Description

Technical field

[0001] The present disclosure relates to the field of office furniture, in particular a lifting table bracket with a quick-mounting structure and a lifting table with this quick-mounting structure. State of the art

[0002] The bracket plays a crucial role in the assembly of the lift table, supporting the tabletop from above and connecting it to the table legs at the bottom. Typical brackets usually consist of crossbeams and longitudinal beams; during assembly, the bracket and table legs are joined using screws. Customers must tighten these screws to create the connection between the bracket and the table legs. This process is relatively cumbersome and requires considerable time and effort.

[0003] To save time and labor costs, the industry has gradually introduced welding instead of traditional screw assembly. In this construction method, crossbeams and longitudinal beams are welded together, and a quick-assembly mechanism is used to lock the tabletop support and table legs. This structure simplifies the assembly process and saves time and labor. However, with regard to packaging, the necessary right-angle welding of the longitudinal and crossbeams significantly increases the overall dimensions of the tabletop support, thereby increasing packaging costs, reducing the number of units per container, and inevitably raising the unit cost. Furthermore, welding the longitudinal and crossbeams makes the manufacturing process more complex, increases the risk of local thermal expansion of the components, and raises environmental concerns, which is why this solution is considered inadvisable.

[0004] As a replacement for welding, the crossbeam was subsequently joined to the longitudinal beam using rivets. However, this placed higher demands on the operators' work processes and the positioning of the components. The riveted connection also increased costs and was prone to loosening, which is also not recommended.

[0005] Therefore, a support structure is needed that is cost-effective, has a simple manufacturing process, and allows for a quick and convenient connection between crossbeams and longitudinal beams to meet customer requirements. Summary

[0006] The present disclosure aims to solve the technical problem by providing an improved lifting table bracket with a quick-mounting structure and a lifting table with this quick-mounting structure, in order to address the aforementioned problems of the background technology.

[0007] The present disclosure solves the technical problem by the following technical solution: A lifting table bracket with a quick-assembly structure, comprising a crossbeam assembly, longitudinal beams, lifting table legs and base plates, wherein the crossbeam assembly is arranged above the lifting table legs, the base plate is arranged below the lifting table legs and the longitudinal beams are attached to the end faces of the crossbeam assembly, characterized in that at least one group of quick-assembly structures is provided on the crossbeam assembly and the longitudinal beams, wherein the quick-assembly structures comprise projections on the longitudinal beams and grooves on the crossbeam assembly, and the projections engage in the grooves to realize the connection of the crossbeam assembly with the longitudinal beams.

[0008] Furthermore, the projection includes a locking block and connecting parts, wherein the first groove section and the second groove section are connected to each other, the groove comprising a first groove section for passing the locking block and a second groove section (1) for limiting the locking block.

[0009] Furthermore, the groove can also include a first, second and third groove section, wherein the first and third groove sections are arranged on both sides of the second groove section, and the second and third groove sections are each connected to the first groove section.

[0010] Furthermore, the locking block has an angle of inclination relative to the upper surface of the longitudinal beam.

[0011] The locking block is then inserted into the groove through the first groove section. By applying a transverse force in the direction of the crossbeam axis, the locking block enters the second groove section. Upon insertion of the locking block into the second groove section, the locking block and the upper surface of the longitudinal beam are positioned on opposite sides of the plane of the crossbeam assembly. By applying a transverse force in the direction of the crossbeam axis, the locking block and the pipe wall of the crossbeam assembly are progressively locked, thus achieving a locking connection between the longitudinal beam and the crossbeam assembly.

[0012] Furthermore, in a perpendicular direction to the axis of the crossbeam assembly, the width of the first groove section is greater than that of the second groove section, the width of the locking block is less than or equal to the width 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.

[0013] Furthermore, the projection is formed from a downwardly curved plane of the longitudinal beam.

[0014] Furthermore, the crossbeam assembly can be designed as a left- and right-divided structure, wherein the left- and right-divided structure is slidably connected via the connecting beam to allow axial telescoping.

[0015] Furthermore, the crossbeam assembly comprises two parallel crossbeams fastened by several bridge plates.

[0016] Furthermore, the connecting beam is provided with a stop device at least at one end, and a fastening device is firmly attached to the crossbeam assembly, which serves to fix the connecting beam; the telescopic range is limited by the interaction of the stop device and the fastening device.

[0017] Furthermore, after the longitudinal beam has been mounted with the crossbeam assembly, fastening screws can be guided through through holes provided on the longitudinal beam and through holes provided on the bridge plate to connect the bracket to a table top.

[0018] The beneficial effect of the present disclosure is to remedy the deficiencies existing in the background technology and to offer the following advantages: 1. Quick assembly of the longitudinal beams with the crossbeam assembly, thereby increasing assembly efficiency and reducing labor costs; 2. Quick assembly and disassembly of the longitudinal beams with the crossbeam assembly, thereby reducing the packaging volume and increasing the number of units that can be loaded per container; 3. As the optimal pairing of the double groove-double protrusion configuration, it ensures the horizontal alignment of the tabletop and improves the user experience; 4. The quick-assembly structure is simple in design and requires only a few different components; 5. The groove of the crossbeam assembly and the projections of the longitudinal beams can be produced by stamping dies, which simplifies processing and reduces material and labor costs; 6. The arrangement of telescopic and stop devices allows adaptation to tabletops of different lengths and increases the versatility of the support.

Detailed descriptions

[0019] The present disclosure will now be explained in more detail with reference to the accompanying drawings and preferred embodiments. All these figures are simplified schematic representations and serve solely to schematically illustrate the basic structure of the present disclosure; therefore, they show only the components relevant to the present disclosure. Example 1

[0020] As in Fig. 1 to Fig. Figure 10 shows a lifting table bracket with a quick-assembly structure comprising a crossbeam assembly, longitudinal beams 3, lifting table legs 10 and base plates 14. The crossbeam assembly is arranged above the lifting table leg 10, the base plate 14 is arranged below the lifting table leg 10, and the longitudinal beams 3 are arranged at the end faces of the crossbeam assembly, and bridge plates 21 are provided on the crossbeam assembly.

[0021] As in Fig. As shown in Figure 1, two sets of quick-assembly structures are provided on the crossbeam assembly and on the longitudinal beam 3, wherein there is a projection 4 on the longitudinal beam 3 and a groove 1 on the crossbeam assembly.

[0022] As in Fig. As shown in Figure 4, the groove 1 comprises a first groove section 11 and a second groove section 12;

[0023] As in the Fig. As shown in Figures 5-6, the projection 4 comprises a locking block 41 and connecting elements 42. The projection 4 is formed from a downwardly bent plane of the longitudinal beam 3. The locking block 41 has an angle of inclination to the upper surface 32 of the longitudinal beam 3.

[0024] As in Fig. As shown in Figures 1-2, in the perpendicular direction to the axis of the crossbeam assembly, the width of the first groove section 11 is greater than the width of the second groove section 12; the width of the locking block 41 is less than or equal to the width of the first groove section 11 and greater than the width of the second groove section 12; the width of the locking block 41 is greater than the width of the connecting part 42.

[0025] As in the Fig. As shown in Figures 7-10, two crossbeam assemblies are initially arranged on both sides of the connecting beam 5.

[0026] During assembly, the locking block 41 of the projection 4 on the longitudinal beam 3 is first inserted through the first groove section 11 of the groove 1 of the crossbeam assembly. A shear force is then applied to the longitudinal beam 3 in the direction of the axis of the crossbeam 2, causing the locking block 41 to enter the second groove section 12 of the groove 1. In this position, the locking block 41 and the upper surface 32 of the longitudinal beam 3 are on opposite sides of the plane of the crossbeam assembly. As the shear force continues to be applied along the axis of the crossbeam 2, the locking block 41 and the tube wall of the crossbeam assembly gradually clamp together, thus locking the longitudinal beam 3 and the crossbeam assembly.
