Description

Technical Field

[0001] The utility model relates to the technical field of latch fasteners, in particular to a simple and practical knob latch. Background Art

[0002] Latch fasteners are a crucial component of door and window security, typically consisting of a movable locking block and a fastener body that secures the locking block. Knob latches rotate to snap the locking block into the fastener body, and are typically installed horizontally between two sets of door panels. However, when used on folding doors with two panels at a 90-degree angle, commercially available latches are inoperable. Furthermore, existing knob latches lack flexibility, have limited overall stability, and are difficult to install. Utility Model Content

[0004] In order to solve the above technical problems, the present invention provides the following technical solutions: The present invention proposes a simple and practical knob latch, comprising a locking member and a buckle body member, a boss is provided on one side of the locking member, a rotating body is rotatably provided on the boss, a locking rod is provided at one end of the rotating body, and a limit block is provided at one end of the locking rod, a locking block is provided on the buckle body member, and a locking slot 1 and a locking slot 2 are provided on the locking block, and the locking slot 1 and the locking slot 2 are vertically arranged.

[0005] Preferred technical solution one: The boss is provided with a positioning convex ring and four groups of arc-shaped positioning grooves, one side of the rotating body is provided with a threaded column and two groups of positioning holes, the positioning holes are provided with support springs and steel balls, the threaded column is rotatably arranged in the positioning convex ring, and the steel balls are matched with the arc-shaped positioning grooves, and also includes a screw, which passes through the locking piece and is threadedly connected to the threaded column.

[0006] Preferred technical solution 2: The four groups of arc-shaped positioning grooves are evenly distributed with the positioning convex ring as the center.

[0007] Preferred technical solution three: The locking piece and the buckle body are both rectangular in design, with arc-shaped chamfers at both ends.

[0008] Preferred technical solution four: Both ends of the locking member and the buckle body are further provided with mounting holes for fixing the locking member and the buckle body on the door panel.

[0009] The utility model proposes a simple and practical knob latch, which has the following beneficial effects by adopting the above structure:

[0010] (1) The two sets of steel balls and four sets of arc-shaped positioning grooves are used to achieve stable rotation of the rotating body, and the 90-degree positioning support is stable and reliable. The overall structure is simple, finely matched, and easy to assemble;

[0011] (2) The locking block of the buckle body is provided with a slot 1 and a slot 2 which are arranged perpendicular to each other. When in use, the locking member and the buckle body can be fixed horizontally on two sets of door panels. At the same time, they can also be used to fix on two sets of folding doors at 90 degrees. The locking rod is engaged with the slot 1 or the slot 2 to achieve flexible locking, which is more applicable. BRIEF DESCRIPTION OF THE DRAWINGS
