[0002] Car air conditioning pipeline tightness test is a key step to ensure the normal operation of the car air conditioning system. This test process mainly checks whether there are leaks in the pipelines in the air conditioning system to ensure that the refrigerant (such as Freon) will not overflow from the system, thus affecting the cooling effect of the air conditioner.

[0003] In the existing patent application with application number CN202320757686.3, a quick interface for air tightness detection of automobile air-conditioning pipelines is proposed. When sealing one end of the automobile air-conditioning pipeline, this structure needs to first rotate the bidirectional screw to drive the two second sliders to move, and then drive the two clamping seats to clamp the air-conditioning pipeline, and then the screw needs to be driven by the crank to rotate, so as to push the plug to seal one end of the air-conditioning pipeline. This process is relatively cumbersome and troublesome, which will reduce the efficiency of sealing the air-conditioning pipeline, and then reduce the efficiency of air tightness detection of automobile air-conditioning pipelines, so it needs to be improved. Utility Model Content

There are two fixing plates and they are respectively mounted on the two ends of the mounting guide rod. A blocking spring is sleeved on the mounting guide rod. A movable working table is slidably mounted on the two mounting guide rods on the two mounting rails. The blocking structure is fixedly mounted on the upper end of the movable working table.

[0007] Preferably, a movable bracket is fixedly mounted on the lower end of the work desk.

[0008] Preferably, the blocking structure consists of a support rod and a blocking head, the support rod is fixedly mounted on the upper end of the work table, the blocking head is fixedly mounted on the front end of the support rod, and the blocking structure is located between two mounting rails.

[0013] By setting up installation rails, sealing springs and a mobile workbench, and fixing the clamping structure to the upper end of the mobile workbench at the same time, before using the clamping structure to clamp and fix the automobile air-conditioning duct, it is necessary to first pull the mobile workbench forward. When there is a certain distance between the clamping structure and the sealing structure, the clamping structure is used to clamp and fix the automobile air-conditioning duct, and then the mobile workbench can be released.

DETAILED DESCRIPTION

[0019] In order to make the technical means, creative features, objectives and effects achieved by the present invention easy to understand, the present invention is further described below in conjunction with specific implementation methods.

[0020] See also Figure 1 , Figure 2 , Figure 3 , Figure 4 As shown, a vehicle air-conditioning pipeline sealing detection device includes a working table 1, a clamping structure 2 and a blocking structure 3. A movable bracket 7 is fixedly installed at the lower end of the working table 1. The blocking structure 3 consists of a support rod 11 and a blocking head 12. The support rod 11 is fixedly installed at the upper end of the working table 1. The blocking head 12 is fixedly installed at the front end of the support rod 11. The blocking structure 3 is located between two mounting guide rails 4. The clamping structure 2 consists of a mounting plate 8, a threaded rod 9 and a clamping assembly 10. There are two mounting plates 8 and they are symmetrically fixedly installed at the upper end of the mobile working table 6. The threaded rod 9 is rotatably installed on the two mounting plates 8. There are two clamping assemblies 10 and they are symmetrically installed on the threaded rod 9. The clamping structure 2 is located at the front side of the blocking structure 3.

[0021] See also Figure 1 , Figure 2 , Figure 3 , Figure 4As shown, two mounting guide rails 4 are symmetrically fixedly installed on the upper end of the work desktop 1, and the mounting guide rail 4 is composed of a fixing plate 13 and a mounting guide rod 14. There are two fixing plates 13 and they are respectively installed at the two ends of the mounting guide rod 14. A blocking spring 5 is sleeved on the mounting guide rod 14. A movable workbench 6 is slidably installed on the two mounting guide rods 14 on the two mounting guide rails 4. The blocking structure 3 is fixedly installed on the upper end of the movable workbench 6. The fixing plate 13 on the mounting guide rail 4 is fixedly installed on the upper end of the work desktop 1. The blocking spring 5 is located on the front side of the movable workbench 6. Two mounting through holes 15 are symmetrically opened on the movable workbench 6. The mounting through holes 15 penetrate the movable workbench 6 from front to back. The movable workbench 6 is slidably installed on the two mounting guide rods 14 on the two mounting rails 4 through the two mounting through holes 15 opened thereon. A handle groove 16 is provided, and the handle groove 16 passes through the movable workbench 6 up and down. By setting the mounting guide rail 4, the sealing spring 5 and the movable workbench 6, the clamping structure 2 is installed and fixed to the upper end of the movable workbench 6 at the same time. Before using the clamping structure 2 to clamp and fix the automobile air-conditioning duct, it is necessary to pull the movable workbench 6 forward first. When there is a certain distance between the clamping structure 2 and the sealing structure 3, the clamping structure 2 is used to clamp and fix the automobile air-conditioning duct, and then the movable workbench 6 can be released.

[0022] It should be noted that the utility model is a vehicle air conditioning pipeline airtightness detection device. During the detection, one end of the vehicle air conditioning pipeline needs to be blocked. The method is to first pull the mobile workbench 6 forward so that the mobile workbench 6 slides forward on the mounting guide rod 14 on the mounting guide rail 4. At this time, the blocking spring 5 will be compressed. When the clamping structure 2 at the upper end of the mobile workbench 6 and the blocking structure 3 have a certain distance, the clamping structure 2 is used to clamp and fix the vehicle air conditioning pipeline. At this time, it is only necessary to put the vehicle air conditioning pipeline between the two clamping components 10. The threaded rod 9 is then rotated, and finally the two clamping assemblies 10 clamp the automobile air-conditioning duct, and then the movable workbench 6 can be loosened. At this time, under the elastic force of the blocking spring 5, the movable workbench 6 will slide backward on the installation guide rod 14, and the automobile air-conditioning duct clamped by the clamping structure 2 will also move backward, so that the blocking head 12 on the blocking structure 3 will be passively plugged into the automobile air-conditioning duct. At this time, the blocking of the automobile air-conditioning duct is completed, and then the relevant equipment can be used to perform airtightness detection on the automobile air-conditioning duct.
