Description

Technical Field

[0001] The utility model relates to the technical field of motorcycle direct-push upper pumps, in particular to a motorcycle direct-push upper pump with a central valve structure. Background Art

[0002] A direct-push upper pump means that the direction of movement is consistent with the direction of the handle, which is a linear braking relationship. Currently, large-displacement cars in the liter class all use a direct-push upper pump. The upper pump is used to store brake oil. When braking, the brake handle is operated to generate hydraulic pressure, which drives the lower pump to press the brake friction pads and clamp the brake discs on the front wheels to achieve braking. There will be an oil pot on the ice of the direct-push upper pump. Its purpose is to increase the depth of the oil pot to prevent air from entering the brake oil pipe when tilting at a large angle.

[0003] The utility model patent application document with publication number "CN221251620U" discloses a motorcycle direct-push upper pump with a central valve structure, wherein one end of the piston in the valve body has an accommodating chamber, and a central valve core is provided in the accommodating chamber for relative sliding along the axial direction of the piston. A spring acts on one end of the central valve core, and a guide rod extends from the other end thereof toward the end away from the spring. The guide rod passes through the accommodating chamber and is inserted into the piston, and can be detachably pressed against a limit portion provided in the valve body. An avoidance groove is provided on the piston corresponding to the limit portion, and the avoidance groove is provided along the axial direction of the piston; a channel connecting to the oil cup in the valve body is formed between the guide rod and the piston, and a gap connected to the channel is formed between the end of the central valve core corresponding to the guide rod and the inner side surface of the accommodating chamber; there is no lateral small hole in the area of ​​the valve body corresponding to the movement of the piston, and the closing method is through the contact and sealing of the central valve core and the piston, rather than the main leather cup exceeding the small hole; in this way, even if the ABS is activated during braking and the piston moves back and forth at a high frequency, the main leather cup will not be damaged.

[0004] The motorcycle direct-push upper pump with a central valve structure disclosed in the above-mentioned document has the following defects: the angle length of the motorcycle direct-push upper pump control handle in this technical solution is fixed, and if the palm is large or small, it will feel uncomfortable to grasp, resulting in relatively low comfort of use.

[0005] It can be seen from this that the existing motorcycle direct-push top pump with a central valve structure does not have a structure for adjusting the handle, and it is necessary to improve the existing shortcomings and provide a motorcycle direct-push top pump with a central valve structure.

A connecting sleeve is fixedly installed at one end of the adjustment plate, and a first through slot is provided on one side of the connecting sleeve.

[0011] Furthermore, the control handle assembly includes a control handle body, a rubber pad is fixedly mounted on the outer surface of the control handle body, and a connecting block is fixedly mounted on one end of the control handle body.

[0012] Furthermore, a second through groove is formed on the outer surface of the connecting block, the connecting block is plugged into the inner wall of the connecting sleeve, and the second through groove is communicated with the first through groove.

[0013] Furthermore, an insert rod is inserted into the interior of the connecting block and the first through slot, and the connecting block is rotatably connected to the first through slot through the insert rod. A threaded groove is provided at one end of the insert rod, and a threaded locking cap is threadedly connected to the outer surface of the threaded groove, and the threaded locking cap is in contact with the connecting sleeve.

[0014] The utility model has the following beneficial effects:

[0015] (1) The utility model is connected to the inner wall of the valve body by rotating the handle plug-in shell, and the plug-in slot at one end thereof cooperates with the adjustment plate, and the adjustment plate is connected to the bolt in the first connection slot through the positioning hole to achieve position fixation. When the adjustment plate moves in the plug-in slot, it can be matched with different positioning holes by the bolt to change the overall length of the control handle body. The control handle body in the control handle assembly is connected to the connection sleeve through the connecting block, and the second through slot of the connecting block is aligned with the first through slot. The plug rod passes through the first through slot and the second through slot and is fixed by the threaded locking cap to achieve the connection between the control handle assembly and the installation assembly. The control handle body enhances the grip comfort through the rubber pad. The connection block at one end thereof cooperates with the connection sleeve of the adjustment plate. By adjusting the plug rod and the threaded locking cap, the locking state of the connection block can be released by loosening the threaded locking cap, and the connection block can be rotated around the plug rod, so that the angle of the control handle body can be adjusted. By the coordinated work of the installation assembly and the control handle assembly, the angle and length of the control handle body can be adjusted, which is suitable for palms of different sizes and improves the flexibility of use.
