Among them, the door, as a house partition structure, is composed of a door frame and a door panel. In windy weather, the doors and windows of the house are generally closed or fixed in position to avoid damage caused by external forces.

[0003] After searching, the Chinese patent publication number CN207194674U discloses a door frame positioning device, in which the rotating shaft of the door frame positioning device is connected to one end of the device bracket, and a suction cup is installed at one end of the rotating shaft extending out of the device body, and a base is arranged at the other end of the device bracket, and a rubber block is arranged on the lower surface of the base, and the suction cup surface of the suction cup is arranged to be vertically arranged with the rubber block surface of the rubber block.

[0004] A door frame positioning device in the above patent has the following shortcomings: the above device offsets the force when the door is opened from the outside or blown open by the wind through the friction between the rubber block installed at the bottom of the base and the ground, but in real life, many door structures can be opened not only from the outside to the inside, but also from the inside to the outside. When opening from the inside to the outside, the friction of the rubber block is not sufficient to position the door. Utility Model Content

DETAILED DESCRIPTION

[0026] The technical solutions in the embodiments of the present invention will be described clearly and completely below in conjunction with the drawings in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, rather than all of the embodiments. Embodiment 1:

[0027] A door frame positioning device, such as Figure 1-Figure 5 As shown, it includes a locking mechanism on the outside of the door frame 2, the inner wall of the door frame 2 is rotatably connected to a center rod 12, the outer side wall of the center rod 12 is connected to a door panel 1 through a key, and the outer side wall of the center rod 12 is connected to a gear 3 through a key. The locking mechanism includes a gear 2 4, a movable plate 5, a guide block 6, and a mounting plate 7. The guide block 6 and the mounting plate 7 are both fixed to the outer side wall of the door frame 2 by bolts, the inner wall of the mounting plate 7 is rotatably connected to a rotating column 8, and a spiral groove 15 is provided on the outer side wall of the rotating column 8. The movable plate 5 is slidably connected to the outer side wall of the guide block 6, and a matching head 16 is welded to the outer side wall of the movable plate 5, and the matching head 16 cooperates with the spiral groove 15. The gear 2 4 is rotatably connected to the top outer wall of the door frame 2, the gear 2 4 is meshed with the gear 1 3, and a socket 13 is provided on the top of the gear 2 4. A locking rod 14 is welded to the bottom outer wall of the movable plate 5, and the locking rod 14 cooperates with the socket 13. A rotating component is slidably connected inside the rotating column 8.

[0028] First, rotate the rotating column 8 through the rotating component, and the movable plate 5 moves upward, canceling the cooperation between the locking rod 14 and the socket 13 at the bottom of the movable plate 5, and then rotate the door panel 1, which can drive the gear 1 3 outside the center rod 12 to engage and rotate the gear 2 4. After the gear 2 4 rotates, the rotating component rotates the rotating column 8 to reset, and with the cooperation of the spiral groove 15 and the matching head 16 outside the rotating column 8, the movable plate 5 moves downward, and the locking rod 14 is inserted into the socket 13 to fix the position of the gear 2 4, thereby achieving the effect of locking the door panel 1 after rotation. Regardless of whether the door panel 1 is rotated inward or outward, the rotation angle of the door panel 1 inside the door frame 2 can be positioned in this way.

[0029] An illumination lamp 17 is fixed to the inner wall of the gear 1 3 by bolts. When the gear 1 3 rotates, the illumination lamp 17 can project the angle after rotation on the ground, so that the user can determine the rotation angle of the door panel 1 conveniently.

[0030] The rotating assembly includes a rotating rod 9 and a coil spring 18. The rotating rod 9 is slidably connected to the inner wall of the rotating column 8. The coil spring 18 is clamped between the rotating column 8 and the mounting plate 7. A turning handle 11 is welded to the end of the rotating rod 9. A spring 19 is welded between the rotating rod 9 and the inner wall of the rotating column 8.

[0031] When in use, the handle 11 can be used to rotate the rotating rod 9, thereby driving the rotating column 8 to realize the cancellation of the positioning of the locking rod 14 at the bottom of the movable plate 5 on the socket 13. After the door panel 1 is rotated, the spring 19 pulls the rotating rod 9 to reset. At the same time, the coil spring 18 can drive the rotating column 8 to reset and rotate after the door panel 1 is rotated, thereby realizing the reset of the locking rod 14, and then the locking rod 14 is inserted into the socket 13 to position and fix the gear 2 4.

[0032] Working principle: by turning the handle 11, the turning rod 19 is rotated to drive the turning column 8 to realize the cancellation of the positioning of the locking rod 14 at the bottom of the movable plate 5 on the socket 13, and then the door panel 1 is rotated, and the door panel 1 can drive the gear 13 outside the center rod 12 to engage and rotate the gear 2 4. After the gear 2 4 rotates, the coil spring 18 drives the turning column 8 to reset, and under the cooperation of the spiral groove 15 and the matching head 16 outside the turning column 8, the movable plate 5 moves downward, and the locking rod 14 is inserted into the socket 13 to fix the position of the gear 2 4, thereby realizing the effect of locking the door panel 1 after rotation. No matter the door panel 1 is rotated inward or outward, the rotation angle of the door panel 1 inside the door frame 2 can be positioned in this way. Embodiment 2:

[0033] A door frame positioning device, for easy operation, such as Figure 1-Figure 5As shown, a friction column 10 is bonded to the outer side wall of the turning handle 11, a moving column 22 is slidably connected to the inner wall of the door frame 2, a spring 21 is welded between the moving column 22 and the inner wall of the door frame 2, and a chuck 20 is welded to the outer side wall of the moving column 22, and the inner diameter of the chuck 20 is the same as the diameter of the friction column 10.

[0034] Working principle: when the rotating rod 9 is rotated by pulling the rotating handle 11 to drive the rotating column 8 to rotate completely, when the spring 19 pulls the rotating rod 9 to reset, the friction column 10 outside the rotating handle 11 will squeeze the clamp 20 into its interior, and when the coil spring 18 drives the rotating column 8 to reset and rotate, the rotation speed of the rotating rod 9 and the rotating handle 11 will be slowed down by the friction between the clamp 20 and the friction column 10. When the moving plate 5 is reset to position the gear 2 4, the user is given a certain amount of time to determine the rotation angle of the door panel 1, and then it is automatically positioned.

[0035] The above description is only a preferred specific implementation manner of the present invention, but the protection scope of the present invention is not limited thereto. Any technician familiar with the technical field can make equivalent replacements or changes within the technical scope disclosed by the present invention according to the technical scheme and the utility model concept of the present invention, which should be covered by the protection scope of the present invention.
