The invention provides a supporting frame which is convenient to package and install in order to overcome the defects in the prior art.
In order to achieve the above purpose, the present invention adopts the following technical scheme:
the utility model provides a braced frame of desk for connect the table leg and the table of desk, braced frame includes first crossbeam, second crossbeam and connects the connecting device of two, braced frame passes through connecting device at installation state and packing state switch, first crossbeam and second crossbeam are in interval under the packing state is L1, first crossbeam and second crossbeam are in interval under the installation state is L2, L1 < L2, braced frame's installation state is used for installing with the table and/or the table leg of desk and prepositioning, be equipped with the connecting hole that is used for being connected with the table and/or the table leg of desk on first crossbeam and the second crossbeam.
In the technical scheme, the first cross beam, the second cross beam and the connecting device form the supporting frame, so that the supporting frame can be switched between an installation state and a packaging state. The desk board and/or the desk legs of the desk are provided with mounting holes corresponding to the connecting holes, and in the mounting state, the connecting holes on the supporting frame are aligned with the mounting holes on the desk board and/or the desk legs of the desk, so that end users can quickly assemble other accessories such as the desk legs; when in a packaging state, the distance between the first cross beam and the second cross beam is reduced, so that the volume of the supporting frame during transportation can be reduced, the packaging volume is reduced, and the packaging cost is reduced. The connecting device enables the first cross beam and the second cross beam to have adjustable intervals, and can be adapted to table legs of various sizes and models.
Preferably, the first beam and the second beam are in close contact with each other in the packaged state. The first cross beam and the second cross beam are tightly attached under the packaging state, so that the volume of the supporting frame during transportation can be reduced as much as possible, the transportation is convenient, the first cross beam and the second cross beam can be mutually supported under the packaging state, the deformation is not easy, and the transportation loss is reduced.
Preferably, in the mounted state, the connection means restricts relative displacement of the first and second beams in the support frame length direction. Under the installation state, the structure can make first crossbeam and second crossbeam have the locate function in length direction, makes braced frame can be fast from packing state to installation state switch in place, has reduced the locating time in length direction when assembling, other accessories such as the quick assembly table leg of being convenient for.
Preferably, the connecting device comprises at least two plate bodies which are connected in sequence, the adjacent plate bodies can be folded relatively, the plate bodies at the head end and the tail end are respectively connected with the first cross beam and the second cross beam, and when the supporting frame is switched from the installation state to the packaging state, the at least two plate bodies are folded relatively and wrapped outside the first cross beam or the second cross beam.
In the above technical scheme, the plate body is hard material, can guarantee that first crossbeam and second crossbeam can only follow braced frame's width direction upset, under the installed state, guarantees the accuracy of first crossbeam and second crossbeam in the relative position of length direction. The number and width of the intermediate plates may be set according to the spacing between the first and second cross members in the installed state. The plate body is flat plate structure, and braced frame is in the packaging state, and the plate body parcel is in first crossbeam and the second crossbeam outside, can not increase the size when braced frame folds hardly, also can not too much protruding first crossbeam and the major structure of second crossbeam, both can reduce the packaging cost, also can avoid the problem that convex structure damages in the transportation easily. In the packed state, the dimension in the length direction is not increased in the support frame. The connecting device can keep a certain distance between the first cross beam and the second cross beam in the installation state, and meanwhile, the relative positions of the first cross beam and the second cross beam in the length direction of the supporting frame can be determined, so that the first cross beam and the second cross beam cannot be inclined, and the installation of workers is further facilitated.

The first transverse beam 4.1 and the second transverse beam 4.2 are in contact with each other in the packaged state. In the mounted state, the connecting means 5 limit the relative displacement of the first beam 4.1 and the second beam 4.2 in the length direction of the support frame 4. In fig. 1, the X direction is the width direction of the support frame 4, the first beam 4.1 and the second beam 4.2, and the Y direction is the length direction of the support frame 4, the first beam 4.1 and the second beam 4.2.
In the above technical scheme, the first beam 4.1, the second beam 4.2 and the connecting device 5 form the supporting frame 4, so that the supporting frame 4 can be switched between an installation state and a packaging state. In the installed state, the end user can quickly assemble other accessories such as the table legs 3 and the like; when in a packaging state, the distance between the first cross beam 4.1 and the second cross beam 4.2 is reduced, so that the volume of the support frame 4 during transportation can be reduced, the packaging volume is reduced, and the packaging cost is reduced. The first cross beam 4.1 and the second cross beam 4.2 are tightly attached in the packaging state, so that the size during transportation can be reduced as much as possible, the transportation is convenient, the first cross beam 4.1 and the second cross beam 4.2 can be mutually supported in the packaging state, the deformation is not easy, and the transportation loss is reduced.

In another embodiment, the number of the connecting devices 5 is two, and the two connecting devices 5 are arranged at intervals along the length direction of the first beam 4.1. The structure can increase the overall structural stability of the support frame 4, and the accuracy of the positioning position between the first beam 4.1 and the second beam 4.2 can be further increased when the support frame 4 is in the installation state.
In another embodiment, the first beam 4.1 and the second beam 4.2 are each tubular hollow structures.
Example 2: as shown in fig. 2 and 3, the connecting device 5 includes 5 plate bodies 9 connected in sequence, the adjacent plate bodies 9 can be folded relatively, and the plate bodies 9 at the front end and the rear end are respectively fixed with the first beam 4.1 and the second beam 4.2. The cross sections of the first cross beam 4.1 and the second cross beam 4.2 are square, when the supporting frame 4 is in a packaging state, 5 plate bodies 9 are respectively attached to the outer contours of the first cross beam 4.1 and the second cross beam 4.2, the number of the side faces attached to the plate bodies 9 on the first cross beam 4.1 is 3, and the number of the side faces attached to the plate bodies 9 on the second cross beam 4.2 is 2. When the support frame 4 is in the installation state, the number of the side faces attached to the plate body 9 on the first beam 4.1 is 1, the number of the side faces attached to the plate body 9 on the second beam 4.2 is 1, and the connecting device 5 limits the first beam 4.1 and the second beam 4.2 to translate away from each other in the packaging state of the support frame 4.
