Embodiment Construction

[0013] Referring to Fig. 2, a pair of wall plates 61 corresponding to the two sides of the rear wheel cavity 6 of the fire engine are provided, and the wall plates 61 are fixed on the bracket 611. It goes without saying that the space formed by the bracket 611 is Room for the rear wheels of the fire truck. The cylinder bodies of a pair of gas spring cylinders 1 are respectively connected to the upper parts of the two ends of the rear side of the bracket 611, and the cylinder posts 11 of a pair of gas spring cylinders 1 are respectively connected by pin shafts 111 to the first pins of the corresponding group of linkages 4. The front end of a connecting rod 41 is the upper end shown in the figure and is hingedly connected, and the rear end of the first connecting rod 41 is the lower end shown in the figure. hinged. In order to prevent any mutual interference between the first and second connecting rods 41, 42, a rotating shaft 411 is arranged at the front end of the first conne...

Abstract

The invention relates to a linkage mopboard structure, belonging to the technical field of fire fighting vehicle. The linkage mopboard structure comprises a pair of air spring cylinders, a tread plate, a protective plate and two groups of linkage pieces. Each group of linkage piece consists of a first connecting rod and a second connecting rod which are parallel with each other, wherein, the front end of the first connecting rod is articulated with the cylinder column of the air spring cylinder. The cylinder body of the air spring cylinder is connected with the frame of the wall board of the rear wheel cavity of the fire fighting vehicle. The back end of the first connecting rod is articulated with the lateral face of the tread plate. The front end of the second connecting rod is articulated with the wall board and the back end of the second connecting rod is articulated with the lateral face of the tread plate. The protective plate is arranged at a corresponding position at the bottom of the tread plate and is connected respectively with the tread plate and the first connecting rod. At least one pull-handle is arranged on the tread plate. The invention has the advantages that by adopting two groups of linkage pieces which form a four-connecting rods structure, so when being used, the tread plate can be unfolded out of the rear wheel cavity with the help of only one time of pulling action, and at the same time the invention can make the tread plate be in a level state, so that one time of time can be saved. The restoration of the tread plate after using can also be completed by only once action.

Description

technical field [0001] The invention belongs to the technical field of fire-fighting vehicles, and in particular relates to a linkage pedal structure, which is arranged on the fire-fighting vehicle and corresponds to the upper part of the rear wheel cavity, and provides steps for fire-fighters to facilitate the fire-fighters to pick and place equipment from the equipment compartment. Background technique [0002] The prior art is arranged on the side of the equipment compartment of the fire truck and corresponds to the linkage pedal structure at the rear wheel cavity, as shown in Figure 1, including a gas spring cylinder 1, a pedal 2, a guard plate 3, and a linkage 4 , spring cylinder 8, the cylinder block of gas spring cylinder 1 is connected on the wall plate 61 of rear wheel chamber 6, and its cylinder column 11 is connected with one end of linkage 4, and the other end of linkage 4 is connected with guard plate 3, step on One side of the plate 2 is hinged with the guard p...
