Description

Technical Field

[0001] This utility model relates to the technical field of food packaging leakage detection device structure, and in particular to a food packaging leakage detection device. Background Technology

[0002] Food packaging is an integral part of food products and one of the main processes in the food industry. It protects food from damage caused by biological, chemical, and physical external factors during its distribution from the factory to the consumer. It also helps maintain the stable quality of the food itself. It facilitates the consumption of food and is the first thing consumers notice about the food's appearance, attracting them to the market. It has value beyond material cost. The food packaging leakage detection device refers to the residual oxygen meter, which is an analytical instrument used to test the residual oxygen content in nitrogen-filled and modified atmosphere packaged foods and nitrogen-filled pharmaceuticals.

[0003] Existing food packaging leak detection devices have certain drawbacks in use. When the probe of the residual oxygen meter in the traditional food packaging leak detection device is inserted into the food packaging, the insertion angle is not close to vertical enough. The residual oxygen meter is not stable when it is moved vertically downward. In addition, the gas inside the food packaging will escape from the probe insertion hole, resulting in inaccurate test results. Utility Model Content

A protective sleeve 2 is movably installed at the lower end of the residual oxygen detector 1, and a probe 3 is fixedly installed at the lower end of the residual oxygen detector 1. A display screen 4 is embedded and fixedly installed on the front surface of the residual oxygen detector 1 near the upper end. A three-way bracket 5 is fitted on the outer side of the protective sleeve 2, and a sealing sleeve 6 is fixedly installed at the lower end of the protective sleeve 2. A power button 7 is located on the front surface of the residual oxygen detector 1 near the lower end of the display screen 4, a direction key 8 is located on the front surface of the residual oxygen detector 1 near the lower end, an exit button 9 is located on the front surface of the residual oxygen detector 1 near the middle, and an confirm button 10 is located on the front surface of the residual oxygen detector 1 near the middle. The three-way bracket 5 enables the residual oxygen detector 1 to move vertically and stably, making the insertion of the probe 3 into the food packaging more stable and the angle closer to vertical, reducing the error in food packaging leak detection, adapting to food packaging of different sizes, and easy to assemble and disassemble. The sealing sleeve 6 seals the food packaging when testing the oxygen content, preventing gas from escaping from the inside of the food packaging when testing the oxygen content.

[0024] The three-way frame 5 includes a chassis 501, a guide rail frame 502, an inner sliding plate 503, a spring telescopic rod 504, rubber feet 505, a fixing post 506, a first spring 507, a pressure disc 508, and a rubber pad 509. The chassis 501 is fitted onto the outside of the protective sleeve 2. The guide rail frame 502 is fixedly installed on the outside of the chassis 501. The inner sliding plate 503 is located inside the guide rail frame 502. Three guide rail frames 502 are installed, evenly distributed on the outside of the chassis 501. The spring telescopic rod 504 is fixedly installed on the lower surface of the inner sliding plate 503 at the end away from the chassis 501. The rubber feet 505 are fixedly installed on the lower end of the spring telescopic rod 504, and the lower surface of the rubber feet 505 has a groove. The fixing post... 506 is fixedly installed on the upper surface of the inner slide plate 503 near the front end. Spring 507 is sleeved on the outside of the fixed post 506. Pressing disc 508 is fixedly installed on the lower end of spring 507. Rubber pad 509 is fixedly installed on the lower surface of pressing disc 508. The upper end of the fixed post 506 passes through the opening of the guide frame 502.

The first spring 507 outside the fixing post 506 presses down against the circular plate 508, causing the lower surface of the rubber pad 509 to tightly adhere to the upper surface of the guide rail frame 502, restricting the movement of the inner sliding plate 503. During testing, hold the residual oxygen detector 1 and press down to compress the spring telescopic rod 504 until the probe 3 is inserted into the food packaging. The base 501 can then be removed from the protective sleeve 2. The three-way frame 5 allows the residual oxygen... The detector 1 can move vertically and smoothly, making the insertion of probe 3 into the food packaging more stable and the angle closer to vertical, reducing the error in detecting air leakage in the food packaging. It is adaptable to food packaging of different sizes and is easy to assemble and disassemble. In the sealing sleeve 6, during the insertion of probe 3 into the food packaging, a layer of water is applied to the lower surface of the second disc 603. The second spring 602 between the first disc 601 and the second disc 603 is compressed, causing the rubber suction cup 604 to firmly press against the surface of the food packaging. The sealing sleeve 6 serves to seal the food packaging when testing the oxygen content, preventing the gas inside the food packaging from escaping when testing the oxygen content.
