[0034] See also Figures 1-9In an embodiment of the utility model, a locking mechanism for a caravan step comprises a main frame 1, a cover plate 2 is provided on the top of the main frame 1, and a bottom plate assembly 3 is slidably connected to the inside of the main frame 1; a self-locking component for self-locking the bottom plate assembly 3 is provided inside the bottom plate assembly 3; fixing components for fixing the cover plate 2 are provided on both sides of the main frame 1; mounting components for installing the main frame 1 are also provided on both sides of the main frame 1; a moving component for moving the bottom plate assembly 3 is provided inside the main frame 1, and the bottom plate assembly 3 can be self-locked by the provided self-locking component, and the cover plate 2 can be fixed by the provided fixing component, the main frame 1 can be easily installed by the provided mounting component, and the bottom plate assembly 3 can be extended by the provided moving component.

[0035] In one embodiment, Figure 2 、 Figure 3 and Figure 4 As shown, the self-locking component includes a fixed plate 4, the bottom of the fixed plate 4 is fixedly connected to the inside of the base plate assembly 3, the top of the fixed plate 4 is fixedly connected to a gasket 5, the upper and middle part of the gasket 5 is threadedly connected to a first screw 6, the first screw 6 is slidably connected to the first limiting groove 8 opened on the lock plate 7, the inside of the gasket 5 is fixedly connected to a movable column 9, the inside of the lock plate 7 is rotatably connected to the outer surface of the movable column 9, the lock plate 7 and the fixed plate 4 are both provided with a locking nut 10, and a first spring 11 is provided between the two locking nuts 10. The base plate assembly 3 is self-locked by the lock plate 7, and the lock plate 7 rotates when subjected to force. Since the first screw 6 is inside the first limiting groove 8, the lock plate 7 can only rotate to a certain extent, and the first spring 11 will cause it to rebound when no force is applied.

[0036] In one embodiment, Figure 1 and Figure 2 As shown, the fixing assembly includes a second limiting groove 12, which is opened on both sides of the main frame 1. A first bolt 13 is slidably connected inside the second limiting groove 12, and the first bolt 13 is threadedly connected to the first nut at one end away from the main frame 1. By rotating the first nut, the first bolt 13 can move in the second limiting groove 12, so that the cover plate 2 is easy to install or disassemble.

[0037] In one embodiment, Figure 1 and Figure 2As shown, the mounting assembly includes a support frame 14, which is movably abutted against both sides of the main frame 1. A third limiting groove is also provided on both sides of the main frame 1. A second bolt 15 is movably connected inside the third limiting groove. The second bolt 15 is movably connected to the middle and upper part of the support frame 14. The end of the second bolt 15 away from the main frame 1 is threadedly connected with a second nut. By rotating the second nut, the second bolt 15 can move in the third limiting groove, thereby adjusting the position of the support frame 14, and then rotating the second nut again to fix the support frame 14. Adjusting the position of the support frame 14 can make the main frame 1 adapt to different types of RVs.

[0038] In one embodiment, Figure 2 and Figure 4 As shown, the moving component includes a connecting bracket 16, which is fixedly connected to the inside of the base plate assembly 3. A compressed gas spring 17 is fixedly connected to the inner side of the main frame 1, and the other end of the compressed gas spring 17 is fixedly connected to one side of the connecting bracket 16. A fixing bracket 18 is fixedly connected to the inner side of the base plate assembly 3, and a second spring 19 is provided on the fixing bracket 18. By applying a thrust to the base plate assembly 3, the compressed gas spring 17 rebounds after being subjected to the force, and the second spring 19 assists it, so that the base plate assembly 3 can rebound and extend.

[0039] In one embodiment, Figure 3 As shown, the locking plate 7 is in a fishhook shape, which facilitates the self-locking of the locking plate 7.

[0040] In one embodiment, Figure 2 and Figure 4 As shown, a second screw rod 20 corresponding to the notch of the locking plate 7 is provided inside the main frame 1 so that the locking plate 7 can hook the second screw rod 20 for locking.

[0041] In one embodiment, Figure 1 、 Figure 2 and Figure 4 As shown, dust covers are provided on both sides of the main frame 1 near the bottom plate assembly 3 to prevent dust from following the bottom plate assembly 3 into the interior of the main frame 1 .

[0042] The working principle of the present utility model is as follows: the above embodiment discloses a locking mechanism for RV steps, wherein according to different types of RVs, by rotating the second nut, the second bolt 15 can move in the third limiting groove, thereby adjusting the position of the support frame 14, and then rotating the second nut again to fix the support frame 14, and then fixing the main frame 1 to the required position of the RV through the support frame 14, and then by rotating the first nut, the first bolt 13 can move in the second limiting groove 12, so that the cover plate 2 can be installed, and then a thrust is applied to the bottom plate assembly 3 to drive the lock plate 7 to move, so that the lock plate 7 can be installed. The plate 7 hooks the second screw 20 and can apply thrust to it again, so that under the action of the compressed gas spring 17, the lock plate 7 disengages from the second screw 20 to achieve a rebound effect. Specifically, when the step is in state A (the bottom assembly 3 is extended), the bottom assembly 3 is pushed by hand. When it is in state B, under the action of the second screw 20, the lock plate 7 rotates clockwise and continues to push. When the lock plate 7 is in state C, the pushing is stopped. Under the action of the compressed gas spring 17, the bottom assembly 3 retreats. At this time, the lock plate 7 hooks the second screw 20, and the bottom plate assembly 3 stops moving. From state A-B-C, the retraction of the bottom assembly is completed. When the step is in state C (bottom plate assembly 3 retracted), the hand pushes the bottom plate assembly 3. Under the action of the second screw 20, after the lock plate 7 is in state D, the pushing is stopped. Under the action of the compressed gas spring 17, the bottom plate assembly 3 retreats to state E. Under the action of the compressed gas spring 17, it is finally in state A. From state C-D-E-A, the extension of the bottom plate assembly 3 is completed.

[0043] The above description is merely a specific embodiment of the present disclosure, but the scope of protection of the present disclosure is not limited thereto. Any changes or substitutions that can be easily conceived by a person skilled in the art within the technical scope disclosed in this disclosure should be included in the scope of protection of the present disclosure. Therefore, the scope of protection of the present disclosure should be based on the scope of protection of the claims.
