Abstract
The utility model relates to an end rotatory positioner, specifically speaking relates to a rotational positioning joint. Including rotation joint and fixed joint, rotation joint's right -hand member semicircular in shape is equipped with curved breach at its semicircular edge, be equipped with the rotation joint pilot hole on rotation joint's right -hand member, fixed joint's bottom semicircular in shape is equipped with fore -and -aft rectangular hole on fixed joint's upper portion, rectangular downthehole running through there is the locating pin, fixed joint's lower part is equipped with the fixed joint pilot hole, the fixed joint pilot hole is relative with the rotation joint pilot hole to it has the pivot to run through. The utility model discloses a rotation joint is rotatory to certain angle, fall rotation joint's breach through the gravity of the locating pin on the fixed joint is automatic in, block the breach, satisfy the automatic positioning effect, need only need stir the locating pin gently and remove along the rectangular hole on the fixed joint rotatory the time, keep away from the axle center, leave the breach, can rotate.
Description
Technical field
This utility model relates to a kind of positioner preventing and rotating, and specifically, relates to a kind of rotation positioning joint.
Background technology
In prior art, it is fixing that the axle of the rotary joint of the fold furniture such as chaise longue rotates location, is generally adopted screw location, latch location or folding device location, to prevent articulation. This traditional axle rotates device for positioning and securing inconvenient operation, fold furniture can not be allowed to rotate freely, also unsightly.
Utility model content
The purpose of this utility model is in that, it is provided that a kind of rotation positioning joint, to solve above-mentioned technical problem.
For solving the problems referred to above, this utility model be the technical scheme is that
A kind of rotation positioning joint, it is characterised in that: include cradle head and fixing joint; The right-hand member semicircular in shape of described cradle head, is provided with the breach of arc at its semicircular edge; The right-hand member of cradle head is provided with cradle head pilot hole; The bottom semicircular in shape of described fixing joint, is provided with longitudinal strip hole on the top of fixing joint, and running through in described strip hole has alignment pin; The bottom of described fixing joint is provided with fixing joint pilot hole; Described fixing joint pilot hole is relative with cradle head pilot hole, and runs through and have rotating shaft.
Saying further, the left side of described cradle head is the straight flange of longitudinal hypotenuse or longitudinal direction.
Further saying, the breach on the semicircular edge of described cradle head right-hand member is at least provided with one.
Beneficial effect: compared with prior art, cradle head of the present utility model rotates to certain angle, automatically fall in the breach of cradle head by the gravity of alignment pin on fixing joint, block breach, meet and be automatically positioned effect, it is necessary to when rotation, have only to stir alignment pin strip hole along fixing joint gently move, away from axle center, leave breach, namely rotatable; Additionally, cradle head arranges some breach, it is possible to meet the rotation location of different angles, change orientation angle by adjusting alignment pin from the cooperation of different breach.

Detailed description of the invention
Below in conjunction with the drawings and specific embodiments, the utility model is described in further detail.
With reference to Fig. 1-4, rotation positioning joint described in the utility model, including cradle head 1 and fixing joint 2.
The left side of described cradle head 1 is longitudinal hypotenuse. The right-hand member semicircular in shape of described cradle head 1, is provided with the breach 11 of an arc at its semicircular edge. The right-hand member of cradle head 1 is provided with cradle head pilot hole 12; The bottom semicircular in shape of described fixing joint 2, is provided with longitudinal strip hole 21 on the top of fixing joint 2, and running through in described strip hole 21 has alignment pin 4; The bottom of described fixing joint 2 is provided with fixing joint pilot hole 22; Described cradle head pilot hole 12 is relative with fixing joint pilot hole 22, and runs through and have rotating shaft 3.
As other embodiments of the present utility model, as it is shown in figure 5, the left side of described cradle head 1 is longitudinal straight flange. Breach 11 on the semicircular edge of described cradle head 1 right-hand member is provided with two.
Additionally, according to actual needs, the breach 11 on the semicircular edge of cradle head 1 right-hand member can also arrange two or more.
Operation principle of the present utility model: cradle head 1 rotates to certain angle, is fallen automatically by the gravity of alignment pin 4 on fixing joint 2 in the breach 11 of cradle head 1, and alignment pin 4 blocks breach 11, meets and is automatically positioned effect; When needing to rotate, it is only necessary to stir the alignment pin 4 strip hole 21 along fixing joint 2 gently and move, away from axle center, leave breach 11, namely rotatable; Additionally, cradle head 1 arranges some breach 11, it is possible to meet the rotation location of different angles, change orientation angle by adjusting alignment pin 4 from the cooperation of different breach 11.
