[0026] The utility model discloses an outdoor ladder for a recreational vehicle, which is mainly used in recreational vehicle scenarios.

[0027] Reference Figure 1 and Figure 2, an outdoor ladder for a motorhome, comprising: a motorhome 1, a mounting plate 2 is equidistantly arranged on one side of the motorhome 1, two connecting blocks 3 are fixedly connected to one side of the mounting plate 2, a first ladder 4 is rotatably connected between one side of the two connecting blocks 3, a first connecting rod 6 is equidistantly fixedly connected to one side of the first ladder 4, a receiving groove 12 is provided inside the first ladder 4, a through groove 13 is provided on one side of the first ladder 4, a second ladder 5 is slidably connected inside the receiving groove 12, a second connecting rod 7 is fixedly connected between one side of the second ladder 5, the outer side of the second connecting rod 7 is slidably connected to the inside of the through groove 13, a supporting assembly is arranged at the bottom of the second ladder 5, a positioning assembly is arranged between one side of the first ladder 4 and the second ladder 5, and a fixing assembly is equidistantly arranged on one side of the motorhome 1, and the fixing assembly is used to fix the first ladder 4.

[0028] In the above technical scheme, the problem that the ladder may shake during the driving of the RV 1 is taken into consideration. In order to solve such problem, the specific operations are as follows: the second ladder 5 is put into the first ladder 4, the second ladder 5 is fixed by the positioning assembly, and the first ladder 4 is clamped and fixed by the fixing assembly, so that the first ladder 4 and the second ladder 5 are fixed to one side of the RV 1, which can ensure that the ladder will not shake or fall off during driving, and both the ladder and the RV 1 are protected, thereby improving driving safety and avoiding accidents. By setting a support assembly, the ladder can be prevented from accidentally moving during use, which can improve safety, reduce the risk of falling or sliding, and protect the safety of the user.

[0029] Reference Figure 2 and Figure 5 In a preferred embodiment, the fixing assembly includes a fixing block 8, which is equidistantly fixed on one side of the RV 1, and the internal thread of the fixing block 8 is connected to a rotating rod 15, one end of the rotating rod 15 extends to the outside of the fixing block 8 and is rotatably connected to a clamping block 16, and the inside of the clamping block 16 conflicts with the outside of the first ladder 4. The fixing assembly also includes two sliding rods 17, both of which are fixedly connected to one side of the clamping block 16, one end of the sliding rod 17 extends to one side of the fixing block 8 and is fixedly connected to a limiting block 18, the outside of the sliding rod 17 is slidably connected to the inside of the fixing block 8, and the outside of the sliding rod 17 is provided with a spring 19;

[0030] In the above technical scheme, the problem of ladder shaking is taken into consideration. In order to solve such problem, the specific operation is as follows: when the first ladder 4 and the second ladder 5 are folded up, the rotating rod 15 is rotated by hand, and under the action of the sliding rod 17, the block 16 moves horizontally and approaches the first ladder 4, so that the block 16 clamps and fixes the first ladder 4 from both sides. By setting the spring 19, the block 16 can always keep in contact with the first ladder 4, thereby preventing the block 16 from loosening during the driving of the RV 1.

[0031] Reference Figure 3 and Figure 4 In a preferred embodiment, the positioning component includes a groove 10, the grooves 10 are equidistantly formed on both sides of the second ladder 5, and a bolt 11 is threadedly connected to one side of the first ladder 4, and the outside of the bolt 11 is threadedly connected to the inside of the groove 10;

[0032] In the above technical solution, considering the problem that the second ladder 5 needs to be fixed when it extends and is in use, to solve such problems, the specific operation is as follows: by screwing the bolt 11 into the groove 10, the second ladder 5 is fixed to the first ladder 4, so that the ladder is safer to use.

[0033] Refer to Figure 3 and Figure 6 In a preferred embodiment, the support component includes a mounting groove 20, the mounting groove 20 is formed at the bottom of the second ladder 5, a first mounting rod 21 is rotatably connected to the inside of the mounting groove 20, a gear 22 is arranged on the outside of the first mounting rod 21, and a threaded rod 9 is threadedly connected to one side of the second ladder 5, and one end of the threaded rod 9 abuts against the outside of the gear 22. A connecting plate 23 is equidistantly and fixedly connected to the outside of the first mounting rod 21, a second mounting rod 24 is rotatably connected to the inside of the connecting plate 23, and a base 14 is arranged on the outside of the second mounting rod 24; by using the first mounting rod 21, the connecting plate 23 and the second mounting rod 24, the angle of the base 14 can be adjusted to make it support more stably. By using the threaded rod 9 and the gear 22, the first mounting rod 21 can be restricted to prevent the base 14 from rotating during use and affecting the support effect on the ladder.

[0034] Refer to Figure 2 and Figure 5 In a preferred embodiment, the block 16 is set in a U-shape, and a rubber pad is arranged inside the block 16; by adopting the U-shaped block 16, the first ladder 4 can be fixed from multiple faces, which can provide a larger support area and increase the contact area between the block 16 and the first ladder 4, thereby improving the fixing effect of the device. The rubber pad has good elasticity and buffering performance, and at the same time has friction. It can not only improve the fixing effect of the block 16, but also play a shock-absorbing role between the block 16 and the first ladder 4, reduce the influence of vibration and bumps on the first ladder 4 and the block 16, and extend the service life of the first ladder 4 and the block 16.

[0035] Working principle: When the ladder is needed, first turn the rotating rod 15 by hand to make the block 16 completely disengage from the first ladder 4, then turn the bolt 11 to disengage from the groove 10, and then take out the second ladder 5 for extension, and put the base 14 on the ground, adjust the ladder as a whole to a suitable angle, and then turn the threaded rod 9 so that one end of the threaded rod 9 contacts the notch of the gear 22, so that the base 14 will not rotate, and use the bolt 11 again to fix the first ladder 4 and the second ladder 5, and the ladder placement work is completed, and then When the ladder is used and needs to be put away, first rotate the threaded rod 9 to disengage it from the gear 22, then rotate the bolt 11 to disengage it from the groove 10, then put the second ladder 5 into the first ladder 4, reuse the bolt 11 to fix the first ladder 4 and the second ladder 5, then place the ladder vertically, and then rotate the rotating rod 15 to drive the clamping block 16 to move, so that the clamping block 16 clamps and fixes the first ladder 4 again, and the ladder can be fixed to one side of the RV 1. The contents not described in detail in this specification belong to the existing technology known to professional and technical personnel in this field.

[0036] The above is only a preferred specific implementation of the utility model, but the protection scope of the utility model is not limited to this. The replacement can be a replacement of part of the structure, device, method step, or a complete technical solution. Equivalent replacement or change based on the technical solution of the utility model and its utility model concept should be included in the protection scope of the utility model.
