In the existing furniture, when widening the plane of the furniture, folding brackets are often used. However, the existing folding brackets have single positioning, and the structure is less stressed. At the same time, when not in use, the ordinary folding bracket cannot be completely folded, which greatly occupies the effective space of the furniture.

Utility model content

The purpose of this utility model is to propose an adjustable folding bracket with a relatively large structural force in view of the above-mentioned deficiencies.

The technical scheme that the utility model adopts is:

An adjustable folding bracket, including a groove-shaped fixed rod, a groove-shaped rotating rod, a groove-shaped oblique rod and a spring, one end of the groove-shaped fixed rod is hinged with the groove-shaped rotating rod, and the groove-shaped fixed rod The middle and lower part is hinged with one end of the trough-shaped slanted strut, the other end of the trough-shaped slanted strut is connected with the trough-shaped rotating rod, and the groove-shaped fixed rod and the trough-shaped slanted strut pass through The spring is connected, and the spring forms a certain tension between the groove-shaped fixing rod and the groove-shaped oblique support rod.

Further, one end of the grooved fixed rod is hinged with the grooved rotating rod through a first pin shaft.

Further, the middle and lower part of the groove-shaped fixed rod is hinged with one end of the groove-shaped oblique support rod through the second pin shaft.

Further, the other end of the trough-shaped oblique strut is connected to the trough-shaped rotating rod through positioning teeth.

Furthermore, the positioning tooth is formed on the grooved rotating rod.

Further, a punching hook is installed on the groove-shaped fixing rod and the groove-shaped inclined support rod, and the spring is fixed on the punching hook.

Further, screw holes are opened on the grooved rotating rod.

Preferably, there is at least one screw hole.

The beneficial effects of the utility model are:

The device has a simple structure and low production cost; the device can be completely folded when it is folded, which greatly reduces the effective space occupied by the device; The device can withstand large loads.

Description of drawings

Fig. 1 is a structural schematic diagram of an adjustable folding support provided by an embodiment of the present invention when it is unfolded;

Fig. 2 is a structural schematic diagram of an adjustable folding stand provided by an embodiment of the present invention when it is folded.

Among the figure: 1, trough-shaped fixed rod, 2, trough-shaped oblique support rod, 3, trough-shaped rotating rod, 4, spring, 1-1, first pin shaft, 1-2, second pin shaft, 3-1 , screw holes, 3-2, positioning teeth.

Detailed ways

Below in conjunction with accompanying drawing, the utility model is described further.

Referring to FIG. 1 and FIG. 2 , this embodiment provides an adjustable folding bracket, including a groove-shaped fixed rod 1 , a groove-shaped rotating rod 3 , a groove-shaped oblique rod 2 and a spring 4 . One end of the grooved fixed rod 1 is hinged with the grooved rotating rod 3 through the first pin shaft 1-1. The middle and lower part of the grooved fixed rod 1 is hinged with one end of the grooved oblique strut 2 through the second pin shaft 1-2. The other end of the grooved oblique strut 2 is connected with the grooved rotating rod 3 through the positioning teeth 3-2. The groove-shaped fixed rod 1 and the groove-shaped oblique strut rod 2 are connected by a spring 4, and the groove-shaped fixed rod 1 and the groove-shaped oblique strut rod 2 are equipped with punching hooks, and the spring 4 is fixed on the punching hook. The spring 4 forms a certain tension between the groove-shaped fixed rod 1 and the groove-shaped oblique support rod 2 . Since the groove-shaped fixed rod 1, the groove-shaped rotating rod 3 and the groove-shaped oblique support rod 2 all adopt a groove-shaped structure, and they cooperate with each other, the whole device can bear better force, can withstand larger forces and maintain stability . Have three screw holes 3-1 on the grooved turning bar 3.

When using this device, referring to Figure 1, it is only necessary to lift the trough-shaped rotating rod 3 to the corresponding angular position, and at the same time let the trough-shaped oblique strut 2 rotate, so that the free port of the trough-shaped oblique strut 2 is clamped into the groove-shaped rotation On the corresponding positioning tooth position 3-2 of the rod 3, then fix the groove-shaped fixing rod 1 to the corresponding position to be widened by screws, and finally pass the screw to widen the panel through the screw hole on the groove-shaped rotating rod 1 3-1 can be fixed on the trough-shaped rotating rod 1, so that the panel has the effect of widening and can bear a large load at the same time. When the device does not work and needs to be folded, with reference to Figure 2, lift the trough-shaped rotating rod 3 a little, turn the trough-shaped inclined support rod 2 downwards, and put down the trough-shaped rotating rod 3 at the same time, so that all the trough-shaped rods are folded into One.

The device has a simple structure and low production cost; the device can be completely folded when it is folded, which greatly reduces the effective space occupied by the device; The device can withstand large loads.

Finally, it should be noted that the above embodiments are only used to illustrate the technical solutions of the utility model without limitation. Although the utility model has been described in detail with reference to the preferred embodiments, those of ordinary skill in the art should understand that the utility model can be Modifications or equivalent replacements of the technical solutions of the new utility model without departing from the spirit and scope of the technical solutions of the utility model shall be covered by the claims of the utility model.
