Description

Technical Field

[0001] This utility model relates to the field of mechanical structure technology, and in particular to a quick-release door panel structure for use in cabinets, electrical equipment, furniture and other fields. Background Technology

[0002] Currently, traditional door panels are typically installed by directly locking them with bolts or connecting them with hinges. This type of structure suffers from problems such as inconvenient disassembly, cumbersome operation, and low efficiency. Especially in situations requiring frequent maintenance or replacement of door panels, the traditional method is not only time-consuming and labor-intensive, but repeated disassembly and assembly can also lead to wear on the connecting parts and a decrease in sealing performance. Furthermore, many fasteners on traditional door panels are exposed on the outer surface of the panel, affecting the overall aesthetics. The difficulty of disassembling and assembling traditional door panels is even more pronounced when installation space is limited.

[0003] Therefore, it is necessary to provide a new technical solution. Summary of the Invention

[0004] The present invention aims to overcome the shortcomings of the prior art and provide a door panel quick-release structure that is structurally reasonable, quick to install, easy to maintain and aesthetically pleasing.

[0005] To achieve the above objectives, the present invention adopts the following technical solution:

[0006] A quick-release door panel structure includes a quick-release door panel, a lower crossbeam, an upper crossbeam, and left and right uprights. The quick-release door panel has 90° sheet metal bends around all four edges to enhance edge rigidity and overall resistance to deformation. The upper bend of the quick-release door panel has connecting holes for threaded connection to the upper crossbeam using screws or bolts. The lower bend of the quick-release door panel has a locating pin that engages with a pin hole on the lower crossbeam to position and support the lower part of the door panel. A certain gap is maintained between the left and right bends of the quick-release door panel and the left and right uprights to form a clearance fit, or magnetic adsorption can be achieved by using magnetic plates on the uprights.

[0007] Furthermore, for door panels that are larger in size or thinner in material, additional reinforcement measures can be taken, such as reducing the area of ​​a single door panel, increasing the thickness of the panel, or welding reinforcing ribs.

[0008] Furthermore, the connection structure includes:

[0009] The connecting hole is provided on the bent edge above the quick-release door panel; and

[0010] Fastener mounting positions are provided on the upper crossbeam and correspond to the connecting holes.

[0011] The quick-release door panel is threadedly connected to the upper crossbeam using fasteners.

[0012] Furthermore, the connecting hole is a self-tapping screw hole, a through hole for installing a rivet nut, or a through hole for installing a blind rivet nut, and the fastener is installed vertically downwards. The connecting screw is screwed in vertically downwards from above, so that there are no visible fasteners on the outer surface of the door panel, resulting in a neat and aesthetically pleasing appearance.

[0013] Furthermore, when waterproofing is required, the connection structure also includes a sealing gasket disposed between the upper crossbeam and the quick-release door panel.

[0014] Furthermore, the positioning structure includes:

[0015] At least one locating pin is provided on the bent edge below the quick-release door panel; and

[0016] A pin hole provided on the lower crossbeam to mate with the positioning pin;

[0017] The locating pin and the pin hole are in a transition fit or clearance fit.

[0018] The positioning pins are fixed to the lower bent edge of the door panel by welding or fastening. A transition fit or small clearance fit is used between the positioning pins and the pin holes of the lower crossbeam to ensure accurate positioning and no wobbling at the bottom of the door panel. The number and layout of the positioning pins are rationally designed based on the size and weight of the door panel to ensure uniform and stable support.

[0019] Furthermore, the lateral fixing structure can be one of the following two methods:

[0020] a) Clearance fit structure: The left and right sides of the quick-release door panel form a clearance fit with the left and right uprights;

[0021] b) Magnetic fixing structure: The left column and / or right column are provided with magnetic plates, and the quick-release door panel is connected to the column by magnetic attraction.

[0022] Furthermore, when a magnetic fixing structure is used,

[0023] The left and right pillars are respectively provided with side guards at the positions corresponding to the left and right bending edges of the quick-release door panel;

[0024] The magnetic suction plate is fixed to the inner side of the side guard of the column;

[0025] The left and right bending edges of the quick-release door panel are aligned and fitted with the side guard edges of the column. The quick-release door panel is quickly installed and fixed by magnetic adsorption, which is especially suitable for occasions that need to be opened frequently.

[0026] The present invention has the following beneficial effects:

[0027] 1. Convenient and efficient installation and disassembly: The combination structure of upper threaded connection, lower pin hole positioning, and side gap / magnetic engagement enables quick installation and disassembly of the door panel, greatly improving maintenance and replacement efficiency, and is especially suitable for occasions that require frequent maintenance.

[0028] 2. Reliable and stable connection: It comprehensively utilizes multiple mechanical fixing methods such as threaded fastening (top), pin positioning (bottom), and clearance fit / magnetic adsorption (both sides) to ensure that the door panel can be firmly fixed in all directions without shaking, and the overall structure is stable and reliable.

[0029] 3. Neat and beautiful appearance: All major fasteners (such as screws) are hidden from the top of the door panel. There are no visible screw holes or fasteners on the outer surface of the door panel, which maintains the integrity and neatness of the door panel appearance and enhances the overall aesthetics of the product.

[0030] 4. High structural rigidity and resistance to deformation: The door panel adopts a 90° sheet metal bending edge-wrapping process, which significantly enhances the rigidity of the door panel edges and the overall resistance to deformation. For large-sized or thin door panels, further reinforcement can be achieved by adding reinforcing ribs and increasing thickness to ensure that they will not deform during long-term use.

[0031] 5. Strong adaptability and practicality: a. Waterproof adaptability: Waterproofing and seepage prevention requirements for outdoor or special environments can be met by adding sealing gaskets at the upper crossbeam connection. b. Multi-functional fixing options: Lateral fixing can be flexibly selected according to needs, using clearance fit (low cost, adaptable to thermal expansion and contraction) or magnetic fixing (for more frequent opening and closing), applicable to a wide range of scenarios. c. Strong compatibility: The structural design is suitable for multiple fields such as cabinets, electrical equipment, and furniture, exhibiting excellent versatility.

[0032] 6. Economical and easy to produce: The structure is simple and mainly adopts mature processes such as sheet metal stamping, bending and welding. The manufacturing process is simple and the cost is low, which makes it easy to produce and promote on a large scale.

[0033] Additional aspects and advantages of the invention will be set forth in part in the description which follows, and in part will be obvious from the description, or may be learned by practice of the invention. Attached Figure Description

[0034] To more clearly illustrate the technical solutions in the embodiments of the present invention or the prior art, the drawings used in the description of the embodiments or the prior art will be briefly introduced below. Obviously, the drawings described below are only some embodiments of the present invention. For those skilled in the art, other drawings can be obtained based on these drawings without creative effort.

[0035] Figure 1 This is a schematic diagram of the quick-release door panel structure provided in the embodiment.

[0036] Figure 2 This is a structural schematic diagram of the quick-release door panel provided in the embodiment. Detailed Implementation

[0037] The technical solutions of the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments.

[0038] like Figure 1 and Figure 2 As shown, the quick-release door panel structure provided in this embodiment mainly consists of a quick-release door panel 1, an upper crossbeam 2, a lower crossbeam 3, a left column 4, and a right column 5.

[0039] The quick-release door panel 1 is entirely formed from sheet metal, with 90° bends on all four sides, which not only enhances structural strength but also facilitates integration with other components. Several connection holes are pre-drilled on the top bend of the quick-release door panel 1; in this example, blind-hole rivet nuts are embedded in these holes. Corresponding through holes are provided on the upper crossbeam 2. Screws are passed through the upper crossbeam 2 from top to bottom and screwed into the rivet nuts on the door panel to achieve a secure connection at the top of the quick-release door panel 1. If waterproofing is required, a rubber sealing gasket can be installed between the upper crossbeam 2 and the door panel 1.

[0040] Two positioning pins are welded to the bottom bend edge of the quick-release door panel 1. Two corresponding pin holes are machined on the lower crossbeam 3. During installation, the positioning pins are aligned with the pin holes and inserted to achieve precise positioning and support of the bottom of the quick-release door panel 1. The positioning pins and pin holes use a clearance fit for easy assembly and disassembly.

[0041] A certain gap is left between the bent edges on both sides of the quick-release door panel 1 and the left upright 4 and right upright 5 to form a clearance fit, avoiding interference when thermal expansion and contraction or slight deformation occurs. As another implementation method, magnetic strips can also be attached to the bent edges of the left and right uprights 4 and 5, and the door panel can be directly attached and fixed during installation, which is suitable for occasions that require rapid and frequent opening and closing.

[0042] The above description is only a preferred embodiment of the present invention, but the scope of protection of the present invention is not limited thereto. Any equivalent substitutions or modifications made by those skilled in the art within the scope of the technology disclosed in the present invention, based on the technical solution and inventive concept of the present invention, should be covered within the scope of protection of the present invention.
