Airtightness testing can ensure that the glassware will not leak during use and avoid safety hazards caused by leakage of media. At present, when conducting initial inspection of glassware, cracks are usually detected by manual visual inspection. However, some small cracks cannot be observed by the naked eye, which has certain limitations. Therefore, a glassware testing device is proposed. Utility Model Content

[0006] Preferably, the top of the cylinder has a through groove, and the pull rod passes through the through groove and is clearance-fitted with it.

[0007] Preferably, a spring is sleeved on the outer surface of the pull rod, the upper end of the spring is fixedly connected to the inner surface of the cylinder, and the lower end of the spring is fixedly connected to the piston plate.

[0008] Preferably, the lower surface of the cover has multiple sets of annular slots of different sizes.

[0009] Preferably, a baffle is fixedly connected to the lower end of the connecting rod, the airbag is configured as an annular shape and sleeved on the bottom of the connecting rod, and the bottom of the airbag is fixedly connected to the baffle.

[0010] In summary, this application includes the following beneficial technical effects:

[0011] This invention uses a combination of a cylinder and a cover to detect cracks on the surface of glassware by observing the expansion of the air bladder. The detection method is intuitive, easy to operate, and widely applicable. Attached Figure Description

[0016] The following is in conjunction with the appendix Figure 1-3 This application will be described in further detail.

[0017] This application discloses a glassware testing device, including a cylindrical body 1, a cover 2 fixedly connected to the lower surface of the cylindrical body 1, a sealing gasket fixedly adhered to the inner surface of the cover 2, a connecting rod 10 fixedly connected to the center of the cover 2, an unsaturated air bladder 4 provided at the lower end of the connecting rod 10, and uniformly distributed through holes 7 opened at the connection between the cover 2 and the cylindrical body 1. A piston plate 8 is slidably and sealingly connected inside the cylindrical body 1, and a pull rod 3 is fixedly connected to the upper surface of the piston plate 8, with the upper end of the pull rod 3 located outside the cylindrical body 1.

[0018] Furthermore, a through groove is provided at the top of the cylinder 1, through which the tie rod 3 passes and is fitted with a clearance fit.

[0019] In this embodiment, the cover 2 is placed over the opening of the glass container and pressed down to ensure a tight fit between the cover 2 and the glass container, preventing air leakage. Then, the lever 3 is pulled, causing the piston plate 8 to move upward, thereby drawing the gas from the glass container into the cylinder 1. If there are no cracks on the surface of the glass container, the inside of the glass container is in a vacuum state, and the air bladder 4 will expand. If there are cracks on the surface of the glass container, the air pressure inside the glass container is normal, and the air bladder 4 will not change. Therefore, this application can determine whether there are cracks on the surface of the glass container by observing the expansion state of the air bladder 4. The detection method is relatively intuitive, simple to operate, and has wide applicability.

[0020] Furthermore, a spring 9 is fitted on the outer surface of the pull rod 3. The upper end of the spring 9 is fixedly connected to the inner surface of the cylinder 1, and the lower end of the spring 9 is fixedly connected to the piston plate 8.

[0021] In this embodiment, by setting a spring 9, the spring 9 is compressed during the upward movement of the pull rod 3. After use, the compressed spring 9 extends and can drive the piston plate 8 to reset, so that the piston plate 8 moves to the bottom of the cylinder 1.

[0022] Furthermore, multiple sets of annular slots 6 of different sizes are provided on the lower surface of the cover 2.

[0023] In this embodiment, multiple sets of annular slots 6 of different sizes are used to accommodate glassware of different sizes.

[0024] Furthermore, a baffle 11 is fixedly connected to the lower end of the connecting rod 10, the airbag 4 is set as a ring and sleeved on the bottom of the connecting rod 10, and the bottom of the airbag 4 is fixedly connected to the baffle 11. A detector 5 is fixedly connected to the connecting rod 10 at the position above the airbag 4.

[0025] Detector 5 can be a touch sensor, a technology widely used in daily life. Its operation is not detailed here, but it can provide convenience and innovation in many scenarios. This type of sensor can detect the contact between an object and its surface. In this embodiment, when the airbag 4 inflates, the top of the airbag 4 moves upward and touches the detector 5. The detector 5 can then emit a signal indicating that the detected glassware is a qualified product.
