DETAILED DESCRIPTION

[0031] The preferred embodiments of the utility model will be described in detail below with reference to the drawings, and those skilled in the art will appreciate that these descriptions are only descriptive, exemplary, and should not be interpreted as limiting the protection scope of the utility model.

[0032] It should be noted that: similar signs represent similar items in the following drawings, so once an item is defined in one drawing, it can no longer be further defined and explained in the subsequent drawings.

[0033] This embodiment mainly describes the anti-drop lock buckle that can effectively improve the applicability, and specifically as follows:

[0034] Embodiment one (such as the tent of application lock buckle)

[0035] As shown in Figures 1-9 The anti-drop lock buckle includes rotatably connected main body one 1 and main body two 2, the main body one 1 is fixed with mounting seat one 3, the main body two 2 is fixed with mounting seat two 4, the mounting seat one 3 is rotatably installed with rotator 5, and the rotator 5 is rotatably connected with hook piece 6, the mounting seat two 4 is installed with limiting rod 7, the hook piece 6 is provided with hook part 61 that can hook limiting rod 7, the hook part 61 is bent hook setting and towards the direction where mounting seat one 3 is located, the hook piece 6 is rotatably installed with anti-drop piece 8, the anti-drop piece 8 can limit limiting rod 7 from disengaging hook part 61, that is, limit the rotation of main body one 1 and main body two 2.

[0036] The rotation axis of rotator 5 on mounting seat one 3 is shaft center one a, the rotation axis of hook piece 6 on rotator 5 is shaft center two b, and the rotation axis of anti-drop piece 8 on hook piece 6 is shaft center three c, wherein shaft center one a and shaft center two b are parallelly arranged, shaft center three c deviates from shaft center two b, and shaft center three c is perpendicular to shaft center two b.

[0037] In the embodiment, the hook part 61 of the hook member 6 is provided with two hook parts, and the anti-dropping part 81 of the anti-dropping member 8 is arranged to rotate above the two hook parts 61. The anti-dropping part 81 is arranged at a position where the hook part faces, and a limiting cavity d is formed between the anti-dropping part 81 and the hook member 6. The limiting cavity d can limit the movement of the limiting rod 7. The anti-dropping part 81 is provided with a limiting section one 81a and a limiting section two 81b. The limiting section one 81a and the limiting section two 81b form an included angle therebetween. The limiting section one 81a is arranged obliquely above the hook part 61, and the limiting section two 81b can rotate above or between the two hook parts 61. When the limiting section two 81b rotates above the two hook parts 61, the anti-dropping member 8 and the hook member 6 form an opening part e through which the limiting rod 7 can pass.

[0038] Preferably, the anti-dropping member 8 and the hook member 6 can be connected through damping cooperation, so that the anti-dropping member 8 can only be rotated through external force.

[0039] Or a torsional spring can be installed between the anti-dropping member 8 and the hook member 6. The torsional spring elastically acts on the anti-dropping member 8, so as to ensure that the limiting section two 81b of the anti-dropping part 81 is located between the two hook parts 61. That is, the torsional spring has a maintaining effect on the formation of the limiting cavity d.

[0040] Locked state of the lock: as shown in Figures 5-6 , the shaft center two b is located between the shaft center one a and the mounting seat one 3. The hook part 61 of the hook member 6 hooks the limiting rod 7, and the limiting rod 7 is located in the limiting cavity d. The anti-dropping part 81 of the anti-dropping member 8 limits the limiting rod 7 from leaving the limiting cavity d.

[0041] Preferably, in the locked state of the lock, the mounting seat one 3 can also be located between the shaft center one a and the shaft center two b.

[0042] Unlocked state of the lock: as shown in Figures 7-9 , the limiting rod 7 is located outside the limiting cavity d. That is, the mounting seat one 3, the rotating body 5, the hook member 6 and the anti-dropping member 8 are separated from the limiting rod 7. The main body one 1 and the main body two 2 can be rotated.

[0043] When the lock is operated from the locked state to the unlocked state, the operation steps are as follows.

[0044] Step one: rotate the anti-dropping member 8, so that the limiting section two 81b of the anti-dropping part 81 of the anti-dropping member 8 is rotated above the hook member 6 of the limiting rod 7. An opening part e is formed between the anti-dropping member 8 and the hook member 6.

[0045] Step two: move the hook member 6 through the anti-dropping member 8, so that the hook part 61 of the hook member 6 is separated from the limiting rod 7. That is, the limiting rod 7 is separated from the opening part e formed between the anti-dropping member 8 and the hook member 6, and the limiting cavity d is completed. The unlocking operation is completed.

[0046] When the lock is operated from the unlocked state to the locked state, the operation steps are as follows.

[0047] Step one: rotate the anti-off piece 8, so that the limiting segment two 81b of the anti-off part 81 of the anti-off piece 8 is rotated above the hook piece 6 of the limiting rod 7, and the anti-off piece 8 and the hook piece 6 form a mouth part e;

[0048] Step two: drive the hook piece 6 to move by the anti-off piece 8, so that the hook part 61 of the hook piece 6 hooks the limiting rod 7, that is, the limiting rod 7 enters the limiting cavity d from the mouth part e formed between the anti-off piece 8 and the hook piece 6;

[0049] Step three: rotate the reset anti-off piece 8, and the limiting segment two 81b of the anti-off piece 8 is located between the two hook parts 61, which limits the limiting rod 7 from being separated from the limiting cavity d, and the locking operation is completed. Preferably, the anti-off piece 8 can be reset by manual rotation or spring elastic action.

[0050] In the present application, the anti-off piece 8 is rotatably installed on the hook piece 6, so that the hook piece 6 and the anti-off piece 8 can form a limiting cavity d for limiting the movement of the limiting rod 7. When the lock is unlocked in the locked state, the anti-off piece 8 needs to be rotated in advance, and the hook piece 6 is driven to move by the anti-off piece 8, so that the unlocking of the lock can be realized. Therefore, only the anti-off piece 8 needs to be acted on during the unlocking operation, which ensures that the unlocking operation of the lock is simple, and the two unlocking steps make it difficult for the lock to be opened by mistake due to vibration or accidental touch, effectively ensuring the stability of the locked state of the lock and improving the applicability of the lock.

[0051] As shown in Figure 2 , the anti-off piece 8 is provided with an operation part 82 for rotation operation. In the present embodiment, the operation part 82 is exposed on the hook piece 6, and the hook piece 6 is located between the anti-off part 81 and the operation part 82.

[0052] Preferably, without considering the appearance of the lock, the operation part 82 is exposed on the anti-off piece 8, the hook part 61 of the hook piece 6 can be reversely arranged relative to the position of the mounting seat one 3 or the mounting seat two 4, and the anti-off part 81 is located between the hook part 61 and the operation part 82.

[0053] In other embodiments, the operation part 82 on the anti-off piece 8 can be protrudingly arranged away from the shaft center three c, and a pressing piece is slidingly installed on the hook piece 6, one end of the pressing piece is exposed on the hook piece 6, and the other end is abutted on the operation part 82 of the anti-off piece 8. The pressing piece is pressed to slide, and the operation part 82 of the anti-off piece 8 is pushed by the pressing piece, so that the anti-off piece 8 rotates, and the mouth part e for the limiting rod 7 to enter and exit the limiting cavity d is opened.
