Description

Fixing means for door locks

The present invention relates to a fixing means for a door lock, and more particularly, to a fixing means for a door lock, in which a fixed elastic body bent a plurality of times to the rear of the outer door body such that the outer door body is naturally fixed after the first- To a door lock fixing means formed.

Generally, a door lock is a device for unlocking a locked door and re-locking the opened door, and is widely used as a door opening / closing device for doorways of general houses or doors of apartments, businesses, offices, It is divided into mechanical door lock and digital door lock.

In the conventional door lock, which is widely used as a general form of door lock, a user manually operates a key bundle by a key to release the locking device, and then operates a knob connected to the door lock to open and close the door.

On the other hand, if a user inputs information for key authentication using a key pad, an electronic information key, a biometric information key, or the like, the digital door lock may be a solenoid or a motor The door is opened and closed by operating the motor to release the locking device and operating the handle connected to the door lock.

On the other hand, the mechanical door lock has a problem that the metal key used as the authentication means is vulnerable to loss and duplication, and thus the security is poor.

Recently, in order to solve the security weakness of conventional mechanical door locks, the use of digital door locks with improved user convenience and security has been increasing.

As shown in FIG. 1, the conventional door lock includes an external body 100 having a key or authentication means, and an internal plate 200 connecting the internal body for manually operating the key or authentication means from the inside. In order to install the outer body 100 and the inner plate 200 of the inner body on a specific portion of the door, a predetermined portion of the door is first drilled, and then the outer body 100 and the inner plate 200 It is common to connect them by connecting them.

However, in the conventional installation work for the door lock, the external body is gripped from one side of the door and the interior body is gripped from the other side of the door, and then the fixing operation is performed. Has to use both hands, so that the work itself is very inconvenient and the working time is unnecessarily long.

In order to solve the above problems, Korean Patent No. 10-1391234 has been disclosed. FIG. 1 is a perspective view showing a conventional door lock fixing device.

However, the conventional door lock fixing device is elastically connected to the inner plate 200 provided inside through the fixing device 300 including the coupling cover 301, the coupling screw 302 and the spring 303, The door lock of the inner plate 200 can be conveniently fixed to the door, but the process of connecting the fixing device 300 to the inner plate 200 does not solve the problem that the operator must use both hands.

Further, in the conventional door lock fixing device, a plurality of coil springs and a coupling screw are provided to add the elastic action of the coupling cover 301, and the structure is complicated, resulting in an increase in manufacturing cost.

The present invention has been made to solve the above problems of the prior art, and it is an object of the present invention to provide a fixing device for a vehicle, which comprises a fixed elastic body bent a number of times at the rear of an outer door body when fixing the outer door body to a back mount panel, It is provided with a pressure washer which is elastically moved when the main body is firstly inserted and is elastically moved when the back mount panel and the connecting bolt are fastened, so that the connecting bolt is easily fastened to the back mount panel, There is provided a bolt restricting cover whose one side is opened on the rear surface so that the bolt head is prevented from being overturned to the rear side, so that untrained workers can be easily installed and the manufacturing cost of the door lock is reduced .

In order to achieve the above object, the door lock fixing means according to the present invention includes an outer door main body installed on a front surface of a door, and a door lock panel including a back mount panel provided on a rear surface of the door for fixing the outer door main body. A fixing means body protruding as a fixing means in a rear direction of the outer door body and a connecting bolt connected to the back mount panel on a rear surface of the fixing means body; A plurality of elastic seat receiving grooves formed in the axial direction of the fixing means body are formed on the outer circumferential surface of the fixing means body, and the elastic seat receiving grooves are provided with a plurality of fixing portions, which are bent in one direction so as to be fixed without being shaken when the fixing means body is inserted into the mounting holes of the door And an elastic body is formed.

And the fixed elastic body is composed of a fixing part raised upward and an elastic part bent downward.

The connecting bolt includes a connecting bolt body connected to a rear end surface of the fixing means body and having a bolt head formed at one end thereof, a coil spring inserted into the outer circumferential surface of the connecting bolt body and contacting the rear surface of the fixing means body, And a pressing washer provided between the spring and the head of the bolt.

The back mount panel has insertion holes into which the bolt heads are inserted at both sides so that the connection bolt bodies are inserted and fixed after the insertion of the connection bolt bodies, and connecting slit holes connecting the respective insertion holes and having a diameter smaller than the diameter of the bolt heads.

And a bolt limiting cover is formed on the rear surface of the insertion hole so as to cover the periphery of the insertion hole and open at one side thereof, so that the connection bolt main body is prevented from being moved backward when the main body is inserted.

Thus, the door lock fixing means according to the present invention has the following effects.

First, when the door lock main body, that is, the outer door main body is inserted into the outside of the door and fixed to the back mount panel, the fixing elastic body is bent many times in the fixing means body provided at the rear of the outer door main body, The operator is able to perform the fastening operation very conveniently because the operator does not need to use both hands when fixing it by the action of the fixed elastic body,

Secondly, when the back mount panel and the connecting bolt are fastened, a coil spring for elastically acting the pressing washer and the pressing washer provided between the bolt heads of the connecting bolt is provided, thereby moving the back mount panel up and down, Can be conveniently fastened,

Thirdly, since the bolt-limiting cover is formed on the rear surface of the insertion hole into which the bolt head is inserted to cover the circumference of the insertion hole and one side is opened, when the connection bolt body is inserted into the insertion hole, The fastening operation can be smoothly advanced.
