A water inlet and a water outlet are symmetrically provided on one side of the glass plate 14. When the partition is pressed by the pressing device 7 and limited by the telescopic device 12, water is introduced through the water inlet. When the water height is higher than the height of the partition, bubbles appear when observing the partition welding position through the glass plate. When the observation is completed, the water in the carrying box 11 is discharged through the water outlet.

A pressing assembly for pressing the partition into the glass plate 14 is provided on one side of the glass plate 14;

A limiting assembly for limiting the sliding range of the pressing assembly is provided on one side of the glass plate 14 .

Two threaded holes a are symmetrically formed on the mounting frame 1 , and threaded holes b are formed on the two fixing blocks 3 . The threaded holes a and b are coaxially distributed and threadedly connected by fixing bolts 4 .

There are a plurality of telescopic devices 12, which are divided into two groups. The two groups of telescopic devices 12 are symmetrically distributed on both sides of the inner side of the carrying box 11 along the length direction.

A controller is provided in each telescopic device 12 , and a pressure-sensitive element is provided on the output end of each telescopic device 12 . The controller and the pressure-sensitive element are electrically connected.

The protective cover 13 and the telescopic device 12 correspond one to one. The protective cover 13 is sleeved on the outer peripheral surface of the output end of the telescopic device 12. When the partition is compressed by the clamping device 7, the partition is limited by multiple telescopic devices 12. The telescopic device 12 can limit the partitions of different shapes through the control of the pressure-sensitive element and the controller. In addition, through the setting of the protective cover 13, the telescopic device 12 can effectively protect the partition while limiting the partition.

Embodiment 2

As shown in FIGS. 1-3 , the utility model proposes a partition leak testing device. Compared with the first embodiment, this embodiment further specifically discloses the specific structure of the limit assembly and the clamping assembly.

In this embodiment, the limiting assembly includes a mounting frame 1, a slide rail 8, a slider 9 and a limiting block 15;

There are two slide rails 8, which are symmetrically mounted on one side of the mounting frame 1 facing the carrying box 11;

Limit blocks 15 are installed at both ends of each slide rail 8 facing the carrying box 11. The two limit blocks 15 and the slide rail 8 form a sliding limit member, and the projection of the sliding limit member is in the shape of a Chinese character "凵";

The sliders 9 correspond to the slide rails 8 one by one. The sliders 9 are slidably connected to the slide rails 8 and are vertically distributed with the slide rails 8 .

The clamping assembly includes a mounting plate 2, a fixing block 3, an air pump 5, a pneumatic telescopic rod 6, a pressing device 7 and a connecting rod 10;

The fixed end of the air pump 5 is connected to the upper end surface of the mounting plate 2, one end of the pneumatic telescopic rod 6 passes through the mounting plate 2 and is connected to the output end of the air pump 5, and the other end of the pneumatic telescopic rod 6 is connected to one end of the pressing device 7;

Two connecting rods 10 are symmetrically mounted on the outer circumference of the pressing device 7, and the other ends of the two connecting rods 10 are rotatably connected to the other ends of the two sliders 9 respectively;

Two fixing blocks 3 are symmetrically installed on both sides of the mounting plate 2. The two fixing blocks 3 are detachably connected to the mounting frame 1. A clamping assembly and a limiting assembly are installed on one side of the carrying box 11. The air pump 5 controls the pneumatic telescopic rod 6 to descend and drives the clamping device 7 to press down. At this time, the slide rail 8 and the limiting block 15 in the limiting assembly cooperate to limit the clamping device through the connection between the connecting rod 10 and the slider 9, so that the partition can be stably pressed in the carrying box 11 for air tightness inspection.

In summary, in the present invention, the partition is first placed in the carrying box 11, and the air pump 5 is turned on to drive the pneumatic telescopic rod 6 to descend. When the pneumatic telescopic rod 6 descends, the pressing device 7 is driven to descend. The two connecting rods 10 of the pressing device 7 are rotatably connected with the slider 9. The slider 9 is limited by the slide rail 8 and slides on the slide rail 8, thereby driving the pressing device 7 to press down linearly to press the partition;

At this time, the telescopic device 12 is controlled to extend forward, and the pressure-sensitive element transmits an electrical signal to the controller when it touches the outer peripheral surface of the partition. The controller controls the telescopic device 12 to stop extending, thereby limiting the partition. The protective cover 13 can protect the telescopic device 12 from damaging the outer surface of the partition when it is extended, thereby limiting the partition.

After the partition is limited and pressed and limited in the carrying box 11, water is introduced through the water inlet. When the water level is higher than the height of the partition, bubbles appear when observing the partition welding position through the glass plate 14. When the observation is completed, the water in the carrying box 11 is discharged through the water outlet to complete the entire air tightness test process.

The implementation modes of the present invention are described in detail above in conjunction with the accompanying drawings, but the present invention is not limited thereto, and various changes can be made within the knowledge scope of technicians in the relevant technical field without departing from the purpose of the present invention.
