Detailed Description

The technical solutions in the embodiments of the present invention will be clearly and completely described below with reference to the drawings in the embodiments of the present invention, and it is obvious that the described embodiments are only a part of the embodiments of the present invention, and not all of the embodiments. All other embodiments, which can be derived by a person skilled in the art from the embodiments given herein without making any creative effort, shall fall within the protection scope of the present invention.

Example 1

Referring to fig. 1-5, the present invention provides a technical solution: the utility model provides a realize 180 degrees locking of just reversing and take hinge of backstop structure, including casing 1 and last casing 2 down, casing 1 has axis of rotation piece 12 through the many first screw hole post 11 fixed mounting that are equipped with down, install between the outside of axis of rotation piece 12 and the last casing 2 and be used for carrying out the locking mechanism 3 of 180 degrees locking of just reversing to the hinge, locking mechanism 3's inside still installs and is used for carrying out the backstop mechanism 4 of backstop to the hinge, the torsion mechanism 5 that is used for providing torsion is installed at the axle head top of axis of rotation piece 12.

In this embodiment: three first screw hole posts 11 are arranged in the lower shell 1 in a triangular distribution mode, and the first screw hole posts 11 are fixedly connected with a base of the rotating shaft part 12 through screws.

Specifically, the base of the plurality of first threaded columns 11 matched with the threaded rods and the rotating shaft 12 is fixed, so that the rotating shaft 12 can be rapidly installed in the lower shell 1.

In this embodiment: go up the inside of casing 2 and be triangular distribution and install three second screw hole posts 21, locking mechanism 3 includes the cam 31 through screw rod and 21 fixed mounting of second screw hole post, the top of cam 31 is equipped with concave wheel board 32, the axle head outside of rotating shaft 12 is all located through the shaft hole cover that the middle part was opened to cam 31 and concave wheel board 32, the top fixed mounting of cam 31 has two archs 311 that the symmetry set up, the bottom of concave wheel board 32 is equipped with and protruding 311 locking complex recess 321.

Specifically, the cam 31 is installed in the upper housing 2 through the screw rod matching with the second threaded post 21, so that the upper housing 2 can drive the cam 31 to rotate when rotating, and the cam 31 can drive the concave wheel plate 32 to rotate and lock when rotating in cooperation with the stopping mechanism 4.

The shaft hole of the concave wheel plate 32 is a flat hole, and the size of the shaft end of the rotating shaft 12 is matched with the size of the shaft hole sleeving part of the concave wheel plate 32.

In this embodiment: the stopping mechanism 4 comprises a curved guide rail 41 arranged at the top of the cam 31, a sliding column 42 is connected in the curved guide rail 41 in a sliding manner, and the top of the sliding column 42 is connected with a moving guide groove 43 arranged at the side of the concave wheel plate 32 in a penetrating manner.

Specifically, the cam 31 can carry the sliding column 42 to perform guiding sliding in the curved guide rail 41 when rotating, and when the sliding column 42 moves to the end point of the rail, a stop is realized.

In this embodiment: the torsion mechanism 5 comprises a stacked spring 51 which is positioned on the top of the concave wheel plate 32 and sleeved outside the shaft end of the rotating shaft part 12, and a snap spring 52 is installed at the top end of the shaft end of the rotating shaft part 12.

Specifically, when the cam 31 rotates, the stacked spring 51 and the snap spring 52 can provide a certain torque force, so that the hinge has better mechanical feedback for the rotation.

The working principle is as follows: the lower shell 1 is fixed, when the upper shell 2 rotates clockwise, the cam 31 is driven to synchronously move clockwise, the sliding column 42 moves along the curve guide rail 41, at the same time, the concave wheel plate 32 and the rotating shaft piece 12 are fixed with the lower shell 1, when the cam 31 drives the sliding column 42 to move to 180 degrees, the sliding column 42 moves to one end of the curve guide rail 41 at the same time, the stopping is realized, and meanwhile, the bulge 311 of the cam 31 is overlapped with the groove 321 of the concave wheel plate 32, and the locking is realized;

when the hinge moves from 180 degrees to 0 degree, the upper shell 2 drives the protrusion 311 to move synchronously, at the moment, the protrusion 311 slides out of the groove 321, meanwhile, the sliding column 42 is driven to move synchronously, when the cam 31 drives the sliding column 42 to move to 0 degree, the protrusion 311 of the cam is superposed with the groove 321 of the concave wheel plate 32 again, and locking is achieved similarly;

it should be added that: the stopping angle between the sliding column 42 and the curved guide rail 41 can be any angle smaller than 360 degrees, only the end point of the guide rail needs to be set, and certainly, the included angle between the protrusion 311 of the cam 31 and the groove 321 of the concave wheel plate 32 can be selected according to actual needs, so that the locking of the hinge at different angles is realized.

Although the present invention has been described in detail with reference to the foregoing embodiments, it will be apparent to those skilled in the art that various changes, modifications, equivalents, and improvements may be made without departing from the spirit and scope of the utility model.
