One end of the cable 4 is locked at the same time, realizing double locking between the steel cable 4 and the locking part, and improving the locking effect. The track turntable 5 is provided with a guide rail on the side close to the locking part. The lock head can drive the track turntable 5 to rotate, and when the track 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 coordinating the guide rail with the locking part, and then when the locking part is used to lock the steel cable 4, the guide rail is limited to the locking part, ensuring that the lock gate 10 can be completely locked to prevent it from being unlocked by the paddle technology, thereby improving the anti-theft effect.

[0022] Specifically, the locking part includes a bracket 6 and a locking action piece. The bracket 6 serves as a supporting body and plays the role of an installation platform. The middle part of the steel cable 4 and one end of the steel cable 4 can pass through the bracket 6. The locking action piece can lock the middle part of the steel cable 4 and one end of the steel cable 4 on the bracket 6 to achieve fixing the steel cable 4 on the bracket 6, and then lock the bicycle or the like through the steel cable 4. The locking action piece 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 track turntable 5. When the rotating shaft of the lock head drives the track turntable 5 to rotate, the locking action piece can move with the rotation of the track turntable 5 to lock or unlock the steel cable 4.

[0023] The bracket 6 is provided with a long blind hole 8 and a long through hole 9 on one side for installing the locking action piece. 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 action piece 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 action piece can lock the middle part of the steel cable 4 in the long through hole 9 and one end of the steel cable 4 in the long blind hole 8 under the drive of the guide rail, and then limit one end of the steel cable 4 at the long blind hole 8 by the locking action piece, and limit the middle part of the steel cable 4 at the long through hole 9 by the locking action piece. When actually locking, it can lock both single and double circles, and can be freely switched according to user needs, so that users do not need to buy different locks repeatedly, thereby achieving the purpose of one lock for multiple uses.

[0024] A first slot 23 is provided in the middle of the long blind hole 8, and the first slot 23 is connected to the inside of the long blind hole 8. Two second slots 24 are provided in the middle of the long through hole 9, and the two second slots 24 are arranged along the length direction of the long through hole 9, and the second slots 24 are connected to the inside of the long through hole 9, so that the locking action member can lock the steel cable 4 at the first slot 23 and the second slot 24 respectively. The locking action member includes an end action member and a middle action member, both of which are movably mounted 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, and the end action member can be driven by the guide rail to move toward or away from one end of the steel cable 4 through the first slot 23. 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 24, the end of the steel cable 4 can be locked. When the middle action piece is at the slot 23, the end action piece no longer contacts one end of the steel cable 4, thereby unlocking one end of the steel cable 4. The middle action piece can move toward 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 piece 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 piece moves away from the second slot 24, the middle action piece no longer contacts the middle of the steel cable 4, thereby unlocking the middle of the steel cable 4.

[0025] The guide rail includes an outer rail edge 25 and an inner rail groove 30, wherein the outer rail edge 25 is used to cooperate with the middle action piece, and the inner rail groove 30 is used to cooperate with the end action piece.

[0026] The outer track edge 25 is arranged on the outer periphery of the track turntable 5, and 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, and a special-shaped hole 26 is provided in the middle of the track turntable 5, and the distance between the first end of the outer track edge 25 and the special-shaped hole 26 is smaller than the distance between the second end of the outer track edge 25 and the special-shaped hole 26, and the distance between the outer track edge 25 and the special-shaped hole 26 gradually increases from the first end of the outer track edge 25 to the second end of the outer track edge 25, and the driving end of the middle action member is located at the outer periphery of the track turntable 5, so that as the track turntable 5 rotates, the outer track edge 25 drives the middle action member to move in a straight line. The specific process is that when the track turntable 5 rotates along the first direction, the first end of the outer track edge 25 first contacts the driving end of the middle action member, and as the track turntable 5 continues to rotate, the outer track edge 25 The middle part and the second end of the track edge 25 gradually contact the driving end of the middle acting member, so that the driving end of the middle acting member and the middle acting member gradually move in the direction away from the special-shaped hole 26 of the track turntable 5, that is, gradually move in the direction close to the middle part of the steel cable 4, until the middle part of the steel cable 4 is locked at the second slot 24. When the track turntable 5 rotates along the second direction, the second end of the outer track edge 25 first contacts the driving end of the middle acting member. 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 acting member, so that the driving end of the middle acting member and the middle acting member gradually move in the direction close to the special-shaped hole 26 of the track turntable 5, that is, gradually move in the direction away from the middle part of the steel cable 4, until they are separated from the middle part of the steel cable 4, thereby unlocking the middle part of the steel cable 4, and the first direction is opposite to the second direction.

[0027] 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.

[0028] The middle action member includes a cable brake 19 and a spring leaf 20. A limiting protrusion 22 is provided on the outer edge of the bracket 6.

At this time, the spring plate 20 is deformed and stores energy, so that the subsequent spring plate 20 is reset and pushes the steel cable brake 19 to move in the direction close to the steel cable 4. The specific process is that when the track turntable 5 drives the outer track edge 25 to rotate, and the first end of the outer track edge 25 first contacts the middle cylindrical protrusion 21, at this time, the outer track edge 25 gradually bulges outward, thereby pushing the middle cylindrical protrusion 21 in the direction away from the middle of the steel cable 4. Move until the spring leaf 20 is pressed against one side of the limiting protrusion 22. At this time, the spring leaf 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 to achieve the locking of the steel cable 4. When the track turntable 5 drives the outer track edge 25 to rotate in the opposite direction, the outer track edge 25 gradually contacts the limit of the centering cylindrical protrusion 21. At this time, the spring leaf 20 can be reset in the direction away from the limiting protrusion 22, and drive the center cylindrical protrusion 21 to move toward the middle part of the steel cable 4 until the clamping section is separated from the middle part of the steel cable 4, thereby achieving unlocking.

The long column 16 that comes out of the limit long hole 17 can push the single-hole elastic member 15 to move towards or away from the locking column 18 as one end of the steel cable 4 is inserted into or leaves the long blind hole 8, thereby compressing or loosening the single-hole elastic member 15. In this process, the movement stroke of the long column 16 is the length of the limit 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 gate 10 locks one end of the steel cable 4. When the locking gate 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 to pop out of the long blind hole 8, realizing automatic pop-up and improving the sense of use; the track turntable 5 rotates to make the end cylinder When the protrusion 11 moves relatively in the first section 27, the inner edge of the first section 27 can push the end cylindrical protrusion 11 to move toward one end of the steel cable 4 until the arc groove 34 clamps the annular groove. At this time, the locking spring 14 gradually resets and extends. When the track turntable 5 rotates to make the end cylindrical protrusion 11 move relatively in the second section 28, the locking spring 14 can move back and forth in the air avoidance area. When the track turntable 5 rotates to make the end cylindrical protrusion 11 move relatively in the third section 29, the inner edge of the third section 29 can push the end cylindrical protrusion 11 to move toward one end of the steel cable 4 until the arc groove 34 clamps the annular groove. At this time, the locking spring 14 is in a reset and extended state.

[0030] Through the above design, the cable lock in this embodiment can achieve three states, namely, unlocked state, rebound locked state and locked state, wherein: 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. 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.

[0031] 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.

[0032] 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.

[0033] 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.

[0034] The lock adopts a traditional password lock, specifically including a handwheel 1 shell and a password locking part, a bracket 6 is located at the periphery of the password locking part, a handwheel 1 shell is covered on the periphery of the bracket 6, the password locking part is connected to the handwheel 1 shell, and the password wheel 2 of the password locking part extends out of the handwheel 1 shell. When the password wheel 2 of the password locking part is turned 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 turned and an incorrect password is entered, 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 is consistent with the prior art and will not be repeated here.

[0035] The present invention uses specific examples to illustrate the principles and implementation methods of the present invention. The above examples are only used to help understand the method and core ideas of the present invention. At the same time, for those skilled in the art, according to the ideas of the present invention, there will be changes in the specific implementation methods and application scope. In summary, the content of this specification should not be understood as limiting the present invention.
