Abstract

The utility model discloses a free rotary support base, comprising a bracket and a mask which support the flat framework. The bracket supporting face is provided with an arch opening which is connected with an embedded element of the rotating shaft and the graduated dowel disc; the embedded element of the rotating shaft is connected with the graduated panel of the graduated dowel disc through the locating hole in the central bottom of the mask shell so as to drive the rotating shaft to rotate up and down at a direction is perpendicular to the vertical direction of the mask or to drive the graduated panel have a 360 degrees rotation centering on the bottom of the graduated dowel disc. The 360 degrees rotation of the utility model is simple in structure, and freely and conveniently enables the angle exchange and elevation adjustment of the products which are in fixed connection with the mask with a simple and convenient approach. The utility model facilitates the products of mask to change direction easily according to the need, and assures a flexible direction adjustment and operation effect. The utility model solves the problem of that the current mask products of support base and bracket can not rotate freely and precisely, and moreover, improves the usage and convenience of the mask products to a much perfect stage.

Description

Freely turn to bearing

Technical field

The utility model relates to a kind of bearing of fixed support plane framework, particularly can be used for the bearing that the vertical plane mask turns to.

Background technique

The bearing that is used for the support fixation plane framework in the prior art, more original mode are back side system one bearing diagonals at mask, utilize leg-of-mutton stability principle fixed bearing mask, so that the plane frame carrier on the supporting desktop, tripod.Present bearing nearly all is shaped on a pedestal and outwardly directed support, and the plane frame is fixed on the support.Such as the bearing that supports the computer liquid crystal display, photographic tripod bearing etc. all are that mask is fixedly supported on the support.In vertical plane, have indeflectible defective, and can not freedom regulate sense of rotation exactly and adjust pitching angle.Certainly, for the plane framework carrier that compares fixed placement, such support there is no big harm, but for the mask that may need to turn at any time, such fixed bearing will bring many inconvenience.

Summary of the invention

The purpose of this utility model is to have above-mentioned deficiency at the prior art bearing, and providing a kind of can turn in 360 ° of scopes of vertical plane, and simple in structure, the angle break-in freely turns to bearing efficiently.

The technological scheme that its technical problem that solves the utility model adopts is: a kind of bearing that freely turns to, support and mask with a supporting plane framework, it is characterized in that: described stent support face is provided with the arc opening that connects rotating shaft fixed block and calibration positioning disk, described rotating shaft fixed block is fixedlyed connected with the scale plate of described calibration positioning disk by mask drain pan interfix hole, is rotating perpendicular to the direction pitching of mask or is making scale plate around 360 ° of calibration rotations of drain pan center hole so that drive rotating shaft.

The utility model has following beneficial effect than prior art.

The utility model makes and drives rotating shaft perpendicular to the direction pitching rotation of mask or make the simple and direct structure of scale plate around 360 ° of calibration rotations of drain pan center hole, with the simplest and mode makes the product that is fixed on mask that the angle break-in arranged, to adjust the elevation angle free efficiently efficiently.For the mask series products that needs at any time to rotate provides the convenience of operating break-in, the flexibility of accurate adjusting rotation direction and the effect of getting twice the result with half the effort have been increased.The mask product that has solved prior art band bearing, support can not free technical problem of accurately regulating direction.Improve and expanded the function of mask class support product and the convenience of use, show more perfectly characteristic purposes.

In order to further specify rather than limit above-mentioned implementation of the present utility model, below in conjunction with drawings and Examples the utility model is further specified, but therefore the utility model is not limited among the described practical range.All these designs should be considered as disclosed content of present technique and protection domain of the present utility model.

Embodiment

In Fig. 1～Fig. 4, be provided with the arc opening of a connection rotating shaft fixed block 2 and calibration positioning disk at support 3 supporting surfaces of supporting plane framework.Support 3 is connected with rotating shaft fixed block 2 is rotated along both sides, is fixed in support 3 support 3 intermediate portions are maintained static, the rotating shaft 4 of two sideway swivels.Rotating shaft fixed block 2 is fixedlyed connected with the scale plate that constitutes the calibration positioning disk by mask drain pan 6 interfix hole A, makes the driving rotating shaft rotate perpendicular to the direction pitching of mask or make scale plate around 360 ° of calibration rotations of drain pan center hole.Rotating shaft fixed block 2 is fixed into by two screws 1 with rotating shaft 4 and makes 3 liang of sideway swivels of support, the fixed connection of intermediate portion, rotating shaft fixed block 2 both sides pivotable parts are fixedlyed connected with support 3 both sides, so that its support 3 rotates, torsion by rotating shaft 4 rotates, adjust the angle of mask, can stop at the arbitrary position after support 3 is rotated.Rotational fixture 2 is fixedlyed connected by four screws 8 of mask drain pan 6 interfix hole A and scale plate 7 usefulness, groove B on the scale plate 7 and the corresponding concavo-convex cooperation of the protruding C of mask drain pan 6,6 projectioies of mask drain pan are distributed in to be with on the flexible fin D, support 3 drives scale plate 7 and slides and mask drain pan 6 projectioies 360 ° of swinging mountings 3 in rotation.The groove B of present embodiment and protruding C press 90 ° of equation graduations of circumference, and four jiaos of branches such as angle distribute, so that mask traverse or place vertically.

Scale plate 7 connects firmly both sides, front and back at mask drain pan 6 by screw 8 and rotating shaft fixed block 2.Rotating shaft fixed block 2 passes through screw 1 and screw 8 priorities and rotating shaft 4 and support 3 formation fixed connections, just can drive rotating shaft 4 under support 3 acts on outside and rotate perpendicular to the direction pitching of mask or scale plate 7 is rotated in the vertical plane of mask drain pan 6.Rotating shaft fixed block 2 is subjected to the restriction in the gap after the restriction of drain pan 6 center hole A and scale plate 7 assemblings can only do rotation around center hole A.Groove B on the scale plate 7 is corresponding with the protruding C of mask drain pan 6, and concavo-convex cooperation is by 90 ° of circumference five equilibriums, makes mask 90 ° of rotations calibration and traverse or place vertically.Described calibration positioning disk is made of the mask drain pan 6 that scale plate 7 and the corresponding calibration of the fluted B of calibration has protruding C.Wherein, constitute the scale plate 7 of calibration positioning disk and the protruding C on the mask drain pan 6, calibration of groove B of concavo-convex corresponding matching and protruding C also can distribute and arbitrarily angled rotation positioning by 360 ° arbitrarily angled five equilibrium on it.Promptly by increase respectively with reduce scale plate 7 on groove B reach different calibration with the five equilibrium quantity of the protruding C of mask drain pan 6.Scale plate 7 can be adjusted distribution with the convex-concave and the flexible fin of mask drain pan 6, and scale plate 7 also can be by other bind mode and the driving mode purpose that reaches calibration.

Above-described only is preferred embodiment of the present utility model.Should be understood that; for the person of ordinary skill of the art; under the prerequisite that does not break away from the utility model principle; can also make some distortion and improvement; such as; mask drain pan described in the utility model can be the connecting plate assembly that connects the mask backboard, and support can be connected with base etc., and these changes and change should be considered as belonging to protection scope of the present invention.
