[0022] The utility model is further described in detail below in conjunction with the accompanying drawings. The following embodiments are only used to more clearly illustrate the technical solution of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, rather than all of the embodiments. All other embodiments obtained by ordinary technicians in this field without making creative work are within the scope of protection of the utility model.

[0023] like Figure 1 to Figure 6As shown, the utility model provides a support assembly for a frame box, including a first support beam 1 and a second support beam 2. Both support beams are made of C-shaped steel, with a C-shaped cross section and an opening direction facing the inside of the frame box. The first support beam 1 and the second support beam 2 are respectively provided with a groove 3 extending along the length direction of the beam body, and the width of the groove is 3 cm (which can be adjusted within the range of 2 to 8 cm according to needs), and a cap beam 4 with a C-shaped cross section is embedded in the groove. The cap beam 4 is buckled with the edge of the notch of the support beam through a buckle structure bent inward on both sides (such as Figure 3 In the embodiment of the utility model, the C-shaped beam and the buckled cover beam form a closed section, and the bending resistance is improved by more than 30%. The vertical load of the frame box is transmitted to the support beams at the four corners through the base, and the stress is dispersed by the beam body of the C-shaped section, which not only meets the load requirements of the frame box bracket assembly, but also reduces the weight of the bracket assembly, reduces the processing cost of the frame box, and improves the economic benefits of the enterprise.

[0024] In the embodiment of the utility model, the first support beam 1 and the second support beam 2 are respectively provided with long grooves 8 on their inner sides, and the cap beam 4 is provided with bosses 9 on their outer sides, and the bosses 9 are connected with the long grooves 8 in abutment. The connection structure between the support beam and the frame box base is as follows: the first support beam 1 and the second support beam 2 are respectively provided in two groups, each group including one first support beam and one second support beam, a total of four support beams, which are respectively installed vertically at the four corners of the frame box base. The L-shaped groove 7 at the end of the support beam opens downward and is plugged into the metal plate at the edge of the base (specifically, the depth of the L-shaped groove is 1.5 cm, which matches the thickness of the base plate. In the embodiment of the utility model, the fixing structure of the cap beam and the support beam is: the cap beam 4 is inserted into the groove 3 of the first support beam 1 and the second support beam 2 respectively, and the lateral limit is achieved by the interference fit of the outer boss 9 and the long groove 8 on the inner side of the support beam (specifically, 4 long grooves are set on each side, with a spacing of 10 cm). In the embodiment of the utility model, the L-shaped groove plug-in and bolt alignment design reduces the installation time by 50%, greatly improves the assembly efficiency of the frame box, and improves the practicality of the frame box. The buckle structure between the cap beam 4 and the support beam can also resist lateral force, and the cooperation between the boss 9 and the long groove 8 further limits the displacement and enhances the lateral stability of the frame box.

[0025] The first support beam 1 is provided with a screw hole 5, and the second support beam 2 is provided with a through hole 6, and the position of the through hole 6 corresponds to the screw hole 5. Specifically, a rivet nut (the screw hole diameter is 8mm) is riveted on the side of the first support beam 1, and a through hole 6 with a diameter of 10mm is provided at the corresponding position of the second support beam 2. During installation, the bolt passes through the through hole 6 and is screwed into the rivet nut, and the two support beams (such as Figure 4 As shown). In a further embodiment, an anti-loosening measure is added: a spring washer is installed on the bolt head to prevent loosening caused by vibration.

[0026] The first support beam 1 and the second support beam 2 are respectively provided with a plurality of slots 10, and the slots 10 are respectively arranged on both sides of the screw hole 5 or on both sides of the through hole 6. Specifically, long straight slots (length 15mm, width 2mm) are respectively provided on both sides of the screw hole 5 or the through hole 6 of the first support beam 1 and the second support beam 2 for plugging and matching with the plug-in crossbeam to enhance the stability of the frame box.

[0027] Of course, the above embodiments are not intended to limit the present invention, and the present invention is not limited to the above examples. Any changes, modifications, additions or substitutions made by technicians in this technical field within the essential scope of the present invention should also fall within the protection scope of the present invention.
