Abstract

The utility model discloses an anti-theft warehouse lock without a key, which is suitable for warehouse gates, unit gates, etc. The utility model has the main structure that a lock case (1) has a rail (14) and a sliding lock bolt (10) with a rack (4); a reversible motor (2), the power of which is supplied by a driving power (2) drives gears to rotate to make the rack do reciprocating movement and to make one end of the lock bolt (10) inserted into or gone out of a lock bolt box (3). Limit switches (9), (13) are limited in the lock bolt (10) and are touched to stop the running of the lick bolt (10). A gravitational safety hook (8) falls into a safety groove (11) at the tail end of the gravitational safety hook after the lock bolt (10) is inserted into the lock bolt box (3), and the gravitational safety hook (8) can be sucked up by a movable iron core of an electromagnet (7) during unlocking time. An FM transmitter (18) sends instruction to the receiver (5) on the lock case (1) to control the driving power (2).

Description

Anti-theft warehouse lock without key

The utility model relates to a kind of gate such as warehouse that is suitable for lock, especially its frame for movement.

The existing lockset that is used for warehouse gate, unit gate is all opened with metal key, not only use trouble, and theftproof performance is poor.Existing electronic or shake control door or door locking device, though can play the effect of lock, complex structure, operation inconvenience, manufacturing and maintenance cost height.

The purpose of this utility model is, designs a kind of antitheft no key storage lock, adopts the motor drive gear tooth bar to realize moving of locking bolt, and shakes the rotation of the described motor of control, have simple in structure, theftproof performance good, characteristics easy to use.

The technical solution of the utility model is, it comprises lock box, bolt box, driving power, reversible motor, limit switch, radio frequency modulatng transmitter and being contained on the lock box and the wireless frequency modulation receiver of its output signal control driving power, its design feature is, the band tooth bar locking bolt that lock box is equipped with guide rail and can reciprocatingly slides on this guide rail, the line shaft of the reversible motor that is contained on the sealed box and connects with driving power has the tooth bar engagement of gear with described locking bolt, one end of locking bolt can extend also can be by wherein withdrawing from the lock box, locking bolt has the limit switch contact of other end shake-up guide rail tail end when this locking bolt slides into the disengaging bolt box of safety groove, the spacing collision block that is contained on the locking bolt touches another limit switch contact after this locking bolt slides into the insertion bolt box, the electromagnet stent that is fixed on the lock box is equipped with the electromagnet that drives iron core, its moving iron core and gravity auxiliary catch middle part is connected, and an end of described gravity auxiliary catch is hinged on the electromagnet stent and the other end has the auxiliary catch that can fall into the locking bolt safety groove.

Make below in conjunction with accompanying drawing and to further specify.

Description of drawings: Fig. 1 is a practical structures, and Fig. 2 is the frequency modulation transmitter profile, in the drawings: the 1-lock box, the 2-reversible motor, 3-bolt box, 4-tooth bar, the 5-FM receiver, 6-electromagnet stent, 7-electromagnet, 8-gravity auxiliary catch, 9, the 13-limit switch, the 11-safety groove, 12-guide rail tail end, 14-guide rail, 15-driving power, the 16-contact alarm, 18-frequency modulation transmitter, the spacing collision block of 19-.

By accompanying drawing as can be known, the utility model has lock box (1), bolt box (3), driving power (15), reversible motor (2), limit switch (9) (13), radio frequency modulatng transmitter (18) and be contained in the wireless frequency modulation receiver (5) of upper and its output signal control driving power (15) of lock box (1), its architectural feature is, the locking bolt with tooth bar (4) (10) that lock box (1) is equipped with guide rail (14) and can reciprocatingly slides in this guide rail (14), it is upper and gear is arranged with tooth bar (4) engagement of described locking bolt (10) with the line shaft that described driving power (15) connects the reversible motor (2) of (being that power supply (15) is to described motor (2) power supply) to be contained in lock box (1), one end of locking bolt (10) can extend also can be by wherein withdrawing from the bolt box (3), this locking bolt (10) touches the contact of the limit switch (13) of guide rail (14) tail end (12) when this locking bolt (10) slides into disengaging bolt box (3) with the other end of safety groove (11), the spacing collision block (19) that is contained on the locking bolt (10) slides into the contact that inserts bolt box (3) rear shake-up limit switch (9) at this locking bolt (10), the electromagnet stent (6) that is fixed on the lock box (1) is equipped with the electromagnet (7) that drives iron core, its moving iron core and gravity auxiliary catch (8) middle part is connected, and it is upper and the other end has the auxiliary catch of the safety groove (11) that can fall into locking bolt (10) that an end of described gravity auxiliary catch (8) is hinged on electromagnet stent (6). Described limit switch (9) can be contained in the suitable position of lock box (1) or guide rail (14). Described driving power (15) can connect civil power or accumulator jar, considers power failure Factor, but when connecing civil power the adjunction emergency power supply. Described FM reception and emitter (5) (18) are the prior art structure, can adopt the common ratio emitter of two channels, or adopt automobile-use four-way frequency modulation ratio emitter, and emission, reception ultimate range are selected in 10 to 100 meters scopes and are advisable. It is good that described motor (2) adopts the low speed reversible electric machine. Also the touch mode alarm device of a prior art structure can be installed at lock box (1), the metal part timesharing as the people runs into lock body just triggers wireless alarm system and reports to the police. Locking bolt (10) reciprocatingly sliding on guide rail (14) can be adopted other common easy structure in the guide frame of traditional dovetail groove, wedge or the prior art.

Operation principle of the present utility model and process are, handle described emitter (18), control driving power (15) after its signal that sends is received by receiver (5) and make the line shaft of reversible motor (2) do the rotation of respective direction (forward or send out and turn to), gear driving rack on it (4) translation and make that locking bolt (10) is whole to be moved back and forth accordingly, be locking bolt (10) when moving to the precalculated position, just touch limit switch (9) or (13) and reversible motor (2) is quit work; Since lock box (1) and bolt box (3) be installed in respectively two fan doors upper or univalve doors and with doorframe (body of wall) on, the locking that said process has just been realized or the unlatching of door lock. After locking bolt (10) arrived latched position, the hook end of gravity auxiliary catch (8) namely fell into groove (11) according to gravity, and locking bolt (10) can not be slided again; When unblanking, electromagnet (7) is switched on earlier by instruction and will be moved iron core and mention, and gravity auxiliary catch (8) hook end is releasing slots (11) thereupon mentioning, and motor (2) action makes locking bolt (10) move to left, unblank. Device must can be switched on behind the input cipher instruction and be made relevant parts action, and theftproof performance is good.

As known from the above, the utility model has realized that employing motor drive gear rackwork is real The movement of existing locking bolt, and the positive and negative rotation of shaking controlled motor are the significant antitheft no key locks of practicality, are suitable for the uses such as various warehouse gates, traffic gate. It is simple in structure, theftproof performance good, easy to use.

Embodiment: put according to opening of structure shown in the accompanying drawing, adopt common frequency modulation emission of 82 to 108 megahertzes, two channels and receiver (18) (5), effectively emission, 30 meters of receiving ranges, relevant structural member adopts steel to make, and wherein locking bolt (10) length is 60 centimetres, 12 centimetres of strokes (tooth bar length), sectional dimension is 20 * 30 millimeters, and reversible electronic (2) are 30 watts of slowspeed machines.
