Description

Technical Field

[0001] The utility model relates to the field of gas tank covers, in particular to a connection structure of various groups of plates of a gas tank cover. Background Art

[0002] Traditional furniture, such as cabinets, is made up of multiple panels. The common connection structures used between the panels include mortise and tenon joints, panel joints, and other auxiliary connection methods. The following is a detailed analysis of these connection structures and their shortcomings:

[0003] 1. Mortise and tenon connection

[0004] Connection method:

[0005] The mortise and tenon structure is a common connection method in traditional Chinese furniture. It uses delicate and accurate mortise and tenon joints to tightly combine and connect the various parts of the furniture to form a strong and firm whole.

[0006] In furniture such as cabinets, mortise and tenon joints are commonly used at the corners of the frame structure, such as right-angle joints and bevel joints. Right-angle joints offer greater stability and are often made with straight tenons and dovetail joints. Bevel joints, on the other hand, offer a more aesthetically pleasing design but are less strong and more complex to fabricate.

[0007] Disadvantages:

[0008] High processing technology requirements: The production of mortise and tenon structure requires superb carpentry skills. If it is not properly controlled, it is easy to cause processing defects, such as loose tenon, incorrect tenon shoulder sawing, etc.

[0009] Relatively low production efficiency: Since the production of mortise and tenon structures requires manual operation, its production efficiency is lower than that of modern mechanical connection methods.

[0010] 2. Panel Connection

[0011] Connection method:

[0012] Panel joining is the process of joining narrow solid wood boards into boards of the required width, which is commonly seen in solid wood table tops, solid wood door panels and chair seat panels.

[0013] In cabinets, panel connections are usually used to make panels, side panels and other parts. Common panel structures include dragon and phoenix tenon joints, thick plank straight tenon joints, etc.

[0014] Disadvantages:

[0015] Easy to deform: Due to the hygroscopicity and drying properties of wood, the joints of the panels may deform after long-term use, especially the two end faces are most likely to warp or even crack.

[0016] High requirements for materials: In order to ensure the stability and aesthetics of the panel connection, the tree species and moisture content in the same panel parts should be consistent.

[0017] 3. Other auxiliary connection methods

[0018] Connection method:

[0019] In traditional furniture, in addition to mortise and tenon joints and panel joints, other auxiliary connection methods are also used, such as nail connections, glue connections, etc. These connection methods are usually used to reinforce or repair the furniture structure.

[0020] Disadvantages:

[0021] Nail connection: Nail connection can easily damage wood fibers and affect the stability of the wood. At the same time, if the nails break or loosen, it will affect the structural stability of the furniture.

[0022] Glue connection: Although glue connection can strengthen the furniture structure, the glue may age and fail after long-term use, causing the furniture parts to loosen or fall off.

[0023] In summary, the connection structures used in traditional multi-panel furniture each have their advantages and disadvantages. In practical applications, the appropriate connection method should be selected based on a comprehensive consideration of factors such as the furniture's intended use, material properties, and production process. Furthermore, to extend the lifespan and maintain the aesthetic appeal of the furniture, regular maintenance and upkeep are essential. Summary of the Invention

[0024] Aiming at the shortcomings of various traditional connection processes, the present invention provides a gas tank cover with high assembly efficiency, stable assembly, and easy maintenance and care.

[0025] In order to achieve the above purpose, the technical solution provided by the utility model is:

[0026] A spliced ​​gas tank cover with a multi-directional limit connection includes an upper cover and two or more side panels, the top ends of the side panels are connected to the lower end surface of the upper cover, and the connection between the upper cover and the side panels is provided with one or more splicing parts, and the splicing parts include a multi-directional pin and a multi-directional slot; the multi-directional pin is provided with limit plates in more than two directions, and the multi-directional slot is provided with mounting slots in more than two directions, and at least two limit plates on the multi-directional pin extend into the mounting slots of the multi-directional slot; there are at least two connected plates in the upper cover and the side panels, one of which is fixed with a multi-directional pin, and at least one of the other plates is fixed with a multi-directional slot.

[0027] The multi-directional slot is provided with more than two limiting side columns and more than one limiting middle column, and the limiting plate in one direction of the multi-directional latch is inserted between one limiting side column and one limiting middle column.

[0028] The multi-directional slot is provided with two limiting side posts and two limiting middle posts.

[0029] The multi-directional slot is matched with two multi-directional pins.

[0030] The multi-directional latch is provided with an L-shaped latch and a top sealing cover plate. The top sealing cover plate is provided on the top of the L-shaped latch and covers the horizontal and vertical parts of the L-shaped latch. When the L-shaped latch is fully inserted into the multi-directional slot, the slot surface of the multi-directional slot abuts against the top sealing cover plate, so that the multi-directional latch can only be separated from the multi-directional slot in one direction in the initial stage of separation.

[0031] The upper cover is provided with more than one multi-directional slot, and at least two side panels are provided with multi-directional pins.

[0032] The present invention innovatively proposes a matching scheme of multi-directional pins and multi-directional slots, which not only realizes any number of connection points between two interconnected boards, but more importantly, each connection point has limits in more than two directions. Therefore, after assembly, the separation direction of the boards is unique and they can only be disassembled in this direction. Therefore, the assembly stability is much higher than that of traditional connection schemes. Due to the matching scheme of multi-directional pins and multi-directional slots, professional tools are almost not required during the assembly process, so the users can assemble it themselves, which greatly reduces the installation cost of the factory. At the same time, it is also convenient for logistics in bulk state, which greatly saves transportation space.

[0033] The multi-directional slot of the present invention is provided with more than two limiting side columns and more than one limiting middle column. The limiting plate of one direction of the multi-directional pin is inserted between one limiting side column and one limiting middle column, which greatly improves the damage resistance of the multi-directional slot, thereby greatly increasing the number of disassembly and assembly times, and then improving the maintenance capability.

[0034] The multi-directional latch of the present invention is provided with an L-shaped latch and a top sealing cover plate, which greatly improves the assembly stability of the multi-directional latch and reduces the possibility of damage during the insertion and removal process.
