They have different design requirements and must have functions such as thermal insulation, heat insulation, sound insulation, waterproofing, and fire prevention. New requirements require energy saving. In cold areas, the heat lost through gaps in doors and windows accounts for about 25% of the total heating heat consumption.

[0003] For example, a patent with a publication number of CN213359696U discloses a door and window locking and positioning device, which relates to the field of door and window technology, including a window frame, a first sliding groove is opened in the window frame, the top of the inner side of the window frame is fixedly connected to the first rotating seat, the first rotating seat is rotatably connected to the first rotating shaft, the first rotating shaft is fixedly connected to the glass window frame, a glass window mechanism is provided in the glass window frame, the inner side of the glass window frame is fixedly connected to the first locking mechanism, the inner bottom of the glass window frame is fixedly connected to the angle adjustment mechanism, and the angle adjustment mechanism is fixedly connected to the second locking mechanism.

[0004] Through the above configuration, the invention described in the prior art can realize the opening and closing of the glass window by setting the glass window mechanism, thereby achieving a better ventilation effect, can realize the locking of the glass window by setting the first locking mechanism, can realize the adjustment of the opening angle of the glass window frame by setting the angle adjustment mechanism, and can realize the locking and positioning of the glass window frame by setting the second locking mechanism, thereby increasing the efficiency of door and window locking and positioning, and reducing the labor cost. However, the door and window locking and positioning device of the prior art solution has the following defects during operation:

[0005] In the above device, when adjusting the angle of the glass window, it is necessary to use external tools to adjust the locking bolt, and then rotate the glass window. When the glass window is adjusted to a suitable angle, it is necessary to adjust the locking bolt again using external tools, so as to achieve the locking and positioning of the door and window. As a result, the process of using and adjusting the glass window is troublesome and inconvenient. Utility Model Content

[0006] The utility model aims to provide a door and window locking and positioning device, which is mainly used to solve the complicated technical problem of adjusting glass windows in the prior art.

[0007] In order to solve the above technical problems, the utility model provides the following technical solutions:

[0008] A door and window locking and positioning device comprises a window frame, wherein a glass frame is rotatably connected between the inner side walls of the window frame, the inner side walls of the window frame are provided with sliding grooves, the inner side walls of the sliding grooves are slidably connected with sliders, the ends of the sliders are fixedly connected with a first connecting plate, the side walls of the first connecting plate are rotatably connected with a connecting rod, the other end of the connecting rod is rotatably connected with the side walls of the glass frame, a plurality of first plug holes are symmetrically provided on the side walls of the window frame, and the first plug holes are connected with the sliding grooves, a cavity is provided inside the window frame, an adjusting component is rotatably connected to the inner side walls of the cavity, the side walls of the first connecting plate are fixedly connected with a second connecting plate, and the side walls of the second connecting plate are provided with a limiting component.

[0009] The working principle and beneficial effects of the utility model:

[0010] 1. Working principle: The structure of the door and window locking and positioning device in the utility model is similar to the existing door and window locking and positioning device structure. For example, the patent with announcement number CN213359696U discloses a door and window locking and positioning device. The main improvement of the utility model is that when the angle of the glass frame needs to be adjusted, the device first rotates the adjustment component to make the slider unrestricted, and then pushes the glass frame to make the glass frame rotate on the inner wall of the window frame. During the rotation of the glass frame, the connecting rod and the first connecting plate rotate. As the glass frame rotates, the first connecting plate will drive the slider to slide upward along the inner wall of the slide groove. When the glass frame rotates to a suitable angle, the limiting component is adjusted to make the limiting component enter the interior of the first plug hole, thereby limiting the slider, so that the glass frame can always remain in an open state.

[0011] 2. Beneficial effects:

[0012] The prior art solves the technical problem of locking the glass window, but the prior art has the technical problem of being cumbersome to adjust the glass window. The present invention, by means of the setting of the adjustment component, prevents the glass frame from rotating due to external force, thereby preventing pets or children from opening it easily, which poses a serious hidden danger to the safety of children and pets. By setting the limit component, the glass frame can be limited when it is opened to a suitable angle, so that the glass frame can always remain in an open state, thereby achieving the technical problem of locking and positioning the doors and windows.

When the glass frame needs to be opened, the gear is rotated and the two tooth plates are driven simultaneously by the gear. During the rotation of the gear, the two tooth plates are brought close to each other, and during the movement of the gear plate, the movable plate is driven to slide inside the cavity, so that the plug rod is disengaged from the second plug hole, so that the slider is unrestricted, and then the glass frame is pushed to rotate on the inner wall of the window frame, thereby quickly completing the opening of the glass frame.

[0014] Preferably: a rotating shaft is fixedly connected to the side wall of the gear, and the rotating shaft passes through the side wall of the window frame, a turntable is fixedly connected to the end of the rotating shaft, and a rotating rod is fixedly connected to the eccentric part of the turntable. When the gear needs to be rotated, the turntable is driven to rotate by rotating the rotating rod, and finally the gear is driven to rotate by the rotating shaft, thereby achieving the purpose of convenience.

[0015] Preferably: the limit assembly includes a through hole opened in the side wall of the second connecting plate, the inner wall of the through hole is slidably connected with a pull rod, the side wall of the pull rod is sleeved with a spring, one end of the spring is fixedly connected to the side wall of the second connecting plate, and the other end of the spring is fixedly connected to the pull rod. When the glass frame rotates, the first connecting plate drives the second connecting plate to slide along the outer wall of the window frame. When the end of the pull rod coincides with the first socket, the pull rod enters into one of the first sockets under the action of the compression spring, and the cooperation between the pull rod and the first socket is utilized to limit the movement of the first connecting plate and the slider, thereby completing the locking and positioning of the door and window.

[0016] Preferably: a rectangular hole is formed on the side wall of the first connecting plate, and a baffle is slidably connected to the inner wall of the rectangular hole. When the glass frame is rotated to a suitable angle, the baffle is pulled outward so that there is no conflict between the baffle and the pull rod, so that the pull rod is stuck into the interior of the first socket under the action of the compression spring.

[0017] Preferably, the side walls of the baffle are symmetrically fixedly connected with protrusions to prevent the baffle from being pulled out of the rectangular hole.

[0018] Preferably, the length of the tooth plate is much greater than the moving range of the moving plate, so as to prevent the tooth plate from being separated from the gear when the rotating gear is used to limit the sliding block through the insertion rod. BRIEF DESCRIPTION OF THE DRAWINGS

During the rotation of the gear 21, the two tooth plates 22 are brought close to each other, and the movable plate 1 is driven during the movement of the tooth plate 22. 6 slides inside the cavity 17, so that the insertion rod 15 is disengaged from the second insertion hole 12, so that the slider 11 is not restricted, and then the glass frame 7 is pushed to rotate the glass frame 7 on the inner wall of the window frame 2. During the rotation of the glass frame 7, the connecting rod 8 and the first connecting plate 3 rotate. As the glass frame 7 rotates, the first connecting plate 3 will drive the slider 11 to slide upward along the inner wall of the slide groove 1, and quickly complete the rapid opening of the glass frame 7.
