[0029] The present invention is described in detail below in conjunction with the various embodiments shown in the accompanying drawings, but it should be noted that these embodiments are not limitations of the present invention, and any equivalent transformations or substitutions in functions, methods, or structures made by ordinary technicians in the field based on these embodiments are all within the scope of protection of the present invention.

[0030] See attached Figure 1-4 As shown, in this embodiment, the locking mechanism is first disclosed, and then the use of the locking mechanism is disclosed, which is specifically introduced as follows.

[0031] The locking mechanism in this embodiment includes a locking mechanism 1 including a locking pin 11 and a locking portion 2, wherein the locking portion 2 is provided with a locking groove 21 matching the locking mechanism 1. When the locking mechanism 1 is inserted into the locking portion 2, the driving mechanism 3 drives the locking mechanism 1 to move along the locking portion 2 to a set position, and the locking pin 11 falls into the locking groove 21 to achieve locking.

[0032] In the prior art, locking usually requires multiple operations, such as locking by pressing, etc., while in the present embodiment, rotation is required, so that the locking pin happens to be located near the locking groove, and then automatically falls into the locking groove to complete the locking, and the use process is simple.

[0033] In this embodiment, the positional relationship such as misalignment is cleverly utilized, so that the locking mechanism moves upward during rotation, and then stops rotating when it reaches the highest point, and falls directly into the locking groove by gravity to complete the locking.

[0034] In order to facilitate the operation of rotation, in this embodiment, a guide portion 22 is provided in the locking portion 2 at a position offset from the side of the locking groove 21, for guiding the locking spring pin 11 to approach or move away from the locking groove 21. In this embodiment, the guide portion 22 can be used to guide the locking spring pin 11 to rotate along the expected path, so as to guide it from being offset from the locking groove to being close to the locking groove, thereby providing a basis for automatic falling later.

[0035] In this embodiment, the locking is actually completed inside, and the locking part 2 forms an assembly shell, and the guide part 22 forms an upward rotation guide groove along the inner wall of the assembly shell, so that the locking mechanism 1 rotates to approach or move away from the locking groove 21. By forming an upward rotation guide groove, the locking mechanism 1 rotates upward and is located above the locking groove 21. When it reaches the highest point of the rotation guide groove, it continues to rotate and moves downward. At this time, it stops rotating. Under the action of gravity, part of the locking pin 11 located at the highest point automatically falls and enters the locking groove 21, achieving the effect of automatic falling and only rotating to lock.

[0036] In this embodiment, in order to ensure stability, the locking groove 21 forms a reduced diameter cavity toward the center of the assembly cavity, and the guide portion 22 protruding from the inner wall of the assembly cavity forms a guide path toward the center of the assembly cavity. It can be seen from the accompanying drawings that the guide portion 22 protrudes from the inner wall of the assembly cavity toward the center, and then extends toward the inner wall of the assembly cavity at the innermost point (i.e., the highest point of the previous rotation guide groove) to form a guide path connected to the locking groove, thereby causing the locking pin to tilt downward under the action of gravity and fall into the locking groove.

[0037] In this embodiment, in order to further achieve assembly stability, one of the locking mechanism 1 and the locking portion 2 is provided with an insertion portion 12, and the other is a sliding groove 23 that matches the insertion portion and forms a sliding track. In this embodiment, when the locking mechanism rotates, the insertion portion can be rotated into the sliding groove 23, thereby achieving locking and clamping of the locking mechanism and the locking portion at two locations, and achieving better stability.

[0038] In this embodiment, in order to avoid mutual interference during assembly, the insertion portion 12 is protruding from the locking mechanism 1 or the locking portion 2, and an avoidance groove 13 is formed between the locking mechanism 1 or the locking portion 2. In this embodiment, due to the addition of the avoidance groove 13, the insertion portion enters without causing interference. Specifically, in this embodiment, the locking mechanism 1 is partially concave to form the avoidance groove 13, and the bottom of the avoidance groove 13 constitutes the insertion portion 12. During assembly, the insertion portion and the locking pin in the assembly cavity are rotated to enter the corresponding sliding groove and locking groove, respectively.

[0039] In this embodiment, the entire rotation is mainly performed in the horizontal direction, so the insertion portion 12 is protruded in the horizontal direction, and the sliding groove 23 forms an arc groove. The arc groove has low friction during rotation and is easy to operate.

[0040] When the locking mechanism in this embodiment is used for a stand, such as an animal stand, the specific structure is that it includes an upper cover assembly 4 including a locking mechanism 1, and a base 5 including a locking portion 2, and there are at least two locking mechanisms 1 along the circumference of the upper cover assembly 4. That is, in this embodiment, there are at least two locking positions, and then one rotation can achieve locking or unlocking of multiple locking mechanisms, which improves the use efficiency, and multiple locking mechanisms form multiple lockings, which ensures that when the upper cover 4 and the base 5 are assembled and locked, multiple positions are locked, and the stability is good.

[0041] In order to facilitate the locking and unlocking of the bracket, especially to facilitate user operation, in this embodiment, the driving mechanism 3 is a button assembly 6 protruding from the upper cover assembly 4, and the two locking mechanisms 1 are linked to the button assembly 6. In this embodiment, the button assembly protrudes from the upper cover 4, and during rotation, multiple locking pins 11 are locked with the locking grooves 21, and then the button assembly is operated to drive the locking pin 11 to move toward the center of the assembly cavity, away from the locking groove 21, and then rotate to achieve unlocking.

[0042] In this embodiment, for the convenience of operation, the upper cover assembly 4 is a trumpet-shaped structure with an opening toward the base 5. The trumpet-shaped structure has the largest opening toward the base 5. When locked, the locking spring pin 11 is arranged at the largest opening, which provides a better space for the position relationship and space of the structure; at the same time, in this embodiment, the base 5 is an expanded cavity, so that when the bracket is locked or unlocked by force, the base has space and force to expand outward, which has a better effect.

[0043] As shown in the accompanying drawings, the base 5 in this embodiment includes a first base 51 with the locking portion 2, and a second base 52 supported on the inner wall of the first base 51. In this embodiment, the entire lock is in the first base 51, and the second base 52 supports it, which has the function of enhancing force and support during the locking process.

[0044] As shown in the accompanying drawings, in order to realize the assembly and locking of the locking mechanism 1, the upper part of the assembly shell formed by the first base 51 forms a plurality of the locking parts 2, and the middle and lower parts of the first base 51 form an expanded diameter support. In this embodiment, the first base 51 is expanded, and thus during the locking, the locking pin that automatically falls has a downward force, and thus support needs to be considered. At this time, the structure of the first base 51 has a good supporting effect.

[0045] For the purpose of beautiful assembly, an assembly portion is formed on the outer periphery of the locking portion 2, and the second base 52 is fitted to the inner wall of the first base 51 and assembled at the assembly portion. In this embodiment, if the second base 52 is only fitted, it may fall off during the process of locking and rotating. In this case, the locking portion 2 is used to form a plurality of assembly portions, thereby realizing the assembly of a plurality of second bases 52. In this embodiment, the second base is an arc-shaped structure with good fit.

[0046] In this embodiment, it is mainly used for pet stands, and its multiple locking mechanisms 1 form a multi-claw locking mechanism, making it easier to operate and more reliable in terms of locking stability. At the same time, in this embodiment, the locking pin 11 does not need to press the unlocking button during the locking process, but the guide portion 22 formed by the inclined structure guides the locking pin 11 to automatically fall into the locking groove 21 of the base 5 during the rotation of the upper cover assembly 4. However, when unlocking is required, the unlocking button (i.e., the button assembly 6) must be pressed first before the upper cover can be rotated. This operation requires two consecutive actions, which is more reasonable to prevent accidental touches of the unlocking structure.

[0047] The use environment of this embodiment is as follows: insert the upper cover assembly 4 with the insertion part 21 with protruding multiple claws and forming a plurality of locking spring pins 11 into the locking groove 21 formed by the groove on the corresponding base 5, and rotate it by a certain angle after insertion. During the rotation process, the locking spring pin 11 assembled in the upper cover assembly 4 will follow the guide part 22 formed by the guide slope of the base groove and automatically fall into the locking groove 21 of the base 5, and the base 5 and the upper cover assembly 4 will be locked; if you want to unlock, you need to first fully press the unlocking button (i.e., the button assembly 6) of the upper cover assembly 4 to ensure that the locking spring pin 11 is completely out of the locking groove 21 of the base 5, and then rotate it in the opposite direction by a certain angle to pull the upper cover assembly 4 out of the base 5, so that the upper cover assembly 4 and the base 5 can be separated;

[0048] When assembling the structure in this embodiment, the assembly process is as follows:

[0049] 1. First, the button and the button slider (the button slider contains a copper nut) are fastened together by a tight fit to form a button assembly 6, on which a reset compression spring 7 is sleeved, and then the button assembly 6 and the reset compression spring 7 are assembled into the assembly cavity formed by the upper cover assembly 4. At this time, the locking pin 11 is screwed to the copper nut of the button slider (that is, the locking pin 11 forms a linkage relationship with the button assembly 6). At this time, the button assembly 6 can be freely reset after being pressed.

[0050] The usage in this embodiment is as follows:

[0051] 1. The upper cover assembly 4 contains a plurality of raised claws (i.e., the insertion portion 12). The claws on the upper cover assembly 4 are aligned and inserted into the grooves (i.e., the sliding grooves 23) of the base 5. After insertion, the upper cover assembly 4 is rotated at a certain angle. During the rotation process, the locking pin 11 assembled in the upper cover assembly 4 will follow the guide slope (i.e., the guide portion 22) of the base 5 and automatically fall into the locking groove 21 of the base 5. The base 5, the button, and the locking mechanism 1 will be locked;

[0052] 2. When unlocking, first fully press the unlocking button (i.e., button assembly 6) of the upper cover to drive the locking pin to move toward the center of the upper cover assembly 4, thereby ensuring that the locking pin 11 is completely out of the locking groove 21 of the base 5, and then rotate it in the opposite direction for a certain angle, pull the upper cover assembly 4 out of the base 5, and the upper cover assembly 4 can be separated from the base 5.

[0053] The structure in this embodiment cleverly utilizes the dislocated assembly relationship, and then rotates in coordination to align the dislocated structure, and at the same time, the locking pin 11 moves outward, so that even if it is not locked at this time, it cannot be directly taken out from the base. At this time, it enters the locking groove and locks with gravity; then when unlocking, the key assembly is used to form a drive, so that the locking pin moves inward and away from the locking groove 21, and then the locking pins on the entire upper cover assembly 4 are centrally stored to achieve removal and separation from the smaller opening of the base 5. In this embodiment, the first base 51 can be made of hard plastic or other materials to form a hard support structure, and the second base 52 can be made of soft rubber or other materials to form a better fitting effect, so that both have their own better effects.

[0054] In this embodiment, a plurality of hollow structures are formed on the upper cover assembly 4, so that the upper cover assembly 4 forms a relatively light structure. The base 5 forms an assembly cavity. In this embodiment, an assembly disk is provided in the base 5 to form the locking portion 2, and then an annular groove is extended upward along the assembly disk, and then the locking portion 2 is provided in the annular groove, providing conditions for the assembly of the locking mechanism 1 on the upper cover assembly 4.
