[0002] A car is a vehicle that is powered by a motor vehicle and has four or more wheels and is not track-borne. It is primarily used to carry people and / or goods, or to tow vehicles carrying people and / or goods. During the use of a car, air leakage in the rear axle brake line is a common problem in the vehicle's braking system, potentially leading to brake failure or performance degradation, thus endangering driving safety.
[0003] When encountering a rear axle brake line leak, a leak detection device is needed to detect it, so as to facilitate the repair and replacement of the line. However, the newly removed line may be attached with debris, affecting the accuracy of the detection, and the line cannot be fully sensed, causing the user to waste time and reduce the detection efficiency. Therefore, we propose a rear axle brake line leak detection device. Utility Model Content

[0006] As a further solution of the present invention: one end of the water inlet pipe is fixedly connected to the inner rear side of the detection chamber, and the other end of the water inlet pipe is fixedly connected to the water inlet end of the water pump. The water pump is fixedly connected to the top left side of the base and is located between the detection chamber and the cleaning chamber.
[0007] As a further solution of the present invention: the water outlet end of the water pump is fixedly connected to one end of the water outlet pipe, and the other end of the water outlet pipe is fixedly connected to a flushing port, and the flushing port is located in the middle of the top side of the cleaning bin.
[0008] As a further solution of the present invention: the height of the connecting rod is greater than the height of the detection chamber, a U-shaped groove is opened in the middle of the front side of the cleaning chamber, and the flushing port and the U-shaped groove are correspondingly arranged.

After the pipe is inflated, the electric push rods on both sides are started to drive the connecting rod and the fixing plate to descend and enter the detection chamber. If the pipe leaks, a large number of bubbles will be generated in the water inside the detection chamber.

[0021] In addition, the technical features involved in the various embodiments of the present invention described below can be combined with each other as long as they do not conflict with each other.
[0022] Please see the attached Figure 1 -Attached Figure 3 The utility model relates to a leakage detection device for a rear axle brake line, comprising a base 1, the left and right ends of the top front side of the base 1 are fixedly connected to the bottom end of an electric push rod 2, the driving end of the electric push rod 2 is fixedly connected to a connecting rod 3, the connecting rod 3 is L-shaped, and the bottom end of the connecting rod 3 is fixedly connected to a fixing plate 4. An empty slot 5 is opened on the adjacent side of the two fixing plates 4, a fixed connecting port 6 is provided inside the left empty slot 5, and an air intake connecting port 7 is provided inside the right empty slot 5. One side of the air intake connecting port 7 is fixedly connected to one end of an air intake pipe 8, and the other end of the air intake pipe 8 is fixedly connected to the driving end of an inflator. The outside of the inflator is fixedly connected to an inflator case 9, and the bottom side of the inflator case 9 is fixedly connected to the top side wall of the base 1. A cleaning bin 15 is provided on the left side of the inflator case 9, and a detection bin 10 is provided between the two electric push rods 2. The detection bin 10 and the cleaning bin 15 are respectively fixedly connected to the front and back sides of the top of the base 1.
[0023] Specifically, through the coordinated setting of the fixed connection port 6 and the air intake connection port 7, the two ends of the brake pipeline are respectively connected and fixed thereto, and then the inflator in the inflation box 9 is started to inflate the pipeline through the air intake pipe 8. After filling, the connecting rod 3 and the fixed plate 4 are driven down by starting the electric push rods 2 on both sides and enter the detection chamber 10. If the pipeline leaks, a large number of bubbles will be generated in the water inside the detection chamber 10. If there is no leakage, a large number of bubbles will not be generated.
[0024] In the first embodiment, one end of a water inlet pipe 11 is fixedly connected to the inner rear side of the detection chamber 10, and the other end of the water inlet pipe 11 is fixedly connected to the water inlet end of a water pump 12. The water pump 12 is fixedly connected to the left side of the top of the base 1 and is located between the detection chamber 10 and the cleaning chamber 15. The water outlet end of the water pump 12 is fixedly connected to one end of a water outlet pipe 13, and the other end of the water outlet pipe 13 is fixedly connected to a flushing port 14. The flushing port 14 is located in the middle of the top side of the cleaning chamber 15;
[0025] Specifically, by starting the water pump 12, the water source inside the detection chamber 10 is pumped out through the water inlet pipe 11, and transported to the flushing port 14 through the water outlet pipe 13. Then, the surface of the pipeline is cleaned through the flushing port 14 to prevent foreign matter from adhering to it and affecting the detection.
[0026] In the second embodiment, a baffle 17 is fixedly connected between the two fixing plates 4. The baffle 17 is located below the air inlet connection port 7 and the fixed connection port 6. A gap is provided between the front and rear sides of the baffle 17 and the inner wall of the detection chamber 10.
[0027] Specifically, by setting the baffle 17, the pipeline is placed to facilitate up and down movement. By setting the gap, when the baffle 17 is lowered, the water inside the detection chamber 10 can submerge the pipeline, thereby performing detection.
[0028] Working principle:
[0029] First, by starting the water pump 12, the water source inside the detection chamber 10 is pumped out through the water inlet pipe 11, and transported to the flushing port 14 through the water outlet pipe 13, and then the surface of the pipeline is cleaned through the flushing port 14 to prevent foreign matter from adhering to it, thereby affecting the detection; after completion, the two ends of the brake pipeline are respectively connected and fixed to it through the coordinated setting of the fixed connection port 6 and the air intake connection port 7, and then the inflator in the inflation box 9 is started to inflate the pipeline through the air intake pipe 8. After filling, the electric push rods 2 on both sides are started to drive the connecting rod 3 and the fixing plate 4 to descend and enter the detection chamber 10. If the pipeline leaks, a large number of bubbles will be generated in the water inside the detection chamber 10. If there is no leak, a large number of bubbles will not be generated, thereby achieving the effect of comprehensive sensing of the pipeline and improving the user's detection efficiency; when installing the pipeline, the distance between the fixed connection port 6 and the air intake connection port 7 can be changed by setting the empty slot 5, which is convenient for adjustment. At this point, the entire workflow is completed.
