Detailed Description

The following description is presented to disclose the invention so as to enable any person skilled in the art to practice the invention. The preferred embodiments in the following description are given by way of example only, and other obvious variations will occur to those skilled in the art. The basic principles of the invention, as defined in the following description, may be applied to other embodiments, variations, modifications, equivalents and other technical solutions without departing from the spirit and scope of the invention.

The utility model discloses a novel brake truckle combines preferred embodiment below, makes further description to utility model's embodiment.

In the embodiments of the present invention, those skilled in the art will note that the bracket, caster, etc. of the present invention can be regarded as the prior art.

Preferred embodiments.

The utility model discloses a novel brake truckle, including dull and stereotyped 10, go up pearl ware (not shown), steel ball (not shown), lower pearl ware (not shown), support 20 (the design of support rear end is longer, has the preceding punching a hole and straight notch), truckle 30 on the support, go up the pearl ware with the both sides of pearl ware all are equipped with accommodation space down, are equipped with in the accommodation space the steel ball, the steel ball rolls in accommodation space and drives go up the pearl ware with the activity of interval is followed to the pearl ware down, still includes:

a brake switch 40 (provided with switch characters and arrow prompts) and a roller 50, wherein the brake switch 40 and the roller 50 are both positioned above the caster 30, the brake switch 40 comprises a first component 41 and a second component 42, the first component 41 is positioned above the second component 42 and is integrally formed with the second component 42, the first component 41 is provided with a first notch 43, and the roller 50 is installed on the brake switch 40 by being placed in the first notch 53;

a brake pedal 60 including a third member 61 and a fourth member 62, the third member 61 being located above the fourth member 62 and being integrally formed with the fourth member 62, the third member 62 being provided with a second notch 63;

the spring plate 70 (designed to be a predetermined shape in cooperation with the brake switch 40) comprises a fifth component 71 and a sixth component 72, and the fifth component 71 and the sixth component 72 are integrally formed.

Specifically, the first member 41 has a flat plate shape, and the second member 42 has a penetrating cylindrical shape and is provided with a first through hole 44 therein.

More specifically, the third assembly 61 is shaped like a flat plate, and the fourth assembly 62 is provided with a second through hole 64 and a third through hole 65.

Further, the lower half portion of the fifth component 71 is toothed, the upper half portion of the fifth component 71 is provided with a fourth through hole 73, the sixth component 72 is flat-plate-tilted, and the sixth component 72 is provided with a fifth through hole 74.

Further, the brake switch 40 and the roller 50 are both located above the fifth member 71.

The working principle is as follows: first, the second through hole 64 of the brake pedal 60 is concentric with the fourth through hole 73 of the spring plate 70 and the first shaft 21 is inserted through the second through hole 64 and the fourth through hole 73 and riveted;

secondly, the roller 50, the brake switch 40 and the brake pedal 60 are sequentially prevented from being at predetermined positions such that the center hole of the roller 50, the first through hole 44 of the brake switch 40 and the third through hole 65 of the brake pedal 60 are concentric, and the second shaft 22 is installed to pass therethrough;

finally, the fifth through hole 74 of the spring plate 70 is concentric with the front shaft hole of the bracket 20, the third shaft 23 is installed through the hole, the second shaft 22 is riveted with the third shaft 23, and the caster 30 is riveted with the bracket 20.

A braking state: the brake pedal 60 is stepped downwards, the second shaft 22 moves backwards along the straight slot on the bracket 20 to drive the brake pedal 60 to do circular motion, the brake switch 40 makes linear motion, the roller 50 is contacted with the lower wall of the bracket 20 and rotates around the second shaft 22 to reduce the friction force between the brake switch 40 and the bracket 20 and help the brake switch 40 to do linear motion, so that the stepping on the brake pedal 60 is easier, the brake switch 40 has a smaller gap with the bracket 20 but the gap is not enough to enable the brake switch 40 to do excessive circular motion, so as to ensure the parallelism between the brake switch 40 and the bracket 20, so that the brake switch 40 works normally, the brake pedal 60 presses the first shaft 21 to drive the elastic sheet 70, the elastic sheet makes circular motion around the third shaft 23, when the second shaft 22 moves to a designated position at the rear part of the straight slot, the tilting part at the rear part of the elastic sheet 70 brakes the caster 30, the teeth at the, the caster 30 is dead-locked.

And (3) active state: if the active state needs to be recovered, the brake switch 40 is stepped forward to drive all the parts to form a chain reaction and return to the original position, and the brake of the caster 30 is released.

It is worth mentioning that the technical features such as the bracket and the caster related to the utility model can be regarded as the prior art, and the specific structure, the working principle of the technical features and the control mode and the space arrangement mode which may be related to can be selected by the conventional methods in the field, and the technical features should not be regarded as the invention point of the utility model, and the detailed description is not further specifically developed.

It will be apparent to those skilled in the art that modifications and variations can be made in the above-described embodiments, or some features of the invention may be substituted or omitted, and any modification, substitution, or improvement made within the spirit and principle of the present invention shall fall within the protection scope of the present invention.
