Abstract
Description
Technical Field
[0001] This utility model relates to the field of furniture technology, and in particular to a connection structure for panel furniture. Background Technology
[0002] Panel furniture, also known as engineered wood furniture, refers to furniture that is assembled and disassembled using engineered wood as the main material and panels as the basic structure. Therefore, the differences in shape, size, and structure determine the diversity of its connection methods.
[0003] Representative pieces of panel furniture include wardrobes, bookcases, TV cabinets, and dining tables. The production process of panel furniture typically involves large-scale processing and production in factories, including processes such as cutting, sanding, drilling, inserting, and sewing.
[0004] In actual use, the following shortcomings were found in the assembly of existing panel furniture:
[0005] Panel furniture is typically assembled using three-in-one connectors, screws, eccentric wheels, and other connecting components. The assembly of existing panel furniture usually relies on pre-drilled holes. If the hole positions are misaligned (due to production errors or transportation collisions), the screws and connectors may not be aligned, requiring repeated adjustments or even re-drilling. Ordinary users lack professional tools, making it difficult to manually adjust the hole positions, especially for concealed connection structures that require three-dimensional alignment, which makes the operation even more difficult.
[0006] Furthermore, in pursuit of a simple appearance, some connecting structures are hidden inside, making them impossible to observe directly during installation. They rely on feel or experience, and some furniture needs to be assembled in a specific order. An incorrect order may prevent subsequent steps from being completed.
[0007] Therefore, this application provides a panel furniture connection structure to meet the requirements. Utility Model Content
[0008] The purpose of this utility model is to solve the problems existing in the above-mentioned background technology and to propose a panel furniture connection structure.
[0009] To solve the above-mentioned technical problems, this utility model provides the following technical solution:
[0010] A panel furniture connection structure includes: a tabletop, a connecting seat, a wedge block, a sealing block, table legs, a first insert block, and a second insert block. The tabletop has mounting grooves at its four ends at the bottom, a first wedge-shaped groove on its side, a connecting seat installed in the mounting groove, a wedge block installed in the first wedge-shaped groove, a second wedge-shaped groove at the upper end of the connecting seat, a first insertion groove at the middle of the bottom of the connecting seat, a second insertion groove at the bottom of the connecting seat located on the side of the first insertion groove, an injection hole on the side of the connecting seat, a sealing block installed in the injection hole, table legs installed at the bottom of the connecting seat, a first insert block cut at the middle of the top of the table legs, and a second insert block cut at the top of the table legs located on the side of the first insert block.
[0011] Preferably, the first wedge groove is provided in four sets, and the four sets of first wedge grooves are located at the front and rear ends of the left and right sides of the table.
[0012] Preferably, the first wedge groove is connected to the bottom of the tabletop, and the other end of the first wedge groove extends laterally to the mounting groove and is connected to the mounting groove.
[0013] Preferably, the connector is embedded in the mounting groove of the tabletop, and the second wedge-shaped groove at the upper end of the connector is at the same horizontal plane as the first wedge-shaped groove.
[0014] Preferably, the wedge block, the first wedge groove, and the second wedge groove are all trapezoidal in shape, and the wedge block extends laterally through the first wedge groove and the mounting groove to the second wedge groove of the connecting seat to fix the connecting seat to the bottom of the table.
[0015] Preferably, both the first and second inserts are rectangular in shape, the first insert fits into the first insertion slot, the second insert fits into the second insertion slot, and the table leg is engaged with the connecting seat through the first and second inserts.
[0016] Preferably, the glue injection hole is located on the side of the second insertion groove, and the glue injection hole is connected to the second insertion groove.
[0017] Compared with the prior art, this utility model has at least the following beneficial effects:
[0018] In the above solution, a first wedge-shaped groove is provided on the side of the tabletop, and a wedge is inserted into the first wedge-shaped groove. The wedge extends laterally through the first wedge-shaped groove and the mounting groove to the second wedge-shaped groove of the connecting seat, thus fixing the connecting seat to the bottom of the tabletop. This structure forms a through-and-through splice form, which has high structural joint strength and is very convenient to assemble. At the same time, no other connecting parts are required.
[0019] In the above solution, the table legs are engaged with the connecting seat through the first and second inserts. By using the insert method, the table legs and the connecting seat are connected as a whole, eliminating the gaps between the joints in the traditional structure and eliminating the need to seal and fill the gaps between the boards.
[0020] In the above solution, glue is injected into the injection hole using a glue gun. Due to gravity, the glue flows from the injection hole into the second insertion groove, bonding the second insertion block into the groove. By injecting the glue inside the connection structure, the problem of glue easily overflowing from the joint and adhering to the board surface during traditional board glue injection is solved. This avoids leaving marks after filling, resulting in a smoother and more aesthetically pleasing furniture appearance. Furthermore, injecting the glue inside the board makes it less susceptible to external factors that could cause glue aging, resulting in a more stable connection. Attached Figure Description
