Description

Technical Field

[0001] This utility model relates to the field of hoses, and in particular to a low-temperature resistant braking hose. Background Technology

[0002] The working principle of a car brake hose is to transmit brake fluid in the car's braking system. Its two ends are connected to the brake calipers and the master cylinder. When the driver presses the brake pedal, the booster applies pressure to the master cylinder, pushing the brake fluid in the master cylinder through the brake hose to the brake calipers of each wheel, so that the brake calipers on the brake calipers clamp the brake discs to achieve the purpose of deceleration or stopping.

[0003] Existing brake hoses are all removable installations. Apart from the ends of the hoses connecting to relevant automotive components, the main body of the hose mostly hangs down naturally. When the car is moving around or turning, the brake hoses are prone to swaying due to inertia. Prolonged swaying can cause the connection between the brake hose and the automotive components to loosen, resulting in brake fluid leakage and affecting the car's braking performance. Utility Model Content

[0004] This application provides a low-temperature resistant brake hose, which reduces the swaying of the hose during vehicle operation by connecting the hose body to the vehicle's control arm, thereby reducing the probability of leakage at the connection points between the hose body and various components.

[0005] The low-temperature resistant brake hose provided in this application adopts the following technical solution: A low-temperature resistant brake hose includes a hose body, a metal tube, and a mounting block. The metal tube is sleeved on the hose body. The mounting block has a mating hole through which the hose body and the metal tube pass. Multiple clamping blocks are slidably disposed within the mating hole, and the multiple clamping blocks are located around the metal tube. The mounting block also has a driving part for driving the multiple clamping blocks to move toward the metal tube so that the multiple clamping blocks clamp the metal tube. The mounting block also has a connecting part for connecting to the swing arm of a vehicle.

[0006] By adopting the above technical solution, the connecting part fixes the mounting block to the swing arm of the car, and the clamping block clamps the metal tube so that the tube body is fixed to the swing arm of the car along with the mounting block, thereby reducing the shaking of the tube body during the car's operation and reducing the probability of leakage at the connection between the tube body and various components.

[0007] Preferably, the connecting part is a hoop, the mounting block has a through groove, the through groove passes through the mounting block, and the hoop passes through the through groove and clamps the mounting block onto the swing arm of the vehicle.

[0008] By adopting the above technical solution, the mounting block can be easily and conveniently fixed onto the car's swing arm.

[0009] Preferably, the driving part includes a rotating tube, a first conical surface on the inner wall of the rotating tube, and a second conical surface on the clamping block. The wall of the mating hole is provided with threads, and the rotating tube is threadedly connected to the mating hole. The first conical surface and the second conical surface abut against each other. When the rotating tube is rotated to screw into the mating hole, the first conical surface presses against the second conical surface, driving multiple clamping plates to move toward the metal tube and clamp the metal tube.

[0010] By adopting the above technical solution, when fixing the pipe body to the mounting block, the pipe body is first passed through multiple clamping blocks, and then the rotating tube is rotated to enter the mating hole. This causes the rotating tube to drive the multiple clamping blocks to move closer to each other and clamp the pipe body, thus completing the connection between the pipe body and the mounting block. The clamping force of the clamping blocks on the pipe body can be controlled by controlling the distance the rotating tube rotates into the mating hole.

[0011] Preferably, springs are provided at both ends of the metal tube, and both springs are sleeved on the tube body.

[0012] By adopting the above technical solution, a spring is set to protect the tube body, preventing it from twisting during vehicle operation, and also reducing the shaking of the tube body to a certain extent.

[0013] Preferably, the wall of the mating hole is provided with multiple sliding grooves, and the side of the clamping block facing away from the tube body is provided with a sliding rod, which is slidably connected in the sliding groove along the axis perpendicular to the mating hole.

[0014] By adopting the above technical solution, the sliding of the clamping block is achieved.

[0015] Preferably, the clamping block has a threaded hole on the side facing away from the tube body, one end of the slide rod is slidably connected in the slide groove, and the other end of the slide rod is threadedly connected in the threaded hole.

[0016] By adopting the above technical solution, the assembly of the clamping block and the slide bar is facilitated.

[0017] Preferably, the clamping block consists of two pieces, and the number of the sliding grooves is two, with the two sliding grooves facing each other, and one of the sliding grooves penetrating through the mounting block.

[0018] By adopting the above technical solution, the clamping effect of the clamping block is improved.

[0019] The main technical effects of this utility model are reflected in the following aspects: 1. This utility model fixes the pipe body to the swing arm of the car, reduces the shaking of the pipe body during the car's movement, and reduces the probability of leakage at the connection between the pipe body and various components. 2. This utility model can control whether the clamping block clamps the tube body by controlling the distance the rotating tube enters the mating hole; 3. This utility model incorporates a spring to protect the tube body and prevent it from twisting during vehicle operation. Attached Figure Description

[0025] The present application will be further described in detail below with reference to the accompanying drawings, so that the technical solution of the present application can be more easily understood and mastered.

[0026] Reference Figure 1 and Figure 2 This embodiment of a low-temperature resistant brake hose includes a hose body 1 and a mounting block 2. The hose body 1 is a low-temperature resistant PVC hose with a layer of metal wire braided on its surface. The mounting block 2 is provided with a through groove 23 and a connecting part 4. The through groove 23 passes through the mounting block 2, and the connecting part 4 is a clamp 41. The clamp 41 passes through the through groove 23 and clamps the mounting block 2 onto the swing arm of the vehicle.

[0027] Reference Figures 2-4 A metal tube 11 is fitted and fixedly connected to the middle of the tube body 1. Springs 12 are provided at both ends of the metal tube 11, and both springs 12 are fitted onto the tube body 1. A mating hole 21 is provided on the mounting block 2, through which the tube body 1 and the metal tube 11 pass. Two sliding grooves 24 are provided on the wall of the mating hole 21, symmetrically arranged, and sliding rods 25 are installed within each groove 24.

[0028] Reference Figures 2-4 One end of the slide rod 25 extends into the mating hole 21 and is provided with a clamping block 22. The two clamping blocks 22 are located on the periphery of the metal tube 11. Threaded holes 26 are opened on the side of the two clamping blocks 22 facing away from the tube body 1. One end of the slide rod 25 is slidably connected in the slide groove 24 along the axis perpendicular to the mating hole 21, and the other end of the slide rod 25 is threadedly connected in the threaded hole 26.

[0029] Reference Figures 2-4 The mounting block 2 is also equipped with a driving unit 3, which drives multiple clamping blocks 22 to move toward the tube body 1 so that two clamping blocks 22 clamp the metal tube 11. The driving unit 3 includes two rotating tubes 31, a first conical surface 32 provided on the inner wall of the rotating tubes 31, and a second conical surface 33 provided on both ends of the clamping blocks 22. The inner walls of the two openings of the mating holes 21 are provided with threads, and the two rotating tubes 31 are respectively threaded into the openings of the two mating holes 21. At the same time, the tube body 1 and the metal tube 11 pass through the two rotating tubes 31 respectively.

[0030] Reference Figures 2-4 The first conical surface 32 on the inner wall of the two rotating tubes 31 abuts against the second conical surface 33 on the same side of the two clamping blocks 22. When the rotating tubes 31 are rotated to screw into the mating hole 21, the first conical surface 32 presses against the second conical surface 33, driving the clamping plate to move toward the metal tube 11 and clamp the metal tube 11, thereby fixing the metal tube 11 and the tube body 1 on the mounting block 2.

[0031] Reference Figures 1-4 When fixing the tube body 1, first pass the tube body 1 and the metal tube 11 through the rotating tube 31, the mating hole 21, and the rotating tube 31 in sequence. Then, screw the two rotating tubes 31 so that the two clamping blocks 22 move closer together to clamp the metal tube 11, and multiple clamping blocks 22 clamp the metal tube 11. After the metal tube 11 is clamped, pass the clamping ring 41 through the through groove 23 and clamp it onto the swing arm 5 of the car to complete the fixing of the tube body 1.

[0032] Of course, the above are just typical examples of this application. In addition, this application may have many other specific implementation methods. All technical solutions formed by equivalent substitution or equivalent transformation fall within the scope of protection claimed in this application.
