Frame assembling mechanism

Abstract

PURPOSE: To provide an assembling structure of a housing, where its mechanical strength is reinforced when its ceiling plate, bottom plate, left side-plate, and right-side plate assemble themselves in the form of a frame, and a portion of such fastening members as its screws and rivets are so prevented from exposing its external surfaces so as to enhance the external appearance. CONSTITUTION: In the assembling structure of a housing, a front-side lateral-edge bent surface 5C3 and a rear-side lateral-edge bent surface 5C51 of a left side- plate 5C are so made to butt respectively against front-side and rear-side left-end bent surfaces 5A3, 5A6 of a ceiling plate 5A that the butting surfaces against each other are respectively jointed to each other with rivets 19 from the intra- frame direction of the housing. Similarly, in the other corners of the housing, L-shaped bent surfaces are so made to butt against each other from the left and right directions and the butting surfaces against each other are respectively jointed to each other with rivets.

Description

technical field [0001] The present invention relates to a frame assembly mechanism used for machine storage trays such as automatic control trays. Background technique [0002] In the prior art, as a machine storage tray, there is an automatic control panel installed on the wall. Inside the automatic control panel are installed the basic module, control module, power supply module, etc. as the equipment in the panel. Figure 9 It shows the frame assembly mechanism of the automatic control panel in the prior art. Figure 9 Among them, 11 is a frame body, and 12 is a door mounted on the front of the frame body 11 so as to be openable and closable via hinges 13-1 and 13-2. The housing 11 is composed of a frame-shaped housing body 11-1 and a rear panel 11-2. The frame body 11-1 is composed of a top plate 11A, a bottom plate 11B, a left side plate 11C, and a right side plate 11D. [0003] The rear panel 11-2 is joined to the rear surface of the housing main body 11-1 by welding...

Problems solved by technology

[0006] (2) Due to the proficiency of the operator, the welding is sometimes uneven. Therefore, when coating the decoration, it is necessary to cover the welded part with putty, and the putty is evenly ground, which increases the cost.

[0007] (3) After welding, it must be coated with decoration, so the delivery period is extended (cannot be welded after coating decoration)

[0008] (4) Since the frame body 11 with the door 12 installed is transported, a large space is required during transport, and even if the frame body 11 and the door 12 are transported separately, a large space is also required.

[0009] (5) Since the frame body 11 with the door 12 is stored in the warehouse, a large warehouse space is required

Therefore, when the top plate 11A, bottom plate 11B, left side plate 11C, and right side plate 11D are assembled into a frame shape and formed into a frame body 11 on site, the mechanical strength is poor and it is easy to deform.

That is, in Figure 10 In , when a force is applied from the A direction, it is easy as Figure 11 deformation as shown

In addition, since the head of the screw 14 is exposed on the outer surface, the appearance is not good

Even if fixing parts such as rivets are used instead of screw 14, the same problem exists
