Description

Technical Field

[0001] This utility model relates to the field of automotive parts technology, specifically a buffer-type multi-bend brake joint. Background Technology

[0002] Automotive brake connectors are indispensable components in automobiles. The main body of the connector is generally made of metal, such as copper alloy or stainless steel, to ensure sufficient strength and corrosion resistance.

[0003] A search of patent application number CN200510005876.6 reveals that this improved brake connector prevents wear on parts due to slippage, thus improving the braking feel. In existing brake system piping connections, complex piping layouts requiring multiple bends often necessitate the use of multiple ordinary bend connectors for combined connections. This connection method has several problems, such as insufficient vibration damping, poor adaptability to bends, space limitations, cumbersome installation process requiring significant time and effort for positioning and assembly, and the combination of multiple connectors increases the risk of leakage, thereby reducing the reliability of the brake system.

[0004] Further searching patent application number CN202110312844.X reveals that the connector body is also suitable for receiving an elongated tube having a spherical / protruding flared end that passes through the inner holes of both the female and male ends. This spherical / protruding flared end extends outward from a first opening at the head end, with the spherical / protruding flared end resting against the adjacent surface. In existing braking system piping connections, complex piping layouts requiring multiple bends often necessitate the use of multiple ordinary bend connectors for combined connections. This connection method presents numerous problems, such as insufficient vibration damping capacity, poor adaptability to bends, space limitations, cumbersome installation process requiring significant time and effort for positioning and assembly, etc. Furthermore, the combination of multiple connectors increases the risk of leakage, thereby reducing the reliability of the braking system. Utility Model Content

[0005] To address the shortcomings of existing technologies, this invention provides a buffer-type multi-bend brake joint. The joint utilizes multiple bends in the curved pipe, effectively absorbing vibration, impact, and pressure from thermal expansion and contraction, thus providing a buffering effect. A certain distance exists between each adjacent bend, allowing sufficient cooling time for the coolant and ensuring braking effectiveness. Each bend has a specific bending angle and direction, and each bend is wrapped with a rubber sleeve. This sleeve protects the outer surface of the curved pipe from coolant corrosion at the bend, extending the pipe's lifespan. This invention solves the problem of existing braking system piping connections, where complex layouts requiring multiple bends often necessitate the combination of multiple ordinary bend joints. This connection method has several drawbacks, such as insufficient vibration buffering capacity, poor adaptability to bends, space limitations, cumbersome installation requiring significant time and effort for positioning and assembly, and increased risk of leakage due to the combination of multiple joints, thereby reducing the reliability of the braking system.

[0006] To achieve the above objectives, this utility model is implemented through the following technical solution: a buffer-type multi-bend brake joint, comprising a curved pipe and a square joint, wherein multiple protective shells are provided on the outer side of the curved pipe, the number of protective shells is multiple sets, and each set contains two protective shells, the inner walls of the two protective shells are provided with rubber sleeves.

[0007] Each of the protective shells is fixedly provided with a mounting plate at its top and bottom, and mounting screws are provided above and below the curved pipe. The shape and bending angle of each of the protective shells are different. A hole is provided on one side surface of the square joint, and a sealing ring is provided inside the hole. One end of the curved pipe extends into the inside of the sealing ring.

[0008] Preferably, the rubber sleeve is in contact with the inner wall of the protective shell and the curved pipe respectively, and a sleeve is provided at the end of the curved pipe away from the block joint.

[0009] Preferably, a bracket is fixedly provided on one side of the sleeve, and the surface of the bracket is provided with mounting holes.

[0014] Preferably, one side surface of the baffle and one side surface of the protective shell are vertically collinear, and the baffle is in contact with the curved pipe.

[0015] Preferably, the mounting screw penetrates the mounting plate and is threadedly connected to the mounting plate. Beneficial effects

[0016] This invention provides a buffer-type multi-bend brake joint. Compared with the prior art, it has the following advantages:

[0017] 1. This buffer-type multi-bend brake joint features multiple bends in the curved pipe. The bending structure effectively absorbs the pressure from vibration, impact, and thermal expansion and contraction, providing a buffering effect. A certain distance exists between each adjacent bend, allowing sufficient cooling time for the coolant and ensuring braking effectiveness. Each bend has a specific bending angle and direction, and each bend is wrapped with a rubber sleeve. This sleeve protects the outer surface of the curved pipe from coolant corrosion at the bend, extending the pipe's lifespan.

[0018] 2. This buffer-type multi-bend brake joint can be gradually separated from the mounting plate by rotating the mounting screws. After separation, because the two protective shells are in contact, the distance between the two protective shells can be increased, allowing the rubber sleeve and baffle to be removed. The rubber sleeve is in contact with both the protective shell and the baffle, allowing it to be removed and replaced. Attached Figure Description

[0025] 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.

[0026] Please see Figure 1-4 This utility model provides a technical solution: a buffer-type multi-bend brake joint, including a curved pipe 1 and a square joint 2. Multiple protective shells 3 are provided on the outer side of the curved pipe 1. The number of protective shells 3 is multiple sets, and each set of protective shells 3 has two protective shells 3. The inner walls of the two protective shells 3 are provided with rubber sleeves 4.

[0027] Each protective shell 3 has a mounting plate 5 fixedly installed on its top and bottom, and mounting screws 6 are installed above and below the curved pipe 1. Each protective shell 3 has a different shape and bending angle. A hole 7 is provided on one side surface of the square connector 2, and a sealing ring 8 is provided inside the hole 7. One end of the curved pipe 1 extends into the inside of the sealing ring 8.

[0028] The rubber sleeve 4 contacts the inner wall of the protective shell 3 and the curved pipe 1 respectively. A sleeve 9 is provided at the end of the curved pipe 1 away from the square joint 2. A bracket 10 is fixedly provided on one side of the sleeve 9, and the surface of the bracket 10 is provided with mounting holes 11. A round hole 12 is provided on the top surface of the square joint 2. The round hole 12 is connected to the hole 7. A groove 13 is provided on one side of the round hole 12, and the groove 13 is connected to the curved pipe 1.

[0029] Please see Figure 1-4 Each protective shell 3 has a baffle 14 at both ends, and the baffle 14 is fixedly connected to the protective shell 3. The cross-sectional shape of the baffle 14 is arc-shaped. The baffle 14 is in contact with the rubber sleeve 4. One side surface of the baffle 14 is vertically collinear with one side surface of the protective shell 3. The baffle 14 is in contact with the curved pipe 1. The mounting screw 6 passes through the mounting plate 5 and is threadedly connected to the mounting plate 5. When the rubber sleeve 4 needs to be replaced, the mounting screw 6 is rotated, which can gradually separate it from the mounting plate 5. After separation, because the two protective shells 3 are in contact, the distance between the two protective shells 3 can be increased, and the rubber sleeve 4 and the baffle 14 can be removed. The rubber sleeve 4 is in contact with both the protective shell 3 and the baffle 14, and can be removed and replaced.

[0030] During operation, the bracket 10 is first installed in the designated position. Then, the external bolts pass through the mounting holes 11 on the surface of the bracket 10 to install it stably on the designated surface. The bracket 10 is then bent and placed inside the groove 13, contacting the square connector 2. This allows the bent bracket 10 to directly contact the square connector 2. Compared to the conventional method of connecting the square connector 2 and the bracket 10 separately, the groove 13 design reduces the number of bent brackets and their space occupation while ensuring the correct orientation of the bent bracket 10, resulting in a more compact system layout. When the coolant flows in the bent pipe 1, the multiple bends in the pipe effectively absorb vibration, impact, and pressure from thermal expansion and contraction. Furthermore, the distance between each adjacent bend provides adequate cooling for the coolant. The design ensures braking effectiveness, and each bend has a specific bending angle and direction. The multiple bends allow the joint to flexibly adapt to different bend connection requirements, reducing stress concentration caused by bends and ensuring the sealing and strength of the braking pipeline. Each bend is wrapped with a rubber sleeve 4, which prevents the coolant from corroding the bend of the bend and improves the life of the bend. To replace the rubber sleeve 4, the mounting screw 6 is turned to gradually separate it from the mounting plate 5. After separation, since the two protective shells 3 are in contact, the distance between the two protective shells 3 can be increased, allowing the rubber sleeve 4 and the baffle 14 to be removed. The rubber sleeve 4 is in contact with both the protective shell 3 and the baffle 14, allowing it to be removed and replaced.

[0031] Furthermore, any content not described in detail in this specification is existing technology known to those skilled in the art.
