Description

Technical Field

[0001] The present invention relates to the technical field of doors and windows, and particularly to a handle positioning structure and a door and window lock. Background Art

[0002] The door and window handle is an important component for controlling the opening and closing of doors and windows. Generally, two screws are fixed on the existing handle. The screws pass through the profile and are threadedly connected to the moving unit (or actuator). To ensure the firm connection between the handle and the moving unit, a positioning plate is used for limiting and fixing between the two. The positioning plate is provided with a limiting post and several through holes. The limiting post passes through the profile and inserts into the limiting hole of the moving unit for limiting, and the through holes are used for passing the screws and the output shaft on the handle. That is to say, in order to achieve a better fixed connection, at least five holes are required on the moving unit for the screws, the limiting post, and the output shaft to insert. This positioning plate structure results in more holes to be opened on the moving unit for cooperation, increasing the manufacturing process and manufacturing time of the product, and also reducing the aesthetics of the product. Summary of the Invention

[0003] Based on this, in view of the above problems, it is necessary to provide a handle positioning structure to simplify the existing positioning structure, which can not only achieve the limitation of the moving unit but also be fixedly connected to the handle, reduce the number of openings on the moving unit, facilitate the simplification of the manufacturing process, reduce the manufacturing time, and increase the aesthetics of the product.

[0004] A handle positioning structure includes:

[0005] A positioning plate, on which a first through hole and a second through hole are provided, and the first through hole is used for passing the output shaft of the handle;

[0006] A limiting post, which includes a limiting part, a clamping part, and a connecting part. The clamping part is fixed at one end of the limiting part, and the connecting part is arranged at the end of the clamping part away from the limiting part; the limiting part inserts into the limiting hole of the moving unit for limiting, the clamping part abuts against the positioning plate, and the connecting part is fixedly connected to the handle through the second through hole.

[0007] The above handle positioning structure cleverly combines the limiting component and the connecting component into one on the existing positioning structure, limits at one end and connects at the other end, correspondingly reducing the number of openings on the moving unit, facilitating the simplification of the manufacturing process and manufacturing time of the parts, and also increasing the aesthetics of the product.

[0008] In one embodiment, the limiting portion and the connecting portion are disposed on two sides of the clamping portion. The connecting portion is a threaded post, and a threaded hole matching the threaded post is provided on the handle. The threaded post passes through the second through hole and is threadedly connected to the threaded hole. During installation, the threaded post on the limiting post is screwed into the threaded hole formed in the handle, thereby realizing the connection between the handle positioning structure and the handle.

[0009] In one embodiment, the connecting portion is an internal threaded hole, which is provided on the clamping portion and extends towards the limiting portion. A screw matching the internal threaded hole is provided on the handle. The screw passes through the second through hole and is threadedly connected to the internal threaded hole. During installation, the limiting post is rotated to screw the screw on the handle into the internal threaded hole, thereby realizing the connection between the handle positioning structure and the handle.

[0010] In one embodiment, the limiting post is of an integral structure.

[0011] In one embodiment, a notch for circumferentially and fixedly connecting with an adjusting tool is provided at one end of the limiting portion away from the clamping portion. To rotate the limiting post, simply place a matching adjusting tool (such as a screwdriver) against the notch and rotate it.

[0012] In one embodiment, the axis of the notch is coaxially arranged with the axis of the limiting portion.

[0013] In one embodiment, the notch is hexagonal, square or straight-shaped. The shape of the notch can be set according to the situation.

[0014] In one embodiment, the number of the first through holes is 1, the number of the second through holes is 2, and the second through holes are disposed on two sides of the first through hole. The center of the first through hole can be set on the connecting line of the centers of the two second through holes, or can be set at a position close to this line.

[0015] On the one hand, the present invention further provides a door and window lock, including:

[0016] The above-mentioned handle positioning structure;

[0017] A motion unit, the motion unit includes a fixing portion, a transmission gear and a sliding portion. The sliding portion is slidably inserted on the fixing portion. The transmission gear is rotatably installed between the fixing portion and the sliding portion. The transmission gear meshes with the sliding portion, and the rotation of the transmission gear causes the sliding portion to slide on the fixing portion. A limiting hole and a connecting hole are provided at one end of the motion unit close to the handle positioning structure. The limiting post on the handle positioning structure is inserted into the limiting hole for limiting;

[0018] Handle, the handle includes a rotating handle and a fixed seat, the rotating handle can rotate around the axis of the fixed seat, an output shaft is fixed on the rotating handle, and the output shaft sequentially passes through the fixed seat, the first through hole, and the connecting hole and is circumferentially fixedly connected to the transmission gear.

[0019] For the above-mentioned door and window lock, adopting the handle positioning structure of the present invention simplifies the structure of the product and is beneficial to improving the installation efficiency of the product.

[0020] In one embodiment, the output shaft is a hexagonal column.

[0021] Compared with the prior art, the present invention has the following beneficial effects:

[0022] The handle positioning structure of the present invention cleverly combines the limiting component and the connecting component into one on the existing positioning structure, with one end for limiting and the other end for connecting. Correspondingly, the number of openings on the moving unit is reduced, which is beneficial to simplifying the manufacturing process and production time of parts, and also increases the aesthetic degree of the product.

[0023] For the door and window lock of the present invention, adopting the above-mentioned handle positioning structure simplifies the structure of the product and is beneficial to improving the installation efficiency of the product. Description of the Drawings
