A kind of microswitch protective cover proposed by the present invention, including shield body, the side of the shield body are set
There is opening, the shield body is provided with the annular seal space with open communication, is bonded with the both sides inwall of the annular seal space
Slide rail, sealing plate is provided between two slide rails, and sealing plate closure opening, the bottom of the sealing plate are provided with clamp,
The both ends of the clamp are stuck in slide rail and are slidably connected with the inwall of slide rail, and a side bottom of the sealing plate is provided with fixation
Bar, one end of the fixed strip extend to the outside of shield body, the crown center position peace of the sealing plate by opening
Equipped with fixed block, the top both sides of the fixed block are rotatablely equipped with elastic rod, the top both sides inwall of the annular seal space it
Between be connected with horizontally disposed sliding bar, two sliding blocks are arranged with outside the sliding bar, one end of the sliding block and elastic rod turns
It is dynamic to connect, spring is equipped between two sliding blocks with two mutually remote sides of sliding block, and spring housing is outside sliding bar.
Preferably, the centre position of the sliding block offers slide opening, wherein offers neck on the both sides inwall of slide opening,
Roller ball is slidably fitted with neck, a part for roller ball extends to neck, and roller ball is slidably connected with sliding bar.
Preferably, the elastic rod and sliding bar form isosceles triangular structure, and the total length of two elastic rods is less than
The length of sliding bar.
Preferably, its length of two sliding blocks mutually close to side is less than two sliding blocks mutually bullet away from side
Spring length.
Preferably, side of the clamp away from sealing plate is bonded with rubber mount, and the width of clamp is more than opening
Width.
In the present invention, a kind of microswitch protective cover blocks switch/inlet using sealing plate, and on fitted seal plate
During drawing, elastic rod is driven, in being horizontally slipped on sliding bar, to facilitate sealing plate to open and close in the presence of elasticity, and
Without using when closure be open, prevent from entering inside microswitch that ash charge is heavy and liquid, security performance is high, improves the protective cover
Use quality, reasonable in design, simple to operate, good sealing effect of the invention, and convenient use, improve the use matter of the protective cover
Amount.
