Description

Turning an axis length control easy door lock equipment}

The present invention is organically connected to the lock bunch and the door handle indoors or the outdoor key bundle when the door lock device is installed on the door to lock the door is turned into the door handle or key bundle to turn the key The door lock can be adjusted freely according to the thickness of the door to install the shaft that is necessary to open and close the door by intercepting the locker provided in the lock bundle while rotating by force. The door lock device is free to adjust the length of the rotation shaft in accordance with the thickness of the door to facilitate the installation of.

In general, door locks that can lock the doors are installed at the doors of various buildings, especially entrance doors that can enter the room as a minimum device for protecting personal safety as well as personal safety from others. Currently, the door lock devices installed are not only mechanical, but also electric and electronic products that are pinched or unlocked by manipulating cards or buttons, and even a variety of products such as fingerprints, voices, eyeballs, etc. It is used.

DOOR LOOK devices of these various products are not completely electronic, that is, if they are mechanically included, such as all mechanical or mixed type of electric, electronic, and mechanical combination, must be installed in the lock bunch and indoors When the key is inserted into the door handle or the key bundle, it is rotated by its force, and the pivot shaft which interrupts the opening and closing of the door by inverting the door lock need.

In the case of such a pivot, the length must be varied depending on the thickness of the door.

Therefore, in the related art, by forming a plurality of cutting notches at regular intervals on the rotation shaft, when the door is thin and the length of the rotation shaft is long, the cutting notch portion is cut to have an appropriate length, and thus the length of the rotation shaft is shortened.

However, in order to cut the end of the rotation shaft, it was very inconvenient and there was a risk of safety accident because it had to be cut off with a separate hacksaw or pullout. There are many cases where the notched part is cracked or cut and can not be used, which is more dangerous when the part to be cut is not the cut notch but the cut notch and the cut notch.

In addition, it is not easy to accurately measure the length required to cut the remaining part by leaving only the length of the rotating shaft to be used. If the rotating shaft is cut to a long length, it is inconvenient to cut it again. If you cut the length too short from the beginning, you will not be able to rotate the shaft at all.

In some door locks, the rotation shaft is already combined with the key bundle itself into which the key is inserted, so in this case, the economic damage is often caused because the key bundle itself needs to be replaced with a cylinder.

The present invention has been made in order to solve the above-mentioned conventional problems, the one side of the rotating shaft coupled to the organic side door knob or the outdoor side of the key when the installation of various door lock devices are coupled to each other is coupled Particularly, the cutting shaft is formed in the shaft coupling hole of the pivot shaft engaging portion formed at the front end of the indoor door handle, and the tip of the spring is coupled to the shaft coupling hole so that the tip of the pivot shaft is coupled with the outdoor key bundle. Since the tip of the rotation shaft is inserted thinly or deeply while receiving the spring force in the shaft coupling hole according to the thickness of the door, the length of the rotation shaft is naturally adjusted, so there is no need to cut the rotation shaft according to the thickness of the door. As a result, the purpose of the door lock is very easy to install regardless of the thickness of the door.

When explaining the present invention for achieving the above object by one embodiment shown in Figures 1 to 2 as follows.

The lock bundle 100 and the door handle 210 of the indoor main body 200 or the key bundle 340 of the outdoor main body 300 are organically connected to each other by the rotation shaft 400 to turn the door handle 210. When the key is inserted into the key bundle 340, the rotation shaft 400 rotates by the force thereof, and the lock latch 110 provided in the lock bundle 100 is spouted to open and close the door 1 to the door lock device configured to control the opening and closing of the door 1. In

The cutting groove 222 is formed in the shaft coupling hole 221 of the rotation shaft coupling portion 220 formed at the tip of the door handle 210 of the indoor main body 200, in particular, at which one end of the rotation shaft 400 is coupled. Forming and engaging the front end (230a) of the spring 230 in the incision groove 222, the outer side of the ball 340 and one side of the rotating shaft 400 is coupled to the shaft coupling hole 221 When the other end is combined, the tip of the pivot shaft 400 is inserted into the shaft coupling hole 221 thinly or deeply while receiving the elastic force of the spring 230 according to the thickness of the door 1, and thus the length of the pivot shaft 400 is naturally. Is made to be adjusted.

Here, the rotation shaft 400 is a unitary body.

As described above, the present invention is not limited to the above embodiment, and the shape of the rotation shaft 400 and the connection state of the rotation shaft 400 and other devices may be variously modified.

When the door lock device of the present invention configured as described above is fixed to the door (1) and described in detail the coupling state of the rotating shaft 400 according to the thickness of the door (1).

First, the lock bundle 100 having the locking latch 110 and the locking latch 120 formed in the state in which the outdoor main body 300 is firmly fixed to the outer wall surface 1a of the door 1 by the body fixing device 15 is formed. Coupling after inserting the tip of the rotating shaft 400, the pin groove 410 is formed in the shaft insertion hole (140a) provided in the rotating hole 140 of the lock bunch 100 (key bundle formed in the outdoor main body 300 ( The rotation shaft coupling pin 341 of the 340 is caught by the pin groove 410 at the tip of the rotation shaft 400.

In this way, the rotation shaft 400 is configured separately and coupled after installation of the lock bunch 100, so that the lock bunch 100 can be easily installed on the pivot shaft 400 as in the related art.

In such a state, in order to couple the indoor main body 200, first of the rotation shaft 400 in which the pin groove 410 of the tip is hung on the rotation shaft coupling pin 341 of the key bundle 340 of the outdoor main body 300. The other end is inserted into the shaft coupling hole 221 of the rotation shaft coupling portion 220 formed at the front end of the door handle 210 of the indoor main body 200.

As described above, the shaft coupling hole 221 has a cutting groove 222 formed therein, and the cutting groove 222 has a tip end of the spring 230 installed on the outer shaft coupling part 220 at the outer side thereof. Rotating shaft 400 coupled to the coupling hole 221 is elastically installed to receive the elastic force of the spring 230.

Therefore, even though the tip of the rotational shaft 400 is not fixed to the rotational shaft coupling pin 341 and is configured separately, the rotational shaft 400 is in a state of continuously receiving the elastic force of the spring 230. Regardless of whether the length of the rotary shaft 400 is short or long, there is no fear that the pin groove 410 formed at the tip of the rotary shaft 400 escapes from the pivot shaft coupling pin 341 of the key bundle 340.

Thus, the present invention, when the thickness of the door (1) is thick as shown in Figure 3a attached to the rotating shaft 400, the rotating shaft coupling portion 220 formed at the front end of the door handle 210 of the indoor main body 200 side It is inserted into the shaft coupling hole 221 of a little, on the contrary, if the thickness of the door 1 is thin as shown in Figure 3b attached to the rotating shaft 400 is inserted deeply into the shaft coupling hole 221 Since the length of the coaxial 400 is automatically adjusted, the installation is easy regardless of the thickness of the door 1, as well as the other end of the rotation shaft 400 by the spring 230 is installed in the shaft coupling hole 221 Since the elastic force is continuously received, the pin groove 410 formed at the tip of the rotation shaft 400 does not have to worry about escaping from the rotation shaft coupling pin 341 of the key bundle 340, and thus operation is more perfect than any door lock device.

In the present invention as described above, the door handle formed on the indoor main body or the front end of the rotating shaft coupled to the key bundle formed on the outdoor main body to be organically connected to each other when the door lock device is installed, in particular, the indoor main body side door handle tip Since the cutting groove is formed in the shaft coupling hole of the rotation shaft coupling portion formed in the coupling shaft and the tip of the spring is coupled to the shaft groove, the other end of the rotation shaft is coupled to the key assembly of the outdoor main body side of the shaft coupling hole. Depending on the thickness of the door, the end of the rotation shaft is inserted thinly or deeply while receiving the elastic force of the spring in the shaft coupling hole so that the length of the rotation shaft is naturally adjusted, and the other end of the rotation shaft is connected to the spring installed in the shaft coupling hole. There is no fear that the pin groove formed at the tip of the rotation shaft will escape from the pins of the key bundle by continuously receiving the elastic force. So as to not have a need to be cut to the rotation shaft in accordance with the thickness of the door such that the rotation shaft so as to facilitate the operation is very epoch-making invention that has effects such as the installation is very easy for the door lock, regardless of the thickness of the door.
