[0044] Example 1

[0045] As Figures 1 to 11As shown, in an embodiment, a lock rope intelligent lock body includes a shell 1 and a locking mechanism located in the shell 1, the shell 1 is provided with a lock hole 2 through which one end of the lock rope can pass into the shell 1, the locking mechanism is located in the shell 1 and close to the lock hole 2 for locking the lock rope, the locking mechanism includes a fixed block 3 limited in the shell 1, a moving element 4 movably arranged on the fixed block 3, a clamping element 422 located in the fixed block 3, the moving element 4 and the clamping element 422 move along a first direction A1 and a second direction A2 opposite to the first direction A1,

[0046] The clamping element 422 is subjected to a continuous force in the first direction A1, the lock rope can be introduced into the clamping element 422 along the second direction A2, the clamping element 422 forms a locking fit with the inner inclined surface of the fixed block 3 and the lock rope under the action of the continuous force, and prevents the movement of the lock rope in the second direction A2,

[0047] The locking mechanism is provided with a first limiting element 7 on one side, the first limiting element 7 has a first locking position for limiting the movement of the moving element 4 to the second direction A2 and a first unlocking position for releasing the limitation.

[0048] By limiting the moving element by the first limiting element, the problem that the existing lock rope intelligent lock body structure can be pulled out by a third party tool from the gap between the lock rope and the shaft hole to make the front end of the moving element retreat a certain distance in the locking state is effectively solved, and the anti-theft ability and safety of the safe lock are greatly improved.

[0049] A first spring 5 is arranged between the inner wall of the shell 1 and the moving element 4, which abuts against the moving element 4 and has a continuous elastic force acting on the moving element 4.

[0050] The locking mechanism is provided with a drive mechanism 6 limited in the shell 1 on one side, in the embodiment, the drive mechanism 6 is a motor, the first limiting element 7 is connected to the drive end of the motor, and the first limiting element 7 is switched between the first locking position and the first unlocking position under the drive of the motor.

[0051] The moving element 4 is provided with a first limiting structure 411, the limiting structure 411 has a groove or an abutting surface, when the first limiting element 7 is in the first locking position, the first limiting element 7 is at least partially located in the groove of the first limiting structure 411 or abuts against the abutting surface of the first limiting structure 411 to limit the movement of the moving element 4 to the second direction A2.

[0052] The shell 1 is provided with an unlocking mechanism for unlocking the locking mechanism near the locking rope. The unlocking mechanism includes a button slider 8 and a second spring 9. The button slider 8 is subjected to a continuous elastic force of the second spring 9 in a third direction B1 perpendicular to the first direction A1. The end of the moving element 4 near the unlocking mechanism is an abutting portion 41 which penetrates the fixed block 3. The button slider 8 is located on the side of the abutting portion 41 of the moving element 4. The side of the button slider 8 near the abutting portion 41 is provided with a first inclined surface 821. Pushing the button slider 8 in the third direction B1 moves the first inclined surface 821 and abuts against the end of the moving element 4 to generate a force for pushing the moving element 4 to move in the second direction A2.

[0053] The driving end of the driving mechanism is further connected with a second limiting element 611. The side of the button slider 8 near the second limiting element 611 is correspondingly provided with a second limiting structure 823 having a groove or an abutting surface. The second limiting element 611 rotates under the driving of the driving mechanism 6 to have at least a part located in the groove of the second limiting structure 823 or abutting against the abutting surface on the side of the second limiting structure 823 near the third direction B1 to limit the second locking position of the button slider 8. The cooperation of the second limiting element and the second limiting structure can realize the second relocking of the lock body and further improve the safety of the device on the basis of the first limiting element.

[0054] The output end of the motor is sleeved with a fixed ring 61. The first limiting element 7 is a tab-shaped element with the bottom connected to the side wall of the fixed ring 61. The top of the fixed ring 61 is eccentrically provided with the second limiting element 611. The side of the button slider 8 near the second limiting element 611 is provided with a first recess 822. The bottom surface of the first recess 822 forms a first platform surface 8221. The bottom of the first recess 822 is provided with a second limiting structure 823 corresponding to the position of the second limiting element 611, i.e. a limiting groove. The second limiting element 611 rotates forward or reversely under the driving of the motor to have a second locking position located in the second limiting structure 823 and limiting the movement of the button slider 8 and a second unlocking position completely separated from the second limiting structure 823.

[0055] The first limiting element 7 and the second limiting element 611 are state-synchronized. When the second limiting element 611 is in the second unlocking position, the first limiting element 7 is in the first unlocking position. When the second limiting element 611 is in the second locking position, the first limiting element 7 is in the first locking position. Through the above arrangement, the state switching of the two limiting elements is controlled by the same power output end at the same time, ensuring the synchronization of the two. Not only is the unlocking process simplified, but also the layout of the elements inside the shell is simplified, improving the utilization rate of the limited space and enabling the lock body to maintain a small size and be flexibly applied to various life and production scenes.

[0056] The second limiting element 611 is a fan-shaped second limiting element, and a side close to the center of the motor output end has a first tangent surface 6111 and a second tangent surface 6112. When the second limiting element 611 is in the second locking position, the first tangent surface 6111 faces the side wall of the second limiting structure 823, and the second tangent surface 6112 faces the internal corner of the second limiting structure 823. Through the above setting, the corner collision and wear in the rotation process can be avoided, and the utilization of the internal space of the shell is further improved.

[0057] The button slider 8 is provided with a waist-shaped hole 812 through which the lock rope passes, and the waist-shaped hole 812 extends in the third direction B1 and the opposite direction thereof. The center through hole of the moving element 4 always corresponds to the position of the waist-shaped hole 812, and the width of the waist-shaped hole 812 is smaller than the size of the abutting portion, so that abutting and pushing can be realized.

[0058] The button slider 8 includes a button portion 81 and a slider portion 82 connected with each other. The button portion 81 is located at one end of the slider portion 82 away from the second spring 9 and penetrates out of the shell 1, so as to facilitate the operation of the unlocking action.

[0059] The slider portion 82 has a first slider portion and a second slider portion with gradually increasing thickness in sequence from the second spring 9 to the button portion 81, and the first abutting surface 821 is formed on the side wall of the second slider portion. The first abutting surface 821 is an arc-shaped convex surface, so that the abutting and pushing of the abutting portion are more stable.

[0060] The button slider is arranged in consideration of both the perforation and unlocking requirements. By forming an abutting surface on the side of the button slider to push, compared with other structures such as protrusions, the processing is convenient, and the space utilization inside the shell is further simplified.

[0061] The moving element 4 is an integral molding, and has a first limiting surface limiting the movement of the clamping element 422 in the second direction A2 and a second limiting surface limiting the movement of the clamping element 422 in the first direction A1. Compared with a split type or a first limiting surface arranged on a fixed block, the structure is more convenient to assemble and the connection is more stable.

[0062] The moving element 4 has an abutting portion 41, a first taper portion 42 and a second column portion 43 connected in sequence in the first direction A1. The first taper portion 42 increases in size in the second direction A2, and the first taper portion 42 is provided with a plurality of slotted holes 421 in the circumferential direction and communicated with the center through hole of the moving element 4.

[0063] The fixed block 3 is provided with a mounting channel, one end of which is a first through hole 31 matched with the size of the abutting portion 41, and the other end is a second through hole 32 matched with the size of the second column portion 43, the first through hole 31 is smaller than the second through hole 32, the mounting channel further comprises a first tapered hole 33 connecting the first through hole 31 and the second through hole 32,

[0064] The first tapered hole 33 has a gap between the abutting portion 41 and the first tapered portion 42, and the gap gradually decreases in the first direction A1,

[0065] The clamping element 422 is a steel ball, and a steel ball is arranged between the first tapered hole 33 and each slot 421, when the moving element 4 is in the first locking position, the steel ball, the tapered surface formed by the first tapered hole 33 and the inner wall of the fixed block 3, and the locking rope are locked together under the continuous force in the second direction A2. In this embodiment, the slot is a square slot, there are three slots, and the slots are arranged in the radial direction.

[0066] The moving element 4 is provided with a third column portion 44 near one end of the first spring 5, the shaft hole extends to and penetrates the center of the third column portion 44, the third column portion 44 is smaller than the second column portion 43, and one end of the first spring 5 is sleeved outside the third column portion 44 and limited to the bottom of the second column portion 43;

[0067] The button slider 8 is provided with a spring mounting groove 83 near one end of the second spring 9, and one end of the button slider 8 is limited in the spring mounting groove 83. Through the above setting, the stability of the spring connection is improved.

[0068] The housing 1 is provided with a detection switch 10 for detecting the arrival of the first limiting element 7. The detection switch is located at the bottom of the first limiting element 7, the detection switch 10 is fixed on the positioning plate 11, two first side plates 12 are arranged in parallel on the side wall of the housing near the first limiting element 7, and the positioning plate 11 penetrates the bottom of the unlocking mechanism and is inserted between the two first side plates 12.

[0069] The driving end of the driving mechanism is further provided with a to-position detection protrusion 612 located on the fixed ring 61 on the side different from the first limiting element 7. The detection switch 10 has a first detection contact 101 and a second detection contact 102, both of which are located on the positioning plate 11 on the side close to the driving mechanism. The first detection contact 101 confirms the first limiting element 7 is located at the first locking position by detecting the to-position of the first limiting element 7. The second detection contact 102 confirms the first limiting element 7 is located at the first unlocking position by detecting the to-position of the to-position detection protrusion 612. The detection switch can detect whether the first limiting element driven by the motor normally locks or unlocks, and has a certain limiting effect on the first limiting element. Through this structure, the intelligent lock can be monitored in real time to determine whether it is in an open state or a closed state. The double detection contacts have higher accuracy. In this embodiment, the detection switch is specifically a to-position contact detection switch.

[0070] The inner cavity side wall of the shell 1 and the motor 6 have a containing cavity 16 for placing a battery 17. Due to the simplified internal structure of the device, a 3500mA battery with larger capacity can be selected.

[0071] The shell 1 is provided with a fixed hole 19 for the fixed end of the lock rope to pass through and be fixed. The side of the containing cavity 16 close to the fixed hole 19 is provided with a chamfer 161, which facilitates the operation of the staff when replacing the lock rope.

[0072] The side wall of the shell 1 close to the first spring 5 is provided with two second side plates 13 in parallel. The two second side plates 13 have a spacing therebetween. The side plate 13 close to the containing cavity 16 forms a wiring groove 18 with the containing cavity 16. An L-shaped electrode sheet 14 is arranged between the first spring 5 and the second side plate 13. The L-shaped electrode sheet is an integrally formed piece composed of a first sheet part 141 and a second sheet part 142. The first sheet part 141 is located between the first spring 5 and the front ends of the two second side plates 13. The second sheet part 142 is located on the side close to the wiring groove 18. One end of the first spring 5 abuts against the first sheet part 141. Compared with the traditional single-stage iron sheet wiring which needs to pass through the upper end groove of the plastic shell and has the risk of being pressed by the upper cover, the single-pole iron sheet of the device is directly connected to the wiring groove in an L-shaped structure, and there is no risk of being pressed by the upper cover.

[0073] The lock body further comprises a rubber shell 15 sleeved on the shell 1. The rubber shell 15 is provided with an anti-theft hook 151. The hook can be used to fix the lock body and has a certain effect on anti-theft.

The central through hole of the moving element (4) always corresponds to the position of the waist-shaped hole (812).

4. The smart lock body with a rope lock according to claim 1, characterized in that: The moving element (4) has a contact part (41), a first cone part (42) and a second column part (43) connected in sequence along the first direction (A1). The size of the first cone part (42) increases along the second direction (A2). The first cone part (42) is provided with a plurality of slots (421) that communicate with the central through hole of the moving element (4) along the circumference. The fixing block (3) has an installation channel running through its center. One end of the installation channel near the unlocking mechanism is a first through hole (31) that matches the size of the abutment part (41), and the other end is a second through hole (32) that matches the size of the second column part (43). The size of the first through hole (31) is smaller than that of the second through hole (32). The installation channel also includes a first conical hole (33) that connects the first through hole (31) and the second through hole (32). There is a gap between the first conical hole (33) and the abutment portion (41) and the first conical portion (42), and the gap between it and the first conical portion (42) gradually decreases in the first direction (A1). The clamping element (422) is a steel ball. A steel ball is provided between the first conical hole (33) and each slot (421). When the moving element (4) is in the first locking position, under the action of the continuous force in the second direction (A2), the steel ball, the conical surface formed by the first conical hole (33) on the inner circumference of the fixed block (3) and the locking rope are locked together.

5. A smart lock body for rope locking according to any one of claims 1-4, characterized in that: The housing (1) is provided with a detection switch (10) for detecting the position of the first limiting element (7), and a position detection protrusion (612) is provided on the side of the drive end of the drive mechanism that is different from the first limiting element (7). The detection switch (10) has a first detection contact (101) and a second detection contact (102). The first detection contact (101) confirms that it is in the first locked position by detecting the first limiting element (7) in place. The second detection contact (102) confirms that the first limiting element (7) is in the first unlocked position by detecting the positioning detection protrusion (612) in place.
