Description

Technical Field

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

[0002] Gold realization refers to the process in which consumers convert their gold holdings into cash through a series of means. With the rapid development of social economy, the amount of gold held by consumers has gradually increased, and the demand for gold realization has also increased. However, there are very few channels for gold and other precious metals to be realized. Many consumers realize their gold in cash through street gold shops, gold stores, and pawnshops. Although such realization methods can realize gold quickly, the realization process is irregular and opaque. It is common for the recycling party to defraud consumers by recycling at a low price. In addition, banks also have formal precious metal recycling channels, but banks generally only accept investment bars sold by their own units, and there are few recycling outlets and cumbersome transaction procedures. 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, realize the rapid exchange between precious metals and cash, effectively solve the problem of gold realization for consumers, and help realize the social circulation of gold and other precious metals.

[0003] Generally, after the gold exchange machine recovers gold, it needs to be transferred to a safe for temporary storage, and then transported to a bank or other precious metal storage institution for storage. Existing safes / cabinets usually control the opening and closing of the door by setting a mechanical lock inside the box. When transferring the precious metals in the gold exchange machine to the safe / cabinet, the operator needs to manually open the box / cabinet door of the safe / cabinet 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 box / cabinet door is manually closed. The safe / cabinet cannot work autonomously with the gold exchange machine to complete the autonomous transfer of precious metals. The precious metal transfer process is cumbersome to operate, and the transfer efficiency is difficult to effectively improve. Summary of the invention

[0070] 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.

[0071] like Figures 1 to 14 As shown, one embodiment of the present invention provides a precious metal storage device, which is suitable for being arranged inside an intelligent gold exchange machine and is used to store precious metals put into the gold exchange machine. Figures 1 to 4As shown, the precious metal storage device includes a safe 50, which can be adapted to be installed in the body of the gold exchange machine. The safe 50 includes a cabinet body 52 with a side opening and a first accommodating cavity 51 inside, and a cabinet door 53 locked to the side of the cabinet body 52 and used to close the side opening. A first delivery port 521 connected to the first accommodating cavity 51 is opened on the top of the cabinet body 52, and a first cover plate 522 that can adapt to cover the first delivery port 521 is slidably connected to the cabinet body 52. ​​When the safe 50 is installed in the gold exchange machine, the first delivery port 521 is located directly below the channel for conveying precious metals in the gold exchange machine, so that the precious metals put into the gold exchange machine can fall into the safe 50 through the first delivery port 521.

[0072] Furthermore, if Figures 2 to 4 As shown, the precious metal storage device also includes a safe 100, an opening and closing drive mechanism 60 and a controller (not shown in the figure). The safe 100 is adapted to be accommodated in the first accommodating cavity 51 and can be taken out from the side opening. When the precious metals stored in the safe 100 reach their storage upper limit, the empty safe 100 can be replaced; the top of the safe 100 is provided with a second delivery port 21 arranged opposite to the first delivery port 521, and the safe 100 is slidably connected with a second cover plate 22 adapted to cover the second delivery port 21. The opening and closing drive mechanism 60 is installed on the cabinet 52 and is used to control the synchronous opening or closing of the first delivery port 521 and the second delivery port 21. Specifically, the opening and closing drive mechanism 60 includes a transmission member 61 and a drive assembly 62. The transmission member 61 connects the first baffle 522 and the second baffle 22. The driving end of the drive assembly 62 is connected to the first baffle 522. The drive assembly 62 can drive the first baffle 522 to slide and move, and drive the transmission member 61 to drive the second baffle 22 to move synchronously, thereby synchronously opening or closing the first delivery port 521 and the second delivery port 21. The controller is electrically connected to the electric component of the drive assembly 62 to control the opening or closing of the drive assembly 62, thereby controlling the automatic opening or closing of the first delivery port 521 and the second delivery port 21.

[0073] Specifically, in this embodiment, the controller can be a control chip independently arranged on the safe 50 or the safe 100, and the control chip is connected to the control system of the gold exchange machine. When the user uses the gold exchange machine, the control chip obtains the operation information of the gold exchange machine control system, thereby controlling the start or shut down of the drive component 62. For example, the controller can be an STM32F401 microcontroller. In other embodiments, the controller can also be a relatively mature single-chip microcomputer, PLC control device or computer, etc., and its specific control of the above-mentioned drive component 62 can be performed according to the program set or edited according to the control and use requirements; the controller can also be a control module integrated in the control system of the gold exchange machine, that is, the precious metal storage device of this embodiment as a whole is an internal sub-device of the gold exchange machine, and is uniformly and collaboratively controlled by the gold exchange machine.

[0074] The precious metal storage device provided by the embodiment of the present invention is as follows: Figure 3 and Figure 4 As shown, when in use, the safe 50 containing the safe 100 is installed in the gold exchange machine. When someone uses the gold exchange machine, the controller controls the drive assembly 62 to open, and the drive assembly 62 drives the transmission member 61 to drive the first baffle 522 and the second baffle 22 to move synchronously, so as to synchronously open the first delivery port 521 and the second delivery port 21. At this time, the precious metals put in from the gold exchange machine can fall into the safe 100 through the first delivery port 521 and the second delivery port 21; after the precious metals are put in, the controller controls the drive assembly 62 to drive the first baffle 522 and the second baffle 22 to move synchronously, and close the first delivery port 521 and the second delivery port 21. The precious metals put into the gold exchange machine can be temporarily stored in the safe 100. When the precious metals stored in the safe 100 reach the storage limit, the cabinet door 53 is opened to take the safe 100 out of the safe 50 and transport it to a bank or other precious metal sealing institution for sealing. In this way, the gold exchange machine can achieve coordinated work with the safe 50 and the safe 100 through the controller. The first delivery port 521 on the safe 50 and the second delivery port 21 on the safe 100 can be opened and closed automatically. There is no need to manually open and close the delivery ports when delivering precious metals. The precious metal delivery operation is simpler, and the efficiency of precious metal delivery and transfer is effectively improved.

[0075] In another embodiment of the present invention, Figure 2 , Figure 3 and Figure 4 As shown, the safe 50 further includes a mounting plate 90 accommodated in the first accommodating cavity 51, the mounting plate 90 is installed at intervals on the inner top surface of the cabinet 52, and a mounting cavity 91 is formed between the inner top surfaces of the cabinet 52, and the opening and closing drive mechanism 60 is installed in the mounting cavity 91, so that the opening and closing drive mechanism 60 is accommodated in the cabinet 52 as a whole, and the appearance of the safe 50 is more neat and beautiful. Further, a connecting port 92 is also opened at the position of the mounting plate 90 facing the first delivery port 521, and the setting of the mounting plate 90 will not affect the precious metal from hindering the precious metal from being input into the safe 100.

[0076] In another embodiment of the present invention, Figure 2 , Figure 3 and Figure 4As shown, a connecting rod 5221 is protruded from the bottom of the first baffle 522, and the first end of the transmission member 61 is slidably connected to the connecting rod 5221. The second end of the transmission member 61 is suspended on the top of the second baffle 22. The top of the second baffle 22 is provided with a slot 221 for the second end of the transmission member 61 to be adapted and plugged in. The opening and closing drive mechanism 60 also includes a first drive motor 63 installed beside the transmission member 61 and electrically connected to the controller. The driving end of the first drive motor 63 is connected to the transmission member 61 to drive the transmission member 61 to slide up and down along the connecting rod 5221 so that the second end of the transmission member 61 is inserted into or removed from the slot 221. When the first delivery port 521 and the second delivery port 21 are in the closed state, the second end of the transmission member 61 is located outside the slot 221. When the first delivery port 521 and the second delivery port 21 need to be opened, the controller controls to start the first drive motor 63, and the first drive motor 63 drives the transmission member 61 to slide downward along the connecting rod 5221 until the second end is inserted into the slot 221. At this time, the two ends of the transmission member 61 are respectively connected to the first baffle 522 and the second baffle 22. The controller controls to start the drive assembly 62 to drive the first baffle 522 to move, which can drive the second baffle 22 to move synchronously, thereby realizing the synchronous opening or closing of the first delivery port 521 and the second delivery port 21. In this way, when the safe 100 in the safe 50 needs to be replaced, the first drive motor 63 drives the transmission member 61 to slide upward along the connecting rod 5221, so that the second end thereof is pulled out from the slot 221. In this way, the setting of the transmission member 61 will not hinder the normal replacement of the safe 100, and it is more convenient to use.

[0077] Specifically, in this embodiment, Figure 2 , Figure 3 and Figure 4As shown, a sliding block 631 is screwed on the output shaft of the first driving motor 63, and the output shaft of the first driving motor 63 is arranged perpendicular to the transmission member 61. A connecting protrusion 611 protrudes from the side of the transmission member 61, and an inclined connecting slot 632 is provided on the sliding block 631. The connecting protrusion 611 is adapted to be connected to the connecting slot 632. When the first driving motor 63 is started, the rotation of its output shaft drives the sliding block 631 to make reciprocating linear motion in the direction perpendicular to the transmission member 61, so that the connecting protrusion 611 moves back and forth between the two ends of the connecting slot 632; when the connecting protrusion 611 moves to the bottom end of the connecting slot 632, the second end of the transmission member 61 is disengaged from the slot 221, and when the connecting protrusion 611 moves to the top end of the connecting slot 632, the second end of the transmission member 61 is inserted into the slot 221. In addition, a first micro switch 65 communicatively connected to the controller is also provided on the side of the sliding block 631 away from the first driving motor 63. The sliding block 631 can press and trigger the first micro switch 65 when the connecting protrusion 611 moves to the bottom of the connecting slot 632. At this time, the transmission member 61 is pulled out of the slot 221, and the first micro switch 65 feeds back the information that the transmission member 61 is pulled out of the slot 221 to the controller. In this way, when the first delivery port 521 and the second delivery port 21 are closed, the first driving motor 63 drives the transmission member 61 to move upward along the connecting rod 5221, so that the second end of the transmission member 61 is pulled out of the slot 221. The first micro switch 65 feeds back the pulling-out information to the controller after the transmission member 61 is completely pulled out. The user can know the linkage status of the first baffle 522 and the second baffle 22 through the controller at this time.

[0078] In another embodiment of the present invention, Figure 3 and Figure 4 As shown, the driving assembly 62 is a linear driving module, and the driving axis of the linear driving module is parallel to the moving direction of the first baffle 522. Specifically, the driving assembly 62 includes a screw rod 621 that is arranged along the moving direction of the first baffle 522 and can rotate, a moving nut 622 that is threadedly connected to the screw rod 621, a connecting block 623 that is fixedly connected to the moving nut 622 and connected to the first baffle 522, and a module motor 624 that is connected to one end of the screw rod 621. In this way, the module motor 624 rotates, drives the screw rod 621 to rotate, drives the moving nut 622 to move linearly, and the first baffle 522 that is fixedly connected to the connecting block 623 can slide and move. In addition, the driving assembly 62 also includes a guide rail 625 that guides and supports the movement of the first baffle 522, and the first baffle 522 is slidably connected to the two guide rails 625 through a slider 626.

[0079] Furthermore, in this embodiment, if Figure 3 and Figure 4As shown, the drive assembly 62 also includes a gear bayonet 627 rotatably mounted on the mounting plate 90 and a bayonet telescopic electromagnet 628 electrically connected to the controller. A rotating gear (not shown) is sleeved on the output shaft of the module motor 624. The gear bayonet 627 has a connecting end and a holding end. The gear bayonet 627 is rotatably mounted on the mounting plate 90. The connecting end of the gear bayonet 627 is connected to the telescopic rod of the bayonet telescopic electromagnet 628. When the telescopic rod of the bayonet telescopic electromagnet 628 is extended, the holding end of the gear bayonet 627 rotates to abut against the rotating gear to stop the rotating gear from rotating. When the telescopic rod of the bayonet telescopic electromagnet 628 is retracted, the holding end of the gear bayonet 627 rotates away from the rotating gear, and the rotating gear rotates normally. In this way, when the drive assembly 62 is abnormally started, the emergency stop can be controlled by the gear bayonet 627.

[0080] In another embodiment of the present invention, Figure 3 and Figure 4 As shown, the opening and closing drive mechanism 60 also includes a first sensor 64 installed at intervals beside the first baffle 522 and connected to the controller for communication. The first sensor 64 is used to sense and obtain the moving position information of the first baffle 522. Specifically, when the first baffle 522 moves to cover the first delivery port 521, or when the first baffle 522 moves to the first delivery port 521 and is fully opened, the first sensor 64 feeds back the corresponding information to the controller, and the controller immediately controls the closing drive assembly 62. In this way, the first sensor 64 is set to accurately sense the position information of the first baffle 522 to avoid deviation in the moving position of the first baffle 522. In this embodiment, the first sensor 64 can be a photoelectric sensor or the like.

[0081] In another embodiment of the present invention, Figure 1 , Figure 2 , Figure 5 and Figure 6As shown, the cabinet door 53 is hinged to the cabinet body 52, and the safe 50 also includes a cabinet lock mechanism 70 installed on the cabinet door 53 and used to lock the cabinet door 53 to the cabinet body 52. ​​Specifically, the cabinet door 53 is hollow inside, and the cabinet lock mechanism is installed in the cabinet door 53. The cabinet lock mechanism 70 includes a locking member 71 slidably installed on the inner side wall of the cabinet door 53, and the locking member 71 has a locking portion 711. A locking groove 523 for the locking portion 711 to be adapted and inserted is provided at a position of the cabinet body 52 corresponding to the locking portion 711. The locking member 71 can switch between a locked state and an unlocked state. When the locking member 71 is in the locked state, the locking portion 711 is inserted into the locking groove 523 to lock the cabinet door 53 to the cabinet body 52. ​​When the locking member 71 is in the unlocked state, the locking member 71 slides and moves until the locking portion 711 is disengaged from the locking groove 523 to unlock the cabinet door 53. When it is necessary to take out the safe 100 in the safe 50, the locking member 71 is moved to the unlocked state, and the locking portion 711 of the locking member 71 is disengaged from the locking groove 523 on the cabinet body 52. ​​The user can manually drive the cabinet door 53 to rotate around its hinge axis to open the cabinet body 52, and then take out the safe 100 in the safe 50 from the side opening of the cabinet body 52. ​​The operation is very convenient.

[0082] Furthermore, in this embodiment, if Figure 2 , Figure 5 and Figure 6 As shown, the cabinet lock mechanism 70 also includes a first drive member 72 and a second drive motor 73 electrically connected to the controller. The first drive member 72 is slidably installed on the inner wall of the cabinet body 52, and the sliding movement direction of the first drive member 72 is parallel to the sliding movement direction of the locking member 71. The opposite ends of the first drive member 72 are respectively connected to the locking member 71 and the output ends of the second drive motor 73. The second drive motor 73 drives the first drive member 72 to move, thereby driving the locking member 71 to move, so that the locking portion 711 is inserted into or removed from the locking groove 523.

[0083] Specifically, Figure 5 and Figure 6As shown, the locking member 71 includes a transverse locking plate 712 and two longitudinal locking plates 713. The transverse locking plate 712 is provided with a first connecting buckle 714. The end of the first driving member 72 away from the second driving motor 73 is hooked and connected to the first connecting buckle 714. The side of the transverse locking plate 712 away from the first driving member 72 is provided with a plug-in column. The two longitudinal locking plates 713 are vertically connected to the two opposite side parts of the transverse connecting block 623 and are linked with the transverse locking plate 712. The sides of the two longitudinal locking plates 713 away from the transverse locking plate 712 are respectively provided with a plug-in column. The plug-in column on the transverse locking plate 712 and the two plug-in columns on the two longitudinal locking plates 713 form the locking portion 711 of the locking member 71. In this way, the plug-in columns at three positions cooperate with the three side locking grooves 523 of the cabinet body 52, so that the cabinet door 53 can be more firmly and reliably locked to the cabinet body 52. When it is necessary to open the cabinet door 53, the controller controls the second drive motor 73 to start, and the second drive motor 73 drives the first drive member 72 to pull the transverse locking plate 712 and the two longitudinal locking plates 713 to move until the plug-in column is removed from the locking groove 523. At this time, the cabinet door 53 can be opened. Conversely, when closing the cabinet door 53, the controller controls the second drive motor 73 to drive the first drive member 72 to push the transverse locking plate 712 and the two longitudinal locking plates 713 in the opposite direction to move them until the plug-in column is reinserted into the locking groove 523. The operation is simple.

[0084] In another embodiment of the present invention, Figure 5 and Figure 6 As shown, the cabinet lock mechanism 70 also includes a mechanical lock 74, a paddle 75, and a second driving member 76. The mechanical lock 74 is embedded in the cabinet door 53, the paddle 75 is rotatably mounted on the inner side wall of the cabinet door 53, and the second driving member 76 is slidably mounted on the inner side wall of the cabinet body 52, and the sliding movement direction of the second driving member 76 is parallel to the sliding movement direction of the locking member 71. One end of the second driving member 76 is connected to the locking member 71. Specifically, the transverse locking plate 712 is located at the first connecting buckle 71. A second connecting buckle 715 is protruded at the upper position of 14, and the end of the second driving member 76 away from the mechanical lock 74 is hooked and connected to the second connecting buckle 715, one end of the paddle 75 is connected to the end of the mechanical lock 74 embedded in the cabinet door 53, and the mechanical lock 74 can drive the paddle 75 to rotate until it abuts against the other end of the second driving member 76, so as to drive the second driving member 76 to slide and drive the locking member 71 to slide, so that the locking portion 711 is inserted into or pulled out of the locking groove 523.

[0085] Specifically, in this embodiment, Figure 5 and Figure 6As shown, the mechanical lock 74 can be a common password lock or a lock with a key. When the cabinet door 53 needs to be opened, the password is entered or the key is inserted to open the mechanical lock 74. The mechanical lock 74 drives the paddle 75 to rotate until it abuts against the end of the second drive member 76. Then, the paddle 75 is driven to rotate until the paddle 75 abuts against the second drive member 76 to pull the locking member 71, that is, pull the transverse locking plate 712 and the two longitudinal locking plates 713, until the plug-in column is out of the locking groove 523. At this time, the locking member 71 can also move to the unlocked state, and the cabinet door 53 can be opened. In this way, the mechanical lock 74 is set to control the locking member 71 to switch the use state, ensuring that when the second drive motor 73 or the first drive member 72 is abnormal, the cabinet door 53 can be opened by the mechanical lock 74.

[0086] Furthermore, in this embodiment, if Figure 5 and Figure 6 As shown, the cabinet door 53 is further provided with a first telescopic electromagnet 78 at a position below the first driving member 72. The first driving member 72 and the second driving member 76 are arranged side by side up and down, and the first driving member 72 and the second driving member 76 can be pushed and moved up and down by the telescopic rod of the first telescopic electromagnet 78. Specifically, when the telescopic rod of the first telescopic electromagnet 78 is in an extended state, it can push the first driving member 72 to move away from the first connecting buckle 714, and at the same time make the second driving member 76 move to hook onto the second connecting buckle 715. At this time, the first driving member 72 is no longer connected to the locking member 71, and the second driving motor 73 cannot control the movement of the locking member 71, but can only control the movement of the locking member 71 through the mechanical lock 74.

[0087] Furthermore, in this embodiment, if Figure 5 and Figure 6 As shown, the cabinet door 53 is also equipped with a second sensor 79 for sensing the locking position of the locking member 71. The second sensor 79 is connected to the controller for communication. When the locking member 71 moves to the locking portion 711 and inserts into the locking groove 523, or when the locking member 71 moves to the locking portion 711 and escapes from the locking groove 523, the second sensor 79 feeds back corresponding information to the controller, and the controller immediately controls to turn off the second drive motor 73. In this way, the second sensor 79 can accurately sense the position information of the locking member 71 to avoid locking deviation of the locking member 71. In this embodiment, the second sensor 79 can also be a photoelectric sensor or the like.

[0088] In another embodiment of the present invention, Figure 5 and Figure 6As shown, the cabinet lock mechanism 70 also includes a first sensor 77 disposed on the cabinet door 53 and communicatively connected to the controller. The first sensor 77 is used to sense and obtain the opening and closing state information of the cabinet door 53, so as to ensure that the controller can timely control the second drive motor 73 to close after the cabinet door 53 is opened or opened. Specifically, in this embodiment, the first sensor 77 is preferably a Hall sensor, and a permanent magnet used in conjunction with the first sensor 77 is installed at the position of the cabinet body 52 facing the first sensor 77. When the cabinet door 53 is closed, the first sensor 77 is affected by the permanent magnet and outputs a door closing signal to the controller. On the contrary, when the cabinet door 53 is opened, the first sensor 77 is not affected by the permanent magnet and outputs a door opening signal to the controller.

[0089] In another embodiment of the present invention, Figure 2 and Figure 7 As shown, a limiting assembly 80 for limiting the storage position of the safe 100 is also provided in the cabinet 52, and the limiting assembly 80 includes a first limiting plate 81, a second limiting plate 82 and a limiting pressure plate 83. The first limiting plate 81 and the second limiting plate 82 are arranged in parallel and spaced apart on both sides of the cabinet 52, and the spacing distance between the first limiting plate 81 and the second limiting plate 82 is equal to the width of the safe 100. When the safe 100 is placed in the safe 50, the first limiting plate 81 and the second limiting plate 82 can play a role in limiting the storage position of the safe 100. In order to play the role of positioning guidance, the limiting pressure plate 83 is clamped between the first limiting plate 81 and the second limiting plate 82, and the distance between the end of the limiting pressure plate 83 away from the cabinet door 53 and the side wall of the cabinet body 52 facing the cabinet door 53 is equal to the length of the safe 100. In this way, after the safe 100 is placed in place, it is stopped by the limiting pressure plate 83 in the first accommodating cavity 51 and will not be displaced during use, thereby ensuring that the second delivery port 21 is always facing the first delivery port 521, providing guarantee for the accurate delivery of precious metals.

[0090] Furthermore, if Figure 2 and Figure 7As shown, the end of the limiting pressure plate 83 close to the cabinet door 53 is hinged to the first limiting plate 81 and the second limiting plate 82 through a torsion spring (not shown), etc., and a clamping arm 831 is protruded on both sides of the end of the limiting pressure plate 83 away from the cabinet door 53, and the first limiting plate 81 and the second limiting plate 82 are provided with limiting holes 811 for corresponding insertion of the two clamping arms 831. When the limiting pressure plate 83 is not pressed by the safe 100, the end of the limiting pressure plate 83 away from the cabinet door 53 is in the torsion spring state. The locking arm 831 is in a lifted state under the action of the torsion spring, and the locking arm 831 is located at the top of the limiting hole 811. When the safe 100 is placed, the safe 100 presses the limiting pressure plate 83 downward, and the end of the limiting pressure plate 83 away from the cabinet door 53 is in contact with the inner bottom surface of the cabinet body 52, and the plug-in arm moves to the bottom of the limiting hole 811. When the safe 100 is placed in place, the limiting pressure plate 83 is no longer pressed by the safe 100, and its end away from the cabinet door 53 bounces upward under the action of the torsion spring. In this way, when the safe 100 is placed, by observing the state of the limiting pressure plate 83, it can be judged whether the safe 100 is installed in place.

[0091] Furthermore, in this embodiment, if Figure 2 and Figure 7 As shown, a third sensor 84 for sensing the position state of the limit pressure plate 83 is also installed at the position of the first limit plate 81 or the second limit plate 82 near the plug-in arm. The third sensor 84 is connected to the controller for communication. When the clamping arm 831 of the limit pressure plate 83 rebounds to the top of the clamping hole, the third sensor 84 feeds back the information to the controller, and the controller determines that the safe 100 has been installed in place. In this embodiment, the third sensor 84 can also be a photoelectric sensor, etc.

[0092] Furthermore, a photoelectric sensor (not shown) in communication with the controller may be disposed on the inner top surface of the cabinet 52 near the first loading port 521 to detect whether a safe 100 is placed in the first accommodating cavity 51 .

[0093] In another embodiment of the present invention, Figure 2 and Figure 4 As shown, a connection terminal 524 electrically connected to the controller is provided on the inner side wall of the cabinet body 52 facing the cabinet door 53, and a connection interface 101 for the connection terminal 524 to be adapted and plugged is provided at the position of the safe 100 facing the connection terminal 524. The electric components of the safe 100 are electrically connected to the controller through the connection interface 101. In this way, the controller can realize the coordinated control of the safe 100, so that the precious metal storage device of this embodiment has a higher degree of automation and intelligence, and is more flexible and convenient to use. Specifically, in this embodiment, the connection terminal 524 can be but not limited to a 485 communication interface, and the connection interface 101 can be but not limited to an SP3485 interface.

[0094] In another embodiment of the present invention, Figure 1 , Fig. 9 , Fig.10 and Fig.11 As shown, the safe 100 of the precious metal storage device of this embodiment includes a box body 10, a box door 20 and a door lock assembly 30. The top of the box body 10 is open and a second accommodating chamber 11 for accommodating precious metals is formed inside. When the precious metals are transferred, the precious metals are accommodated in the second accommodating chamber 11. The box door 20 is hinged to the top of the box body 10. Specifically, one end of the box door 20 is hinged to the side of the box body 10 through a hinge 232. The box door 20 is used to cover the top opening of the box body 10. The second delivery port 21 is opened on the box door 20 and communicates with the second accommodating chamber 11. When the precious metals are transferred, the precious metals are dropped into the second accommodating chamber 11 through the second delivery port 21. The second baffle 22 is slidably connected to the box door 20, as shown in FIG. Fig. 9 and Fig.10 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 this embodiment, the door lock assembly 30 is arranged on the side of the box body 10 facing 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 metal in the second accommodating chamber 11 from pouring out. It can be understood that in this 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 metal is sealed in the second accommodating chamber 11. When the door lock assembly 30 is in the unlocked state, the box door 20 is unlocked and can be turned 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 metal in the second accommodating chamber 11 can be taken out from the top opening of the box body 10.

[0095] In another embodiment of the present invention, Figures 9-11As shown, the box door 20 includes a detachably connected cover plate 23 and a door panel 24. 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 second delivery port 21 is opened on the cover plate 23. The door panel 24 is provided with a positioning port 241 adapted to the second delivery port 21 at a position opposite to the second delivery port 21. The second baffle 22 is installed in the installation cavity 25 and is slidably connected to the cover plate 23 or the door panel 24. The connecting portion 221 exposes the positioning port 241. In this way, by setting the door panel 24 connected to the cover plate 23 and reserving the installation cavity 25, the second baffle 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 is moved to be opposite to the output port of the precious metal delivery equipment, which means that the second delivery port 21 is also synchronously moved to be opposite to the output port, and the movement reference is more obvious, thereby effectively avoiding the second delivery port 21 from being skewed with the output port.

[0096] In another embodiment of the present invention, Fig. 9 , Fig.11 and Fig.13 As shown, two slide rails 26 are convexly provided at the positions of the opposite sides of the second 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 second baffle 22, and the opposite sides of the second baffle 22 are correspondingly clamped in the slide grooves of the two slide rails 26, that is, the two sides of the second delivery port 21 are symmetrically provided with two slide rails 26, and the second baffle 22 is limitedly clamped between the two slide rails 26, and the slide rails 26 guide the movement of the second baffle 22, so as to guide the second baffle 22 to accurately move to open or cover the second delivery port 21, and the sliding movement of the second baffle 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 second baffle 22 can be slidably connected to the cover plate 23 or the door plate 24.

[0097] In another embodiment of the present invention, Fig. 9 and Fig.10As shown, the end of the transmission member 61 is inserted into the slot 221, and the periphery of the positioning opening 241 is symmetrically provided with a first notch 242 and a second notch 243 along the sliding movement direction of the second baffle 22. When the second baffle 22 covers the second delivery opening 21, the slot 221 is located in the first notch 242. When the transmission member 61 drives the second baffle 22 to move to open the second delivery opening 21, the slot 221 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 equal to the inner diameter of the second delivery opening 21. When the slot 221 moves from the first notch 242 to the second notch 243, the second delivery opening 21 can be fully opened. The moving stroke of the second baffle 22 is fixed, and the reliability of moving to open or close the second delivery opening 21 is higher.

[0098] In another embodiment of the present invention, Fig. 9 and Fig.10 As shown, the box door 20 also includes a sensing component installed in the installation cavity 25, and the sensing component includes a second microswitch 271 and a third microswitch 272 for detecting the position of the second baffle 22. The second microswitch 271 and the third microswitch 272 are arranged at intervals along the sliding movement direction of the second baffle 22. Specifically, the second microswitch 271 is arranged at the rear end of the second baffle 22, and the third microswitch 272 is arranged at the front end of the second baffle 22. When the second baffle 22 covers the second delivery port 21, one end of the second baffle 22 moves to trigger the second microswitch 271. When the second baffle 22 moves to open the second delivery port 21, the other end of the second baffle 22 moves to trigger the third microswitch 272. Thus, when the second micro switch 271 is triggered, it indicates that the second shutter 22 has moved to completely cover the second delivery port 21. Conversely, when the third micro switch 272 is triggered, it indicates that the second shutter 22 has moved to completely open the second delivery port 21. The second micro switch 271 and the third micro switch 272 move and position the second shutter 22 in combination with the first notch 242 and the second notch 243, and the second shutter 22 moves more accurately. Specifically, in this embodiment, the second micro switch 271 and the third micro switch 272 can both be mechanical micro switches or inductive micro switches.

[0099] Furthermore, the second microswitch 271 and the third microswitch 272 are communicatively connected to the controller, so that when the second microswitch 271 or the third microswitch 272 is triggered, the transmission member 61 can automatically and synchronously stop driving the second baffle 22, and the opening and closing process of the second delivery port 21 is more automated.

[0100] In another embodiment of the present invention, Fig. 9 and Fig.10As shown, the sensing component also includes a second telescopic electromagnet 273 and a fourth micro switch 274. A limit stopper 222 is convexly provided at the end of the second baffle 22 near the third micro switch 272. The second telescopic electromagnet 273 is arranged beside the second baffle 22. The telescopic rod of the second telescopic electromagnet 273 can be telescoped in a direction perpendicular to the sliding movement direction of the second baffle 22. When the second baffle 22 covers the second delivery port 21, the telescopic rod of the second telescopic electromagnet 273 is extended to abut against the end of the limit stopper 222 to stop the second baffle 22 and limit the second baffle 22 to the top of the second delivery port 21. When the second baffle 22 needs to slide to open the second delivery port 21, The telescopic rod of the second telescopic electromagnet 273 can be retracted to a position away from the limit block 222; in this way, when there is no need to open the second delivery port 21, the telescopic rod of the second telescopic electromagnet 273 stops the second baffle 22 to prevent the second baffle 22 from sliding autonomously and causing the second delivery port 21 to be opened by mistake. When the second delivery port 21 needs to be opened, the second telescopic electromagnet 273 is started to retract its telescopic rod away from the limit block 22. At this time, the telescopic rod of the second telescopic electromagnet 273 no longer stops the second baffle 22, and the second baffle 22 can move under the drive of the transmission member 61, thereby opening the second delivery port 21. The setting of the second telescopic electromagnet 273 will not hinder the normal opening and closing of the second baffle 22.

[0101] Furthermore, if Fig. 9 and Fig.10 As shown, the fourth micro switch 274 is arranged beside the second telescopic electromagnet 273, and when the telescopic rod of the second telescopic electromagnet 273 is retracted to be away from the limit block 222, the end of the telescopic rod away from the second baffle 22 moves to trigger the fourth micro switch 274. In this way, when the second delivery port 21 needs to be opened, the second telescopic electromagnet 273 is first started to retract its telescopic rod. When the telescopic rod moves to trigger the fourth micro switch 274, it means that the telescopic rod has completely avoided the limit block 222. At this time, the transmission member 61 drives the second baffle 22 to move and will no longer be blocked by the telescopic rod. Further, the second telescopic electromagnet 273 and the fourth micro switch 274 can also be connected to the controller for communication, so as to realize the intelligent opening and closing of the second delivery port 21. Specifically, in this embodiment, the fourth micro switch 274 can also be a mechanical micro switch or an inductive micro switch.

[0102] In another embodiment of the present invention, Fig.13 and Fig.14As 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 second 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 second accommodating chamber 11 from the top opening of the box body 10.

[0103] Specifically, in this embodiment, Fig.13 and Fig.14 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 dimension 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.

[0104] In another embodiment of the present invention, Fig.13 and Fig.14 As shown, the door lock assembly 30 also includes a mechanical door lock 32, a lock tongue 33 and a reset spring 34. The mechanical door 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 member 31. The end of the mechanical door lock 32 embedded in the box body 10 is connected to the lock tongue 33. The mechanical door lock 32 can drive the lock tongue 33 to rotate to push the lock member 31, thereby driving the lock member 31 to rotate synchronously to an unlocked state. Specifically, in the present embodiment, the mechanical door lock 32 can be a common password lock or a lock with a key. A connecting pin 312 parallel to the locking shaft 231 is convexly provided on the inner wall surface of the shell 12 below the locking shaft 231. The position where the lock hook portion 311 is bent to form the lock catch 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 door lock 32. The mechanical door lock 32 drives the lock tongue 33 to rotate upward until it is against the lock catch 31. At this time, the force is continued to drive the lock tongue 33 to rotate. The lock tongue 33 pushes the lock catch 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 catch 31 rotates from the locked state to the unlocked state, and the door 20 can be flipped open.

[0105] Furthermore, if Fig.13 and Fig.14 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.

[0106] In another embodiment of the present invention, Fig.13 and Fig.14 As shown, the door lock assembly 30 also includes a third 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 third 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 third telescopic electromagnet 35 is plugged 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 door lock 32 is needed to open the box door 20, the third 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 door lock 32, thereby driving the lock catch 31 to rotate to indicate that the box door 20 can be opened normally.

[0107] Furthermore, in this embodiment, if Fig.13 and Fig.14 As shown, the door lock assembly 30 also includes a second sensor 36 mounted on the box body 10 for sensing the box door 20. The second sensor 36 is in communication connection with the third telescopic electromagnet 35. When the second sensor 36 senses that the box door 20 is closed, the information is fed back to the third telescopic electromagnet 35, so that the third telescopic electromagnet 35 is started and the telescopic rod is inserted into the plug hole 331 of the lock tongue 33. Preferably, in this embodiment, the second sensor 36 is preferably a Hall sensor.

[0108] In another embodiment of the present invention, Fig.11 , Fig.13 and Fig.14 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.
