Abstract
The utility model discloses a new alarm device for dolly non-lockup which solves the problem that currently an alarm device is lacked on the joint between a tractor and a trailer which can not give an alarm when the two are not lockup and easy to cause an accident. The utility model has the advantages of simple structure, easy use and reminding a non-lockup state in time, etc. The structure of the utility model is: a lockup alarm switch is arranged on the baffle block of the dolly; a spring is arranged in the lockup alarm switch; the spring is contacted with an executing switch with a baffle plate; the lower part of the baffle plate of the executing switch is an electrical wire cuttage grafting component with one end inserting into the lockup alarm switch. The other end is connected with an alarm circuit.
Description
Technical field
The utility model is a not locking warning device of a kind of novel traction seat, belongs to vehicle ancillary service technical field.
Background technology
Tractor mainly links to each other by traction seat with trailer at present, owing to have only a tie point.If the trailer towing pin is not by complete locking, and operating personnel do not notice, this just is easy to have an accident, so need not locking warning device of a kind of traction seat, remind the driver in time not handle under the situation of locking, to prevent the generation of accident at traction seat.
Summary of the invention
The purpose of this utility model is exactly in order to solve the deficiencies in the prior art, and the novel traction seat that a kind of simple in structure, economic and reliable is provided is the locking warning device not.
For achieving the above object, the utility model adopts following technical scheme:
A kind of novel traction seat is the locking warning device not, it has the locking alarm switch, be installed on the block of traction seat, establish spring in the described locking alarm switch, spring contacts with the execution switch of band baffle plate, the baffle plate below of carrying out switch is the electric wire plug connector that an end inserts the locking alarm switch, and its other end is connected with warning circuit.
Described electric wire plug connector and locking alarm switch splicing position are provided with electro-insulating rubber.
Described warning circuit is in parallel alarm lamp and alarm buzzer, the termination power after its parallel connection, the other end plug connector of connecting wires.
The utility model is made up of locking switch, alarm buzzer, alarm lamp.The locking switch is not under by the situation of complete locking, and by alarm lamp Chang Liang, the alarm buzzer buzzing reminds operating personnel to note; Fully indicator lamp goes out during locking, and buzzing stops.
The beneficial effects of the utility model are simple in structure, and are easy to use, can in time provide prompting to human pilot, avoid the generation of accident.
Description of drawings
The state of locking alarm switch when Fig. 1 a is the traction seat locking;
Fig. 1 b is the state of traction seat locking alarm switch when opening
Fig. 2 is traction seat locking alarm principle figure.
Among the figure, 1, traction seat, 2, the locking alarm switch, 3, block, 4, carry out switch, 5, electric wire plug connector 6, alarm lamp, 7, alarm buzzer, 8, spring, 9, electro-insulating rubber.
The specific embodiment
The utility model is described in further detail below in conjunction with accompanying drawing and embodiment:
When traction seat 1 is opened or fully during locking (shown in Fig. 1 b), block 3 in the traction seat 1 segment distance that all will move up, the execution switch 4 that is fixed on this moment in the locking alarm switch 2 on the block 3 separates with traction seat 1, spring 8 will extend owing to losing the external force effect, to carry out switch 4 and contact bonding with electric wire plug connector 5, alarm lamp the last 6 that this moment, circuit was connected in the driver's cabin is bright, buzzing when alarm buzzer 7 leaves simultaneously, remind the driver to note, as shown in Figure 2.When traction seat 1 locking as shown in Figure 1a, block 3 moves down, carrying out switch 4 contacts with traction seat, and compression spring 8 moves up, carry out switch 4 and separate, owing to electric wire plug connector 5 is separated by electro-insulating rubber 9 and metal shell, so circuit can not bonding with electric wire plug connector 5, this moment, circuit interruption alarm lamp 6 quit work with alarm buzzer 7, and the complete locking of traction seat is described.
