The wall fixing frame is U-shaped as a whole with its opening facing outward.

The utility model has the beneficial effects that: by adopting the two components of the sliding support rod and the self-locking handle, the chute is processed on the desktop support frame at the same time; the self-locking handle uses the gravity to clamp the sliding support rod, thereby making the whole folding The mechanism is not loose; when it is necessary to fold the table support frame, press the self-locking handle upwards, and the sliding support bar will be detached from the slot of the self-locking handle to separate from the self-locking handle, so that the sliding support rod edge The folding work can be completed by moving the chute outwards. When the desktop support frame needs to be unfolded, as long as the table support frame is turned upside down, the slide support bar will be automatically fixed in the card slot along the chute inwardly to prevent the table support frame from moving downward.

detailed description

Referring to FIGS. 1 to 4, the folding mechanism of FIG. 1 includes two sets of folding assemblies 1, each of which includes a wall fixing frame 11 fixed to the wall and a table supporting frame 12 supporting the table board 3. , one connector 13, two A sliding support bar 14 for folding the table top support frame 12, and a self-locking handle 15 for supporting and fixing the sliding support bar 14. In practical applications, the number of folding assemblies 1 can also be increased.

The wall fixing frame 11 is formed in a U-shape as a whole, similar to the channel steel structure, and the opening thereof faces outward. The bolt hole 2 of the mounting bolt 16 is machined in the upper position and the top end position of the wall fixing frame 11 to fit the wall surface. There is also a corresponding mounting hole on the face, which is not shown in the figure.

The connecting member 13 is also a common channel steel structure, and its function is to hingely mount the wall fixing frame 11 and the table top supporting frame 12 by bolts 16. After the table top supporting frame 12 is folded, the table supporting frame 12 and the wall fixing frame 11 can Folded into a two-layer structure.

The table top support frame 12 is also U-shaped as a whole, and is also similar to a channel steel structure. The sides of the two sides have a long sliding groove 121, and the sliding groove 121 functions to fold and unfold the top end of the sliding support rod 14. A horizontal movement space is provided, and a bolt hole 2 is also provided below the chute 121.

There are two sliding support rods 14 in the middle. Each of the sliding support rods 14 has a straight rod in the middle. The ends of the sliding support rods 14 are zigzag. The Z-shaped middle has bolt holes 2 for mounting bolts 16, and the sliding support rods 14 can be respectively hinged by bolts 16. On the sliding frame 121 of the wall fixing frame 11 and the table top support frame 12, the sliding support bar 14 is always above the self-locking handle 15 during horizontal movement.

The self-locking handle 15 is generally V-shaped, that is, the two sides form a certain oblique angle with each other, wherein the outwardly facing outer end 153 of the self-locking handle 15 is significantly heavier than the inwardly facing inner end 152; the self-locking handle 15 has a U inside. The groove is formed, so that the manufacturing cost is saved; the eccentric gravity adjusting hole 155 is disposed near the inner portion of the self-locking handle 15 at the inward eccentric position of the self-locking handle 15, and the bolt 16 is mounted on the eccentric gravity adjusting hole 155 to The lock handle 15 is fixed on the table support frame 12 and is up and down on the table support frame 12, while the self-locking handle 15 is in the eccentric position by the eccentric gravity adjustment hole 155 and the weight of the outer end 153 is significantly larger than End 152 The weight allows the sliding support bar 14 to be easily disengaged or joined from the slot 154 of the inner end 152 of the self-locking handle 15, without the need for too much labor.

The outer end 153 of the self-locking handle 15 has an outwardly extending handle block 151 which, under the action of the hand, allows the sliding support bar 14 to be removed from the slot 154 on the inner end 152 of the self-locking handle 15. Move up and lift the desktop board 3 when you need to expand the desktop.

Referring to Figure 6, the folding table shown in the figure differs from the conventional folding table in that the folding mechanism described above is selected, and the table top 3 is a commonly used component.
