Description

Button Handle for Panel Switch {Button Handle for Panel Board}

The present invention relates to a push button of a handle for a switchgear installed in switchboards of various indoor and outdoor communication equipments, and more particularly, a simple structure makes the manufacturing process simple and smooth, and the handle for the switchgear can be fixed and released. It relates to a push button of the handle for the switchboard.

In general, the handle installed in the switchboard or the control panel is configured to freely operate the knob as the knob is disassembled by a push button installed in the knob.

The push button for restraining and releasing the knob as described above is provided with a button case accommodated in the handle casing, a latch body built into the button case for vertical movement, and a push hole connected to the latch body for horizontal movement. It is composed of an elastic spring having an elastic force lifting upwards for the vertical movement of the lev, and a buffer spring having an elastic force pushed in a horizontal direction to induce horizontal movement of the pressing hole. In this conventional configuration, when the presser is pressed, the pusher retreats backward, and at this time, the shock absorbing spring supported on the rear side is compressed, and the elastic spring is compressed while lowering the latch body engaged with the presser. Accordingly, the knob coupled to the latch body is released and at the same time, the handle is manipulated to achieve the fixation and release of the door of the control panel or the control panel. On the other hand, if the pressing force is removed, the pressing sphere protrudes forward by the restoring force of the shock absorbing spring, which acts in the horizontal direction from the rear of the pressing sphere, and returns to its original state. At the same time, the latch body is raised by the restoring force of the elastic spring, thereby restoring the original state. Is achieved.

However, the conventional push button as described above has been reduced in productivity due to the complexity and inconvenience of parts processing due to the need for several parts, and the difficulty of assembly due to the cumbersome work of installing the spring because the springs facing the presser and the latch body are arranged separately. Following this, there is a problem that the maintenance of the repair is inconvenient and difficult due to the complicated structure due to the use of excessive parts.

The present invention was devised to solve such a conventional problem, and has a simple structure, which simplifies the assembly labor and reduces the assembly time, thereby improving productivity and achieving good and safe operation even with a small number of parts. It is to provide a push button of the handle for the switchboard.

In order to achieve the above object, the present invention provides a push button for controlling a knob of a handle body installed on a lid of a switchboard or a control panel, the lower portion of the handle body being accommodated in a storage room having a predetermined depth and being disposed therein. A button case which accommodates the inclined surface formed at the center of the latch body and the inclined surface provided on the operation shaft of the pressing hole in a state of inclined contact with the built-in latch body at right angles, and the bottom surface of the handle body at the bottom of the latch body. It is achieved by the push button of the handle for the switchboard comprising an elastic spring having an elastic force which is supported on and pushes the latch body upward.

The end of the operating shaft of the push button coupled to the latch body embedded in the button case protrudes to one side of the latch body and is fixed by a snap ring.

Hereinafter, the most preferred embodiments will be described in detail with reference to the accompanying drawings so that those skilled in the art can easily implement the present invention.

1 is a perspective view of a handle to which the present invention is applied, FIG. 2 is an exploded perspective view of a push button according to the present invention, and FIG. 3 is a longitudinal sectional view of a handle showing a push button state according to the present invention.

The push button of the handle for the switchboard is a handle body 10 is installed on the door (not shown) of the switchboard or the control panel, as shown in Figure 1, the long knob installation groove 60 on the front of the handle body (10) Formed. The lower end of the knob installation groove 60 is provided with a knob 30 and a push button 20 to control the knob 30.

The push button 20 is embedded in the button case 12 and operated in the vertical direction to restrain the lower end of the knob 30 and the press corresponding to the latch body 40 and flowing in the horizontal direction. It consists of a sphere 50.

The latch body 40 restrains the lower end of the knob 30 and is pushed from the bottom to the upper side, and an elastic spring 44 having elastic force is supported and connected to the bottom of the knob installation groove 12, and the upper protrusion 46 is connected to the bottom of the knob 30. Exposed to the outside of the button case 12 is lowered when the lower end of the knob 30 is pressed or lowered by the operation of the pusher (50). Further, a 45 ° inclined surface 42 is provided on the bottom of the inner receiving groove 48.

The pusher 50 is provided with a working shaft 52 in the longitudinal direction and is integrally provided with the working shaft 52 and a 45 ° inclined surface 54 is inclined in contact with the inclined surface 42 at an end thereof. have. In addition, the end of the operating shaft 52 is protruded to one side of the latch body 40 and is fixed by a snap ring 56.

The push button 20 configured as described above inserts a horizontal pusher 50 perpendicular to the latch body 40 placed in a vertical state in the button case 12 and is formed at a center of the latch body 40 by 45 °. The inclined surface 42 is inserted into the latch body 40 such that the 45 ° inclined surface 54 provided on the operation shaft 52 of the pressing hole 50 is in contact with the slope, and is lifted vertically from the bottom of the latch body 40. The main body is inserted into the lower part of the latch body 40 while being pressed into the lower part of the latch body 40 while being in close contact with the bottom surface of the knob installation groove 60 via the elastic spring 44 having elastic force, so that the pusher 50 is operated. The 45 ° inclined surface 42 of the latch body 40 in oblique contact with the 45 ° inclined surface 54 on the shaft 52 corresponds to the latch body 40 to be retracted downward from the vertical line so that the protrusion 46 is turned into a knob ( 30 is released from the lower portion and when the release of the pressing holes 50 is released from the lower end of the latch body 40 to give an elastic force in the vertical direction Due to the holding force of the spring 44, the latch body 40 is charged to the upper portion, and accordingly, the inclined surface 54 of the pusher 50 is diagonally coupled with the 45 ° inclined surface 42 of the latch body 40. By pressing the presser 50 is restored to its original state. Here, the restoring force of the pressing holes 50 is 45 ° inclined plane 42 and an oblique line when the latch body 40 is advanced upward by the return force of the elastic spring 44 which is purely supported on the bottom surface of the latch body 40. The inclined surface 54 provided at the lower end of the operating shaft 52 of the pressing hole 50 in surface contact is operated while sliding.

Therefore, it is possible to restore the two parts of the pressing hole 50 and the latch body 40 only by the elastic spring 44 which is installed to operate in one direction at the same time, thereby reducing the number of parts and simplifying the structure while maintaining a good restoring force. This makes the control of the knob 30 is accurate and safe.

The present invention as described above makes the latch body and the pressing hole sloped and has a restoring force of the latch body and the pressing hole with only a small force of a single elastic spring lifted from the lower side, thereby reducing the number of parts while reducing the number of parts, thereby reducing the assembly labor. Economical production is achieved, and in the event of a breakdown, it is possible to easily and easily carry out repair inspection, thereby achieving continuous use, thereby improving product reliability.
