Description

Technical Field

[0001] This utility model relates to the field of hardware profile technology, and in particular to an angle-adjustable safety anti-detachment limiting support link. Background Technology

[0002] Casement hinges, as a type of opening and closing connector with good stability, high adjustability, and wide applicability, are widely used in operable doors and windows. Currently, when installing casement hinges with door and window frame profiles, it is necessary to install spacers on the frame profiles before connecting them to improve the stability of the connection. Furthermore, tightening bolts during installation makes the process relatively complicated, and subsequent fine-tuning is also cumbersome, affecting installation efficiency. This also impacts the stability of the connection between the door / window frame and the casement hinge.

[0003] In view of the shortcomings of the aforementioned conventional angle-adjustable safety anti-detachment limit support link, the applicant, upholding the spirit of research and innovation and striving for excellence, and combining production practice with professional and scientific methods, proposes a practical solution, and therefore submits this application. Utility Model Content

[0004] The purpose of this utility model is to provide an angle-adjustable safety anti-detachment limiting support link in response to the existing technical situation. It has a reasonable design, simple structure, and realizes quick disassembly and installation functions.

[0005] An angle-adjustable safety anti-detachment limiting support link comprises: a bottom groove, a long link, a short link, and a sliding block. The sliding block is installed inside the bottom groove and moves along the slide rail of the bottom groove. The first end of the long link is hinged to the sliding block, and the last end of the long link is hinged to the short link. A quick-release plate is provided on the first end of the long link. One end of the quick-release plate is hinged to the long link by a rivet, and the other end of the quick-release plate is provided with a barb that is fastened to the connecting shaft between the long link and the sliding block.

[0006] Specifically, the top of the connecting shaft is provided with a limiting cap, and the middle of the connecting shaft is provided with two layers of rings, which are stepped.

[0007] Specifically, the two-layer ring consists of an upper collar and a lower retaining ring. The round hole at the beginning of the connecting rod long support is fitted into the upper collar, and the lower retaining ring is secured between the connecting rod long support and the sliding block.

[0008] Specifically, the quick-release clip's barb is engaged between the limiting cap and the upper collar.

[0009] Specifically, the sliding block is provided with a locking bolt, the bottom of which presses against the inside of the bottom groove, and the inside of the bottom groove is provided with an upwardly protruding locking block.

[0010] Specifically, the bottom of the sliding block is provided with a gap for the card block to pass through.

[0011] Specifically, the connecting rod short support has a notch on both the left and right sides, which can be inserted into the groove of the profile to effectively prevent it from falling off.

[0012] Specifically, the connecting rod support has an upwardly protruding reinforcing rib in the middle, which increases the strength and toughness of the entire connecting rod support.

[0013] The beneficial effects of this utility model are as follows:

[0014] The limit brace can adjust the window opening angle and can fix the window opening angle to 10 degrees or 30 degrees by means of screws or sliders; rotating the quick release plate to disengage it from the connecting shaft allows the connecting rod to be disassembled, making it convenient for construction workers to disassemble the doors and windows; the locking bolt restricts the displacement of the sliding block by pressing against the bottom groove, keeping the doors and windows at a certain angle.

[0020] The accompanying drawings are for illustrative purposes only and should not be construed as limiting this patent. To better illustrate this embodiment, some components in the drawings may be omitted, enlarged, or reduced, and do not represent the actual dimensions of the product. It is understandable to those skilled in the art that some well-known structures and their descriptions may be omitted in the drawings. The positional relationships described in the drawings are for illustrative purposes only and should not be construed as limiting this patent.

[0021] As attached Figures 1 to 4As shown, an angle-adjustable safety anti-detachment limiting support link comprises: a bottom groove, a long link, a short link, and a sliding block. The sliding block is installed inside the bottom groove and moves along the slide rail of the bottom groove. The first end of the long link is hinged to the sliding block, and the last end of the long link is hinged to the short link. A quick-release plate is provided on the first end of the long link. One end of the quick-release plate is hinged to the long link by a rivet, and the other end of the quick-release plate is provided with a barb. The barb is fastened to the connecting shaft between the long link and the sliding block, and the barb of the quick-release plate can fasten the connecting shaft.

[0022] In the above scheme, the top of the connecting shaft is provided with a limiting cap, and the middle of the connecting shaft is provided with two layers of rings. The two layers of rings are stepped and are divided into an upper collar and a lower retaining ring. The round hole at the end of the connecting rod long support is fitted into the upper collar, and the lower retaining ring is locked between the connecting rod long support and the sliding block. The barb of the quick release piece is locked between the limiting cap and the upper collar.

[0023] The diameter of the upper collar is smaller than that of the lower retaining ring. The lower retaining ring can be locked below the connecting rod support. The hole in the connecting rod support can be fitted onto the upper collar. The connecting rod support rotates around the upper collar. The quick-release plate is fastened to the upper section of the connecting shaft. The limit cap can lock the quick-release plate.

[0024] In the above-described scheme, the sliding block is equipped with a locking bolt, the bottom of which abuts against the inside of the bottom groove. The inside of the bottom groove has an upward-protruding locking block. The bottom of the sliding block has a gap for the locking block to pass through.

[0025] The sliding block is inserted into the slide rail on both sides of the bottom groove and moves back and forth along the slide rail. The locking bolt is installed on the sliding block through threaded connection. After the sliding block moves to the designated position, the door or window is opened to the appropriate angle. Then the locking bolt is rotated to push against the bottom of the slide rail and fix it on the slide rail.

[0026] In the above-described design, the short connecting rod has a notch on both sides, allowing it to be inserted into the groove within the profile, effectively preventing it from falling off. The long connecting rod has an upward-protruding reinforcing rib in the middle, a design that increases the strength and toughness of the entire long connecting rod.

[0027] Obviously, the above embodiments of this utility model are merely examples for clearly illustrating this utility model, and are not intended to limit the implementation of this utility model. Those skilled in the art can make other variations or modifications based on the above description. It is neither necessary nor possible to exhaustively describe all embodiments here. Any modifications, equivalent substitutions, and improvements made within the spirit and principles of this utility model should be included within the protection scope of the claims of this utility model.
