[0020] The connecting portion comprises:

[0021] A body and a limiting cavity arranged in the body, wherein the limiting cavity is provided with the stopper, which is suitable for limiting the circumferential rotation of the stopper.

[0031] A device with a connection structure comprises the above connection structure.

[0032] The device with the connection structure is an electric fan.

[0033] The technical solution of the present invention has the following advantages:

[0034] 1. The connection structure provided by the present invention has the problem that the first connection member and the second connection member are not firmly fixed due to the threaded connection. A stopper is provided between the first connection member and the second connection member, and a biasing member is connected between the stopper and the second connection member. Under the action of the biasing force, the stopper contacts the first connection member, so that when the first connection member rotates in a first direction, the stopper moves in a direction close to the second connection member, and when the first connection member rotates in a second direction, the stopper is in a stopped state, so that the first connection member and the second connection member can only be connected when they rotate in the first direction. When the first and second connecting members are connected together, and when the first and second connecting members are rotated in the second direction, the stopping of the stopping member will prevent the first connecting member and the second connecting member from rotating, so that the two are firmly fixed together; by providing a disassembly and assembly member fixedly connected to the stopping member, when the disassembly and assembly member is driven manually or by other external forces, the external force overcomes the biasing force, and the disassembly and assembly member drives the stopping member to move to be disengaged from the first connecting member, thereby contacting the stopping state of the first connecting member and the stopping member, thereby releasing the fixed connection between the first connecting member and the second connecting member, and then rotating the first connecting member along the second direction can separate it from the second connecting member, thereby realizing convenient disassembly and assembly of the two.

[0035] 2. The connection structure provided by the present invention makes the matching connection between the stop member and the first connecting member more convenient by arranging the first stop portion and the second stop portion at the ends of the stop member and the first connecting member, and by arranging the first meshing structure, the two can cooperate to guide the movement, and by arranging the second meshing structure, the two can cooperate to stop, thereby realizing the firm fixation of the first connecting member and the second connecting member.

[0036] 3. The connection structure provided by the present invention, wherein the first meshing structure is an inclined surface structure, and the second meshing structure is a straight surface structure. By setting the first meshing structure as an inclined surface structure, when the first connecting member rotates along the first direction, the inclined surface can better guide the stopper to compress the biasing member and continue to move; the second meshing structure is set as a straight surface structure, so that when the first connecting member rotates along the second direction, the straight surface structure cannot guide the stopper to compress the biasing member, and can block the rotation of the stopper and the first connecting member, achieving a stopping effect, so that the first connecting member and the second connecting member are more firmly fixed.

[0037] 4. The connection structure provided by the present invention, by configuring the first stop portion and the second stop portion as a right-angle triangular tooth structure, makes the structure of the stop portion and the first connecting member coordinated and connected simpler and the implementation method more convenient.

[0038] 5. The connection structure provided by the present invention makes the processing of the second connection member more convenient by fixing the auxiliary connection member in the outer shell of the second connection member, and is threadedly connected to the first connection member through the first threaded portion, the connection portion is connected to the biasing member, and a stop member is arranged in the connection portion, so that the overall assembly of the connection structure is more convenient and the overall structure is more compact.

[0039] 6. The connection structure provided by the present invention comprises a connecting portion of the auxiliary connecting member including a main body and a limiting cavity provided in the main body, wherein the limiting cavity limits the circumferential rotation of the stop member, thereby ensuring that the stop member can compress the biasing member to move in the limiting cavity, thereby achieving a better stopping effect.

[0040] 7. The connection structure provided by the present invention, by setting a boss connected to the biasing member in the limiting cavity, the shell of the stop member moves in the limiting cavity between the main body and the boss, and the boss moves relatively in the shell of the stop member, so that the fit between the components is more compact and the overall volume of the connection structure is smaller.

[0041] 8. The connection structure provided by the present invention, by setting a convex portion on the shell of the stop member and a moving space for matching connection on the body of the connecting part, enables the stop member and the connecting part to achieve relative movement but not relative rotation, thereby ensuring the relative movement of the first connecting member and the second connecting member and better realizing the stopping function.

[0042] 9. The connection structure provided by the present invention is such that the end of the second threaded portion of the first connecting member away from the main body is in a state of abutting against the end of the first threaded portion provided with the connecting portion, so that the first connecting member and the second connecting member can be tightly connected better when they rotate relative to each other.

[0043] 10. The connection structure provided by the present invention makes the assembly of the disassembly and assembly parts more convenient by correspondingly arranging the first clearance hole and the second clearance hole on the second connection part and the stopper.

[0044] 11. The connection structure provided by the present invention, by setting the first and second clearance holes as long holes set along the axial direction, and the lengths of the first and second clearance holes in the axial direction of the second connecting member are greater than the length of the disassembly member in the axial direction of the second connecting member, so that the disassembly member can move in the first and second clearance holes when subjected to external force, thereby achieving the separation of the stop member from the first connecting member, and facilitating the disassembly of the first and second connecting members.

[0045] 12. The connection structure provided by the present invention can better prevent the rotation of the stop member and ensure the normal movement of the compression biasing member of the stop member by making the extension width of at least one of the first clearance hole and the second clearance hole in the circumferential direction of the second connecting member smaller than the extension width of the disassembly member in the circumferential direction of the second connecting member.

DETAILED DESCRIPTION

[0055] The technical solution of the present invention will be described clearly and completely below in conjunction with the accompanying drawings. Obviously, the described embodiments are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the present invention.

[0056] In addition, the technical features involved in the different embodiments of the present invention described below can be combined with each other as long as they do not conflict with each other.

[0057] like Figure 1 - Figure 6 As shown, a connection structure is provided in this embodiment, including: a first connection member 1, a second connection member 2, a stop member 3, a biasing member and a disassembly member 5.

[0058] The first connecting member 1 is threadedly connected to the second connecting member 2; the stop member 3 is arranged between the first connecting member 1 and the second connecting member 2, and the stop member 3 moves toward the direction close to the second connecting member 2 when the first connecting member 1 rotates along the first direction; one end of the biasing member abuts against the second connecting member 2, and the other end abuts against the stop member 3. Under the biasing force of the biasing member, the stop member 3 contacts the first connecting member 1 and has a stopped state when the first connecting member 1 rotates along the second direction, and the first direction is different from the second direction; the disassembly member 5 is fixedly connected to the stop member 3, and is suitable for driving the stop member 3 to move and disengage from the first connecting member 1 under the action of external force.

[0059] Since the threaded connection between the first connecting member 1 and the second connecting member 2 may have the problem of loose fixation, a stopper 3 is provided between the first connecting member 1 and the second connecting member 2, and a biasing member is connected between the stopper 3 and the second connecting member 2. Under the action of the biasing force, the stopper 3 contacts the first connecting member 1, so that when the first connecting member 1 rotates in the first direction, the stopper 3 moves toward the direction close to the second connecting member 2, and when the first connecting member 1 rotates in the second direction, the stopper 3 is in a stopped state, so that the first connecting member 1 and the second connecting member 2 can only be connected together when they rotate in the first direction. When rotating in the second direction, the stopping of the stop member 3 will prevent the first connecting member 1 and the second connecting member 2 from rotating, so that the two are firmly fixed together; by providing a disassembly and assembly member 5 fixedly connected to the stop member 3, when a person manually or other external force drives the disassembly and assembly member 5, the external force overcomes the biasing force, and the disassembly and assembly member 5 drives the stop member 3 to move to disengage from the first connecting member 1, thereby contacting the stopping state of the first connecting member 1 and the stop member 3, thereby releasing the fixed connection between the first connecting member 1 and the second connecting member 2, and then rotating the first connecting member 1 along the second direction can separate it from the second connecting member 2, thereby realizing convenient disassembly and assembly of the two.

[0060] As a convertible embodiment, the stop member 3 may also move toward the direction approaching the first connecting member 1 when the second connecting member 2 is driven to rotate along the first direction; one end of the biasing member abuts against the first connecting member 1, and the other end abuts against the stop member 3, and under the biasing force of the biasing member, the stop member 3 contacts the second connecting member 2 and has a stopped state when the second connecting member 2 rotates along the second direction; the disassembly member 5 is fixedly connected to the stop member 3, and is suitable for driving the stop member 3 to move and disengage from the second connecting member 2 under the action of external force.

[0061] The stopper 3 and the disassembly member 5 in this embodiment are separate structures, fixedly connected as one body. As a convertible implementation, the stopper 3 and the disassembly member 5 can also be an integrally formed structure.

[0062] The end of the stopper 3 in this embodiment includes a first stopper 9, and the end of the first connecting member 1 includes a second stopper 19 that is connected to the first stopper 9; the first stopper 9 and the second stopper 19 include a first meshing structure, and the first meshing structure guides the stopper 3 to move toward the direction close to the second connecting member 2 when the first connecting member 1 rotates in the first direction; the first stopper 9 and the second stopper 19 include a second meshing structure, and the second meshing structure restricts the rotation of the first connecting member 1 and the second connecting member 2 when the first connecting member 1 rotates in the second direction. By arranging the first stopper 9 and the second stopper 19 at the ends of the stopper 3 and the first connecting member 1, the matching connection of the stopper 3 and the first connecting member 1 is more convenient, and by arranging the first meshing structure, the two can cooperate to guide the movement, and by arranging the second meshing structure, the two can cooperate to stop, so as to achieve the first connecting member 1 and the second connecting member 2. As a convertible embodiment, it is also possible that the first stopper 9 and the second stopper 19 are arranged on the peripheral wall of the stopper 3 and the first connecting member 1.

[0063] In this embodiment, the first meshing structure is an inclined surface structure 6, and the second meshing structure is a straight surface structure 7. By setting the first meshing structure as the inclined surface structure 6, when the first connecting member 1 rotates in the first direction, the inclined surface can better guide the stop member 3 to compress the biasing member and continue to move; the second meshing structure is set as the straight surface structure 7, so that when the first connecting member 1 rotates in the second direction, the straight surface structure 7 cannot guide the stop member 3 to compress the biasing member, and can block the rotation of the stop member 3 and the first connecting member 1, thereby achieving a stopping effect, and making the first connecting member 1 and the second connecting member 2 more firmly fixed. Specifically, the first meshing structure is an inclined plane structure. As a convertible embodiment, the first meshing structure can also be an inclined arc surface structure. As a convertible embodiment, the second meshing structure can also be other non-straight surface structures, as long as it can block the first connecting member 1 from rotating in the second direction.

[0064] Specifically, the first stopper 9 and the second stopper 19 in this embodiment are right-angled triangular tooth structures. By setting the first stopper 9 and the second stopper 19 as right-angled triangular tooth structures, the structure of the stopper and the first connector 1 is simpler and the implementation method is more convenient.

[0065] There are many specific forms of the biasing member, and the biasing member in this embodiment is a spring 4. As a convertible implementation, the biasing member can also be other structures with elasticity.

[0066] In this embodiment, the first connecting member 1 has an external thread; the second connecting member 2 includes an outer shell and an auxiliary connecting member 10 disposed in the outer shell, the auxiliary connecting member 10 includes a first threaded portion 11 and a connecting portion 12, the inner surface of the first threaded portion 11 has an internal thread that cooperates with the external thread; the connecting portion 12 is formed by the end of the first threaded portion 11 facing away from the first connecting member 1 and protruding in a direction away from the first connecting member 1, and the connecting portion 12 is abutted against one end of the biasing member. By fixing the auxiliary connecting member 10 in the outer shell of the second connecting member 2, the processing of the second connecting member 2 is more convenient, and the first threaded portion 11 is threadedly connected to the first connecting member 1, the connecting portion 12 is connected to the biasing member, and a stopper 3 is disposed in the connecting portion 12, so that the overall assembly of the connection structure is more convenient and the overall structure is more compact.

[0067] like Figure 5 As shown, the connection part 12 in this embodiment includes a body and a limiting cavity 13 provided in the body, and a stopper 3 is provided in the limiting cavity 13, which is suitable for limiting the circumferential rotation of the stopper 3. By making the connection part 12 of the auxiliary connecting member 10 include a body and a limiting cavity 13 provided in the body, the limiting cavity 13 limits the circumferential rotation of the stopper 3, ensuring that the stopper 3 can compress the biasing member to move in the limiting cavity 13, thereby achieving a better stopping effect.

[0068] Specifically, in the present embodiment, a boss 14 is provided in the limiting cavity 13, and a biasing member is connected to the boss 14; the stopper 3 includes a shell with a hollow structure, and the shell is provided in the limiting cavity 13 between the main body and the boss 14. By providing the boss 14 connected to the biasing member in the limiting cavity 13, the shell of the stopper 3 moves in the limiting cavity 13 between the main body and the boss 14, and the boss 14 moves relatively in the shell of the stopper 3, so that the fit between the components is more compact and the overall volume of the connection structure is smaller. As a convertible embodiment, it is also possible that the boss 14 is not provided in the limiting cavity 13, the spring 4 is directly connected to the bottom of the main body, and a support column is inserted into the spring 4 to be fixedly connected to the stopper 3 to limit the rotation of the stopper 3.

[0069] like Figure 6As shown, the housing of the stopper 3 in this embodiment is provided with a convex portion 15, and the body of the connecting portion 12 is provided with a moving space 16 that cooperates with the convex portion 15. Specifically, the moving space 16 is a long hole. By providing the convex portion 15 on the housing of the stopper 3 and providing the moving space 16 that cooperates with the connecting portion 12, the stopper 3 and the connecting portion 12 can achieve relative movement but cannot rotate relative to each other, thereby ensuring the relative movement of the first connecting member 1 and the second connecting member 2, and better achieving the stopping function. As a convertible implementation, it is also possible that the moving space 16 is provided on the housing of the stopper 3, and the convex portion 15 that cooperates with the moving space 16 is provided on the body of the connecting portion 12. As a convertible implementation, it is also possible that the moving space 16 is a long groove.

[0070] like Figure 3 As shown, the first connector 1 in this embodiment includes: a main body 17 and a second threaded portion 8 fixedly connected thereto, the second threaded portion 8 is provided with an external thread, the end of the second threaded portion 8 away from the main body 17 is provided with a convex block, the convex block is provided with a second stopper 19, and the end of the second threaded portion 8 away from the main body 17 is in a state of abutting against the end of the first threaded portion 11 provided with the connecting portion 12. The end of the second threaded portion 8 of the first connector 1 away from the main body 17 is in a state of abutting against the end of the first threaded portion 11 provided with the connecting portion 12, so that the first connector 1 and the second connector 2 can be well connected tightly when they rotate relative to each other.

[0071] In order to facilitate the assembly of the disassembly component 5, a first clearance hole 18 is provided on the outer shell of the second connecting component 2 and the auxiliary connecting component 10 in this embodiment, and a second clearance hole is provided on the stopper 3. The first clearance hole 18 and the second clearance hole are arranged correspondingly, and the disassembly component 5 is passed through the first clearance hole 18 and the second clearance hole.

[0072] Specifically, the first clearance hole 18 and the second clearance hole in this embodiment are long holes arranged along the axial direction, and the length of the first clearance hole 18 and the second clearance hole in the axial direction of the second connecting member 2 is greater than the length of the disassembly member 5 in the axial direction of the second connecting member 2. By setting the first clearance hole 18 and the second clearance hole as long holes arranged along the axial direction, and the length of the first clearance hole 18 and the second clearance hole in the axial direction of the second connecting member 2 is greater than the length of the disassembly member 5 in the axial direction of the second connecting member 2, the disassembly member 5 can move in the first clearance hole 18 and the second clearance hole when subjected to external force, thereby achieving the separation of the stopper 3 from the first connecting member 1, and facilitating the disassembly of the first connecting member 1 and the second connecting member 2.

[0073] In this embodiment, the extension width of the first clearance hole 18 and the second clearance hole in the circumferential direction of the second connecting member 2 is smaller than the extension width of the disassembly member 5 in the circumferential direction of the second connecting member 2. By setting it in this way, the rotation of the stopper 3 can be prevented well, and the normal movement of the compression biasing member of the stopper 3 can be ensured. As a convertible embodiment, it is also possible that the extension width of one of the first clearance hole 18 and the second clearance hole in the circumferential direction of the second connecting member 2 is smaller than the extension width of the disassembly member 5 in the circumferential direction of the second connecting member 2.

[0074] This embodiment also provides a device with a connection structure, including the above-mentioned connection structure.

[0075] Specifically, the device with the connection structure in this embodiment is an electric fan. As a convertible implementation, the device with the connection structure can also be other devices that require two connecting members to be connected together.

[0076] The body of the electric fan includes a first connecting member 1 (upper body) and a second connecting member 2 (lower body). When the two need to be assembled together, the first connecting member 1 is rotated clockwise to connect the external thread of the first connecting member 1 with the internal thread of the auxiliary connecting member 10 in the second connecting member 2. The first connecting member 1 is continued to be rotated clockwise. Due to the elastic force of the spring 4, the triangular tooth structure at its end contacts the inclined surface of the triangular tooth structure of the stopper 3. The first connecting member 1 is continued to be rotated clockwise. The first connecting member 1 applies a downward force to the stopper 3. The stopper 3 compresses the spring 4 and moves downward, so that the first connecting member 1 can continue to rotate clockwise to the auxiliary connecting member 10 until the second threaded portion 8 is far away. The end of the main body 17 has an end that abuts against the end of the first threaded portion 11 with the connecting portion 12, so that the first connecting member 1 and the second connecting member 2 are tightly connected; after the first connecting member 1 and the second connecting member 2 are tightly connected, the stop member 3 is acted upon by the spring 4, and the triangular tooth structure of the stop member 3 is stuck into the triangular tooth structure of the first connecting member 1. When the first connecting member 1 is rotated counterclockwise, the straight surface of the triangular tooth structure of the stop member 3 contacts the straight surface of the triangular tooth structure of the first connecting member 1. The stop member 3 is tightly meshed with the first connecting member 1 under the elastic force of the spring 4, so that the first connecting member 1 cannot rotate counterclockwise, thereby achieving the effect of firmly fixing the first connecting member 1 and the second connecting member 2.

[0077] When the two need to be disassembled, manually press the disassembly part 5 downwards. Since the disassembly part 5 and the stop part 3 are fixedly connected as one, the disassembly part 5 will drive the stop part 3 to move downward to overcome the elastic force of the spring 4, so that the triangular tooth structure of the stop part 3 is disengaged from the triangular tooth structure of the first connecting part 1, and the stopping effect of the stop part 3 disappears. The first connecting part 1 can be disassembled from the second connecting part 2 by rotating it counterclockwise.

[0078] Obviously, the above embodiments are merely examples for the purpose of clear explanation, and are not intended to limit the implementation methods. For those skilled in the art, other different forms of changes or modifications can be made based on the above description. It is not necessary and impossible to list all the implementation methods here. The obvious changes or modifications derived therefrom are still within the scope of protection of the invention.
