[0054] Specifically, the second insertion hole 25 is a circular threaded hole, the fastener 52 is in a circular tube shape, and the outer surface of the fastener 52 has threads, and the fastener 52 is connected to the second insertion hole 25 through threaded matching.

[0055] The elastic telescopic member 51 includes a latch 510, a spring 514 and a buckle 515. The latch 510 includes a first latch section 511 and a second latch section 512 which are connected and located on the same straight line, and the cross-sectional area of ​​the first latch section 511 is larger than the cross-sectional area of ​​the second latch section 512. The spring 514 is sleeved on the second latch section 512. The second latch section 512 has a connecting hole 513 at one end away from the first latch section 511, and the buckle 515 is fixedly connected to the connecting hole 513.

[0056] The internal hollow space of the fastener 52 forms a first through hole 521 and a second through hole 522 located on the same straight line, the first through hole 521 is located between the second through hole 522 and the first plug hole 44, the cross-sectional area of ​​the first through hole 521 is larger than the cross-sectional area of ​​the second through hole 522 and the cross-sectional area of ​​the first latch segment 511, the cross-sectional area of ​​the second through hole 522 is smaller than the cross-sectional area of ​​the first latch segment 511, and larger than the cross-sectional area of ​​the second latch segment 512; the second latch segment 512 cooperates with the second through hole 522, and the first latch segment 511 cooperates with the first through hole 521.

[0057] Combination Fig. 9 and Fig.12 As shown, in the embodiment of the present application, a slide groove 45 is further provided on the first plate body 411 and the second plate body 412. Along the length direction of the slide groove 45, the first end of the slide groove 45 is connected with the first plug hole 44, and the second end of the slide groove 45 passes through the connecting arm 40; moreover, from the first end of the slide groove 45 to the second end of the slide groove 45, the depth of the slide groove 45 gradually increases, and the width of the slide groove 45 also gradually increases; wherein, the length direction of the slide groove 45 is the tangent direction of the rotation trajectory of the connecting arm 40 around the fixed base (it can also be understood as the thickness direction of the fixed arm 41). By providing the slide groove 45 below the first insertion hole 44, when the lock buckle enters the locked state, there is no need to pull the pull buckle 515, and only needs to press the fixed arm 41. At this time, the side wall of the slide groove 45 abuts against the movable latch 510. As the fixed arm 41 gradually descends, the slide groove 45 also moves downward, gradually increasing the squeezing force on the latch 510, and finally the latch 510 is inserted into the first insertion hole 44. This process does not require contact with the locking assembly 50, and there is no need to pull the pull buckle 515 all the time, which is convenient to use.

[0058] Fig.13 This is an exploded diagram of the lock, combined with Figure 1 and Fig.13As shown, when the pull buckle 515 is pulled outward, the pull buckle 515 drives the pin 510 to move outward and squeezes the spring 514 until the first pin section 511 abuts against the inner wall of the second through hole 522. At this time, the contracted pin 510 is sufficient to make the first pin section 511 withdrawn from the first insertion hole 44. At this time, the rotation of the fixed arm 41 is not restricted by the locking assembly 50. The fixed arm 41 can be lifted first, and then the movable arm 42 can be rotated to disengage the hook 43 from the locking position 33. At this time, the lock buckle 10 is in an unlocked state. When the lock buckle 10 needs to be locked, first rotate the movable arm 42 to engage the hook 43 with the said bite, and then press the fixed arm 41 so that the fixed arm 41 is in contact with the pad 24. At this time, the first socket 44 on the fixed arm 41 is just aligned with the second socket 25 on the first fixed base 20, and the pin 510 is automatically inserted into the first socket 44 under the action of the spring 514, completing the locking of the fixed arm 41, so that the lock buckle 10 is in a locked state.

[0059] In the embodiment of the present application, the buckle 515 is a ring-shaped keychain, and the keychain is connected to the connecting hole 513, which makes it easy to pull out the latch 510, saves more effort, and facilitates the assembly of the locking assembly 50. Of course, in other embodiments, the buckle 515 can also be a rod-shaped structure, a hook-shaped structure, etc.

[0060] In the embodiment of the present application, the locking assembly 50 further includes a nut 53, which is sleeved on the fastener 52 and threadedly connected with the fastener 52. The nut 53 can be rotated on the fastener 52, and by adjusting the position of the nut 53, the length of the fastener 52 extending into the second insertion hole 25 can be controlled, and the length of the latch 510 extending into the first insertion hole 44 can be controlled, and the stability of the connection between the fastener 52 and the first fixed base 20 can be improved.

[0061] In the embodiment of the present application, the number of the locking assembly 50 is one, but the number of the first plug holes 44 is two, and the number of the second plug holes 25 is also two. At this time, according to the usage, the locking assembly 50 can be selected to be installed on different sides of the first fixed base 20. However, in other embodiments, there can also be two locking assemblies 50, and both sides of the first fixed base 20 have locking assemblies 50, so as to further improve the strength of locking the connecting arm 40.

[0062] In other implementations, the connecting arm 40 can be an integral body.

[0063] In other implementations, the fastener 52 may not be inserted into the second insertion hole 25 and threadedly engaged with the second insertion hole 25, but may be fixed on the outside of the first fixed base 20; and the fastener 52 may not be in a round tube shape.

[0064] In other implementations, the latch 510 and the buckle 515 can be an integral structure, and even the elastic telescopic member 51 can be an integral structure.

[0065] The embodiment of the present application fixes the first fixed base 20 and the second fixed base 30 on the two components, and connects the two components together by cooperating the hook 43 in the connecting arm 40 with the latch position 33 in the second fixed base 30; moreover, the lock buckle 10 in the embodiment of the present application also has a locking assembly 50. When using the lock buckle 10, it is only necessary to pull the elastic telescopic member 51 in the locking assembly 50. After pulling the elastic telescopic member 51, the elastic telescopic member 51 disengages from the first socket 44 in the connecting arm 40. At this time, the connecting arm 40 can be rotated to disengage the hook 43 from the latch position 33. At this time, the two components connected by the lock buckle 10 are disconnected; if the connection relationship between the two components is to be restored, it is only necessary to rotate the connecting arm 40 so that the hook 43 cooperates with the latch position 33, and then release the elastic telescopic member 51. At this time, the elastic telescopic member 51 is reset and inserted into the first socket 44, and the lock buckle 10 is in a locked state. Since the lock buckle 10 requires few operating steps and applies little force during the entire use process, it is very simple and convenient to use; in addition, the entire lock buckle 10 has a simple structure and is easy to manufacture, which is conducive to reducing costs.

[0066] The above content is a further detailed description of the present application in combination with specific optional implementation methods, and it cannot be determined that the specific implementation of the present application is limited to these descriptions. For ordinary technicians in the technical field to which the present application belongs, several simple deductions or substitutions can be made without departing from the concept of the present application, which should be deemed to fall within the scope of protection of the present application.
