Therefore, It should be understood that various equivalents and modifications may be present.

Hereinafter, preferred embodiments of the present invention will be described in detail with reference to the accompanying drawings.

Fig. 1 is an exploded perspective view of a racetrack having an improved joining structure according to the present invention, Fig. 2 is a perspective view of the racetrack having an improved joining structure according to the present invention, and Fig. 3 is a sectional view of the racetrack having an improved joining structure.

1 to 3, a roller car 1 having an improved coupling structure according to the present invention has a roller housing 10 in which a roller 11 is extended and projected downward in the center, and a roller housing 10, A coupling piece 13 having a coupling hole 14 is formed on both sides of an upper end of the coupling piece 13,

A pressing member 100 for applying a pressing force when a bolt (not shown) is fastened to the coupling hole 14 and a coupling bolt 200 is fastened to the pressing member 100 do.

Here, the pressing member 100 is made of a synthetic resin material, and is inserted from the lower part of the coupling hole 14, and protrudes upward.

At this time, the pressing member 100 is formed with a bolt or through hole 110 through the center thereof.

The pressing member 100 has a supporting portion 120 having a diameter enlarged to be supported at the bottom of the engaging hole 14 at the bottom of the engaging hole 14 at the lower end in the process of being coupled to the engaging hole 14, And is prevented from being pierced into the upper part of the coupling hole (14) when the coupling part is engaged with the coupling hole (14) through the support part (120).

The pressing member 100 has a plurality of rows of wedge-shaped pressing protrusions 130 extending upwardly and downwardly from the outer circumference of the pressing protrusion 130 to the lower end of the pressing protrusion 130, 100 are coupled to the engaging holes 14 at the upper end of the engaging holes 14 in the process of engaging the engaging holes 14 with the engaging holes 14.

The pressing member 100 has a cutout hole 140 formed on both sides thereof so as to communicate with the bolt or the through hole 110 while being perpendicular to the outer circumference of the pressing member 100. Through the cutout hole 140, A predetermined elastic force is applied to the elastic member 130.

In the present invention, the coupling bolt 200 is fastened to the bolt or the through hole 100 from the lower portion of the pressing member 100. In this case, The coupling bolt 200 is configured to be tightly coupled with a thread bolt or a thread larger than the thread hole 100.

Hereinafter, the operation of the carriage having the improved coupling structure according to the present invention will be described in detail with reference to the accompanying drawings.

It is a matter of course that the pressing member 100 configured as described above is manufactured in a state where it is coupled to the carriage 1 at the factory in manufacturing the carriage 1. The coupling bolt 200 and the pressing member 100 in a state in which they are connected and used.

3, the pressing member 100 coupled to the carriage 1 is moved to the engaging piece 13 around the bottom surface of the engaging hole 14 through the supporting portion 120 formed at the lower end of the pressing member 100, The pressing member 100 is supported by the uppermost part of the upper part of the coupling hole 14 through the pressing protrusion 130 formed at the lower end of the coupling hole 14, And is prevented from being detached from the carriage 1 during the distribution and management process.

4, in order to engage the carriage 1 to which the pressing member 100 is coupled to the sash 20, in order to engage the carriage 1 in the normal chassis 20, The engaging hole 14 of the engaging piece 13 for fixing the engaging car 1 and the engaging hole 22 of the chassis 20 are aligned with each other, In the present invention, the pressing protrusion 130 of the pressing member 100 is protruded from the upper portion of the fitting hole 14 and is inserted into the fitting hole 22 through the pressing member 100, A predetermined shrinkage elastic force can be applied to the pressing jaw 130 by the cutting hole 140 in the process of the pressing member 100 being inserted into the fixing hole 22 at this time.

That is, by using the pressing member 100 as described above, the engaging holes 14 of the racing car 1 and the fastening holes 22 of the chassis are matched with each other by a simple operation, .

Then, the bolt of the pressing member 100 or the coupling bolt 100 fastened to the insertion hole 110 is tightened to completely engage the knocker 1. At this time, as shown in FIG. 5, The pressing member 100 is opened by the entry of the coupling bolt 200 while the pressing member 100 is in a state of being resiliently moved through the cutting hole 140 And the pressurizing protrusion 130 formed on the outer circumference presses the inner circumferential surface of the fastening hole 22 of the sash 20 so that the pressurization support can be firmly performed without a gap with the fastening bolt 200.

That is, in the present invention, the pressing force is applied to the pressing member 100 during the fastening process of the coupling bolt 200 as described above, and the fastening hole 22 of the sash 20 is press- So that stable coupling can be achieved.

Further, since the coupling bolt 200 for coupling the carriage 1 is formed to be coupled, the material management becomes very easy.

As described above, according to the present invention, it is possible to accurately and conveniently secure the joint position due to the assembling of the race car in the process of coupling the race car to the chassis, and the pressing force of the pressing member Tight tightening force can be imparted by acting on the inner circumferential surface of the fastening hole of the sash.
