Obviously, the described embodiments are only a part of the embodiments of the present invention, and not all embodiments, and other embodiments obtained by those skilled in the art without inventive labor based on the embodiments of the present invention all belong to the protection scope of the present invention.

In addition, all the connection relations mentioned herein do not mean that the components are directly connected, but mean that a better connection structure can be formed by adding or reducing connection accessories according to the specific implementation situation. The utility model provides an each technical feature can the interactive combination under the prerequisite of conflict each other.

As shown in fig. 1, an air tightness detecting device includes a frame 10, the frame 10 is provided with a plurality of conveying rollers 20 for conveying heat exchangers, the plurality of conveying rollers 20 are arranged along a horizontal direction, the plurality of conveying rollers 20 are connected with a driving motor through a chain or a transmission belt, and under the driving of the motor, the conveying rollers 20 rotate to convey the heat exchangers.

For the convenience of carrying out airtight detection and reducing the problem that the transport heat exchanger brought simultaneously, this embodiment makes frame 10 be provided with the support frame 30 that supports the heat exchanger and drives the first power part 40 that support frame 30 goes up and down, and support frame 30 sets up between a plurality of conveying rollers 20, and the top of support frame 30 is provided with air inlet connector 50 and gives vent to anger and connects 60, and air inlet connector 50 and air outlet connector 60 are used for connecting the heat exchanger, and air inlet connector 50 and air outlet connector 60 pass through the pipe connection airtight detector.

This embodiment sets up the support frame 30 and drives the first power part 40 that support frame 30 rose through conveying roller 20 department at the transport heat exchanger, thereby, when needs carry out airtight detection, can use support frame 30 to promote the heat exchanger on the conveying roller 20, then make the heat exchanger be connected with air inlet connector 50 and air outlet connector 60, carry out airtight detection, accomplish airtight detection back, support frame 30 descends, conveying roller 20 carries the heat exchanger again, need not make a round trip to remove the heat exchanger, just also reduced the produced problem of transport round trip, reduce and fall the damage, reduce the incident risk.

In some embodiments, the supporting frame 30 may be provided with a plurality of first bars 31, the plurality of first bars 31 are arranged in parallel with the conveying roller 20, and the tops of the plurality of first bars 31 abut against the heat exchanger. It is preferable that the first bar 31 is alternately arranged with the feed roller 20, so that heat exchangers of different length specifications are inspected and it is advantageous that the heat exchangers are kept stable on the first bar 31.

In addition, the arrangement of the first rod piece 31 can also reduce the contact between the support frame 30 and the heat exchanger, avoid the surface of the heat exchanger from being scratched, and effectively protect the appearance of the heat exchanger.

In some embodiments, a plurality of the first rods 31 are rotatably connected to the supporting frame 30.

After the improvement, the first rod piece 31 is rotatably connected with the support frame 30, so that the obstruction of the first rod piece 31 to the heat exchanger conveying can be reduced, the heat exchanger can be conveniently moved to the support frame 30, the heat exchanger can be conveniently removed from the support frame 30, and the normal conveying is not influenced.

In some embodiments in which a first lever 31 is provided, the end of said first lever 31 is provided with a transmission wheel which can be brought into abutment with the conveyor roller 20.

When the support frame 30 descends, the driving wheel abuts against the conveying roller 20, so that the first rod piece 31 is driven to rotate, the first rod piece 31 drives the heat exchanger to convey, and collision of adjacent heat exchangers is avoided.

In some embodiments, the frame 10 may be provided with a screw 70, the screw 70 is disposed in an up-and-down direction, the screw 70 is disposed on the top of the supporting frame 30, the bottom of the screw 70 is provided with a bracket 80, and the air inlet joint 50 and the air outlet joint 60 are disposed on the bracket 80.

The height of adjusting screw 70 is passed through to this embodiment for the height position of air inlet joint 50 and air outlet joint 60 can be adjusted, therefore, can detect the heat exchanger product of difference, of course, also conveniently compresses tightly heat exchanger and joint fine setting back, ensures sealedly.
