Description

Technical Field

[0001] This utility model relates to the technical field of personal transportation tools, and specifically to an oil pipe structure for a hydraulic brake. Background Technology

[0002] Personal transportation tools refer to vehicles or auxiliary tools used for transportation, such as scooters. With the development of technology, electric scooters have emerged, along with corresponding braking systems. These braking systems include disc brakes, hydraulic brakes, and drum brakes. Hydraulic brakes, also known as hydraulic disc brakes, are braking systems that utilize hydraulic pressure to achieve braking. Therefore, they consist of a hydraulic hose connected to the brake lever. The hose has a bend at the connection point, requiring a hose sleeve. However, existing hose sleeves use ordinary rubber, which is relatively soft and prone to breakage, necessitating frequent replacements. Summary of the Invention

[0003] The purpose of this utility model is to provide a hydraulic brake oil pipe structure, wherein the oil pipe sheath is made of TPU material, and the oil pipe sheath has a hardness of 80° and is elastic, thus having good hardness and elasticity, thereby avoiding the situation of being too soft or too hard, and thus better protecting the oil pipe, thus solving the problem that the existing oil pipe sheath material is too soft and easy to break.

[0004] The purpose of this utility model is achieved as follows:

[0005] A hydraulic brake hose structure includes a mounting base for mounting on a vehicle frame, with a rotatable brake handle on one side of the mounting base and an hose connected to the other side of the mounting base. An hose sheath is fitted over the connection between the mounting base and the hose, and the hose sheath is made of TPU material with a hardness of 80° and elasticity.

[0006] Preferably, the tubing sheath is a corrugated pipe at the end closest to the tubing.

[0007] Preferably, the mounting base is connected to the oil pipe via a nut, and the inner wall of the oil pipe sheath fits against the outer side of the nut.

[0008] Preferably, the outer side of the tubing sheath is provided with a protrusion to increase its thickness.

[0009] Preferably, the mounting base is provided with a rotating shaft, and the brake handle is sleeved on the outside of the rotating shaft and rotates around the rotating shaft. The brake handle is provided with a connecting shaft, and the mounting base is provided with a fixed shaft. Fasteners pass through the connecting shaft and are threadedly connected to the fixed shaft.

[0010] Preferably, the mounting base includes a main body and a fixing block, and the main body and the fixing block are provided with arc-shaped grooves corresponding to the vehicle frame, and the main body and the fixing block are connected by fasteners.

[0011] The outstanding and beneficial technical effects of this utility model compared to the prior art are:

[0012] The oil pipe sheath of this utility model is made of TPU material, and the hardness of the oil pipe sheath is 80° and it is elastic. Therefore, it has good hardness and elasticity, thus avoiding the situation of being too soft or too hard, and thus better protecting the oil pipe. Attached Figure Description

[0019] The specific embodiments of this utility model will be further described in detail below with reference to the accompanying drawings.

[0020] like Figures 1-4 As shown, a hydraulic brake hose structure includes a mounting base 1 for mounting on a vehicle frame, a rotatable brake handle 2 on one side of the mounting base 1, and an oil hose connected to the other side of the mounting base 1. An oil hose sheath 3 is fitted on the outside of the connection between the mounting base 1 and the oil hose. The oil hose sheath 3 is made of TPU material and has a hardness of 80° and is elastic.

[0021] Therefore, in actual use, since the oil pipe sheath 3 is made of TPU material and has a hardness of 80° and elasticity, it has good hardness and elasticity, thus avoiding the situation of being too soft or too hard, and thus better protecting the oil pipe.

[0022] Secondly, thermoplastic polyurethane elastomer, also known as thermoplastic polyurethane rubber or TPU for short, is a type of elastomer that can be plasticized by heating and dissolved by solvents. It has excellent comprehensive properties such as high strength, high toughness, wear resistance, and oil resistance, and has good processing performance. It is widely used in defense, medical, food and other industries.

[0023] Meanwhile, the detailed structure of the tubing sheath 3 is as follows: Firstly, the end of the tubing sheath 3 closest to the tubing is a corrugated pipe 32. Therefore, in actual use, it can play a buffering role, and it can also be slightly lengthened or shortened to accommodate different lengths.

[0024] Furthermore, the mounting base 1 is connected to the oil pipe via the nut 5, and the inner wall of the oil pipe sleeve 3 fits snugly against the outer side of the nut 5. Therefore, in actual use, this provides better protection for the connection between the mounting base 1 and the oil pipe. While this invention primarily protects the oil pipe sleeve 3 and emphasizes the fit between the inner wall of the oil pipe sleeve 3 and the outer side of the nut 5, the specific connection between the nut 5 and the oil pipe is not the focus of this invention. Moreover, the connection between the nut 5 and the oil pipe is existing technology, and therefore it is not fully illustrated in the accompanying drawings and is not described in detail.

[0025] Furthermore, the outer side of the oil pipe sheath 3 is provided with a protrusion 31, which increases the thickness and thus provides better protection. Moreover, this corresponds to the nut 5, so the connection between the mounting base 1 and the oil pipe can be better protected.

[0026] like Figures 1-4 As shown, the structure between the mounting base 1 and the brake handle 2 is as follows: First, a rotating shaft 6 is provided on the mounting base 1, and the brake handle 2 is sleeved on the outside of the rotating shaft 6 and rotates around the rotating shaft 6. At the same time, a connecting shaft 7 is provided on the brake handle 2, and a fixing shaft 8 is provided on the mounting base 1. Fasteners pass through the connecting shaft 7 and are threadedly connected to the fixing shaft 8. The fasteners are screws.

[0027] Therefore, in actual use, the rotational connection is achieved through the rotating shaft 6. Simultaneously, by rotating the fastener, the relative position between the fastener and the fixed shaft 8 can be adjusted, thereby regulating the rotation range of the brake handle 2. This is because there is a certain gap between the connecting shaft 7, the fixed shaft 8, and the fastener; that is, the connecting shaft 7 can move on the fixed shaft 8 and the fastener. This range of movement is the rotation range of the brake handle 2. Furthermore, the head of the fastener prevents the connecting shaft 7 from detaching from the fixed shaft 8. Therefore, adjusting the relative position between the fastener and the fixed shaft 8 adjusts the range of movement of the connecting shaft 7, thereby regulating the rotation range of the brake handle 2.

[0028] Meanwhile, the mounting base 1 itself has the following structure: First, the mounting base 1 includes a main body 11 and a fixing block 12, and the main body 11 and the fixing block 12 are provided with arc-shaped grooves corresponding to the vehicle frame, and the main body 11 and the fixing block 12 are connected by fasteners. The fasteners are screws.

[0029] The foregoing has shown and described the basic principles, main features, and advantages of this utility model. However, this utility model is not limited to the above embodiments; therefore, various changes and modifications can be made without departing from the principles and scope of this utility model, and all such changes and modifications fall within the scope of the claimed utility model.
