Description

The spacing pivot device of a kind of wide-angle

Technical field

The utility model relates to a kind of pivot device that is applicable to electronic product, relates in particular to a kind of spacing pivot device structure of wide-angle with the spacing rotation of multistage.

Background technique

In recent years, popular digital camera or the digital cameras etc. of utilizing are shot with video-corder the picture device, record is travelled outdoors or the static image or the dynamic image of ceremony that other are important or deed (as: wedding, concert etc.), again in conjunction with the mode of picture and text explanations, will be at that time situation noted fully as diary, even be used for being distributed on (as: blogger or personal travel diary etc.) on the Internet; But; because traditional digital camera or digital camera; its camera lens and screen are one and can't adjust relative angle; often have the dead angle between camera lens and reference object and can't take; therefore, present most digital camera or digital camera, but between screen and body, can be provided with twin shaft to the pivot that rotates; make screen make disalignment to reaching rotating of angle, be convenient to the usefulness that the user takes or views and admires relative to body.

Is example with general twin shaft to pivot device, sees also shown in Figure 1ly, and its pivot device 1 comprises one first support 11, one second support 12, one first spacing group 13 and an axostylus axostyle 14; Wherein, described first support 11 slightly is the U font, and is provided with a perforation 111 at central part, and described perforation 111 peripheries are provided with a stopper part 112, and described first support 11 is fixedly arranged on the body (not shown); Described second support 12 is fixedly arranged on the screen (not shown), and central part is provided with an axis hole 121; Be located at described first support, 11 1 sides for described first spacing group 13, make described body and described first support 11 can carry out the first axial spacing rotation; Described axostylus axostyle 14 then is arranged in the axis hole 121 and an elastic element 15 of the perforation 111 of described first support 11, described second support 12 in regular turn, utilize a fixed block 16 to be fixed at last again, make described second support 12 and described axostylus axostyle 14 form one, and described first support 11 can be done another axial rotating relative to described second support 12, described axostylus axostyle 14 tops also are provided with a ring flange 141, and the periphery of described ring flange 141 is provided with a limited part 142; In view of the above, axostylus axostyle 14 is arranged in perforation 111 back of first support 11 and can not comes off, and the limited part 142 by axostylus axostyle 14 and the stopper part 112 of first support 11 be clip mutually, and makes screen do second axial spacing the rotation relative to body.

Yet, because the limit structure that first support 11 and axostylus axostyle are 14 design, as: the size of stopper part 112 and limited part 142, volume all must can provide enough intensity, so design of this class limit structure, only can provide pivot device 1 to make the spacing rotation angle of maximum 270 degree, the scope of this spacing rotation angle, can be disperseed again in use as the angle of just changeing and reversing, for example: just turning 90 degrees and adding anti-turnback, because the angle limits of this spacing rotation, also cause the restriction of designer when design electronic products relatively, therefore also have the place of functional deficiency.

So this creator accumulates design pivot device experience for many years, but design the pivot device structure of the spacing rotation of a kind of wide-angle especially, and also can reach the spacing rotation that surpasses 360 degree under suitable condition.

Summary of the invention

Main purpose of the present utility model is to provide a kind of pivot device that carries out wide-angle (greater than 270 degree) limit effect, can significantly promote the convenience when using, and electronic product is functional.

For reaching above-mentioned purpose, the utility model comprises at least: one first support, at least one limited ring, an axostylus axostyle and one second support; Wherein, the described first support central authorities are provided with a circular hole, and described circular hole periphery is provided with limited ring groove, and the barricade of described limited ring groove is provided with a notch part; Described limited ring activity is located in the limited ring groove of first support, and the periphery of described limited ring and wherein respectively convex with a stopper part on the one side is located in the notch part stopper part of described limited ring periphery, and in addition described limited ring central authorities are provided with a perforation; Described axostylus axostyle activity is located in the perforation at described limited ring center, and described axle end is provided with the ring flange of protrusion, and described ring flange is provided with a stopper part, and the stopper part of described axostylus axostyle is relative with the stopper part of described limited ring; And the described second support central authorities are provided with an axis hole, and the below is provided with elastic element and fixed block.

In view of the above, because limited ring is to limit sliding chutes, big than axostylus axostyle protuberance and stopper part to the frictional force of limited ring, when first support when second support rotates, the axostylus axostyle and second support are stationary state, and limited ring can be done first section rotation synchronously with first support, until the stopper part on limited ring surface by the stopper part of axostylus axostyle institute clip, then, but the first support relative limit ring rotates, notch part clip until the limited annular groove in the stopper part of limited ring periphery, form the spacing rotation of multi-section type, finishing spacing rotation, the wide-angle limit effect can't be arranged and cause inconvenience in the use, the utility model significantly to promote the convenience that uses compared to existing greater than 270 degree; But the structural design that wide-angle described in the utility model is spacing also provides bigger design allowance, provides the designer to design and has multi-purpose electronic product.
