Embodiment 1
[0015] exist figure 1 Among them, a folding step ladder for a caravan, which includes a fixed seat 1 and a first step 4 .
[0016] like figure 1 As shown, the fixing seat 1 is composed of a fixing beam 101 and two fixing plates 102 symmetrically welded on both sides of the fixing beam 101 . The fixed crossbeam 101 can be fixed on the vehicle frame by conventional welding methods, or can be fixedly connected to the vehicle frame by bolts by having mounting holes thereon. In order to facilitate assembly and disassembly, in this implementation, mounting holes are provided on the fixed cross beam, and then the fixed cross beam 101 is fastened on the vehicle frame with bolts.
[0017] like figure 1 As shown, on both sides of the first pedal 4 there are respectively symmetrically fixed first pedal frames 5 protruding outwards, and the distal end of each first pedal frame 5 is curved and upturned.
[0018] exist figure 1 Among them, a first arm 2 is rotatably connected between t...
Embodiment 2
[0023] like image 3 As shown, a step ladder for a folding caravan, compared with Embodiment 1, further includes a second step 8 .
[0024] like image 3 As shown, the two sides of the second pedal 8 are respectively symmetrically fixed with protruding second pedal frames 9 , and the distal end of each second pedal frame 9 is curved and upturned.
[0025] The extended end of the second support arm 3 is rotatably connected on the far end of the second pedal frame 9 on the same side, and is rotatably connected between the nearly curved part of the second pedal frame 9 on the same side and the middle part of the first pedal frame 5 a third arm 10, at image 3 Among them, the first pedal frame 5, the second arm 3, the second pedal frame 9, and the third arm 10 on the same side constitute a scalene four-bar mechanism, and the first pedal frame 5 and / or the second pedal frame 9 push and pull, the step ladder can be opened or retracted.
[0026] In order to achieve the purpose of...

Abstract
The invention discloses a folding motor home tread plate ladder. The problem that existing fixed motor home tread plate ladders occupy internal space of motor homes is mainly solved. The folding motor home tread plate ladder comprises a fixing base and a first tread plate. The folding motor home tread plate ladder is characterized in that the fixing base is composed of a fixing transverse beam and two fixing plates symmetrically connected to the two sides of the fixing transverse beam; first tread plate frames are symmetrically fixed to the two sides of the first tread plate respectively; the far end of each first tread plate frame is bent and warped upwards; first supporting arms are arranged between the fixing plates and the far ends of the corresponding first tread plate frames which are arranged on the same side with the fixing plates; second supporting arms are arranged between the fixing plates and the positions near bent parts of the corresponding first tread plate frames which are arranged on the same side with the fixing plates; first positioning grooves are formed in the second supporting arms; the lower ends of the first supporting arms are locked in the first positioning grooves when the first tread plate is opened to the extreme position; tension springs used for locking the first tread plate are arranged between the fixing plates and the positions near the lower ends of the corresponding first supporting arms which are arranged on the same side with the fixing plates. The folding motor home tread plate ladder is simple in structure, reliable to use, convenient to operate and small in occupied space.
Description
technical field [0001] The invention relates to a ladder installed on a vehicle, in particular to a foldable pedal ladder for a caravan. Background technique [0002] We know that the door of the RV is a certain distance from the ground. Therefore, as a convenient tool for getting on and off the car, the step ladder is an essential part of the RV. At present, the pedal ladder of the RV is generally fixed, and its main pedal is composed of connecting plates located on both sides of the pedal. Shock, prolong service life. At the same time, in order to achieve the purpose of compacting the car body, the step ladder is usually sunk and fixed inside the car body, and the step ladder with this structure occupies the interior space of the caravan. Contents of the invention [0003] In order to overcome the shortage of existing fixed step ladders for caravans occupying the interior space of the caravan, the present invention provides a foldable step ladder for caravans with simp...
