Description

Technical Field

[0001] This application relates to the field of safe deposit box technology, and more particularly to an ATM safe deposit box securing device. Background Technology

[0002] An ATM, or Automated Teller Machine, is a small machine set up by banks in various locations. It uses a magnetic stripe on a plastic card about the size of a credit card to record the customer's basic account information (usually a bank card), allowing the customer to perform bank counter services such as withdrawals, deposits, and transfers through the machine.

[0003] In related technologies, the structure of an ATM can be divided into two parts: the upper part is the operating console containing a display screen, keyboard, card reader, receipt printer, etc.; the lower part is a safe for storing the cash box. Typically, staff pre-load the cash box with banknotes to ensure smooth withdrawals; deposits are stored in the cash box, and staff remove the banknotes when the box is full to ensure smooth deposit processing.

[0004] Regarding the aforementioned technologies, the inventors believe that because the safe is heavy, it is inconvenient for staff to put the safe into or take out the ATM when it is necessary to fill or take out banknotes from the cash box. Summary of the Invention

[0005] To address the issue of heavy safes being inconvenient for staff to place or retrieve from ATMs, this application provides an ATM safe securing device.

[0006] The ATM safe fixing device provided in this application adopts the following technical solution:

[0007] An ATM safe-locking device includes an ATM for depositing and withdrawing cash. The ATM has a safety door on its side wall and a safety cavity inside. The safety cavity contains a safe for storing a cash box. The safety cavity is equipped with a sliding mechanism and a driving mechanism. The sliding mechanism slides within the safety cavity under the drive mechanism. The safe for storing the cash box is fixed to the sliding mechanism by a fixing mechanism.

[0008] By adopting the above technical solution, the safe is fixed to the sliding mechanism through a fixing mechanism, and then the sliding mechanism is driven by a driving mechanism to slide, so that the safe can slide out or slide into the safe cavity, thereby improving the convenience of putting the safe into or taking it out of the ATM.

[0009] Optionally, the sliding mechanism includes a sliding base and a plurality of sliding beads. A sliding groove is provided on the side wall adjacent to the side wall where the ATM for depositing and withdrawing cash is located. A plurality of sliding holes are provided on the part of the sliding base located in the sliding groove. A plurality of sliding beads are rotatably installed in a plurality of sliding holes in a corresponding manner. The sliding base is fixed to the driving mechanism.

[0010] By adopting the above technical solution, the sliding friction between the sliding seat and the inner wall of the safe is changed to rolling friction by using a sliding ball, which makes it easier for the drive mechanism to drive the sliding seat so that the safe on the sliding seat can slide out or slide into the safe, thereby further improving the convenience of putting the safe into or taking it out of the ATM.

[0011] Optionally, the driving mechanism includes a drive motor, a drive screw, and a drive protrusion. A driving cavity is formed in the bottom wall of the safety cavity. The drive motor is located in the driving cavity. A driving groove is provided in the bottom wall of the safety cavity facing the safety door. One end of the driving groove is connected to the driving cavity. The drive screw and the drive protrusion are both located in the driving groove. The drive screw is coaxially mounted on the output shaft of the drive motor. The drive protrusion is fixed on the sliding seat. The drive screw is threaded through the drive protrusion.

[0012] By adopting the above technical solution, the drive motor drives the drive screw to rotate, which in turn causes the drive protrusion to slide in the drive groove and drive the sliding seat to slide, so that the safe on the sliding seat can slide out or slide into the safe cavity, thereby saving manpower and further improving the convenience of putting the safe into or taking it out of the ATM.

[0013] Optionally, the fixing component includes a plurality of fixing protrusions, which are disposed on the sliding seat and form a fixing space, within which a safe for storing the cash box is disposed.

[0014] By adopting the above technical solution, the fixed protrusion can play a certain role in fixing and limiting the safe on the sliding seat. Therefore, when the sliding seat moves the safe into or out of the safe cavity, the safe is not easy to slip off the sliding seat, thereby improving the stability of putting the safe into or out of the ATM machine through the drive mechanism.

[0015] Optionally, the safe cavity is provided with a locking mechanism, which includes a locking spring and a locking block. The ATM machine used for depositing and withdrawing cash has a locking groove 1 on the side wall where the sliding groove is located. The locking spring and the locking block are both located in the locking groove 1. One end of the locking spring is fixed to the bottom wall of the locking groove 1, and the other end of the locking spring is fixed to the locking block. The safe for storing cash boxes has a locking groove 2 on the side wall, which corresponds to the locking groove 1. The locking block extends into the locking groove 2 under the drive of the locking spring. The locking block slides between the locking groove 1 and the locking groove 2 through an opening component.

[0016] By adopting the above technical solution, when the safe slides into the safety chamber, the locking block is partially located in the locking groove two under the action of the locking spring, thereby locking the safe in the safety chamber and making the safe difficult to steal; when the safe slides out of the safety chamber, the opening component causes the locking block to slide out of the locking groove two, thereby allowing the safe to be taken out smoothly.

[0017] Optionally, the opening assembly includes a rotating rod, a spur gear, a connecting rod, a rack, and a pair of bevel gears. The ATM machine for depositing and withdrawing cash has a receiving cavity on the side wall opposite to the side wall where the safety door is located. The receiving cavity is connected to the driving cavity. The rotating rod is rotatably mounted on the inner wall of the receiving cavity. The spur gear and one of the bevel gears are coaxially mounted on the rotating rod, and the other bevel gear is coaxially mounted on the output shaft of the drive motor. The pair of bevel gears mesh with each other. The ATM machine for depositing and withdrawing cash also has a second receiving cavity on the side wall where the sliding groove is located. The receiving cavity is connected to the first receiving cavity. The connecting rod is located in the second receiving cavity. The rack is fixed to one end of the connecting rod and meshes with the spur gear. The other end of the connecting rod is fixed to the locking block.

[0018] By adopting the above technical solution, when the safe slides out of the safety chamber, the bevel gear can drive the rotating rod to rotate when the drive motor is turned on, which in turn causes the spur gear on the rotating rod to rotate. As a result, the connecting rod will bring the locking block from the locking groove two into the locking groove one, thus allowing the safe to slide out of the safety chamber. When the safe slides into the safety chamber, the bevel gear drives the rotating rod to rotate in the opposite direction to the spur gear. As a result, the connecting rod will bring the locking block from the locking groove one into the locking groove two, thereby locking the safe.

[0019] Optionally, the sliding seat has a moving groove along the axial direction of the drive screw at one end facing the drive protrusion, and the drive protrusion is slidably disposed in the moving groove.

[0020] By adopting the above technical solution, when the safe needs to be removed, the drive motor is turned on, and the drive protrusion will slide a certain distance in the moving groove, so that the opening component can first bring the locking block out of the locking groove two; after the opening component brings the locking block out of the locking groove two, the drive protrusion is pressed against the groove wall of the moving groove, so that the sliding seat can be pushed out of the safe cavity.

[0021] Optionally, a limiting groove 1 is formed on the wall of the moving groove, the limiting groove 1 is connected to the driving groove, and a limiting mechanism is provided in the limiting groove 1. The limiting mechanism includes a limiting spring and a limiting plate. One end of the limiting spring is fixed to the bottom wall of the limiting groove 1, and the other end of the limiting spring is fixed to the limiting plate. The limiting plate is rotatably installed on the side of the limiting groove 1 away from the safety door. A limiting groove 2 is provided on the driving protrusion corresponding to the limiting groove 1. The limiting plate is flipped into the limiting groove 2 under the drive of the limiting spring. One end of the limiting plate extends into the driving groove and abuts against the bottom wall of the driving groove. A guide component is provided on the bottom wall of the driving groove.

[0022] By adopting the above technical solution, when the driving protrusion abuts against the wall of the moving groove, the limiting plate flips into the limiting groove two under the action of the limiting spring, thereby limiting the driving protrusion. This allows the driving protrusion to push the sliding seat into the safety cavity by abutting against the limiting plate, thus reserving a certain space in the moving groove. This allows the driving protrusion to continue sliding after the sliding seat has completely slid into the safety cavity and the guide component has pushed the limiting plate out of the limiting groove two. This allows the driving screw to continue rotating and the opening component to bring the locking block back into the locking groove two, thereby locking the safe.

[0023] Optionally, the guide assembly includes a guide ridge, which is disposed on the bottom wall of the drive groove along the length direction of the drive groove, and the guide ridge is located on the side of the limiting plate facing the drive protrusion.

[0024] By adopting the above technical solution, the guide ridge can push the limiting plate out of the limiting groove two after the sliding seat is completely slid into the safety cavity, so that the driving ridge can continue to slide in the moving groove, thereby enabling the driving screw to continue to rotate and the opening component to bring the locking block back into the locking groove two, thus realizing the locking of the safe.

[0025] Optionally, the ATM for depositing and withdrawing cash has a receiving cavity three on its side wall. The receiving cavity three is connected to the safety cavity and the locking groove one. The receiving cavity three is provided with a stop assembly, which includes a stop rod and a stop spring. The stop rod includes a pair of stop parts and a connecting part disposed between the pair of stop parts. One end of the stop spring is fixed to the inner wall of the receiving cavity three, and the other end of the stop spring is fixed to the connecting part. The locking block has a stop hole. One of the stop parts is inserted into the stop hole under the drive of the stop spring, and the other stop part extends into the safety cavity under the drive of the stop spring.

[0026] By adopting the above technical solution, when the opening component brings the locking block into the locking groove, one of the stop parts is inserted into the stop hole under the action of the stop spring, so that the locking block will not pop out of the locking groove due to the action of the locking spring, thereby allowing the safe to slide back into the safe cavity. At the same time, it can also limit the linkage from moving towards the spur gear under the action of the locking spring, reducing the possibility of the rack and spur gear grinding.

[0027] In summary, this application includes at least one of the following beneficial technical effects:

[0028] 1. The safe is fixed to the sliding mechanism by a fixing mechanism, and then the sliding mechanism is driven by a drive mechanism to slide, so that the safe can slide out or slide into the safe cavity, thereby improving the convenience of putting the safe into or taking it out of the ATM.

[0029] 2. By using sliding beads to change the sliding friction between the sliding seat and the inner wall of the safe into rolling friction, the drive mechanism can more easily drive the sliding seat, so that the safe on the sliding seat can slide out or slide into the safe, thereby further improving the convenience of putting the safe into or taking it out of the ATM.

[0030] 3. The drive motor drives the lead screw to rotate, which in turn causes the drive protrusion to slide in the drive groove and drive the sliding seat to slide, so that the safe on the sliding seat can slide out or slide into the safe cavity, thereby saving manpower and further improving the convenience of putting the safe into or taking it out of the ATM.

Detailed Implementation

[0037] The following is in conjunction with the appendix Figure 1-5 This application will be described in further detail.

[0038] This application discloses an ATM safe securing device. (Refer to...) Figure 1 and Figure 2 The ATM safe fixing device includes an ATM 1 and a safety door 2 hinged to the side wall of the ATM 1. A safety cavity 3 for storing a safe 4 is formed inside the ATM 1. A sliding mechanism 5 is provided within the safety cavity 3, allowing the safe 4 to slide out or into the safety cavity 3. Specifically, the sliding mechanism 5 includes a sliding base 51 and several sliding beads 52. Sliding grooves 11 are provided on both inner walls of the ATM 1 adjacent to the safety door 2, and these grooves 11 are horizontally oriented and extend towards the safety door 2.

[0039] Reference Figure 2 and Figure 3The sliding seat 51, located within the sliding groove 11, has a plurality of sliding holes 511 densely distributed along the opening direction of the sliding groove 11. A plurality of sliding beads 52 are rotatably installed in the plurality of sliding holes 511, corresponding to each other, and abut against the bottom wall of the sliding groove 11. In addition, a fixing mechanism 7 is provided on the upper surface of the sliding seat 51. Specifically, the fixing mechanism 7 includes a plurality of fixing protrusions 71, which are welded to the sliding seat 51 and enclose a fixed space. The safe 4 is placed within the fixed space on the sliding seat 51.

[0040] Therefore, under the fixing action of the fixed protrusion 71, the safe 4 can be restricted to a designated position on the sliding seat 51. When the sliding seat 51 slides, the safe 4 can be driven by the sliding seat 51 and is not easy to deviate, so it can slide out or slide into the safe cavity 3. At the same time, the sliding ball 52 is used to change the sliding friction between the sliding seat 51 and the inner wall of the safe cavity 3 into rolling friction, thereby improving the convenience of putting the safe 4 into the ATM 1 or taking it out of the ATM 1.

[0041] Reference Figure 4 The safe compartment 3 is also equipped with a drive mechanism 6. Specifically, the drive mechanism 6 includes a drive motor 61, a drive screw 62, and a drive protrusion 63. A drive cavity 12 is formed in the side wall of the ATM 1 opposite to the safe door 2. The drive motor 61 is installed in the drive cavity 12. In addition, a drive groove 13 is provided on the bottom wall of the safe compartment 3 facing the safe door 2. The drive groove 13 is connected to the drive cavity 12. The drive screw 62 and the drive protrusion 63 are both located in the drive groove 13. The drive protrusion 63 is fixed to the sliding seat 51. The drive screw 62 is coaxially mounted on the output shaft of the drive motor 61 and threaded through the drive protrusion 63. Therefore, the drive motor 61 can drive the drive screw 62 to rotate, thereby causing the drive protrusion 63 to slide along the opening direction of the drive groove 13, so as to drive the sliding seat 51 to slide out or slide into the safe compartment 3, thereby further improving the convenience of putting the safe 4 into or taking it out of the ATM 1.

[0042] Reference Figure 5Since the safe 4 is not directly fixed to the ATM 1 after adopting the above solution, a locking mechanism 9 is also provided in the safe cavity 3 to consider security issues. Specifically, the locking mechanism 9 includes a locking spring 91 and a locking block 92. The ATM 1 has a locking groove 14 on the side wall where the sliding groove 11 is located. The safe 4 has a locking groove 41 on the side wall corresponding to the locking groove 14. One end of the locking spring 91 is fixed to the bottom wall of the locking groove 14, and the other end is fixed to the locking block 92. Under the force of the locking spring 91, the locking block 92 extends into the locking groove 41, thus locking the safe 4 when it is located in the safe cavity 3. In this embodiment, in order to make the safe 4 have high security when stored in the safe cavity 3, the locking mechanism 9 is provided as a pair, with the pair of locking mechanisms 9 corresponding to each other on both sides of the safe 4.

[0043] Reference Figure 4 and Figure 5 The safe 3 is equipped with an opening component 10. The opening component 10 controls the sliding of the locking block 92 between the locking groove 14 and the locking groove 41, thereby controlling the locking and unlocking of the safe 4. Specifically, the opening component 10 includes a rotating rod 101, a spur gear 102, a connecting rod 103, a rack 104, and a pair of bevel gears 105. A receiving cavity 15 is vertically provided in the side wall opposite to the safe door 2 of the ATM 1. The receiving cavity 15 is connected to the drive cavity 12. The rotating rod 101 is located in the receiving cavity 15, with one end rotatably mounted on the groove wall of the receiving cavity 15 and the other end extending towards the drive motor 61. One bevel gear 105 is coaxially mounted on the output shaft of the drive motor 61, and the other bevel gear 105 is coaxially mounted on the rotating rod 101. The pair of bevel gears 105 mesh. Therefore, when the drive motor 61 starts, the rotating rod 101 also starts to rotate simultaneously.

[0044] Within the side wall of the ATM 1 containing the first receiving cavity 15, the second receiving cavity 16 is horizontally provided. The second receiving cavity 16 is connected to the first receiving cavity 15, and both ends of the second receiving cavity 16 extend towards the adjacent side walls of the ATM 1 until they connect with the first locking groove 14. A connecting rod 103 is located within the second receiving cavity 16. The connecting rod 103 is L-shaped, with one end extending towards the rotating rod 101 and the other end extending towards and welded to the locking block 92. A rack 104 is fixed to the end of the connecting rod 103 near the rotating rod 101. A spur gear 102 is mounted on the rotating rod 101 and meshes with the rack 104. Therefore, when the drive motor 61 is started, the rotating rod 101 rotates, causing the spur gear 102 to move the connecting rod 103, thereby bringing the locking block 92 out of or into the second locking groove 41, thus controlling the unlocking and locking of the safe 4.

[0045] Reference Figure 4 and Figure 5To enable the drive mechanism 6, the opening component 10, and the locking mechanism 9 to operate together, it is important to note that the connecting rod 103 needs to be set to a length that allows it to disengage from the spur gear 102 just as the locking block 92 is pulled out of the locking groove 41. This ensures that the spur gear 102 does not continuously drive the connecting rod 103 while the drive motor 61 is continuously operating to push the sliding seat 51 out of the safety chamber 3. Furthermore, since the spring force applied by the locking spring 91 to the locking block 92 will push the connecting rod 103 towards the spur gear 102, to reduce the possibility of tooth knocking between the rack 104 and the spur gear 102, a receiving cavity 3 17 is provided on the side wall of the ATM machine 1. The receiving cavity 3 17 is U-shaped, with one end connected to the safety chamber 3 and the other end connected to the locking groove 14.

[0046] The receiving cavity 3 17 is equipped with a stop assembly 22. Specifically, the stop assembly 22 includes a stop rod 221 and a stop spring 222. The stop rod 221 consists of a pair of stop portions 2211 and a connecting portion 2212 integrally formed between the pair of stop portions 2211. One stop portion 2211 extends toward the locking block 92, and the locking block 92 is provided with a stop hole 921 for the stop portion 2211 to be inserted. The other stop portion 2211 extends toward the safe cavity 3 and abuts against the side wall of the safe 4. One end of the stop spring 222 is fixed to the inner wall of the receiving cavity 3 17, and the other end is fixed to the connecting portion 2212. Under the action of the stop spring 222, the stop rod 221 tends to move toward the safe door 2.

[0047] Reference Figure 3 and Figure 5 To enable the drive motor 61 to unlock the safe 4 via the locking mechanism 9 through the opening component 10 before the drive sliding seat 51 pushes the safe 4 out of the safety cavity 3, the sliding seat 51 has a moving groove 512 on the side facing the drive screw 62. The drive protrusion 63 is actually partially embedded in the moving groove 512, and the length of the moving groove 512 is greater than the length of the drive protrusion 63. When the safe 4 is completely inside the safety cavity 3, the drive protrusion 63 is located at the end of the moving groove 512 closest to the drive motor 61.

[0048] Therefore, when the drive motor 61 is turned on and drives the drive protrusion 63 to push the sliding seat 51, the drive protrusion 63 will move a certain distance in the moving groove 512 until it presses against the groove wall of the moving groove 512 away from the drive motor 61, so as to provide a certain running space for the opening component 10 to bring the locking block 92 out of the locking groove 41. When the drive protrusion 63 presses against the groove wall of the moving groove 512 away from the drive motor 61, the opening component 10 just brings the locking block 92 out of the locking groove 41, the safe 4 is unlocked, and the drive protrusion 63 can push the sliding seat 51 to send the safe 4 out of the safety cavity 3. At the same time, the locking groove 14 and the locking groove 2 41 are misaligned. The locking block 92 is pressed against the side wall of the safe 4 and is located in the locking groove 14. The safe 4 is no longer pressed against the stop rod 221. The stop rod 221 will move towards the safety door 2 under the force of the stop spring 222 and finally the stop part 2211 is inserted into the stop hole 921 to restrict the locking block 92 in the locking groove 14. Therefore, the connecting rod 103 will not be pushed towards the spur gear 102 by the locking block 92 under the force of the locking spring 91, thereby reducing the occurrence of tooth knocking between the rack 104 and the spur gear 102. At the same time, it also ensures that the locking block 92 will not obstruct the safe 4 when the safe 4 is put back into the safety cavity 3.

[0049] Reference Figure 3 and Figure 5 In order to enable the drive motor 61 to continue to lock the safe 4 by controlling the locking mechanism 9 through the opening component 10 after the drive sliding seat 51 sends the safe 4 into the safety cavity 3, a limiting groove 1 513 is provided on the side wall of the moving groove 512, and a limiting groove 2 631 is provided on the drive protrusion 63 corresponding to the limiting groove 1 513. A limiting mechanism 20 is provided in the limiting groove 1 513. The limiting mechanism 20 includes a limiting spring 201 and a limiting plate 202. One end of the limiting spring 201 is fixed to the bottom wall of the limiting groove 1 513, and the other end is fixed to the limiting plate 202. The limiting plate 202 is rotatably installed on the side of the limiting groove 1 513 away from the safety door 2. The limiting plate 202 has a tendency to flip outward from the limiting groove 1 513 under the drive of the limiting spring 201.

[0050] In addition, a guide component 21 is provided on the bottom wall of the drive groove 13. The guide component 21 is a guide protrusion 211. The guide protrusion 211 is set along the length direction of the drive groove 13. The limiting groove 513 extends downward through the moving groove 512. The bottom of the limiting plate 202 extends out of the limiting groove 513 and abuts against the bottom wall of the drive groove 13. The guide protrusion 211 is located on the side of the limiting plate 202 facing the drive protrusion 63. The side of the guide protrusion 211 that is close to the limiting plate 202 is set as a matching arc surface. The guide protrusion 211 gradually narrows towards the safety door 2.

[0051] Therefore, when the drive motor 61 drives the drive protrusion 63 to push the sliding seat 51 toward the safety door 2, the first limiting groove 513 corresponds to the second limiting groove 631. The limiting plate 202 cannot flip into the second limiting groove 631 due to the obstruction of the guide protrusion 211. However, as the drive protrusion 63 moves toward the safety door 2, the guide protrusion 211 gradually narrows, and the limiting plate 202 will eventually flip into the second limiting groove 631 under the action of the limiting spring 201. Therefore, when the drive motor 61 drives the drive protrusion 63 to push the sliding seat 51 into the safety cavity 3, the drive protrusion 63 is limited by the limiting plate 202. Therefore, it cannot move forward in the moving groove 512 and can only push the sliding seat 51 into the safety cavity 3 by pressing against the limiting plate 202. When the driving protrusion 63 moves to the position of the guide protrusion 211, the guide protrusion 211 will gradually push the limiting plate 202 out of the limiting groove 631 as the driving protrusion 63 continues to move into the safety cavity 3. When the sliding seat 51 is completely slid into the safety cavity 3, the limiting plate 202 is completely pushed out of the limiting groove 631. The driving protrusion 63 can continue to move in the moving groove 512 to provide a certain operating space for the opening component 10 to bring the locking block 92 into the locking groove 41.

[0052] Meanwhile, since the safe 4 is completely located inside the safety cavity 3, the stop rod 221 is pressed against by the safe 4 and slides away from the safety door 2. The stop part 2211 slides out from the stop hole 921. At this time, the locking spring 91 pushes the locking block 92 to drive the connecting rod 103 to move toward the spur gear 102, and makes the rack 104 re-engage with the spur gear 102. Therefore, the opening component 10 can bring the locking block 92 back into the locking groove 41, realize the locking operation of the safe 4, and lock the safe 4 inside the safety cavity 3, which has a high security.

[0053] The implementation principle of the ATM safe fixing device according to this application embodiment is as follows: The safe 4 is fixed to the sliding seat 51 by a fixing protrusion 71. Two sides of the sliding seat 51 are correspondingly embedded in the sliding grooves 11 on the two side walls of the ATM 1. The portion of the sliding seat 51 located in the sliding groove 11 has a plurality of sliding holes 511 densely distributed along the opening direction of the sliding groove 11. A plurality of sliding beads 52 are rotatably installed in the plurality of sliding holes 511 and abut against the bottom wall of the sliding groove 11. The driving protrusion 63 is fixed to the sliding seat, and the driving screw 62 is coaxially mounted on the output shaft of the driving motor 61 and threaded through the driving protrusion 63. Therefore, the driving motor 61 can drive the driving screw 62 to rotate, thereby causing the driving protrusion 63 to slide along the opening direction of the driving groove 13, so as to drive the sliding seat to slide out or slide into the safe cavity 3, thereby improving the convenience of putting the safe 4 into or taking it out of the ATM 1.

[0054] The above are all preferred embodiments of this application and are not intended to limit the scope of protection of this application. Therefore, all equivalent changes made to the structure, shape and principle of this application should be covered within the scope of protection of this application.
