[0002] At present, although the drain pipe in the car is a simple component, it plays an important role in protecting the vehicle and improving driving comfort. The functions of the drain pipe in the car are slightly different according to the location and environment where it is installed, but generally it is used to drain the moisture accumulated in the car, such as rainwater, water entering when washing the car, etc.; prevent water accumulation in the car to avoid rust and damage to electronic components; keep the car dry to prevent mold and odor; installed in the air conditioning system to drain condensed water.
[0003] At present, there are existing technologies for testing the air tightness of drain pipes with simple straight pipe structures, such as the Chinese patent application "A skylight drain pipe air tightness testing device", publication number: CN220854038U; discloses a water tank containing liquid, in which a first mounting seat and a second mounting seat are installed, the first mounting seat is provided with a notch for accommodating the first end of the drain pipe, and a compression piece is provided to seal the drain pipe extending into the notch, a connector is provided on one side of the second mounting seat, one end of the connector is connected to the pneumatic system and the air pressure detection alarm device, and the other end of the connector is connected to the second end of the drain pipe, and the drain pipe to be tested is completely immersed in the liquid; the pneumatic system works to inflate the drain pipe, and the air pressure detection alarm device works to detect the air pressure change in the drain pipe after inflation. The drain pipe to be tested is inflated and pressure maintained, and the air pressure detection alarm device is connected. When the air pressure in the drain pipe drops significantly, an alarm is issued to indicate that the test result is unqualified.
[0004] However, there is no universal testing equipment on the market for the working condition testing of drainage pipes with irregular structures and large floor space. All the testing equipment is designed specifically for the drainage pipe structure of a certain vehicle model, and the testing equipment is relatively large and complex. Moreover, due to the diversity of vehicle models involved, the dedicated testing equipment for one vehicle and one tooling also has high requirements for the testing cost and testing site of the testing party. In view of this, a simple drainage pipe test bracket device is needed that can be repeatedly used on different vehicle models to overcome the defects of the previous technology. Summary of the invention
[0005] The technical problem to be solved by the present application is to provide a drain pipe inspection tool to simulate the drain pipe working in a vehicle body and test whether the drain pipe meets the standards. The experimental bracket has a high utilization rate and inspection efficiency.
[0006] The technical solution adopted in the present application is: a detection tool for a drain pipe, comprising a base, a telescopic support rod and an installation simulation frame, the base is regularly provided with a plurality of installation holes, the telescopic support rod is detachably installed to the installation holes, an environmental simulation block is detachably installed on the top or the outer peripheral surface of the telescopic support rod, a plurality of environmental simulation blocks constitute an installation simulation frame for the drain pipe, and the drain pipe to be inspected is installed on the installation simulation frame; a docking simulation block is installed on the environmental simulation block located at a high position in the installation simulation frame, and the docking simulation block is used to inject detection liquid and connect with the water inlet of the drain pipe.

Secondly, the present application realizes the installation simulation of the in-vehicle environment of the drain pipe through a plurality of telescopic support rods and a plurality of environmental simulation blocks, and its detection cost is lower and the assembly is relatively simpler. And a docking simulation block is installed on the environmental simulation block located at a high position in the installation simulation frame, and the docking simulation block simulates the parts in the car that are docked with the water inlet of the drain pipe, but it is not necessary to simulate the entire docking parts, and only the local structure of the connection between the parts and the drain pipe needs to be simulated. The docking simulation block is connected to the water inlet of the drain pipe. The detection of the reliability and stability of docking at the water inlet of the drain pipe is realized. Injecting the test liquid into the docking simulation block further tests the performance of the drain pipe to see if there is a possibility of leakage during its operation and whether the drain pipe meets the standards. Finally, the present application provides multiple mounting holes, and the telescopic support rod can be installed in different mounting holes according to the actual needs of the drain pipe. Furthermore, the setting of the telescopic support rod also enables the height of the environmental simulation block to be adjustable.
[0008] At this point, the positions and heights of the multiple environmental simulation blocks that constitute the installation simulation frame for installing the drain pipe are adjustable, and the environmental simulation block itself and the telescopic support rod are also detachably connected, so environmental simulation blocks of different structures can be replaced according to the actual installation requirements of the drain pipe.
