Description

Technical Field

[0001] This patent relates to the field of airtightness testing, specifically a bottle airtightness testing device. Background Technology

[0002] The air tightness tester enables direct pressure difference leak detection, provides intuitive test results, and has a high performance-price ratio. It is commonly used to test medicine bottles, wine bottles, and other similar items.

[0003] The air tightness tester mainly consists of two parts: the testing equipment and the desktop fixture. The desktop fixture is equipped with a mold that has a sealing cavity identical to the bottle to be tested. During the test, the bottle is placed in the sealing cavity, and then the mold is closed. The testing equipment pressurizes the sealing cavity with gas, and then the gas source is cut off. The gas pressure is observed to see if it drops, thereby achieving the purpose of air tightness testing.

[0004] However, the desktop fixtures in existing airtightness testers require frequent maintenance of the guide columns to prevent jamming during sliding, which is quite cumbersome.

[0005] Therefore, an airtightness testing device with automatic maintenance is proposed. Utility Model Content

[0006] In view of the shortcomings of the existing technology, the purpose of this patent is to provide a bottle airtightness detection device.

[0007] The technical solution adopted by this patent to solve its technical problem is: a bottle airtightness testing device, including an airtightness tester and a desktop fixture. The airtightness tester and the desktop fixture are electrically connected. A guide column is installed on the worktable of the desktop fixture. An upper pressure plate is slidably installed on the outer side of the guide column. An upper mold is installed on the lower wall of the upper pressure plate. A lower mold is installed on the worktable of the desktop fixture. The lower mold is located directly below the upper mold. Sealing cavities are opened on the upper wall of the lower mold and the lower wall of the upper mold.

[0008] A connecting ring is installed on the lower wall of the upper pressure plate, and a sponge sleeve is installed on the inner side of the connecting ring. Both the connecting ring and the sponge sleeve are sleeved on the outer side of the guide post.

[0009] A spring is sleeved on the outer side of the guide post. A placement ring is installed on the upper wall of the spring. An annular groove is formed on the upper wall of the placement ring. The annular groove is filled with lubricating oil. The sponge sleeve can be inserted into the annular groove.

[0010] Furthermore, the desktop fixture is equipped with clamping plates on both the left and right sides, and a protective plate is slidably installed between the two clamping plates, which can shield the workbench of the desktop fixture.

[0011] Furthermore, it also includes a bottle body, which is placed in a sealed cavity on the upper wall of the lower mold.

[0012] Furthermore, the protective plate has a positioning hole on its side wall, into which a pin is inserted and installed; the desktop fixture has a slot on its side wall, into which the pin can be inserted.

[0013] Furthermore, a retaining ring is installed on the inner wall of the annular groove.

[0014] Furthermore, a handle is installed on the side wall of the protective plate, and the protective plate is a transparent acrylic sheet.

[0015] The beneficial effects of this patent are:

[0016] This device uses a connecting ring and a sponge sleeve on the outside of the guide column in the desktop fixture. The sponge sleeve absorbs lubricating oil, so when the upper pressure plate moves under the drive of the electric push rod, the sponge sleeve lubricates the guide column, allowing the device to automatically perform maintenance during operation, which is very convenient.

[0017] In addition, a retaining ring is installed above the placement ring in this device to prevent the lubricating oil inside the placement ring from spilling and to keep the workbench of the desktop fixture clean. Attached Figure Description

[0021] The present patent is further illustrated below with reference to specific embodiments. It should be understood that these embodiments are for illustrative purposes only and are not intended to limit the scope of the patent. Furthermore, it should be understood that after reading the teachings of this patent, those skilled in the art can make various alterations or modifications to this patent, and these equivalent forms also fall within the scope defined by the appended claims.

[0022] See Figure 1 , Figure 2This is a schematic diagram of the structure of this patent. A bottle air tightness testing device includes an air tightness tester 1 and a desktop fixture 2. The air tightness tester 1 and the desktop fixture 2 are electrically connected. A guide column 3 is installed on the worktable of the desktop fixture 2. An upper pressure plate 4 is slidably installed on the outer side of the guide column 3. An upper mold 5 is installed on the lower wall of the upper pressure plate 4. A lower mold 6 is installed on the worktable of the desktop fixture 2. The lower mold 6 is located directly below the upper mold 5. Both the upper wall of the lower mold 6 and the lower wall of the upper mold 5 have sealing cavities 7.

[0023] The air tightness tester 1 and desktop fixture 2 proposed in this paper are both existing technologies. The model of the air tightness tester 1 is LS4000. When the test is performed, after the bottle 16 is placed in the sealing cavity 7, the air tightness tester 1 will control the electric push rod in the desktop fixture 2 to push it down, so that it closes the upper mold 5 and the lower mold 6. Then it will pressurize the sealing cavity 7. At this time, the display screen in the air tightness tester 1 will display the air pressure in the sealing cavity 7 in real time. By observing the change in air pressure, it can be determined whether there is a leak in the bottle 16.

[0024] A connecting ring 8 is installed on the lower wall of the upper pressure plate 4, and a sponge sleeve 9 is installed on the inner side of the connecting ring 8. Both the connecting ring 8 and the sponge sleeve 9 are sleeved on the outer side of the guide post 3.

[0025] A spring 10 is sleeved on the outside of the guide post 3. A placement ring 11 is installed on the upper wall of the spring 10. An annular groove 12 is opened on the upper wall of the placement ring 11. Lubricating oil 13 is filled in the annular groove 12. The sponge sleeve 9 can be inserted into the annular groove 12.

[0026] This device uses a sponge sleeve 9 installed below the upper pressure plate 4. When the sponge sleeve 9 absorbs the lubricating oil 13, it can lubricate and maintain the guide column 3 during the movement of the upper pressure plate 4, eliminating the need to wipe the guide column 3 separately, which is very convenient.

[0027] When the upper mold 5 and the lower mold 6 are closed, the sponge sleeve 9 is inserted into the annular groove 12 to absorb the lubricating oil 13 in the annular groove 12.

[0028] The desktop fixture 2 is equipped with a clamping plate 14 on both the left and right sides, and a protective plate 15 is slidably installed between the two clamping plates 14. The protective plate 15 can cover the workbench of the desktop fixture 2.

[0029] The existing desktop fixture 2 does not have a protective structure on its worktable. When not in use, prolonged exposure can cause external dust to easily enter the sealed cavity 7 of the mold, which can affect the test results. Therefore, this device is equipped with a protective plate 15, which can cover the worktable of the desktop fixture 2 when the device is not in use, thus preventing the entry of external dust.

[0030] It also includes a bottle body 16, which is placed in a sealed cavity 7 on the upper wall of the lower mold 6.

[0031] The protective plate 15 has a positioning hole 17 on its side wall, and a pin 18 is inserted into the positioning hole 17. The desktop tool 2 has a slot 19 on its side wall, and the pin 18 can be inserted into the slot 19.

[0032] When using this device, the protective plate 15 can be slid upwards using handle 21, and then the pin 18 can be inserted into the slot 19 to fix the position of the protective plate 15. (See attached document.) Figure 1 The anti-slip plate 15 is in the open state. In this state, the protective plate 15 is located above the workbench of the desktop fixture 2 and will not interfere with the operation of the staff.

[0033] A retaining ring 20 is installed on the inner wall of the annular groove 12;

[0034] The retaining ring 20 can block the lubricating oil 13 and prevent the lubricating oil 13 from flowing out of the annular groove 12.

[0035] The protective plate 15 is equipped with a handle 21 on its side wall and is made of transparent acrylic sheet.

[0036] In operation, the protective plate 15 is first opened, and then the position of the protective plate 15 is fixed by the cooperation between the pin 18 and the slot 19. Then, the bottle 16 to be tested is placed into the sealing cavity 7. Then, the electric push rod in the desktop tooling 2 is pushed down by the air tightness tester 1 to close the upper mold 5 and the lower mold 6. Then, air is injected into the sealing cavity 7 and pressurized. At this time, the display screen in the air tightness tester 1 will display the air pressure in the sealing cavity 7 in real time. By observing the change in air pressure, it can be determined whether there is a leak in the bottle 16.

[0037] During the process of the electric push rod driving the upper pressure plate 4 to move, the sponge sleeve 9 can lubricate and maintain the guide post 3, so that the guide post 3 does not need to be wiped separately, which is very convenient.
