Description

Technical Field

[0001] The utility model relates to the technical field of splicing structures, and more specifically, to a splicing structure and a fan assembly having the same. Background Art

[0002] Currently, for electric fans or household appliances with splicing functions in the prior art, the splicing connection of two splicing components is mainly achieved through a threaded structure.

[0062] It should be noted that, without conflict, the embodiments in this application and the features in the embodiments can be combined with each other. The present utility model will be described in detail below with reference to the drawings and in combination with the embodiments.

[0063] As shown Figures 1 to 14 in the figure, Embodiment 1 of the present utility model provides a splicing structure, which includes a first splicing member 10, a second splicing member 20 and a limiting member 30. At least part of the first splicing member 10 is sleeved on at least part of the second splicing member 20. A first clamping portion 41 is provided on the inner wall of at least part of the first splicing member 10, and a second clamping portion 42 adapted to the first clamping portion 41 is provided on the outer wall of at least part of the second splicing member 20. The first clamping portion 41 and the second clamping portion 42 are arranged along the sleeving direction of at least part of the first splicing member 10. The limiting member 30 is sleeved on at least part of the first splicing member 10, and the limiting member 30 is rotatably arranged on the first splicing member 10 to rotate to a limiting position and an avoidance position; when the limiting member 30 is in the limiting position, the inner wall of the limiting member 30 fits against the outer wall of the first splicing member 10 corresponding to the part where the first clamping portion 41 is provided; when the limiting member 30 is in the avoidance position, the inner wall of the limiting member 30 is spaced from the outer wall of the first splicing member 10 corresponding to the part where the first clamping portion 41 is provided, so that the first clamping portion 41 has a deformation space, so that the first clamping portion 41 and the second clamping portion 42 can be clamped or separated.

[0064] When using the splicing structure provided by the embodiment of the present utility model, when it is necessary to splice the first splicing member 10 and the second splicing member 20, first make the limiting member 30 in the avoidance position, so that the first clamping portion 41 has a deformation space, so that the first clamping portion 41 and the second clamping portion 42 are clamped, so that at least part of the first splicing member 10 is sleeved on the second splicing member 20; then make the limiting member 30 in the limiting position, so that the inner wall of the limiting member 30 fits against the outer wall of the first splicing member 10 corresponding to the part where the first clamping portion 41 is provided, to limit the deformation of the outer wall of the first splicing member 10 corresponding to the part where the first clamping portion 41 is provided, thereby avoiding the loosening of the first clamping portion 41 and the second clamping portion 42 and ensuring the clamping reliability of the first clamping portion 41 and the second clamping portion 42. When it is necessary to separate the already spliced first splicing member 10 and second splicing member 20, rotate the limiting member 30 to the avoidance position, so that the limiting member 30 is spaced from the outer wall of the first splicing member 10 corresponding to the part where the first clamping portion 41 is provided, so that the first clamping portion 41 has a deformation space, so that the first clamping portion 41 can deform, so as to facilitate the separation of the first clamping portion 41 and the second clamping portion 42 after deformation. Therefore, by using the splicing structure provided in this embodiment, only by rotating the limiting member 30 to the avoidance position or the limiting position can the locking or release of the splicing part of the first splicing member 10 and the second splicing member 20 be realized, and the splicing operation is convenient and simple. Therefore, through the splicing structure provided by the embodiment of the present utility model, the technical problem of inconvenient splicing of the splicing structure in the prior art can be solved.

[0065] Specifically, the splicing structure in this embodiment does not require multiple turns of rotation to lock the first splicing member 10 and the second splicing member 20, nor does it require at least one of the first splicing member 10 and the second splicing member 20 to rotate integrally for multiple turns. Therefore, there will be no problem of the power cord being wound due to rotation, and there will be no situation where the relative positions at the splicing part are different due to different rotational torques for tightening the first splicing member 10 and the second splicing member 20. Thus, there will be no problem that at least one of the first splicing member 10 and the second splicing member 20 has an axial misalignment or inclination between the first splicing member 10 and the second splicing member 20 due to multiple turns of rotation, nor will there be a situation where the first splicing member 10 and the second splicing member 20 shake due to insecure splicing. Therefore, the splicing stability of the first splicing member 10 and the second splicing member 20 in this application can be guaranteed, and thus the axial connection stability of the first splicing member 10 and the second splicing member 20 can also be ensured.

[0066] Specifically, the first engaging portion 41 is a first hook (or buckle), the second engaging portion 42 is a second hook (or buckle), and at least one of the first hook and the second hook can undergo a certain amount of elastic deformation so that the first hook and the second hook move from a separated state to an engaged state or from an engaged state to a separated state. The first hook and the second hook can achieve pre-tightening and fixing of the first splicing member 10 and the second splicing member 20 in the axial direction. Specifically, the first hook and the second hook can be made of plastic material. Alternatively, the first engaging portion 41 is a hook, the second engaging portion 42 is a slot, the hook can undergo a certain amount of elastic deformation so that the hook and the slot move from a separated state to an engaged state or from an engaged state to a separated state, and the hook and the slot can achieve pre-tightening and fixing of the first splicing member 10 and the second splicing member 20 in the circumferential direction, and the hook can be made of plastic material.

[0067] In order to better achieve the engaging stability of the first engaging portion 41 and the second engaging portion 42, an interference can be provided between the first engaging structure and the second engaging portion 42 in the locking direction, so that the first splicing member 10 and the second splicing member 20 are tightly connected in the axial direction without shaking.

[0068] Specifically, the rotation angle corresponding to the position-limiting position and the avoidance position of the position-limiting member 30 in this embodiment is less than 90°. Preferably, the rotation angle corresponding to the position-limiting position and the avoidance position of the position-limiting member 30 can be 60°. In this way, it is only about 1 / 18 of the rotation angle of the threaded splicing structure, greatly reducing the degree of rotation, making it convenient and fast to use and easy to operate.

[0069] In this embodiment, the cross-section of the outer wall of the second splicing member 20 is circular, and the cross-section of the inner wall of the limiting member 30 is elliptical; when the limiting member 30 is in the limiting position, the part of the inner wall of the limiting member 30 corresponding to the minor axis of the limiting member 30 is in contact with the outer wall of the first splicing member 10 corresponding to the part provided with the first clamping portion 41; when the limiting member 30 is in the avoiding position, the part of the inner wall of the limiting member 30 corresponding to the minor axis of the limiting member 30 is arranged in a dislocation manner with the outer wall of the first splicing member 10 corresponding to the part provided with the first clamping portion 41. With the above structural arrangement, it is convenient to realize the switching of the limiting member 30 between the limiting position and the avoiding position, and the operation is more convenient.

[0070] Specifically, the length corresponding to the minor axis of the ellipse of the inner wall of the limiting member 30 is equal to the length of the diameter of the circle corresponding to the outer wall of the first splicing member 10, so that when the limiting member 30 is in the limiting position, it can effectively ensure that the part of the inner wall of the limiting member 30 corresponding to the minor axis of the limiting member 30 is in contact with the outer wall of the first splicing member 10 corresponding to the part provided with the first clamping portion 41.

[0071] Specifically, the first splicing member 10 includes a first splicing main body 11 and a first sleeving portion 12 connected to each other, the first sleeving portion 12 forms at least part of the first splicing member 10, the second splicing member 20 includes a second splicing main body 21 and a second sleeving portion 22 connected to each other, the second sleeving portion 22 forms at least part of the second splicing member 20, and the limiting member 30 is sleeved on the first sleeving portion 12; the outer shape of the limiting member 30 is the same as the outer shape of at least one of the first splicing main body 11 and the second splicing main body 21. With such a structural arrangement, it is convenient to effectively ensure the consistency of the overall outer shape of the splicing structure, reduce the structure with obvious bosses or depressions, so as to facilitate the user to carry or transfer, and also avoid the situation that the bosses or depressions are prone to bumps.

[0072] In order to better ensure the overall appearance consistency of the splicing structure, preferably, the outer shape of the limiting member 30, the outer shape of the first splicing main body 11 and the outer shape of the second splicing main body 21 are all the same, that is, the limiting member 30, the first splicing main body 11 and the second splicing main body 21 can all be circular cross-sections, arc cross-sections or square cross-sections with the same size.

[0073] In this embodiment, a first abutting portion 51 is provided on the outer wall of the first splicing member 10, the first abutting portion 51 and the first clamping portion 41 are arranged at intervals along the circumferential direction of the first splicing member 10, and a second abutting portion 52 for abutting and cooperating with the first abutting portion 51 is provided on the inner wall of the limiting member 30. Among them, when the limiting member 30 is in the limiting position, the first abutting portion 51 abuts against the second abutting portion 52. With such a structural arrangement, the setting stability of the limiting member 30 in the limiting position can be further improved, so as to ensure that the limiting member 30 can stably limit the first splicing member 10.

[0074] Specifically, the first abutting portion 51 is a first abutting strip, and the first abutting strip protrudes from the outer wall of the first splicing member 10. The second abutting portion 52 is a second abutting strip, and the second abutting strip protrudes from the inner wall of the limiting member 30. With such a structural arrangement, the structure is simple and the limiting is stable. In addition, it can avoid the first abutting portion 51 and the second abutting portion 52 occupying too much space and hindering the rotation process of the limiting member 30.

[0075] Specifically, there are at least two first abutting portions 51, and the at least two first abutting portions 51 are oppositely arranged on both sides of the outer wall of the first splicing member 10. There are at least two second abutting portions 52, and the at least two second abutting portions 52 are arranged in one-to-one correspondence with the at least two first abutting portions 51, and each second abutting portion 52 abuts and cooperates with the corresponding first abutting portion 51. With such a structural arrangement, when the limiting member 30 is in the limiting position, the stability of the set position of the limiting member 30 can be further improved.

[0076] Specifically, an avoidance groove adapted to at least part of the outer shape of the first abutting portion 51 is provided on the second abutting portion 52, so that when the first abutting portion 51 abuts against the second abutting portion 52, at least part of the first abutting portion 51 is located in the avoidance groove. With such a structural arrangement, it is convenient to better enable the limiting member 30 to be stably in the limiting position, avoid the situation that the limiting member 30 easily loosens from the limiting position, and further improve the limiting stability of the limiting member 30 to the first splicing member 10.

[0077] In this embodiment, there are at least two first abutting portions 51. One of the at least two first abutting portions 51 is arranged on one side of the outer wall of the first splicing member 10, and the other of the at least two first abutting portions 51 is arranged on the other side of the outer wall of the first splicing member 10; there are at least two second abutting portions 52, and the at least two second abutting portions 52 are arranged in one-to-one correspondence with the at least two first abutting portions 51, and each second abutting portion 52 is used to abut and cooperate with the corresponding first abutting portion 51. Among them, one of the at least two first abutting portions 51 abuts against one side of the corresponding second abutting portion 52, and the other of the at least two first abutting portions 51 abuts against the other side of the corresponding second abutting portion 52. With such a structural arrangement, through such a relatively opposing abutment, the stability of the set position of the limiting member 30 in the limiting position can be further improved, so as to better limit the first splicing member 10 and avoid the first engaging portion 41 provided on the first splicing member 10 from being deformed and loosening.

[0078] Specifically, a third abutting portion 53 for cooperating with the first abutting portion 51 is provided on the inner wall of the limiting member 30, and the third abutting portion 53 and the second abutting portion 52 are spaced apart along the peripheral direction of the inner wall of the limiting member 30. When the limiting member 30 is in the avoidance position, the first abutting portion 51 abuts against the third abutting portion 53. With such a structural arrangement, when the limiting member 30 is in the avoidance position, the arrangement stability of the limiting member 30 can be improved, so as to facilitate the splicing of the first splicing member 10 and the second splicing member 20 or the separation of the first splicing member 10 and the second splicing member 20, and facilitate the operation.

[0079] Specifically, the first abutting portion 51 is a first abutting strip, which is protruded from the outer wall of the first splicing piece 10, and the third abutting portion 53 is a third abutting strip, which is protruded from the inner wall of the limiting member 30. With such a structural arrangement, the structure is simple, and the avoidance position of the limiting member 30 can be stably limited. In addition, it can also avoid that the first abutting portion 51 and the third abutting portion 53 occupy too much space and hinder the rotation process of the limiting member 30, thereby improving the smoothness of the rotation of the limiting member 30.

[0080] In this embodiment, there are at least two first abutting portions 51, and at least two first abutting portions 51 are disposed opposite to each other on two sides of the outer wall of the first splicing piece 10. There are at least two third abutting portions 53, and at least two third abutting portions 53 are disposed one-to-one correspondingly to at least two first abutting portions 51, and each third abutting portion 53 abuts and cooperates with the corresponding first abutting portion 51. With such a structural arrangement, when the limiting member 30 is in the avoidance position, the stability of the setting position of the limiting member 30 can be further improved.

[0081] Specifically, the third abutting portion 53 is provided with a matching groove that matches at least a portion of the outer edge of the first abutting portion 51, so that when the first abutting portion 51 abuts the third abutting portion 53, at least a portion of the first abutting portion 51 is located in the matching groove. In this way, it is convenient to better enable the limiting member 30 to be stably in the avoidance position, avoid the limiting member 30 from easily being displaced or loosened from the avoidance position, and better facilitate the splicing or separation of the first splicing piece 10 and the second splicing piece 20.

[0082] Specifically, there are at least two first abutting portions 51, one of the at least two first abutting portions 51 is arranged on one side of the outer wall of the first splicing piece 10, and the other of the at least two first abutting portions 51 is arranged on the other side of the outer wall of the first splicing piece 10; there are at least two third abutting portions 53, and the at least two third abutting portions 53 are arranged one-to-one with the at least two first abutting portions 51, and each third abutting portion 53 is used to abut and cooperate with the corresponding first abutting portion 51. Among them, one of the at least two first abutting portions 51 abuts against one side of the corresponding third abutting portion 53, and the other of the at least two first abutting portions 51 abuts against the other side of the corresponding third abutting portion 53. With such a structural setting, the setting stability of the limiter 30 in the avoidance position can be further improved through such a relatively opposed abutment, so as to better enable the first splicing piece 10 and the second splicing piece 20 to be spliced ​​or separated, and to facilitate disassembly or assembly.

[0083] Specifically, a first guide portion 61 is further provided on the outer wall of the first splicing piece 10, and a second guide portion 62 for guiding and matching with the first guide portion 61 is provided on the inner wall of the limiting piece 30. Among them, one of the first guide portion 61 and the second guide portion 62 is a guide protrusion, and the other of the first guide portion 61 and the second guide portion 62 is a guide groove, and the guide protrusion is rotatably arranged in the guide groove; when the limiting piece 30 is in the limiting position, the guide protrusion abuts against the groove wall at one end of the guide groove; when the limiting piece 30 is in the avoidance position, the guide protrusion abuts against the groove wall at the other end of the guide groove. With such a structural setting, it is convenient to better guide and limit the rotation of the limiting piece 30, and the limiting piece 30 can be better limited at the avoidance position or the limiting position through the abutment of the guide protrusion with the groove walls at both ends of the guide groove, thereby improving the action stability of the limiting piece 30.

[0084] Specifically, the guide protrusion is an arc-shaped protrusion structure, and the guide groove is a corresponding arc-shaped groove structure.

[0085] Specifically, there are at least two first guides 61, and at least two first guides 61 are arranged at intervals along the peripheral direction of the outer wall of the first splicing piece 10, there are at least two second guides 62, and at least two second guides 62 are arranged at intervals along the peripheral direction of the inner wall of the stopper 30, and at least two second guides 62 are arranged one-to-one with at least two first guides 61, and each second guide 62 is guided and matched with the corresponding first guide 61. With such a structural arrangement, it is convenient to better guide the rotation direction of the stopper 30, so as to better ensure the rotation stability of the stopper 30.

[0086] In this embodiment, a first anti-rotation portion 71 is provided on at least a part of the inner wall of the first splicing member 10. The first anti-rotation portion 71 is spaced apart from the first clamping portion 41. A second anti-rotation portion 72 adapted to the first anti-rotation portion 71 is provided on at least a part of the outer wall of the second splicing member 20. With such a structural arrangement, it is possible to better prevent relative rotation between the first splicing member 10 and the second splicing member 20 after splicing, improve the splicing stability of the first splicing member 10 and the second splicing member 20, and avoid the problem of inaccurate circumferential position of the insertion of the first splicing member 10 and the second splicing member 20.

[0087] Specifically, one of the first anti-rotation portion 71 and the second anti-rotation portion 72 is an anti-rotation groove, and the other of the first anti-rotation portion 71 and the second anti-rotation portion 72 is an anti-rotation protrusion. The anti-rotation protrusion is arranged in the anti-rotation groove. In this way, the structure is simple and the anti-rotation stability is improved.

[0088] Specifically, both the first anti-rotation portion 71 and the second anti-rotation portion 72 are at least two. The at least two first anti-rotation portions 71 are spaced apart along the circumference of at least a part of the inner wall of the first splicing member 10. The at least two second anti-rotation portions 72 are spaced apart along the circumference of at least a part of the outer wall of the second splicing member 20. The at least two first anti-rotation portions 71 and the at least two second anti-rotation portions 72 are arranged in one-to-one correspondence. Each second anti-rotation portion 72 is used for anti-rotation cooperation with the corresponding first anti-rotation portion 71. In this way, it is possible to better prevent the possibility of rotation of the first splicing member 10 and the second splicing member 20, and improve the splicing stability of the first splicing member 10 and the second splicing member 20.

[0089] Specifically, at least one of the first anti-rotation portion 71 and the second anti-rotation portion 72 extends in the axial direction of the first splicing member 10. With such a structural arrangement, it is possible to further improve the anti-rotation effect and better prevent the first splicing member 10 from rotating relative to the second splicing member 20.

[0090] In this embodiment, a third clamping portion 81 is provided on at least a part of the outer wall of the first splicing member 10, and a fourth clamping portion 82 for clamping and cooperating with the third clamping portion 81 is provided on the inner wall of the limiting member 30. The third clamping portion 81 and the fourth clamping portion 82 are arranged along the sleeving direction of the limiting member 30. Among them, the third clamping portion 81 and the first clamping portion 41 are arranged at intervals along the circumferential direction of at least a part of the first splicing member 10. With such a structural arrangement, it is possible to facilitate ensuring the axial sleeving stability of the limiting member 30 sleeved on the first splicing member 10 and prevent the limiting member 30 from randomly disengaging from the first splicing member 10. At the same time, by arranging the third clamping portion 81 and the fourth clamping portion 82 at intervals along the circumferential direction of at least a part of the first splicing member 10, it is possible to prevent the clamping of the third clamping portion 81 and the fourth clamping portion 82 from interfering with the clamping of the first clamping portion 41 and the second clamping portion 42, and it is also possible to prevent the clamping deformation process of the third clamping portion 81 and the fourth clamping portion from interfering with and affecting the clamping deformation process of the first clamping portion 41 and the second clamping portion, which is convenient for the first clamping portion 41 and the second clamping portion 42 to be independently clamped with the third clamping portion 81 and the fourth clamping portion 82 respectively, so as to ensure the clamping between the limiting member 30 and the first splicing member 10 and the clamping between the first splicing member 10 and the second splicing member 20 respectively.

[0091] Specifically, the third clamping portion 81 and the fourth clamping portion 82 can be a hook or a buckle structure.

[0092] Specifically, when the splicing structure in this embodiment is installed, the fixing ring (corresponding to the limiting member 30) is installed on the lower pipe (corresponding to the first splicing member 10) from top to bottom. The axial buckle (corresponding to the fourth clamping portion 82) of the fixing ring is clamped with the limiting buckle (corresponding to the third clamping portion 81) of the lower pipe to achieve axial limitation. At the same time, the first guiding portion 61 of the lower pipe is placed inside the second guiding portion 62 of the fixing ring, so that the fixing ring can only rotate a certain angle (the specific angle can be set to 60°) and will not rotate excessively. In the locked and separated states of the fixing ring, the locking limiting rib (corresponding to the second abutting portion 52) or the separating limiting rib (corresponding to the third abutting portion 53) of the fixing ring is respectively clamped on the positioning bump (corresponding to the first abutting portion 51) of the lower pipe. This positioning only provides a small torque, which is convenient for the user to rotate, and at the same time, the fixing ring will not rotate in the locked state.

[0093] Specifically, the splicing method of the splicing structure in this embodiment is as follows: Rotate the fixing ring counterclockwise to lock the separating limiting rib on the positioning bump of the lower pipe (at this time, the fixing ring and the lower pipe are in a misaligned state, and the first clamping portion 41 of the lower pipe can be deformed). Then insert the upper pipe (corresponding to the second splicing member 20) into the lower pipe, so that the first clamping portion 41 of the lower pipe snaps into the second clamping portion 42 of the upper pipe to complete pre-locking (when inserting, the second anti-rotation portion 72 of the upper pipe is aligned with the first anti-rotation portion 71 of the lower pipe to prevent circumferential misalignment between the upper pipe and the lower pipe). Then rotate the fixing ring clockwise to make the locking limiting rib on the positioning bump of the lower pipe, and the small diameter of the fixing ring is aligned with the outer wall portion corresponding to the first clamping portion 41 of the lower pipe, so that the first clamping portion 41 is limited and cannot be deformed, and the upper pipe is locked (at this time, the fixing ring and the lower pipe are not misaligned, realizing the appearance integrity). At the same time, when the first clamping portion 41 is locked, there is an interference in the locking direction with the second clamping portion 42 of the upper pipe, so that the upper pipe and the lower pipe will not shake when locked.

[0094] The disassembly method of the splicing structure in this embodiment is as follows: Rotate the fixing ring counterclockwise to lock the separating limiting rib on the positioning bump of the lower pipe (at this time, the fixing ring and the lower pipe are in a misaligned state, and the elastic buckle of the lower pipe can be deformed). Then pull out the upper pipe from the lower pipe to complete the separation. The above rotation direction positioning is viewed from top to bottom.

[0095] Embodiment 2 of the present utility model provides a fan assembly, which includes: the splicing structure provided in the above Embodiment 1 and the head assembly 90, and the head assembly 90 is installed on the first splicing member 10 of the splicing structure or the second splicing member 20 of the splicing structure.

By operating the limiting member, it is convenient to limit or avoid the first clamping member, so as to facilitate the splicing or separation of the first splicing member and the second splicing member, simplify the splicing operation of the splicing structure, and improve the splicing stability of the splicing structure.
