Description
The present invention relates to an automatic length variable type hand cart, and more particularly, to an automatic length variable type hand cart capable of adjusting a cargo loading space to facilitate loading of a volume, particularly a load having a large load.
In general, a cart is a means of transportation used to conveniently transport heavy or bulky items to a person.
The carts are made in various forms depending on the size and volume of the cargo to be loaded.
Particularly, hand carts, which are mainly used for moving light cargo in the room, are usually composed of a horizontal frame and a handle made of a vertical frame.
These carts mainly contain cargoes in boxes or baskets, and then move the boxes or baskets on top of the horizontal frame.
However, when the conventional cart is loaded with a bulky cargo, the cargo loading space on the horizontal frame is narrowed, and the cargo is broken on the ground, or a part of the cargo is attracted to the ground. That is, there was a problem that the cargo was damaged.
In addition, the conventional cart has a problem that it is difficult to transfer a bulky object because the loading space is narrow, and in particular, when the number of cargo to be transferred is large, it must be transported several times in a divided manner.
In addition, the conventional hand cart is mainly used in the room, and when a corner of the hand cart hits the wall, there is a problem that the building is damaged.
Accordingly, there is a need for an automatic length-variable hand truck that can selectively expand the cargo space and adjust the degree of expansion.
In order to solve the above problems, the technical object of the present invention is to provide an automatic length variable type hand cart which can easily adjust a cargo loading space.
According to an aspect of the present invention, there is provided a display device including a first frame, a second frame and a third frame provided at one end and the other end of the first frame, And a pair of actuating parts provided below the second frame and the third frame to operate the guide part, wherein the actuating part is provided at the lower part of the second frame and the third frame, Wherein the distance between the first frame and the first frame is automatically adjusted.
In one embodiment of the present invention, ribs are provided under the first frame to the third frame, and button holes are further formed in the second frame and the third frame.
In one embodiment of the present invention, the length adjuster includes a first rod inserted into both ends of the first frame and one end of the second frame and the third frame, and the first rod has a plurality of Hole units are provided.
In one embodiment of the present invention, the extending portion includes a second rod inserted into both ends of the first frame and one end of the second frame and the third frame, the second rod being formed outside the first rod, And a pressing unit which is inserted in the second rod, one end of which is fixed to the rib and the other end is fixed to one end of the spring, and the spring is inserted into the second rod And is compressed by the wall provided and the pressing unit.
According to an embodiment of the present invention, the operation unit includes a housing forming a body, a button unit extending from an upper end of the housing, the button unit having a size corresponding to the buttonhole, A protruding unit protruding upward from the guide groove, the protruding unit having a size corresponding to the hole unit, an elastic member inserted and coupled to the groove provided in the lower portion of the housing, A lid unit coupled to the lower portion of the housing, and an escape prevention unit extending upward from the lid unit and sized to be inserted into the elastic member.
According to an embodiment of the present invention, the distance between the corresponding frame and the first frame may be adjusted according to the position where the protruding unit and the hole unit are coupled to each other.
In one embodiment of the present invention, a stopper may be provided at both ends of the first rod and the second rod.
In one embodiment of the present invention, a guide rail is provided at a lower end of the first frame to the third frame, and is provided at a position corresponding to the first rod and the second rod. have.
In one embodiment of the present invention, a guide roller may be provided at both edges of the second frame and the third frame.
In one embodiment of the present invention, a sub-wheel may be further provided at the lower end of the first frame.
According to an embodiment of the present invention, the first frame, the second frame, and the third frame are separately extended in the longitudinal direction so that the space in which the cargo can be loaded can be expanded.
In addition, the automatic length variable hand cart is convenient because it is possible to adjust the distance between each frame according to the volume or transport path of the cargo.
Further, an elastic member is provided in the operation part, so that it is convenient to adjust the frame interval.
Further, the guide portion can move each of the frames in a straight line.
Further, the guide rollers are provided at both side edges of the second frame and the third frame, so that the cargo can be transferred safely. Specifically, when the edge of the automatic length adjustable hand cart hits the wall in the process of moving the cargo in the building, the guide roller can prevent the building or hand cart from being damaged by buffering action.
Further, the guide portion can strengthen the connection between the frames and support the load caused by the cargo to be evenly distributed to each frame. In addition, the guide portion constitutes the skeleton of the first frame to the third frame, so that even when a heavy load such as a bolt, a metal mold, and a machine component is loaded on each frame, each frame can be stably supported. In other words, stable cargo transportation is possible.
In addition, a spring is provided inside the rod located outside, so that the second frame and the third frame can be moved easily.
Further, a load applied to the first frame can be dispersed when a load with a large load is selectively provided on the lower portion of the first frame.
It should be understood that the effect of the present invention is not limited to the effects described above, but includes all effects that can be deduced from the detailed description of the present invention or the composition of the invention described in the claims of utility model registration claims.
