In order to achieve the above objectives, the technical solution of the utility model is as follows：
The braking mechanism of dining car, be mounted on dining car chassis section bar on, mainly by be arranged on chassis castor, brake
Two groups of brake assemblies that are foot-operated, being located at dining car front and back end respectively and rectangular connector composition；The top tool of the castor
There is a castor gasket being fixed on the chassis, there are one circular holes for tool in the castor gasket；The brake assemblies by brake lever,
Piece and membranous disc composition are carved in brake, and the brake is carved piece and is located in the circular hole, and bottom is connect with the column of the castor；It is described
One end of brake lever is connect with the membranous disc, and the other end is pressed in described brake and carves the top of piece, and described brake carves the top tool of piece
There is an inclined surface, the brake lever is provided with and the inclined surface is matched tiltedly carves；The connector connects two groups of brake assemblies
Integrally, the connector is movably hinged by four connecting rod head and the tail, wherein short connecting rod is rotatably coupled to institute
It states on membranous disc, long connecting rod and the foot-operated connection of the brake.
Further, have the scotch that outwardly protrudes on the hole wall of the circular hole, the brake carve on piece setting with
The matched locking groove of scotch.
Further, having a hole in the brake lever, there is cylinder on the membranous disc, the cylinder is inserted in the item
The brake lever is connect with the membranous disc in hole.
The use principle of the utility model is：When step on one of brake it is foot-operated when, brake is foot-operated to push long connect backward
Extension bar, long connecting rod driving membranous disc rotation, brake lever are moved to both sides, and brake is carved piece and is pressed on the column of castor downwards, makes
Dynamic castor, forms brake；When cancelling braking, brake just now is ridden and is lifted, and step on another brake and ride, the brake foot
It steps on and pushes another root long connecting rod backward, long connecting rod driving membranous disc rotates backward, and brake lever is pressed in brake and carves piece to contract
On strength disappear, brake carve piece unclamp castor, brake release.
The beneficial effects of the utility model are：Braking mechanism has two groups of brake assemblies, by this two groups of brake groups during use
Part is separately positioned on the front and back end of dining car, steps on and is braked while brake is foot-operated can to realize four castors, braking quality is good.

Specific embodiment
The following is a combination of the drawings in the embodiments of the present utility model, and the technical scheme in the embodiment of the utility model is carried out
Clearly and completely describe.
Embodiment one
The attached drawing of the present embodiment is referring to Fig. 1-5.
The braking mechanism of dining car, be mounted on dining car chassis section bar 1 on, mainly by be arranged on chassis castor, stop
Vehicle is ridden 2, is formed respectively positioned at two groups of brake assemblies of dining car front and back end and rectangular connector 4；The top tool of castor
There is a castor gasket 5 being fixed on chassis, there are one circular hole 5a for tool in castor gasket；Brake assemblies carve piece by brake lever 6, brake
7 and membranous disc 8 form, brake is carved piece and is located in circular hole 5a, and the column of bottom and castor connects；One end of brake lever connects with membranous disc
It connects, the other end is pressed in the top that piece is carved in brake, and the top that piece is carved in brake has inclined surface 7a, and brake lever is provided with and inclined surface
That matches tiltedly carves 6a；Connector links into an integrated entity two groups of brake assemblies, and connector is movably hinged by four connecting rod head and the tail,
Wherein short connecting rod 4a is rotatably coupled on membranous disc, long connecting rod 4b and the foot-operated connection of brake.
Step on one of brake it is foot-operated when, brake is foot-operated to push long connecting rod backward, long connecting rod driving membranous disc rotation,
Brake lever is moved to both sides, and brake is carved piece and is pressed on the column of castor downwards, while brakes four castors, forms brake；It takes
Disappear braking when, brake just now is ridden and is lifted, and steps on that another brake is foot-operated, which rides pushes another root long backward
Connecting rod, long connecting rod driving membranous disc rotate backward, and brake lever is pressed in the strength disappearance that on piece is carved in brake, brake to contract
It carves piece and unclamps castor, brake release.
There is the scotch 5b outwardly protruded, on piece setting and the matched stop of scotch are carved in brake on the hole wall of circular hole 5a
Slot 7b, scotch and locking groove cooperation can prevent brake from carving piece and rotated in the circular hole of castor gasket.
Connector can be changing into parallelogram from rectangle, during variation, between two root long connecting rods
Distance can also change, in order to eliminate the influence that the variation is brought, so designing a hole 6b, the cylinder of membranous disc in brake lever
8a is inserted in a hole and connect brake lever with membranous disc.
Embodiment two
Braking mechanism in embodiment one only has one group of brake to ride 2, when dining car is longer, can increase by one in opposite side
Group brake foot-operated 2 '（Referring to Fig. 6）.
A variety of modifications of these embodiments will be apparent for those skilled in the art, herein
Defined General Principle can be real in other embodiments without departing from the spirit or scope of the present utility model
It is existing.Therefore, the utility model is not intended to be limited to the embodiments shown herein, and be to fit to it is disclosed herein
Principle and the consistent most wide range of features of novelty.
