Description

Casement window hardware device and window with limit and security functions

technical field

The invention belongs to the technical field of locking and positioning of casement windows, and in particular relates to a hardware device and a window body of a casement window with positioning and security functions.

Background technique

At present, most of the existing casement windows do not have a convenient and reliable positioning function, nor can they effectively limit the opening angle, which easily leads to dangerous behaviors of users jumping out of the window. Although some casement windows adopt the structure of positioning through tie rods, in fact, this type of tie rods cannot be locked, and only rely on wind braces to form friction to restrict the degree of freedom of the window sash. In this case, if the external force is large There is still the possibility of wiggling or self-closing. After a long time of use, due to the wear of the sliding contact surface, it is easy to generate noise and difficult to locate. There are other problems in the existing casement windows with wind braces. For example, the wind braces are located on both sides of the sash and close to the hinge (hinge) end. Short, the compressive and tensile strength becomes weaker, so the support strength is limited, and it is easy to loosen. In the prior art, even if the pull rod of the casement window is transferred to the other side of the sash opposite to the hinge (hinge), it is simply positioned by frictional sliding, which cannot solve the problem of positioning, opening and locking, and the security function Poor, can not effectively solve the safety problem of the user turning over the window. In addition, because it cannot be positioned and opened, the windows can only be fully opened at ordinary times, and the outer edge of the window sash protruding from the outside of the window sill is easy to scratch children, which poses a certain safety hazard.

Contents of the invention

The purpose of the present invention is to provide a casement window hardware device with position limiting and security functions to solve the common problems of casement windows in the prior art, such as the unreasonable structural design of the positioning cannot be locked and the positioning strength is insufficient. And the window, the casement window can be opened or locked by rotating the handle (handle) angle and matching a certain pulling force or pushing force. The open state can be positioned by the limit pull rod, or the limit pull rod can be temporarily abandoned to make the entire window sash fully open. .

In order to achieve the purpose of the above invention, the following technical solution is adopted: a hardware device for casement windows with limiting and security functions, including a handle base fixed on the side of the window sash, and a rotatable handle set on the handle base , and a shift fork arranged on the inner side of the handle fixing part that can translate up or down with the handle turning, and on the side of the window sash on the other side facing the hinge, there is also a slider matched with the shift fork, The limit guide rod is connected with the slider, and the guide structure for maintaining the vertical translation of the limit guide rod; the limit guide rod is provided with a vertical chute, and an elastic card is arranged on the upper part of the vertical chute; The side wall of the window frame corresponding to the limit guide rod is provided with a limiter, and a limiter pull rod is installed on the limiter through a revolving pin. Matching installation to the chute, the end of the sliding pin is provided with a flange to prevent it from falling out of the vertical chute; at the same time, the limiter is provided with a lock that can lock the closed limit pull rod tight bit.

The locking position may be that the locking position is respectively provided with positioning buckles above and below the limiter for preventing the limit pull rod from swinging freely.

The guide structure is provided with protruding strips on both sides of the limit guide rod and matching grooves on the side of the window sash to form a sliding fit guide structure.

The guide structure also includes an upper slide bar connected to the upper end of the limit guide rod and a lower slide bar connected to the bottom of the slide block. At the same time, an upper lock block and a lower lock block are fixed on the side of the window sash. Guide grooves are provided on the side, and guide ribs are provided on the side walls of the upper and lower slides, so that the guide ribs are located in the guide grooves to form a sliding fit guide structure.

The vertical chute on the limit guide rod consists of two parts. The upper vertical chute is set on the side of the limit guide rod and is integrated with the limit guide rod. The lower vertical chute (ring buckle) can be connected with the upper vertical chute. It is docked and fixed to the chute.

The ends of the upper slide bar and the lower slide bar are respectively equipped with lock heads.

A window with a limit and security function, including a window sash and a window frame, one side of the sash is installed on the window frame through a hinge, and the other side of the window sash opposite to the hinge is provided with the limit and security function. Functional casement window hardware device, the casement window hardware device includes a handle base fixed on the side of the window sash, a handle set on the handle base that can rotate, and a handle set inside the handle base that can rotate with the handle The shift fork that translates upward or downward is characterized in that: on the side of the window sash on the other side facing the hinge, there is also a slider matched with the shift fork, connected with the slider to limit the guide rod, and The guide structure that keeps the vertical translation of the limit guide rod; the limit guide rod is provided with a vertical chute, and an elastic card is provided on the upper part of the vertical chute; A limiter is installed on the limiter through a rotating pin. A sliding pin is arranged at the end of the limiter. The sliding pin is matched with the vertical chute, and the end of the sliding pin is set The flange prevents it from falling out of the vertical chute; at the same time, the limiter is provided with a locking position that can lock the closed limit pull rod.

The present invention has the following beneficial effects: 1. The present invention adopts a limiter located on the window frame to lock and fix the limit pull rod, and is suitable for casement windows, so that the locking structure is concealed inside the window frame without affecting the opening of the window. Body aesthetics. After locking, the two support points of the pivot pin and the locking position serve as a stable support structure. Compared with the structure of the existing casement window relying on the wind brace, the positioning effect of the present invention is more reasonable. 2. The handle provides a structure for translation up and down, relying on the translation of the limit guide rod and the elastic card to make the limit rod out of the opening of the limiter, and then relying on the reverse rotation of the handle to release the travel position, so that the limit rod can be disengaged Compared with the existing casement windows that rely on frictional positioning, the translational positioning structure adopted by the present invention provides a safe and convenient positioning function. 3. The special design of the chute part, usually the lower vertical chute and the upper vertical chute are movably docked and fixed to form a closed chute, preventing the user from disengaging the limit pull rod from the vertical chute, thereby preventing the entire window sash from being dangerous if fully opened. In case of emergency, the positioning column of the lower vertical chute can be pulled out quickly, so that the lower vertical chute is separated from the upper vertical chute, and the chute becomes semi-closed, and the limit rod is separated from the vertical chute. Make the entire sash fully open. the
