Button device

The present invention relates to a button device, and more particularly to a button device that is waterproof and dustproof, and the button setting is easy to change.

At present, in the operation interface of the general industry, the push-type operation is still in the bulk, and the conventional push-type operation is, for example, a common button device. The button device usually includes a panel having a plurality of perforations, and the plurality of panels are respectively behind the panel. a circuit board having the perforations, and a circuit board having a plurality of trigger portions corresponding to the respective buttons and being screwed on the rear side of the panel, the user is activated by pressing the buttons to trigger the trigger circuit board The function set.

However, the disadvantages of the conventional button device are:

1. No waterproof, oil-proof, dust-proof, anti-air function: in order to avoid the buttons falling, the buttons are inserted into the perforations from the rear side of the panel, so the perforations and the slits between the buttons It is easy to seep, ooze, drop dust, and air in and out, so that the rear circuit board is easily short-circuited by water, oil, dust, or damaged by air oxidation.

Second, the button setting layout is fixed: since the panel and the buttons are screwed together with the circuit board, the button position is not easily Adjust to meet user needs.

Third, the installation and maintenance is not easy: because the buttons are worn by the rear side of the panel, and the panel, the buttons and the circuit board are screwed together, when the button is damaged to be repaired, the panel must be removed together And the circuit board is not only inconvenient, but also increases maintenance time and cost.

Therefore, the object of the present invention is to provide a button device which is waterproof and dustproof and whose button setting is easy to change.

Therefore, the new button device is suitable for being mounted on a panel having a perforation, the button device comprising a waterproof elastic groove, a pressing block, and a fixing frame.

The waterproof elastic groove is made of a waterproof flexible material, and is pierced through the perforation of the panel and includes the bottom wall of the rear side of the panel, a peripheral wall extending from the periphery of the bottom wall toward the front of the panel, and Abutting flange extending outwardly from the leading edge of the peripheral wall and abutting against the front side of the panel.

The pressing block is received in the waterproof elastic groove, and is suitable for pressing by the user, and is pressed against the bottom wall of the waterproof elastic groove when pressed.

The fixing frame includes a frame body embedded between the waterproof elastic groove and the pressing block, and the frame body respectively abuts the waterproof elastic groove and the pressing block.

The utility model has the advantages that: the waterproof elastic groove is designed to pass through the perforation of the panel and the perforation is closed, and the waterproof elastic groove, the pressing block and the fixing frame are designed as a simple mechanical combination, thereby achieving good performance. Waterproof, oil-proof, dust-proof, and reduce the efficiency of air in and out, and the layout and arrangement of the button devices can be arbitrarily changed according to actual needs.
