[0040] The following will clearly and completely describe the technical solutions in the embodiments of the present invention with reference to 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. All other embodiments obtained by those of ordinary skill in the art based on the embodiments of the present invention without making creative efforts belong to the scope of protection of the present invention.

[0041] 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 with reference to the drawings and specific implementation manners.

[0042] The following will be combined with Figures 1 to 13 , to describe the embodiments of the present invention.

[0043] Embodiment 1

[0044] The present invention provides an indirectly locked password lock, as shown in Figure 1 , Figure 2 and Figure 7 , including: a lock body 1 and a lock rope 2. A jack 16 is constructed on the lock body 1; one end of the lock rope 2 is constructed with a plug 22, and the other end is constructed with a loop 21. The maximum cross-sectional dimension of the plug 22 is smaller than the minimum cross-sectional dimension of the loop 21, and the maximum cross-sectional dimension of the lock body 1 is larger than the minimum cross-sectional dimension of the loop 21; the plug 22 can be inserted into the jack 16, and the lock body 1 can lock and unlock the plug 22 in the jack 16. It can be understood that since the present invention provides a mechanical password lock, the lock body 1 has the function of unlocking the plug 22 only after inputting the password.

[0045] Usage method: Surround the object to be locked with the lock rope 2; pass the plug 22 from one side of the loop 21 to the other side; insert the plug 22 into the lock body 1; use the lock body 1 to lock the plug 22 in the jack 16. In order to enable the lock rope 2 to pass from one side of the loop 21 to the other side, the lock rope 2 needs to have the ability to bend. In this way, the plug 22 can be passed from one side of the loop 21 to the other side, and the lock rope 2 with the ability to bend can adapt to more scenarios.

[0046] The present invention can achieve the purpose of locking the object to be locked by means of the detachable lock rope 2 and the lock body 1, and is applicable to many usage scenarios, and is convenient and flexible to use. In addition, since the lock rope 2 and the lock body 1 are detachable, the lock rope 2 and the lock body 1 can be replaced with accessories separately. For example, the lock rope 2 can be configured with multiple different lengths to adapt to different scenarios, for example, one each of 20 cm, 30 cm, 50 cm, and 100 cm. In addition, when one component of the lock rope 2 and the lock body 1 is damaged, it is convenient to replace the component separately.

[0047] For example, the lock rope 2 can be passed through the wheel hub to lock the wheel, and electric vehicles, bicycles, etc. can also be locked on poles or some pillars. In addition, it can also be used on doors with door handles that open in opposite directions.

[0048] In some embodiments, the locking rope 2 is a steel cable or a chain.

[0049] The steel cables or chains in this embodiment have certain bending ability, good strength and high stability.

[0050] In some embodiments, such as Figures 4 to 7 As shown, the lock body 1 includes a shell component 11, a password handwheel component and a lock gate 12; one end of the shell component 11 is provided with a socket 16, and the other end is open, part of the password handwheel component is assembled in the shell component 11, and the remaining part of the password handwheel component is located on the outside of the open end of the shell component 11, the password handwheel component can be locked with the shell component 11 and limit the relative rotational freedom of the two; the password handwheel component can also be unlocked from the shell component 11 so that the password handwheel component and the shell component 11 can rotate relative to each other under the action of an external force, the password handwheel component and the lock gate 12 are connected by a lock tongue 13, the lock gate 12 is only movably arranged in the shell component 11 along a first straight line direction, and when the password handwheel component rotates, the lock gate 12 can be driven to move along the first straight line direction through the lock tongue 13, and the lock gate 12 is provided with a lock tongue 13 along the first straight line direction. The plug 22 is provided with a special-shaped hole 121 extending therefrom, one end of the special-shaped hole 121 being a large end 1211 and the other end being a small end 1212. The plug 22 is sequentially constructed with a limiting portion 222 and a shrinking neck portion 221 from the end thereof in a direction away from the end thereof. The cross-sectional dimension of the shrinking neck portion 221 is smaller than that of the limiting portion 222, the cross-sectional dimension of the shrinking neck portion 221 is smaller than that of the small end 1212, the cross-sectional dimension of the limiting portion 222 is larger than that of the small end 1212 but smaller than that of the large end 1211. The lock gate 12 has two states, one is an unlocked state and the other is a locked state. In the unlocked state, the large end 1211 of the special-shaped hole 121 is opposite to the insertion hole 16, and the plug 22 can be inserted from the large end 1211 of the special-shaped hole 121 to the shrinking neck portion 221 and is located in the special-shaped hole 121; in the locked state, the small end 1212 of the special-shaped hole 121 is opposite to the insertion hole 16.

[0051] The lock body 1 provided in this embodiment can achieve the purpose of locking and unlocking the plug 22.

[0052] Specifically, when in use, when locking is required, manually rotate the password handwheel assembly to drive the lock brake 12 to move along the first straight line direction until the large end 1211 of the special-shaped hole 121 faces the jack 16. Insert the plug 22 into the jack 16 so that the necking part 221 is located at the large end 1211 of the special-shaped hole 121. Manually rotate the password handwheel assembly to drive the lock brake 12 to move along the first straight line direction until the small end 1212 of the special-shaped hole 121 faces the jack 16. At this time, the necking part 221 is located at the small end 1212, and due to the small cross-sectional dimension at the lower end, the plug 22 cannot be pulled out of the jack 16 under the restricting action of the limiting part 222. Finally, scramble the password.

[0053] When unlocking is required, input the correct password, then rotate the password handwheel assembly to drive the lock brake 12 to move along the first straight line direction until the large end 1211 of the special-shaped hole 121 faces the jack 16, and then pull out the plug 22 from the jack 16.

[0054] In some embodiments, as Figure 6 shown, the lock tongue 13 includes a transmission disc 131 and a transmission column 132. One side of the transmission disc 131 cooperates with the password handwheel assembly so that the password handwheel assembly can drive the transmission disc 131 to rotate. The other side of the transmission disc 131 is eccentrically provided with a transmission column 132. A transmission hole 122 extending along a direction perpendicular to the first straight line is formed in the lock brake 12. The end of the transmission column 132 away from the transmission disc 131 is inserted into the transmission hole 122. The password handwheel assembly drives the transmission column 132 to rotate eccentrically, thereby driving the lock brake 12 to extend along the first straight line direction.

[0055] The lock tongue 13 provided in this embodiment has a simple structure and a simple mechanical principle.

[0056] In some embodiments, as Figures 10 to 13 shown, the embodiment of the present invention further includes an assembly bracket 3. The assembly bracket 3 is detachably connected to an external support body, and the lock body 1 is detachably connected to the assembly bracket 3.

[0057] The assembly bracket 3 in this embodiment can be installed on carriers such as vehicles. The carrier can be a bicycle, an electric vehicle, etc. For example, it is installed at the seat tube position of a bicycle to achieve the purpose of carrying the lock with the vehicle. And since the lock body 1 is detachably connected to the assembly bracket 3, the lock body 1 can also be detached from the assembly bracket 3 and used alone in cooperation with the lock rope 2.

[0058] In some embodiments, the embodiment of the present invention further includes an indirect fixing sleeve 4. The indirect fixing sleeve 4 is detachably sleeved outside the lock body 1. The indirect fixing sleeve 4 is detachably connected to the assembly bracket 3. Both sides of the indirect fixing sleeve 4 are configured with hollow portions 41. One end of the indirect fixing sleeve 4 is open, and the other end is provided with a through hole 42. When the indirect fixing sleeve 4 is sleeved outside the lock body 1, the through hole 42 is aligned with the jack 16.

[0059] In this embodiment, by adding the indirect fixing sleeve 4, the lock body 1 can be detachably connected to the assembly bracket 3. The lock body 1 and the indirect fixing sleeve 4 are connected in a sleeved manner, so that there is no additional structure outside the lock body 1 to cooperate with the assembly bracket 3. Therefore, when the lock body 1 is used alone, its appearance is still beautiful without an additional protruding structure 1412. Of course, in order to make the connection between the lock body 1 and the indirect fixing sleeve 4 more stable, a conventional snap structure can also be provided between the lock body 1 and the indirect fixing sleeve 4. After the lock body 1 is placed in the indirect fixing sleeve 4, the lock body 1 and the indirect fixing sleeve 4 are connected through the snap structure. Of course, the size of the part of the snap structure provided on the lock body 1 should be as small as possible to avoid excessive adverse effects on the appearance or feel of the lock body 1.

[0060] In addition, in order to prevent the indirect fixing sleeve 4 and the housing assembly 11 from slipping when the password handwheel assembly is rotated, hollow portions 41 are configured on both sides of the indirect fixing sleeve 4. The hollow portion 41 is specifically a hole. The user's finger can directly contact the outer wall of the housing assembly 11 through the hollow portion 41, and then the housing assembly 11 can be stopped by directly pinching the housing assembly 11.

[0061] In some embodiments, a chute 31 is configured on the assembly bracket 3. A first spring chamber 34 is configured on the inner wall of one side of the chute 31. A first spring 34 is arranged in the first spring chamber 34. A clamping member 32 is arranged in the chute 31. One end of the clamping member 32 is fixedly connected to one end of a pressure lever 33. The other end of the pressure lever 33 extends to one side of the assembly bracket 3. The pressure lever 33 is slidably connected to the assembly bracket 3. A sliding head 43 is configured outside the indirect fixing sleeve 4. The sliding head 43 can slide into the chute 31 from one end of the chute 31. A clamping groove 44 is arranged on the side of the sliding head 43 facing the clamping member 32. When the sliding head 43 is located in the chute 31 and the pressure lever 33 is not subject to external force, the clamping member 32 extends into the clamping groove 44 under the elastic force of the first spring 34 to limit the movement of the sliding head 43 in the chute 31. When the pressure lever 33 is subjected to a pressure towards the clamping member 32, the clamping member 32 can overcome the elastic force of the first spring 34 and move out of the clamping groove 44 to release the restriction on the movement freedom of the sliding head 43.

[0062] This embodiment realizes the detachable connection between the indirect fixing sleeve 4 and the assembly bracket 3.

[0063] In some embodiments, anti-slip patterns are provided on a part of the password handwheel assembly located outside the open end of the housing assembly.

[0064] This embodiment facilitates holding the outer part of the password handwheel assembly to apply torque to the password handwheel assembly for rotation.

[0065] Specifically, as Figure 4 shown, the password handwheel assembly includes a rotating assembly. The rotating assembly 15 includes a handwheel password rack 151 located inside the housing assembly 11 and a handwheel housing 152 located outside the housing assembly 11. The handwheel housing 152 and the handwheel password rack 151 are fixedly connected by two bolts so as to achieve the purpose that rotating the handwheel housing 152 can drive the handwheel password rack 151 to rotate. A structure for placing the password handwheel assembly is constructed on the handwheel password rack 151.

[0066] The password handwheel assembly further includes a handwheel assembly 14, which includes a positioning wheel push block 141, a password wheel 142, a central shaft 143, and a central shaft spring 144. One end of the positioning wheel push block 141 is configured with a triangular brake convex 1411. The housing assembly 11 includes a housing 111 and a handwheel card seat 112 disposed inside the housing 111. A first notch or a first groove that cooperates with the brake convex 1411 is provided along the handwheel card seat 112. After the brake convex 1411 extends into the first notch or the first groove, the circumferential positions of the handwheel card seat 112 and the password handwheel assembly are locked, and thus the password handwheel assembly cannot rotate relative to the handwheel card seat 112 (the handwheel card seat 112 is part of the housing assembly 11). There are three password wheels 142, and the circumferential outer walls of the three password wheels 142 are all configured with numbers 0-9. A second notch or a second groove is configured on the side of the password wheel 142 facing the brake convex 1411, and a protrusion 1412 that cooperates with the second notch or the second groove is configured on the positioning wheel push block 141. A central shaft 143 is provided in the middle of the password wheel 142, and the central shaft 143 can move along the axial direction of the password wheel 142. A limiting convex ring 1431 is configured at one end of the central shaft 143, and a central shaft spring 144 is sleeved on the central shaft 143. One end of the central shaft spring 144 contacts one side of the limiting convex ring 1431, and the other end contacts the password wheel 142, so that the axial position of the password wheel 142 does not change. The positioning wheel push block 141 can move along a direction parallel to the axial direction of the password wheel 142. A limiting platform 1413 that cooperates with the limiting convex ring 1431 is provided at the bottom of the positioning wheel push block 141, and the end of the limiting convex ring 1431 away from the central shaft spring 144 abuts against the limiting platform 1413. Under normal conditions, under the action of the elastic force of the central shaft spring 144, the positioning wheel push block 141 receives a force that moves towards the first notch or the first groove. Therefore, when the password handwheel assembly rotates in place, the positioning wheel push block 141 can move until the brake convex 1411 extends into the first notch or the first groove, and then by scrambling the password of the password wheel 142, the second notch or the second groove and the protrusion 1412 are displaced, so that the positioning wheel push block 141 cannot move away from the first notch or the first groove. When unlocking is required, that is, by rotating the password wheel 142 to the correct password, the second notch or the second groove is aligned with the protrusion 1412. At this time, when the password handwheel assembly is rotated, due to the triangular structure of the brake convex 1411, the brake convex 1411 can receive a component force that moves away from the first notch or the first groove, so that the brake convex 1411 can move out of the first notch or the first groove. At this time, the protrusion 1412 moves into the second notch or the second groove and completes the unlocking of the plug 22.

[0067] The above only provides an implementation manner of the password handwheel assembly. In actual application examples, the password handwheel assembly only needs to be able to achieve the functions of circumferentially limiting and releasing the limit on the housing assembly 11 and the password handwheel assembly. The present invention does not limit the specific structure of the password handwheel assembly.

[0068] In some embodiments, the contours of the large end 1211 and the small end 1212 of the special-shaped hole 121 are both arc-shaped, and the two ends of the contour of the large end 1211 are connected to the two ends of the contour of the small end 1212.
