Box skeleton structure

This creation department is related to industrial cabinets; in particular, it refers to a box skeleton skeleton structure.

Known industrial cabinets (such as cabinets, transformer boxes, etc.) are mostly used to provide power distribution or component placement for board use, and are one of the facilities for power supply or mechanical equipment.

In general, the cabinet structure of an industrial cabinet is formed by a combination of a skeleton and a plurality of rigid sheets. The skeleton is formed by passing the long angle iron and cutting it into a suitable length, and then combining the angle irons.

The structural feature of the traditional angle iron is that the angle shape of the angle iron is L-shaped, two pieces of mutually perpendicular plates are integrally formed, and each of the plates is formed with a plurality of elongated holes for use as a locking hole for locking the alignment. . Therefore, when assembling the skeleton, one end of each angle iron plate is overlapped with one end of the other angle iron plate at one end, and the overlap is welded to improve the bonding strength between the two angle irons.

However, the structural design of the aforementioned angle iron does not allow the assembler to quickly and appropriately adjust the alignment position, thereby causing the assembler to take extra time to complete the assembly and fixing operations, thereby delaying the assembly speed; in addition, due to the general commercial availability The angle iron itself often has manufacturing errors, and when the box is assembled, the alignment error between the angle irons often occurs, thereby increasing the difficulty of assembly. In addition, in the process of welding the reinforcing bracket and the angle iron, the angle iron will be affected by the heat conduction at the welding place, which will cause the angle iron to be deformed by heat (especially the center of the angle iron is more likely to be distorted or expanded due to heat. The situation causes the assembled skeleton to exhibit a non-rectangular deformation form, or the angular length of the angle iron will cause a change in the original length, and the consequences will also result in a situation in which the finished form of the skeleton does not conform to the design appearance. In this way, the assembly personnel in the assembly work of the box skeleton makes it necessary for the assembler to use the tool to beat or strike the angle iron deformation to correct the deformation. However, the beating or tapping operation is done manually. There must be a certain amount of error, so that the design of the box skeleton assembled by using the angle iron not only causes an increase in assembly time and difficulty, but also can effectively and accurately control the assembled size. Therefore, the above-described manner of assembling the frame skeleton using the angle iron is still not perfect, and there is still room for improvement.

The purpose of the present invention is to provide a box skeleton structure and a manufacturing method thereof, which are convenient for the assembly personnel to quickly and accurately align the positions, and can complete the assembly work of the box skeleton structure in a short time.

In order to achieve the above object, the present invention provides a box skeleton structure including an upper frame and a lower frame, and a plurality of brackets connecting the upper frame and the lower frame, wherein the upper frame and the lower frame are characterized by At least one of the frame body includes a plurality of side plates disposed along a circumference of the frame body, each of the two side plates has a joint portion at each end thereof, and a space is spaced apart from the joint portion of the adjacent side plate; the brackets respectively include Adjacent one of the first side panel and the second side panel, and each bracket has a combined portion on the first side panel and the second side panel at least one end, wherein the first side panel is joined The joint portion of the second side panel is coupled to the joint portion of the other side panel.

The effect of the creation is that the assembly of the skeleton structure of the box can be completed quickly, and the precise alignment and the deformation of the overall structure of the box are achieved.

In order to explain the present invention more clearly, two preferred embodiments will be described in detail with reference to the drawings.

The side plates 14 are disposed along the circumference of the main frame plate 12, and each of the two sides of the side plate 14 has a joint portion 141. In this embodiment, each of the joint portions 141 is a bump. The end edge of the side plate 14 is convexly formed outward. In addition, two of the side plates 14 are respectively provided with a connecting portion 142, and each of the connecting portions 142 is located between the two connecting portions 141 of the corresponding side plates 14. In this embodiment, each of the connecting portions 142 is a groove. The first fluted plate 16 is connected to the periphery of a side plate 14 , and the side plate 14 is not provided with a connecting portion 142 .

When the frame plate 101 is bent, a force is applied to each of the side plates 14 such that each of the side plates 14 is perpendicular to the main frame plate 12; and a force is applied to the first groove plate 16 The first groove plate 16 and the corresponding side plate 14 are disposed at an angle (90 degrees in this embodiment), so that the frame plate 101 is bent into the upper frame 10. The joint portion 141 of each side plate 14 of the upper frame body 10 is spaced apart from the joint portion 141 of the adjacent side plate 14 by a distance; the first groove plate 16 extends outward from the periphery of the corresponding side plate 14. Used as a guiding groove to guide rainwater.

It is worth mentioning that the concave-convex configuration between the joint portions 321 and 341 of each bracket 30 and the joint portion 141 of the side plate 14 helps the assembler to accurately and accurately align the position to improve the assembly efficiency. After design, the surface of the joint between the upper and lower frames 10, 20 and the bracket 30 is more flat, and thereby obtains a box structure 1 of a positive rectangular shape, which improves the assembly of the plate in the past due to the deformation of the box structure. Unexpected.

Furthermore, in the present embodiment, in the present embodiment, the thermal deformation of the upper frame body 10, the lower frame body 20 and the bracket 30 during welding is caused by the unevenness between the joint portions 321 and 341 and the joint portion 141. The design occurs at the structure of the protrusion or the recess, and the severe deformation of the upper frame 10, the lower frame 20 and the bracket 30 during welding can be prevented. In addition, the welding range of the upper frame body 10, the lower frame body 20, and the bracket 30 during welding is located in a region where the solder is filled, that is, between the joint portions 321 and 341 of the uneven portion and the joint portion 141, which is greatly reduced. The heating range between the upper frame 10, the lower frame 20 and the bracket 30 occurs to reduce structural deformation.

It is noted that the two brackets 30 in the embodiment further comprise a second groove plate 36, one of which is coupled to the first side plate 32 of the bracket 30, and the other is coupled to the other. The second side plate 34 of the bracket 30 is biased. When the two bracket plates are bent, the two second groove plates 36 are respectively applied with force, so that the two second groove plates 36 respectively correspond to An angle (90 degrees in this embodiment) is disposed between the side plates, and the two second groove plates 36 are respectively butted to one end of the first groove plate 36, thereby being connected to the first groove plate 16 Together form a guiding groove that guides the rainwater.

The purpose of each of the reinforcing frames 40 is to improve the overall strength of the frame structure 1 . Please refer to FIG. 8 and FIG. 1 . When assembling, the reinforcing frame 40 is also welded to the upper frame 10 and the lower frame. In the body 20, the solder is filled between the connected portions 421 and 441 of each of the reinforcing frames 40 and the main frame plate 12, and the connected portions 421, 441 and corresponding ones of the reinforcing frames 40 are filled.
