Single point lock with improved structure

Abstract

The invention discloses a single-point lock with an improved structure. The single-point lock comprises a lock body provided with a square-tongue portion and an inclined-tongue portion. The square-tongue portion comprises a lock cylinder, a square tongue and a square-tongue extension transmission component. The inclined tongue portion comprises a lever handle, an inclined tongue and an inclined-tongue extension transmission component. The square-tongue extension transmission component is in connection and linkage with the inclined-tongue extension transmission component through a linkage driving block, and contraction of the square tongue and the inclined tongue is controlled by the lock cylinder. Compared with the prior art, the single-point lock has the advantages that the square-tongue portion and the inclined-tongue portion are matched in a linkage mode through the linkage driving block, so that the lock cylinder can control contraction of the square tongue and the inclined tongue, one-step in-place operation can be realized and operation convenience is improved; meanwhile, the single-point lock is simple and compact in overall structure, easy to assemble, practical and reliable.

Description

Technical field [0001] The invention relates to a handle lock, belonging to the technical field of locks, in particular to a single-point lock with an improved structure. Background technique [0002] In the prior art, the door and window locks have various styles and different functions. For example, the handle lock is to drive the lock tongue of the lock body to rotate by turning the handle to realize unlocking or locking. Generally, the handle lock includes a lock body, the lock body is provided with a square tongue part and a diagonal tongue part, the lock core of the square tongue part drives the square tongue to expand and contract through the square tongue telescopic transmission part, and the handle of the diagonal tongue part is through the diagonal tongue telescopic part Drive the inclined tongue to expand and contract, thereby realizing the opening and closing of doors and windows. The handle lock of this kind of structure is very popular among users because of its s...

Problems solved by technology

[0003] However, the square tongue and the oblique tongue of this type of handle lock in the prior art are separately and independently controlled, and there is no structure that can realize the interlocking action of the square tongue and the oblique tongue, and it is impossible to realize one-step control, such as through the lock cylinder Simultaneously control the retraction of the square tongue and the oblique tongue, etc. Therefore, this patent application is an improvement aimed at the above technical problems, in order to achieve one-step control in place and further improve the convenience of control
