[0027] The following will be combined with the drawings in the embodiments of the utility model to clearly and completely describe the technical solutions in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments in the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.

[0028] See also Figure 1-5 , the utility model embodiment provides a technical solution: a fully automatic door lock assembly, a fully automatic door lock assembly, comprising a mounting plate 1, a lock core 7 is mounted on the inner side of the mounting plate 1, and a cover plate 2 is mounted on the outer side of the mounting plate 1; the lock core 7 is respectively equipped with a card plate 3 and a latch hook block 4 through two groups of rivets, and the outer sides of the two groups of rivets are respectively provided with a latch hook return spring 5 and a card plate return spring 6 located in the latch hook block 4 and the card plate 3; the front end of the latch hook block 4 is provided with an end card portion 42, the card plate 3 is provided with an end card groove 32, the card plate 3 is fixedly installed with a card head 31, and the lock core 7 is also provided with a lock card 71; the top side of the latch hook block 4 is provided with a drawing groove portion 41, the cover plate 2 is provided with a guide groove 21 located outside the drawing groove portion 41, and a pull rod fixedly connected to the drawing groove portion 41 is placed in the guide groove 21;

[0029] Among them, the fully automatic door lock component, through the arrangement of various components between the mounting plate 1 and the cover plate 2, can drive the latch hook block 4 to rotate to the left by pulling the pull rod in the cover plate 2, so that the end clamping portion 42 at the bottom end is separated from the end clamping groove 32, and exerts downward pressure on the clamping plate 3 from the left oblique side to separate the clamping head 31 from 72, thereby achieving the unlocking effect. When locking is required, the pull rod is released. At this time, the latch hook return spring 5 and the clamping plate return spring 6 drive the latch hook block 4 and the clamping plate 3 to reset by their own elastic force. At the same time, the end clamping portion 42 is clamped with the end clamping groove 32, and the clamping head 31 is synchronously clamped under the lock clamp 71, limiting the lock core 7, thereby achieving the effect of automatic reset and locking, solving the problem that the existing device uses a group of torsion springs with poor reset effect and stability.

[0030] Embodiment 2: The end clamping portion 42 is arranged on the upper right side of the latch hook block 4, and the end clamping groove 32 is arranged on the lower left side of the card plate 3, and the specifications of the end clamping groove 32 and the end clamping portion 42 are adapted to each other; wherein, the arrangement of the end clamping groove 32 and the end clamping portion 42 can realize the limitation of the position of the card plate 3 through the clamping connection therebetween, and when synchronized, the clamping head 31 is clamped on the bottom of the lock card 71 to realize the locking of the position of the lock core 7 and achieve the effect of automatic locking.

[0031] The card head 31 is arranged on the right side of the card plate 3, and the lock card 71 is arranged on the left oblique side of the lock core 7, and the specifications of the lock card 71 and the card head 31 are adapted; wherein, the position setting of the card head 31 can limit the lock card 71 from the bottom side to ensure that it is in a locked state.

[0032] The lock core 7 is an oblique L-shaped lock, with a hollow portion provided in the lock core 7, and the hollow portion is filled with a buffer elastic block; wherein the setting of the hollow block of the lock core 7 can reduce its own weight, and at the same time the setting of the buffer elastic block can ensure its own stability and avoid vibration and shaking.

[0033] The left oblique upward side of the card block 3 is a smooth surface, and the outer end of the end clamping portion 42 is smooth; wherein, the smooth setting of the contact portion between the card block 3 and the latch hook block 4 facilitates pulling and subsequent clamping thereof.

[0034] The working principle and use process of the utility model are as follows: when the lock body is in the initial state, at this time, under the setting of the elastic force of the latch hook return spring 5 and the card plate return spring 6, the end card groove 32 on the bottom side of the card plate 3 is clamped under the end card portion 42 on the bottom side of the latch hook block 4. At this time, the card head 31 is clamped on the bottom side of the lock card 71 to limit the lock core 7. The lock body is in the locked state. When it is needed to be in the unlocked state, the pull rod in the cover plate 2 is pulled to drive the latch hook block 4 to move to the left. At this time, the end card portion 42 is separated from the end card groove 32. Under the influence of the card plate return spring 6, the card plate 3 is synchronously rotated to the left. At this time, the card head 31 is rotated up to the outside of the lock card 71. At this time, the lock core 7 is out of the limited state, thereby converting to the unlocked state with strong stability.

[0035] The above shows and describes the basic principles and main features of the utility model and the advantages of the utility model. For those skilled in the art, it is obvious that the utility model is not limited to the details of the above exemplary embodiments, and can be implemented in other specific forms without departing from the spirit or basic features of the utility model. Therefore, no matter from which point of view, the embodiments should be regarded as exemplary and non-restrictive. The scope of the utility model is limited by the attached claims rather than the above description, and it is intended to include all changes within the meaning and scope of the equivalent elements of the claims. Any figure mark in the claims should not be regarded as limiting the claims involved.
