Description

[Technical Field]

[0001] This utility model relates to the field of cabinet structure technology, and in particular to a cabinet panel mounting structure. [Background Technology]

[0002] In the field of cabinet structure technology, panels that do not require frequent disassembly are typically fixed with bolts. This involves pre-drilling threaded holes in both the panel and the cabinet body, and then using tools such as wrenches, electric screwdrivers, and screwdrivers to insert bolts through the through-holes in the panel and into the threaded holes in the cabinet body, thus achieving a secure connection between the panel and the cabinet. Since the panel is an exterior component, most panels require painting or powder coating treatment. During assembly, bolts often scratch the coating, resulting in cosmetic defects.

[0003] In cabinet-type panel installation structures of related technologies, there are two main methods for bolt installation of the panels: one is to use external hex bolts or internal hex bolts to connect the panel and the cabinet body, with the help of flat spring washers. This method can effectively prevent loosening under impact and vibration, and the installation method is simple. However, the bolt heads are exposed, which may cause scratches and injuries to people or other objects during use. In compact spaces, there is a risk of collision damage, and it also seriously affects the appearance and aesthetics. The other method is to use countersunk bolts to connect the panel and the cabinet body. In impact and vibration scenarios, the preload of the bolts alone is not enough to guarantee the long-term stability of the connection. It usually needs to be combined with other anti-loosening devices, which increases the cost and design complexity. Secondly, the countersunk holes that match the bolt heads are machined on the panel, which requires high machining accuracy. If the size or shape of the countersunk holes is inaccurate, it will affect the bolt installation and connection effect, increasing the installation difficulty and cost. Finally, countersunk bolts are not suitable for thin panels, because countersunk hole machining may cause excessive reduction in the strength of the connector, or even penetrate the panel.

[0004] Therefore, it is necessary to provide a new cabinet-type panel mounting structure to solve the above problems. [Utility Model Content]

[0032] Please see Figures 1-7 As shown, this utility model embodiment provides a cabinet-type panel mounting structure 100, which includes: a cabinet frame 1, a panel 2, multiple sleeves 3, multiple bolts 4, and multiple plugs 5.

[0033] The cabinet frame 1 includes a frame body 11, two mounting grooves 12 formed by recessing the periphery of one side of the frame body 11, and a plurality of screw connections 13 pre-installed on the periphery of the frame body 11.

[0034] The panel 2 is fitted onto the frame body 11 and its outer periphery is disposed within the two mounting slots 12. The panel 2 includes a first mounting plate 21, two connecting plates 23 formed by bending and extending from opposite ends of the first mounting plate 21 toward the frame body 11, and two second mounting plates 22 formed by bending and extending from the two connecting plates 23 in opposite directions and spaced apart from each other. The first mounting plate 21 has multiple clearance holes 211, and the second mounting plate 22 has multiple through holes 221. Each clearance hole 211 corresponds to any one of the through holes 221. The second mounting plate 22 is fitted to the frame body 11 so that the through holes 221 correspond to the screw connections 13. Optionally, there are four panels 2, arranged in pairs along the height direction of the cabinet frame 1.

[0035] In this embodiment, the clearance hole 211 is a structural hole in the form of a round hole, an oblong hole, a square hole, or a polygonal hole. The through hole 221 is a structural hole in the form of a round hole, an oblong hole, a square hole, or a polygonal hole.

[0036] One end of each sleeve 3 is disposed in a corresponding clearance hole 211, and the other end of the sleeve 3 abuts against the second mounting plate 22 and is directly opposite a corresponding through hole 221. The sleeve 3 is used to prevent the bolt 4 from falling off.
