Description

A kind of trailers synchronous brake brake equipment
Technical field
The present invention relates to braking device, particularly a kind of trailers synchronous brake brake equipment.
Background technology
In countries such as America and Europes, bicycle is not only used as running vehicle, the important utensil of amusement and recreation and motion especially.Wherein trailer uses after being arranged on bicycle, all the fashion especially in recent years.Trailers can be used for manned or pet.And common braking device can not meet the effect that trailers travels synchronous brake braking, and bicycle is when emergency brake is braked, trailers can be made to have force of inertia forward, there is inertia insecurity accident, during bicycle descending, also trailers likely can be made to occur rollover, make the children taking trailer injured.
Summary of the invention
For solving the problems of the technologies described above, the object of the present invention is to provide a kind of trailers synchronous brake brake equipment, sudden stop in use can be avoided to cause children injured, make traveling stability and safety more.
For realizing above-mentioned technical purpose, reach above-mentioned technique effect, the present invention is achieved through the following technical solutions: a kind of trailers synchronous brake brake equipment, comprise drawbar, brake assembly set and brake, brake assembly set comprises U-type groove connecting element, U-type groove plastic parts, brake sleeve pipe, brake screw rod, end plug and stage clip, U-type groove connecting element is welded in trailer chassis, described U-type groove plastic parts is installed in described U-type groove connecting element, stage clip, sleeve pipe is end to end successively is from the inside to the outside installed in the U-type groove of described U-type groove plastic parts for end plug and brake, the left and right sides cell wall of U-type groove connecting element and the left and right sides cell wall of U-type groove plastic parts all have pilot hole, described brake screw rod is plugged in together with brake sleeve pipe, and the two ends of brake screw rod are all inserted in the pilot hole of the pilot hole of the cell wall of described U-type groove connecting element and the cell wall of U-type groove plastic parts, described brake sleeve pipe is connected with described drawbar again, the two ends of described brake screw rod are respectively connected with brake by brake cable.
Further, the left and right sides of described trailer chassis is welded with attaching parts respectively, and described brake is fixed on described attaching parts.
Further, the tip inside of described U-type groove plastic parts is provided with draw-in groove, and the end of described stage clip is loaded in this draw-in groove.
The invention has the beneficial effects as follows: structure of the present invention is simple, when bicycle emergency brake is braked, bicycle can make drawbar drive brake sleeve pipe and brake screw rod to the power of drawbar, and then drive brake cable, thus brake is braked wheel, realize bicycle and the braking of trailers synchronous brake, emergency braking is in use avoided to cause children injured, and obviously can increase trailers braking effect in the process of moving, make traveling stability and safety more, it also avoid the human discomfort that trailers brings to human body because of drag, and the danger that occurs that trailers is turned on one's side also can be avoided when bicycle descending.

Detailed description of the invention
Below in conjunction with accompanying drawing, preferred embodiment of the present invention is described in detail, can be easier to make advantages and features of the invention be readily appreciated by one skilled in the art, thus more explicit defining is made to protection scope of the present invention.
As shown in Figures 1 to 5, a kind of trailers synchronous brake brake equipment, comprise drawbar 1, brake assembly set 2 and brake 3, wherein, brake assembly set 2 comprises U-type groove connecting element 21, U-type groove plastic parts 22, brake sleeve pipe 23, brake screw rod 24, end plug 25 and stage clip 26, U-type groove connecting element 21 is welded on the lower right side of trailer chassis 6, U-type groove plastic parts 22 is installed in the U-type groove of U-type groove connecting element 21, stage clip 26, sleeve pipe 23 is end to end successively is from the inside to the outside installed in the U-type groove of U-type groove plastic parts 22 for end plug 25 and brake, the left and right sides cell wall of U-type groove connecting element 21 and the left and right sides cell wall of U-type groove plastic parts 22 all have pilot hole 5, brake screw rod 24 is plugged in together with brake sleeve pipe 23, and the left end of brake screw rod 24 is inserted in the pilot hole 5 of the pilot hole 5 of the left side cell wall of U-type groove connecting element 21 and the left side cell wall of U-type groove plastic parts 22, the right-hand member of brake screw rod 24 is inserted in the pilot hole 5 of cell wall on the right side of the pilot hole 5 of cell wall on the right side of U-type groove connecting element 21 and U-type groove plastic parts 22, the two ends of brake screw rod 24 can be moved in the pilot hole 5 of the pilot hole 5 of U-type groove connecting element 21 and U-type groove plastic parts 22.Brake sleeve pipe 23 is connected with drawbar 1 again, and the two ends of brake screw rod 24 are respectively connected with brake 3 by brake cable 4.
As shown in Figure 3 and Figure 4, the left and right sides of trailer chassis 6 is welded with attaching parts 7 respectively, and the brake 3 on the left of trailer chassis 6 is fixed on the attaching parts 7 in left side, and the brake 3 on the right side of trailer chassis 6 is fixed on the attaching parts 7 on right side.These two brakes 3 be connected with brake screw rod 24 carry out drag to two wheels 10,11 of trailers both sides respectively.
In addition, the tip inside of U-type groove plastic parts 22 is provided with draw-in groove 8, and when mounted, the end of stage clip 26 is loaded in this draw-in groove 8 for stage clip 26 and U-type groove plastic parts 22.
The outside of the left and right sides cell wall of U-type groove connecting element 21 is respectively equipped with a flange 9, and flange 9 is provided with a through hole, and brake cable 4 can pass this through hole when connecting brake screw rod 24 and brake 3.
Normally travel at trailers, when running into emergency brake braking, bicycle can give drawbar 1 one power backward, then drawbar 1 drives connected brake sleeve pipe 23, brake screw rod 24 is moved, thus drives two wheels 10,11 of brake 23 pairs of trailerses to carry out drag by brake cable 4, thus reach bicycle and the braking of trailers synchronous brake, make to avoid when emergency braking trailers to turn on one's side dangerous, reach the object of safety traffic.After drag completes, stage clip 26 can to rebound brake sleeve pipe 23, brake screw rod 24 and drawbar 1 to initial point, easily travels after making trailer brake.
