Detailed Description
Further description will be given below of embodiments shown in the drawings.
In the anti-theft device of the electronic screen price tag shown in the attached drawing: the front surface of the back splint shell 12 is fixedly connected with the electronic screen price tag (the connection mode is a conventional plug-in structure); the back clip cover 10 is hinged (a hinge shaft 11) on the back of the back clip shell in a swinging way (the swinging axis is horizontally arranged) and can be in cohesion fit with the shelf hook 8; the slidable push rod 3 is used for locking the back clamp cover in the clasping state; the lock core controls the opening and closing states of the push rod.
The connecting end of the shelf hook is T-shaped and is formed by transversely welding a short rod 8-1 at the end part of the shelf hook; the back clamp cover is provided with a caulking groove 10-3 which is suitable for the rod piece part of the shelf hook (the rod piece part can be embedded in the caulking groove) and penetrates through the outer side (the upper side in fig. 3) edge of the swinging end; the back clip cover is also formed with a transverse slot 10-2 on its inner side which is adapted to the short bar (shown in the figure as being horizontally disposed) and which is perpendicular to the insertion slot.
The back of the back clamp shell is provided with a slideway with a sliding direction parallel to the swing axis of the back clamp cover, and the push rod is slidably positioned in the slideway and is subjected to the pushing force applied by the push rod spring 2 towards the right direction; one side of the push rod (the lower side edge is visible in fig. 3) is provided with a stop block 3-1; the stop block is interfered with the swing track of the back clamp cover along the moving track of the push rod, so that the stop block can prevent the back clamp cover from swinging towards the opening direction when in a locking state (the push rod is locked again after the back clamp cover is closed, and the stop block can stop the back clamp cover from opening).
Further, a gap 3-2 (the width of the left side stop block is smaller than that of the right side stop block) is formed in the middle of the stop block, and the width of the gap is larger than that of a spigot 10-1 at the upper edge of the back clamp cover (the width of the spigot at the two sides of the caulking groove is equal); the figure can be seen: the distance between the two rabbets positioned on the two sides of the caulking groove is larger than the width of the left stop block; therefore, the back clamp cover can swing and open after the push rod only moves for a certain distance (at the moment, the left stop block is positioned between the two rabbets, the right rabbet is positioned at the notch, and interference factors are eliminated between the push rod and the back clamp cover).
The lock cylinder comprises a lock head 5 slidably positioned in a lock head slide at the back of the back clamp housing, and a lock head spring 6 for applying a top pressure (downward top pressure in fig. 1) to the lock head; the sliding direction of the lock head is vertical to the sliding direction of the push rod; the top end of the lock head also stretches into the slideway and is matched with two grooves (a first groove 3-3 and a second groove 3-4) on the side surface of the push rod respectively, so that the push rod is in a locking state or an opening state.
The lock head is an iron element which can act with the magnetic unlocking device.
The working principle of the invention is as follows:
1. locked state (see FIG. 1)
At this time, the back clip cover is wrapped around the short rod at the end of the shelf hook and rotates to the locking position, the push rod is retracted (the push rod can be manually pushed to retract) to the locking position, the stop block on the push rod stops the back clip cover to keep the back clip cover in a locking state, and the lock head is pressed in the second groove of the push rod under the action of the lock head spring to lock the push rod to prevent the push rod from moving.
2. Opening process
When the lock needs to be opened, the magnetic unlocking device is only required to be placed on the lock cylinder at the back of the back clamp shell, and the lock head is acted by magnetic force and moves upwards against the spring pressure of the lock head so as to be separated from the second groove of the push rod; at this time, the push rod spring 2 applies a pushing force to the push rod to force the push rod to move towards the right direction, so that the stop block of the push rod and the spigot of the back clamp cover are just in an interference elimination state (at this time, the lock head is in pushing fit with the first groove of the push rod); therefore, the shelf hook and the back clip shell can be separated only by lightly opening the back clip cover by hands.
2. Locking process
The rod piece part of the goods shelf hook is embedded into the caulking groove of the back clamp cover, the short rod at the end part of the goods shelf hook is placed in the transverse groove at the inner side surface of the back clamp cover, then the back clamp cover is gently pulled to be in a locking state, and then the push rod is gently pushed inwards by hands until the push rod moves to the position where the second groove is in press fit with the lock head, and the goods shelf hook and the back clamp shell are in the locking position (the positions of all parts are shown in step 1).
