Description

Technical Field

[0001] The invention relates to the technical field of bank money transport equipment, in particular to a cash box. Background Art

[0002] my country's cash mainly includes banknotes and coins. In order to ensure the efficiency of transportation, general cash escort mainly involves the escort of banknotes.

[0003] In the prior art, for example, Chinese patent application number: CN 109448222 A discloses a temporary storage and transportation box for residual coins used for cash escort, comprising a box body, one side of the box body is hingedly connected to a box door, a plurality of horizontally arranged placement plates are equidistantly arranged in the box body, both sides of the placement plates are provided with a first slider, the inner side wall of the box body is provided with a first slide corresponding to the first slider, the side of the placement plate away from the box door is provided with a second slider, and the inner side wall of the box body is provided with a second slide corresponding to the second slider. The present invention facilitates the classified storage of banknotes of different exchange situations by setting a plurality of placement plates, avoids re-arrangement at a later time, and improves the working efficiency of the bank; by adjusting the position of the placement plates, the space of the residual coin storage and transportation box is reallocated to adapt to the number of banknotes of different exchange situations; due to the torsion of the torsion spring, it is convenient for the pressure plate to clamp the residual coins, and prevent the bumps generated during the cash escort process, which makes the residual coins loose.

[0004] However, the above patents have the following deficiencies:

[0005] Each banking system has its own storage vault to ensure the safety of cash. In order to cope with the daily circulation of cash, the banknotes need to be taken out of the vault and then dispersed among multiple bank facades by transportation equipment. In order to ensure the safety of cash during transportation, it is necessary to use cash boxes with strong protection. The equipment involved in the above patent improves the structural layout of traditional banknote boxes, adds a variety of cooperative components, and adopts physical and mechanical methods to temporarily clamp and fix the banknotes placed in the box, so as to avoid the impact of bumps on the banknotes in the box during transportation. However, there are still some shortcomings. During the transportation process of the cash transporter, there is a small probability that many accidents will occur, such as illegal robbery and aging of the vehicle body, which leads to the loss of some banknote boxes. The above equipment still adopts a single-layer shell protection mode. When the shell cover is illegally pried open, the cash stored in the box can be obtained, and the equipment cannot win sufficient time for the positioning components contained in the box, and ultimately irreversible economic losses occur.

[0006] So we have proposed a cash box to solve the above-mentioned problems. Summary of the invention

[0007] The object of the present invention is to provide a cash box. Through an active locking mechanism connected to the upper box body, the mechanism adopts a mechanical transmission method to quickly complete the double protection of the equipment, fully lock and seal the box body inside the shell. After the outer shell is damaged, illegal persons still need to carry out more difficult box body disassembly, which takes a longer time. At the same time, the positioning components in the box body can quickly feedback the location of the equipment to the bank monitoring system to solve the problems raised in the above background technology.

[0008] To achieve the above object, the present invention provides the following technical solution: A cash box, comprising a lower shell and an upper shell. A lower box body is fixedly installed inside the lower shell, and an upper box body is movably arranged inside the upper shell;

[0009] An active locking mechanism is arranged inside the upper box body, and a magnetic absorption lifting mechanism is arranged inside the upper shell;

[0010] The active locking mechanism includes two first rectangular grooves. Transverse connecting plates are fixedly installed between the two inner walls on both sides of the two first rectangular grooves. A group of round holes are opened inside the two transverse connecting plates, and a pneumatic push rod is fixedly installed inside each round hole. The output end of each pneumatic push rod is welded with an alloy insertion rod. A limiting buckle is fixedly sleeved on the outer surface wall of each alloy insertion rod. An inner groove is opened at the bottom of the lower box body. Two groups of matching holes are opened inside the lower box body, and the number of each group of matching holes is equal to that of the alloy insertion rods. First track grooves are opened on both inner walls of the inner groove. Two groups of assembly rods are fixedly installed on the top inner wall of the inner groove, and the number of each group of assembly rods is equal to that of the alloy insertion rods. A linkage gear is movably sleeved on the outer surface wall of each assembly rod, and the teeth of every two linkage gears are connected by meshing. A support frame is welded on the outer surface wall of each linkage gear, and an arc-shaped clamping sleeve is fixedly sleeved on the outer surface wall of each support frame. The outer surface walls of each group of arc-shaped clamping sleeves are respectively placed inside the first track grooves, and the inner diameter of each arc-shaped clamping sleeve is adapted to the outer diameter of the alloy insertion rod.

[0011] Preferably, a positioning sleeve is fixedly installed on the top inner wall of the inner groove. A positive and negative drive motor is fixedly inserted into the inner surface wall of the positioning sleeve. The output end of the positive and negative drive motor is fixedly connected with a transmission rod. A driving gear is fixedly sleeved on the outer surface wall of the transmission rod. By setting the positive and negative drive motor, when the positive and negative drive motor is turned on, it can slowly drive the driving gear to rotate forward and backward. Under the meshing connection of the driving gear and the row of teeth, it can provide power support for the second-stage work of the mechanism.

[0012] Preferably, two tracks are fixedly installed at the top of the inner wall of the inner groove. T-shaped sliding rods are movably arranged inside the two tracks. Tooth rows are fixedly sleeved on the outer surfaces of the two T-shaped sliding rods. The tooth portions of the two tooth rows are meshed with the driving gear. Force rods are fixedly inserted inside the two tooth rows. By providing the T-shaped sliding rods and using the movable connection between the tracks and the T-shaped sliding rods, under the condition of starting the forward and reverse driving motor, the tooth rows are capable of moving left and right, which is used to control the closing and expansion of the support frame and provides conditions for locking the alloy insertion rod.

[0013] Preferably, joints are fixedly installed on the outer surfaces of two of the two groups of support frames. External connection rods are fixedly inserted between the top and bottom of the inner walls of the two joints. Hollow sleeves are movably sleeved on the outer surfaces of the two external connection rods. One ends of the outer walls of the two force rods are respectively fixedly inserted inside the hollow sleeves. By providing the hollow sleeves, since there will be angular changes whether the support frame expands or closes, the movable connection between the external connection rods and the hollow sleeves can be used to avoid the restraint on the force rods caused by the angle surface, and prevent the problem of deformation or fracture of the component due to excessive external force.

[0014] Preferably, a second rectangular groove is opened at the top of the inner wall of the upper box body. A tracker is fixedly connected to the top of the inner wall of the second rectangular groove. A group of first information lines are fixedly connected to the connection terminals of the tracker. The output ends of the group of first information lines are all connected to the internal wiring of the device. By providing the tracker, it is used to monitor the position of the box body in real time, and its signal transmission method is fed back to the bank monitoring system by satellite, so as to avoid the risk of signal shielding and provide conditions for quickly finding the lost box body.

[0015] Preferably, the magnetic absorption lifting mechanism includes an assembly groove. The assembly groove is opened at the top of the inner wall of the upper shell. An electromagnetic plate and a vibration sensor are respectively arranged inside the assembly groove. A group of second information lines are fixedly connected to the connection terminals of the vibration sensor. The output ends of the group of second information lines are all connected to the input end of the electromagnetic plate. By providing the electromagnetic plate and using the principle of magnetization of induced current, the component has magnetism when it is energized and the magnetism disappears after power-off, so that the working state on the surface of the electromagnetic plate can be flexibly controlled, which is used to adsorb the upper box body and can be separated from the top of the lower shell together with the upper shell.

[0016] Preferably, a third rectangular groove is formed in the top of the upper box body, a metal plate is fixedly installed inside the third rectangular groove, second track grooves are formed in both sides of the inner wall of the upper shell, limiting plates are movably inserted into the two second track grooves, and the opposite sides of the two limiting plates are respectively fixedly installed on both sides of the outer wall of the upper box body. By providing the limiting plates and using the movable connection between the second track grooves and the limiting plates, the upper box body can be separated from the inside of the upper shell. When the upper shell is illegally damaged, the upper box body can still protect the cash inside the box body.

[0017] Preferably, outer edges are fixedly installed on the outer surfaces of both the lower shell and the upper shell. A lock core hole is provided inside one of the two outer edges, an external key is inserted into the lock core hole, and an input window is arranged at the top of the external key. By providing the external key, the person who legally opens the box body needs to input fingerprints in the input window and can open the multiple protections included in the box body after being authorized by the box body system.

[0018] Preferably, a set of trapezoidal lock tongues are movably arranged at the top of one of the two outer edges, a set of lock grooves are formed in the top of the other outer edge, and the outer walls of each trapezoidal lock tongue are adapted to the inner walls of the lock grooves. After each trapezoidal lock tongue is inserted into the lock groove, the lower shell can be fully fixed to the top of the lower shell. The up and down movement of the trapezoidal lock tongue in this process is spontaneous. This is the first layer of protection for the device. When the device is in daily use, the second layer of protection is in a dormant state, which can effectively reduce the energy consumption inside the device and ensure the continuous working ability of the device.

[0019] Preferably, the two first rectangular grooves are respectively formed in both sides of the inner wall of the upper box body, outer grooves are formed in both sides of the outer wall of one of the two outer edges, and handrails are welded inside the two outer grooves. To determine the connection relationship between the first rectangular groove and the whole device, the handrails are provided for lifting the upper shell and the upper box body. The operator can firmly hold the handrails to ensure the sufficiency of the external force applied and reduce the difficulty of opening the upper shell and the upper box body.

[0020] Compared with the prior art, the beneficial effects of the present invention are:

[0021] 1. The present invention adopts an independent inner box structure. When legally opened, the outer shell and the box body can be combined with each other through the cooperation of specific components, thus simplifying the cumbersome process of opening the box. Since the probability of special events is relatively low, the device adopts a single-layer protection principle during normal use. When the outer shell of the device is illegally pried, the corresponding components send an opening instruction to the active locking mechanism according to the vibration intensity. During the process, the mechanism uses mechanical transmission to quickly complete the double-layer protection of the device, fully locking and sealing the box body inside the shell. Therefore, after the outer shell is damaged, the illegal person still needs to carry out more difficult box body disassembly, which takes a longer time. At the same time, the positioning components inside the box can quickly feedback the location of the device to the bank monitoring system, effectively solving the deficiencies of the above-mentioned patent, further enhancing the protection intensity and self-adaptive ability of the cash box, and winning a longer search time for the recovery of the cash in the box. This can avoid increasing the difficulty of solving the subsequent case after the cash is lost.

[0022] 2. The opening of the double-layer protection of the device in the present invention requires obtaining corresponding conditions. When the device is in normal use, the protection component is in a dormant state, which can reduce the consumption of the stored energy of the device by the power-consuming components and ensure the continuous working ability of the device.

[0037] Next, the technical solutions in the embodiments of the present invention will be clearly and completely described in conjunction with the accompanying drawings in the embodiments of the present invention. Obviously, the described embodiments are only a part of the embodiments of the present invention, rather than all the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those of ordinary skill in the art without creative efforts shall fall within the protection scope of the present invention.

[0038] Please refer to the attached Figure 1 - attached Figure 9 As shown in the figure, the present invention provides a technical solution: a cash box, including a lower housing 1 and an upper housing 2. A lower box body 3 is fixedly installed inside the lower housing 1, an upper box body 4 is movably arranged inside the upper housing 2, an active locking mechanism 5 is arranged inside the upper box body 4, and a magnetic absorption lifting mechanism 6 is arranged inside the upper housing 2.

[0039] According to Figures 1-4As shown in the figure, the active locking mechanism 5 includes two first rectangular grooves 501. Between the two inner walls of the two first rectangular grooves 501, cross-connecting plates 502 are fixedly installed. A group of round holes are opened inside the two cross-connecting plates 502, and a pneumatic push rod 503 is fixedly installed inside each round hole. The output end of each pneumatic push rod 503 is welded with an alloy insertion rod 504. A limiting retaining buckle 505 is fixedly sleeved on the outer surface wall of each alloy insertion rod 504. An inner groove 506 is opened at the bottom of the lower box body 3. Two groups of matching holes 507 are opened inside the lower box body 3, and the number of each group of matching holes 507 is equal to that of the alloy insertion rods 504. First track grooves 508 are opened on both inner walls of the inner groove 506. Two groups of assembly rods 513 are fixedly installed at the top of the inner wall of the inner groove 506, and the number of each group of assembly rods 513 is equal to that of the alloy insertion rods 504. A linkage gear 514 is movably sleeved on the outer surface wall of each assembly rod 513, and the teeth of every two linkage gears 514 are meshed. A support frame 515 is welded on the outer surface wall of each linkage gear 514. An arc-shaped clamping sleeve 516 is fixedly sleeved on the outer surface wall of each support frame 515. The outer surface walls of each group of arc-shaped clamping sleeves 516 are respectively placed inside the first track grooves 508, and the inner diameter of each arc-shaped clamping sleeve 516 is adapted to the outer diameter of the alloy insertion rod 504.

[0040] According to Figures 4-5 As shown in the figure, a positioning sleeve 509 is fixedly installed at the top of the inner wall of the inner groove 506. A positive and reverse drive motor 510 is fixedly inserted into the inner surface wall of the positioning sleeve 509. The output end of the positive and reverse drive motor 510 is fixedly connected with a transmission rod 511. A driving gear 512 is fixedly sleeved on the outer surface wall of the transmission rod 511. By setting the positive and reverse drive motor 510, when the positive and reverse drive motor 510 is started, it can slowly drive the driving gear 512 to rotate forward and backward. Under the meshing connection between the driving gear 512 and the row of teeth 519, it can provide power support for the work of the mechanism in the second stage.

[0041] According to Figure 5 and Figure 9 As shown in the figure, two tracks 517 are fixedly installed at the top of the inner wall of the inner groove 506. A T-shaped sliding rod 518 is movably arranged inside each of the two tracks 517. A row of teeth 519 is fixedly sleeved on the outer surface wall of each of the two T-shaped sliding rods 518. The teeth of the two rows of teeth 519 are meshed with the driving gear 512. A stress rod 522 is fixedly inserted into each of the two rows of teeth 519. By setting the T-shaped sliding rod 518, using the movable connection between the track 517 and the T-shaped sliding rod 518, under the condition of starting the positive and reverse drive motor 510, the row of teeth 519 has the ability to move left and right, which is used to control the closing and expansion of the support frame 515 and provide conditions for locking the alloy insertion rod 504.

[0042] According to Figures 4-5As shown, connectors 520 are fixedly installed on the outer surfaces of two of the two sets of support frames 515. External rods are fixedly inserted between the top and bottom of the inner walls of the two connectors 520. Hollow sleeves 521 are movably sleeved on the outer surfaces of the two external rods. One ends of the outer walls of the two stress rods 522 are respectively fixedly inserted into the interiors of the hollow sleeves 521. By setting the hollow sleeves 521, since there will be angle changes whether the support frames 515 expand or close, the movable connection between the external rods and the hollow sleeves 521 can be utilized to avoid the restriction on the stress rods 522 caused by the angle surface, and prevent the problem of deformation or fracture of this component due to excessive external force.

[0043] According to Figure 3 As shown, a second rectangular groove 523 is formed in the top of the inner wall of the upper box body 4. A tracker 524 is fixedly connected to the top of the inner wall of the second rectangular groove 523. A group of first information lines 525 are fixedly connected to the wiring terminals of the tracker 524. The output ends of the group of first information lines 525 are all connected to the internal wiring of the device. By setting the tracker 524, it is used to monitor the position of the box body in real time. The model of this component is TK-102b, and the signal transmission method is fed back to the bank monitoring system by satellite, so as to avoid the risk of signal shielding and provide conditions for quickly finding the lost box body.

[0044] According to Figure 2 and Figure 6 As shown, the magnetic absorption lifting mechanism 6 includes an assembly groove 601, which is formed in the top of the inner wall of the upper shell 2. An electromagnetic plate 602 and a vibration sensor 603 are respectively arranged inside the assembly groove 601. A group of second information lines 604 are fixedly connected to the wiring terminals of the vibration sensor 603. The output ends of the group of second information lines 604 are all connected to the input end of the electromagnetic plate 602. By setting the electromagnetic plate 602, using the principle of magnetization by induced current, the component has magnetism when it is energized and the magnetism disappears after power-off, and the working state on the surface of the electromagnetic plate 602 can be flexibly controlled, which is used to adsorb the upper box body 4 and can be separated from the top of the upper shell 2 together with the lower shell 1.

[0045] According to Figures 6-7 As shown, a third rectangular groove 605 is formed in the top of the upper box body 4. A metal plate 606 is fixedly installed inside the third rectangular groove 605. Second track grooves 607 are formed on both sides of the inner wall of the upper shell 2. Limit plates 608 are movably inserted into the interiors of the two second track grooves 607. The opposite sides of the two limit plates 608 are respectively fixedly installed on both sides of the outer wall of the upper box body 4. By setting the limit plates 608, using the movable connection between the second track grooves 607 and the limit plates 608, the upper box body 4 can be separated from the inside of the upper shell 2. When the upper shell 2 is illegally damaged, the upper box body 4 can still protect the cash inside the box.

[0046] According toFigures 1-2 and Figure 8 As shown in Figure 8 , outer edges 7 are fixedly installed on the outer walls of the lower housing 1 and the upper housing 2. A lock core hole 8 is provided inside one of the two outer edges 7. An external key 9 is inserted into the lock core hole 8. An input window 10 is provided at the top of the external key 9. By setting the external key 9, the person who legally opens the box needs to input their fingerprint in the input window 10. After being authorized by the box system, the multiple protections included in the box can be opened.

[0047] According to Figures 1-2 and Figure 8 As shown in Figure 8 , a set of trapezoidal lock tongues 11 are movably provided at the top of one of the two outer edges 7, and a set of lock grooves 12 are provided at the top of the other outer edge 7. The outer walls of each trapezoidal lock tongue 11 are adapted to the inner walls of the lock grooves 12. When each trapezoidal lock tongue 11 is inserted into the lock grooves 12, the upper housing 2 can be fully fixed to the top of the lower housing 1. The up and down movement of the trapezoidal lock tongue 11 during this process is spontaneous. This is the first layer of protection for the device. When the device is in daily use, the second layer of protection is in a dormant state, thereby effectively reducing the energy consumption inside the device and ensuring the device's continuous working ability.

[0048] According to Figures 1-3 As shown in Figures 1-3 , two first rectangular grooves 501 are respectively provided on both sides of the inner wall of the upper box body 4. Outer grooves 13 are provided on both sides of the outer wall of one of the two outer edges 7. Handrails 14 are welded inside the two outer grooves 13 to determine the connection relationship between the first rectangular groove 501 and the overall device. The handrails 14 are provided for the lifting process of the upper housing 2 and the upper box body 4. The operator can firmly hold the handrails 14 to ensure the sufficiency of the externally applied force and reduce the difficulty of opening the upper housing 2 and the upper box body 4.

[0049] The effect achieved by the entire mechanism is as follows: When the box is working, according to the internal capacity of the lower box body 3 and the upper box body 4, a specified amount of cash is loaded. After completion, the upper housing 2 and the upper box body 4 are covered on the top of the lower housing 1. At this time, each trapezoidal lock tongue 11 spontaneously inserts into the lock grooves 12 to complete the preliminary locking of the box.

[0050] When the box is transported to the designated area and legally opened, the operator inserts the external key 9 horizontally into the lock core hole 8. The trapezoidal lock tongue 11 inputs the fingerprint of this person. After being authorized by the movable box system, the first layer of protection is removed. At the same time, the electromagnetic plate 602 in the assembly groove 601 is in an energized state, and the magnetic force generated on its surface fully adsorbs the metal plate 606 to ensure that the upper box body 4 is temporarily fixed to the upper housing 2. Hold the handrails 14 with both hands and pull forcefully until the upper housing 2 and the upper box body 4 are completely separated from the lower housing 1, and then the cash stored in the lower box body 3 can be taken out.

[0051] When the box body is illegally opened and a tool is used to pry the lower housing 1 and the upper housing 2, a large vibration will be generated, which will gradually exceed the constant value of the vibration sensor 603. At this time, the signal of its internal movement will be quickly fed back to the electromagnetic plate 602 and the active locking mechanism 5. The former is in a power-off state. At this time, the metal plate 606 loses the adsorption of the magnetic force on the surface of the electromagnetic plate 602, so the upper box body 4 can completely break away from the top of the inner wall of the upper housing 2, while the latter opens the second layer of protection. The process is as follows: the pneumatic push rod 503 in the transverse connecting plate 502 is opened, and the alloy insertion rod 504 and the limit retaining buckle 505 installed thereon are quickly longitudinally inserted into the internal part of the matching hole 507. At the same time, the positive and negative drive motor 510 in the positioning sleeve 509 is started and acts on the transmission rod 511, driving the driving gear 512 to rotate counterclockwise. By using the meshing connection between the driving gear 512 and the row of teeth 519, the distance between the row of teeth 519 and the support frame 515 is gradually reduced, and the thrust generated by the row of teeth 519 is fed back to the support frame 515 by the force receiving rod 522. At this time, by using the movable connection between the assembly rod 513 and the linkage gear 514 and the meshing connection between every two linkage gears 514, every two support frames 515 show a retracting trend, and the arc-shaped sleeve 516 installed thereon gradually comes into full contact with the surface of the alloy insertion rod 504. When the two are in full contact, the top of each limit retaining buckle 505 contacts the bottom of the arc-shaped sleeve 516, thus realizing the locking of the upper box body 4 and making it tightly cover the top of the upper box body 4.

[0052] At the same time, the tracker 524 in the second rectangular groove 523 will quickly lock the stability of the box body by satellite positioning, and the obtained signal will be quickly fed back into the monitoring terminal.

[0053] Although the present invention has been described in detail with reference to the foregoing embodiments, those skilled in the art can still modify the technical solutions described in the foregoing embodiments, or perform equivalent replacements for some of the technical features. Any modifications, equivalent replacements, improvements, etc. made within the spirit and principle of the present invention shall be included within the protection scope of the present invention.
