Conventional door key devices include mechanical key devices and electronic key devices. The mechanical key device is a device for opening and closing a door by mechanical matching of a door key device having a mechanical structure corresponding to the corresponding door key. On the other hand, the electronic key device is a device for opening and closing the door by an electronic signal or password input from the outside.

Recently, as one of the electronic key devices, a key device using electronic information has been put into practical use. The key device using the electronic information does not use a general mechanical key, but checks the electronic information key having the EEPROM (Electrically Erasable Programmable Read-Only Memory) in which the ID code is stored and the ID code of the electronic information key. A door key device having a key reading device for authenticating a key. Key information using electronic information has the advantage of easy door key operation and prevents damage due to unauthorized copying, unlike mechanical keys.

On the other hand, mechanical keys or keys using electronic information are at risk of loss. Therefore, by using either a mechanical key or a key using electronic information and a digital keypad in which 10 numeric keys and "*" and "#" keys are arranged together, a key using a mechanical key or electronic information is used. In the event of a loss, a dual key device that allows a user to open or close the door by entering a password on a digital keypad has recently become commonplace.

The configuration of a general door lock in this case is as shown in FIG.

1 is a perspective view of a conventional digital door lock using a slide method.

The door lock 100 using a slide method includes a main body 110 and a main body 110 including a key receiving unit 140, a lever 150, and a digital keypad 130 that accommodate a mechanical key or a key using electronic information. It includes a slide cover 120 that can be slide (Slide) on the top.

In general, the key receiving unit 140 is directly exposed to the outside and the digital keypad 130 is generally covered with a slide cover 120 having a slideable structure. Thus, sliding the slide cover 120 upwards exposes the digital keypad 130 for entering a password.

The door lock 100 is typically set the limit of the vertical operation of the slide cover 120, the leaf spring 120 is made of a leaf spring (Spring) to prevent the slide cover 120 from being excessively slid away from the main body A stopper 200 is provided.

Figure 2a is a cross-sectional view for explaining the operating state of the leaf spring stopper when the slide cover is closed in the conventional door lock using a slide method, Figure 2b is to explain the operating state of the leaf spring stopper when the slide cover is opened It is a section for.

The leaf spring stopper 200 is fixed to the main body 110 by a fixing screw 220. At this time, the plate spring stopper 200 is fixed to the main body 110 and the surface supporting the slide cover 120 in order to have elasticity, so that the main body 110 is generally a plate spring stopper ( A stopper receiver 210 is formed to form a groove similar to a leaf spring shape for accommodating 200. The leaf spring stopper 200 is formed by bending a thin plate to have elasticity, and a protrusion 202 is provided at a portion in contact with the slide cover 120.

As shown in FIG. 2A, when the slide cover 120 is closed, the protrusion 202 of the leaf spring stopper 200 is caught by the first locking step 230 provided in the slide cover 120. Accordingly, when the slide cover 120 is closed, the protrusion 202 of the leaf spring stopper 200 is caught by the first catching jaw 230, and the user feels that the slide cover 120 is completely closed.

On the other hand, when the slide cover 120 is opened as shown in Figure 2b, the second latching jaw 240 is provided at the limit point that the slide cover 120 is raised to the maximum. Therefore, when the slide cover 120 is opened as much as possible, the protrusion 202 of the leaf spring stopper 200 is caught by the second locking jaw 240, and the user feels that the slide cover 120 is fully opened. In addition, the separation prevention jaw 250 protrudes from the bottom of the second locking jaw 240. The release prevention jaw 250 has the end of the protrusion 202 of the leaf spring stopper 200 is caught so that the slide cover 120 is no longer up, the slide cover 120 is not separated from the main body 110 Will not.

Also, although not shown in FIGS. 2A and 2B, the protrusion 202 of the leaf spring stopper 200 facilitates the slide cover 120 between the first catching jaw 230 and the second catching jaw 240. It is common for the guide part to which the protrusion part 202 slides so that it may be hardened.

Thus, the leaf spring stopper 200 sets the limit point of the up and down operation of the slide cover 120 and prevents the slide cover 120 from being separated, and also has a constant elasticity when the slide cover 120 is operated up and down. It will also play a role.

However, the conventional leaf spring stopper 200 has the following problems.

Conventional stoppers using leaf springs are typically made of steel, such as stainless steel, in order to maintain proper elasticity, the thickness of the plate constituting the leaf spring should not be too thick. By the way, when the thickness of the plate constituting the leaf spring is thin when using the leaf spring stopper 200 for a long time there is a problem that the elasticity of the stopper is weakened.

When the elasticity of the stopper is weakened, the slide cover cannot be supported with sufficient force, resulting in poor operation feeling when the slide cover is opened and closed. In addition, when the elasticity of the leaf spring stopper is remarkably dropped, the function of holding the slide cover is reduced, so that the slide cover is separated upward when the slide cover is opened.

In order to solve the above problems, the present invention, the latch plate and the latch plate is connected to the fixing plate fixed to the main body of the door lock and the fixing plate and the hinge to set the opening and closing threshold of the slide cover and prevent the slide cover from falling off It is an object of the present invention to provide a latch-type stopper made of a spring and a door lock including the same.
