Description

Compact integrated handle lock

Technical Field

The utility model relates to an integrated handle lock, in particular to a compact integrated handle lock.

Background

With the transition from the frequent to simple and hidden development process of the home and the aesthetic concept of people integrating simplicity and beauty, the lock is used as a door matching, and also has undergone the evolution from a panel lock to a split lock and then to an integral lock. In order to adapt to the development of home furnishing, in recent years, people integrate a lock cylinder and a handle together, and an integrated handle lock is invented. The prior integral handle lock is characterized in that a front handle and a rear handle are fixedly connected together through a pair of opposite penetrating studs which are parallel to a square rod and are positioned on two sides of the square rod, therefore, the front handle seat is fixedly connected with the front handle, the rear handle seat is fixedly connected with the rear handle, and then the pair of opposite penetrating studs penetrate through the rear handle seat and are screwed into the front handle seat; in order to avoid exposing the stud head penetrating through the stud, a rear handle seat cover is also used for covering the rear handle seat.

At present, the industry specification of the domestic door mortise lock body is that the hole distance of the opposite-penetrating stud holes of the lock body is generally set to be 38-42 mm, the distance between the opposite-penetrating studs on the handle lock base is also generally 38-42 mm in order to adapt to the requirements of the lock body, and the corresponding hole distance of the opposite-penetrating studs and screws can smoothly pass when the lock is installed on a door leaf and the distance between the corresponding hole holes on the door leaf is also consistent with the distance between the opposite-penetrating studs; meanwhile, in order to completely hide the opening on the door leaf, the width of the common handle seat is not less than 50mm, so that the handle column part (the section of the column where the handle leans against the door leaf) of the conventional handle lock is not large, which is the main reason that the shape of the conventional handle lock is usually small and the base is large. In order to meet the requirements of beauty, in recent years, popular integrated handle locks have a part of shapes which are matched with the sizes of handle columns and handle seats, so that the integrated handle locks with bulky (namely heavy and large) handle columns are appeared on the market. Although the split lock mode is gradually canceled and the split lock mode is gradually closed to the integral lock at present, no clumsy integral type with the handle column and the base are consistent, or the base is much bigger than the handle column, and the split lock mode is not beautiful. In order to achieve the consistent size of the handle column and the base, the handle column is ensured to be small enough (the size of the handle column is not more than 28 mm) so as to meet the pursuit of people on simplicity and beauty.

Accordingly, there is a need for improvements to current integrated handle locks.
