Description

Technical Field

[0001] The utility model relates to the technical field of window sash positioning and limiting braces, and specifically to a limiting brace with adjustable angle. Background Technique

[0002] A window sash limiting brace is a device used for windows, and its main function is to support and limit the window sash, reducing the burden on the hinge, thereby extending the service life of the hinge. However, the existing window braces cannot restrict the movement between the pivotally mounted window panel (window sash) and the supporting window frame, that is, the window brace cannot keep the window sash at a certain opening angle, resulting in inconvenient use.

[0003] Most of the existing limiting braces on the market, when the window sash needs to be positioned after being opened, rotate the knob on the sliding code by hand or with a screwdriver to increase the friction between the knob and the sliding code, so as to position the window sash. When closing the window sash, loosen the knob again to enable the window sash to be closed. This process requires manual operation, and tightening or loosening needs to be repeated for both opening and closing, which is not convenient for operation. Therefore, there is an urgent need to improve a limiting brace with adjustable angle to solve the above problems. Content of the Utility Model

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

[0013] 1. This angle-adjustable limiting support, through its positioning mechanism, allows the sliding block to engage or disengage the retaining spring when the window sash is opened or closed. This structure is easy to operate, eliminating the need for manual knob rotation. The retaining spring structure, utilizing the contact between the two protrusions and the straight part of the retaining spring against the bottom groove wall, allows for a positioning force of up to 40N. This prevents the window sash from closing easily under external force, providing a certain degree of limiting effect, while still allowing for smooth closure under manual operation.

[0014] 2. This angle-adjustable limiting support, through the design of the angle adjustment mechanism, has multiple holes designed on the bottom groove, and the retaining spring can slide in the bottom groove. At the desired window sash opening position, the retaining spring is positioned using a cross-slot countersunk screw, which allows the window sash to be positioned at that angle, making the operation simple and quick.
