Description

Technical Field

[0001] The utility model relates to the technical field of Christmas trees, in particular to a base of a rotating Christmas tree and a rotating Christmas tree. Background Art

[0002] The Christmas tree is one of the most famous traditional decorations of Christmas. It refers to an evergreen tree decorated with candles and decorations. Today's Christmas trees are usually replaced by industrially produced simulated Christmas trees instead of plant Christmas trees, and are placed statically in the house, which is dull and lacks fun. At present, there are many rotatable Christmas trees on the market, that is, the Christmas tree is driven by a motor to rotate slowly in the axial direction, thereby improving the ornamental value of the Christmas tree. However, the control of this rotation usually has a single mode and is relatively dull, which can no longer meet the needs of people today. In addition, the existing Christmas tree lights usually require an additional control module to realize the flashing of the lights. However, the control module is large in size, which affects the appearance of the Christmas tree and increases the production cost of the Christmas tree. Utility Model Content

The plug-in slot facilitates circuit connection and disassembly, and the elastic member ensures the fit between the carbon brush and the conductive column, thereby improving the power-on stability.

[0013] Furthermore, the base further comprises a limiting sleeve, which is sleeved in the socket and used to insert the Christmas tree and limit its radial movement. The limiting sleeve is convenient for limiting the position of the Christmas tree and improving the stability of the Christmas tree during rotation.

DETAILED DESCRIPTION

[0025] See also Figure 1-3 , Figure 1 is a structural cross-sectional view of the rotating Christmas tree; Figure 2 is a structural schematic diagram of the carbon brush; Figure 3 It is a schematic diagram of the structure of the fixing plate in Example 1. A rotating Christmas tree comprises a main rod 1 and a base 2, wherein the main rod 1 is inserted into the base 2.

[0026] The main rod 1 comprises a first rod body 11 and a second rod body 12 connected axially to each other, a wire splitter 13 is provided at the bottom of the first rod body 11, and a power interface is also provided on the main rod 1.

The connection structure of the power interface and decorative electrical components such as light strips can refer to the patent with publication number CN210582082U and the name of "A Christmas Tree".

[0027] The base 2 includes a bracket 21, a rotating conductive module 22, a limiting sleeve 23, a first bearing 24 and a ball 25. The bracket 21 has a socket at the top and a mounting cavity in the middle that is connected to the socket. The second rod 12 is inserted into the rotating seat 221 and rotates with the rotating seat 221.

[0028] The rotating conductive module 22 is arranged in the installation cavity, and includes a rotating seat 221, a motor 222 and a carbon brush 223. The rotating seat 221 is rotatably arranged in the bracket 21 to drive the Christmas tree to rotate. The motor 222 drives the rotating seat 221 to rotate axially. A fixed plate 226 made of insulating material is arranged in the middle of the rotating seat 221, and a first conductive column 227 and a second conductive column 228 are inserted in the fixed plate 226. When the rotating seat 221 rotates, there are two carbon brushes 223 and they intermittently rub against the first conductive column 227 and the second conductive column 228 respectively, or there are two carbon brushes 223, one of which keeps in contact with the first conductive column 227, and the other intermittently rubs against the second conductive column 228. The bottoms of the first conductive column 227 and the second conductive column 228 are flush with the bottom of the fixed plate 226. The number of the second negative electrode wires 16 is greater than the number of the second conductive posts 228 . The second negative electrode wires 16 are inserted into the second conductive posts 228 according to customer requirements to form one or more connection combinations of the second conductive posts 228 .

[0029] Preferably, the inner side of the rotating seat 221 is provided with a convex strip, the convex strip extends axially to cooperate with the main stem 1 of the Christmas tree, the outer side is provided with meshing teeth, and the output end of the motor 222 is provided with a driving gear, and the driving gear meshes with the meshing teeth. The second rod body 12 is provided with a groove corresponding to the convex strip.

[0030] In this embodiment, the fixed plate 226 is divided into annular first friction zone 2261 and second friction zone 2262, the first friction zone 2261 and the second friction zone 2262 are concentric with the rotation axis, the first conductive column 227 is penetrated in the first friction zone 2261, the second conductive column 228 is penetrated in the second friction zone 2262, and the first conductive column 227 and the second conductive column 228 are located on the same radius.

[0031] The first conductive column 227 and the second conductive column 228 are both provided with a plug-in slot 229, and the plug-in slot 229 is used to be detachably connected to the positive wire 14 and the second negative wire 16 of the Christmas tree. The carbon brush 223 includes a carbon block 2231 and an elastic member 2232 arranged at the bottom of the carbon block 2231. The elastic member 2232 presses the carbon block 2231 toward the fixing plate 226, so that the carbon block 2231 is in contact with and fits the first conductive column 227 or the second conductive column 228, and the carbon block 2231 is electrically connected to the power supply through a wire.

[0032] The limiting sleeve 23 is sleeved in the socket, and is used to insert the Christmas tree and limit its radial movement. A mounting groove is provided on the inner side of the limiting sleeve 23, and the ball 25 is arranged in the mounting groove. The first bearing 24 is a thrust ball bearing and is arranged in the mounting cavity, and its bottom side contacts the bracket 21, and its top side is used to support the Christmas tree.

[0033] Before use, the user hangs the colored lights on the Christmas tree and connects its power cord to the power interface on the Christmas tree. The power interface is then connected to the first conductive column and the second conductive column through wires, and then the Christmas tree is inserted into the bracket and fixed through the limit sleeve. When in use, the motor drives the rotating seat to rotate. At this time, the carbon brush is connected to the external power supply. When the first conductive column and the second conductive column are in friction contact with the carbon brush, a current loop is formed, and the external power supply can supply power to the colored lights, and the colored lights light up. When the first conductive column or the second conductive column is not in friction contact with the carbon brush, a current loop cannot be formed and the colored lights go out. As the rotating seat rotates, the carbon brush regularly contacts the first conductive column and the second conductive column, thereby forming a regular on and off of the circuit, and the flashing of the colored lights can be realized. When the rotation speed of the rotating seat is increased, the flashing frequency of the colored lights can be increased.

[0034] Example 2

[0035] See also Figure 4 , Figure 4 Schematic diagram of the structure of the fixed plate in Example 2. This embodiment is basically the same as Example 1, and the only difference is that the first conductive column 227 is concentric with the rotation axis, and the fixed plate 226 is penetrated by a second conductive column 228 deviating from the rotation axis. When in use, the first conductive column keeps in contact with the carbon brush, that is, keeps in a connected state, and the second conductive column regularly contacts with another carbon brush, thereby forming a regular on-off of the circuit, and the flashing of the colored lights can be realized. When the rotation speed of the rotating seat is increased, the flashing frequency of the colored lights can be increased.

[0036] Example 3

[0037] See also Figure 5 , Figure 5 Schematic diagram of the structure of the fixing plate in Example 3. This embodiment is basically the same as Example 1, with the only difference that: there are multiple second conductive pillars 228 and they are spaced outside the first conductive pillar 227 along the circumferential direction, the center of the circle in the circumferential direction coincides with the rotation axis, the spacing between adjacent second conductive pillars 228 is equal or unequal, and the spacing between adjacent second conductive pillars 228 is greater than or less than the diameter of the carbon brush.

[0038] When in use, customers can customize the connection of one or more second negative wires to the second conductive posts to form a variety of connection combinations. For example, by connecting one second negative wire to one second conductive post, and then connecting the other three second negative wires to the three second conductive posts on the other side, the effect of the colored lights flashing alternately once and three times can be achieved.

[0039] When the distance between the second conductive pillars is smaller than the size of the carbon block, that is, when the carbon brush switches between adjacent and connected second conductive pillars, no circuit breakage will occur. The above connection method can achieve the effect of alternating short-term and long-term lighting of the colored lights.

[0040] The utility model discloses a rotating Christmas tree base and a rotating Christmas tree, which can realize intermittent on and off of the Christmas tree circuit through intermittent friction between the carbon brush and the first conductive column and the second conductive column, thereby controlling the connected light bar to flash, without using an additional control module, thereby reducing production costs. At the same time, the flashing frequency of the light bar can be adjusted by controlling the rotation speed of the Christmas tree, thereby realizing the interaction between the user and the rotation of the Christmas tree, and improving the use pleasure of the Christmas tree.

[0041] The above-mentioned embodiments only express several implementation methods of the utility model, and the description is relatively specific and detailed, but it cannot be understood as limiting the scope of the utility model patent. It should be pointed out that for ordinary technicians in this field, several modifications and improvements can be made without departing from the concept of the utility model, and the utility model is also intended to include these modifications and modifications.
