Description

Technical Field

[0001] This utility model relates to the field of laboratory equipment technology, and in particular to a detachable snap-fit ​​riveted laboratory cabinet. Background Technology

[0002] Early laboratory steel furniture primarily used welding and solid rivets for structural connections. While this technology offered considerable strength, its drawbacks, such as non-disassembly, rough workmanship, and high transportation costs, led to its gradual decline. To address the issue of flexible installation, bolt and nut connections emerged. However, this method presented its own problems: installation required aligning the holes, and the bolts and nuts had to be pre-tightened on both sides simultaneously, resulting in extremely low installation efficiency.

[0003] With the development of technology, self-tapping screws have come into view, but this connection method has the following shortcomings: First, the metal plate is thin and the thread length is short, which makes it easy for the screws to loosen due to long-term load or vibration, affecting the structural strength of the cabinet. Second, repeated disassembly and assembly due to maintenance can easily cause the threads of the plate to strip, loosen the connection points, and reduce the service life of the cabinet. Utility Model Content

[0004] The technical problem to be solved by this utility model is to overcome the shortcomings of the prior art and provide a detachable snap-fit ​​riveted laboratory cabinet. This detachable snap-fit ​​riveted laboratory cabinet effectively solves the above problems through snap-fit ​​and pre-embedded rivet nuts.

[0005] To achieve the above objectives, the technical solution adopted by this utility model is as follows:

[0006] A detachable snap-fit ​​riveted laboratory cabinet includes: a detachable cabinet body, a drawer installed on top of the cabinet body, and a cabinet door located below the drawer; a right-angled triangular piece with a limiting and stabilizing function is installed inside the cabinet body; the cabinet body is spliced ​​by snap-fit ​​and fastened by rivet bolts.

[0007] Preferably, the cabinet includes a door beam, a drawer beam installed on the door beam, side panels installed on both sides of the drawer beam, an upper sealing plate and a lower sealing plate installed on the side panels, a maintenance door disposed between the upper sealing plate and the lower sealing plate, a bottom plate installed on the lower sealing plate, and a kick plate installed on the bottom plate.

[0008] Preferably, several divider beams can be installed between the drawer beam and the top cover plate to separate the number of drawers.

[0009] Preferably, the lintel includes a lower beam and long supports installed on both sides of the lower beam.

[0010] Preferably, the drawer beam includes an upper beam, short supports installed on both sides of the upper beam, and a middle beam installed between the two short supports; the width of the upper beam is greater than that of the short supports; one side of the short supports is flush with one side of the upper beam.

[0011] Preferably, several divider supports can be installed between the upper beam and the middle beam to divide the number of drawers.

[0012] Preferably, the side plate includes a side cover plate, a column mounted on the side cover plate, and a track support mounted on the column; the side cover plate has a slot on the left side and a groove on the right side.

[0013] Preferably, the upper sealing plate includes an upper cover plate and first buckles disposed on both sides of the upper cover plate; rivet nuts are pre-embedded in the upper cover plate.
