[0084] Furthermore, the technical features involved in the different embodiments of this utility model described below can be combined with each other as long as they do not conflict with each other.

[0085] The following is combined Figures 1-16 The following describes embodiments of the present invention.

[0086] According to an embodiment of this utility model, a rotating mechanism is provided, including a first connecting structure 1, a second connecting structure 2, a locking member 4, and at least two pressing structures 5; the first connecting structure 1 and the second connecting structure 2 are rotatably connected; a mating structure 3 is provided between the first connecting structure 1 and the second connecting structure 2; the locking member 4 has a locking position that can cooperate with the mating structure 3 and an unlocking position that disengages from the mating structure 3; when the locking member 4 is in the locking position, it can restrict the rotation of the first connecting structure 1 relative to the second connecting structure 2; when the locking member 4 is in the unlocking position, the first connecting structure 1 can rotate relative to the second connecting structure 2; the locking member 4 is disposed on at least one pressing structure 5; any pressing structure 5 subjected to force can switch the locking member 4 between the locking position and the unlocking position. By applying force to any pressing structure 5, the locking member 4 can switch between the locking position and the unlocking position; during use, the user does not need to specifically select a particular pressing structure 5, and can press any pressing structure 5 according to habit to switch the state of the locking member 4, which can effectively improve the ease of use of the product.

[0087] In this application, the locking element 4 and the mating structure 3 can be a buckle and a latch that can be engaged with each other; in this case, the locking position is when the buckle and the latch can be engaged, and the unlocking position is when the two can be disengaged; or, the locking element 4 and the mating structure 3 can be a pin and a socket that can be inserted into each other; in this case, the locking position is when the pin is inserted into the socket, and the unlocking position is when the pin extends out of the socket.

[0088] This application discloses several embodiments in which any pressing structure 5, when subjected to force, can drive the locking member 4 to deform, thereby switching the locking member 4 between a locked position and an unlocked position. Switching the state of the locking member 4 by deformation is a simple, convenient, and low-cost method. The locking member 4 can be made of an elastic material, such as rubber or shape memory metal.

[0089] In some embodiments, the locking member 4 is deformed, such as by extending or retracting, to unlock or lock with the mating structure 3, thereby switching the state of the locking member 4. For example, the locking member 4 is a hook, and the mating structure 3 is a latch, hook, or pin; the deformation of the hook allows it to engage or disengage with the latch, hook, or pin, thereby switching the state of the locking member 4.

[0090] In some embodiments, the locking member 4 is deformed, such as bent or flexed, to unlock or lock with the mating structure 3, thereby switching the state of the locking member 4. The locking member 4 can be a spring arm 514, etc., and the mating structure 3 can include a bayonet, a slot, etc. The spring arm 514 is straightened or bent to engage or disengage with the mating structure 3, thereby switching the state of the locking member 4.

[0091] This application discloses several embodiments in which any pressing structure 5, when subjected to force, can drive the locking member 4 to move relative to the mating structure 3, thereby switching the locking member 4 between a locked position and an unlocked position. The movement of the locking member 4 switches its state, making the operation simple, convenient, and inexpensive.

[0092] In some embodiments, the switching between the unlocked position and the locked position of the locking member 4 is a switching of the position of the locking member 4 relative to the mating structure 3, that is, the relative movement of the locking member 4 and the mating structure 3.

[0093] In some embodiments, the number of locking elements 4 can be set to one or more; when one of the locking elements 4 is in the locked position, the rotation of the first connecting structure 1 and the second connecting structure 2 can be restricted; when all the locking elements 4 are in the unlocked position, the first connecting structure 1 and the second connecting structure 2 can be unlocked.

[0094] In some embodiments, any pressing structure 5 is subjected to force, including the pressing force exerted on the pressing structure 5 when pressed by a user; and a restoring force from the return structure 6 to reset the pressing structure 5. The pressing structure 5 is driven by the pressing force and the restoring force to switch all locking members 4 between an unlocked position and a locked position.

[0095] This application discloses several embodiments in which the mating structure 3 is movably disposed between the first connecting structure 1 and the second connecting structure 2; any pressing structure 5, when subjected to force, can drive the mating structure 3 and / or the locking member 4 to move, thereby switching the locking member 4 between an unlocked position and a locked position. By driving the mating structure 3 and / or the locking member 4 to move through any pressing structure 5, relative movement between the two is achieved, thereby switching the state of the locking member 4, making the operation simpler.

[0096] In this application, at least one of the pressing structure 5 and the locking member 4 is moved by the pressing structure 5, so that the two are relatively movable, thereby switching the position of the locking member 4. The operation is simple and convenient.

[0097] In some embodiments, any one or more pressing structures 5 can drive the locking member 4 to move, and the cooperating structure 3 is fixed between the first connecting structure 1 and the second connecting structure 2; then the locking member 4 can move between the unlocked position and the locked position. In this embodiment, the locking member 4 is fixed on the pressing structure 5, and the movement of any pressing structure 5 drives the locking member 4 to move, so that it moves relative to the cooperating structure 3. Alternatively, the locking member 4 can be movably disposed on the pressing structure 5, and the movement of the pressing structure 5 drives the locking member 4 to move, so that it moves relative to the cooperating structure 3.

[0098] In some embodiments, any one or more pressing structures 5 can drive the mating structure 3 to move, while the locking member 4 is fixedly installed; when the mating structure 3 moves, that is, relative movement occurs between the locking member 4 and the mating structure 3, the locking member 4 can switch between an unlocked position and a locked position. In this embodiment, the movement of any pressing structure 5 can drive the mating structure 3 to move, so that the locking member 4 moves relative to the mating structure 3 to produce relative displacement.

[0099] In some embodiments, any one or more pressing structures 5 drive the locking member 4 to move, and simultaneously, or with a certain time difference, drive the cooperating structure 3 to move; the speeds of their movements are different, yet relative movement can still occur between them. In this case, the locking member 4 can switch between the unlocked position and the locked position. In this embodiment, pressing any one or more pressing structures 5 drives the locking member 4 to move, and simultaneously, also drives the cooperating structure 3 to move, and the speeds of their movements are different, thus generating relative movement between them.

[0100] Alternatively, pressing any one or more of the structures 5 will activate the locking element 4, and continuing to press will activate the cooperating structure 3, at which point the two will move relative to each other.

[0101] In some embodiments, any one of the pressing structures 5 being forced can drive the locking member 4 to switch between the unlocked and locked positions. That is, any pressing structure 5 being pressed or driven by the return structure 6 can drive the locking member 4 to switch between the unlocked and locked positions.

[0102] In some embodiments, pressing any two or more pressing structures 5 simultaneously can also drive the locking member 4 to switch between the unlocked position and the locked position.

[0103] This application discloses several embodiments. Direction one is defined as the extension direction of the rotation axes of the first connecting structure 1 and the second connecting structure 2; direction two is defined as the direction perpendicular to the rotation axes of the first connecting structure 1 and the second connecting structure 2. When any pressing structure 5 is subjected to force, it can drive the locking member 4 to move relative to the mating structure 3 in direction one or direction two, thereby switching the locking member 4 between a locked position and an unlocked position. This allows the locking member 4 to switch precisely and stably between the locked and unlocked positions. When any pressing structure 5 is subjected to force, it can drive the locking member 4 to move along the rotation axis direction of the first connecting structure 1 and the second connecting structure 2, thereby allowing the locking member 4 to engage or disengage with the mating structure 3. This method is simple in structure, convenient to use, and inexpensive.

[0104] In some embodiments, when any one of the pressing structures 5 is subjected to force, it can drive the locking member 4 to move in a second direction, such as radial direction. This can also make the locking member 4 cooperate with or disengage from the mating structure 3. This structure can further reduce the volume of the entire structure, improve the compactness of the product, and further improve the versatility of the product.

[0105] This application discloses several embodiments in which, when any one of the pressing structures 5 is subjected to force, it enables the synchronous movement of all pressing structures 5, thereby switching the locking member 4 between a locked position and an unlocked position. This allows the locking member 4 to respond precisely and ensures that the force on each pressing structure 5 is uniform, preventing damage and thus improving the product's service life. In this embodiment, there is no collision or friction between the pressing structures 5, reducing damage between them and further improving the product's service life.

[0106] In some embodiments, each pressing structure 5 is arranged sequentially in the first direction, and the pressing direction is also the first direction; when any pressing structure 5 is subjected to force, all pressing structures 5 move in the first direction, with a small range of movement, which further reduces the usable space of the product, allowing the product to be used in a small space and improving the usability of the product.

[0107] This application discloses several embodiments in which any number of pressing structures 5 can be simultaneously subjected to force, causing the corresponding pressing structures 5 to move relative to each other, thereby switching the locking member 4 between a locked position and an unlocked position. Through the relative movement between the pressing structures 5, the locking member 4 deforms or the relative cooperating structure 3 moves, allowing the locking member 4 to switch between two states; this method is easy to manufacture and inexpensive. Users can press any number of pressing structures 5 simultaneously according to their habits, driving the locking member 4 to move between the locked and unlocked positions, making operation simpler, conforming to the usage habits of various users, and improving the user experience.

[0108] This application discloses several embodiments. The pressing structure 5 includes a first pressing structure 51 and a second pressing structure 52 disposed opposite to each other. A locking member 4 is disposed on the first pressing structure 51 and / or the second pressing structure 52. The pressing directions of the first pressing structure 51 and the second pressing structure 52 are different. That is, the locking member 4 can be disposed only on the first pressing structure 51, or it can be disposed on both the first pressing structure 51 and the second pressing structure 52. This makes the structure more compact and conforms to user habits, improving the user experience.

[0109] This application discloses several embodiments. A first pressing structure 51 includes a first button 513 and a spring arm 514 connected to each other; a locking member 4 is disposed on the spring arm 514. A second pressing structure 52 includes a second button 523 and a pushing structure 524 connected to each other; the spring arm 514 and the pushing structure 524 are positioned correspondingly. When either or both of the first button 513 and the second button 523 are subjected to force, the pushing structure 524 can apply or release force to the spring arm 514, allowing the spring arm 514 to switch between a deformed state and a free state, thereby driving the locking member 4 to switch between a locked position and an unlocked position. The pushing structure 524 drives the spring arm 514 to deform, enabling the locking member 4 to move. This design is convenient to operate and allows the locking member 4 to switch states accurately and stably; moreover, the structure is simple and inexpensive.

[0111] This application discloses several embodiments in which each spring arm 514 is arranged sequentially around the outer periphery of the pushing structure 524. The outer peripheral wall of the pushing structure 524 is provided with pushing members 5241 corresponding to each spring arm 514. When any one or both of the first button 513 and the second button 523 are subjected to force, the pushing structure 524 can drive each pushing member 5241 to simultaneously apply or de-force to each spring arm 514, allowing each spring arm 514 to switch simultaneously between a deformed state and a free state, thereby allowing each locking member 4 to switch simultaneously between a locked position and an unlocked position.

The setting of the relief groove 5141 not only ensures that the pushing structure 524 can effectively apply force or unload force to the spring arm 514, but also improves the deformation of the spring arm 514.
