The illustrated figure is an exploded perspective view of the left side of the hinge body 21, the same components are provided symmetrically on the right side of the hinge body 21.

In detail, the hinge body 21 includes an insert sleeve 212 extending in parallel with the stand 12 and a housing 211 formed in a direction crossing the upper end of the insert sleeve 212. In addition, a pair of locking protrusions 214 are symmetrically formed on the outer circumferential surface of the lower end of the insert sleeve 212. In addition, an elastic member accommodating hole 213 for inserting the elastic member 22 is formed in the housing 211. The elastic member 22 is formed with a locking end 221 that is rolled into a cylindrical shape and bent at an end portion. A groove into which the locking end 221 is fitted is formed at an edge of the elastic member accommodation hole 213 formed in the housing 211. That is, the cross section of the elastic member accommodating hole 213 and the cross section of the elastic member 22 are the same, but the diameter of the elastic member accommodating hole 213 is slightly larger than the diameter of the elastic member 22. Can be.

In addition, the shaft 27 rotates while being inserted into the elastic member 22. The diameter of the shaft 27 is slightly larger than the inner diameter of the elastic member 22, so that the elastic member 22 is opened when the shaft 27 rotates. Then, as the display set 13 is tilted, a restoring force is accumulated on the elastic member 22, and the outer circumference of the shaft 27 is strongly adhered to the inner circumferential surface of the elastic member 22. Thus, the display set 13 is prevented from being leaned forward or turned over by its own weight in the tilted state.

The angle adjusting member may include a stopper guide 23 seated at an end of the housing 211, and a stopper 25 seated on the stopper guide 23 to rotate together with the shaft.

In detail, the stopper guide 23 is fixed to the end of the housing 211 by a fastening member. The outer diameter of the stopper guide 23 may be substantially the same as the outer diameter of the housing 211. In addition, a circular hole for penetrating the shaft 27 is formed at the center of the stopper guide 23, and the hole may be formed larger than the outer diameter of the shaft 27. A guide hole 231 is formed between the hole and the edge of the stopper guide 23. The stepped portion 232 may be formed at a point on the inner circumferential surface of the guide hole 231 to stop the tilting of the display set at a specific angle. In addition, a plurality of stepped portions 232 may be formed.

In addition, a through hole 252 through which the shaft 27 penetrates is formed at the center of the stopper 25. A portion of the outer circumferential surface of the shaft 27 is chamfered in the longitudinal direction of the shaft 27, so that the cross section of the shaft 27 is substantially elliptical. In addition, the through hole 252 has the same shape as the cross-sectional shape of the shaft 27. Therefore, when the shaft 27 is fitted to the stopper 25, the shaft 27 and the stopper 25 rotate in one body. Since the stopper guide 23 is fixed to the hinge body 21 and rotates in one body, the stopper guide 23 and the stopper 25 are relatively rotated in opposite directions.

In addition, a guide protrusion 251 protrudes from an edge of the stopper 25, and the guide protrusion 251 is inserted into the guide hole 231 of the stopper guide 23. The guide protrusion 251 moves along the guide hole 231 and is caught by the stepped portion 232. In addition, in order for the guide protrusion 251 to pass over the stepped portion 232, the force for rotating the display set 13 needs to be slightly increased. As the step portion 232 is formed as described above, the user can sense the degree of rotation while rotating the display set 13. That is, by forming a plurality of stepped portions 232 for each predetermined angle, the user can rotate the display set 13 by a predetermined amount. The total rotation amount of the display set 13 is determined by the length of the guide hole 231. In this embodiment, the display set 13 is shown to rotate up to 190 degrees.

Meanwhile, a washer 24 is interposed between the stopper 25 and the stopper guide 23 to prevent the stopper 25 and the stopper guide 23 from directly contacting and worn.

In addition, one end of the bracket 26 fixed to the display set 13 is disposed outside the stopper 25. The bracket 26 includes a display fixing surface 261 attached to the rear surface of the display set 13 and a bending surface 262 bent from the display fixing surface 261. In detail, an insertion hole 263 through which the shaft 27 is inserted is formed at an end of the bent surface 262. The insertion hole 263 has the same shape as the cross section of the chamfered portion of the shaft 27. Therefore, when the shaft 27 is inserted into the insertion hole 263, the bracket 26 rotates in unison with the shaft 27. In other words, when the display set 13 rotates, the bracket 26, the shaft 27, and the stopper 25 rotate in one body.
