Description

Technical Field

[0001] This utility model relates to the field of cabinet device technology, specifically to a cabinet door panel connection mechanism that is easy to assemble and disassemble and has reliable strength. Background Technology

[0002] Currently, there are two main methods for fixing rack side panels in the market. One method involves installing sheet metal parts with fixing screws at the rack frame side panel location, while also drilling fixing holes in the panel. Each side panel typically requires six screws to be installed on the uprights, six nuts to be installed on the fixing sheet metal parts, and six screws to be tightened. This assembly and disassembly process is cumbersome, and each rack requires a large number of nuts and screws, resulting in labor-intensive production and inconvenient assembly and disassembly. The other method involves fixing the rack side panels with clips. While this solution can improve assembly and disassembly efficiency to some extent, it suffers from problems such as weak load-bearing capacity, poor shock resistance, and instability in actual use.

[0003] Therefore, this utility model provides a cabinet door panel connection mechanism that is easy to assemble and disassemble and has reliable strength, solving the problems of time-consuming screw assembly and disassembly, and unreliable strength of snap-fit ​​methods. Utility Model Content

[0018] The present invention will now be described in detail with reference to specific embodiments. These embodiments will help those skilled in the art to further understand the present invention, but do not limit the present invention in any way. It should be noted that those skilled in the art can make several changes and improvements without departing from the concept of the present invention. These all fall within the protection scope of the present invention.

[0019] This utility model provides a cabinet door panel connection mechanism that is easy to assemble and disassemble and has reliable strength. It adopts a combination of three methods: positioning pin, buckle, and screw connection, which can not only improve the efficiency of door panel installation, but also ensure the strength of the door panel after installation.

[0020] like Figure 1 , Figure 2 and Figure 3 As shown, this embodiment features a cabinet door panel connection mechanism that facilitates assembly and disassembly and offers reliable strength. This mechanism is used for installing door panel 2 and cabinet 1. Door panel 2 is located on the side of cabinet 1. Door panel 2 is typically rectangular or square, and the side of cabinet 1 has openings to accommodate it. The connection mechanism comprises three parts: a positioning pin 11 and positioning hole 21 at the bottom for quick positioning of door panel 2 during installation; a snap-fit ​​hole 12 and snap-fit ​​22 in the middle for quick connection in the middle area; and threaded holes 13, bolt holes 23, and screws 3 at the top for a secure connection between door panel 2 and cabinet 1.

[0021] In this embodiment, the positioning hole 21 is located at the bottom edge of the door panel 2, and the positioning pin 11 is located at the bottom of the door frame area of ​​the cabinet 1, facing upwards. This allows for quick positioning of the door panel 2 during installation via the positioning hole 21 and the positioning pin 11, while maintaining the stability of the door panel 2 during installation. There are two sets of positioning pins 11 and positioning holes 21, which further improves the stability of the door panel 2 during installation. The positioning pin 11 is a stud riveted to the frame of the cabinet 1; that is, a through hole is drilled in the frame of the cabinet 1, and the stud is riveted to the frame through the through hole, forming the main structure of the positioning pin 11.

[0022] The latching holes 12 and latches 22 are located in the central area of ​​the door panel 2, with a set of latches 22 and latching holes 12 on each of the left and right sides of the door panel 2. The latches 22 are installed into the door panel 2 by being inserted. By pushing the two latches 22 to the sides respectively, the latches 22 can be pushed into the latching holes 12 for assembly; pushing them in the opposite direction pushes the latches 22 out of the latching holes 12 for disassembly. After the latches 22 are pushed into the latching holes 12, they should be able to lock securely to improve the stability of the installation. There are various ways to lock the latches 22, such as gradually reducing the diameter of the latching hole 12; or adding a flexible pin to the latches 22 to engage with the pin hole in the latching hole 12, etc.

[0023] Threaded holes 13 and bolt holes 23 are located in the upper area of ​​the door panel 2. Specifically, bolt holes 23 are located on the surface of the door panel 2, and threaded holes 13 are located on the extension device of the frame of the cabinet 1. After the bolt holes 23 and threaded holes 13 are combined, the door panel 2 and the cabinet 1 are bolted together by screwing in screws 3. Threaded holes 13 are holes with internal threads to engage with screws 3; bolt holes 23 are smooth holes. In other embodiments, screws 3 can also be replaced by bolts or other components, as long as the door panel 2 and the cabinet 1 can be fastened.

[0024] Since the door panel 2 and the cabinet 1 are positioned by the positioning pin 11 and the positioning hole 21, in order to ensure that the door panel 2 can be smoothly installed onto or removed from the positioning pin 11, there should be a gap between the upper edge of the door panel 2 and the frame of the cabinet 1, and the height of the gap should be greater than the height of the positioning pin 11 embedded in the positioning hole 21, so as to avoid the door panel 2 being blocked during installation.

[0025] Based on the easy assembly and disassembly and reliable strength of the cabinet door panel connection mechanism in this embodiment, during installation, first place the positioning hole 21 of the door panel 2 at the positioning pin 11 to lower the door panel 2, then push the buckles 22 on both sides into the buckle holes 12 on the cabinet 1 respectively. After the buckles 22 are correctly fixed, install the screws 3 through the bolt holes 23 to the threaded holes 13 to realize the installation of the door panel 2 and the cabinet 1. The effect after installation is as follows: Figure 4 As shown. After installation, the door panel 2 covers the extension device on the frame of the cabinet 1 to achieve an aesthetically pleasing appearance. During disassembly, first remove the screws 3 on the top of the door panel 2, then push the latches 22 on both sides inward, and then move the door panel 2 upward to disengage the positioning pin 11, and remove the door panel 2 from the cabinet 1.

[0026] The cabinet door panel connection mechanism of this application, which is easy to assemble and disassemble and has reliable strength, integrates three installation methods: buckle, screw, and positioning stud. It is more convenient than a single installation method, requires less installation assistance, and ensures reliable door panel installation. Its load-bearing capacity and seismic resistance are not significantly different from traditional screw fixing methods.

[0027] The specific embodiments of this utility model have been described above. It should be understood that this utility model is not limited to the specific embodiments described above, and those skilled in the art can make various changes or modifications within the scope of the claims, which do not affect the substantive content of this utility model. Unless otherwise specified, the embodiments and features described in this application can be arbitrarily combined with each other.
