[0002] Neutral borosilicate glass tubes have an important impact in pharmaceutical, chemical and laboratory applications. They are characterized by extremely high chemical stability and thermal stability. In the pharmaceutical field, neutral borosilicate glass tubes are widely used in drug packaging, especially injection bottles and ampoules. These glass tubes can effectively prevent chemical reactions between drugs and containers, ensuring the effectiveness and safety of drugs. The safety and effectiveness of drugs largely depend on the sealing performance of their packaging materials. Therefore, neutral borosilicate glass tubes have good sealing properties, which is a guarantee of drug safety and effectiveness.

[0003] In the existing technology, the traditional neutral borosilicate glass tube sealing performance detection device is mainly composed of a vacuum pump, a pressure gauge, a clamp and a control system. The sealing performance of the glass tube is judged by vacuuming and monitoring the pressure changes.

[0004] However, when the traditional neutral borosilicate glass tube sealing performance detection device is used, only a single neutral borosilicate glass tube can be detected each time, which causes the problem of low detection efficiency. Therefore, the utility model proposes a sealing performance detection device for neutral borosilicate glass tube production to solve the above problem. Utility Model Content

[0024] Example 1: Please refer to Figures 1 to 4 The utility model provides a technical solution: a device for detecting the sealing performance of neutral borosilicate glass tubes in production, the device comprising: a control device 1, an operating screen 2 is provided on the surface of the control device 1, and a vacuum pump 3 is connected to the side of the control device 1;

[0025] An inspection chamber 4 is provided with a placement rack 8 inside the inspection chamber 4. A fixing plate 5 is provided at one end of the placement rack 8. A plurality of placement holes 6 are opened on the surface of the fixing plate 5. A sealing cover 7 is provided at the upper end of the inspection chamber 4. The sealing cover 7 is connected to a vacuum pump 3.

[0026] During use, several neutral borosilicate glass tubes can be placed in the placement holes 6 on the surface of the fixing plate 5, and then the placement rack 8 can be placed in the detection chamber 4, and an appropriate amount of water can be poured into the detection chamber 4, and the water can cover the neutral borosilicate glass tubes. Then, the detection chamber 4 can be sealed as a whole through the sealing cover 7, and then the operation screen 2 on the surface of the operation control device 1 can be used to make the vacuum pump 3 act on the detection chamber 4. The pressure in the detection chamber 4 is reduced by the action of the vacuum pump 3. When the pressure in the detection chamber 4 is reduced, if the sealing of the glass tube is poor, bubbles will continue to emerge. If the sealing of the glass tube is good, there will be no change, thereby realizing the detection of multiple glass tubes, thus avoiding the problem of low detection efficiency.

[0027] Example 2: Based on Example 1, in order to enable the detection device to detect multiple glass tubes simultaneously, a placement rack 8 is provided. The placement rack 8 is fixedly connected to the fixing plate 5 at one end close to the sealing cover 7. The other end of the placement rack 8 is provided with a bottom plate 18. A limit plate 19 is provided between the bottom plate 18 and the fixing plate 5. The limit plate 19 is fixedly installed in the placement rack 8. A plurality of limit holes are opened on the surface of the limit plate 19. The limit holes correspond to the placement holes 6 one by one. Handles are provided on both sides of the placement rack 8.

[0028] Before testing, multiple glass tubes can be inserted into the placement holes 6 . Under the action of the limiting plate 19 and the fixing plate 5 , the glass tubes are stably placed in the placement rack 8 , and then the placement rack 8 is placed in the testing chamber 4 as a whole.

[0029] Example 3: Based on Example 2, in order to facilitate the detection of the sealing of the glass tube, a detection chamber 4 is provided with an overall cylindrical structure, the bottom of the detection chamber 4 is stuck in the limit frame, and the limit frame is fixedly installed on the surface of the control device 1;

[0030] A stabilizing plate 13 is provided on the bottom surface of the vacuum pump 3, an interface 14 is provided on the top of the vacuum pump 3, a soft rubber hose 15 is inserted into the interface 14, an adapter 11 is provided on the rear side of the vacuum pump 3, a connecting line 12 is provided in the adapter 11, and a handle is fixedly installed on the top of the vacuum pump 3;

[0031] A support rod 9 is provided at the bottom of the control device 1, and a suction cup 10 is provided at one end of the support rod 9. Adapters 11 are provided on both sides of the control device 1. A connecting line 12 is provided in the adapter 11 on the side close to the vacuum pump 3;

An adapter 11 is provided on the other side of the pull rod 16. A sensor line 17 is provided in the adapter 11. One end of the sensor line 17 is connected to the adapter 11 on the side of the control device 1 away from the vacuum pump 3.

[0033] During testing, the control device 1 is used to operate the vacuum pump 3 to act on the testing chamber 4. The testing chamber 4 is made of transparent material so that the internal situation can be viewed from the outside. Under the action of the sealing cover 7, the testing chamber 4 is in a sealed state as a whole. Under the action of the vacuum pump 3, the overall pressure in the testing chamber 4 is reduced. At this time, if the overall sealing of the glass tube is good, there will be no reaction. If there is a problem with the sealing, bubbles will emerge, which makes it easier to detect the sealing of the glass tube.

[0034] Working principle: In actual use, several neutral borosilicate glass tubes can be placed in the placement holes 6 on the surface of the fixed plate 5, and then the placement rack 8 is placed in the detection chamber 4, and an appropriate amount of water is poured into the detection chamber 4, and the water covers the neutral borosilicate glass tubes. Then, the detection chamber 4 is sealed as a whole through the sealing cover 7, and then the operation screen 2 on the surface of the operation control device 1 is used to make the vacuum pump 3 act on the detection chamber 4. The pressure in the detection chamber 4 is reduced by the action of the vacuum pump 3. When the pressure in the detection chamber 4 is reduced, if the sealing of the glass tube is poor, bubbles will continue to emerge. If the sealing of the glass tube is good, there will be no change, thereby realizing the detection of multiple glass tubes, thus avoiding the problem of low detection efficiency.

[0035] Although the 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 variations may be made to these embodiments without departing from the principles and spirit of the present invention, and the scope of the present invention is defined by the appended claims and their equivalents.
