Description

Fiber cable cross connection box door knob device

Technical field

The present invention relates to smart lock technical field, specifically the lock core of smart lock for a kind of fiber cable cross connection box.

Background technology

Fiber cable cross connection box (is called for short: optical cross box) almost ubiquitous in whole fiber optic network.Along with the propelling of China Mobile's full-service district and FTTH building-up work, the building-up work of Metropolitan Area Network (MAN) optical cross box is raised speed, and annual increment is more than 30%.As can be seen here, the necessity of optical cross box in whole basic network is self-evident.

Along with the generally setting of optical cross box, the security of operation of optical cross box and box equipment has become most important work in management.Optical cross connects chamber door needs the position that opposite house closes to limit when closing, and therefore door knob device need to be set.In prior art, door knob device is generally in the upper and lower edge of cabinet doorframe or side frame place arranges projection or raised line to realize the spacing of opposite house.This projection or raised line protrude to doorframe inner side, and when staff overhauls handing-over box equipment, these projections or raised line often or head or other position of health of the staff that collides with, even cause the soft tissue bruise of staff's health; Meanwhile, the projection or the raised line that to doorframe inner side, protrude, also limited staff's scope of activities, also can make a little bigger equipment replacement difficulty when changing handing-over box equipment.How to make to stretch out doorframe at door knob device at closing time, when opening the door, making door knob device retract becomes the key addressing this problem.

Summary of the invention

For the above-mentioned technical problem existing in prior art, the present invention proposes a kind of fiber cable cross connection box door knob device.

The technical solution used in the present invention is: a kind of fiber cable cross connection box door knob device, comprise be arranged at a upper edge plush copper, be arranged at cabinet body door upper frame edge along locating and the grammed switch of plush copper opposite position and the controlled door knob performance element that is arranged at cabinet doorframe side edge, the control input end of the output of described grammed switch and controlled door knob performance element is electrically connected.Described controlled door knob performance element comprises housing, guide groove, door knob tongue and direct current generator; In described housing sidewall, have door knob tongue telescopic hole, described door knob tongue can by this door knob tongue telescopic hole stretch out retraction housing outer or in; Described guide groove comprises two, is arranged on the both sides of the door knob tongue direction of motion, coordinates with door knob tongue; Described door knob tongue latter half is provided with tooth bar; On the output shaft of described direct current generator, by pin, be fixedly installed gear, wheel and rack engagement.

As optimal way, described tooth bar and door knob tongue integrated setting.

Further, in described controlled door knob performance element, be also fixedly installed power management module, the power output end of described power management module and the power input of direct current generator are electrically connected.Concrete, also comprising a direct current motor drive module, the input of this direct current generator driver module and the power output end of power management module are electrically connected, and the power input of output and direct current generator is electrically connected.

The beneficial effect that technical solution of the present invention can realize: when door is closed, plush copper is touched grammed switch, controls direct current generator forward/reversion, drives door knob tongue to stretch out housing, and opposite house carries out spacing; When door is opened, plush copper does not contact with grammed switch, controls direct current generator reversion/forward, drives door knob tongue retraction housing.Solve prior art and be fixedly installed the problem that door knob structure is brought.

Accompanying drawing explanation

Fig. 1 is the structural representation of door knob device for embodiment of the present invention fiber cable cross connection box.

Fig. 2 is the cross-sectional view of controlled door knob performance element shown in embodiment of the present invention Fig. 1.

The specific embodiment

Below in conjunction with accompanying drawing, the embodiment of the present invention is described in detail.

As depicted in figs. 1 and 2.Fiber cable cross connection box comprises cabinet 1, and the door 2 on cabinet 1 is set, and described door 2 is arranged on the doorframe side of cabinet 1 by hinge 3.A kind of fiber cable cross connection box door knob device of the present embodiment, comprise be arranged at door 2 upper edges plush copper 4, be arranged at cabinet 1 doorframe upper edge place and the grammed switch 5 of plush copper 4 opposite positions and the controlled door knob performance element 6 that is arranged at cabinet 1 frame side edge, the control input end electric connection of the output of described grammed switch 5 and controlled door knob performance element 6.Described controlled door knob performance element 6 comprises housing 61, guide groove 64, door knob tongue 62 and direct current generator 63; On described housing 61 sidewalls, have door knob tongue telescopic hole, described door knob tongue 62 can by this door knob tongue telescopic hole stretch out retraction housing 1 outer or in; Described guide groove 64 comprises two, is arranged on the both sides of door knob tongue 62 directions of motion, coordinates with door knob tongue 62, and these two guide grooves 64, can limit location more accurately to the operating provisions of door knob tongue, prevent the dislocation of door knob tongue in motion process; Described door knob tongue 62 latter halfs are provided with tooth bar 621; On the output shaft of described direct current generator 63, by pin, be fixedly installed gear 631, gear 631 and tooth bar 621 engagements.
