DETAILED DESCRIPTION
[0025] The present invention is further described below in conjunction with the accompanying drawings and specific implementation methods. It should be noted that, under the premise of no conflict, the various embodiments or technical features described below can be arbitrarily combined to form a new embodiment.
[0026] like Figure 1-5As shown, a rotary lock comprises a supporting component, a rotating component and a lock core 10; the lock core 10 is provided with a first matching portion 11, and the first matching portion 11 is provided with a first groove 12; the supporting component comprises a first supporting seat 20, and the first supporting seat 20 comprises a supporting shaft 21, and the supporting shaft 21 is provided with an insertion cavity 22 and a first through groove 23; the insertion cavity 22 is used for the lock core 10 to be inserted; the first through groove 23 is connected with the insertion cavity 22; the first matching portion 11 is used to pass through the first through groove 23; the rotating component comprises a first member 30, and the first member 30 is sleeved on the supporting shaft 21; the first member 30 comprises a first ring body 31; the first groove 12 is used for the first ring body 31 to be embedded so as to limit the first matching portion 11 in the axial direction of the support shaft 21 through the first ring body 31; the first ring body 31 is provided with a first avoidance groove 32, and the first avoidance groove 32 is used for the first matching portion 11 to be inserted.
[0027] When in use, the first component 30 can be rotated around the support shaft 21 so that the first avoidance groove 32 rotates with the first component 30 to the corresponding first through groove 23, and then the lock core 10 is inserted into the insertion cavity 22. At this time, the first matching portion 11 passes through the first through groove 23 and is inserted into the first avoidance groove 32. When the lock core 10 is pushed to the point where the first groove 12 of the first matching portion 11 is facing the first avoidance groove 32, the first component 30 is rotated so that the first ring body 31 is embedded in the first groove 12. At this time, the first ring body 31 can form a blocking effect on the two groove side walls of the first groove 12, so that the first matching portion 11 can be blocked by the first ring body 31. A limit is formed in the axial direction of the support shaft 21, so that the lock core 10 can be locked by utilizing the first component 30 to prevent the lock core 10 from falling off, so as to reduce the locking failure phenomenon after long-term use. In the process of releasing the lock of the lock core 10 by the first component 30, it is only necessary to rotate the first component 30 to make the first avoidance groove 32 be located at a position corresponding to the first groove 12. At this time, the limiting effect of the first ring body 31 on the first matching portion 11 can be removed. By pulling the lock core 10 outward, the first matching portion 11 moves with the lock core 10 and is inserted into the first avoidance groove 32. In this way, the lock core 10 can be moved out, and the lock of the lock core 10 by the first component 30 can be released.
[0028] The first member 30 is provided with a first embedding portion 33, and the support shaft 21 is provided with a first guide groove 24 extending along the circumferential direction thereof and for the first embedding portion 33 to be movably embedded. During the rotation of the first member 30 relative to the support shaft 21, the first embedding portion 33 moves along the first guide groove 24, so that the first embedding portion 33 cooperates with the first guide groove 24 to guide the rotation of the first member 30, so that the rotation of the first member 30 is more flexible and smooth, and the phenomenon of rotation deviation of the first member 30 is avoided.
[0029] Specifically, the first embedding portion 33 is disposed on the first ring body 31 .
[0030] The lock core 10 is provided with a second matching portion 13; a second through groove 25 is also provided on the support shaft 21; the second through groove 25 is connected with the insertion cavity 22, and the second through groove 25 is used for the second matching portion 13 to pass through; the second matching portion 13 is provided with a connecting groove 15 which is connected with the first guide groove 24 and for the first embedding portion 33 to pass through.
[0031] A second groove 14 is provided on the first matching portion 11; the rotating part includes a second component 40, and the second component 40 is mounted on the support shaft 21; the second component 40 includes a second ring body 41; the second groove 14 is used for the second ring body 41 to be embedded so as to limit the first matching portion 11 in the axial direction of the support shaft 21 through the second ring body 41; a second avoidance groove 42 is provided on the second ring body 41, and the second avoidance groove 42 is used for the first matching portion 11 to pass through. When in use, the first component 30 can be rotated around the support shaft 21, so that the first avoidance groove 32 rotates to the corresponding first through groove 23 with the first component 30, and the second component 40 can be rotated around the support shaft 21, so that the second avoidance groove 42 rotates to the corresponding first through groove 23 with the second component 40, and then the lock core 10 is inserted into the insertion cavity 22. At this time, the first matching portion 11 passes through the first through groove 23 and is penetrated in the first avoidance groove 32 and the second avoidance groove 42. As the support shaft 21 is advanced to the point where the first groove 12 of the first matching portion 11 is opposite to the first avoidance groove 32 and the second groove 14 is opposite to the second avoidance groove 42, the first component 30 is rotated so that the first ring body 31 is embedded in the first groove 12, and the second component 40 is rotated so that the second ring body 41 is embedded in the second groove 14. At this time, the first ring body 31 can form a blocking effect on the two groove side walls of the first groove 12, and the second ring body 41 can form a blocking effect on the second groove The two groove side walls of the groove 14 form a blocking effect, so as to limit the first matching portion 11 in the axial direction of the support shaft 21 through the first ring body 31 and the second ring body 41, so that the lock core 10 can be locked by using the first component 30 and the second component 40 to prevent the lock core 10 from falling off, so as to improve the stability of the lock buckle. In the unlocking process, it is only necessary to rotate the first component 30 to make the first avoidance groove 32 located at the position corresponding to the first groove 12, and the second component 40 to rotate to make the second avoidance groove 42 located at the position corresponding to the second groove 14. At this time, the limiting effect of the first ring body 31 and the second ring body 41 on the first matching portion 11 can be removed. By pulling the lock core 10 outward, the first matching portion 11 moves with the lock core 10 and is inserted into the first avoidance groove 32 and the second avoidance groove 42. In this way, the lock core 10 can be removed to complete the unlocking. Moreover, while ensuring the locking stability of the lock buckle, the unlocking and locking operations are relatively simple and convenient to use.
[0032] The second member 40 is provided with a second embedding portion 43, and the support shaft 21 is provided with a second guide groove 26 extending along the circumferential direction thereof and for the second embedding portion 43 to be movably embedded. During the rotation of the second member 40 relative to the support shaft 21, the second embedding portion 43 moves along the second guide groove 26, so that the second embedding portion 43 cooperates with the second guide groove 26 to guide the rotation of the second member 40, so that the rotation of the second member 40 is more flexible and smooth, and the phenomenon of rotation deviation of the second member 40 is avoided.
[0033] The second embedding portion 43 is disposed on the second ring body 41 .
[0034] Specifically, the first guide groove 24 has a first closed end 51 and a first communicating end 52 communicating with the first through groove 23, and the first closed end 51 is used for the first embedding portion 33 to be inserted when the first avoidance groove 32 is located at a position corresponding to the first groove 12; the second guide groove 26 has a second closed end 53 and a second communicating end 54 communicating with the first through groove 23, and the second closed end 53 is used for the second embedding portion 43 to be inserted when the second avoidance groove 42 is located at a position corresponding to the second groove 14; the first communicating end 52 and the second communicating end 54 are respectively disposed at the first through groove 23 and the second through groove 14. On both sides of the through groove 23, the first closed end 51 and the second closed end 53 are respectively arranged on both sides of the first through groove 23. During the rotation of the first component 30 and the second component 40, the first component 30 and the second component 40 rotate in the opposite direction, and the first avoidance groove 32 rotates to the position corresponding to the first groove 12, and the second avoidance groove 42 is located at the position corresponding to the second groove 14. The first embedded portion 33 and the second embedded portion 43 are respectively inserted into the first closed end 51 and the second closed end 53, which can form a positioning effect on the first component 30 and the second component 40, making it convenient to pull out the lock core 10 to open the lock buckle.
[0035] The shapes of the first embedding portion 33 and the second embedding portion 43 can be set according to actual needs, as long as they can be movably embedded in the first guide groove 24 and the second guide groove 26. As a preferred embodiment of the present invention, the first embedding portion 33 and the second embedding portion 43 are both set in a semicircular head shape.
[0036] Preferably, the first groove 12 and the second groove 14 are sequentially arranged on the first matching portion 11 along the axial direction of the support shaft 21. The first matching portion 11 includes a first convex peak, a second convex peak, and a third convex peak sequentially arranged along the axial direction of the support shaft 21, the first groove 12 is formed between the first convex peak and the second convex peak, and the second groove 14 is formed between the second convex peak and the third convex peak. In actual design, the first convex peak and the second convex peak can also be matched to form a first clamping structure for clamping the first ring body 31; the second convex peak and the third convex peak can be matched to form a second clamping structure for clamping the second ring body 41.
[0037] The texture and pattern formed on the outer surface of the first component 30 and the second component 40 can be set according to actual needs (for example, Figure 1 , 6 , 7 settings) to improve the appearance.
[0038] In the actual design process, a mark can also be set on the support component, the first member 30 is provided with a first mark that is opposite to the mark when the first avoidance groove 32 is located at a position corresponding to the first groove 12, and the second member 40 is provided with a second mark that is opposite to the mark when the second avoidance groove 42 is located at a position corresponding to the second groove 14. When in use, by rotating the first member 30 and the second member 40 in opposite directions, and when the first mark and the second mark are aligned with the marks respectively, the first avoidance groove 32 is located at a position corresponding to the first groove 12, and the second avoidance groove 42 is located at a position corresponding to the second groove 14, the lock core 10 can be directly pulled out to open the lock buckle, so as to further facilitate unlocking. In the locking process, the first member 30 only needs to be rotated to the first avoidance groove 32 and the first groove 12 are staggered so that the first ring body 31 is embedded in the first groove 12, and the second member 40 is rotated to the second avoidance groove 42 and the second groove 14 are staggered so that the second ring body 41 is embedded in the second groove 14, so as to achieve the locking of the lock core 10.
[0039] The mark can be set according to actual needs, and the first mark and the second mark can also be set according to actual needs, for example, they can be set as text, numbers or structural features in the form of protrusions (such as Figure 1 or as shown in 6).
[0040] The support component also includes a second support seat 60, on which a clamping column 61 is provided, and a clamping slot 27 is provided on the support shaft 21, and the clamping column 61 is used to fit with the clamping slot 27. During the assembly process, the clamping column 61 of the second support seat 60 is clamped and fitted in the clamping slot 27, so that the second support seat 60 and the first support seat 20 can be fixed as a whole. Preferably, the end of the support shaft 21 is formed as a clamping end 28 for clamping and fitting with the inside of the second support shaft 21, so that the clamping end 28 can fully clamp the inside oblique position of the second support seat 60 to further improve the firmness of the second support seat 60 and the first support seat 20. As a preferred embodiment of the utility model, the clamping slot 27 is provided on both sides of the support shaft 21, and the clamping column 61 for clamping and fitting with the clamping slot 27 can be provided on both sides of the second support seat 60 to further improve the firmness of the second support seat 60 and the first support seat 20.
[0041] Of course, in addition to this, the first support base 20 and the second support base 60 can also be fixed together by means of bayonet pins, bolts, etc. However, fixing the second support base 60 and the first support base 20 together by the above method is the most preferred embodiment of the utility model, which can facilitate the fixation between the two and ensure the stability of the fixation of the two.
[0042] In this embodiment, the first support seat 20 further adopts a first end portion, and the first end portion is provided with a support shaft 21 on an end away from the second support seat 60.
