Figure 2a is the overall configuration of the cart that the fastener is attached to the bottom plate of the transport cart and the caster leg is fastened by the fixing pin to the fastener.

FIG. 2B is an enlarged view of a portion 'A' in FIG. 2A, that is, a portion in which the caster leg is fastened to the fastener by the fixing pin.

In the mounting of the caster leg according to the prior art, the caster leg shown in FIG. 1A is inserted into the fastener shown in FIG. 1B and the fixing pin is inserted into the fixing pin hole formed in the fastener to complete the mounting.

In the case of detachment of the caster leg, the process of mounting described above is reversed and detached.

However, in the above-described prior art, two or more workers have to lift the conveyed article by a forklift or the like to exactly match the fixing pin hole formed in the caster leg and the fixing pin hole formed in the fastener, and then insert the fixing pin.

In this case, it is very difficult and difficult to endure the load of the part and fit the fixing pin hole, and in this process, there is a big risk of injury to the worker or damage to the goods.

The present invention has been proposed to solve the problems of the prior art, and an object of the present invention is to provide a transport cart capable of mounting and detaching the caster legs that can be easily and stably mounted and detached caster legs.

In addition, another object of the present invention is to provide a transport cart that can be detachably mounted caster legs that one worker can safely and quickly mount and detach the caster legs to a transport cart.

As described in claim 1, the transport cart capable of long detachment of the caster leg according to the present invention for solving the above technical problem is a fastener 20 to which the caster leg 30 is coupled to four side surfaces of the bottom plate of the transport cart. In the carrying cart in which the caster leg 30 is detachably attached to the fastener 20, the caster leg 30 and the caster leg 30 to which the fixing pin 35 is integrally coupled are provided. A fastener 20 to be inserted, wherein the fastener 20 includes a hollow cylindrical insertion groove 21 into which the caster leg 30 is inserted; And a coupling part 22 formed at a lower end of the insertion groove 21 to form a fitting groove into which the fixing pin 35 is fitted in an upward direction from below.

The coupling portion, as described in claim 2, after the fixing pin 35 is fitted into the fitting groove (22a), it is characterized in that it further formed a bending groove (22b) to be rotated in one direction.

The bending groove is, as described in claim 3, characterized in that after the fixing pin 35 is inserted into the bending groove (22b) is inserted, further formed a narrow curved surface in the upper and lower to prevent separation. .

The carrying cart capable of long detachment of the caster leg according to the present invention having the above constitution has an effect of easily and stably carrying the caster leg to the carrying cart.

In addition, there is an effect that one worker can safely and quickly remove the caster leg.

The terms or words used in this specification and claims are not to be construed as limiting in their usual or dictionary meanings, and the inventors may appropriately define the concepts of terms in order to best describe their own design. It should be interpreted as meaning and concept corresponding to the technical idea of the present invention on the basis of the principle of the present invention.
