Internal rotating structure of push-pull lock

Abstract

The invention discloses an internal rotating structure of a push-pull lock. The internal rotating structure comprises a cover plate, a handle, a swing mechanism, a transmission sliding block, a rack and a baseplate; the cover plate is fixedly arranged, and defines a lock body shell with the baseplate; the rack which is in engaged transmission with a gear on a square seat of the push-pull lock canbe slidably installed on the inside wall of the baseplate at a set distance; the rack is fixedly connected to the transmission sliding block, and the cover plate is provided with a hollow part; the side wall, facing the cover plate, of one end of the handle is provided with a lug boss, and the lug boss at one end of the handle comes into close contact with the outside surface of the cover plate, and covers the hollow part on the cover plate completely; the swing mechanism is rotatably installed on the cover plate, and the transmission sliding block can be driven by one end of the swing mechanism to slide; and the other end of the swing mechanism penetrates the hollow part on the cover plate, and is fixedly connected to the lug boss at one end of the handle. The internal rotating structureis beautiful in appearance, and a clearance between the handle and the cover plate is extremely small; the relative rotation is smooth, and dust is not liable to accumulate; and the internal rotatingstructure is not stuck even after long-time use.

Description

technical field [0001] The invention relates to a push-pull lock, in particular to an internal rotation structure of the push-pull lock. Background technique [0002] Push-pull door lock is a common door lock. Its interlocking structure is completely located inside the lock body shell formed by the cover plate and the bottom plate. The handle is connected to the interlocking structure. By turning the handle, the inner bar seat of the lock is rotated to realize the function of opening the door. Due to the above structure, a larger space is required between the cover plate and the bottom plate of the door lock to accommodate the above-mentioned interlocking structure, and a protrusion is often formed on the lock body. In order to achieve unrestricted rotation of the handle and no jamming, it is necessary to reserve a certain gap between the handle and the cover plate, which makes the gap obvious to the outside, poor aesthetics, and long-term use is easy to accumulate dust, res...
