AI Technical Summary
When the existing handbrake relay valve bracket is in use, the protective structure installed on the surface can only protect the surface of the relay valve. The connection between the pipe connected to the relay valve surface and the relay valve is easily worn by airflow impact and vehicle vibration, affecting the sealing performance and service life. It may also cause the connection to loosen, resulting in air pressure leakage in the braking system and affecting vehicle stability.
The system employs a combination structure consisting of a protective cover, a fixed cover, a side plate, a slide groove, a slider, an adjusting bracket, a second bolt, a rubber sleeve, a first connecting tongue, a threaded pipe, and a second connecting tongue. By clamping and fixing the relay valve at the connection point with the pipeline, and in conjunction with the support body, adjusting ring, crossbar, and third bolt, the angle of the relay valve can be adjusted to prevent loosening and wear.
This effectively prevents loosening and wear at the connection between the relay valve and the pipeline, ensuring the sealing and stability of the braking system, extending the service life of the pipeline, reducing the risk of gas leakage, and improving the driving stability of the vehicle.

Technical Field
[0001] This utility model belongs to the technical field of handbrake relay valves, specifically relating to a shockproof and noise-reducing handbrake relay valve bracket. Background Technology
[0002] A handbrake relay valve bracket is a device used to secure the handbrake relay valve. Typically made of metal, it has a specific shape and structure to connect to the vehicle frame or other components. Its primary function is to provide a stable mounting position for the handbrake relay valve, ensuring that it does not shift or wobble due to vibrations or bumps during vehicle operation, thus guaranteeing its normal operation. Simultaneously, the bracket, through its optimized design and installation angle, allows for smoother connections between the relay valve and related components such as the brake lines, facilitating the normal flow and pressure transmission of compressed air in the braking system. This, in turn, improves the reliability and stability of the entire braking system, ensuring vehicle safety.
[0003] The "A High-Speed Railway Relay Valve Support with Protective Structure" disclosed in application number "CN202420967654.0" is also an increasingly mature technology. The fixing frame of the high-speed railway relay valve support with protective structure forms an elastic damping structure with the support through the damping spring, and the relay valve forms a spiral locking structure with the support through the screw and nut. Thus, the damping spring reduces the vibration between the support and the relay valve, thereby avoiding the impact of external vibrations on the relay valve. Through the cooperation of the damping spring and the damper, the vibration can be effectively attenuated, avoiding the impact of external vibrations on the relay valve, and at the same time, it can also play a certain role in noise reduction.
[0004] The existing handbrake relay valve bracket only protects the surface of the relay valve when in use. However, the pipes connected to the relay valve are subject to airflow impact and vehicle vibration over a long period of time, which can easily cause wear and affect the sealing performance and service life. Furthermore, the vibration of the vehicle during driving may cause the connection between the relay valve and the pipes on its surface to loosen. Loosening of the connection will lead to air pressure leakage in the brake line, prolonging the time for the brake system to build up pressure, and thus affecting the vehicle's stability.

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.
[0024] Please see Figures 1-5 This utility model provides the following technical solution: a shock-absorbing and noise-reducing handbrake relay valve bracket, comprising a bracket body 1, a shock-absorbing spring 2 provided on the top surface of the bracket body 1, a fixing frame 3 connected to the top of the shock-absorbing spring 2, a relay valve 4 placed on the top of the fixing frame 3, and a screw at the bottom of the relay valve 4 passing through the fixing frame 3 and threadedly connected to a nut 5, the top of the nut 5 abutting against the bottom of the bracket body 1, a connecting lug 6 provided on the top surface of the bracket body 1, a protective cover 8 threadedly connected to the surface of the connecting lug 6 by a first bolt 7, a fixing cover 9 connected to the top surface of the opening end of the protective cover 8, and a fixing cover 9 connected to the bottom opening end of the fixing cover 9. Side plate 10, with a sliding groove 11 at the bottom of side plate 10 to connect slider 12. The bottom surface of slider 12 is connected to the top of adjustment bracket 13. The bottom of slider 12 is threaded to the bottom of side plate 10 by second bolt 14. Rubber sleeve 15 is bonded to the inner wall of adjustment bracket 13. One side of rubber sleeve 15 is fitted onto first connecting tongue 16. The surface of first connecting tongue 16 near rubber sleeve 15 is connected to the surface of adjustment bracket 13. The surface of first connecting tongue 16 is threaded to the inner wall of threaded tube 17. The inner wall of threaded tube 17 is threaded to second connecting tongue 18. The other side of second connecting tongue 18 is connected to the opening end of fixed cover 9.
[0025] Preferably, circular through grooves are provided at the intersection of the surface of the protective cover 8 and the connection port of the relay valve 4.
[0026] In practical use, a through groove of appropriate size is opened at the intersection of the protective cover 8 and the inlet and outlet ends of the relay valve 4. At the same time, a fixed cover 9 is connected to the top of the through groove, so as to facilitate the reinforcement and support of the relay valve 4 and the pipe connection above it by using the cooperation of the fixed cover 9 and the adjusting support 13.
[0027] Preferably, the upper end of the slider 12 is an "L"-shaped protrusion, and the shape and size of the protrusion are adapted to the slide groove 11. The fixed cover 9, side plate 10, slide groove 11, slider 12, adjusting support 13 and second bolt 14 form a threaded connection structure.
[0028] In practical use, unscrew the second bolt 14 threaded between the slider 12 and the side plate 10, pull the adjusting bracket 13 outward, so that the slider 12 connected to it slides outward in the groove 11 starting from the bottom of the side plate 10 until it slides to one end of the groove 11. Then, press the bottom of the pipe against the rubber sleeve 15 on the inner wall of the adjusting bracket 13. Repeat the above operation to push the adjusting bracket 13 towards the end closer to the protective cover 8. After the slider 12 on the adjusting bracket 13 moves to the other end of the groove 11, use the fixing structure on one side of the pipe to connect it to the relay valve 4. Then, use the second bolt 14 to thread the connection between the slider 12 and the side plate 10, and fix the connection between the fixing cover 9 and the adjusting bracket 13, thereby clamping and fixing the pipe to prevent it from loosening.
[0029] Preferably, an arc-shaped through groove is provided on one side of the rubber sleeve 15, and the shape and size of the through groove are adapted to the first connecting tongue 16.
[0030] In practical use, the through groove on one side of the rubber sleeve 15 is used to fit it onto the surface of the first connecting tongue 16, and then it abuts against the inner wall of the adjusting bracket 13 and adheres to the inner wall of the adjusting bracket 13, thereby providing buffer protection for the contact area between the pipe and the adjusting bracket 13.
[0031] Preferably, an adjusting ring 19 is connected to the bottom surface of the bracket body 1, and a crossbar 20 is slidably connected to the surface of the adjusting ring 19. A third bolt 21 is used to penetrate the inner wall of the ring of the base frame 22 on one side of the crossbar 20 and is threaded to the surface of the crossbar 20.
[0032] In practical use, the third bolt 21, which is threadedly connected to the inner wall of the crossbar 20 and the base frame 22, is unscrewed. This allows the angle of the relay valve 4 to be adjusted according to the orientation of each pipe, thereby selecting the most suitable angle to meet the orientation of each pipe as much as possible and avoid bending of the pipes during connection. After adjustment, the third bolt 21 is passed through the threaded groove at the corresponding position on the inner wall of the base frame 22 and connected to the crossbar 20, thereby fixing the position of the relay valve 4 with the adjusted angle.
[0033] Preferably, the first connecting tongue 16, the threaded tube 17, and the second connecting tongue 18 form a threaded connection structure.
[0034] In practical use, the threaded tube 17 is sleeved on the surface of the first connecting tongue 16 and the second connecting tongue 18, so that the first connecting tongue 16 and the second connecting tongue 18 are tightened when the thread on the inner wall of the threaded tube 17 rotates, thereby clamping and fixing the pipe between the two.
[0035] Preferably, the base frame 22 has a ring of equally spaced threaded grooves distributed on its annular structure surface, and the shape and size of the threaded grooves are adapted to the third bolt 21.
[0036] In practical use, the angle of the relay valve 4 is adjusted by rotating the crossbar 20 connected to the inner wall of the base frame 22 on the adjusting ring 19. After the adjustment is completed, the third bolt 21 is threaded onto the crossbar 20 after passing through the threaded groove at the corresponding position on the inner wall of the ring of the base frame 22, thereby fixing the position of the relay valve 4 whose angle has been adjusted.
[0037] Working principle: When installing and fixing the relay valve 4 using the bracket body 1, firstly, the screw at the bottom of the relay valve 4 is passed through the through groove on the surface of the fixing frame 3. Then, the relay valve 4 is placed on the fixing frame 3. At the same time, after the screw at the bottom of the relay valve 4 passes through the bracket body 1, the nut 5 is used to thread and fix the position of the relay valve 4 on the bracket body 1. Thus, the damping spring 2 at the bottom of the fixing frame 3 and the dampers at its upper and lower ends respectively form an elastic damping structure with the bracket body 1. The relay valve 4, through its bottom screw 4 and nut 5, forms a spiral locking structure with the bracket body 1. Thus, the elastically expandable fixing frame 3 avoids external vibrations from affecting the operation of the relay valve 4, thereby reducing the noise caused by the collision between the bottom of the relay valve 4 and the bracket body 1 during use. At this time, the connecting lug 6 connected to the top of the bracket body 1 and the first bolt 7 are threaded together to make the protective cover 8 The relay valve 4 is fixed to the surface of the protective cover 8 for protection. A through groove of appropriate size is opened at the intersection of the protective cover 8 and the inlet and outlet ends of the relay valve 4. The top of the through groove is connected to a fixing cover 9. The mounting holes and fixing components on the horizontal plates on both sides of the base frame 22 are used to fix the position of the base frame 22 on the vehicle, thereby fixing the position of the relay valve 4 on the vehicle surface. At this time, according to the orientation of each pipe on the vehicle that needs to be connected to the relay valve 4, the third bolt 21 threaded to the crossbar 20 and the inner wall of the ring of the base frame 22 is unscrewed. The angle of the relay valve 4 is adjusted according to the orientation of each pipe to select the most suitable angle and try to meet the orientation of each pipe to avoid bending of the pipe during connection. After the adjustment is completed, the third bolt 21 is passed through the threaded groove at the corresponding position opened on the inner wall of the ring of the base frame 22 and connected to the crossbar 20 to fix the position of the relay valve 4 with the adjusted angle.
[0038] At this point, hold the pipe that needs to be fixed with one hand, first unscrew the threaded pipe 17 connected between the first connecting tongue 16 and the second connecting tongue 18, and then unscrew the second bolt 14 connected between the slider 12 and the side plate 10. Pull the adjusting bracket 13 outward so that the slider 12 connected to it slides outward in the groove 11 starting from the bottom of the side plate 10 until it slides to one end of the groove 11. Then, press the bottom of the pipe against the rubber sleeve 15 on the inner wall of the adjusting bracket 13. Repeat the above operation to push the adjusting bracket 13 towards the end closer to the protective cover 8. After the slider 12 on the adjusting bracket 13 moves to the other end of the groove 11, use the fixing structure on one side of the pipe to connect it to the relay valve 4, and then use the second bolt 14 to connect it to the relay valve 4. The bolt 14 connects the slider 12 and the side plate 10 via a threaded connection, and fixes the connection between the fixing cover 9 and the adjusting bracket 13, thereby clamping and fixing the pipe to prevent it from loosening. Then, the threaded tube 17 is sleeved on the surface of the first connecting tongue 16 and the second connecting tongue 18, and the threads are tightened at the intersection of the first connecting tongue 16, the second connecting tongue 18 and the pipe, thereby clamping and fixing the pipe on the fixing cover 9 and the adjusting bracket 13. At this time, the rubber pads and rubber sleeves 15 provided on the inner walls of the fixing cover 9 and the adjusting bracket 13 provide protection at the intersection with the pipe, thereby preventing wear on the contact surface between the pipe and the fixing cover 9 and the adjusting bracket 13 during vibration, thus ensuring the connection of the relay valve 4 and each pipe, and preventing the connection from loosening and affecting the stability of the vehicle.
[0039] Finally, it should be noted that the above are merely preferred embodiments of this utility model and are not intended to limit the utility model. Although the utility model has been described in detail with reference to the foregoing embodiments, those skilled in the art can still modify the technical solutions described in the foregoing embodiments or make equivalent substitutions for some of the technical features.
