Description

Technical Field

[0001] The utility model relates to the technical field of door and window handles, in particular to a door and window handle which is easy to replace. Background Art

[0002] A handle, also known as a pull handle or a handshake, refers to the place on an object where the hand is held, through which mechanical equipment and cabinet equipment can be held, operated or moved, and it is used to facilitate the opening of doors. It is a handle, handrail and other metal handles. It can be divided into plastic handles, hardware handles, wooden handles, alloy handles, etc. according to the material. Door and window handles refer to auxiliary equipment used to open and close doors and windows, which are usually installed on the surface of doors and windows to facilitate the opening or closing of doors and windows.

[0003] There are many types of door and window handles on the market. They need to be installed on the surface of the door and window before use. The current installation method is mostly bolt connection. The connection holes on the handle surface are aligned with the connection holes on the door and window surface, and then the bolts are used to penetrate the connection holes to make the handles firmly installed. This requires the use of auxiliary tools to twist the bolts when disassembling the handles, which is often cumbersome, and the bolts are prone to slipping after repeated use, which can easily cause the handles to loosen.

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

[0013] 1. The existing door and window handles are mostly installed by bolt connection, so that the bolts need to be twisted when they are disassembled and assembled, which is often cumbersome, and the bolts are prone to slipping after repeated use. The utility model is provided with an installation mechanism, and the handle is plugged into the installation groove through the installation block, and the push block is pushed and the worm is rotated. Since the worm is meshed with the worm wheel, when the worm rotates, the worm wheel drives the smooth rod to rotate together, thereby driving the gear to rotate. Since the gear is meshed with the rack, when the gear rotates, the rack drives the limit block to be plugged into the limit groove, and the push block is loosened, so that the limit rod is plugged into the worm, so that the worm is limited. In this way, the handle is firmly installed without the use of bolts, which solves the problem of cumbersome installation of the handle;

[0014] 2. Existing door and window handles and connecting frames are usually welded, and the connecting frame is a single column, so that the distance between the handle and the window is fixed after installation. This often has limitations and is difficult to match different windows. The utility model is provided with an extension mechanism, and the card block is pulled out to separate the card block from the bayonet, and the handle is pulled out to increase the distance between the handle and the limit plate. The card block is released, so that the card block is reset under the action of the reset spring and engages with the bayonet, so that the handle is limited, thereby increasing the distance between the handle and the window, thereby improving the practicality of the device.
