[0002] The axle head is an important part of the automobile suspension system. It connects the wheels and the suspension system and plays the role of bearing the weight of the wheels and steering. For example, the trailer head hook configured on the trailer is used as the parking axle head. However, during the parking process, due to some special circumstances, there may be unauthorized suspension of the trailer head hook to tow the vehicle away. Therefore, in order to ensure the safety of the vehicle, a sleeve lock is generally installed on the trailer head hook to prevent the vehicle from being towed away or stolen.

[0003] The current sleeve lock is generally like Figure 1 As shown: it includes a sleeve 1a and a lock core assembly 2a, the sleeve 1a opens upward, the lock core assembly 2a is arranged on the side of the sleeve 1a, and its lock hole faces downward. In locking the parking shaft head 8a, the sleeve 1a is usually put on the parking shaft head 8a, and then the sleeve 1a is supported by one hand, and the key 21a is held in the other hand, and it is inserted into the lock hole from bottom to top, and rotated to open and lock. Although this sleeve lock has a simple structure, the downward unlocking method is more troublesome in terms of alignment and operation, especially when the parking shaft head 5a is at a low position, it is more difficult to insert the sleeve 1a, and the corresponding space below the lock hole is small, and it is impossible to align by observing the position of the lock hole, and the key is difficult to insert; the weight of the sleeve lock is usually heavy, and after the sleeve is put on, there is a lack of fixings between the sleeve 1a and the parking shaft head 8a, which causes the operator to operate with both hands to complete the locking of the sleeve lock. Utility Model Content

[0004] In view of this, the present application provides a snap-on parking sleeve lock, which can not only realize the visualization of the lock hole position, but also complete pre-positioning after being put on, thereby realizing one-handed operation.

When the sleeve 1 is mounted on the parking axle head 8, the inner wall of the parking axle head 8 squeezes the steel ball 7 to put it in a retracted state. When the parking axle head 8 falls to the height range where the through hole 711 enters the groove 81, the steel ball 7 is no longer squeezed and rebounds and protrudes. The steel ball 7 protrudes from the inner side of the through hole 711 and is buckled between the through hole 711 and the groove 81, completing the pre-positioning of the sleeve 1 and the parking axle head 8.

[0033] Preferred:

[0034] A base 71 can be set on the side wall of the sleeve 1, and a through hole 711 is set through the base 71 in a direction inclined or perpendicular to the sleeve 1. The steel ball 7 is first installed in the through hole 711, and then the spring 72 is installed. The two ends of the spring 72 can respectively contact the steel ball 7 and the base 71. The existence of the spring 72 realizes the elastic installation of the steel ball 7 in the through hole 711, and the three constitute a pre-positioning mechanism.

[0035] A hexagon socket head screw 73 may be installed at the outer end of the through hole 711 to fix the spring 72 in the through hole 711 . The elastic force of the spring 72 may also be adjusted by means of the hexagon socket head screw 73 .

[0036] A threaded hole 712 may also be provided on the base 71, into which a cross-slot pan head screw 75 is inserted, and a chain 74 is fixed to the base 71 by means of the cross-slot pan head screw 75, and a sign 76 is connected to the chain 74.

The second pin hole 241 is provided corresponding to the first pin hole 221, and the knurled pin 223 passes through the first pin hole 221 and penetrates into the second pin hole 241 to fix the lock sleeve 24 and the lock core seat 22; the lock core assembly 2 is installed in the lock sleeve 24 through the groove 242, and the lock core assembly 2 faces A lock hole corresponding to the key 21 is provided at one end of the outside, and a card block 25 is provided at the other end; a card groove 42 is provided at the end of the rotating sleeve 4 corresponding to the card block 25, and the card block 25 is immersed in the card groove 42 to realize the snap-fit ​​connection between the lock core assembly 2 and the rotating sleeve 4; a spiral groove 41 is provided on the side wall of the rotating sleeve 4; a third pin hole 51 is provided on the lock pin 5, and the two ends of the straight pin 3 are snapped in the sliding groove, which passes through the third pin hole 51 and the spiral groove 41 to connect the rotating sleeve 4 and the lock pin 5 together; an O-ring is provided on the side of the lock pin 5 close to the inner wall of the sleeve 1, which has the effect of sealing and waterproofing, and prevents rainwater from entering the rotating sleeve 4 through the sleeve 1 and soaking the lock core assembly 2.

[0038] When in use, sleeve 1 is put on the parking shaft head 8. Since the groove 81 is located at a certain height of the parking shaft head 8, when sleeve 1 is just put on the parking shaft head 8, due to the adaptation of the inner walls of the two, the steel ball 7 is squeezed and pushed into the channel 711 by the outer wall of the parking shaft head 8. Sleeve 1 is continuously put upward. When the through hole 711 falls into the coverage range of the groove 81, there is a certain gap between the outer wall of the groove 81 and the through hole 711. Under the deformation action of the spring 72, the steel ball 7 moves into the groove 81 along the through groove 711, and the sleeve 1 and the parking shaft head 8 are initially locked. At this time, the lock core assembly 2, the lock sleeve 24, the straight pin 3, the rotating sleeve 4 and the lock pin 5 are in a state of being locked.
