In the following, technical solutions in embodiments of the present application will be described clearly and completely in combination with drawings. Obviously, the embodiments described herein are only a few examples of the present application, not all of the embodiments. Based on the embodiments of the present application, all other embodiments obtained by a person skilled in the art without inventive work will fall into the scope of the present application.
Please refer to
The supporting trunk 11 is provided on the carrying base 10. A plurality of first separated branches 111 are provided on the supporting trunk 11 at intervals, and the first light string 20 is provided on a first separated branch of the plurality of the first separated branches 111. In this embodiment, the supporting trunk 11 is a rod extending upwards from the carrying base 10.
The first connector 13 is provided on a top of the supporting trunk 11. In this embodiment, the top of the supporting trunk 11 is threadedly connected to a bottom of the first connector 13.
A plurality of second separated branches 121 are provided on the top trunk 12, and the second light string 30 is provided on a second separated branch of the plurality of the second separated branches 121. In this embodiment, the top trunk 12 is a rod with its axis parallel to an axis of the supporting trunk 11.
The second connector 14 is provided on a bottom of the top trunk 12. In this embodiment, the bottom of the top trunk 12 is threadedly connected to a top of the second connector 14.
In this embodiment, the second connector 14 is rotationally connected to the first connector 13. An axis of a rotating shaft of the second connector 14 is perpendicular to the axis of the supporting trunk 11. Furthermore, a trigger button 15 is provided between the first connector 13 and the second connector 14 to control rotation of the first connector 13 and the second connector 14.
It should be understood that, the top trunk 12 is used as a top of the Christmas tree. The top trunk 12 is rotationally installed in the first connector 13 of the supporting trunk 11 through the second connector 14. Therefore, when it is needed to decorate the top of the Christmas tree, a height of the top of the Christmas tree may be lowered by rotating the top trunk 12, which is convenient for people to work.
In this embodiment, a first clamping panel 131 and a second clamping panel 132 are extendedly provided on a top of the first connector 13 at intervals. The first clamping panel 131 and the second clamping panel 132 extend toward a direction of the second connector 14. A clamping slot 130 is formed between the first clamping panel 131 and the second clamping panel 132. A protrusion 141 extends from a bottom of the second connector 14, and is rotationally provided within the clamping slot 130. A perforation 1301 connected to the clamping slot 130 is provided on the first clamping panel 131, with an extension direction of the perforation 1301 perpendicular to the axis of the supporting trunk 11. At least a part of the trigger button 15 is inserted in the perforation 1301, and the trigger button 15 may slide along a direction perpendicular to the axis of the supporting trunk 11.
In this embodiment, the trigger button 15 includes a button body 151 inside the perforation 1301 and a button cover 152 connected to the button body 151 and stuck outside the perforation 1301. Wherein, the button body 151 extends along a direction perpendicular to the axis of the supporting trunk 11. A locking part 153 extending toward a direction of the second connector 14 is protrudingly provided at one end of the button body 151 away from the button cover 152. The locking part 153 is used for locking the protrusion 141 in the clamping slot 130. In this embodiment, the button body 151 is disposed on a side near the first clamping panel 131. The button body 151 extends towards the second clamping panel 132 along the direction perpendicular to the axis of the supporting trunk 11. The locking part 153 is disposed on a side near the second clamping panel 132.
Furthermore, an extrusion spring 16 is provided in the perforation 1301. The extrusion spring 16 is used to push the trigger button 15 outward to slide along the direction perpendicular to the axis of the supporting trunk 11. One end of the extrusion spring 16 abuts on an inner side surface of the button cover 152, and the other end of the extrusion spring 16 abuts on an inner side surface of the second clamping panel 132. An elastic force is directed from the second clamping panel 132 to the first clamping panel 131.
In this embodiment, a distance between the inner side surface of the button cover 152 and the sidewall of the second clamping panel 132 of the clamping slot 130 is shorter than a length of the extrusion spring 16 under a normal condition. In this way, under the normal condition, the extrusion spring 16 makes the trigger button 15 tend to move towards the outside of the perforation 1301.
In this embodiment, one end of the protrusion 141 closed to the first connector 13 is arranged in an arc shape. A plurality of locking slots 142 for accommodating the locking part 153 are provided at intervalson a bottom of the protrusion 141 near the first connector 13. The plurality of the locking slots 142 are formed on a side surface of the protrusion 141 facing the second clamping panel 132, and are opposite to the locking part 153. The locking part 153 may be moved away from or inserted into the locking slot 142 along the direction perpendicular to the axis of the supporting trunk 11. When the locking part 153 is inserted into the locking slot 142, the locking part 153 is clamped with the protrusion 141, which makes the second connector 14 cannot be rotated relative to the first connector 13. When the locking part 153 moves away from the locking slot 142, the second connector 14 may be rotated relative to the first connector 13. Furthermore, an allowance slot 1321 is provided on an inner side surface of the second clamping panel 132 facing the button cover 152. The button body 151 slides towards the second clamping panel 132 along the direction perpendicular to the axis of the supporting trunk 11. Subsequently, the locking part 153 moves away from the locking slot 142 and slides into the allowance slot 1321, thereby avoiding a collision between the locking part 153 and the second connector 14 during a rotation of the second connector 14.
In this embodiment, a number of the plurality of locking slots 142 is 3, and the plurality of locking slots 142 are provided at intervals around the rotating shaft of the second connector 14 on a curved edge of one end of the protrusion 141. The plurality of locking slots 142 extend from the bottom of the first connector 13 to the rotating shaft of the second connector 14 along a direction perpendicular to the axis of the rotating shaft of the second connector 14. Therefore, an angle between an extending direction of each of the plurality of locking slots 142 and the axis of the supporting trunk 11 is different when projecting along the axis of rotation shaft of the second connector 14, that is, when the locking part 153 is locked in the locking slot 142 at different positions, an angle of inclination of the trunk is also different.
It should be noted that, since a distance between a bottom surface of the button cover 152 and a sidewall of the second clamping panel 132 of the clamping slot 130 is shorter than the length of the extrusion spring 16 under a normal condition, in the normal condition, the extrusion spring 16 may push the button cover 152 to slide away from the second clamping panel 132, thereby the locking part 153 remains locked in one of the plurality of locking slots 142. At the same time, the first connector 13 and the second connector 14 cannot be rotated. The first connector 13 and the second connector 14 can be rotated only when the button cover 152 is pressed towards the second clamping panel 132 to make the locking part 153 be disengaged from the locking slot 142.
Furthermore, a receiving slot 1302 is provided on an outer wall of the first clamping panel 131. The perforation 1301 is connected to the receiving slot 1302. Wherein, the button cover 152 is disposed in the receiving slot 1302.
In this embodiment, a first through hole 1311 is provided on the first clamping panel 131. A second through hole 1322 corresponding to the first through hole 1311 is provided on the second clamping panel 132. A third through hole 143 is provided on the protrusion 141. Wherein, a fixed bolt 17 is provided through the first through hole 1311, the third through hole 143 and the second through hole 1322, thereby the second connector 14 and the first connector 13 may rotate along the fixed bolt 17.
In an embodiment, the third through hole 143 is provided with an internal thread, and a bottom of the fixed bolt 17 is provided with an external thread connected to the internal thread of the third through hole 143.
A specific working principle is:
In the normal condition, the top trunk 12 is disposed coaxially with the supporting trunk 11. When it is needed to decorate the top of the Christmas tree, the trigger button 15 is pressed to make the locking part 153 of the button body 151 be disengaged from the locking slot 142 of the protrusion 141. At the same time, the second connector 14 may be rotated to drive the top trunk 12 to rotate, so as to adjust the angle of the trunk, which is convenient for people to decorate. When the trigger button 15 is released, the extrusion spring 16 pushes the button cover 152 to move, so that the locking part 153 is locked in the locking slot 142. At this time, the top trunk 12 cannot be rotated, and an angle of the top trunk 12 is fixed.
It should be noted that terms “comprise”, “include” or any other variation are intended to cover non-exclusive inclusions, so that a process, method, article or apparatus that includes a series of elements includes not only those elements, but also other elements not described, or elements inherent in such process, method, article or apparatus. In an absence of further limitations, elements defined by the statement “including a . . . ” do not preclude the existence of other identical elements in the process, method, article or apparatus.
Although embodiments are shown and described, variations, modifications, substitutions and variants of these embodiments may be made by a person skilled in the art without deviating from the principle and spirit of the present application. The scope of the present application is limited by the attached claims and their equivalents.
