[0002] A steering wheel lock is a security device used to prevent car theft. It is usually installed on the steering wheel of a vehicle and prevents the vehicle from moving by physically locking the steering wheel so that it cannot be turned.

[0003] For example, the Chinese invention patent with publication number CN1405039A discloses a foldable steering wheel lock, including a lock tube, a folding tube and a lock cylinder; the inner end of the lock tube is connected to a folding tube by a hinge, the outer end of the lock tube opposite to the folding tube is provided with a hoop hook, and a lock seat is provided near the connection between the lock tube and the folding tube. Among them, although the folding tube and the shrinking tube can be folded in half, the volume is still large, which is inconvenient to store and easily causes danger to vehicle passengers. In addition, the existing steering wheel lock usually uses a key to unlock, and the key needs to be pressed and twisted to unlock, which is inconvenient to unlock, and the key is easy to be lost, causing inconvenience to the car owner. Summary of the invention

[0004] The utility model aims at the shortcomings of the prior art and provides a buckle-type steering wheel password lock which is convenient, easy to unlock and easy to store.

[0005] To solve the above technical problems, the utility model is solved through the following technical solutions: a buckle-type steering wheel password lock, comprising a surrounding rope and a password lock buckle; the surrounding rope comprises a connecting part and a sleeve ring part, both ends of the surrounding rope are connecting parts, and the connecting part is fixedly connected with the password lock to form the sleeve ring part; the password lock buckle comprises a sub-buckle, a lock body shell and a lock body, the sub-buckle comprises a mounting part and a tongue that is snap-connected with the seat belt mother buckle, and the mounting part and the tongue are arranged on both sides of the bottom plate; the lock body shell is provided with an operation window and a cavity that can accommodate the sub-buckle; the lock body is arranged on the mounting part, and comprises a digital wheel for unlocking and a locking core rod that can push the seat belt mother buckle switch, the digital wheel is sleeved on the locking core rod, and the locking core rod extends out of the lock body shell, and when the digital wheel is in the unlocked state, the locking core rod can move axially.

[0006] The safety belt buckle is an essential device for cars and is fixed in the car. The combination lock of the utility model passes through the sleeve ring part, so that the surrounding rope is wrapped around the steering wheel, and then the sub-buckle is engaged with the safety belt buckle to complete the locking of the steering wheel. When the steering wheel is in the locked state, the lock body shell covers the safety buckle switch, so that it cannot be opened by other means, forming a closed loop. When the steering wheel needs to be unlocked, by turning the number wheel to the correct number, the locking core rod can move axially, thereby pushing the safety buckle switch to release the closed loop, which is convenient to unlock and does not require carrying a key, which is more convenient. In addition, the surrounding rope is small in size and easy to fold and store.

[0007] Preferably, the number wheel also includes a plurality of number dials and a floating locking ring; the number dial has a limiting convex tooth on its inner circumference; the floating locking ring has a chimeric convex tooth on its outer circumference that cooperates with the limiting convex tooth, and the floating locking ring has a first groove on its inner circumference. When the first grooves are all on the same straight line, the first groove forms an unlocking channel for the axial movement of the locking core rod. The number dial is linked to the floating locking ring, and the password is correct, so that the first grooves are on the same straight line to form an unlocking channel, and the locking core rod can move axially to release the closed loop. When the password is wrong, the first groove cannot form an unlocking channel, hindering the movement of the locking core rod and maintaining the locked state.

[0008] Furthermore, the locking core rod is axially provided with a plurality of locking protrusions, and the locking protrusions move in the unlocking channel. When the locking protrusions and the first grooves are in the same straight line, the locking protrusions can be pushed through the first grooves, and when the first grooves are not in the same straight line, the blocking portion blocks the locking protrusions from moving.

[0009] In addition, the bottom plate has a plug-in hole for the plug-in to drive the floating locking ring to move; the mounting portion has a support block for supporting the floating locking ring, and the support block has a second groove for the engaging convex teeth to pass through. When the number wheel is in the decryption state, the second grooves are all on the same straight line, and the floating locking ring is moved by external force, and the linkage between the number dial and the floating locking ring is released, which is convenient for resetting the password.

[0010] Furthermore, the top of the mounting portion is provided with a spring stopper, and the spring stopper has a lock reset spring in contact with the starting floating lock ring. After the password is reset, the lock reset spring resets the displaced floating lock ring, so that the engaging convex teeth and the limit convex teeth resume the meshing state for normal use.

[0011] Furthermore, the number dial has a groove for separating numbers, and the number dial is equipped with a tactile spring sheet, which contacts the groove. The tactile spring sheet provides tactile feedback, and at the same time, the tactile spring sheet acts in the groove to increase resistance and avoid accidental touching of the number dial.

[0012] Preferably, the sleeve ring is wrapped with a bendable protective body, which is wrapped around the outer side of the surrounding rope to avoid abrasion to the steering wheel. BRIEF DESCRIPTION OF THE DRAWINGS

In addition, the sleeve ring portion 12 is wrapped with a bendable protective body 101, which is made of rubber to prevent the sleeve ring portion 12 from hard contact with the steering wheel, causing the steering wheel to wear and affect the appearance. The password lock includes a sub-buckle 2, a lock body shell 3 and a lock body 4; the sub-buckle 2 includes a mounting portion 21 and a latch tongue 22 that is snap-connected with the seat belt buckle. The latch tongue 22 is compatible with the seat belt buckle. The seat belt buckle is a necessary device for every car. It cooperates with the buckle on the seat belt to form a closed loop for the driver and passengers to protect the safety of the driver and passengers. Therefore, the seat belt buckle must have a certain strength. The sub-buckle 2 is inserted on the bottom plate 5, and the mounting portion 21 and the latch tongue 22 are arranged on both sides of the bottom plate 5. Figure 2 The lock housing 3 is provided with an operation window 31 and a cavity 32 for accommodating the sub-button 2. The lock body 4 is arranged on the mounting portion 21. Figure 3 and Figure 4 The lock body 4 includes a number wheel for unlocking and a locking core rod 43 that can push the seat belt buckle switch. The number wheel is sleeved on the locking core rod 43. The number wheel is moved through the operation window 31. The locking core rod 43 extends out of the lock body shell 3. When the number wheel is in the unlocked state, the locking core rod 43 can move axially. The locking core rod 43 can be equipped with a core rod reset spring 432 to reset the locking core rod 43. The number wheel also includes a plurality of number dials 41 and a floating locking ring 42. The floating locking ring 42 is linked to the number dial 41, wherein the inner circumference of the number dial 41 is provided with a limiting convex tooth 411, and the outer circumference of the floating locking ring 42 is provided with an engaging convex tooth 421 that cooperates with the limiting convex tooth 411.

When the password needs to be reset, the plug-in can be manually inserted into the socket 51, or the plug-in can be directly set in the socket 51. The plug-in is reset by providing a first spring, and the plug-in drives the floating locking ring 42 to pass through the second groove 61, so that the floating locking ring 42 and the digital dial ring 41 are decoupled. Specifically, a spring limit block 7 is provided at the top of the mounting portion 21, and a locking reset spring 8 is provided inside the spring limit block 7 and abuts against the starting floating locking circle 42. The locking reset spring 8 is sleeved on the locking core rod 43. When resetting the password, the plug-in pushes the floating locking circle 42, and the locking reset spring 8 is in a compressed state. After the password is reset, the plug-in no longer applies thrust, and the elastic force of the locking reset spring 8 resets the floating locking circle 42, so that the floating locking circle 42 and the digital dial circle 41 are restored to be linked.

[0025] refer to Figure 6 In order to prevent the lock body 4 from being locked by the accidental number wheel, the number dial 41 has a groove 9 for separating numbers, and the number dial 41 is equipped with a tactile spring 10, which contacts the groove 9. The groove 9 is arranged on the outer surface of the number dial 41. One end of the tactile spring 10 is fixedly arranged on the mounting portion 21, and the other end contacts the groove 9, so as to apply resistance to the number dial 41, and the tactile spring 10 can provide tactile feedback.

[0026] The working principle of the utility model is described below in conjunction with the accompanying drawings: when locking the steering wheel, the end of the sleeve ring 12 or the password lock buckle is passed through the steering wheel, and then the password lock buckle is passed through the sleeve ring 12, and then the sub-buckle 2 is connected to the seat belt mother buckle to form a closed loop, and the lock body shell 3 wraps the seat belt mother buckle in its cavity 32 to further ensure its safety. When unlocking the steering wheel, the number dial 41 is dialed to the correct number through the operation window 31. During the dialing process, the tactile spring 10 provides tactile feedback. At the same time, the number dial 41 and the floating locking ring 42 are linked to make the first grooves 422 all in a straight line to form an unlocking channel (that is, the number wheel is in an unlocked state), and the locking core rod 43 is pushed, so that the locking protrusion 431 on the locking core rod 43 passes through the unlocking channel, thereby pushing the seat belt mother buckle to release the closed loop and complete the unlocking.

[0027] When the password needs to be reset, the number wheel should be in the unlocked state, and the plug-in is inserted into the jack 51. The plug-in drives the floating locking ring 42 to release the linkage with the number dial ring 41 (that is, the engaging protruding tooth 421 is disconnected from the limiting protruding tooth 411), and the engaging protruding tooth 421 moves to the second groove 61. The number dial ring 41 is moved to the required number through the operation window 31, and then the plug-in is withdrawn, the locking reset spring 8 resets the floating locking ring 42, and the floating locking ring 42 and the number dial ring 41 resume linkage.
