Description

Technical Field

[0001] This utility model relates to the field of latex glove production technology, and in particular to an airtightness testing device for latex gloves. Background Technology

[0002] Latex gloves are a type of glove made from natural latex and other fine additives. They can be used in homes, industries, medical settings, and beauty industries, and are essential hand protection products. During the production of latex gloves, their airtightness needs to be tested. If the latex gloves fail the test, they need to be remade, so airtightness testing equipment is required.

[0003] The patent with publication number CN217716805U discloses a device for testing the air tightness of latex gloves, including a support mechanism and a testing mechanism. The testing mechanism includes a pneumatic component, a lifting and fixing component, and a water collection tank. The pneumatic component is installed above the water collection tank and includes an air pump and an air blowing pipe. The air blowing pipe is installed on one side of the air pump. The air blowing pipe includes a connecting pipe, and a bend is provided below the connecting pipe. An air outlet is provided at the lower end of the bend.

[0004] In the above case, the glove was fixed by a clamping component and air was blown into the glove through an air tube to test the air tightness. However, the device could not tightly fix the open end of the glove to the air tube, which caused the glove to be easily blown away from the air tube when air was blown into the glove, making the device unable to work properly and reducing its practicality.

[0005] Therefore, this invention provides an airtightness testing device for latex gloves to meet the requirements. Utility Model Content

[0006] The purpose of this invention is to provide an airtightness testing device for latex gloves, so as to solve the problems mentioned in the background art.

[0007] To achieve the above objectives, this utility model provides the following technical solution: an airtightness testing device for latex gloves, comprising a base plate, a fixing frame fixedly connected to the top of the base plate, a cylinder fixedly connected to the top of the fixing frame, an mounting plate fixedly connected to the bottom of the cylinder, a connecting pipe fixedly connected to the bottom of the mounting plate, a fixing pipe for fixing the latex gloves fixedly connected to the bottom end of the connecting pipe, a protruding ring fixedly connected to the outside of the fixing pipe, and a fixing component slidably connected to the outside of the connecting pipe.

[0008] In a preferred embodiment, the fixing component includes a sliding sleeve slidably connected to the outside of the connecting pipe, with brackets fixedly connected to both sides of the bottom end of the sliding sleeve, and bidirectional screws rotatably connected to both ends of the two brackets.

[0009] In a preferred embodiment, both ends of the two bidirectional screws are threadedly connected to clamps, and the two clamps face opposite directions.

[0010] In a preferred embodiment, one of the clamps is fixedly connected with a locking block around the perimeter of one end near the fixed tube, and the other clamp is provided with a locking groove adapted to the locking block around the perimeter of one end near the fixed tube.

[0011] In a preferred embodiment, an elastic sleeve is fixedly connected to the inner side of the clamp near the fixed tube, and an air filling pipe is fixedly connected to the side of the clamp away from the fixed tube.

[0012] In a preferred embodiment, the end of the gas filling pipe away from the clamp is fixedly connected to a flexible tube, the bottom of the mounting plate is fixedly connected to a gas supply seat, and the top end of the flexible tube is fixedly connected to the gas supply seat.

[0013] In a preferred embodiment, the inner sides of the two clamps are in close contact with the outer side of the fixing tube, the convex ring is located inside the clamps, an air pump is fixedly connected to the bottom of the mounting plate, and its output end is fixedly connected to the connecting pipe. A water storage basin is fixedly connected to the top of the base plate below the fixing tube.

[0014] Compared with the prior art, the beneficial effects of this utility model are:

[0015] This invention, by setting a fixing component, allows the device to adjust the height of the clamps via a sliding sleeve and a bracket, facilitating the placement of the glove's open end onto the fixing tube. The two clamps are simultaneously driven by a bidirectional screw to hold and fix the open end of the latex glove onto the fixing tube, effectively preventing the glove from falling off during inflation and improving the accuracy and reliability of the test.

[0016] This utility model, by setting a convex ring, an elastic sleeve and an air supply pipe, allows the device to input air into the clamp through the air supply pipe and push the elastic sleeve to fit tightly against the fixed tube. Combined with the outward convex design of the convex ring, it further enhances the sealing between the glove and the fixed tube, ensuring that gas will not leak from the connection between the glove and the fixed tube.

[0022] The present invention will be further described below with reference to the embodiments.

[0023] The following embodiments are used to illustrate the present invention, but should not be used to limit the scope of protection of the present invention; the conditions in the embodiments can be further adjusted according to specific conditions, and simple improvements to the method of the present invention under the concept of the present invention are all within the scope of protection claimed by the present invention.

[0024] Please see Figures 1-4 This utility model provides an airtightness testing device for latex gloves, including a base plate 1, a fixing frame 2 fixedly connected to the top of the base plate 1, a cylinder 3 fixedly connected to the top of the fixing frame 2, a mounting plate 4 fixedly connected to the bottom of the cylinder 3, a connecting pipe 5 fixedly connected to the bottom of the mounting plate 4, a fixing pipe 6 for fixing the latex gloves fixedly connected to the bottom end of the connecting pipe 5, a protruding ring 13 fixedly connected to the outside of the fixing pipe 6, a fixing assembly slidably connected to the outside of the connecting pipe 5, the fixing assembly including a sliding sleeve 7 slidably connected to the outside of the connecting pipe 5, brackets 8 fixedly connected to both sides of the bottom end of the sliding sleeve 7, a bidirectional screw 9 rotatably connected to both ends between the two brackets 8, and a clamp 10 threadedly connected to both ends between the two bidirectional screws 9, with the two clamps 10 facing opposite directions.

[0025] Slide the fixing component upwards by sliding the sliding sleeve 7 to avoid obstructing the placement of the latex glove. Place the open end of the latex glove onto the fixing tube 6, ensuring that the open end of the glove completely covers the outside of the convex ring 13. Rotate the two bidirectional screws 9 to make the inner sides of the two clamps 10 move synchronously, clamping the open end of the glove on the outside of the fixing tube 6.

[0026] Rotating the bidirectional screw 9 allows the two clamps 10 to move towards the fixed tube 6 synchronously. Since the threads at both ends of the bidirectional screw 9 are in opposite directions, the two clamps 10 will move towards the fixed tube 6 at the same speed, thus achieving uniform clamping of the open end of the latex glove. This synchronous drive design not only improves the stability of clamping but also avoids deformation or damage to the glove due to uneven clamping force. When the two clamps 10 move close together, the locking block 11 will embed into the locking groove 12, further enhancing the fixing effect between the clamps 10 and the fixed tube 6, ensuring that the latex glove will not fall off during inflation, thereby improving the accuracy and reliability of the test.

[0027] Please see Figures 1-4 One of the clamps 10 has a locking block 11 fixedly connected around its perimeter near the end of the fixed pipe 6. The other clamp 10 has a locking groove 12 adapted to the locking block 11 around its perimeter near the end of the fixed pipe 6. An elastic sleeve 14 is fixedly connected to the inner side of the clamp 10 near the end of the fixed pipe 6. An air supply pipe 15 is fixedly connected to the side of the clamp 10 away from the fixed pipe 6. A hose is fixedly connected to the end of the air supply pipe 15 away from the clamp 10. An air supply seat is fixedly connected to the bottom of the mounting plate 4. The top of the hose is fixedly connected to the air supply seat. The inner sides of the two clamps 10 are in close contact with the outer side of the fixed pipe 6. A convex ring 13 is located inside the clamp 10. An air pump is fixedly connected to the bottom of the mounting plate 4. Its output end is fixedly connected to the connecting pipe 5. A water storage basin 16 is fixedly connected to the top of the base plate 1 below the fixed pipe 6.

[0028] Air is introduced into the air supply pipe 15 through the air supply seat and hose. The air enters the clamp 10, pushes the elastic sleeve 14 to fit tightly against the fixed pipe 6, starts the cylinder 3, drives the mounting plate 4 to move downward, so that the latex glove is immersed in the water in the water storage basin 16. The air pump is started, and air is injected into the latex glove through the connecting pipe 5 and the fixed pipe 6. Observe whether bubbles are formed on the surface of the glove, and then test the air tightness.

[0029] After air is introduced through the air supply pipe 15, the elastic sleeve 14 can fit tightly against the surface of the fixed tube 6. The pressure of the clamp 10 and the air pressure further enhance the sealing performance. The convex structure of the convex ring 13 can fit tightly with the elastic sleeve 14 to form a sealed contact surface. This design not only enhances the sealing performance, but also ensures that gas will not leak from the gap between the clamp 10 and the fixed tube 6 during the inflation process, thus achieving multiple seals at the connection between the open end of the latex glove and the fixed tube 6.

[0030] The working principle and usage process of this utility model are as follows: The fixed component is slid upward by the sliding sleeve 7 to avoid obstructing the placement of the latex glove. The open end of the latex glove is placed on the fixed tube 6, ensuring that the open end of the glove completely covers the outside of the convex ring 13. The two bidirectional screws 9 are rotated so that the inner sides of the two clamps 10 are moved synchronously, clamping the open end of the glove on the outside of the fixed tube 6. Air is introduced into the air supply pipe 15 through the air supply seat and hose. The air enters the clamp 10 and pushes the elastic sleeve 14 to fit tightly against the fixed tube 6. The cylinder 3 is started, driving the mounting plate 4 to move downward, so that the latex glove is immersed in the water in the water storage basin 16. The air pump is started, and air is injected into the latex glove through the connecting pipe 5 and the fixed tube 6. The surface of the glove is observed to see if air bubbles are formed, thereby testing the airtightness.

[0031] Although embodiments of the present invention have been shown and described, it will be understood by those skilled in the art that various changes, modifications, substitutions and alterations can be made to these embodiments without departing from the principles of the present invention, the scope of which is defined by the appended claims and their equivalents.
