe and record the test objects inside the glove box body 1 from the outside of the glove box body 1 at any time conveniently and simply when not operating the test objects.

[0045] An embodiment of the present invention provides a method for using a vacuum glove box, which specifically includes the following steps:

[0046] When the present invention is in use: the experimenter can place the test object to be used inside the glove box body 1, on the upper side of the placement table 2, and inspect and test the test object after placement. When the experimenter needs to replace or install the connecting ring tube 52 after long-term use, the staff can place the mounting plate 51 to the outside of the first screw 64 and the limit rod 65, and rotate the first screw 64. When the first screw 64 rotates, it will limit the mounting plate 51 through the limit rod 65, and drive the mounting plate 51 to move. When the mounting plate 51 moves to a certain distance, the mounting plate 51 will be tightly fitted with the hollow connecting block 3. At the same time, the connecting block 92 will be inserted into the inside of the connecting slot 91. The hollow connecting block 3 can play a certain limiting role on the mounting plate 51 through the connection between the connecting slot 91 and the connecting block 92.

[0047] When the second locking cam 73 is in the unlocking state, the locking cam 73 is in the unlocking state, and the lock cam 73 is in the unlocking state, and the lock cam 73 is in the unlocking state, and the lock cam 73 is in the unlocking state, and the lock cam 73 is in the unlocking state, and the lock cam 73 is in the unlocking state, and the lock cam 73 is in the unlocking state, and the lock cam 73 is in the unlocking state, and the lock cam 73 is in the unlocking state, and the lock cam 73 is in the unlocking state, and the lock cam 73 is in the unlocking state, and the lock cam 73 is in the unlocking state, and the lock cam 73 is in the unlocking state, and the lock cam 73 is in the unlocking state, and the lock cam 73 is in the unlocking state, and the lock cam 73 is in the unlocking state, and the lock cam 73 is in the unlocking state, and the lock cam 73 is in the unlocking state,

[0048] When the inflatable sealing rubber strip 63 expands to a certain size, it fills and seals the gap between the mounting plate 51 and the hollow connecting block 3. The operator can then stop the inflation pump 62 and start the vacuum pump 61. The vacuum pump 61 will extract the air from the hollow connecting block 3 and the mounting plate 51 through the fixed connecting pipe 68. After a certain amount of air has been expelled from the hollow connecting block 3 and the mounting plate 51, the air pressure inside the mounting plate 51 and the hollow connecting block 3 will be different from the external air pressure and will be lower than the external air pressure. At this time, the external air pressure will press the mounting plate 51, and the mounting plate 51 will be tightly connected and attached to the hollow connecting block 3. This prevents air leakage from the glove box body 1 due to a loose connection between the mounting plate 51 and the hollow connecting block 3. This ensures that after replacing the gloves in the glove box, the gloves can be tightly connected to the box body, preventing gaps from forming. Furthermore, the gloves can be removed from the glove box easily and simply.

[0049] The above description is only a preferred specific embodiment of the present invention, but the scope of protection of the present invention is not limited thereto. Any technician familiar with the technical field can make equivalent replacements or changes based on the technical solutions and improved concepts of the present invention within the technical scope disclosed by the present invention, and these changes should be covered by the scope of protection of the present invention.
