When the outdoor is used, the key is used to control the lock body for locking and unlocking. The lock set is mounted on a side of the door corresponding to the door. In addition to connecting the lock body to control the expansion and contraction of the lock tongue, the screw type is also used. The corresponding group of connecting elements is arranged in the control lock group to achieve a stable assembly relationship between the door lock and the door panel.

However, the above-mentioned mechanical door locks are complicated in structure and high in cost, so that the electronic lock or the smart inductive door lock and the like provide consumers with other options, so how to provide a door lock with simple structure, low cost and convenient use. , has always been the direction of research for creators.

The main purpose of this creation is to provide a simple structure, low cost and easy to use. The door lock.

For the above purposes, the present invention provides a door lock including an outer lock head, an inner lock head and a lock core portion, wherein the outer lock head is disposed outside a body, and the outer lock head is provided with a a keyhole is inserted into the lock hole, the inner lock head is disposed in a door body, and the inner lock head is provided with a knob for opening the door body, and the lock core portion is disposed on the outer lock head and the inner lock head And the lock core portion is provided with a lock tongue for restricting opening and closing of the door body; wherein the inner lock head is provided with a pivot shaft which can pass through one of the shaft holes of the lock core portion to be engaged therein In the outer lock head, the shaft hole of the lock core portion is connected to the lock tongue, so that when the lock hole of the outer lock head or the knob of the inner lock head is rotated, the pivot shaft can drive the shaft hole to rotate. In turn, the locking tongue is extended or retracted to cause the door body to open or close.

In implementation, the shaft hole of the lock core portion is a cross-shaped shaft hole.

In implementation, the outer lock and the inner lock head each include a panel for locking to the door body.

In order to further understand the present invention, the preferred embodiments of the present invention, together with the drawings and figure numbers, detail the specific components of the present creation and the effects achieved thereby.

FIG. 1 is a schematic exploded view showing the structure of a door lock of the present embodiment.

Figure 2 is a schematic diagram of the combination of the door lock groups of the present embodiment.

Fig. 3 is a schematic view showing the locking of the door body in the present embodiment.

Fig. 4 is a schematic view showing the unlocking of the door body in the present embodiment.

Please refer to FIG. 1-4, which is a specific embodiment of the creative door lock, which is composed of an outer lock head 1, an inner lock head 2 and a lock core portion 3, and is particularly suitable for assembling in a push door or Pull on the door.

The outer lock head 1 is disposed outside a door body 4, and the outer lock head 1 is provided with a keyhole 11 for key insertion.

The inner lock head 2 is disposed in a door body 4, and the inner lock head 2 is provided with a knob 21 for opening the door body 4.

The lock core portion 3 is disposed between the outer lock head 1 and the inner lock head 2, and the lock core portion 3 is provided with a lock tongue 31 that can restrict the opening and closing of the door body 4.

The inner lock head 2 is provided with a pivot 22 which can pass through one of the shaft holes 32 of the lock core portion 3 to be engaged in the outer lock head 1. The shaft hole 32 of the lock core portion 3 is It is a cross-shaped shaft hole 32, and the shaft hole 32 of the lock core portion 3 is connected to the bolt 31. Moreover, the outer lock head 1 and the inner lock head 2 each include a panel 12, 23 for locking to the door body 4.

In the implementation, when the user wants to open or lock the door body 4 outdoors or indoors, when the keyhole 11 of the outer lock head 1 is twisted by the key insertion, or the knob 21 of the inner lock head 2 is When the hand is rotated, the pivot 22 can drive the shaft hole 32 to rotate, thereby interlocking or retracting the bolt 31 to cause the door body 4 to open or close.

Therefore, through the interlocking design of the outer lock head 1, the lock core portion 3 and the inner lock head 2, the purpose of opening or locking can be achieved, and the utility model has the advantages of simple structure, low cost and convenient use.

The foregoing is a specific embodiment of the present invention and the technical means employed, and many variations and modifications can be derived therefrom based on the disclosure or teachings herein, and can still be regarded as equivalent changes made by the inventive concept. The role of the spirit and the spirit of the text and the scope of the text should be considered within the technical scope of this creation.
