Description

Castor has the cart of brake structure

Technical field

The utility model relates to cart technical fields, refer in particular to a kind of cart of the castor with brake structure.

Background technique

For the ease of push object, castor can be equipped with below common cart.In object moving process, in order to adapt to not With road conditions and emergency, often need to realize the brake of castor using brake structure；And by releasing brake, object can be convenient for It continues to move to.But due to the brake structure of the castor of existing cart is complex, installation it is relatively complicated, cause its cost of manufacture compared with Height, and the brake structure of the castor of existing cart is all dead castor of directly stopping, castor is not able to rotate, so that castor and ground be made to produce Raw biggish friction, wears castor, shortens the service life of castor.

In view of this, the designer of the utility model is perfect for not attaining in the brake structure design of the castor of existing cart Caused many missings and inconvenience, and deeply conceive, and actively research improvement has a fling at and develops and design the utility model.

Utility model content

The purpose of this utility model is to provide the carts that a kind of castor has brake structure, have structure simple and extend The characteristics of service life of castor.

To achieve the above object, the solution of the utility model is:

A kind of castor has the cart of brake structure, comprising: a push bracket, at least a castor and at least one corresponding castor setting Brake structure；The lower section of the push bracket is rotationally installed at least one trundle bracket assembled for castor；The brake knot Structure includes a brake cable, a spring, a brake block and an oblique interlock plate, and the oblique interlock plate is fixed on castor branch turnablely Frame, for the oblique interlock plate between trundle bracket and castor, described brake cable one end is force side, the brake cable other end With the fixed gearing in oblique interlock plate rear end, the brake block, which is fixedly arranged on, tiltedly interlocks front edge of board, and the brake block is located at the top of castor, The spring pocket is set to brake cable, and the spring is between oblique interlock plate rear end and trundle bracket.

The push bracket includes two side levers being spaced apart and a bottom bar, and the both ends of the bottom bar, which are separately connected, is fixed on two sides The bottom of bar.

The quantity of the brake structure, castor and trundle bracket is two, and the trundle bracket is rotationally fixed respectively In the lower section of side lever, the brake cable is set in side lever, and the both ends of protruding side bar are distinguished at the both ends of the brake cable.

One is installed with above the trundle bracket to be arranged in rotation in the rotating member rotated in side lever, the brake cable In part.

A L-type hand push frame is installed between the top of the side lever of the push bracket.

The L-type hand push frame is installed with a braking hand cradle that can be overturn with respect to L-type hand push frame, and described brake cable one end is fixed In in braking hand cradle.

At least a connection piece is installed on the side lever.

The oblique sliding slot for interlocking front edge of board and having one for brake block assembly, the oblique interlock plate is in the front of sliding slot position It sets and is equipped with a bolt.

After adopting the above scheme, the utility model is designed by the structure of push bracket, castor and brake structure, the brake knot The oblique interlock plate of structure is fixed on trundle bracket turnablely, and the trundle bracket is rotationally installed in below push bracket and for castor Assembly, for the oblique interlock plate between trundle bracket and castor, described brake cable one end is force side, and the brake cable is another End and the fixed gearing in oblique interlock plate rear end, the brake block, which is fixedly arranged on, tiltedly interlocks front edge of board, and the brake block is located at the upper of castor Side, the spring pocket are set to brake cable, and the spring is between oblique interlock plate rear end and trundle bracket, thus when needing to this When the cart brake of utility model, user only needs to apply pulling force in the force side of brake cable, has been pulled upwardly brake cable, presses Contracting spring simultaneously makes oblique interlock plate rear end be upturned, so that pushing the brake block for tiltedly interlocking front edge of board applies resistance in castor, Make castor that can not advance in rotation forward, to have the function that brake, overall structure is simple, and the utility model is in addition to can be with Castor is stopped dead, when carrying out slowing-down brake, castor can also continue to rotate, and castor and ground will not be made to generate wear friction, Therefore either emergency brake or deceleration will not damage the surface of castor, can extend the service life of castor.
