Description

Technical Field

[0001] The utility model relates to the field of recreational vehicles, and in particular to a lifting table for recreational vehicles. Background Art

[0002] A Chinese patent with publication number CN213882186U discloses a lifting table for RVs, comprising a table top and a lifting base arranged on the lower surface of the table top. The table top comprises a fixed plate arranged on the top of the lifting base and a telescopic plate movably connected to both sides of the fixed plate. The lifting base comprises a telescopic sleeve arranged on the lower surface of the fixed plate for supporting the fixed plate. The telescopic sleeve comprises an upper tube and a lower tube. The lower tube is provided with several adjustment holes, and the adjustment holes telescope and fix the upper tube through fixing bolts.

[0003] The above structure fixes the upper tube sleeved in the lower tube by screwing the fixing bolt into the adjustment hole, thereby achieving adjustment of the height of the table top. However, when the height of the table top needs to be adjusted, it is necessary to first loosen the fixing bolt on the lower tube on one side with a tool, and then loosen the fixing bolt on the lower tube on the other side. While loosening the fixing bolt on the lower tube on the other side, it is also necessary to hold the lower surface of the table top by hand to prevent the upper tubes on both sides from losing the limit of the fixing bolts and directly sliding down due to gravity. Finally, it is necessary to tighten the fixing bolt on one side while holding the table top to limit the height of the table top, and finally tighten the fixing bolt on the other side to complete the adjustment of the height of the table top, resulting in the overall process of adjusting the height of the table top being more complicated and laborious. Utility Model Content

[0004] In view of the shortcomings of the prior art in that the overall process of adjusting the height of the table board is relatively complicated and laborious, the utility model provides a lifting table for RVs that is convenient and labor-saving in adjusting the height of the table board.

[0005] In order to solve the above technical problems, the present invention is solved by the following technical solutions:

[0006] A lifting table for a recreational vehicle comprises a table top and table legs symmetrically arranged on both sides of the bottom surface of the table top, the table legs comprising a movable table leg whose top is fixed to the table top and a fixed table leg partially sleeved on the outside of the movable table leg, a length adjustment component for adjusting the overall length of the table leg is provided between the movable table leg and the fixed table leg, the length adjustment component comprising a vacuum suction cup symmetrically arranged on the outer wall of the end of the movable table leg away from the table top, which can be fitted with and adsorbed on the inner wall of the fixed table leg, and a control component for controlling the negative pressure of the vacuum suction cup to adsorb on the inner wall of the fixed table leg or to release the negative pressure state of the vacuum suction cup.

[0007] By adopting the above scheme, the vacuum suction cups symmetrically arranged on the outer wall of the movable table leg can be adsorbed on the inner wall of the fixed table leg under the control of the control component, thereby achieving the fixation between the movable table leg and the fixed table leg. When the overall length of the table leg needs to be adjusted, the vacuum suction cups can be controlled by the control component to release the negative pressure state. At this time, the movable table leg can move inside the fixed table leg. When the movable table leg finishes moving, the vacuum suction cups can be controlled by the control component again to be in a negative pressure state and adsorbed on the inner wall of the fixed table leg, thereby achieving the adjustment of the overall length of the table board and the adjustment of the height of the table board, making the height adjustment of the table board more convenient and labor-saving.

[0008] Preferably, the control component includes an air suction groove vertically arranged on the movable table leg, a sliding groove arranged on the bottom surface of the table top and connected with the air suction groove, an air suction hole arranged in the middle of the vacuum suction cup and connected with the air suction groove, and an air suction block that is partially slidably arranged in the sliding groove and adjusts the air pressure in the air suction groove and the suction cup hole as it slides in the sliding groove. A limiting component is provided on the bottom surface of the table top for limiting the movement of the air suction block when the air suction block controls the vacuum suction cup to be in a negative pressure state. A sealing component for increasing the sealing performance between the air suction block and the air suction groove is provided at one end of the air suction block close to the bottom of the air suction groove.

[0009] By adopting the above scheme, the suction block can slide in the sliding groove, and the sealing component arranged on the suction block can improve the sealing performance of the suction block when sliding in the sliding groove. When the suction block moves in the direction away from the movable table leg, the suction block will suck the air in the vacuum suction cup into the suction groove through the suction hole, so that the vacuum suction cup is in a negative pressure state and pressed against the inner wall of the fixed table leg, thereby achieving fixation between the fixed table leg and the movable table leg, and the limiting component can limit the position of the limiting block, so that the vacuum suction remains in a negative pressure state, and setting the sliding groove on the bottom surface of the table board makes it easier for the operator to hold the table board with both hands to drive the suction block to move, thereby making it more convenient to adjust the overall length of the table leg.

[0010] Preferably, the limiting component includes a limiting groove provided on the bottom surface of the table top away from the table legs and an elastic hook provided on the end of the suction block away from the insertion end and capable of being elastically engaged in the limiting groove.

[0011] By adopting the above scheme, the elastic hook arranged on the end of the suction block away from the insertion end can be elastically connected to the limiting groove on the bottom surface of the table board when the suction block drives the vacuum suction cup to a negative pressure state, thereby limiting the position of the suction block after movement, so that the vacuum suction cup remains in a negative pressure state, and the movable table leg and the fixed table leg are fixed.

[0012] Preferably, the sealing component includes a sealing block provided at the insertion end of the suction block.

[0013] By adopting the above solution, the sealing block provided can improve the sealing performance between the suction block and the sliding groove, so that the vacuum suction cup can be more firmly adsorbed on the inner wall of the fixed table leg.

[0014] Preferably, a blocking component for preventing the suction block from being completely inserted into the sliding groove is provided between an end of the suction block away from the insertion end and the bottom surface of the table top.

[0015] Preferably, the blocking component includes a blocking block with a width greater than the width of the sliding groove arranged at the end of the suction block away from the insertion end, and an avoidance space arranged on the bottom surface of the table top for avoidance when the blocking block moves, and the limit groove is arranged in the avoidance space.

[0016] By adopting the above scheme, the blocking block arranged on the suction block can block the movement of the suction block when the suction block moves into the sliding groove, thereby preventing the suction block from being fully inserted into the sliding groove, and the avoidance space set can avoid the sliding of the blocking block when the suction block moves in the direction away from the movable table leg.

[0017] Preferably, a pushing component is provided between the movable table leg and the vacuum suction cup to drive the vacuum suction cup to always maintain a state of being in contact with the inner wall of the fixed table leg.

[0018] Preferably, the pushing component includes a slot arranged at the movable table leg near the vacuum suction cup, a plug-in block partially sealed and inserted in the slot, and a spring whose two ends are respectively connected to the outer wall of the movable table leg at one end of the plug-in block away from the movable table leg and the length is greater than the distance from the outer wall of the movable table leg to the end of the plug-in block away from the movable table leg, and the plug-in block is arranged at the end of the plug-in block away from the movable table leg.

[0019] By adopting the above scheme, the provided spring can push the plug-in block to move, so that the vacuum suction cup provided at the end of the plug-in block remains in contact with the fixed table leg during use, and the length of the spring is set to be greater than the distance from the movable table leg to the end of the plug-in block away from the movable table leg, so that the spring is in a compressed state when the movable table leg is inserted into the fixed table leg. At this time, the spring can push the vacuum suction cup to remain in contact with the inner wall of the fixed table leg.

[0020] Due to the adoption of the above technical scheme, the utility model has significant technical effects: the vacuum suction cups symmetrically arranged on the outer walls of the movable table legs can be adsorbed on the inner walls of the fixed table legs under the control of the control component, thereby achieving fixation between the movable table legs and the fixed table legs; when the overall length of the table legs needs to be adjusted, the vacuum suction cups can be first controlled by the control component to release the negative pressure state, and the movable table legs can now move inside the fixed table legs; and when the movable table legs finish moving, the vacuum suction cups can be controlled by the control component again to be in a negative pressure state and adsorbed on the inner walls of the fixed table legs, thereby achieving adjustment of the overall length of the table board and adjustment of the height of the table board, making the height adjustment of the table board more convenient and labor-saving.
