Description

Technical Field

[0001] This invention relates to the field of brake structure technology, and more particularly to a manually adjustable hydraulic disc brake handle. Background Technology

[0002] Hydraulic disc brakes work by using hydraulic transmission. When the brake lever is pulled, the master cylinder pushes brake fluid into the brake pads, causing the pads to contact the brake disc and generate friction, thus achieving braking. This design makes the braking force transmission smoother, provides a better feel, and requires less force to achieve effective braking.

[0003] While existing hydraulic disc brake levers can be used conveniently for braking, they cannot be finely adjusted according to actual needs, making it difficult to adapt to different braking requirements. Therefore, a manually adjustable hydraulic disc brake lever is needed to solve the above problems. Summary of the Invention

The pin holes of the handle, connector, and master cylinder are aligned and a first pin passes through them. A first washer is fitted onto the pin holes. A first fastener is threaded onto the first pin and the connector to fix the first pin. A fine-tuning mechanism is mounted on the handle and threadedly connected to an intermediate connecting mechanism mounted on the connector. A tail-end connecting mechanism is mounted on the connector, and its power output end is close to a piston mounted inside the master cylinder.

[0006] Preferably, the fine-tuning mechanism includes: an adjusting nut that passes through the inner hole of the handle and is threadedly connected to the intermediate connecting mechanism; a compression spring is provided in the upper hole of the handle, and a knob is provided on the compression spring; and a flat-head screw that is threadedly connected to the adjusting nut to abut the knob.

Detailed Implementation

[0013] To make the objectives, technical solutions, and advantages of this invention clearer, the invention will be further described in detail below with reference to the accompanying drawings and embodiments. It should be understood that the specific embodiments described herein are merely illustrative of the invention and do not limit the invention.

[0014] The specific implementation of the present invention will be described in detail below with reference to specific embodiments.

[0015] Please see Figure 1 and Figure 2 The present invention provides a manually adjustable oil disc handle, the manually adjustable oil disc handle comprising:

[0016] The system comprises a handle 1, a connector 2, and a master pump 3. The handle 1 has an inner hole and an upper hole, the connector 2 has a square groove, and the handle 1, connector 2, and master pump 3 all have pin holes. The pin holes of the handle 1, connector 2, and master pump 3 are aligned and a first pin 4 passes through them. A first washer 5 is fitted onto the pin holes. A first fastener 6 is threaded onto the first pin 4 and connector 2 to fix the first pin 4. A fine-tuning mechanism 7 is mounted on the handle 1 and is threaded onto an intermediate connecting mechanism 8 mounted on connector 2. A tail-end connecting mechanism 9 is mounted on connector 2 and its power output end is close to a piston 10 mounted inside the master pump 3.

[0017] When using the manual adjustment disc brake handle, pull handle 1, and handle 1 will rotate on the master cylinder 3 via the first pin 4. This will cause the connecting piece 2 to rotate via the fine adjustment mechanism 7 and the intermediate connecting mechanism 8. The rotation of the connecting piece 2 will cause the tail connecting mechanism 9 to push the piston 10, thereby enabling the master cylinder 3 to complete the braking action.

[0018] like Figure 1 and Figure 2 As shown, in a preferred embodiment of the present invention, the fine-tuning mechanism 7 includes: an adjusting nut 71, which passes through the inner hole of the handle 1 and is threadedly connected to the intermediate connecting mechanism 8; a compression spring 72 is provided in the upper hole of the handle 1; and a knob 73 is provided on the compression spring 72; and a flat-head screw 74, which is threadedly connected to the adjusting nut 71 to abut against the knob 73.

[0019] The adjusting nut 71 passes through the inner hole of the handle 1, the compression spring 72 is placed in the upper hole of the handle 1, the knob 73 presses down the compression spring 72, and finally the flat-head screw 74 is tightened onto the adjusting nut 71 to fix the knob 73.

[0020] Grip width adjustment instructions: Turn knob 73 clockwise, connector 2 remains stationary, knob 73 causes handle 1 to descend, reducing the grip width of handle 1; turn knob 73 counterclockwise, connector 2 remains stationary, knob 73 causes handle 1 to rise, increasing the grip width of handle 1. When the optimal grip width is reached, the limit positions of handle 1 and connector 2 coincide, and knob 73 stops rotating counterclockwise. When adjusting the grip width of handle 1, knob 73 remains close to the upper end of handle 1 and will not move radially, and its appearance will not change.

[0021] like Figure 1 and Figure 2As shown, in a preferred embodiment of the present invention, the intermediate connecting mechanism 8 includes: two second washer 81s, which are assembled in the square groove of the connector 2, and an adjusting screw 82 is provided between the two second washer 81s. The adjusting screw 82 and the adjusting nut 71 are threadedly connected, and a second pin 83 passes through the second washer 81 and the adjusting screw 82; and a second fastener 84, which is installed on the adjusting screw 82 and is used to lock the adjusting screw 82 to press the second pin 83.

[0022] During assembly, the two second washer 81 are assembled into the two square slots. The adjusting screw 82 is placed in the middle of the two second washer 81 and aligned with the round hole of the two second washer 81. The second pin 83 is passed through the second washer 81 and the adjusting screw 82 in sequence. Then, the second fastener 84 is locked onto the adjusting screw 82, thereby pressing the second pin 83.

[0023] When assembling the handle 1, connector 2, and master pump 3, the adjusting screw 82 is locked into the adjusting nut 71, the pin holes of connector 2 and handle 1 are aligned with the pin holes of master pump 3, the first pin 4 is inserted and locked into the threads of connector 2 with the first fastener 6, thereby fixing the first pin 4.

[0024] like Figure 1 and Figure 2 As shown, in a preferred embodiment of the present invention, the tail end connecting mechanism 9 includes: a bushing 91, which is slidably mounted on the main pump 3, a connector 2 sleeved on the bushing 91, and a square nut 92 provided on the bushing 91; a push rod 93, which is connected to the bushing 91 through the square nut 92, and the push rod 93 is close to the piston 10 installed in the main pump 3.

[0025] Pulling handle 1 can rotate connector 2, which in turn drives push rod 93 to move via bushing 91. Push rod 93 can then push piston 10 to move within master cylinder 3, thereby enabling master cylinder 3 to brake.

[0026] The above description is only a preferred embodiment of the present invention and is not intended to limit the present invention. Any modifications, equivalent substitutions, and improvements made within the spirit and principles of the present invention should be included within the protection scope of the present invention.
