As shown in fig. 1 to 2, the present invention provides a retractable rope lock, which includes a lock housing 100 and a lock core 200 disposed in the lock housing 100. The rope of the rope lock can be stretched or stretched, the length of the rope lock can be adjusted according to the actual use length, and the rope lock is simple and convenient. In the present embodiment, the rope may be a steel wire rope, a nylon rope, a carbon fiber rope, various alloy ropes, or various mixed ropes (which may be a mixed rope of metal wires and plastic wires). The rope may be a chain rope.

Specifically, the lock housing 100 may include a first housing and a second housing, and the first housing and the second housing cover together to form a receiving cavity, and enclose the lock core 200 in the receiving cavity. As shown in fig. 3, the lock core 200 includes a rope winding wheel structure 210 disposed in the lock housing 100, a rope 220 wound around the rope winding wheel structure 210, and a first locking structure 230 correspondingly engaged with the rope winding wheel structure 220. The rope winding wheel structure 210 can wind the rope 220, and the first locking structure 230 can limit and lock the rope winding wheel structure 210, so that the rope winding wheel structure 210 is kept in a fixed state, namely, the rope 220 wound on the rope winding wheel structure 210 can be kept in a fixed length.

Further, as shown in fig. 4, the rope winding wheel structure 210 includes a rotating shaft disposed in the lock housing 100, a gear 212 rotatably sleeved on the rotating shaft, and a first restoring structure 214 disposed in the lock housing 100 and configured to tighten the rope 220. The gear 212 is free to rotate (including forward or reverse rotation) via the shaft to retract or extend the cable 220 to adjust the length of the cable. In addition, through setting up first reduction structure 214, can make the rope in the tight state at all times, avoid the rope to appear not hard up. In addition, the rope winding wheel structure 210 may further include a rope winding disc disposed coaxially (i.e., a rotating shaft) with the gear 212, and the rope 220 may be wound on the rope winding disc, so that when the gear 212 is rotated, the rope winding disc may be driven to rotate by the rotating shaft, and the rope winding disc may be unwound or retracted. In addition, the first restoring structure 214 may be disposed at the gear and may also be disposed at the rope reel. Further, the gear may be a spur gear, a helical gear, or another gear. In addition, the gear can be replaced by other gears with tooth grooves.

The first locking structure 230 includes a brake lever 232, a driving portion 234, and a second returning structure 236. The middle portion of the brake lever 232 is hinged in the lock housing 100, one end of the brake lever 232 corresponds to the tooth groove 2124 of the gear 212, and the other end of the brake lever 232 corresponds to the driving portion 234 provided on the lock housing 100. The driving portion 234 is used to press and rotate the brake lever 232, i.e., the brake lever 234 is limited from rotating in a first direction (one direction indicating the position of the tooth slot of the disengaging gear) and the brake lever 234 is allowed to rotate in a second direction (the other direction indicating the position of the tooth slot of the disengaging gear, opposite to the first direction), so that the brake lever can be ensured to disengage from the tooth slot only when rotating in the second direction. The second reset structure 236 is disposed in the lock housing 100 and can be used to reset the brake bar 232, that is, the second reset structure 236 has the capability of elastically limiting the brake bar 232 in the tooth space of the gear. When the brake lever is in the limit position of the second return structure 236, one end of the brake lever extends into the gear slot to limit the gear from rotating in the wire winding direction, while the gear can still rotate in the wire unwinding direction to drive the brake lever to rotate in the second direction.

The first locking structure 230 is similar to a lever structure, and the brake lever 232 can be rotated by pressing the driving portion 234 disposed on and partially exposed from the lock housing 100 (such that the driving portion 234 is partially exposed from the lock housing 100, so as to press the driving portion 234 from the outside), so that the brake lever 232 is disengaged from the tooth slot 2124 of the gear 212, and the gear 212 can be rotated by the first restoring structure 214 to be restored, so as to retract the rope. The driving portion 234 is fixed to the lock case 100 and does not come off the lock case 100. Moreover, when the gear 212 rotates in the forward direction (rotates in the direction of winding), one end of the brake lever 232 abuts against the teeth of the gear 212 to prevent the gear from rotating continuously, and at this time, the brake lever 232 will rotate in the reverse direction under the driving of the gear and will press the driving part 234 out of the lock housing, but the driving part 234 arranged on the lock housing will abut against the other end of the brake lever 232 to limit the brake lever 232, so that the gear 212 cannot drive the brake lever 232 to rotate in the reverse direction to disengage the end of the brake lever 232 from the tooth grooves of the gear, and the rope cannot be stretched or contracted; when the gear 212 is rotated in the reverse direction (rotation in the wire unwinding direction), the end of the brake lever 232 is disengaged from the notch 2124 of the gear 212 to allow the gear to continue rotating, thereby allowing the cable to be stretched, but not retracted. Further, it should be noted that whether the direction of rotation of the gear 212 is forward or reverse is primarily related to the position of the brake lever. In this embodiment, the rotation direction of the gear when the winding pulley structure 210 winds the wire may be defined as the gear forward rotation, and the rotation direction of the gear when the winding pulley structure 210 pays the wire may be defined as the gear reverse rotation. In addition, a limiting structure for limiting the brake lever 232 can be additionally arranged in the lock shell, so that the brake lever 232 is prevented from rotating reversely and cannot abut against gear teeth of the gear when the gear rotates forwards.

In this way, under normal conditions (i.e. when no external force is applied), the first locking structure 230 can lock the pulley structure 210, i.e. the brake lever 232 of the first locking structure 230 abuts against the tooth root position of the gear teeth 2124 of the gear 212 to lock the gear 212, so as to lock and limit the rope 220 wound on the gear 212, and prevent the rope 220 from retracting (i.e. winding) onto the gear 212. When the length of the rope 220 needs to be adjusted to stretch the rope, the rope 220 can be directly stretched, at this time, the gear 212 rotates reversely when the pulling force applied to the gear 212 is greater than the restoring force of the first restoring structure 214, the end of the brake rod 232 disengages from the tooth socket 2124 of the gear 212, the brake rod 232 does not limit the position of the gear 212 so that the gear 212 can continue to rotate, so that the rope 220 can be continuously pulled out, when the rope 220 is pulled out for the required length and is not stretched any more, the pulling force applied to the rope 220 disappears and only the restoring force of the first restoring structure 214 is applied, that is, the gear 212 rotates forward when the force of the first restoring structure 214 is applied, so that the end of the brake rod 232 reenters the tooth socket 2124 of the gear 212 under the restoring force of the second restoring structure 236 and is clamped against the tooth socket 2122 of the gear 212 to limit the gear 212, i.e., a length that allows the cords 220 to remain stretched. In the process of pulling out the rope 220, the first locking structure 230 can be pulled out without pressing the driving part 234, the operation is convenient and simple, and the phenomenon of blocking is not easy to occur. When the rope 220 needs to be retracted, the driving part 234 of the first locking structure 230 is pressed, the driving part 234 rotates the brake lever 232 against the return force of the second return structure 236, so that the end of the brake lever 232 is disengaged from the tooth slot 2124 of the gear 212, and the gear 212 loses the limit of the brake lever 232 and rotates under the return force of the first return structure 214, so that the rope 220 is automatically retracted and wound on the gear 212.

the brake lever 232 includes a brake main body hinged to the lock case 100, a locking portion provided at one end of the brake main body and corresponding to the tooth groove 2124 of the gear 212, and a brake portion provided at the other end of the brake main body in an inclined manner, and the brake portion and the driving portion 234 correspond to each other. In this way, the brake lever 232 can be configured as an L-shaped rod, the long rod portion of the brake lever 232 can be configured as a brake main body, the short rod portion thereof can be configured as a brake portion, the hinge portion of the brake lever 232 can be provided at a connecting position of the brake main body and the brake portion, and the second returning structure 236 can be provided at the connecting position, thereby facilitating the rotation of the brake main body by the brake portion and facilitating the returning of the brake lever 232 by the second returning structure 236. When the driving part 234 is pressed, the driving part 234 presses the braking part, and the driving part applies pressure to the braking part, so that the braking main body rotates against the reset force of the second reset structure 236, and the locking part is disengaged from the tooth groove 2124 of the gear 212, so that the braking lever loses the limit locking effect on the gear 212. In addition, in this embodiment, the driving portion 234 may be a button movably mounted on the lock housing, a portion of the button is exposed outside the lock housing, another portion of the button extends into the lock housing and vertically corresponds to the braking portion, and the button cannot be disengaged from the lock housing. The driving portion 234 may be provided as another component that can rotate with the brake lever, such as a rotating disc connected to the center of rotation or the braking portion of the brake lever.

In addition, in this embodiment, the first returning structure 214 can be a spiral spring, and when the brake lever 232 is disengaged from the gear 212, the gear 212 can rotate freely, so that the rope 220 can be automatically tightened on the gear 212 by the returning action of the spiral spring, and the rope 220 can be contracted and wound. The second returning structure 236 may be a torsion spring structure, and when the driving part 234 stops pressing the rotary brake lever 232, the brake lever 232 is automatically returned by the elastic force of the torsion spring structure, so that the end of the brake main body of the brake lever 232 is re-engaged in the tooth slot 2124 of the gear 212, and the gear 212 is re-limited, thereby limiting the rope 220 to a fixed length.

In addition, as shown in fig. 5 to 6, the lock core 200 further includes a second locking structure 240 disposed in the lock housing 100, and the second locking structure 240 is correspondingly engaged with the gear 212. The second locking structure 240 can be locked and unlocked with the gear 212, and the gear 212 can be doubly locked by combining the first locking structure 230, so that the locking and unlocking of the rope 220 are more reliable. Specifically, the second locking structure 240 includes a driving mechanism 242 (shown in fig. 2) disposed in the lock housing 100, and a locking block structure 244 connected to the driving mechanism 242 for locking and unlocking the gear 22. The driving mechanism 242 can drive the locking block structure 244 to move to lock and unlock the gear 212, so that the rope 220 can be limited and fixed or stretched and contracted. That is, when the second locking structure 240 locks the gear 212 with the locking block structure 244, the rope 220 is fixed, i.e., the rope 220 cannot be stretched or contracted; when the second locking structure 240 does not lock the gear 212 with the locking block structure 244, a semi-locking of the rope 220 is achieved, i.e. the rope 220 can be stretched but cannot be retracted. When the gear 212 is further unlocked by the brake lever 232 of the first locking structure 230, the rope 220 can be retracted.

Further, the driving mechanism 242 includes a driving circuit 2422 disposed in the lock housing 100, and a driving motor 2424 connected to the driving circuit 2422, wherein the driving motor 2424 is connected to the locking block structure 244. That is, the driving circuit 2422 can be used to control the start and stop of the driving motor 2424 and to control the forward rotation and the reverse rotation of the driving motor 2424, so that the driving motor 2424 can be used to drive the locking block structure 244 to move, so as to lock or unlock the gear 212. Further, the driving circuit 2422 may include a main control circuit, and a fingerprint recognition module, a face recognition module, or an iris recognition module connected to the main control circuit. That is, the main control circuit may be driven by the biometric recognition module such as the fingerprint recognition module, the face recognition module, and the iris recognition module, so that the main control circuit drives the driving motor 2424. In this embodiment, the fingerprint identification module may be utilized to control the main control circuit, that is, the driving motor 2424 may be started to rotate forward or backward by inputting a fingerprint, so as to lock or unlock the gear 212. In addition, it should be noted that the fingerprint identification module, the face identification module or the iris identification module may all adopt the prior art, for example, the fingerprint identification module may adopt a fingerprint module adopted by all fingerprint card readers for daily attendance and attendance card punching of a common company, the face identification module may also adopt a face identification module adopted by all face identification card readers for daily attendance and attendance card punching of a common company, and the corresponding control circuit may also apply a part of circuits in these daily card readers. In addition, the prior art can be adopted for the iris recognition module.

In addition, the locking block structure 240 includes a locking hook rod 2442 connected to the driving motor 2424 at a middle portion, that is, the middle portion of the locking hook rod 2442 is connected to an output shaft of the driving motor, and an included angle is formed between the locking hook rod and the output shaft of the driving motor, so that the driving motor can drive the locking hook rod to rotate around the output shaft. The lock further comprises a sliding plate 2444 arranged in the lock shell 100 and located on one side of the gear, and a locking sliding block 2446 arranged on the sliding plate 2444 in a sliding mode, the bottom end of the locking sliding block 2446 corresponds to a tooth groove of the gear 212, and the locking sliding block 2446 is used for locking and unlocking the gear teeth of the gear 212. Also, one end of the locking hook lever 2442 corresponds to a tip end of the locking slider 2446, and the locking hook lever 2442 is used to push the locking slider 2446 to slide in a direction of entering or leaving a wheel groove of the gear under driving of the driving motor, i.e., to push the locking slider 2446 into or out of a tooth groove 2124 of the gear 212. The latch hook bar 2442 can be driven to rotate by the driving motor 2424, so as to drive the locking slider 2446 to slide on the sliding plate 2444 toward the tooth groove of the gear, and the locking slider 2446 can move into the tooth groove 2124 of the gear 212 to lock the gear 212 for realizing the limit of the gear 212, or the locking slider 2446 can move out of the tooth groove 2124 of the gear 212 to release the limit of the gear 212. In addition, in the present embodiment, the locking slider 2446 can be moved into or out of the tooth groove 2124 of the gear 212 by sliding up and down, or can be moved into or out of the tooth groove 2124 of the gear 212 by sliding left and right (or back and forth).

Moreover, the locking slider 2446 may include a locking block main body slidably disposed on the sliding plate, a locking head disposed at one end of the locking block main body and corresponding to the tooth groove of the gear, and an inclined pushing block disposed at the other end of the locking block main body and corresponding to the end of the locking hook rod. The latch hook rod can push the inclined push block under the driving of the driving motor to drive the latch block main body and the latch head to slide on the sliding plate, that is, when the latch hook rod 2442 rotates towards the latch slide block 2446 under the driving of the driving motor, the latch hook rod 2442 gradually moves towards the inclined push block and pushes the inclined push block downwards, and the inclined push block drives the latch block main body to move in the tooth socket direction of the upper and lower gears 212 of the sliding plate, so that the latch head is clamped in the tooth socket 2124 of the gears 212.

Moreover, this oblique ejector pad is including locating the ejector pad main part of locking piece main part tip to and set up on this ejector pad main part, and the inclined plane that corresponds with the tip of latch hook member, latch hook member can exert bigger and bigger pressure to the inclined plane at the rotation in-process, makes the oblique ejector pad slide on the slide. Moreover, the locking block structure 244 further includes a third restoring structure 2448 disposed on the sliding plate 2444 for restoring the locking block 2446, and the third restoring structure 2448 may also be a torsion spring structure. Through the third reset structure 2448 for resetting the locking sliding block 2446, when the locking hook rod 2442 is driven by the driving motor 2422 to rotate, the locking hook rod 2442 can move along the lowest position of the inclined surface of the inclined pushing block to the highest position of the inclined surface of the inclined pushing block, so that the inclined pushing block and the locking block main body are subjected to downward pressure, and the pressure can press the whole locking sliding block 2446 to slide downwards along the sliding plate 2444 after the spring force of the third reset structure 2448 is overcome, so that the locking head at the end part of the locking sliding block 2446 moves downwards and is clamped in the tooth groove 2124 of the gear 212, and the locking of the gear 212 is realized. When the driving motor 2424 rotates reversely, the latch hook rod 2442 moves along the highest position of the inclined surface of the inclined pushing block to the lowest position thereof, so that the pressure applied to the inclined pushing block and the whole locking slider 2446 gradually disappears, and at this time, the spring force of the third resetting structure 2448 can make the whole locking slider 2446 slide upwards along the sliding plate 2444 and reset the locking slider 2446, so that the locking head at the end of the locking slider 2446 is disengaged from the tooth groove 2124 of the gear 212, and the locking of the gear 212 is released.

Furthermore, the latch hook rod 2442 may include a lock rod body disposed at one side of the sliding plate, the middle of the lock rod body is connected to the output shaft of the driving motor 2424, and an included angle is formed between the lock rod body and the output shaft of the driving motor. The latch hook rod 2442 further includes a push head disposed at one end of the lock rod and corresponding to the slanted push block of the locking slider, and a hook disposed at the other end of the lock rod and corresponding to the inner structure of the lock core. The pushing head can be used for pushing the inclined pushing block and the sliding plate of the locking block main body to slide under the driving of the driving motor and the locking rod body, namely when the locking rod body rotates by an angle, the pushing head can push the locking sliding block into or out of a gear tooth groove. Moreover, the hook body can be used for being hooked and fixed on the inner structure of the lock core under the driving of the driving motor and the lock rod body, namely when the lock rod body rotates by another angle, the hook body can be hooked and fixed on the inner structure of the lock core. That is, by respectively disposing the pushing head and the hook body at the two ends of the latch hook rod 2442, in the process of rotating the latch hook rod 2442 by the driving motor 2424, not only the pushing head can be used to push the inclined pushing block and the locking slider, but also the hook body can be used to lock the entire latch hook rod 2442, so that the entire locking block structure 233 can stably and reliably lock the gear 212, and is not easily disengaged. Moreover, a slot may be formed on the gear teeth 2122 of the gear 212, and the shape of the slot corresponds to the shape of the locking head of the locking slider 2446, so that the locking head is conveniently clamped and is not easily separated from the tooth slot 2124. In addition, in order to ensure that the pushing head is not easy to deviate from the inclined pushing block, the pushing head can be designed into an inclined structure matched with the inclined pushing block, and in addition, a corresponding limiting groove can be arranged on the inclined pushing block or the pushing head. In addition, in this embodiment, the locking rod body can be horizontally and horizontally connected to the output shaft of the driving motor, and the output shaft is further connected to the middle position of the locking rod body, so that the rotation of the locking rod body is more reliable.

in addition, in addition to converting the rotation of the latch hook lever 2442 into the up-and-down sliding of the locking slider 2446 by using the above-described inclined push block, the rotation of the latch hook lever 2442 may be converted into the up-and-down sliding of the locking slider 2446 by a screw nut structure (or the rotation of the output shaft of the driving motor is converted into the up-and-down movement of the latch hook lever and the locking slider directly by the screw nut structure).

The telescopic rope lockset provided by the utility model utilizes the reverse braking principle to reasonably design the gear and the brake lever, so that the rope can be positioned at a very high speed no matter how long the rope is pulled; the rope can be freely stretched and locked by a simple mechanism, and a brake rod and a gear do not need to be manually separated, so that the operation habit is improved, and the design is simplified; in addition, the starting and stopping of the driving motor can be controlled by matching with a fingerprint identification technology (or other intelligent identification technologies), and a rope lock head can be buckled and a gear can be locked by adopting a double locking technology; the portable mobile phone is small and portable, the use rapidity is enhanced, and the safety and the privacy are ensured.
