[specific embodiment]

Below in conjunction with accompanying drawing, specific embodiments of the invention is described in detail.

Fig. 1 is the structural representation of tripod supporting construction 10 among the embodiment, and Fig. 2 is the axial, cross-sectional view at tripod supporting construction 10 retainer rings shown in Figure 1 200 places, and Fig. 3 is the axial, cross-sectional view at tripod supporting construction 10 loose collars shown in Figure 1 400 places.In conjunction with Fig. 1 to Fig. 3, this tripod supporting construction 10 comprises: slide bar 100, retainer ring 200, feet 300, loose collar 400, gangbar 500 and locating part 600.

Slide bar 100 is the slide bar of hollow, offers a plurality of spacing holes 110 on its outer peripheral face.A plurality of spacing holes 110 are along slide bar 100 axial distribution, are on the same straight line with axially parallel.

Retainer ring 200 fixed covers are located at slide bar 100 bottoms (when tripod supporting construction 10 was supported on ground, slide bar 100 was near an end on ground), are used to assemble feet 300.Among this embodiment, in the retainer ring 200 damped ring 700 is housed week, is used to compensate the assembling space between retainer ring 200 and the slide bar 100.Retainer ring 200 adopts holding screws 210 locking damped rings 700 slide bar 100 that is locked, and is fixed on slide bar 100 bottoms.

Feet 300 is rotatably connected with retainer ring 200, is used to strut on ground, and whole tripod supporting construction 10 is supported.Among this embodiment, feet 300 is three, evenly be installed on the retainer ring 200 along retainer ring 200 circumference, and hinged through bearing pin 800 with split pin 900 and retainer ring 200.Feet 300 rotates around bearing pin 800.The end that feet 300 contacts with ground is equipped with slipmat 310, and slipmat 310 is used for when feet 300 is supported on ground, skidding.

Loose collar 400 is set on the slide bar 100 slidably, along slide bar 100 axially-movables.Be the assembling space between compensation slip ring 400 and the slide bar 100, damped ring 700 is housed in the slip ring 400 in week.

Gangbar 500 and loose collar 400 all are rotatably connected with feet 200, when loose collar 400 motions, drive feet 200 and strut or draw in, the angle of adjustment feet 200 and slide bar 100.Among this embodiment, gangbar 500 is all carried out hinged through bearing pin 800 and split pin 900 with loose collar 400 and feet 200.Gangbar 500 is rotated around bearing pin 800.

Locating part 600 is used to limit the position of loose collar 400 on slide bar 100, limits the angle between feet 200 and the slide bar 100.Among this embodiment, locating part 600 is the spacer pin adaptive with spacing hole 110.After inserting in the spacing hole 110, spacer pin can effectively prevent loose collar 400 motions.Simultaneously, lose for preventing locating part 600, locating part 600 has chain 610, and chain 610 two ends are connected with locating part 600 with loose collar 400 respectively, locating part 600 are fastened be connected on the loose collar 400.

Fig. 4 is that tripod supporting construction 10 shown in Figure 1 is drawn sketch map in.This tripod supporting construction 10, in the time need not supporting to light fixture, the position of adjustment loose collar 400 on slide bar 100; Make that feet 300 is oppositely parallel with slide bar 100 (also can adjust the position of loose collar 400 on slide bar 100; Make feet 300 forwards parallel with slide bar 100), gangbar 500 is with parallel with slide bar 100 simultaneously, thereby tripod supporting construction 10 is drawn in fully; Take less space, be convenient for carrying.When needs support light fixture, the position of loose collar 400 on slide bar 100, gangbar 500 is followed loose collar 400 motions, and pulling feet 300, makes three feets 300 strut certain angle, and the formation triangle is stable to be stood on the ground.Adjust the position of loose collar 400 as required; The angle of control feet 300 and slide bar 100; Make tripod remain on required height, then locating part 600 is inserted in the spacing hole 110, restraint ring 400 is to moving away from slide bar 100 bottom directions; Thereby the support that makes tripod supporting construction 10 firm, stable on the ground, and keep certain height light fixture is supported.After finishing using, locating part 600 to be extracted, loose collar 400 draws tripod supporting construction 10 fully in to the motion of slide bar 100 bottoms and gets final product; Simple light is easy to carry, single can the operation; Need not auxiliary equipment carry; Can adapt to different orographic conditions, reliability is high, has certain wind loading rating.Be applicable to various field construction operations, safeguard working sites such as repairing, accident treatment and rescue and relief work, also can be satisfied with being used in long distance, the interim needs of installing in high brightness floodlight fixture job site.

In other embodiments, can have enough height for guaranteeing this supporting construction, feet 300 can be stretching structure, can change length, also can when drawing in, further reduce taking up room.

Locating part 600 is for running through the holding screw of loose collar 400, and holding screw locking damped ring 700 is held slide bar 100 tightly, and loose collar 400 is fixed on the slide bar 100, limits the position of loose collar 400.

Perhaps; Slide bar 100 peripheries have the slide bar screw thread, and loose collar 400 has first loose collar and second loose collar, and first loose collar and second loose collar can relatively rotate and all be set on the slide bar 100; The gangbar 500 and first loose collar are hinged; Have the qualification screw thread that matees with slide bar 100 periphery slide bar screw threads in second loose collar week, rotate second loose collar and regulate the position of loose collar 400 on slide bar, limit loose collar 400 positions through slide bar screw thread and qualification screw thread.

In addition, also provide a kind of like Fig. 5 and light fixture shown in Figure 6.This light fixture comprises lamp holder 30, lamp bracket 20 and above-mentioned tripod supporting construction 10.Lamp holder 30 is installed on the lamp bracket 20, and lamp bracket 20 is connected with tripod supporting construction 10.10 pairs of lamp holders of tripod supporting construction 30 carry out firm support.Lamp holder 30 can be as shown in Figure 5 one, also can be as shown in Figure 6 two.

The above embodiment has only expressed several kinds of embodiments of the present invention, and it describes comparatively concrete and detailed, but can not therefore be interpreted as the restriction to claim of the present invention.Should be pointed out that for the person of ordinary skill of the art under the prerequisite that does not break away from the present invention's design, can also make some distortion and improvement, these all belong to protection scope of the present invention.Therefore, the protection domain of patent of the present invention should be as the criterion with accompanying claims.
