Abstract
The invention provides a ZH-MD190 cabinet convenient door lock. The ZH-MD190 cabinet convenient door lock comprises a door lock body arranged on a cabinet door and a door lock support fixedly arranged on a column and adapted with the door lock body. According to the ZH-MD190 cabinet convenient door lock, an outside thread is cancelled, and the door lock is divided into the door lock body and the door lock support. According to the door lock body, the outside thread is cancelled, and the door lock body is divided into a lock handle and a lock pin. When a door is closed, the lock pin part directly passes through a circular hole of the door lock support when passing, after rotating for 90 DEG, the lock pin part is blocked between two pair of spacing bosses in the circular hole of the door lock support, hence the door is locked and is not naturally opened. When the door is opened, the lock pin part rotates for 90 DEG, and strides the spacing bosses by means of outside force, after the lock pin is arranged horizontally, a door plate is opened. Structure is simple and the door lock is convenient and practical.
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 claims again low-tension switch cabinet, and it is applicable to transformer station, power plant, industrial and mining enterprises etc.Be to exchange 50Hz, the distribution system of rated voltage 380v, as power, is thrown light on and the electric energy conversion of distribution and the use of control.It is strong that this product has breaking capacity, and dynamic thermal stability is good, and electric scheme is drawn flexibly, combined and instant, series, practical, the features such as novel structure.
Door lock is one of important component part of low-tension switch cabinet, in the direct precession special-purpose section of the screw thread on door lock, conventionally in a cabinet, there is more than 3 door locks, cabinet is when complete installation, need to correspondingly open one by one, after installing, also need precession one by one to lock.This door lock of the prior art has increased the intensity of operation, uses very inconvenient.
Summary of the invention
In order to address the above problem, the invention provides a kind of ZH-MD190 cabinet convenient door lock, comprise the door lock body that is arranged on cabinet door and be fixedly mounted on column with the suitable door lock support of described door lock body, it is characterized in that,
Described door lock body comprises 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, on described lock pin outer surface, be provided with into axisymmetric the 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 passes the hollow space of described lock pin and penetrates in the front end of described shank of the key, thereby described shank of the key and described lock pin are fixedly installed togather;
Described door lock support comprises rack body, and described rack body is one-body molded by front side board, back side panel and right plate, wherein, on described back side panel, be provided with an installing hole, and thering is the anti-rotation limit of a bending, described front side board middle part is provided with a circular hole, is provided with 4 positive stop lug boss in described circular hole.
Preferably, 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.
The beneficial effect that invention has is:
ZH-MD190 cabinet convenient door lock of the present invention, cancel external screw thread, be divided into door lock body and door lock support, door lock body part is cancelled external screw thread, be divided into shank of the key and lock pin, at closing time, by time lock pin part directly pass in door lock support circular hole, after 90-degree rotation, be stuck between 2 pairs of positive stop lug boss in door lock support circular hole, thereby locking can not opened again naturally.While opening, 90-degree rotation, strides across positive stop lug boss by external force again, and after lock pin becomes a word horizontally, door-plate is opened, simple in structure, convenient and practical.

Embodiment
Below in conjunction with Figure of description, the present invention is done to further detailed introduction.
Fig. 1 is the door latch structure schematic diagram of convenient door lock for ZH-MD190 cabinet of the present invention; Fig. 2 is the detent configuration schematic diagram in convenient door lock for ZH-MD190 cabinet of the present invention; Fig. 3 is the structural representation of the door lock support in convenient door lock for ZH-MD190 cabinet of the present invention; Fig. 4 is the scheme of installation of convenient door lock for ZH-MD190 cabinet of the present invention.As shown in Figure 1 to Figure 3, ZH-MD190 cabinet convenient door lock of the present invention, comprise the door lock body 1 being arranged on cabinet door and be fixedly mounted on column with the suitable door lock support 2 of described door lock body.
Wherein:
Described door lock body 1 comprises shank of the key 11 and lock pin 12, described shank of the key 11 front ends have a groove, the cylinder that described lock pin 12 is hollow, on described lock pin 12 outer surfaces, be provided with into axisymmetric the 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 passes the hollow space of described lock pin 12 and penetrates in the front end of described shank of the key 11, thereby described shank of the key 11 and described lock pin 12 are fixedly installed togather;
Described door lock support 2 comprises rack body 21, described rack body is one-body molded by front side board 211, back side panel 212 and right plate 213, wherein, on described back side panel 212, be provided with an installing hole 212a, and there is the anti-rotation limit 212b of a bending, described front side board 211 middle parts are provided with a circular hole 211a, are provided with 4 (being also 2 couples) positive stop lug boss 211b in described circular hole 211a.
While installing and using, first door lock support 2 is fixed on column 4 by countersunk self-tapping screw 3.Then, the protuberance 12c of lock pin 12 is aimed to the groove of shank of the key 11, more fixing to shank of the key 11 from lock pin 12 with screw 13, thus an integral body be linked to be.Closing the door, time lock pin 12 directly through in door lock support 2 circular holes, after 90-degree rotation, the first guide part 12a and the second guide part 12b are stuck between 2 couples of positive stop lug boss 211b of door lock support 2, thus locking can not opened again naturally.While opening, by door lock body 1 90-degree rotation again, by external force, stride across positive stop lug boss 211b, 12 one-tenth one words of lock pin horizontally after, door-plate can be opened.
