The present invention relates to an operation lever of a push switch knob such as a computer system, and in particular, a curved structure that can be operated efficiently according to the mounting structure of main components inside the system, and effectively performs its function without deformation due to long use. The operation lever of the knob for the push switch to perform.

The operation lever of the push switch knob is to connect a switch such as a power supply unit mounted on an inner rear part of the system structure and a push knob attached to the front part of the system structure, and various prior arts in the same field to which the present invention belongs ( Example: Republic of Korea Utility Model Publication No. 87-19047) is known, but the operating lever is composed of a number of members, such as iron cores, connecting members, which is not only productive, but also time-consuming during assembly and disassembly, the core core itself is a long time It is easy to be deformed due to the use, and it is difficult to expect accurate performance such as following various problems to use it according to the mounting structure of the system internal device.

Accordingly, the present invention is to provide the operation lever of the push switch knob of the structure to prevent the deformation by unifying the operation lever to a single structure without a number of auxiliary parts and to fit the internal structure of the system in order to improve the above-mentioned disadvantages. The purpose is to.

According to the present invention, it is possible to improve the work efficiency during assembly and disassembly work, and the deformation of the operation lever does not occur even after long-term use. Cost reduction can be achieved.

Hereinafter, the present invention will be described in detail with reference to the accompanying drawings, FIG. 1 is an assembly view of the operation lever of the present invention in a state in which a switch and a knob are connected to each other, mounted on a rear portion of the system, for example, a power supply unit ( 4) Engage and install the operation lever (2) between the switch (1) and the power knob (3) located on the front case surface. In this way, when the user pushes the knob 3, the force is transmitted to the switch 1 through the operation lever 2 so that the switch 1 and the power supply 4 perform an operation function.

At this time, the structure of the lever 2 according to the present invention has a curved shape, which is, as shown in FIG. 1, in the arrangement structure of the device inside the system, the structure of the operating lever 2 according to the design problem This is to compensate for the disadvantage of not being able to make a straight line by a part such as "P".

Therefore, by using the features of the present invention, it is possible to afford a large part of the structural arrangement problem in the design of the system and to efficiently use the internal space. In this case, the most problematic is that the deformation of the member itself or the transmission force may be a problem in use, which may occur in such a curved structure. According to the structure of the present invention, such a problem is sufficiently overcome, and It will be described in detail in FIGS. 2 and 3.

2 is an exploded perspective view of the members of the actuating lever 2 of FIG. 1, which shows the structure of the actuating lever 2 of the present invention. When the material of the actuating lever 2 is made of synthetic resin such as plastic, The coupling part of the switch 1 and the push knob 3 at both ends of the main member of the main member is configured to fit the shape. In particular, the left and right sides of the center of the operating lever 2 are provided with protrusions 5 and 5 'in the longitudinal direction of the lever 2. ). In addition, the upper and lower parts of the operating lever 2 show a shape in which the left and right side surfaces are connected laterally.

Looking at the configuration of each major part of such an operating lever (2) in detail, the front view of the operating lever (2) as viewed from the portion A and the portion engaged with the switch (1) in a square, the center of the lever member of the square is the switch (1) The groove is configured to fit the joint.

In the figure, a square groove is shown so that the shape of the lever 2 engaging portion constituting groove is determined according to the shape of the corresponding portion of the switch 1, wherein the shape of the lever 2 also includes the shape of the engaging portion constituting groove in the system. It can be modified according to the structure of the mounted device.

3B is a cross-sectional view taken along the B-B portion of FIG. 2, showing the configuration of the central portion of the operating lever 2. As shown in FIG.

Protruding portions 5 and 5 'are formed in the lever length direction on the left and right central portions of the H-shaped lever member. These protrusions 5 and 5 'are left and right generated on a relatively long lever 2 located between the knob 3 and the fixed switch 1 when the knob 3 on the first drawing is pushed. It is for canceling the bending force, and it is possible to prevent the left and right deformation of the lever 2 generated during long time use. At this time, as shown in the figure, the protrusion sizes of the protrusions 5 and 5 'are supported by the larger side receiving more force according to the curved shape so that the force pushed from the knob 3 is uniformly transmitted to the switch 1. While minimizing the deformation caused by the left and right bending forces.

At this time, it should be noted that the structure for preventing deformation according to the present invention, when used in a straight lever rather than a curved shape, the left and right bending forces are almost balanced, so that the heights of the deformation preventing protrusions 5 and 5 'are the same.

3c is a rear view of the knob 3 as seen from C. When the knob 3 is pushed, the radially circular portion in the center pushes the tip of the operating lever 2 so that the switch 1 is operated.

The present invention as described above can easily solve the deformation of the member, which is a problem caused by the existing operating lever of the iron core type, and the cost reduction because it performs its function without a separate part only by the operating lever as the shape of the present invention And efficiency can be achieved during assembly and disassembly.
