Description
Technical field
The utility model relates to a kind of lock, particularly a kind of electric control lock that is used for the communication cable cross-connecting box.
Background technology
Along with the development of telecommunications industry, the quantity of communication cable cross-connecting box is also increasing sharply, and shows the safety problem day of cross-connecting box outstanding.Existing communication cable cross-connecting box uses mechanical lock mostly, for safety, has the people to be provided with Cipher mechanism or the special-purpose key of employing on the structure of lock.Disclose a kind of cable distribution box lock pin control device as Chinese patent CN2319512, it mainly forms its structure more complicated, complex operation by tongue bar, bent tongue bar and dialer formula lock pin control mechanism.Chinese patent CN 2685481 discloses another kind of cable distribution box lock, be lockhole to be designed to special shapes such as triangle, rectangle, for many unserviced outdoor cross-connecting boxes, this class lock still can not solve safety problem, particularly shockproof, sled poor-performing.In recent years, also there is the people that common electric control lock is used for cable distribution box, the dead bolt part and the lock body part of these electric control locks hold together, be fixed in the shell, and be installed on the same door leaf, its dead bolt adopts vertical hook-shaped or linear telescopic dead bolt, lock body part is provided with drive plate and locking bar, locking bar stretches out outside the lock body, is used to compress the spring that produces driving force, just has to the flexible dead bolt of both direction as the disclosed intelligent electronic lock of Chinese patent CN2545304.The existing problem of this class cross-connecting box electric control lock is: the easy displacement of dead bolt under the shake of external force is struck or clashed into and throwing off, and lock body and dead bolt are connected as a single entity, so easily cause being out of shape and lock body in damage of components.
Summary of the invention
Problem to be solved in the utility model is: at existing in prior technology the problems referred to above, provide a kind of shockproof good, safe electric control lock that is exclusively used in the communication cable cross-connecting box of performance that strikes.
The technical scheme that addresses the above problem is: the electric control lock of the communication cable cross-connecting box that is provided comprises lock body part, dead bolt part and shell, lock body part and shell are connected as a single entity and are installed on the Yishanmen of cross-connecting box, said lock body part has the locking bar of drive plate and compressible drive spring, and this locking bar stretches out outside the lock body.Improvements of the present utility model are: said dead bolt partly is installed on the Yishanmen in addition of communication cable cross-connecting box; Said outer casing inner wall is provided with and the corresponding locking groove in dead bolt termination; Said dead bolt partly comprises the dead bolt seat, is positioned at the dead bolt and the dead bolt back-moving spring of dead bolt seat guide chute, and the dead bolt afterbody is provided with the unidirectional coupling mechanism that links with aforementioned drive plate; At locking states, dead bolt partly is inclusive in the aforesaid shell, and the dead bolt seat is pressed to the precalculated position with the locking bar of aforementioned compressible drive spring, and the dead bolt termination extend into the locking of outer casing inner wall with in the groove.
When cross-connecting box was opened, the dead bolt part was separated with lock body part, laid respectively at two fan doors; When cross-connecting box was closed, dead bolt was inserted under the effect of back-moving spring in the locking groove of shell, and the dead bolt seat is got ready for unblanking by locking bar compressible drive spring; When unblanking, drive plate drives the dead bolt retraction by unidirectional coupling mechanism, leaves the locking groove.
Above-mentioned dead bolt afterbody is meant that with the unidirectional coupling mechanism that drive plate links drive plate just is connected with dead bolt when a direction is moved, and drives dead bolt with contracting, and the elastic force of back-moving spring is then leaned in the opposite direction motion of dead bolt.
Above-mentioned unidirectional coupling mechanism can be made up of the slotted eye on dead bolt pintle and the drive plate, and this pintle inserts in the aforesaid slotted eye; Also can be made up of the barb on dead bolt pintle and the drive plate, this dead bolt pintle and drive plate barb are together in interleaved relation with each other.
Compared with prior art, the utility model separates the dead bolt part with lock body part, make dead bolt form a chain structure to the transmission between electromagnetism or the electronic source, and branch is located on the two fan doors, so anti-collision, shockproof ability of striking are strong, and at external force shake, part when hitting in the not fragile lock body; In addition, locking groove of the present utility model is arranged on outer casing inner wall, so the pick-proof performance is good.
Description of drawings
Fig. 1 is the structural representation of an embodiment of the utility model.
Fig. 2 is the driving mechanism schematic diagram of lock body part among Fig. 1.
The specific embodiment
An embodiment of the present utility model as shown in Figure 1 and Figure 2.Dead bolt part 1 is made up of dead bolt 11, dead bolt seat 12, back-moving spring 16 and cover plate 13, and dead bolt 11 is positioned at the chute that is surrounded by dead bolt seat 12 and cover plate 13, and the front end of dead bolt is dead bolt termination 14, and afterbody has pintle 15.Lock body part 2 is connected as a single entity with shell 3, and dead bolt part 1 and lock body part 2 are installed in respectively on the two fan doors of cross-connecting box.Lock body part 2 is provided with drive plate 21, rocking arm 22, stop rocking arm 23, stretches out lock body outer locking bar 24, driving spring 25,26 and electromagnet 27 etc.Dead bolt pintle 15 is a right angle hook, and the right angle barb 28 of it and drive plate 21 front ends is in interleaved relation with each other, that is, can drive dead bolt 11 when drive plate 21 moves to right and move to right.
When cross-connecting box two fan doors were closed, dead bolt part 1 was positioned at shell 3, and its dead bolt termination 14 is inserted into the locking of shell 3 inwalls with in the groove 31; Simultaneously, dead bolt seat 12 pushing locking bars 24, two driving springs 25,26 of compression when locking bar 24 moves are because stop rocking arm 23 by rocking arm 22 lockings, is blocked by stop rocking arm 23 behind the segment distance so drive plate 21 moves to right.Electromagnet 27 energisings when unblanking, attract rocking arm 22 right-hand members to move down, untie locking to stop rocking arm 23, drive plate 21 moves to right under the effect of driving spring 25,26, drive dead bolt 11 and move to right, make dead bolt termination 14 leave the locking groove 31 of shell, its state as shown in phantom in FIG., at this moment, can open the door of cross-connecting box.
