Abstract

The utility model relates to a trailer brake device of a bicycle, which comprises a front U-shaped iron sheet and a rear U-shaped iron sheet fixed to the connecting tube of a bicycle frame. The interiors of the front and rear U-shaped iron sheets are respectively equipped with front and rear rubber blocks. A T-shaped brake iron support is inserted in the rubber blocks. The non-T-shaped end of the T-shaped brake iron support is connected with a foot-operated member via a connecting iron sheet. The foot-operated member is rotatably connected with a fixed iron sheet. A brake disc is arranged on the wheel shaft of the bicycle. The brake disc is matched with the T-shaped end of the T-shaped brake iron support. The bicycle trailer is equipped with two brake devices and the two brake devices are arranged beside the wheels of the bicycle trailer. The brake device is simple in structure. By adopting the brake device, the bicycle trailer can be prevented from blowing away by wind on a slope or during the parking process, so that the injuries to pets or children are prevented. During the parking process, the movement of the bicycle trailer can be prevented by the brake device when some emergencies appear suddenly.

Description

The trailers brake gear

Technical field

The utility model relates to a kind of brake gear, especially relates to a kind of brake gear that is used to take advantage of the trailers that carries pet or child.

Background technology

In countries such as America and Europes by bike not only as running vehicle, the important utensil of amusement and recreation and motion especially, wherein trailer is installed in behind the bicycle it, all the fashion especially in recent years, trailers can be used for manned or pet.But existing trailers majority is the fixing device of usefulness not, occurs because wind is big or be positioned on the slope through regular meeting, and trailers moves voluntarily, can cause the injured and scaring of pet or children, and is very dangerous.

Summary of the invention

The utility model technical matters to be solved provides a kind of brake gear that is used on the trailers, handled easily, and can avoid bicycle to move voluntarily.

The technical scheme that its technical matters of the utility model solution is taked is: a kind of trailers brake gear; Comprise the preceding U sections sheet and back U sections sheet that are fixed on the vehicle frame connection pipe; Rubber block and back rubber block before their inside is respectively equipped with; T type brake iron props up and interts in rubber block, and an end of the non-T type that T type brake iron props up is connected with foot piece through connecting iron plate, and foot piece is rotaryed connection with fixed iron piece; Brake disc is installed on axletree, and brake disc cooperates with the T type end that T type brake iron props up.

Two wheels can brake for ease, and described brake gear has two, are positioned at by the trailers wheel.

The beneficial effect of the utility model is: simple in structure; Can obviously avoid trailers to be positioned on the slope or when stopping is run by wind; Cause the injured problem of pet or children, when stopping, tend to run into emergency situation, need prevent its action by a device this moment.

Fig. 2 is the structural representation in releasing when brake of the utility model;

Structural representation when Fig. 3 is the utility model entrucking;

Fig. 4 is the partial enlarged drawing at A place among Fig. 3.

Among the figure: 1, preceding U sections sheet 2, back U sections sheet 3, foot piece 4, connect that iron plate 5, back rubber block 6, T type brake iron prop up 7, preceding rubber block 8, brake disc 9, vehicle frame connection pipe 10, fixed iron piece

The specific embodiment

Like Fig. 1, Fig. 2 and a kind of trailers brake gear shown in Figure 4; Comprise the preceding U sections sheet 1 and back U sections sheet 2 that are fixed on the vehicle frame connection pipe 9, rubber block 7 and back rubber block 5 before their inside is respectively equipped with, T type brake iron props up 6 and interts in rubber block; The end that T type brake iron props up 6 non-T type is connected with foot piece 3 through connecting iron plate 4; Foot piece 3 is rotaryed connection with fixed iron piece 10, and brake disc 8 is installed on axletree, and brake disc 8 and the T type iron that brakes props up 6 T type end and cooperates; Described brake gear has two, is positioned at trailers wheel other (as shown in Figure 3).

Like Fig. 1 is braking state, and foot piece 3 is stepped on, and foot piece 3 rotates on fixed iron piece 10, and drive connects iron plate 4, connects iron plate 4 drive T types brake iron and props up in the 6 insertion brake discs 8, accomplishes brake, otherwise then accomplishes un-brake action (as shown in Figure 2).

The trailers that has brake gear like this; Convenient on the slope or the big place of wind stop; The carelessness that overcomes simultaneously because of taking care of personnel makes the danger that car moves voluntarily and brings under the situation of not keeping an eye on children, at the left and right wheels of car brake gear is installed all, steps on the effect that the next one can reach brake; Greatly reduce the problem that to brake because brake damages, and can obviously increase trailers stability and safety in use.
