Description
Technical Field
[0001] The utility model relates to the technical field of recreational vehicles, in particular to a fixed ladder for recreational vehicles. Background Art
[0002] RVs have a relatively compact structure. In order to expand the internal area of RVs as much as possible, various structures that can expand the RV compartments have emerged. As a result, how to climb from the ground to the top of the RV, how to conveniently inspect the air conditioner, skylight and other equipment on the top of the RV, and how to clean the dust on the top of the RV are all issues that technicians in this field need to consider.
[0003] In order to prevent children from climbing up at will and falling from a high place, most of the existing fixed ladders for RVs are foldable. If the foldable type is used, a support arm and a baffle must be installed at the lower half of the fixed ladder to lean against the vehicle surface to support the lower fixed ladder. However, most of the existing support arms are not retractable, resulting in different fixed ladders being manufactured for different vehicle models, which is very inconvenient. In addition, most of the existing support arms are connected to the connecting rods with bolts and threaded holes, and the installation and disassembly of the support arms are relatively complicated. Utility Model Content
[0004] In view of the problems in the prior art, the utility model provides a fixed ladder for a recreational vehicle.
[0005] The technical solution adopted by the utility model to solve its technical problems is a fixed ladder for a motorhome, including a first connecting rod, a support arm, a clamping head, a connecting piece and a movable plate. The first connecting rod is in two groups, and the tops of the two groups of the first connecting rods are fixedly connected by a U-shaped seat. The bottom ends of the two groups of the first connecting rods are hinged to the top ends of the second connecting rods. One side of the two groups of the second connecting rods is provided with a clamping device, and the two groups of the clamping devices include a first positioning piece and a second positioning piece. The second positioning piece is provided with a clamping groove, and both sides of the second positioning piece are fixedly connected to the mounting plate, one side of the first positioning piece is fixedly connected to the clamping piece, and both sides of the first positioning piece are fixedly connected to the mounting plate.
[0006] By adopting the above technical solution, in daily use, RV owners seldom use the fixed ladder, so the fixed ladder is mostly in a folded state at ordinary times. For this reason, there is no need to use the support arm and the baffle, so a snap device is provided. The snap device facilitates the fixation and disassembly of the support arm. The installation of the support arm can be completed by simply inserting the snap piece on the first positioning piece connected to the support arm into the slot of the second positioning piece connected to the second connecting rod. The disassembly can be completed by pulling the snap piece out of the slot. When the support arm and the baffle are not used daily, they can be directly stored in the car to prevent wind and sun exposure and extend the service life.
[0007] Specifically, the mounting plate is provided with third threaded holes through the top and the bottom, and the third threaded holes are in two groups and are respectively distributed on both sides of the mounting plate. The third threaded holes cooperate with screws to detachably connect the first positioning piece to the support arm, and the third threaded holes cooperate with screws to detachably connect the second positioning piece to the second connecting rod.
[0008] By adopting the above technical solution, the buckle device is stably installed on the support arm and the second connecting rod through the screw and the third threaded hole.
[0009] Specifically, there are two groups of arms and they are distributed on both sides of the two groups of second connecting rods. The two groups of arms are hollow arms with an opening on one side. There are two groups of movable plates and they are respectively distributed inside the two groups of arms. Second threaded holes are opened on the tops of the two groups of movable plates. There are several groups of second threaded holes. The second threaded holes cooperate with second bolts to detachably connect the movable plates to the arms. One side of the two groups of movable plates is jointly fixedly connected to a baffle, and the outer surface of the baffle is fixedly connected to a sponge.
[0010] By adopting the above technical solution, by opening a plurality of groups of second threaded holes on the top of the movable plate, the length of the movable plate outside the support arm can be adjusted to adapt to RVs of different sizes, so that the baffle can contact the vehicle body when the fixed ladder is unfolded, thereby supporting the lower half of the fixed ladder, and the sponge prevents the baffle from damaging the vehicle paint.
[0011] Specifically, two groups of pedals are fixedly connected to the inner walls of the first connecting rods, and two groups of pedals are fixedly connected to the inner walls of the second connecting rods. The number of pedals is several groups and is evenly distributed between the first connecting rods and the second connecting rods. The number of connecting pieces is several groups and is symmetrically distributed on both sides of the two groups of first connecting rods. The connecting pieces are I-shaped connecting pieces. First threaded holes are provided on the top and bottom of the connecting pieces. The number of the first threaded holes is four groups and is symmetrically distributed on the top and bottom of the connecting pieces. The first threaded holes cooperate with screws to detachably connect the first connecting rod to the vehicle body.
[0012] By adopting the above technical solution, the pedal can help people climb up in one step, making it safer for people to go up to the roof, and the connecting piece fixes the first connecting rod to the vehicle body through screws cooperating with the first threaded hole.
[0013] Specifically, the top of the pedal is fixedly connected to an anti-slip pad.
[0014] By adopting the above technical solution, the pedal is easily soaked with rainwater on rainy days, causing it to be very slippery. In order to prevent people from falling and causing injuries to the body, an anti-slip mat is provided at this position.
[0015] Specifically, both sides of the two groups of the first connecting rods are equipped with detachable connecting straps with clamps, and the straps are provided with connecting holes on both sides. The number of the connecting holes is three groups, and both sides of the two groups of the second connecting rods are provided with clamps.
[0016] By adopting the above technical solution, in the folded state, the clamping head passes through the connecting hole, and the binding belt fixes the lower half of the fixed ladder to the upper half.
[0017] Specifically, the material of the binding strap is fumed silica gel.
[0018] By adopting the above technical solution, the gas phase silica gel is more durable and less likely to break.
[0019] Beneficial effects of the utility model:
[0020] (1) The fixed ladder for a motorhome described in the utility model can be installed by simply inserting the clamp on the first positioning member connected to the support arm into the clamping groove of the second positioning member connected to the second connecting rod.
