Utility model content
For the problems referred to above that prior art exists, the purpose of this utility model is the door latch structure providing the highly reliable Intelligent low-voltage power distribution cabinet of a kind of modularization.
The door latch structure of the highly reliable Intelligent low-voltage power distribution cabinet of a kind of modularization, comprise tapered end, described tapered end is provided with the keyhole for inserting key being exposed to tapered end surface, described keyhole is arranged on lock core, outer shaft is provided with below described tapered end, described tapered end can rotate around the axis of outer shaft, and described outer shaft is connected with away from one end of tapered end and can rotates around outer shaft axis and clamp for blocking or unclamp cabinet door.
Preferably, also comprise drive disk assembly, described drive disk assembly comprises cam, one end of described lock core is connected with cam and rotates for the lock core rotating band moving cam when keyhole inserts key, described cam is tangentially provided with roller along on its periphery, described roller connects one end of push rod, described in connect push rod the other end be hinged on rotating disk, described rotating disk and clamp are coaxially installed and are driven clamp to rotate.
Preferably, described outer shaft is coaxially installed with external gear, and described external gear engagement internal gear, described internal gear coaxially installs lock core for driving cam, can live or unclamp cabinet door by driver card board when described outer shaft is rotated.
Preferably, be positioned on described tapered end and described keyhole is provided with the dust ring for hindering dust to enter.
Preferably, described outer shaft is provided with external thread section, one end of described external thread section is provided with nut.
In sum, the utility model has the following advantages:
The utility model inserts the rotation after key by tapered end or lock core, can drive the rotation of clamp, and then realizes opening or closing of cabinet door for power distributing cabinet.And by optimizing the vibrational power flow of drive disk assembly, smooth when making transmission, not easily clamping stagnation, has again maintainable preferably simultaneously.
Accompanying drawing explanation
Fig. 1 is the schematic perspective view of the utility model embodiment;
Fig. 2 is the front view of the utility model embodiment;
Fig. 3 is the structural representation of the drive disk assembly of the utility model embodiment.
Detailed description of the invention
Do to illustrate in detail, intactly further to the utility model below in conjunction with embodiment and accompanying drawing.
As Figure 1-3, the door latch structure of the highly reliable Intelligent low-voltage power distribution cabinet of a kind of modularization, comprise tapered end d1, described tapered end d1 is provided with the keyhole d2 for inserting key being exposed to tapered end d1 surface, and described keyhole d2 is arranged on lock core d3, is provided with outer shaft d4 below described tapered end d1, described tapered end d1 can rotate around the axis of outer shaft d4, and described outer shaft d4 is connected with away from one end of tapered end 1 and can rotates around outer shaft d4 axis and clamp d5 for blocking or unclamp cabinet door.
Preferably scheme, also comprise drive disk assembly, described drive disk assembly comprises cam d6, one end of described lock core d3 is connected with cam d6 and rotates for the lock core d3 rotating band moving cam d6 when keyhole d2 inserts key, described cam d6 is tangentially provided with roller d71 along on its periphery, described roller d71 connects one end of push rod d72, described in meet push rod d72 the other end be hinged on rotating disk d8, described rotating disk d8 and clamp d5 coaxially installs and drives clamp d5 to rotate.Described outer shaft d4 is coaxially installed with external gear d41, and described external gear d41 engages internal gear d42, and described internal gear d42 coaxially installs lock core d3 for driving cam d6, clamp d5 can be driven to block or unclamp cabinet door when described outer shaft d4 is rotated.
Preferably scheme, is positioned on described tapered end d1 and described keyhole d2 is provided with the dust ring d11 for hindering dust to enter.Described outer shaft d4 is provided with external thread section d43, and one end of described external thread section d43 is provided with nut d9.
It is comparatively roomy that tapered end d1 can design under normal conditions, be convenient to people's hand operation, like this then tapered end d1 is equivalent to the effect of so-called handle, after rotational lock head d1, tapered end d1 drives external gear d41 to rotate, external gear d41 drives internal gear d42 to rotate, internal gear d42 is with moving cam d6 to rotate, cam d6 pushing rolling wheels d71 is along its surface scrolls, realize the reducing motion of roller d71, roller d71 promotes push rod d72, push rod d72 does reciprocating, push rod d72 promotes rotating disk d8, rotating disk d8 and clamp d5 coaxially installs and drives clamp d5 to rotate subsequently, clamp d5 can be driven to block or unclamp cabinet door when described outer shaft d4 is rotated.Similarly after inserting keyhole d2 with key, cam d6, roller d71, push rod d72 and rotating disk d8 repeat above-mentioned action, clamp d5 is blocked or unclamps cabinet door.So can open the lock with the key, also can unblank with the action of tapered end d1, easy and simple to handle, smooth.Due to this door lock, be generally used on the inside door of power distribution cabinet, thus without the need to considering anti-theft function, topmost during convenient operation.
