[0027] The following will be combined with the drawings in the embodiments of the utility model to clearly and completely describe the technical solutions in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments in the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.

[0028] Reference Figure 1 - Figure 3 The utility model provides an embodiment: a brake pump assembly that is easy to disassemble and assemble, including a handbrake handle 1 and a mounting plate 2. The front surface of the mounting plate 2 is detachably connected to a mounting plate 21, and the mounting plate 2 supports the brake device. The handbrake handle 1 is detachably connected to the empty groove of the movable part of the mounting plate 2 by bolts. The left side of the upper surface of the handbrake handle 1 is detachably connected to a dial plate 101, and the right side of the upper surface of the mounting plate 2 is detachably connected to a brake wire box 3. The brake wire box 3 contains a control wire for controlling the brake, which controls the device. The upper surface of the brake wire box 3 is detachably connected to a cover plate 31, and a mounting tube 4 is welded to the right side of the lower surface of the mounting plate 2. When braking is required When in action, the user grips the handbrake handle 1 to deflect the handbrake handle 1, driving the paddle 101 to move, causing the paddle 101 to deflect and act on the brake control line in the brake line box 3. At this time, the brake control line in the mounting tube 4 is in a taut state, causing the air pressure in the brake control line to change, acting on the brake disc, and completing the braking effect on the device. When the staff needs to disassemble and maintain the brake assembly, the brake assembly can be separated and disassembled by loosening the fixing screws with tools, thereby reducing the cost of replacing and repairing the brake assembly for the user and providing convenience in installing and disassembling the brake assembly. The mounting tube 4 is provided with a protective component 5 on its surface.

[0029] Reference Figure 4 - Figure 5 and Figure 8When the brake control line collapses, the protection assembly 5 is activated. The protection assembly 5 includes a protection plate 51, which is detachably connected to the right surface of the mounting tube 4. The outer side of the axis of the right surface of the protection plate 51 is threadedly connected with a ring seat 52. The protection assembly 5 also includes a rubber clamp 53, which is fixedly connected to the outer side of the axis of the left side of the protection plate 51. The collapsed brake control line loses the function of the paddle 101 and falls off, so that the brake control line is about to be separated from the mounting tube 4. The rubber ring 531 is used to clamp the brake control line head. In order to provide a wrapping and obstructing effect, a rubber ring 531 is fixedly connected to the left end of the rubber clamp 53, the interior of the rubber clamp 53 is arranged as a hollow structure, the outer arc edge of the outer wall of the rubber clamp 53 is arranged as a rounded structure, and the inner ring of the rubber ring 531 is provided with a plurality of groups of evenly distributed anti-skid grooves 532. The impact force exerted on the rubber ring 531 is distributed through the rubber clamp 53, and the force exerted by the brake control line being detached is integrated, thereby ensuring the positioning and protective effect of the rubber ring 531 on the brake control line, and enhancing the protective effect of the brake device on the brake control line.

[0030] Reference Figure 6 - Figure 7 A rubber strip 521 is fixedly connected to the right surface of the circular ring seat 52, and a snap ring 522 is welded at the end of the rubber strip 521. When the brake control line is bent to varying degrees under the action of the handbrake grip 1, the rubber strip 521 cooperates to wrap the brake control line at the bending position, support and compensate for the bending force, and avoid the bending and aging of the outer wall of the brake control line. A positioning groove 523 is provided on the outer arc surface of the snap ring 522, and a clamping plate 524 is hinged on the outer arc surface of the snap ring 522. The clamping plate 524 is set to a semicircular arc strip structure, and the cross-sectional area of ​​the outer surface of the clamping plate 524 is adapted to the cross-sectional area of ​​the groove on the outer surface of the snap ring 522. By rotating the annular seat 52, the annular seat 52 is separated from the surface of the protective disc 51, and by moving the retaining ring 522, the rubber strip 521 acts on different bending parts of the brake control line, thereby improving the protection range of the protective device for the brake control line. A positioning block 525 is fixedly connected to the right side of the lower surface of the clamping plate 524, and the lower surface of the positioning block 525 is clamped in the inner wall of the positioning groove 523. When the brake control line needs to be fixed, the positioning block 525 in the clamping plate 524 cooperates with the positioning groove 523 to achieve the clamping and fixing effect on the outer side of the brake control line, thereby improving the maintenance and disassembly function of the brake control line by the staff and enriching the functionality of the device.

[0031] Working principle: when braking is required, the user squeezes the handbrake handle 1 to deflect the handbrake handle 1, driving the paddle 101 to move, causing the paddle 101 to deflect and act on the brake control line in the brake cable box 3, and the brake control line in the mounting tube 4 is in a taut state, causing the air pressure in the brake control line to change, acting on the brake disc, and completing the braking effect on the device. When the staff needs to disassemble and maintain the brake assembly, they can complete the separation and disassembly of the brake assembly by loosening the fixing screws with tools, reducing the cost of replacing and repairing the brake assembly for the user and providing convenience for installing and disassembling the brake assembly. When the brake control line collapses, the protective component 5 is activated, and the collapsed brake control line loses the effect of the paddle 101 and falls off, so that the brake control line is about to detach from the mounting tube 4, the rubber ring 531 wraps the brake control line head to hinder it, so that the brake control line cannot detach from the mounting tube 4, and the rubber ring 531 is protected The impact force is shared by the rubber clamping claw 53, which combines the force of the brake control line being separated, ensures the positioning and protection of the brake control line by the rubber ring 531, and enhances the protection effect of the brake device on the brake control line. When the brake control line is bent to different degrees under the action of the handbrake handle 1, the rubber strip 521 is used to wrap the bent part of the brake control line to support and compensate for the bending force, thereby avoiding the bending and aging of the outer wall of the brake control line. The annular seat 52 is separated from the surface of the protective plate 51 by rotating the annular seat 52, and the rubber strip 521 is used to act on different bending parts of the brake control line by moving the retaining ring 522, thereby improving the protection range of the protective device for the brake control line. When the brake control line needs to be fixed, the positioning block 525 in the clamping plate 524 cooperates with the positioning groove 523 to clamp and fix the outer side of the brake control line, thereby improving the maintenance and disassembly function of the brake control line by the staff and enriching the functionality of the device.
