Description
Technical field
The present invention relates to low-voltage distribution cabinet technical field, particularly relate to a kind of ZH-MD190 cabinet convenient door lock。
Background technology
Low-voltage distribution cabinet is also known as low-tension switch cabinet, and it is applicable to transformer station, power plant, industrial and mining establishment etc.。It is that the distribution system of exchange 50Hz, rated voltage 380v is as power, the electric energy conversion of illumination and distribution and the use of control。It is strong that this product has breaking capacity, the features such as dynamic thermal stability is good, and electrical arrangement draws flexibly, and combined and instant is serial, practical, novel structure。
Door lock is one of important component part of low-tension switch cabinet, by, in the direct precession special-purpose section of the screw thread on door lock, generally having the door lock of more than 3 in a cabinet, cabinet is when complete installation, need to open one by one accordingly, be also required to precession one by one after installing and lock。This door lock of the prior art increases the intensity of operation, uses very inconvenient。
Summary of the invention
In order to solve the problems referred to above, the invention provides a kind of ZH-MD190 cabinet convenient door lock, including the door lock body being arranged on cabinet door and the latch bracket suitable with described door lock body being fixedly mounted on column, it is characterised in that
Described door lock body includes shank of the key and lock pin, described shank of the key front end has a groove, described lock pin is the cylinder of hollow, described lock pin outer surface is provided with into axisymmetric first guide part and the second guide part, and the rear end of described lock pin has the protuberance suitable with described groove, one screw is through the hollow space of described lock pin and in penetrating the front end of described shank of the key, thus described shank of the key and described lock pin being fixedly installed togather；
Described latch bracket includes rack body, and described rack body is one-body molded by front side board, back side panel and right plate, wherein, described back side panel is provided with an installing hole, and there is the anti-rotation limit of a bending, it is provided with a circular hole in the middle part of described front side board, in described circular hole, is provided with 4 positive stop lug boss。
It is preferred that described back side panel is fixed on described column by countersunk self-tapping screw, and the opposite side of described column is close on described anti-rotation limit。
Invention is had the beneficial effect that
The ZH-MD190 cabinet convenient door lock of the present invention, cancel external screw thread, it is divided into door lock body and latch bracket, door lock body part cancels external screw thread, be divided into shank of the key and lock pin, at closing time, by time latch portion directly through in latch bracket circular hole, locking it is stuck in after 90-degree rotation between 2 pairs of positive stop lug boss in latch bracket circular hole, thus will not be opened again naturally。When opening, 90-degree rotation again, stride across positive stop lug boss by external force, after lock pin becomes a word horizontally arranged, door-plate is opened, simple in construction, convenient and practical。

Detailed description of the invention
Below in conjunction with Figure of description, the present invention done further details of introduction。
Fig. 1 is the door latch structure schematic diagram of the ZH-MD190 cabinet convenient door lock of the present invention；Fig. 2 is the detent configuration schematic diagram in the ZH-MD190 cabinet convenient door lock of the present invention；Fig. 3 is the structural representation of the latch bracket in the ZH-MD190 cabinet convenient door lock of the present invention；Fig. 4 is the scheme of installation of the ZH-MD190 cabinet convenient door lock of the present invention。As shown in Figure 1 to Figure 3, the ZH-MD190 cabinet convenient door lock of the present invention, including the door lock body 1 being arranged on cabinet door and the latch bracket 2 suitable with described door lock body being fixedly mounted on column。
Wherein:
Described door lock body 1 includes shank of the key 11 and lock pin 12, described shank of the key 11 front end has a groove, described lock pin 12 is the cylinder of hollow, described lock pin 12 outer surface is provided with into axisymmetric first guide part 12a and the second guide part 12b, and the rear end of described lock pin 12 has the protuberance 12c suitable with described groove, one screw 13 is through the hollow space of described lock pin 12 and in penetrating the front end of described shank of the key 11, thus described shank of the key 11 and described lock pin 12 being fixedly installed togather；
Described latch bracket 2 includes rack body 21, described rack body is one-body molded by front side board 211, back side panel 212 and right plate 213, wherein, described back side panel 212 is provided with an installing hole 212a, and there is the anti-rotation limit 212b of a bending, it is provided with a circular hole 211a in the middle part of described front side board 211, in described circular hole 211a, is provided with 4 (namely 2 couples) positive stop lug boss 211b。
When installing and using, first latch bracket 2 is fixed on column 4 by countersunk self-tapping screw 3。Then, the protuberance 12c of lock pin 12 is directed at the groove of shank of the key 11, then fixes to shank of the key 11 from lock pin 12 with screw 13, thus being linked to be an entirety。Closing the door, time lock pin 12 directly through in latch bracket 2 circular hole, after 90-degree rotation, the first guide part 12a and the second guide part 12b is stuck between 2 couples of positive stop lug boss 211b of latch bracket 2, thus locking will not naturally open again。When opening, by door lock body 1 90-degree rotation again, stride across positive stop lug boss 211b by external force, after lock pin 12 one-tenth one word is horizontally arranged, door-plate can be opened。
In sum, the ZH-MD190 cabinet convenient door lock of the present invention, cancel external screw thread, being divided into door lock body and latch bracket, door lock body part cancels external screw thread, is divided into shank of the key and lock pin, at closing time, by time latch portion directly through, in latch bracket circular hole, being stuck in after 90-degree rotation between 2 pairs of positive stop lug boss in latch bracket circular hole, thus locking will not naturally open again。When opening, 90-degree rotation again, stride across positive stop lug boss by external force, after lock pin becomes a word horizontally arranged, door-plate is opened, simple in construction, convenient and practical。
Disclosed above is only specific embodiments of the invention, and this embodiment is only used by the clearer explanation present invention, and is not limitation of the invention, and the changes that any person skilled in the art can think of all should drop in protection domain。
