[0002] When a motorcycle is running at high speed, the performance of the braking system is directly related to the safety of the driver and passengers. Brake fluid, as a key component of the braking system, plays the role of transmitting brake pressure. During the maintenance and repair of motorcycle brake systems, the replacement and filling of brake fluid are key steps. The motorcycle brake fluid vacuum filling gun is a brake fluid filling tool designed specifically for motorcycles. It uses vacuum technology to achieve safe and accurate addition of brake fluid.

[0003] A Chinese patent publication (publication number: CN217103062U) discloses a novel motorcycle brake fluid filling gun, belonging to the field of brake fluid technology. The gun comprises a fluid tank, a U-shaped plate located on one side of the fluid tank, and a force-bearing plate located below the fluid tank. A push rod is movably connected to one side of the fluid tank, a push plate is connected to one side of the push rod, and the push plate is in contact with the inner side wall of the fluid tank. A spring is connected to the inner side wall of the U-shaped plate, and an extrusion plate is connected to the side of the spring away from the U-shaped plate. A limiting module is provided on the inner side of the U-shaped plate, and a slot is provided on the outer side of the push rod.

[0004] The aforementioned reference document, when in use, primarily places a fluid tank on a support plate, connects a filling pipe to the motorcycle's filling port, and then uses a turning handle to rotate a threaded rod, thereby pushing a slide rod and an extrusion plate to inject brake fluid into the motorcycle's brake system, thereby achieving automated brake fluid filling. However, during use, the reference document places the fluid tank directly on the support plate, lacking effective fixing and limiting measures. This may cause the fluid tank to shake unnecessarily during operation, thereby affecting the accurate filling of the brake fluid.

[0005] In view of this, the utility model solves the above technical problems by proposing a vacuum filling gun for motorcycle brake fluid. Utility Model Content

[0025] The following will be combined with the drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the embodiments described are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without making creative efforts are within the scope of protection of the present invention.

[0026] Example 1:

[0027] See also Figure 1-5As shown, a brake fluid vacuum filling gun for motorcycles comprises a base plate 1, a liquid tank 101, a filling pipe 102 and a push plate 103. A fixing assembly is fixed to opposite surfaces of the inner cavity of the base plate 1 for effectively fixing and limiting the liquid tank 101. The fixing assembly comprises two connecting shafts 2, which are fixed to opposite surfaces of the inner cavity of the base plate 1. The surfaces of the two connecting shafts 2 are rotatably connected to connecting columns 201. The inner cavity of the connecting column 201 is rotatably connected to a splint 202. A circular shaft 203 is fixed to the opposite surface of the inner cavity of the connecting column 201. The surface of the circular shaft 203 is slidably connected to a movable plate 204. A pull rod 205 is fixed to the bottom end of the movable plate 204. A reset spring 206 is fixed to the opposite surface of the pull rod 205 and the base plate 1. A screw rod 3 is rotatably connected to the surface of the base plate 1. A knob 301 is fixed to one end of the screw rod 3. The surface of the knob 301 is rotatably connected to an anti-accidental touch assembly for preventing operation. The author accidentally turns the knob 301, causing the brake fluid to overflow accidentally. The anti-mistouch component includes an outer cover 4, which is rotatably connected to the surface of the knob 301, and one end of the knob 301 is provided with multiple slots 401, and one end of the inner cavity of the outer cover 4 is fixed with multiple blocks 402. One end of the knob 301 outside the slot 401 is fixed with a limit spring 403, and the other end of the screw rod 3 extends to the inner cavity of the bottom plate 1. The surface of the screw rod 3 is threadedly connected with a pressure plate 5, and the outer cover 4 is provided with anti-slip grooves. By setting the anti-slip grooves, the anti-slip effect can be achieved when the outer cover 4 is rotated. One end of the return spring 206 is fixedly connected to one end of the pull rod 205, and the other end of the return spring 206 is fixedly connected to the bottom end of the inner cavity of the bottom plate 1. The liquid tank 101 is arranged in the inner cavity of the splint 202, the filling pipe 102 is fixed to one end of the liquid tank 101, and the push plate 103 is slidably connected to the inner cavity of the liquid tank 101.

[0028] When in use, first reset the pressing plate 5, then pull the pull rod 205 to compress the reset spring 206. The pull rod 205 moves downward to drive the movable plate 204 to move downward. Since the surface of the movable plate 204 is provided with a circular groove, when the movable plate 204 moves downward, the circular shaft 203 moves in the inner cavity of the circular groove. When the circular shaft 203 moves to the limit position, the pull rod 205 is pulled. At this time, the movable plate 204 drives the two connecting columns 201 to rotate. When the two connecting columns 201 rotate, the two splints 202 will be driven to open. At this time, the liquid tank 101 is installed in the inner cavity formed by the two splints 202, and one end of the push plate 103 is fitted with one end of the pressure plate 5. When the installation of the liquid tank 101 is completed, the pull rod 205 is released. The pull rod 205 moves upward under the extension force of the return spring 206, and drives the movable plate 204 to move upward. At this time, the circular shaft 203 moves again in the inner cavity of the circular groove. When After the circular shaft 203 moves to the limit position, the movable plate 204 will drive the two connecting columns 201 to rotate, so that the two clamping plates 202 are retracted, and the liquid tank 101 is fixed and limited. When the liquid tank 101 is fixed and limited, the filling pipe 102 is connected to the filling port on the motorcycle. At this time, the outer cover 4 is pressed and rotated to squeeze the limit spring 403 at one end of the inner cavity of the outer cover 4. As the outer cover 4 rotates, when the block 402 is aligned with the slot 401, the block 402 is pressed. The outer cover 4 will then continue to rotate, and the outer cover 4 will drive the knob 301 to rotate. The rotation of the knob 301 will drive the screw rod 3 to rotate. The rotation of the screw rod 3 will drive the pressure plate 5 to move. The movement of the pressure plate 5 will push the push plate 103. The movement of the push plate 103 will push the brake fluid in the inner cavity of the liquid tank 101 to the inner cavity of the filling pipe 102, and enter the motorcycle through the inner cavity of the filling pipe 102, thereby completing the filling of the motorcycle's brake fluid.
