Abstract
Description
Technical Field
[0001] This utility model relates to the field of furniture connection accessories technology, and in particular to a limiting alignment structure for invisible connection of furniture accessories. Background Technology
[0002] The concealed alignment structure for furniture fittings is a device used to ensure precise alignment of furniture components during the concealed connection process. Workers do not need to spend a lot of time aligning the edges and angles of the components; positioning can be achieved quickly through the cooperation of positioning pins and positioning holes. Using this alignment structure can make the installation faster than without it.
[0003] Traditional alignment structures for connecting furniture accessories typically use three-in-one connectors to fix the position. The installation process is cumbersome and inefficient. Furthermore, the screws or nuts are exposed on the outer surface of the furniture, which can damage the overall design of the wood and give people a rough, unrefined visual experience, making it unattractive.
[0004] For example, a three-in-one connection structure requires the installation of embedded parts on the board, usually a plastic or metal nut-shaped component. A hole is drilled in the other board to which it is connected, a screw is inserted, and then it is tightened by an eccentric wheel. In the furniture assembly process, such as the connection between the side panel and the shelf of a wardrobe, the embedded part is installed inside the side panel, the screw is inserted from the shelf and connected to the embedded part, and finally tightened by an eccentric wheel. The operation is cumbersome and the parts are exposed. Utility Model Content
[0005] This utility model discloses a limiting alignment structure for invisible connection of furniture accessories, aiming to solve the technical problems of limiting alignment structures for connecting furniture accessories, which usually achieve position fixation through three-in-one connectors, have complicated installation steps, low efficiency, and exposed screws or nuts on the outer surface of the furniture, which will destroy the overall design of the wood itself and give people a rough, unrefined visual feeling and an unsightly appearance.
[0006] To achieve the above objectives, the present invention adopts the following technical solution:
[0007] A limiting alignment structure for concealed connection of furniture fittings includes a first board and a second board, and further includes:
[0008] Auxiliary mechanisms are used to improve the stability of the connection;
[0009] The first plate has two first holes on its top outer wall, and studs are inserted into the holes. One end of the stud is connected to a block, and a connecting rod is connected to one side outer wall of the block. One end of the connecting rod is connected to a ball. The second plate has two second holes on one side outer wall, and mounting cylinders are inserted into the holes. The mounting cylinders have cavities inside, and four equally spaced protrusions are installed on the top inner wall of the mounting cylinder. A fixing block is installed at the center of the top inner wall of the mounting cylinder. Four clamping blocks are equally spaced on the outer wall of the fixing block via a rotating shaft. A mounting block is connected to one side outer wall of each clamping block, and a return spring is connected between the protrusions and the mounting blocks.
[0010] In this design, the first and second holes are pre-drilled during the production of the first and second boards. During furniture installation, studs, connecting rods, and balls are fixed to the first board through the first hole, and an installation cylinder is fixed to the second board through the second hole. The connecting rod and ball are then inserted into the installation cylinder, which compresses the clamping block. The clamping block tilts outward, allowing the ball to continue to extend. Finally, under the action of the return spring, the clamping block and fixing block wrap around and fix the ball, thus completing the alignment and connection of the first and second boards. Installation is convenient and quick, which helps to improve installation efficiency. At the same time, the components are covered and not exposed, ensuring the overall design aesthetics of the wood and making it more beautiful.
[0011] In a preferred embodiment, the auxiliary mechanism includes a thread on the outer wall of the mounting cylinder, and a square groove is formed on the inner wall of the mounting cylinder. Both the block and the square groove are hexagonal in shape, and the size of the block and the square groove correspond to each other.
[0012] The thread can improve the installation stability of the mounting cylinder. After the ball or other object is inserted into the mounting cylinder, the hexagonal block and the hexagonal groove fit together, which can improve the stability of the ball or other object. At the same time, the hexagonal block can be used with the installation tool to facilitate the installation of the ball or other object into the first hole on the first plate.
[0013] As can be seen from the above, a limiting alignment structure for the concealed connection of furniture fittings includes a first board and a second board, and also includes:
[0014] Auxiliary mechanisms are used to improve the stability of the connection;
[0015] The first board has two first holes on its top outer wall, into which studs are inserted. One end of each stud is connected to a block, and a connecting rod is connected to one side of the block's outer wall. One end of the connecting rod is connected to a ball. The second board has two second holes on one side outer wall, into which mounting cylinders are inserted. The mounting cylinders have internal cavities, and four equally spaced protrusions are mounted on the top inner wall of the mounting cylinder. A fixing block is mounted at the center of the top inner wall of the mounting cylinder. Four clamping blocks are equally spaced on the outer wall of the fixing block via a pivot, and a mounting block is connected to one side of each clamping block's outer wall. A return spring connects the protrusions and the mounting blocks. The limiting alignment structure for concealed connection of furniture accessories provided by this utility model has the technical advantages of convenient installation and aesthetic appeal.

Obviously, the described embodiments are only some embodiments of this application, and not all embodiments. The components of the embodiments of this application described and marked in the accompanying drawings can be arranged and designed in various different configurations. Therefore, the following detailed description of the embodiments of this application provided in the accompanying drawings is not intended to limit the scope of the claimed application, but merely represents selected embodiments of this application.

[0023] The present invention discloses a limiting alignment structure for invisible connection of furniture accessories. It is mainly used in the traditional limiting alignment structure for connecting furniture accessories. The traditional structure usually achieves position fixation through a three-in-one connector. The installation steps are cumbersome and inefficient. Moreover, the screw or nut is exposed on the outer surface of the furniture, which will destroy the overall design of the wood itself and give people a rough and unrefined visual feeling and an unsightly scene.
[0024] Reference Figure 1 , Figure 2 , Figure 3 , Figure 4 and Figure 5 A limiting alignment structure for concealed connection of furniture fittings, comprising a first board 1 and a second board 2, and further comprising:
[0025] Auxiliary mechanisms are used to improve the stability of the connection;
[0026] The top outer wall of the first plate 1 has two first holes, and studs 7 are inserted into the holes. A block 8 is fixedly connected to one end of the stud 7. A connecting rod 9 is fixedly connected to one side outer wall of the block 8. A ball 4 is fixedly connected to one end of the connecting rod 9. The second plate 2 has two second holes on one side outer wall, and an installation cylinder 5 is inserted into the holes. The installation cylinder 5 has a cavity inside. Four equally spaced protrusions 13 are fixedly installed on the top inner wall of the installation cylinder 5. A fixing block 10 is fixedly installed at the center of the top inner wall of the installation cylinder 5. Four clamping blocks 11 are movably installed on the outer wall of the fixing block 10 through a rotating shaft at equal distances. An installation block 12 is fixedly connected to one side outer wall of the clamping block 11. A return spring 14 is fixedly connected between the protrusions 13 and the installation block 12. The position of the studs 7 corresponds to the position of the installation cylinder 5.
[0027] The top of the clamping block 11 is set with a "V" shaped opening structure to facilitate the insertion of the ball, the bottom of the clamping block 11 is set with an arc-shaped structure, and the clamping block 11 is adapted to the ball 4. The top outer wall of the fixing block 10 is set with an arc-shaped concave structure, and the top outer wall of the fixing block 10 is adapted to the ball 4. The clamping block 11 and the fixing block 10 cooperate to clamp the ball 4.
[0028] The cavity is adapted to the connecting rod 9 and the block 8, ensuring that the ball 4 and the connecting rod 9 can enter smoothly and fit together.
[0029] The first hole and the second hole are pre-drilled during the production of the first board 1 and the second board 2, and their positions correspond to each other.
[0030] It should be noted that an outer sleeve with internal and external threads 6 can be added and fixed inside the first hole to fix the stud 7. When disassembling, the stud 7 can be removed, thereby reducing the damage to the first plate 1 when disassembling the stud 7.
[0031] In practical use, during installation, the stud 7 is screwed into the first hole on the first plate 1. A tool can be used to press the mounting cylinder 5 into the second hole on the second plate 2. Then, the connecting rod 9 and the ball 4 are inserted into the mounting cylinder 5. The ball 4 presses against the clamping block 11, causing the clamping block 11 to tilt outward, allowing the ball 4 to continue to extend. Finally, under the action of the return spring 14, the clamping block 11 springs back, thereby the clamping block 11 and the fixing block 10 wrap around and fix the ball 4, completing the alignment and connection of the first plate 1 and the second plate 2. When adjusting or disassembling, the ball 4 can be pulled out forcefully.
[0032] Reference Figure 2 , Figure 3 and Figure 4 In a preferred embodiment, the auxiliary mechanism includes a thread 6 provided on the outer wall of the mounting cylinder 5, and a square groove 3 is also provided on the inner wall of the mounting cylinder 5. Both the block 8 and the square groove 3 are hexagonal structures, and the size of the block 8 and the square groove 3 correspond to each other.
[0033] Specifically, the thread 6 is embedded in the inner wall of the second hole on the second plate 2, which can improve the installation stability of the mounting cylinder 5. After the ball 4 and the like are inserted into the mounting cylinder 5, the hexagonal block 8 and the hexagonal groove 3 fit together and play a certain limiting role, which can improve the stability of the ball 4 and the like. At the same time, the hexagonal block 8 can be used with special installation tools (such as electric wrenches) to facilitate the installation of the ball 4 and the like into the first hole on the first plate 1.
[0034] Working principle: When in use, place one end of a special installation tool (such as an electric wrench) onto the hexagonal block 8, and screw the stud 7 into the first hole on the first plate 1. The tool can be used to press the installation cylinder 5 into the second hole on the second plate 2 to ensure that the installation positions of the block 8 and the square groove 3 correspond. Then, insert the connecting rod 9 and the ball 4 into the installation cylinder 5. The ball 4 presses against the clamping block 11, causing the clamping block 11 to tilt outward, allowing the ball 4 to continue to extend. Finally, under the action of the return spring 14, the clamping block 11 springs back, thereby the clamping block 11 and the fixing block 10 wrap around and fix the ball 4. The hexagonal block 8 and the hexagonal square groove 3 fit together, completing the alignment and connection of the first plate 1 and the second plate 2. When adjusting or disassembling, simply pull out the ball 4.
[0035] The above description is merely a preferred embodiment of this utility model, but the protection scope of this utility model is not limited thereto. The substitutions may be replacements of some structures, devices, or method steps, or they may be complete technical solutions. Equivalent substitutions or modifications made based on the technical solution and inventive concept of this utility model should all be covered within the protection scope of this utility model.
