Description

Technical Field

[0001] This invention belongs to the field of financial storage box technology, specifically relating to a box handle that can be automatically detached. Background Technology

[0002] As the core equipment for cash storage and transportation, the anti-theft and self-destruct function of cash boxes is crucial to ensuring the safety of funds. Among them, the melting and unbinding of bundles of banknotes, the concealed locking of the external structure, and the prevention of illegal interference are the core prerequisites for the execution of the self-destruct procedure. Existing cash boxes usually adopt a fixed handle design, which can ensure the convenience of daily handling. However, the handle is mostly a fixed structure and cannot automatically detach to prevent the cash box from being illegally transferred. Moreover, the melting and dyeing operation requires opening the box door for manual operation, which is cumbersome and complicated. Therefore, it is necessary to design a box handle that can be automatically detached. Summary of the Invention

[0003] The purpose of this invention is to provide a simple and reasonably designed box handle that can be automatically detached in order to solve the above problems.

[0004] The present invention achieves the above objectives through the following technical solutions: An automatically detachable case handle includes an external handle fixed to a mounting plate, which abuts against an external support. The external support is equipped with a magnetic release mechanism and a self-closing mechanism. The external support is fixed to an internal support, which is equipped with a pop-out fusible mechanism. The internal and external supports are fixed at both ends inside the case. The pop-out fusible mechanism includes a support plate fixed to the internal support. Insulating posts are slidably connected in grooves on the support plate. Thermoelectric wires are arranged between the insulating posts, connecting to a power supply and control drive module. The power supply and control drive module is fixed to the internal support, and the insulating posts are connected to the pop-out drive mechanism.

[0005] As a further optimization of the present invention, the pop-out drive mechanism includes a drive motor fixed on the inner support, the output end of the drive motor is fixedly connected to one end of the lead screw, the other end of the lead screw is rotatably connected to the outer support, and a drive frame is provided on the lead screw.

[0006] As a further optimization of the present invention, the drive frame is provided with a connecting block, and the connecting block is slidably connected in the through groove opened in the inner support and the support plate, and the insulating column is fixed on the connecting block.

[0007] As a further optimization of the present invention, the magnetic release mechanism includes a locking frame disposed on an outer support, an adjusting block being slidably connected in a slide rail evenly provided on the locking frame, the adjusting block being threadedly connected to an adjusting stud, and the adjusting stud being rotatably connected to the locking frame.

[0008] As a further optimization of the present invention, a magnetic shielding plate is embedded in the locking frame, the magnetic shielding plate is located between adjacent adjusting blocks, a coil bracket is fixed on the top of the adjusting block, an electromagnetic coil is provided in the coil bracket, and the electromagnetic coil is connected to the power supply and control drive module.

[0009] As a further optimization of the present invention, one side of the adjusting block is connected to a locking ball via a guide rod. The locking ball is slidably connected in a locking groove opened in the sliding frame. A tripping groove is opened on the side wall of the sliding frame, and the tripping groove and the locking groove are interconnected. An unlocking magnetic block is embedded in the side of the sliding frame near the coil support.

[0010] As a further optimization of the present invention, a protrusion is provided on the side wall of the locking groove at the position corresponding to the tripping groove. The protrusion can detach and abut against the tripping contact. The tripping contact is provided on the locking ball and is connected to the power supply and control drive module.

[0011] As a further optimization of the present invention, the sliding frame is slidably connected to the docking inclined block, the docking inclined block is fixed on the mounting plate, and the docking inclined block is slidably connected to the inclined slide rail opened in the outer support.

[0012] As a further optimization of the present invention, the self-closing mechanism includes a closing plate slidably connected to the outer support, an installation block is fixed in a groove opened on the side of the outer support near the inner support, a closing lock head is slidably connected in the installation block, a support spring is provided between the closing lock head and the installation block, and one end of the closing lock head abuts against the closing plate, and the bottom of the closing plate abuts against the top of the docking inclined block.

[0013] The beneficial effects of this invention are as follows: 1. After the self-destruct program of this invention is triggered, the drive motor of the pop-up fuse mechanism drives the lead screw to rotate, and drives the insulating column to pop out synchronously through the drive frame and connecting block, so that the obliquely tensioned hot fuse wire accurately contacts the banknote binding strip. At the same time, the hot fuse wire is energized and heats up quickly, achieving rapid melting without residue adhesion, so that the bundle of banknotes is completely untied, clearing the way for the subsequent contamination material to evenly cover each banknote, ensuring the thoroughness of the self-destruction contamination effect. The banknote binding strip can be melted without opening the sealed door of the box, which is simple and convenient, and at the same time improves the safety of operation.

[0014] 2. After the self-destruct is triggered, the power supply and control drive module of this invention is powered by an electromagnetic coil. The magnetic field generated by the coil attracts the unlocking magnetic block on the sliding frame, causing the sliding frame to move upward so that the locking ball is aligned with the release slot. The docking wedge and the mounting plate fall down along the inclined slide under the action of gravity, realizing the automatic release of the handle without manual intervention, which is suitable for the automation requirements of emergency self-destruction.

[0015] 3. After the handle of this invention is disengaged from the docking inclined block, the support for the sealing plate is released. Under the action of gravity, the sealing plate moves down along the outer support groove and completely covers the inclined slide. At this time, the support spring pushes the sealing lock head to extend, restricting the sealing plate from moving up to achieve one-way locking. This completely blocks the channel for external interference with the internal fuse mechanism, power supply module and other core components through the slide, further ensuring the structural safety of the self-destruction process of the cash box.

[0018] The present application will now be described in further detail with reference to the accompanying drawings. It should be noted that the following specific embodiments are only used to further illustrate the present application and should not be construed as limiting the scope of protection of the present application. Those skilled in the art can make some non-essential improvements and adjustments to the present application based on the above application content.

[0019] Example: Please refer to Figure 1-10 A self-detachable case handle includes an outer handle 1, which is fixed to a mounting plate 2. The mounting plate 2 abuts against an outer support 4, which is fixed to an inner support 6. The inner support 6 and the outer support 4 are symmetrically fixed at both ends inside a case 8, with the outer support 4 located on the outermost side to support the mounting plate 2 and the outer handle 1. A magnetic release mechanism 3 is provided on the outer support 4, which is connected to the mounting plate 2. During daily use, the mounting plate 2 and the outer handle 1 can be fixed to both sides of the case 8. A pop-out fuse mechanism 7 is provided on the inner support 6. In normal operation, the mounting plate 2 is magnetically attached to the inner support 6, thereby locking the outer handle 1. When the case self-destructs, the outer handle 1 is released. The mounting plate 2 is fixed in place. In daily use, the external handle 1 provides a gripping point for the storage box 8, making it easy to carry or move the cash box. At the same time, the external handle 1 and the mounting plate 2 serve as external decoration and protective structures, concealing the internal structure and providing a hidden installation method for the internal structure, ensuring the concealment of the internal structure and preventing illegal damage. The storage box 8 is the core space for storing banknotes. One side is rotatably connected to a sealed door with a password, which can seal and hold bundles of banknotes. The sealed door works in conjunction with the anti-theft seal to achieve the anti-theft seal. At the same time, it provides a mounting carrier for the external support 4, the internal support 6 and the pop-out fuse mechanism 7. The pop-out fuse mechanism 7 is used to melt and cut the binding straps of the banknotes, so that the binding straps on the banknotes can be automatically untied without opening the sealed door, which is convenient for subsequent dyeing of the banknotes.

[0020] Please see Figure 2 and Figure 4-9 The magnetic release mechanism 3 includes a locking frame 31 fixed on the outer support 4. Adjusting blocks 32 are slidably connected in the evenly spaced slides on the locking frame 31. The adjusting blocks 32 are threadedly connected to the adjusting studs 33, and the two ends of the adjusting studs 33 are rotatably connected to the locking frame 31 through bearings. Magnetic shielding plates 34 are embedded in the evenly spaced grooves on the locking frame 31. The magnetic shielding plates 34 can isolate the magnetic field and are located between adjacent adjusting blocks 32. A coil bracket 35 is fixed to the top of the adjusting block 32 by screws. An electromagnetic coil 36 is wound on the iron core fixed in the coil bracket 35. The electromagnetic coil 36 is connected to the power supply and control drive module 9. The power supply and control drive module 9 is fixed on the inner support 6. One side of the adjusting block 32 is connected to the locking ball 37 via a guide rod. The locking ball 37 is slidably connected in the locking groove 39 of the sliding frame 38. The adjusting stud 33 is threadedly connected to the adjusting block 32, allowing adjustment of the height of multiple adjusting blocks 32 and the locking ball 37. The sliding frame 38 has a slot for the guide rod to pass through. The side wall of the sliding frame 38 has a tripping groove 40, which communicates with the locking groove 39. The tripping groove 40 allows the locking ball 37 to disengage from the locking groove 39 on the sliding frame 38 along an inclined direction. An unlocking magnet 41 is embedded in the side of the sliding frame 38 near the coil support 35. A protrusion 42 is provided on the side wall of the locking groove 39 at the position corresponding to the tripping groove 40. The protrusion 42 can disengage and abut against the tripping contact. 43. Tripping contacts 43 are located on locking balls 37 and are connected to the power supply and control drive module 9. When all tripping contacts 43 are abutted by protrusions 42, the power supply and control drive module 9 will issue a fuse command. The groove size of locking slot 39 is adapted to locking balls 37 to ensure that locking balls 37 are not loose or displaced after being embedded in normal conditions, thus avoiding accidental tripping. Sliding bracket 38 is slidably connected in grooves evenly opened on one side of mating inclined block 44. The mating inclined block 44 is fixed on mounting plate 2 and slidably connected in the inclined slide 45 opened in the outer support 4. In normal use, all locking balls 37 are slidably connected in locking slots 39, and under the action of gravity, sliding bracket 38 is positioned... At the bottom of the docking ramp 44, the locking ball 37 is positioned opposite the tripping groove 40, and the locking ball 37 is located above the tripping groove 40. Therefore, multiple locking balls 37 work together to fix the docking ramp 44 and the mounting plate 2, preventing them from disengaging. When the handle needs to be disengaged or the fuse needs to be cut off, the power supply and control drive module 9 first supplies power to the electromagnetic coil 36. The magnetic field generated by the energized electromagnetic coil 36 attracts the unlocking magnetic block 41 on the sliding frame 38 and drives the sliding frame 38 to move upward. The magnetic shielding plate 34 can use its magnetic shielding properties to isolate the superposition interference of the magnetic fields of adjacent electromagnetic coils 36 after they are energized, and at the same time block the influence of external magnetic fields on the working state of the internal coils, ensuring that the magnetic field strength generated by each electromagnetic coil 36 is stable and avoiding multi-coil interconnection. When in motion, magnetic field interference can cause insufficient suction or erratic movement; at the same time, it prevents external magnetic tools from interfering with the daily locking state, ensuring the reliability of daily use and preventing unauthorized interference. The sliding frame 38 moves upward until the unlocking magnet 41 corresponds to the position of the coil bracket 35. At this time, multiple locking balls 37 are simultaneously located at the release groove 40 position on the corresponding sliding frame 38. Under the action of gravity, the docking wedge 44 and the mounting plate 2 fall along the inclined slide 45. The locking balls 37 pass through the release groove 40 to release the fixation of the sliding frame 38, and automatically complete the process of disengaging the external handle 1. The positions of multiple locking balls 37 and electromagnetic coil 36 can be adjusted by rotating the adjusting stud 33 to form different combinations of staggered distribution, which improves the safety of the device.When the locking ball 37 aligns with the tripping slot 40, the tripping contact 43 abuts against the protrusion 42 and sends a signal to the power supply and control drive module 9, providing feedback on the alignment status of the locking ball 37 and the tripping slot 40. When all tripping contacts 43 are triggered, the power supply and control drive module 9 sends a fuse command to the pop-up fuse mechanism 7.

[0021] Please see Figure 3 and Figure 6 The outer support 4 is equipped with a self-closing mechanism 5. After the outer handle 1 and mounting plate 2 disengage, the self-closing mechanism 5 closes the inclined slide 45 on the outer support 4. The self-closing mechanism 5 includes a closing plate 51 slidably connected to the outer support 4. During normal use, the bottom of the closing plate 51 abuts against the top of the connecting inclined block 44. A mounting block 52 is fixed in a groove on the side of the outer support 4 near the inner support 6. A closing lock head 53 is slidably connected to the mounting block 52. A support spring 54 is provided between the closing lock head 53 and the mounting block 52, and the sealing... Under the elastic force of the support spring 54, the locking head 53 abuts against the closing plate 51. After the external handle 1 follows the docking inclined block 44 and disengages, the closing plate 51 moves down along the groove in the outer support 4 under the action of gravity until the inclined slide 45 is completely closed. At this time, the side wall of the closing plate 51 disengages from the locking head 53. Under the action of the support spring 54, the locking head 53 extends to restrict the upward movement of the closing plate 51, blocking the external intervention channel. It works with the locking head 53 to achieve one-way locking and prevent the closing plate 51 from accidentally moving upward and causing the slide to reopen.

[0022] Please see Figure 2-3 , Figure 6 , Figure 8 and Figure 10The pop-out fuse mechanism 7 includes a support plate 71 fixed to the inner support 6. Two insulating posts 72 are slidably connected in grooves on the support plate 71, and a tensioned hot fuse 73 is fixed between the two posts. The tensioned hot fuse 73, supported by the insulating posts 72, is obliquely distributed on both sides of the inner side of the housing. The hot fuse 73 is connected to a power supply and control drive module 9 via wires. The insulating posts 72 are connected to the pop-out drive mechanism 74. The support plate 71 precisely limits the sliding path of the insulating posts 72, ensuring that the two insulating posts 72 move synchronously, maintaining the tension of the hot fuse 73, and improving fuse stability. The pop-out drive mechanism 74... The system includes a drive motor 741 fixed to the inner support 6. The output end of the drive motor 741 is fixedly connected to one end of a lead screw 742, and the other end of the lead screw 742 is rotatably connected to the outer support 4 via a bearing. A drive frame 743 is mounted on the lead screw 742, and the drive frame 743 is connected to the lead screw 742 via a ball nut. Connecting blocks 744 are fixed at both ends of the drive frame 743, and the connecting blocks 744 are slidably connected in through slots opened on the inner support 6 and the support plate 71. An insulating column 72 is fixed to the connecting blocks 744. When the self-destruct program of the cash box is triggered, the power supply and control drive module 9 first supplies power to the electromagnetic coil 36, causing the external handle 1 to disengage, and all tripping mechanisms are activated. The synchronization signal from contact 43 is fed back to the power supply and control drive module 9, which then performs a fuse-breaking operation. The power supply and control drive module 9 outputs a start signal to the drive motor 741. Upon receiving the command, the drive motor 741 starts and outputs rotational power, driving the lead screw 742, which is fixedly connected to it, to rotate synchronously. Through the cooperating drive frame 743, the rotational motion is converted into the linear ejection motion of the drive frame 743. The drive frame 743 moves along the axis of the lead screw 742 toward the bundled banknotes inside the banknote box. The connecting blocks 744 at both ends of the drive frame 743 move synchronously. Under the driving force of the connecting blocks 744, the insulating column 72 smoothly ejects along the groove of the support plate 71. The edge post 72 moves synchronously, maintaining the tension of the hot fuse 73 until it makes full contact with the banknote binding strap. The power supply and control drive module 9 outputs an appropriate current to the hot fuse 73. After being energized, the hot fuse 73 heats up rapidly, reaching the temperature to melt the banknote binding strap. The energized hot fuse 73 acts directly on the banknote binding strap through high temperature. Because the hot fuse 73 is obliquely distributed, it can simultaneously contact the key stress points of the banknote binding strap, achieving rapid melting and a clean cut without residual adhesion, ensuring that the banknote binding strap is completely broken. After the banknote binding strap melts, the power supply and control drive module 9 cuts off the power supply to the hot fuse 73. The hot fuse 73 cools down after being de-energized, preventing continuous high temperature from affecting the internal environment of the banknote box or damaging the banknotes.

[0023] It should be noted that, in the normal standby state, the external handle 1 of this automatically detachable cabinet handle is locked by the mounting plate 2, the docking wedge 44 and the magnetic release mechanism 3. Multiple locking balls 37 are embedded in the locking grooves 39 of the sliding frame 38, and the mounting plate 2 is reliably fixed by gravity. The external handle 1 and the mounting plate 2 cover the internal release and fuse mechanism, ensuring the concealment of daily use and preventing illegal damage. After the self-destruct sequence of the cash box is triggered, the power supply and control drive module 9 supplies power to the electromagnetic coil 36 of the magnetic release mechanism 3. The electromagnetic coil 36 generates a directional magnetic field, which attracts the unlocking magnetic block 41 on the sliding frame 38. The attraction force causes the sliding frame 38 to move upward along the groove of the docking inclined block 44 until the unlocking magnetic block 41 is aligned with the coil support 35. At this time, multiple locking balls 37 are simultaneously aligned with the release groove 40 of the sliding frame 38. Under the action of gravity, the docking inclined block 44 and the mounting plate 2 fall along the inclined slide 45 of the outer support 4. The locking balls 37 are released from the lock through the release groove 40, and the external handle 1 automatically disengages with the mounting plate 2. At the same time, all the release contacts 43 on the locking balls 37 abut against the protrusions 42 of the locking groove 39, and send a release completion signal to the power supply and control drive module 9. After the external handle 1 disengages from the docking inclined block 44, the support for the sealing plate 51 is released. Under the action of gravity, the sealing plate 51 moves down along the groove of the outer support 4. When the sealing plate 51 moves down to completely cover the inclined slide 45, its side wall disengages from the sealing lock head 53. The support spring 54 releases its elastic force to push the sealing lock head 53 out and abut against the bottom of the sealing plate 51 to restrict its upward movement, thereby realizing the one-way locking and sealing of the slide and blocking the external channel to interfere with the internal mechanism through the slide. After receiving the tripping completion signal, the power supply and control drive module 9 sends a fuse command to the pop-up fuse mechanism 7. First, it outputs a start signal to the drive motor 741, which drives the lead screw 742 to rotate. Through the cooperation of the ball nut and the drive frame 743, the rotational motion is converted into the linear pop-out motion of the drive frame 743. The drive frame 743 drives the insulating column 72 to pop out smoothly along the groove of the support plate 71 through the connecting block 744. The two insulating columns 72 move synchronously to maintain the tension of the hot fuse 73. The obliquely distributed hot fuse 73 accurately approaches and contacts the bundle of banknotes. The power supply and control drive module 9 outputs an appropriate current to the hot fuse 73. The hot fuse 73 heats up quickly to the fuse temperature. The tensioned hot fuse 73 acts on the key stress point of the bundle of banknotes through high temperature, achieving fast and flat fuse breaking without residual adhesion, ensuring that the bundle of banknotes is completely broken. After the fuse breaking is completed, the power supply and control drive module 9 cuts off the power supply to the hot fuse 73, and the hot fuse 73 cools down to avoid damaging the banknotes or the internal environment of the banknote box.

[0024] The embodiments described above are merely examples of several implementations of the present invention, and while the descriptions are specific and detailed, they should not be construed as limiting the scope of the present invention. It should be noted that those skilled in the art can make various modifications and improvements without departing from the concept of the present invention, and these modifications and improvements all fall within the scope of protection of the present invention.
