Abstract
The invention relates to a rotation hinge structure, which comprises an upper hinge and a lower hinge; the upper hinge is fixedly connected with a hinging shaft; the hinging shaft movably sleeves in a hinging sleeve of the lower hinge; an arc-shaped groove of which the cross section is at an angle of 60 degrees is formed in the inner wall face of one of ends of the hinging sleeve; an angle limiting stopper is inserted into the arc-shaped groove; the angle limiting stopper has two side faces which are attached to the arc-shaped groove and form an included angle of 60 degrees; the two side faces of the angle limiting stopper are located on an inner diameter line of the hinging sleeve; the end part of the hinging sleeve is provided with a screwing-down cap; the screwing-down cap is in threaded connection with the hinging sleeve; the inner end face of the screwing-down cap axially abuts against the angle limiting stopper; and one of side faces, attached to the angle limiting stopper, of the end part of the hinging shaft is fixedly connected with a limiting plate. According to the rotation hinge structure of such structure, by matching the limiting plate with the angle limiting stopper, constant-120-degree rotation of the hinging shaft is realized.
Description
Technical field
The present invention relates to a kind of rotary hinge structure。
Background technology
Hinge arrangement of the prior art generally can large rotation angle, rotational angle range is comparatively free, but be typically implemented in some use occasion and determine angular turn, the special scope as rotated 120 degree of demand that this special applications is more, it is therefore desirable to a kind of new rotary hinge structure is provided。
Summary of the invention
It is an object of the invention to overcome above-mentioned problem of the prior art, it is provided that a kind of rotary hinge structure, it can realize 120 degree and determine angle rotation。
It is an object of the invention to be achieved through the following technical solutions:
Rotary hinge structure, including upper hinge and lower jaw, connecting hinge spindle fixed by described upper hinge, described jointed shaft is movably set in the hinged set of described lower jaw, it is the arcuate groove of 60 degree that the internal face of wherein one end of described hinged set is provided with cross section, angle limit block it is fitted with in described arcuate groove, described angle limit block has the two sides in 60 degree of angles fitted with described arcuate groove, the two sides of described angle limit block are positioned on the radial line of described hinged set, the end of described hinged set is provided with screwed cap, described screwed cap is connected with described hinged external threading, the inner face of described screwed cap axially supports described angle limit block, one of them side of the described angle limit block of end laminating of described jointed shaft is fixedly connected with limiting plate。
Further, the length of described limiting plate is more than the radius length of described jointed shaft。
Further, described hinged putting is provided with the notch rotated for described upper hinge。
Further, the length of described angle limit block is more than or equal to the degree of depth of described arcuate groove。
Rotary hinge structure of the present invention, including upper hinge and lower jaw, connecting hinge spindle fixed by upper hinge, jointed shaft is movably set in the hinged set of lower jaw, it is the arcuate groove of 60 degree that the internal face of wherein one end of hinged set is provided with cross section, angle limit block it is fitted with in arcuate groove, angle limit block has the two sides in 60 degree of angles fitted with arcuate groove, the two sides of angle limit block are positioned on the radial line of hinged set, the end of hinged set is provided with screwed cap, screwed cap is connected with hinged external threading, the inner face of screwed cap axially supports angle limit block, one of them side of the end laminating angle limit block of jointed shaft is fixedly connected with limiting plate。The rotary hinge structure of this structure, by coordinating of limiting plate and angle limit block, it is achieved thereby that jointed shaft 120 degree determines angular turn。

Detailed description of the invention
Below according to drawings and Examples, the present invention is described in further detail。
Such as Fig. 1, shown in Fig. 2 and Fig. 3, a kind of rotary hinge structure described in the embodiment of the present invention, including hinge and lower jaw 2 on 1, connecting hinge spindle 3 fixed by upper hinge 1, jointed shaft 3 is movably set in the hinged set 4 of lower jaw 2, it is the arcuate groove of 60 degree that the internal face of wherein one end of hinged set 4 is provided with cross section, angle limit block 5 it is fitted with in arcuate groove, the two sides in 60 degree of angles that angle limit block 5 arcuate groove fits, the two sides of angle limit block 5 are positioned on the radial line of hinged set 4, the end of hinged set 4 is provided with screwed cap 6, screwed cap 6 is threadeded with hinged set 4, the inner face of screwed cap 6 axially supports angle limit block 5, one of them side of the end laminating angle limit block 5 of jointed shaft 3 is fixedly connected with limiting plate 7。The length of limiting plate 7 is more than the radius length of jointed shaft 3。
Hinged set 4 is provided with the notch (not shown) rotated for upper hinge。The length of angle limit block 5 is more than or equal to the degree of depth of arcuate groove。
The rotary hinge structure of this structure, by coordinating of limiting plate and angle limit block, it is achieved thereby that jointed shaft 120 degree determines angular turn。
The foregoing is only explanation embodiments of the present invention; be not limited to the present invention, for a person skilled in the art, all within the spirit and principles in the present invention; any amendment of being made, equivalent replacement, improvement etc., should be included within protection scope of the present invention。
