Detailed Description
The preferred embodiments of the present invention will be described in conjunction with the accompanying drawings, and it will be understood that they are presented herein only to illustrate and explain the present invention, and not to limit the present invention.
Referring to fig. 1, a hidden furniture connecting device includes:
the screw pin rod 10 is of a cylindrical rod-shaped structure, and the outer peripheral surfaces of two ends of the screw pin rod are provided with screw clamping grooves 11;
the locking sleeve 20 is sleeved at two ends of the threaded pin rod 10, the inner circumferential surface of the locking sleeve 20 is clamped with the threaded pin rod 10, the outer circumferential surface of the locking sleeve 20 is clamped with the furniture plate 30, and the locking sleeve 20 is divided into a sleeving part 21 and a clamping claw part 22;
the sleeve joint part 21 is a cylindrical annular structure;
the claw part 22 is fixedly connected to the annular end part of the sleeve part 21, and the claw part 22 is divided into an inner claw 22a and an outer claw 22 b.
The working principle of the technical scheme is as follows: the furniture jointing device provided by the embodiment is used for jointing the furniture plates, and the operation process comprises the steps of firstly drilling mounting holes with the diameter slightly larger than that of the threaded pin rod 10 on two furniture plates to be jointed and connected respectively, placing a lock sleeve 20 in each mounting hole, and then inserting the threaded pin rod 10 into the mounting holes. In the process of inserting the threaded pin rod 10, the inner clamping jaw 22a on the lock sleeve 20 is clamped with the threaded clamping groove 11, and meanwhile, the outer clamping jaw 22b is pushed outwards and expanded outwards in the process of inserting the threaded pin rod 10, so that the outer clamping jaw 22b is clamped into the side wall of the mounting hole, the outer clamping jaw 22b can play a role of a barb, and the whole lock sleeve 20 is connected into the wooden furniture board 30.
The beneficial effects of the above technical scheme are that: the lock sleeve 20 with a specific structure is locked and fixed in a furniture board, the threaded pin rod 10 is relatively fixed on the lock sleeve 20 through the matching of the inner clamping jaw 22a and the threaded clamping groove 11, and the threaded pin rod 10 can only enter out due to the unidirectional clamping structure of the inner clamping jaw 22a and the threaded clamping groove 11. After the furniture jointing device with the structure is connected, no hole site can be seen on the surface of the board, so that the furniture jointing device is attractive and durable; and the threaded pin rod 10 and the lock sleeve 20 of the mutually-locked structure ensure that the connection between the furniture plates is more stable.
As an embodiment of the present invention, referring to fig. 3 and 4,
the cross section of the inner clamping jaw 22a is in a shape of a straight line, one end of the inner clamping jaw is fixedly connected with the sleeving part 21, and the other end of the inner clamping jaw is a free end and is arranged in an inward inclined manner;
the cross section of the outer clamping jaw 22b is L-shaped, one end of the outer clamping jaw is fixedly connected with the sleeving part 21, and the other end of the outer clamping jaw is a free end and is arranged obliquely outwards.
The number of the inner claws 22a is three, the number of the outer claws 22b is three, and the inner claws 22a and the outer claws 22b are uniformly distributed on the cross section of the sleeve joint part 21.
The working principle and the beneficial effects of the technical scheme are as follows: the inner jaw 22a and the outer jaw 22b may be made of elastic metal material, and the inner jaw 22a gathers toward the central axis of the socket portion 21, so that the in-line shaped inner jaw 22a is engaged with the thread engaging groove 11. One side of the L-shaped outer jaw 22b is also gathered toward the central axis of the socket part 21, and the other side is directed outward, so that the outer jaw 22b is pushed outward when the screw pin 10 is inserted, and the free end of the outer jaw 22b is hooked into the sidewall of the mounting hole, thereby firmly locking the lock sleeve 20 in the furniture plate.
