Description
The utility model relates to a kind of ladder, used photography ladder during particularly criminal case crime scene is reconnoitred.
In criminal case crime scene is reconnoitred, leave the tracers of a crime material evidence on the object of on-the-spot eminence (more than work ground 1.7m), fix, extract needs with the method for taking pictures and solve the instrument of ascending a height, camera is fixed, shooting distance, the selection of angle, how lighting and staff the problem of five aspects such as operate.At present, abroad when floor eminence vestige, take to land tripod (tripod can raise more than the 2m) more, set up camera, the staff operates on the platform that other takes.This type of on-the-spot trace evidence of domestic shooting is that tables and chairs are scrabbled up a workbench, and tripod is placed on the platform, and camera is fixed on the tripod, staff's cloth optical illumination, and another staff's operate camera is taken.Bring insoluble problem for like this shooting, extraction work.The one, take orientation problem, want to obtain good shooting effect, just must choose shooting distance and shooting angle.Therefore it is just very necessary to adjust tripod workbench position repeatedly, but this adjustment ten minutes trouble is influenced by site environment sometimes, and the area and the position of workbench all are restricted, and is that comparison is because of difficulty so will reach satisfied shooting location.The 2nd, field condition is taken problem, and take and extract the vestige that the offender is retained in field condition eminence (first-class as residual wall, electric pole, tree), the instrument of also not ascending a height at present, it is also inconvenient to remove tables and chairs, even there is the ladder also can't fixed camera.So this class shooting extracts vestige, is an insoluble problem.
The purpose of this utility model is exactly in order to address the above problem, and provides a kind of easy to adjust, adapts to various occasions and uses, and not only have the effect of tripod fixed camera but also have the portable multi-function photography ladder of ascending a height and acting on.
Technical solution of the present utility model:
A kind of portable multi-function photography ladder; it is characterized in that it is by ladder (1); rotary working platform (2) and camera support (3) are formed; ladder (1) is three liftable supporting legs; wherein have at least one to be the lifting landing leg of ladder structure (4); rotary working platform (2) is by fixed head (5); rotor plate (6) and protection railing (7) are formed; connect for two-dimensional activity between fixed head (5) and the rotor plate (6); fixedly connected with fixed head (5) in the upper end of ladder (1); protection railing (7) is fixedlyed connected with rotor plate (6); camera support (3) is made up of horizontal brace rod (8) and photography bar (9); horizontal brace rod (8) is a rack bar; it is positioned at the teeth groove of rotor plate (6) bottom surface and is engaged with connection; the position near protection railing (7) of horizontal brace rod (8) is provided with pedal wheel (10); to regulate the flexible of horizontal brace rod (8); the front end of horizontal brace rod (8) connects as one by universal structure with the lower end of photography bar (9); make that photography bar (9) can be that fulcrum carries out omnibearing rotation and regulates with its tie point with horizontal brace rod (8), photography bar (9) upper end is passed through camera fixing device (11) and is connected with camera (12).
The utility model has solved the shooting of on-the-spot trace evidence and has extracted a difficult problem, and it can be used as tripod again and use as the ascend operation instrument, so make in the site inspection " comprehensive " the extraction vestige of taking a picture become possibility.The utility model sets up conveniently, and stable strong is durable, and is easy to operate, adjust easily, applied range, its function is many, carry easily, can replace on-the-spot each the position trace evidence of the comprehensive shooting indoor and outdoor of tripod, can raise again is used for on-the-spot orientation, general picture and keypoint part photograph.Need piece together the behindhand type that tables and chairs are set up the stage and taken pictures thereby change in the past on-the-spot eminence trace evidence, and particularly solve no commanding elevation, large-scale scene, the outdoor level land little difficulty of depth scope of taking pictures, in the practical application of case, effect is very good.The utility model also can be used as the ascend operation instrument of TV, news, construction sector.
Fig. 1 is a structural representation of the present utility model.
As Fig. 1, in the utility model, fixedly connected with the outer rim relevant position of fixed head (5) in the rotary working platform (2) in three supporting leg upper ends of ladder (1), fixed head (5) center is connected with central shaft (13) downwards, ladder (1) three supporting leg top is connected on the sleeve pipe (15) by connecting link (14) separately, this sleeve pipe (15) is sleeved on the central shaft (13), and by its set screw adjusting, make ladder (1) three supporting leg can slide up and down along central shaft (13), regulate the opening angle of three supporting legs by connecting link (14).Can realize that two-dimensional activity connects by ball and corresponding ball grooves structure thereof between the fixed head (5) of rotary working platform (2) and the rotor plate (6).The photography bar (9) of camera support (3) also is an expansion link; and be connected with lamp bracket (16) on its top expansion link; so that install photography luminaire (17); photography bar (9) is gone up activity and is connected with liftable stable support bar (18); it is two telescopic outriggers; and activity is connected with telescopic auxiliary rod (19) between the protection railing (7) of stable support bar (18) upper end and rotary working platform (2), to guarantee the job stability of photography bar (9) when transferring to the optional position.
During the utility model work, regulate the height and the opening angle of ladder (1) and fix the ungulate slab construction of foot of ladder employing universal type, promptly anti-skidding anti-again falling into according to field condition and on-the-spot vestige.The staff goes up to worktable (2) by the supporting leg (4) of the ladder structure of ladder (1), and workbench (2) can carry out 360 degree and smoothly tune, and utilizes the knob of protection railing (7) as rotary working platform (2) dexterously.So in a single day, set up ladder (1), the angular setting of horizontal direction just need not mobile ladder (1), and rotation work platform (2) is finished easily.Be provided with the horizontal brace rod (8) of camera support (3) in the workbench (2), they adopt the gearing mesh structure to connect, it is pedal wheel (10) on the available pin operant level connecting link (8) that the operator need not bend over, and comes the flexible of controlling level connecting link (8), not only handled easily but also reduce danger.The photography bar (9) that horizontal brace rod (8) is connected has " comprehensive " characteristics, adopts 720 degree stepless tuning, and its locking adopts the taper mode to lock.The utility model causes camera-shake for avoiding time exposure, influences shooting effect, is provided with liftable stable support bar (18), in order to guarantee the stable of photography bar (9).Ladder of the present utility model (1) is folding with workbench (2) employing and separate loading and unloading type, makes to be easy to carry smaller volume.
