Abstract

Electromagnetic lock machinery unlocking device. The parts that belong to electromagnetic lock for the high tension switchgear. Characterized by: including the lock shell, locking closure and hasp, available L shape spring bolt is opened or closes to the cooperation locking closure, electro -magnet and electro -magnet lock, the upper end joins in L shape spring bolt lower part and cooperates in the post that pushes away of electro -magnet lock lower extreme, cup joint the pressure spring on the electro -magnet lock, the lockhole is separated to the electronics key, characterized by still separates the lockhole including the machinery that lies in on the locking closure, coordinate the mechanical lock core that is equipped with in the lockhole is separated to machinery, bind in the unblock plectrum on mechanical lock core top, the mounted position of unblock plectrum is touched in L shape spring bolt upper end and is made the spring bolt upper end withdraw from from the hasp for satisfying its head cooperation, and mechanical full unlock keys. Through on probation, there is mechanical unlocking device's prior art to compare with design not, shown when the electronics key is malfunctioning, can further adopt mechanical full unlock keys to open the electromagnetic lock to satisfy and adapted to the needs that the electromagnetic lock was unblanked the back operation or was maintained.

Description

Electromagnetic lock mechanical release device

Technical field: the utility model belongs to the parts of high voltage switchgear equipment electromagnetic lock, particularly a kind of electromagnetic lock mechanical release device.

Background technology: in the electromagnetic lock of existing high voltage switchgear equipment, there is a kind of electromagnetic lock being equipped with electron key, it, in actual use when electron key is malfunctioning, just cannot open the locking closure of electromagnetic lock, thus the needs of operation or maintenance after cannot adapting to electromagnetic lock unlocking.

As can be seen here, study and design a kind of when electron key is malfunctioning, the electromagnetic lock mechanical release device that mechanical release key can be adopted further to open is necessary.

Utility model content: the purpose of this utility model overcomes the deficiencies in the prior art, studies and designs a kind of when electron key is malfunctioning, can adopt the electromagnetic lock mechanical release device that mechanical release key is opened further.

The technical scheme realizing the utility model object is: a kind of electromagnetic lock mechanical release device, comprise lock housing, lock housing top can the locking closure of folding and snap close, coordinate the L shape dead bolt that locking closure is opened or closed, be configured at electromagnet and the electromagnet lock of lock housing inside, upper end be linked in L shape dead bolt bottom and be matched with electromagnet lock lower end push away post, be socketed on the stage clip on electromagnet lock, be electrically connected in the electron key unlock hole of electromagnet, it is characterized in that also comprising the mechanical release hole be positioned on locking closure, be matched with the mechanical lock be provided with in mechanical release hole, be linked in the unblock plectrum on mechanical lock top, the installation site of described unblock plectrum is touched in L shape dead bolt upper end for meeting its head fits and dead bolt upper end is exited from snap close, for opening mechanical lock and unlocking the mechanical release key of plectrum together with rotating.

The purpose of this utility model can also take following further technical measures to realize: described in push away post lower end through the through hole of lock housing bottom.

The electromagnetic lock mechanical release device operating process that the utility model is implemented to obtain is as follows:

What manually upwards overcome the resilient force lock housing bottom of the stage clip on electromagnet lock while locking closure is pressed in manual operation pushes away post, must drive be linked in push away post upper end L shape dead bolt upwards, L shape dead bolt upper end is made to enter the snap close on lock housing top, locking closure is pinned, now by means of the electromagnetic adsorption power of electromagnet lock, L shape dead bolt upper end is kept to enter the locking states of the snap close on lock housing top, as shown in Figure 1, 2; When using electron key to insert electron key unlock hole, electromagnet coil dead electricity, the electromagnetic adsorption power of absorption electromagnet lock disappears, order about under the elastic restoring force of stage clip promotes and push away post upper end and move down, drive L shape dead bolt downward, the L shape dead bolt upper end entering the snap close on lock housing top is and then called in the following text and is exited from snap close, so locking closure is opened, as shown in Figure 4,5;

If so, electron key is malfunctioning after inserting electron key unlock hole, and electromagnet coil is dead electricity not, continue to keep the electromagnetic adsorption to electromagnet lock, L shape dead bolt upper end also still keeps the locking states entering the snap close on lock housing top, as shown in Figure 1, 2, namely cannot open; In order to the needs of operation or maintenance after satisfied adaptation electromagnetic lock unlocking, mechanical release key of the present utility model is adopted to insert unlock hole, the unblock plectrum on rotational lock core and top thereof, touch in L shape dead bolt upper end because the installation site unlocking plectrum meets its head fits and make the condition that dead bolt upper end is exited from snap close, use mechanical release key L shape dead bolt upper end will be forced to exit from snap close, so locking closure is opened as shown in Figure 4,5 when turning to and touching in L shape dead bolt upper end.

The utility model implements the electromagnetic lock mechanical release device obtained, through on probation, as mentioned above, compared with not being designed with the prior art of mechanical release device, when electron key is malfunctioning, mechanical release key can be adopted further to open electromagnetic lock, thus meet the needs having adapted to operation after electromagnetic lock unlocking or safeguarded.

Accompanying drawing illustrates: Fig. 1 is the forward schematic diagram of the locking closure meeting the utility model thematic structure when closing; Fig. 2 is the side schematic view of the locking closure meeting the utility model thematic structure when closing; Fig. 3 is the mechanical release Key structure schematic diagram meeting the utility model thematic structure; Fig. 4 is the forward schematic diagram of the locking closure meeting the utility model thematic structure when opening; Fig. 5 is the side schematic view of the locking closure meeting the utility model thematic structure when opening.

Detailed description of the invention: implementation detail of the present utility model is described as follows below in conjunction with accompanying drawing:

As Figure 1-5, a kind of electromagnetic lock mechanical release device, comprise lock housing 1, lock housing top can folding locking closure 2 and on snap close 21, locking closure 2 is coordinated to open or closed L shape dead bolt 3, be configured at electromagnet 4 and the electromagnet lock 41 of lock housing 2 inside, upper end be linked in L shape dead bolt 3 bottom and be matched with electromagnet lock 41 lower end push away post 5, be socketed on the stage clip 6 on electromagnet lock 41, be electrically connected in the electron key unlock hole 7 of electromagnet 4, it is characterized in that also comprising the mechanical release hole 22 be positioned on locking closure 2, be matched with the mechanical lock 8 be provided with in mechanical release hole 22, be linked in the unblock plectrum 81 on mechanical lock 8 top, the installation site of described unblock plectrum 81 is touched in L shape dead bolt 3 upper end for meeting its head fits and dead bolt 3 upper end is exited from snap close 21, for opening mechanical lock 8 and unlocking the mechanical release key 9 of plectrum 81 together with rotating.

As shown in Fig. 1,2,4,5, described in push away post 5 lower end through the through hole 11 of lock housing bottom.The technique effect of this design is the manual operation be convenient to when being closed by locking closure.
