Description

Technical Field

[0001] This utility model relates to the field of instrument cabinet frames, and in particular to an instrument cabinet frame that can be quickly disassembled and assembled. Background Technology

[0002] Traditional instrument cabinet frames are often constructed using square tubing and then welded together, which is inconvenient for disassembly and assembly. To meet customer requirements for detachability, convenient transportation, and frame stability, existing improvements involve using profiles and square tubing assembled and then secured with screws. For example, the utility model patent CN217268062U discloses a quick-assembly and disassembly square tubing frame structure, including several uprights and crossbeams connecting them. Connecting blocks are provided at the joints between the uprights and crossbeams, with threaded holes in the connecting blocks for bolts. The ends of the crossbeams have fasteners corresponding to the connecting blocks, and the sides of the crossbeam ends have first operating grooves. By directly drilling screw holes in the square tubing frame and assembling it with bolts, connecting blocks, and fasteners, the installation process can be quick and standardized. While this type of frame assembly structure is simple and easy to operate, gaps can easily appear at the joints between the square tubing, resulting in insufficient fit and tightness at the joints of the frame components. Components such as connecting blocks still require welding for fixation, and the welding positions need to be marked before welding, making the process complex. Utility Model Content

[0003] Therefore, in order to solve the above problems, this utility model provides an instrument cabinet frame that can be quickly assembled and disassembled.

[0004] This utility model is achieved through the following technical solution: A quick-assembly and disassembly instrument cabinet frame includes front and rear crossbeams, front and rear longitudinal beams, and left and right crossbeams. The front and rear longitudinal beams are four first profiles, the front and rear crossbeams are four second profiles, and the left and right crossbeams are four square tubes. Each first profile has a first positioning part on its connection surface with a second profile. The first positioning part includes a first positioning groove, within which multiple first fixing nuts are disposed. Each second profile contains a first connecting member. The first connecting member is L-shaped, with its first side connected to the inner wall of the second profile and its second side positioned at the connection point between the second profile and the first profile. On the joint surface, multiple first bolts are provided, each corresponding to and locked with a first fixing nut. The first profile has a second positioning part on the joint surface with the square tube. The second positioning part includes a second positioning groove, and multiple second fixing nuts are provided in the second positioning groove. A second connector is provided inside the square tube. The second connector is L-shaped, and its first side is connected to the inner wall of the square tube. Its second side is located on the joint surface between the square tube and the first profile, and multiple second bolts are provided thereon. Each second bolt corresponds to and locked with a second fixing nut.

[0005] Preferably, the first positioning groove opens in the direction of the second profile, and a first abutting part extending inward is formed at the opening of the first positioning groove, the first abutting part abutting against the first fixing nut; the second positioning groove opens in the direction of the square tube, and a second abutting part extending inward is formed at the opening of the second positioning groove, the second abutting part abutting against the second fixing nut.

[0009] Preferably, the top and bottom panels, front and rear panels, and side panels are provided with multiple sets of heat dissipation holes and wiring holes.

[0010] Preferably, the upper and lower panels are each provided with two first positioning rods on their bottom sides. The first positioning rods are fixed on the front and rear crossbeams and connected between the left and right crossbeams. The upper surface of the first positioning rods and the upper surface of the front and rear crossbeams form a height difference that is the same as the thickness of the upper and lower panels.

[0011] Preferably, the front and rear panels are provided with two parallel second positioning rods at the top and bottom of their inner sides, respectively. The second positioning rods are fixed on the front and rear crossbeams and connected between the front and rear longitudinal beams.

[0012] Preferably, the outer surfaces of the front and rear longitudinal beams are provided with arc-shaped edging along their length at the corners.

[0013] The beneficial effects of this utility model's technical solution are mainly reflected in: The front and rear crossbeams, front and rear longitudinal beams, and left and right crossbeams are made of three different types of profiles or square tubes. The first profile is equipped with various connection and limiting structures that match the second profile and square tubes. Meanwhile, the second profile and square tubes match the first profile through L-shaped connectors. In addition to bolt locking, multiple mating is achieved by combining positioning parts and connectors. Various connection components match and limit each other, and locking can be achieved with just bolts. This makes the connection structure easy to disassemble and assemble and fit tightly. Thus, it can achieve both quick disassembly and assembly of the overall frame and tight fit. Attached Figure Description
