Description

TECHNICAL FIELD

The present disclosure relates to the field of office furniture, in particular to a lifting desk support having rapid mounting structures and a lifting desk comprising the rapid mounting structures.

BACKGROUND

When the lifting desk is assembled, the support plays a key role in supporting the desk top and connecting the desk leg. Ordinary supports are generally composed of cross beams and longitudinal beams. During assembly, the support is connected with the desk legs by bolts. When customers assemble cross beams and longitudinal beams, they need to tighten the bolts to realize the assembly connection between the support and the desk legs. The process is relatively complicated and wastes a lot of time and manpower.

In order to save time and labor costs, the industry has gradually replaced the original screw assembly with welding, where cross beams and longitudinal beams are welded together. The locking and fastening of the desk surface support and the desk leg are achieved through a rapid mounting structure. This structure simplifies the assembly steps and saves time and manpower. However, since longitudinal beams and cross beams need to be welded vertically, the packaging size of the whole desk surface support is greatly increased, resulting in increases in the packaging cost, decreases in the number of desk surface supports packaged, and increases in the cost of a single product. In addition, the welding of longitudinal beams and cross beams makes the production process more complicated and easily causes local thermal deformation and environmental pollution, which is really undesirable.

In order to replace the welding process, rivets were used to connect cross beams and longitudinal beams, which put forward higher requirements for workers' operation steps and parts positioning. Rivet connection increases the cost and is prone to loose, which is also undesirable.

Therefore, a support structure with low cost, simple processing procedure, and fast and convenient connection between cross beams and longitudinal beams is required to meet the requirements of customers.

SUMMARY

To solve the problems existing in the above background art, an improved lifting desk support having rapid mounting structures and a lifting desk comprising rapid mounting structures are provided.

The technical scheme adopted by the present disclosure to solve the technical problems is as follows: a lifting desk support having rapid mounting structures, comprising a cross beam assembly, a longitudinal beam, a lifting desk leg, and a baseboard, with the cross beam assembly being mounted above the lifting desk leg, the baseboard being mounted below the lifting desk leg, and the longitudinal beam being mounted at a side end of the cross beam assembly. In some embodiments, the cross beam assembly and the longitudinal beam are provided with at least one set of rapid mounting structures, which comprise a boss arranged on the longitudinal beam and a notch on the cross beam assembly. In some embodiments, the boss is embedded into the notch to realize connection between the cross beam assembly and the longitudinal beam.

In some embodiments, the boss comprises a locking block and a connecting part, the notch comprises a first groove section and a second groove section which are communicated with each other. The first groove section is used for the locking block to pass through, and the second groove section is used to limit the locking block. In some embodiments, the first groove section and the second groove section are connected, and the locking block passes through the notch through the first groove section and enters the second groove section of the notch by applying a transverse force in an axial direction of the cross beam, to achieve the spacing.

In some embodiments, the boss is formed by bending and extending downwards from a plane of the longitudinal beam. In some embodiments, the locking block and the upper surface of the longitudinal beam have a slope. In some embodiments, when the locking block is mounted into the second groove section, the locking block and the upper surface of the longitudinal beam are arranged on opposite sides of the plane of the cross beam assembly respectively, and the locking block is gradually clamped against the tube wall of the cross beam assembly by applying a transverse force in the axial direction of the cross beam, thus realizing the locking between the longitudinal beam and the cross beam assembly.

In some embodiments, in the direction perpendicular to the axis of the cross beam assembly, a width of the first groove section is greater than that of the second groove section, a width of the locking block is less than or equal to that of the first groove section and greater than that of the second groove section, and the width of the locking block is greater than that of the connecting part.

In some embodiments, the notch may also include a third groove section. The first groove section and the third groove section are respectively arranged on both sides of the second groove section, and the second groove section and the third groove section are respectively communicated with the first groove section.

In some embodiments, the cross beam assembly may be of left and right split structures, which are slidably connected through connecting beams to realize axial expansion.

In some embodiments, the cross beam assembly comprises two cross beams arranged in parallel and fixed by several bridge pieces.

In some embodiments, at least one end of the connecting beam is provided with a spacing device, and the cross beam assembly is fixedly connected with a fastening device which can be used for fixing the connecting beam, such that the expansion range is limited through the cooperation between the spacing device and the fastening device.

In some embodiments, after the longitudinal beam is assembled with the cross beam assembly, fastening screws passes through a preset through-hole on the longitudinal beam and a preset through-hole on a bridge piece to connect the support with a desk top.

The technical scheme adopted by the present disclosure solves the defects in the background art and has the following advantages:

• • 1. Rapid assembly of the longitudinal beam and the cross beam assembly improves assembly efficiency and saves labor costs;
  • 2. The rapid assembly and disassembly of the longitudinal beam and cross beam assembly reduces the packaging volume and increases the number of desk surface supports to be packaged;
  • 3. As the most preferred double notch-double boss pairing setting, it ensures that the desk surface is level and the user experience is upgraded;
  • 4. The rapid mounting structure is simple and requires fewer types of parts;
  • 5. The notch on the cross beam assembly and the boss on the longitudinal beam can be made by die stamping. The process is simple and reduces material costs and manual processing costs; and
  • 6. The setting of expansion and the spacing device matches desk tops with different lengths, which improves the universality of the support.
