Description

Electronic product shelf

The present invention relates to a shelf structure, and more particularly to an electronic article shelf that is easy to operate and effectively locks theft.

According to the advancement of technology, 3C electronic products such as tablets and mobile phones are almost one-handed, and the electronic products are light and easy to carry, and the electronic products are high-priced products, so they are often the target of thieves. Especially in places with large crowds or in unmanned offices, the loss of electronic products is often caused by accidental or negligent circumstances. Therefore, in order to prevent electronic products from being stolen, the store will generally display electronic products in the window. When consumers are interested, they will ask the sales staff to take it out of the window, which will inevitably reduce the consumer's inquiry about the product, and will also block the consumer's product because the salesperson can't respond to the consumer's request in time. The willingness to experience is not conducive to the sale of the product. Another display stand is for the user to pick up the electronic product of the display, and the display stand is equipped with an inductive device, and the electronic product immediately alerts when it leaves the sensing device. Such a display stand can only be activated passively when theft, if the consumer just does not intend to take the electronic product away from the sensing device This alert behavior will scare the consumer, resulting in misunderstanding and consumer dissatisfaction. The passive anti-theft effect is not as effective as locking the electronic product on the shelf to directly eliminate the electronic product being stolen. Occurs, in addition, the lack of a clamping mechanism for the electronic product itself is usually based on a plurality of symmetrical support arms sandwiched on the display, the support arm needs to independently adjust the clamping position, and the support arm is usually spring tension The clamping force is formed, and the clamping mode is not only difficult to operate, and the shortage of the clamping force is easily damaged by the external shock due to external shock, and the anti-theft effect cannot be prevented due to insufficient structural strength. Destructive stolen, combined with the above-mentioned lacks are the technical problems that the creative needs to improve.
