The existing boarding ladder has more structural components, so that the installation is very troublesome and laborious, the boarding ladder is generally integrally formed, or the boarding ladder is fixed on a vehicle, the automatic retraction and release cannot be realized, the manufacturing and production are not easy, the use is very inconvenient, the shaking is easy to occur, the injury is caused to the safety of personnel, and the applicability is poor.
SUMMERY OF THE UTILITY MODEL
An object of the utility model is to provide an automatic ladder of pedaling that receive and releases of interlock formula to it is more to provide current ladder structural component of pedaling in solving above-mentioned background art, makes the installation get up very trouble hard, is the fashioned ladder of pedaling of integral type generally, perhaps fixes on the car, can not realize automatic receiving and releasing, also difficult manufacturing production, and it is very inconvenient to use, takes place to rock easily, causes the injury to personnel's safety, the poor problem of suitability.
In order to achieve the above object, the utility model provides a following technical scheme: the linked automatic retractable pedaling ladder comprises a pedaling ladder pedal, wherein one end of the pedaling ladder pedal is fixed on a chassis longitudinal beam through a fixing frame and a rotary limiting shaft. One end of the rotary limiting shaft is rotatably connected with a pull arm, one end of the pull arm is fixedly connected with one end of a flexible shaft pull wire through a flexible shaft pull wire fixing rotary pin and a rotary shaft pull wire fixing frame, the other end of the flexible shaft pull wire is connected in a linear bearing slide rail in a sliding mode, the linear bearing slide rail is fixed on a rear coaming of the vehicle body, and the linear bearing slide rail is connected with a power source in a sliding mode through a pushing swing arm.
As an optimal technical scheme of the utility model, the fixed surface of pedaling the ladder footboard installs a plurality of rubber pad.
As an optimal technical scheme of the utility model, the power supply sets up in the bounding wall behind the automobile body.
Compared with the prior art, the beneficial effects of the utility model are that:
the utility model discloses can realize automatic function that receive and releases, satisfy personnel intensity of ascending a ladder and receive and release free requirement, simple structure, installation are simple and easy, automatic receive and release, use steady, make easily, the practicality is strong, safe and reliable to, it is more convenient to pedal the car at military police vehicle personnel rear, has played decisive action more rapidly, is applicable to the vehicle of various demands.
