Abstract
Description
Technical Field
[0001] This invention relates to the field of building door and window hardware accessories, and in particular to a self-locking handle for doors and windows. Background Technology
[0002] Doors and windows are the most common structural elements in buildings, typically serving as entrances and exits, as well as ventilation and lighting openings. Handles, as essential components of doors and windows, are installed on the door and window sashes to enable opening and closing. With the development of modern architecture and the increasing demands of users, the security of doors and windows has become a growing concern. Current anti-theft measures involve adding lock cylinders to the handles, but this increases the cost of the handles, reduces their aesthetic appeal, and also poses a risk of key loss.
[0003] To address this issue, this application presents a self-locking handle for doors and windows. Summary of the Invention
[0004] To overcome the shortcomings of the prior art, the present invention provides a self-locking handle for doors and windows.
[0005] This invention is achieved through the following technical solution: A self-locking door and window handle, including a handle base, characterized in that: The handle seat has an elongated hole in the middle, through which the handle passes. The back of the handle seat has slide rails on both sides, and sliders are connected to the slide rails. The back of the handle seat has a C-shaped opening in the middle, and the handle is hinged at the C-shaped opening.
[0006] Furthermore, in order to better realize the present invention, a circular hole B is provided in the middle of the handle, a shaft A is inserted into the circular hole B, and the two ends of the shaft A are fixedly connected to the C-shaped opening. A circular hole A is provided at one end of the handle, a shaft B is inserted into the circular hole A, and a slider is slidably connected to both ends of the shaft B.
[0007] Furthermore, in order to better realize the present invention, slide rails A are provided at both ends of the slider, slide rails A slide along the slide rail on the back of the handle seat, and slide rails B are provided on both sides of the middle position of the slider, with slide rail B slidingly connecting shaft B.
[0008] Furthermore, in order to better realize the present invention, the slider is clamped on the handle seat by a screw, and a ring-shaped thin washer is provided at the screw.
[0009] The beneficial effects of this invention are as follows: The handle structure of this invention is simple. The self-locking function can be achieved by the cooperation of the slide rail B on the slider and the handle. There is no need to use a lock cylinder, and there is no need to worry about the inconvenience caused by the loss of the key. Attached Figure Description

[0012] The technical solutions of the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only a part of the embodiments of the present invention, and not all of them. The components of the embodiments of the present invention described and shown in the accompanying drawings can generally be arranged and designed in various different configurations.
[0013] Therefore, the following detailed description of the embodiments of the invention provided in the accompanying drawings is not intended to limit the scope of the claimed invention, but merely to illustrate selected embodiments of the invention. All other embodiments obtained by those skilled in the art based on the embodiments of the invention without inventive effort are within the scope of protection of the invention.
[0014] Figures 1-5 As a specific embodiment of the present invention, this embodiment is a self-locking door and window handle, such as... Figure 3 Figure 4 As shown, the handle base 1 has an elongated hole 11 in the middle, a slide rail 12 on the back, and a C-shaped opening 13 in the middle of the back.
[0015] like Figure 3 As shown, the handle 2 passes through the elongated hole 11 of the handle base 1, and a round hole A21 is provided at the other end, and a round hole B22 is provided in the middle position.
[0016] like Figure 4 As shown, slide rails A31 are provided at both ends of slider 3. Slide rails A31 slide along slide rail 12 on the back of handle seat 1, and slide rail B32 is provided in the middle position.
[0017] like Figure 3 Figure 4As shown, the shaft armor 4 passes through the round hole B22 of the handle 2, and both ends of the shaft armor 4 are fixed to the C-shaped opening 13 in the middle of the back of the handle seat 1.
[0018] like Figure 4 As shown, shaft B5 passes through the round hole A21 of handle 2, and both ends of shaft B5 slide along the slide rail B32 of slider 3.
[0019] like Figure 4 As shown, the gasket 6 is a ring-shaped thin sheet, which clamps the slider 3 onto the handle seat 1 by screws.
[0020] The specific implementation principle of this embodiment is as follows: When the lock is pried open from the outside, forcibly opening the window, slider 3 will experience a force to the right, such as... Figure 5 As shown, at this time, slider 3 applies a force to the upper right of shaft B5 through slide rail B32. This force is transmitted to handle 2 through the round hole A21. Since this force passes over the top of shaft A4, it causes handle 2 to rotate clockwise along shaft A4. Figure 2 As shown, to open the handle, the handle 2 needs to be rotated counterclockwise along the shaft 4. This force keeps the handle locked, achieving a self-locking function.
[0021] Finally, it should be noted that the above embodiments are only used to illustrate the technical solutions of the present invention and are not intended to limit it. Any other modifications or equivalent substitutions made by those skilled in the art to the technical solutions of the present invention, as long as they do not depart from the spirit and scope of the technical solutions of the present invention, should be covered within the scope of the claims of the present invention.
