A programmable electronic lock with a closing tongue is actuated with an actuating mechanism formed by a mobile knob acting as a button joined to the closing tongue. Actuation of the mobile knob generates a movement of the closing tongue and closure of the lock. Recovery of the mobile knob to its initial position generates an opening of the lock. Furthermore, an electronics board is activated with a transponder key and controls operation of the lock by deactivating and subsequently activating a blocking mechanism formed by a motor that actuates a punch via a gear mechanism. When the punch is in a blocking position it is located against the actuating mechanism. When the punch is in an unblocking position, it is separated from the actuating mechanism and allows the movement of the closing tongue by unblocking the actuating mechanism.

The invention claimed is: 1. A programmable electronic lock arranged in a casing with a cover, comprising: a battery; a tongue with two side shafts, which in an opening position of the lock remains inside the casing, and in a closing position of the lock moves linearly and partially exits the casing, wherein the linear movement of the tongue defines a longitudinal tongue axis; an actuating mechanism configured to actuate the tongue, the actuating mechanism located along a guide axis perpendicular to the longitudinal tongue axis: a mobile knob comprising side grooves in which the two side shafts of the tongue are introduced, and a first spring for the recovery of the mobile knob, wherein pressure of the mobile knob generates partial exit of the tongue from the casing and the closing position of the lock, and recovery movement of the mobile knob generates entry of the tongue into the casing and the opening position of the lock; an antenna; an electronics board configured for receiving data emitted by a transponder key through the antenna, the electronics board controlling the operation of the electronic lock and activating and deactivating; and a blocking mechanism of the actuating mechanism, which unblocks the latter allowing the movement of the tongue and the passage of the lock to its opening position, the blocking mechanism being subsequently actuated by the electronics board after the actuating mechanism moves the tongue again to the closing position, thus blocking the actuating mechanism and preventing the movement of the tongue, wherein the blocking mechanism comprises a motor controlled by the electronics board which actuates a punch by means of a gear system, which in a blocking position is located against the actuating mechanism, blocking the latter and preventing the movement of the tongue, and in an unblocking position is separated from the actuating mechanism, unblocking the latter and allowing the movement of the tongue. 2. The programmable electronic lock according to claim 1, wherein the punch of the blocking mechanism in its blocking position is fixed in a recess made in a surface of the mobile knob, preventing its return movement, thus blocking the actuating mechanism and preventing the movement of the tongue, and in its unblocking position is withdrawn from the recess made in the surface of the mobile knob, driven by the gear system which is actuated by the motor, allowing the return movement of said mobile knob, and thus releasing the actuating mechanism and allowing the movement of the tongue. 3. The programmable electronic lock according to claim 1, wherein the electronics board is reprogrammable according to different operation modes. 4. The programmable electronic lock according to claim 1, further comprising optical detectors arranged in the proximity of the blocking mechanism which detect at any time the exact position of the punch and transmit it to the electronics board for the control of said blocking mechanism. 5. The programmable electronic lock according to claim 1, wherein the electronics board comprises a controller of the battery charge level and prevents the movement of the tongue to the closing position of the lock when it detects that the battery charge level is under a predetermined value. 6. The programmable electronic lock according to claim 1, wherein the antenna consists of a conventional coil. 7. The programmable electronic lock according to claim 1, wherein the antenna is integrated in a printed circuit board. 8. The programmable electronic lock according to claim 1, wherein the blocking mechanism comprises a second spring arranged in a shaft of the punch, in contact with the latter.
