Detailed Description

The utility model is further illustrated by the following figures and examples, which are not intended to be limiting.

Example 1. A driving suction cup alarm device is shown in fig. 1, and comprises three alarm lamps 1, wherein the three alarm lamps 1 are connected in parallel with a quick connector, and the three alarm lamps 1 are respectively positioned on the front side and the left side and the right side of a driving cab of a driving vehicle. The alarm lamp 1 is a rotary alarm lamp.

When the quick connector is still electrified, the alarm lamp 1 is electrified, and the alarm lamp 1 is lightened; when the quick connector is not electrified, the alarm lamp 1 is not electrified to be extinguished. The driver can know whether the power off of the sucker is finished or not by observing the on-off of the alarm lamp 1, so that misoperation of an inspection maintainer is avoided. Because the sucking disc only moves around the front side of the cab, through all setting up alarm lamp 1 in the front side and the left and right sides of the cab, can make the sucking disc no matter what position in the workshop stays, the maintainer can both observe one of them relatively easily, knows the break-make state of sucking disc easily, and three alarm lamps 1 can not all be blocked by the cab. In example 1, the warning lamp 1 was turned on, the quick connector was charged, and when it was not turned on, the quick connector was not charged. In example 1, the bulb in the warning lamp 1 was connected in parallel with the quick connector.

Example 2. The utility model provides a driving sucking disc alarm device, as shown in fig. 1 and 2, includes three alarm lamp 1, and three alarm lamp 1 are located the front side and the left and right sides of the driver's cabin of driving respectively.

Be equipped with shell 2 on the base of alarm lamp 1, be equipped with solenoid 3 in the shell 2, solenoid 3 connects parallelly connected quick-operation joint, is equipped with columnar iron core 6 in the solenoid 3, iron core 6 and solenoid 3 clearance fit, and the below of iron core 6 is equipped with first contact 8 and second contact 9, and first contact 8 and second contact 9 are all fixed with shell 2, and two electric terminals of alarm lamp 1 are connected respectively to first contact 8 and second contact 9. The first contact 8 and the second contact 9 are spring ejector pins.

The alarm lamp 1 can be obtained by direct purchase, such as JY-1101SJ type, is connected with a mains supply for supplying power, and removes a switch on the original alarm lamp, namely two power receiving ends on the alarm lamp 1 are formed. The two electric terminals are originally connected to the switch, and when the switch is pressed down and the circuit is conducted (namely, when the two electric terminals are electrically connected), the original alarm lamp emits light, otherwise, the original alarm lamp does not emit light.

Working principle: when the quick connector is still electrified, the electromagnetic coil 3 is correspondingly electrified to generate a magnetic field, so that the iron core 6 is kept high, at the moment, the two electric connection ends are not electrically connected, and the alarm lamp 1 cannot be lightened. When the quick connector is not electrified, the electromagnetic coil 3 is not electrified, the iron core 6 descends to a height under the action of gravity, the first contact 8 is electrically connected with the second contact 9 through the iron core 6, and the alarm lamp 1 emits light. In example 2, the warning lamp 1 was turned on, and the quick connector was not charged, and when it was not turned on, the quick connector was charged, contrary to example 1. In example 2, the electromagnetic coil 3 on the warning lamp 1 was connected in parallel with the quick connector.

Example 1 compares with example 2: embodiment 1 is simple in structure and low in cost, but the alarm lamp 1 itself fails without emitting light, and when the alarm lamp 1 fails, an error signal may be given to an inspector to complete the power-off work for the driver, and the quick connector is pulled down under the condition that the quick connector is still electrified, so that some potential safety hazards still exist. Embodiment 2's structure is more complicated, needs to repacking current alarm lamp 1, and the cost is higher relatively, and the advantage is, the alarm lamp only can light under the uncharged condition of quick-operation joint, even the alarm lamp 1 trouble and can not light, the maintainer also can not blind pull out quick-operation joint, and the security is better.

The utility model discovers the technical problems existing in workshops in the production process of the applicant, and the corresponding improvement is obtained, so that the improvement range is not large, but good technical effects can be achieved, and the improvement cost is low.
