Many specific details are set forth in the following description to provide a thorough understanding of this application. However, this application can be implemented in many other ways different from those described herein, and those skilled in the art can make similar modifications without departing from the spirit of this application. Therefore, this application is not limited to the specific embodiments disclosed below.

[0089] In the description of this application, it should be understood that if terms such as "center", "longitudinal", "lateral", "length", "width", "thickness", "upper", "lower", "front", "rear", "left", "right", "vertical", "horizontal", "top", "bottom", "inner", "outer", "clockwise", "counterclockwise", "axial", "radial", "circumferential" appear, these terms indicate the orientation or positional relationship based on the orientation or positional relationship shown in the accompanying drawings, and are only for the convenience of describing this application and simplifying the description, and do not indicate or imply that the device or element referred to must have a specific orientation, or be constructed and operated in a specific orientation, and therefore should not be construed as a limitation of this application.

[0090] Furthermore, where the terms "first" and "second" appear, these terms are for descriptive purposes only and should not be construed as indicating or implying relative importance or implicitly specifying the number of technical features indicated. Thus, a feature defined with "first" or "second" may explicitly or implicitly include at least one of that feature. In the description of this application, where the term "multiple" appears, "multiple" means at least two, such as two, three, etc., unless otherwise explicitly specified.

[0091] In this application, unless otherwise expressly specified and limited, the terms "installation," "connection," "joining," and "fixing," etc., shall be interpreted broadly. For example, they may refer to a fixed connection, a detachable connection, or an integral part; a mechanical connection or an electrical connection; a direct connection or an indirect connection through an intermediate medium; or the internal communication of two components or the interaction between two components, unless otherwise expressly limited. Those skilled in the art can understand the specific meaning of the above terms in this application based on the specific circumstances.

[0092] In this application, unless otherwise expressly specified and limited, the use of descriptions such as "above" or "below" the second feature indicates that the first and second features are in direct contact or indirect contact via an intermediate medium. Furthermore, "above," "on top of," and "over" the second feature can mean that the first feature is directly above or diagonally above the second feature, or simply that the first feature is at a higher horizontal level than the second feature. Similarly, "below," "below," and "under" the second feature can mean that the first feature is directly below or diagonally below the second feature, or simply that the first feature is at a lower horizontal level than the second feature.

[0093] It should be noted that if an element is referred to as being "fixed to" or "set on" another element, it can be directly on the other element or there may be an intervening element. If an element is considered to be "connected to" another element, it can be directly connected to the other element or there may be an intervening element. If so, the terms "vertical," "horizontal," "upper," "lower," "left," "right," and similar expressions used in this application are for illustrative purposes only and do not represent the only possible implementation.

[0094] As stated in the background art, the applicant discovered that curtain hooks in related technologies are usually fixedly connected to the wall by anchors (such as expansion bolts, self-tapping screws, etc.), and the hanging brackets (such as the hook body) are set facing the room and cannot be rotated. In this setting, when children play (such as chasing), the end of the hanging bracket can easily scratch clothing and human skin, resulting in poor safety. Based on this, the applicant conducted research and development and experiments on curtain accessories.

[0095] During the research and development process, the applicant adopted a rotatable bracket, which allows the bracket to be close to the wall. This design not only reduces the space occupied by the bracket but also improves safety. However, this design has the problem of limiting the bracket to the target position. Therefore, the applicant improved the fixing device, which improved the stability and ease of operation of the bracket during rotation.

[0096] The present application will now be described in detail with reference to the accompanying drawings.

[0097] According to some embodiments of this application, such as Figures 1 to 2 As shown, the fixing device is used to fix the curtains. The fixing device includes a hanging bracket 1, a first base 2, a first rotating member 3, and at least one first elastic component 4. The hanging bracket 1 is used to hang the curtains. The first base 2 is used to fix the curtains to the mounting structure. The first rotating member 3 connects to the hanging bracket 1 and is rotatably connected to the first base 2. The first rotating member 3 includes a first mating section D1, and a plurality of first recesses 31 are spaced circumferentially along the outer peripheral wall of the first rotating member 3. The first elastic component 4 includes a first elastic member 41 and a first abutment member 42, which are located on one side of the outer peripheral wall of the first mating section D1. The first elastic member 41 engages between the first base 2 and the first rotating member 3, so that the first abutment member 42 abuts against the outer peripheral wall of the first mating section D1.

[0098] In this application, the fixing device is used to fix the curtains, which can be understood as gathering or hooking the curtains to secure them. The hanging bracket 1, as a component of the fixing device, is used to hang or hook the curtains, such as a curtain hook, thus securing the curtains. The first rotating member 3 is rotatably connected to the hanging bracket 1, allowing the hanging bracket 1 to rotate at an angle during use. The first rotating member 3 can be a pivot, a cylinder, or a cylinder with an annular end. Here, the first rotating member 3 can be directly or indirectly connected to the hanging bracket 1. The first elastic component 4 includes a first elastic member 41 and a first abutting member 42. The first elastic member 41 provides an elastic force, and the first abutting member 42, due to the elastic force, abuts or engages with the first recess 31 of the first rotating member 3, allowing the first rotating member 3 to rotate from its initial position (the position before the hanging bracket 1 rotates) to its target position (the position to which the hanging bracket 1 rotates according to usage requirements), thus having a locking effect and improving stability.

[0099] The first seat 2 serves to fix the device to the mounting structure and limit the position of the first elastic component 4. It is understood that the first seat 2 limits the position of the first elastic component 4 to reduce positional displacement when the first elastic component 41 abuts against the first abutting component 42. The fixing method can be through expansion bolts, self-tapping screws, or clips, etc., which will not be elaborated here. The mounting structure can be a wall, decorative elements installed on the wall, or wall columns, etc., which are not limited here. The first mating section D1 can be part of the first rotating component 3, and its function is to allow the first rotating component 3 to clear the space for the first recess 31. The function of the first recess 31 in mating with the first abutting component 42 is to engage with the first abutting component 42, thereby achieving a locking effect and improving the stability of the hanging bracket 1 in the target position. The first elastic component 41 provides elastic force to the first abutting component 42, allowing the first abutting component 42 to elastically abut against the outer peripheral wall of the first mating section D1.

[0100] For details, please refer to Figures 1 to 3 The fixing device is used to secure the curtains. The fixing device includes a hanging bracket 1, a first base 2, a first rotating member 3, and at least one first elastic component 4. The hanging bracket 1 is used to hang the curtains, allowing light to enter the room when the curtains are not in use (e.g., when sun shading is not required). The first base 2 is fixedly connected to the mounting structure, and the fixed connection method can be expansion bolt connection, self-tapping screw connection, or snap-fit ​​connection, etc. The first rotating member 3 connects to the hanging bracket 1 and is rotatably connected to the first base 2. It can be understood that by connecting one end of the first rotating member 3 to the hanging bracket 1 and the other end rotatably connected to the first base 2, the user can rotate the hanging bracket 1 to the target position, thereby improving the ease of operation of the hanging bracket 1.

[0101] Continue to refer to Figures 1 to 3 The first rotating member 3 includes a first mating section D1, which can be a part of the first rotating member 3. Multiple first recesses 31 are spaced circumferentially along the outer peripheral wall of the first rotating member 3. These multiple first recesses 31 can be fitted onto the outer peripheral wall of the first rotating member 3 or integrally formed with it. By circumferentially spaced the multiple first recesses 31 on the outer peripheral wall of the first mating section D1, when the hanging member 1 drives the first rotating member 3 to rotate, the multiple first recesses 31 located in the first mating section D1 can rotate accordingly. This arrangement makes the device compact, reduces the loss of rotational force, and thus improves rotational efficiency.

[0102] The first elastic component 4 includes a first elastic element 41 and a first abutting element 42, which are disposed on one side of the outer peripheral wall of the first mating section D1. The first elastic element 41 is fitted between the first seat 2 and the first rotating member 3, so that the first abutting element 42 abuts against the outer peripheral wall of the first mating section D1. It can be understood that the first elastic element 41 can provide an elastic force. Due to the elastic force, the first abutting element 42 abuts or engages with the first recess 31 of the first rotating member 3, so that the first rotating member 3 has a locking effect when rotated to the target position. This improves the situation where the hanging support 1 connected to the first rotating member 3 returns to its initial position due to loosening, and improves the operational stability of this fixing device.

[0103] It is understandable that by limiting the first elastic component 4 through the seat, the first elastic element 41 provides elastic force, so that the first abutting element 42 can elastically abut against the outer peripheral wall of the first mating section D1. When the hanging support 1 rotates, the first rotating element 3 and the first elastic component 4 can be in a snap-fit ​​state (locking effect), which improves the hanging support 1 connected to the first rotating element 3 from returning to the initial position due to loosening, and improves the stability of the operation of this application.

[0104] For example, the first elastic component 4 can be set to one, two, or other quantities. It is understood that the number of first elastic components 4 can be determined according to the weight of the curtain to be hung on the hanging bracket 1. The more first elastic components 4 and first recesses 31 are set, the greater the load-bearing capacity of the hanging bracket 1 on the curtain.

[0105] Accordingly, in the device of this application, since the first rotating member 3 is connected to the hanging member 1 and can be rotatably connected to the first base 2, when the user only needs to rotate the hanging member 1, the hanging member 1 can rotate along the rotation axis of the first rotating member 3. The first rotating member 3 abuts and cooperates with the first elastic component 4, which improves the problem that the existing hanging member 1 is unable to rotate and is prone to tearing clothes and human skin. This makes the present application have the beneficial effects of convenient operation and high safety.

[0106] For example, the first seat 2 can limit the first elastic component 4 by having a cavity inside the first seat 2 to limit the first elastic component 4, a blind hole to limit the first elastic component 4, or a pipe clamp to limit the first elastic component 4; no limitation is made here.

[0107] For example, the first elastic element 41 may be a cylindrical helical spring, a conical spring, or a rectangular spring.

[0108] For example, the first abutment 42 may be a steel ball, ball bearing, tapered roller, spherical object, or needle roller.

[0109] For example, the shape of the first recess 31 can match that of the first abutment 42. For instance, if the first abutment 42 is a ball bearing, the shape of the first recess 31 can be an arc-shaped recess. Alternatively, if the first abutment 42 is a tapered roller, the shape of the first recess 31 can be a tapered recess. Or, if the first abutment 42 is a needle roller, the shape of the first recess 31 can be a cylindrical recess that matches the needle roller. It is understood that appropriate configurations can be adopted depending on the actual mating conditions.

[0110] In some embodiments, a first spacer 32 is defined between two adjacent first recesses 31 along the circumferential direction of the first rotating member 3. The fixing device has a first state in which the first abutting member 42 abuts against the first spacer 32, and a second state in which the first abutting member 42 abuts against the first recesses 31. The fixing device is capable of switching between the first state and the second state in response to the rotation of the first rotating member 3 relative to the first base 2.

[0111] In this application, the first spacer 32 can be a protruding connecting part between two adjacent first recesses 31. Its function is to form an abutment wall between the first spacer 32 and the first recesses 31, so that the first abutment 42 and the first recesses 31 can be engaged. The first abutment 42 can be located between adjacent abutment walls, which reduces the occurrence of loosening when the first rotating member 3 rotates to the target position and improves the stability of the overall device.

[0112] Please continue to refer to this. Figures 1 to 3The first rotating member 3 is combined with the first spacer 32. A first spacer 32 can be provided between two adjacent first recesses 31 along the circumference of the first rotating member 3. The straight-line distance between the outer surface of the first spacer 32 and the axis of the first rotating member 3 can be greater than the straight-line distance between the inner surface of the recess and the axis of the first rotating member 3. The fixing device has a first state where the first abutting member 42 abuts against the first spacer 32, and a second state where the first abutting member 42 abuts against the first recess 31. The first rotating member 3 can switch between the first and second states during its rotation relative to the first seat 2. With this configuration, by rotating the hanging bracket 1, the user can rotate the first recess 31 in the first rotating member 3 connected to the hanging bracket 1 to engage with the first abutting member 42 at multiple angles, improving the existing situation where the hanging bracket 1 cannot rotate, and enhancing the convenience of operation and the feel of use.

[0113] In some embodiments, the opening area of ​​the first recess 31 has various values. The center line of the opening of the first recess 31 and the rotation axis of the first rotating member 3 are perpendicular to each other.

[0114] In this application, the opening area of ​​the first recess 31 can be of various types. "Various types" here refers to the fact that it can have various shapes, such as an arc-shaped recess, a conical recess, or a cylindrical recess. Correspondingly, the shape of the first abutment 42 can also be of various types. The first recess 31 only needs to match the shape of the first abutment 42, and is not limited here. The center line of the opening of the first recess 31 can be a symmetrical center line along the direction of the opening of the first recess 31 and the rotation axis of the first rotating member 3. The rotation axis of the first rotating member 3 refers to the central rotation axis of the first rotating member 3.

[0115] For details, please refer to Figures 1 to 3 The center line of the opening of the first recess 31 and the rotation axis of the first rotating member 3 are perpendicular to each other. This arrangement allows the installer to directly assemble the first abutment member 42 with the first recess 31 by pressing, thus improving the assembly efficiency of the device.

[0116] For example, the opening of the first recess 31 is defined by the inner wall of the first recess 31 and the outer peripheral wall of the first mating section D1.

[0117] In some embodiments, all first recesses 31 include a plurality of first target portions 31A and a plurality of second target portions 31B, wherein the opening area of ​​the first target portion 31A is larger than the opening area of ​​the second target portion 31B. The plurality of first target portions 31A and the plurality of second target portions 31B are arranged circumferentially along the first rotating member 3.

[0118] In this application, the first target portion 31A or the second target portion 31B can be one of the first recesses 31. Alternatively, the first target portion 31A can be another first recess 31 that is different from the first target portion 31A, for example, by the difference in the opening area of ​​the recess. Both the first target portion 31A and the second target portion 31B can serve as the part that abuts / locks into the first abutting member 42.

[0119] For details, please refer to Figures 1 to 3 The combination of multiple first target parts 31A and multiple second target parts 31B is arranged circumferentially on the outer peripheral wall of the first mating section D1 of the first rotating part 3. The opening area of ​​the first target part 31A can be larger than the opening area of ​​the second target part 31B. In this way, when the user rotates the hanging support 1, the rotation angle can be accurately judged, thereby improving the accuracy and versatility of operation.

[0120] One configuration method is to set one first target part 31A and one second target part 31B circumferentially at intervals in the first mating section D1, wherein the first target part 31A and the second target part 31B are symmetrically arranged one to one, that is, the first rotating part 3 has two first recesses 31 in the rotation state, so that the hanging support 1 can be rotated and engaged along 180 degrees.

[0121] The second configuration can be that two first target parts 31A and two second target parts 31B are set circumferentially at intervals in the first mating section D1, wherein the first target parts 31A and the second target parts 31B are symmetrically arranged one by one, that is, four first recesses 31 are distributed in the first rotating part 3 in the rotation state, so that the hanging support 1 can be rotated and engaged along 90 degrees.

[0122] The third configuration can be that three first target parts 31A and three second target parts 31B are set circumferentially at intervals in the first mating section D1. The first target parts 31A and the second target parts 31B are symmetrically arranged one by one. That is, there are six first recesses 31 in the first rotating part 3 in the rotation state. In this way, the hanging support 1 can be rotated and engaged along 60 degrees.

[0123] In some embodiments, the first target portion 31A and the second target portion 31B are alternately arranged along the circumference of the first rotating member 3. Alternatively, along the circumference of the first rotating member 3, two second target portions 31B are provided between two adjacent first target portions 31A.

[0124] Specifically, by alternating the arrangement of the first target part 31A and the second target part 31B along the circumference of the first rotating member 3, or by setting two second target parts 31B between two adjacent first target parts 31A, the first abutting member 42 will switch between the engagement state of the first target part 31A and the second target part 31B when the user operates the hanging member 1 to rotate, thus improving the user's operating experience.

[0125] For example, alternating deployment can be cross-substitution.

[0126] In some embodiments, the orthographic projection of at least one first recess 31 onto the reference plane is an arc, and the reference plane is perpendicular to the axial direction of the first rotating member 3. Alternatively, the orthographic projection of at least one first recess 31 onto the reference plane is a broken line, and the reference plane is perpendicular to the axial direction of the first rotating member 3.

[0127] For details, please refer to Figures 1 to 3 The present application defines a reference surface, which is perpendicular to the axial direction of the first rotating member 3. The orthographic projection of at least one first recess 31 onto the reference surface is an arc, which can be a single minor arc or a combination of multiple arcs. The orthographic projection of the first recess 31 onto the reference surface is a broken line, which can be formed by connecting multiple broken lines, such as a "V" shaped broken line or a trapezoidal broken line. The above line segments are only required to have concave openings and be able to engage with the first abutment member 42; no specific limitations are imposed here. By setting different line segments, the first recess 31 and the first abutment member 42 have different rotational feel during rotation, and an engaging effect is achieved during the engagement of the first abutment member 42 and the first recess 31. This improves the looseness problem caused by the hanging bracket 1 when hanging curtains, thereby enhancing the overall stability of the device.

[0128] In some embodiments, the first base 2 is provided with at least one first limiting channel N1 corresponding to at least one first elastic component 4. The first limiting channel N1 has a first opening T1 facing the outer peripheral wall of the first mating section D1. The first elastic member 41 is disposed in the corresponding first limiting channel N1, and at least a portion of the first abutting member 42 can extend out of the first limiting channel N1 through the first opening T1 of the corresponding first limiting channel N1.

[0129] In this application, the first limiting channel N1 serves to accommodate and limit the first elastic component 4. Here, the first limiting channel N1 can be a channel defining the space between the clamp and the first seat 2 to accommodate the first elastic component 4, a cavity provided in the first seat 2, or a blind hole provided in the first seat 2. A portion of the first abutment member 42 can be less than half the volume of the first abutment member 42.

[0130] For details, please refer to Figures 4 to 7The first seat 2 is provided with a first limiting channel N1, and the first elastic component 4 is installed in the first limiting channel N1. The first limiting channel N1 has a first opening T1 facing the outer peripheral wall of the first mating section D1. One end of the first elastic member 41 is disposed in the first limiting channel N1, and the other end elastically abuts against the first abutting member 42, so that at least part of the first abutting member 42 extends out of the first limiting channel N1 through the first opening T1, or the first abutting member 42 is engaged with the first opening T1, and part of the first abutting member 42 extends out of the first limiting channel N1. When the first rotating member 3 rotates, the first abutting member 42 can extend out of the first limiting channel N1 due to the elastic force and engage with the first recess 31. When the hanging member 1 hangs the curtain, since the curtain has weight when it is hung, a locking structure is required to prevent the hanging member 1 from loosening when it rotates. Therefore, through this setting, the hanging member 1 has good stability when hanging the curtain and is not easy to loosen.

[0131] In some embodiments, the first base 2 includes a first portion 21 and a second portion 22 mounted on the first portion 21. The opposing sides of the first portion 21 and the second portion 22 together define a first limiting channel N1. Alternatively, the first limiting channel N1 is disposed in the first portion 21. Alternatively, the first limiting channel N1 is disposed in the second portion 22.

[0132] In this application, the first part 21 can be the seat of the first seat 2, and the second part 22 is a component installed in the seat (such as the component with the first elastic component 4 mentioned above). The first part 21 and the second part 22 are opposite to each other and can jointly define the first limiting channel N1. The first limiting channel N1 can be provided in the first part 21 or in the second part 22.

[0133] For details, please refer to Figures 4 to 7 The combination of the first seat 2 and the first limiting channel N1 is provided. The first limiting channel N1 can be defined by the first part 21 or by the first part 21 together, or the first limiting channel N1 can be provided at the first part 21 or the first part 21, as long as it can accommodate the first elastic component 4 and limit the first elastic component 4. Since when the first elastic member 41 provides elastic force, it is better to have one end fixed and the other end elastically expandable. Thus, by providing the first limiting channel N1, one end of the first elastic member 41 is fixed and the other end abuts against the first abutting member 42. In this way, when the first rotating member 3 rotates, the first abutting member 42 can expand and contract within the first opening T1, so that the first rotating member 3 will not be unable to rotate due to the setting of the first spacing part 32.

[0134] In some embodiments, the first part 21 and the second part 22 are detachably connected.

[0135] For details, please refer to Figures 4 to 7 The first part 21 and the second part 22 are detachably connected. The detachable connection can be a snap-fit, a threaded connection or a plug-in connection. With this setting, when assembling the first elastic member 41 and the first abutting member 42, the user can insert them into the first limiting channel N1 and quickly complete the assembly, thus improving the assembly efficiency of the device.

[0136] In some embodiments, the first part 21 is provided with a snap-fit ​​portion 211, and the second part 22 snaps into the first part 21 by means of the snap-fit ​​portion 211.

[0137] In this application, the snap-fit ​​portion 211 may be part of the protrusion of the first portion 21, for example, the first portion 21 may have a protruding cavity, groove or limiting wall.

[0138] For details, please refer to Figures 4 to 7 The combination of the two parts, through the snap-fit ​​between the second part 22 and the first part 21, ensures that when the first rotating part 3 rotates, the first elastic component 4 located in the first limiting channel N1 will not rotate with the first rotating part 3, thus improving the structural rationality of this application.

[0139] In some embodiments, the first portion 21 is provided with a first mounting hole K1 opened along the axial direction of the first rotating member 3. The first portion 21 has a first side and a second side disposed opposite to each other along the axial direction of the first rotating member 3. The second portion 22 is located on the first side of the first portion 21. The first rotating member 3 includes a first mating section D1 and a mounting section Z1 disposed along the axial direction of the first rotating member 3. The first mating section D1 is located on the first side of the first portion 21, and the mounting section Z1 extends through the first mounting hole K1 to the second side of the first portion 21. The mounting section Z1 is connected to the hanger 1.

[0140] In this application, the first mounting hole K1 can be a through hole, which serves to provide mounting space for the first rotating member 3. The mounting section Z1 is a part of the first rotating member 3 and serves to directly or indirectly connect to the bracket 1.

[0141] For details, please refer to Figures 4 to 9 The first rotating part 3 has a first mounting hole K1 in its axial direction. The first rotating part 3 has a first mating section D1 and a mounting section Z1 in its axial direction. The first rotating part 3 has a first mating section D1 located on the first side of the first part 21. In this way, the first seat 2 can accommodate the first mating section D1, making the overall device more compact.

[0142] Mounting section Z1 extends through the first mounting hole K1 to the second side of the first part 21. Mounting section Z1 connects to the hanger 1. Mounting section Z1 can be directly or indirectly connected to the hanger 1. Indirect connection in this application refers to connection via other components. By providing mounting section Z1, connection space for hanger 1 is provided. When it is necessary to replace different hangers 1, hangers 1 can be pulled out and replaced through mounting section Z1, improving assembly efficiency.

[0143] In some embodiments, multiple first elastic components 4 are provided. All first elastic components 4 are symmetrically arranged on one side of the outer peripheral wall of the first mating section D1 relative to the rotation axis of the first rotating member 3. The first elastic member 41 is a spring, and the first abutting member 42 is a spherical member.

[0144] For details, please refer to Figures 4 to 9 In this combination, multiple first elastic components 4 can be provided. All first elastic components 4 are symmetrically arranged on one side of the outer peripheral wall of the first mating section D1 relative to the rotation axis of the first rotating member 3. Each first elastic component 4 corresponds to a first recess 31. The first elastic component 41 can be a spring, such as a cylindrical helical spring, and the first abutment 42 can be a spherical component. With this arrangement, during the switching between the first state and the second state of the first recess 31, the end face of the spherical component and the first recess 31 are arc-shaped, making it easier for the user to rotate the hanging bracket 1 and improving the user experience.

[0145] In some embodiments, the fixing device further includes a connecting mechanism 5. The connecting mechanism 5 is connected to the first rotating member 3, and the hanging member 1 is rotatably connected to the connecting mechanism 5.

[0146] In this application, the connecting mechanism 5 can be used as the connecting mechanism 5 between the first rotating member 3 and the hanging member 1, and is used to increase the rotational orientation of the hanging member 1.

[0147] For details, please refer to Figures 10 to 14 In addition to the combination of the two components, the fixing device may also include a connecting mechanism 5, which may be located on one side of the first base 2. The connecting mechanism 5 is connected to the first rotating member 3, and the hanging bracket 1 is rotatably connected to the connecting mechanism 5. By providing the connecting mechanism 5, the user can rotate the connecting mechanism 5 to change the primary position of the hanging bracket 1. When multiple positions are required, the hanging bracket 1 can be rotated according to actual needs to achieve a secondary position change. Through this setting, the hanging bracket 1 can be rotated to be closer to the wall according to the coordination of the primary and secondary positions, thereby improving the utilization rate of the usable space.

[0148] For example, the primary orientation and the secondary orientation refer to the orientation of the connecting mechanism 5 and the hanging member 1 before they rotate. The primary orientation may be different from the secondary orientation. For example, the primary orientation may be the circumferential rotation orientation along the rotation axis of the first rotating member 3, and the secondary orientation may be the circumferential rotation orientation perpendicular to the rotation axis of the first rotating member 3.

[0149] For example, the utilization rate of the space can be the percentage of the space effectively utilized after the hanging bracket 1 is rotated out of the total space.

[0150] In some embodiments, the rotation axis of the hanging bracket 1 and the rotation axis of the first rotating member 3 intersect each other.

[0151] For details, please refer to Figures 10 to 14 The rotation axis of the hanging bracket 1 can intersect with the rotation axis of the first rotating component 3. It can be understood that by the intersection (i.e., non-coincidence) of the rotation axis of the hanging bracket 1 with the rotation axis of the first rotating component 3, the hanging bracket 1 can rotate in multiple directions, thereby increasing the diversity of the rotation directions of the hanging bracket 1.

[0152] In some embodiments, the rotation axis of the hanging bracket 1 and the rotation axis of the first rotating member 3 are perpendicular to each other.

[0153] For details, please refer to Figures 10 to 14 The rotation axis of the hanging support 1 can be perpendicular to the rotation axis of the first rotating member 3, which allows the hanging support 1 to rotate along the rotation axis of the first rotating member 3 or along the rotation axis of the support member, thereby increasing the diversity of the rotation direction of the hanging support 1.

[0154] In some embodiments, the connecting mechanism 5 includes a second seat 51 connected to the first rotating member 3. The second rotating member 52 is connected to the hanging member 1 and rotatably connected to the second seat 51. The second rotating member 52 includes a second mating section D2, and a plurality of second recesses 521 are provided at circumferential intervals on the outer peripheral wall of the second mating section D2. At least one second elastic component 53 is also included, comprising a second elastic member 531 and a second abutting member 532, which are disposed on one side of the outer peripheral wall of the second mating section D2. The second elastic member 531 engages between the second seat 51 and the second rotating member 52, such that the second abutting member 532 abuts against the outer peripheral wall of the second mating section D2.

[0155] In this application, the second base 51 can be connected to the first rotating member 3 as a connector and also serves to limit the position of the second elastic component 53. To prevent positional displacement when the second elastic component 531 abuts against the second abutting member 532, the second base 51 can thus limit the position of the second elastic component 53. The second rotating member 52 can be rotatably connected to the hanging member 1 and rotatably connected to the second base 51, allowing the hanging member 1 to rotate during use. The second rotating member 52 can be a shaft, cylinder, etc. Here, the second rotating member 52 can be directly or indirectly connected to the hanging member 1. The second mating section D2 can be a part of the second rotating member 52, allowing the second rotating member 52 to avoid the space provided by the second recess 521. The function of the second recess 521 in cooperating with the second abutting member 532 is to engage / lock with the second abutting member, thereby achieving a locking effect and improving the stability of the hanging member 1. The second elastic member 531 can serve as an elastic force to provide the second abutting member 532, so that the second abutting member 532 can elastically abut against the outer peripheral wall of the second mating section D2.

[0156] The second elastic component 53 includes a second elastic element 531 and a second abutting element 532. It can provide elastic force for the second elastic element 531. The second abutting element 532 abuts or engages with the second recess 521 of the second rotating element 52 due to the elastic force, so that the second rotating element 52 has a locking function when it rotates to the target position (the position to which the hanging bracket 1 rotates according to the usage requirements), which improves the loosening of the hanging bracket 1 connected to the second rotating element 52 and returns it to the initial position (the position before the hanging bracket 1 rotates).

[0157] For details, please refer to Figures 10 to 14 The connecting mechanism 5 includes a second base 51, a second rotating member 52, and at least one second elastic component 53. The second base 51 is connected to the first rotating member 3; the connection can be a detachable connection, such as a snap-fit ​​connection, a plug-in connection, or a threaded connection. The second rotating member 52 is connected to the hanging bracket 1 and rotatably connected to the second base 51. It is understood that by connecting the second rotating member 52 to the hanging bracket 1 and rotatably connecting it to the second base 51, the rotatable connection can be a plug-in connection, a shaft-hole fit connection, or a pivot connection, etc., allowing the user to rotate the hanging bracket 1 to the target position, thereby improving the ease of operation of the hanging bracket 1.

[0158] Furthermore, when the hanging bracket 1 is not needed, the hanging bracket 1, the second rotating component 52, the second elastic component 53, the second base 51, the first elastic component 4, the first rotating component 3, and the first base 2 can work together to rotate the end of the hanging bracket 1 closer to the wall. This arrangement is more versatile than the arrangement of only the hanging bracket 1, the first elastic component 4, the first rotating component 3, and the first base 2. It not only reduces the risk of the end of the hanging bracket 1 tearing clothing and human skin, improving safety, but also has greater applicability.

[0159] Please refer to the following for further information. Figures 10 to 14 The second rotating member 52 includes a second mating section D2, which can be a part of the second rotating member 52. Multiple second recesses 521 are spaced circumferentially along the outer peripheral wall of the second mating section D2. These multiple second recesses 521 can be fitted onto the outer peripheral wall of the second rotating member 52 or integrally formed with it. By circumferentially spaced the multiple second recesses 521 on the outer peripheral wall of the second mating section D2, when the hanging member 1 drives the second rotating member 52 to rotate, the multiple second recesses 521 located in the second mating section D2 can rotate accordingly. This arrangement results in a compact structure, reduces rotational force loss, and thus improves rotational efficiency.

[0160] At least one second elastic component 53 is provided, comprising a second elastic element 531 and a second abutting element 532, which are disposed on one side of the outer peripheral wall of the second mating section D2. The second elastic element 531 is fitted between the second seat 51 and the second rotating member 52, such that the second abutting element 532 abuts against the outer peripheral wall of the second mating section D2. It is understood that the second elastic element 531 can provide an elastic force, and the second abutting element 532 abuts or engages with the second recess 521 of the second rotating member 52 due to the elastic force, so that the second rotating member 52 has a locking effect when rotated to the target position, which improves the return of the hanging support 1 connected to the second rotating member 52 to the initial position due to loosening, and improves the operational stability of this fixing device.

[0161] Accordingly, in the device of this application, a connecting mechanism 5 is provided, in which the hanging bracket 1, the second rotating member 52, the second elastic component 53, the second seat 51, the first elastic component 4, the first rotating member 3, and the first seat 2 cooperate and coordinate with each other, so that the end of the hanging bracket 1 rotates to be close to the wall. This arrangement is more versatile than the arrangement of only the hanging bracket 1, the first elastic component 4, the first rotating member 3, and the first seat 2. It not only reduces the risk of the end of the hanging bracket 1 tearing clothes and human skin, improving the safety of use, but also has greater applicability.

[0162] For example, the second seat 51 may limit the second elastic component 53 by having a cavity inside the second seat 51 to limit the second elastic component 53, a blind hole to limit the second elastic component 53, or a pipe clamp to limit the second elastic component 53; no limitation is made here.

[0163] For example, the second elastic element 531 may be a cylindrical helical spring, a conical spring, or a rectangular spring.

[0164] For example, the second abutment 532 may be a steel ball, ball bearing, tapered roller, spherical object, or needle roller.

[0165] For example, the shape of the second recess 521 can match that of the second abutment 532. For instance, if the second abutment 532 is a ball bearing, the shape of the second recess 521 can be an arc-shaped recess. Alternatively, if the second abutment 532 is a tapered roller, the shape of the second recess 521 can be a tapered recess. Or, if the second abutment 532 is a needle roller, the shape of the second recess 521 can be a cylindrical recess that matches the needle roller. It is understood that appropriate configurations can be adopted depending on the actual mating conditions.

[0166] For example, the rotation axis of the first rotating member 3 can be set perpendicular to the second rotating member 52. With this setting, the rotation direction of the connecting mechanism 5 can be different from the rotation direction of the hanging member 1, so as to realize the multi-directional rotation of the device and make it more applicable.

[0167] In some embodiments, a second spacer 522 is defined between two adjacent second recesses 521 along the circumferential direction of the second rotating member 52. The fixing device has a third state in which the second abutment 532 abuts against the second spacer 522, and a fourth state in which the second abutment 532 abuts against the second recesses 521. The fixing device is capable of switching between the third and fourth states in response to rotation of the second rotating member 52 relative to the second seat 51.

[0168] In this application, the second spacer 522 can be a protruding connecting portion between two adjacent second recesses 521. Its function is to form an abutment wall by means of the second spacer 522 and the second recesses 521 being adjacent, so that the second abutment 532 and the second recesses 521 can be engaged. The second abutment 532 can be located between adjacent abutment walls, which reduces the occurrence of loosening when the second rotating member 52 rotates to the target position and improves the stability of the overall device.

[0169] The second abutting member 532 abutting against the outer surface of the second spacer 522 can be in a third state, and the second abutting member 532 abutting against the second recess 521 can be in a fourth state.

[0170] Please refer to Figures 10 to 14The second rotating member 52 is combined with the second spacer 522. A second spacer 522 can be provided between two adjacent second recesses 521 along the circumference of the second rotating member 52. The straight-line distance of the outer surface of the second spacer 522 along the axis of the second rotating member 52 can be greater than the straight-line distance of the inner surface of the recess along the axis of the second rotating member 52. The fixing device has a third state in which the second abutting member 532 abuts against the second spacer 522, and a fourth state in which the second abutting member 532 abuts against the second recess 521. The second rotating member 52 can switch between the third and fourth states during its rotation relative to the second seat 51. With this configuration, by rotating the hanging bracket 1, the user can rotate the second recess 521 in the second rotating member 52 connected to the hanging bracket 1 to engage with the second abutting member 532 at multiple angles, improving the existing situation where the hanging bracket 1 cannot rotate, and enhancing the convenience of operation and the feel of use.

[0171] In some embodiments, the opening area of ​​the second recess 521 has various values. The central axis of the opening of the second recess 521 and the rotation axis of the second rotating member 52 are perpendicular to each other.

[0172] In this application, the opening area of ​​the second recess 521 can be varied. "Various" here refers to the fact that it can have various shapes, such as an arc-shaped recess, a conical recess, or a cylindrical recess. Correspondingly, the shape of the second abutment 532 can also be varied. The second recess 521 only needs to match the shape of the second abutment 532; no limitation is made here. The centerline of the opening of the second recess 521 can be a symmetrical centerline along the direction of the opening of the second recess 521 and the rotation axis of the second rotating member 52. The rotation axis of the second rotating member 52 refers to the central rotation axis of the second rotating member 52.

[0173] For details, please refer to Figures 10 to 14 The center line of the opening of the second recess 521 and the rotation axis of the second rotating member 52 are perpendicular to each other. The opening of the second recess 521 is defined by the inner wall of the second recess 521 and the outer peripheral wall of the second mating section D2. By adopting an orthogonal arrangement, it is convenient for installers to directly assemble the second abutment member 532 with the second recess 521 by pressing, which improves the assembly efficiency of this device.

[0174] In some embodiments, all second recesses 521 include a plurality of third target portions 521A and a plurality of fourth target portions 521B, wherein the opening area of ​​the third target portion 521A is larger than the opening area of ​​the fourth target portion 521B. The plurality of third target portions 521A and the plurality of fourth target portions 521B are arranged circumferentially along the second rotating member 52.

[0175] In this application, the third target portion 521A or the fourth target portion 521B can be one of the second recesses 521. Alternatively, the third target portion 521A can be another second recess 521 that is different from the fourth target portion 521B, for example, by the difference in the opening area of ​​the recesses. Both the third target portion 521A and the fourth target portion 521B can serve as the parts that abut / lock with the second abutting member 532.

[0176] For details, please refer to Figures 10 to 14 The combination of multiple third target parts 521A and multiple fourth target parts 521B is arranged circumferentially on the outer peripheral wall of the second mating section D2 of the second rotating part 52. The opening area of ​​the third target part 521A can be larger than the opening area of ​​the fourth target part 521B. In this way, when the user rotates the hanging bracket 1, the rotation angle can be accurately judged, thereby improving the accuracy and versatility of operation.

[0177] The fourth configuration can be that a third target part 521A and a fourth target part 521B are set circumferentially in the second mating section D2, wherein the third target part 521A and the fourth target part 521B are symmetrically arranged one to one, that is, the second rotating part 52 has two second recesses 521 in the rotation state, so that the hanging support 1 can be rotated and engaged along 180 degrees.

[0178] The fifth configuration can be that two third target parts 521A and two fourth target parts 521B are set circumferentially in the second mating section D2, wherein the third target parts 521A and the fourth target parts 521B are symmetrically arranged one by one, that is, four second recesses 521 are distributed in the second rotating part 52 in the rotation state, so that the hanging support 1 can be rotated and engaged along 90 degrees.

[0179] Configuration method six can be that three third target parts 521A and three fourth target parts 521B are set circumferentially in the second mating section D2, wherein the third target parts 521A and the fourth target parts 521B are symmetrically arranged one by one, that is, there are six second recesses 521 in the rotation state of the second rotating part 52, so that the hanging support 1 can be rotated and engaged along 60 degrees.

[0180] In some embodiments, the third target portion 521A and the fourth target portion 521B are alternately arranged along the circumference of the second rotating member 52. Alternatively, along the circumference of the second rotating member 52, two fourth target portions 521B are provided between two adjacent third target portions 521A.

[0181] For details, please refer to Figures 10 to 14The combination of the third target part 521A and the fourth target part 521B is arranged alternately along the circumference of the second rotating member 52, or two fourth target parts 521B are provided between two opposite third target parts 521A. In this way, when the user operates the hanging member 1 to rotate, the second abutment member 532 will switch between the engagement state of the third target part 521A and the fourth target part 521B, thereby improving the user's operating experience.

[0182] For example, alternating arrangements can be either mutually replacing arrangements or mutually spaced arrangements.

[0183] In some embodiments, the orthographic projection of at least one second recess 521 onto the reference surface is an arc, and the reference surface is perpendicular to the axial direction of the second rotating member 52. Alternatively, the orthographic projection of at least one second recess 521 onto the reference surface is a broken line, and the reference surface is perpendicular to the axial direction of the second rotating member 52.

[0184] For details, please refer to Figures 10 to 14 The present application defines a reference surface, which is perpendicular to the axial direction of the second rotating member 52. The orthographic projection of at least one second recess 521 onto the reference surface is an arc, which can be a single minor arc or a combination of multiple arcs. The orthographic projection of the second recess 521 onto the reference surface is a broken line, which can be formed by connecting multiple broken lines, such as a "V" shaped broken line or a trapezoidal broken line. The above line segments are only required to have concave openings and be able to engage with the second abutment member 532; no specific limitations are imposed here. By setting different line segments, the second recess 521 and the second abutment member 532 have different rotational feel during rotation, and an engaging effect is achieved during the engagement of the second abutment member 532 and the second recess 521. This improves the looseness problem that occurs when the hanging bracket 1 hangs curtains, thereby enhancing the overall stability of the device.

[0185] In some embodiments, the second rotating member 52 includes a second mating section D2 and a third mating section D3 arranged along the axial direction of the second rotating member 52. The outer peripheral wall of the third mating section D3 is provided with a recessed portion 523 arranged around the rotation axis of the second rotating member 52. The connecting mechanism 5 also includes a limiting member 54. The limiting member 54 is disposed on the second seat 51, and one end of the limiting member 54 is accommodated in the recessed portion 523.

[0186] In this application, the third mating section D3 can be a portion of the second rotating member 52 that is far from the second mating section D2, serving to create space for the recessed portion 523. The limiting member 54 can be a cylinder, a pin, or a locking block, serving to be positioned against the recessed portion 523 and to limit the second rotating member 52, preventing it from detaching from the second seat 51. The recessed portion 523 can be an annular groove, serving to abut against the limiting member 54, making it difficult for the second rotating member 52 to detach from the second seat 51 during rotation.

[0187] For details, please refer to Figures 10 to 14 The second rotating member 52 is provided with a second mating section D2 and a third mating section D3. The outer peripheral wall of the third mating section D3 is provided with a recessed portion 523 arranged around the rotation axis of the second rotating member 52. The connecting mechanism 5 also includes a limiting member 54. The second seat 51 may be provided with a through hole or a blind hole. The limiting member 54 is provided in the through hole or blind hole of the second seat 51, and one end of the limiting member 54 is accommodated in the recessed portion 523. Through this arrangement, since the limiting member 54 is provided in the second seat 51 and one end can abut against the recessed portion 523, the second rotating member 52 is not easy to disengage from the second seat 51 when rotating, thus reducing the failure rate of this application.

[0188] In some embodiments, the recess 523 is configured as an annular structure. One end of the limiting member 54 abuts against the recess 523, and when the second rotating member 52 rotates relative to the second seat 51, the limiting member 54 abuts against the recess 523, and the limiting member 54 is engaged with the recess 523.

[0189] For details, please refer to Figures 10 to 14 The recessed portion 523 can be a ring structure, and one end of the limiting member 54 abuts against the recessed portion 523. When the second rotating member 52 rotates relative to the second seat 51, the limiting member 54 makes it difficult for the second rotating member 52 to disengage from the second seat 51, thereby reducing the failure rate of this application.

[0190] For example, the second seat 51 may be provided with a third limiting channel N3 for accommodating the limiting member 54, and the third limiting channel N3 may be a through hole or a blind hole.

[0191] In some embodiments, the second base 51 is provided with an installation channel W, and at least a portion of the second rotating member 52 is rotatably inserted into the installation channel W.

[0192] In this application, the mounting channel W can be a blind hole or a through hole, which serves to accommodate the second rotating member 52.

[0193] Specifically, the second base 51 is provided with an installation channel W, and at least a portion of the second rotating member 52 is rotatably inserted into the installation channel W. This arrangement makes the structure of the device more compact.

[0194] In some embodiments, the second seat 51 is provided with at least one second limiting channel N2 corresponding to at least one second elastic component 53. The second limiting channel N2 has a second opening T2 facing the outer peripheral wall of the second mating section D2. The second elastic component 531 is disposed in the corresponding second limiting channel N2, and at least a portion of the second abutting component 532 can extend out of the first limiting channel N1 through the second opening T2 of the corresponding second limiting channel N2.

[0195] In this application, the second limiting channel N2 is used to accommodate the second elastic component 53 and limit its movement. Here, the second limiting channel N2 can be a channel defining the space between the clamp and the second seat 51 to accommodate the second elastic component 53, a cavity provided in the second seat 51, or a blind hole provided in the first seat 2. The second opening T2 is used as an opening for the second limiting channel N2 facing the outer peripheral wall of the second mating section D2. Its function is to allow a portion of the second abutment 532 to extend out of the space of the second limiting channel N2, and to achieve abutment with the second recess 521.

[0196] For details, please refer to Figures 10 to 14 The second elastic component 53 is installed in the second limiting channel N2. The second limiting channel N2 is provided with a second opening T2 near the second rotating member 52. At least part of the second abutting member 532 can extend out of the second limiting channel N2 through the corresponding second opening T2 and abut against the second recess 521. In this way, when the second rotating member 52 rotates, the second abutting member 532 can extend out of the second limiting channel N2 due to the elastic force and engage with the second recess 521. When the hanging member 1 hangs the curtain, since the curtain has weight when it is hung, a locking structure is required to prevent the hanging member 1 from loosening when it rotates. Therefore, through this setting, the hanging member 1 has good stability when hanging the curtain and is not easy to loosen.

[0197] In some embodiments, the first rotating member 3 is detachably connected to the second seat 51. The fixing device also includes a protective assembly, which includes a first protective member 6 and a second protective member 7. Along the axial direction of the first rotating member 3, the first protective member 6 is detachably connected to the side of the first seat 2 facing the second seat 51, and the second protective member 7 is detachably connected to the side of the second seat 51 facing the first seat 2. The first protective member 6 and the second protective member 7 are in contact. Through this arrangement, the cooperation between the first protective member 6 and the second protective member 7 reduces friction, making the rotation of the hanging member 1 smoother.

[0198] It is understandable that when the second port T2 and the third limiting channel N3 are set as through holes, the second protective member 7 is also provided, which can abut against one end of the second elastic member 531 and the limiting member 54, reducing the occurrence of the second elastic member 531 and the limiting member 54 falling off.

[0199] In some embodiments, the fixing device further includes a fastener 8, which is connected to the first seat 2 and the first port T1 and is detachably connected to the connecting mechanism 5.

[0200] For example, the detachable connection can be a threaded connection.

[0201] Please refer to the following in this application: Figures 10 to 14 The combination of the two components reduces the friction generated by the rotation of the first base 2 and the second base 51, and improves the durability of the device. The protective component includes a first protective element 6 and a second protective element 7. The first protective element 6 can be a gasket (existing technology), and the second protective element 7 can be a metal baffle. The metal baffle can be made of iron, steel, or alloy metals, etc. The metal can be an existing material, which will not be described in detail here.

[0202] Specifically, the connection between the first rotating member 3 and the second seat 51 can be a detachable connection such as a plug-in or snap-fit. Along the axial direction of the first rotating member 3, a first protective member 6 is provided on the side of the first seat 2 facing the second seat 51, and a second protective member 7 is detachably connected to the side of the second seat 51 facing the first seat 2, wherein the first protective member 6 and the second protective member 7 are in contact. This arrangement reduces the frictional force generated when the first seat 2 and the second seat 51 rotate relative to each other and improves the durability of the overall device.

[0203] In some embodiments, the second limiting channel N2 and the mounting channel W are through holes. The second protective member 7 can abut against the side of the second limiting channel N2 and the third limiting channel N3 away from the second rotating member 52, and limit the second elastic component 53 disposed in the second limiting channel N2, and limit the limiting member 54 disposed in the third limiting channel N3. This arrangement facilitates the assembly of the second elastic component 53 and the limiting member 54, improving assembly efficiency.

[0204] For example, the second seat 51 is provided with a second protective member 7 mounting cavity along the side of the second seat 51 facing the first seat 2, and the second protective member 7 is disposed in the second protective member 7 mounting cavity.

[0205] For example, the materials of each component in this application can be: the first base 2 can be made of aluminum alloy or zinc alloy; the first protective component 6 can be made of existing materials; the second protective component 7 can be made of iron, steel, or alloy; the second base 51 can be made of aluminum alloy or zinc alloy; the first rotating component 3 can be made of aluminum alloy or zinc alloy; the second rotating component 52 can be made of aluminum alloy or zinc alloy; and the hanging bracket 1 can be made of steel, aluminum alloy, iron, or plastic.

[0206] In some embodiments, the fixing device provided in this application includes a hanger 1, a first base 2, a first rotating member 3, and at least one first elastic component 4. The first base 2 is fixedly connected to the mounting structure (e.g., a wall or wall column). The first rotating member 3 is connected to the hanger 1 and rotatably connected to the first base 2. Multiple first recesses 31 are spaced circumferentially along the outer peripheral wall of the first mating section D1 of the first rotating member 3. There can be four first recesses 31. All first elastic components 4 are disposed within the first base 2. Each first elastic component 4 includes a first elastic member 41 and a first abutting member 42. The first elastic member 41 and the first abutting member 42 are disposed on one side of the outer peripheral wall of the first mating section D1. The first elastic member 41 abuts against one end of the first abutting member 42, and the first abutting member 42 abuts against the outer peripheral wall of the first mating section D1 due to elastic force. Thus, the user can rotate the hanger 1, causing it to rotate along the axis of the first rotating member 3, and locking at 90-degree intervals.

[0207] In some embodiments, the fixing device provided in this application includes a hanger 1, a first base 2, a first rotating member 3, and at least one first elastic component 4. The first base 2 is fixedly connected to the mounting structure (e.g., a wall or wall column). The first rotating member 3 is connected to the hanger 1 and rotatably connected to the first base 2. A plurality of first recesses 31 are provided on the outer peripheral wall of the first mating section D1 of the first rotating member 3 along the circumferential direction of the first rotating member 3. The first recesses 31 include a plurality of first target portions 31A and a plurality of second target portions 31B. There are 3 first target portions 31A and 3 second target portions 31B. All the first elastic components 4 are disposed in the first base 2. The first elastic component 4 includes a first elastic member 41 and a first abutting member 42. The first elastic member 41 and the first abutting member 42 are disposed on one side of the outer peripheral wall of the first mating section D1. The first elastic member 41 abuts against one end of the first abutting member 42. The first abutting member 42 abuts against the outer peripheral wall of the first mating section D1 due to elastic force. In this way, the user can rotate the hanging bracket 1, so that the hanging bracket 1 rotates along the axis of the first rotating member 3, and has a locking function at 60-degree intervals.

[0208] In some embodiments, the fixing device provided in this application includes a hanger 1, a first base 2, a first rotating member 3, and at least one first elastic component 4. The first base 2 is fixedly connected to the mounting structure (e.g., a wall or wall column), and the first rotating member 3 is rotatably connected to the first base 2. A plurality of first recesses 31 are provided at intervals along the circumference of the first rotating member 3 on the outer peripheral wall of the first mating section D1 of the first rotating member 3. There can be two first recesses 31. All the first elastic components 4 are disposed in the first base 2. The first elastic component 4 includes a first elastic member 41 and a first abutting member 42. The first elastic member 41 and the first abutting member 42 are disposed on one side of the outer peripheral wall of the first mating section D1. The first elastic member 41 abuts against one end of the first abutting member 42, and the first abutting member 42 abuts against the outer peripheral wall of the first mating section D1 due to elastic force.

[0209] Furthermore, the fixing device provided in this application embodiment also includes a connecting mechanism 5, which includes a second base 51, a second rotating member 52, and at least one second elastic component 53. The second base 51 is connected to the first rotating member 3, and the second rotating member 52 is connected to the hanging member 1 and rotatably connected to the second base 51. Multiple second recesses 521 are spaced circumferentially along the outer peripheral wall of the second mating section D2 of the second rotating member 52. There can be two second recesses 521. The second elastic component 53 includes a second elastic member 531 and a second abutting member 532. The second elastic member 531 and the second abutting member 532 are located on one side of the outer peripheral wall of the second mating section D2. The second elastic member 531 abuts against one end of the second abutting member 532, and the second abutting member 532 abuts against the outer peripheral wall of the second mating section D2 due to elastic force. In this way, the user can rotate the connecting mechanism 5 to make the hanging bracket 1 rotate along the axis of the first rotating member 3, or rotate the hanging bracket 1 to make it rotate along the axis of the second rotating member 52. Thus, the connecting mechanism 5 has a locking effect every 180 degrees when rotating, and the hanging bracket 1 also has a locking effect every 180 degrees when rotating. It can be understood that the user can drive the connecting mechanism 5 or the hanging bracket 1 according to the specific usage situation, thereby using the hanging bracket 1 to rotate in different directions.

[0210] In some embodiments, the fixing device provided in this application includes a hanger 1, a first base 2, a first rotating member 3, and at least one first elastic component 4. The first base 2 is fixedly connected to the mounting structure (e.g., a wall or wall column), and the first rotating member 3 is rotatably connected to the first base 2. A plurality of first recesses 31 are provided at intervals along the circumference of the first rotating member 3 on the outer peripheral wall of the first mating section D1 of the first rotating member 3. There can be four first recesses 31. All the first elastic components 4 are disposed in the first base 2. The first elastic component 4 includes a first elastic member 41 and a first abutting member 42. The first elastic member 41 and the first abutting member 42 are disposed on one side of the outer peripheral wall of the first mating section D1. The first elastic member 41 abuts against one end of the first abutting member 42, and the first abutting member 42 abuts against the outer peripheral wall of the first mating section D1 due to elastic force.

[0211] Furthermore, the fixing device provided in this application embodiment also includes a connecting mechanism 5, which includes a second base 51, a second rotating member 52, and at least one second elastic component 53. The second base 51 is connected to the first rotating member 3, and the second rotating member 52 is connected to the hanging support 1 and rotatably connected to the second base 51. Multiple second recesses 521 are spaced circumferentially along the outer peripheral wall of the second mating section D2 of the second rotating member 52. There can be four second recesses 521. The second elastic component 53 includes a second elastic member 531 and a second abutting member 532. The second elastic member 531 and the second abutting member 532 are located on one side of the outer peripheral wall of the second mating section D2. The second elastic member 531 abuts against one end of the second abutting member 532, and the second abutting member 532 abuts against the outer peripheral wall of the second mating section D2 due to elastic force. In this way, the user can rotate the connecting mechanism 5 to make the hanging bracket 1 rotate along the axis of the first rotating member 3, or rotate the hanging bracket 1 to make it rotate along the axis of the second rotating member 52. Thus, the connecting mechanism 5 has a locking effect every 60 degrees when rotating, and the hanging bracket 1 also has a locking effect every 60 degrees when rotating. It can be understood that the user can drive the connecting mechanism 5 or the hanging bracket 1 according to the specific usage situation, thereby using the hanging bracket 1 to rotate in different directions.

[0212] In some embodiments, the fixing device provided in this application includes a hanger 1, a first base 2, a first rotating member 3, and at least one first elastic component 4. The first base 2 is fixedly connected to the mounting structure (e.g., a wall or wall column), and the first rotating member 3 is rotatably connected to the first base 2. A plurality of first recesses 31 are provided at intervals along the circumference of the first rotating member 3 on the outer peripheral wall of the first mating section D1. All the first elastic components 4 are disposed in the first base 2. The first elastic component 4 includes a first elastic member 41 and a first abutting member 42. The first elastic member 41 and the first abutting member 42 are disposed on one side of the outer peripheral wall of the first mating section D1, wherein the first elastic member 41 abuts against one end of the first abutting member 42, and the first abutting member 42 abuts against the outer peripheral wall of the first mating section D1 due to elastic force.

[0213] Furthermore, the fixing device provided in this embodiment of the application also includes a connecting mechanism 5, which includes a second base 51, a second rotating member 52, and at least one second elastic component 53. The second base 51 is connected to the first rotating member 3, and the second rotating member 52 is connected to the hanging member 1 and rotatably connected to the second base 51.

The second elastic component 53 includes a second elastic member 531 and a second abutting member 532, which are located on one side of the outer peripheral wall of the second mating section D2. The second elastic member 531 abuts against one end of the second abutting member 532, and the second abutting member 532 abuts against the outer peripheral wall of the second mating section D2 due to elastic force. Thus, the user can rotate the connecting mechanism 5 to rotate the hanging member 1 along the axis of the first rotating member 3, or rotate the hanging member 1 to rotate it along the axis of the second rotating member 52.

[0214] This application also includes a first protective member 6 and a second protective member 7. Along the axial direction of the first rotating member 3, the first protective member 6 is detachably connected to the side of the first seat 2 facing the second seat 51. The second protective member 7 is detachably connected to the side of the second seat 51 facing the first seat 2, and the first protective member 6 and the second protective member 7 are in contact.

[0215] In this way, the user can rotate the connecting mechanism 5 to make the hanging bracket 1 rotate along the axis of the first rotating member 3, or rotate the hanging bracket 1 to make the hanging bracket 1 rotate along the axis of the second rotating member 52. It can be understood that the user can drive the connecting mechanism 5 or the hanging bracket 1 according to the specific usage situation, so as to use the hanging bracket 1 to rotate in different directions.

[0216] It should be noted that the above implementation methods are merely illustrative examples and do not necessarily limit other possible ways of operation in this application.

[0217] The following description, in conjunction with the illustrations in some of the above embodiments, provides an exemplary account of the use of the fixing device provided in this application.

[0218] In one usage scenario, when it is necessary to gather the curtains, the curtains are first hung in the hanging bracket 1. The user can rotate the hanging bracket 1 according to actual needs, so that the hanging bracket 1 rotates to the target position.

[0219] In another usage scenario, when there is no need to gather the curtains, the connecting mechanism 5 and the hanging bracket 1 can be rotated to bring the hanging bracket 1 closer to the wall.

[0220] The technical features of the above embodiments can be combined in any way. For the sake of brevity, not all possible combinations of the technical features in the above embodiments are described. However, as long as there is no contradiction in the combination of these technical features, they should be considered to be within the scope of this specification. It is understood that the above usage is only an illustrative example. Operators can use it according to specific usage needs, and no specific restrictions are imposed here.

[0221] The above embodiments merely illustrate several implementation methods of this application, and their descriptions are relatively specific and detailed. However, they should not be construed as limiting the scope of the patent.
