Detailed Description
Referring to fig. 1, a safety type switch cabinet according to the present invention employs a safety door lock including: the base 1, a plurality of bracing pieces 2, backup pad 3, axle core 4, spring bolt 5, push away portion 6, inserted bar 7, spring plate 8, drive plate 9, drive wheel 10 and support 11.
The backup pad 3 is installed in base 1 top through many spinal branch vaulting poles 2 level, and axle core 4 rotates to be installed on backup pad 3, and spring bolt 5 is installed on axle core 4 and rotates with axle core 4 synchronization. The safety door lock realizes unlocking and locking functions through rotation of the lock tongue 5, a lock hole 17 for inserting a key is formed in the shaft core 4, and the shaft core 4 and the lock tongue 5 can rotate through a key belt after the key is inserted.
The spring plate 8 is mounted on the base 1 by a spring 15 and slides in the direction of the lock hole in the shaft core 4. Thus, when the key is inserted into the lock hole, the spring 15 can be compressed by pushing the spring plate 8 through the key, and after the key is withdrawn, the spring plate 8 can be reset through the rebound of the spring 15.
The pushing part 6 is slidably mounted on the supporting plate 3, a groove 12 is formed in one side, facing the pushing part 6, of the periphery of the shaft core 4, the inserted link 7 is mounted on the pushing part 6 and slides along with the pushing part 6, and the groove 12 is located on a sliding track at the top end of the inserted link 7. Thus, when the inserted rod 7 is inserted into the groove 12, the rotation of the shaft core 4 can be limited, so that the locking of the safety door lock is realized.
A drive plate 9 is mounted on the push part 6 below the support plate 3. The bracket 11 is arranged on the base 1, and the driving wheel 10 is rotatably arranged on the bracket 11. The spring plate 8 and the transmission plate 9 are provided with a first tooth part and a second tooth part in a distributed manner, and the transmission wheel 10 is meshed with the first tooth part and the second tooth part respectively. In this way, in the present embodiment, during the movement of the spring plate 8, the driving wheel 10 and the driving plate 9 can push the pushing block to move, so as to realize the synchronous movement of the plunger 7 and the spring plate 8.
In the embodiment, the spring plate 8 is provided with a locking position and an unlocking position in the sliding process, the spring 15 is in the locking position in the normal state, and the inserted link 7 is inserted into the groove 12; when the spring plate 8 is in the unlocking position, the spring plate 8 is positioned outside the shaft core 4, the spring 15 is compressed, the transmission plate 9 and the spring plate 8 synchronously move, and the push part 6 drives the inserted link 7 to withdraw from the groove 12; the spring plate 8 in the unlocking position abuts against a key inserted into the lock hole of the spindle 4 and matched with the lock hole.
In this way, in the safety switch cabinet provided in this embodiment, when the door is opened, the key is inserted into the lock hole 17 and pushes the spring plate 8 to compress the spring 15 until the key is completely inserted into the lock hole, the spring plate 8 is also pushed to the unlocking position, and at this time, the plunger 7 withdraws from the groove 12 along with the movement of the spring plate 8, so that the spindle 4 can rotate along with the key, thereby unlocking the door; when the door is locked, when the key is withdrawn from the lock hole, the spring plate 8 is rebounded and reset under the action of the spring 15, and drives the plunger 7 to reset and reinsert the groove 12, so that the shaft core 4 is stopped.
The safe type cubical switchboard that this embodiment provided only can insert the lockhole completely with lockhole perfect match's key to promote spring plate 8 in order to unblock axle core 4. In this way, in the present embodiment, by providing the latch plate 8 and the plunger 7, the safety door lock can be prevented from being illegally unlocked, and the safety of the switch cabinet can be improved.
In this embodiment, the spring 15 is normally inserted into the lock hole from the bottom of the shaft core 4 by the spring plate 8. Therefore, the spring plate 8 can be further pushed smoothly after the key is inserted into the lock hole, the spring plate 8 is prevented from moving and shifting, and the reliability of the safety door lock is improved.
In this embodiment, the groove 12 is a bar-shaped groove parallel to the axis of the shaft core 4, so as to ensure the reliability of locking the shaft core 4 by the plunger 7.
In this embodiment, the insert rod 7 is mounted above the support plate 3. Specifically, the support plate 3 is provided with a sliding groove 13, the pushing part 6 is composed of a pushing block and a connecting block, the pushing block is slidably mounted on the support plate 3, and the movement track of the pushing block is covered above the sliding groove 13. One end of the connecting block is connected with the transmission plate 9, and the other end of the connecting block passes through the sliding groove 13 and is connected with the pushing block. Therefore, the sliding groove 13 can guide the pushing block and limit the excessive movement of the pushing block, so that the stability of the internal structure of the safety door lock is guaranteed.
In this embodiment, the base 1 is provided with a concave limiting groove 14, and one end of the spring plate 8 away from the shaft core 4 is mounted at the bottom of the limiting groove 14 through a spring 15. The arrangement of the limit groove 14 provides a space for arranging the spring 15, which is beneficial to reducing the volume of the safety door lock; at the same time, it is also advantageous to improve the controllability of the expansion and contraction direction of the spring 15 by space restriction.
In this embodiment, in order to ensure the stability of the movement of the spring plate 8, the bottom end of the spring plate 8 is always inserted into the limiting groove 14 during the movement process, and the movement deviation is avoided.
In the present embodiment, a guide rod 16 is installed in the limiting groove 14, and the tip of the guide rod 16 is inserted into the spring plate 8 and slidably connected to the spring plate 8. The arrangement of the guide bar 16 further stabilizes the linear movement of the sprung plate 8.
In the present embodiment, the guide rods 16 are in one-to-one correspondence with the springs 15, and each spring 15 is sleeved on the corresponding guide rod 16. In this way, the spring 15 is ensured to be stretched and contracted reliably while the movement of the spring plate 8 is stabilized by the guide rod 16.
The foregoing is only a preferred embodiment of the present invention, but the scope of the present invention is not limited thereto, and any person skilled in the art should be able to apply equivalents and modifications to the technical solution and the inventive concept thereof within the scope of the present invention.
