Technical Field

[0001] The invention belongs to the technical field of safes, and in particular relates to an automatically opening safe. Background Art

[0002] A safe is a special container. According to its function, it is mainly divided into fireproof safes and anti-theft safes, anti-magnetic safes, fireproof and anti-magnetic safes, and fireproof and anti-theft safes, etc. Each type of safe has its own national standard. Most of the safes on the market are the first two types. According to different password working principles, anti-theft safes can be divided into mechanical safes and electronic safes. The former is characterized by relatively cheap prices and relatively reliable performance. Most of the early safes were mechanical safes. Electronic safes are electronic locks that apply electronic passwords, IC cards and other intelligent control methods to safes, and are characterized by easy use. However, during the use of existing safes, the door cannot be automatically opened effectively, resulting in the need to use a key or handle knob to open the door when using it, which is very inconvenient for the overall use process.

[0009] The following embodiments are described with reference to the attached drawings to illustrate specific embodiments of the present invention. Directional terms mentioned in the present invention, such as up, down, front, back, left, right, top, bottom, etc., are only with reference to the directions of the attached drawings. Therefore, the directional terms used are used to illustrate and understand the present invention, but are not used to limit the present invention.

[0010] like Figure 1-6 As shown, an embodiment of the present invention provides an automatically opening safe, comprising a cabinet body (1), a cabinet door, and a connection structure between the cabinet body (1) and the cabinet door, wherein a bolt structure for opening and closing with the cabinet body (1) and an electronic password lock (2) and an emergency lock (3) for controlling the opening of the bolt are installed on the cabinet door, characterized in that: the connection structure is composed of a torsion spring (12) and a door shaft (11), the torsion spring (12) buckles the cabinet body (1) on one side and buckles the door shaft (11) on the other side, when the lock position is in an open state, there is no resistance between the cabinet door and the cabinet body (1), the torsion force of the torsion spring (12) pops out the door shaft (11) to rotate, and the cabinet door slowly rotates to open, and two torsion springs (12) are provided, and a sensor switch (12) is provided between the two torsion springs. 0), a door lock device is provided on the inner side of the cabinet door, and the door lock device includes: a reduction motor (14), which is provided on the reduction motor bracket (9) on the inner side of the cabinet door; a main lock bolt pull bar lock (5), which is connected to the reduction motor (14), and the main lock bolt pull bar lock (5) has travel sensor switches (13) on the left and right sides of the pull bar. When the cabinet door is closed, the main lock bolt pull bar lock (5) pull bar touches the travel sensor switch (13) on the right side, and when the cabinet door is opened, the main lock bolt pull bar lock (5) pull bar touches the travel sensor switch (13) on the left side; a lock bolt, which is connected to the main lock bolt pull bar lock (5) and extends to the side of the cabinet door; a circuit main board (8), which is fixedly installed above the reduction motor (14) on the inner side of the cabinet door. The reduction motor (14), the circuit main board (8), the electronic password lock (2), the sensor switch (10), and the travel sensor switch (13) are electrically connected, such as Figure 6 The lock bolt comprises an upper lock bolt (6), a lower lock bolt (7) and a side lock bolt (15). When the cabinet door is opened, the reduction motor (14) drives the lock bolt to retract through a transmission mechanism, so that the lock bolt withdraws from the lock position of the cabinet; when the cabinet door is closed, the reduction motor (14) drives the lock bolt to extend through a transmission mechanism, so that the lock bolt extends into the lock position of the cabinet. The emergency lock (3) is connected to an emergency lock dial block (4). The emergency lock dial block (4) is arranged on the inner side of the cabinet door and is locked to the reduction motor (14).

[0011] Working principle: When the door is open Figure 4As shown, the cabinet body (1) opens the cabinet door. First, after the correct password is entered on the electronic password lock (2), the reduction motor (14) is powered to rotate, and the main lock bolt pull bar lock (5) pull bar slides backward. During the sliding process of the main lock bolt pull bar lock (5), the upper lock bolt (6), the lower lock bolt (7) and the side lock bolt (15) are simultaneously retracted and leave the lock position. The main lock bolt pull bar lock (5) pull bar touches the travel sensor switch (13) and the reduction motor stops operating. The lock bolt is in the open state. The torsion force of the torsion spring (12) pops out the door shaft (11) to rotate, and the cabinet door slowly rotates to open.

[0012] The cabinet door is closed as usual. Figure 3 As shown, the cabinet body (1) closes the cabinet door, and the cabinet door is pushed to the closed state with the cabinet body (1), the sensor switch (10) touches the cabinet body (1), the reduction motor (14) is powered to rotate, and the main lock bolt pull bar lock (5) pull bar slides forward. During the sliding process of the main lock bolt pull bar lock (5), the upper lock bolt (6), the lower lock bolt (7) and the side lock bolt (15) are simultaneously extended to the locking position, and the main lock bolt pull bar lock (5) pull bar touches the travel sensor switch (13) and the reduction motor stops operating, and the lock bolt is in the closed state.

[0013] To open the cabinet door in an emergency situation of power failure, the emergency opening function should be activated. The emergency key is inserted into the emergency lock (3) and the emergency dial is turned clockwise to operate accordingly. The emergency dial (4) drives the reduction motor (14) to slide the lock backward. The reduction motor (14) drives the main lock bolt pull bar lock (5) to slide backward. During the sliding process of the main lock bolt pull bar lock (5), the upper lock bolt (6), the lower lock bolt (7) and the side lock bolt (15) are driven to retract and leave the lock position at the same time. There is no resistance between the cabinet door and the cabinet body (1). The torsion force of the torsion spring (15) causes the door shaft (11) to rotate. The cabinet door slowly rotates to open and the cabinet door automatically pops up and opens. In case of emergency door closing, the cabinet door is pushed to the closed state, and the emergency key is rotated counterclockwise in the emergency lock (3) to drive the emergency dial block (4) until the reduction motor (14) slides forward, and the reduction motor (14) drives the main lock bolt pull bar lock (5) to slide forward. During the sliding process of the main lock bolt pull bar lock (5), the upper lock bolt (6), the lower lock bolt (7) and the side lock bolt (15) are simultaneously extended into the locking position, and the cabinet body (1) is locked, and the emergency key is pulled out.
