Abstract
An automobile overload alarm is characterized in that the alarm is provided with a travel switch arranged between an automobile chassis and an automobile rear axle. The travel switch is provided with a casing, a movable contact block is arranged in the casing, a flexible rope is connected to the movable contact block, the lower end of the flexible rope is connected with the automobile rear axle, the lower end of the movable contact block is provided with a spring, and the lower end of the spring is pressed against the casing of the travel switch. The static contact block of the travel switch is fixed on the bottom of the automobile chassis and is connected with an alarm bell. When the automobile is loaded with cargos, the automobile steel plate spring is pressed, the automobile chassis is lowered, the flexible rope is loosened, the pull force applied on the movable contact block is released, and the movable contact block approaches the static contact block under the action of the spring. When the loading mass reaches rated automobile loading mass, the movable contact block and the static contact block of the travel switch are closed, and the alarm bell sends out alarm signals. The utility model has the advantages of simple structure, high reliability, easy installation and maintenance and easy popularization and use.
Description
Technical field
The utility model relates to the vehicular spare parts technical field, especially a kind of automobile overload annunciator.
Background technology
Present automobile especially is not equipped with the automobile overload annunciator on the goods carrying vehicle mostly, therefore the accidents such as vehicle rollover that cause owing to overload happen occasionally, for head it off, some vehicular spare parts manufacturers also develop some automobile overload annunciators, but the parts of these devices are many, and structure is more complicated all, sensitivity is low, damage easily, installation and maintenance are all cumbersome, are difficult to promote.
Summary of the invention
The purpose of this utility model just provides a kind of simple in structure, long service life, and installation and maintenance are easy to the automobile overload annunciator.
Solution of the present utility model is such: have the travel switch that is installed between automobile chassis frame and the automobile axle, the trip switch has housing, the movable contact piece is installed in housing, on described movable contact piece, be connected with flexible rope, the lower end of this flexible rope is connected with automobile axle, lower end at described movable contact piece is provided with spring, the housing of described travel switch is withstood in the lower end of this spring, the stationary contact piece of described travel switch is fixed on the bottom of automobile chassis frame and is connected with warning device, during the lorry loading goods, the automobile leaf spring pressurized, automobile chassis frame descends, flexible rope is lax, releasing is to movable contact piece pulling force, and the movable contact piece is close to the stationary contact piece under the effect of spring, when reaching the specified charge material amount of automobile when loading mass, the movable contact piece of travel switch and stationary contact piece closure, electric bell sends signal alarm.
In such scheme, the lower end of described flexible rope can be connected with the counterweight that a middle part is provided with blind hole, is connected with to adapt with described blind hole size and extend upwardly adjustable bracket to described blind hole opening part on described automobile axle.
The utility model has the advantages that:
Simple in structure, the reliability height, installation and maintenance are easy, and travel switch controlled by tightrope, can avoid being easier to promote the use of because of the automobile bumpiness damage alarming device.
Description of drawings
Accompanying drawing is embodiment of the present utility model.
Accompanying drawing 1 is a structural representation of the present utility model.
Accompanying drawing 2 is electric control theory figure of the present utility model.
The specific embodiment
Embodiment of the present utility model includes automobile chassis frame 1, stationary contact piece 2, housing 3, movable contact piece 4, spring 5, rope 6, counterweight 7, adjustable bracket 8, automobile axle 9.
In structure shown in Figure 1, the utility model has the one stroke switch, this travel switch has a housing 3, the upper end of stationary contact piece 2 closure casings 3 of travel switch also is communicated with the bottom that housing 3 is fixed on automobile chassis frame 1 together, stationary contact piece 2 is connected with warning device, what in the present embodiment, warning device adopted is electric bell.In the inside of housing 3 movable contact piece 4 is installed, is provided with spring 5 in the lower end of movable contact piece 4, the lower end of this spring 5 withstands on the bottom interior wall of housing 3.On the movable contact piece, stretch out the rope 6 that connecting rod outside the housing is connected with a flexibility by one, the lower end of rope 6 is mounted with a counterweight 7, have a blind hole at the middle part of counterweight 7, on automobile axle 9, be provided with one and adapt with the blind hole size and extend upwardly adjustable bracket 8 to described blind hole opening part.In electrical schematic diagram shown in Figure 2, the energising of travel switch K1 and electric bell D1 is closing and whether determine that hand switch is arranged in the operator's compartment by hand switch L1 whether.
After the utility model was installed, automobile was when preparing loading, and the driver connects the hand switch K1 that is contained in the operator's compartment.In the lade process, the automobile leaf spring pressurized, automobile chassis frame descends, and when loading mass reached the specified charge material amount of automobile, adjustable bracket stretched to the top of counterweight blind hole and holds counterweight, flexible rope is lax, releasing is to movable contact piece pulling force, the movable contact piece under the effect of spring to the stationary contact piece near close and, the electric wiring energising, electric bell sends signal, stops the operation of freighting.The driver control hand switch was cut off the electricity supply after loading finished.
