Description

Technical Field

[0001] This utility model relates to the field of sealing test device technology, and more specifically, it relates to a vacuum testing device for injectable cephalosporin products. Background Technology

[0002] In modern industrial production, the sealing performance of a product is one of the key factors determining its quality, reliability, safety, and service life, especially in fields such as pharmaceutical packaging, automotive parts, semiconductor packaging, precision instruments, and aerospace. These applications often have extremely stringent requirements for leakage rates. To meet the growing demand for high-precision, high-efficiency, and non-destructive testing, micro-leakage sealing testing technology has emerged and continues to develop. The core of this technology lies in utilizing high-precision sensors to accurately detect and quantify minute leakage channels in products.

[0003] Existing micro-leakage sealing testers typically place the sample to be tested into a fixture first, and then use a vacuum pump to remove air from the fixture. This eliminates the need for operators to place the sample in water and determine the sealing performance by counting the number of air bubbles. However, during use, there is no clamping mechanism between the upper cover and the lower seat of the fixture, resulting in air leakage at the edges during the test. Furthermore, when the equipment is used for continuous testing, the vacuum pump generates heat, which is conducted to the fixture through the base. At this time, the expansion of the metal fixture changes the volume of the accommodating cavity, causing test errors.

[0004] Therefore, a new solution is needed to address this problem. Utility Model Content

[0005] In view of the shortcomings of the existing technology, the purpose of this utility model is to provide a vacuum detection device for injectable cephalosporin products.

[0006] The above-mentioned technical objective of this utility model is achieved through the following technical solution: a vacuum detection device for injectable cephalosporin products, comprising a base, a clamp assembly, and a control panel. The clamp assembly includes an upper clamp and a lower clamp. The lower clamp has a downward-facing cavity on its top surface. The upper clamp covers the lower clamp and is used to close the cavity. The lower clamp has a downward-facing groove on its top surface. The inner diameter of the groove is larger than the outer diameter of the cavity. The inner wall of the groove is provided with symmetrically arranged sealing gaskets. The upper clamp has an insert. When the upper clamp covers the lower clamp, the insert is inserted into the groove and the sealing gasket abuts against the outer wall of the insert.

[0007] The present invention is further configured such that: the insert is detachably connected to the bottom surface of the upper clamp, a limiting groove is provided on the bottom surface of the upper clamp, a limiting plate is provided at the opening of the limiting groove, the limiting plate and the upper clamp are fixed by bolts, and when the limiting plate is fixed to the upper clamp, the limiting plate is flush with the bottom surface of the upper clamp.

[0008] The present invention is further configured such that: the insert includes an insertion part and a limiting part; the limiting groove can accommodate the insertion of the limiting part; an elastic element is provided between the bottom surface of the limiting part and the limiting groove; when the limiting plate is fixed to the upper clamp, the limiting part abuts against the top surface of the limiting plate and the elastic element is in a compressed state.

[0009] The present invention is further configured such that: the elastic element is a compression spring, the length of the compression spring is greater than the depth of the limiting groove, and several columns are provided on the bottom of the limiting groove and the limiting part, and the two ends of the compression spring are respectively sleeved on two symmetrically arranged columns.

[0010] The present invention is further configured such that: the insertion part and the limiting part are integrally formed, the cross-section of the insertion part is L-shaped, and a plurality of the columns are arranged in an array along the length direction of the limiting groove.

[0011] The present invention is further configured such that: the base is also provided with a vacuum pump, a ventilation pipe and a sealing joint, the two ends of the ventilation pipe are respectively connected to the sealing joint and the vacuum pump, the lower clamp is provided with a through groove communicating with the storage cavity, the sealing joint is sealed and installed in the through groove, and when the lower clamp and the sealing joint are fixed, there is a gap between the lower clamp and the base.

[0012] The present invention is further configured such that: a fixing component is provided at the connection between the lower clamp and the sealing joint, the fixing component includes two fixing hoops, one end of the two fixing hoops is rotatably connected to each other, and the other end is fixed by bolts.

[0013] The present invention is further configured such that the length of the insertion part is greater than the depth of the limiting groove.

[0014] In summary, this utility model has the following beneficial effects: By setting a sealing gasket in the groove of the lower clamp and using the insert of the upper clamp to abut against the sealing gasket, the sealing between the upper cover and the lower clamp is ensured, effectively solving the air leakage problem and ensuring the accuracy of the test. By setting an elastic element, when the upper clamp falls, the elastic element can play a buffering role, avoiding damage to the upper clamp and extending the service life of the clamp. By setting a fixing hoop, the lower clamp is suspended on the base, preventing the base from conducting heat to the clamp and ensuring the stability of the volume of the storage cavity, thereby ensuring the accuracy and reliability of the test.

They are only for the convenience of describing this utility model and do not indicate that the device referred to must have a specific orientation or operate in a specific orientation. Therefore, they should not be construed as limitations on this utility model.

[0027] Unless otherwise defined, all technical and scientific terms used herein have the same meaning as commonly understood by one of ordinary skill in the art to which this application belongs. The terminology used herein is for the purpose of describing particular embodiments only and is not intended to be limiting of the application.

[0028] The present invention will now be described in detail with reference to the accompanying drawings and embodiments.

[0029] A vacuum detection device for injectable cephalosporin products, such as Figure 1 As shown, the system includes a base 1, a clamp assembly 2, and a control panel 11. The clamp assembly 2 is located on the top surface of the base 1, and the control panel 11 is located on the side wall of the base 1. Specifically, the clamp assembly 2 includes an upper clamp 21 and a lower clamp 22. The top surface of the lower clamp 22 has a downward-facing storage cavity 221. The upper clamp 21 covers the lower clamp 22 and is used to seal the storage cavity 221. The base 1 is also equipped with a vacuum pump 12, a ventilation pipe, and a sealing joint 13. The two ends of the ventilation pipe are connected to the sealing joint 13 and the vacuum pump 12, respectively. The lower clamp 22 has a through groove 224 communicating with the storage cavity 221. The sealing joint 13 is sealed and installed in the through groove 224. When the lower clamp 22 is fixed with the sealing joint 13, there is a gap between the lower clamp 22 and the base 1. During testing, the operator first separates the upper clamp 21 and the lower clamp 22, and then places the object to be tested... The sample to be tested is placed in the storage cavity 221, and then the upper clamp 21 is placed on the lower clamp 22. The operator then turns on the vacuum pump 12 through the control panel 11 and tests the sample in the storage cavity 221. The data is fed back to the display screen of the base 1 for the operator to read. By setting the through groove 224 and the sealing joint 13, and sealing the joint 13 in the through groove 224, the air pipe and the storage cavity 221 are sealed together, which avoids gas leakage during vacuum testing and ensures the accuracy and reliability of the test. When the lower clamp 22 is fixed with the sealing joint 13, there is a gap between the lower clamp 22 and the base 1. The gap setting can effectively prevent the heat of the base 1 from being conducted to the lower clamp 22, thereby preventing the clamp from expanding due to the heat of the base 1, which would affect the stability of the volume of the storage cavity 221.

[0030] The lower clamp 22 has a groove 222 with its top surface facing downwards. The inner diameter of the groove 222 is larger than the outer diameter of the storage cavity 221. Symmetrically arranged sealing gaskets 223 are provided on the inner wall of the groove 222. The upper clamp 21 has an insert 211. When the upper clamp 21 closes the lower clamp 22, the insert 211 is inserted into the groove 222, and the sealing gaskets 223 press against the outer wall of the insert 211. The elastic deformation of the sealing gaskets 223 effectively fills the tiny gap between the insert 211 and the groove 222, thus significantly enhancing the sealing performance between the clamps. The symmetrical arrangement of the sealing gaskets 223 further ensures the uniformity of the sealing effect. This increases the contact area between the sealing gasket 223 and the insert 211, improving the sealing performance and avoiding air leakage caused by poor local sealing, thereby ensuring the reliability and accuracy of the testing process. Furthermore, one end of the insert 211 is uniformly provided with annular protrusions 216, and the sealing gasket 223 is provided with annular grooves to accommodate the annular protrusions. When the operator inserts the insert between the two sealing gaskets 223, the annular protrusions 216 are embedded in the annular grooves, thereby improving the connection strength between the insert 211 and the sealing gasket 223 and ensuring the stability of the upper clamp 21 and the lower clamp 22 when they are fixed.

[0031] Specifically, the insert 211 includes an insertion part 2111 and a limiting part 2112, and the insert 211 is detachably connected to the bottom surface of the upper clamp 21. A limiting groove 212 is provided on the bottom surface of the upper clamp 21, and the limiting groove 212 can accommodate the insertion of the limiting part 2112. A limiting plate 213 is provided at the opening of the limiting groove 212. The limiting plate 213 and the upper clamp 21 are fixed together by bolts. When the limiting plate 213 is fixed to the upper clamp 21, the limiting plate 213 is flush with the bottom surface of the upper clamp 21. By setting the limiting groove 212... The limiting plate 213 ensures the accurate positioning of the insert 211 during installation and provides stable mechanical support. The tight fit between the limiting plate 213 and the limiting part 2112 prevents the insert 211 from loosening or shifting during use, thereby ensuring the sealing performance of the fixture and the accuracy of equipment detection. The bolt-fixed design of the limiting plate 213 also facilitates the operator's disassembly and assembly, making it easy to remove the insert 211 and replace it when it is damaged.

[0032] Furthermore, an elastic element 214 is provided between the limiting part 2112 and the bottom surface of the limiting groove 212. The elastic element 214 is a compression spring, and the length of the compression spring is greater than the groove depth of the limiting groove 212. Several columns 215 are provided on the bottom of the limiting groove 212 and on the limiting part 2112. The two ends of the compression spring are respectively sleeved on two symmetrically arranged columns 215. When the upper plate 213 is fixed to the upper clamp 21, the limiting part 2112 abuts against the top surface of the limiting plate 213 and the elastic element 214 is in a compressed state. The design of the compression spring ensures that when the insert 211 is subjected to external impact or vibration, such as when the upper clamp 21 falls from a height, the insert 2111 will contact the ground first. The compression spring can effectively buffer the impact force and reduce the direct impact on the insert 211 and the upper clamp 21, thereby protecting the clamp assembly 2 from damage. At the same time, during the vacuum detection process, the equipment will be affected by mechanical vibration or other external forces. The presence of the elastic element 214 can absorb these forces. This reduces vibration energy, decreases the impact of vibration on detection accuracy, and improves the stability and reliability of detection. By setting several columns 215 and correspondingly setting two columns 215 with concave and convex fits, the two ends of the compression spring are respectively sleeved on the corresponding two columns 215, which improves the stability of the compression spring. Furthermore, the insertion part 2111 and the limiting part 2112 are integrally formed. The integrally formed structure can withstand greater mechanical stress, which improves the stability and reliability of the insertion part 211 during use. Several columns 215 are arranged in an array along the length direction of the limiting groove 212, so that the elastic force of the compression spring can be evenly distributed between the insertion part 211 and the limiting groove 212. The cross-section of the insertion part 211 is L-shaped and the length of the insertion part 2111 is greater than the groove depth of the limiting groove 212, so that the insertion part 2111 can be fully inserted into the groove 222, ensuring that the insertion part 211 and the sealing gasket 223 in the groove 222 are tightly fitted.

[0033] A fixing component 14 is provided at the connection between the lower clamp 22 and the sealing joint 13. The fixing component 14 includes two fixing hoops 141. One end of the two fixing hoops 141 is rotatably connected to each other, and the other end is fixed by bolts. By setting the fixing hoops 141, the connection strength between the lower clamp 22 and the sealing joint 13 is improved, preventing loosening or falling off due to external force or vibration. The bolt fixing method is simple and quick to operate. The connection or disassembly of the lower clamp 22 and the sealing joint 13 can be completed by simply tightening or loosening the bolts, which shortens the installation and disassembly time and improves work efficiency. Furthermore, the fixing component 14 also includes a fixing protrusion ring 142. The fixing protrusion ring 142 is installed on the top surface of the fixing hoops 141. A positioning groove 225 is opened on the bottom surface of the lower clamp 22 to accommodate the insertion of the fixing protrusion ring 142. When the fixing protrusion is embedded in the positioning groove 225, the lower clamp 22 and the sealing joint 13 are firmly connected, ensuring the stability of the clamp component 2 when testing the sealing performance of the sample.

[0034] Working process: The operator first separates the upper clamp 21 and the lower clamp 22 to expose the placement cavity 221. Then, the sample to be tested is placed into the placement cavity 221. After placement, the insert 211 of the upper clamp 21 is aligned with the groove 222 of the lower clamp 22 and inserted. After insertion, the annular protrusion 216 on the insert 211 abuts against the inner wall of the annular groove on the sealing gasket 223, improving the sealing performance of the equipment. Then, the operator starts the vacuum pump 12 through the control panel 11. The vacuum pump 12 starts working, and the air is supplied through the ventilation pipe and the sealing joint. 13. Extract the air from the storage cavity 221 to create a vacuum environment and perform testing. After the test is completed, the operator turns off the vacuum pump 12 through the control panel 11, opens the upper clamp 21, and takes out the sample to complete the product sealing test. When the equipment needs to be replaced or repaired, loosen the bolts on the two fixing clamps 141 and move them down along the sealing joint 13 to separate the fixing protrusion 142 from the positioning groove 225. Then, rotate the two fixing clamps 141 in the opposite direction to remove them from the sealing joint 13. When reinstalling, the operation is reversed.

All technical solutions falling within the scope of this utility model's concept are protected. It should be noted that for those skilled in the art, any improvements and modifications made without departing from the principle of this utility model should also be considered within the protection scope of this utility model.
