[0028] Embodiment 1:

[0029] See also Figure 1-4 The utility model describes the above technical solution in detail through the following embodiments:

[0030] An intelligent locking type furniture panel connector, comprising:

[0031] A connecting rod 1, the connecting rod 1 comprises an insert rod 11, a clamping assembly is provided at the top of the insert rod 11, the clamping assembly is used to connect with the eccentric wheel, a connecting rod fixing piece 2 is provided at the bottom of the insert rod 11, and a recovery assembly 3 is provided outside the connecting rod fixing piece 2;

[0032] The insert rod 11 is made of metal, and the outer diameter of the insert rod 11 should be the same as the inner diameter of the plate mounting hole. The eccentric wheel is a well-known eccentric wheel of a plate connecting piece, which is not shown in the figure.

[0033] The clamping assembly comprises a pull rod 12 , the bottom end of the pull rod 12 is connected to the insertion rod 11 , the top end of the pull rod 12 is provided with a clamping joint 13 , and the top of the clamping joint 13 is provided with a cross groove 14 .

[0034] The pull rod 12, the insert rod 11 and the clamping joint 13 are integrally formed of metal materials. The cross slot 14 is used for inserting the head of a cross screwdriver.

[0035] The connecting rod fixing member 2 includes a fixing column 21 , which is fixedly mounted on the bottom end of the insertion rod 11 , and four sawtooth plates 24 are evenly and slidably mounted on the side of the fixing column 21 , and a fixing spring 27 is provided between two opposite sawtooth plates 24 .

[0036] The fixing column 21 and the insertion rod 11 are integrally formed with the same material, and the outer diameter of the fixing column 21 is smaller than the outer diameter of the insertion rod 11. The fixing spring 27 is used to make the top serrated plate 24 contact with the plate, and fix the connecting rod 1 by friction.

[0037] Two through holes 23 are formed through the fixed column 21 . The two through holes 23 are perpendicular to each other and do not communicate with each other. Active holes 22 are perpendicularly formed on both sides of the through holes 23 . Fixed springs 27 are slidably installed in the active holes 22 .

[0038] There are two fixed springs 27, and the axes of the two fixed springs 27 are perpendicular to each other. The movable hole 22 and the through hole 23 are processed by a drill.

[0039] Two guide posts 26 are welded to the inner side of the serrated plate 24 , one of the guide posts 26 is inserted into the movable hole 22 , and the other guide post 26 is inserted into the through hole 23 and abuts against the end surface of the fixed spring 27 .

[0040] The guide post 26 can slide along the movable hole 22 and the through hole 23. The two ends of the fixed spring 27 are respectively against the end faces of the guide post 26 of two different sawtooth plates 24. Under the elastic force of the fixed spring 27, the guide post 26 slides outside the through hole 23, thereby driving the sawtooth plate 24 to slide outward until the sawtooth plate 24 is blocked.

[0041] A clamping tooth 25 is disposed on the outer side of the sawtooth plate 24. The clamping tooth 25 is inclined upward, and the outer edge of the sawtooth plate 24 is arc-shaped.

[0042] The engaging teeth 25 and the sawtooth plate 24 are integrally formed of metal material. Since the engaging teeth 25 are inclined upward, when the engaging teeth 25 contact the wall of the plate installation hole, the sawtooth plate 24 can be prevented from moving outside the plate installation hole.

[0043] The recovery component 3 includes a base plate 31, the outer diameter of the base plate 31 is the same as the outer diameter of the insertion rod 11, and a plurality of storage grooves 34 are evenly arranged on the top surface of the base plate 31. A clamping plate 36 is provided on the top of the storage groove 34, and the clamping plate 36 is clamped with the fixing component. The serrated plate 24 can be stored in the storage groove 34 by rotating the connecting rod fixing part 2.

[0044] The recovery component 3 is integrally formed of nylon material. The width of the clamping plate 36 is the same as the thickness of the serrated plate 24. The outer diameter of the bottom plate 31 is the same as the outer diameter of the insertion rod 11. A plug hole 32 is provided through the center of the bottom plate 31. The inner diameter of the plug hole 32 is the same as the outer diameter of the fixed column 21. The bottom of the fixed column 21 can rotate in the plug hole 32. A plurality of second serrations 33 are evenly provided on the bottom surface of the bottom plate 31. The second serrations 33 are used to contact the bottom surface of the plate mounting hole to provide friction, thereby limiting the rotation of the bottom plate 31. The outer diameter of the storage groove 34 is the same as the outer diameter of the bottom plate 31. The number of storage grooves 34 is the same as the number of serrated plates 24.

[0045] In the unmounted state, the engaging teeth 25 abut against the inner wall of the receiving groove 34 . At this time, the fixing spring 27 is compressed by the guide post 26 .

[0046] A contact groove 37 is provided between the receiving grooves 34 , and the width of the contact groove 37 is the same as the width of the serrated plate 24 .

[0047] The contact groove 37 is the space between two adjacent receiving grooves 34 .

[0048] In the installed state, rotating the connecting rod 1 clockwise can drive the fixed column 21 to rotate, thereby driving the serrated plate 24 to rotate through the guide column 26. Since the second serration 33 contacts the bottom surface of the plate mounting hole, the bottom plate 31 cannot rotate, and then the serrated plate 24 rotates from the receiving groove 34 to the contact groove 37, and the engaging tooth 25 loses the obstruction of the receiving groove 34, so that the serrated plate 24 loses the pressure on the fixing spring 27. Under the elastic force of the fixing spring 27, the serrated plate 24 moves outward until the engaging tooth 25 abuts against the wall of the plate mounting hole.

[0049] A sliding slope 35 is provided on one side of the receiving groove 34 close to the contact groove 37 , and the edge of the sliding slope 35 is flush with the side surface of the bottom plate 31 .

[0050] Rotating the connecting rod 1 counterclockwise can drive the fixed column 21 to rotate counterclockwise, thereby driving the serrated plate 24 to rotate toward the receiving groove 34 through the guide column 26. Since the outer edge of the serrated plate 24 is arc-shaped, and the receiving groove 34 is provided with a sliding inclined surface 35 on the side close to the contact groove 37, when the serrated plate 24 rotates toward the receiving groove 34, the outer edge of the serrated plate 24 contacts the sliding inclined surface 35, and the serrated plate 24 moves toward the fixed column 21, and the guide column 26 compresses the fixed spring 27 until the serrated plate 24 is received in the receiving groove 34.

[0051] At this time, an axial pulling force is applied to the connecting rod 1, which can drive the connecting rod 1 to move outside the plate mounting hole. Since the serrated plate 24 is received by the receiving groove 34, the snap-on teeth 25 no longer contact the mounting hole wall and will not block the fixing column 21 from moving outward. Therefore, the fixing column 21 will move outward with the connecting rod 1, thereby driving the serrated plate 24 to move outside the mounting hole through the guide column 26, and then driving the recovery component 3 as a whole to move outside the mounting hole through the snap-on plate 36 to achieve dismantling.

[0052] When using the device, the operator of this embodiment aligns the bottom plate 31 with the mounting hole of the plate, inserts the connecting piece into the mounting hole, and ensures that the axis of the connecting rod 1 coincides with the axis of the mounting hole, until the bottom surface of the bottom plate 31 contacts the bottom surface of the mounting hole.

[0053] Insert the screwdriver head into the cross slot 14 and rotate the screwdriver clockwise to drive the connecting rod 1 to rotate clockwise through the cross slot 14 .

[0054] The connecting rod 1 rotates clockwise, which can drive the fixing column 21 to rotate clockwise, thereby driving the serrated plate 24 to rotate through the guide column 26. Since the second serration 33 contacts the bottom surface of the plate mounting hole, the bottom plate 31 cannot rotate, and then the serrated plate 24 rotates from the receiving groove 34 to the contact groove 37, and the engaging tooth 25 loses the obstruction of the receiving groove 34, so that the serrated plate 24 loses the pressure on the fixing spring 27. Under the elastic force of the fixing spring 27, the serrated plate 24 moves outward until the engaging tooth 25 abuts against the wall of the plate mounting hole.

[0055] Since the engaging teeth 25 are inclined upward, when the engaging teeth 25 are in contact with the wall of the plate installation hole, the serrated plate 24 can be prevented from moving to the outside of the plate installation hole.

[0056] The clamping joint 13 and part of the insertion rod 11 are inserted into the mounting hole of another plate, and then the clamping joint 13 and the pull rod 12 can be clamped by the eccentric wheel to achieve the connection of the two plates.

[0057] When disassembly is required, first turn the eccentric wheel to release the connection between the two plates.

[0058] Then insert the screwdriver head into the cross slot 14 , and rotate the screwdriver counterclockwise to drive the connecting rod 1 to rotate counterclockwise through the cross slot 14 .

[0059] The connecting rod 1 rotates counterclockwise to drive the fixed column 21 to rotate counterclockwise, thereby driving the serrated plate 24 to rotate toward the receiving groove 34 through the guide column 26. Since the outer edge of the serrated plate 24 is arc-shaped, and the receiving groove 34 is provided with a sliding inclined surface 35 on the side close to the contact groove 37, when the serrated plate 24 rotates toward the receiving groove 34, the outer edge of the serrated plate 24 contacts the sliding inclined surface 35, and the serrated plate 24 moves toward the fixed column 21, and the guide column 26 compresses the fixed spring 27 until the serrated plate 24 is received in the receiving groove 34.

[0060] At this time, an axial pulling force is applied to the connecting rod 1, which can drive the connecting rod 1 to move outside the plate mounting hole. Since the serrated plate 24 is received by the receiving groove 34, the snap-on teeth 25 no longer contact the mounting hole wall and will not block the fixing column 21 from moving outward. Therefore, the fixing column 21 will move outward with the connecting rod 1, thereby driving the serrated plate 24 to move outside the mounting hole through the guide column 26, and then driving the recovery component 3 as a whole to move outside the mounting hole through the snap-on plate 36 to achieve dismantling.
