Description

Brake controller for human cart

The utility model relates to a brake controller, in particular to a brake controller used in manpower carts.

By the way, the use of manpower carts is quite common, such as general strollers, shopping carts, special carts for medical equipment, and various carts for the elderly or handicapped to walk, mainly as walking aids. effect. This type of manpower cart is equipped with a brake handle at the handle, and the various moving states of the movement, walking and parking of the cart are controlled by the brake device.

The brake device of the common manpower cart, in the design of controlling the synchronous braking of the left and right wheels, mainly brakes the wheel body in the form that the brake lever extending integrally relative to the left and right wheels touches or locks, and cooperates with the connecting rod. The brake handle of the type controls the action of the brake lever; or, the left and right brake handles are independently connected to the handlebars, and respectively connected to each other. A brake cable is connected to the two independent brake devices of the left and right wheels to achieve The left and right hands respectively control the braking effect of the left and right wheels.

Since the left and right brake handles are operated independently to control the left and right wheel brake devices, it is not suitable for users who are inconvenient to apply force with one hand. If any operation of the left and right brake handles can be used to simultaneously control the left and right The wheel and brake devices work together for better convenience.

The purpose of this utility model is to provide a user who is inconvenient to apply force with one hand. If any operation of the left and right brake handles can synchronously control the left and right wheel brake devices to act together, it will be easy to operate and flexible to use. the goal of.

The technical scheme of the utility model is: a brake controller for a manpower cart, which mainly includes left and right brake handles, left and right wheel brake devices and brake controllers, and is characterized in that: The upper brake cable and the other two lower brake cables connected to the left and right wheel brake devices are respectively connected to a controller, wherein: the controller is equipped with a movable turntable inside a seat, and the turntable forms a curved groove in the radial direction , and the two ends corresponding to the crossing radial direction are provided with buttonholes, and the two ends on both sides of the seat body are provided with slot holes, and a cover plate is used to cover and assemble; the upper section of the brake cable connected to the left and right brake handles The two outer cable bodies are fixedly connected in the two slot holes on both sides of the controller seat body, and the same inner cable body connected to it is stretched in the curved groove of the turntable; and the left and right wheel brakes will be connected The two lower brake cables of the device are fixedly connected in the other two slot holes on both sides of the base with its two outer cable bodies, and the two inner cable bodies are extended and fastened in the button holes at the radially corresponding two ends of the turntable.

Now further illustrate by following accompanying drawing and embodiment:

Fig. 1 is a schematic diagram of setting of the utility model with a walker.

Fig. 2 is a schematic diagram of the connection state of the utility model with the braking device.

Fig. 3, is the structural representation of the utility model.

Fig. 4 is a schematic view (1) of the action of the turntable of the present invention.

Fig. 5 is a schematic view (two) of the action of the turntable of the present invention.

Referring to Fig. 1, 2, brake controller of the present utility model mainly comprises left and right brake handle 1,2 and left and right wheel brake device 4,5 and brake controller 8 to form, wherein and left and right brake handle 1, 2 connected upper segment brake cables 3 and another two lower segment brake cables 6,7 connected with the left and right wheel brakes 4,5 are respectively connected to a controller 8.

Referring to Fig. 3, the controller 8 is provided with a movable turntable 82 in the base body 81, the turntable 82 radially forms a curved groove 821, and the two ends corresponding to the crossing radial direction are provided with buttonholes 822, and on both sides of the base body 81 Four slot holes 811 are provided at the two ends of the side, and a cover plate 83 is used to cover the seat body 81 with a tenon structure to form a solid body.

Above-mentioned upper segment brake cable 3 that links to each other with left and right brake handle 1,2 is fixedly connected in two slot holes 811 obliquely opposite to both sides of controller 8 seat body 81 with its two outer cable bodies 31, and outer cable body 31 The connected and same inner cable body 32 then penetrates and extends in the curved groove 821 of the turntable 82 to form an appropriate tight-resisting and fastening effect.

Two lower section brake cables 6,7 connecting the left and right wheel braking devices 4,5 are affixed in the other two slot holes 811 obliquely opposite to the above-mentioned seat body 81 both sides with its two outer cable bodies 61,71, and the outer The cable bodies 61 , 71 are connected, and the same inner cable bodies 62 , 72 are further extended and fastened in the buttonholes 822 at the radially corresponding ends of the turntable 82 .

Referring to Fig. 4, by the above-mentioned design, when the left and right brake handles 1 and 2 are selected and pulled separately, the same inner cable body 32 connected with the upper brake cable 3 drives the turntable 82 to rotate moderately, so that the connection The inner cable bodies 62,72 of the two lower sections of the brake cables 6,7 of the left and right wheel brake devices 4,5 are driven and stretched by the unidirectional rotation of the rotating disk 82, and the stretched inner cable bodies 62,72 cooperate with each other. Its outer cable body 61,71 just can control the action of left and right wheel brake device 4,5 and implements the action of stopping or unlocking.

In addition, the controller 8 of the present invention, in addition to adopting the form of a single brake handle to select one operation, makes the controller 8 synchronously control the left and right wheel brake devices 4, 5 to implement the rotation angle; Once the inner cable body 32 of the curved groove 821 of the turntable 82 is rotated by the turntable 82, the rear section of the inner cable body 32 passing through the curved groove 821 is squeezed, so that the inner cable body 32 is pressed against the curved groove 821 instead. decrease, so that the pulled distance of the inner cable body 32 does not completely drive the rotating disk 82 to rotate relative to each other, but only forms an appropriate linkage transfer angle (this angle can drive the braking device).

Referring to Fig. 5, when the turntable 82 is driven and fixed, the rear part of the compressed inner cable body 32 recovers the tight resistance force, and when another brake handle is pulled over time, the original inner cable body connected to this brake handle 32. The rear section becomes a pulling starting end, and its action form is consistent with the above, so that the turntable 82 is driven to rotate the second angle to drive the brake device. Therefore, the controller 8 of the present invention has a two-stage type during use. The brake device with action function is flexible to use.

In summary, the utility model can indeed select one of the left and right brake handles to operate and drive the brake devices of the left and right wheels through the controller for synchronous action. It is suitable for users who are inconvenient to apply force with one hand. To achieve the purpose of convenient operation and flexible use.
