Abstract

A knob structure for use as a switch button of an electronic device or the like is disclosed. The disclosed knob structure includes a body having a coupling hole and a mark member coupled to the coupling hole, wherein a head larger than the diameter of the coupling hole is provided at one end of the mark member so that the head member is coupled to the coupling hole. Characterized by concealing the entrance of the hall. Therefore, by preventing the gap generated between the mark member and the coupling hole from being exposed to the outside, the aesthetics of the knob structure can be kept clean, and the assembly can have a margin in the diameter difference between the mark member and the coupling hole. It can be done easily.

Description

Knob structure

The present invention relates to a knob structure used as a switch button of an electronic device.

In general, the knob structure 10 is used as a switch button of an electronic device, and as shown in FIG. 1, a plurality of coupling holes 11a are formed in a body 11 forming an outer shape, and the coupling holes thereof. It has a structure in which a predetermined mark member 12 is fitted to 11a. Although not shown in the drawing, terminals corresponding to the respective mark members 12 are installed at the lower part of the body 11 so that the corresponding terminals are connected when the mark members 12 are pressed. . That is, the mark member 12 serves as a display for connecting the corresponding terminal.

Such mark member 12 is coupled to the coupling hole (11a) as shown in Figs.

As shown in the drawing, a plurality of protrusions 11b protruding in the radial direction are provided in the coupling hole 11a, and one end of the mark member 12 has a groove portion elastically coupled to the protrusion 11b. 12a) is formed. Therefore, when the mark member 12 is pushed into the coupling hole 11a, the groove portion 12a is elastically coupled to the protrusion 11b.

However, since the mark member 12 makes its outer diameter slightly smaller than the diameter of the coupling hole 11a for smooth coupling with the coupling hole 11a, the inner wall of the coupling hole 11a and the mark member 12 are made. There is a gap between). When a gap is formed in this way, foreign matters are caught in the gap, and there is a problem in that the aesthetics of the knob structure 10 is damaged even when cleaning. On the other hand, when the outer diameter of the mark member 12 is made close to the diameter of the coupling hole 11a in order to minimize the gap, the mark member 12 may not be properly inserted due to the dimension tolerance at the time of manufacture. In addition, since the body 11 is usually manufactured by mold casting, the inlet edge of the coupling hole 11a is not formed at an exact right angle and becomes slightly rounded. Therefore, a gap is inevitably generated between the mark member 12 and the edge of the inlet of the coupling hole 11a.

The present invention has been made to solve the above problems, and an object thereof is to provide a structure improved knob structure to conceal the gap between the mark member and the coupling hole.

The present invention for achieving the above object, in the knob structure including a body formed with a coupling hole, and a mark member coupled to the coupling hole, one end of the mark member is provided with a head larger than the diameter of the coupling hole When the mark member is coupled to the coupling hole, the head portion is configured to conceal the entrance of the coupling hole.

Hereinafter, exemplary embodiments of the present invention will be described in detail with reference to the accompanying drawings.

4 and 5 show a knob structure according to the present invention.

First, referring to FIG. 4, in the knob structure 100 of the present invention, a plurality of coupling holes 111 are formed in a body 110 forming an external shape, and the mark member 120 is coupled to the coupling holes 111. do. A plurality of protrusions 111a protruding in a radial direction are formed in the coupling hole 111, and a groove portion 121 elastically coupled to the protrusion 111a is formed at one end of the mark member 120. It is. In addition, at the other end of the mark member 120, a head portion 122 larger than the diameter of the coupling hole 111 is formed.

When the mark member 120 is inserted into the coupling hole 111, the groove 121 is elastically coupled to the protrusion 111a as shown in FIG. 5, and at the same time, the head 122 is Closing the entrance of the coupling hole 111 will conceal the gap.

Therefore, since the gap between the mark member 120 and the coupling hole 111 is not exposed to the outside, it is possible to eliminate the factor damaging the aesthetics of the knob structure 100.

Meanwhile, in the present exemplary embodiment, the push knob structure provided with the mark member 120 corresponding to the plurality of terminals is illustrated, but it can be effectively applied to combine the mark member with the rotary knob of the dial type. .

As described above, in the knob structure 100 according to the present invention, the gap generated between the mark member 120 and the coupling hole 111 is not exposed to the outside, thereby keeping the aesthetics of the knob structure 100 clean. In addition, it may also have a margin in the difference between the diameter of the mark member 120 and the coupling hole 111 during assembly, there is an advantage that can be performed more easily.
