Abstract

The invention discloses a foldable support which comprises a limit rod, a first movable support and a second movable support, wherein the first movable support and the second movable support are connected movably in a cross mode. A base plate is arranged at the top end of each movable support, a sliding track is arranged on two sides of the top end of the first movable support respectively, the cross section of each sliding track is in a shape of a reversed U, and symmetrical barb-shaped sliding track grooves are formed in the inner lateral side and the outer lateral side of each sliding track. One end of the limit rod is connected with limit angle iron, and the other end of the limit rod is inserted into a spring and penetrates the base plates to be connected with a first handle knob. Screws are arranged in the sliding track grooves. By pulling the limit rod to drive the limit angle iron to rotate around a connecting pin, different positions of the screws in the sliding track grooves are adjusted, and an effect that the support can conduct supporting and be folded back and forth is achieved. The foldable support is compact in structure and convenient to operate, can save storage space, enables users to adjust the height according to external conditions, improves working flexibility and is favorable for popularization, production and use.

Described position-limited lever is connected with an end of spacing angle bar by lock screw and to the locking of spacing angle bar, spacing angle bar also with insert slide rail in connecting pin is connected and is an axle rotation with the connecting pin.

Described screw comprises head, axial region and screw section, and described screw section is riveted on first travel(l)ing rest, and axial region is stuck in the sliding-rail groove, the sliding-rail groove of head exposing inside thereof face.

Described second travel(l)ing rest is provided with limiting board, and position-limited lever is provided with the position limit pin suitable with limiting board.

Described spacing angle bar be shaped as circular arc.

Four drift angle places on described chassis are provided with beam respectively, and chassis side is provided with handle.

Among the present invention, slide rail and chassis weld together, and are an integral body.Also be provided with second among the present invention and handle knob, second handles knob at the opposite side of slide rail, and screw is riveted on first travel(l)ing rest.When folding bracket reached certain working state, locking second was handled knob, and first travel(l)ing rest is slided.

Beneficial effect: a kind of folding bracket of the present invention, be provided with the slide rail of sliding-rail groove respectively in the travel(l)ing rest both sides, driving spacing angle bar by the pulling position-limited lever rotates around connecting pin, the diverse location of adjusting screw in sliding-rail groove, thereby can make support reach the effect that supports back and forth and fold, compared with prior art, compact structure of the present invention is easy to operate, take in the convenient parking space of saving, also can adjust the height of support according to external conditions such as heights, increase the flexibility of work largely, be conducive to promote produce and use.

Embodiment

Below in conjunction with accompanying drawing the present invention is done further explanation.

Shown in Fig. 1 to 5, a kind of folding bracket of the present invention, comprise first travel(l)ing rest 1 and second travel(l)ing rest 2 that position-limited lever 6, intersection flexibly connect, the top of two travel(l)ing rests is equipped with chassis 3, both sides, first travel(l)ing rest, 1 top are respectively equipped with slide rail 4, the cross section of described slide rail 4 is inverted U, and the inner side surface of slide rail 4 and outer side surface are provided with the barb type sliding-rail groove of symmetry, and sliding-rail groove comprises slide rail top 17, slide rail afterbody 16 and slide rail end 18; Described position-limited lever 6 one ends are connected with spacing angle bar 5, and position-limited lever 6 the other ends insert spring 11 and pass 3 backs, chassis and first handles knob and 7 be connected; Be provided with screw 20 in the sliding-rail groove.

In the present embodiment, position-limited lever 6 is connected with an end of spacing angle bar 5 by lock screw 10 and to spacing angle bar 5 lockings, spacing angle bar 5 also with insert slide rail 4 in connecting pin 9 be connected and serve as a rotation with connecting pin 9.Screw 20 comprises head, axial region and screw section, and the screw section is riveted on first travel(l)ing rest 1, and axial region is stuck in the sliding-rail groove, the sliding-rail groove of head exposing inside thereof face.Second travel(l)ing rest 2 is provided with limiting board 13, and position-limited lever 6 is provided with the position limit pin 14 suitable with limiting board 13.Spacing angle bar 5 be shaped as circular arc.Four drift angle places on chassis 3 are provided with beam 15 respectively, and 3 sides, chassis are provided with handle 12.

The present invention is in working order the time, screw 20 is in slide rail top 17, for preventing that screw 20 from skidding off from slide rail top 17, the spacing angle bar 5 of being furnished with arcuation herein, in any case to guarantee to move back and forth chassis 3, screw 20 can not slide into slide rail afterbody 16 from slide rail top 17, handles knob this moment second 8 to be in locking state.

As shown in Figure 2, when needs fold this support, unclamp second and handle knob 8, foot-operated second travel(l)ing rest 2, pull handle 12 makes screw 20 leave slide rail top 17 and arrives slide rail end 18, and spur first and handle knob 7 this moment, under the effect of spring 11, position-limited lever 6 is slowly mobile towards slide rail afterbody 16, and under the effect of position-limited lever 6, spacing angle bar 5 and then rotates around connecting pin 9, arrive position shown in Figure 2, this moment, screw 20 can slide into the outer arc face of spacing angle bar 5 from slide rail end 18.

As shown in Figure 3 and Figure 4, under the effect of power, position limit pin 14 slides into the following locating face of limiting board 13 under the circular arc of limiting board 13, and support folding back locking second handles knob 8.

When the support after needs will fold is opened to working state, only needs that above-mentioned steps is carried out repetitive operation by order from top to bottom and get final product.

It below only is preferred implementation of the present invention; be noted that for those skilled in the art; under the prerequisite that does not break away from the principle of the invention, can also make some improvements and modifications, these improvements and modifications also should be considered as protection scope of the present invention.
