Abstract

The utility model relates to a tamper-resistant structure of an electronic intelligent lock consisting of an elector motor, a bolt, a double gear, a driving wheel, a middle wheel, a cam, a retaining piece and a spring. The bolt is fixed and connected with a lock gear and provided with a gap. The driving wheel, the middle wheel and the cam that pokes the retaining piece to swing are arranged on a same shaft. When in use, the double gear is driven by the electric motor to turn and drives the driving wheel by mesh transmission; and the bolt is rotated by the mesh transmission of a toothed gear fixed on the bolt driven by the middle gear. Meanwhile, the retaining piece leaves away the gap under the effect of the cam and resets and contacts the gap under the effect of the force of the spring. The tamper-resistant structure of the electronic intelligent lock has the characteristics of simple structure and high safety and can be widely applicable to recreation spots such as a Sauna room.

Description

The pick-proof structure of electronic intelligent lock

Technical field

The utility model relates to a kind of structure of lock, more particularly, relates to a kind of pick-proof structure of electronic intelligent lock.

Background technology

Along with the raising of science and technology development and administrative skill, people's live and work environment gets up electronic more, intelligent.Electronic intelligence is locked in and has obtained in the public place of entertainment using widely, and it is stores safety not only, and help staff's management.Yet because personnel's complexity of turnover public place of entertainment, the theftproof performance of locker lock is low, a little less than the dead bolt strength of lock, is easy to dead bolt is dialled back from opening locker door with little steel wire.For the locker that stores valuables, suffer lawless person's destruction unavoidably, cause owner's property to incur loss, influenced the normal order of public place of entertainment.

The utility model content

The purpose of this utility model provides a kind of safe, pick-proof structure of preventing the electronic intelligent lock that dead bolt is prized.

In order to achieve the above object, by the following technical solutions of the present utility model: a kind of pick-proof structure of electronic intelligent lock, comprise motor and dead bolt, also comprise twin-stage gear, drive, breast wheel, cam, brake(-holder) block and spring;

Described dead bolt fixed connection lock gear and offer breach thereon, described twin-stage gear is made up of coaxial gear wheel and pinion, described drive, breast wheel and stir the coaxial installation of cam of brake(-holder) block swing;

Described motor-driven twin-stage gear rotates, twin-stage meshed transmission gear drive, and fixing lock gear rotates dead bolt on the breast wheel engaged transmission dead bolt;

Simultaneously, described brake(-holder) block leaves breach and resets and contact breach at the active force of spring under action of cam power.

Described brake(-holder) block is a Y-shaped, and it is made up of left arm and right arm, and the side of right arm contacts with the external surface of cam is movable, and the head end of left arm contacts with the breach of described dead bolt is movable.

The head end of described left arm is provided with block, and this block contacts with breach is movable.

The output shaft of described motor connects a driving gear, and motor is by driving gear engaged transmission twin-stage gear.

The output shaft of described motor connects a worm screw, and motor is by worm engaging transmission twin-stage gear.

The output shaft of described motor connects a screw rod, and motor is by screw engages transmission twin-stage gear.

Described lock gear is half gear.

Flexibly connect between described drive and the breast wheel.

Compared with prior art, the utility model, makes the head end contact of brake(-holder) block block the breach of dead bolt, thereby limits the rotation of dead bolt under the effect of spring owing to be provided with brake(-holder) block, improves the safety of locking, and reaches the purpose of pick-proof.

Description of drawings

Fig. 1 is a structural representation of the present utility model;

Fig. 2 is the schematic diagram of the utility model unlocking condition;

Fig. 3 shuts the schematic diagram of state for the utility model.

The specific embodiment

Below in conjunction with most preferred embodiment and accompanying drawing, the utility model is described in further detail.

As shown in Figure 1, the utility model by motor 1, worm screw 3, twin-stage gear, drive 6, middle 7 take turns, cam 8, brake(-holder) block 14, spring 15, dead bolt 10, half gear 9 form.The twin-stage gear is made up of gear wheel 5 and pinion 4, and be installed in coaxial on.Worm screw 3 is installed on the output shaft 2 of motor 1.Coaxial the going up of drive 6 installed cam 8, and the below of drive 6 is provided with brake(-holder) block 14, and brake(-holder) block 14 is Y-shaped, brake(-holder) block 14 is made up of left arm 12 and right arm 13, the head end of left arm 12 is provided with block 11, and the inboard of right arm 13 contacts with cam 8, and the bottom of brake(-holder) block 14 connects spring 15.Offer a breach 16 on the dead bolt 10, block 11 contacts with breach 16, and is connected and fixed half gear 9.Worm screw 3 and gear wheel 5 engaged transmission, pinion 5 and drive 6 engaged transmission, breast wheel 7 and half gear, 9 engaged transmission.Be provided with flexible structure between drive 6 and the breast wheel 7, dead bolt 10 is in motion process as break down and can not destroy part in the pick-proof structure.

Operating principle of the present utility model is as follows: as shown in Figure 2, lock is in unlocking condition.When closing to the doorstep, doorframe buckle pointing tongue 16 makes sharp tongue 16 retraction housing internal trigger circuit, motor 1 is just changeing startup, and worm screw 3 engaged transmission gear wheels 5 rotate counterclockwise, and pinion 4 engaged transmission drives 6 clockwise rotate, half gear 9 on the breast wheel 7 engaged transmission dead bolts 10 rotates counterclockwise, simultaneously, cam 8 clockwise rotates, and brake(-holder) block 14 is counter-clockwise swing under the active force of spring 15, make block 11 contact breach, thereby the rotation of restriction dead bolt 10, at this moment, lock is in the state of shutting (Fig. 3).In any case this structure prizes dead bolt, all it can't be prized, strengthened the safety of electronic intelligent lock.

As shown in Figure 3, lock is in the state of shutting.When the electron key circuits for triggering, motor 1 counter-rotating starts, and worm screw 3 engaged transmission gear wheels 5 clockwise rotate, and pinion 4 engaged transmission drives 6 rotate counterclockwise, half gear 9 on the breast wheel 7 engaged transmission dead bolts 10 clockwise rotates, simultaneously, cam 8 rotates counterclockwise, and promotes brake(-holder) block 14 and swings clockwise, make block 11 leave breach, at this moment, sharp tongue 16 stretches out and resets, and lock is in unlocking condition (Fig. 2).

Although in conjunction with the accompanying drawings preference of the present utility model is implemented to be described above; but the utility model is not limited to the above-mentioned specific embodiment; the above-mentioned specific embodiment only is schematic; rather than it is restrictive; those of ordinary skill in the art is under enlightenment of the present utility model; not breaking away under the scope situation that the utility model aim and claim protect, can also make many forms, these do not have substantial change and all belong within the protection of the present utility model.
