Detailed Description

The present invention will be further described with reference to the accompanying drawings. The utility model provides a take hinge of two-way locking, its includes fixed hinge 1, and activity hinge 2, and the fixed hinge 1 of 2 cladding of activity hinges is in it, and a articulated shaft 3 passes activity hinge 2 in proper order and is articulated with fixed hinge 1, and activity hinge 2 opens and shuts swing, its characterized in that along this articulated shaft 3 and fixed hinge 1: two side edges of the movable hinge 2 are bent outwards and extend to form a limiting plate 21, a plurality of limiting grooves 22 are formed in an opening in the front end of the penetrating limiting plate 21, correspondingly, two side edges of the fixed hinge 1 are bent outwards and extend to form a connecting plate 11, the connecting plate 11 is in butt joint with the limiting plate 21, the penetrating connecting plate 11 is provided with a sliding groove 12, a positioning rod 4 is embedded across the sliding groove 12, and the positioning rod 4 is clamped in the limiting groove 22 to lock the movable hinge 2; the locating lever 4 on install the elasticity structure that resets, the elasticity structure of resetting stimulates locating lever 4 all the time and moves toward spacing groove 22 direction, arranges locating lever 4 card in spacing groove 22 all the time.

The outer end surface of the limiting plate 21 is arc-shaped, and adjacent limiting grooves 22 are in transition connection through guide arc surfaces.

The number of the limiting grooves 22 is two, and an included angle between the two limiting grooves 22 is 90 degrees.

The elastic reset structure comprises a tension spring 5, one end of the tension spring 5 is hooked on the cylindrical surface of the positioning rod 4, the other end of the tension spring is hooked on a spring buckle 13 on the inner side wall of the connecting plate 11, the tension spring 5 generates tension force, and the positioning rod 4 is pulled to move towards the end 2 of the movable hinge all the time.

The two ends of the positioning rod 4 are provided with protruding sliding grooves 12, the ends are connected with control wrenches 6, the protruding control wrenches 6 are provided with handles 61, and handle sleeves 62 are sleeved outside the handles 61.

A clearance groove 63 is reserved between the control wrench 6 and the fixed hinge 1, and the limiting plate 21 of the movable hinge 2 is clamped in the clearance groove 63.

The movable hinge 2 and the fixed hinge 1 are arranged in a similar shape.

The working principle is as follows: in the fixing part and the moving part which need to be hinged with each other, such as a door body and a door frame, a movable hinge and a fixed hinge are respectively arranged between the door body and the door frame. Wherein, the two sides of the movable hinge are bent outwards and extended to form a limiting plate, a plurality of limiting grooves are arranged at the opening of the front end part penetrating through the limiting plate, correspondingly, the two sides of the fixed hinge are bent outwards and extended to form a connecting plate, and the connecting plate is in butt joint connection with the limiting plate. The end face of the connecting plate is provided with a sliding groove in a penetrating mode, the positioning rod is embedded in the sliding groove in a crossing mode, the positioning rod is clamped in different limiting grooves according to different using states, and therefore the position of the movable hinge is locked, and the state of the door body is locked.

Wherein, install the elasticity reset structure on the locating lever, the elasticity reset structure has included the extension spring, utilizes the one end hookup of extension spring on the cylinder of locating lever, and the other end then hookup is buckled in the snak link of connecting plate inside wall, and the extension spring has produced the pulling force, is pulling the locating lever all the time and is moving toward activity hinge end direction. After a user pulls the door body to a certain angle, the limiting grooves slide to the limiting grooves with the nearest distance and are clamped in the limiting grooves under the sliding action of the guide arc surfaces, and therefore the positioning rod is locked and clamped in the limiting grooves all the time.

Further, the limiting grooves are provided with two, the included angle between the two limiting grooves can be set to be 90 degrees, namely, the door body can be locked in two states of opening the door or closing the door, the locking is effectively carried out on the use state of the door body, the situation that the door body swings randomly is avoided, the personal safety of a user is effectively guaranteed, and the door body is protected from being damaged. Compare with the traditional door body that only locks the state of closing the door, this hinge has not only add the locking of running from opposite directions the state of closing the door, improves its security, and its locking operation does not need the user to go on alone simultaneously, opens at the door body and can accomplish the locking automatically to certain angle, design benefit, and convenient operation is simple, has avoided loaded down with trivial details operation, has brought very big convenience for the user.

When a user needs to change the current state of the door body, the handle is formed at the end head of the control wrench in a protruding mode by the aid of the control wrench connected with the end head of the positioning rod, the handle is pulled outwards to bring pulling force to the positioning rod to enable the positioning rod to be separated from the limiting groove, and the user can easily change the state of the door body at the moment so that the door body can be more suitable for actual use, and therefore the door body can be widely popularized.

The foregoing shows and describes the basic principles and principal features of the invention, together with the advantages thereof. It will be understood by those skilled in the art that the present invention is not limited to the above embodiments, and that the foregoing embodiments and descriptions are provided only to illustrate the principles of the present invention without departing from the spirit and scope of the present invention.
