Description

Technical Field

[0001] This utility model relates to the technical field of sealing test equipment, and in particular to a sealing test equipment for testing finished air freshener products. Background Technology

[0002] Air fresheners are products we use every day, and these products also need to undergo sealing tests. Usually, a sealing tester is used for the test. The sealing tester requires placing the product to be tested in a test chamber that is to be evacuated. Vacuum sensor technology is used to monitor the vacuum changes in the test chamber over a predetermined test period. Changes in absolute vacuum and relative vacuum imply leaks and defects in the packaging.

[0003] The sealing performance testing device for finished stainless steel welded pipes disclosed in Chinese Patent CN212513468U, after studying the prior art and the aforementioned patent, reveals that the inner diameter of the experimental chamber at the top of the sealing tester is fixed, limiting its application to bottles of only one diameter. Furthermore, the experimental chamber is fixed with screws, making replacement inconvenient. Therefore, this utility model proposes a sealing performance testing device for fixed-size air freshener products. Utility Model Content

[0004] The purpose of this invention is to at least solve one of the aforementioned technical defects.

[0005] The purpose of this invention is to overcome the shortcomings of the prior art, solve the problems mentioned in the background art, and provide a sealing test device for testing finished air freshener products.

[0006] The purpose of this utility model is achieved through the following technical solution: a sealing test device for testing a fixed freshener product, including a base platform, a linear module is provided on the top of the base platform, an adjustment plate is fixedly connected to the output end of the linear module, a connecting plate is provided on the top of the adjustment plate, an experimental chamber is fixedly connected to the top of the connecting plate, a limit block is fixedly connected to the side of the experimental chamber near the top, a positioning ring is attached to the top of the limit block, a test can is snapped into the inside of the positioning ring, and a through hole is opened inside the positioning ring;

[0007] A spring is fixedly connected to the top of the connecting plate, and a support plate is fixedly connected to the top of the spring. An air pipe is provided inside the connecting plate, and the air pipe has a spring tube.

[0008] Preferably, threaded holes are provided at the four corners of the top of the adjusting plate, and connecting screws are threaded to the four corners of the connecting plate. The connecting screws are threaded into the inside of the threaded holes, and the connecting plate is fixedly connected to the adjusting plate by the connecting screws.

[0009] By adopting the above technical solution, the connecting plate is connected to the adjusting plate as a whole by connecting screws.

[0010] Preferably, vertical rods are fixedly connected to the four corners of the base near the adjustment plate, and sealing plates are sleeved on the outer surface of the vertical rods. An electric push rod is fixedly connected to the top of the sealing plate.

[0011] By adopting the above technical solution, the electric push rod can adjust the distance between the sealing plate and the experimental chamber.

[0012] Preferably, a support leg is fixedly connected to the top of the base, and the main body of the device is fixedly connected to the top of the support leg. The electric push rod is fixedly connected to the inside of the main body of the device. A display is fixedly connected to one side of the main body of the device. An inclined surface is provided on the front side of the base. Switch buttons are provided on both the left and right sides of the inclined surface, and a pause button is provided at the center of the inclined surface.

[0013] By adopting the above technical solution, both switch buttons need to be pressed simultaneously with both hands to avoid keeping hands under the sealing plate.

[0014] Preferably, the number of limiting blocks is three, and the three limiting blocks are welded to the inner wall of the experimental cavity in a circumferential array. The through holes are circular holes, and the number of through holes is several, with the several through holes arranged in a circumferential array inside the positioning ring.

[0015] By adopting the above technical solution, positioning rings with different inner diameters can define detection tanks of different diameters.

[0016] Preferably, the spring is a compression spring, the support plate is a circular plate, the diameter of the support plate is smaller than the inner diameter of the experimental cavity, and the diameter of the spring is adapted to the diameter of the support plate.

[0017] By adopting the above technical solution, the sealing plate presses the test can into the experimental chamber for testing. After the test is completed, when the spring is decompressed and reset, a part of the test can can be pushed out of the experimental chamber through the support plate, making it convenient for staff to remove the test can from the experimental chamber.

[0018] Compared with the prior art, the present invention has the following advantages:

[0019] 1. This sealing test equipment for the fixed freshener product testing, by setting a positioning ring, has a limit block fixedly connected to the side of the experimental chamber near the top. The top of the limit block is covered with a positioning ring. The positioning ring has a through hole inside. The positioning ring with an inner diameter that matches the diameter of the test can be selected. First, the positioning ring is placed on the limit block on the inner wall of the experimental chamber. Then, the test can is fitted into the inside of the positioning ring. The through hole in the positioning ring does not affect the normal vacuum test of the experimental chamber. Test cans of different diameters can be tested without replacing the experimental chamber.

[0020] 2. This sealing test equipment for the finished product testing of the air freshener uses a spring. The top of the connecting plate is fixedly connected to the spring, and the top of the spring is fixedly connected to the support plate. The spring is a compression spring, and the support plate is a round plate. In use, the test can be placed on the support plate, and then the electric push rod is started in the forward direction to push the sealing plate towards the test can. The sealing plate completely presses the test can into the experimental chamber for testing. The spring is compressed and contracts, but does not fully contract, so it does not affect the normal vacuum test. After the test is completed, when the spring is decompressed and reset, a part of the test can be pushed out of the experimental chamber through the support plate, making it easy for the staff to remove the test can from the experimental chamber.
