Embodiment
Below in conjunction with Figure of description, the utility model is described in detail.
As shown in Figure 1 and Figure 2, the anti-fracture foot switch that the utility model provides comprises base 20, pedal 30 and cover plate 10.
The front end of base 20 is protruding with the uncovered housing in upper end 21, housing 21 internal fixtion has support 22, support 22 is fixed with sensitive switch 24, the drive rod of sensitive switch 24 is arranged down, the both sides, front end of pedal 30 are protruding with support arm 32, the two sides, front end of support arm 32 have through hole, rotating shaft 31 runs through the left and right side of housing 21, its external part is through the through hole on support arm 32, and be fixed by bolt in outer face, the left and right side of housing 21 is respectively equipped with block 25, under normal condition, the front end of support arm is resisted against on the end face of block 25, play the effect of support and ensure its stability.Rotating shaft 31 is fixed with plectrum 26, plectrum 26 is positioned at the below of the drive rod of sensitive switch 24, moves up for stirring drive rod, and mobile certain stroke distances, sensitive switch 24 action, controls the Kai Heguan of its circuit or equipment.
Composition graphs 2, Fig. 3 again, one end face of housing 21 has screwed hole, the inner side of end face, the bottom surface of housing 21 is provided with square boss, and this square boss is fixed by grounding screw 42, and Line pressing buckle 41 is fixed on the top of square boss, the positive double thread hole of arcuate socket between Line pressing buckle 41 and square boss, cable joint 40 is screwed in screwed hole, is the cooperation of tightening seal, and cable joint 40 connects sensitive switch 24 by circuit through Line pressing buckle 41.
The end face of base 20 is also provided with bolt 51; bolt 51 is arranged on the below of pedal 30; bolt 51 is not caused the excessive action of sensitive switch 24 and damages by the stroke of control pedal 30; play the effect of protection; bolt 51 is set with back-moving spring 50, back-moving spring 50 utilizes the elastic restoring force of itself to return to original position after pin is stepped on.
Composition graphs 1, Fig. 2, Fig. 4, the front end of cover plate 10 is provided with the upper cover 11 suitable with housing 21, both are one-body molded, cover plate 10 to be inclined upwardly setting relative to the end face of upper cover 11, increase the gradient, to increase the space of foot pedal 30, eliminate the limitation can not carrying out because the large footwear of pin are large operating, cover plate 10 by spaced groove and fin one-body molded, form setback face, with increase cover plate 10 by force intensity, cover plate 10 hides above pedal 30, play the effect of protection pedal 30, upper cover 11 is fixed on the opening end of housing 21, and and be provided with sealing gasket 23 between housing 21, sealing gasket 23 ensures upper cover 11 and housing 21 excellent sealing, prevent because of poorly sealed generation noise.The bottom surface of base 20 is provided with four little rubber antiskid pads 28, not only saves material cost, also changes bottom friction power, strengthens skidproof effect.
Shown in composition graphs 1, Fig. 3, Fig. 4, in the middle part of the other end of housing 21, interval is provided with two the first reinforcements 27 through extending, first reinforcement 27 is in trapezoidal tabular, first reinforcement 27 is arranged on the both sides of bolt 51, and the first reinforcement 27 is in order to increase bond strength between pedal 30 and base plate 20 and fastness.The bottom surface of cover plate 10 and the intersection of upper cover 11 are provided with multiple second reinforcement 12, and misplacing with the first reinforcement 27 is oppositely arranged, and the second reinforcement 12 is in order to increase bond strength between cover plate 10 and upper cover 11 and fastness.
