Detailed Implementation

[0029] 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 a part of the embodiments of the present invention, and not all of them. All other embodiments obtained by those skilled in the art based on the embodiments of the present invention without creative effort are within the scope of protection of the present invention.

[0030] Please see Figures 1 to 7 As shown, this embodiment of the invention provides a glove leakage detection device for a glove box, including a detection platform 1 for placing the entire detection device, a detection structure 2 for detecting leakage in the gloves on the detection platform 1, a clamping structure 3 for clamping the ends of the gloves on the detection platform 1, a transmission structure 4 for detecting the gloves on the detection platform 1, a pushing structure 5 for pushing the transmission structure 4 inside the detection platform 1, a sealing structure 6 for sealing during glove detection inside the detection platform 1, and a rotating structure 7 for driving the sealing mechanism to rotate on one side of the detection platform 1. The specific structures and functions of the detection structure 2, clamping structure 3, transmission structure 4, pushing structure 5, sealing structure 6, and rotating structure 7 will be described in detail below.

[0031] Please see Figures 1 to 4 As shown, the detection structure 2 includes a fixed base 201. Two fixed bases 201 are fixedly connected to the detection platform 1. Sleeves 202 are slidably connected inside each fixed base 201. A fixing block 203 is fixedly connected to the top of each sleeve 202. An air inlet pipe 204 is provided on one side of the detection platform 1. Corresponding to the air inlet pipe 204, an air delivery pipe 205 is provided on the detection platform 1. One end of the air delivery pipe 205 is fixedly connected to the fixed base 201. A cavity 206 is provided inside the fixed base 201. An air outlet groove 207 is provided on the fixed base 201. A sealing ring 209 is fixedly connected to the fixed base 201. A protective plug 208 is fixedly connected to the bottom end of the fixing block 203. The protective plug 208 can engage with the air outlet groove 207, thereby easily sealing the air outlet groove 207 and preventing dust from falling in.

[0032] In a specific embodiment of the present invention, when it is necessary to detect air leakage in the gloves of the glove box, the air is delivered to the cavity 206 in the fixed seat 201 through the air inlet pipe 204 and the air outlet pipe 205, and the gloves are filled with gas through the air outlet groove 207. The gas inside the gloves keeps the gloves in an inflated state, and the state of the gloves is used to detect whether the gloves are leaking. When the gloves are not being tested, the fixed block 203 is driven to slide down through the sleeve 202, which can make the protective plug 208 on the fixed block 203 engage with the air outlet groove 207, sealing the air outlet groove 207 and preventing dust from falling into the air outlet groove 207.

[0033] Please see Figures 1 to 3As shown, the clamping structure 3 includes an air bladder 301. The air bladder 301 is housed within the testing platform 1. Two pressure blocks 302 are slidably connected within the testing platform 1, and the two pressure blocks 302 abut against both ends of the air bladder 301. A connecting pipe 303 is fixedly connected to one side of the air bladder 301. A fixing ring 304 is fixedly connected to the fixing seat 201. One end of the connecting pipe 303 passes through the fixing ring 304 and is fixedly connected to an air bladder ring 305, facilitating the fixing of the glove end via the air bladder ring 305. In this embodiment, during use, the air bladder 301 is compressed, and gas is delivered to the air bladder ring 305 through the connecting pipe 303, causing the air bladder ring 305 to expand and maintain pressure, thereby pressing the glove end tightly, reducing wear, and preventing leakage or detachment of the glove end during subsequent leak-proof testing.

[0034] Please see Figures 1 to 3 As shown, the transmission structure 4 includes a lead screw 401. Two lead screws 401 are rotatably connected inside the testing platform 1. Both lead screws 401 are threadedly connected to the sleeve 202. A first pulley 402 is fixedly connected to each of the two lead screws 401. The two first pulleys 402 are driven by a first belt 403, which facilitates simultaneous testing of two gloves. In this embodiment, the glove to be tested is fitted onto the sleeve 202. The motor is started, driving one of the lead screws 401 inside the testing platform 1 to rotate. The bevel gear 502 on the lead screw 401 meshes with the bevel gear 502 on the rotating shaft 501, driving the rotating shaft 501 to rotate. When the lead screw 401 rotates, it can drive the sleeve 202 inside the fixed seat 201 to move upward, extending the glove and preventing the glove from bending together and being damaged during inflation. Simultaneously, when the motor drives one lead screw 401 to rotate, it can drive another lead screw 401 in the testing table 1 to rotate through the first pulley 402 and the first belt 403, thus testing two gloves at the same time and improving work efficiency. After the gloves are tested, the motor reverses to drive the lead screw 401 to rotate, causing the sleeve 202 to slide down. It also drives the rotating shaft 501 to reverse through the bevel gear 502, causing the threaded block 503 and the pressure block 302 to slide, so that the air bladder ring 305 no longer expands and no longer fixes the end of the glove.

[0035] Please see Figure 5As shown, the pushing structure 5 includes a rotating shaft 501, which is located inside the detection table 1. Both the rotating shaft 501 and the lead screw 401 are fixedly connected to bevel gears 502, which mesh with the bevel gears 502 on the lead screw 401 and the rotating shaft 501. A threaded block 503 is threadedly connected to the rotating shaft 501, and the threaded block 503 is fixedly connected to the pressure block 302. A limit block 504 is fixedly connected to the threaded block 503, and the limit block 504 is slidably connected to the detection table 1. This facilitates fixing the end of the glove when raising and lowering the sleeve 202. In this embodiment of the invention, the bevel gear 502 on the lead screw 401 meshes with the bevel gear 502 on the rotating shaft 501, causing the rotating shaft 501 to rotate. When the lead screw 401 rotates, it can drive the sleeve 202 inside the fixed seat 201 to move upward, extending the glove and preventing the glove from bending together and being damaged during inflation. At the same time, the rotating shaft 501 drives the threaded block 503 to slide within the testing table 1, causing the pressure block 302 fixed to the threaded block 503 to slide. The bevel gear 502 drives the rotating shaft 501 to reverse, causing the threaded block 503 and the pressure block 302 to slide, so that the airbag ring 305 no longer inflates and no longer fixes the end of the glove.

[0036] Please see Figures 6 to 7 As shown, the enclosed structure 6 includes a fixed disk 601, which is rotatably connected to the detection table 1. A sliding disk 602 is slidably connected to the detection table 1, and a spring 603 is fixedly connected between the sliding disk 602 and the detection table 1. A protrusion 604 is fixedly connected to the fixed disk 601, and a groove 605 is provided on the sliding disk 602. The protrusion 604 and the groove 605 engage. A rubber ring 606 is fixedly connected to the fixed disk 601, and the sliding disk 602 engages with the rubber ring 606. This design facilitates the sealing of airflow when not in use, preventing gas backflow.

[0037] Please see Figures 6 to 7 As shown, the rotating structure 7 includes a fixed shaft 701, which is fixedly connected to a fixed disk 601, and slidably connected to a sliding disk 602. A second pulley 702 is fixedly connected to both the fixed shaft 701 and the air pump, and the two second pulleys 702 are driven by a second belt 703. This facilitates the rotation of the fixed shaft 701 by the air pump.

[0038] In this embodiment of the invention, the fixed shaft 701 can be rotated by the second pulley 702 and the second belt 703, which in turn drives the fixed disk 601 on the fixed shaft 701 to rotate. This causes the protrusion 604 on the fixed disk 601 to no longer engage with the groove 605 on the sliding disk 602, thereby causing the sliding disk 602 to compress the spring 603. This facilitates the entry of gas from the inlet pipe 204 into the outlet pipe 205. When the gloves do not need to be tested, the elastic force of the spring 603 can cause the protrusion 604 and the groove 605 to engage, sealing the gap between the inlet pipe 204 and the outlet pipe 205 and preventing gas backflow.

[0039] The specific working process and principle of this invention are as follows: When using this invention, firstly, the glove to be tested is fitted onto the sleeve 202. Then, the motor is started, driving a lead screw 401 inside the testing platform 1 to rotate. The bevel gear 502 on the lead screw 401 meshes with the bevel gear 502 on the rotating shaft 501, causing the rotating shaft 501 to rotate. When the lead screw 401 rotates, it can drive the sleeve 202 inside the fixed base 201 to move upwards, extending the glove and preventing it from bending and being damaged during inflation. Simultaneously, the rotating shaft 501 drives the threaded block 503 to slide within the testing platform 1, causing the pressure block 302, which is fixed to the threaded block 503, to slide, compressing the large air bladder 301. Gas is delivered to the airbag ring 305 through the connecting pipe 303, causing the airbag ring 305 to expand and maintain pressure, thereby pressing the end of the glove tightly, reducing wear, and preventing the end of the glove from easily leaking or detaching during subsequent leak-proof testing. Then, the air pump is started, delivering gas through the air inlet pipe 204 and the air outlet pipe 205 to the cavity 206 in the fixed base 201, and filling the glove with gas through the air outlet groove 207. The gas inside the glove keeps it inflated, and the state of the glove is used to detect whether there is a leak. Simultaneously, when the motor drives a lead screw 401 to rotate, it passes through the first pulley 402 and the first belt 403... The transmission can drive another lead screw 401 inside the testing table 1 to rotate, simultaneously testing two gloves and improving work efficiency. After the gloves are tested, the motor reverses, driving the lead screw 401 to rotate, causing the sleeve 202 to slide down. This, in turn, drives the rotating shaft 501 to reverse through the bevel gear 502, causing the threaded block 503 and the pressure block 302 to slide, preventing the air bladder ring 305 from inflating and thus removing the fixation of the glove end. This allows the glove to be replaced for testing other gloves. When not testing gloves, the sleeve 202 drives the fixing block 203 to slide down, causing the protective plug 208 on the fixing block 203 to engage with the air outlet groove 207, sealing the air outlet groove 207. To prevent dust from falling into the air outlet 207, when the air pump is started, the second pulley 702 and the second belt 703 drive the fixed shaft 701 to rotate, which in turn drives the fixed disk 601 on the fixed shaft 701 to rotate. This causes the protrusion 604 on the fixed disk 601 to no longer engage with the groove 605 on the sliding disk 602, causing the sliding disk 602 to compress the spring 603, facilitating the flow of gas from the air inlet pipe 204 into the air delivery pipe 205. When the gloves do not need to be tested, the spring force of the spring 603 can cause the protrusion 604 and the groove 605 to engage, sealing the gap between the air inlet pipe 204 and the air delivery pipe 205 and preventing gas backflow.
