Abstract
Description
Technical Field
[0001] The utility model belongs to the technical field of air purification, in particular to a rubber glove leak detection device for an inspection box. Background Art
[0002] The glove inspection box is filled with high-purity inert gas and has a circulating filtration function to remove moisture, oxygen and other active substances in the air, creating a water-free and oxygen-free inspection environment. In order to ensure the sealing of the rubber gloves used in the inspection box, they need to be leak tested. When the rubber gloves leave the factory, they are leak tested one by one by large equipment. During transportation or installation, the rubber gloves may still be damaged. Therefore, when the rubber gloves are installed on the inspection box, they need to be leak tested again. However, the users of the glove inspection box do not have low-cost small rubber glove leak detection devices. There may be leakage problems after installing and replacing the rubber gloves, which affects the normal use of the glove inspection box. Summary of the invention
[0003] The technical problem to be solved by the utility model is to provide a low-cost small-sized rubber glove leak detection device for an inspection box.
[0004] In order to solve the above technical problems, the present invention is realized by the following technical scheme: a rubber glove leak detection device for an inspection box, comprising a main pipeline, a bearing plate, a first branch pipeline, a second branch pipeline, a sleeve, a dial gauge, an end cover, a piston, an adjustable weight, a stop ring and a guide rod, wherein the main pipeline has an air inlet and a test port, the test port is fixedly covered with a first sealing rubber sleeve on the outside, the sleeve is slidably sleeved and installed on the main pipeline, and a second sealing rubber sleeve is fixedly attached and installed on the inner wall of the sleeve, the bearing plate is fixedly sleeved and installed on the main pipeline, the lower end of the guide rod is fixedly installed on the bearing plate, and the upper end of the guide rod is slidably installed in the sleeve, the two ends of the first branch pipeline are respectively sealed and fixedly connected with the main pipeline and the second branch pipeline, the piston is slidably sealed and installed in the second branch pipeline, the lower part of the piston is screwed with an adjustable weight, the stop ring is fixedly installed on the inner wall of the second branch pipeline, the piston is placed on the stop ring, the main body of the dial gauge is fixedly installed on the end cover, the end cover is screwed on the top of the second branch pipeline, and the contact of the dial gauge is pressed on the upper part of the piston.
[0005] Preferably, a non-slip rubber sleeve is fixedly mounted on the sleeve.
[0006] Preferably, the anti-skid rubber sleeve has mesh anti-skid patterns.
[0007] Preferably, the lower end of the guide rod is screwed and fixed on the bearing plate.
[0008] Compared with the prior art, the advantages of the utility model are: the overall size of the leak detection device is small and the manufacturing cost is low. It can work by connecting the air inlet of the main pipeline to the constant pressure air tank. The sealing and fixing of the rubber gloves to be tested and the main pipeline are simple. The rubber gloves can be pressed and fixed by pushing the sleeve upwards through the cooperation of the second sealing rubber sleeve and the first sealing rubber sleeve. By observing the value of the micrometer, it can be intuitively judged whether the rubber gloves have leakage problems, which can meet the daily use needs of glove inspection box users for leak detection tests when installing and replacing rubber gloves. BRIEF DESCRIPTION OF THE DRAWINGS
[0009] The utility model is further described below in conjunction with the accompanying drawings.

[0012] The utility model is described in detail below in conjunction with specific implementation methods:
[0013] like Figure 1 and Figure 2 The rubber glove leak detection device for an inspection box shown in the figure comprises a main pipeline 1, a bearing plate 2, a first branch pipeline 3, a second branch pipeline 31, a sleeve 4, a micrometer 6, an end cover 7, a piston 8, an adjustable weight 81, a stop ring 9 and a guide rod 10. The main pipeline 1 has an air inlet 11 and a test port 12. The test port 12 is fixedly covered with a first sealing rubber sleeve 13 on the outside. The sleeve 4 is slidably sleeved on the main pipeline 1. A second sealing rubber sleeve 41 is fixedly attached to the inner wall of the sleeve 4. The bearing plate 2 is fixedly sleeved on the main pipeline 1. The guide rod 1 0 is fixedly mounted on the bearing plate 2, the upper end of the guide rod 10 is slidably mounted in the sleeve 4, the two ends of the first branch pipe 3 are respectively sealed and fixedly connected with the main pipe 1 and the second branch pipe 31, the piston 8 is slidably and sealedly mounted in the second branch pipe 31, the lower part of the piston 8 is screwed with an adjustable weight 81, the stop ring 9 is fixedly mounted on the inner wall of the second branch pipe 31, the piston 8 is placed on the stop ring 9, the main body of the micrometer 6 is fixedly mounted on the end cover 7, the end cover 7 is screwed on the top of the second branch pipe 31, and the contact of the micrometer 6 is pressed on the upper part of the piston 8.
[0014] In actual use, in order to increase the operating comfort of the tester holding the sleeve 4 and increase the anti-skid property, an anti-skid rubber sleeve 5 is fixedly mounted on the sleeve 4, and the anti-skid rubber sleeve 5 has a mesh anti-skid pattern.
[0015] After the guide rod 10 is worn or bent, in order to facilitate its disassembly and replacement, the lower end of the guide rod 10 is screwed and fixedly installed on the bearing plate 2.
[0016] The rubber glove to be tested is sleeved and installed on the first sealing rubber sleeve 13 on the top of the main pipeline 1, and the sleeve 4 is pushed to move upward so that the second sealing rubber sleeve 41 is sleeved and installed on the first sealing rubber sleeve 13. At this time, the second sealing rubber sleeve 41 presses and seals the lower opening of the rubber glove and fixes it on the first sealing rubber sleeve 13. The constant pressure air tank is started to supply air to the air inlet 11. After the rubber glove to be tested is blown and expanded, if the rubber glove to be tested is not damaged or leaking, the air pressure in the second branch pipeline 31 increases and pushes the piston 8 to overcome its own gravity and the gravity of the adjustable weight 81 to move upward. At this time, the contact of the micrometer 6 moves upward, and the value of the micrometer changes. If the rubber glove to be tested is damaged or leaking, the air pressure in the second branch pipeline 31 cannot reach the driving force to push the piston 8 and the adjustable weight 81 upward, and the pointer of the micrometer will not change.
