Embodiment
Refer to Fig. 1, shown a kind of elastic spacing mechanism, its structure comprises: the parts such as back-up ring, upper shell, lower house, large end cap, small end cover, position of the switch swinging block, guide rod, spring, steel ball, euphotic cover, indicator light.
As shown in Figure 1: upper shell 5 is fixed by M3 screw and M3 nut with lower house 12.The first guide rod 6, the second guide rod 7 at right angle settings are in upper shell inside, and guide rod is provided with groove, and two steel ball 9 levels are installed on upper shell inside, in the middle of two steel balls, have a spring 8 to support.When guide rod movement in vertical direction, steel ball and guide rod groove generation relative motion, in steel ball enters groove, by the effect of spring force, closely cooperate steel ball and groove, plays spacing effect.The first guide rod 6 upper surfaces are threaded connection fixing to euphotic cover 4 and large end cap 3; The second guide rod 7 upper surfaces are threaded connection fixing small end cover 2.Two lower end of the guide rod faces are provided with location hole, adopt two pins 10 that guide rod is connected with position of the switch swinging block 11, and in guide rod motion process, position of the switch swinging block swings thereupon.Operating switch 13 is installed on lower house 12 by two screws, and switch knob is placed in swinging block inside, the position of the switch, in the time that position of the switch swinging block swings, drives the conversion of operating switch handle position.Indicator light 14 levels are installed on upper shell side, and indicator light is by euphotic cover and large end cap printing opacity, indicator cock present position state.
Refer to Fig. 3, described this mechanism's indicator cock position principle.Guide rod middle part hollow out forms indicator light groove is installed, and indicator light is vertically put into guide rod side indicator light groove is installed, and in guide rod motion process, indicator light is all the time in guide rod inside; Guide rod end face interference fit is installed euphotic cover, and the illumination intensity of disperse indicator light makes illumination more even; Guide rod end face surrounding is provided with external screw thread, and large end cap and guide rod through threaded are fixed, and large end cap centre and surrounding design loophole, play the effect of indicator cock location status.Large end cap 3 is installed back-up ring 1 around, and back-up ring 1 is fixed on upper shell 5.
Refer to Fig. 5, described this organization switch position swinging block structure.As shown in Figure 5, this mechanism to press stroke relevant with angle in figure (166 °), the stroke of pressing of different angle design Hui Shigai mechanisms changes.It is relevant that position of the switch swinging block pendulum angle (24 °) and switch are pulled angle, need to pull angle adjustment according to the difference of switch.
According to man-machine work efficiency, human body list refers to the requirement of push switch pressing force in (2.8～11) N scope, designs the pressing force of spring.The minimum service load F of design spring
1=(4 ± 0.5) N, working ultimate load F
2=(11 ± 0.5) N, can meet man-machine work efficiency requirement, according to the requirement of installing space, and spring maximum outside diameter φ=6.3, two ends are also tight, polish for two steel balls are installed.
Below only expressed execution mode of the present utility model, it describes comparatively concrete and detailed, but can not therefore be interpreted as the restriction to utility model patent scope.It should be pointed out that for the person of ordinary skill of the art, without departing from the concept of the premise utility, can also make some distortion and improvement, these all belong to protection range of the present utility model.Therefore, the protection range of the utility model patent should be as the criterion with claims.
Advantage of the present utility model: simple in structure, convenient to operation.Elastic spacing mechanism press surface is provided with protection back-up ring, prevents from operating misoperation, improves the fail safe of operation.In elastic spacing mechanism, be provided with indicator light, realize the operational requirements to switch under different luminous environment conditions.
