Fig. 2 is the position signalling flip flop equipment of a kind of sealing of providing of the utility model view when triggering.
Embodiment
Below in conjunction with the drawings and specific embodiments the utility model is further described.
As depicted in figs. 1 and 2, the position signalling flip flop equipment of a kind of sealing provided by the utility model, the flip flop equipment that comprises pedestal 12, is located at the approach switch 1 on the pedestal 12 and matches with approach switch 1; Signal mask 3 and baffle plate supporting seat 4 that flip flop equipment comprises axle 10 and is sleeved on axle 10 tops, the bottom of axle 10 is stretched out in the sleeve 11 on the pedestal 10 and is passed the hole that is located on the pedestal 10 from being located at; Axle 10 has first shaft shoulder, second shaft shoulder from top to bottom, and baffle plate supporting seat 4 is located on the axle 10 on first shaft shoulder.
As shown in Figure 2, generally, when the position signalling flip flop equipment is located at pedestal 12 tops (being Polluted area), when detected equipment 13 is located at pedestal 12 belows (being the safety zone), analyze as can be known, the possible leakage path of dusty gas is: dusty gas enters from A or B place, reveals by the gap between axle 10 and the baffle plate supporting base 4; Dusty gas enters from C, reveals by the gap between axle 10 and the sleeve 11.
Improvement of the present utility model is, between the end face of first shaft shoulder on baffle plate supporting seat 4 and the axle 10 sealing gasket 5 is set; And, between baffle plate supporting seat 4 and sleeve 11, arrange and be sleeved on the axle 10 and with the flexible sealing shroud 7 of axle 10 motions, the middle part of flexible sealing shroud 7 has one section scalable architecture, its two ends have the chimb that extends out, the chimb of flexible sealing shroud 7 one ends is fixed on the lower surface of baffle plate supporting base 7 by screw and gland 6, the chimb of the other end is fixed on the upper surface of sleeve 11 by screw and gland 6, like this when axle 10 moves up and down, flexible sealing shroud 7 is done stretching motion with axle 10, no matter guarantee it is stationary state or motion state, dusty gas is not all revealed.
By adopting the said structure setting, when dusty gas enters from A, prevent that by sealing gasket 5 dusty gas from entering; When dusty gas enters from B or C place, by flexible sealing shroud 7 with the dusty gas isolation, thereby blocked all possible leakage approach.
In addition, be provided with the spring 9 that is wrapped on the axle 10 between the bottom of axle 10 and the sleeve 11; One end of spring 9 is against on the step of being located in the sleeve 11, and the other end is against the second shaft shoulder place on the axle 10.
Also be provided with support plate 2 on the pedestal 12, the bottom of support plate 2 is fixed by screws on the pedestal 12.Approach switch 1 is to dock the detecting sensor that puts in place, and approach switch 1 is fixed on the top of support plate 2 by two nuts.
Under the preferable case, the middle part of axle 10 is provided with spacing hole 14, and the top of sleeve 11 is provided with pin-and-hole and passes pin-and-hole and pass the spacer pin 8 in axle 10 upper limit holes 14; When axle 10 moved to the limes superiors position, spacer pin 8 was positioned at the lower end of spacing hole 14; When axle 10 moved to the smallest limit position, spacer pin 8 was positioned at the upper end of spacing hole 14.
The spacer pin 8 here has two functions: the firstth, and guiding prevents that axle 10 from producing rotation, the signal mask 3 that causes being fixed on axle 10 upper ends departs from assigned address, can't trigger approach switch 1; The secondth, spacing, axle 10 moved up and down travel limits in the stroke in axle 10 upper limit holes 14, namely be not subject in the External Force Acting situation in system, the distance that restrictive axes 10 moves downward under spring 9 effects, when axle 10 is subject to upwards thrust that detected equipment 13 applies, limit the limes superiors position of axle 10 motions by spacer pin 8, so that detected equipment 13 moves when putting in place, axle 10 is pushed to limes superiors location triggered approach switch 1, the movement position of the detected equipment 13 of control prevents mechanical collision simultaneously.
During the utility model work, at first so that detected equipment 13 when moving to assigned address, apply acting force in the lower shaft end of axle 10, with axle 10 jack-up upwards, signal mask 3 moves to the limes superiors position with axle 10, simultaneously by adjusting the horizontal level of approach switch 1, makes signal mask 3 reach the operating distance that triggers approach switch 1, approach switch 1 is triggered, and sends the signal that puts in place; When detected equipment 13 is not in place, be applied to the lower shaft end of axle 10 without external force, under the effect of self gravitation and spring 9, axle 10 moves downward to the smallest limit position, and signal mask 3 is away from approach switch 1.
Structure described in the utility model is not limited to the embodiment described in the embodiment, and those skilled in the art draw other embodiment according to the technical solution of the utility model, belong to equally technological innovation scope of the present utility model.
