Abstract
The utility model relates to a break-prevention multidirectional multifunctional lock core, which includes a lock core body consisting of a cylinder and a longitudinal bulge at the excircle of the cylinder. A dial wheel is positioned in the middle of the cylinder, and the dial wheel is matched with the cylinder rotatably. A lock cylinder is positioned in the cylinder; a radial ball hole is formed in the lock cylinder; a ball and a spring are arranged in the ball hole; two key holes are formed in the longitudinal lock cylinder and the dial wheel; and the two key holes are corresponding with each other. The lock core is characterized in that a hard alloy bar is arranged on the longitudinal outer side of the longitudinal bulge. The hard alloy bar is formed by stacking a middle layer and two surface layers, wherein, the middle layer is a steel plate bar formed by stamping and hardening a manganese (Mn) steel plate; and the two surface layers are made of stainless steel plate bars. With the adoption of the lock core, the lock core body is difficult to be broken, though a thief plans to damage the lock core, the thief has less possibility of succeeding. Therefore, the lock core is suitable for mortice door locks.
Description
Technical field
The present invention relates to a kind of lock core.Specifically, be to have the anti-multidirectional and multifunctional lock core that interrupts function, be applicable on the mortise door lock.
Background technology
At present, lock core body used on the various mortise door locks is all long, and its thumb wheel that links to each other with dead bolt all is installed in the centre of lock core body.For ease of thumb wheel is installed, the intermediate cylindrical part of lock core body need be slotted again, makes that its longitudinal strength is lower, and when meeting the robber and destroying, lock core body is easily interrupted, and the robber succeeds easily.
Summary of the invention
The problem to be solved in the present invention provides a kind of anti-breaking multi-aspect multi-functional lock core, adopts this lock core, and when meeting the robber and destroying, lock core body is difficult for being interrupted, and the robber is difficult to easily succeed.
For addressing the above problem, take following technical scheme:
Anti-breaking multi-aspect multi-functional lock core of the present invention contains lock core body, and this lock core body is made up of the vertical projection on cylinder and the cylinder cylindrical, and the centre of cylinder has thumb wheel and the two to be rotatable shape cooperation.Lock gall is arranged in the cylinder, radially pellet shot from a slingshot hole is arranged on the lock gall, radially in the pellet shot from a slingshot hole pellet shot from a slingshot and spring are arranged; On the vertical and thumb wheel of lock gall keyhole is arranged all, and the keyhole on the two is corresponding.Be characterized in that vertically there is the carbide alloy bar vertical outside of projection.This carbide alloy bar is to be stacked by intermediate layer and two surface layers to form.Intermediate layer wherein is the lath of making through punching press, quenching with manganese steel plate, and two surface layers are the stainless steel lath.
Take such scheme, have the following advantages:
Because the present invention vertically is provided with the carbide alloy bar in the outside in vertical projection of lock core body, this carbide alloy bar is to be stacked by intermediate layer and two surface layers to form.Intermediate layer wherein is the lath of making through punching press, quenching with manganese steel plate, and hardness is higher, is difficult for being interrupted.And two surface layers are the stainless steel lath, have stronger toughness, also are difficult for being interrupted.Therefore, by intermediate layer and two surface layers are set, make the intensity of lock core body improve greatly, when meeting the robber and destroying, lock core body is difficult for being interrupted, and the robber is difficult to easily succeed.
Description of drawings
Fig. 1 is an anti-breaking multi-aspect multi-functional lock core structural representation of the present invention;
Fig. 2 is the A-A cross-sectional schematic of Fig. 1.
The specific embodiment
As Fig. 1 and shown in Figure 1, anti-breaking multi-aspect multi-functional lock core of the present invention contains lock core body, and this lock core body is made up of vertical protruding 6 of cylinder 2 and cylinder 2 cylindricals one side.The centre of cylinder 2 is provided with and is rotatable shape between thumb wheel 1 and the two and matches.By middle cover 10 lock gall 7 is installed in the cylinder 2, all is processed with radially pellet shot from a slingshot hole on lock gall 7 and the middle cover 10.Described radially pellet shot from a slingshot hole has four, these four radially the pellet shot from a slingshot hole along circumferentially being on the upper semicircumference that equidistantly is arranged in lock gall 7.Pellet shot from a slingshot 8 and spring 9 radially all are installed in the pellet shot from a slingshot hole.On the vertical and thumb wheel 1 of lock gall 7 keyhole that cooperates with key 3 is arranged all, and the keyhole on the two is corresponding.Vertically vertical outside of projection 6 is provided with carbide alloy bar 4.
For ease of installing and fixing, on vertical outside sidewall of vertical projection 6, be processed with longitudinal fluting, described carbide alloy bar 4 embeds in these longitudinal flutings, and fixes with pin 5.
For further improving the anti-ability of interrupting of lock core body, described carbide alloy bar 4 adopts and stacks the three layer construction that forms by intermediate layer and two surface layers.The intermediate layer is adopted with manganese steel plate and is made through punching press, quenching, and hardness is higher, can improve the intensity of lock core body.Two surface layers all adopt the stainless steel lath, and the stainless steel lath has stronger toughness.So, improved lock core body greatly anti-ly interrupt, survivability.The destruction even fall among thieves, lock core body also are difficult for being interrupted.
