The present invention relates to a drawer assembly structure of iron furniture, and more specifically, to produce a steel desk or file box drawer in the subcontracting factory when delivered to the finished product factory does not bend the drawer in the box-type delivery, supply in the form of a plate Therefore, it is possible to transport a large amount at a time, which can significantly reduce the transportation cost. In a finished product factory, it can be easily assembled and assembled by human power without using a bending machine to improve the productivity of the finished product, as well as to drawers. The front plate is to provide a drawer assembly structure of iron furniture that can be combined without performing a welding action to reduce the cost of welding work. Generally, furniture is mainly made of wood, resin, iron, etc., and is produced in a shape and size appropriate for its purpose. In particular, the iron furniture made by cutting and forming the iron plate has a desk, a drawer, a wagon, a file box, a bookshelf, a cabinet, and the like. The drawer of the above-mentioned iron furniture is made of iron plate by bending the main body into a "c" shape, the front panel is assembled with a front plate made of iron or wood surface plate and a back plate, and the back plate made of iron plate is welded on the back side. It is made in a box shape, and the finished product factories that make these iron furnitures do not make drawers by division of labor, and are mainly receiving and using those made in subcontractors. However, the drawer body for iron furniture manufactured in the existing subcontracting factory is to bend both sides of the plate body of considerable thickness as it is, so it requires considerable force. Because of the need to bend this is a time-consuming closure.

In other words, in the manufacturing process of making a drawer in the subcontracting factory, first, the iron plate is cut to a predetermined size, and then bending, perforation, and flange formation of the necessary parts are performed by a bending device and a press machine to make a plate for the drawer, and then the plate is again made. It is placed in the bending device and bent at both sides at a right angle to make both side walls 12 and the bottom 11 of the drawer body 10 as shown in FIG. However, bending both sidewalls 12 of the drawer body 10 with a bending machine as described above has a problem that it takes a long time, and also when the drawer is supplied to the finished product factory in the subcontracting factory, the drawer is made into a box shape. As it is transported in the state, a drawer made in a box shape is bulky and thus cannot be loaded in a heavy load of a freighter, so it is expensive to transport as it is divided into several units. In addition, a front plate 15 composed of a surface plate 13 and a back plate 14 is attached to the front of the drawer body 10. In order to attach the front plate 15 to the drawer body 10, work is performed. Since a complicated welding means must be used, the cost of the welding operation is added, as well as an excessive time, and thus there is a problem that the productivity is considerably reduced.

Therefore, the present invention was invented to solve the conventional problems as described above, the object of the present invention is to transport a large amount at a time when delivering the drawer body to the finished product factory in the subcontracting factory to reduce the logistics cost, finished product In the factory, the side wall of the drawer on the plate can be easily bent by the hand without using the bending device, which can improve the convenience and productivity, and also weld the front plate attached to the front of the drawer. It provides a drawer assembly structure of steel furniture that can be attached to the drawer without going through, thereby reducing the cost of eliminating welding work and improving productivity. The object of the present invention is to form a plurality of cut holes in a row at the boundary between the bottom and both wall parts to easily bend the wall portion by hand, a plurality of bolt holes are perforated at the leading edge of the bottom and wall portion The flange part is formed, and a plurality of cutting holes are formed in a line at the boundary between the bottom part and both wall parts so that the wall part can be easily bent by hand, and the bolt hole is positioned at a position corresponding to the bolt hole punched in the flange of the wall part. The front plate consisting of the perforated back plate and the surface plate is characterized in that it is attached to the drawer. The present invention is to be able to easily bend the wall surface with the other hand in the state in which the operator grasps the floor with one hand without using a separate bending device in the finished product factory, the plate body delivered from the subcontractor. When attaching the front plate to the drawer body by fastening with a bolt in a state of being in contact with each other can achieve the above object effectively.

Hereinafter will be described in detail by the accompanying drawings, the technical configuration and the effect to achieve the object of the present invention in a preferred embodiment as follows.

Figure 2 is a perspective view of a drawer body according to the present invention and Figure 3 is a perspective view showing a process of assembling the drawer body made of a plate of the present invention in a box shape, Figure 4 shows a state in which the drawer of the present invention is completed As shown in this perspective view, the present invention provides a plurality of cutouts 130 along a portion for distinguishing the bottom portion 110 and the two wall portions 120 when press forming the iron plate to a predetermined size to make a drawer. Formed in a row is characterized in that the drawer body 100 is formed so that both the wall portion 120 can be easily bent by a worker by hand. In addition, at the front edges of the bottom part 110 and both wall parts 120, a flange part 121 having a plurality of bolt holes 122 formed therein is formed, and a front plate attached to the front of the drawer body 100. The back plate 142 of the surface plate 141 and the back plate 142 forming the 140 is characterized in that the bolt hole 143 was punched at a position coinciding with the bolt hole 122. Reference numeral 150 is a rear plate, 160 is a bolt for coupling the front plate and the drawer body. The present invention configured as described above is not delivered in a box shape at the time of delivery from the subcontracting factory to the finished product factory, that is, the front plate 140 and the rear plate 150 to be separated from the drawer 100, both wall parts ( 120) is delivered in a laid-up state rather than in an upright position, so that when it is loaded in a transport vehicle, it can be stacked on top of one another so that a large amount can be loaded in a single vehicle, thereby significantly reducing the transportation cost. It is. After the delivery from the subcontracting factory to the finished product factory, the worker only needs to set up both wall parts 120 with the other hand while holding and fixing the bottom part 110 of the drawer 100 with one hand. The partition portion between the 110 and the wall portion 120 is formed with a plurality of cutting holes 130 to be easily folded so that the partition portion is easily folded without applying excessive force, so that the wall portion 120 is erected. The bottom part 110 and the wall part 120 maintain the right angle state. After standing both wall parts 120 as described above, the front plate 140 and the rear plate 150 are coupled to the drawer 100, and the front plate 140 is the front plate 141 and the back plate 142. Since the front plate 140 is brought into close contact with the drawer 100 because the back plate 142 is in contact with the drawer 100, the bottom part 110 and the wall of the drawer 100 are formed. (120) A flange portion 121 in which a plurality of bolt holes 122 are drilled is formed at the leading edge, and the back plate 142 has the same number of bolt holes 122 drilled in the flange portion 121 as well. If the bolt hole 143 is perforated and the front plate 140 is in close contact with the drawer 100, the bolt hole 122 and the bolt hole 221 are coincident with each other. Then, the bolt 160 is inserted into the bolt hole 122 drilled into the flange portion 121 of the wall portion 120 and fastened to penetrate to the bolt hole 143 of the back plate 142. And the drawer 100 is firmly coupled to each other. Therefore, it is possible to attach the front plate 140 to the drawer 100 without going through a separate complicated welding work as before, thereby improving productivity.

In this way, the present invention can deliver a drawer from the subcontracting factory to the finished product factory to the plate body when stacked in the transport vehicle can be stacked on top of each other to load a larger amount of goods in one car can reduce the logistics cost Of course, even in the finished product factory, it is possible to easily raise the wall surface of the plate body by the worker's hand without using a separate bending machine, thereby improving productivity. In addition, when the front plate is attached to the drawer body is coupled to each other without performing a welding operation is a very useful invention that can improve the assembly as well as the cost savings due to the deletion of the welding operation.
