To this end, the guide shaft 121 is fixed to the second plate 120, and guide holes 111 are formed at both side ends of the first plate 110 to slidably couple the guide shaft 121.

The guide shaft 121 is inserted through both ends of the second plate 120, and a plurality of nuts 122 are fixed to both ends of the second plate 120 to prevent the guide shaft 121 from being separated. do.

The guide ball 111 may be completely penetrated at one end of the second plate 120 and partially penetrated at the other end of the second plate 120. At this time, the guide shaft 121 is inserted through one end of the second plate 120, and is supported by passing through the other end of the second plate 120 1/2, one end of the second plate 120 through Is finished with bonding.

The first plate 110 and the second plate 120 are provided with a first through hole 112 and a second through hole 123 at arbitrary points, respectively, and may be made of a synthetic resin material such as plastic.

The first block 130 has a rectangular parallelepiped shape, the inside of which is empty and one surface is completely open, and opposite ends of the open one surface are partially open. Both ends of the partially open first block 130 may form an inclined surface at a predetermined angle. The same third through hole 131 is formed at the center of the other opposing surfaces of the first block 130.

The first joint pin 140 is inserted through the third through hole 131 to rotatably fix the first block 130 to the first plate 110.

The link member 150 is a U-shaped thin rod member, which is inserted from the fully open portion of the first block 130 toward the partially opened both ends of the first block 130, thereby forming the first joint pin 140. It is fixed to the first plate 110 rotatably by).

Compression spring 160 is paired as a coil spring having a diameter corresponding to the thickness of link member 150 and inserted to include the rod portion of link member 150 through the open end of link member 150. do. The compression spring 160 is compressed and tensioned while the link member 150 is inserted therein. The link member 150 and the compression spring 160 may be modularized in a coupled state, and even if an impact is applied to the link member 150 due to the modularization, the link member 150 is less deformed, and its durability is high, thus disassembling well. It doesn't work.

Like the first block 130, the second block 170 is empty, and one surface is completely open, and both ends of the second block 170 are partially open. Both ends of the partially open second block 170 may form a predetermined inclined surface. On the other opposing surface of the second block 170, the same fourth through hole 171 is formed in the center portion, respectively.

The second joint pin 180 is inserted past the fourth through hole 170 to rotatably fix the second block 170 to the second plate 120.

The closed end of the link member 150 is inserted from the partially open end of the second block 170 so that the second block 170 does not leave the link member 150 in the longitudinal direction of the link member 150. You can move. Therefore, since the moving distance between the second block 170 and the compression spring 160 is limited by the sealed end of the link member 150, it is possible to perform the stop function without a separate stopper.

3 to 5 show a closed state, a partially open state and a fully open state of the switchgear according to FIG. 1, respectively.

With reference to Figures 3 to 5 will be described the operation of the opening and closing device according to a preferred embodiment of the present invention.

Since the first plate 110 is attached to the upper front of the first body 101 of the terminal, the second plate 120 is attached over the entire rear surface of the second body 102, the second body 102 of the terminal As shown in FIG. 3, the first body 110 is positioned above the second plate 120, and the second body 102 in which the LCD screen is installed. Is overlapped with the first body 101.

At this time, since the closed end 151 of the link member 150 is located at the center of the second plate 120, and the open end 152 is fixed on the second plate 120, the compression spring 160 The second block 170 is pushed by the elastic force of the second plate 120 to maintain the closed state.

The moving distance between the second block 170 and the compression spring 160 is limited by the closed end 151 of the link member 150, and thus, the second block 170 and the compression spring 160 without a separate stopper are limited. It is possible to stop the movement of.

In this state, when the second body 102 is pushed by hand to open the terminal, the second body 102 and the second plate 120 are lifted together by sliding. At this time, since the guide shaft 121 disposed at both ends of the second plate 120 is coupled to the guide holes 111 formed at both ends of the first plate 110, the second plate 120 is placed on the first plate 110. Good linear motion can be made.

When the second plate 120 starts to open, the second plate 120 pushes the second block 170 rotatably fixed to the second plate 120, and the second block 170 is pushed. The linear movement by the link member 150 in a state coupled to the link member 150 is moved, the distance between the first block 130 and the second block 170 is close. Accordingly, as the compression spring 160 is compressed by the second block 170 moved inwardly of the link member 150 on the link member 150, the second plate 120 and the second body are increased. It acts as a force to prevent 102 from opening.

When the second plate 120 overcomes the disturbing force and continues to move and partially opens as shown in FIG. 4 to cross the inflection point of the compression spring 160, the compression spring 160 moves in the upward direction of the second plate 120. The elasticity of) acts on the second block 170 so that the second plate 120 is automatically raised to a position where the second plate 120 is automatically opened even when no force is applied to the second body 102 and the second plate 120.

At this time, if the second block 170 is accurately positioned at the inflection point, and no force is applied in any of the up and down directions of the second plate 170, the second plate 120 may be formed of the compression spring 160. It stops without moving to up and down by the elastic force. Therefore, the second plate 120 can be stopped on the first plate 110 without a separate stopper.

The distance from the closed position to the inflection point of the second plate 120 is preferably shorter than the distance from the inflection point to the open position, and even if a smaller force is applied by the distance difference, the second plate 120 is closed to the inflection point. The movement of the second plate 120 and the second body 102 may be facilitated by moving.

Once the second body 102 is fully open as shown in FIG. 5, the second plate 120 is kept open by the pushing force of the second block 170 which is subjected to the elastic force of the compression spring 160. At this time, the movement distance of the second block 170 and the compression spring 160 is limited by the closed end of the link member 150, and thus the second block 170 and the compression spring 160 without a separate stopper. ) Movement can be stopped.

When the second body 102 is opened, the keypad mounted on the first body 101 is exposed, so that the user can use the unique function of the terminal.

On the other hand, to close the terminal while the second body 102 is open, the user pushes the second body 102 in the opposite direction as in the open operation by hand. The closing operation of the second body 102 is performed in the reverse order of the opening operation. In this case, after the force is applied by the user from the open position of the second plate 120 to the inflection point, the second plate 120 may be automatically closed by the elastic force of the compression spring 160 after the inflection point. Will be.

When the second body 102 reaches the closed position, the second plate 120 may continue to be closed by the pushing force of the second block 170 under the elastic force of the compression spring 160. .

As such, the sliding opening and closing device of the portable terminal according to the preferred embodiment of the present invention described above is simple to assemble due to the modularization of the link member and the compression spring, and is easy to assemble and separate due to the shape of the integrated link member. It is possible to limit the moving distance between the compression spring and the second block without a stopper, and even if the link member is deformed by an external force, it is not disassembled due to the modularity, thereby improving durability.

The sliding opening and closing device of the portable terminal according to the preferred embodiment of the present invention described above also uses a compression spring having a stronger elastic force than the torsion spring, and by efficiently transmitting the elastic force to the second plate, opening and closing of the second body The operation is smooth and there is an effect that the closed state and the open state are firmly maintained.
