Detailed Description
Preferred embodiments of the present invention will be described below with reference to the accompanying drawings. It should be understood by those skilled in the art that these embodiments are only for explaining the technical principle of the present invention, and are not intended to limit the scope of the present invention. It should be noted that in the description of the present invention, the terms "front", "back", "upper", "lower", "left", "right", "vertical", "horizontal", "inner", "outer", etc. indicate directions or positional relationships based on those shown in the drawings, which are merely for convenience of description, and do not indicate or imply that the device or element must have a specific orientation, be constructed and operated in a specific orientation, and thus, should not be construed as limiting the present invention.
In this embodiment, the connection mechanism is described by taking the connection between the upper frame 1 and the right frame 2 of the file cabinet as an example.
As shown in fig. 1, the right frame 2 is formed by folding a right side plate, so that the right side plate and the right frame 2 are integrated. By the design, the number of components of the file cabinet is reduced; secondly, the seams are reduced, so that the whole file cabinet is more beautiful. In order to strengthen the strength of the right frame 2 and reduce the difficulty of the side plate metal plate, the reinforcing plate 22 with a groove-shaped structure is buckled and connected with the back of the right frame 2 in a spot welding manner, so that the right frame 2 forms a closed square tube structure. A row of spacer mounting holes is punched in the reinforcing plate 22 for height adjustment of the spacer 8. The upper end of the right frame 2 is provided with an insertion groove for inserting the upper door frame 1, when the door frame is assembled, the upper door frame 1 is inserted into the insertion groove, and the insertion groove plays a role in supporting and limiting the upper door frame 1, but the supporting and limiting can not ensure the verticality of the connection between the upper door frame 1 and the right frame 2.
As shown in fig. 2, a vertical fastening groove 11 is provided on the front surface of the upper door frame 1, and a fastening flange 21 corresponding to the fastening groove 11 is provided on the right frame 2. In the figure, the right frame 2 is cut off by the insertion groove and the rest part is the buckling flanging 21, and the buckling flanging 21 is buckled in the buckling groove 11 during assembling. In order to ensure the fastening tightness, the width of the fastening groove 11 is slightly larger than the thickness of the fastening flange 21. In the present embodiment, the engagement groove 11 may be through-penetrating, may not be through-penetrating, or may be discontinuous through-penetrating. In this embodiment, the fastening slot 11 is through. The snap groove 11 is used for providing a positioning reference for the vertical connection of the right frame 2 and the upper door frame 1.
As shown in fig. 3, the upper door frame 1 is made by a sheet metal process, the back of the upper door frame 1 is provided with an inward flange 12, a right-angle connecting plate 3 is connected to the inner side surface of the inward flange 12 by spot welding, and the right-angle connecting plate 3 is connected to a reinforcing plate 22 on the right frame 2 by a tapping screw. The right-angle connecting plate 3 is used for improving the strength and the stability of the vertical connection between the right frame 2 and the upper door frame 1. The right-angle connecting plate 3 is designed separately, not integrally with the upper door frame 1, because the right-angle connecting plate 3 needs to provide larger connecting strength, so the plate thickness must be thicker, if the plate thickness of the upper door frame 1 is increased, the cost is increased, so the more reasonable scheme is to spot-weld the thicker right-angle connecting plate 3 on the upper door frame 1.
The back of the upper door frame 1 is provided with an outward flange 13 which is in contact with and positioned by the reinforcing plate 22, and the outward flange 13 has the function of providing a flange for closing the door; secondly, press from both sides between right angle connecting plate 3 and right frame 2, play the effect of reinforcing to the fixed of upper doorframe 1.
During assembly, the upper door frame 1 is inserted into the insertion groove of the right frame 2, then the back of the upper door frame 1 is patted, so that the buckling groove 11 on the front surface of the upper door frame 1 is buckled with the buckling flanging 21 on the right frame 2, and at the moment, the right frame 2 and the upper door frame 1 are in a vertical state; and finally, the right-angle connecting plate 3 and the right frame 2 are fixedly connected through self-tapping screws. This connection structure easily assembles, and the important has guaranteed the straightness requirement that hangs down that last door frame 1 and right frame 2 are connected, and has guaranteed this straightness's joint strength and the stability of connecting that hangs down.
A sectional filing cabinet, as shown in fig. 4, is provided with a pair of split doors, and the left and right door panels 6, the left and right side panels, the upper top panel, the lower bottom panel, the rear panel 7, and the upper and lower door frames of the sectional filing cabinet are all detachably assembled. Wherein, the left and right side plates and the left and right frames are designed into a whole. In addition to the above connection structure adopted by the upper door frame 1, the left frame 5 and the right frame 2, as shown in fig. 5, the connection structure also adopted by the lower door frame 4, the left frame 5 and the right frame 2 can ensure the overall squareness and stability of the assembled file cabinet and ensure the smooth opening and closing of the split doors.
In order to reduce the size of the packing box and the transportation cost, as shown in fig. 6, the rear plate 7 is formed by buckling and connecting two splicing plates, and the ratio of the width of each splicing plate to the width of the side plate is within 0.8-1.2. Because the width of every splice plate is close with the width of single door plant 6, and the width of controlling the curb plate also is close with the width of single door plant 6, like this, each board can range upon range of puts into the packing box, and the length and width size of packing box just also slightly is greater than the length and width size of single door plant 6, can accomplish the volume minimum to packing and cost of transportation have been reduced.
The part of the utility model not detailed is prior art. Although embodiments of the present invention have been shown and described, it will be appreciated by those skilled in the art that changes, modifications, substitutions and alterations can be made in these embodiments without departing from the principles and spirit of the invention, the scope of which is defined in the appended claims and their equivalents.
