[0019] The following will further describe the present utility model in detail with reference to the embodiments given in the drawings.
[0020] Refer to Figure 1 One Figure 7As shown in the figure, the adjustable air-conditioning pressure plate sealing detection device of this embodiment includes a frame 1 and a detection groove 11 provided on the frame 1. There is water in the detection groove 11. The frame 1 is provided with a reference plate 12 above the detection groove 11. A lifting cylinder 2 is provided on the reference plate 12. The lifting cylinder 2 is connected to a detection frame 3. The detection frame 3 is located above the detection groove 11. A number of upwardly protruding lower detection columns 4 are provided on the lower side of the detection frame 3. The lower detection columns 4 are hollow. An upper stop ring 41 is provided at the upper end of the lower detection column 4. A lower closing piece 42 is provided in the lower detection column 4. A rotatable lower driven button 43 is provided on the upper stop ring 41. The lower driven button 43 abuts against the lower closing piece 42. A closing cylinder 31 is provided on the upper side of the detection frame 3. The closing cylinder 31 is connected to a closing plate 32. An upper detection column 5 is provided on the closing plate 32. The upper detection column 5 is hollow. An upper stop ring 51 is provided at the lower end of the upper detection column 5. An upper closing piece 52 is provided in the upper detection column 5. A rotatable upper driven button 53 is provided on the upper stop ring 51. The upper driven button 53 abuts against the upper closing piece 52. The upper detection column 5 and the lower detection column 4 are connected to an external detection cylinder through a hose. A spring 44 is provided in the lower detection column 4. The spring 44 abuts against the lower closing piece 42 and the detection frame 3.
[0021] Through the above technical solution, specifically, the edges of the upper closing piece 52 and the lower closing piece 42 have positioning buttons that abut against the upper detection column 5 and the lower detection column 4, so that the positions of the upper closing piece 52 and the lower closing piece 42 are stable during the lifting process.
[0022] There are several groups of lower detection columns 4 and upper detection columns 5, which respectively correspond to air-conditioning pressure plates and pipeline parts of different models.
[0023] Before detection, the lifting air cylinder 2 drives the detection frame 3 to rise, so that the detection frame 3 is located above the water surface in the detection groove 11. Then, according to the models of the automotive air-conditioning pressing plate and the pipeline parts, they are installed in the detection frame 3. The installation process is as follows: First, insert the lower pipeline into the lower detection column 4. At this time, the automotive air-conditioning pressing plate and the pipeline parts are in a vertical state. Then, the closing air cylinder 31 operates, driving the closing plate 32 to descend, so that the upper detection column 5 and the pipeline at the upper end of the automotive air-conditioning pressing plate and the pipeline parts are inserted into the upper detection column 5 to complete the connection. Then, the lifting air cylinder 2 operates, driving the detection frame 3 to descend, so that the connection part of the automotive air-conditioning pressing plate and the pipeline completely enters under the water surface. Then, the external detection air cylinder operates for detection (judging whether there is leakage through bubbles. The control direction of the air flow of the external detection air cylinder is: the air flow enters the part to be detected from the lower detection column 4, and returns to the external detection air cylinder from the upper detection column 5 after leaving the part). After the detection is completed, the lifting air cylinder 2 operates, driving the detection frame 3 to leave the water surface. The closing air cylinder 31 operates, separating the upper detection column 5 from the automotive air-conditioning pressing plate and the pipeline parts. Then, take out the automotive air-conditioning pressing plate and the pipeline parts that have completed the detection. Repeat the above operations to continuously detect the parts.
[0024] The spring 44 is in a compressed state, so that the lower closing piece 42 fits with the lower retaining ring 41 when not subject to other external forces, making the lower detection column 4 in a closed state.
[0025] When the pipeline is connected to the lower detection column 4, the pipeline first contacts the lower driven button 43, pushing the lower driven button 43 to rotate. The rotation of the lower driven button 43 drives the lower closing piece 42 to rotate. When the connection is completed, the end of the pipeline contacts the middle part of the lower driven button 43, the end of the lower driven button 43 contacts the lower closing piece 42, and the lower driven button 43 is in an inclined state. There is a gap between the pipeline and the lower closing piece 42 for the air flow to pass through.
[0026] When the upper closing plate 32 descends and the pipeline is connected to the upper detection column 5, the pipeline first contacts the upper driven button 53, pushing the upper driven button 53 to rotate. The rotation of the upper driven button 53 drives the upper closing piece 52 to rotate. When the connection is completed, the end of the pipeline contacts the middle part of the upper driven button 53, the end of the upper driven button 53 contacts the upper closing piece 52, and the upper driven button 53 is in an inclined state. There is a gap between the pipeline and the upper closing piece 52 for the air flow to pass through.
[0027] It should be noted that for the lower detection column 4 for installing the pipeline to be in a closed state, the upper detection column 5 is separated from the water surface, and the air flow direction of the external detection air cylinder is from the lower detection column 4 flowing out and from the upper detection column 5 flowing in. In this design, there is no need to specifically close the required upper detection column 5 and lower detection column 4. Any one can be used, and it is flexible, efficient and convenient.
[0028] As a specific embodiment of the improvement, a lower notch 61 is provided on the lower retaining ring 41, and part of the lower driven button 43 is embedded in the lower notch 61. An upper notch 62 is provided on the upper retaining ring 51, and part of the upper driven button 53 is embedded in the upper notch 62.
[0029] Through the above technical solution, the lower notch 61 is provided on the lower side surface of the lower retaining ring 41, and the upper notch 62 is provided on the upper side surface of the upper retaining ring 51. When the lower driven button 43 is embedded in the lower notch 61, the lower side surface of the lower retaining ring 41 is flat. When the upper driven button 53 is embedded in the upper notch 62, the upper side surface of the upper retaining ring 51 is flat. The lower closing piece 42 is attached to the lower retaining ring 41, and the upper closing piece 52 is attached to the upper retaining ring 51, so that the upper detection post 5 and the lower detection post 4 that are not connected to the parts can be sealed, making the detection result accurate.
[0030] As a specific embodiment of the improvement, a first notch 71 is provided on the lower closing piece 42, and part of the lower driven button 43 is embedded in the first notch 71. A second notch 72 is provided on the upper closing piece 52, and part of the upper driven button 53 is embedded in the second notch 72.
[0031] Through the above technical solution, the first notch 71 is provided at the upper end of the lower closing piece 42, and the second notch 72 is provided at the lower end of the upper closing piece 52. When the lower driven button 43 is embedded in the first notch 71, the edge of the upper end surface of the lower closing piece 42 is attached to the lower retaining ring 41. When the upper driven button 53 is embedded in the second notch 72, the lower end surface of the upper closing piece 52 is attached to the upper retaining ring 51, so that the upper detection post 5 and the lower detection post 4 that are not connected to the parts can be sealed, making the detection result accurate.
[0032] As a specific embodiment of the improvement, a lower rubber layer is provided on the upper side of the lower retaining ring 41, and the lower rubber layer abuts against the lower retaining ring 41. An upper rubber layer is provided on the lower side of the upper retaining ring 51, and the upper rubber layer abuts against the upper retaining ring 51.
[0033] Through the above technical solution, by providing the lower rubber layer and the upper rubber layer, the sealing effect of the upper detection post 5 and the lower detection post 4 that are not connected to the parts is good, improving the accuracy during the detection process.
[0034] The lower rubber layer abuts against the lower retaining ring 41, and the upper rubber layer abuts against the upper retaining ring 51, with a good sealing effect.
[0035] As a specific embodiment of the improvement, a plurality of through holes are provided on the upper and lower sides of the detection frame 3.
[0036] Through the above technical solution, a plurality of through holes are provided on the upper and lower sides of the detection frame 3, reducing the resistance when the detection frame 3 enters and exits the water, reducing the energy consumption during detection, and saving energy and reducing emissions.
[0037] As a specific embodiment of the improvement, a lower clamping block 81 is provided inside the lower detection column 4, and the lower clamping blocks 81 are distributed circumferentially. An upper clamping block 82 is provided inside the upper detection column 5, and the upper clamping blocks 82 are distributed circumferentially.
[0038] Through the above technical solution, the lower clamping block 81 is located below the lower closing piece 42 to limit its lowest position, and the upper clamping block 82 is located above the upper closing piece 52 to limit its highest position. When clamping the pipelines above and below the part, the lower driven button 43 and the upper driven button 53 are in an inclined state, the middle part abuts against the pipeline, and the end parts respectively abut against the lower closing piece 42 and the upper closing piece 52. There is a gap between the lower closing piece 42, the upper closing piece 52 and the end part of the pipeline.
[0039] The lower clamping block 81 and the upper clamping block 82 are limited, thereby improving the stability during use.

All technical solutions falling within the idea of the present invention belong to the protection scope of the present invention. It should be pointed out that for those of ordinary skill in the art, without departing from the principle of the present invention, several improvements and refinements should also be regarded as the protection scope of the present invention.
