Description

Technical Field

[0001] This invention relates to the field of furniture technology, specifically to a mortise and tenon connector and mortise and tenon furniture. Background Technology

[0002] Mortise and tenon joints have excellent mechanical properties and aesthetic appeal, and solid wood furniture made with mortise and tenon joints is still very popular with consumers.

[0003] Traditional furniture legs typically use mortise and tenon joints where the ends of two crossbeams are machined into 45° bevels, and tenons are machined on these ends and inserted into the mortises of the uprights. However, this type of tenon joint is complex to manufacture, resulting in higher processing costs. Furthermore, during component production, components need to be machined to precise dimensions to achieve proper assembly. Additionally, furniture legs using mortise and tenon joints are prone to deformation due to external forces or environmental factors after prolonged use, which can easily cause the tenons to fall off.

[0004] Furthermore, when using furniture, the tabletop space is limited, and depending on the usage, there may be a situation where the area is insufficient. On the other hand, an excessively large surface area will occupy too much space when placed, making it difficult for the tabletop of existing furniture to meet the usage needs according to the usage situation. Summary of the Invention

[0005] The purpose of this invention is to provide a mortise and tenon connector and mortise and tenon furniture to solve the problems mentioned in the background art.

[0006] To achieve the above objectives, the present invention provides the following technical solution: a mortise and tenon connector and mortise and tenon furniture, including a tabletop and table legs. Connecting rods are fixedly connected to the lower surfaces of the four corners of the tabletop. Two support plates are fixedly sleeved on the surface of the connecting rods. The cross-sectional shape of the support plates is "L". The long arm ends of the two support plates are slidably sleeved with fitting blocks. The upper ends of the table legs are located between the corresponding two fitting blocks. Screws are threaded into the interior of the short arm ends of the two support plates. The screws are rotatably connected to the fitting blocks. The other ends of the two screws are fixedly connected with handles.

[0007] As a preferred embodiment of the present invention, a connecting plate is fixedly connected to the lower surface of the desktop, and four lifting rods are fixedly connected to the surface of the connecting plate. The four lifting rods are arranged in pairs, and two extended surfaces are provided under the desktop.

[0008] As a preferred embodiment of the present invention, the surface of the widened surface has two connecting holes, and each pair of lifting rods is inserted into the corresponding two connecting holes on the widened surface, and a top rod is fixedly connected to the surface of the widened surface.

[0009] As a preferred embodiment of the present invention, the desktop has four storage slots inside, and the cross-sectional shape of the storage slots is "U".

[0010] As a preferred embodiment of the present invention, the storage slot on the desktop is provided with a first push rod and a second push rod, and the storage slot on the desktop is provided with a plurality of spheres.

[0011] In a preferred embodiment of the present invention, the plurality of spheres are all located between the first push rod and the second push rod.

[0012] As a preferred embodiment of the present invention, an annular frame is fixedly connected to both openings of the storage slot on the desktop, and a column block is fixedly connected to one end of the first push rod and the second push rod near the inside of the storage slot.

[0013] As a preferred embodiment of the present invention, a cover is snapped onto the annular frame, and a groove is formed on the surface of the cover.

[0014] As a preferred embodiment of the present invention, the groove is rotatably connected to a rotating shaft, and a long plate is fixedly sleeved on the surface of the rotating shaft.

[0015] Compared with the prior art, the beneficial effects of the present invention are:

[0016] 1. This invention, by setting up a locking block and screws, allows the two screws to tighten the two locking blocks respectively, clamping the upper end of the table leg. This fixes the table leg while maintaining its stability. Furthermore, if the component becomes unstable due to external forces or the influence of the surrounding environment, the screws can be used to tighten the two locking blocks again, thus fixing the table leg once more and increasing the service life of the component.

[0017] 2. This invention, by setting an extended surface, inserts the top rod into the inside of the second push rod, and aligns the connecting hole with the first push rod, allowing the first push rod to be inserted into the connecting hole on the extended surface. This connects the extended surface to the tabletop, making the entire tabletop circular, thereby increasing the usable area. When a larger area is not needed, the extended surface can be removed and fitted onto the lifting rod through the connecting hole, thus storing the extended surface while reducing the floor space occupied.

Therefore, they should not be construed as limitations on this invention. Furthermore, the terms "first" and "second" are used for descriptive purposes only and should not be construed as indicating or implying relative importance.

[0028] In the description of this invention, it should be noted that, unless otherwise explicitly specified and limited, the terms "installed," "equipped with," "connected," etc., should be interpreted broadly. For example, "connection" can be a fixed connection, a detachable connection, or an integral connection; it can be a mechanical connection or an electrical connection; it can be a direct connection or an indirect connection through an intermediate medium; it can be a connection within two components. Those skilled in the art can understand the specific meaning of the above terms in this invention based on the specific circumstances.

[0029] Please see Figure 1-7 This invention provides a technical solution for mortise and tenon connectors and mortise and tenon furniture:

[0030] according to Figure 1 , Figure 2 and Figure 3 As shown, a mortise and tenon connector includes a tabletop 1 and table legs 2. Connecting rods 306 are fixedly connected to the lower surfaces of the four corners of the tabletop 1. Two support plates 303 are fixedly sleeved on the surface of the connecting rods 306. The cross-sectional shape of the support plates 303 is "L". The long arm ends of the two support plates 303 are slidably fitted with mating blocks 302. By tightening the two mating blocks 302, the upper end of the table leg 2 can be clamped. The upper end of the table leg 2 is located between the corresponding two mating blocks 302. The short arm ends of the two support plates 303 are threaded with screws 304. The screws 304 are rotatably connected to the mating blocks 302. The mating blocks 302 can be moved by the screws 304. The other end of the two screws 304 is fixedly connected with a handle 305.

[0031] In practical use, when installing the table leg 2 and the tabletop 1 together, the table leg 2 can be placed between the two locking blocks 302, and then the two locking blocks 302 can be moved by the two screws 304 respectively, which can tighten the two locking blocks 302 and clamp the upper end of the table leg 2. Since the locking blocks 302 are in close contact with the table leg 2, the table leg 2 can be fixed and kept stable. After a long period of use, if the part becomes deformed and unstable due to external force or the influence of the surrounding environment, the two locking blocks 302 can be tightened again by the screws 304, thereby increasing the service life of the part.

[0032] according to Figure 4 , Figure 5 , Figure 6 and Figure 7 As shown, a mortise and tenon furniture with tenon and tenon connectors has a connecting plate 308 fixedly connected to the lower surface of the tabletop 1. Four lifting rods 309 are fixedly connected to the surface of the connecting plate 308. The four lifting rods 309 are in pairs. Two extended surfaces 301 are provided under the tabletop 1. Connecting the extended surfaces 301 to the tabletop 1 can increase the usable area. Two connecting holes are opened on the surface of the extended surfaces 301. Each pair of lifting rods 309 is inserted into the corresponding two connecting holes on the extended surfaces 301.

[0033] Among them, the surface of the widened surface 301 is fixedly connected to the top rod 307, and the interior of the tabletop 1 is provided with four storage slots. The cross-sectional shape of the storage slots is "U". The interior of the storage slots on the tabletop 1 is provided with a first push rod 310 and a second push rod 313. The interior of the storage slots on the tabletop 1 is provided with multiple balls 311. The movement of the balls 311 can move the first push rod 310 or the second push rod 313. The multiple balls 311 are all located between the first push rod 310 and the second push rod 313.

[0034] Among them, annular frames 314 are fixedly connected to the two openings of the storage slot on the desktop 1. A column block 312 is fixedly connected to the end of the first push rod 310 and the second push rod 313 near the inside of the storage slot. The cooperation between the annular frame 314 and the column block 312 can prevent the first push rod 310 and the second push rod 313 from falling out of the storage slot. A cover 315 is snapped on the annular frame 314. The cover 315 can keep the first push rod 310 and the second push rod 313 inside the storage slot when not needed.

[0035] The cover 315 has a groove 318 on its surface. A rotating shaft 317 is rotatably connected inside the groove 318. By pressing down on the shorter end of the long plate 316 with the rotating shaft 317 as the axis, one end of the long plate 316 can be rotated out of the groove 318. The long plate 316 is fixedly fitted on the surface of the rotating shaft 317. By pulling the long plate 316, the cover 315 can be removed from the annular frame 314 more easily.

[0036] In practical use, when a larger desktop 1 is needed, the extended surface 301 can be removed from the lifting rod 309, and then the top rod 307 can be inserted into the storage groove where the second push rod 313 is located. At this time, the connecting hole on the extended surface 301 is directly opposite the first push rod 310. Therefore, when the top rod 307 is inserted into the storage groove, it will push the second push rod 313 and multiple balls 311 to move, thereby causing the first push rod 310 to extend out of the storage groove until it is inserted into the extended surface 301. This connects the extended surface 301 to the desktop 1, making the entire desktop 1 circular, thereby increasing the usable area.

[0037] Finally, it should be noted that the above descriptions are merely preferred embodiments of the present invention and are not intended to limit the present invention. Although the present invention has been described in detail with reference to the foregoing embodiments, those skilled in the art can still modify the technical solutions described in the foregoing embodiments or make equivalent substitutions for some of the technical features. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of the present invention should be included within the protection scope of the present invention.
