Description

Technical Field

[0001] This invention relates to the field of locks, and in particular to a wire rope padlock. Background Technology

[0002] Locks are a frequently used safety tool in daily life and industrial production, encompassing many types, with traditional padlocks being the most common due to their simplicity and practicality. Padlocks are ubiquitous in both industrial safety and everyday life. However, some keyhole diameters are too small for traditional padlocks due to their larger hook diameters. Additionally, some objects need to be locked while simultaneously allowing for adjustment of the locking space to generate a certain preload. Currently, padlock hooks are rigid and cannot generate sufficient preload. Furthermore, existing locks are ineffective in situations where the locking distance is too large or too small, resulting in low flexibility. In these cases, wire rope padlocks, due to the flexibility of the rope, can be applied in more scenarios and meet these requirements.

[0003] Wire rope padlocks come in three types: padlock, telescopic, and combination lock. Padlock and combination lock types are similar to ordinary padlocks. Telescopic locks allow adjustment of the locking rope length and the preload on the locked object. Wire rope padlocks are flexible, making them suitable for confined spaces where ordinary padlocks are difficult to install directly. However, this can increase the space available for the locked object to move, resulting in slightly less effective locking. Telescopic wire rope locks overcome this drawback.

[0004] Currently, there are two types of retractable wire rope padlocks: one is a one-time use padlock that can be locked but not pulled back; the other uses an external button to unlock, requiring the user to manually press the unlock button while simultaneously pulling the rope outwards with the other hand. Summary of the Invention

[0051] Figure 1This is a cross-sectional schematic diagram of an embodiment of the wire rope padlock of the present invention. The wire rope padlock includes a housing support assembly 100, a locking rope 200, an unlocking / locking assembly 300, and a drive assembly 400.

[0052] Figure 2 This is an exploded perspective view of the housing support assembly in one embodiment of the wire rope padlock of the present invention. The view is intended to clearly show some of the internal structures of the housing support assembly. Figure 2 The partial cross-section of some components is shown. The housing support assembly 100 includes opposing first surfaces S1 and second surfaces S2, and the first surface S1 is provided with a first channel 111 extending in a first direction.

[0053] Figure 3 This is a perspective view of the locking rope in one embodiment of the wire rope padlock of the present invention. The locking rope 200 includes a fixed end 210 and a movable end 220. The fixed end 210 is fixedly installed on the first surface S1, and the movable end 220 can pass through the first channel 111.

[0054] Figure 4 This is an exploded perspective view of the locking / unlocking component in one embodiment of the wire rope padlock of the present invention. Figure 5 This is an exploded perspective view of the unlocking and locking assembly in one embodiment of the wire rope padlock of the present invention. The unlocking and locking assembly 300 is disposed on the housing support assembly 100 and communicates with the first channel 111. The unlocking and locking assembly 300 includes a sliding sleeve 310, a limiting member 320, and a clamping member CM. The sliding sleeve 310 is slidably disposed within the housing support assembly 100 along a first direction, and a limiting groove 311 is provided on the side wall of the sliding sleeve 310. The clamping member CM is movably disposed on the sliding sleeve 310, and the clamping member CM moves along the first direction to clamp or release the locking rope 200. The clamping surface of the clamping member CM is provided with a one-way guide strip 331. In this embodiment, the unidirectional guide bar 331 has a serrated structure. When the serrated unidirectional guide bar 331 of the clamping member CM clamps the locking rope 200, the locking rope 200 can move relative to the clamping member CM in one unidirectional direction when the locking rope 200 is pulled forcefully. When the locking rope 200 is pulled in the opposite direction, the locking rope 200 is locked to the clamping member CM. In this embodiment, the limiting member 320 is a limiting ball. In some other embodiments, the limiting member 320 can be a limiting member 320 of other shapes.

[0055] Figure 6 This is an exploded perspective view of the drive assembly in one embodiment of the wire rope padlock of the present invention. Figure 7 This is an exploded perspective view of the drive assembly in one embodiment of the wire rope padlock of the present invention. The drive assembly 400 is disposed within the housing support assembly 100, and the drive assembly 400 is used to cause the limiting member 320 to enter or exit the limiting groove 311.

[0056] The wire rope padlock has a normal state and an unlocked state.

[0057] In normal condition, the limiting member 320 enters the limiting groove 311 to limit the sliding sleeve 310. After the movable end 220 is inserted into the housing bracket assembly 100, the clamping member CM can clamp the locking rope 200. The one-way guide bar 331 allows the locking rope 200 to move in the direction of entering the first channel 111 and prevents the locking rope 200 from moving in the direction of exiting the first channel 111.

[0058] In the unlocked state, the limiting member 320 exits the limiting groove 311, and the sliding sleeve 310 can move along the first direction to allow the clamping member CM to release the locking rope 200, and the locking rope 200 can move in the direction of exiting the first channel 111.

[0059] According to an embodiment of the present invention, the wire rope padlock has a normal state and an unlocked state. In the normal state, the limiting member 320 enters the limiting groove 311 of the sliding sleeve 310 to limit the sliding sleeve 310. At this time, after the movable end 220 of the locking rope 200 passes into the housing support assembly 100, the clamping member CM can clamp the locking rope 200. The one-way guide bar 331 allows the locking rope 200 to move in the direction of entering the first channel 111 and prevents the locking rope 200 from moving in the direction of exiting the first channel 111. That is, the enclosing space between the locking rope 200 and the housing support assembly 100 can be further reduced, and the locking rope 200 will not be pulled out, thus realizing the normal locking function of the wire rope padlock containing the locking rope 200. In the unlocked state, the limiting member 320 exits the limiting groove 311, and the sliding sleeve 310 can move along the first direction, causing the clamping member CM to release the locking rope 200. The locking rope 200 can move in the direction of exiting the first channel 111, and the locking rope 200 can be pulled out to unlock the wire rope padlock. The wire rope padlock of this embodiment of the invention can realize the conventional locking function in the normal state and can also realize unlocking in the unlocked state, so that the wire rope padlock containing the locking rope 200 can be reused. According to the wire rope padlock of this embodiment of the invention, the driving component 400 is disposed in the housing support assembly 100 and can cause the limiting member 320 to enter or exit the limiting groove 311, so as to realize the switching between the normal state and the unlocked state of the wire rope padlock. The aforementioned wire rope padlock is unlocked via a drive assembly 400 housed within the housing support assembly 100. This eliminates the need for an exposed unlock button, preventing damage to the button and ensuring unlocking. Furthermore, the unlocking process is more convenient. In the locked state, the length of the locking rope 200 protruding from the housing support assembly 100 can be adjusted, ensuring the locked object has no room to move after being secured. This design also provides better compatibility for locking flexible materials such as electrical wires.

[0060] The locking cord 200 is, for example, a steel wire locking cord, and its diameter is, for example, 6mm, 4mm, 4.8mm, 3.5mm, 3mm, 2mm, 1.5mm, etc. Preferably, in some embodiments, the cross-sectional diameter of the locking cord 200 is less than 2mm, for example, 1.8mm, 1.5mm, 1.2mm, 0.8mm, etc. Because the diameter of the locking cord 200 can be set to a smaller diameter, the locking cord 200 can pass through keyholes with smaller diameters and can be installed and used in holes with a diameter of less than 2mm. This allows the steel wire rope padlock to be adapted to keyholes with smaller diameters, giving it high versatility.

[0061] In some embodiments, the fixed end 210 of the locking cord 200 is fixedly connected to the housing support assembly 100 via a fixing head 500. Specifically, the housing support assembly 100 includes a housing 110 and a support 120. A first channel 111 is disposed in the housing 110, and the support 120 is located inside the housing 110. The support 120 has a first receiving cavity 121, which communicates with the first channel 111. The locking / unlocking assembly 300 is at least partially disposed in the first receiving cavity 121. The fixed end 210 of the locking cord 200 is fixedly connected to the fixing head 500. The fixing head 500 passes through the housing 110 and is detachably connected to the support 120, for example, by a threaded connection. After the fixing head 500 is connected to the support 120, the fixing head 500, the housing 110, and the support 120 are relatively fixed. In some embodiments, a sealing ring is provided between the fixing head 500 and the housing 110, which is used for waterproofing and dustproofing.

[0062] In some embodiments, under normal conditions, the locking rope 200 can be fitted onto the object being locked, and the locking rope 200 moves toward the direction of passing through the first channel 111, so that the locking rope 200 can apply a binding force to the object being locked, so that the object being locked has no extra room for movement after being locked, and has better compatibility for locking flexible materials such as wires.

[0063] In some embodiments, the clamping member CM includes a pair of wedges 330 slidably disposed on the sliding sleeve 310, the pair of wedges 330 sliding along a first direction such that the pair of wedges 330 move closer or further away from each other, and a unidirectional guide bar 331 is disposed on the opposing surfaces of the wedges 330.

[0064] In normal conditions, the limiting member 320 enters the limiting groove 311 to limit the sliding sleeve 310. After the movable end 220 passes into the housing support assembly 100, the paired wedge blocks 330 can clamp the locking rope 200. The unidirectional guide bar 331 allows the locking rope 200 to move in the direction of entering the first channel 111 and prevents the locking rope 200 from moving in the direction of exiting the first channel 111.

[0065] In the unlocked state, the limiting member 320 exits the limiting groove 311, and the sliding sleeve 310 can move along the first direction to make the paired wedge blocks 330 move away from each other. The paired wedge blocks 330 release the locking rope 200, and the locking rope 200 can move in the direction of exiting the first channel 111.

[0066] In the above embodiment, the clamping member CM includes a pair of wedge blocks 330. The pair of wedge blocks 330 clamp the locking rope 200, which will not cause irreversible damage to the locking rope 200 and make the locking rope 200 have a longer service life.

[0067] In some embodiments, the unlocking and locking assembly 300 further includes a pair of sliding blocks 340, which are mounted opposite to each other on the sliding sleeve 310. Each sliding block 340 is provided with a first guide groove 341, which has a slope structure that matches the slope of the wedge block 330. Each wedge block 330 is slidably connected to a corresponding first guide groove 341. The sliding of the pair of wedge blocks 330 along the first guide groove 341 causes the pair of wedge blocks 330 to move closer to or further away from each other.

[0068] In the above embodiment, the relative sliding between the wedge block 330 and the sliding block 340 allows the paired wedge blocks 330 to move closer or further apart, achieving a stable structure for switching between clamping the locking rope 200 with the paired wedge blocks 330. The paired wedge blocks 330 will not cause irreversible damage to the locking rope 200, and compared to using screws to clamp the locking rope 200, the wire rope padlock has a longer service life.

[0069] In some embodiments, the housing support assembly 100 includes a housing 110 and a support 120. A first channel 111 is disposed in the housing 110. The support 120 is located inside the housing 110 and has a first receiving cavity 121 communicating with the first channel 111. The unlocking and locking assembly 300 is at least partially disposed in the first receiving cavity 121.

[0070] The inner wall of the first receiving cavity 121 is provided with a guide strip 1211 extending in a first direction. The outer wall of the sliding block 340 is provided with a second guide groove 342 that cooperates with the guide strip 1211; and / or the outer wall of the sliding sleeve 310 is provided with a third guide groove 312 that cooperates with the guide strip 1211.

[0071] In some embodiments, the housing support assembly 100 includes a housing 110 and a support 120. A first channel 111 is disposed in the housing 110. The support 120 is located inside the housing 110 and has a first receiving cavity 121, a second receiving cavity 122, and a connecting channel 124. The first receiving cavity 121 communicates with the first channel 111, and an unlocking / locking assembly 300 is at least partially disposed in the first receiving cavity 121.

[0090] The different states of the wire rope padlock in the above embodiments will be described below.

[0091] Figure 9 This is a cross-sectional schematic diagram of an embodiment of the wire rope padlock of the present invention under normal conditions. Figure 10 for Figure 9 A cross-sectional diagram along the AA direction is shown. Under normal conditions, the limiting member 320 enters the limiting groove 311. Under the force of the first elastic member 360, the elastic member base 350 overlaps with the waterproof adapter block 130. Under the force of the second elastic member 370, the wedge block 330's end facing the first channel 111 overlaps with the sliding block 340's end facing the first channel 111. The paired wedge blocks 330 can clamp the locking rope 200. The unidirectional guide rail 331 allows the locking rope 200 to move in the direction of entering the first channel 111 and prevents it from moving out of the first channel 111. That is, at this time, only pulling the locking rope 200 in the direction of entering the first channel 111 is allowed, and it cannot be pulled out. At this time, if the locking rope 200 is pulled further in the direction of entering the first channel 111, the wire rope padlock can be switched to a locked state.

[0092] Figure 11 This is a cross-sectional schematic diagram of an embodiment of the wire rope padlock of the present invention in the locked state. Figure 12 for Figure 11 A cross-sectional diagram along the BB direction is shown. Regarding the locked state, in the normal state, when the locking rope 200 is pulled further in the direction of insertion into the first channel 111, the second elastic element 370 is compressed, and the paired wedge blocks 330 are in a relatively relaxed state. The locking rope 200 can continue to be pulled in the direction of insertion into the first channel 111, and the space enclosed by the locking rope 200 will decrease; this state is the locked state. When the locking rope 200 is released, the second elastic element 370 returns to its original position, and the wire rope padlock returns to the normal state.

[0093] Figure 13 This is a cross-sectional schematic diagram of an embodiment of the wire rope padlock of the present invention in the unlocked state. Figure 14 for Figure 13A cross-sectional diagram along the CC direction is shown. Regarding the unlocked state, when an external wireless power supply device is inserted into the wireless power supply assembly 600, the wireless induction coil can supply power to the circuit board and wake up the Bluetooth module. At this time, the Bluetooth module of the wire rope padlock is connected via a handheld terminal, the key is identified, and an unlock command is sent to unlock the padlock. The rotating drive component 410 drives the drive wheel 440 to rotate. After rotating a certain angle, the drive wheel 440 abuts against the unlocking shaft 420 and drives the unlocking shaft 420 to rotate, causing the unlocking shaft 420 to overcome the elastic force of the reset component 460 and rotate. When the limiting component storage groove 421 of the unlocking shaft 420 aligns with the limiting component 320, the rotating drive component 410 stops rotating, and the wire rope padlock is now in the unlocked state. At this time, the lock rope 200 can be pulled outwards, and the limiting component 320 enters the limiting component storage groove 421. Under the tension of the lock rope 200, the unlocking and locking assembly 300 moves towards the first direction. The first elastic component 360 is in a compressed state, and the second elastic component 370 is in a reset state. At this time, the sliding block 340 moves to both sides under the action of the guide bar 1211, the paired wedge blocks 330 are in a relaxed state, and the locking rope 200 can be pulled outward, that is, the locking rope 200 can move in the direction of exiting the first channel 111. After the pulling force of the locking rope 200 is removed, the first elastic element 360 resets, the locking and unlocking assembly 300 returns to the default state, and at this time a locking command can be sent, the rotating drive 410 rotates, the limiting element 320 exits the limiting element storage groove 421 and enters the limiting groove 311 of the sliding sleeve 310, so that the wire rope padlock returns to the normal state.
