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.

Summary of the invention
Goal of the invention: in order to overcome the deficiencies in the prior art, the present invention proposes a kind of folding bracket.
Technological scheme: for solving the problems of the technologies described above, a kind of folding bracket of the present invention, comprise position-limited lever, intersect be flexibly connected the first travel(l)ing rest and the second travel(l)ing rest, the top of two travel(l)ing rests is provided with chassis, first both sides, travel(l)ing rest top is respectively equipped with slide rail, the cross section of described slide rail is inverted U, and the inner side surface of slide rail and outer side surface are provided with symmetrical barb type sliding-rail groove; Described position-limited lever one end is connected with spacing angle bar, and the position-limited lever the other end inserts spring and is connected with the first knob after passing chassis; Screw is provided with in sliding-rail groove.
Described position-limited lever to be connected with one end of spacing angle bar by lock screw and to lock spacing angle bar, and spacing angle bar is also connected with the connecting pin inserted in slide rail and is that axle rotates with connecting pin.
Described screw comprises head, axle portion and screw section, and described screw section is riveted on the first travel(l)ing rest, and axle portion is stuck in sliding-rail groove, the sliding-rail groove in 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.
The shape of described spacing angle bar is circular arc.
Four drift angle places on described chassis are respectively equipped with beam, and chassis side is provided with handle.
In the present invention, slide rail and chassis weld together, and are an entirety.Also be provided with the second knob in the present invention, the second knob is at the opposite side of slide rail, and screw is riveted on the first travel(l)ing rest.When folding bracket reaches certain working state, lock the second knob, do not make the first travel(l)ing rest slide.
Beneficial effect: a kind of folding bracket of the present invention, the slide rail of sliding-rail groove is provided with respectively in travel(l)ing rest both sides, spacing angle bar is driven to rotate around connecting pin by pulling position-limited lever, the diverse location of adjusting screw in sliding-rail groove, thus support can be made to reach the effect supporting back and forth and fold, compared with prior art, compact structure of the present invention is easy to operate, storage conveniently saves parking space, the height of adjusting pole also can be carried out according to external conditions such as heights, increase the flexibility of work largely, be conducive to promoting production and application.

Embodiment
Below in conjunction with accompanying drawing, the present invention is further described.
As shown in Fig. 1 to 5, a kind of folding bracket of the present invention, comprise the first travel(l)ing rest 1 and the second travel(l)ing rest 2 of position-limited lever 6, intersection flexible connection, the top of two travel(l)ing rests is provided with chassis 3, first both sides, travel(l)ing rest 1 top is 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 symmetrical barb type sliding-rail groove, and sliding-rail groove comprises slide rail top 17, slide rail afterbody 16 and extreme 18; Described position-limited lever 6 one end is connected with spacing angle bar 5, and position-limited lever 6 the other end inserts spring 11 and is connected with the first knob 7 after passing chassis 3; Screw 20 is provided with in sliding-rail groove.
In the present embodiment, position-limited lever 6 to be connected with one end of spacing angle bar 5 by lock screw 10 and to lock spacing angle bar 5, and spacing angle bar 5 is also connected with the connecting pin 9 inserted in slide rail 4 and with connecting pin 9 for axle rotates.Screw 20 comprises head, axle portion and screw section, and screw section is riveted on the first travel(l)ing rest 1, and axle portion is stuck in sliding-rail groove, the sliding-rail groove in 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.The shape of spacing angle bar 5 is circular arc.Four drift angle places on chassis 3 are respectively equipped with beam 15, and side, chassis 3 is provided with handle 12.
The present invention in working order time, screw 20 is in slide rail top 17, skid off from slide rail top 17 for preventing screw 20, is furnished with the spacing angle bar 5 of arcuation herein, in any case to guarantee to move back and forth chassis 3, screw 20 all can not slide into slide rail afterbody 16 from slide rail top 17, and now the second knob 8 is in locking state.
