Abstract

The invention discloses a novel door lock, comprising an outer handle and an inner handle, wherein a door lock body is arranged between the outer handle and the inner handle, two ends of the door lock body are respectively provided with a movable part, and the outer handle and the inner handle are detachably connected with the door lock body through the movable parts. According to the novel door lock disclosed by the invention, the handles can be replaced according to requirements or preferences of users; when the handles are arranged, openings on the handles only need to be clamped and assembled onto first protrusions arranged at top ends of main bodies of movable connecting pieces; and when the handles are detached, the first protrusions are pressed downwards and move downwards under the action of elastic pieces at the lower parts of the main bodies of the movable connecting pieces, so that the handles are separated from the main bodies of the movable connecting pieces. The novel door lock is convenient to detach and use, thereby having a favorable application prospect.

Description

A kind of new door lock

Technical field

The present invention relates to the door lock assembly technical field, particularly relate to a kind of new door lock that is convenient for changing handle.

Background technology

At present; The door lock that is used for the switch door on family or office and other places generally is to carry out switch by being rotatably provided in the inside and outside door locking handle of door; Adopt the door lock of this structure mainly to comprise inside and outside handle, be arranged on the door lock body between the inside and outside handle and door lock is fixed on the fixed part on the door; Generally all be to adopt specific supporting design between the handle of conventional door lock and the door lock body; In case handle damages or the user is dissatisfied to its design pattern; Just need change a whole set of door lock; Be that traditional product can not need change handle according to the user; This has limited the promotion and application of handle door lock sub-unit on the one hand greatly; Its global design not enough hommization that also seems on the other hand; Bring inconvenience to the user; In view of above-mentioned defective, be necessary the design of existing door lock is proposed new improvement.

Summary of the invention

To the problems referred to above, the invention provides and a kind ofly can change handle and new door lock easy to install by user's demand.

The technical scheme that the present invention is adopted for its technical problem of solution is:

A kind of new door lock; Comprise outdoor handle and inner handle; Be provided with the door lock body between said outdoor handle and the inner handle, it is characterized in that: the two ends of said door lock body all are equipped with a movable part, and outdoor handle and inner handle are removably connected through said movable part and door lock body.

As further improvement to such scheme; Said movable part comprises active connection body and elastic component; The top of active connection body is provided with first convexity; One end of said door lock body is a tubular structure; Tubular structure is provided with and clamps the first first protruding through hole; Also be provided with the handle through hole that matches and clamp with first convexity on outdoor handle and the inner handle, said elastic component is arranged in the tubular structure, and the active connection body is arranged between tubular structure inwall and the elastic component.

Further, the both sides of said active connection body are provided with second convexity, and tubular structure is provided with and clamps the second second protruding through hole, and the aperture of said second through hole is greater than the second protruding length.

Further, the said first protruding top is the globoidal structure that matches with the inwall of said outdoor handle and inner handle.

Further, said elastic component is bar shaped iron wire, steel wire or spring.

In addition, said active connection body is the semicircular structure of agreeing with mutually with the inwall of said tubular structure.

The invention has the beneficial effects as follows: the present invention is as a kind of new door lock; Can solve the conventional door lock model well fixes; The problem that disassembling, assembling and replacing is inconvenient; Because the two ends of door lock body all are equipped with a movable part; Outdoor handle and inner handle are removably connected through said movable part and door lock body; The present invention can change handle according to user's needs or hobby; When handle is installed; Only first convexity of opening on the handle and the setting of active connection body top need be clamped and get final product; When taking apart; Downwards by first convexity; Because the effect of active connection body bottom elastic component, first convexity can move down, and makes handle and active connection body be separated; Therefore easy disassembly possesses good prospects for application.
