Based on the embodiments in the utility model, all other embodiments obtained by those skilled in the art without creative labor fall within the protection scope of the utility model.
[0028] As Figures 1-4 shown, the technical solutions adopted by the utility model are as follows:
[0029] A motor home parking stabilizing device, including support frame 1, the top of support frame 1 is rotationally connected with first threaded rod 3, and the bottom end of first threaded rod 3 is coaxially fixedly connected with first spline shaft 7. The top of support frame 1 is fixedly connected with motor 2, and motor 2 drives first threaded rod 3 to rotate. First threaded rod 3 drives first spline shaft 7 to rotate.
[0030] The first threaded rod 3 is sleeved with a first moving plate 4, and the top of the first moving plate 4 is provided with a top support. The rotation of the first threaded rod 3 drives the first moving plate 4 to move upwards or downwards, thereby driving the top support to move.
[0031] The top support comprises a top plate 15. The outer surface of the first moving plate 4 is in sliding fit with the inner wall of the support frame 1, and the outer surface of the first moving plate 4 is uniformly and fixedly connected with a plurality of protrusions. The inner wall of the support frame 1 is provided with grooves matched with the protrusions, and the protrusions are in sliding connection with the corresponding grooves. Through the cooperation of the protrusions and the grooves, the first moving plate 4 can only move up and down in the inside of the support frame 1.
[0032] The top of each protrusion is fixedly connected with a support rod 5, and the support rod 5 is in sliding connection with the corresponding groove. The top plate 15 is fixedly connected with the top of the plurality of support rods 5. The top end of the support rod 5 extends to the outside of the support frame 1, so that the top plate 15 moves above the support frame 1, so as to support the motor home through the top plate 15.
[0033] The bottom of the support frame 1 is rotatably connected with a second threaded rod 9, and the top end of the second threaded rod 9 is coaxially and fixedly connected with a second spline shaft 8. The second threaded rod 9 is sleeved with a second moving plate 10.
[0034] The outer surface of the second moving plate 10 is in sliding fit with the inner wall of the support frame 1, and the outer surface of the second moving plate 10 is uniformly and fixedly connected with three groups of connecting pieces. The side surface of the bottom of the support frame 1 is provided with sliding grooves matched with the connecting pieces, and the connecting pieces are in sliding connection with the corresponding sliding grooves. Through the cooperation of the connecting pieces and the sliding grooves, the second moving plate 10 can only move up and down in the inside of the support frame 1.
[0035] The connecting piece comprises two spaced-apart connecting plates 16, and the mutually away sides of the two connecting plates 16 are in sliding fit with the inner wall of the sliding groove. The connecting plate 16 can only move up and down along the sliding groove.
[0036] The bottom of the second moving plate 10 is provided with a bottom support.
[0037] The bottom support comprises three first connecting rods 12. The three first connecting rods 12 correspond to the three groups of connecting pieces one by one, and one end of the first connecting rod 12 is fixedly connected with a connecting shaft 11, and the connecting shaft 11 is rotatably connected between the corresponding two connecting plates 16.
[0038] One side of each first connecting rod 12 is rotatably connected with a second connecting rod 13, and the other end of the second connecting rod 13 is rotatably connected to the bottom surface of the corresponding sliding groove. The rotation of the first connecting rod 12 drives the second connecting rod 13 to rotate, and the stability of the first connecting rod 12 is increased through the second connecting rod 13.
[0039] Each first connecting rod 12 is rotatably connected with a hinged seat 14 away from one end of the connecting plate 16, and the end of each hinged seat 14 is fixedly connected with a bottom plate 17. The hinged seat 14 is used to facilitate the rotation of the bottom plate 17, so that the bottom plate 17 is in close contact with the ground, thereby increasing the stability of the support frame 1.
[0040] The bottom of the first moving plate 4 is rotatably connected with a spline sleeve 6, and the spline sleeve 6 movably sleeves the first spline shaft 7 and the second spline shaft 8. The spline sleeve 6 is used to connect the first spline shaft 7 and the second spline shaft 8, so that the first spline shaft 7 and the second spline shaft 8 rotate together.
[0041] The first spline shaft 7 and the second spline shaft 8 are coaxially arranged, and there is a spacing between the first spline shaft 7 and the second spline shaft 8. The first spline shaft 7 and the second spline shaft 8 are prevented from contacting each other, thereby affecting the stability of the second threaded rod 9. The chamfer is arranged at the clamping position of the bottom end of the spline sleeve 6 and the first spline shaft 7 and the second spline shaft 8, so that when the spline sleeve 6 moves downward, the spline sleeve 6 moves outward and is clamped to the first spline shaft 7 and the second spline shaft 8.
[0042] Working principle:
[0043] In use, the support frame 1 is moved to the bottom of the motor home. The bottom plate 17 is located on the ground, and the top plate 15 faces the motor home.
[0044] Start the motor 2, and the output shaft of the motor 2 rotates in the positive direction. The first threaded rod 3 is driven to rotate, the first moving plate 4 is driven to move upward, the spline sleeve 6 moves upward, and the support rod 5 and the top plate 15 move upward.
[0045] The first threaded rod 3 drives the first spline shaft 7 to rotate, the first spline shaft 7 drives the spline sleeve 6 to rotate, and the spline sleeve 6 drives the second spline shaft 8 to rotate, so that the spline sleeve 6 rotates while moving upward.
[0046] The second spline shaft 8 drives the second threaded rod 9 to rotate, and the second threaded rod 9 drives the second moving plate 10 to move downward, so that the connecting plate 16 moves downward.
[0047] The connecting plate 16 drives one end of the first connecting rod 12 to move. Since the other end of the second connecting rod 13 is positioned on the support frame 1, the second connecting rod 13 pushes the first connecting rod 12 to rotate, so that the three bottom plates 17 move away from each other.
[0048] As the spline sleeve 6 moves upward, the spline sleeve 6 will first move away from the second spline shaft 8. The second threaded rod 9 stops rotating, the first connecting rod 12 stops moving, and the support frame 1 is positioned on the ground at this time. Then, the spline sleeve 6 moves away from the first spline shaft 7, so that the spline sleeve 6 no longer rotates, until the top plate 15 abuts against the motor home, thereby supporting the motor home and achieving the purpose of stabilizing the motor home.
[0049] After the use is completed, the output shaft of the motor 2 is reversed. The first moving plate 4 and the spline sleeve 6 are moved downward, the bottom end of the spline sleeve 6 is first moved to the outside of the first spline shaft 7, the first spline shaft 7 is matched with the spline sleeve 6, and the spline sleeve 6 is rotated. The spline sleeve 6 continues to move downward to the outside of the second spline shaft 8, the second spline shaft 8 is rotated with the second threaded rod 9, the second threaded rod 9 drives the second moving plate 10 to move upward, the first connecting rod 12 is rotated, and the three bottom plates 17 are close to each other.
[0050] Although the utility model has been described in detail with reference to the foregoing embodiments, those skilled in the art can still modify the technical solutions recorded in the foregoing embodiments or make equivalent replacement to part of the technical features, and any modification, equivalent replacement, improvement, etc. made within the spirit and principle of the utility model should be included in the protection scope of the utility model.
