[0055] Technologies, methods, and equipment known to ordinary technicians in the relevant art may not be discussed in detail, but where appropriate, the technologies, methods, and equipment should be considered part of the specification.

[0056] The present application embodiment provides a locking structure 10, see Figures 1 to 17 As shown, the locking structure 10 includes: a first structural member 110 and a second structural member 120, the first structural member 110 includes a first regional structure 111 and a second regional structure 112 connected end to end to form a ring, and a rotating portion 113 arranged between the first regional structure 111 and the second regional structure 112; the second structural member 120 includes: a connecting portion 121 and a limiting portion 122, one end of the connecting portion 121 is rotatably connected to the rotating portion 113, and the limiting portion 122 is connected to the side of the other end of the connecting portion 121 and forms a locking space between the first regional structure 111 that can lock the target structure 20; when the connecting portion 121 rotates relative to the first structural member 110, the limiting portion 122 can switch between a first state and a second state, and in the first state, it is opposite to the first regional structure 111 to lock the target structure 20, and in the second state, it is opposite to the second regional structure 112 to release the target structure 20.

[0057] When locking the target structure 20, at least a portion of the target structure 20 is placed on the surface of the first regional structure 111 corresponding to the locking space. As the connecting portion 121 rotates relative to the rotating portion 113, the limiting portion 122 connected to the connecting portion 121 can switch between the first state and the second state. When the limiting portion 122 switches to the first state, the limiting portion 122 is opposite to the first regional structure 111 to lock the target structure 20 in the locking space between the limiting portion 122 and the first regional structure 111, so that the target structure 20 cannot move in the direction of the limiting portion 122 or the first regional structure 111 to escape from the locking space, thereby achieving locking of the target structure 20; when the limiting portion 122 switches to the second state, the limiting portion 122 is opposite to the second regional structure 112 to escape from the restriction on the target structure 20, so that the target structure 20 can move in a direction away from the first regional structure 111 to escape from the locking space, thereby achieving unlocking. It can be seen that when unlocking the target structure 20, there is no need to disassemble the second structural member 120, so as to avoid problems such as increased workload and fire caused by the falling of the structural member.

[0058] Here, the first area structure 111 and the second area structure 112 can both be arc-shaped structures, and form a ring after docking with each other, for example: the first area structure 111 and the second area structure 112 are symmetrical arc-shaped structures, and form a ring after docking with each other; for example: the first area structure 111 and the second area structure 112 are asymmetrical to each other, and form a ring after docking with each other. The rotating portion 113 can be a rotating recessed portion that is concave downward in the plane between the first area structure 111 and the second area structure 112 so that the connecting portion 121 can extend into the rotating recess and be rotatably connected to the inner wall of the rotating recess, or a rotating column that is raised between the first area structure 111 and the second area structure 112 so that the connecting portion 121 can be mounted on the rotating column and be rotatably connected to the outer wall of the rotating column, or a rotating column that is raised between the first area structure 111 and the second area structure 112 so that the connecting portion 121 can be mounted on the rotating column and be rotatably connected to the outer wall of the rotating column, or a rotating column that is raised between the first area structure 111 and the second area structure 112. Figures 3 to 7 and Figure 12 to Figure 14 The rotation recessed on the protruding rotation column between the first region structure 111 and the second region structure 112 is provided so that the connection portion 121 can extend into the rotation recess and be rotationally connected to the inner wall of the rotation recess. The connection portion 121 is rotationally connected to the rotation portion 113. Compared with the setting of screw rotation to disengage, in this rotation mode, the connection portion 121 does not disengage from the rotation portion 113 during the rotation process. The limiting portion 122 is connected to a section of a circle of side surfaces at the other end of the rotation portion 113, so that the limiting portion 122 is opposite to the first region structure 111 in the first state, and is opposite to the second region structure 112 in the second state.

[0059] In some embodiments, see Figures 3 to 7 and Figure 12 to Figure 14As shown, the rotating portion 113 is a rotating concave portion, and the inner side wall of the rotating concave portion is provided with a first step surface 1131 facing away from the opening of the rotating concave portion; one end of the connecting portion 121 is located in the rotating concave portion and can rotate relative to the rotating concave portion, and the connecting portion 121 is provided with a second step surface 1211 abutting against the first step surface 1131. In other words, the first structural member 110 and the connecting portion 121 are both abutted by the first step surface 1131 and the second step surface 1211, and the first step surface 1131 is arranged facing away from the connecting portion 121, so that after the connecting portion 121 is connected to the rotating concave portion, it is restricted by the first step surface 1131 and cannot be separated from the rotating concave portion by itself, so that the probability of the second structural member 120 being separated from the first structural member 110 by itself can be reduced.

[0060] In specific implementation, the connection part 121 and the rotating recess can also be provided with adsorption structures that can adsorb each other, or an interference fit connection between the connection part 121 and the rotating recess, so as to reduce the probability of the second structural member 120 detaching from the first structural member 110 by itself.

[0061] In some embodiments, see Figures 2 to 5 to Figure 7 and Figure 12 to Figure 14 As shown, a circle of inner wall A at the opening of the rotating recess has a tendency to gradually shrink toward the inner bottom wall of the rotating recess; and / or, the peripheral side surface B of the end of the connecting portion 121 away from the limiting portion 122 has a tendency to gradually shrink toward the direction away from the limiting portion 122. In other words, the opening of the rotating recess and the connecting portion 121 are respectively provided with a first guiding slope and a second guiding slope, and in the process of assembling the connecting portion 121 in the rotating recess, the second guiding slope moves along the first guiding slope so that the connecting portion 121 is assembled in the rotating recess, and because the second guiding slope moves along the first guiding slope, the process of assembling the connecting portion 121 in the rotating recess is smoother and more efficient.

[0062] In some embodiments, the inner side wall between the first step surface 1131 and the inner bottom wall of the rotating recess is provided with at least one circle of the first guide structure; one end of the connecting portion 121 is provided with a second guide structure adapted to the first guide structure, so that when one end of the connecting portion 121 rotates in the rotating recess, the second guide structure moves along the first guide structure; wherein, one of the first guide structure and the second guide structure is a guide groove, and the other is a guide protrusion. That is to say, the inner wall of the rotating recess and the two surfaces of the connecting portion 121 facing each other are respectively provided with the first guide structure and the second guide structure, both of which are annular, and one of the first guide structure and the second guide structure is inside the other and can move along the inner wall of the other when the connecting portion 121 rotates relative to the rotating recess, so that the movement process between the connecting portion 121 and the rotating recess is smoother; for example, the first guide structure is a multi-circle guide groove provided on the inner side wall of the rotating recess, and the second guide structure is raised at the position corresponding to the guide groove to form a guide protrusion and is located in the guide groove at the corresponding position.

[0063] In some embodiments, see Figures 2 to 7 As shown, one end of the connection portion 121 includes a plurality of sub-ends 1212, and there is an extrusion space 1213 between the plurality of sub-ends 1212. The plurality of sub-ends 1212 can squeeze the extrusion space 1213 close to each other to enter the rotating recess and return to the state before squeezing in the rotating recess, and the second guide structure is respectively provided at the position of the plurality of sub-ends 1212 corresponding to the first guide structure. In other words, the plurality of sub-ends 1212 are respectively elastic, so that they can elastically shrink into the rotating recess, and can return to the state before shrinking after entering the rotating recess to abut against the inner wall of the rotating recess, so as to be interference-fitted in the rotating recess, so that the probability of the second structural member 120 switching between the first state and the second state by itself can be reduced, and the probability of the second structural member 120 detaching from the first structural member 110 by itself can be reduced, and one end of the connection portion 121 can rotate relative to the rotating recess when subjected to a rotational force.

[0064] It should be noted that the surfaces where the first guide structure and the second guide structure contact each other are relatively smooth, so as to relatively reduce the resistance applied by the rotating recess to the connecting part 121 when the connecting part 121 rotates, thereby reducing the probability of the sub-end 1212 not rotating or even breaking.

[0065] In some embodiments, see Figure 12 to Figure 14 As shown, one end of the connecting portion 121 is annular and can be squeezed in a shrinking manner to enter the rotating recess and return to the state before squeezing in the rotating recess, thereby interference fitting in the rotating recess, and one end of the connecting portion 121 can rotate relative to the rotating recess when subjected to rotational force.

[0066] In some embodiments, the first region structure 111 and the second region structure 112 are symmetrically arranged; in the first state, the orthographic projection of the limiter 122 onto the first structural member 110 covers at least a portion of the first region structure 111; in the second state, the orthographic projection of the limiter 122 onto the first structural member 110 covers at least a portion of the second region structure 112. For example: Figures 1 to 4 and Figures 8 to 10 As shown, the first region structure 111 and the second region structure 112 are symmetrically arranged, and in the first state, the orthographic projection of the limiter 122 to the first structural member 110 covers the entire first region structure 111; in the second state, the orthographic projection of the limiter 122 to the first structural member 110 covers the entire second region structure 112. The symmetrical arrangement reduces the structural complexity of the manufacturing equipment for manufacturing the locking structure 10.

[0067] In some embodiments, see Fig.11 , Fig.12 and Figures 15 to 17 As shown, the second regional structure 112 includes: a third regional structure 1121 and a fourth regional structure 1122, and the third regional structure 1121, the fourth regional structure 1122 and the first regional structure 111 are connected end to end in sequence to form a ring; the first structural member 110 also includes: a stop portion 114, which is connected to the third regional structure 1121, and the surface of the stop portion 114 corresponding to the first regional structure 111 is a first stop surface 1141, and the surface corresponding to the fourth regional structure 1122 is a second stop surface 1142; the limiting portion 122 rotates with the connecting portion 121 relative to the rotating portion 113 to switch between abutting the first stop surface 1141 and the second stop surface 1142. Thus, in the first state, the orthographic projection of the limiting portion 122 onto the first structural member 110 covers at least a portion of the first regional structure 111 and abuts against the first stop surface 1141; in the second state, the orthographic projection of the limiting portion 122 onto the first structural member 110 covers at least a portion of the fourth regional structure 1122 and abuts against the second stop surface 1142. The provision of the stop portion 114 can reduce the probability of the second structural member 120 rotating relative to the first structural member 110 in the first state / second state.

[0068] In some embodiments, see Fig.18 As shown, when the limiting portion 122 abuts against the first stop surface 1141, the limiting portion 122 and the first stop surface 1141 are connected with each other in a concave-convex manner. In this way, the probability of the limiting portion 122 rotating relative to the first structural member 110 when the limiting portion 122 abuts against the first stop surface 1141 can be reduced, or in other words, the limiting portion 122 can be better maintained in a state of abutting against the first stop surface 1141, so as to better maintain the locking structure 10 locking the target structure 20.

[0069] Here, it can be Fig.18 and Fig.19 As shown in the figure, the limiting portion 122 is provided with a limiting protrusion 1221, and the first stop surface 1141 is provided with an adaptive limiting recess corresponding to the position of the limiting protrusion 1221, and the limiting protrusion 1221 cooperates with the limiting recess to achieve a concave-convex connection; it can also be an opposite setting, that is, the limiting protrusion 1221 is provided on the first stop surface 1141, and the limiting recess is provided on the limiting portion 122.

[0070] In some embodiments, see Fig.16 As shown, the first regional structure 111 and the second regional structure 112 are symmetrically arranged; in the first state, the orthographic projection of the limiting portion 122 to the first structural member 110 covers at least a portion of the first regional structure 111 and abuts against the first stop surface 1141; in the second state, the orthographic projection of the limiting portion 122 to the first structural member 110 covers at least a portion of the fourth regional structure 1122 and abuts against the second stop surface 1142. The symmetrical arrangement reduces the structural complexity of the manufacturing equipment for manufacturing the locking structure 10.

[0071] In some embodiments, see Figure 1 , Figure 3 , Figure 4 , Figure 6 , Figure 7 , Figures 9 to 15 and Fig.17 As shown, a non-spherical groove 123 is recessed on the surface of the second structural member 120 away from the first structural member 110. In this way, the operating tool adapted to the groove 123 can be rotated after being inserted into the groove 123 to drive the second structural member 120 where the groove 123 is located to rotate relative to the first structural member 110, so that the switching of the limiting portion 122 between the first state and the second state can be conveniently achieved.

[0072] In some embodiments, see Figure 1 , Figure 3 , Figure 4 , Figure 6 , Figure 7 , Figures 9 to 15 and Fig.17 As shown, the groove 123 is cross-shaped and corresponds to the position of the connecting portion 121. Thus, when the cross-shaped structure of the operating tool is inserted into the cross-shaped groove 123 and rotated, the rotational force provided by the operating tool mainly acts on the connecting portion 121 connected to the rotating portion 113, thereby making the second structural member 120 more efficient in rotation relative to the first structural member 110.

[0073] In specific implementation, the locking structure 10 can be as follows Figure 6 , Figure 7 , Fig. 9 , Fig.10 , Fig.15 and Fig.17 The device shown is fixed on a plate 30, which may or may not be provided with circuits.

[0074] In one example, see Figures 1 to 10 As shown, the locking structure 10 includes:

[0075] The first structural member 110 includes: a first regional structure 111 and a second regional structure 112 connected end to end to form a ring, and a rotating portion 113 arranged between the first regional structure 111 and the second regional structure 112; the first regional structure 111 and the second regional structure 112 are symmetrically arranged; the rotating portion 113 is as follows Figures 3 to 7 The rotating recess is a recessed rotating part on the rotating column protruding between the first area structure 111 and the second area structure 112, and the inner side wall of the rotating recess is provided with a first step surface 1131 facing away from the opening of the rotating recess.

[0076] The second structural member 120 includes: a connecting portion 121 and a limiting portion 122, one end of the connecting portion 121 includes a plurality of sub-end portions 1212, and an extrusion space 1213 is provided between the plurality of sub-end portions 1212, and the plurality of sub-end portions 1212 can be mutually squeezed to squeeze the extrusion space 1213 to enter the rotating recess and restore to the state before squeezing in the rotating recess, and the plurality of sub-end portions 1212 located in the rotating recess can rotate relative to the rotating recess under the action of the rotating force, and the connecting portion 121 is provided with a second step surface 1211 abutting against the first step surface 1131; the limiting portion 122 is connected to the side surface of the other end of the connecting portion 121 and forms a locking space capable of locking the target structure 20 with the first regional structure 111, when the connecting portion 121 rotates relative to the first structural member 110, the limiting portion 122 can switch between the first state and the second state, and in the first state, it is opposite to the first regional structure 111 to lock the target structure 20, and in the second state, it is opposite to the second regional structure 112 to release the target structure 20.
