Description

TECHNICAL FIELD

[0001] The utility model relates to a kind of unlocking device of anti-theft label, specifically is movable combination lock opener. BACKGROUND

[0002] At present, most of the goods for sale in most shopping malls and supermarkets are equipped with two different structures of anti-theft labels (single lock core anti-theft label with three ball structure and double lock core anti-theft label with steel sheet structure). These two kinds of anti-theft labels need to be opened by using special lock openers respectively. The existing lock openers that can open two kinds of anti-theft labels at the same time are fixed on designated workbenches. When customers purchase goods, they must first take the goods with fixed anti-theft labels to the workbench with lock openers to open the lock, which brings inconvenience to customers' shopping: queuing and waiting are needed when it is busy, and it is very inconvenient to open the lock for heavy or large-volume goods. SUMMARY

[0003] The utility model aims at overcoming the shortcomings of the above background technology, and provides a movable combination lock opener, which can open two kinds of anti-theft labels and is convenient to carry and use.

[0004] The technical scheme provided by the utility model is as follows:

[0005] A movable combination lock opener includes a base with a groove, a shell provided with a magnetic block bin and capable of being inserted into the groove for plug-in cooperation, a lock magnetic block group installed in the magnetic block bin, and a spring cable connected to the base and the shell at both ends to connect the base and the shell into one body. The outer surface of the base is provided with a clasp for a belt to pass through. The lock magnetic block group includes a large magnetic block for opening a single lock core anti-theft label and a plurality of small magnetic blocks for opening a double lock core anti-theft label.

[0006] The large magnetic block and the plurality of small magnetic blocks are arranged in the magnetic block bin through a fixing sleeve.

[0007] The large magnetic block and the plurality of small magnetic blocks are kept apart by the fixing sleeve.

[0008] The groove bottom part is fixed with an iron sheet capable of being magnetically attracted to the lock magnetic block group, so that the shell body and the base are connected under the action of magnetic force.

[0009] A recess corresponding to the position of the large magnetic block is formed on the end face of the end of the shell inserted into the groove, and the recess is closed by a stainless steel sheet to serve as the opening position of the anti-theft label when opening the lock.

[0010] The shell and the base are both made of plastic material.

[0011] The utility model has the following beneficial effects:

[0012] This invention can unlock both single-cylinder and double-cylinder anti-theft tags, significantly expanding its application range. Furthermore, shopping mall managers can carry the unlocker on their belts for convenient on-site unlocking for customers, improving service quality. The base and housing are connected by a spring steel cable, preventing the housing from being lost due to detachment from the base, ensuring safety and reliability. When the base and housing are engaged, there is an attractive force between the magnet inside the housing and the iron plate inside the base, facilitating the removal and placement of the base during operation. In addition, this invention has a simple structure, is easy to manufacture, and is suitable for widespread application. Attached Figure Description

[0019] The following description, in conjunction with the embodiments shown in the accompanying drawings, provides further details.

[0020] The movable combination unlocking device shown in the figure includes a base 2 with a groove, a housing 4 with a magnetic block compartment and one end of which can be inserted into the groove for interlocking, an unlocking magnetic block assembly installed in the magnetic block compartment, and an elastic steel cable 9 whose two ends are respectively connected to the bottom of the base and the bottom of the housing to connect the base and the housing into one unit.

[0021] This is similar to a conventional lock pick;

[0022] The improvement of this utility model is that a buckle 1 is provided on the bottom surface of the base. The buckle can be inserted into the belt of the mall manager, so that he can carry it with him to serve the mall consumers.

[0023] Second, the unlocking magnetic block group includes a large magnetic block 6 and a plurality of small magnetic blocks 5 (four small magnetic blocks are shown in the figure); the large magnetic block is specially used for unlocking the single lock core anti-theft label of the three-ball structure; and the plurality of small magnetic blocks are specially used for unlocking the double lock core anti-theft label of the steel sheet structure. In this way, the anti-theft label of the two structures can be unlocked respectively.

[0024] As shown in the figure: the shell 4 is provided with a cavity (the cavity serves as a magnetic block bin) and an open top end face, the large magnetic block and the plurality of small magnetic blocks are arranged in the magnetic block bin through a fixing sleeve 7, and then a magnetic block bin cover 8 is screwed and fixed (the magnetic block bin cover serves as the bottom end face of the shell). The fixing sleeve is formed by injection molding; the fixing sleeve is provided with mounting positions of the large magnetic block and the plurality of small magnetic blocks, so that the large magnetic block and the plurality of small magnetic blocks can maintain a proper spacing.

[0025] The groove is fixed with an iron sheet 10 capable of being magnetically attracted to the unlocking magnetic block group at a groove bottom position; the groove bottom position is provided with a cavity, the iron sheet is mounted in the cavity and is screwed and fixed by the base cover 3; one end of the bolt of the fixing buckle also protrudes in the cavity and is screwed and matched by a nut. The iron sheet can be magnetically matched with the unlocking magnetic block group, so that the shell and the base can be magnetically attracted; the separation and connection of the shell and the base are particularly convenient.

[0026] The end face of the shell inserted into the groove is provided with a recess 12 corresponding to the position of the large magnetic block and a mark frame line 13 corresponding to the positions of the plurality of small magnetic blocks. The recess and the large magnetic block are closed by a stainless steel sheet 11; the recess can serve as the unlocking position of the single lock core anti-theft label when unlocking; the stainless steel sheet can isolate the magnetic block bin from the outside, so as to keep the magnetic block bin from being polluted and keep the magnetic force unaffected. When the double lock core anti-theft label is unlocked, the unlocking area (corresponding to the two steel sheets in the anti-theft label) of the anti-theft label is only needed to be aligned with the mark frame line 13, so that the unlocking can be realized.

[0027] The working principle of the utility model is:

[0028] When the unlocking device is not needed, the base and the shell can be attracted to be integrated, and the unlocking device can be carried by the buckle. When the unlocking device is needed, only a certain external force (greater than the magnetic force) is needed to pull out the shell from the base, the anti-theft label to be unlocked is placed in the specified position of the unlocking device, and the anti-theft label can be opened under the action of the magnetic force; obviously, the unlocking of the single lock core anti-theft label and the double lock core anti-theft label needs to be placed in the respective unlocking positions.
