Description

Technical Field

[0001] The present invention relates to the field of padlock equipment, and in particular to a safe intelligent padlock and a working method thereof. Background Art

[0002] A padlock is a portable lock that locks the lock by mechanically engaging the lock tongue and the lock beam inside the lock body. Its core components include the lock body and the U-shaped metal lock beam. Currently, common padlocks support opening with keys, passwords or biometrics. According to their functions, they are divided into mechanical locks, electronic locks and smart locks. Smart locks can achieve network control and remote management, but smart padlocks still use the structure of traditional mechanical padlocks. Its lock beam is connected to the top side of the lock body in an inverted U shape, and a U-shaped space is formed between the lock beam and the lock body to accommodate the lock buckle (also called the lock nose). Since the U-shaped space is easily penetrated by hard objects such as pry bars, the padlock is extremely easy to be pried open, which in turn leads to low padlock security. In order to improve the anti-pry performance of padlocks on the market, many methods are adopted to improve the structural strength of the lock tongue and lock beam, increase the number of lock beams, and set alarm functions. However, this type of padlock still does not solve the disadvantage that the lock beam is easy to penetrate into the pry bar and other demolition tools, and has not fundamentally changed the problem that this type of padlock structure is easy to pry open. Summary of the invention

[0003] The purpose of the present invention is to provide a safe smart padlock and a working method thereof in order to solve the above-mentioned problems. By adopting a hidden design in which the lock beam is stored between the panel and the shell when closed, the traditional U-shaped opening is eliminated to resist damage from a pry bar. At the same time, a dual locking mechanism of a mechanical lock tongue and a flexible steel cable is adopted to achieve hard lock protection and long-distance binding functions, as described below for details.

[0004] To achieve the above object, the present invention provides the following technical solutions:

[0005] A safety smart padlock provided by the present invention comprises a panel and a shell which fit each other, the shell being a U-shaped structure, an inverted U-shaped lock beam which passes through the shell being arranged on the outside of the panel, a receiving groove for receiving the lock beam which passes through the padlock buckle being formed between the middle of the shell and the panel, a positioning cylinder and a guide cylinder being arranged transversely inside the shell, a lock sleeve with adjustable vertical position being arranged inside the positioning cylinder, the lock sleeve being used to lock one end of the lock beam, the other end of the lock beam passing through the guide cylinder, a steel cable passing through the inside of the lock beam, one end of the steel cable being detachably connected to one end of the lock beam which extends into the positioning cylinder, and a winding component for winding and fixing the other end of the steel cable being arranged on the outside of the guide cylinder;

[0006] One end of the lock beam extending into the positioning cylinder is provided with a lock groove that is snap-fitted with the lock sleeve. The other end of the lock beam is provided with an auxiliary hole. On the top side of the guiding cylinder, there is a ejecting spring that extends into the auxiliary hole to keep the lock beam tightly pushed upward. At the top opening of the auxiliary hole, there is a wire threading hole for accommodating the steel cable to extend along the length of the lock beam. On the top side of the lock beam, there is a top groove that communicates with the wire threading hole to guide the steel cable to unfold outward.

[0007] Preferably, a limiting groove horizontally penetrates through the middle section of the lock beam above the lock groove. The limiting groove communicates with the top groove. And a limiting block that is snap-fitted into the limiting groove is fixed to the outer end of the steel cable. The limiting block is used to lock the outer end of the steel cable inside the positioning cylinder.

[0008] Preferably, a wire guiding seat for accommodating the steel cable to penetrate through is fixed to the bottom side of the guiding cylinder. The bottom end of the ejecting spring abuts against the top side of the wire guiding seat. Horizontally fixed to the outer part of the middle section of the guiding cylinder is a supporting suspension ear for supporting the winding and unwinding assembly. The winding and unwinding assembly includes a core shaft fixed to the bottom side of the supporting suspension ear. A winding drum is coaxially sleeved outside the core shaft. One end of the steel cable away from the limiting block is fixed to the outside of the winding drum. And a winding spring for supporting the winding drum to tightly wind and unwind the steel cable is arranged between the winding drum and the core shaft.

[0009] Preferably, two groups of shoulder grooves for accommodating the lock beam are horizontally symmetrically arranged on both sides of the top of the outer shell. And a bottom plate for supporting the positioning cylinder and the guiding cylinder is fixed to the bottom side of the outer shell. The bottom end of the positioning cylinder is a vertical through port. And an adjusting hole corresponding to the positioning cylinder is penetrated through the bottom plate. A vertically extending constraint groove is penetrated through the side of the positioning cylinder. And an internal thread is arranged on the inner wall of the positioning cylinder.

[0010] Preferably, the lock sleeve is an annular structure with a clearance fit with the inner wall of the positioning cylinder. A side groove horizontally penetrates through the middle section of the lock sleeve. Inside the side groove, a lock tongue that is snap-fitted with the lock groove at the end of the lock beam is horizontally slidably arranged. A supporting seat that horizontally penetrates through the constraint groove is fixed to the lock sleeve outside the side groove. The supporting seat is vertically slidably matched with the constraint groove. A support rod fixedly connected to the lock tongue horizontally penetrates through the middle of the supporting seat. And a spring for keeping the lock tongue abutted against the lock groove is sleeved outside the support rod.

[0011] Preferably, a box-shaped transmission frame extending longitudinally is fixed to the outer end of the support rod. An actuating assembly for pulling the lock tongue to move horizontally is arranged outside the supporting seat. The actuating assembly includes a reduction motor fixed to the outside of the supporting seat. The output end of the reduction motor is fixed with a swing arm with a cam structure. A transmission rod vertically extending into the transmission frame is fixed at the eccentric position at the top end of the swing arm. The transmission rod rotates following the swing arm to pull the transmission frame to move horizontally, thereby driving the support rod and the lock tongue to perform the unlocking action.

[0012] Preferably, a rotating ring is coaxially fixed to the bottom end of the lock sleeve. A base ring is sleeved outside the rotating ring. A rotating groove for rotatably mating with the rotating ring is provided along the inner edge of the top end of the base ring. An external thread adapted to the internal thread on the inner wall of the positioning cylinder is provided on the outer circumferential side of the base ring. A regular polygon adjusting groove is provided on the inner side of the bottom end of the base ring, and the end of the lock beam passes downward through the adjusting groove.

[0013] Preferably, two fixing plates extending longitudinally into the interior of the housing are fixed to the rear side of the panel. An installation hole for accommodating the positioning cylinder and the guiding cylinder is vertically penetrated through the middle of the fixing plate. Screw holes are provided on the fixing plates outside the two installation holes. Two connecting ears extending longitudinally below the screw holes are fixed to the inner side of the housing. Fixing screws for threadedly fixing the connecting ears are vertically inserted into the two screw holes. A sliding groove is vertically penetrated through one of the fixing plates above the lock sleeve. A sliding seat for covering the top surface of the fixing screw is horizontally slidably arranged in the sliding groove.

[0014] Preferably, the positioning cylinder and the guiding cylinder are in interference fit with the installation holes of the two fixing plates respectively. The fixing plate and the panel are both made of zinc alloy and integrally formed. A control system integrating a fingerprint module and a password module is provided in the middle of the panel. The control system is electrically connected to the reduction motor.

[0015] The working method of the safety intelligent padlock includes the following steps:

[0016] a. When locking the padlock latch, the reduction motor drives the swing arm and the transmission rod to rotate. The eccentrically installed transmission rod rotates to drive the transmission frame and the support rod to slide horizontally. The support rod pulls the lock tongue out of the lock groove of the lock beam along the side groove, so as to release the locked state of the end of the lock beam in the lock sleeve. At this time, the ejecting spring in the compressed state pushes the lock beam upward to move it upward, so that one end of the lock groove of the lock beam disengages from the shoulder groove opening of the housing to complete the unlocking action. Then, one end of the lock groove of the lock beam passes through the padlock latch to be locked, and the lock beam is pressed to make the end lock groove press back into the lock sleeve. The spring pushes the wedge-shaped lock tongue to be clamped into the lock groove again to complete the locking action of the padlock latch;

[0017] b. By retracting the locking beam and the lock catch into the receiving groove between the panel and the housing to hide the locking beam in the locked state, the problem that the locking beam is easily penetrated by a crowbar and pried open violently is solved. When it is necessary to restore the locked state of the locking beam to the structural form of a traditional padlock, the padlock is opened to ensure that one end of the locking groove of the locking beam disengages from the lock sleeve, and the occupancy state of the adjusting groove by the end of the locking beam is released. At this time, the adjusting groove is exposed. An external polygon wrench corresponding to the shape of the adjusting groove is inserted into the positioning cylinder along the adjusting hole of the housing to ensure that the wrench is stuck in the adjusting groove. Then, the wrench is rotated to drive the base ring to rotate. By the threaded engagement between the base ring and the inner wall of the positioning cylinder, the lock sleeve is driven to drive the actuating assembly to slide vertically along the restraining groove, so as to correspondingly adjust the vertical position of the lock sleeve and adaptively adjust the height position of the locking beam extending into the housing. Only when the locking beam is in the unlocked state and the end of the locking beam disengages from the lock sleeve can the height positions of the lock sleeve and the actuating mechanism be adjusted to ensure the structural stability of the lock body in the hidden state of the locking beam;

[0018] c. When it is necessary to pull the steel cable to lock a long-distance object, the locking beam is unlocked by the actuating assembly. After one end of the locking groove of the locking beam disengages from the housing, the limiting block at the end of the steel cable is laterally pushed out of the limiting groove of the locking beam to expose the free end of the steel cable. At this time, the steel cable is pulled outwards, and the wound part of the steel cable outside the unwinding drum is unwound to pull the end of the steel cable out along the top groove of the locking beam. Then, the steel cable is passed through the object to be locked, and the limiting block at the free end of the steel cable is laterally snapped into the limiting groove of the locking beam again, and the locking beam is pressed back into the positioning cylinder inside the housing, and the lock sleeve is used to lock the locking beam to realize the synchronous locking action of the hard locking structure of the locking beam and the soft locking structure of the steel cable;

[0019] d. When it is necessary to remove the housing from the panel, the locking beam is unlocked so that one end of the locking groove of the locking beam is lifted out of the housing upwards to ensure that the end of the locking beam close to the sliding seat disengages from the mounting hole. At this time, the blocking effect of the locking beam on the lateral sliding of the sliding seat is released, so that the sliding seat above the fixing screw can be laterally pushed to the mounting hole position, thereby releasing the covering state of the sliding seat on the fixing screw. At this time, the operator unscrews the two groups of fixing screws to release the locking state of the fixing plate and the connecting ear, ensuring that the lock body can be disassembled only in the unlocked state.

[0020] The beneficial effects are as follows: 1. By providing a lock beam, a lock sleeve and an actuating assembly that can be adjusted in height, when the lock beam is closed, it is completely received in the receiving groove between the panel and the housing, and only the end of the lock beam is exposed in the shoulder groove at the top of the housing when unlocking, eliminating the exposed U-shaped opening of the traditional padlock. The crowbar cannot directly contact the locking beam, fundamentally solving the defect that the traditional padlock is easily damaged by tools inserted into the U-shaped space, and significantly improving the anti-prying performance;

[0021] 2. A double locking mechanism is set up. The lock sleeve is pushed by a spring to make the wedge-shaped lock tongue snap into the lock beam groove, providing high anti-pulling force. The lock beam is internally provided with a retractable steel cable, and the end limit block of the steel cable snaps into the lock beam limit groove to achieve long-distance flexible bundling and locking, breaking through the limitation of the fixed length of traditional padlocks;

[0022] 3. Through the threaded fit of the lock sleeve with the base ring and the positioning cylinder, the lock sleeve can drive the execution component to slide vertically along the constraint groove, changing the positioning height of the lock beam to adapt to lock buckles of different thicknesses. During specific operation, a polygon wrench is used to steplessly adjust the height of the lock beam through the adjustment hole and the adjustment groove, and it can only be operated when the lock beam is unlocked, ensuring that the position of the lock beam in the locked state is non-adjustable, improving the safety of use;

[0023] 4. An anti-disassembly sliding seat is set up to cover the fixing screws with the sliding seat. When the lock beam is unlocked, the sliding seat can slide horizontally to the position of the installation hole to expose the fixing screws, avoiding violent disassembly. Disassembly requires both the lock beam to be disengaged and the sliding seat to be moved away, preventing illegal disassembly;

[0024] 5. The hidden lock beam can also avoid handling collisions, reduce the swaying of the padlock during movement, and can use the steel cable to bind the goods to the shelf, improving the stability of use. BRIEF DESCRIPTION OF THE DRAWINGS

DETAILED DESCRIPTION

[0046] To make the purpose, technical solution and advantages of the present invention clearer, the technical solution of the present invention will be described in detail below. Obviously, the described embodiments are only part of the embodiments of the present invention, rather than all the embodiments. Based on the embodiments of the present invention, all other implementation methods obtained by ordinary technicians in this field without creative work belong to the scope of protection of the present invention.

[0047] See also Figures 1-18 As shown, the present invention provides a safe smart padlock, including a panel 1 and a shell 2 fitted to each other, the shell 2 is a U-shaped structure, the panel 1 and the shell 2 are both manufactured by a zinc alloy one-piece molding process, and are precisely fitted to each other to form a rigid frame structure, which can effectively enhance the overall stability and anti-destruction ability of the padlock in practical applications, an inverted U-shaped lock beam 4 passing through the shell 2 is provided on the outer side of the panel 1, and a receiving groove 3 (the lock buckle 12 is also called a lock nose, door nose, door buckle, door hasp, etc.) for accommodating the lock beam 4 to pass through the padlock buckle 12 is formed between the middle part of the shell 2 and the panel 1, when locked, the panel 1 faces outwards and the shell 2 faces the padlock buckle 12, thereby fundamentally eliminating the U-shaped opening exposed to the outside of the traditional padlock, and further improving the anti-pry performance. A positioning cylinder 5 and a guide cylinder 8 are arranged transversely inside the housing 2. A locking sleeve 6 with adjustable vertical position is arranged inside the positioning cylinder 5. The locking sleeve 6 is used to lock one end of the locking beam 4. The other end of the locking beam 4 passes through the guide cylinder 8. A steel cable 9 is passed through the locking beam 4. The steel cable 9 is made of a plurality of steel wires. One end of the steel cable 9 is detachably connected to the end of the locking beam 4 extending into the positioning cylinder 5. A winding assembly 10 for winding and fixing the other end of the steel cable 9 is arranged outside the guide cylinder 8.

[0048] One end of the lock beam 4 extending into the positioning cylinder 5 is provided with a lock groove 401 that is engaged and fitted with the lock sleeve 6. The lock groove 401 is designed with a 45° wedge-shaped groove. The other end of the lock beam 4 is provided with an auxiliary hole 402. On the top side of the guiding cylinder 8, there is a ejecting spring 802 that extends into the auxiliary hole 402 to keep the lock beam 4 tightly pushed upward. At the top opening of the auxiliary hole 402, there is a wire threading hole 403 for accommodating the steel cable 9 to extend along the length of the lock beam 4. On the top side of the lock beam 4, there is a top groove 404 that communicates with the wire threading hole 403 to guide the steel cable 9 to unfold outward, facilitating the outward extraction of the steel cable 9 from the lock beam 4 for flexible locking using the steel cable 9.

[0049] As an alternative implementation, in the middle section of the lock beam 4 above the lock groove 401, there is a limiting groove 405 that runs horizontally through. The limiting groove 405 communicates with the top groove 404. A limiting block 901 that is engaged and placed in the limiting groove 405 is fixed to the outer end of the steel cable 9. The limiting block 901 is used to lock the outer end of the steel cable 9 inside the positioning cylinder 5, allowing the limiting block 901 at the end of the steel cable 9 to be quickly engaged or disengaged. On the bottom side of the guiding cylinder 8, there is a lead seat 801 that accommodates the steel cable 9 to pass through. Inside the lead seat 801, there is a ceramic bushing for guiding the steel cable 9 to pass through, which can reduce the wear of the steel cable 9. The bottom end of the ejecting spring 802 abuts against the top side of the lead seat 801. Horizontally fixed to the outer side of the middle section of the guiding cylinder 8 is a supporting hanger ear 803 for supporting the winding and unwinding assembly 10. The winding and unwinding assembly 10 includes a core shaft 10a fixed to the bottom side of the supporting hanger ear 803. A winding drum 10b is coaxially sleeved on the outer side of the core shaft 10a. One end of the steel cable 9 away from the limiting block 901 is fixed to the outer side of the winding drum 10b. Between the winding drum 10b and the core shaft 10a, there is a winding spring 10c for supporting the winding drum 10b to tightly wind and unwind the steel cable 9, which can automatically maintain the pre-tension of the steel cable 9.

[0050] On both sides of the top of the outer shell 2, there are two groups of shoulder grooves 201 that are horizontally symmetrically arranged for accommodating the lock beam 4, facilitating the guiding of the lock beam 4 to extend out of the outer shell 2. On the bottom side of the outer shell 2, there is a bottom plate 202 for supporting the positioning cylinder 5 and the guiding cylinder 8. On the top side of the bottom plate 202, there is a supporting seat 204 for cooperating with the supporting hanger ear 803 to support the core shaft 10a. The bottom end of the positioning cylinder 5 is a vertical through-hole, and on the bottom plate 202, there is an adjustment hole 203 corresponding to the positioning cylinder 5. Vertically extending through the side of the positioning cylinder 5 is a constraint groove 501, and on the inner wall of the positioning cylinder 5, there is an internal thread 502. The lock sleeve 6 is a circular ring structure with a clearance fit to the inner wall of the positioning cylinder 5. Horizontally running through the middle section of the lock sleeve 6 is a side groove 601. Inside the side groove 601, there is a lock tongue 603 that is engaged and adapted to the lock groove 401 at the end of the lock beam 4 and slides horizontally. Fixed to the lock sleeve 6 outside the side groove 601 is a supporting seat 602 that horizontally passes through the constraint groove 501. The supporting seat 602 is vertically slidably engaged with the constraint groove 501. Horizontally running through the middle of the supporting seat 602 is a support rod 604 that is fixedly connected to the lock tongue 603. Outside the support rod 604, there is a spring 605 for keeping the lock tongue 603 tightly pressed into the lock groove 401.

[0051] A longitudinally extending square-shaped transmission frame 606 is fixed to the outer end of the support rod 604. An actuating assembly 7 for pulling the latch 603 to move horizontally is arranged outside the support base 602. The actuating assembly 7 includes a reduction motor 701 fixed to the outside of the support base 602. A swing arm 702 with a cam structure is fixed to the output end of the reduction motor 701. A transmission rod 703 vertically extending into the transmission frame 606 is fixed to the eccentric position at the top of the swing arm 702. The transmission rod 703 is in clearance fit with the transmission frame 606. The transmission rod 703 rotates with the swing arm 702 to pull the transmission frame 606 to move horizontally, thereby driving the support rod 604 and the latch 603 to perform the unlocking action. A rotating ring 607 is coaxially fixed to the bottom end of the lock sleeve 6. A base ring 608 is sleeved outside the rotating ring 607. A rotating groove 608a for rotatably mating with the rotating ring 607 is arranged along the inner edge at the top of the base ring 608. A number of steel balls are arranged in the rotating groove 608a to form a rolling friction pair, improving the rotational stability of the rotating connection position between the base ring 608 and the lock sleeve 6. An external thread 609 adapted to the internal thread 502 on the inner wall of the positioning cylinder 5 is arranged on the outer circumferential side of the base ring 608. A regular polygon-shaped adjustment groove 608b, preferably a regular hexagon, is arranged on the inner side at the bottom end of the base ring 608 to facilitate inserting an external hexagon wrench into the adjustment groove 608b to rotate the base ring 608. The end of the lock beam 4 passes downward through the adjustment groove 608b. When the lock beam 4 is in the locked state, it is ensured that the end of the lock beam 4 extends into the adjustment groove 608b to block the adjustment groove 608b, preventing the height position of the lock beam 4 from being adjusted when the lock beam 4 is in the locked state.

[0052] Two groups of fixing plates 101 longitudinally extending into the interior of the housing 2 are fixed to the rear side of the panel 1. An installation hole 102 for accommodating the positioning cylinder 5 and the guide cylinder 8 runs vertically through the middle of the fixing plate 101. Screw holes 103 are arranged on the fixing plates 101 outside the two groups of installation holes 102. Two groups of connecting ears 205 longitudinally extending below the screw holes 103 are fixed to the inner side of the housing 2. Fixing screws 104 for threadedly fixing the connecting ears 205 are vertically inserted into the two groups of screw holes 103. A chute 105 runs vertically through a fixing plate 101 above the lock sleeve 6. A sliding seat 11 for covering the top surface of the fixing screw 104 is horizontally slidably arranged in the chute 105. The positioning cylinder 5 and the guide cylinder 8 are in interference fit with the installation holes 102 of the two groups of fixing plates 101 respectively, improving the structural installation strength of the positioning cylinder 5 and the guide cylinder 8. Both the fixing plate 101 and the panel 1 are made of zinc alloy and integrally formed. A control system integrating a fingerprint module and a password module is arranged in the middle of the panel 1. The control system is electrically connected to the reduction motor 701. A rechargeable battery is arranged inside the housing 2 to supply power to the control system and the reduction motor 701.

[0053] The disclosed safe intelligent padlock optimizes the structure of the traditional padlock. The integrally formed panel 1 and the outer shell 2 form a firm and rigid frame structure, effectively optimizing the overall structure of the lock body and the lock beam 4, improving the overall stability and significantly enhancing the anti-destruction performance. For the safe intelligent padlock described in this application, the lock beam 4 is designed in an inverted U shape, and precise locking and hiding operations are achieved through internal mechanisms such as the positioning cylinder 5, the guiding cylinder 8, and the lock sleeve 6, effectively eliminating the defect that the traditional padlock is easily penetrated by hard tools such as pry bars due to the exposed U-shaped opening. At the same time, a multi-layer protection mechanism is set up, including the steel cable 9, the limit block 901, the winding assembly 10, and the ejecting spring 802 working together. Through the synchronous locking of the hard locking of the lock beam 4 and the soft locking of the steel cable 9, the tight combination between the lock catch 12 and the lock body is achieved, further ensuring that the lock body can still maintain a high level of security under various external forces. In addition, the safe intelligent padlock described in this application also integrates an identification control system of a fingerprint module and a password module. The reduction motor 701 drives the execution component 7 to complete the automatic pulling and precise control of the lock tongue 603, enabling the user to not only save the cumbersome traditional mechanical unlocking steps during operation but also greatly reduce the safety hazards caused by operation errors. Combining the mutual adjustment design of the lock sleeve 6 and the base ring 608, the flexible adaptation of the height position of the lock beam 4 is achieved, and the optimal anti-prying effect can be achieved whether in the concealed locking state of the padlock catch or in the traditional opening structure state.

[0054] This application also discloses a working method of a safe intelligent padlock, including the following steps:

[0055] a. When locking the padlock catch 12, the reduction motor 701 drives the swing arm 702 and the transmission rod 703 to rotate. The eccentrically installed transmission rod 703 rotates to drive the transmission frame 606 and the support rod 604 to slide horizontally. The support rod 604 pulls the lock tongue 603 to withdraw from the lock groove 401 of the lock beam 4 along the side groove 601, thus releasing the locked state of the end of the lock beam 4 in the lock sleeve 6. At this time, the compressed ejecting spring 802 pushes the lock beam 4 upward to move it up, so that one end of the lock groove 401 of the lock beam 4 disengages from the opening of the shoulder groove 201 of the outer shell 2 to complete the unlocking action (as Figure 17 shown). After that, one end of the lock groove 401 of the lock beam 4 passes through the padlock catch 12 to be locked, and the lock beam 4 is pressed so that its end lock groove 401 is pressed back into the lock sleeve 6. The spring 605 pushes the wedge-shaped lock tongue 603 to be clamped into the lock groove 401 again to complete the locking action of the padlock catch 12 (as Figure 14 、 15 shown);

[0056] b. By putting the lock beam 4 and the lock catch 12 into the accommodation groove 3 between the panel 1 and the outer shell 2, the lock beam 4 is hidden in the locked state (as Figure 1 、2 As shown in FIGS. 4 and 13, to solve the problem that the locking beam 4 is easily penetrated by a crowbar and violently pried open, when it is necessary to restore the locked state of the locking beam 4 to the structural form of a traditional padlock, the padlock is opened to ensure that one end of the locking groove 401 of the locking beam 4 is disengaged from the lock sleeve 6, and the occupancy state of the end of the locking beam 4 on the adjustment groove 608b is released. At this time, the adjustment groove 608b is exposed. An external polygonal wrench corresponding to the shape of the adjustment groove 608b is inserted into the positioning cylinder 5 along the adjustment hole 203 of the housing 2 to ensure that the wrench is stuck in the adjustment groove 608b. Then, the wrench is rotated to drive the base ring 608 to rotate. By the threaded cooperation between the base ring 608 and the inner wall of the positioning cylinder 5, the lock sleeve 6 is driven to drive the actuating assembly 7 to vertically slide along the constraint groove 501, so as to realize the corresponding adjustment of the vertical position of the lock sleeve 6 and adaptively adjust the height position of the locking beam 4 extending into the housing 2 (as Figure 18 shown). Only when the locking beam 4 is in the unlocked state and the end of the locking beam 4 is disengaged from the lock sleeve 6 can the height positions of the lock sleeve 6 and the actuator be adjusted to ensure the structural stability of the lock body when the locking beam 4 is in the hidden state;

[0057] c. When it is necessary to pull the steel cable 9 to lock a long-distance object, the locking beam 4 is unlocked through the actuating assembly 7 (as Figure 17 shown). After one end of the locking groove 401 of the locking beam 4 is disengaged from the housing 2, the limit block 901 at the end of the steel cable 9 is laterally pushed out from the limit groove 405 of the locking beam 4 to expose the free end of the steel cable 9. At this time, the steel cable 9 is pulled outwards, and the wound part of the steel cable 9 outside the unwinding reel 10b is unwound to pull the end of the steel cable 9 out along the top groove 404 of the locking beam 4 (as Figure 16 shown). Then, the steel cable 9 is passed through the object to be locked, and the limit block 901 at the free end of the steel cable 9 is laterally snapped into the limit groove 405 of the locking beam 4 again, and the locking beam 4 is pressed back into the positioning cylinder 5 inside the housing 2. The lock sleeve 6 is used to lock the locking beam 4, and the excess steel cable 9 can be wound around the outside of the locking beam 4 to ensure the tension state of the steel cable 9 on the locked object, so as to realize the synchronous locking action of the hard locking structure of the locking beam 4 and the soft locking structure of the steel cable 9 (as Figure 16 shown);

[0058] d. When it is necessary to remove the housing 2 from the panel 1, the locking beam 4 is unlocked so that one end of the locking groove 401 of the locking beam 4 is upwardly disengaged from the housing 2, ensuring that the end of the locking beam 4 near the sliding seat 11 is disengaged from the mounting hole 102. At this time, the blocking effect of the locking beam 4 on the lateral sliding of the sliding seat 11 is released, so that the sliding seat 11 above the fixing screw 104 can be laterally pushed to the position of the mounting hole 102, thereby releasing the covering state of the sliding seat 11 on the fixing screw 104. At this time, the operator unscrews the two groups of fixing screws 104 to release the locking state of the fixing plate 101 and the connecting ear 205, ensuring that the lock body can be disassembled only in the unlocked state.

[0059] In the present invention, a liftable and adjustable lock beam 4, a lock sleeve 6 and an actuating assembly 7 are provided. When the lock beam 4 is closed, it is completely received in the receiving groove 3 between the panel 1 and the outer shell 2. Only the end of the lock beam 4 is exposed in the shoulder groove 201 at the top of the outer shell 2 during unlocking, eliminating the exposed U-shaped opening of the traditional padlock. The crowbar cannot directly contact the lock beam 4, fundamentally solving the defect that the traditional padlock is easily damaged by tools inserted into the U-shaped space, and significantly improving the anti-prying performance;

[0060] A dual locking mechanism is set. The lock sleeve 6 pushes the wedge-shaped lock tongue 603 into the lock groove 401 of the lock beam 4 through the spring 605 to provide high anti-pulling force. A retractable steel cable 9 is built into the lock beam 4, and the limit block 901 at the end of the steel cable 9 is snapped into the limit groove 405 of the lock beam 4 to achieve long-distance flexible bundling and locking, breaking through the limitation of the fixed length of the traditional padlock;

[0061] The lock sleeve 6 can vertically slide along the constraint groove 501 together with the actuating assembly 7 through the threaded cooperation between the base ring 608 and the positioning cylinder 5, changing the positioning height of the lock beam 4 to adapt to different thicknesses of the lock catch 12. During specific operation, a polygon wrench is used to steplessly adjust the height of the lock beam 4 through the adjustment hole 203 and the adjustment groove 608b, and it can only be operated when the lock beam 4 is in the unlocked state, ensuring that the position of the lock beam 4 is non-adjustable in the locked state and improving the use safety;

[0062] An anti-disassembly sliding seat 11 is provided to cover the fixing screw 104 with the sliding seat 11. When the lock beam 4 is unlocked, the sliding seat 11 can horizontally slide to the position of the mounting hole 102 to expose the fixing screw 104, avoiding violent disassembly. Disassembly requires both the lock beam 4 to be removed and the sliding seat 11 to be moved away to prevent illegal disassembly;

[0063] The hidden lock beam 4 can also avoid handling collisions, reduce the shaking of the padlock during movement, and can use the steel cable 9 to bind the goods to the shelf, improving the use stability.

[0064] The above is only the specific implementation manner of the present invention, but the protection scope of the present invention is not limited thereto. Any person skilled in the art within the technical scope disclosed by the present invention can easily think of changes or substitutions, which should all be covered within the protection scope of the present invention. Therefore, the protection scope of the present invention should be subject to the protection scope of the claims.

When locking the padlock buckle (12), the reduction motor (701) drives the swing arm (702) and the transmission rod (703) to rotate, and the eccentrically mounted transmission rod (703) is rotated to drive the transmission frame (606) and the support rod (604) to slide laterally, and the support rod (604) is used to pull the lock tongue (603) along the side groove (601) to exit the lock groove (401) of the lock beam (4), thereby releasing the locking state of the end of the lock beam (4) in the lock sleeve (6). At this time, the ejection spring (606) in the compressed state is released. 802) presses the lock beam (4) upward to move it upward, so that one end of the lock groove (401) of the lock beam (4) is disengaged from the shoulder groove (201) opening of the housing (2), and the unlocking action is completed. Then, one end of the lock groove (401) of the lock beam (4) passes through the padlock buckle (12) to be locked, and the lock beam (4) is pressed to press the end lock groove (401) back into the lock sleeve (6). The spring (605) is used to push the wedge-shaped lock tongue (603) to be clamped into the lock groove (401) again, and the padlock buckle (12) is locked. b. The lock beam (4) and the lock buckle (12) are received in the receiving groove (3) between the panel (1) and the housing (2), so as to hide the lock beam (4) in the locked state, thereby solving the problem that the lock beam (4) is easily penetrated by a crowbar and violently pried open. If it is necessary to restore the locked state of the lock beam (4) to the structural form of a traditional padlock, the padlock is opened to ensure that one end of the lock groove (401) of the lock beam (4) is out of the lock sleeve (6), and the occupation state of the end of the lock beam (4) on the adjustment groove (608b) is released. At this time, the adjustment groove (608b) is exposed, and an outer polygonal wrench corresponding to the shape of the adjustment groove (608b) is used to extend into the adjustment hole (203) of the housing (2) to lock the lock beam (4). The locking sleeve (6) is locked in the locking tube (5) to ensure that the wrench is inserted into the adjusting groove (608b). The wrench is then rotated to drive the base ring (608) to rotate.
