Specific embodiment

Below by way of specific embodiment, the utility model will be further described.

Referring to figs. 1 to Fig. 8, a kind of safety lock, including lock body 100 and lock bridge 10, the lock body 100 are equipped with main body 20, rear cover 30, driving mechanism 40, locked component 50, front cover 60 etc..The rear cover 30 and front cover 60 are respectively arranged on 20 two sides of main body, should It is detachably to cooperate between rear cover 30 and main body 20, the common detachable assembly method such as can be threaded connection, snaps connection. Mountable solar panel 70 between the rear cover 30 and main body 20 is fixed with battery 71 on the solar panel 70, which passes through solid Determining frame 72 cooperates screw 73 to be fixed in main body 20.Axially extending slot 21 is offered in the middle part of the main body 20, main body 20 is close 30 side of rear cover is additionally provided with the mounting groove 22 vertical with slot 21.The mounting groove 22 is open at one end, and the other end is slotting equipped with being connected to The through-hole of slot 21.10 one end of lock bridge is inserted into and is limited in the slot 21 of main body 20, can be steered and move along slot 21.

Lock bridge 10 is located at 21 one end of slot and is respectively equipped with the second inclined-plane 11, aperture 12, lock pair slot 13 and positioning from the bottom to top Slot 14.Positioning bead 23, spring catch 24 are correspondingly provided in main body 20.The locating slot 14 and positioning bead 23 cooperate, at the end of lock bridge 10 When extraction, work as a buffer.Spring catch 24 is used in the extraction of lock bridge 10 to specific position, and alignment apertures 12 are simultaneously inserted into, with resistance Only lock bridge 10 is extracted completely.

The locked component 50 of the utility model is set in mounting groove 22, for when lock bridge 10 is locked, locking or solving Lock rear cover 30.Specifically, the locked component 50 is equipped with locking piece 51, elastic component 52 and stud 53 etc..The rear cover 30 is equipped with locked groove 31, when rear cover 30 is fixed in the main body 20 of lock body 100, the mounting groove 22 of locked groove 31 and main body 20 is opposite.The stud 53 It is fixed on 22 open end of mounting groove, and is equipped with through-hole.Locking piece 51 is movably arranged in mounting groove 22, and both ends are worn respectively The through-hole of mounting groove 22 and stud 53 is crossed, locking piece 51 is equipped with tapered end 54 towards one end of lock bridge 10, and the other end is plane. Elastic component 52, which is opened, to be peaked between 21 side of close slot of locking piece 51 and stud 53.Locked groove 31 is equipped with the conical surface 32 of indent, should 32 internal diameter of the conical surface is to gradually reduce along indent direction.

Driving mechanism 40 is fixed in main body 20 and is equipped with sheave 41, and the sheave 41 is controlled after being triggered and screws in lock pair The realization of lock bridge 10 is locked in slot 13 to shut, or is screwed out lock and paid slot 13 to unlock the realization of lock bridge 10 and unlock.The sheave 41 is located at lock When paying in slot 13,41 top surface of sheave distance lock pays 13 top surface a distance of slot.

Further, the utility model is additionally provided with detection device 80 and lock rod spring 81, which sets There is spring leaf 82, the other end is fixed on the bottom end of slot 21, which is located at 82 lower section of spring leaf and and driving mechanism 40 are directly or indirectly connected to send trigger signal.

The utility model can be used in common electronic lock (including padlock), be equipped with main control board 90, governor circuit Plate 90 is equipped with master chip, several indicator lights 92 and other electronic components.Master chip receives input password and is judged, then controls The movement of driving mechanism 40 is completed to unlock, be shut.Indicator light 92 is connected with master chip, is used to indicate unlocking or shuts.Driving machine Structure 40 includes motor 42 and driving member 43, which is connected with driving member 43, and driving member 43 contacts biography with sheave 41 Dynamic, which is connected to receive the trigger signal shut with detection device 80.

Main control board 90 is fixed in main body 20 by fixed plate 91, and the governor circuit on main control board 90 can be adopted With Bluetooth circuit or fingerprint circuit or sound circuit or key circuit or its combination of two etc., when the password of input is correct, then control Motor 42 processed rotates, and driving member 43 is driven so that 41 whiz of sheave lock pair slot 13 transfers to lock at this point, indicator light 92 lights manually Beam 10 makes it move up a distance to unlock, and locking piece 51 unlocks rear cover 30 simultaneously.

When the active force that no lock bridge 10 squeezes, locking piece 51 is close to the right main body under the effect of elastic component 52 20, it is just moved to the left until under the effect of the mutual extrusion power of lock bridge 10.When padlock is in unlocking condition (as shown in Figure 5), It realizes and shuts that detailed process is as follows:

Press lock bridge 10, end along slot 21 move down a distance after push spring leaf 82, and then push locking bar After 81 a distance of spring, until when aperture 12 be aligned locking piece 51 when, under the action of elastic component 52,51 one end of locking piece into Enter aperture 12, the other end leaves rear cover 30；Continue to push lock bridge 10, the tapered end 54 of locking piece 51 is squeezed by 12 edge of aperture It under pressure effect, is gradually backed out aperture 12 and is moved to the left, continue to push lock bridge 10 until the bullet that is connected with lock rod spring 81 Reed 82 touches detection device 80, at this point, 80 trigger signal of detection device, to master chip, master chip controls driving mechanism 40 Motor 42 rotates, and then drives sheave 41 to screw in the lock pair realization of slot 13 and shut, and indicator light 92 extinguishes.At this point, just unclamping hand, locking bar The gradually rebound upwards under own resilient effect of spring 81, while lock bridge 10 being pushed to move up, locking piece 51 is in elastic component 52 Under active force, it is moved right into aperture 12 again, because the elastic force of lock rod spring 81 is much larger than 52 elastic force of elastic component, then, lock Bar spring 81 continues to press on lock bridge 10 and moves up, under the action of extruding force of the tapered end 54 by 12 edge of aperture, so that Locking piece 51 is moved to the left to the contact of the conical surface 32 on rear cover 30 again, thus rear cover 30 can be prevented to be unscrewed, after realizing locking Lid 30 is now in the state of shutting, as shown in Figure 7.Above-mentioned entire change procedure referring to figure 5., Fig. 6, Fig. 7, Fig. 8.

It under the state that shuts, when rear cover 30 to be opened replaces battery 71, needs to press lock bridge 10, is locked when aperture 12 is aligned When determining part 51, under the action of elastic component 52,51 one end of locking piece enters aperture 12, and the other end leaves rear cover 30, at this point, passing through Force can unscrew rear cover 30, referring to Fig. 7, Fig. 8.

The above is only the specific embodiments of the present invention, but the design concept of the present invention is not limited thereto, All non-essential modifications to the present invention made by this concept should belong to the row for invading scope of protection of the utility model For.
