DETAILED DESCRIPTION

[0019] The present application will now be described in further detail with reference to the accompanying drawings. It should be noted that the following specific embodiments are only used to further illustrate the present application and should not be construed as limiting the scope of protection of the present application. Those skilled in the art can make some non-essential improvements and adjustments to the present application based on the above application content.

[0020] like Figures 1-5 As shown, a closed-type adjustable hydraulic upper pump for disc brakes includes a disc brake upper pump body 1. A first oil pipe 3 is provided on one side of the disc brake upper pump body 1, and an oil pipe connector 17 is installed on one side of the disc brake upper pump body 1. One end of the first oil pipe 3 is connected to the oil pipe connector 17. The first oil pipe 3 is provided with an oil pipe bolt and an oil pipe washer. The oil pipe bolt is installed at the connection between the oil pipe connector 17 and the first oil pipe 3, and the oil pipe washer is placed on the oil pipe bolt. An installation cylinder 4 is installed at one end of the first oil pipe 3, and a second oil pipe 19 is installed at the bottom of the installation cylinder 4. A piston 5 is slidably connected inside the installation cylinder 4, and a fixing block 6 is installed on one side of the piston 5. A threaded sleeve 7 is installed on the outside of the installation cylinder 4, and a threaded rod 8 is rotatably connected inside the threaded sleeve 7. One end of the threaded rod 8 extends into the installation cylinder 4 and is connected to the fixing block. One side of the 6 is rotatably connected, and the other end of the threaded rod 8 is equipped with a rotating disk 9. The outside of the rotating disk 9 is equipped with an anti-slip pad. The disc brake upper pump body 1 is equipped with a mounting bracket 2. The mounting bracket 2 is movably connected with the brake handle 18. The first oil pipe 3 and the second oil pipe 19 are both connected to the mounting cylinder 4 and are correspondingly set. In the initial state, one side of the fixing block 6 is in contact with the inner wall of one side of the mounting cylinder 4. The disc brake upper pump body 1 includes an oil reservoir and a main oil pump body connected to the oil reservoir. The main oil pump body is slidably connected to the inside of the main oil pump body. A push rod is installed on one side of the brake handle 18. The push rod extends into the main oil pump body and is fixedly connected to the main oil pump piston. The oil pipe joint 17 is installed on the main oil pump body and is located on the side away from the brake handle 18. An elastic element, such as a spring, is installed between the main oil pump piston and the main oil pump body.

[0021] A fixed cylinder 10 is installed at the bottom of the mounting cylinder 4. A movable block 11 is slidably connected inside the fixed cylinder 10. A movable rod 12 is installed on one side of the movable block 11 and a spring 13 is installed on the other side. One end of the spring 13 is fixed to the inner wall of the fixed cylinder 10.
