Abstract
The utility model provides a stroke switch driving device comprising a rack, a contact arm, a lever machine and a restoring extension spring. The contact arm and the lever machine are rotatably arranged on the rack, a cam is employed as the contact arm, and a lever is employed as the lever machine. A second roller is arranged between the contact arm and the lever machine, and the side surface of the second roller is abut against the driving arm of the contact arm and the driving arm of the lever machine. At least one end of the second roller is slidably arranged in a first sliding groove mounted on the rack. The second roller is the follower of the contact arm, and transmits the motion of the contact arm to the lever machine. The resisting arm of the lever machine drives a stroke switch contact to move through a first roller. One end of the restoring extension spring is fixed to the rack, and the other end of the restoring extension spring is fixed to the contact arm, so that contact arm can be restored. The stroke switch driving device has a strong adaptive capability and a wide triggering scope, so that a main switch can reliably trigger the stroke switch all the time when the main switch moves forward or back, and correct signals can be provided for a control system.
Description
Technical field
The utility model relates to can shifting type metal closed switch apparatus field, is specifically related to a kind of travel switch drive unit.
Background technology
Travel switch claims again position switch, is a kind of switchette electrical equipment that gathers moving component position signalling.Can shifting type metal closed switch apparatus mainly by can withdraw-type main switch and cabinet form, can in cabinet, have test position and service position two states by withdraw-type main switch, be the position signalling of Obtaining Accurate main switch, conventionally can in cabinet, equip travel switch.
For the flexibility of guaranteeing that main switch moves in cabinet, main switch and cabinet are larger in the fit clearance of the non-direction of motion, and main switch, in the process of advancing or retreating, has larger skew space, left and right, cause reliably touching travel switch, for control system provides wrong signal.This problem is prevalent in can shifting type metal closed switch apparatus field.
Utility model content
The utility model is for above-mentioned the deficiencies in the prior art, provide a kind of adaptive ability strong, touch the travel switch drive unit of wide ranges.
The utility model is achieved by the following technical solution:
A travel switch drive unit, is characterized in that, comprises frame, contact arm, thick stick machine and reset tension spring, and contact arm and thick stick machine be rotating being arranged in frame all, and described contact arm is a cam, and described thick stick machine is a lever; Between contact arm and thick stick machine, be provided with the second roller, the equal butt of power arm of the side of described the second roller and contact arm and thick stick machine, at least one end of the second roller is slidably arranged in the first chute arranging in frame, the second roller is the driven member of contact arm, for the motion of contact arm is delivered to thick stick machine; The resistance arm of described thick stick machine drives travel switch contact action by the first roller; One end of reset tension spring is fixed in frame, and the other end is fixed on contact arm, for the reset of contact arm.
Further setting of the present utility model is, at least one end of described the first roller is slidably arranged in the second chute arranging in frame, the resistance arm of the side of the first roller and thick stick machine and the equal butt of travel switch contact.
Further setting of the present utility model is, described contact arm is arranged in frame by the second rotating shaft is rotating.
Further setting of the present utility model is, thick stick machine is arranged in frame by the first rotating shaft is rotating, and described the first rotating shaft is the fulcrum of thick stick machine.
Travel switch drive unit described in the utility model is by the swing under external force of this cam structure of contact arm, transmit motion to thick stick machine, thick stick machine can swing around the shaft when stressed, further transmits motion to travel switch contact, thereby has realized the driving to travel switch.Because contact arm described in the utility model has certain length, when main switch left and right side-play amount is larger, still can touch with contact arm, thereby trigger travel switch; The adaptive ability of the trip driving mechanism for switch is strong, touch wide ranges, can guarantee that main switch is in the process of advancing or retreating, and reliably touches all the time travel switch, for control system provides correct signal.
Accompanying drawing explanation
Fig. 1 is the structure chart of travel switch drive unit described in the utility model;
Fig. 2 is the structure chart of handcart push pedal while not contacting with contact arm;
Fig. 3 is the structure chart of handcart push pedal while contacting with contact arm;
Number in the figure part is respectively:
1 travel switch, 2 travel switch contacts, 3 first rollers, 4 first rotating shafts, 5 thick stick machines, 6 second rollers, 7 second rotating shafts, 8 contact arms, 9 handcart push pedals, 10 reset tension springs, 11 frames, 12 first chutes.
Embodiment
Below in conjunction with the drawings and specific embodiments, the utility model is described in more detail.
As shown in Figure 1, 2, the utility model provides a kind of travel switch drive unit, for triggering by handcart push pedal 9 operating mechanism that drives travel switch 1, triggers travel switch contact 2.
Described travel switch drive unit comprises frame 11, contact arm 8, thick stick machine 5 and reset tension spring 10, and described contact arm 8 is arranged in frame 11 by the second rotating shaft 7 is rotating, and described contact arm 8 is a cam.
Between contact arm 8 and thick stick machine 5, be provided with the second roller 6, the equal butt of power arm of the side of described the second roller 6 and contact arm 8 and thick stick machine 5, at least one end of the second roller 6 is slidably arranged in the first chute 12 arranging in frame 11.
The resistance arm of described thick stick machine 5 drives 2 actions of travel switch contact by the first roller 3; Concretely, at least one end of described the first roller 3 is slidably arranged in the second chute arranging in frame 11, the resistance arm of the side of the first roller 3 and thick stick machine 5 and the equal butt of travel switch contact 2.
One end of reset tension spring 10 is fixed in frame 11, and the other end is fixed on contact arm 8, for the reset of contact arm 8.
The course of work of travel switch drive unit described in the utility model is:
As shown in Figure 3, handcart push pedal 9 is moved along A direction, and contact arm 8 clockwise rotates, and drive thick stick machine 5 counterclockwise to rotate (being B direction) around fulcrum, thereby the resistance arm of thick stick machine 5 drives travel switch contact 2 to move along C direction by the second roller 6.
It is apparent to one skilled in the art that the utility model can be changed into various ways, and such change is not thought and departed from scope of the present utility model.All so apparent modifications of the technical staff to described field, within being included in the scope of this claim.
