[0021] The technical solution of the present invention is further described below with reference to the accompanying drawings and embodiments.

[0022] like Figures 1 to 5 As shown, an embodiment of the utility model proposes an airtightness detection tooling for automobile air conditioners, which includes a water tank 1, a gantry 101 is provided on one side of the interior thereof; a detection device, including two groups of sealed boxes 2 located in the water tank 1, the two sealed boxes 2 are connected by an adjustment device, and the adjustment device is used to adjust the relative distance between the two sealed boxes 2, one of the sealed boxes 2 is provided with an air pipe 202, the air pipe 202 is connected to an external inflation device, and the two sealed boxes 2 are respectively used to clamp the two ends of the air conditioning pipe body 100; a driving device is provided on the gantry 101, and is transmission-connected to the detection device, and is used to drive the detection device to rise and fall.

[0023] The detailed working process of this embodiment is as follows: the adjustment device is used to adjust the relative distance between the two sealed boxes 2 to meet the requirements of testing air-conditioning pipes of different lengths. The position of the two sealed boxes 2 is controlled by the driving device, so that they rise and fall in the water storage tank 1 so that they can be immersed in water. The two sealed boxes 2 clamp the ends of the air-conditioning pipe and form a sealed state. Then, they are connected to the external inflation device through the air pipe 202, and the sealed boxes 2 are inflated by the external inflation device. During this process, since the two sealed boxes 2 and the air-conditioning pipe are both immersed in water, the quality of the air-conditioning pipe being tested can be determined by observing whether bubbles are generated in the water. The two sealed boxes 2 can clamp the ends of multiple air-conditioning pipes, allowing multiple pipes to be inspected at one time, thereby improving inspection efficiency.

[0024] like Figure 4 As shown, each sealed box 2 is provided with an opening, and a slide groove 204 is provided at both ends of the opening. A movable block 206 is slidably provided in the slide groove 204. A control component for driving the movable block 206 to open and close is provided on the sealed box 2. Rubber pads 205 are provided on the movable block 206 and the lower end of the opening. Multiple groups of one-to-one corresponding arc grooves 203 are provided on the two rubber pads 205, wherein the two rubber pads 205 abut against each other under the drive of the control component.

[0025] like Figure 4 and Figure 5 As shown, each control component includes a control disk 5 and a control shaft 503 fixedly set on the control disk 5, a mounting block 505 is fixedly set on the sealing box 2, the control disk 5 is rotatably set on the mounting block 505, a drive ring 207 is fixedly set on the movable block 206, and the control shaft 503 is located in the drive ring 207.

[0026] The detailed working process of this embodiment is as follows: the arc groove 203 on the rubber pad 205 is used to clamp the air-conditioning pipe and ensure its air-tightness during the clamping process. When in use, the ends of the air-conditioning pipe to be tested are placed in the arc groove 203 of the rubber pad 205 corresponding to the open end of the sealing box 2, and then the control disk 5 is rotated to control the movable block 206 to slide in the slide groove 204, so that the two rubber pads 205 are pressed against each other until they are in a sealed state. When the air-conditioning pipe needs to be removed, the control disk 5 can be rotated in the opposite direction.

[0027] The two sealing boxes 2 can detect at least one air conditioning pipe. If the number of detected air conditioning pipes is less than the number of arc-shaped grooves 203, the remaining arc-shaped grooves 203 can be blocked.

[0028] like Figure 3 As shown, the adjustment device includes connecting frames 4 fixedly arranged on both sides of any one sealed box 2 , and sliding grooves 201 are arranged on both sides of the other sealed box 2 , and each connecting frame 4 passes through the corresponding sliding groove 201 .

[0029] The detailed working process of this embodiment is as follows: under the setting of the connecting frame 4, a sealed box 2 can be movably set on the connecting frame 4 through the sliding groove 201, so that it can be away from or close to another sealed box 2 to meet the requirements of testing air-conditioning pipes of different lengths.

[0030] like Figure 2 and Figure 3 As shown, the driving device includes two screws 3 threadedly connected to the corresponding connecting frames 4. One end of the thread of the two screws 3 is rotatably set in the water tank 1, and the other end is rotatably set on the gantry 101. A driving source 302 is fixedly set on the gantry 101, and a transmission shaft 303 is rotatably set. The transmission shaft 303 is transmission-connected to the output end of the driving source 302. Both ends of the transmission shaft 303 and the end of the two screws 3 close to the gantry 101 are provided with bevel gears 301, which are engaged with the corresponding bevel gears 301.

[0031] The detailed working process of this embodiment is as follows: the driving source 302 is used to drive the two screws 3 to rotate, and the rotation of the two screws 3 can drive the connecting frame 4 to rise and fall. During operation, the driving source 302 drives the transmission shaft 303 to rotate, and then the bevel gear 301 on the transmission shaft 303 drives the two screws 3 to rotate synchronously in the same direction, which can drive the connecting frame 4 and its two sealed boxes 2 to descend into the water in the water tank 1. When it needs to be lifted, the driving source 302 can be controlled to rotate in the opposite direction.

[0032] The driving source 302 in this embodiment is a motor. In other embodiments, a suitable driving component can be selected according to time requirements.

[0033] like Figure 5 As shown, a limit seat 501 is provided on the peripheral wall of the control panel 5, and a first limit column 502 and a second limit column 504 are provided on the corresponding sealing box 2. The first limit column 502 and the second limit column 504 are located on both sides of the corresponding control panel 5, wherein the limit seat 501 abuts against the first limit column 502 or the second limit column 504.

[0034] The detailed working process of this embodiment is as follows: the function of the first limit column 502 or the second limit column 504 is to limit the control disk 5, indirectly controlling the upper limit position and the lower limit position of the movable block 206, to prevent it from rotating on its own during the force process, affecting its use. When the control disk 5 rotates to the limit seat 501 and abuts against the first limit column 502, it is the lower limit position of the movable block 206. At this time, the two rubber pads 205 abut against each other to form a sealed state. In this position, the extension line of the interaction force between the movable block 206 and the control shaft 503 on the control disk 5 passes through the center of the control disk 5, forming a dead point to ensure the sealing when clamping the air-conditioning pipe. When the control disk 5 rotates to the limit seat 501 and abuts against the second limit column 504, it is the upper limit position of the movable block 206, which is convenient for installing the air-conditioning pipe.

[0035] like Figure 2 As shown, a protective cover 102 is provided on the gantry 101 , and each bevel gear 301 is located in the protective cover 102 .

[0036] The detailed working process of this embodiment is as follows: the function of the protective cover 102 is to protect the helical gears 301 inside it.

[0037] like Figure 3 As shown, a limiting plate 401 is provided at one end of each connecting frame 4 close to the sliding slot 201 .

[0038] The detailed working process of this embodiment is as follows: the function of the limiting plate 401 is to prevent the sealing box 2 from sliding out of the connecting frame 4 when the sealing box 2 is slid, thereby preventing the sealing box 2 from falling.

[0039] The implementation principle of the embodiment of the present application is: first, control the driving source 302 to rotate and drive the two sealing boxes 2 to the upper side of the water tank 1, and then place the ends of the air-conditioning pipes to be tested in the arc grooves 203 of the rubber pads 205 corresponding to the open ends of the sealing boxes 2 in turn, and then rotate the control disk 5 to control the movable block 206 to slide in the slide groove 204, so that the two rubber pads 205 are pressed against each other until they are in a sealed state, and then control the driving source 302 to rotate in the opposite direction, drive the sealing box 2 into the water in the water tank 1, and then inflate the sealing box 2 through an external inflation device. By observing whether bubbles are generated in the water, the quality of the air-conditioning pipe being tested can be judged.

[0040] Finally, it should be noted that the above embodiments are only used to illustrate the technical solution of the utility model and are not limiting. Although the utility model is described in detail with reference to the preferred embodiments, ordinary technicians in this field should understand that the technical solution of the utility model can be modified or replaced by equivalents without departing from the purpose and scope of the technical solution of the utility model, which should be included in the scope of the claims of the utility model.
