Description

Technical Field

[0001] The utility model relates to a door and window locking and positioning device, belonging to the technical field of door and window locking equipment. Background Art

[0002] Windows and doors are collectively referred to as doors and windows, which are an important part of the building shape. According to their different positions, they are divided into enclosure components or partition components, and have different design requirements, respectively having functions such as heat preservation, heat insulation, sound insulation, waterproofing, and fire prevention. New requirements are for energy conservation; when closing the doors and windows, it is necessary to lock them and limit their positions to prevent other external forces from opening the doors and windows, which can ensure the safety of the people inside the building.

[0003] However, when the existing door and window locking devices are applied to windows, they can often only be locked when the windows are closed, and when the windows are opened partially, they cannot be limited. At this time, the windows are easily affected by external forces to be completely opened or slammed shut (such as strong winds), which affects the use of the people inside the house. Now there is an urgent need for a door and window locking and positioning device to solve the above problems. Content of the Utility Model

[0004] Aiming at the deficiencies of the existing technology, the purpose of the utility model is to provide a door and window locking and positioning device to solve the problems proposed in the above background art. The utility model designs a swinging threaded insertion structure, which can lock and position the window when it swings open.

[0005] To achieve the above purpose, the utility model is realized by the following technical solutions: A door and window locking and positioning device includes a door and window outer frame, a bending plate, a semi-circular fixing piece, and a threaded positioning rod. The inner side of the door and window outer frame is installed with a door and window main body through a hinge. A plurality of positioning slot holes are opened at the lower end of the door and window main body from front to back. The bending plate is fixed to the lower left end of the door and window outer frame by two screws. A semi-circular fixing piece is integrally fixed to the rear end of the bending plate. A bearing is installed through the middle of the upper end of the semi-circular fixing piece. A rotating shaft is installed through the inner ring of the bearing. An extension plate is horizontally fixed to the front side of the upper end of the rotating shaft. A hand-tightening bolt is inserted into the extension plate by means of a threaded principle. A swinging rod is horizontally fixed to the lower end of the rotating shaft. An inner screw cylinder is longitudinally fixed to the other end of the swinging rod. The upper end of the inner screw cylinder is screwed with a threaded positioning rod by means of a threaded principle.

[0006] Furthermore, the lower end of the hand-tightening bolt abuts tightly against the semi-circular fixing piece.

[0007] Furthermore, an arc-shaped card slot is opened at the front end of the left side of the bending plate.

[0008] Furthermore, the inner screw cylinder is longitudinally clamped in the arc-shaped card slot.

[0009] Further, the upper end specifications of the threaded positioning rod match the specifications of the multiple positioning slots.

[0010] Further, an anti-slip block is fixed in the middle of the outer part of the threaded positioning rod.

[0011] Advantages of the present utility model: A door and window locking and positioning device of the present utility model. Due to the addition of a bending plate, a semi-circular fixing piece, a bearing, a rotating shaft, an extension plate, a hand-tightening bolt, a swinging rod, an internal screw cylinder, and a threaded positioning rod in the present utility model, through our design improvement and actual use, it shows that the device has a reasonable structure and good practicability. A swinging threaded insertion structure is designed, which can lock and position the window when it swings open, so that the window will not swing automatically when subjected to external forces.

DETAILED DESCRIPTION OF THE EMBODIMENTS

[0017] To make the technical means, creative features, achieved purposes, and functions of the present utility model easy to understand, the present utility model will be further described below in conjunction with specific embodiments.

[0018] Please refer to Figures 1 - 3, the present utility model provides a technical solution: a door and window locking and positioning device, including a door and window outer frame 1, a bending plate 4, a semi-circular fixing piece 6, and a threaded positioning rod 13. The inner side of the door and window outer frame 1 is installed with a door and window main body 2 through hinges. A plurality of positioning slot holes 3 are opened at the lower end of the door and window main body 2 from front to back. The bending plate 4 is fixed to the lower left end of the door and window outer frame 1 by two screws 5. A semi-circular fixing piece 6 is integrally fixed to the rear end of the bending plate 4. A bearing 7 is installed through the middle of the upper end of the semi-circular fixing piece 6. A rotating shaft 8 is installed through the inner ring of the bearing 7. An extension plate 9 is horizontally fixed to the front side of the upper end of the rotating shaft 8. A hand-tightening bolt 10 is inserted into the upper end of the extension plate 9 by means of a threaded principle. A swing rod 11 is horizontally fixed to the lower end of the rotating shaft 8. The other end of the swing rod 11 is longitudinally fixed with an inner screw cylinder 12. The upper end inside the inner screw cylinder 12 is screwed with a threaded positioning rod 13 by means of a threaded principle. This design solves the problem that when the original window is opened partially, it cannot be limited, and at this time, the window is easily affected by external forces to be completely opened or slammed shut, affecting the use of the people inside the house.

[0019] As the first embodiment of the present utility model: the lower end of the hand-tightening bolt 10 abuts against the semi-circular fixing piece 6. By adding that the lower end of the hand-tightening bolt 10 abuts against the semi-circular fixing piece 6, the rotating shaft 8 can be limited, so that the rotating shaft 8 will not rotate by itself. An arc-shaped card slot 14 is opened at the front end of the left side of the bending plate 4. The inner screw cylinder 12 is longitudinally clamped in the arc-shaped card slot 14. By adding the arc-shaped card slot 14, it is convenient for the bending plate 4 to be placed. The upper end specification of the threaded positioning rod 13 matches the specification of a plurality of positioning slot holes 3. By adding that the upper end specification of the threaded positioning rod 13 matches the specification of a plurality of positioning slot holes 3, when the upper end of the threaded positioning rod 13 is inserted into one of the positioning slot holes 3, the door and window main body 2 can be locked. An anti-slip block is fixed in the middle of the outside of the threaded positioning rod 13. By adding the anti-slip block, it is convenient for the user to rotate the threaded positioning rod 13.

[0020] As the second embodiment of the present utility model: during actual use, swing the door and window main body 2 to the left front, and then dial the swing rod 11 to the left front. The swing rod 11, the inner screw cylinder 12, and the threaded positioning rod 13 will swing around the rotating shaft 8 (during this process, the rotating shaft 8 and the inner ring of the bearing 7 rotate in place, and the outer ring of the bearing 7 remains unchanged, and the extension plate 9 and the hand-tightening bolt 10 will also be driven to change positions), until the threaded positioning rod 13 moves to directly below one of the positioning slot holes 3, and then turn the hand-tightening bolt 10 so that the lower end of the hand-tightening bolt 10 abuts against the semi-circular fixing piece 6, thereby limiting the rotating shaft 8, and thus preventing the swing rod 11, the inner screw cylinder 12, and the threaded positioning rod 13 from being driven to change positions. Then turn the threaded positioning rod 13 so that the threaded positioning rod 13 rotates and moves upward from the inner screw cylinder 12 until the upper end of the threaded positioning rod 13 is caught in one of the positioning slot holes 3, and the door and window main body 2 can be locked and positioned.
