Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0021] Please see Figure 1-4 This utility model provides a technical solution: a chemical-resistant nitrile glove testing device, comprising a base 1, a servo motor 2, an adjusting rod 3, an adjusting sleeve 4, a bracket 5, an electric telescopic rod 6, a drive motor 7, a square rod sleeve 8, an inner square rod 9, a positioning ring 10, a spherical grinding head 11, a positioning plate 12, a support plate 13, a cylinder 14, a suspension rod 15, a tension gauge 16, a clamping mechanism 17, a clamping seat 1701, a knob 1702, and a clamping plate 1703. The servo motor 2 is installed on the inner wall of the end of the base 1, and the adjusting rod 3 is fixedly connected to the end of the output shaft of the servo motor 2. The adjusting sleeve 4 is sleeved on the outer wall of the adjusting rod 3, and the bracket 5 is fixedly connected to the upper surface of the adjusting sleeve 4. The upper surface of the bracket 5 is also equipped with... The device includes an electric telescopic rod 6 and a drive motor 7. A square rod sleeve 8 is fixedly connected to the upper end of the output shaft of the drive motor 7. An inner square rod 9 is movably arranged on the inner wall of the square rod sleeve 8. A positioning ring 10 is fixedly installed on the upper outer wall of the inner square rod 9. A spherical grinding head 11 is fixedly arranged on the upper end face of the inner square rod 9. A positioning plate 12 is movably connected to the outer wall of the positioning ring 10. A support plate 13 is fixedly connected to the end of the upper surface of the base 1. A cylinder 14 is installed on the upper outer wall of the side of the support plate 13. A suspension rod 15 is fixedly connected to the lower surface of the output shaft of the cylinder 14. A tension gauge 16 is arranged at the lower end of the suspension rod 15. A clamping mechanism 17 is installed at the end of the output shaft of the tension gauge 16 and on the surface of the support plate 13.

[0022] The adjusting rod 3 and the base 1 are rotatably connected, and the adjusting rod 3 and the adjusting sleeve 4 are threaded together. The base 1 and the bracket 5 form a sliding structure, which makes it easy for the servo motor 2 to drive the adjusting rod 3 to rotate relative to the base 1, so that the adjusting sleeve 4 drives the bracket 5 to move relative to the base 1, thereby adjusting the position of the ball grinding head 11, which makes it easy for the ball grinding head 11 to detect different positions of the glove.

[0023] The square rod sleeve 8 and the inner square rod 9 are slidably configured so that when the electric telescopic rod 6 pushes the positioning plate 12 to adjust the height of the spherical grinding head 11, the inner square rod 9 slides relative to the square rod sleeve 8.

[0024] The positioning plate 12 and the positioning ring 10 form a rotating structure, and the positioning plate 12 and the output shaft of the electric telescopic rod 6 are fixedly connected. This facilitates the driving motor 7 to drive the square rod sleeve 8 so that when the inner square rod 9 rotates, the inner square rod 9 drives the positioning ring 10 to rotate relative to the positioning plate 12, thereby making the inner square rod 9 rotate stably and facilitating the electric telescopic rod 6 to push the positioning plate 12 to move.

[0025] The clamping mechanism 17 includes a clamping base 1701, a knob 1702, and a clamping plate 1703. The clamping base 1701 is fixed to the end of the output shaft of the tension gauge 16 and the surface of the support plate 13, respectively. The knob 1702 is movably connected to the upper inner wall of the clamping base 1701, and the clamping plate 1703 is rotatably mounted on the lower end of the knob 1702, so as to facilitate the clamping mechanism 17 to limit the glove.

[0026] The clamp 1703 and the clamp base 1701 are slidably configured, and the clamp base 1701 and the knob 1702 are threadedly connected, which makes it easy for the user to rotate the knob 1702 so that the knob 1702 moves down relative to the clamp base 1701, so that the clamp 1703 and the clamp base 1701 fit against the glove to fix the glove.

[0027] Working principle: When using this chemical-resistant nitrile glove testing equipment, firstly as follows... Figure 1-4As shown, the user inserts one end of the chemical-resistant nitrile glove between the clamp 1701 and clamp 1703 on the support plate 13. Then, the user rotates the knob 1702, causing it to move downwards relative to the clamp 1701. This pushes the clamp 1703 downwards relative to the clamp 1701, bringing the clamp 1703 into close contact with the glove, thus securing one end of the glove. Similarly, the other end of the glove is secured to the clamping mechanism 17 on the tension gauge 16. The user then activates the cylinder 14, which pushes the suspension rod 15, causing the tension gauge 16 to move and the clamping mechanism 17, thus stretching the glove for a tensile test. Simultaneously, the user monitors the tensile force on the glove in real time based on the data displayed on the tension gauge 16. When testing the glove's abrasion resistance, as shown above, the user secures the glove to the device and then activates the servo motor 2. The servo motor 2 then rotates the adjusting rod 3 relative to the base 1, and subsequently adjusts the sleeve 4... The adjusting rod 3 is moved, and then the adjusting sleeve 4 drives the bracket 5 to slide relative to the base 1. Next, the bracket 5 drives the ball grinding head 11 to move and adjust the position of the ball grinding head 11 relative to the glove. After the position of the ball grinding head 11 is adjusted, the user starts the electric telescopic rod 6. Then, the electric telescopic rod 6 drives the positioning plate 12 to move upward. Next, the positioning plate 12 drives the positioning ring 10 to move upward. Then, the positioning ring 10 drives the inner square rod 9 to move upward relative to the square rod sleeve 8, so that the ball grinding head 11 moves upward and fits against the glove. Then, the user starts the drive motor 7. Next, the drive motor 7 drives the square rod sleeve 8 to rotate. Then, the square rod sleeve 8 drives the inner square rod 9 to rotate. At this time, the inner square rod 9 drives the positioning ring 10 to rotate relative to the positioning plate 12, so that the inner square rod 9 drives the ball grinding head 11 to rotate stably for glove abrasion resistance testing. Therefore, the device is convenient for abrasion resistance testing of gloves, which makes it convenient for staff to optimize the performance of gloves based on their abrasion resistance, thus improving the practicality of the device.

[0028] Although the present invention has been described in detail with reference to the foregoing embodiments, those skilled in the art can still modify the technical solutions described in the foregoing embodiments or make equivalent substitutions for some of the technical features. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of the present invention should be included within the protection scope of the present invention.
