In addition, the terms "first" and "second" are only used to distinguish in the description and have no special meaning.

[0031] Please refer to the following Figures 1 to 3 The specific structure of the airtightness detection device of the utility model is described.

[0032] The utility model discloses an airtightness detection device, which includes a fixed seat 100, a movable member 200, a blocking member 300 and a driving member 400. The movable member 200 is slidably mounted on the fixed seat 100 along a first direction (vertical direction), a slide groove 210 is provided on the movable member 200, the blocking member 300 is connected to the movable member 200 and is used to block the container to be detected, a blowing channel 301 is provided on the blocking member 300, and the blowing channel 301 can blow external gas into the container to be detected, and the driving member 400 is mounted on the fixed seat 100, and the driving member 400 has a driving part 410 that moves along a second direction (horizontal direction), and the driving part 410 is matched with the slide groove 210. When the driving member 400 drives the driving part 410 to slide along the second direction, the driving part 410 can slide in the slide groove 210 to drive the movable member 200 to move along the first direction.

[0033] It is understandable that, in the actual working process, the airtightness detection device is installed on the transport line of the container to be detected. When the container to be detected moves to the bottom of the blocking member 300, the driving member 400 is started, and when the driving part 410 is driven to slide, the driving part 410 can slide in the slide groove 210 to drive the movable part 200 to move downward and insert into the opening position of the container to be detected. Since the blocking member 300 is provided with a blowing channel 301, the blowing channel 301 can blow external gas into the container to be detected. When the external gas enters the container to be detected, the container to be detected can be tested for airtightness. After the test is completed, the driving member 400 drives the driving part 410 to move in the opposite direction, and the blocking member 300 leaves the container to be detected and waits for the next test. Therefore, the airtightness detection device of the utility model blocks the container to be detected by the blocking member 300 and faces the container to be detected to realize the airtightness test. The test results of this test method are reliable, stable and repeatable, and no human intervention is required during the entire test process, and the degree of automation is high.

[0034] It should be noted here that, in actual use, there are many ways to install the airtightness detection device on the transportation line of the container to be tested, for example, using screws and other connecting parts to fix the fixing base 100 to the transportation line, and using a snap-on structure to fix the fixing base 100 to the transportation line, etc. The method of installing the airtightness detection device on the transportation line of the container to be tested can be adjusted according to actual needs.

[0035] refer to Figure 1 As shown, the driving member 400 also includes a driving source 420, and the driving part 410 includes a driving wheel. The driving source 420 can drive the driving wheel to move along the second direction, and the driving wheel is rotatably connected to the power output end of the driving source 420. It can be understood that the driving part 410 includes a driving wheel, which can ensure that the driving wheel slides stably and smoothly in the slide groove 210, thereby ensuring that the blocking member 300 can be stably lifted and lowered. In this embodiment, the driving source 420 is a cylinder, and the driving wheel is a ball bearing. Of course, in other embodiments of the utility model, the driving source 420 can also select an electric push rod according to actual needs, and the driving wheel can also be a rolling wheel or other structures.

[0036] refer to Figure 1As shown, the slide slot 210 includes a first slot 211, a second slot 212 and a third slot 213 connected in sequence, the first slot 211 and the third slot 213 are arranged at intervals along the first direction, and the second slot 212 is arranged at an angle. It can be understood that in the actual working process, when the driving wheel slides in the first slot 211 and the third slot 213, the blocking member 300 stops moving, and when the driving wheel slides in the second slot 212, the blocking member 300 will rise and fall. Therefore, the sliding of the driving wheel in the third slot 213 can ensure that the blocking member 300 remains at a specified height, thereby ensuring that the blocking member 300 is stably inserted into the container to be tested. When the driving wheel slides in the first slot 211, the blocking member 300 can be kept at a specified height to avoid the phenomenon that the movable member 200 hits other components due to excessive travel of the blocking member 300.

[0037] refer to Figure 1 As shown, the airtightness detection device also includes a guide assembly 500, which is installed between the fixed seat 100 and the movable member 200 and is used to guide the movable member 200 to move along the first direction. It can be understood that, according to the foregoing, during the airtightness detection process, when the movable member 200 moves in the vertical direction, it drives the blocking member 300 to block or open the opening of the container to be detected. If the movement direction of the movable member 200 is skewed, the blocking member 300 will also be skewed, resulting in a phenomenon of loose sealing, which reduces the accuracy of the airtightness detection. In this embodiment, the additional guide assembly 500 can limit the movement direction of the movable member 200, prevent the movable member 200 from being skewed, ensure that the movable member 200 can stably drive the blocking member 300 to move along the first direction, ensure the sealing effect of the blocking member 300 on the container to be detected, and thus ensure the accuracy of the airtightness detection.

[0038] Further, the guide assembly 500 includes a slide rail 510 and a slider 520 matched with the slide rail 510, the slide rail 510 is extended along the first direction, the slide rail 510 is installed on the fixed seat 100, and the slider 520 is installed on the movable member 200. It can be understood that during the movement of the movable member 200, the slider 520 moves along the slide rail 510. Since the guide effect of the slide rail 510 on the slider 520 can ensure that the movable member 200 can only move along the first direction, it is ensured that the movable member 200 can stably drive the blocking member 300 to move along the first direction, and improve the sealing effect of the blocking member 300 on the container to be tested, thereby ensuring the accuracy of the airtightness test. In an alternative embodiment, the slide rail 510 is installed on the movable member 200, and the slider 520 is installed on the fixed seat 100.

[0039] Of course, in other embodiments of the present invention, the guide assembly 500 may also include a guide sleeve and a guide column, the guide sleeve is arranged on the fixed seat 100, and the guide column is arranged on the movable part 200, and is not limited to the matching structure of the slider 520 and the slide rail 510 of this embodiment.

[0040] Optionally, the guide components 500 are arranged in pairs, and the two guide components 500 arranged in pairs are located on both sides of the slide slot 210. It can be understood that by setting two guide components 500, and the two guide components 500 arranged in pairs are located on both sides of the slide slot 210, the movement direction of the movable member 200 is guided by the two guide components 500, which can improve the restriction on the movement direction of the movable member 200, further ensure that the movable member 200 can stably drive the blocking member 300 to move along the first direction, and further improve the sealing effect of the blocking member 300 on the container to be tested, thereby ensuring the accuracy of the airtightness test.

[0041] refer to Figure 2 As shown, the plugging member 300 includes a connecting portion 310, a venting portion 320 and a plugging portion 330 which are connected in sequence, the connecting portion 310 is connected to the movable member 200, the plugging portion 330 is used to plug the container to be tested, the blowing channel 301 is provided at the venting portion 320 and the plugging portion 330, and the venting portion 320 is connected to the gas connector 600, and the gas connector 600 is used to connect to an external gas source. It can be understood that the connecting portion 310 can ensure the stable connection between the plugging member 300 and the movable member 200, and the gas connector 600 is provided on the venting portion 320 to ensure that the plugging member 300 is relatively stably connected to the external gas source, so that the gas can be stably blown into the container to be tested during the air tightness test.

[0042] Optionally, the blowing channel 301 includes a first channel 3011 and a second channel 3012 that are connected. The first channel 3011 is arranged along a first direction to penetrate the blocking portion 330 and a portion of the ventilation portion 320. The second channel 3012 is arranged at an angle to the first channel 3011 and is arranged on the ventilation portion 320. The gas connector 600 is inserted into an end of the second channel 3012 away from the first channel 3011 and stops at the outer wall of the ventilation portion 320. It can be understood that, through the first channel 3011 and the second channel 3012, it can be ensured that the connection between the gas connector 600 and the sealing member 300 will not affect the normal transportation of the container to be tested, thereby ensuring that the air-tightness test can be carried out smoothly. The gas connector 600 is inserted into the end of the second channel 3012 away from the first channel 3011 and stops on the outer wall of the ventilation portion 320. On the one hand, it facilitates the connection between the gas connector 600 and the sealing member 300, and on the other hand, it ensures the sealing of the connection between the gas connector 600 and the sealing member 300, avoids the occurrence of air leakage, thereby ensuring the accuracy of the air-tightness test.

[0043] Further optionally, in order to improve the sealing performance of the connection between the gas connector 600 and the sealing member 300 , a sealing ring may be provided or a sealant may be applied at the connection position between the two.

[0044] Optionally, the airtightness detection device further includes a sealing member 700, which is sleeved on the blocking portion 330 and abuts against a side of the vent portion 320 facing the blocking portion 330. It is understandable that, in the actual detection process, after the blocking portion 330 is inserted into the container to be detected, the sealing member 700 is pressed against the top of the container to be detected by the vent portion 320, and the sealing member 700 can enhance the blocking effect of the blocking member 300 on the container to be detected, avoid air leakage, and thus ensure the accuracy of the airtightness detection.

[0045] Optionally, the upper end of the connecting portion 310 is provided with a threaded portion, and the movable member 200 is provided with a threaded hole that matches the threaded portion. It is understandable that in the actual installation process, it is only necessary to insert the connecting portion 310 into the threaded hole and then rotate it, which is very convenient for installation and removal. Of course, in other embodiments of the utility model, the connecting portion 310 and the movable member 200 can also be connected by other connection methods such as bonding or welding, and are not limited to the threaded connection of this embodiment.
