Description

Technical Field

[0001] This utility model relates to the technical field of locking devices for doors and windows, and in particular to a lightweight interlocking locking device for doors and windows. Background Technology

[0002] Windows are essential components of a building, designed to allow light and air to enter the interior. Most windows today are outward-opening, allowing users to push and adjust the angle to maintain ventilation and allow sunlight in. However, because windows are among the weakest points in a building's security, window locking mechanisms are crucial. These mechanisms effectively enhance window security.

[0003] However, currently, window locking devices are mostly located in the middle of doors and windows, which makes them easily accessible to children, posing a safety hazard of children falling out when the window is opened. In addition, the locking devices used in doors and windows are relatively complex in structure. In view of these problems, a lightweight linkage locking device for doors and windows is proposed. Utility Model Content

[0004] In view of the above-mentioned technical problems, this utility model provides a lightweight door and window linkage locking device, which consists of a locking component and a linkage component. The overall structure is simple, and after locking, it effectively prevents children from opening the window and falling, thus enhancing safety.

[0005] To achieve the above objectives, the technical solution of this utility model is as follows:

[0006] A lightweight interlocking device for doors and windows includes a window frame, a window, and a handle. The window frame is mounted on a building wall, and the window is movably connected to the window frame via hinges. A handle for easy opening and closing of the window is installed on the inner side of the window. The device is characterized in that a locking component is installed on the window frame, and the locking component is connected to a linkage component to prevent child opening. The linkage component is installed inside the window frame.

[0007] The locking mechanism consists of a handle, a rotating shaft, an eccentric wheel, a pressing end, a locking pin, and a spring. The eccentric wheel is located in a mounting groove on the window frame. The rotating shaft is connected to an eccentric hole on the eccentric wheel. One end of the rotating shaft is connected to the handle, and the other end of the rotating shaft is mounted in the groove wall of the mounting groove via a bearing. A locking pin is located beside the eccentric wheel. The locking pin has a pressing end at its end that extends into the mounting groove, and a spring is fitted around the outside of the locking pin.

[0008] The window frame is provided with a through hole, and the side of the window is provided with a lock hole. The lock pin is adapted to both the through hole and the lock hole.

[0009] Furthermore, the contact surface on the extrusion end that contacts the eccentric wheel is configured as an arc-shaped structure.

[0010] Furthermore, a support rod is provided on the extrusion end, and the top of the support rod is inserted into a T-shaped groove provided on the window frame. The support rod not only supports the extrusion end, but also guides its movement.

[0011] The linkage assembly includes a locking rod, an operating rod, and limiting blocks. The lower end of the locking rod is inserted into a limiting groove on the eccentric wheel, and the upper end of the locking rod is fixedly connected to the operating rod. The operating rod is located in a moving groove on the window frame, and limiting blocks are provided on the inner walls of both sides of the moving groove.

[0012] Furthermore, the limiting block is configured as an arc-shaped structure.

[0013] Furthermore, the limiting block is made of rubber, which gives it a certain degree of elasticity. Pulling the lever up or down forcefully can move the locking lever up or down.

[0014] The beneficial effects of this utility model are:

[0015] The locking device designed in this utility model for locking windows has a simple overall structure. During operation, the eccentric wheel is controlled to rotate by turning the handle. The eccentric wheel presses the pressing end of the locking pin, so that the other end of the locking pin extends out from the through hole on the window frame and inserts into the lock hole of the window, thus locking the window.

[0016] This invention adds a linkage component. After the window is locked, pulling down the operating rod in the linkage component controls the locking rod to move down and insert into the limiting groove on the eccentric wheel, thus locking the position of the eccentric wheel. Even if a child touches the handle of the locking component, the window cannot be opened. Furthermore, the operating rod in the linkage component is located at the upper end of the window frame, which is high enough that children cannot reach it, thereby improving the safety performance of children indoors.

[0027] Example 1

[0028] like Figure 1As shown, window frame 1 is installed on the building wall, and window 2 is movably connected to window frame 1 via hinges. A handle 3 is installed on the inner side of window 2 to facilitate opening and closing the window. Locking components are installed on window frame 1, as well as a linkage component that can be connected to the locking post to prevent children from opening the window.

[0029] like Figure 3 and 4 The locking mechanism consists of a handle 41, a rotating shaft 42, an eccentric wheel 43, a pressing end 45, a locking pin 44, and a spring 46. The eccentric wheel 43 is located in a mounting groove on the window frame 1. The rotating shaft 42 is connected to an eccentric hole on the eccentric wheel 43. One end of the rotating shaft 42 is connected to the handle 41, and the other end is mounted in the groove wall of the mounting groove on the window frame 1 via a bearing. The locking pin 44 is located beside the eccentric wheel 43. The end of the locking pin 44 that extends into the mounting groove is provided with a pressing end 45, and a spring 46 is sleeved on the outside of the locking pin 44.

[0030] The contact surface of the pressing end 45 that contacts the eccentric wheel 43 is designed with an arc shape, and a support rod 451 is provided on the pressing end 45. The top of the support rod 451 is inserted into a T-shaped groove provided on the window frame 1. The support rod 451 not only supports the pressing end 45 and the locking pin 44, but also guides the movement of the pressing end 45 and the locking pin 44. The other end of the locking pin 44 is located in a through hole provided on the window frame 1.

[0031] like Figure 6 The side of window 2 is provided with a lock hole 21, and the lock pin 44 is adapted to the lock hole. Once the lock pin 44 is inserted into the lock hole 21 of window 2, the window 2 is locked.

[0032] like Figure 2 and 5 The linkage assembly includes a locking rod 51, an operating rod 52, and a limiting block 53. After the window 2 is locked, the lower end of the locking rod 51 is inserted into the limiting groove 431 provided on the eccentric wheel 43, and the upper end of the locking rod 51 is fixedly connected to the operating rod 52. The operating rod 52 is located in the moving groove 11 provided on the window frame 1, and the limiting blocks 53 are provided on the inner walls of both sides of the moving groove 11.

[0033] Furthermore, the limiting block 53 is designed with an arc-shaped structure and is made of rubber, which gives the limiting block a certain degree of elasticity. By pulling the operating rod up or down, the position of the locking rod can be moved up and down.

[0034] Example 2

[0035] When locking the window 2, this invention simply involves rotating the handle 41 to control the rotation of the eccentric wheel 43. The eccentric wheel 43 presses against the pressing end 45 of the locking pin 44, causing the other end of the locking pin 44 to extend from the through hole on the window frame 1 and insert into the lock hole 21 of the window 2, thus locking the window 2. After the window 2 is locked, by pulling down the operating rod 52 in the linkage assembly, the locking rod 51 is moved down and inserted into the limiting groove 431 on the eccentric wheel 43, thus locking the position of the locking rod 51 against the eccentric wheel 43. Even if a child touches the handle 41 of the locking component, the window 2 cannot be opened. Furthermore, the operating rod 52 in the linkage assembly is located at the upper end of the window frame 1, which is high enough that children cannot reach it, thereby improving the safety performance of children indoors.
