Description

Technical Field

[0001] The utility model relates to the field of cabinet locks, in particular to a cabinet lock with multi-function conversion. Background Art

[0002] In the existing field of electronic cabinet locks, electronic cabinet locks with hooks and electronic cabinet locks with card swipe are generally developed separately. Most of the accessories of the two products are not interchangeable. If two locks need to be produced, separate materials need to be prepared. In addition, the hook and lock body of existing electronic locks with hooks are integrated. If a circuit board needs to be installed, a hole needs to be opened on the circuit board to avoid the hook, which reduces the area of ​​the circuit board and there is a gap after the circuit board is installed, resulting in weak waterproof and dustproof capabilities of the lock body. Summary of the invention

[0003] Based on the above content, in order to solve the shortcomings of existing products, a cabinet lock with multi-function conversion is proposed, which can effectively solve the commonality of spare parts for different products to reduce production and storage pressure, and has good waterproof and dustproof electronic cabinet lock.

[0004] The technical solution of the utility model is achieved as follows: a cabinet lock with multifunctional conversion comprises a lock body, a handle, a back cover, a padlock seat, a radio frequency antenna box, a circuit board, an electromagnet, a lock core mechanism and a cabinet door locking mechanism.

[0005] Preferably, a handle groove is provided on the front side of the lock body, the handle is arranged in the handle groove, and the lock body and the handle are connected by a rotating shaft mechanism. There are four through holes in the handle groove of the lock body, two of which are screw through holes for fixing a padlock seat or a radio frequency antenna box, and the padlock seat has an internal threaded hole for fixing it to the surface of the handle groove with screws, and the padlock seat has a padlock hole for adding an external padlock; the threading through hole is a through hole for connecting the radio frequency antenna cable in the middle of the two screw through holes, and the radio frequency antenna box is made of nylon, and a fixed inner hole is provided in the radio frequency antenna box for fixing it to the surface of the handle groove with a self-tapping screw, and the connecting cable passes through The threading through hole can be connected to the PCB circuit board on the back of the lock body; the light guide column through hole is used to place the light guide column, which is used to guide the LED light on the PCB circuit board for flashing prompts; the PCB circuit board is placed on the back of the lock body, and a circuit board groove is provided on the back of the lock body. There are circuit board positioning studs in the circuit board groove, and the circuit board positioning studs are used to install the PCB circuit board. The electromagnet positioning hole is used to place the electromagnet bracket, and the electromagnet is sleeved in the electromagnet bracket. The PCB circuit board and the electromagnet are both installed on the back of the lock body. When the lock is installed, it effectively blocks rainwater from spraying from the front to achieve the purpose of waterproofing.

[0006] Preferably, there is a corresponding back cover on the back of the lock body. When the circuit board and the electromagnet are installed, the back cover is fixed with screws to achieve the purpose of dust prevention; the back cover is provided with an opening, and the opening is used to pass an external cable to the PCB circuit board. The opening has a corresponding baffle, and the baffle is used to clamp the cable at the opening after passing through the opening, which can effectively achieve the purpose of dust and water prevention.

[0007] Preferably, the upper end of the handle is connected to the rotating shaft mechanism, and when the handle rotates, it drives the rotating shaft and the cabinet door locking mechanism connected to the rotating shaft to achieve the purpose of locking or opening the cabinet door. The lock core mechanism is used to lock the handle at the lower end of the handle. A protective cover is provided at the handle lock core to prevent the lock core from dust and water. An opening is provided in the middle position of the handle for passing a padlock seat or a radio frequency antenna box. A handle light guide column through hole is provided on the front side of the handle corresponding to the position of the lock body light guide column for installing the handle light guide column. A permanent magnet placement hole is provided on the back side of the handle near the lock core mechanism for placing a permanent magnet. The permanent magnet cooperates with the magnetic induction element on the PCB circuit board to detect the switch state of the handle.

[0008] Preferably, after the lock body, light guide column, handle, lock core mechanism, handle light guide column, permanent magnet, protective cover, back cover, baffle, PCB circuit board, LED lamp, external cable, magnetic induction element, electromagnet, electromagnet bracket, shaft mechanism, cabinet door locking mechanism, and device plate are assembled, a padlock seat is optionally installed in the two screw through holes, and the multi-functional convertible cabinet lock is converted into an electronic cabinet lock with a padlock; or a radio frequency antenna box is optionally installed in the two screw through holes, and the connecting cable is connected to the PCB circuit board, and the multi-functional convertible cabinet lock is converted into an electronic cabinet lock that can be swiped by a card; switching between two cabinet locks with different functions can be completed by only replacing the padlock seat or the radio frequency antenna box, which can effectively reduce the types of accessories required for the production of cabinet locks with two different functions, avoid the need to prepare two different cabinet locks separately, and reduce storage pressure.

[0009] Preferably, after the padlock seat is installed in the two screw through holes, the PCB circuit board can be installed in the circuit board groove on the back of the lock body, so that the PCB circuit board can effectively avoid water vapor erosion from the front of the lock body, achieving a waterproof and dustproof effect. The padlock seat of a traditional cabinet lock with a hanging design is integrated with the lock body. When installing the circuit board, it needs to be installed from the front of the lock body. At the same time, a hole corresponding to the air-proof padlock seat needs to be dug out on the PCB circuit board, thereby greatly reducing the effective area of ​​the PCB circuit. The PCB circuit board is installed in the circuit board groove on the back of the lock body, and the problem of the effective area of ​​the PCB circuit being occupied can be avoided.

[0010] In summary, the beneficial effects of the present invention are:

[0011] 1. When the padlock seat is installed on the lock body, the multifunctional cabinet lock of the utility model can be used as an electronic cabinet lock with a padlock.

[0012] 2. When the lock body is installed with a radio frequency antenna box, the multifunctional cabinet lock of the utility model can be used as a card-swipe electronic cabinet lock.

[0013] 3. The utility model product can switch between two different types of electronic cabinet locks by optional padlock holder and radio frequency antenna box. Only one accessory needs to be replaced to change into two locks, which can effectively reduce the types of accessories required for the production of cabinet locks with two different functions, avoid the need to prepare two different cabinet locks separately, reduce the pressure of warehouse inventory, and achieve better waterproof and dustproof effects.
