Description

Technical Field

[0001] The utility model relates to the technical field of glove testing, in particular to a nitrile glove pinhole testing device capable of automatically filling with water. Background Art

[0002] Nitrile gloves are widely used in medical, laboratory, and food processing applications requiring protective equipment. Their primary function is to provide a barrier, preventing direct contact between hands and foreign substances. However, during use, nitrile gloves may develop tiny defects such as pinholes. These defects can reduce the gloves' protective effectiveness or even cause them to lose their intended protective function. Therefore, pinhole testing of nitrile gloves is an important step in ensuring their quality.

[0003] There are various methods for pinhole detection, and the water injection pinhole test is a commonly used and effective method. This method determines whether the glove has pinholes by injecting water into the glove to observe whether water seeps out from tiny defects such as pinholes. However, in actual operation, the water injection pinhole test has some problems. For example, during the water injection process, due to the elasticity of the glove material, the gloves can easily fall off from the fixed position, making the test difficult to carry out smoothly, affecting the accuracy and efficiency of the test. In addition, after the test is completed, the gloves usually need to be removed separately from the testing equipment. This operation is time-consuming and labor-intensive, increasing the workload of the operator. The slippery nature of the gloves also makes the removal process difficult.

[0004] In summary, current methods for pinhole detection in nitrile gloves have certain limitations, particularly the tendency for gloves to fall off during water injection and the need to be collected separately after testing. This places higher demands on detection efficiency and operational convenience. Therefore, an improved device or method for pinhole detection in nitrile gloves is urgently needed to address these issues and improve detection efficiency and accuracy.

[0005] Therefore, we propose a nitrile glove pinhole testing device that can automatically fill with water. Utility Model Content

[0014] Beneficial effects

[0015] The utility model provides a nitrile glove pinhole testing device that can automatically fill with water. It has the following beneficial effects:

[0016] (1) This is a nitrile glove pinhole testing device that can automatically fill water. After the gloves are filled with water, a timer starts and an alarm is sounded. A cylinder pressure plate is used to fix the gloves and uniformly fill the same amount of water. The original device manually opens and closes the valves one by one, which cannot achieve time uniformity. The duration of the first and last gloves is quite different.

During the sliding process, the nitrile glove contacts the soft pressure sleeve, and as the sleeve slides upward, the soft pressure sleeve is driven to enter the inner side of the hard pressure plate. As the thickness of the hard pressure plate gradually increases, the nitrile glove is gradually pressed by the soft pressure sleeve during the process of following the sleeve to slide upward, so that it will not fall off the sleeve.

[0018] (3) This is a nitrile glove pinhole testing device that can automatically fill with water. After the test is completed, the hydraulic telescopic rod drives the movable plate to slide down, and then the sleeve slides down, so that the nitrile glove is separated from the soft pressure sleeve. At this time, the gloves filled with water slide into the collection box. Under the guidance of the guide plate, all gloves slide to the filter plate, and the filter plate filters out the water, which is convenient for collection and wastewater utilization.

[0027] The following will be combined with the drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the embodiments described are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without making creative efforts are within the scope of protection of the present invention.

[0028] A nitrile glove pinhole testing device that can automatically fill with water, such as Figures 1-4 As shown, it includes two groups of brackets 1, and a movable plate 4 and a fixed plate 7 are respectively provided between the two groups of brackets 1 from top to bottom. The movable plate 4 and the fixed plate 7 are both rectangular plates. A sleeve 5 is fixedly installed on the movable plate 4 at a position corresponding to the bottom of the water bucket 3. The sleeve 5 is a circular tube. The sleeve 5 passes through the fixed plate 7 and extends to the bottom of the fixed plate 7. A fixed collar frame 8 is fixedly installed at the position of the fixed plate 7 corresponding to the sleeve 5. The fixed collar frame 8 is a circular tube and the bottom surface of the fixed collar frame 8 radially protrudes. The bottom end surface of the fixed collar frame 8 is also integrally formed with a hard pressing plate 9. The hard pressing plate 9 is a circular tube. The inner diameter of the hard pressing plate 9 is 1.1 times the inner diameter of the fixed collar frame 8, and the outer diameter of the hard pressing plate 9 is 0.9 times the outer diameter of the fixed collar frame 8. Therefore, the hard pressing plate The plate 9 divides the bottom end surface of the fixed ring frame 8 into two parts, an inner and an outer part, wherein the outer part forms an installation platform 10, and a soft pressure sleeve 11 is fixedly installed on the installation platform 10. The soft pressure sleeve 11 is a flexible part, and in this embodiment, it is made of rubber. The other end of the soft pressure sleeve 11 is fixedly installed on the inner ring of the hard pressure plate 9, wherein the thickness of the hard pressure plate 9 gradually decreases from the outer ring to the inner ring. When the nitrile glove is sleeved on the bottom end surface of the sleeve 5, the sleeve 5 is slid upward. During the sliding process, the nitrile glove contacts the soft pressure sleeve 11. As the sleeve 5 slides upward, the soft pressure sleeve 11 is driven into the inner side of the hard pressure plate 9. Because the thickness of the hard pressure plate 9 gradually increases, the nitrile glove is gradually pressed by the soft pressure sleeve 11 during the sliding process of the sleeve 5, so that it will not fall off the sleeve 5.

[0029] In order to improve the stability of the nitrile glove being sleeved on the sleeve 5, a clamping ring 6 is provided on the bottom outer wall of the sleeve 5. The clamping ring 6 is an annular ring and increases the resistance of the glove.

[0030] Furthermore, a top plate 2 is fixedly installed on the top of the bracket 1, and water buckets 3 are fixedly installed on the top plate 2 at even intervals. Test water is stored in the water buckets 3, and a water injection pipe 14 is integrally formed on the lower end face of the water bucket 3. The water injection pipe 14 is located above the sleeve 5 and is coaxial with the sleeve 5. When the sleeve 5 slides up following the movable plate 4, the water injection pipe 14 is inserted into the sleeve 5, so that water flows completely into the sleeve 5. Furthermore, a pneumatic valve 13 is fixedly installed on the water injection pipe 14, and the pneumatic valve 13 controls the opening and closing of the water injection pipe 14.

[0031] Furthermore, a hydraulic telescopic rod 12 is fixedly mounted on the bracket 1 , and an output end of the hydraulic telescopic rod 12 is fixedly connected to the movable plate 4 . When the hydraulic telescopic rod 12 is activated, the movable plate 4 can be controlled to slide up and down.

[0032] Furthermore, a controller 15 is fixedly mounted on the bracket 1. The controller 15 is electrically connected to the pneumatic valve 13 and the hydraulic telescopic rod 12, respectively, and can control the opening and closing of the pneumatic valve 13 and the hydraulic telescopic rod 12. A timing alarm device is also provided in the controller 15. When the pneumatic valve 13 and the hydraulic telescopic rod 12 are opened, water is injected into the glove. After a certain period of time, an alarm is sounded to remind the inspector to observe whether the glove is leaking due to the presence of pinholes.

[0033] Furthermore, the outer diameter of the sleeve 5 is the same as the inner diameter of the fixed collar frame 8, so no shaking occurs when the sleeve 5 slides up and down, thereby increasing the stability of the equipment.

[0034] Furthermore, a collecting box 16 is fixedly installed on the lower end face of the bracket 1, and the top of the collecting box 16 is open. A guide plate 17 is fixedly installed in the middle of the collecting box 16. The guide plate 17 is a rectangular plate with an inclined top face. A filter plate 18 is fixedly installed on the lower part of the guide plate 17. The filter plate 18 is a metal mesh. When the inspection is completed, the hydraulic telescopic rod 12 drives the movable plate 4 to slide down, and then the sleeve 5 slides down, so that the nitrile gloves are separated from the soft pressure sleeve 11. At this time, the gloves filled with water slide into the collecting box 16. Under the guidance of the guide plate 17, all the gloves slide to the filter plate 18. The filter plate 18 filters out the water, which is convenient for collection and wastewater utilization.

[0035] The working principle of the present invention is as follows: after the gloves are sleeved on the sleeve 5, the controller 15 controls the hydraulic telescopic rod 12 and the pneumatic valve 13 to be opened in sequence, and the hydraulic telescopic rod 12 controls the sleeve 5 to slide upward through the movable plate 4. During the sliding process, the nitrile gloves come into contact with the soft pressure sleeve 11. As the sleeve 5 slides upward, the soft pressure sleeve 11 is driven to be inserted into the inner side of the hard pressure plate 9. As the thickness of the hard pressure plate 9 gradually increases, the nitrile gloves are gradually pressed by the soft pressure sleeve 11 as they follow the sleeve 5 to slide upward, so that they will not fall off the sleeve 5.

[0036] By using the timing alarm device in the controller 15, when the pneumatic valve 13 and the hydraulic telescopic rod 12 are opened, water is injected into the glove, and an alarm is sounded after a certain period of time, reminding the inspector to observe whether the glove is leaking due to pinholes.

[0037] After the inspection is completed, the hydraulic telescopic rod 12 drives the movable plate 4 to slide down, and then the sleeve 5 slides down, so that the nitrile gloves are separated from the soft pressure sleeve 11. At this time, the gloves filled with water slide into the collection box 16. Guided by the guide plate 17, all gloves slide to the filter plate 18. The filter plate 18 filters out the water, which is convenient for collection and wastewater utilization.

[0038] The above shows and describes the basic principles, main features and advantages of the present invention. Those skilled in the art should understand that the present invention is not limited to the above embodiments. The above embodiments and descriptions are merely illustrative of the principles of the present invention. Various changes and improvements may be made to the present invention without departing from the spirit and scope of the present invention. Such changes and improvements are intended to fall within the scope of the present invention. The scope of protection claimed in this invention is defined by the appended claims and their equivalents.
