Detailed Description

The present invention will be further described with reference to the drawings attached to the specification, but the present invention is not limited to the following embodiments.

As shown in fig. 1, the anti-theft integral lock core comprises an inner shell 1, a lock core structure and two swing parts. The lock core structure and the swing part structure are arranged in the inner shell, the lock core structure is arranged in the center of the inner shell, and the two swing part structures are used for being matched with the lock core structure and are symmetrically arranged on two sides of the lock core structure.

The center of inner shell is equipped with first inner chamber 11, and the bilateral symmetry of first inner chamber sets up two second inner chambers 12, and lock core structure installs in first inner chamber, and the goods of furniture for display rather than for use structure installs in the second inner chamber. The first inner cavity is a cylindrical cavity, an opening 13 (facilitating installation of the lock cylinder structure) is formed in the top of the first inner cavity, and a bayonet 14 is formed in the upper portion of the inner wall of the first inner cavity. And a swing arm groove 17 is arranged between the first inner cavity and the second inner cavity, extends upwards to the top of the first inner cavity and is communicated with the opening of the first inner cavity.

Be equipped with pivot seat 15 on the second inner chamber, the top of pivot seat all opens (the installation of convenient goods of furniture for display rather than for use structure) with the top of second inner chamber, and the bottom of second inner chamber is equipped with spout 16 (guide steel ball motion), and the spout is the arc bending. The bottom of the second chamber (the bottom of the chute) and the outside (the side facing the first chamber) are provided with a rocker slot 18 communicating therewith.

The lock core structure comprises a steel cap 2, a three-ball seat 4, a lock core spring cover 5 and a spring 6 which are sequentially arranged from top to bottom. The steel cap is fixed at the top of the first inner cavity, the edge of the steel cap is embedded into the bayonet, and the upper portion of the steel cap is exposed out of the inner shell. The three-ball seat and the lock cylinder spring cover are vertically and slidably positioned in the first inner cavity. The top of the three-ball seat is provided with three steel balls 3, and the bottom surface of the three-ball seat is vertically fixed with a guide column 4.1. The three-ball seat is made of plastic, so that the cost is low, the problem that the lock is unlocked by using a strong unlocking device can be effectively solved, and meanwhile, the steel balls can be easily pressed into the three-ball seat, so that the installation of a lock cylinder structure is facilitated. The lock cylinder spring cover is provided with a guide hole 5.1, the inner diameter of the guide hole is matched with the outer diameter of the guide column, and the guide column extends into the guide hole, so that the three ball seats are ensured to be kept in a vertical state in the movement process. The spring is arranged below the lock cylinder spring cover and used for pushing the lock cylinder spring cover upwards.

The swing structure comprises a swing part 7, a steel ball 8 and a swing arm 9. The swing piece can be positioned in the second inner cavity in a swinging mode, rotating shafts 7.1 (shown in figure 12) are arranged on the left side and the right side of the top of the swing piece, the rotating shafts are installed in the rotating shaft seats, notches 7.2 are formed in the bottom of the swing piece, baffles 7.3 (shown in figure 11) extending downwards are arranged on the left sides of the notches, steel balls are placed in the notches and positioned between the notches and the sliding grooves, the swing arms are perpendicularly fixed on the right side of the swing piece (shown in figure 11), and the swing arms penetrate through the swing piece grooves and extend into the space between the three ball seats of the first inner. In the two swinging parts, swinging axes of the swinging parts are parallel to each other and are also perpendicular to the sliding direction of the three ball seats and the lock cylinder spring cover.

In order to ensure the smooth swing of the swing part, the steel ball is prevented from being clamped between the swing part and the inner shell, a certain gap is required to be kept between the notch and the steel ball, and the steel ball can move freely. And when the rocker portion is deployed (fig. 4), a portion of the rocker portion extends through the rocker slot and out of the interior housing.

As shown in fig. 12, two branches are formed on the swing arm, a bump 9.1 is arranged at the front end of each branch, the swing arm applies force to the three ball seats above and the lock cylinder spring cover below through the bumps, and a gap 9.2 which is suitable for the appearance of the guide post is arranged between the branches. And through holes for inserting the nail rods are further formed in the steel cap and the tee seat.

The utility model discloses an assembly step does: the spring and the lock cylinder spring cover are sequentially placed into the first inner cavity, the steel ball and the swing piece are sequentially placed into the second inner cavity, the three ball seats are placed, and finally the steel cap is pressed to fix all the components in the inner shell.

The utility model discloses can directly pack into among the security label, and conventional lock core needs install one by one for speed of production greatly. Because the open design of pivot seat, still need utilize security tags's casing to carry on spacingly to the top of goods of furniture for display rather than for use pivot to swing as the center all the time for the goods of furniture for display rather than for use to make the motion process more stable.

The utility model discloses can install in the security label of various structures:

embodiment 1 (shown in fig. 17 and 18) is an integrated anti-theft tag, which comprises a base 21 and a rotating arm 22 rotatably hinged on the base, wherein an anti-theft integrated lock cylinder is installed in the base, a nail rod is installed on the rotating arm, the matching position of the nail rod and the anti-theft integrated lock cylinder is determined in advance, and the anti-theft integrated lock cylinder can be locked only by pressing with hands, so that the anti-theft tag is very convenient to use, and the working efficiency is improved;

embodiment 2 (shown in fig. 19) is split type anti-theft label, including base 21 and nail cap 23, and the whole lock core of theftproof is installed in the base, and the nail pole is installed on the nail cap, because base and nail cap complete separation, therefore simple structure, small in size.

The utility model discloses a theory of operation is:

when locking, the nail rod 20 is inserted into the lock core structure, the spring upwards pushes the swing arm through the lock core spring cover, the swing arm then upwards pushes the three ball seats, as the inner wall of the steel cap has a certain inclination, the three steel balls are forced to be close to the center so as to tightly wrap the nail rod, and the swing part keeps a vertical position and leans against two sides of the lock core structure together with the steel balls; when a person tries to forcibly knock off the anti-theft tag by using external force, the three ball seats are propped by the swing piece and cannot move downwards as the swing piece is clamped below the three ball seats, so that accidental unlocking caused by the fact that the steel balls are separated from the nail rod is avoided;

when needing to take out commodity, put the security label on the magnetic force unlocking device, the magnetic force unlocking device produces suction (shown by the arrow in figure 4) to steel ball and steel ball respectively, the steel ball receives behind the suction along the spout toward controlling both sides motion, the goods of furniture for display rather than for use then swings certain angle and keeps away from the lock core structure under the steel ball drives, the swing arm is downward roof pressure lock core spring cap again, thereby the steel ball receives and drives three ball seats downstream behind the suction and break away from the steel cap extrusion, directly extract the nail pole this moment and just can realize unblanking.
