[0002] The automotive brake hose assembly is an important component of the automotive braking system. Brake fluid flows inside it, and it can transmit the pressure of the brake fluid. In order to ensure its stable operation, the automotive brake hose assembly also has pressure holding capacity, resistance to aging in the external environment, and resistance to external high and low temperatures. The airtightness detection device used for the automotive brake hose assembly is a device to detect whether the automotive brake hose is leaking. Its main function is to ensure the airtightness of the automotive brake hose and avoid the danger caused by the pipeline leak.

[0003] However, existing airtight leak detection devices for automotive brake rigid pipe assemblies have the following problems when used:

[0004] Because the lengths of automotive brake hose assemblies vary, the device needs to be easily adjustable to facilitate testing of hoses of different lengths. However, existing airtight leak detection devices for automotive brake hose assemblies are not easily adjustable, making it difficult for the device to test brake hoses of different lengths and reducing the device's practicality.

[0005] To address the aforementioned issues, there is an urgent need for innovative designs based on existing airtight leak detection devices used in automotive brake rigid pipe assemblies. Utility Model Content

[0006] The purpose of this invention is to provide an airtight leak detection device for automotive brake rigid pipe assemblies, in order to solve the problem mentioned in the background art that the existing airtight leak detection devices for automotive brake rigid pipe assemblies are inconvenient to adjust, making it difficult for the device to detect brake rigid pipes of different lengths, thus reducing the practicality of the device.

[0007] To achieve the above objectives, this utility model provides the following technical solution: an airtight leak detection device for automotive brake rigid pipe assemblies, comprising a water tank and an air pump. The air pump is installed on the end face of the water tank, and a bracket is provided on the inner wall of the water tank. A sealing gasket is adhered to the end surface of the bracket, and a V-groove frame is fixedly installed on the upper surface of the bracket next to the sealing gasket. At the same time, a support frame is fixedly installed on the end of the upper surface of the bracket away from the sealing gasket. A limiting mechanism is installed on the upper inner wall of the support frame, and an adjusting sleeve is provided on the inner wall of the support frame below the limiting mechanism. A transmission sleeve is movably connected to the inner wall of the adjusting sleeve, and a sealing plate is fixedly installed on the end face of the transmission sleeve. A locking rod is fixedly connected to the lower surface of the end of the transmission sleeve. An air nozzle is fixedly installed on the inner wall of the sealing plate, and a sealing ring is adhered to the surface of the sealing plate next to the air nozzle.

[0008] Preferably, the bracket and the water tank are fitted together, and the end of the air nozzle is connected to the air pump via a hose.

[0009] Preferably, the limiting mechanism includes a knob and a toothed plate, with the knob threaded onto the inner wall of the support frame and the toothed plate movably disposed at the lower end of the knob.

[0010] Preferably, the knob and the support frame are threadedly connected, and the knob and the toothed plate are rotatably arranged, and the toothed plate and the support frame form a sliding structure.

[0011] Preferably, the outer wall of the adjusting sleeve below the toothed plate is fixedly provided with a toothed protrusion, and the toothed protrusion meshes with the toothed plate.

[0012] Preferably, the adjusting sleeve and the support frame form a rotating structure, and the adjusting sleeve and the transmission sleeve are threaded together, and the clamp and the bracket are slidably connected.

[0013] Compared with the prior art, the beneficial effects of this utility model are: the airtight leak detection device for automotive brake hard pipe assembly is easy to adjust, thereby facilitating the detection of brake hard pipes of different lengths, thus improving the practicality of the device;

[0014] First, place the automotive brake hose assembly to be tested on the V-groove bracket and move the hose so that one end of the hose is in contact with the sealing gasket. Then, by rotating the adjusting sleeve, the transmission sleeve moves, which in turn pushes the sealing plate to move, causing the sealing plate and sealing ring to fit tightly against the hose. At this point, the air nozzle is inserted into the hose, and the sealing gasket and sealing ring seal both ends of the hose. Then, by rotating the knob, the knob moves the toothed plate downward, and the toothed plate moves and engages with the toothed convex, thereby limiting the adjusting sleeve to ensure the stability of the sealing plate. At this point, the device completes the sealing of the hose. Next, the user fills the water tank with water, and then places the positioned hose bracket into the water tank. At this point, the water covers the hose on the bracket. Next, the air pump is started, and the air pump pumps air into the hose through the hose and air nozzle. At this point, the user observes whether air bubbles are generated in the water tank to determine whether there is an air leak and the location of the leak. Therefore, the device is easy to adjust, making it convenient to test brake hoses of different lengths, thus improving the practicality of the device. Attached Figure Description

[0020] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0021] Please see Figure 1-4 This utility model provides a technical solution: an airtight leak detection device for automotive brake rigid pipe assemblies, comprising a water tank 1, an air pump 2, a bracket 3, a sealing gasket 4, a V-groove bracket 5, a support frame 6, a limiting mechanism 7, a knob 701, a toothed plate 702, an adjusting sleeve 8, a toothed protrusion 9, a transmission sleeve 10, a sealing plate 11, an air nozzle 12, a sealing ring 13, a hose 14, and a locking rod 15. The air pump 2 is installed on the end face of the water tank 1, and the bracket 3 is provided on the inner wall of the water tank 1. A sealing gasket 4 is adhered to the end surface of the bracket 3, and the upper surface of the bracket 3 on the side of the sealing gasket 4 is fixed. A V-groove frame 5 is installed, and a support frame 6 is fixedly installed on the upper surface of the bracket 3 away from the sealing gasket 4. A limiting mechanism 7 is installed on the upper inner wall of the support frame 6, and an adjusting sleeve 8 is provided on the inner wall of the support frame 6 below the limiting mechanism 7. A transmission sleeve 10 is movably connected to the inner wall of the adjusting sleeve 8, and a sealing plate 11 is fixedly installed on the end face of the transmission sleeve 10. A locking rod 15 is fixedly connected to the lower surface of the end of the transmission sleeve 10. An air nozzle 12 is fixedly installed on the inner wall of the sealing plate 11, and a sealing ring 13 is adhered to the surface of the sealing plate 11 on the side of the air nozzle 12.

[0022] The bracket 3 and the water tank 1 are fitted together, and the end of the air nozzle 12 is connected to the air pump 2 through the hose 14, which makes it convenient for the user to put the bracket 3 into the water tank 1 or take the bracket 3 out of the water tank 1, and also makes it convenient for the air pump 2 to pump gas into the pipeline to be tested through the hose 14 and the air nozzle 12.

[0023] The limiting mechanism 7 includes a knob 701 and a toothed plate 702. The knob 701 is threaded onto the inner wall of the support frame 6, and the lower end of the knob 701 is movably provided with the toothed plate 702, which facilitates the limiting adjustment sleeve 8 through the limiting mechanism 7, thereby ensuring the stability of the sealing plate 11.

[0024] The knob 701 is threadedly connected to the support frame 6, and the knob 701 and the toothed plate 702 are rotatably set. The toothed plate 702 and the support frame 6 form a sliding structure, which makes it easy for the user to rotate the knob 701 so that the knob 701 moves downward relative to the support frame 6. At this time, the knob 701 drives the toothed plate 702 to move downward stably relative to the support frame 6.

[0025] The outer wall of the adjusting sleeve 8 below the toothed plate 702 is fixedly provided with a toothed protrusion 9, and the toothed protrusion 9 and the toothed plate 702 mesh with each other, so as to facilitate the movement of the toothed plate 702 and the meshing with the toothed protrusion 9, thereby limiting the adjusting sleeve 8.

[0026] The adjusting sleeve 8 and the support frame 6 form a rotating structure, and the adjusting sleeve 8 and the transmission sleeve 10 are threaded together. The locking rod 15 and the bracket 3 are slidably connected, which makes it easy for the user to rotate the adjusting sleeve 8, so that the adjusting sleeve 8 drives the transmission sleeve 10 to move. As the transmission sleeve 10 moves, the transmission sleeve 10 drives the locking rod 15 to slide relative to the bracket 3, thereby making the adjusting sleeve 8 drive the sealing plate 11 to move stably.

[0027] Working principle: When using this airtight leak detection device for automotive brake rigid pipe assemblies, firstly as follows... Figure 1-4 As shown, the user places the automotive brake rigid hose assembly to be tested on the V-groove bracket 5. The user then moves the hose so that one end of the hose is in contact with the sealing gasket 4. Next, the user rotates the adjusting sleeve 8, which in turn moves the transmission sleeve 10. Simultaneously, the transmission sleeve 10 causes the locking rod 15 to slide relative to the bracket 3. Then, the transmission sleeve 10 pushes the sealing plate 11 to move, which in turn moves the sealing ring 13 so that it is tightly against the hose. At this point, the air nozzle 12 is inserted into the hose, and the sealing gasket 4 and sealing ring 13 seal both ends of the hose. The user then rotates the knob 701, which moves downward relative to the support frame 6. Finally, the user rotates the knob 701... The toothed plate 702 moves downward relative to the support frame 6, and then the toothed plate 702 moves to engage with the toothed protrusion 9, thereby limiting the adjustment sleeve 8 to ensure the stability of the sealing plate 11. At this time, the device completes the sealing of the pipeline. Then, the user injects water into the water tank 1, and then the user puts the positioned pipeline bracket 3 into the water tank 1. At this time, the water covers the pipeline on the bracket 3. Next, the user starts the air pump 2, and then the air pump 2 pumps air into the pipeline through the hose 14 and the air nozzle 12. At this time, the user observes whether there are air bubbles in the water tank 1, so as to determine whether there is an air leak and the location of the leak. Therefore, the device is easy to adjust, which makes it convenient for the device to test brake hard pipes of different lengths, thus improving the practicality of the device.
