Description

TECHNICAL FIELD

[0001] The application relates to the technical field of brake line guide pipes, in particular to a guide pipe structure for improving brake line sensitivity. BACKGROUND

[0002] As a key component of vehicle safety, the performance of the brake system directly affects the safety of the driver and passengers. In the brake system, the brake line is responsible for transmitting the brake intention of the driver to the brake mechanism, so the sensitivity and reliability of the brake line are crucial. However, in practical applications, brake line guide pipes often face various challenges, especially in harsh driving environments such as wet, dusty or corrosive environments, and these challenges are more pronounced.

[0003] Most traditional brake line guide pipe structures use fixed sealing methods. Since the sealing structure is fixed, it cannot be flexibly adjusted according to the actual diameter of the brake line or the installation environment, limiting the versatility of the brake line guide pipe in different vehicles and scenarios. Moreover, the fixed sealing method cannot adapt to the slight deformation of the brake line under different working conditions, resulting in a gradual weakening of the sealing effect over time, and even the possibility of sealing failure. CONTENT OF THE UTILITY MODEL

[0004] In view of the deficiencies of the prior art, the application provides a guide pipe structure for improving brake line sensitivity, which has the advantages of traditional brake line guide pipe structures in terms of sealing performance and adjustability, and solves the problems raised in the background art.

[0005] To achieve the above-mentioned purpose, the application provides the following technical solution: a guide pipe structure for improving brake line sensitivity, comprising a brake line body, a plastic pipe externally sleeved on the brake line body, and an adjustable sealing assembly provided at both ends of the plastic pipe, the adjustable sealing assembly comprising four blades fixedly connected to the outer surface of the plastic pipe, a collar threadedly connected to the outer surface of the four blades, a rubber sleeve provided inside the four blades, three equally spaced micro ball bearings sleeved on the outer surface of the plastic pipe, a spiral metal layer sleeved on the outer surface of the plastic pipe, an annular arrangement metal layer sleeved on the outer surface of the spiral metal layer, and an outer shell sleeved on the outer surface of the annular arrangement metal layer.

[0006] Through the above-mentioned scheme, by setting the blades, collar and rubber sleeve, the four blades are tightly fitted on the brake line body by being squeezed by the collar, thereby effectively fixing brake line bodies of different sizes, and the degree of squeezing of the blades on the brake line body can be flexibly adjusted by rotating the collar, thereby adjusting the tightness of the fixation of the brake line body. The rubber sleeve effectively prevents external moisture, dust and other impurities from entering the inside of the guide pipe while adjusting the line, thereby improving the sealing performance of the guide pipe.

[0007] Furthermore, the four blades are distributed in a circular array at one end of the plastic tube.

[0008] Through the above solution, by arranging the blades, the blades distributed in a circumferential array can make the force more uniform, thereby improving the stability of the fixation.

[0009] Furthermore, the outer surfaces of the four blades are fixedly connected to the first bracket, and the outer surface of the rubber sleeve is hung on the outer surface of the first bracket.

[0010] With the above solution, the blades are provided to drive the first bracket to move, thereby driving the first bracket to fix and seal brake cable bodies of different diameters.

[0011] Furthermore, the adjustable sealing assembly further includes a second bracket, the outer surface of the second bracket is fixedly connected to the inner wall of the plastic tube, and the outer surface of the rubber sleeve is fixedly connected to the outer surface of the second bracket.

[0012] With the above solution, by providing the second bracket, the other end of the rubber sleeve can be fixed, thereby ensuring that the rubber sleeve is stably unfolded into a ring shape.

[0013] Furthermore, two rubber rings are fixedly connected to the inner wall of the shell, the through holes opened on both sides of the shell are adapted to the outer diameter of the plastic tube, and the size of the rubber ring is adapted to the outer diameter of the plastic tube.

[0014] With the above solution, by providing the rubber ring, the outer shell is located at the openings at both ends of the rubber ring, thereby further enhancing the sealing, dustproof and waterproof effects.

[0015] Furthermore, the spiral metal layer has an outer shape of a spiral spring, and both ends of the spiral metal layer are fixedly connected to the inner wall of the shell.

[0016] Through the above solution, by setting up the spiral metal layer, a certain tension can be provided in the conduit to ensure that the brake line body remains stable during operation. The spiral metal layer can also absorb vibration and impact during braking, further protecting the stability and reliability of the brake system.

[0017] Furthermore, the micro ball bearings are distributed in an array on the outer surface of the plastic tube, and there is a gap between the micro ball bearings and the inner wall of the spiral metal layer.

[0018] Through the above scheme, by setting up the role of micro ball bearings, the friction between the brake line and the conduit can be significantly reduced, making the braking operation smoother and more labor-saving, and there is a gap between the micro ball bearings and the inner wall of the spiral metal layer to prevent excessive extrusion from generating additional stress that damages the strength of the component.

[0019] Further, the material of the balls inside the three micro ball bearings is silicon carbide.

[0020] Through the above scheme, the service life of the micro ball bearing can be increased through the material properties of the balls, and the silicon carbide material can improve the corrosion resistance, high temperature resistance, wear resistance, running stability and working precision of the bearing.

[0021] Compared with the prior art, the technical scheme of the present application has the following beneficial effects:

[0022] The conduit structure for improving the sensitivity of the brake line can tightly fit on the brake line body through the squeezing of the four blades by the sleeve ring, so as to effectively fix the brake line body of different sizes, and the degree of squeezing of the blades on the brake line body can be flexibly adjusted by rotating the sleeve ring, so as to adjust the tightness of the fixation of the brake line body. The rubber sleeve can prevent impurities such as external moisture and dust from entering the inside of the conduit while adjusting the line, thereby improving the sealing performance of the conduit.
