Referring to Figs. 1 and 2, the brake controller of the manpower pusher mainly includes a brake handle 1, wheels 2, wheel frame 3, brake seat 4 and brake cables 5, wherein the two brake handles 1 respectively control the two rear wheels 2 , and the braking devices placed on both sides of the left and right wheels are the same, so the braking states of the left and right sides can be controlled respectively in the same mode; A brake seat 4 is arranged on the corresponding side of the wheel frame 3, and a brake cable 5 is indirectly arranged between the brake seat 4 and the brake handle 1, which is longer than the straight line distance. The wheel 2 and the brake disc 21 are pivotally connected to the wheel frame through a shaft 3, the periphery of the brake disc 21 is provided with a tooth surface 211, and the wheel frame 3 is fixed with a guide block 32 on the inner side of a fixed bolt 31 to fit relatively with the groove 41 on the brake seat 4, and the brake seat 4 A long slot hole 42 is provided in cooperation with the penetration of the shaft rod 22, so that the brake seat 4 is relatively pivotally connected to the brake disc 21 of the wheel 2 of the wheel frame 3. In order to utilize the space of its groove 41 and the long slot hole 42 to have a certain displacement, the brake seat 4 is pushed by an elastic element 43 to abut against the lower edge of the brake disc 21 with the bottom end, and the brake seat 4 The bottom end is provided with a tooth body 44 meshing with the tooth surface 211 of the brake disc 21; in addition, one end of the brake cable 5 is fixedly connected to the brake seat 4 with the outer cable body 51, and the inner cable body 52 is movably inserted into the brake seat 4, And it is fixedly connected on the fixed bolt 31 on the wheel frame 3, and the other end of the cable 5 is then connected to the brake handle 1.

When the wheel 2 is operated at the end of the brake handle 1, the wheel is in the original normal state (as shown in Figure 1), and the brake seat 4 is pushed up by the elastic element 43, and its groove 41 and the slotted hole 42 are opposite to the guide on the wheel frame 3. The lead block 32 and the shaft rod 22 are in an upward positioning state. At the same time, the tooth body 44 at the bottom end of the brake seat 4 bites against the lower disc edge tooth surface 211 of the brake disc 21 and bites, so that the wheel 2 is braked.

Referring to Fig. 3, when the braked state of the wheel 2 needs to be released, the brake handle 1 can be pulled. Once the brake handle 1 is pulled, the inner cable body 52 of the brake cable 5 will be stretched, and the outer cable body 51 will be relatively offset. The pivot seat 11 of the brake handle 1 is pressed, so that the entire section of the outer cable body 51 has a compression effect to generate a deflection stretch and then push the brake seat 4 (see the direction of the arrow in the figure), compress the elastic element 43 and its groove 41. The slotted hole 42 is in a state of moving down relative to the guide block 32 and the shaft rod 22, and the tooth body 44 at the bottom of the brake seat 4 breaks away from the tooth surface 211 of the lower edge of the brake disc 21 to make the wheel 2 rotate.

The foregoing embodiments mainly use the brake handles 1 on the left and right sides to control the shape of the left and right wheels 2 respectively. In another active state, as shown in FIG. 4 , another tooth body 45 is formed at the top of the brake seat 4 , and the tooth body 45 corresponds to the tooth body 45 at the bottom end of the brake seat 4 . The state is the same as the separated state, there is a distance between the upper edge of the brake disc 21 and the other tooth body 45 formed on the top of the brake seat 4 (see Figure 7) and the release state can still be realized; moreover, as shown in Figures 5 and 6 As shown, if one of the brake handles 1 is pulled separately to control the release of the left and right wheels from the brake state, it is only necessary to use the brake device of the wheel to cooperate with an ad hoc turntable to tap the brake cable. The brake cable 5A connected to the brake seat 4 of the two wheels 2 is connected to the swivel 61 of a turntable 6, and can be driven by the single rotation of the turntable 61; at this time, there is another section between the brake handle 1 and the turntable 6. Brake cable 5B, its inner cable body 52B is to pass on the curved groove 611 of the swivel body 61, connect two brake handles 1 with the two ends of the same cable body, and the two brake handles 1 can be connected with the swivel body 61, either The independent pulling of brake handle 1 all can pass through rotating disc 6, and the brake cable 5A of two brake seats 4 that join is pulled and controlled braking state, also can cooperate with brake handle 1 and select two-way pulling and position.

Referring to Figures 7 and 8, when one of the brake handles 1 is pulled to pull the inner cable body 52B connected with the brake cable 5B, the inner cable body 52B that is placed in the curved groove 611 of the swivel body 61 in the turntable 6 is due to the pulled head. The section is close to the curved groove 611 and can instantly drive the swivel 61 to rotate, so that the inner cable body 52A of the brake cable 5A on the lower section of the turntable 6 is stretched, and the outer cable body 51A is the same as the above-mentioned embodiment, that is, pushes the brake seat. 4 Make the bottom tooth body 44 separate from the lower disc edge tooth surface 211 of the brake disc 21, so that the wheel 2 is in a rotatable state. Also, once the inner cable body 52B inserted in the curved groove 611 of the rotating body 61 is rotated by the rotating body 61, the rear section of the inner cable body 52B passing through the curved groove 611 is compressed, so the inner cable body 52B in the rear section pushes back The tight contact force of the cable body relative to the curved groove 611 is reduced, so that the pulled distance of the inner cable body 52B cannot completely drive the swivel body 61 and only form an appropriate interlocking transfer angle, and the swivel body 61 is driven and positioned. The rear section of the inner cable body 52B that has been squeezed returns to the degree of tightness. At this time, another brake handle 1 is pulled, as shown in Figures 9 and 10. The action form is the same as above, but the rotating body 61 of the turntable 6 is driven to rotate again, and this transfer angle causes the brake seat 4 to move down further under the push of the outer cable body 51A of the lower brake cable 5A, thereby making the The additional tooth 45 at the top abuts against the tooth surface 211 of the upper edge of the brake disc 21 downwards to brake the wheel 2 .

In addition, using the design of the present utility model, if the brake handle 1 is pulled to brake, the tooth body 44 at the bottom end of the brake seat 4 directly engages against the tooth surface 211 of the lower disc edge of the brake disc 21 and is locked, so that the wheel 2 is suddenly locked. The brake is locked. In this situation, the utility model can provide an improved solution. Referring to FIGS. The inserting shaft 241 and the end edge of the shaft hole 231 docked with the seat 23 are respectively formed with a protrusion 242 and a locking groove 232, for the joint plate 24 to be positioned in the axle seat 23 and cannot rotate relatively; an elastic element 25 is set in the axle seat 23 to Push the engagement disc 24, and the side of the engagement disc 24 opposite to the brake disc 21 forms an oblique contact surface 243, and the corresponding side of the brake disc 21 is provided with a concave surface 212, when the elastic element 25 pushes the engagement disc 24, the oblique contact surface 243 and the recessed surface 212 are stretched and matched, so that the brake disc 21 can rotate to a limited extent relative to the joint disc 24, even if the brake disc 21 is locked and locked, the wheel 2 can still rotate slightly and then stop.

In summary, the brake controller of the manpower pusher provided by the utility model utilizes the characteristics of the inner and outer cables of the brake cable and the characteristics of the turntable to realize various brake structures and methods. Compared with the conventional technology, it is more convenient to use. Not only can the brake handle be controlled at the same time, but also one of the handles can be selected to achieve the function of controlling the brake or release of the left and right wheels, so it is suitable for the elderly or walking by the car It is applicable to everyone, and the overall structure is novel and progressive.
