Detailed Description

The embodiments of the present invention will be described in detail below with reference to the above drawings.

As shown in fig. 1 to 7, the bicycle comprises a basket body 1, an underframe 11, a travelling wheel 12, a brake base 2, an extension block 21, a brake pedal 3, a brake pedal 31, a pedal spring 32, a spring hole 33, a guide hole 34, a release-stopping window 4, a brake block 41, a brake block spring 42, a guide shaft 43, a release-stopping block 44, a brake pattern 5, a brake button 6, a brake pin 61, a brake pin spring 62 and a lower inclined plane.

A basket brake device can be used as a brake component for the walking of a basket, the basket is mainly suitable for a pet basket carrying pets, and the structure of the basket is mainly composed of a basket body 1, a bottom frame 11 at the bottom of the basket body, walking wheels 12 at the bottom of the bottom frame and the like.

The brake device is arranged on the bottom frame 11 and comprises a brake base 2 fixed on the bottom frame 11, a through hole which is communicated up and down is arranged in the brake base so that the brake pedal 3 can be installed in a lifting way, namely, the lifting pedal 3 can move up and down relative to the brake base 2 in the through hole.

3 top surfaces of brake pedal 3 design for the coarse decorative pattern face in order to play pedal skid-proof effect, 3 bottoms of brake pedal are equipped with

brake block

4, 3 one sides of brake pedal are equipped with brake pin 6.

Wherein, the design structure of brake pin 6 does: a side hole is arranged in the brake seat 2, the position of the side hole is positioned on the side surface of the basket body 1, an exposed brake key 5 is arranged in the side hole, and the brake key is required to be designed to be prevented from falling off from the side hole; meanwhile, the brake pin 6 is arranged in the mounting hole at one side of the brake pedal 3 and is elastically pushed by a brake pin spring 61 in the mounting hole to move outwards; thus, in normal state, if the mounting hole and the side hole are aligned, the brake pin 6 elastically pushed by the brake pin spring 61 will move outwards and enter the side hole to form locking, i.e. locking the lifting movement of the brake pedal 3, otherwise the brake pin 6 overcomes the elastic pushing of the brake pin spring 61 and moves inwards to separate from the side hole to form unlocking, i.e. unlocking the lifting movement of the brake pedal 3.

Of course, the unlocking of the brake pin 6 is actually made by pressing the brake button 5 inward to push the brake pin 6 out of the side hole.

The end part of the brake pin 6 is provided with a lower inclined surface 62, so that the brake pin 6 can rapidly enter the side hole after touching the side hole, and the accuracy and the reliability of the braking action are improved.

In addition, a spring hole 32 extending along the axial direction and a pedal spring 31 installed in the spring hole are arranged in the brake pedal 3, and the lower end of the pedal spring is elastically pushed on the brake base 2, so that the brake pedal 3 always has a tendency of moving upwards under the elastic pushing of the pedal spring 31 in a normal state.

The spring hole 32 is a C-shaped hole, and the purpose of the C-shaped hole is to enable the extension block 21 of the brake base 2 to enter the spring hole 32 for the elastic pushing of the lower end of the pedal spring 31 without affecting the lifting movement of the brake pedal 3.

The design structure of the brake block 4 is as follows: the brake block 4 is fitted by means of a top guide shaft 42 in a guide hole 33 of the brake pedal 3, which also extends axially along the brake pedal 3, i.e. parallel to the spring hole 32, and interconnected brake block springs 41 are provided between the brake block 4 and the brake pedal 3, in particular between the guide shaft 42 and the guide hole 33, with the purpose of enabling the brake block 4 to be lifted synchronously when the brake pedal 3 is lifted.

And the brake block 4, that is, the guide shaft 42 is provided with a slip-off preventing block 43 which is fitted in the slip-off preventing window 34 on the bottom side of the brake pedal 3 for the purpose of preventing the brake block 4 from slipping off from the bottom of the brake pedal 3.

The bottom surface of the brake block 4 is provided with brake lines 44 to increase the friction force when the brake block 4 is contacted with the ground, and improve the brake force.

The working process of the utility model is as follows: when the brake pedal 3 is stepped downwards, the brake pin 6 is driven to be locked in a side hole of the brake base 2, meanwhile, the brake block 4 is synchronously pushed to descend to abut against the ground to form a brake, and the brake block spring 41 mainly aims to realize that the brake block 4 can elastically abut against the ground; when the brake pin 6 is separated from the side hole of the brake base 2 for unlocking, the brake pedal 3 is elastically pushed by the pedal spring 31 to ascend and reset, and the brake block 4 is synchronously driven to ascend and separate from the ground to form brake release.

Obviously, because the brake part directly sets up on chassis 11, the broad space also brings very big convenience for brake operation, and overall structure design is simple moreover, steps on convenient operation, especially carries out brake braking with chassis 11, compares traditional walking wheel 12 brake braking, can provide more reliable brake braking effect, uses also safer.

The above description is only a specific embodiment of the present invention, and those skilled in the art should understand that any similar structural design to the embodiment is included in the protection scope of the present invention.
