Description

An electronic anti-theft drawer

【Technical field】

The utility model relates to an electronic anti-theft drawer.

【Background technique】

Existing drawer locks are generally divided into common locks and electronic locks. When the ordinary drawer lock is closed, most drawer locks require additional actions to lock the drawer, so it is easy to forget to close the lock and cause unnecessary losses. Moreover, the bolts of most drawer locks are installed in front of the drawer box, which is easier to be pried open; while electronic drawer locks are electrically controlled, and generally can only be used when there is electricity, and the unlocking method is relatively simple. Electricity just can't open drawer, and the structure of existing electronic drawer is complicated, and cost is higher.

【Content of invention】

The purpose of the utility model is to provide an electronic anti-theft drawer with simple structure, high degree of automation, various ways of unlocking and good anti-theft performance.

The purpose of this utility model is achieved in that:

An electronic anti-theft drawer, including a drawer box, with guide rails on both sides of the bottom of the drawer box. The middle part is fixed by a fulcrum on the base, an electromagnet is installed on the base, one end of the lever is connected with the mandrel of the electromagnet, and the other end of the lever is provided with a block that can be stuck in the clamping hole.

An electronic anti-theft drawer as described above is characterized in that a manual lock mechanism is installed next to each drawer box. The manual lock mechanism includes a lock core connected to a connecting rod, and one end of the connecting rod is provided with a dial block, and a lever is provided on the lever, and the lever can be moved by the lever to make the block withdraw from the hole.

An electronic anti-theft drawer as described above is characterized in that a multi-head lock control mechanism is installed beside the drawer box, the control mechanism includes a button, the button is connected to one end of the connecting shaft, the other end of the connecting shaft is connected to the push rod, and the push rod Then be arranged on the front ends of the driving levers of a plurality of drawer boxes, and return springs are arranged on the connecting shafts.

An electronic anti-theft drawer as described above is characterized in that a spring device is installed behind the drawer box.

The utility model has the advantage that the drawer box can be automatically closed by pushing the drawer box without any additional action; since the lock tongue block of this product is installed at the rear of the drawer, it cannot be pried open. Moreover, the electromagnet control is adopted, which increases the safety of the drawer and reduces the manufacturing cost of the electronic anti-theft lock. At the same time, a mechanical lock structure is set up, and two unlocking methods, electric control and mechanical, can be used, which solves the problem that the lock cannot be unlocked during a power failure. The utility model is easy to use and simple in structure, can be used alone, and can be used in multi-layer structures, such as safes, parts cabinets, medicine cabinets and the like.

【Detailed ways】

An electronic anti-theft drawer, comprising a drawer box 1, guide rails 2 are provided on both sides of the bottom of the drawer box 1, guide grooves 4 are provided on the base 3 of the drawer box 1 corresponding to the guide rails 2, and a tail of the drawer box 1 is welded The stop block 5 has a locking hole 6 on the stop block 5 . Electromagnet 7 is installed on each drawer box base 3, and lever 8 is installed on base 3, and the middle part of lever 8 is fixed by supporting shaft 9 that is located on base 3, and lever 8 can rotate around supporting shaft 9, and lever One end of 8 is connected with the mandrel 10 of the electromagnet 7, and the other end of the lever 8 is provided with a block 11, when the drawer box 1 is pushed inward to close, under the spring force on the mandrel 9 of the electromagnet 7, the card will Block 11 is stuck in the hole 6 of block 5 to form a lock. When electromagnet 7 was energized, mandrel 9 pulled back lever 8 to rotate clockwise, so that block 11 was withdrawn from hole 6 . form a lock.

Next to each drawer box 1, a manual lock mechanism 12 is installed. The manual lock mechanism 12 includes a lock core 13, which is connected with a connecting rod 14, and the other end of the connecting rod 14 is provided with a toggle block 15. A lever 16 is provided on the lever 8 . When the drawer box 1 is in the locked state, insert the key, turn the lock core 13 clockwise, the lock core 13 drives the connecting rod 14 to rotate, the shifting block 15 moves the driving rod 16, and the lever 9 is rotated clockwise, and the locking block 12 moves from the locking Exit in the hole 5 to form an unlock.

In order to enable a plurality of drawers to be opened and closed uniformly, a multi-head control lock mechanism 17 is installed beside the drawer box 1. The multi-head control lock mechanism 17 includes a button 18 and a control lock 22 arranged on the button. The connection between the button 18 and the connecting shaft 19 One end is connected, and the other end of connecting shaft 19 is connected with push rod 20, and push rod 20 is then arranged on the front end of driving rod 16 of a plurality of drawer boxes. A return spring 21 is provided on the connecting shaft 19 . The multi-head control lock mechanism 17 can be applied to all opening and closing of multi-layer structure (such as safe, parts cabinet, medicine cabinet) cabinets. When all the drawer boxes 1 are in the locked state, open the safety lock, press the button 18, the button 18 pushes the connecting shaft 19, and the connecting shaft 19 pushes the push rod 20. Push rod 20 promotes driving lever 16, makes the block 11 on the driving lever 9 turn out from locking hole 6, and all drawer boxes are all opened.

A spring device 23 is installed on the base of the drawer box 1 , and when the block 11 turns out from the hole 6 , the drawer box 1 is pushed out under the elastic force of the spring device 23 .

There are three ways to use the utility model:

Method 1: Use electronically controlled switch lock

As shown in Figure 1, take the right side as an example. When the drawer box is opened, it is necessary to close the lock and push the drawer box 1 to move inward. At this time, the stop block 5 moves inwardly with the drawer box 1, and the block 11 on the lever 8 snaps into the hole 6 of the stop block 5, and the locking action is completed. When unblanking is needed, as long as the computer control system sends an instruction to energize the electromagnet 7, the mandrel 10 moves to the right, the lever 8 and the driving lever 16 rotate with the shaft 10 as the center point, and the block 11 is rotated out from the hole 6. This moment, drawer ejects under the effect of spring device 23. The unlocking process is complete.

Method 2: Use manual switch lock

In the case of no power, you can use the key to unlock directly. Insert the key into the lock core 13, turn the lock core 13, the lock core 13 drives the connecting rod 14 to rotate, the connecting rod 14 also drives the shifting block 15 to rotate, the shifting block 15 moves the driving rod 16, and the block 11 on the driving rod 16 moves from The card hole 6 is rotated out to realize unlocking.

Method 3: Use the button to open and close the lock uniformly.

When all the drawer boxes 1 are in the closed state, open the safety lock 22, press the button 18, the button 18 pushes the connecting shaft 19 to move inwardly, and the connecting shaft 19 pushes the push rod 20 to act. Push rod 20 promotes the driving lever 16 behind all drawer boxes 1 to rotate, and block 11 is turned out from card hole 6, and all drawer boxes are all opened.
