Abstract

The utility model relates to a lock, wherein, a blocking sheet is arranged in a guiding rail formed by a guiding sheet arranged in the front part of a main body, and a rotating sheet is inserted into a guiding groove arranged on the blocking sheet through a rotating shaft which is arranged at the front part of the rotating sheet. A driving shaft of the front part of a motor passes through a containing hole of a face plate ahead a positioning sheet, and the driving shaft is placed into a fixing hole above the motor. An upper closing cover is covered above the back end of the main body, and a circuit board is arranged at the lower position of a hollow part of the main body. A lower closing cover is covered on the circuit board, a lock head of the front end of the lock is sheathed into a through hole of the lock head arranged in the lower closing cover and the circuit board, and therefore, a double theft-proof function is performed and a keyhole can be prevented from being cram with foreign matters.

Description

Anti-theft lock device

The utility model relates to a kind of lockset.

At present, the tapered end part of lockset directly is installed on the door-plate mostly, its lockhole directly exposes in the door-plate outside, do not set up and there are any safeguard procedures of obstruct of appointing, in addition, some tapered end front end is equiped with the keyhole barrier sheet of turn arbitrarily, but, because of its barrier sheet there is no any holding structure,, and cause lockset to open so keyhole easily suffers the people to fill in foreign matter within it easily, so anti-theft feature is limited, and can't effectively completely cut off the situation generation that lockhole exposes, if can design a kind of Stability Analysis of Structures, simple certain barrier sheet structure must increase the anti-theft effect of lockset, and improve its whole surcharge.

In view of this, the purpose of this utility model provides a kind of anti-theft lock device, and it is to borrow motor driven rotary sheet to rotate, and drives that barrier sheet is upper and lower to be moved, and reaches to open lockhole and close obturator hernia, realizes double anti-theft and prevents that keyhole from being filled in foreign matter.

The purpose of this utility model is achieved in that a kind of anti-theft lock device, comprise main body, barrier sheet, revolving fragment, spacer, motor, upper cover, circuit board, following capping and lockset are formed, it is characterized in that: barrier sheet is inserted in the formed guide rails of guide piece in main body the place ahead, revolving fragment is inserted in the guide groove on the barrier sheet with the turning cylinder in its place ahead, the place ahead power transmission shaft of motor passes the containing hole on the panel of spacer the place ahead, and insert in the motor fixing hole of revolving fragment top, upper cover covers above body rear, circuit board places place, below, main body vacancy again, following capping covers on circuit board, and the tapered end of lockset front end partly penetrates in down capping is bored a hole with the tapered end in the circuit board; Described barrier sheet is provided with the alloy sheet over against lockhole.

Owing to adopt such scheme: the tapered end front end is to the alloy sheet the place ahead on barrier sheet, reaches double anti-theft and prevents that keyhole from being filled in foreign matter.

Below in conjunction with drawings and Examples the utility model is further specified.

Fig. 5 user mode figure of the present utility model.

Among the figure: 1 main body, 11 stators, 12 projections, 121 connecting holes, 13 guide piece, 14 lockholes, 2 barrier sheets, 21 guide grooves, 22 alloy sheets, 3 revolving fragments, 31 fixing holes, 32 turning cylinders, 4 spacers, 41 containing holes, 42 perforation, 5 motors, 51 power transmission shafts, 6 upper covers, 7 circuit boards, the perforation of 71 tapered ends, 72 perforation, 8 times cappings, the perforation of 81 tapered ends, 82 projections, 9 locksets, 91 tapered ends.

As shown in Figure 1, 2, the utility model comprises main body 1, and barrier sheet 2, revolving fragment 3, spacer 4, motor 5, upper cover 6, circuit board 7, capping 8 down, lockset 9 are formed, wherein:

Main body 1 is hollow framework design, centre, right side edge and lower edge place respectively convex with a stator 11 above main body, inboard both sides respectively are provided with two projections 12 in main body 1 the place ahead in addition, and 12 of two side projections are provided with two guide piece 13, and the below is provided with a lockhole 14 thereon in the middle of two guide piece 13;

Barrier sheet 2 is a square lamellar body, and the top is provided with horizontal strip guide groove 21, and guide groove 21 belows are provided with a circular alloy sheet 22 greater than lockhole 14 diameters;

Revolving fragment 3 is a square lamellar body, and the top is provided with a fixing hole 31, and is convexly equipped with a turning cylinder 32 thereon below revolving fragment 3;

Spacer 4 offers a containing hole 41 in the middle of the plate face in the wings, and a perforation 42 is respectively established thereon in containing hole 41 both sides;

Motor 5 the place aheads are a power transmission shaft 51, are to commonly use product therefore, and are of a great variety, so not narration one by one;

Upper cover 6 is a L shaped sealing framework;

Circuit board 7 is provided with tapered end perforation 71 and is provided with several perforation 72 thereon in each corner of underside circuits plate 7 in the centre;

Be provided with tapered end perforation 81 in the middle of the following capping 8 and be provided with several projections 82 in each corner of following capping 8 inboards;

Lockset 9 the place aheads are convexly equipped with a tapered end 91, and this lockset 9 is to commonly use product.

As Fig. 3, shown in 4, during assembling barrier sheet 2 placed in the main body in two guide piece, the 13 formed guide rails, continuous turning cylinder 32 with revolving fragment 3 rears penetrates in the guide groove 21 of barrier sheet 2 tops, after passing the containing hole 41 in spacer 4 the place aheads with the power transmission shaft 51 of motor 5 again, borrow two-screw to pass perforation 42, and be connected motor 5 front end faces, continue spacer 4 is inserted main body 1 back side top, and power transmission shaft 51 front ends are penetrated, and be fastened in the motor fixing hole 31 of revolving fragment 3 tops, again upper cover 6 is covered above main body 1, and main body 1 below is inserted with a circuit board 7 in addition, one continuous will descend capping 8 to place on the circuit board 7, the tapered end that passes down the tapered end perforation 81 of capping 8 and circuit board 7 with the tapered end 91 of a lockset 9 71 places of boring a hole again, and rest on lockhole 14 medial surfaces, penetrate down in regular turn the perforation 72 of the projection 82 and the circuit board 7 of capping 8 again with screw, main body 1 in, locate in the screw hole on institute's projection of setting up 12, promptly finish overall package at this moment and move and screw in.
