Technical Field

The utility model relates to a rotate the hinge, specifically be a rotation hinge of timber.

Background

Hinges are mechanical devices used to connect two solid bodies and allow relative rotation between them, and may be made of movable components or foldable materials, commonly known as hinges, which can be used for cabinet doors, windows, doors, etc. Domestic hinge is mostly general hinge, cooperates the door-inhale usually to come to carry out spacing and fixed action to the door, nevertheless inconvenient installation door-inhale in some places, then can cause the door because of the collision cause to the door, to the wall or even to personnel's injury.

SUMMERY OF THE UTILITY MODEL

An object of the utility model is to provide a rotation hinge of timber to solve the problem that proposes among the above-mentioned background art.

In order to achieve the above object, the utility model provides a following technical scheme:

a rotary hinge for wooden door is composed of six main parts including upper hinge, lower hinge, spring, rotary axle, flat key and limiting block, four axial key slots on the surface of axle, four axial key slots on the middle part of rotary axle, and limiting block connected to the surface of rotary axle, a spring is arranged between the limiting block and the upper hinge, the spring keeps a pre-tightening state, the limiting block is composed of a cylinder and a right-angled trapezoid cube formed by axially cutting the cylinder, meanwhile, the limiting block is internally provided with a groove matched with the flat key, so that the limiting block can move up and down along the rotating shaft, the root of the lower hinge leaf is provided with a rotating hole matched with the rotating shaft and a limiting hole matched with the limiting block, and the other end of the rotating shaft extends into the rotating hole of the lower hinge.

As a further aspect of the present invention: the degree of an angle formed by the inclined plane of the right trapezoid cube in the limiting block and two planes of the contact surface of the right trapezoid cube and the cylinder is 110-140 degrees.

As a further aspect of the present invention: the axial key groove formed in the limiting block takes any key groove as a reference, and the angle between the axial central line of the key groove and the right-angle side of the right-angle trapezoid cube is the angle for controlling the opening of the wooden door.

As a further aspect of the present invention: lower hinge connection is on the door frame, goes up hinge connection on the timber, under the effect of gravity, goes up hinge and lower hinge rotation connection.

Compared with the prior art, the beneficial effects of the utility model are that: through the cooperation of stopper and lower hinge, can open the timber and fix the angle of settlement, under the effect of not applying certain external force, the timber can not rotate because of natural reasons such as blowing promptly to reduce the door because of the collision causes to the door, to the wall and even to personnel's injury.

As shown in the figure: 1. the hinge comprises an upper hinge, 2 springs, 3 rotating shafts, 4 flat keys, 5 limiting blocks, 6 lower hinges, 11 upper hinge leaves, 31 key grooves, 51 cylinders, 52 right-angle trapezoidal cubes, 61 lower hinge leaves, 611 limiting holes and 612 rotating holes.

Detailed Description

The technical solutions in the embodiments of the present invention will be described clearly and completely with reference to the accompanying drawings in the embodiments of the present invention, and it is obvious that the described embodiments are only some embodiments of the present invention, not all embodiments. Based on the embodiments in the present invention, all other embodiments obtained by a person skilled in the art without creative work belong to the protection scope of the present invention.

Referring to fig. 1 to 4, in the embodiment of the present invention, a wooden door rotation hinge includes six main parts, which are an upper hinge 1, a lower hinge 6, a spring 2, a rotation shaft 3, a flat key 4 and a stopper 5, a leaf root 11 of the upper hinge 1 is fixedly connected to one end of the rotation shaft 3, four axial key slots 31 are formed in the middle of the rotation shaft 3 around the axis on the surface of the shaft, the flat key 4 is installed in the key slots 31, the stopper 5 is slidably connected to the surface of the rotation shaft 3, the spring 2 is arranged between the stopper 5 and the upper hinge 1, the spring 2 maintains a pre-tightening state, the stopper 5 is composed of a cylinder 51 and a right trapezoid cube 52 formed by cutting the cylinder axially, and a groove matched with the flat key 4 is formed inside the stopper 5 to allow the stopper 5 to move up and down along the rotation shaft 3, a rotating hole 612 matched with the rotating shaft and a limiting hole 611 matched with the limiting block 5 are formed in the root part 61 of the lower hinge 6, and the other end of the rotating shaft 3 extends into the rotating hole 612 of the lower hinge 6.

After accomplishing the hinge equipment, install on the timber, open the timber, at this moment, rotation axis 3 takes place to rotate, stopper 5 clockwise rotation under flat key 4 drives, until stopper 3 falls into spacing hole 611, because the effect on the 52 axial right-angle sides of right trapezoid cube, the timber is opened to the at utmost, because the effect on the 52 inclined planes of right trapezoid cube, the timber is under the effect that does not have certain external force, the timber also can't be closed, close the timber this moment, stopper 3 anticlockwise rotation under flat key 4 drives, the stopper slowly promotes, until whole spacing hole 611 that leaves, the timber is closed.

In the description of the present invention, it is to be noted that, unless otherwise explicitly specified or limited, the terms "mounted," "connected," and "connected" are to be construed broadly, and may be, for example, fixedly connected, detachably connected, or integrally connected; can be mechanically or electrically connected; they may be connected directly or indirectly through intervening media, or they may be interconnected between two elements.
