One-way multi-point locking handle for doors and windows

Abstract

The invention provides a one-way multi-point locking handle for doors and windows. The one-way multi-point locking handle comprises a handle body, a handle base and a connecting part, wherein the handle base comprises a first shell, a second shell, a convex column hole, a containing chamber, a supporting device, a fixing shaft, a shifting block device and a locking tooth guide rail; the convex column hole runs through the first shell, so that the second sleeve is sleeved with the first shell; one end of the fixing shaft penetrates through the supporting device and the convex column hole in sequence and then is inserted into the connecting part to be fixedly connected with the connecting part, and the other end of the fixing shaft is fixed to the supporting device; when the handle body is manually rotated, the fixing shaft rotates to drive the locking tooth guide rail and the shifting block device to simultaneously and horizontally move for unlocking or locking, and the handle body, theconnecting part, the first shell, the second shell, the fixing shaft, the locking tooth guide rail and the shifting block device are made of aluminum. The multi-point locking handle for the doors andthe windows is uniform and stable in transmission, the service life is long, assembling and positioning are simple and accurate, the manufacturing process is not complex, and the environment is protected.

Description

technical field [0001] The invention relates to the field of door and window accessories, in particular to a one-way multi-point lock handle used for doors and windows. Background technique [0002] Door and window handles are widely used as an important accessory of door and window structures. The door and window handles commonly used in the prior art include shift fork drive handles and square shaft drive handles. In the prior art, these two handle structures generally have complex manufacturing and assembly processes. For example, the common Most square shaft handles are assembled with square drive shafts by riveting. The production and assembly process often limits the shape design and makes assembly extremely inconvenient. The current multi-point lock handle is to move the gear to drive the shift block by toggling the handle, and the shift block drives the transmission rod to move back and forth, and the locking nails fixed at both ends of the transmission rod are sent...

Problems solved by technology

The door and window handles commonly used in the prior art include shift fork drive handles and square shaft drive handles. In the prior art, these two handle structures generally have complex manufacturing and assembly processes. For example, the common Most square shaft handles are assembled with square transmission shafts by riveting. The production and assembly process often restricts the shape design and makes assembly extremely inconvenient.

The current multi-point lock handle uses the handle to make the gear drive the shift block to move, and the shift block drives the transmission rod to move back and forth, and the locking nails fixed at both ends of the transmission rod are sent into or out of the lock on the door and window frame, thereby realizing However, most of the current multi-point lock handles are limited by the imperfection of the existing technology, and the size of the parts is not processed accurately, so that the transmission gap between the gear and the dial block varies from time to time, resulting in a multi-point lock. The friction resistance of the handle transmission increases, and the transmission is uneven and unstable, thus reducing the service life of the product

For the positioning of rotating structures such as gear shafts of conventional handles, two-bead positioning, rubber ring convex point positioning or side spring top positioning are generally used in the prior art. The handle is prone to axial looseness and horizontal swing, and the longer the service life of the handle The looser and the fixed-point positioning is inaccurate; moreover, some handle caps with two-bead positioning structure cannot be rotated 360 degrees, which is very inconvenient to operate

In addition, most of the existing door and window handles are made of zinc alloy. Zinc alloy has problems such as high cost, complicated manufacturing process, environmental pollution during the manufacturing process, etc. Therefore, a new technical solution is urgently needed to solve the above problems
