Abstract

The utility model discloses a nonmetal lock core spring lock with key quick replacement lock core. The lock core of the lock is made of non-metal materials, and a lock core clamping ring switch mechanism consisting of a support frame 5, a support frame cross rod 9, a rubber wheel 6 and a special-shaped steel sheet 7 replaces a lock core clamping ring clamp ring; the positioning groove of the lock tongue 8 is changed into an automatic control type special-shaped positioning groove, the clamping ring groove is changed into a symmetrical inclined plane, two sides of the front half plane of the lock tongue 8 are changed into semi-circular planes, and a half curved surface marble translocation protective sleeve 4 is added; the lock body 1 is additionally provided with the return spring 2, and the lock can completely replace the lock core 3 in a few seconds by a key, so that the aim of replacing a new lock is fulfilled. The lockset has high security, high safety, high stability and high economy.

Description

Cylinder lock with fast changable core

The utility model relates to the cylinder lock field, is the nonmetal lock core marble lock that a kind of available key is changed lock core fast.

Traditional cylinder lock is to make with precious metal.Losing of key, especially in many people turnover and the hotel of using, the transmission of place keys such as office, warehouse, lose composite its lock forfeiture insurance function that all may make, make the user not have the sense of security.General means to save the situation is to change lock again, wastes time and energy like this and uneconomical.For overcoming these defectives, " can arbitrarily change the cylinder lock head of lock core marble " that " removable lock core cylinder " that Chinese patent CN106426A discloses and Chinese patent CN8264036U disclose etc., these lock construction complexity, manufacturing procedure increases, and all be to adopt precious metal, be difficult to reduce cost, and change complicated.

The economic cylinder lock that the purpose of this utility model provides and a kind ofly save that precious metal, weight reduction, use are reliable, simple in structure, processing is simple and easy, can quick and convenient replacing lock core.

The purpose of this utility model is to realize like this; it is used for lock core with nonmetals and manufactures; using the snap ring of lock core afterbody instead lock core snap ring switching mechanism replaces; change the dead bolt locating slot of lock core afterbody into autocontrol abnormity locating slot; change annular groove into symmetrical inclined-plane; dead bolt first half plane is changed into the semi circular surface of symmetry; dead bolt semi circular surface vertical with the annular groove inclined-plane (90 °); and set up Hough curved surface pellet shot from a slingshot transposition protective sleeve; and act on lock core respectively; the lock body is set up the lock core return spring on one's body at lock.

The utility model is described in further detail below in conjunction with accompanying drawing:

Accompanying drawing 1 is a main sectional view of the present utility model;

Accompanying drawing 2 is the sectional view of bowing of the present utility model;

See accompanying

drawing

1,2, the utility model is made up of lock body 1, lock core return spring 2, lock core 3, Hough curved surface pellet shot from a slingshot transposition protective sleeve 4, bracing frame 5, rubber wheel 6, special-shaped steel disc 7, dead bolt 8, bracing frame cross bar 9, key 10.Dui Cheng bracing frame 5 wherein, rubber wheel 6, special-shaped steel disc 7, bracing frame cross bar 9 constitutes lock core snap ring switching mechanism, and rubber wheel 6 is fixed on the bracing frame 5 and the special-shaped steel disc 7 supporting-points outside, with fixing point-blank, abnormity steel disc 7 is a rotating fulcrum with two supporting-points of symmetric support frame inboard, with rubber wheel 8 is radius, effectively operating angle is 18 °-48 °, the head end of abnormity steel disc 7 can snap in the annular groove both sides (lock core location) of lock core 3 afterbodys when first duty, abnormity steel disc 7 two ends stress points and bracing frame 5 two ends stress point angles are zero, abnormity steel disc 7 matches with the symmetrical semi circular surface tail end on dead bolt first half plane when second duty; Folding one side of Hough curved surface pellet shot from a slingshot transposition protective sleeve 4 is provided with and plays the number and the corresponding pellet shot from a slingshot passage of distance of core pellet shot from a slingshot, Hough curved surface pellet shot from a slingshot transposition protective sleeve 4 is installed between lock core 3 and the lock body 1, it acts on lock core marble and lock body pellet shot from a slingshot exposed surface respectively when changing lock core, Hough curved surface pellet shot from a slingshot transposition protective sleeve 4 tail end oblique angles are consistent with the angle on lock core card annular groove symmetry inclined-plane; Lock core return spring 2 is arranged on lock body 1 front portion, and operating distance equates with lock core card annular groove width (distance).

The utility model and common spring lock are basic identical, for realizing changing fast the purpose of lock core, increased the snap ring switching mechanism at lock body 1 end and can make lock core 3 quickly dismantleds, terminal annular groove at lock core 3 partly changes symmetrical inclined-plane into, promote the snap ring switching mechanism forward for 390 ° with key 10 rotational lock cores, finish and tear lock core 3 functions open; Change the semi circular surface of symmetry on dead bolt 8 first half planes into, promote dead bolt 8 forward for 390 °, finish dress lock core 3 functions with key 10 rotational lock cores; All for guaranteeing that finishing quickly dismantled lock core 3 designs, its lock core 3 adopts reliable nonmetals to make handling ease, remarkable benefit for the bracing frame 5 that increases, rubber sheet wheel 6, special-shaped steel disc 7, bracing frame cross bar 9 and Hough curved surface pellet shot from a slingshot transposition protective sleeve 4 etc.

Claims
