Description

The coordinated type foot pedal structure of used in fire-fighting

Technical field

The utility model belongs to the fire fighting equipment technical field, is specifically related to a kind of coordinated type foot pedal structure of used in fire-fighting, is configured on the fire extinguishing tanker and corresponding to fire extinguishing tanker trailing wheel position, for the fire fighter provides step, so that pick and place fire fighting apparatus and materials to the equipment railway carriage or compartment.

Background technology

China utility model patent Granted publication CN201140691Y recommends to have a kind of linkage wood clapper structure, this patent scheme has remedied in the prior art and the existing shortcoming of linkage wood clapper structure that put to the proof in this background technology hurdle, specifically can be referring to the 1st page of the 7th to 19 row of specification sheets of this patent.The technical spirit of this patent scheme is to have adopted two groups of STATEMENT OF FEDERALLY SPONSORED that constitute the four-bar linkage structure form each other, when unfolding or collect tread plate, need only and just can finish by fire fighter's once action, for reducing operation link, the save operation time has good achievement.But still have shortcoming,, by stop pin tread plate is implemented locking, and stop pin is arranged on the winding gate, when enabling, must give the unlatching winding gate earlier and just can make the stop pin release because when tread plate is in collecting state.Otherwise can't enable tread plate, the Instructions Page 3 of concrete visible this patent the reciprocal the 5th walks to the 6th page of eighth row.And because this patent scheme adopts two cover four-bar linkages, motion link complexity, action stability is difficult to guarantee, and makes and the assembling trouble.

The movable foot pedal device of the fire extinguishing tanker that Granted publication CN201350876Y provides can make tread plate be in the exhibition state in use, under non-working condition, be in hidden state, has positive effect for the whole clean and tidy effect of improving vehicle, but the drawback that has last patent equally, that is, in the time will enabling, need give the unlatching door earlier, expose operating handle and locking handle, otherwise the tread plate (patent claims pedal) that is in hidden state is put on display outside the car.In addition, the structure that this scheme is recommended also is not suitable for tread plate is concealed in the cavity at wheel place of fire extinguishing tanker, specifically can read the Instructions Page 3 final stage of this patent.

In view of the deficiency that above-mentioned prior art exists, the applicant has carried out practice lastingly and repeatedly, finds a way to resolve the problem finally, and technical scheme described below is based on producing under this prerequisite.
