[0009] Preferably, a first slot is provided in the middle of the long blind hole, and the first slot communicates with the inside of the long blind hole. Two second slots are provided in the middle of the long through hole, and the two second slots are arranged along the length direction of the long through hole, and the second slots communicate with the inside of the long through hole. The locking actuator includes an end actuator and a middle actuator. The end actuator and the middle actuator are both movably installed on one side of the bracket. The end actuator corresponds to the first slot, and the middle actuator corresponds to the two second slots. The end actuator can move in the direction of approaching or departing from one end of the steel cable through the first slot under the drive of the guide rail, so that the end actuator locks or does not lock one end of the steel cable. The middle actuator can move in the direction of approaching or departing from the middle of the steel cable through the two second slots under the drive of the guide rail, so that the middle actuator locks or does not lock the middle of the steel cable.

[0010] Preferably, the guide rail includes an outer rail edge and an inner rail groove. The outer rail edge is provided at a part of the outer circumference of the rail turntable. The remaining part of the outer circumference of the rail turntable is an arc section. A special-shaped hole is provided in the middle of the rail turntable.

The inner track groove includes a first segment, a second segment, and a third segment connected in sequence. One end of the first segment is arranged close to the second end of the outer track edge, and one end of the third segment is arranged close to the first end of the outer track edge. The outer edges of the first segment, the second segment, and the third segment together form an arc. The distance between the inner edge of the first segment and the special-shaped hole is less than the distance between the inner edge of the third segment and the special-shaped hole, and the inner edge and the outer edge of the first segment have the same trend. The inner edge and the outer edge of the third segment have the same trend. The distance between the inner edge of the second segment and the special-shaped hole first decreases and then increases, and a clearance area is formed in the middle of the third segment. The driving end of the end actuator is embedded in the inner track groove. When the track turntable rotates, the first segment, the second segment, and the third segment can act on the driving end of the end actuator in sequence, and move the end actuator in the direction close to or away from one end of the steel cable.

[0012] Preferably, the middle actuator includes a steel cable brake and a reed. A limiting protrusion is provided on the outer edge of the bracket. A clamping hole for the middle of the steel cable to pass through is provided in the middle of the steel cable brake.

A middle cylindrical protrusion is provided in the groove. The reed is embedded in the groove and sleeved on the outer circumference of the middle cylindrical protrusion. The middle cylindrical protrusion is the driving end of the middle actuator. The limiting protrusion is located on the side of the reed away from the steel cable brake. When the outer track edge rotates and drives the middle cylindrical protrusion to move away from the middle of the steel cable to the side where the reed is pressed against the limiting protrusion, the clamping section can contact and clamp the outer circumference of the middle of the steel cable at the two second slots. When the outer track edge rotates in the opposite direction, the reed can reset in the direction away from the limiting protrusion, and drive the middle cylindrical protrusion to move in the direction close to the middle of the steel cable until the clamping section disengages from the middle of the steel cable.

[0013] Preferably, the end operating member includes a locking brake, a locking brake spring and a single-hole elastic member. An arc-shaped groove is provided at the first end of the locking brake. A ring-shaped groove is provided at the position of the steel cable corresponding to the arc-shaped groove. The arc-shaped groove can be clamped in the ring-shaped groove. A end cylindrical protrusion is fixed on the end surface of the first end of the locking brake near the track turntable. The end cylindrical protrusion is embedded in the inner track groove. An installation plate is further provided in the middle of the locking brake. An installation column is fixed on one side of the installation plate close to the middle operating element.

A locking column is installed on the inner bottom surface of the long blind hole. A limiting long hole is provided on the side wall of the long blind hole. The single-hole elastic member is located on the side of the locking column away from the inner bottom surface of the long blind hole. A long column for protruding out of the limiting long hole is provided on the single-hole elastic member. When one end of the steel cable is inserted into the long blind hole, the single-hole elastic member can be compressed in the direction close to the locking column. When the locking brake releases the limit on one end of the steel cable, the single-hole elastic member resets and pushes one end of the steel cable out of the long blind hole. When the track turntable rotates to make the end cylindrical protrusion move relatively in the first section, the inner edge of the first section can push the end cylindrical protrusion to move in the direction close to one end of the steel cable until the arc-shaped groove clamps the ring-shaped groove. At this time, the locking brake spring gradually resets and elongates. When the track turntable rotates to make the end cylindrical protrusion move relatively in the second section, the locking brake spring can reciprocate in the clearance area. When the track turntable rotates to make the end cylindrical protrusion move relatively in the third section, the inner edge of the third section can push the end cylindrical protrusion to move in the direction close to one end of the steel cable until the arc-shaped groove clamps the ring-shaped groove. At this time, the locking brake spring is in the reset and elongated state.

[0014] Preferably, the locking part further includes a lock housing. The lock housing is buckled on the side of the bracket away from the lock head. And the locking operating member is located in the lock housing. Three through holes are provided on the side wall of the lock housing.

[0016] Preferably, one end of the rotating shaft of the lock head is a special-shaped shaft, and the special-shaped shaft can extend into the special-shaped hole and be limitedly connected with the special-shaped hole.

Detailed implementation manners

[0031] Next, the technical solutions in the embodiments of the present invention will be clearly and completely described in conjunction with the accompanying drawings in the embodiments of the present invention. Obviously, the described embodiments are only a part of the embodiments of the present invention, rather than all the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those of ordinary skill in the art without making creative efforts shall fall within the protection scope of the present invention.

[0032] The purpose of the present invention is to provide a steel cable lock to solve the problems existing in the prior art and improve the anti-theft effect.

[0033] To make the above objects, features, and advantages of the present invention more obvious and understandable, the present invention will be further described in detail below in conjunction with the accompanying drawings and specific implementation manners.

[0034] As shown Figures 1 - 10 in the figure, this embodiment provides a steel cable lock, which includes a lock body assembly, an orbital turntable 5, and a steel cable 4. The lock body assembly includes a lock head and a locking part. The lock head is connected to one end of the locking part. The orbital turntable 5 is located at the other end of the locking part, and the rotating shaft of the lock head can pass through the locking part and be connected to the orbital turntable 5. Then, by rotating the lock head, the rotating shaft of the lock head drives the orbital turntable 5 to rotate. The steel cable 4 is U-shaped. The middle part of the steel cable 4 can pass through the locking part and be locked by the locking part, and one end of the steel cable 4 can extend into the lock body assembly and be locked by the lock body assembly. Thus, both the middle part and one end of the steel cable 4 are locked simultaneously, realizing double locking between the steel cable 4 and the locking part, improving the locking effect. On the side of the orbital turntable 5 close to the locking part, there is a guide rail. The lock head can drive the orbital turntable 5 to rotate, and when the orbital turntable 5 rotates, it can act on the locking part through the guide rail, and make the locking part lock or unlock the steel cable 4. By reasonably setting the shape of the guide rail and making the guide rail cooperate with the locking part, when using the locking part to lock the steel cable 4, the guide rail can limit the position of the locking part, ensuring that the lock gate 10 can be completely locked, preventing unlocking by pick technology, and improving the anti-theft effect.

[0035] Specifically, the locking part includes a bracket 6 and a locking actuator. The bracket 6 serves as a supporting main body and functions as an installation platform. Both the middle part and one end of the steel cable 4 can pass through the bracket 6. The locking actuator can lock the middle part and one end of the steel cable 4 on the bracket 6 to fix the steel cable 4 on the bracket 6. Then, the bicycle etc. can be locked through the steel cable 4. The locking actuator is installed on one side of the bracket 6, and the lock head is installed on the other side of the bracket 6. The rotating shaft of the lock head can pass through the bracket 6 and be connected to the middle part of the orbital turntable 5. When the rotating shaft of the lock head drives the orbital turntable 5 to rotate, the locking actuator can act along with the rotation of the orbital turntable 5 to lock or unlock the steel cable 4.

[0036] The bracket 6 is provided with a long blind hole 8 and a long through hole 9 on the side for installing the locking actuator. The length directions of the long blind hole 8 and the long through hole 9 are parallel, and the middle part of the steel cable 4 can pass through the long through hole 9, and one end of the steel cable 4 extends into the long blind hole 8. The locking actuator is installed on the bracket 6 at the position corresponding to the long blind hole 8 and the long through hole 9, and the locking actuator can, under the drive of the guide rail, lock the middle part of the steel cable 4 in the long through hole 9 and lock one end of the steel cable 4 in the long blind hole 8. Thus, the locking actuator limits the position of one end of the steel cable 4 at the long blind hole 8, and limits the position of the middle part of the steel cable 4 at the long through hole 9. And during actual locking, it can lock both a single loop and a double loop, and can be freely switched according to the user's needs, enabling the user not to repeatedly buy different locks, thus achieving the purpose of multiple uses of one lock.

[0037] A first slot 23 is provided in the middle of the long blind hole 8, and the first slot 23 communicates with the inside of the long blind hole 8. Two second slots 24 are provided in the middle of the long through hole 9. The two second slots 24 are arranged along the length direction of the long through hole 9, and the second slot 24 communicates with the inside of the long through hole 9. Thus, the locking action member can lock the steel cable 4 at the first slot 23 and the second slot 24 respectively.

[0038] The locking action member includes an end action member and a middle action member. Both the end action member and the middle action member are movably installed on one side of the bracket 6. The end action member corresponds to the first slot 23, and the middle action member corresponds to the two second slots 24. The end action member can move in the direction close to or away from one end of the steel cable 4 through the first slot 23 driven by the guide rail. When the end action member moves to the first slot 23, it can lock one end of the steel cable 4 at the first slot 23. When the end action member moves away from the first slot 23, the end action member no longer contacts one end of the steel cable 4, realizing the unlocking of one end of the steel cable 4. The middle action member can move in the direction close to or away from the middle of the steel cable 4 through the two second slots 24 driven by the guide rail. Similarly, when the middle action member moves to the second slot 24, it can lock the middle of the steel cable 4 at the second slot 24. When the middle action member moves away from the second slot 24, the middle action member no longer contacts the middle of the steel cable 4, realizing the unlocking of the middle of the steel cable 4.

[0039] The guide rail includes an outer rail edge 25 and an inner rail groove 30, and the outer rail edge 25 is used to cooperate with the middle action member, and the inner rail groove 30 is used to cooperate with the end action member.

[0040] The part of the outer track edge 25 disposed on the outer periphery of the track turntable 5, the remaining part of the outer periphery of the track turntable 5 is an arc segment, that is, the outer track edge 25 and the arc segment together form the outer ring of the track turntable 5. An irregular hole 26 is provided in the middle of the track turntable 5. The distance between the first end of the outer track edge 25 and the irregular hole 26 is less than the distance between the second end of the outer track edge 25 and the irregular hole 26, and from the first end of the outer track edge 25 to the second end of the outer track edge 25, the distance between the outer track edge 25 and the irregular hole 26 gradually increases. The driving end of the middle actuator is located on the outer periphery of the track turntable 5, so as to drive the middle actuator to move linearly with the rotation of the track turntable 5. The specific process is as follows: when the track turntable 5 rotates in the first direction, the first end of the outer track edge 25 first contacts the driving end of the middle actuator. As the track turntable 5 continues to rotate, the middle part and the second end of the outer track edge 25 gradually contact the driving end of the middle actuator, causing the driving end of the middle actuator and the middle actuator to gradually move away from the irregular hole 26 of the track turntable 5, that is, gradually move towards the middle of the steel cable 4 until the middle of the steel cable 4 is locked at the second slot 24. When the track turntable 5 rotates in the second direction, the second end of the outer track edge 25 first contacts the driving end of the middle actuator. As the track turntable 5 continues to rotate, the middle part and the first end of the outer track edge 25 gradually contact the driving end of the middle actuator, causing the driving end of the middle actuator and the middle actuator to gradually move towards the irregular hole 26 of the track turntable 5, that is, gradually move away from the middle of the steel cable 4 until it disengages from the middle of the steel cable 4, realizing the unlocking of the middle of the steel cable 4, and the first direction is opposite to the second direction.

[0041] The inner track groove 30 is opened on the end surface of the track turntable 5 near the bracket 6, and the inner track groove 30 is set corresponding to the arc segment to ensure that it can act on the end action piece. The inner track groove 30 includes a first section 27, a second section 28 and a third section 29 that are connected and connected in sequence. One end of the first section 27 is set close to the second end of the outer track edge 25, and one end of the third section 29 is set close to the first end of the outer track edge 25. The outer edge of the first section 27, the outer edge of the second section 28 and the outer edge of the third section 29 together form an arc. The distance between the inner edge of the first section 27 and the special-shaped hole 26 is smaller than the distance between the inner edge of the third section 29 and the special-shaped hole 26, and the first section The inner edge of the third section 29 is in the same direction as the outer edge of the first section 27, the inner edge of the third section 29 is in the same direction as the outer edge of the third section 29, the distance between the inner edge of the second section 28 and the special-shaped hole 26 is first reduced and then increased, and a clearance zone is formed in the middle of the third section 29, and the driving end of the end action piece is embedded in the inner track groove 30, so that as the track turntable 5 rotates, different positions in the inner track groove 30 contact and act on the driving end of the end action piece to achieve linear movement of the end action piece; when the track turntable 5 rotates, the first section 27, the second section 28 and the third section 29 can act on the driving end of the end action piece in sequence. The specific process is that when the track turntable 5 moves along the second When the track turntable 5 rotates in the direction of rotation, one end of the first section 27 first contacts the driving end of the end action piece. Since the distance between the inner edge of the first section 27 and the shaped hole 26 is small, that is, the inner edge of the first section 27 protrudes outward, and then when contacting the driving end of the end action piece, the end action piece is pushed outward, so that the end action piece gradually moves toward the direction close to the first slot 23, thereby locking one end of the steel cable 4. When the track turntable 5 rotates to make the driving end of the end action piece located in the second section 28, the inner edge of the second section 28 is concave inward to form an escape zone, so that the driving end of the end action piece can reciprocate in the escape zone, so that one end of the steel cable 4 can be in the long blind. The end action piece can freely move in the hole 8 to realize the automatic rebound locking of the end action piece. In this position, the steel cable lock in this embodiment can be as convenient as an automatic rebound lock, and can switch back and forth between the two states of safety and convenience; when the track turntable 5 rotates to make the driving end of the end action piece located in the third section 29, since the inner edge of the third section 29 protrudes outward, and the inner edge and outer edge of the third section 29 are in the same direction, the inner edge and outer edge of the third section 29 can simultaneously limit the driving end of the end action piece, so that the end action piece cannot be retracted under the action of external forces such as a paddle, thereby achieving the purpose of locking, preventing it from being unlocked by a paddle technique, and improving the anti-theft effect. Similarly, when the track turntable 5 rotates along the first direction, the driving end of the end action piece can gradually move away from the first slot 23 when cooperating with the first section 27, so as to unlock one end of the steel cable 4.

[0042] The middle moving part includes a steel cable brake 19 and a reed 20. A limiting protrusion 22 is provided on the outer edge of the bracket 6. The limiting protrusion 22 is used to cooperate with the reed 20 for limiting. A clamping hole 31 for the middle part of the steel cable 4 to pass through is provided in the middle of the steel cable brake 19. Preferably, two extension segments 32 are provided on both sides of the steel cable brake 19 for cooperating with the two second slots 24 for limiting. The clamping hole 31 is formed on the extension segment 32. A clamping section is provided on the inner ring of the clamping hole 31. The clamping section is arranged close to the axis of the track turntable 5, and the inner wall of the clamping section can be tightly attached to the outer periphery of the steel cable brake 19. One end of the steel cable brake 19 is slidably arranged on one side of the bracket 6, and a groove 33 is provided on the end face of the steel cable brake 19 away from the bracket 6. The groove 33 is formed on the end face between the two extension segments 32. A middle cylindrical protrusion 21 is provided in the groove 33. The reed 20 is embedded in the groove 33 and sleeved on the outer periphery of the middle cylindrical protrusion 21. The middle cylindrical protrusion 21 is the driving end of the middle moving part and is used to cooperate with the outer track edge 25. The limiting protrusion 22 is located on the side of the reed 20 away from the steel cable brake 19. Then, when the steel cable brake 19 drives the reed 20 to move away from the steel cable 4, due to the limitation between the limiting protrusion 22 and the reed 20, the limiting protrusion 22 prevents the reed 20 from moving. At this time, the reed 20 is deformed and stores energy, so as to facilitate the subsequent reset of the reed 20 and push the steel cable brake 19 to move towards the steel cable 4. The specific process is as follows: when the track turntable 5 drives the outer track edge 25 to rotate and makes the first end of the outer track edge 25 contact the middle cylindrical protrusion 21 first, at this time, since the outer track edge 25 gradually protrudes outwards, the middle cylindrical protrusion 21 is pushed to move away from the middle part of the steel cable 4 until the reed 20 is pressed against one side of the limiting protrusion 22. At this time, the reed 20 is deformed and stores energy, and the clamping section contacts and clamps the outer periphery of the middle part of the steel cable 4 at the two second slots 24, realizing the locking of the steel cable 4. When the track turntable 5 drives the outer track edge 25 to rotate in the reverse direction, since the outer track edge 25 gradually contacts and limits the middle cylindrical protrusion 21 at this time, the reed 20 can reset towards the direction away from the limiting protrusion 22 and drive the middle cylindrical protrusion 21 to move towards the middle part of the steel cable 4 until the clamping section disengages from the middle part of the steel cable 4, realizing unlocking.

[0043] The end actuator includes a locking brake 10, a locking brake spring 14, and a single-hole elastic member 15. An arc-shaped groove 34 is provided at the first end of the locking brake 10, and the inner wall of the arc-shaped groove 34 can be attached to the outer wall of the steel cable 4 and lock the outer circumference of the steel cable 4. The steel cable 4 is provided with an annular groove at a position corresponding to the arc-shaped groove 34, and the annular groove is provided corresponding to the first slot 23. The arc-shaped groove 34 can be clamped in the annular groove, thereby locking one end of the steel cable 4 at the annular groove. A end cylindrical protrusion 11 is fixed on the end face of the first end of the locking brake 10 close to the track turntable 5. The end cylindrical protrusion 11 is embedded in the inner track groove 30, and it can be realized that the end cylindrical protrusion 11 is driven to move through the inner track groove 30. An installation plate 12 is further provided in the middle of the locking brake 10. An installation column 13 is fixed on one side of the installation plate 12 close to the middle actuator. One end of the locking brake spring 14 is sleeved on the outer circumference of the installation column 13 and connected to the installation plate 12, and the other end of the locking brake spring 14 is connected to the bracket 6. When the locking brake 10 locks one end of the steel cable 4, the locking brake spring 14 is in an extended state. The single-hole elastic member 15 is installed in the long blind hole 8. A locking column 18 is installed on the inner bottom surface of the long blind hole 8. A limiting long hole 17 is provided on the side wall of the long blind hole 8. The single-hole elastic member 15 is located on the side of the locking column 18 away from the inner bottom surface of the long blind hole 8, and a long column 16 for protruding out of the limiting long hole 17 is provided on the single-hole elastic member 15. As one end of the steel cable 4 is inserted into or withdrawn from the long blind hole 8, the single-hole elastic member 15 can be pushed to move towards or away from the locking column 18, thereby compressing or releasing the single-hole elastic member 15. During this process, the moving stroke of the long column 16 is the length of the limiting long hole 17. Based on this, when one end of the steel cable 4 extends into the long blind hole 8 and compresses the single-hole elastic member 15, the locking brake 10 locks one end of the steel cable 4. When the locking brake 10 releases the limit on one end of the steel cable 4, the single-hole elastic member 15 resets and pushes one end of the steel cable 4 out of the long blind hole 8, realizing automatic ejection and improving the use feeling. When the track turntable 5 rotates to make the end cylindrical protrusion 11 move relatively within the first section 27, the inner edge of the first section 27 can push the end cylindrical protrusion 11 towards the direction close to one end of the steel cable 4 until the arc-shaped groove 34 catches the annular groove. At this time, the locking brake spring 14 gradually resets and extends. When the track turntable 5 rotates to make the end cylindrical protrusion 11 move relatively within the second section 28, the locking brake spring 14 can reciprocate within the clearance area. When the track turntable 5 rotates to make the end cylindrical protrusion 11 move relatively within the third section 29, the inner edge of the third section 29 can push the end cylindrical protrusion 11 towards the direction close to one end of the steel cable 4 until the arc-shaped groove 34 catches the annular groove. At this time, the locking brake spring 14 is in a reset and extended state.

[0044] Through the above design, the steel cable lock in this embodiment can achieve three states, namely the unlocking state, the spring-back locking state, and the locked state, where:

[0045] Unlocked state: the lock gate 10 leaves the first slot 23 under the elastic restoring force of the lock gate spring 14, the cable gate 19 is pressed against the spring sheet 20, and the clamping section on the cable gate 19 is separated from the second slot 24. At this time, one end of the cable 4 (i.e., the cable 4 plug) is pushed out by the single-hole elastic member 15. Since there is a compression spring at the tail of the single-hole elastic member 15, after one end of the cable 4 is inserted, it presses against the single-hole elastic member 15, compressing the compression spring. When the lock gate 10 is pushed away from the first slot 23 by the lock gate spring 14, one end of the cable 4 is bounced open by the single-hole elastic member 15.

[0046] Rebound locked state: At this time, the lock gate 10 is pushed into the first slot 23 of the long blind hole 8 under the action of the elastic restoring force of the lock gate spring 14. Since the end cylindrical protrusion 11 of the lock gate 10 is located in the second section 28 of the inner track groove 30 at this time, the lock gate 10 can withdraw from the first slot 23 under the action of external force, and the steel cable gate 19 is still separated from the second slot 24 at this time. In this state, the steel cable 4 at the long through hole 9 and the steel cable gate 19 can move freely. As the first end of the steel cable 4 is inserted into the long blind hole 8, the lock gate 10 is pushed out of the first slot 23 under the action of the first end of the steel cable 4, and the lock gate spring 14 is compressed to store energy. When the first end of the steel cable 4 is inserted into place, the lock gate 10 is not blocked due to the setting of the annular groove on the outer periphery of the steel cable 4, and can automatically enter the long blind hole 8 through the first slot 23 immediately under the action of the elastic restoring force of the lock gate spring 14. The first end of the steel cable 4 is automatically locked through the matching limit of the arc groove 34 on the lock gate 10 and the annular groove at one end of the steel cable 4. At this time, the lock gate 10 has an automatic locking function.

[0047] Locked state: At this time, the central cylindrical protrusion 21 of the lock gate 10 is located in the third section 29 of the inner track groove 30. Since there is no space inside the third section 29 of the inner track groove 30, the lock gate 10 cannot be pushed out under the action of other external forces, that is, one end of the steel cable 4 is completely locked by the lock gate 10. At this time, the steel cable gate 19 is squeezed out by the outer track edge 25 of the track turntable 5, and the clamping section on the steel cable gate 19 slides into the two second slots 24. At this time, the steel cable 4 in the long through hole 9 is locked.

[0048] The locking part also includes a lock shell 3, which is buckled on the side of the bracket 6 away from the lock head, and the locking action member is located in the lock shell 3. Three through holes are opened on the side wall of the lock shell 3, two of which are used for the middle part of the steel cable 4 to pass into and out of the lock shell 3, and the other through hole is used for one end of the steel cable 4 to pass into the lock shell 3, and the lock shell 3 plays a packaging role.

[0049] One end of the rotating shaft of the lock head is a special-shaped shaft 7, which can be inserted into the special-shaped hole 26 and connected with the special-shaped hole 26 in a limiting position, so that the track turntable 5 can be driven to rotate stably by the special-shaped shaft 7.

[0050] The lock head adopts a traditional password lock head, specifically including a handwheel 1 housing and a password locking part. A bracket 6 is located on the outer periphery of the password locking part. The handwheel 1 housing covers the outer periphery of the bracket 6. The password locking part is connected to the handwheel 1 housing, and the password wheel 2 of the password locking part extends out of the handwheel 1 housing. When the password wheel 2 of the password locking part is toggled and the correct password is entered, the bracket 6 does not limit the password locking part. At this time, rotating the handwheel 1 can drive the password locking part to rotate relative to the bracket 6, and the rotating shaft of the password locking part drives the locking part to rotate. When the password wheel 2 of the password locking part is toggled and the wrong password is entered, at this time the bracket 6 limits the password locking part and the handwheel 1 cannot rotate. Preferably, the password locking part is a three-digit password lock. The specific principle of the lock head is the same as that of the prior art and will not be elaborated here.

[0051] In the present invention, specific examples are used to illustrate the principle and implementation manner of the present invention. The description of the above embodiments is only used to help understand the method and its core idea of the present invention; at the same time, for those of ordinary skill in the art, according to the idea of the present invention, there will be changes in the specific implementation manner and application scope. In summary, the content of this specification should not be construed as a limitation to the present invention.
