Description

Technical Field

[0001] This invention belongs to the field of glove box glove detection technology, and specifically relates to a glove box glove detection device. 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 primarily used for the removal of O2, H2O, and organic gases. 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. This product is an ideal device for scientific experiments in universities, research institutions, and corporate laboratories, and is widely used in biochemistry, metallurgy, electronics, chemical engineering, geology, mining, and pharmaceutical industries.

[0003] Currently, the rubber gloves in glove boxes are considered consumable parts and need frequent replacement. However, before replacement, it is necessary to check whether the rubber gloves are damaged. If the gloves are damaged, outside oxygen can enter the glove box through the damaged part, which will disrupt the internal environment of the glove box and affect the experiment. To address this issue, our company has designed a glove detection device for glove boxes to solve the above-mentioned technical problems. Summary of the Invention

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

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

[0006] A glove box glove detection device includes a glove box body, a bottom box fixedly connected to the bottom end of the glove box body, an observation window fixedly connected to the top of the front side of the glove box body, glove openings at both ends of the front side of the glove box body, and a detection mechanism provided on the front side of the glove box body.

[0007] The testing mechanism includes blowers fixedly connected to both sides of the bottom of the bottom box. Each blower has a telescopic pipe fixedly connected to its air outlet. Each telescopic pipe has a sealing plate fixedly connected to its top end. Each sealing plate has an air inlet on its surface. Each of the two ends of the front side of the glove box body has a set of slots. Each set of slots is circumferentially opened on the outside of the glove opening. Each glove opening near the slot has a set of inserts fixedly connected circumferentially.

[0008] As a preferred embodiment, the front side of the glove box body is provided with an anti-drop mechanism; the anti-drop mechanism includes cylinders on both sides of the glove opening, the rear ends of the cylinders are fixedly connected to the glove box body, the front ends of the cylinders are rotatably connected to a rotating column, and the outer sides of the cylinders are fitted with springs, the rear ends of the springs are fixedly connected to the glove box body.

[0009] As a preferred embodiment, the rear ends of both sides of the rotating column are fixedly connected with abutments, and the two ends of the sealing disc are fixedly connected with connecting ears.

[0010] As a preferred embodiment, the surface of each connecting ear is provided with a circular opening, and through openings are provided on both sides of the circular opening.

[0011] As a preferred embodiment, both ends of the front side of the base box are hinged with sealing doors, and handles are fixedly connected to the outer sides of the sealing doors.

[0012] As a preferred embodiment, a fixing plate is fixedly connected inside the base box, and the top end of the telescopic tube extends to the top of the fixing plate.

[0013] In a preferred embodiment, the diameter of the cylinder is the same as the diameter of the rotating column, and the diameter of the rotating column is the same as the diameter of the circular opening.

[0014] As a preferred embodiment, the bottom box is provided with guide rollers, and both ends of the guide rollers are rotatably connected to the two sides inside the bottom box.

[0015] As a preferred embodiment, a sealing gasket is fixedly connected to the rear side of each sealing disc, and the diameter of the sealing gasket is larger than the diameter of the glove opening.

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

[0017] (1) The present invention inserts the plug forcefully into the slot so that the sealing plate and the glove box body fit tightly together, avoiding the glove opening. The blower is used to supply air to the glove opening through the telescopic tube to open it. Then, the glove is judged to be intact by observing whether the glove collapses. The interference fit between the plug and the slot helps to avoid excessive pressure inside the glove, which would cause the sealing plate to separate from the glove box body.

[0018] (2) In this invention, the rotating column is inserted into the round opening and the spring is squeezed. When the abutment just passes through the opening, the sealing disc is tightly fitted with the side of the glove box body. When the rotating column is rotated, the rotating column drives the abutment to be misaligned with the opening. At this time, the abutment fixes the sealing disc, which prevents the internal air pressure from being too high after the glove is inflated, thus avoiding the situation where the sealing disc is squeezed outward. This ensures the sealing performance of the sealing disc at the glove opening. Attached Figure Description

[0025] 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.

[0026] Please see Figures 1 to 4 As shown, this embodiment of the invention provides a glove detection device for a glove box, including a glove box body 1, with a bottom box 2 fixedly connected to the bottom end of the glove box body 1. Sealing doors 7 are hinged to both ends of the front side of the bottom box 2, and handles 8 are fixedly connected to the outer sides of the sealing doors 7. When the device is not in use, the sealing doors 7 seal the bottom box 2 to prevent external dust from entering. An observation window 3 is fixedly connected to the top of the front side of the glove box body 1, and glove openings 4 are provided at both ends of the front side of the glove box body 1. A detection mechanism 5 and an anti-drop mechanism 6 are respectively provided on the front side of the glove box body 1.

[0027] Please see Figures 2 to 4As shown, the testing mechanism 5 includes blowers 51 fixedly connected to both sides of the bottom end inside the base box 2. Each blower 51 has a telescopic pipe 52 fixedly connected to its outlet end, and a sealing plate 53 is fixedly connected to the top end of each telescopic pipe 52. A sealing gasket 11 is fixedly connected to the rear side of each sealing plate 53. The diameter of the sealing gasket 11 is larger than the diameter of the glove opening 4, which helps to enhance the sealing performance of the sealing plate 53 to the glove opening 4. Each sealing plate 53 has an air inlet 54 on its surface. A set of slots 55 is provided at both ends of the front side of the glove box body 1. Each set of slots 55 is circumferentially located on the outside of the glove opening 4. A set of inserts 56 is circumferentially fixedly connected to the side of the glove opening 4 closest to the slot 55. A fixing plate 9 is fixedly connected inside the base box 2. The top end of the telescopic pipe 52 extends to the top of the fixing plate 9. The design of the fixing plate 9 allows the sealing plate 53 to be placed on the fixing plate 9 after the telescopic pipe 52 retracts. The diameter of cylinder 61 is the same as the diameter of rotating column 62, and the diameter of rotating column 62 is the same as the diameter of circular opening 66, which enables positioning. After rotating column 62 enters circular opening 66, circular opening 66 corresponds exactly to slot 55. A guide roller 10 is provided inside the base box 2, and both ends of the guide roller 10 are rotatably connected to the two sides inside the base box 2. The guide roller 10 guides the elongated telescopic tube 52, preventing friction between the elongated telescopic tube 52 and the top of the base box 2, thus reducing friction.

[0028] During operation, extend the telescopic tube 52 to pull the sealing disc 53 out of the base box 2. Then, insert the insertion post 56 into the slot 55, ensuring an interference fit between the insertion post 56 and the slot 55. Force is required to insert the insertion post 56 into the slot 55 until the sealing disc 53 is tightly fitted to the glove box body 1. The anti-detachment mechanism 6 further prevents the sealing disc 53 from separating from the glove box body 1. Turn on the power to the blower 51. The blower 51 draws in outside air and inputs it into the telescopic tube 52. The air is then introduced into the glove inside the glove opening 4 through the air inlet 54, fully expanding the glove. Turn off the blower 51, maintaining the open glove position. The condition is observed for a period of time. If the condition of the glove remains unchanged, it means that the glove is intact. If the glove becomes deflated, it means that the glove is damaged and needs to be replaced in time. The structure then inserts the insert 56 into the slot 55 to make the sealing plate 53 fit tightly with the glove box body 1, avoiding the glove opening 4. The blower 51 uses the telescopic tube 52 to supply air to the glove inside the glove opening 4, so that it is opened. Then, by observing whether the glove deflates, it is determined whether the glove is intact. The interference fit between the insert 56 and the slot 55 helps to avoid excessive pressure inside the glove, which would cause the sealing plate 53 to detach from the glove box body 1.

[0029] Please see Figures 2 to 4As shown, the anti-drop mechanism 6 includes cylinders 61 on both sides of the glove opening 4. The rear ends of each cylinder 61 are fixedly connected to the glove box body 1, and the front ends of each cylinder 61 are rotatably connected to a rotating column 62. A spring 63 is fitted onto the outer side of each cylinder 61, and the rear ends of each spring 63 are fixedly connected to the glove box body 1. Abutments 64 are fixedly connected to the rear ends of both sides of the rotating column 62. Connecting ears 65 are fixedly connected to both ends of the sealing disc 53. A circular opening 66 is formed on the surface of each connecting ear 65, and through openings 67 are formed on both sides of the circular opening 66. The diameter of the cylinder 61 is the same as the diameter of the rotating column 62, and the diameter of the rotating column 62 is the same as the diameter of the circular opening 66, enabling positioning. After the rotating column 62 enters the circular opening 66, the circular opening 66 corresponds exactly to the slot 55.

[0030] During operation, the sealing disc 53 moves the connecting ear 65 closer to the glove opening 4, and the rotating column 62 inserts into the round opening 66, then presses the sealing disc 53. The sealing disc 53, in turn, causes the connecting ear 65 to press against the spring 63, compressing the spring 63. When the abutment 64 just passes through the through-hole 67, the sealing disc 53 is tightly fitted against the side of the glove box body 1. Then, the rotating column 62 is rotated, causing the abutment 64 to rotate, thus dislocating the abutment 64 from the through-hole 67. At this point, under the action of the spring 63, the abutment 64 can fix the sealing disc 53, preventing excessive air pressure inside the glove and thus preventing a seal. When the sealing disc 53 is squeezed outward, a gap occurs between it and the glove opening 4. The structure then inserts the rotating column 62 into the circular opening 66 and compresses the spring 63. When the abutment block 64 just passes through the through-hole 67, the sealing disc 53 is tightly fitted against the side of the glove box body 1. Rotating the rotating column 62 causes the abutment block 64 to be displaced from the through-hole 67. At this time, the abutment block 64 fixes the sealing disc 53, preventing the sealing disc 53 from being squeezed outward due to excessive internal air pressure after the glove is inflated. This ensures the sealing performance of the sealing disc 53 to the glove opening 4.

[0031] The above description is only a preferred embodiment of the present invention and is not intended to limit the present invention. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of the present invention should be included within the protection scope of the present invention.
