Description

A kind of tripod

Technical field

The utility model relates to the photographic goods technical field, the tripod that especially a kind of photograph, shooting or video display lamp are used.

Background technique

The use of camera often will be used camera trivets, and tripod generally has three supporting legs to constitute, and every supporting leg is made up of some telescopic arms.Supporting leg to be opened when foot rest uses, should open suitable angle, it can not fallen down because of loading onto camera, particularly full length shot, regulate the arm of three supporting legs again and determine height.Add that tripod center of gravity behind the camera on the top of tripod, is easy to fall down the damage camera because of slight external force, very big being not easy to again of weight moved simultaneously, loses the inning of shooting easily.

The model utility content

First purpose of the present invention is that to solve existing camera trivets center of gravity higher, realizes that the technological scheme that this purpose adopts is:, a kind of tripod, comprise axis, tripod main body, pull bar, leg, compress disk, round base and fixed component.

Wherein the diameter of the bottom of axis is relatively large, has outside thread in diameter major part, and axis passes the tripod main body and compresses disk and is fixed on the pedestal.

Wherein outside thread and axis are integrally formed, perhaps are formed separately then to combine.

Wherein compress disk and have internal thread and breach, match with outside thread by internal thread.

Wherein leg is linked on the pedestal versatilely, and every leg is movably attached on the tripod main body by pull bar.

Wherein the tripod main body has a fixed component, is used for the tripod main body is fixed on axis 1, and fixed component is bolt or other fixing devices.

Wherein, the tripod main body can be free to slide on axis.

When needs are packed up leg, by rotatably compressing disk, make breach overlap with leg, just can drive pull bar pull-up leg along the axis tripod main body of upwards sliding then, finish the action of gathering.

When needs get out leg, by rotatably compressing disk, make breach overlap with leg, just can drive pull bar along middle stern tube to lower slider tripod main body and get out leg, when leg put down put in place after, rotatably compress disk then and make breach avoid leg can to push down three legs, thereby fixed feet, rotate the secure component on the tripod main body at last, thereby fix pull bar, can finish the action that gets out of tripod.

The beneficial effects of the utility model are, only need slip tripod main body can finish the folding and unfolding work of tripod, and the weight of three legs and pedestal reduces the center of gravity of tripod, can lean on the light problem of falling down that moves and do not worry tripod of universal caster wheel.

As a further improvement on the present invention, axis can stretch, and is convenient to adjust the height of tripod like this.

Further improvement of the present invention is equipped with universal pulley below the outer end of leg, be convenient to conveniently moving like this.

The further improvement of the present invention part is that a base is equipped with in the axis upper end, is used for fixing camera, vidicon camera or video display lamp etc.

Another improvements of the present invention are that universal pulley is installed on the leg by a height-adjustable arm or spring, are convenient to like this move on the ground of injustice.

In addition, universal pulley has brake function, can fixed tripod slide when needs are not mobile.

Description of drawings

The utility model will illustrate by example and with reference to the mode of accompanying drawing, wherein:

Fig. 1 is tripod structure figure.

Fig. 2 is a tripod subelement sectional drawing.

Fig. 3 is axis and the sectional drawing that compresses disk.

Embodiment

Tripod as shown in Figure 1 comprises axis 1, tripod main body 2, pull bar 3, leg 4, compresses disk 5, round base 6, universal caster wheel 7 and fixed component 8.

The diameter of the bottom of axis 1 is relatively large, has outside thread 9 in diameter major part, and outside thread 9 can be integrally formed with axis 1, perhaps is formed separately then to combine.Axis 1 passes tripod main body 2 and compresses disk 5 and is fixed on the pedestal 6.Axis 1 can adopt welding, bolt or other constituted modes with the fixing of pedestal 6, and in concrete production process, they also can be integrally formed.

Compress disk 5 and have internal thread 10 and breach 11, match with outside thread 9, when needs get out leg, by rotatably compressing disk 5, thereby make breach 11 avoid leg 4 fixed feet 4, so that leg 4 can not packed up by internal thread 10; When needs are packed up leg,, make breach overlap, thereby can pack up leg with leg 4 by rotatably compressing disk 5.

Leg 4 is linked on the pedestal 6 versatilely, and every leg 4 is connected on the tripod main body 2 versatilely by pull bar 3.

Tripod main body 2 has a fixed component 8, is used for tripod main body 2 is fixed on axis 1, and fixed component can be bolt or other means of fixation.

When needs are packed up leg, by rotatably compressing disk 5, make breach overlap with leg 4, just can drive pull bar 3 pull-up legs 4 along the axis 1 tripod main body 2 of upwards sliding then, finish the action of gathering.

When needs get out leg, by rotatably compressing disk 5, make breach overlap with leg 4, just can drive pull bar 3 along middle stern tube 1 to lower slider tripod main body 2 and get out leg 4, when leg put down put in place after, rotatably compress disk 5 then and make breach 11 avoid leg 4 can to push down three legs, thereby fixed feet 4, rotate the secure component 8 on the tripod main body 2 at last, thereby fix pull bar 3, can finish the action that gets out of tripod.

Owing to only need slip tripod main body can finish the folding and unfolding work of tripod, the weight of three legs and pedestal reduces the center of gravity of tripod, can lean on the light problem of falling down that moves and do not worry tripod of universal caster wheel.

As a further improvement on the present invention, axis 1 is collapsible, so that can regulate the height of axis 1.

Another improvements of the present invention are that the bottom, outer end of leg 4 has universal caster wheel 7, so that conveniently moving.

Another improvements of the present invention are that a base 13 is equipped with in the axis upper end, is used for fixing camera, vidicon camera or video display lamp etc.

Another improvements of the present invention are that universal pulley 7 is installed on the leg 4 by a height-adjustable arm or spring 12, are convenient to like this move on the ground of injustice.

In addition, universal pulley 7 has brake function, can fixed tripod slide when needs are not mobile.

Tripod of the present invention can be applied to photograph, shooting or video display lamp etc.

Disclosed arbitrary feature in this specification (comprising any accessory claim, summary and accompanying drawing) is unless special narration all can be replaced by other equivalences or the alternative features with similar purpose.That is, unless special narration, each feature is an example in a series of equivalences or the similar characteristics.
