DETAILED DESCRIPTION

[0048] In order to enable those skilled in the art to better understand the scheme of the present invention, the technical scheme in the embodiments of the present invention will be clearly and completely described below in conjunction with the drawings in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without creative work should fall within the scope of protection of the present invention.

[0049] like Figure 1-Figure 14As shown, a hidden furniture connection structure is arranged between a first plate body 1 and a second plate body 2, and is used to hide the first plate body 1 and the second plate body 2 of the furniture. The first plate body 1 and the second plate body 2 are wooden boards. The hidden furniture connection structure includes a fixing seat 4 and a limiting component 5.

[0050] The fixing seat 4 is a hollow cylindrical structure made of metal material, and its interior is hollow to form a receiving cavity 41. The fixing seat 4 is connected to the first plate body 1. In this embodiment, the outer wall of the fixing seat 4 and the connecting part of the first plate body 1 form a threaded structure, thereby increasing the stability of its connection with the first plate body 1. At the same time, by applying external force to rotate the fixing seat 4, it can be firmly assembled into the first plate body 1, which is convenient for installation. The fixing seat 4 is inserted into the first plate body 1 as a whole, that is, the entire length direction of the fixing seat 4 is hidden in the first plate body 1.

[0051] The limit assembly 5 is connected to the second plate body 2, and includes a base 6 made of metal material, and an elastic locking unit 7 assembled in the base 6. The elastic locking unit 7 includes a movable part 71 made of metal material, and a switch part 72 arranged in linkage with the movable part 71. The linkage arrangement here means that when the switch part 72 moves, the movable part 71 can also move synchronously. The base 6 is a hollow cylindrical structure, and the outer wall of the base 6 is connected to the second plate body 2 with a threaded structure, and the part is firmly connected to the second plate body 2; most of the outer wall of the base 6 is a smooth structure, which is exposed outside the second plate body 2, and can be axially extended into the accommodating cavity 41 of the fixed seat 4, and the base 6 is formed with a slot 61 extending along the axial direction, and part of the movable part 71 and the switch part 72 can extend from the slot 61.

[0052] The movable member 71 has a locking position and an unlocking position. When in the locking position, part of the movable member 71 extends from the slot 61 and can abut against the fixed seat 4 sleeved outside the base 6. Figure 8 , Fig. 9 As shown, at this time, the movable member 71 abuts against the inner wall of the fixing seat 4, and the two achieve a stable installation state, that is, the base 6 and the fixing seat 4 are fixedly connected, thereby achieving a fixed assembly connection between the first plate body 1 and the second plate body 2.

[0053] When in the unlocked position, the movable member 71 retracts into the base 6, that is, the movable member 71 is out of contact with the inner wall of the fixed seat 4, so that the base 6 and the fixed seat 4 can move freely, thereby realizing the disassembly of the first plate body 1 and the second plate body 2.

[0054] The switching of the movable member 71 from the locked position to the unlocked position is achieved by pressing the switch member 72. Specifically, the switch member 72 extends from the slot 61. It should be noted that the switch member 72 may extend from the slot 61 as a whole, or may not extend from the slot 61 completely, but may be partially in the slot 61, as long as it can drive the movable member 71 to switch from the locked position to the unlocked position under the action of the disassembly tool 8. The switch member 72 has a plane extending along the axial direction of the base 6, which at least partially corresponds to the joint 3 of the first plate body 1 and the second plate body 2. Applying an external force to drive the switch member 72 to expand and contract relative to the slot 61 can drive the movable member 71 to switch from the locked position to the unlocked position. Since the switch member 72 corresponds to the joint 3 of the first plate body 1 and the second plate body 2, and the joint 3 is a slit structure, even if the first plate body 1 and the second plate body 2 are firmly connected, the thinner disassembly tool 8 can also extend into the slit-shaped joint 3 to compress the switch member 72. In other words, after the fixing seat 4 and the limiting assembly 5 are connected, they are completely hidden between the first plate body 1 and the second plate body 2, and the first plate body 1 and the second plate body 2 realize a truly hidden connection, and are easy to disassemble and can be repeatedly assembled and disassembled.

[0055] like Figure 7 , Fig.11 , Fig.13 As shown, in order to realize the automatic reset of the movable member 71, the elastic locking unit 7 also includes a reset member 73 that abuts against the movable member 71. The movable member 71 is rotatably connected to the base 6 via a rotating shaft 74, and includes a body 711 connected to the rotating shaft 74, and a locking portion 712 that can extend from the slot 71, and the movable member 71 abuts against the inner wall of the fixed seat 4 through the locking portion 712. The locking portion 712 has an arc-shaped guide surface 713 that can abut against the fixed seat 41, and a stepped surface 714 located at the terminal of the arc-shaped guide surface 713 for locking the fixed seat 4. Specifically, when the fixing seat 4 is sleeved onto the outside of the base 6, the inner wall of the fixing seat 4 presses against the arc-shaped guide surface 713 and slides axially relative to the base 6 until the locking portion 712 completely falls into the accommodating cavity 41 of the fixing seat 4. At this time, the step surface 714 firmly presses against the inner wall of the fixing seat 4. Even under the action of external force, the fixing seat 4 can continue to slide downward relative to the base 6, but it cannot slide upward relative to the base 6. Therefore, under the action of the limiting component 5, the base 6 and the fixing seat 4 are firmly assembled and connected.

[0056] like Figure 7 As shown, in this embodiment, the movable member 71 and the switch member 72 are integrally arranged, the movable member 71 is a flat plate structure, and the switch member 72 and the lock portion 712 are arranged at both ends of one side of the body 711. In order to facilitate the assembly of the reset member 73, a support portion 715 for limiting the sleeve of the reset member 73 is provided on the body 711, and the support portion 715 is arranged opposite to the switch member 72. Fig. 9Taking the direction shown as an example, the lock portion 712 and the switch member 72 are both located on the right side of the body 711, and both are arranged at the upper and lower ends, and the support portion 715 and the switch member 72 are located at the relative positions on the left and right sides of the body 711. A positioning surface 716 is also provided at the upper left side of the body 711 and at a position opposite to the arc-shaped guide surface 713, which is used to limit the rotation angle of the movable member 71 relative to the base 6 to prevent the movable member 71 from excessively rotating.

[0057] When the elastic locking unit 7 and the base 6 are assembled, the main body 711 and the reset member 73 are completely located in the base 6, one end of the reset member 73 is in contact with the inner wall of the fixed base 4, the rotating shaft 74 is arranged in the radial direction of the base 6, the plane where the slot 61 is located is perpendicular to the rotating shaft 74, the locking portion 712 protrudes from the slot 61, and the switch member 72 extends from the slot 61. Due to the setting of the positioning surface 716, under the drive of the reset member 73, the positioning surface 716 can be in contact with the inner wall of the fixed base 6, and the movable member 71 will not rotate counterclockwise significantly under the action of the reset member 73.

[0058] When the fixing seat 4 is inserted downward into the outside of the base 6, the fixing seat 4 first slides against the arc-shaped guide surface 713. At this time, the movable member 71 is driven to rotate clockwise around the rotating shaft 74. Once the fixing seat 4 slides down to abut against the upper surface of the switch member 72, the fixing seat 4 stops sliding down, and under the action of the reset member 73, the stepped surface 714 is firmly abutted against the inner surface of the fixing seat 4. At this time, the fixing seat 4 cannot be separated from the base 6 upward under the action of the locking portion 712, thereby realizing the stable assembly of the first plate body 1 and the second plate body 2, and the fixing seat 4 does not completely cover the entire axial direction of the base 6.

[0059] Applying external force to compress the switch member 72 to the left side compresses the reset member 73 and drives the movable member 71 to rotate clockwise around the rotation shaft 74. At this time, the step surface 714 shrinks inward and detaches from the inner wall of the fixed seat 4, so that the fixed seat 4 can move freely relative to the base 6, that is, the first plate body 1 and the second plate body 2 can be disassembled. Since the switch member 72 and the lock portion 712 are located at the upper and lower ends of the body 711, and the rotation shaft 74 is arranged close to the lock portion 712, it does not require a large external force to drive the rotation of the movable member 71 through the switch member 72, and under the restriction of the positioning surface 716, the range of movement of the lock portion 712 will not be too large, and the locking force on the fixed seat 4 is relatively large, ensuring that the connection between the fixed seat 4 and the base 6 is stable and effective.

[0060] In order to limit the shaking of the movable member 71, the width of the slot 61 is equivalent to the thickness of the movable member 71. In order to facilitate the installation of the reset member 73, a circular structure is formed at the bottom of the slot 61 to facilitate the insertion of the reset spring.

[0061] like Figure 1-Figure 4As shown, a hidden furniture connecting plate combination includes a first plate body 1, a second plate body 2, and the above-mentioned hidden furniture connecting structure. The fixing seat 4 is inserted into the first plate body 1 from the side surface in the thickness direction of the first plate body 1 and along the width direction of the first plate body 1 as a whole to achieve fixed assembly of the two.

[0062] The first plate body 1 is formed with a first avoidance groove 11 at the installation position of the fixing seat 4, which is a concave groove located at the end surface of the first plate body 1 facing the second plate body 2 and at the end of the fixing seat 4, and the inner diameter is larger than the outer diameter of the fixing seat 4; the second plate body 2 is formed with a second avoidance groove 21 at the installation position of the limit assembly 5, which is a concave groove located at the end surface of the second plate body 2 facing the first plate body 1 and at the periphery of the base 6, and at least part of the switch member 72 is located in the second avoidance groove 21. When the first plate body 1 and the second plate body 2 are assembled and connected, the first avoidance groove 11 and the second avoidance groove 21 are oppositely spliced, and the switch member 72 is entirely located in the first avoidance groove 11 and the second avoidance groove 12, so as not to affect the assembly connection between the base 6 and the fixing seat 4, and at the same time, sufficient space is provided for the setting and free movement of the switch member 72, preventing the switch member 72 from being exposed to the outside, and effectively preventing the fixing seat 4 from excessively covering the base 6 so as to press down the switch member 72, ensuring that the switch member 72 can be easily compressed inward.

[0063] The plane where the switch element 72 is located is perpendicular to the joint 3 of the first plate body 1 and the second plate body 2. Figure 2 As shown, when the disassembly sheet 81 extends into the gap at the joint 3 of the first plate body 1 and the second plate body 2 , it needs to be perpendicular to the switch member 72 to ensure that the disassembly sheet 81 can effectively press down the switch member 72 .

[0064] A hidden furniture disassembly and assembly device comprises a first plate body 1, a second plate body 2, the above-mentioned hidden furniture connection structure, and a disassembly and assembly tool 8, wherein the disassembly and assembly tool 8 comprises at least a disassembly and assembly sheet 81 which can be inserted into the gap at the joint of the first plate body 1 and the second plate body 2.

[0065] like Figure 1 , Figure 2 , Fig.15 , Fig.16 As shown, the disassembly tool 8 includes a hand-held portion 84 and a disassembly sheet 81. The hand-held portion 84 includes a first portion 841 that can be pressed against the palm, and a second portion 842 that can be pressed against the fingers, which can be made of plastic or silicone material. The disassembly sheet 81 is made of a thin hard metal sheet.

[0066] like Figure 1 As shown, the disassembly sheet 81 has a notch 82, the opening of the notch 82 faces the second direction, and the direction in which the disassembly sheet 81 is inserted into the gap at the joint 3 of the first plate body 1 and the second plate body 2 is the first direction, and the first direction and the second direction are perpendicular or tend to be perpendicular. Fig.15 , Fig.16 As shown, the notch groove 82 has an unlocking protrusion 83, which is used to compress the switch member 72. At least part of the unlocking protrusion 83 is a horizontal surface, and inclined surfaces are formed at both ends to facilitate squeezing the switch member 72 during movement. The height h of the area in the notch groove 82 where the unlocking protrusion 83 is not provided is substantially equal to the outer diameter of the base 6.

[0067] Figure 1 Taking the direction shown in the figure as an example, when the disassembly sheet 81 is inserted downward (in the first direction) into the gap between the first plate body 1 and the second plate body 2, as shown in the figure, Fig.17 As shown, the disassembly sheet 81 on the right side of the opening of the notch groove 82 presses against the switch member 72 and presses down the switch member 72, and then the disassembly sheet 81 is translated to the right (second direction), so that the base 6 slides as a whole into the notch groove 82. At this time, since the height h of the notch groove 82 is roughly equal to the outer diameter of the base 6, and the unlocking protrusion 83 in the notch groove 82 always keeps the switch member 72 compressed, the movable member 71 of the connecting structure is in the unlocking position. If there is only this set of connecting structures between the first plate body 1 and the second plate body 2, the two can be disassembled; if there is another set of connecting structures between the first plate body 1 and the second plate body 2, another disassembly tool 8 can be used to disassemble and assemble the other set of connecting structures.

[0068] A method for disassembling and assembling concealed furniture comprises the following steps:

[0069] The disassembly sheet 81 of the disassembly tool 8 extends into the gap at the joint 3 of the first plate body 1 and the second plate body 2. Since the disassembly sheet 81 can be a very thin sheet structure, the gap at the joint 3 of the first plate body 1 and the second plate body 2 is very small and the disassembly sheet 81 can also be inserted;

[0070] The disassembly sheet 81 compresses the switch member 72 into the base 6, driving the movable member 71 to rotate relative to the base 6, so that the movable member 71 enters the unlocking position;

[0071] The movable member 71 and the fixed seat 4 are out of contact with each other, so that the base 6 and the fixed seat 4 can move freely;

[0072] The first plate body 1 and the second plate body 2 can be separated by applying an external force.

[0073] In the above, there is only one set of connection structures between the first plate body 1 and the second plate body 2. When there are two sets of connection structures between the two sets of connection structures, the switch members 72 of the two sets of connection structures are oriented in the same direction and are perpendicular to the gap at the joint 3 of the first plate body 1 and the second plate body 2. The disassembly and assembly method includes the following steps:

[0074] The first disassembly sheet 81 of the first disassembly tool 8 extends downwardly along the first direction into the gap at the joint 3 of the first plate body 1 and the second plate body 2;

[0075] The first disassembly sheet 81 compresses the switch member 72 of one set of connection structures downward into the base 6, driving the movable member 71 to rotate relative to the base 6, so that the movable member 71 of the connection structure enters the unlocking position;

[0076] The first disassembly sheet 81 moves rightward along the second direction, so that the notch groove 82 on the first disassembly sheet 81 is slidably sleeved outside the base 6 of the set of connection structures, and after sliding a certain distance, the unlocking protrusion 83 in the notch groove 82 keeps the switch member 72 in a state of being compressed and entering the base 6, so that the movable member 71 and the fixed seat 4 are out of the abutting state, that is, the movable member 71 of the set of connection structures is maintained in the unlocking position, and the base 6 and the fixed seat 4 can move freely;

[0077] The second disassembly sheet extends downwardly along the first direction into the gap 3 at the junction of the first plate body 1 and the second plate body 2;

[0078] The second disassembly sheet compresses the switch member of the other connection structure downward into the base, driving the movable member of the other connection structure to rotate relative to the base, so that the movable member of the connection structure enters the unlocking position, and the movable member of the connection structure and the fixed seat are out of the abutment state, so that the base and the fixed seat of the connection structure can move freely;

[0079] The bases and fixing seats of the two sets of connection structures can move freely;

[0080] The first plate body 1 and the second plate body 2 can be separated by applying an external force.

[0081] The above specific implementation modes are used to explain the present invention rather than to limit the present invention. Any modification and change made to the present invention within the spirit of the present invention and the protection scope of the claims shall fall within the protection scope of the present invention.
