The present invention relates to a button-type panel door opening and closing device, in particular, the protrusion of the button body held on the spring pushes the support jaw of the movable body so that the hook of the movable body is peeled off the hook of the door to open the door, To a panel door opening and closing device which is closed.

In the conventional panel door opening and closing device, as shown in FIG. 2, a pair of hooks 33 protruding from the inner surface of the door 32 held by the panel body 31 are caught by the catching rod 34. When the 32 is pushed, a pair of catching hooks 33 protruding from the inner surface of the door 32 are caught by the catching rod 34. When the door 32 is pushed, the catching hooks protruding from the inner surface of the door 32 ( 33 is caught by the locking rod 34 and closes, and when the door 32 is pulled out, the locking ring 33 is separated from the locking rod 34 to open the door 32, but the hook 33 is repeatedly used. ) Or the engaging rod 34 is worn, so that the opening and closing of the door 32 cannot be performed, and the door 32 is opened and closed by hand.

The present invention is to solve the above problems, the button and the operation movable body, and the door is caught by the hook of the door to go away from each other by pressing the button to open the door automatically, the panel door to improve the reliability of the product As an object of providing an open and close device, it will be described in detail the configuration and operation effects of the present invention with reference to the accompanying drawings.

1a, 1b is a view showing the panel door opening and closing device of the present invention, one end is protruded to the outside of the panel 9, the other end is formed with a projection 11 is provided with a button body 10, A base 8 is formed in contact with the protrusion 11 and one side thereof is extended so that a ring 7 is formed at an end thereof so as to be rotatable inside the panel 9 to interlock with the movement of the button body 10. The movable body 6 installed on the body 4, the locking ring 2 is formed so as to be caught by the ring 7, the door 1 is installed to be rotatable, and the door 1 is opened in the direction in which the door 1 is opened. 1) an elastic member 3 for applying an elastic force to the elastic member 1 and an elastic force for applying the elastic force to the movable body 6 so that the hook 7 of the movable body 6 always engages with the locking ring 2 of the door 1; Member 5, wherein reference numeral 12 is a door support shaft, 13 is a movable support shaft, 14 is a hook of the button body, and 15 is supported by the button body. It is a tension spring.

Referring to the effect of the present invention configured as described above with reference to Figure 1 (a) (b) as follows.

First, as shown in (a) of FIG. 1, when the locking ring 2 is caught in the hook 7 of the movable body 6 and the door 1 is in the closed state, the panel 9 is opened to open the door 1. When the button body 10 protruding from the outside is pressed as shown in FIG. 1B, the protrusion 11 of the button body 10 pushes the supporting jaw 8 of the movable body 6 to move. As the sieve 6 receives the elastic force of the elastic member 5 and rotates clockwise around the shaft 13, the hook 7 of the movable body 6 is raised to catch the door 1. The door 1 is opened in the direction of the arrow by the elasticity of the elastic member 3 accordingly.

When the user releases the button body 10 pressed by the user, the button body 10 and the movable body 5 are moved by the restoring force of the tension spring 15 and the elastic member 5, respectively. Will return to its original state.

On the other hand, when the door 1 is pushed by the hand to close the door 1, the locking projection 2 of the door 1 slides the hook 7 of the movable body 6 so that the hook 7 of the movable body 6 is closed. ) Is raised and lowered slightly upward, so that the locking projection 2 of the door 1 is caught by the hook 7 of the movable body 6 and closed as shown in FIG. The locking projection 2 is subjected to the elasticity of the elastic member (3).

As described above, according to the panel door opening and closing device of the present invention, when the button body is increased only once, the door is opened automatically, thereby improving the quality of the product, and in particular, it is to open and close accurately even for a long time.

Claims (1)

One end protrudes from the outside of the panel 9 and a protrusion 11 is formed at the other end to the button 10 installed to be movable horizontally, and a support jaw 8 is formed to contact the protrusion 11 and one side thereof is extended. And a ring 7 formed at an end thereof, the movable body 6 installed on the body 4 to be rotatable inside the panel 9 to interlock with the movement of the button body 10, and the ring 7. A door 1 having a locking ring 2 formed therein so as to be locked to be rotatable, an elastic member 3 for applying an elastic force to the door 1 in a direction in which the door 1 opens, and the movable body 6 Panel door opening and closing device, characterized in that consisting of an elastic member (5) for applying an elastic force to the movable body (6) so that the ring (7) is always caught with the locking ring (2) of the door (1).
