Description

Technical Field

[0001] This utility model relates to the field of automotive pipeline fixing technology, and in particular to an automotive brake pipe fixing clamp. Background Technology

[0002] With the development of the automotive industry and the continuous improvement of product quality requirements, brake clamps are increasingly being used to secure automotive brake lines. Brake clamps are typically made of metal or other corrosion-resistant materials, featuring a simple yet robust design and excellent load-bearing capacity. They firmly fix the brake lines in a designated position through a fastening device, ensuring that the brake lines will not loosen or shift due to external forces during vehicle operation, effectively avoiding the risk of brake system leakage or failure.

[0003] In actual use, the clamps may loosen during long-term driving. If the loosening is severe, it may cause the seal at the brake pipe joint to fail, resulting in brake fluid leakage. The drop in brake fluid level will prevent the braking system from working properly. At the same time, the leaked brake fluid may contaminate the tires, the ground, etc., affecting the vehicle's handling performance and driving safety. Utility Model Content

[0004] The purpose of this utility model is to provide a car brake pipe fixing clamp. When the clamping block is inserted into the first limiting groove on the outer surface of the fastening nut, it can effectively prevent the fastening nut from rotating, thereby preventing the clamp from loosening due to vibration during vehicle operation, ensuring that the brake pipe is always in a stable fixed state, and ensuring the reliability of the braking system.

[0005] To achieve the above objectives, a brake pipe fixing clamp is provided, comprising: a tension clamp, a second limiting post fixedly connected to the outer surface of the tension clamp, a second rotating post rotatably connected to the inner surface of the second limiting post, a fastening nut fixedly connected to the second rotating post by bolts, a first mating groove formed on the outer surface of the second limiting post, second limiting grooves provided on both the front and rear sides of the outer surface of the first mating groove, a locking block slidably connected to the inner surface of the second limiting groove, and six first limiting grooves formed on the outer surface of the fastening nut, the first limiting grooves engaging with the locking blocks. This structural design allows the components to cooperate with each other, realizing clamp tension adjustment and locking of the fastening state, ensuring stable fixing of the brake pipe.

[0006] According to the aforementioned automotive brake pipe fixing clamp, the interior of the second limiting groove is connected to the interior of the first mating groove, and the six first limiting grooves are circumferentially distributed on the outer surface of the fastening nut. This connected and circumferentially distributed design facilitates the insertion of the locking block into the limiting groove, improving the clamp's adjustment flexibility and stability.

[0007] According to the aforementioned automotive brake pipe fixing clamp, the interior of the second limiting groove and the outer surface of the second limiting post are connected, and the inner surface of the fastening nut and the inner surface of the first mating groove abut against each other. This connection and abutment design facilitates the installation of the clamping block while restricting the axial movement of the fastening nut, thus enhancing the reliability of the clamp.

[0008] According to the aforementioned automotive brake pipe fixing clamp, a first limiting post is fixedly connected to the outer surface of the clamp away from the second limiting post. A first rotating post is rotatably connected to the inner surface of the first limiting post, and the interior of the first rotating post is slidably connected to the bolt. The first limiting post and the first rotating post cooperate to balance the force on the bolt and help the clamp to be adjusted smoothly.

[0009] According to the aforementioned automotive brake pipe fixing clamp, an abutment sealing block is engaged on the inner surface of the clamp, and a second mating groove is formed on the inner surface of the abutment sealing block. The design of the abutment sealing block and its second mating groove seals the brake pipe and buffers friction, protecting the brake pipe from damage.

[0010] The above-mentioned solution has the following beneficial effects:

[0011] This utility model is provided with a first mating groove, a second limiting groove, a snap-fit ​​block, a fastening nut, and a second limiting post. When the snap-fit ​​block is snapped into the first limiting groove on the outer surface of the fastening nut, it can effectively prevent the fastening nut from rotating, thereby preventing the clamp from loosening due to vibration during vehicle operation, ensuring that the brake pipe is always in a stable fixed state, and guaranteeing the reliability of the braking system.

[0020] This section will describe in detail the specific embodiments of the present utility model. The preferred embodiments of the present utility model are shown in the accompanying drawings. The purpose of the drawings is to supplement the textual description with graphics, so that people can intuitively and vividly understand each technical feature and the overall technical solution of the present utility model, but they should not be construed as limiting the scope of protection of the present utility model.

[0021] Reference Figure 1-4 This utility model discloses a car brake pipe fixing clamp, comprising: a tensioning clamp 1, with a second limiting post 7 fixedly connected to the outer surface of the tensioning clamp 1. The second limiting post 7 not only serves as the rotation fulcrum of a second rotating post 8, but also provides an attachment base for a first mating groove 11 and a second limiting groove 12, thus constructing a connecting bridge between the clamping block 6 and the fastening nut 9. The inner surface of the second limiting post 7 is rotatably connected to a second rotating post 8, which rotates about the second limiting post 7 as an axis, and drives the fastening nut 9 to move with the help of bolts 5. The tightness of the clamp 1 is then adjusted to work in conjunction with the first rotating column 4 to adjust the clamp's tightness. The second rotating column 8 is fixedly connected to a fastening nut 9 by bolts 5. Bolts 5 convert the rotational motion of the second rotating column 8 into the linear displacement of the fastening nut 9. By tightening or loosening, the circumference of the clamp 1 is changed to accommodate the fixing of brake pipes of different diameters. The outer surface of the second limiting column 7 has a first mating groove 11, which tightly abuts against the outer surface of the fastening nut 9, restricting its axial movement and engaging with the locking block. The engagement of the locking block 6 with the first limiting groove 10 prevents the fastening nut 9 from rotating accidentally and ensures the stability of the clamp's tightness. The outer surface of the first mating groove 11 has second limiting grooves 12 on both the front and rear sides. These second limiting grooves 12 not only provide a sliding track for the locking block 6 but also, through communication with the first mating groove 11, ensure that the locking block 6 can smoothly engage with the first limiting groove 10 of the fastening nut 9, thus locking the fastening nut 9. The inner surface of the second limiting groove 12 is slidably connected to the locking block 6. The inner sliding mechanism, relying on the large friction between itself and the first limiting groove 10 and the tensile force formed by the structure between the two, firmly locks the fastening nut 9, preventing it from loosening due to vibration or other factors. The outer surface of the fastening nut 9 has six first limiting grooves 10, and the first limiting grooves 10 and the locking block 6 are engaged. The six circumferentially distributed first limiting grooves 10 provide multiple engagement positions for the locking block 6. Combined with the large friction between the two and the tensile limiting structure, it meets the locking requirements of different tightness of the clamp, improving the applicability and stability of the clamp.

[0022] The interior of the second limiting groove 12 is connected to the interior of the first mating groove 11. This connection design creates a channel for the snap-fit ​​block 6 to enter the first limiting groove 10 from the second limiting groove 12, facilitating the locking operation of the snap-fit ​​block 6 on the fastening nut 9 and ensuring the smooth realization of the clamp locking function. The six first limiting grooves 10 are circumferentially distributed on the outer surface of the fastening nut 9. This circumferential distribution expands the snap-fit ​​selection range of the snap-fit ​​block 6. Regardless of the adjustment position of the fastening nut 9, the snap-fit ​​block 6 can engage with it, achieving effective locking through friction and pulling force. The interior of the second limiting groove 12 is connected to the outer surface of the second limiting post 7, forming a connection structure. The snap-fit ​​block 6 is installed externally into the second limiting groove 12 to ensure that during clamp assembly, the snap-fit ​​block 6 can smoothly participate in locking the fastening nut 9. The inner surface of the fastening nut 9 and the first mating groove 11 abut against each other, which restricts the axial movement of the fastening nut 9. Together with the snap-fit ​​block 6, the first limiting groove 10 and the second limiting groove 12, they enhance the overall stability of the clamp when fixing the brake pipe. The outer surface of the slack clamp 1 is fixedly connected to the first limiting post 3 on the side away from the second limiting post 7. The first limiting post 3 is set opposite to the second limiting post 7 and provides rotational support for the first rotating post 4. Together with the second rotating post 8 and other components, they constitute the clamp. The fastening and adjusting mechanism has a first rotating column 4 rotatably connected to the inner surface of the first limiting column 3, and the interior of the first rotating column 4 is slidably connected to the bolt 5. The first rotating column 4 rotates around the first limiting column 3 and slides along the bolt 5, coordinating with the action of the second rotating column 8 to balance the force on the bolt 5, so that the clamp remains stable during the adjustment of tightness. The inner surface of the tightening clamp 1 is engaged with an abutting sealing block 2. The abutting sealing block 2 engages with the tightening clamp 1, and when the clamp tightens the brake pipe, it adheres to the surface of the brake pipe, playing a sealing and buffering role to prevent damage to the brake pipe. The inner surface of the abutting sealing block 2 is provided with a second mating groove 13, which engages with the brake pipe. The shape is adapted to increase the contact area between the sealing block 2 and the brake pipe, further improving the sealing effect and ensuring the normal operation of the braking system. The friction of the snap-fit ​​block 6 in the first limiting groove 10 and the second limiting groove 12 is large, making it difficult for it to fall off by itself. In addition, the structure between the first limiting groove 10 and the second limiting groove 12 forms a pulling force to pull and limit the snap-fit ​​block 6. With the large friction between the snap-fit ​​block 6 and the first limiting groove 10 and the second limiting groove 12, as well as the pulling force formed by the structure of the first limiting groove 10 and the second limiting groove 12, the snap-fit ​​block 6 is effectively prevented from falling off by itself, and the locking nut 9 is continuously locked to maintain the stable fastening of the clamp to the brake pipe.

[0023] Working principle: First, the contact sealing block 2 is inserted into the inner surface of the elastic clamp 1. The second mating groove 13 inside the contact sealing block 2 can then fit the brake pipe, playing a sealing and buffering role when fixing the brake pipe to avoid damage to the brake pipe. The elastic clamp 1 with the contact sealing block 2 installed is wrapped around the part of the brake pipe that needs to be fixed, so that the brake pipe is located in the second mating groove 13. The bolt 5 is passed through the first rotating post 4 and the second rotating post 8 in sequence. The first rotating post 4 is rotatably connected to the first limiting post 3, and the second rotating post 8 is rotatably connected to the second limiting post 7. The bolt 5 can slide inside the first rotating post 4 to prepare for adjusting the tightness of the clamp. Rotate the second rotating post 8. Since the second rotating post 8 is fixedly connected to the fastening nut 9 by the bolt 5, its rotation will drive the bolt 5 to move the nut 9 to move the brake pipe to move the fastening ... Bolt 5 and fastening nut 9 move, while the first rotating column 4 rotates around the first limiting column 3 and slides along bolt 5. The two work together to change the circumference of the clamp 1, thereby tightening or loosening the brake pipe to match the diameter of the brake pipe. When the clamp reaches the appropriate tightness, the locking block 6 slides in the second limiting groove 12. The second limiting groove 12 is connected to the first mating groove 11. The locking block 6 can be smoothly locked into the first limiting groove 10 distributed circumferentially on the outer surface of the fastening nut 9. Due to the large friction between the locking block 6 and the first limiting groove 10 and the second limiting groove 12, as well as the pulling force formed by the structure of the first limiting groove 10 and the second limiting groove 12, the locking block 6 is prevented from falling off by itself, locking the fastening nut 9 and maintaining the clamp's tightness on the brake pipe.

[0024] The embodiments of the present utility model have been described in detail above with reference to the accompanying drawings. However, the present utility model is not limited to the above embodiments. Within the scope of knowledge possessed by those skilled in the art, various changes can be made without departing from the spirit of the present utility model.
