Description

Technical Field

[0001] This utility model relates to the field of height-adjustable desks, specifically a double-bar height-adjustable desk. Background Technology

[0002] This refers to a table whose height can be freely adjusted. One type is the seat-adjustable height table, which has a small adjustment range and is suitable for users of different heights. It is commonly used by growing children as a height-adjustable study table. The other type is the sit-stand adjustable height table, which has a larger adjustment range and can realize two modes of working: sitting and standing.

[0003] The existing double-pole height-adjustable desk includes a tabletop and a base frame. Two sets of telescopic sleeves are installed on the base frame. The tabletop is installed on the telescopic end of the sleeve. A gas spring is installed inside the sleeve to control the extension distance of the telescopic end. At the same time, a handle for controlling the gas spring is also installed under the tabletop, so that the height of the tabletop can be easily adjusted, thereby increasing its usability.

[0004] The above-mentioned technical conditions also have defects: the tabletop of the double-pole height-adjustable table usually only uses two support points to support the tabletop, which makes the part of the tabletop far from the support points unable to bear a large load, thereby reducing the effectiveness of the double-pole height-adjustable table.

[0005] Based on this, the present invention designs a double-bar lifting table to solve the above problems. Utility Model Content

[0006] The purpose of this utility model is to provide a double-bar lifting table to solve the above-mentioned technical problems.

[0007] To achieve the above objectives, this utility model provides the following technical solution: a double-rod lifting table, comprising a base frame, on which two sets of bottom tubes are fixedly connected, and telescopic tubes are slidably connected inside the two sets of bottom tubes. Gas springs and their mounting assemblies are provided inside the two sets of bottom tubes and the telescopic tubes. A bracket is fixedly connected to the top of the two sets of telescopic tubes, and a tabletop is fixedly connected to the top of the bracket. A handle is also provided on the bracket. Two sets of stabilizing rods are fixedly connected to the other side of the bottom of the bracket. A pressing post is fixedly connected to the bottom end of the stabilizing rod. One end of the pressing post is threaded. A limiting seat is fixedly connected to one side of the outer wall of the bottom tube. The pressing post is located inside the hole on the limiting seat. A knob is threaded to one end of the pressing post, and the knob can press against the limiting seat.

[0008] By adopting the above technical solution, the support effect of the tabletop can be improved, thereby increasing the load-bearing capacity of the parts of the tabletop far from the support point.

[0009] Preferably, the knob comprises a rotating part and a screwing part, the screwing part is in threaded connection with the abutting column, and one end of the screwing part can abut against the limiting seat.

[0010] By adopting the above technical scheme, the abutting against the limiting seat can be well achieved, and the use effect is improved.

[0011] Preferably, the rotating part is a regular octagon.

[0012] By adopting the above technical scheme, the rotating is facilitated.

[0013] Preferably, the two sides of the chassis are fixedly connected with cross rods, and universal wheels are further arranged on the two groups of cross rods.

[0014] By adopting the above technical scheme, the lifting table can be moved conveniently.

[0015] Preferably, the universal wheel is further provided with a locking structure.

[0016] By adopting the above technical scheme, the universal wheel can be locked, so that the universal wheel cannot be easily rotated when stopping is needed.

[0017] In summary, the present application has the following beneficial technical effects: through the arrangement of the stabilizing rod, the limiting seat, the abutting column and the knob, the load capacity of the position of the table plate far from the double-rod supporting point can be increased, the use effect of the lifting table is improved, and the stability of the table plate in use can be increased.
