The hinge structure may be located at any position on the side where the door sill 20 and the door frame 10 are hinged, such as at an upper, lower or middle position on the hinged side. Meanwhile, the hinge structure may be provided with one or more. When the hinge structures are provided as one, the hinge side may also be provided with a rotation structure 40 to assist the rotation of the door sill 20. Therefore, the door sill 20 has a plurality of fulcrums when rotating, so that the door sill 20 can be prevented from shaking, and the stability of the door sill 20 when rotating is improved. Referring to fig. 1 and 2, in the present embodiment, the hinge structure is disposed at a lower portion of a side where the door sill 20 and the door frame 10 are hinged, and the rotating structure 40 is disposed at an upper portion of the side where the door sill 20 and the door frame 10 are hinged. The rotating structure 40 includes a fixed portion that can rotate relative to the fixed portion and has a certain amount of movement in the axial direction, the fixed portion being connected to the door frame 10, and a rotating portion that is connected to the door sill 20 and rotates in cooperation with the door sill 20 by rotation of the rotating portion relative to the fixed portion.

Since the conventional safety door fence is in a free state relative to the door frame 10 after the door fence 20 is opened, the door fence 20 needs to be manually closed, and when the door fence 20 and the door frame 10 are forgotten to be locked, children or pets are very easy to break the protection function of the safety door fence and enter a limited area, which is easy to cause danger. In order to solve the above problem, the hinge structure provided in this embodiment can realize an automatic return function, so that the door fence 20 can be automatically closed after being opened, thereby improving the safety of the safety door fence.

Specifically, as shown in fig. 3-4, the hinge structure includes a rotating member 1 and a base 2, the base 2 is connected to the door frame 10, the rotating member 1 is connected to the door sill 20, the base 2 is provided with a through hole 21, the rotating member 1 is rotatably connected to the through hole 21, the rotating member 1 is provided with a rotation recovery member 3, one end of the rotation recovery member 3 abuts against the bottom of the rotating member 1, and the other end abuts against the inner wall of the through hole 21; a backing plate 23 is arranged on the inner wall of the through hole 21, the rotating piece 1 penetrates through the backing plate 23, and an axial restoring piece 4 is connected between the bottom end of the rotating piece 1 and the backing plate 23; the upper edge 22 of the through hole 21 is provided with a first groove 211, and the top of the rotating member 1 is provided with a projection 11 capable of being matched with the first groove 211.

The hinge structure realizes the return of the rotating angle of the rotating part 1 after rotating by arranging the rotating return part 3 on the rotating part 1; an axial restoring piece 4 is connected between the bottom end of the rotating piece 1 and the backing plate 23, so that the position of the rotating piece 1 in the axial direction is restored; the upper edge 22 of the through hole 21 is provided with a first groove 211, the top of the rotating part 1 is provided with a convex block 11 matched with the first groove 211, when the rotating and restoring part 3 drives the rotating part 1 to rotate and restore to the position where the convex block 11 is opposite to the first groove 211, the axial restoring part 4 drives the rotating part 1 to axially move, so that the convex block 11 is clamped in the first groove 211, the rotating part 1 is clamped and fixed with the base 2, and the rotating part 1 restores to the initial position and limits the rotation of the rotating part 1. At this time, the door rail 20 and the door frame 10 are in a closed state, and the hinge structure can perform a function of automatically returning after rotating.

The rotation recovery member 3 includes at least two torsion springs 31, and two torsion springs 31 are all located on rotating the piece 1, and the one end of torsion spring 31 is connected in rotating the piece 1, and the other end butt is in the inner wall of through-hole 21, and two torsion springs 31 are configured to the rotation recovery opposite direction to rotating the piece 1. Taking the angle shown in fig. 4 as an example, when the rotating member 1 is driven counterclockwise as viewed from top to bottom, the upper torsion spring 31 is twisted, and when the driving force for the rotating member 1 is released manually, the restoring force of the upper torsion spring 31 drives the rotating member 1 to rotate clockwise, returning to the initial position; when the rotating member 1 is driven clockwise, the torsion spring 31 below is twisted, and when the driving force for the rotating member 1 is released manually, the restoring force of the torsion spring 31 below drives the rotating member 1 to rotate counterclockwise and return to the initial position. By providing two torsion springs 31, it is possible to achieve the restoration of the two opposite rotation directions of the rotation member 1.

As shown in fig. 4 and 5, in order to facilitate the connection between the torsion spring 31 and the rotating member 1, a locking groove 12 is axially formed on the outer circumferential surface of the rotating member 1, and one end of the torsion spring 31 is inserted into the locking groove 12. When the rotating member 1 is driven to rotate, the engaging groove 12 can drive the torsion spring 31 to rotate. The number of the locking grooves 12 is at least one, and in this embodiment, one locking groove 12 is provided corresponding to each of the two torsion springs 31.

As shown in fig. 3, the axial restoring element 4 is a spring, one end of which is connected to the bottom of the rotating element 1, and the other end of which abuts against the backing plate 23. Before the rotating member 1 is driven to rotate, the rotating member 1 needs to be lifted in the axial direction first, so that the convex block 11 of the rotating member 1 is separated from the first groove 211, and at this time, the spring is compressed due to the lifting of the bottom of the rotating member 1; when the rotating member 1 is returned, the rotating member 1 moves downward along the axial direction under the action of the gravity of the rotating member 1 and the elastic force of the spring, the protrusion 11 is engaged with the first groove 211, and the rotating member 1 returns to the initial position. The bottom of the rotating member 1 is connected with a pad 13, and one end of the spring abuts against the pad 13. The spacer 13 is used to prevent the spring from falling off, and can facilitate the mounting of the spring.

As shown in fig. 6, the upper edge 22 of the through-hole 21 is inclined downward to a side near the first recess 211. Through the upper edge 22 arranged obliquely, the lug 11 can move along the upper edge 22 when the rotating member 1 returns, so that the rotating member 1 can return quickly and smoothly.

The upper edge 22 of the through hole 21 is further provided with at least one second groove 212, and when the rotating member 1 rotates until the protrusion 11 is opposite to the second groove 212, the protrusion 11 can be clamped in the second groove 212. By providing the second groove 212, when the protrusion 11 is located in the second groove 212, the rotating member 1 can be maintained at the position, and when the driving force to the rotating member 1 is released, the rotating member 1 does not perform the restoring operation. Preferably, the angle between the second groove 212 and the first groove 211 in the circumferential direction of the through-hole 21 is 90 °. It can be ensured that the rotary member 1 remains in this position without returning when it is rotated to 90 deg., and returns when it is less than 90 deg.. When the door sill is applied to a safety door sill, the door sill 20 can be ensured not to be closed when being opened to 90 degrees, and can be kept in a normally open state; and the door sill 20 can automatically return when opened to less than 90 degrees.

The notches of the first groove 211 and the second groove 212 are both expanded, and the side walls of the first groove 211 and the second groove 212 are both in arc transition with the upper edge 22 of the through hole 21, so that the fluency of the rotating process of the rotating member 1 is improved.

The working principle of the safety door sill with the hinge structure is as follows:

when the door fence 20 needs to be opened, the door fence 20 is lifted a certain distance first, and the rotating member 1 is driven to lift a certain distance, so that the protrusion 11 is separated from the first groove 211, and at this time, the spring is compressed. Then the door rail 20 is pushed to rotate, the rotating member 1 rotates accordingly, and the protrusion 11 moves along the upper edge 22 of the through hole 21. When the opening position of the door sill 20 does not reach a certain angle (i.e. the protrusion 11 does not move to the second groove 212), if the door sill 20 is released, the rotating member 1 returns under the driving of the restoring force of the torsion spring 31, the restoring force of the spring and its own gravity until the protrusion 11 is locked in the first groove 211, and the door sill 20 is in the initial state; when the opening position of the door sill 20 reaches the first angle (i.e. the protrusion 11 moves to the second groove 212 and is clamped in the second groove 212), the door sill 20 keeps an opening state, and is suitable for certain times that the door sill 20 needs to be opened all the time; when the door rail 20 is required to be closed when the door rail 20 is kept in the open state, the door rail 20 is only required to be lifted for a certain distance and slightly moved towards the direction of closing the door rail 20, so that the protrusion 11 is separated from the second groove 212, and the rotating member 1 is driven by the restoring force of the torsion spring 31, the restoring force of the spring and the self gravity to return, so as to drive the door rail 20 to be closed.

It is obvious that the above embodiments of the present invention are only examples for clearly illustrating the present invention, and are not intended to limit the embodiments of the present invention. Other variations and modifications will be apparent to persons skilled in the art in light of the above description. And are neither required nor exhaustive of all embodiments.
