[0061] In order to enable those skilled in the art to better understand the present application and to more clearly define the scope of the present application, the present application will be described in detail below with respect to certain specific embodiments of the present application. It should be noted that the following is only some specific embodiments of the present application and is only a part of the embodiments of the present application. The specific and direct description of the related structure is only for the convenience of understanding the present application, and each specific feature does not necessarily and directly limit the scope of the present application. Any routine selection and replacement made by those skilled in the art under the guidance of the present application concept should be considered within the scope of the present application.

[0062] The tree top supporting member is used to match the tree top of the Christmas tree, so that the tree top decoration member is fixed to the tree top of the Christmas tree through the tree top supporting member, and the purpose of decorating the Christmas tree is achieved.

[0063] Please refer to Figures 1-3The tree top support includes a support body 100, a support assembly 200 and an adjusting member 300 fitted on the support body 100. The support body 100 is used to cooperate with the tree top of the Christmas tree, so as to fit the tree top support on the tree top of the Christmas tree. The support assembly 200 and the adjusting member 300 are both fitted on the support body 100. The support assembly 200 is pivoted to present different cooperation states for different tree top decorations to be fixed on the tree top of the Christmas tree through the tree top support. The adjusting member 300 is displaceably fitted on the support body 100 to adjust the cooperation state of the support assembly 200 relative to the support body 100.

[0064] The support body 100 includes a support rod 110 in a rod or rod-like structure to provide core support.

[0065] The support assembly 200 includes a plurality of support members 210, each of which is pivotally fitted on the support rod 110. The outer surface of each support member 210 is formed as a support surface 211. Different included angles are formed between each support surface 211 and the support rod 110 due to the pivoting of the support member 210. The support surfaces 211 of the support members 210 are collectively formed as a support surface of the support assembly 200 for the cooperation of the tree top decoration on the support surface. Since the pivoting angle of each support member 210 relative to the support rod 110 is adjustable, the angle of the support surface formed by the support surfaces 211 is also adjustable, so that the tree top support can be adapted to tree top decorations of different shapes or sizes.

[0066] The adjusting member 300 is displaceably arranged along the extension direction of the support rod 110. The adjusting member 300 includes an adjusting portion 310 which is synchronously displaced when the adjusting member 300 is displaced along the support rod 110. The adjusting portion 310 is fitted on the bottom or inner wall of each support member 210 to make the support member 210 pivot relative to the support rod 110. The included angle of the support member 210 relative to the support rod 110 is also correspondingly increased or reduced to form a support structure of different sizes in a conical shape to adapt to the tree top support with a fixed connecting portion in a conical or conical-like shape. In addition, the support member 210 can also be pivoted to be arranged in abutment with the support rod 110 to form a support structure in a cylindrical or prismatic shape, so as to realize the folding storage of the tree top support or serve as a tree top support with a fixed connecting portion in a cylindrical shape or a clamping portion as a fixed connecting portion.

[0067] When the tree top support is adapted to the tree top decoration with different fixed connecting portions, the cooperation process of the two is as follows:

[0068] Please refer to Figure 8As shown, the tree top support member is adjusted to a proper angle by the pivoting of each support member 210 to form a conical support surface, and the adjusting member 300 is rotated to a proper position and kept in the position by the threaded structure relative to the support rod 110, at which time the inner wall of each support member 210 is supported by the adjusting portion 310 of the adjusting member 300. Please refer to Figure 13 As shown, the tree top decoration member 600 has a conical fixed portion formed by the coiling of the linear portion, which is sleeved on the conical support surface of the tree top support member. Obviously, the tree top support member can be adjusted to different conical surface angles by the up and down displacement of the adjusting member 300 on the support rod 110, so as to match various conical fixed portions with different conical surface angles.

[0069] Please refer to Figure 14 As shown, the tree top support member can also be adjusted to the inner portion of the skirt of the doll-shaped tree top support member, so as to realize the fixation of the doll-shaped tree top support member.

[0070] Please refer to Figure 15 As shown, the tree top support member is formed to have a cylindrical upper portion shape when each support member 210 is in the folded storage state, which not only can form the folded state of the tree top support member, but also can fix the tree top decoration member with a cylindrical fixed inner cavity. At this time, the inner diameter of the fixed connecting portion of the cylindrical fixed inner cavity of the tree top decoration member is greater than or equal to the outer diameter at each support member 210, and the lower end of the fixed connecting portion is supported by the adjusting portion 310, so as to realize the fixation of the tree top decoration member 600.

[0071] Please refer to Figure 16 As shown, the tree top support member can also fix the tree top decoration member with a clip as a fixed connecting portion when each support member 210 is in the folded storage state. At this time, the fixed connecting portion of the tree top decoration member 600 is a clip 602, which is clamped on one side on each support member 210 in the folded state, so as to realize the fixation of the tree top decoration member 600.

[0072] Therefore, the tree top support member can match the tree top decoration member 600 with various modeling fixed connecting portions, such as the fixed connecting portion with a conical inner cavity, the skirt fixed connecting portion, the fixed connecting portion with a cylindrical inner cavity, and the clip fixed connecting portion, by the different states formed by the pivoting of each support member 210 relative to the support rod 110.

[0073] In some embodiments, the upper end of each support member 210 is provided with a pivot 201, and a corresponding shaft seat is provided on the support rod 110, and the pivot 201 is fitted in the shaft seat, so that the support member 210 is pivotably arranged with the upper end at a certain position as a pivot.

[0074] Please refer toFigure 3 、 4 The top of the support rod 110 is provided with an axle seat fixing cover 120, which is fixed with the support rod 110 by screws (not shown in the figure). The axle seat fixing cover 120 and the support rod 110 are respectively provided with a half axle seat 202. The two half axle seats 202 arranged on the axle seat fixing cover 120 and the support rod 110 are matched to form an axle seat after the axle seat fixing cover 120 and the support rod 110 are fixed.

[0075] The top of the support rod 110 is also provided with a pivot hole 203, so that the upper part of each support piece 210 is matched therein to form a pivot 201 around the upper end of each support piece 210, which is pivotally matched on the support rod 110.

[0076] Although, in the Figure 5 The axle seat fixing cover 120 and the support rod 110 are fixed by screws, other connection technologies known in the art can also be adapted, such as clamping, gluing, etc.

[0077] Please refer to Figure 2 、 5 In order to lock each support piece 210 when not in use, the upper end surface of the adjusting part 310 is provided with a lock groove 311, and the lower end 212 of each support piece 210 can be matched in the lock groove 311 so that the tree top support piece can form a relatively fixed overall structure when not in use. That is, when each support piece 210 is pivoted to fit on the support rod 110 to form a cylindrical shape, the lower end 212 of each support piece 210 is locked in the lock groove 311, so that each support piece 210 cannot be arbitrarily pivoted.

[0078] Please refer to Figure 5 In order to make each support piece 210 self-pivot to the required angle when adjusting the tree top support piece, the adjusting part 310 is provided with a guide surface 313, which is a conical or curved surface and is inclined from inside to outside to act on the lower end 212 of the support piece 210 to play a guiding role. When the adjusting part 300 is displaced along the support rod 110, for example, from bottom to top, the lower end of the support piece 210 slides along the guide surface 313 to be guided to self-expand.

[0079] In addition, it is also feasible not to provide the guide surface 313 on the adjusting part 310, but only to invert the tree top support part or manually push each support piece 210 during initial adjustment. At this time, the upper surface of the adjusting part 310 can be provided as a flat surface.

[0080] Please refer to Figure 5For the convenience of operating the adjusting member 300, the adjusting member 300 further comprises a hand wheel part 320 arranged below the adjusting part 310. And for the purpose of allowing the adjusting member 300 to be arranged displaceably relative to the extending direction of the support rod 110, the adjusting member 300 is hollow inside to form a cylindrical cavity 312, which can be arranged outside the support rod 110 to allow the adjusting member 300 to displace up and down along the support rod 110.

[0081] In some embodiments, the outer wall of the support rod 110 and the inner wall of the cylindrical cavity 312 are respectively provided with matching thread structures, so that the adjusting member 300 can be displaced or positioned up and down relative to the support rod 110 by rotating. The specific parameters (such as pitch) of the thread structures can be set as needed, so that one rotation of the adjusting member 300 corresponds to an appropriate displacement distance and can be positioned at a corresponding position.

[0082] In other embodiments, the up and down displacement or positioning between the support rod 110 and the adjusting member 300 by thread cooperation is replaced by other equivalent alternative structures.

[0083] For example, the adjusting member 300 is freely displaceably arranged on the support rod 110 and is locked and positioned by a locking mechanism. The locking mechanism comprises a clamping groove 113 and a clamping block (not shown in the figure) arranged on the support rod 110 and the adjusting member 300 respectively. When the clamping block is separated from the clamping groove 113 to be unlocked, the adjusting member 300 can be freely displaced to the desired position along the extending direction of the support rod 110, and the clamping block is matched into the clamping groove 113 to lock the displacement of the adjusting member 300 along the support rod 110, thereby realizing the positioning of the adjusting member 300, so that each support 210 presents the required taper angle.

[0084] The clamping groove is preferably arranged on the outer surface of the support rod 110 along the extending direction thereof, and the adjusting member 300 is correspondingly provided with a clamping block. When the clamping block is matched in the clamping groove, the displacement of the adjusting member 300 relative to the support rod 110 along the extending direction of the support rod 110 is locked and positioned. If it is needed to operate the adjusting member 300 to displace it relative to the support rod 110, the clamping block is separated from the clamping groove by operation, and after being displaced to the appropriate position, the two are matched again to realize relocking. The structure of the clamping block is known, for example, by arranging a elastic rod on the inner wall of the cylindrical cavity 312 at one end and forming a clamping block that can be clamped into the clamping groove at the other end.

[0085] In addition, on the basis that the adjusting member 300 is freely displaced to be sleeved on the support rod 110 and is locked and positioned by the locking mechanism, the outer wall of the support rod 110 and the inner wall 314 of the cylindrical cavity can further be matched by friction, and specifically, the displacement or positioning of the adjusting member 300 along the extending direction of the support rod 110 can be achieved by the interference fit relationship or the elastic sheet matching structure between the inner and outer diameters. Of course, when the friction is large enough, the above-mentioned locking mechanism composed of the clamping groove and the clamping block can be omitted.

[0086] Although the guiding surface 313 can make each support member 210 self-pivot to the required angle by the guiding effect, it is not applicable when the initial unlocking operation is performed. In order to further simplify the operation and improve the user experience, the tree top support member further comprises an unlocking auxiliary member 130 to make the lower end of each support member 210 expand and cooperate with the guiding surface 313 when the initial unlocking operation is performed on each support member 210 to make it pivot to the required angle.

[0087] Please refer to Figure 4 The unlocking auxiliary member 130 is arranged on the support rod 110 at a proper distance below the shaft seat, i.e. below the pivot shaft of each support member 210, wherein the pivot shaft refers to the pivot shaft formed when the support member 210 pivots around the pivot shaft 201. Moreover, the unlocking auxiliary member 130 is arranged protruding from the surface of the support rod 110, so that when each support member 210 is cooperated with the locking groove 311 at the lower end to be locked, the unlocking auxiliary member 130 acts on the inner wall of each support member 210 to make it slightly deform. At this time, if the adjusting member 300 is operated to be displaced downward by a proper distance, the lower end of each support member 210 will be separated from the locking groove 311, and will be pivoted by a small angle to make the lower end slightly expand due to the action of the unlocking auxiliary member 130, forming the initial unlocking state as shown in Figure 6 、 7 .

[0088] Obviously, due to the action of the unlocking auxiliary member 130, the lower end of each support member 210 will be in the cooperating state with the guiding surface 313, and then the adjusting member 300 is further operated to be displaced upward, so as to adjust the pivot angle of each support member 210, and make the support surface formed by the outer surface of each support member 210 meet the use requirements. Such a structure design is undoubtedly positive for the user operation.

[0089] Please refer to Figure 8 In some cases, the tree top support member is adjusted to the use state to fix the tree top decoration by the conical support surface formed by the outer surface of each support member 210. Of course, the conical angle of the conical surface is not limited to the angle shown in Figure 8 , and the conical angle of the conical surface can be adjusted by the upward and downward displacement of the adjusting member 300 on the support rod 110.

[0090] In order to make the tree top support have better use effect and beautiful appearance in the process of storage and use, the cross section of each support 210 is a circular ring shape of about 1 / 4 of a circle, so that the tree top support is formed as a columnar structure as shown in Figure 1 、 2 , which is used as the storage in the non-use state or matches the tree top decoration with a cylindrical, prismatic or other similar shape fixed cavity.

[0091] Of course, the cross section of each support 210 can also be other shapes or arcs, for example, when the cross section of the support rod 110 is a square, the cross section of each support 210 is a rectangular shape and its length is about equal to the length of each side of the support rod 110, so that the overall shape is a cube when each support 210 is pivoted to fit the support rod 110. In addition, the number of supports 210 is not limited to four as shown in the figure, and more or less is also possible; for example, two, three, five, six or more.

[0092] In addition, in order to better match the tree top decoration with a tapered fixed cavity, in the tree top support, the pivot 201 of each support 210 is arranged as close to the top end of the support rod 110 as possible, so that the tree top support has a tapered or tapered shape in the open state.

[0093] In other embodiments, the lower end surface of the support 210 is beveled to better cooperate with the guide surface 313 of the adjusting part 310 during adjustment.

[0094] In other embodiments, the inside of the support rod 110 is hollow to form an inner cavity 11, which includes an upper cavity 111 for the tree top decoration with a linear or rod-shaped fixed connecting part to fit into the upper cavity 111 to achieve fixation of the tree top decoration 600. In addition, the inner cavity 11 is preferably arranged through the upper and lower ends of the support rod 110, thereby forming a lower cavity 112 at the lower end of the support rod 110; when the inner cavity 11 is not arranged through, the upper cavity 111 and the lower cavity 112 are not connected.
