Lift-and-slide door lock driver with opening and closing force self-adjusting function

Abstract

The invention relates to the technical field of building door and window drivers, and particularly discloses a lift-and-slide door lock driver with an opening and closing force self-adjusting function. The lift-and-slide door lock driver with the opening and closing force self-adjusting function comprises a sliding plate which penetrates through a fixed plate, and is characterized in that inclinedgrooves are formed in the two side edges of the fixed plate respectively, a fixed plate supporting seat corresponding to inclined groove positions is arranged on the side of the fixed plate; and a guide rod is arranged on the fixed plate supporting seat in a penetrating mode, a pressure spring is arranged on the guide rod in a penetrating mode, a threaded hole located above the guide rod is formed in the sliding plate, a sliding plate connecting seat is riveted to the threaded hole through sliding plate connecting rivets, and a fixing groove corresponding to the guide rod is formed in the sliding plate connecting seat. The lift-and-slide door lock driver with the opening and closing force self-adjusting function has the advantages that the structure is simple, the operation is convenientand the design is reasonable; and through the pressure spring deformation, when a door leaf is changed between an initial state, namely locked state, and a lifting state, namely opening state, power and resistance are provided respectively, so that the opening and closing force in operation with a handle is reduced, and the problem of fast rebound is solved.

Description

(1) Technical field [0001] The invention relates to the technical field of building door and window actuators, in particular to a lifting push-pull door lock actuator with the function of self-adjusting opening and closing force. (2) Background technology [0002] After the hardware is installed on the lifting sliding door for construction, when the sliding door lock is lifted by turning the handle, the handle will feel heavy in the lifting state due to the overweight of the door leaf, and the handle rebounds too fast during the landing process, which may injure people. (3) Contents of the invention [0003] In order to make up for the deficiencies of the prior art, the present invention provides a lifting push-pull door lock actuator with a simple structure, safe use, and firm fixation with the function of self-adjusting opening and closing force. [0004] The present invention is achieved through the following technical solutions: [0005] A lifting push-pull door lock ...

AI Technical Summary

Problems solved by technology

[0002] After the hardware is installed on the lifting sliding door for construction, when the sliding door lock is lifted by turning the handle, the lifting state will feel heavy due to the heavy door leaf, and the handle rebounds too fast during the landing process, which may cause injury to people.
