Abstract

The utility model discloses a key and a lock core which are convenient to be used. The key comprises a key body which is a cylinder; the end surface of the key body takes the shape of a cone; the end surface of the key body is provided with two symmetrical grooves; the key body is provided with concave spots with different depths; the lock core matched with the key comprises a lock core body which is provided with a cylindrical bore; the side part of the bore of the lock core body is provided with a stepped through hole vertical to the bore; inner lock pins with different lengths are sequentially installed in the stepped through hole; the side part of the bore of the lock core body is provided with the stepped through hole corresponding to the groove of the head of the key; a rotating blocking pin is installed in the stepped through hole; and the top of the lock core body is provided with a convex slot. As the key body of the key is the cylinder, directivity does not exist when the key is inserted for unlocking a lock. Therefore, the key and the lock core have extremely convenient use, and are more convenient for the old and the children to use in dark environment.

Description

Key and lock core

Technical field

The utility model relates to a kind of key and lock core.

Background technology

Common key is when opening lock, and because of having directionality, key must be aimed at the relevant position of fore shaft, could insert unlatching, and the key turns amplitude is bigger when opening lock, therefore exists to open the shortcoming that is difficult for.

Summary of the invention

Technical problem to be solved in the utility model provides a kind of key easy to use and lock core.

For solving the problems of the technologies described above, the utility model by the following technical solutions: a kind of key comprises a spoon body, described spoon body is a cylinder, the end face of spoon body becomes coniform, is shaped on the groove of two symmetries at the end face of spoon body, is shaped on the concave point of the different depths on the spoon body.

The lock core that a kind of and above-mentioned key matches, comprise lock core body, described lock core body is provided with cylindrical bore, endoporus sidepiece at lock core body is shaped on the step through-hole perpendicular with endoporus, pack into successively in the step through-hole interior lock pin of different length, be shaped on and the relative step through-hole of groove of spoon body head at the endoporus sidepiece of lock core body, this step through-hole rotation bayonet lock of packing into is shaped on tongue at the top of lock core body.

The beneficial effects of the utility model are: because the spoon body of key is a cylinder, when inserting key operated lock, do not have directionality, therefore extremely easy to use, especially under the environment of dark, old man and children use more convenient.

The utility model will be further described below in conjunction with the drawings and specific embodiments.

Fig. 2 is the plan structure schematic diagram of key among Fig. 1;

Fig. 3 is the general structure schematic diagram of a kind of embodiment of the utility model lock core;

Fig. 4 is the A-A sectional view among Fig. 3.

The specific embodiment

As shown in Figure 1 and Figure 2, a kind of embodiment of the utility model key comprises spoon body 1, and described spoon body 1 be a cylinder, and the end face of spoon body 1 becomes coniform, is shaped on the groove of two symmetries at the end face of spoon body 1, is shaped on the concave point of the different depths on spoon body 1.

As shown in Figure 3, Figure 4, a kind of embodiment of the utility model lock core, comprise lock core body 2, described lock core body 2 is provided with cylindrical bore, endoporus sidepiece at lock core body 2 is shaped on the step through-hole perpendicular with endoporus, and the interior lock pin of the different length of packing into successively in the step through-hole is shaped on and the relative step through-hole of groove of spoon body 1 head at the endoporus sidepiece of lock core body 2, this step through-hole rotation bayonet lock of packing into is shaped on tongue at the top of lock core body 2.

The operating principle of the utility model key and lock core is: as Fig. 2, shown in Figure 4, when opening lock, when spoon body 1 inserts lock core body 2, when rotation spoon body 1 arrives the relevant position, the rotation bayonet lock that lock core body 2 is provided with is under the effect of rotating the bayonet lock spring, snap in the groove of spoon body 1, concave point pushing tow interior lock pin, outer lock pin and spring separately on the spoon body 1, the top of the interior lock pin of different length is aligned, this moment can rotation lock core body 2, the groove that is driven on the dead bolt 8 by the tongue on the lock core body 2 rotates, and reaches the action that undoes the lock.

Claims

1. a key comprises a spoon body, it is characterized in that: described spoon body is a cylinder, and the end face of spoon body becomes coniform, is shaped on the groove of two symmetries at the end face of spoon body, is shaped on the concave point of the different depths on the spoon body.

2. lock core, comprise lock core body, it is characterized in that: described lock core body is provided with cylindrical bore, endoporus sidepiece at lock core body is shaped on the step through-hole perpendicular with endoporus, pack into successively in the step through-hole interior lock pin of different length, be shaped on and the relative step through-hole of groove of spoon body head at the endoporus sidepiece of lock core body, this step through-hole rotation bayonet lock of packing into is shaped on tongue at the top of lock core body.
