Abstract
The utility model relates to a double-security lock and key. At least a group of cone-shaped springs and magnetic springs are arranged in a lock, concave points and small magnetic sheets which correspond to the springs are arranged on the key corresponding to the cone-shaped springs and the magnetic springs, a lock care can be provided with a sheet-shaped key inserting hole or a cylindrical key inserting hole, the concave points and the small magnetic sheets are respectively arranged on both side faces or the circular peripheral surface of a sheet-shaped key, and the concave point and the small magnetic sheet can be crosswise arranged. A cylindrical key not only can increase the fastness of a key, but also can possibly reduce the weight of the key.
Description
The utility model relates to field of lockset, particularly a kind of dual safety lock and key.
The tapered end of selling on the market generally is equipped with taper of many groups or cylinder-shaped marble in tapered end and lock core at present, and for the tapered end of this kind structure, the robber is easy to by surreptitiously joining key or with the cleek of definite shape lock being opened.Also having a kind of on the market all is the tapered end of magnetic bullet in tapered end and lock core, and the also easy stolen key of joining of this kind tapered end is opened lock.Thereby the theftproof performance of these structure tapered ends is undesirable.
The purpose of this utility model is: a kind of theftproof performance that has magnetic bullet and taper pellet shot from a slingshot simultaneously tapered end preferably is provided.
Have in order to reach the above order, the utility model is achieved through the following technical solutions:
A kind of dual safety lock and key comprise: tapered end, lock core, pellet shot from a slingshot, spring, key is characterized in that: be provided with one group of taper pellet shot from a slingshot and magnetic bullet in tapered end at least; On the key, be provided with and corresponding depression of pellet shot from a slingshot and little magnetic sheet with taper pellet shot from a slingshot and magnetic bullet corresponding position.
In the utility model, described lock core can be to have the perforate of sheet mortise lock spoon, and depression and little magnetic sheet are located at the two sides of sheet key respectively.Certainly lock core also can be to have the perforate of cylindric mortise lock spoon, and depression and little magnetic sheet are located at respectively on the outer circumference surface of cylindric key.Depression and little magnetic sheet are located at round outer surface, but depression and little magnetic sheet arranged crosswise.Make that the possibility of key repeated code is lower.
The course of work of the present utility model is as follows: the key that will have depression and little magnetic sheet inserts lock core, and the taper pellet shot from a slingshot in the lock core is pressed into corresponding depression on the key under the effect of spring; Simultaneously, because the effect of little magnetic sheet and magnetic bullet, magnetic bullet all is pressed in the pellet shot from a slingshot hole in the tapered end (or lock core), just can opens tapered end.When the little magnetic sheet on the key or depression are not corresponding with taper pellet shot from a slingshot or magnetic bullet in the tapered end, just can't open tapered end.
Advantage of the present utility model is: the tapered end that taper pellet shot from a slingshot and magnetic bullet mix use is installed, to reach the double anti-theft purpose in tapered end and lock core.Use cylindric key, not only can increase the fastness of key, can also reduce the possibility of the repeated code of key greatly.
Below in conjunction with accompanying drawing, further be elaborated:
Fig. 1 is the utility model embodiment 1 schematic diagram.
Fig. 2 is the utility model embodiment 2 schematic diagrames.
As shown in Figure 1: dual safety lock and key comprise: tapered end 1, lock core 2, spring 3, key 4 are provided with one group of taper pellet shot from a slingshot 5 and magnetic bullet 6 at least in tapered end; On the key, be provided with and corresponding depression 7 of pellet shot from a slingshot and little magnetic sheet 8 with taper pellet shot from a slingshot and magnetic bullet corresponding position.Lock core has the perforate of sheet mortise lock spoon, and depression and little magnetic sheet are located at the two sides of sheet key respectively.
As shown in Figure 2: lock core 2 also can be to have the perforate of cylindric mortise lock spoon, and depression and little magnetic sheet are located at respectively on the outer circumference surface of cylindric key 9.Can reduce the possibility of the repeated code of key greatly.The tapered end that taper pellet shot from a slingshot 5 and magnetic bullet 6 mix use is installed, to reach the double anti-theft purpose in tapered end 1 and lock core 2.
Claims (3)
1, a kind of dual safety lock and key comprise: tapered end, lock core, pellet shot from a slingshot, spring, key is characterized in that: be provided with one group of taper pellet shot from a slingshot and magnetic bullet in tapered end at least; On the key, be provided with and corresponding depression of pellet shot from a slingshot and little magnetic sheet with taper pellet shot from a slingshot and magnetic bullet corresponding position.
