DETAILED DESCRIPTION

[0023] The utility model discloses a christmas tree mounting seat, the traditional structure has carried out the improvement, makes the whole volume reduces, and the structure is more simple and compact. The christmas tree mounting seat includes the base 1 and the support seat 2 of being connected, and the base 1 and the support seat 2 surround and form a containing cavity, and the base 1 and the support seat 2 are provided with the first flange 11 and the second flange 21 extending to the containing cavity respectively. The containing cavity still is provided with the first plug-in seat 3 and the second plug-in seat 4 of mutually clamping along the axial direction, and the first plug-in seat 3 and the second plug-in seat 4 are rotatably clamped between the first flange 11 and the second flange 21, and can rotate along the circumference relative to the base 1 and the support seat 2. The first plug-in seat 3 and the second plug-in seat 4 are internally provided with a cavity, and the end of the second plug-in seat 4 passes out the support seat 2, and the end is provided with the plug-in hole 41 of communicating with the cavity.

[0024] When using, the bottom end of the christmas tree trunk can be inserted into the plug-in hole 41 and extend into the cavity. The containing cavity is also provided with a drive source, the drive source drives the first plug-in seat 3 to rotate, the first plug-in seat 3 drives the second plug-in seat 4 to rotate, and then drives the inserted christmas tree to rotate.

[0025] In order to improve the smoothness of rotation, reduce the wear between structures and the noise generated during rotation, the containing cavity is also provided with a plurality of first rolling bodies 6 and second rolling bodies 7, which can have various structural forms. In this embodiment, they are spherical. The first rolling body 6 is rotatably arranged between the first flange 11 and the first plug-in seat 3, and the second rolling body 7 is rotatably arranged between the second plug-in seat 4 and the second flange 21.

[0026] The clamping mode of the first plug-in seat 3 and the second plug-in seat 4 can have various structural forms. In this embodiment, the first plug-in seat 3 is provided with a plurality of clamping bosses 31 along the circumference, and the second plug-in seat 4 is provided with a plurality of clamping grooves 42 corresponding to the clamping bosses 31 along the circumference. In order to prevent the first plug-in seat 3 and the second plug-in seat 4 from being separated during rotation, the first plug-in seat 3 or the second plug-in seat 4 is also provided with a plurality of limiting protrusions 9 along the circumference. The limiting protrusions 9 extend along the axial direction and can strengthen the structural strength of the first plug-in seat 3. The limiting protrusions 9 protrude from the first plug-in seat 3 or the second plug-in seat 4 and abut against the outer wall of the second plug-in seat 4 or the first plug-in seat 3, thereby limiting the relative position of the first plug-in seat 3 and the second plug-in seat 4.

[0027] The drive source drives the first plug-in seat 3 in various ways. The first plug-in seat 3 is provided with a meshing tooth 32 along the circumference, and the drive source includes a motor 51 and a main gear 52 driven by the motor 51. The main gear 52 is engaged with the meshing tooth 32. When the motor 51 is started, the motor 51 drives the main gear 52 to rotate, and the main gear 52 drives the first plug-in seat 3 to rotate through engagement, and then drives the christmas tree to rotate through the second plug-in seat 4.

[0028] The inner wall of the first support base 2 is provided with a plurality of reinforcing ribs 33 extending in the axial direction, which are distributed in the circumferential direction to improve the structural strength of the first support base 2 and prevent deformation.

[0029] The trunk of the Christmas tree is matched with the insertion hole 41 through the insertion piece 8, and the inner wall of the insertion piece 8 is provided with a plurality of first abutting protrusions 81 in the circumferential direction to abut against the Christmas tree, thereby being fixed with the trunk. In order to ensure that the trunk can be accurately and quickly inserted into the insertion piece 8, the top end of the first abutting protrusion 81 is provided with an inclined first guide surface, and the bottom of the trunk can slide into the insertion piece 8 along the first guide surface during the insertion process. The outer wall of the insertion piece 8 is provided with a plurality of second abutting protrusions 82 in the circumferential direction to fit with the insertion hole 41 in an interference fit, so that the first insertion seat 3 can drive the insertion piece 8 to rotate. Similarly, in order to facilitate the insertion of the insertion piece 8 into the insertion hole 41, the bottom end of the second abutting protrusion 82 is provided with an inclined second guide surface.

[0030] The base 1 is uniformly and spacedly provided with a plurality of insertion slots 12 in the circumferential direction, which are used for insertion and cooperation with the support legs 10 extending radially outward and abutting against the ground, thereby improving the stability of the mounting seat. The structure of the insertion leg 10 can have various structural forms, which are prior art in the field and will not be described here.

[0031] A large number of decorations are usually needed to be hung on the Christmas tree to improve the overall aesthetic appearance, and the most common decoration is a string of lights. In order to ensure that the electric wire of the string of lights wound during the rotation of the Christmas tree will not be tightened and broken, the running direction of the electric wire needs to be reasonably arranged. The wire 11 has a first end 111 and a second end 112 at both ends. The first end 111 is provided with a string of light power connector or a string of light power socket for electrical connection with the string of lights through insertion. The second end 112 is inserted into the cavity through the through hole of the second insertion seat 4, passes through the bottom of the first insertion seat 3 and is then inserted out of the base 1, and the second end 112 is provided with a power plug for electrical connection with an external power source. A controller can also be connected in series on the wire 11 to control the light effect of the string of lights.

[0032] When the first insertion seat 3 and the second insertion seat 4 rotate, the wire 11 moves with the second insertion seat 4 in a small range and can rotate in the through hole, thereby ensuring the conductivity of the wire 11 while giving the wire 11 a certain degree of freedom, avoiding the problem that the electric wire wound on the outside of the base 1 in the traditional way will be further wound on the base 1 during rotation, causing the electric wire to be pulled tighter and tighter.

[0033] The control switch of the conventional artificial Christmas tree is usually located on the mounting base. However, since the mounting base is usually located at the bottom of the central axis of the Christmas tree, when the branches are spread, the outer diameter of the bottom of the Christmas tree increases, and the volume of the mounting base is small, so the user needs to climb into the bottom of the Christmas tree to press the control switch. This increases the difficulty of the user to operate the control switch, and the rotating Christmas tree is easy to cause injury to the user, and the safety is low.

[0034] As another embodiment, a control circuit board is further included, and the control circuit board is electrically connected with the driving source. The length of the clamping protrusion 31 in the circumferential direction is less than the length of the clamping groove 42 in the circumferential direction, so that the first plug-in seat 3 and the second plug-in seat 4 have a certain relative rotation in the circumferential direction. The first conductive block 34 is arranged on the end face located on the front side in the rotation direction of the clamping protrusion 31, and the clamping groove 42 is provided with the second conductive block 43 corresponding to the first conductive block 34, and the first conductive block 34 and the second conductive block 43 are respectively electrically connected with the positive electrode and the negative electrode of the control circuit board and are connected in series with the driving source.

[0035] Taking the clockwise rotation of the first plug-in seat 3 to drive the Christmas tree as an example, when the power is turned on, the first conductive block 34 and the second conductive block 43 are still in a state of mutual separation, and at this time the driving source is de-energized and not started. At this time, by means of the structure such as the branches, the trunk of the Christmas tree is counterclockwise rotated, the trunk drives the second plug-in seat 4 to rotate counterclockwise, and the second conductive block 43 approaches the first conductive block 34 until it is attached. At this time, the circuit is connected, the driving source is energized and started, the first plug-in seat 3 is rotated clockwise by the main gear 52, the first plug-in seat 3 drives the second plug-in seat 4, and the trunk is also rotated clockwise. In this process, the first conductive block 34 and the second conductive block 43 remain in abutment, thereby ensuring the stability of the circuit connection.

[0036] In order to facilitate the closing of the rotation function of the Christmas tree, the first magnetic attraction block 35 is arranged on the end face located on the rear side in the rotation direction of the clamping protrusion 31, and the clamping groove 42 is provided with the second magnetic attraction block 44 corresponding to the first magnetic attraction block 35. Still taking the clockwise rotation of the first plug-in seat 3 to drive the Christmas tree as an example, when it is necessary to pause the rotation of the Christmas tree, by means of the structure such as the branches, the trunk of the Christmas tree is accelerated to rotate clockwise, the trunk drives the second plug-in seat 4 to accelerate to rotate clockwise, the second conductive block 43 is separated from and away from the first conductive block 34 until the first magnetic attraction block 35 and the second magnetic attraction block 44 are attracted, the circuit is disconnected, the driving source is closed, and the first conductive block 34 and the second conductive block 43 remain separated, as shown in FIG. 6, so as to avoid the driving source from being started due to accidental touch. Figure 4

[0037] The Christmas tree mounting base provided by the utility model has the advantages that the structure of the mounting base is reasonably designed, the whole mounting base structure is simple and compact, the volume of the mounting base is greatly reduced, and the appearance of the Christmas tree is improved.​
