Description

Technical Field

[0001] The utility model belongs to the technical field of lifting tables, and particularly relates to an electric lifting table which is easy to lift. Background Technique

[0002] A lifting table is a table whose desktop height can be adjusted, and generally consists of components such as telescopic table legs, a tabletop, a frame, and a controller.

[0003] In the existing lifting tables, side plates are usually fixed to both sides of the frame by screws, and the side plates are connected and fixed to the tabletop by bolts. The end of the bolt is likely to cause indentation damage to the surface of the side plate; when the surfaces of the side plate or the tabletop are uneven, it is very difficult to ensure full contact between the side plate and the tabletop, which will affect the fastening property of the bolt and is prone to looseness. Summary of the Invention

[0004] The purpose of the utility model is to solve the above-mentioned technical problems existing in the prior art, and provide an electric lifting table which is easy to lift, with a novel structure. The fastening screws are in close contact with the side plate and the tabletop through protective pads, avoiding indentation damage to the surface of the side plate by the fastening screws, playing a simple protection role, and improving the fastening property of the fastening screws, and not being prone to loosen freely.

[0005] In order to solve the above-mentioned technical problems, the utility model adopts the following technical scheme:

[0006] An electric lifting table which is easy to lift, comprising: a tabletop, telescopic columns, a frame, and side plates. A driving box is arranged at the top of the telescopic columns, the driving box is arranged inside the frame, the side plates are symmetrically distributed on the frame, and the tabletop is arranged on the side plates; it is characterized in that: protective pads are arranged on the side plates, fastening screws are inserted through the protective pads, and the fastening screws are fixedly connected with the tabletop. The lifting table has a novel structure. The fastening screws are in close contact with the side plate and the tabletop through the protective pads, avoiding indentation damage to the surface of the side plate by the fastening screws, playing a simple protection role, and improving the fastening property of the fastening screws, and not being prone to loosen freely.

[0007] Furthermore, end bolts are inserted through the side plates, and limit screw holes are arranged on the frame and are in fit connection with the end bolts, so that the side plates can be detachably and limit-connected to the frame. The fixation is reliable, the side plates are convenient to disassemble and assemble, can be used immediately after installation, and are flexible and convenient.

[0008] Furthermore, a rubber ring is provided on the frame, and positioning columns are provided at the bottom of the side plate. The positioning columns are adapted to the middle holes of the rubber ring. A spherical portion is provided on the positioning column, and the cross-sectional diameter of the spherical portion is larger than the cross-sectional diameter of the positioning column. The positioning column passes through the middle hole of the rubber ring, and the spherical portion restricts the positioning column from freely disengaging from the rubber ring. During installation, the spherical portion is squeezed into the middle hole of the rubber ring to deform the middle hole of the rubber ring. When the spherical portion passes through the middle hole of the rubber ring, the middle hole of the rubber ring returns to its original shape, and the positioning column is located in the middle hole of the rubber ring. The spherical portion blocks the positioning column from freely disengaging from the middle hole of the rubber ring, realizing the limit of the side plate on the frame, which is stable and reliable; during disassembly, the side plate is lifted upward forcefully to make the spherical portion pass through the middle hole of the rubber ring, and the side plate can be separated from the frame, replacing the bolt fixing method, which is labor-saving and convenient for disassembly and assembly.

[0009] Furthermore, limiting through holes are provided on the frame. The rubber ring includes a middle portion and end portions. The end portions are provided at both ends of the middle portion. The middle portion is adapted to the limiting through holes. The cross-sectional diameter of the end portions is larger than the cross-sectional diameter of the middle portion to limit the axial movement of the middle portion in the limiting through holes. During installation, the rubber ring is squeezed to deform it until one end portion passes through the limiting through hole, and the middle portion is located in the limiting through hole. After the force is removed, the two end portions block the middle portion from freely disengaging from the limiting through hole, ensuring reliable installation and facilitating the replacement of the rubber ring.

[0010] Furthermore, installation through holes are provided on the side plate. The protective pad includes a column body with a middle hole and retaining rings. The retaining rings are provided at both ends of the column body. The column body is adapted to the installation through holes. The cross-sectional diameter of the retaining rings is larger than the cross-sectional diameter of the installation through holes to limit the axial movement of the column body in the installation through holes. During installation, the protective pad is squeezed to deform it until one retaining ring passes through the installation through hole, and the column body is located in the installation through hole. After the force is removed, the two retaining rings block the column body from freely disengaging from the installation through hole, ensuring reliable installation and facilitating the replacement of the protective pad.

[0011] Furthermore, the frame includes a central tube, a sleeve, and side plates. The sleeves are provided at both ends of the central tube, and the side plates connect the two sleeves. The drive box is fixedly connected to the sleeve by bolts. The frame structure is stable and not prone to falling apart freely, protecting the drive box from direct external impacts and having good protection performance.

[0012] Furthermore, reinforcing pieces are provided between adjacent sleeves. The provision of the reinforcing pieces makes the adjacent sleeves integrated and not prone to relative movement with each other, improving the structural stability of the frame; the reinforcing pieces are fixedly connected to the tabletop by bolts, and the multi-point connection and fixation improve the firmness of the tabletop installed on the frame.

[0013] Due to the adoption of the above technical solutions, the present utility model has the following beneficial effects:

[0014] 1. The fastening screws are in close contact with the side panels and table tops through the protective pads, which prevents the fastening screws from causing indentation damage to the surface of the side panels, plays a simple protective role, and increases the contact area between the fastening screws and the table tops, improves the fastening, and is not easy to loosen freely.

[0015] 2. The side panels and the frame are connected in a detachable manner, which can be divided into the following two types:

[0016] ① Install end bolts on the side panels and screw the end bolts to the limiting screw holes on the sleeves to fix the side panels to the frame reliably and prevent them from loosening freely.

[0017] ② Squeeze the ball at the bottom of the side panel into the middle hole of the rubber ring on the frame to deform the middle hole of the rubber ring. After the ball passes through the middle hole of the rubber ring, the middle hole of the rubber ring returns to its original shape, and the positioning column is located in the middle hole of the rubber ring. The ball blocks the positioning column from freely escaping from the middle hole of the rubber ring, thereby limiting the side panel on the frame, which is stable and reliable. When disassembling, lift the side panel upward with force to make the ball pass through the middle hole of the rubber ring. The side panel can be separated from the frame, replacing the bolt fixing method, and the disassembly and assembly is labor-saving and convenient. BRIEF DESCRIPTION OF THE DRAWINGS
