At this time, one end of the hook moves along the movable groove on the side of the stopper, pushing When the door is released to the end, the stopper is hooked by the hook, the limiter is in the unlocked state, the limiter returns to the initial state under the reaction force of the torsion spring of the limiter, and the slider moves safely toward the arrow under the swing force of the door closer. Realize the closing of the door. This method reduces the metal collision sound that occurs when the door is closed, and the sliding of the slider drives the closing and opening of the door. At the same time, the design of the fixed block and the stop block eliminates the need for manpower to drive the door, and it is convenient greatly increase.

The above description is only an overview of the technical solution of the present utility model. In order to have a clearer understanding of the technical means of the present utility model and can be implemented in accordance with the content of the specification, the following is a detailed description of the preferred embodiment of the present utility model with accompanying drawings. Rear.
