Example 1

As shown in fig. 1, the fixed hinge 1 is movably connected to the movable hinge 2, that is, the fixed hinge 1 and the movable hinge 2 can rotate relatively, a hinge core 4 is inserted into the connection portion, and the hinge core 4 can only slide along the linear direction of the hinge core 4 relative to the fixed hinge 1, but cannot rotate relative to the fixed hinge 1. One end of the hinge mandrel 4 is provided with a spline 41, the splines 41 on the upper hinge mandrel 4 and the lower hinge mandrel 4 on the fixed hinge 1 are all towards the transverse symmetrical line of the fixed hinge 1, the spline housing 3 is installed at the center of the inner side of the movable hinge 2, when the two hinge mandrels 4 move towards the middle, the ends provided with the splines 41 can be inserted into the spline housing 3 in a inserting mode, and the movable hinge 2 after being inserted is locked relative to the fixed hinge 1. Two driving devices 6 are arranged above and below the fixed hinge 1, each driving device 6 correspondingly controls the movement of one hinge mandrel 4, when the locking state of the hinge needs to be cancelled, the output end of each driving device 6 drives the hinge mandrels 4 to move up and down, and when the spline 41 is separated from the spline housing 3, the fixed hinge 1 and the movable hinge 2 can rotate freely.

In some examples, the fixed hinge 1 and the movable hinge 2 are provided with mounting holes, into which bolts 5 or screws can be inserted for mounting the fixed hinge 1 and the movable hinge 2.

In some examples, the driving device 6 may be a stepping motor, an electric screw rod or an electrically controlled slide rail, i.e. the output end of the driving device 6 can move linearly.

As shown in fig. 2, the output end of the drive device 6 in fig. 2 is in an initial state, and the hinge spindle 4 connected to the output end is fixed in position relative to the fixed hinge 1. After the output end of the driving device 6 drives the hinge mandrel 4 to move towards the middle of the fixed foldout 1, as shown in fig. 3, the hinge in fig. 3 is in a locking state, the spline 41 at the end part of the hinge mandrel 4 is inserted into the spline housing 3 on the movable foldout 2, the fixed foldout 1 is locked relative to the movable foldout 2, and the hinge cannot rotate.

As shown in fig. 5 and 6, the hinge core shaft 4 is provided with a circulating track 8, the circulating track 8 includes two crossed inclined tracks and two vertical tracks vertically arranged along the linear direction of the hinge core shaft 4, and the vertical tracks communicate with the end portions of the two inclined tracks. The movable folding leaf 2 is provided with a sliding part which is connected with the circulating track 8 in a sliding way, when the movable folding leaf 2 is transversely rotated, the sliding block 7 fixedly slides along the circulation, and the hinge mandrel 4 also moves along the linear direction of the hinge mandrel 4.

In some examples, the movable hinge 2 and the hinge core 4 are connected by a screw thread, and the hinge core 4 can be driven to move along the linear direction of the hinge core 4 by rotating the movable hinge 2.

In some examples, locking grooves 9 are provided at four ends in the circulation rail 8, and edges of the locking grooves 9 are provided with arc-shaped chamfers.

In some examples, the sliding block 7 is an electrically controlled telescopic sliding block 7, the sliding block 7 is stretched to be in sliding connection with the circulating track 8 when the electrically controlled telescopic sliding block 7 is opened, and the sliding block 7 is contracted to be separated from the circulating track 8 when the electrically controlled telescopic sliding block 7 is closed.

The working principle is that as shown in fig. 7, when the hinge mandrel 4 at the lower side of the hinge in fig. 1 is at the initial position, the slider 7 is located at the position a on the circulating track 8, the movable hinge 2 rotates counterclockwise, the slider 7 slides to the position b along the inclined track in the circulating track 8, during the process again, the hinge mandrel 4 gradually moves upwards, the spline 41 at the upper end of the hinge mandrel 4 is inserted into the spline housing 3, and the movable hinge 2 is locked relative to the fixed hinge 1 under the connection of the hinge mandrel 4. And (3) opening a driving device 6 above and below the fixed hinge 1, driving the hinge mandrel 4 to move downwards by the output end of the driving device 6, sliding the slide block 7 to the position c along the circulating track 8 in the bc direction at the moment, and releasing the locking state of the hinge. After the instantaneous needle rotates the movable hinge 2, the sliding block 7 moves along a cd track, the hinge mandrel 4 gradually moves upwards, when the sliding block 7 slides to a position d, the hinge is locked again, the driving device 6 is opened again, the output shaft of the driving device 6 drives the hinge mandrel 4 to move downwards, the sliding block 7 slides to a position a from the position d, and the hinge is unlocked again.

Further, the electric control telescopic slide block 7 is closed, and the electric control telescopic slide block 7 is not connected with the circulating track 8 in a sliding mode any more, so that the rotary movable hinge 2 cannot drive the hinge core shaft 4 to move along the linear direction of the hinge core shaft 4.

Example 2

The present embodiment is different from embodiment 1 in that a hinge core 4 having a spline 41 is attached to either one of the upper and lower sides of a fixed hinge 1 in the present embodiment.

Example 3

As shown in fig. 8, the door 11 is installed on the door frame 10 through the anti-theft safety hinge, an intelligent lock 12 is installed on the door 11, the intelligent lock 12 is connected with the driving end in a wired or wireless manner, the intelligent lock 12 controls the opening and closing of the driving device 6 as the control end of the driving device 6, the driving device 6 can be opened only under the specific condition of triggering the intelligent lock 12, for example, the intelligent lock 12 receives a signal and then opens and closes the driving device 6, or the handle on the intelligent lock 12 rotates and then opens and closes the driving device 6, or the intelligent lock 12 senses corresponding information and then opens and closes the driving device 6, wherein the corresponding information includes infrared sensing information, distance sensing information, temperature sensing information, vibration sensing information and the like.

Furthermore, the intelligent lock 12 is connected with the electric control telescopic sliding block 7 in a wired or wireless mode, so that the connection between the sliding block 7 and the circulating track 8 is opened and closed through the intelligent lock 12, and the function of locking the hinge with the circulating track 8 is further opened and closed.
