Description

Technical Field

[0001] The invention belongs to the technical field of precious metal equipment, and more specifically, relates to a safe. Background Art

[0002] Safes, also known as safe deposit boxes, are a common device used by people in daily life to protect the safety of property, information, and personal belongings. They are highly practical and popular. Among the many safes, safes used to temporarily store precious metals such as gold and platinum are more common. For example, banks need to use safes to store and transport precious metals.

[0003] In recent years, a self-service gold exchange terminal called smart gold exchange machine has appeared on the market. The smart gold exchange machine can automatically recycle gold and other precious metals. Generally, after the gold exchange machine recycles the gold, it needs to be transferred to a safe for temporary storage and transported to a bank for storage and sealing. The existing safes control the opening and closing of the door by setting a mechanical lock in the box. When transferring the precious metals in the gold exchange machine to the safe, the operator needs to manually open the door of the safe and then align the input port of the safe with the output port of the gold exchange machine. After the precious metals are transferred, the door is manually closed. The safe cannot work autonomously with the gold exchange machine to complete the autonomous transfer of precious metals. The precious metal transfer process is cumbersome and the transfer efficiency is difficult to effectively improve. Summary of the invention

[0004] The purpose of the embodiments of the present invention is to provide a safe to solve the technical problem that the safe in the prior art needs to be opened and closed manually, resulting in the inability to work autonomously with the gold exchange machine to complete the autonomous transfer of precious metals.

[0047] In addition, the terms "first" and "second" are used for descriptive purposes only and should not be understood as indicating or implying relative importance or implicitly indicating the number of the indicated technical features. Therefore, the features defined as "first" and "second" may explicitly or implicitly include one or more of the features. In the description of the present invention, the meaning of "plurality" is two or more, unless otherwise clearly and specifically defined.

[0048] like Figures 1 to 7 As shown, an embodiment of the present invention provides a safe, which is applicable to but not limited to temporarily storing precious metals such as gold and diamonds. In particular, the safe can also be placed in precious metal exchange and storage equipment such as gold exchange machines and safes to transfer precious metals in the gold exchange machines and safes. Specifically, Figures 1 to 4 As shown, the safe includes a box body 10, a door 20 and a door lock assembly 30. The box body 10 is open at the top and has a receiving chamber 11 for receiving precious metals formed therein. When transferring precious metals, the precious metals are received in the receiving chamber 11. The door 20 is hinged at the top of the box body 10. Specifically, one end of the door 20 is hinged to the side of the box body 10 through a hinge 232. The door 20 is used to cover the top opening of the box body 10. A delivery port 21 connected to the receiving chamber 11 is provided on the door 20. When transferring precious metals, the precious metals are delivered into the receiving chamber 11 through the delivery port 21. A shield 22 capable of adapting to cover the delivery port 21 is slidably connected to the door 20. A connecting portion 221 for connecting an external driving member (not shown) is provided on the shield 22. The shield 22 can slide and move under the drive of the external driving member to open or cover the delivery port 21. Figure 2 and Figure 3 Specifically, the external driving member may be, but is not limited to, a driving member disposed in a cash exchange machine or a safe and capable of reciprocating along the sliding direction of the shield 22. Figure 4As shown, the door lock assembly 30 is installed on the box body 10 and is used to lock the box door 20 on the box body 10. In the present embodiment, the door lock assembly 30 is arranged on the side of the box body 10 opposite to the hinged end of the box door 20. The door lock assembly 30 locks the box door 20 on the box body 10 to ensure that the box door 20 can stably and reliably cover the opening of the box body 10 to prevent the precious metals in the accommodating cavity 11 from pouring out. It can be understood that in the present embodiment, the door lock assembly 30 has two states: locked and unlocked. When the door lock assembly 30 is in the locked state, the box door 20 is locked on the box body 10, and the precious metals are sealed in the accommodating cavity 11. When the door lock assembly 30 is in the unlocked state, the box door 20 is unlocked and can be flipped relative to the box body 10 with the hinge axis as the axis, so as to open the box body 10. At this time, the precious metals in the accommodating cavity 11 can be taken out from the top opening of the box body 10.

[0049] The safe of the embodiment of the present invention has a delivery port 21 connected to the accommodating chamber 11 formed on the door 20. When the precious metal is not transferred, Figure 2 As shown, the shield 22 covers the delivery port 21 to prevent the precious metals contained in the accommodating chamber 11 from pouring out. When the precious metals are delivered, the delivery port 21 is placed just below the precious metal output port of an external delivery device such as a gold exchange machine and a precious metal safe. The external driving member on the external delivery device is connected to the connecting portion 221 on the shield 22. The shield 22 slides and moves under the driving of the external driving member to open the delivery port 21. After the delivery port 21 is opened, the precious metals in the external delivery device can be delivered into the accommodating chamber 11 of the box body 10 through the delivery port 21. Figure 3 In this way, when transferring and depositing precious metals, it is only necessary to control the external driving member on the external delivery device to be connected to the connecting portion 221 on the shutter 22, and the delivery port 21 can be opened synchronously by controlling the movement of the external driving member. In this way, the safe can work in coordination with external delivery devices such as gold exchange machines and precious metal safes. When depositing precious metals, there is no need to manually open and close the shutter 22, and the delivery operation is simpler, thereby effectively improving the transfer and delivery efficiency of precious metals.

[0050] In another embodiment of the present invention, Figures 2 to 4As shown, the box door 20 includes a cover plate 23 and a door panel 24 that are detachably connected. Specifically, the cover plate 23 is locked to the bottom of the door panel 24 by fasteners such as screws. The cover plate 23 is adapted to cover the top opening of the box body 10. The door panel 24 is stacked on the cover plate 23 at intervals and forms an installation cavity 25 with the cover plate 23. The delivery port 21 is opened on the cover plate 23. The door panel 24 is provided with a positioning port 241 that is adapted to the delivery port 21 at a position opposite to the delivery port 21. The shield 22 is installed in the installation cavity 25 and is slidably connected to the cover plate 23 or the door panel 24, and the connecting portion 221 exposes the positioning port 241. When it is necessary to transfer precious metals, the safe of this embodiment is moved to a position where the positioning port 241 faces the precious metal output port on a precious metal delivery device such as a gold exchange machine or a safe, and then the driving member on the precious metal delivery device is moved to be connected to the connecting portion 221, and the driving member drives the shutter 22 to move to open the delivery port 21. At this time, the precious metals in the precious metal delivery device can enter the accommodating cavity 11 through the delivery port 21. In this way, by setting the door panel 24 connected to the cover plate 23 and reserving the installation cavity 25, the shutter 22 is accommodated in the installation cavity 25, and the overall appearance is more beautiful. In addition, a positioning port 241 is opened on the door panel 24, and the positioning port 241 moves to face the output port of the precious metal delivery device, which means that the delivery port 21 is also synchronously moved to face the output port, and the movement reference is more obvious, so that the delivery port 21 and the output port can be effectively prevented from being skewed.

[0051] In another embodiment of the present invention, Figure 2 , Figure 4 and Figure 5 As shown, two slide rails 26 are convexly provided at the positions of the opposite sides of the delivery port 21 at the top of the cover plate 23 or the bottom of the door plate 24, and the length direction of the two slide rails 26 is parallel to the sliding movement direction of the shield plate 22, and the opposite sides of the shield plate 22 are correspondingly clamped in the slide grooves of the two slide rails 26, that is, the two sides of the delivery port 21 are symmetrically provided with two slide rails 26, and the shield plate 22 is limitedly clamped between the two slide rails 26, and the slide rails 26 guide the movement of the shield plate 22, thereby guiding the shield plate 22 to accurately move to open or cover the delivery port 21, and the sliding movement of the shield plate 22 is more accurate. Specifically, in this embodiment, the two slide rails 26 are both arranged at the top of the cover plate 23 or at the bottom of the door plate 24, that is, the shield plate 22 can be slidably connected to the cover plate 23 or the door plate 24.

[0052] In another embodiment of the present invention, Figure 2 and Figure 3As shown, since the driving parts on precious metal delivery devices such as gold exchange machines and safes are often rod-shaped driving parts, such as latches, in this embodiment, the connecting portion 221 is preferably a protrusion protruding from the top edge of the baffle 22, and a slot for inserting an external driving part is provided on the protrusion. When the safe of this embodiment moves to the point where the positioning port 241 is opposite to the output port of the precious metal delivery device, the end of the driving part on the precious metal delivery device can be inserted into the slot on the protrusion. The periphery of the positioning port 241 is symmetrically provided with a first notch 242 and a second notch 243 along the sliding movement direction of the baffle 22. When the baffle 22 covers the delivery port 21, the protrusion is located in the first notch 242. When the external driving part drives the baffle 22 to move to open the delivery port 21, the protrusion moves to be located in the second notch 243. In this way, the distance between the first notch 242 and the second notch 243 is roughly equal to the inner diameter of the delivery port 21. When the protrusion moves from the first notch 242 to the second notch 243, the delivery port 21 can be fully opened. The moving stroke of the shutter 22 is fixed, and the reliability of moving to open or close the delivery port 21 is higher.

[0053] In another embodiment of the present invention, Figure 2 and Figure 3 As shown, the box door 20 also includes a sensing component installed in the installation cavity 25, and the sensing component includes a first micro switch 271 and a second micro switch 272 for detecting the position of the baffle 22. The first micro switch 271 and the second micro switch 272 are arranged at intervals along the sliding movement direction of the baffle 22. Specifically, the first micro switch 271 is arranged at the rear end of the baffle 22, and the second micro switch 272 is arranged at the front end of the baffle 22. When the baffle 22 covers the delivery port 21, one end of the baffle 22 moves to trigger the first micro switch 271, and when the baffle 22 moves to open the delivery port 21, the other opposite end of the baffle 22 moves to trigger the second micro switch 272. In this way, when the first micro switch 271 is triggered, it means that the shutter 22 has moved to completely cover the delivery port 21. Conversely, when the second micro switch 272 is triggered, it means that the shutter 22 has moved to completely open the delivery port 21. The first micro switch 271 and the second micro switch 272 are combined with the first notch 242 and the second notch 243 to move and position the shutter 22, and the movement of the shutter 22 is more precise.

[0054] Furthermore, the first microswitch 271 and the second microswitch 272 can also be connected to an external drive component for communication. In this way, when the first microswitch 271 or the second microswitch 272 is triggered, the external drive component can automatically and synchronously close the drive of the shutter 22. There is no need for the operator to manually control the opening and closing of the external drive component, and the opening and closing process of the delivery port 21 is more automated.

[0055] Specifically, in this embodiment, the first micro switch 271 and the second micro switch 272 can both be mechanical micro switches or inductive micro switches.

[0056] In another embodiment of the present invention, Figure 2 and Figure 3 As shown, the sensing component also includes a first telescopic electromagnet 273 and a third micro switch 274. A limit block 222 is protruding from the end of the baffle 22 near the second micro switch 272. The first telescopic electromagnet 273 is arranged on the side of the baffle 22. The telescopic rod of the first telescopic electromagnet 273 can be telescoped in a direction perpendicular to the sliding movement direction of the baffle 22, and when the baffle 22 covers the delivery port 21, the telescopic rod of the first telescopic electromagnet 273 is extended to abut against the end of the limit block 22 to stop the baffle 22 and limit the baffle 22 above the delivery port 21. When the baffle 22 needs to slide to open the delivery port 21, the telescopic rod of the first telescopic electromagnet 273 can be retracted to move away from the limit block 22. In this way, when there is no need to open the delivery port 21, the telescopic rod of the first telescopic electromagnet 273 stops the baffle 22 to prevent the baffle 22 from sliding autonomously and causing the delivery port 21 to be opened by mistake. When the delivery port 21 needs to be opened, the first telescopic electromagnet 273 is started to retract its telescopic rod away from the limit block 222. At this time, the telescopic rod of the first telescopic electromagnet 273 no longer stops the baffle 22, and the baffle 22 can move under the drive of the external driving member, thereby opening the delivery port 21. The setting of the first telescopic electromagnet 273 will not hinder the normal opening and closing of the baffle 22.

[0057] Furthermore, if Figure 2 and Figure 3 As shown, the third micro switch 274 is arranged beside the first telescopic electromagnet 273, and when the telescopic rod of the first telescopic electromagnet 273 is retracted to be away from the limit block 222, the end of the telescopic rod of the first telescopic electromagnet 273 away from the shield 22 moves to trigger the third micro switch 274. In this way, when it is necessary to open the delivery port 21, the first telescopic electromagnet 273 is first started to retract its telescopic rod, and when the telescopic rod moves to trigger the third micro switch 274, it means that the telescopic rod of the first telescopic electromagnet 273 has completely avoided the limit block 222. At this time, the external driving member drives the shield 22 to move and will no longer be blocked by the telescopic rod.

[0058] Furthermore, the first telescopic electromagnet 273 and the third micro switch 274 may also be connected to an external driving member for communication, thereby realizing intelligent opening and closing of the delivery port 21 .

[0059] Specifically, in this embodiment, the third micro switch 274 can also be a mechanical micro switch or an inductive micro switch.

[0060] In another embodiment of the present invention, Figure 6 and Figure 7 As shown, the door lock assembly 30 includes a lock member 31 rotatably connected to the side of the box body 10, the lock member 31 has a lock hook portion 311, and a locking shaft 231 adapted to hook the lock hook portion 311 is convexly provided at a position of the box door 20 corresponding to the lock hook portion 311. The lock member 31 can switch between a locked state and an unlocked state. When the lock member 31 is in the locked state, the lock hook portion 311 is hooked on the locking shaft 231 to lock the box door 20 to the box body 10. When the lock member 31 is in the unlocked state, the lock member 31 rotates to disengage the lock hook portion 311 from the locking shaft 231 to unlock the box door 20. When it is necessary to take out the precious metal in the accommodating chamber 11, the lock member 31 is rotated to the unlocked state, and the locking shaft 231 on the door 20 is disengaged from the lock hook portion 311 of the lock member 31. The door 20 is no longer constrained by the hook of the lock member 31. The user can manually drive the door 20 to flip to open the box body 10, and then take out the precious metal in the accommodating groove from the top opening of the box body 10.

[0061] Specifically, in this embodiment, Figure 6 and Figure 7 As shown, a locking shaft 231 is protruded from the two side portions of the door panel 24 along the width direction respectively. The locking member 31 is a rod-shaped member whose length is adapted to the width of the door panel 24. The two end portions of the locking member 31 are respectively bent to form two locking hook portions 311. The two locking hook portions 311 can be respectively hooked and connected to the corresponding locking shafts 231. The connection stability between the locking member 31 and the box door 20 is higher, and the locking of the box door 20 is more stable and reliable.

[0062] In another embodiment of the present invention, Figure 6 and Figure 7As shown, the door lock assembly 30 also includes a mechanical lock 32, a lock tongue 33 and a reset spring 34. The mechanical lock 32 is embedded in the box body 10, and the lock tongue 33 is rotatably installed in the box body 10 and is located directly below the lock catch 31. The end of the mechanical lock 32 embedded in the box body 10 is connected to the lock tongue 33. The mechanical lock 32 can drive the lock tongue 33 to rotate to push the lock catch 31, thereby driving the lock catch 31 to rotate synchronously to an unlocked state; specifically, in this embodiment, the mechanical lock 32 can be a common password lock or a lock with a key, and the inner wall surface of the shell 12 is located below the locking shaft 231. There is a convex portion with a lock that is connected to the lock shaft 231. The connecting pin 312 is parallel to the locking shaft 231, and the position where the lock hook portion 311 is bent to form the lock fastener 31 is connected to the shell 12 through the connecting pin 312. When the door 20 needs to be opened, the password is entered or the key is inserted to open the mechanical lock 32. The mechanical lock 32 drives the lock tongue 33 to rotate upward until it is against the lock fastener 31. At this time, the force continues to be applied to drive the lock tongue 33 to rotate, and the lock tongue 33 pushes the lock fastener 31 to rotate around the connecting pin 312, so that the lock hook portion 311 rotates to disengage from the locking shaft 231. At this time, the lock fastener 31 rotates from the locked state to the unlocked state, and the door 20 can be flipped open.

[0063] Furthermore, if Figure 6 and Figure 7 As shown, the return spring 34 is elastically connected between the lock member 31 and the side wall of the box body 10. After the lock tongue 33 drives the lock member 31 to rotate to the unlocked state, the return spring 34 can elastically pull the lock member 31 to rotate in the opposite direction to return to the locked state. The lock member 31 is locked when the locking pin 31 is unlocked and the lock member 31 is locked again.

[0064] In another embodiment of the present invention, Figure 6 and Figure 7As shown, the door lock assembly 30 also includes a second telescopic electromagnet 35 installed on the inner wall of the box body 10, and a plug hole 331 is provided on the lock tongue 33. The telescopic rod of the second telescopic electromagnet 35 can be extended to be inserted into the plug hole 331, and can be retracted to be removed from the plug hole 331. Specifically, when the box door 20 is locked on the box body 10, the telescopic rod of the second telescopic electromagnet 35 is inserted into the plug hole 331 to prevent the lock tongue 33 from rotating incorrectly and causing the box door 20 to be opened incorrectly. When the mechanical lock 32 is needed to open the box door 20, the second telescopic electromagnet 35 is started to retract its telescopic rod to be separated from the lock tongue 33. At this time, the lock tongue 33 can be driven to rotate by the mechanical lock 32, thereby driving the lock catch 31 to rotate to indicate that the box door 20 can be opened normally.

[0065] Furthermore, in this embodiment, if Figure 6 and Figure 7 As shown, the door lock assembly 30 also includes a Hall sensor 36 installed on the box body 10 for sensing the position of the box door 20. The Hall sensor 36 is communicated with the second telescopic electromagnet 35. When the Hall sensor 36 senses that the box door 20 is closed, the information is fed back to the second telescopic electromagnet 35, so that the second telescopic electromagnet 35 is started and its telescopic rod is inserted into the plug hole 331 of the lock tongue 33.

[0066] In another embodiment of the present invention, Figure 4 , Figure 6 and Figure 7 As shown, the box body 10 includes an outer shell 12 with an open top and an inner shell 13 embedded in the outer shell 12 and with an open top. The accommodating cavity 11 is formed in the inner shell 13. An installation gap 131 is reserved between the inner shell 13 and the side wall of the outer shell 12. The door lock assembly 30 is installed in the installation gap 131. In this way, the door lock assembly 30 and the accommodating cavity 11 are isolated from each other, the precious metal in the accommodating cavity 11 does not contact the door lock assembly 30, and the locking and unlocking process of the door lock assembly 30 is not affected by the precious metal in the accommodating cavity 11.

[0067] In another embodiment of the present invention, the safe also includes a controller (not shown) and a positioning module (not shown) and a wireless communication module (not shown) connected to the controller for communication. The wireless communication module is electrically connected to the sensing component. Specifically, the wireless communication module is electrically connected to the first microswitch 271, the second microswitch 272, the third microswitch 274 and the first telescopic electromagnet 273 to obtain the position status information of the baffle. The positioning module and the wireless communication module are both installed in the box body 10, and a battery 40 is also provided in the box body 10 to power the controller. Among them, the positioning module can be used to sense and determine the position of the safe of this embodiment, and locate the safe. When the safe is lost, its location can be determined through the positioning module, so that the safe can be found quickly. Specifically, the positioning module can be a GPRS module commonly used in the market, and the wireless communication module is one of the commonly used 2G mobile communications, 3G mobile communications, 4G mobile communications, 5G mobile communications and narrowband Internet of Things communications in the market. In addition to being electrically connected to the above-mentioned sensing components, the other electric components of the safe of this embodiment can also be electrically connected to the wireless communication module. In this way, the wireless communication module feeds back the action information of the above-mentioned electric components to the controller, and the controller controls the electric components to work together.

[0068] Furthermore, the wireless communication module can also establish communication links with external gold exchange machines, safes and other precious metal delivery equipment through the controller, thereby realizing intelligent collaborative work between the safe of this embodiment and the external gold exchange machine or safe.

[0069] Specifically, Figure 2 , Figure 3 and Figure 6 As shown, the following is a detailed description of the use process of the safe of this embodiment:

[0070] When it is necessary to transfer the precious metals in the gold exchange machine and the safe to the safe deposit box of this embodiment, after the delivery port 21 moves to the output port facing the delivery device, the controller controls the driving member on the gold exchange machine or the safe to move to connect with the connecting part 221, and the controller simultaneously controls the first telescopic electromagnet 273 to start and retract its telescopic rod, and then the driving member drives the shutter 22 to move and open the delivery port 21. When the controller receives the information that the second micro switch 272 is triggered, it indicates that the delivery port 21 is fully opened, and the controller controls the driving member to stop driving the shutter 22. After the precious metals are delivered, the controller controls the driving member to start and drive the shutter 22 to move again. When the controller receives the information that the first micro switch 271 is triggered, it indicates that the delivery port 21 is completely covered. At this time, the controller controls the driving member to stop driving the shutter 22, and controls the telescopic rod of the first telescopic electromagnet 273 to extend to abut against the limit stopper 222 on the shutter 22. When it is necessary to open the door 20 to take out precious metals from the accommodating chamber 11, the controller controls the telescopic rod of the second telescopic electromagnet 35 to retract until it is disengaged from the lock tongue 33, and the door 20 is opened through the mechanical lock 32. After the precious metals are taken out and the door 20 is closed, the Hall sensor 36 feeds back the information that the door 20 is closed to the controller, and the controller then controls the telescopic rod of the second telescopic electromagnet 35 to re-extend until it is inserted into the plug-in hole 331 on the lock tongue 33.

[0071] Specifically, in this embodiment, the controller is preferably an STM32F401 microcontroller. Of course, it can also be a single-chip microcomputer, PLC control device or computer with relatively mature technology. The specific control of the above-mentioned electric components can be carried out according to the program set or edited according to the control and use requirements.

[0072] In another embodiment of the present invention, the box body 10 is also provided with a box-end interface (not shown) for adapting electrical connection with an external interface on an external device, and the box-end interface is electrically connected to the controller. Specifically, in this embodiment, the controller is arranged outside the safe of this embodiment, and can be integrated in a precious metal delivery device such as a gold exchange machine and a safe. The safe of this embodiment is connected to the external interface on the external device through the box-end interface, so that each electric component in the safe is electrically connected to the controller. In this embodiment, the box-end interface can be, but is not limited to, an SP3485 interface.

[0073] In another embodiment of the present invention, Figure 1 , Figure 6 and Figure 7As shown, a spare opening 121 is further opened at a position of the shell 12 near the mechanical lock 32. The spare opening 121 is riveted to the cover plate 23 of the shell 12 by rivets 123. When the mechanical lock 32 cannot normally open the door 20, the cover plate 23 can be removed, and an "L"-shaped wrench or the like can be inserted into the spare opening 121 to drive the lock member 31 to rotate and open the door 20.

[0074] The above description is only a preferred embodiment of the present invention and is not intended to limit the present invention. Any modifications, equivalent substitutions and improvements made within the spirit and principles of the present invention should be included in the protection scope of the present invention.
