[0002] Doors and windows are the entrances and exits of a building, used to separate the interior from the exterior and to provide ventilation and lighting. Doors and windows typically consist of door leaves, window leaves, window frames, and hardware. Depending on different needs and uses, the types and materials of doors and windows also vary.

[0003] Chinese patent application number 202421051715.5 discloses a door and window locking and positioning device, including a window frame, a glass frame rotatably connected between the inner sidewalls of the window frame, a sliding groove on each inner sidewall of the window frame, a slider slidably connected to the inner sidewall of each sliding groove, a first connecting plate fixedly connected to the end of the slider, a connecting rod rotatably connected to the sidewall of the first connecting plate, and the other end of the connecting rod rotatably connected to the sidewall of the glass frame. Multiple first insertion holes are symmetrically opened on the sidewall of the window frame, and the first insertion holes communicate with the sliding grooves. This patent, through the setting of an adjustment component, prevents the glass frame from rotating due to external force, thereby preventing pets or children from easily opening it, which poses a serious safety hazard to children and pets. Through the setting of a limiting component, the glass frame can be limited when opened to a suitable angle, ensuring that the glass frame remains open, thus solving the technical problem of door and window locking and positioning.

[0004] In the aforementioned patent, gears and toothed plates are provided at the bottom of the window frame to drive the moving plate and the insert rod to move. After long-term use, the gears and toothed plates are prone to dulling, affecting the smoothness of the gear and toothed plate meshing transmission, which in turn can easily affect the opening and closing of the window frame. In addition, a baffle is inserted into the first connecting plate. When the baffle is not needed, it cannot be fixed, which can easily cause the baffle to be lost. Utility Model Content

[0005] To address the problems mentioned in the background section, this utility model provides a door and window locking and positioning device, which is easy to maintain and repair, and prevents loss.

[0006] To achieve the above objectives, this utility model provides the following technical solution: a door and window locking and positioning device, including a window frame, a glass frame rotatably connected inside the window frame, sliding plates slidably connected to both sides inside the window frame, a connecting rod rotatably connected between the sliding plates and the glass frame, a baffle inserted into the side wall of the sliding plate, a locking mechanism provided between the sliding plate and the window frame, a positioning mechanism provided inside the window frame, a connecting component provided between the sliding plate and the baffle, and a movable opening and closing component provided on the side wall of the window frame and outside the positioning mechanism.

[0012] Compared with the prior art, the beneficial effects of this utility model are:

[0013] 1. This utility model is equipped with a movable opening and closing component. When maintenance and repair operations are required on the positioning mechanism, the fixed screw is rotated to make it rotate and move along the top block. The rotation and movement of the fixed screw drives the fixed plate to rotate and move into the circular groove. Then, the two top plates move away from the fixed column. The movement of the top plates drives the movable plate and the positioning rod to move along the fixed column and the positioning groove respectively. When the two movable plates move away from each other and the positioning mechanism is exposed, the positioning mechanism can be maintained and repaired, which is convenient for operators.

[0014] 2. This utility model is equipped with a connecting component. The movement of the baffle drives the movement of the connecting block, and the movement of the connecting block drives the stretching of the connecting spring and the movement of the threaded column. After the threaded column moves through the through hole and passes through the L-shaped plate, the threaded cylinder is rotated and screwed to the end of the threaded column. The threaded cylinder and the threaded column can limit and fix the connecting block, and thus limit and fix the baffle, which facilitates the movement of the baffle and can prevent the baffle from detaching from the slide plate and being lost.

[0022] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0023] Example 1

[0024] Please see Figure 1-6The present invention provides the following technical solution: a door and window locking and positioning device, including a window frame 1, a glass frame 2 rotatably connected inside the window frame 1, sliding plates 5 slidably connected to both sides inside the window frame 1, a connecting rod 6 rotatably connected between the sliding plates 5 and the glass frame 2, a baffle 8 inserted into the side wall of the sliding plates 5, a locking mechanism 9 provided between the sliding plates 5 and the window frame 1, a positioning mechanism 4 provided inside the window frame 1, a connecting component 7 provided between the sliding plates 5 and the baffle 8, and a movable opening and closing component 3 provided on the side wall of the window frame 1 and outside the positioning mechanism 4.

[0025] Specifically, the movable opening and closing assembly 3 includes a movable plate 31, a top block 32, a top plate 34, a fixing member 35, and a fixing post 36. The top block 32 is fixedly connected to the inner wall of the window frame 1. The fixing posts 36 are fixedly connected to both sides of the top block 32. The top plate 34 is slidably connected to the periphery of the fixing posts 36. A round hole is provided on the top plate 34 at the position corresponding to the fixing post 36. The fixing member 35 is provided between the top plate 34 and the top block 32. The movable plate 31 is fixedly connected to one end of the top plate 34.

[0026] By adopting the above technical solution, when the positioning mechanism 4 needs to be maintained and repaired, the fixing effect of the fixing part 35 on the top plate 34 is released, and then the two top plates 34 are moved away from each other along the fixing column 36. The movement of the top plates 34 drives the movement of the moving plate 31. When the two moving plates 31 move away from each other and the positioning mechanism 4 is revealed, the positioning mechanism 4 can be maintained and repaired, which is convenient for operators.

[0027] Specifically, the fixing component 35 includes a positioning rod 351, a positioning groove 352, a circular groove 353, a fixing screw 354, and a fixing plate 355. The positioning rod 351 is fixedly connected to the side wall of the top plate 34. The positioning groove 352 is formed on the top block 32 at the position corresponding to the positioning rod 351. The fixing screw 354 is threadedly connected to the inside of the top block 32. The fixing plate 355 is fixedly connected to the end of the fixing screw 354 near the positioning rod 351. The circular groove 353 is formed on the side wall of the positioning groove 352 at the position corresponding to the fixing plate 355.

[0028] By adopting the above technical solution, after the positioning mechanism 4 is maintained and repaired, the two top plates 34 are moved to drive the two moving plates 31 to move and fit together. The positioning rod 351 moves and inserts into the positioning groove 352. Then, the fixing screw 354 is rotated to make it rotate and move along the top block 32. The rotation and movement of the fixing screw 354 drives the fixing plate 355 to rotate and move away from the circular groove 353. When the fixing plate 355 moves and fits the positioning rod 351, the rotation of the fixing screw 354 is stopped. The fixing plate 355 can be used to fix the positioning rod 351, thereby pressing and fixing the top plate 34 and the moving plate 31 to ensure the stability of the movement and fit of the two moving plates 31. The moving plate 31 can then be used to shield and protect the positioning mechanism 4.

[0029] Specifically, each of the two movable plates 31 has a semi-circular hole 33 at one end that is close to the other.

[0030] By adopting the above technical solution, after the two moving plates 31 move and fit together, under the action of the two semi-circular holes 33, the moving plates 31 can avoid affecting the positioning operation of the positioning mechanism 4.

[0031] In this embodiment, when ventilation is required by opening the glass frame 2 during the use of the door and window, the positioning mechanism 4 releases the positioning operation of the sliding plate 5, and then the sliding plate 5 is moved along the window frame 1. During the movement of the sliding plate 5, under the action of the connecting rod 6, the glass frame 2 can be rotated and opened. When the glass frame 2 is rotated and opened to a suitable angle, the movement of the sliding plate 5 is stopped, and then the baffle 8 is moved to the outer periphery of the sliding plate 5, so that the baffle 8 loses its limiting and blocking operation on the locking mechanism 9. Then, the locking mechanism 9 is used to lock the sliding plate 5, thereby limiting and fixing the glass frame 2, ensuring that the glass frame 2... To ensure stability during placement, when maintenance and repair of the positioning mechanism 4 are required after prolonged use, the fixing screw 354 is rotated to move along the top block 32. The rotation and movement of the fixing screw 354 causes the fixing plate 355 to rotate and move into the circular groove 353. Then, the two top plates 34 move away from each other along the fixing column 36. The movement of the top plates 34 causes the moving plate 31 and the positioning rod 351 to move along the fixing column 36 and the positioning groove 352 respectively. When the two moving plates 31 move away from each other and the positioning mechanism 4 is visible, the positioning mechanism 4 can be maintained and repaired, making it convenient for operators to operate.

[0032] Example 2

[0033] The difference between this embodiment and Embodiment 1 is that the connecting assembly 7 includes an L-shaped plate 71, a connecting spring 72, a connecting block 73, a threaded post 74, and a threaded cylinder 75. An L-shaped plate 71 is fixedly connected to the side wall of the slide plate 5 above the baffle 8. A connecting block 73 is fixedly connected to one end of the baffle 8 near the L-shaped plate 71. A connecting spring 72 is fixedly connected between the connecting block 73 and the slide plate 5. A threaded post 74 is fixedly connected to the side wall of the connecting block 73. A through hole is provided on the L-shaped plate 71 at the position corresponding to the threaded post 74. One end of the threaded post 74 is threadedly connected to the threaded cylinder 75.

[0034] Specifically, a guide slider is fixedly connected to one end of the connecting block 73 near the L-shaped plate 71, and a guide groove is provided on the inner side wall of the L-shaped plate 71 at the position corresponding to the guide slider.

[0035] By adopting the above technical solution, during the movement of the connecting block 73, the cooperation of the guide slider and the guide groove can provide guidance for the movement of the connecting block 73, thereby improving the stability of the movement of the connecting block 73.

[0036] In this embodiment, the movement of the baffle 8 causes the connecting block 73 to move, and the movement of the connecting block 73 causes the connecting spring 72 to stretch and the threaded column 74 to move. After the threaded column 74 moves through the through hole and passes through the L-shaped plate 71, the threaded cylinder 75 is rotated and screwed to the end of the threaded column 74. The threaded cylinder 75 and the threaded column 74 can limit and fix the connecting block 73, and thus limit and fix the baffle 8, which facilitates the movement of the baffle 8 and prevents the baffle 8 from detaching from the slide plate 5 and being lost.

[0037] The structure and principle of the positioning mechanism 4, which consists of a second insertion hole, a insertion rod, a moving plate, a cavity, a rotating rod, a turntable, a rotating shaft, a gear, and a toothed plate, have been disclosed in a door and window locking and positioning device disclosed in Chinese Patent Application No. 202421051715.5. Its working principle is as follows: A cavity is provided at the inner bottom of the window frame 1. A rotating shaft is rotatably connected to the inner side wall of the cavity. A gear is fixedly connected to the outer side wall of the rotating shaft. A turntable is fixedly connected to one end of the rotating shaft. A rotating rod is fixedly connected to the side wall of the turntable. Toothed plates mesh with both the upper and lower ends of the gear. The two toothed plates respectively engage with the cavity... The top of the inner sidewall of the cavity is slidably connected to the bottom of the lower sidewall. A movable plate is fixedly connected to the end of the toothed plate, and a plug rod is fixedly connected to the end of the movable plate. A second plug hole is provided on the slide plate 5 at the plug rod. In use, the rotating rod is first rotated to drive the turntable to rotate, and then the rotating shaft drives the gear to rotate. The gear drives the two toothed plates at the same time. During the rotation of the gear, the two toothed plates move closer to each other. During the movement of the toothed plates, the movable plate slides inside the cavity, thereby causing the plug rod to disengage from the second plug hole, releasing the positioning operation of the slide plate 5, and then pushing the glass frame 2.

[0038] The structure and principle of the locking mechanism 9, which consists of a spring, a pull rod, a first insertion hole, and a through hole, have been disclosed in a door and window locking and positioning device disclosed in Chinese Patent Application No. 202421051715.5. Its working principle is as follows: multiple first insertion holes are symmetrically opened on the side wall of the window frame 1, and a through hole is opened on the side wall of the sliding plate 5. A pull rod is slidably connected to the inner side wall of the through hole. A spring is sleeved on the side wall of the pull rod. One end of the spring is fixedly connected to the side wall of the sliding plate 5, and the other end of the spring is fixedly connected to the pull rod. When the glass frame 2 rotates to a suitable angle, the baffle 8 is pulled outward so that the baffle 8 and the pull rod no longer collide. When the end of the pull rod coincides with the first insertion hole, the pull rod enters the interior of one of the first insertion holes under the action of the compressed spring. The movement of the sliding plate 5 is restricted by the cooperation between the pull rod and the first insertion hole, thereby completing the door and window locking and positioning work.

[0039] The working principle and usage process of this utility model are as follows: When the glass frame 2 needs to be opened for ventilation during the use of the doors and windows of this utility model, the positioning mechanism 4 is released from the positioning operation of the sliding plate 5, and then the sliding plate 5 is moved along the window frame 1. During the movement of the sliding plate 5, under the action of the connecting rod 6, the glass frame 2 can be rotated and opened. When the glass frame 2 is rotated and opened to a suitable angle, the sliding plate 5 is stopped, and then the baffle 8 is moved to the periphery of the sliding plate 5. The movement of the baffle 8 drives the connecting block 73 to move. The movement of the connecting block 73 drives the connecting spring 72 to stretch and the threaded column 74 to move. When the threaded column 74 moves through the through hole and passes through the L-shaped plate 71, the threaded cylinder 75 is rotated and screwed to the end of the threaded column 74. The threaded cylinder 75 and the threaded column 74 can limit and fix the connecting block 73, and thus limit and fix the baffle 8, which facilitates the movement of the baffle 8.
