[0020] The present invention will be described in further detail below with reference to the accompanying drawings and specific embodiments. The embodiments of the present invention are provided for purposes of illustration and description and are not intended to be exhaustive or to limit the present invention to the disclosed forms. Many modifications and variations will be apparent to those skilled in the art. The embodiments are selected and described to better illustrate the principles and practical applications of the present invention and to enable those skilled in the art to understand the present invention and design various embodiments with various modifications suitable for specific applications.

[0021] like Figure 1-4 The PVC glove airtightness tester shown includes a base 1, a glove seat 2 mounted on the base 1, and a fixed outer cover 3 fitted over the glove seat 2. An air tube 4 is inserted inside the base 1 and the glove seat 2, with the top end of the air tube 4 extending to the top of the glove seat 2.

[0022] The glove base 2 includes a cylindrical stud 5 and a frustum-shaped connecting seat 6. The stud 5 is fixed to the surface of the base 1, and the connecting seat 6 is fixed to the top of the stud 5. The fixing cover 3 includes a screw ring 7 and a limiting cover 8. The screw ring 7 is installed outside the stud 5 by threads, and the limiting cover 8 is frustum-shaped and sleeved outside the connecting seat 6.

[0023] Based on the above, when conducting an airtightness test, the opening of the glove is placed on the glove base 2, and then the fixed outer cover 3 is placed on the outside of the glove base 2 to fix and limit one end of the glove opening between the glove base 2 and the fixed outer cover 3. Then, air is injected into the glove through the air tube 4 using an airtightness testing device. The airtightness of the glove is tested based on the change in air pressure inside the glove after inflation.

[0024] An opening 12 for the glove to pass through is provided on the top of the limiting cover 8, and the top end of the air tube 4 is located inside the opening 12.

[0025] Based on the above, the glove is first put on the outside of the glove seat 2, and then the glove is passed through the opening 12 on the limiting cover 8. The limiting cover 8 is moved towards the opening of the glove until the limiting cover 8 is put on the outside of the glove seat 2. Except for the opening which is put on the connecting seat 6, the other parts of the glove protrude to the outside from the opening 12.

[0026] Based on the above, since the connecting seat 6 is truncated cone-shaped with its diameter decreasing from top to bottom, when the glove is put on the outside, it can be placed in the appropriate position according to the diameter of the glove opening, which can be used for airtightness testing of gloves of different sizes.

[0027] Several inner rubber rings 9 are attached to the outer wall of the connecting seat 6 at equal intervals, and several outer rubber rings 10 are attached to the inner wall of the limiting cover 8 at equal intervals. The size of the inner rubber rings 9 and the outer rubber rings decreases from bottom to top.

[0028] When the limiting cover 8 is fitted outside the connecting seat 6, a number of inner rubber rings 9 and outer rubber rings 10 are arranged alternately. When the limiting cover 8 is fitted outside the connecting seat 6, the inner rubber rings 9 are attached to the outer wall of the connecting seat 6, and the outer rubber rings 10 are attached to the inner wall of the limiting cover 8.

[0029] Based on the above, after the glove opening is placed outside the connecting seat 6, the glove will fit against the inner rubber ring 9 and the outer wall of the connecting seat 6. Then, the fixing cover 3 is installed on the glove seat 2, so that the screw ring 7 is fixedly installed on the stud 5 by the thread. The limiting cover 8 is located outside the glove opening, so that the outer rubber ring 10 on the inner wall of the limiting cover 8 is pressed against the outer wall of the glove opening. Since the inner rubber ring 9 and the outer rubber ring 10 are arranged alternately, when the two simultaneously fit and limit the glove part between the glove seat 2 and the fixing cover 3, the glove part forms a bent S-shape, which can fit tightly between the connecting seat 6 and the limiting cover 8. This makes it difficult for the glove to fall off or leak air during the airtightness test, thus ensuring the accuracy of the airtightness test.

[0030] A pressure sensor 11 is installed on the top of the connector 6. After the glove is fixed and rotated, gas is injected into the glove through the air tube 4 to make it inflate. The pressure sensor 11 is used to obtain the pressure change information inside the glove to complete the airtightness test of the glove.

[0031] A plurality of screw tubes 13 are installed on the limiting cover 8 located at the edge of the opening 12. A lifting screw 14 is inserted into the screw tube 13. The bottom end of the screw 14 extends to the space between the top of the connecting seat 6 and the inner wall of the limiting cover 8. A rubber pad 15 is installed at the bottom end of the screw 14, and a prism-shaped knob 16 is installed at the top end of the screw 14.

[0032] After the glove is installed between the limiting cover 8 and the connecting seat 6, the screw 14 is rotated by the knob 16 to move it into the limiting cover 8. This allows the rubber pad 15 at the end of the screw 14 to press the glove tightly against the top of the connecting seat 6, further improving the clamping force of the glove during the airtightness test and reducing the occurrence of it falling off, shaking, and leaking.

[0033] Obviously, the embodiments described are only some of the embodiments of the present invention, not all of them. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field and related fields without making any creative efforts should fall within the scope of protection of the present invention. Structures, devices, and operating methods not specifically described and explained in this utility model shall be implemented in accordance with conventional means in the field unless otherwise specified or limited.
