Abstract
Utility model discloses a kind of switch plunger mechanism, it is characterized in that: comprise switch case, rotary cylinder and push rod, the top of switch case is provided with pilot hole, described push rod is directed in switch case by pilot hole and carries out rotating and moving up and down, the mid portion that described push rod is positioned at switch case inner chamber is fixed with horizontal bearing pin, roller is installed at the axle two ends of horizontal bearing pin, the edge cam curved surface that the rolling surface of roller and described switch case inner chamber upper surface are provided with is just right, be fixedly connected with by coupling band with described rotary cylinder after the upper rod end of described push rod upwards passes the top of switch case, the bottom of coupling band is provided with back-moving spring, under the effect of back-moving spring, coupling band upwards pulls push rod to make roller all the time against described edge cam curved surface.The utility model, for the power control switch of low-tension switch cabinet, has pneumatic control, flexible movements, advantage that Reliability of Microprocessor is strong.
Description
Technical field:
The utility model relates to a kind of low-tension switch cabinet power control switch, is specifically related to a kind of switch plunger mechanism of control switch.
Background technology:
The power control switch applied in low-tension switch cabinet, although structural shape has various, but there is the shortcomings such as action is dumb, Reliability of Microprocessor is not strong in various degree, this is because the design of the switch plunger mechanism of power control switch is reasonable caused not, also have, the switch plunger mechanism of power control switch generally adopts Non-follow control, can not meet the work requirements of some particular job occasion.
Summary of the invention:
For the deficiencies in the prior art, the purpose of this utility model is to provide a kind of power control switch for low-tension switch cabinet, has the switch plunger mechanism of pneumatic control, flexible movements, the strong advantage of Reliability of Microprocessor.
The utility model takes following technical scheme:
A kind of switch plunger mechanism, it is characterized in that: comprise switch case, rotary cylinder and push rod, the top of switch case is provided with pilot hole, described push rod is directed in switch case by pilot hole and carries out rotating and moving up and down, the mid portion that described push rod is positioned at switch case inner chamber is fixed with horizontal bearing pin, roller is installed at the axle two ends of horizontal bearing pin, the edge cam curved surface that the rolling surface of roller and described switch case inner chamber upper surface are provided with is just right, be fixedly connected with by coupling band with described rotary cylinder after the upper rod end of described push rod upwards passes the top of switch case, the bottom of coupling band is provided with back-moving spring, under the effect of back-moving spring, coupling band upwards pulls push rod to make roller all the time against described edge cam curved surface.
Adopt after technique scheme, the utility model can realize pneumatic control, and has flexible movements, advantage that Reliability of Microprocessor is strong.Because the energising of switch is that the push rod that produced by rotation and the rotation of push rod moves up and down that action come with disconnecting, switch is when "off" position, push rod is in upper limit position, and when switch need switch on power, rotary cylinder ventilation action (realizing pneumatic control), push rod can be driven to rotate, push rod then drives roller to roll on edge cam curved surface, push rod is moved down while rotation, so push rod drives binding post contact to make switch be in "on" position, because push rod has roller with rotating when rotating, not only effectively ensure that the flexibility of switch motion, and effectively can ensure the reliability of switch motion.
Accompanying drawing illustrates:
Fig. 1 is structural representation of the present utility model.
Embodiment:
As shown in the figure, switch plunger mechanism of the present utility model, comprise switch case 5, rotary cylinder 1 and push rod 9, the top of switch case 5 is provided with pilot hole, described push rod 9 is directed in switch case 5 by pilot hole and carries out rotating and moving up and down, the mid portion that described push rod 9 is positioned at switch case 5 inner chamber is fixed with horizontal bearing pin 8, roller 7 is installed at the axle two ends of horizontal bearing pin 8, the edge cam curved surface 6 that the rolling surface of roller 7 and described switch case 5 inner chamber upper surface are provided with is just right, be fixedly connected with by coupling band 2 with described rotary cylinder 1 after the upper rod end of described push rod 9 upwards passes the top of switch case 5, the bottom of coupling band 2 is provided with back-moving spring 3, under the effect of back-moving spring 3, coupling band 2 upwards pulls push rod 9 to make roller 7 all the time against described edge cam curved surface 6.Switch is when "off" position, push rod is in upper limit position, the low point cantact of roller and edge cam curved surface, and when switch need switch on power, rotary cylinder ventilation action, push rod can be driven to rotate, and push rod then drives roller to roll on edge cam curved surface, push rod is moved down while rotation, so push rod drives binding post contact, that switch is conductively connected is logical.
