The conventional rotatable sliding device illustrated in FIG. 8 includes a main body 110, a movable body 120 slidably coupled in a longitudinal direction of the main body, and a rotating body 130 rotatably coupled to the movable body 120. It is composed. The rotating body 130 is configured to adjust the rotational force by the leaf spring 170 installed between the fixed plate 160 and the rotating plate 150.

In addition, although not shown, an elastic member used for a slider for a known semi-automatic mobile phone is installed between the main body 110 and the movable body 120. As the elastic member, a pair of torsion springs, a pogo pin with a built-in spring, and the like are used. In addition, a link slider using a tension spring of the type disclosed in Korean Utility Model Publication No. 20-376773 filed by the inventor of the present invention is also used.

As shown in Figure 8, the rotary hinge used in the conventional mobile phone has a drawback that the thickness is thick because the elastic member for adjusting the rotational force for rotating the rotating plate is installed between the fixed plate and the rotating plate.

In addition, the slider used in the conventional mobile phone has a problem that the spring is excessively deformed while the slider moves up / down position, so that the spring is broken by fatigue or the elastic restoring force is weakened when used for a long time.

When manufacturing a composite slider capable of sliding and rotational movement using a conventional rotary hinge or a slider, there is a problem that the thickness of the mobile phone is thick and the spring is damaged by fatigue or the restoring force is weak.

The object of the present invention is to provide a slim slider for a mobile phone that can be slid and rotated by using a rotary hinge and a slider having a structure that can be made thin. An object of the present invention is achieved by forming a locking groove in the inner circumferential surface of the through hole formed in the fixed plate or the rotating plate, and the pressing member in contact with the inner circumferential surface is inserted into the locking groove after a predetermined angle rotation. In addition, a slider having a link provided to minimize the deformation of the spring is provided to increase the durability of the slider.

And a sliding plate which is guided to the guide of the rotating plate and is slidably installed and fixed to the cover of the mobile phone in which the display device is installed. The fixing plate is formed with a circular through hole, and a plurality of engaging grooves are formed along the longitudinal direction of the through hole at regular intervals on the inner circumferential surface of the through hole. In addition, the composite slider assembly according to the present invention is a hoop shape having an outer diameter smaller than the inner diameter of the through hole of the fixing plate, at least one locking projection is formed on the outer peripheral surface to be inserted into the plurality of locking grooves, the at least one The guide protrusion is formed by protruding from the front of the outer peripheral surface formed around the outer peripheral surface of the flexible projection, inserted into the through hole of the fixing plate and is installed to be rotatable, and inserted into the flexible hoop rotor and fixed close to the inner peripheral surface Ring springs. The rotating plate is formed with a through hole, a long hole is formed in a radial direction around the through hole, and the guide hoop of the flexible hoop rotor is mounted on the front of the flexible hoop rotor to be inserted into the long hole. have.

According to the present invention, when the rotating plate is rotated, the guide hoop of the flexible hoop rotor is inserted into the long hole of the rotating plate so that the flexible hoop rotor is also rotated together. When the flexible hoop rotor rotates, the locking protrusion formed on the outer circumferential surface is released from the locking groove of the fixing plate and pressed by the inner circumferential surface of the fixing plate, so that the portion of the flexible hoop rotor on which the locking protrusion is formed is equal to the height of the protrusion of the locking protrusion. The inner side of the through hole is deformed. At this time, the ring spring fixed in close contact with the inner circumferential surface of the flexible hoop rotor is deformed to uniformly press the inner circumferential surface of the flexible hoop rotor in a radial direction by restoring force. Thus, the outer circumferential surface of the flexible hoop rotor rotates while being in close contact with the inner circumferential surface of the through hole of the fixed plate. Friction occurs when the outer circumferential surface of the flexible hoop rotor and the inner circumferential surface of the fixed plate through-hole slide, and a rotation force greater than the friction force must be applied to rotate the rotating plate. Therefore, it is possible to prevent the rotating plate is rotated when a rotational force of a predetermined size or less is applied to the rotating plate by chance. In addition, the flexible hoop rotor is adapted to be inserted into the through hole of the fixed plate, so that the thickness of the composite slider assembly can be reduced. Therefore, it is possible to manufacture a compact mobile phone capable of sliding and rotational movement.
