Description

Technical Field

[0001] This utility model belongs to the field of airtightness testing technology, specifically relating to a suspended bottle airtightness leak detection stand. Background Technology

[0002] In the production process of container bottles, the bottle body is often formed by welding. After the bottle body is welded, it is necessary to test its airtightness. Among the methods of airtightness testing, some involve filling the bottle body with gas at a specified pressure and observing the change in pressure after standing for a period of time to test the airtightness. Other methods involve filling the bottle body with gas and then immersing it in water, observing the bubble situation in the water to test the airtightness.

[0003] Currently, airtightness testing often involves manual inspection of each bottle, creating a bottleneck in the testing process. To address this, we propose a suspended bottle airtightness testing bench, designed and manufactured based on the aforementioned underwater testing method. This bench can simultaneously test the airtightness of multiple bottles, improving testing efficiency. Summary of the Invention

[0004] The purpose of this invention is to provide a suspended bottle airtightness leak detection stand to solve the problems existing in the background art.

[0005] To achieve the above-mentioned technical objectives, the technical solution adopted by this utility model is as follows: A suspended bottle airtightness leak detection stand includes a rectangular test pool. A suspension frame is provided on one side of the rectangular test pool. The suspension frame includes a base plate, two placement plates, and multiple fixed supports. The base plate is located below the rectangular test pool, and a rotating shaft is fixedly connected to the bottom of the base plate. Both ends of the rotating shaft rotatably pass through the rectangular test pool. The two placement plates are arranged vertically and vertically and have multiple placement slots that match the bottle. The base plate and the two placement plates are fixed together by the multiple fixed supports. The suspension frame is also equipped with a leak detection mechanism, which includes an air inlet pipe and multiple pressure testing valves. The air inlet pipe is fixedly installed to the base plate, and one end of the air inlet pipe is connected to a test air source. Each of the pressure testing valves is installed at equal intervals on the air inlet pipe, with the valve port of each pressure testing valve facing upwards. Each pressure testing valve is also equipped with an elastic sealing ring on the side of the valve port. A flipping mechanism is provided between the rectangular test pool and both ends of the rotating shaft. The suspension frame is also equipped with a clamping mechanism.

[0006] As a further limitation of the present invention, the flipping mechanism includes: a mounting frame, which is fixedly mounted to the rectangular test pool; a driving cylinder, which is vertically arranged with its telescopic end facing downward, and the top of the driving cylinder is hinged to the mounting frame; and a first connecting rod, one end of which is fixedly mounted to the rotating shaft, and the other end of which is hinged to the telescopic end of the driving cylinder.

[0007] As a further limitation of the present invention, the number of fixed brackets is at least three, and one fixed bracket is respectively provided at each end of the base plate.

[0008] As a further limitation of the present invention, the clamping mechanism includes two mounting sleeves, two transverse guide rails, a longitudinal slide rod, and multiple clamping blocks. The two mounting sleeves are slidably fitted onto the upper ends of the two fixed brackets located at both ends of the base plate, and the mounting sleeves and the fixed brackets are detachably connected by bolts. The two transverse guide rails are respectively transversely fixed to the two mounting sleeves. The two ends of the longitudinal slide rod are slidably connected to the two transverse guide rails, and the multiple clamping blocks are all installed at the bottom of the longitudinal slide rod.

[0009] As a further limitation of the present invention, a protective net is provided on the side of the rectangular test pool away from the suspension frame. The protective net is slidably connected to the upper side of the rectangular test pool, and the rectangular test pool is also provided with a protective net driving mechanism.

[0010] As a further limitation of the present invention, the protective net driving mechanism includes two electric telescopic rods, which are respectively installed and fixed on both sides of the rectangular test pool. The telescopic ends of the two electric telescopic rods are installed and fixed to both sides of the protective net through a second connecting rod.

[0011] Before testing, the rectangular test pool is filled with water. During bottle testing, the clamping mechanism is first removed, and then the bottles to be tested are placed mouth-down into the placement slots of the placement plate, so that the valve of the pressure testing valve is inserted into the bottle mouth. The bottle mouth then contacts the elastic sealing ring on the side of the valve. The clamping mechanism is then moved back to press the upper side of the bottle, so that the bottle mouth abuts against the elastic sealing ring to seal the bottle mouth. This completes the installation and sealing of the bottles. After installation, gas is introduced into the inlet pipe through the test gas source. The gas then enters the bottle to be tested through the pressure testing valve. The flipping mechanism is then activated, causing the bottles mounted on the suspension frame to flip into the rectangular test pool, immersing each bottle in the pool. The air bubbles in the rectangular test pool indicate whether the airtightness of each bottle is good. This invention can test the airtightness of multiple bottles with a single machine, improving the efficiency of the testing operation and overcoming the bottleneck of manual testing.

Detailed Implementation

[0014] To enable those skilled in the art to better understand this utility model, the technical solution of this utility model will be further described below in conjunction with the accompanying drawings and embodiments. Example

[0015] like Figures 1 to 4 The suspended bottle leak testing stand shown includes a rectangular test pool 100. A suspension frame 110 is provided on one side of the rectangular test pool 100. The suspension frame 110 includes a base plate 111, two placement plates 112, and multiple fixed supports 113. The base plate 111 is located below the rectangular test pool 100, and a rotating shaft 1111 is fixedly connected to the bottom of the base plate 111. Both ends of the rotating shaft 1111 rotatably pass through the rectangular test pool 100. The two placement plates 112 are arranged vertically and together have multiple placement slots 11 that match the bottle body. 21. The base plate 111 and the two placement plates 112 are fixed together by multiple fixing brackets 113. By connecting and fixing the fixing brackets 113, the base plate 111 and the placement plates 112 can be fixed into a whole to form the entire suspension frame 110. The placement slot 1121 opened by the upper and lower placement plates 112 can position the bottle. And through the pivot 1111 set at the bottom of the base plate 111, the entire suspension frame 110 can rotate relative to the rectangular test pool 100. The suspension frame 110 is also equipped with a leak detection mechanism, which includes an air inlet pipe 120 and multiple test valves 121. The air inlet pipe 120 is fixedly installed on the base plate 111, and one end of the air inlet pipe 120 is connected to a test air source. Each test valve 121 is installed at equal intervals on the air inlet pipe 120, with the valve port of each test valve 121 facing upward. Each test valve 121 is also equipped with an elastic sealing ring 1211 on the side of the valve port. A flipping mechanism is provided between the rectangular test pool 100 and both ends of the rotating shaft 1111. The suspension frame 110 is also equipped with a clamping mechanism.

[0016] Before testing, fill the rectangular test pool 100 with water. When testing the bottles, first remove the clamping mechanism, and then place the bottles to be tested, mouth down, into the placement slots 1121 of the placement plate 112, so that the valve port of the pressure test valve 121 is inserted into the bottle mouth. The bottle mouth then contacts the elastic sealing ring 1211 on the side of the valve port of the pressure test valve 121. Then, move the clamping mechanism back to press the upper side of the bottle, so that the bottle mouth abuts against the elastic sealing ring 1211 to seal the bottle mouth. This completes the installation and sealing of the bottles. After the bottle is installed, gas is introduced into the air inlet pipe 120 through the test gas source. The gas then enters the bottle to be tested through the pressure test valve 121. Subsequently, the flipping mechanism is activated, which causes the bottle to be tested mounted on the suspension bracket 110 to flip into the rectangular test pool 100, so that each bottle to be tested is submerged in the rectangular test pool 100. In this way, the air tightness of each bottle to be tested can be judged by the bubbles in the rectangular test pool 100.

[0017] This invention can test the airtightness of multiple bottles with a single machine, improving the efficiency of the testing operation and overcoming the bottleneck of manual testing one by one.

[0018] As a structural description of the flipping mechanism in this embodiment, such as Figure 1 and Figure 2 As shown, the flipping mechanism includes: a mounting frame 130, which is fixedly mounted to the rectangular test pool 100; a drive cylinder 131, which is vertically arranged with its telescopic end facing downward, and the top of the drive cylinder 131 is hinged to the mounting frame 130; and a first connecting rod 132, one end of which is fixedly mounted to the rotating shaft 1111, and the other end of which is hinged to the telescopic end of the drive cylinder 131.

[0019] When the flipping mechanism is in use, the drive cylinder 131 installed on the mounting bracket 130 is activated, causing the telescopic end of the drive cylinder 131 to extend downward, driving the first connecting rod 132 to flip downward, thereby causing the rotating shaft 1111 to rotate and flip the suspension bracket 110 into the rectangular test pool 100. At the same time, since the top of the drive cylinder 131 is hinged to the mounting bracket 130 and the first connecting rod 132 is hinged to the telescopic end of the drive cylinder 131, the drive cylinder 131 and the first connecting rod 132 will move adaptively without jamming when the flipping mechanism is in use.

[0020] As a structural description of the clamping mechanism in this embodiment, such as Figures 2 to 4 As shown, the number of fixed brackets 113 includes at least 3, and one fixed bracket 113 is provided at each end of the base plate 111. The clamping mechanism includes two mounting sleeves 140, two transverse guide rails 141, one longitudinal slide rod 142, and multiple clamping blocks 143. The two mounting sleeves 140 are slidably fitted onto the upper ends of the two fixed brackets 113 located at both ends of the base plate 111, and the mounting sleeves 140 and the fixed brackets 113 are detachably connected by bolts. The two transverse guide rails 141 are respectively transversely fixed to the two mounting sleeves 140. The two ends of the longitudinal slide rod 142 are slidably connected to the two transverse guide rails 141, and the multiple clamping blocks 143 are all installed at the bottom of the longitudinal slide rod 142.

[0021] When installing the bottle, such as Figure 2As shown, sliding the longitudinal slide bar 142 to the side of the transverse guide rail 141 causes the clamping mechanism to be misaligned, allowing the bottle to be placed into the placement slot 1121 with the bottle opening facing down. Then, moving the longitudinal slide bar 142 back causes the clamping block 143 at the bottom of the longitudinal slide bar 142 to press the upper side of the bottle. At this time, as shown... Figure 3 and Figure 4 As shown, this allows the bottle opening to fit tightly against the elastic sealing ring 1211, thus sealing the bottle. Meanwhile, the mounting sleeve 140 and the fixed bracket 113 are slidably fitted together and detachably connected by bolts. When pressing bottles of different heights, the height of the pressing mechanism can be adjusted by adjusting the mounting sleeve 140 to press the bottle. Example

[0022] This embodiment is a functional optimization based on Embodiment 1, mainly aimed at avoiding excessive water splashing during the flipping process. The optimized structure is as follows: Figure 5 As shown, a protective net 150 is also provided on the side of the rectangular test pool 100 away from the suspension bracket 110. The protective net 150 is slidably connected to the upper side of the rectangular test pool 100. The rectangular test pool 100 is also provided with a protective net driving mechanism, which includes two electric telescopic rods 151. The two electric telescopic rods 151 are respectively installed and fixed on both sides of the rectangular test pool 100. The telescopic ends of the two electric telescopic rods 151 are installed and fixed to both sides of the protective net 150 through the second connecting rod 152.

[0023] After the bottle is installed and sealed during the test, before the suspension frame 110 is flipped, the second link 152 is driven by two electric telescopic rods 151 to move, so that the protective net 150 moves toward the rectangular test pool 100 to cover the rectangular test pool. Then the suspension frame 110 is flipped. The water splashed during the flipping of the suspension frame 110 in the rectangular test pool 100 can be blocked by the protective net 150 to avoid splashing too much water.

[0024] The above embodiments are merely illustrative of the principles and effects of this utility model and are not intended to limit the scope of this utility model. Any person skilled in the art can modify or alter the above embodiments without departing from the spirit and scope of this utility model. Therefore, all equivalent modifications or alterations made by those skilled in the art without departing from the spirit and technical concept disclosed in this utility model should still be covered by the claims of this utility model.
