[0125] In order to make the purpose, technical solution and advantages of the present application clearer, the technical solution of the present application will be clearly and completely described below in combination with the specific embodiments of the present application and the corresponding drawings. Obviously, the described embodiments are only part of the embodiments of the present application, not all of the embodiments. Based on the embodiments in the present application, all other embodiments obtained by ordinary technicians in this field without making creative work are within the scope of protection of the present application.

[0126] Please refer to Figure 1 The present application discloses a safety door, the safety door 100 comprising:

[0127] Door panel 11;

[0128] A door panel lock tongue assembly 12 disposed on the door panel 11 and moving relative to the door panel 11, and used to lock or unlock the door panel 11;

[0129] A limiting mechanism 13 disposed on the door panel 11 and connected to or separated from the door panel lock tongue assembly 12, for limiting or releasing the movement of the door panel lock tongue assembly 12;

[0130] The relocking mechanism 14 is disposed on the door panel 11 and moves relative to the door panel 11 , and is used for performing secondary limiting on the door panel lock tongue assembly 12 when the limiting mechanism 13 is damaged.

[0131] It is understandable that the door panel 11 serves as a shield for the entrance and exit of the passage. When the door panel 11 can rotate freely, the passage can pass freely. When the rotation of the door panel 11 is restricted, the passage cannot pass, thereby protecting one end of the passage.

[0132] The door panel lock tongue assembly 12 moves relative to the door panel 11, and is used to lock or unlock the door panel 11, that is, to limit or allow the door panel 11 to rotate. Specifically, the door panel lock tongue assembly 12 moves relative to the door panel, and has a first mating state and a second mating state. In the first mating state, at least a portion of the door panel lock tongue assembly 12 extends relative to the door panel 11, limiting the rotation of the door panel 11. In the second mating state, at least a portion of the door panel lock tongue assembly 12 that extends relative to the door panel 11 retracts, allowing the door panel 11 to rotate. The setting of the door panel lock tongue assembly 12 can be understood as the most basic protection measure for the safety door 100.

[0133] Please refer to Figure 2 In a specific embodiment provided in the present application, in order to support the door panel lock tongue assembly 12 to lock or unlock the door panel 11, the door panel lock tongue assembly 12 includes:

[0134] Door panel lock tongue 121;

[0135] A bolt plate 122 is disposed in the door panel 11 and is linked to the door panel lock tongue 121 .

[0136] Specifically, the bolt plate 122 is provided with a sliding groove, and can slide relative to the door panel 11, so as to realize a first matching state and a second matching state between the door panel lock tongue assembly 12 and the door panel 11. In the first matching state, the bolt plate 122 slides along a first direction, driving at least a portion of the door panel lock tongue 121 to extend relative to the door panel 11, thereby limiting the rotation of the door panel 11. In the second matching state, the bolt plate 122 slides along a second direction different from the first direction, and at least a portion of the door panel lock tongue 121 extending relative to the door panel 11 retracts, thereby allowing the door panel 11 to rotate. The setting of the door panel lock tongue assembly 12 can be understood as the most basic protection measure for the safety door 100.

[0137] Furthermore, in a specific embodiment provided in the present application, in order to support the door panel lock tongue assembly 12 to lock or unlock the door panel 11, the safety door 100 further includes:

[0138] A rack 15 linked to the door panel bolt assembly;

[0139] A rotating wheel 16 mounted on the door panel;

[0140] A gear rotates integrally with the rotating wheel and meshes with the rack.

[0141] It can be understood that when the rotating wheel 16 starts to rotate in the first circumferential direction due to an external force, the gear rotating integrally with the rotating wheel will drive the rack 15 to move in the first direction. When the rack 15 moves in the first direction, the door panel lock tongue assembly is driven to move in the first direction, and at least a portion of the door panel lock tongue assembly 12 extends relative to the door panel 11, restricting the door panel 11 from rotating, thereby achieving a first matching state between the door panel lock tongue assembly 12 and the door panel 11.

[0142] When the rotating wheel 16 starts to rotate in a second circumferential direction opposite to the first circumferential direction due to an external force, the gear rotating integrally with the rotating wheel will drive the rack 15 to move in a second direction opposite to the first direction. When the rack 15 moves in the second direction, the door panel lock tongue assembly is driven to move in the second direction, and at least a portion of the door panel lock tongue assembly 12 extending relative to the door panel 11 is retracted, allowing the door panel 11 to rotate, thereby achieving a second matching state between the door panel lock tongue assembly 12 and the door panel 11.

[0143] In other words, whether the current door panel 11 can rotate is controlled by the operator who provides external force.

[0144] Furthermore, the safety of the safety door 100 can be further improved by conducting an authority review on the operator's control.

[0145] Specifically, the safety door 100 is provided with a limiting mechanism 13. The limiting mechanism 13 is arranged on the door panel 11, and is matched or separated from the door panel lock tongue assembly 12, and is used to limit or release the movement of the door panel lock tongue assembly 12, as a basis for proposing an authority review of the operator's control. The limiting mechanism 13 is linked with the password lock, and the operator's control can be reviewed for authority. For example, when the password lock is locked, the limiting mechanism 13 is matched with the door panel lock tongue assembly 12 to limit the movement of the door panel lock tongue assembly 12. When the movement of the door panel lock tongue assembly 12 is restricted, the rotation of the door panel 11 will also be restricted.

[0146] When the password lock is unlocked, the limiting mechanism 13 is separated from the door panel lock tongue assembly 12, and the movement restriction of the door panel lock tongue assembly 12 is released. The door panel lock tongue assembly 12 allows the door panel 11 to rotate.

[0147] Please refer to Figure 3 In order to support the password lock to review the control authority of the operator, in a specific implementation mode provided in the present application, the limit mechanism 13 includes:

[0148] A first blocking member 131, a second blocking member 132 and a third blocking member 133 which are disposed on the door panel 11 and move relative to the door panel 11 and are separate from each other;

[0149] A first stopper 134, a second stopper 135 and a third stopper 136 are disposed on the door panel 11 and correspond to the first stopper 131, the second stopper 132 and the third stopper 133 respectively;

[0150] A first connecting rod 137 connected to the first limiting member 134 and the second limiting member 135;

[0151] A second connecting rod 138 connected to the third limiting member 136 and the first connecting rod 137;

[0152] The second connecting rod 138 is matched with the door panel locking tongue assembly 12 .

[0153] It should be noted that the first link 137 in the limiting mechanism 13 connects the first limiting member 134 and the second limiting member 135; the second link 138 connects the third limiting member 136 and the first link 137, so that a three-position two-way control method can be implemented. That is, when any two blocking members in the limiting mechanism 13 are separated from the corresponding two limiting members, the first link 137 or the second link 138 can complete the entire retraction stroke, allowing the door panel bolt assembly 12 to complete the entire retraction stroke, and allowing the door panel 11 to rotate.

[0154] Specifically, the limiting mechanism 13 has three states. In the first state, the first blocking member 131, the second blocking member 132 and the third blocking member 133 are matched with the corresponding first limiting member 134, the second limiting member 135 and the third limiting member 136 to limit the corresponding first limiting member 134, the second limiting member 135 and the third limiting member 136 from retreating, limiting the movement of the first connecting rod 137 and the second connecting rod 138, limiting the movement of the door panel lock tongue assembly 12, and limiting the rotation of the door panel 11.

[0155] When the limiting mechanism is in the second state, two of the first blocking members 131, the second blocking members 132 and the third blocking members 133 are matched with the corresponding two of the first limiting members 134, the second limiting members 135 and the third limiting members 136, allowing the corresponding two of the first limiting members 134, the second limiting members 135 and the third limiting members 136 to retreat, allowing the first connecting rod 137 or the second connecting rod 138 to complete a partial retreat stroke, allowing the door panel lock tongue assembly 12 to complete a partial retreat stroke, and limiting the rotation of the door panel 11.

[0156] When the limiting mechanism is in the third state, two of the first blocking members 131, the second blocking members 132 and the third blocking members 133 are separated from the corresponding two of the first limiting members 134, the second limiting members 135 and the third limiting members 136, allowing the corresponding two of the first limiting members 134, the second limiting members 135 and the third limiting members 136 to retreat, allowing the first connecting rod 137 or the second connecting rod 138 to complete the entire retreat stroke, allowing the door panel lock tongue assembly 12 to complete the entire retreat stroke, and allowing the door panel 11 to rotate.

[0157] Further, in a specific implementation provided in the present application, the safety door 100 further includes a first password lock, a second password lock and a third password lock;

[0158] The first blocking member 131 is disposed on the first password lock;

[0159] The second blocking member 132 is disposed on the second password lock;

[0160] The third blocking member 133 is disposed on the third combination lock.

[0161] Specifically, the first password lock controls the extension or retraction of the first blocking member 131, and controls the connection or separation of the first blocking member 131 and the first limiting member 134. The second password lock controls the extension or retraction of the second blocking member 132, and controls the connection or separation of the second blocking member 132 and the second limiting member 135. The third password lock controls the extension or retraction of the third blocking member 133, and controls the connection or separation of the third blocking member 133 and the third limiting member 136.

[0162] It is understandable that the first password lock, the second password lock and the third password lock are provided with passwords for checking the control authority of the operator. Since the limit mechanism 13 can realize the three-position two-way control method, when the passwords of at least two of the first password lock, the second password lock and the third password lock are correct, the control authority of the operator can unlock the limit mechanism 13. Furthermore, the operator can control the door panel lock tongue assembly 12 to lock or unlock the door panel 11.

[0163] The password lock and the limit mechanism 13 can realize the authority review of the operator, and further improve the safety performance of the safety door.

[0164] Considering that the limiting mechanism 13 may be damaged when the door panel 11 is locked, the safety door 100 is further provided with a relocking mechanism 14. The relocking mechanism 14 is provided on the door panel and moves relative to the door panel, and is used to perform a secondary limit on the door panel lock tongue assembly 12 when the limiting mechanism is damaged.

[0165] Please refer to Figure 4 and Figure 5 In a specific implementation provided in the present application, the relocking mechanism 14 includes:

[0166] A protection member 141 for protecting the limiting mechanism 13;

[0167] A relocking bolt assembly 142 restrained by a protective member 141;

[0168] A relock bolt positioning portion 143 disposed on the door panel 11 and coupled to the relock bolt assembly 142;

[0169] One end of the relocking tongue assembly 142 is connected to the door panel locking tongue assembly 12 , and the other end of the relocking tongue assembly 142 is selectively matched with the relocking tongue positioning portion 143 .

[0170] Specifically, the protective member 141 is a baffle that covers the limiting mechanism 13, that is, the protective member 141 is arranged between the limiting mechanism 13 and the door panel 11. The relocking bolt assembly 142 includes an elastic member 1421 and a relocking bolt 1422 driven by the elastic member, and the baffle restricts the elastic member 1421 from driving the relocking bolt 1422.

[0171] It should be noted that the elastic member 1421 is sleeved on the relocking tongue 1422 and is restricted and compressed by the baffle through the connecting member. When the baffle is destroyed, the elastic member 1421 loses its restriction. When the elastic member 1421 loses its restriction, the elastic member 1421 exerts its compressed elastic force on the relocking tongue 1422, driving the relocking tongue 1422 to extend relative to the relocking tongue positioning portion 143.

[0172] In a specific embodiment provided in the present application, the baffle can be made of a high-hardness material, so that before destroying the limiting mechanism 13, the high-hardness baffle must be destroyed first, which increases the difficulty of destroying the limiting mechanism 13 and further improves the safety performance of the safety door 100.

[0173] In another specific embodiment provided by the present application, the baffle can be made of a shattering material, such as glass, tempered glass, etc. Thus, before destroying the limiting mechanism 13, the baffle must be destroyed first, so that the baffle is broken and ineffective. When the baffle is destroyed, the elastic member 1421 loses its restriction.

[0174] Since one end of the relock bolt assembly 142 is connected to the door panel bolt assembly 12, and the other end of the relock bolt assembly 142 is selectively matched with the relock bolt positioning portion 143, and the relock bolt positioning portion 143 is arranged on the door panel 11, the relock bolt assembly 142 has two installation positions.

[0175] The first installation position is: the relocking tongue assembly 142 is installed in the relocking tongue positioning part 143, and the relocking tongue positioning part 143 is installed on the side of the blocking member of the limiting mechanism 13. Specifically, the relocking tongue positioning part 143 is provided with three groups, and the relocking tongue assembly 142 is also provided with three groups corresponding to the relocking tongue positioning part 143, which are respectively installed on the first blocking member 131, the second blocking member 132 and the third blocking member 133. When the baffle is destroyed, the elastic member 1421 loses its restriction. The elastic member 1421 applies the compressed elastic force to the relocking tongue 1422, driving the relocking tongue 1422 to extend. At least two of the corresponding first limiting member 134, the second limiting member 135 and the third limiting member 136 are restricted to retreat, the first connecting rod 137 and the second connecting rod 138 are restricted to move, the door panel lock tongue assembly 12 is restricted to move, and the door panel 11 is restricted to rotate. Thus, the secondary position limitation of the door panel lock tongue assembly 12 is achieved, the anti-theft function of the safety door 100 is increased, and the safety performance is further improved.

[0176] The second installation position is: the relock bolt assembly 142 is installed in the relock bolt positioning portion 143 , and the relock bolt positioning portion 143 is installed on one side of the bolt plate 122 .

[0177] Specifically, one end of the relocking tongue 1422 is connected to or separated from the bolt plate 122, and is used to limit or release the movement of the door panel bolt assembly 12. When the baffle is destroyed, the elastic member 1421 loses its restriction. The elastic member 1421 applies the compressed elastic force to the relocking tongue 1422, driving the relocking tongue 1422 to extend relative to the relocking tongue positioning portion 143. The extended portion of the relocking tongue 1422 is connected to the bolt plate 122, limiting the movement of the bolt plate 122 relative to the door panel 11, limiting the movement of the door panel bolt 121 linked to the bolt plate 122, and limiting the rotation of the door panel 11. Thus, the secondary position limitation of the door panel bolt assembly 12 is achieved, the anti-theft function of the safety door 100 is increased, and the safety performance is further improved.

[0178] In the specific implementation process of the safety door 100, the basic protection function of the safety door 100 is realized by setting the door panel lock tongue assembly 12; the first locking of the safety door 100 is realized by setting the limit mechanism 13; the review of the operator's control authority is realized by setting the password lock; and the second locking of the safety door 100 is realized by setting the relocking mechanism 14. The anti-theft function of the safety door 100 is increased, and the safety performance of the safety door 100 is improved.

[0179] The present application also discloses a safe storage device, the safe storage device comprising:

[0180] Cavity;

[0181] A door panel matched with the cavity is used to form a storage space with the cavity;

[0182] A door panel lock tongue assembly disposed on the door panel and moving relative to the door panel, used to lock or unlock the door panel;

[0183] A limiting mechanism disposed on the door panel and connected to or separated from the door panel lock tongue assembly, used to limit or release the movement of the door panel lock tongue assembly;

[0184] A relocking mechanism is arranged on the door panel and moves relative to the door panel, and is used for performing secondary limiting on the door panel lock tongue assembly when the limiting mechanism is damaged.

[0185] It is understandable that the door panel serves as a shield for the entrance and exit of the safety storage device. When the door panel can rotate freely, the safety storage device can be opened freely. When the rotation of the door panel is restricted, the safety storage device cannot be opened, thereby protecting the safety storage device.

[0186] The door panel lock tongue assembly moves relative to the door panel and is used to lock or unlock the door panel, that is, to limit or allow the door panel to rotate. Specifically, the door panel lock tongue assembly moves relative to the door panel and has a first mating state and a second mating state. In the first mating state, at least a portion of the door panel lock tongue assembly extends relative to the door panel to limit the door panel from rotating. In the second mating state, at least a portion of the door panel lock tongue assembly that extends relative to the door panel retracts to allow the door panel to rotate. The setting of the door panel lock tongue assembly can be understood as the most basic protection measure for the safety storage device.

[0187] It should be noted that, in a specific embodiment provided in the present application, in order to support the door panel lock tongue assembly to lock or unlock the door panel, the door panel lock tongue assembly includes:

[0188] Door panel lock tongue;

[0189] A bolt plate is arranged in the door panel and is linked to the door panel lock tongue.

[0190] Specifically, the bolt plate is provided with a sliding groove, which can slide relative to the door panel, so as to realize a first matching state and a second matching state between the door panel lock tongue assembly and the door panel. In the first matching state, the bolt plate slides along a first direction, driving at least a portion of the door panel lock tongue to extend relative to the door panel, thereby limiting the rotation of the door panel. In the second matching state, the bolt plate slides along a second direction different from the first direction, and at least a portion of the door panel lock tongue extending relative to the door panel retracts, thereby allowing the door panel to rotate. The setting of the door panel lock tongue assembly can be understood as the most basic protection measure for the safety storage device.

[0191] Furthermore, in a specific embodiment provided in the present application, in order to support the door panel lock tongue assembly to lock or unlock the door panel, the safety storage device further includes:

[0192] A rack linked to the door panel bolt assembly;

[0193] A rotating wheel mounted on the door panel;

[0194] A gear rotates integrally with the rotating wheel and meshes with the rack.

[0195] It can be understood that when the rotating wheel starts to rotate in the first circumferential direction due to an external force, the gear rotating integrally with the rotating wheel will drive the rack to move in the first direction. When the rack moves in the first direction, the door panel lock tongue assembly is driven to move in the first direction, and at least a portion of the door panel lock tongue assembly extends relative to the door panel to restrict the rotation of the door panel, thereby achieving a first matching state between the door panel lock tongue assembly and the door panel.

[0196] When the rotating wheel starts to rotate in a second circumferential direction opposite to the first circumferential direction due to an external force, the gear rotating integrally with the rotating wheel will drive the rack to move in a second direction opposite to the first direction. When the rack moves in the second direction, the door panel lock tongue assembly is driven to move in the second direction, and at least a portion of the door panel lock tongue assembly extending relative to the door panel retracts, allowing the door panel to rotate, thereby achieving a second matching state between the door panel lock tongue assembly and the door panel.

[0197] In other words, whether the door panel can be rotated is currently controlled by the operator who provides external force.

[0198] Furthermore, proposing an authority review for the operator's control can further improve the security of the safety storage device.

[0199] Specifically, the safety storage device is provided with a limiting mechanism. The limiting mechanism is arranged on the door panel, and is matched with or separated from the door panel lock tongue assembly, and is used to limit or release the restriction on the movement of the door panel lock tongue assembly, which serves as a basis for the authority review of the operator's control. The limiting mechanism is linked with the password lock, and the authority review of the operator's control can be performed. For example, when the password lock is locked, the limiting mechanism is matched with the door panel lock tongue assembly to limit the movement of the door panel lock tongue assembly. When the movement of the door panel lock tongue assembly is restricted, the rotation of the door panel will also be restricted.

[0200] When the password lock is unlocked, the limiting mechanism is separated from the door panel lock tongue assembly, and the movement restriction of the door panel lock tongue assembly is released. The door panel lock tongue assembly allows the door panel to rotate.

[0201] It should be emphasized that in order to support the password lock to review the control authority of the operator, in a specific implementation mode provided in this application, the limit mechanism includes:

[0202] A first blocking member, a second blocking member and a third blocking member which are arranged on the door panel and move relative to the door panel and are separate from each other;

[0203] a first stopper, a second stopper and a third stopper, which are arranged on the door panel and correspond to the first stopper, the second stopper and the third stopper respectively;

[0204] A first connecting rod connected to the first limiting member and the second limiting member;

[0205] A second connecting rod connected to the third limiting member and the first connecting rod;

[0206] The second connecting rod is matched with the door panel lock tongue assembly.

[0207] It should be noted that the first link in the limit mechanism connects the first limit piece and the second limit piece; the second link connects the third limit piece and the first link, so that a three-position two-way control method can be realized. That is, if any two blocking members in the limit mechanism are separated from the corresponding two limit pieces, the first link or the second link can complete the entire retraction stroke, allowing the door panel lock tongue assembly to complete the entire retraction stroke, and allowing the door panel to rotate.

[0208] Specifically, the limiting mechanism has three states. In the first state, the first blocking member, the second blocking member and the third blocking member are matched with the corresponding first limiting member, the second limiting member and the third limiting member to limit the corresponding first limiting member, the second limiting member and the third limiting member from retreating, limiting the movement of the first connecting rod and the second connecting rod, limiting the movement of the door panel lock tongue assembly, and limiting the rotation of the door panel.

[0209] When the limiting mechanism is in the second state, two of the first blocking member, the second blocking member and the third blocking member are matched with the corresponding two of the first limiting member, the second limiting member and the third limiting member, allowing the corresponding two of the first limiting member, the second limiting member and the third limiting member to retract, allowing the first connecting rod or the second connecting rod to complete a partial retraction stroke, allowing the door panel lock tongue assembly to complete a partial retraction stroke, and limiting the rotation of the door panel.

[0210] When the limiting mechanism is in the third state, two of the first blocking member, the second blocking member and the third blocking member are separated from the corresponding two of the first limiting member, the second limiting member and the third limiting member, allowing the corresponding two of the first limiting member, the second limiting member and the third limiting member to retract, allowing the first connecting rod or the second connecting rod to complete the entire retraction stroke, allowing the door panel lock tongue assembly to complete the entire retraction stroke, and allowing the door panel to rotate.

[0211] Further, in a specific embodiment provided in the present application, the safety storage device further includes a first password lock, a second password lock and a third password lock;

[0212] The first blocking member is disposed on the first password lock;

[0213] The second blocking member is disposed on the second password lock;

[0214] The third blocking member is arranged on the third password lock.

[0215] Specifically, the first password lock controls the extension or retraction of the first blocking member, and controls the connection or separation of the first blocking member and the first limiting member. The second password lock controls the extension or retraction of the second blocking member, and controls the connection or separation of the second blocking member and the second limiting member. The third password lock controls the extension or retraction of the third blocking member, and controls the connection or separation of the third blocking member and the third limiting member.

[0216] It is understandable that the first password lock, the second password lock and the third password lock are provided with passwords for checking the control authority of the operator. Since the limit mechanism can realize the three-position two-way control method, when the passwords of at least two of the first password lock, the second password lock and the third password lock are correct, the control authority of the operator can unlock the limit mechanism. Furthermore, the operator can control the door panel lock tongue assembly to lock or unlock the door panel.

[0217] The password lock and the limit mechanism realize the authority review of the operator, and further improve the safety performance of the safety storage device.

[0218] Considering that the limiting mechanism may be damaged when the door panel is locked, the safety storage device is also provided with a relocking mechanism. The relocking mechanism is provided on the door panel and moves relative to the door panel, and is used to perform a secondary limit on the door panel lock tongue assembly when the limiting mechanism is damaged.

[0219] It should be particularly emphasized that, in a specific implementation provided in the present application, the relocking mechanism includes:

[0220] A protective member for protecting the limiting mechanism;

[0221] A relocking bolt assembly restrained by a guard;

[0222] A relock bolt positioning portion provided on the door panel and matched with the relock bolt assembly;

[0223] One end of the relocking tongue assembly is connected to the door panel locking tongue assembly, and the other end of the relocking tongue assembly is selectively matched with the relocking tongue positioning portion.

[0224] Specifically, the protective member is a baffle that covers the limiting mechanism, that is, the protective member is arranged between the limiting mechanism and the door panel. The relocking bolt assembly includes an elastic member and a relocking bolt driven by the elastic member, and the baffle restricts the elastic member from driving the relocking bolt.

[0225] It should be noted that the elastic member is sleeved on the relocking tongue and is restricted and compressed by the baffle through the connecting member. When the baffle is destroyed, the elastic member loses its restriction. When the elastic member loses its restriction, the elastic member exerts its compressed elastic force on the relocking tongue, driving the relocking tongue to extend relative to the relocking tongue positioning portion.

[0226] In a specific embodiment provided in the present application, the baffle may be made of a high-hardness material, so that before destroying the limiting mechanism, the high-hardness baffle must be destroyed first, thereby increasing the difficulty of destroying the limiting mechanism and further improving the safety performance of the safety storage device.

[0227] In another specific embodiment provided by the present application, the baffle can be made of a shattering material, such as glass, tempered glass, etc. Thus, before destroying the limiting mechanism, the baffle must be destroyed first, so that the baffle is broken and ineffective. When the baffle is destroyed, the elastic member loses its restriction.

[0228] Since one end of the relocking tongue assembly is connected to the door panel locking tongue assembly, and the other end of the relocking tongue assembly is selectively matched with the relocking tongue positioning part, and the relocking tongue positioning part is arranged on the door panel, the relocking tongue assembly has two installation positions.

[0229] The first installation position is: the relock tongue assembly is installed in the relock tongue positioning part, and the relock tongue positioning part is installed on the side of the blocking member of the limiting mechanism. Specifically, the relock tongue positioning part is provided with three groups, and the relock tongue assembly is also provided with three groups corresponding to the relock tongue positioning part, which are respectively installed on the first blocking member, the second blocking member and the third blocking member. When the baffle is destroyed, the elastic member loses its restriction. The elastic member applies the compressed elastic force to the relock tongue, driving the relock tongue to extend. Limit at least two of the corresponding first limiting member, the second limiting member and the third limiting member to retract, limit the movement of the first connecting rod and the second connecting rod, limit the movement of the door panel lock tongue assembly, and limit the rotation of the door panel. Thereby realizing the secondary limitation of the door panel lock tongue assembly, increasing the anti-theft function of the safety storage device, and further improving the safety performance.

[0230] The second installation position is: the relock bolt assembly is installed in the relock bolt positioning portion, and the relock bolt positioning portion is installed on one side of the bolt plate.

[0231] Specifically, one end of the relocking tongue is connected to or separated from the bolt plate, which is used to limit or release the restriction on the movement of the door panel bolt assembly. When the baffle is destroyed, the elastic member loses its restriction. The elastic member applies the compressed elastic force to the relocking tongue, driving the relocking tongue to extend relative to the relocking tongue positioning portion. The extended portion of the relocking tongue is connected to the bolt plate, which limits the movement of the bolt plate relative to the door panel, limits the movement of the door panel bolt that is linked to the bolt plate, and limits the rotation of the door panel. Thereby, the secondary position limitation of the door panel bolt assembly is achieved, the anti-theft function of the safety storage device is increased, and the safety performance is further improved.

[0232] In the specific implementation process of the safety storage device, the basic protection function of the safety storage device is realized by setting the door panel lock tongue assembly; the first locking of the safety storage device is realized by setting the limit mechanism; the review of the operator's control authority is realized by setting the password lock; and the second locking of the safety storage device is realized by setting the relocking mechanism. The anti-theft function of the safety storage device is increased, and the safety performance of the safety storage device is improved.

[0233] It should be noted that the terms "include", "comprises" or any other variations thereof are intended to cover non-exclusive inclusion, so that a process, method, commodity or device including a series of elements includes not only those elements, but also other elements not explicitly listed, or also includes elements inherent to such process, method, commodity or device. In the absence of further restrictions, an element defined by the phrase "comprises a ..." does not exclude the existence of other identical elements in the process, method, commodity or device including the element.

Memory may include non-permanent memory in a computer-readable medium, random access memory (RAM) and / or non-volatile memory in the form of read-only memory (ROM) or flash RAM. Memory is an example of a computer-readable medium. Computer-readable media include permanent and non-permanent, removable and non-removable media that can be implemented by any method or technology to store information. Information can be computer-readable instructions, data structures, modules of programs, or other data.
