[0025] The present invention will be described in detail below with reference to the accompanying drawings and in combination with embodiments. It should be noted that the embodiments and features in the embodiments of the present invention can be combined with each other without conflict.

[0026] like Figures 1 to 9 In the embodiment of a furniture lock and connection structure of the utility model shown, it includes a locking rod 10 and a positioning assembly 20 that can drive the locking rod 10 to rotate and move along its own axis; a spiral groove 100 is provided on the locking rod 10, and the positioning assembly 20 includes an anti-dropping buckle 21 and a locking bolt 22 threadedly matched with the anti-dropping buckle 21, and the anti-dropping buckle 21 is provided with a first through hole 210 and a second through hole 211 that are vertically connected to each other, and the locking rod 10 is penetrated in the first through hole 210, and the locking bolt 22 is threadedly connected to the second through hole 211 and one end close to the locking rod 10 can be inserted into the spiral groove 100, specifically, the locking bolt 22 is turned so that one end of the locking bolt 22 extends into the spiral groove 100, and because the locking bolt 22 contacts the inner wall surface of the spiral groove 100, the axial movement of the locking bolt 22 allows the locking rod 10 to move along the axis and rotate a certain angle to gradually clamp the two furniture profiles, with a simple structure and convenient installation.

[0027] In one embodiment of the present application, the lock rod 10 includes a lock head 11 and a driving rod 12 fixed to one side of the lock head 11 , and the spiral groove 100 is formed on a side wall of the driving rod 12 .

[0028] In one embodiment of the present application, the lock head 11 is in an oblong shape.

[0029] In one embodiment of the present application, the lock head 11 is circular in shape.

[0030] In one embodiment of the present application, one end of the locking rod 10 passing through the first through hole 210 is abutted against and connected to a return spring 200 .

[0031] In one embodiment of the present application, one end of the locking bolt 22 close to the spiral groove 100 is a semicircular head.

[0032] In one embodiment of the present application, the locking bolt 22 is a hexagon socket bolt.

[0033] In one embodiment of the present application, the rotation angle range of the locking rod 20 is 0°-90°.

[0034] In one embodiment of the present application, the first profile 30 and the second profile 31 are also included. A connecting groove 300 adapted to the lock rod 20 is provided on one side of the first profile 30. The cross-sectional shape of the connecting groove 300 is the same as the cross-sectional shape of the lock head 11, both of which are oblong. A positioning groove 301 for accommodating the anti-drop buckle 21 is provided on the top wall of the second profile 31. A lock buckle mounting block 40 is clamped in the second profile 31. The lock buckle mounting block 40 is provided with a lock rod mounting blind hole 401 and an anti-drop buckle mounting hole 402 that are vertically connected to each other. The through hole 402 is installed, and the end of the reset spring 200 away from the locking rod 20 contacts the inner wall of the locking rod mounting blind hole 401. Specifically, when connecting, by inserting the lock head 11 into the connecting groove 300 and then turning the locking bolt 22, the locking bolt 22 drives the locking rod 10 to move a distance toward the compression reset spring 200 and rotate 90° at the same time, so that the lock head 11 is tightly against the first profile 30, so as to tightly connect the first profile 30 and the second profile 31 together. The structure is simple and the installation is convenient.

[0035] In one embodiment of the present application, the cross-section of the connecting groove 300 is oblong or "T"-shaped. Specifically, when the connecting groove 300 is oblong, the shape of the lock head 11 is oblong; when the connecting groove 300 is T-shaped, the shape of the lock head 11 is circular.
