Description

Intelligent self-spring lock body

Technical Field

The utility model relates to the field of intelligent door locks, in particular to an intelligent self-ejection type lock body.

Background

The current popularity of intelligent door locks is high, and the requirements of people on the performance of lock bodies are gradually increased.

Intelligent door locks generally include two or more locking bolts that extend from the lock body and snap into a slot in the door frame to prevent the door from being opened. Most of the door lock structures in the market at present mainly depend on manual retraction of a user when the lock tongue is retracted, so that the user experience is poor. Therefore, the rotation of the lock cylinder is directly controlled by the motor, so that the lock tongue is retracted in a mode of screwing the key by a hand, the automatic lock tongue retracting mode can facilitate the door closing operation of a user, and the user experience is improved.

However, the lock core is directly driven to rotate by the motor, so that the power of the motor is higher, the torque force is larger, the corresponding volume is larger, on one hand, the energy consumption is increased, and on the other hand, the overall design requirement on the door lock is higher due to the large occupied space.

Referring to FIGS. 1 and 2, an intelligent self-locking lock comprises

The shell 1 is arranged in a door frame, two tongue outlet holes 11 are formed in the left side face of the shell, a first tongue 2111 and a second tongue 2211 which are described below extend, a motor box is arranged at the top of the shell 1, a vertically arranged motor 4 is arranged in the motor box, the output end of the motor 4 is connected with a screw 5, the screw 5 is meshed with each other through a plurality of gears 7, power is transmitted to a rack 6, and accordingly the rack 6 is driven to slide up and down. The lower end of the rack 6 is connected with the sliding piece 3, and the rack 6 drives the sliding piece 3 to slide up and down in the shell 1.

A latch bolt assembly is further arranged in the shell 1, and at least two latch bolt outlet holes 11 are formed in the left side of the latch bolt assembly shell 1 and are respectively used for enabling the first latch bolt 2111 and the second latch bolt 2211 to extend out. An insertion groove is formed in the left side of the door frame, the insertion groove is arranged at the position where the first lock tongue 2111 extends out, and the first lock tongue 2111 extends into the insertion groove to lock the door. The first latch 2111 is a shoe tongue, and when the door is closed, one side of the first latch 2111 which is inclined is contacted with the door frame, and after the first latch 2111 is inserted into the insertion groove, the other side is parallel to the side wall of the insertion groove and is abutted with the side wall of the insertion groove, so that the door is locked.

First spring bolt 2111 and second spring bolt 2211 all install on spring bolt fixed plate 2, set up two mounting panels on the spring bolt fixed plate 2 an organic whole, be first mounting panel 21 and second mounting panel 22 respectively, first mounting panel 21 is located second mounting panel 22 top, all offer the through-hole in two mounting panels, sliding insertion first slide bar 211 and second slide bar 221 respectively, first spring bolt 2111 of first slide bar 211 left side fixed connection, second slide bar 221 left side fixed connection lock tongue installed part 2212, set up vertical pivot in the spring bolt head installed part 2212, rotate on it and connect lock tongue 2213. The tongue head 2213 is a triangle tongue, and because of its rotatable arrangement, it rotates when contacting the door frame, which corresponds to the side becoming a oblique tongue, reducing the sound of collision. The first sliding rod 211 and the second sliding rod 221 are respectively sleeved with a first spring 23 and a second spring 24, the first spring 23 is positioned between the first lock tongue 2111 and the first mounting plate 21, the second spring 24 is positioned between the second lock tongue 2211 and the second mounting plate 22, meanwhile, a third spring 25 is arranged between the second mounting plate 22 and the right side of the shell 1, and the third spring is also sleeved on the second sliding rod 221.

Because no insertion groove is arranged on the door frame at the position of the second lock tongue 2211, the second mounting plate 22 is abutted by the L-shaped abutting part 31 on the sliding part 3 when the door is closed, so that the second spring 24 is compressed, the motor 4 drives the sliding part 3 to slide downwards when the door is opened, the first mounting plate 21 and the second mounting plate 22 respectively enter the two accommodating grooves 32, the second spring 24 releases stored elastic potential energy to drive the lock tongue fixing plate 2 to integrally move rightwards, the first lock tongue 2111 is also driven to move rightwards to finish the door opening, at the moment, the second lock tongue 2111 is still abutted on the door frame, and the third spring 25 on the right side is in a compressed state. When the door is completely opened, the left side of the second lock tongue 2211 has a displacement space, and the third spring 25 is reset, so that the second lock tongue 2211 pops out, and drives the lock tongue fixing plate 2, so that the first lock tongue 2111 pops out correspondingly. When the door is closed, the slider 3 slides upward, the abutting portion 31 is abutted against the first mounting plate 21 and the second mounting plate 22 again, the first lock tongue 2111 is contacted with the door frame, the first spring 23 is compressed, and when the first lock tongue 2111 enters the insertion groove, the first spring 23 is reset, and the first lock tongue 2111 is ejected.

The motor 4 only plays a role in driving the sliding part 3 to lift, and compared with the mode of directly driving the lock tongue to translate by overcoming the resistance of the spring, the energy consumption is greatly reduced, so that the motor 4 can be of a smaller model, and the occupied space is reduced.

The foregoing has shown and described the basic principles and main features of the present utility model and the advantages of the present utility model. It will be understood by those skilled in the art that the present utility model is not limited to the embodiments described above, and that the above embodiments and descriptions are merely illustrative of the principles of the present utility model, and various changes and modifications may be made without departing from the spirit and scope of the utility model, which is defined in the appended claims. The scope of the utility model is defined by the appended claims and equivalents thereof.
