Abstract

The utility model discloses a tripod with a swinging center shaft, which comprises a body component, a center shaft, support legs, a center shaft sleeve and a knob. An expansion copper ring, a first lock ring, a second lock ring, a screw ring, a first fixing ring and a second fixing ring are disposed sequentially outside the center shaft. The knob includes a screw cap, a conical copper sleeve and a screw rod, the conical copper sleeve is positioned at an oblique notch of the expansion copper ring, the screw rod is screwed through the through threaded hole of the center shaft sleeve from inside to outside, penetrates through the oblique notch of the expansion copper ring, the conical copper sleeve, an upper groove of the first lock ring, a notch of the second lock ring, a lower groove of the first fixing ring and a lower groove of the second fixing ring, and is the screwed on the screw cap. The center shaft of the tripod can swing back and forth and left and right under driving of the center shaft sleeve, and thereby a camera can be placed horizontally and easily on the uneven ground by adjusting the support legs of the tripod and then adjusting verticality of the swinging center shaft.

Description

Has the tripod that can wave axis

Technical field

The utility model relates to the photographic goods technical field, relates in particular to a kind of tripod that can wave axis that has.

Background technique

In the camera work field, tripod is used for the stable support photographic camera, to reach photographic effects preferably.The structure of tripod generally includes body assembly, be plugged in the axis on the described body assembly and be connected three supporting legs on the described body assembly.

During practical application, for photographic camera is horizontal, the length that needs the supporting leg of free adjusting tripod, yet when running into occasions such as open air, because ground out-of-flatness, the difficulty that can increase regulate, in any case and may regulate and all be difficult to make photographic camera be in substantially horizontal position, thereby photographic effects influenced.

The model utility content

The purpose of this utility model provides a kind of tripod that can wave axis that has, and it can easily make photographic camera be horizontal.

For achieving the above object, the utility model adopts following technological scheme:

A kind of have a tripod that can wave axis, comprises body assembly, is plugged in the axis on the described body assembly and is connected three supporting legs on the described body assembly, also comprises Intermediate shaft sleeve and knob, wherein,

Described Intermediate shaft sleeve is positioned at the top of described body assembly and is socketed on the described axis; Described Intermediate shaft sleeve outside is disposed with expansion copper band, first clamp ring, second clamp ring, screws circle, first retainer ring and second retainer ring;

Described expansion copper band is provided with the oblique angle gap, and described first clamp ring is provided with upper groove, and described second clamp ring is provided with gap, and described first retainer ring and second retainer ring are provided with low groove, and described Intermediate shaft sleeve is provided with penetrating tapped hole;

Described knob comprises turncap, taper copper sheathing and swing arm, described taper copper sheathing is positioned at the oblique angle opening position of described expansion copper band, described swing arm revolved the penetrating tapped hole of described Intermediate shaft sleeve from the inside to the outside, pass oblique angle gap, taper copper sheathing, the upper groove of first clamp ring and the gap of second clamp ring of expansion copper band, the low groove of first retainer ring, the low groove of second retainer ring, be spun at last on the described turncap.

Further, the inside and outside footpath of described first and second clamp rings is identical, and the external diameter of described expansion copper band equals the internal diameter of described first clamp ring.

Further, the outer surface of described first clamp ring and second clamp ring is combined into a part spherical surface, and the internal surface of described first retainer ring also is a part spherical surface, the equal diameters of this two spherical surface.

The utility model provides has the tripod that can wave axis, axis can be under the drive of Intermediate shaft sleeve roll and pitch, like this when the out-of-flatness of ground, can regulate the supporting leg of tripod earlier, and then by regulating the perpendicularity that to wave axis, finally just can photographic camera be horizontal, thereby guarantee photographic effects.

Embodiment

In order to make the purpose of this utility model, technological scheme and advantage clearer,, the utility model is further elaborated below in conjunction with drawings and Examples.Should be appreciated that specific embodiment described herein only in order to explanation the utility model, and be not used in qualification the utility model.

As Figure 1-3, the utility model provides a kind of tripod that can wave axis that has, and comprises body assembly 9, is plugged in the axis 1 on the body assembly 9 and is connected three supporting legs on the body assembly 9, and it also comprises Intermediate shaft sleeve 8 and knob, wherein:

Intermediate shaft sleeve 8 is positioned at the top of body assembly 9 and is socketed on the axis 1; Intermediate shaft sleeve 8 outsides are disposed with expansion copper band 4, first clamp ring 3, second clamp ring 5, screw circle 2, first retainer ring 6 and second retainer ring 7;

Expansion copper band 4 is provided with the oblique angle gap, and first clamp ring 3 is provided with upper groove, and second clamp ring 5 is provided with gap, and first retainer ring 6 and second retainer ring 7 are provided with low groove, and Intermediate shaft sleeve 8 is provided with penetrating tapped hole;

Knob comprises turncap 12, taper copper sheathing 11 and swing arm 10, taper copper sheathing 11 is positioned at the oblique angle opening position of expansion copper band 4, swing arm 10 revolved the penetrating tapped hole of Intermediate shaft sleeve 8 from the inside to the outside, pass oblique angle gap, taper copper sheathing 11, the upper groove of first clamp ring 3 and the gap of second clamp ring 5 of expansion copper band 4, the low groove of first retainer ring 6, the low groove of second retainer ring 7, be spun at last on the turncap 12.

Of the present utility model have a tripod that can wave axis, axis and Intermediate shaft sleeve 8, expansion copper band 4, first clamp ring 3, second clamp ring 5 and screw circle 2 and be connected and be one, the part spherical surface of the outer surface by first and second clamp ring 3,5, contact with the part spherical surface of the internal surface of first retainer ring 6, arbitrarily angled rotary oscillation in first retainer ring 6 is realized waving of axis.When the out-of-flatness of ground, can regulate the supporting leg of tripod earlier like this, and then, finally just can photographic camera is horizontal, thereby guarantee photographic effects by regulating the perpendicularity that to wave axis.

In the utility model, the taper copper sheathing 11 that is provided with on the swing arm 10 is positioned at the oblique angle opening position of expansion copper band 4.When knob 12 turns clockwise, taper copper sheathing 11 is advanced to the Intermediate shaft sleeve center, the conical surface of taper copper sheathing 11 contacts with the oblique angle gap of expansion copper band 4, make gap become big, thereby expansion copper band 4 is expanded, and then make and its contacted first and second clamp ring 3,5 expansion, increase the frictional force between first and second clamp ring 3,5 and first retainer ring 6, reach the purpose of locking, realize that axis is rocked to the arbitrary position and can both be locked.

In addition, in the tripod shown in Figure 1, the inside and outside footpath of first, second clamp ring 3,5 is identical, and the external diameter of expansion copper band 4 equals the internal diameter of first clamp ring 3.Simultaneously, the outer surface of first clamp ring 3 and second clamp ring 5 is combined into a part spherical surface, and the internal surface of first retainer ring 6 also is a part spherical surface, the equal diameters of this two spherical surface.

The above is preferred embodiment of the present utility model only, is not to be used for limiting practical range of the present utility model; If do not break away from spirit and scope of the present utility model, the utility model is made amendment or is equal to replacement, all should be encompassed in the middle of the protection domain of the utility model claim.
