During actual use, the fixing lock 200 of described keeper formula is installed on switch cabinet panel, for latch switch cabinet cabinet door, on cabinet door, be provided with lock nose, lock nose is provided with perforate, the perforate that the 205a of dead bolt portion of locking bolt 205 inserts on lock nose is lockable cabinet door, and the perforate that the 205a of dead bolt portion of locking bolt 205 leaves on lock nose can be separated locker door.Below the operating principle of the fixing lock 200 of the keeper formula in the present embodiment and key thereof is described:
Under blocking (as shown in Figure 3), the first spacing preiection 206a of the first latch shaft 206 is stuck in the first limited impression 205c of locking bolt 205 locking bolt 205 can not be moved under the elastic force effect of the second elastomeric element 202, thereby reach locking object, now latch release shaft 208 under the first latch shaft 206 drives in initial position.Simultaneously, lock nose on cabinet door is pushed down and is driven bolt 204 that it is shunk, and drives the inclined-plane of the bolt 204 voussoir 204a elastic force that forces the second latch shaft 207 to overcome backward the 3rd elastomeric element 203 that slides on the 207b of inclined plane to leave the second limited impression 205d on locking bolt 205.
As shown in Figure 4, during release, the trip lever 101 of key 100 inserts in unlock hole 211a, the in-line groove 101a of trip lever 101 front ends coordinates with the in-line projection 208b of latch release shaft 208 tail ends, the opening of guide groove 101b on trip lever 101 outer peripheral faces is aimed at spacer pin 209, clockwise rotate key 100, the in-line groove 101a of trip lever 101 front ends drives the in-line projection 208b of latch release shaft 208 tail ends together to rotate, the eccentric shaft 208a of latch release shaft 208 front ends drives the first latch shaft 206 to overcome the second elastomeric element 202 elastic force and moves away backward locking bolt 205, locking bolt 205 outwards ejects under the first elastomeric element 210 effects, the release of cabinet door.After locking bolt 205 ejects, the first latch shaft 206 is blocked and can not be advanced by locking bolt 205, thereby make latch release shaft 208 can not rotate backward reset, and the limited pin 209 of the guide groove 101b of key side blocks it can not be extracted, thereby having realized key after release cannot take out, only after fixing lock 200 again locking, key just can be taken away, guarantees that release and locking flow process are correct and facilitates release and lock operation.
During locking, close Over-The-Counter door, lock nose on cabinet door is pushed down and is driven bolt 204, drive the inclined-plane of the bolt 204 voussoir 204a elastic force that forces the second latch shaft 207 to overcome backward the 3rd elastomeric element 203 that slides on the 207b of inclined plane to leave the second limited impression 205d on locking bolt 205, thus release locking bolt 205; Press latch buttons 201, the first latch shaft 206 forward gear under the first elastomeric element 210 elastic force effects makes its locking in locking bolt 205 first limited impression 205c by hand; Meanwhile, the first latch shaft 206 drives latch release shaft 208 to rotate counterclockwise, and the in-line projection 208b of latch release shaft 208 tail ends drives key to get back to after initial position, and key can take off.
As can be seen here, the fixing lock of keeper formula in the present embodiment is owing to having adopted said structure, after release, key cannot take out, only after fixedly locking locking again, key just can be taken away, thereby avoided key after release to omit in cabinet door, and guaranteed release and locking flow process correctly and facilitate release and lock operation.
The above embodiment has only expressed several embodiment of the present utility model, and it describes comparatively concrete and detailed, but can not therefore be interpreted as the restriction to the utility model the scope of the claims.It should be pointed out that for the person of ordinary skill of the art, without departing from the concept of the premise utility, can also make some distortion and improvement, these all belong to protection domain of the present utility model.
