Description

Technical Field

[0001] The utility model relates to a quick-disassembly structure, in particular to a quick-disassembly structure with a tongue and groove. Background Art

[0002] Traditional equipment installation typically requires disassembly of the cabin to maintain or replace the equipment within. This makes the disassembly and assembly process cumbersome and time-consuming. To improve the ease of equipment maintenance, it is often desirable to be able to remove the equipment from the maintenance access panel for maintenance. For example, CN202322627215.3 provides a quick-release structure for disassembly and assembly of equipment with a tapered pin and pinhole, which can be used to complete equipment disassembly and assembly from the maintenance access panel. However, this structure has poor load-bearing capacity and is not suitable for heavier equipment. Utility Model Content

[0003] Purpose of the utility model: The purpose of the utility model is to provide a quick-disassembly structure that can disassemble and assemble the equipment in the cabin from the maintenance cover, which can improve the convenience of equipment maintenance; it has good load-bearing capacity and reliable connection, and is suitable for heavier equipment in the cabin; it has a simple structure, low processing difficulty, and can meet the requirements of interchangeable assembly.

[0004] Technical Solution: A mortise-and-tenon quick-release structure, comprising an equipment bracket, equipment, cabin, and maintenance access cover. The bracket features a threaded hole on the upper portion and a V-shaped mortise on the lower portion. The upper portion of the equipment features a vertical waist-shaped hole and a trapezoidal tenon on the lower portion. The tenon at the bottom of the equipment inserts into the mortise on the bracket, providing vertical support for the equipment. The waist-shaped hole on the upper portion of the equipment compensates for vertical installation deviations caused by machining variations in the mortise and tenon.

[0005] To facilitate disassembly and assembly of the equipment from the maintenance opening frame, the waist-shaped holes on the equipment and the threaded holes on the bracket should be set near the opening frame, and the equipment should have structural features with handle functions.

[0006] The bracket can be formed integrally with the cabin body, or connected by riveting, screwing, welding, etc.

[0007] The tenon can be integrally formed with the bracket, or connected by riveting, screwing, welding, or the like.

[0008] The cross-sectional shape of the mortise and tenon can be trapezoidal, triangular or other shapes.

[0009] Two or more groups of connection holes can be set according to the load conditions and space limitations in the cabin; threaded holes can also be set on the equipment as needed, and waist-shaped holes can be opened on the main structure.

[0010] Depending on the load conditions, the threaded holes and fastener connections can be prevented from loosening by using locking wire screw sleeves or self-locking support nuts, spring washers, safety wires, cotter pins, etc.

[0011] Technical Effect: This utility model implements a quick-disassembly function, ensuring smooth assembly and disassembly of equipment from the maintenance access panel. Simply disassembling the fasteners near the access panel allows for quick assembly and disassembly of the equipment. It offers excellent load-bearing capacity and is suitable for assembling heavier equipment. Its simple structure requires minimal machining precision, while also meeting the requirements for interchangeable assembly. BRIEF DESCRIPTION OF THE DRAWINGS

[0016] In order to more clearly illustrate the technical solutions of the embodiments of the present invention, the present invention is described in detail below in conjunction with the accompanying drawings or specific implementation cases. It should be noted that some (but not all) of the disclosed examples are shown in the drawings. In fact, many different examples can be described and these examples should not be understood as being limited to the examples set forth herein. On the contrary, describing these examples makes the positive effects of the present invention more apparent, and any parts not detailed herein are considered to be well-known techniques or conventional technical means in the art.

[0017] See attached Figures 1 to 3 The quick-disassembly structure designed in this embodiment consists of a bracket 1, a device 2, a cabin 3, and a maintenance cover 4. The upper part of the bracket 1 is designed with a threaded hole 5 and the lower part is designed with a mortise 6; the upper part of the device 2 is designed with a vertical waist-shaped hole 8 and the lower part is designed with a tenon 7.

[0018] Assembly steps: First, connect bracket 1 to cabin 3. This step is not required if the two are integrally formed. Second, place device 2 into cabin 3 through the opening frame, inserting the tenon 7 at the bottom of device 2 into the groove 6 and pressing down firmly. Third, adjust device 2 so that the waist hole 8 is aligned with the threaded hole 5. Install fasteners 9 to complete the installation of device 4. Finally, install maintenance cover 4.
