Abstract

The utility model relates to a kind of novel banister of keeping off a car.A kind of novel banister of keeping off a car, the pin comprising motor and be connected with motor, described motor is connected with electronic relay, and electronic relay is connected with travel switch.The utility model structure is simple, reasonable in design, convenient and swift to banister transformation of keeping off a car of the prior art, improves the application life of banister of keeping off a car, reduces the frequency of maintenance of banister of keeping off a car.

Description

A kind of novel banister of keeping off a car
Technical field
The utility model relates to a kind of novel banister of keeping off a car.
Background technology
Realization of keeping off a car banister limit function of the prior art adopts electromagnetic induction more, when vehicles passing in and out is more, because barrier operation of keeping off a car is frequent, induced magnet can be caused to be shifted, make spacing inefficacy, banister of keeping off a car cannot normally work, and affects vehicles while passing; And spacing malfunctioning meeting causes keeping off a car banister internal loading electric current comparatively greatly, burns circuit board.
Banister of keeping off a car of the prior art, electronic relay is directly connected with motor, under special circumstances, is easy to occur that electric current burns the situation of circuit board.The utility model adds A.C. contactor between electronic relay and motor, once there is the situation that electric current is excessive, A.C. contactor disconnects, and circuit breaker, the safety factor of circuit board improves greatly.
Preferably, described A.C. contactor is CJ20 A.C. contactor.
Compared with prior art, tool has the following advantages the utility model: structure is simple, reasonable in design, convenient and swift to banister transformation of keeping off a car of the prior art, improves the application life of banister of keeping off a car, reduces the frequency of maintenance of banister of keeping off a car.
Utility model content
it is simple that the purpose of this utility model is to provide a kind of structure, the novel banister of keeping off a car that limit function is good.
For solving the problems of the technologies described above, the technical solution adopted in the utility model is as follows:
A kind of novel banister of keeping off a car, the pin comprising motor and be connected with motor, described motor is connected with electronic relay, and electronic relay is connected with travel switch.
The utility model uses travel switch spacing, and substitute in prior art electromagnetic induction stopping means in banister of keeping off a car spacing, good limit effect, simultaneously when keeping off a car banister frequent operation, not easily occurs the situation of spacing inefficacy.
Preferably, described electronic relay is connected with A.C. contactor, and A.C. contactor is connected with motor.
Accompanying drawing explanation
fig. 1 is structural representation of the present utility model.
Detailed description of the invention
Below in conjunction with accompanying drawing, the utility model is described in further detail.
As shown in Figure 1, a kind of novel banister of keeping off a car, the pin 4 comprising motor 1 and be connected with motor 1, motor 1 is connected with A.C. contactor 5, and A.C. contactor 5 is connected with electronic relay 2, and electronic relay 2 is connected with travel switch 3.Described A.C. contactor 5 is CJ20 A.C. contactor.
During work, motor 1 drives pin 4 to rotate, and when pin 4 is parallel to the ground, travel switch 3 controls electronic relay 2 and disconnects, and then controls electric motor circuit breaking, pin 4 stop motion; When travel switch 3 lost efficacy, because motor 1 continues power supply, pin 4 continues to fall, and current capacity is comparatively large, and A.C. contactor 5 disconnects, circuit breaker in whole banister of keeping off a car, the safety of protection circuit plate.
