Abstract

The present invention relates to a cart for transporting goods facilitating an assembly work by changing structures of cart shelves for coupling finishing caps and post rods. To achieve the same, the cart for transporting goods wherein the multiple cart shelves (100) supported by the post rods (110) in a form of multiple layers and movable wheels (130) are installed in the lower part includes the finishing caps (120) for preventing through-holes (101) from being exposed to the outside to be coupled to the top shelf (100) while the through-holes (101) for coupling the post rods (110) are formed in corner units of each shelf (100). A female screw unit (121) to be screwed with a male screw unit (111), which is formed in the upper part of the post rod, is formed in the finishing cap (120). Rotation preventing protrusions (122) protrude from the circumference of the lower part of the finishing cap (120) at constant intervals. A locking protrusion (102) to limit a rise of the post rod (110) is formed in an inner wall surface of the shelf through-hole (101). A protrusion guide groove (103) is formed in the locking protrusion to enable the insertion of the rotation preventing protrusion (122).

Description

{CART STRUCTURE FOR GOODS TRANSPORT}

BACKGROUND OF THE INVENTION 1. Field of the Invention [0001] The present invention relates to a cart for transporting goods, and more particularly to a cart for use in safely and easily transporting articles in hospitals and restaurants.

In general, a cart for transporting goods is called a so-called cart, which is equipped with a wheel at the bottom for easy mobility even when various articles are placed on it.

In particular, in a hospital or restaurant, a cart of the type shown in Fig. 1 is used for safe movement of articles.

As shown in the drawings, the cart in the prior art is provided with a handle 11 on one side of the main body 10 and is divided into several layers of shelves 12. On the lower side of the main body 10, Respectively.

Such a cart is easily used to use the articles while moving the cart to a required position with the necessary items on each shelf 12 forming a plurality of layers.

Meanwhile, in the conventional cart, the components are assembled in a state in which the components are molded from a synthetic resin material. In order to support the shelves 12 at a predetermined height, the support rods are connected to the four corners.

However, since the shelves forming the respective layers are fastened to each other through the through-holes of the support rods, the shelf positioned at the uppermost end has a different structure from that of the middle and lower plates, To this end, there has been a problem in that a mold for molding a top shelf needs to be used separately.

In addition, when the finishing cap and the support rod are fastened together, the coupling force between the support rod and the uppermost shelf is reduced, or the work efficiency is lowered due to inconvenience of assembling the support cap and the support rod due to the grooves formed in the uppermost shelf.

The present invention has been proposed in order to solve the problems of the prior art described above, and it is an object of the present invention to provide a shelf finishing apparatus and a shelf finishing apparatus, The goal is to reduce production costs.

Further, it is an object of the present invention to facilitate the assembly of the finishing cap and the support rod in the shelf located at the uppermost end of the cart, thereby improving the work efficiency.

According to an aspect of the present invention, there is provided a cart for carrying articles, in which a plurality of shelves are supported by a support bar in the form of a multi-layered structure, and a moving wheel is provided at a lower portion thereof, and through holes are formed in corners of the shelves, And a finishing cap for preventing exposure of the through hole to the outside is fastened to the shelf provided at the uppermost stage; The finishing cap is provided with a male screw portion formed on the upper end of the support rod and a female screw portion for screwing the screw. Rotation preventing protrusions are protruded at a predetermined interval along the periphery of the lower portion of the finishing cap; Wherein the shelf through-hole inner wall surface is provided with a latching jaw for restricting the rising of the support rod; And the protruding guide groove is formed in the engaging jaw so that the rotation preventing protrusion can be inserted.

According to the present invention, it is possible to easily assemble the finishing cap and the support bar in the shelf located at the uppermost end of the cart, thereby improving the assembly and separation efficiency of the product.

Particularly, by changing the through-hole structure of the shelf in which the finishing cap is coupled, the upper shelf, the lower shelf and the lower shelf are unified so that the upper shelf and the shelves of the middle shelf and the lower shelf need not be separately stored or managed separately, This shows the advantage of reducing the production cost of the product.

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

First, a structure of a cart for carrying articles according to an embodiment of the present invention will be described with reference to FIG. 1, wherein a plurality of shelves 100 are supported by a support bar 110 in a multi- A through hole 101 for fastening the support rod 110 is formed at the corner of each shelf 100 and a through hole 101 is formed in the shelf 100 provided at the uppermost stage to prevent the through hole 101 from being exposed to the outside And a finishing cap 120 is fastened to the finishing cap 120. The finishing cap 120 is formed with a male screw portion 111 formed at the upper end of the support rod 110 and a female screw portion 121 for fastening the screw, And a locking protrusion 102 for restricting the lifting of the support bar 110 is formed on the inner wall surface of the shelf through hole 101, The protrusion guide groove 103 is formed in the locking protrusion 102 so that the rotation preventing protrusion 122 can be inserted .

Particularly, it is preferable that a curved surface portion 122a having a predetermined curvature shape is formed on the corner of the rotation preventing protrusion 122 so that insertion can be easily guided into the protrusion guiding groove 103.

The locking protrusions 122 and the protrusion guide grooves 103 are repeatedly provided at predetermined intervals along the inner wall surface of the through hole 101. The rotation protrusion 122 is formed in the protrusion guide groove 103, And are formed in the same number in corresponding positions.

Hereinafter, an operation and effect of assembling and fastening the support bar to the upper shelf of the cart according to the present invention will be described.

First, in order to fasten the support rod 110 to the shelf 100, the male cap portion 111 provided at the upper end of the support rod 110 is fastened with the finishing cap 120 inserted into the through hole 101, .

That is, at this time, the male screw portion 111 is screwed to the female screw portion 121 of the finishing cap 120. In the process of screwing, the finishing rod 110 is rotated The rotation preventing protrusion 122 formed on the lower portion of the cap 120 is inserted into the protrusion guide groove 103 to prevent the rotation of the finishing cap 120 and thus the stable connection with the support rod 110 is achieved.

Particularly, in the process of assembling the finishing cap 120, the curved portion 122a formed at the corner of the rotation preventing protrusion 122 facilitates insertion into the projection guide groove 103, And the support rod 110 can be easily assembled.

10 and 11 illustrate a cart assembly structure according to another embodiment of the present invention. A mounting groove 122b is formed on an outer wall surface of the rotation preventing protrusion 122, It is confirmed that a ball-shaped support 105, which is elastically supported by an elastic spring 104, is formed on the wall surface of the through hole 101.

When the rotation preventing protrusion 122 is inserted into the protrusion guiding groove 103, the retaining groove 122b is caught by the retaining groove 105. Accordingly, when the rotation preventing protrusion 122 is inserted into the protrusion guiding groove 103, So that it is possible to prevent the phenomenon that the finishing cap 120 is separated from the through hole 101 during the use of the cart.
