Problems solved by technology
[0002] At present, general door locks mostly include oblique bolts, main bolts and pull bolts. The pull bolts are connected to the side bolts locked on the upper and lower door frames through connecting rods. Most of the main bolts and side bolts are locked with a key. Insert the key into the keyhole of the lock body, turn the key a few times, and the main bolt and the side bolt can be locked simultaneously through the key shifting block and the key transmission mechanism. Locking is more troublesome; second, when people are in a hurry to go out, people will just take the door and forget to lock the door with the key, resulting in the situation that the door is not locked, which is easy to cause theft of indoor items

Embodiment Construction
[0038] Below in conjunction with accompanying drawing, the present invention will be further described with specific embodiment, see figure 1 — Figure 22 :
[0039] An automatic latch, comprising a lock box 10 and a lock plate fixed on the opening of the lock box 10, the lock box 10 is provided with a lock bolt and a latch bolt 16 that can extend out of the lock hole, and the latch bolt 16 is retracted When being ejected again in the lock box 10, the bolt plate foot 161 at the rear of the bolt bolt 16 drives the bolt through the quick lock transmission mechanism to stretch out from the lock hole of the lock box 10 to lock; Mechanism can simultaneously drive dead bolt, oblique bolt 16 to slide in lock box 10 to unblank;
[0040] The above-mentioned deadbolt includes a main deadbolt 11 and left and right sliding bolts 17, 18 that drive the side deadbolts to unlock or lock.
[0041] The specific structure of the above-mentioned quick lock transmission mechanism is: the first,...

The invention belongs to the technical field of door locks, and relates to an automatic spring lock. The automatic spring lock comprises a lock box and a lock plate fixed on an opening of the lock box. A spring bolt and a slant bolt are arranged inside the lock box, wherein the spring bolt and the slant bolt can extend out of a lock hole. When the slant bolt is retracted inside the lock box and then stretched out, a slant bolt plate foot at the tail of the slant bolt drives the spring bolt through a rapid locking transmission mechanism to extend out of the lock hole of the lock box to achieve locking, rotation of a slant bolt shifting block can simultaneously drive the spring bolt and the slant bolt through a slant bolt transmission mechanism to slide towards the interior of the lock box to achieve unlocking, and rotation of a key shifting block can simultaneously drive the spring bolt and the slant bolt through a key transmission mechanism to slide towards the interior of the lock box to achieve unlocking. The automatic spring lock has the advantages that after a door is closed, the main spring bolt, a left sliding bolt and a right sliding bolt can be driven to extend out of the lock hole of the lock box to achieve automatic locking, the problem that when people go out in a hurry, the people forget to lock the door with a key is solved, and the automatic spring lock is simple in structure, high in reliability, good in safety performance and suitable for middle and high ranking automatic spring locks.
