Description

Technical Field

[0001] The utility model relates to the technical field of screen window locks, in particular to a handle type screen window lock. Background Art

[0002] Screens refer to nets that block mosquitoes, flies and insects. The main function of screens is to prevent mosquitoes from entering the house. For safety reasons, screens are equipped with screen locks to ensure people's safety.

[0003] In the related technology, a screen lock (announcement number: CN216617164U) was found through searching. When in use, a reset spring with a reset function is used to press the plug into the profile to fix it. There is no exposed screw hole, the appearance is neat and beautiful, there is an external key, and it is unlocked by the key, which has higher protection for children. When the handle is in the open state, the tail end of the handle is in contact with the panel at the hanging part, which can share the pulling force of the rotating shaft and reduce the force on the rotating shaft, which can greatly improve the service life of the handle. By pulling out the screw, the plug is driven back and the reset spring is compressed, so that the screen lock can be removed from the door and window, and it is easy to disassemble after installation.

[0004] However, in the above-mentioned use process, a key is needed to open the screen lock. If the screen lock cannot be opened due to the loss of the key, indoor ventilation may be restricted, especially in the hot summer, which may make the room stuffy and affect the living or working environment. At the same time, if the key is lost, it may be necessary to ask a professional to open the screen lock, which may incur additional maintenance costs. In addition, if the screen lock is seriously damaged, the entire device may need to be replaced, which will further increase the cost and make it inconvenient to use. In view of this, we have introduced a handle-type screen lock. Utility Model Content
