Description

A temporary outrigger for long-span furniture

technical field

The utility model relates to the field of furniture, in particular to a temporary support leg of large-span furniture.

Background technique

At present, most of the furniture on the market is a fixed support frame. When encountering a large-span furniture that needs to be folded and contracted, the fixed support frame cannot meet this feature. For example, there is no support in the middle of a long-span table, which leads to low strength and easy deformation of this part, which reduces the bearing capacity. Therefore, a temporary support structure is needed to strengthen the weak part in the middle.

Contents of the invention

The purpose of this utility model is to solve the deficiency of the above-mentioned background technology, and provide a temporary support leg for large-span furniture.

The technical scheme of the utility model is: a temporary support leg for large-span furniture, which is characterized in that it includes a fixed arm and a rotating leg, the rotating leg is connected to the fixed arm at the lower end of the fixed arm, and the rotating leg It includes a horizontal bar and a vertical bar connected under the horizontal bar. The lower end of the vertical bar is equipped with an adjustable outrigger seat, and the rotating outrigger is provided with a supporting reinforcement device.

Preferably, a protruding rotating shaft is provided at the end of the rotating leg, and the lower end of the fixed arm is sleeved on the rotating shaft.

Preferably, the support reinforcement device includes a reinforcing rod hinged to the transverse rod, and the upper surface of the transverse rod is provided with a strip-shaped groove corresponding to the reinforcing rod, and the strip-shaped groove is vertically arranged in the longitudinal direction of the transverse rod. A through groove corresponding to the cross-section of the stiffener.

Further, the screw passes through the transverse bar from bottom to top to hinge the reinforcing bar and the transverse bar.

Furthermore, a positioning spring is provided between the screw end and the transverse rod.

Preferably, the adjustable outrigger seat is threadedly connected with the vertical rod.

Preferably, a fixing hole is opened at the upper end of the fixing arm.

Further, the fixing hole is circular or long.

In the utility model, the fixed arm is fixedly hinged with the side wall of the supported object, the rotating outrigger is rotated to the bottom of the supported object, and the adjustable outrigger seat is adjusted so that the height of the vertical rod changes until the horizontal rod of the rotating outrigger and the horizontal rod of the rotating outrigger The lower surface of the supported object is in close contact, and the rotating outrigger can also rotate and adjust the supporting position according to the force change of the supported object. In the support strengthening device, when the reinforcing rod is lifted and rotated to the through groove, it forms a cross structure with the transverse rod to increase the supporting area.

The utility model has the advantages of simple structure and convenient use, and can effectively support the large-span and folded and contracted furniture at the bottom to avoid deformation and fracture of the furniture and increase the service life of the furniture.

Detailed ways

Below in conjunction with accompanying drawing and specific embodiment the utility model is described in further detail.

As shown in Figure 1-3, the temporary outrigger includes a fixed arm 1 and a rotating outrigger 2. The rotating outrigger 2 includes a horizontal rod 3 and a vertical rod 4 connected under one end of the horizontal rod 3. The other end of the rotating outrigger 2 is provided with a There is a raised rotating shaft 6; the upper end of the fixed arm 1 is provided with a circular or elongated fixing hole 12, and the lower end is sleeved on the rotating shaft 6 and connected to the transverse bar 3 in rotation. The transverse bar 3 on the rotating leg 2 is provided with a supporting strengthening device, including a reinforcing bar 7 hinged with the transverse bar 3, and the upper surface of the transverse bar 3 is provided with a bar-shaped groove 8 corresponding to the reinforcing bar 7, and the bar-shaped groove A through groove 9 corresponding to the cross-section of the reinforcing rod 7 is provided in the inner portion 8 perpendicular to the length direction of the transverse rod 3 . A vertical through hole is arranged on the transverse bar, and the diameter of the through hole is slightly larger than the diameter of the screw 10. The reinforcing bar 7 is hinged with the transverse bar 3 by the screw 10 passing through the through hole on the transverse bar 3 from bottom to top, and the screw 10 ends After the part enters the reinforcing rod 7, the reinforcing rod 7 can be moved up and down within a certain range, and a positioning spring 11 is arranged between the end of the screw 10 and the transverse rod 3.

The adjustable outrigger seat 5 is threadedly connected with the vertical bar 4. In the present embodiment, the adjustable outrigger seat 5 is a hexagonal bolt, and the lower end of the vertical bar 4 has a screw hole matched with the hexagonal bolt.

When using temporary legs, the fixed arm 1 is fixed and hinged with the side wall of the supported object through the fixing hole 12, the reinforcing rod 7 is lifted, and rotated into the through groove 9. At this time, the reinforcing rod 7 and the transverse rod 3 are cross-shaped and the surface The surface of the horizontal rod 3 is on the same plane, rotate the leg 2 to the bottom of the supported object, and rotate the adjustable leg seat 5 to make the height of the vertical rod 4 change until the horizontal rod 3 of the rotating leg 2 is under the supported object. The surface is tight. According to the force change of the supported object, the outrigger 2 can be rotated to adjust the supporting position. The temporary outriggers can effectively support the large-span and folded and contracted furniture below, avoiding deformation and breakage, and increasing the service life of the furniture.

The above is only a specific embodiment of the present utility model. It should be pointed out that any changes or replacements that can be easily imagined by those skilled in the art within the technical scope disclosed in the present utility model should be covered by the present utility model. within the scope of protection.
