Abstract
More particularly, the present invention relates to a carriage which is capable of quickly and easily fastening a bolt to a coupling hole formed in a sash through a pressing member, The present invention also relates to a railcar having an improved coupling structure for applying a pressing force in a coupling hole of a sash when a bolt is fastened so as to provide a firmer fastening force.
Description
BACKGROUND OF THE
Generally, a trolley is a small iron wheel that slits and fits a groove under the sash (frame) of a door and a window so that the sliding door can be closed well, and has a rolling function.
On the other hand, such a car was also proposed in the Utility Model Registration Application No. 20-1997-0035539 and the Patent Application No. 10-2012-0014018.
That is, in such a general carriage, first, a roller housing protruding downward from the intermediate portion is formed, while a roller housing having a protruding portion formed upward is formed.
The roller housing is formed with engaging pieces formed with protruding and engaging holes horizontally on both sides of the upper portion thereof.
That is, in order to engage the above-mentioned car with the chassis, a coupling hole is formed in the lower part of the chassis so as to be in communication with the coupling hole of the car to engage with the car, and the bolt is inserted through the coupling hole, And fastened to the fastening hole.
However, when the size of the coupling hole and the size of the coupling hole are not matched, an auxiliary member such as a separate knock block or the like may be inserted into the coupling hole of the chassis, There has been an inconvenience in the operation such as the bolting work being performed in the state of being installed in the ball.
SUMMARY OF THE INVENTION The present invention has been devised in order to solve the above problems, and it is an object of the present invention to provide a fastening member for fastening a fastening member to a fastening member, The object of the present invention is to provide a railcar having an improved coupling structure for enabling a bolt to be fastened and a pressing force to be given in a coupling hole of a sash when a bolt is fastened so as to provide a stronger fastening force.
In order to attain the above object, there is provided a roller car having a roller housing in which a roller is axially projected and projected downward, and a coupling piece having a coupling hole (14) is formed on both sides of an upper end of the roller housing,
A pressing member coupled to the engaging hole and integrally formed with the engaging hole; And
And a coupling bolt inserted from a lower portion of the pressing member,
delete
The pressing member
And a support portion supported by the engagement piece around a bottom surface of the engagement hole is formed at a lower end of the support hole, and a peripheral portion of the support hole is gradually extended from the lower end to the lower end of the engagement hole, A wedge-shaped pressurizing stool is formed in a plurality of rows and a plurality of rows are formed in a top and a bottom, and a vertical hole is formed in the periphery, and a cutting hole is formed on both sides so as to communicate with the bolt and the bored hole, Is formed in a shape supported by the upper periphery,
Characterized in that the coupling bolt is forced from a lower portion of the pressing member to a bolt or a through hole.
As described above, according to the present invention, in the carriage having the improved coupling structure, the pressing member protruding upwardly is inserted into the coupling hole formed in the coupling piece, and when the coupling is engaged, So that it is possible to obtain a quick and convenient coupling effect when combining the wheels.
In addition, when the bolt is fastened to the pressing member, the pressing member presses the inner circumferential surface of the engaging hole of the sash, so that tight coupling can be achieved without a clearance.
