Abstract
The utility model relates to an input protection device of a controller, which is characterized in that the input protection device comprises a mounting plate (3) and a pressure plate (1) which is arranged on the mounting plate (3), a first inversed T-shaped hole (3a) is arranged on the mounting plate (3), a second inversed T-shaped hole (1a) which is opposite to the first inversed T-shaped hole (3a) is arranged on the pressure plate (1), a protection press button (2) is arranged on the second inversed T-shaped hole (1a), and the lower surface of the pressure plate (1) is adhered with an elastic pasting pad (6). With the technical proposal, splashing matters which are produced in the process of production do not easily and directly damage the input press button and a key press circuit board of the controller under underground production operation environment, thereby achieving the purpose of protecting the input press button and the key press circuit board. The utility model has the advantages of simple structure, convenient dismounting and strong practicability.
Description
Technical field
The utility model relates to a kind of input protection device of controller.
Background technology
At present, the load button of most of controllers is to be made and the button that is provided with for absolute construction each other by hard material, and button location lid is pulled the gap that is arranged between button to be constituted, and is provided with caoutchouc elasticity return spare between each button bottom and printed circuit board (PCB).This structure keyboard is if will guarantee the button regular event, must reserve certain clearance between its each button and button location cover plate, because thereby dust very easily falls into the useful life that keyboard has influenced keyboard greatly by this gap, especially, if controller is to be in the downhole production operating environment, the splash that produces in the production process is very easily beaten on the load button of controller, even liquid is splashed in the load button, cause and damage load button and button circuit board, and then the damage controller, have a strong impact on the ordinary production of down-hole.
The utility model content
The purpose of this utility model is to provide a kind of input protection device of controller, can play protective action to controller load button and button circuit board.
For achieving the above object; the utility model mainly is that an input protection device is installed outside the input keyboard of original controller; reach the purpose that input keyboard is protected by this input protection device; concrete technical scheme is as follows: be made up of mounting panel and the pressing plate that is positioned at this mounting panel top; mounting panel is provided with the first inverted T shape hole; relatively be provided with the second inverted T shape hole with this first inverted T shape hole on the described pressing plate; be provided with the protection button in this second inverted T shape hole, the lower surface of this pressing plate is pasted with the elasticity pad pasting.
As preference, for further protection load button, button circuit board and purpose attractive in appearance, the top of above-mentioned pressing plate is provided with panel, and this panel is relative with the described second inverted T shape hole is provided with perforation, is provided with facial mask between this panel and the described pressing plate.Corresponding key symbols mark is made in position at original relatively keyboard on the facial mask, by the panel of facial mask top facial mask is fixed then, and panel reveals sign flag having the position of sign flag to have perforation on the facial mask relatively.
As another preference, for the comfortableness of operating, above-mentioned protection button top cambered surface spherical in shape, the bottom of this protection button is provided with boss, comes and original button butt by this boss, can increase the sensitivity of operation.
As another preference, the lower end of above-mentioned mounting panel is provided with the boss swivel nut, and the outer end of this boss swivel nut is provided with step.The boss swivel nut had both played the purpose of mounting screw, can adjust the distance of protection button and original button again by the boss swivel nut.
The utility model has the first inverted T shape hole on mounting panel; originally button is contained in this first inverted T shape hole; one pressing plate is installed on the mounting panel; pressing plate is provided with a plurality of second inverted T shape holes; the protection button is positioned in the second inverted T shape hole of pressing plate; by the elasticity pad pasting protection button is sticked in the second inverted T shape hole again, with guarantee the protection button can only be in the second inverted T shape hole of pressing plate axial minute movement, carry out input operation by the button on the protection button conflict button circuit board.When installing, the button with on the following inverted T shape hole alignment controller input keyboard on the mounting panel is installed in the input protection device on the housing of controller through screw then.
Owing to adopted such scheme, under the downhole production operating environment, the splash of kicking up that produces in the production process is difficult for directly injuring the load button and the button circuit board of controller, and the damage controller, thereby reach the purpose of protecting load button and button circuit board; And the utility model is simple in structure, and convenient disassembly is practical.
The utility model is described in further detail below in conjunction with drawings and Examples.
