[0038] With reference Figures 1 to 11 The embodiment provides a kind of foldable support, including adjustment assembly 1, first support 21 and second support 22, the adjustment assembly 1 includes base 11, control sleeve 12, limit sleeve 13 and locking assembly 14, the limit sleeve 13 is located between the base 11 and the control sleeve 12, the limit sleeve 13 is connected to the base 11, first through-hole 131 is provided on the limit sleeve 13, second through-hole 111 is provided on the base 11, the second through-hole 111 is located below one end of the first through-hole 131, the locking assembly 14 includes limit column 141 and elastic piece 142, the control sleeve 12 is located at one end of the elastic piece 142, the limit column 141 is located at the other end of the elastic piece 142, the limit column 141 is located in the first through-hole 131, the first support 21 is connected to the base 11, and the second support 22 is connected to the control sleeve 12.

[0039] Under the action of external force, the limit column 141 and the control sleeve 12 can slide along the first through-hole 131, and the base 11 and the limit sleeve 13 are relatively moved, so that the first support 21 and the second support 22 are relatively moved, to realize the foldable function of support.

[0040] For the convenience of description, the two ends of the first through hole 131 are respectively set as A end and B end, and it is assumed that the second through hole 111 is arranged below the A end of the first through hole 131. In the initial state, the bottom of the limiting column 141 is inserted into the second through hole 111, the second through hole 111 can limit the control sleeve 12 and the limiting column 141, and the limiting column 141 cannot move towards the direction of the B end, so that the control sleeve 12 and the base 11 are in a relatively fixed state.

[0041] In the assembly, it is set that the control sleeve 12 and the base 13 are in a relatively fixed state, and the support is completely opened; it is set that the control sleeve 12 and the base 13 are in a relatively movable state, and the angle of the support can be adjusted or folded.

[0042] When it is necessary to adjust the relative position of the control sleeve 12 and the base 11, an external force is applied to make the limiting column 141 move upwards and compress the elastic member 142, the bottom of the limiting column 141 is separated from the second through hole 111, and the limiting column 141 can continue to move towards the direction of the B end. The limiting column 141 drives the control sleeve 12 to move, and the elastic restoring force of the elastic member 142 makes the lower end of the limiting column 141 abut against the upper surface of the base 11. When the limiting column 141 moves to the A end again, the restoring force pushes the limiting column 141 to be inserted into the second through hole 111 again.

[0043] Further, the control sleeve 12, the base 11 and the limiting sleeve 13 are all arranged in a ring structure.

[0044] Further, the first through hole 131 is arranged as an arc-shaped hole, and the second through hole 111 is arranged as a circular hole.

[0045] Preferably, the control sleeve 12 is provided with a mounting groove 121, and one end of the elastic member 142 is arranged in the mounting groove 121.

[0046] In the embodiment, the elastic member 142 is a spring, and in actual application, other components with elastic compression and restoring functions can be selected to replace the spring.

[0047] Preferably, the locking assembly 14 comprises a connecting block 143, the limiting column 141 is connected to the bottom of the connecting block 143, and the side of the connecting block 143 is provided with a protruding button 146. The user can drive the connecting block 143 to move through the button 146, and then drive the limiting column 141 to move, so that the user can conveniently adjust the control sleeve 12.

[0048] Preferably, the top of the connecting block 143 is provided with a groove 144, and the end of the elastic member 142 is arranged in the groove 144. The groove 144 can prevent the spring from being deviated or rotated under force, so that the spring can move along a specific path or direction during operation, ensuring the stability of the spring.

[0049] Further, the bottom of the connecting block 143 is provided with a limiting block 145, and the outer edge of the limiting sleeve 13 is provided with a limiting groove 132 corresponding to one end of the first through hole 131.

[0050] Specifically, the limiting groove 132 corresponds to the A end of the first through hole 131, and when the limiting column 141 is inserted into the second through hole 111, the limiting block 145 is synchronously inserted into the limiting groove 132, achieving the effect of secondary positioning, so that the control sleeve 12 and the base 11 are in a relatively fixed state. When it is necessary to adjust the relative position of the control sleeve 12 and the base 11, an external force is needed to move the button, so that the connecting block 143 moves upward, driving the limiting block 145 to be separated from the limiting groove 132, and the limiting column 141 is separated from the second through hole 111, so that the control sleeve 12 and the base 11 can be relatively rotated.

[0051] By connecting the first support 21 and the second support 22 of the support to the control sleeve 12 and the base 11 respectively, the first support 21 and the second support 22 can be folded or unfolded with each other, and when not in use, the support can be folded for convenient storage, and when in use, the support can be unfolded to provide support.

[0052] For convenience of description, it is assumed that the Christmas tree support in the embodiment is in a folded state, the limiting column 141 is located at the B end of the first through hole 131, and the first support 21 and the second support 22 are arranged adjacent to each other, occupying a small space, and being convenient for the user to store; when the support in the embodiment is needed to be used, an external force is applied to make the limiting column 141 slide towards the A end of the first through hole 131, the control sleeve 12 and the base 11 are relatively rotated, driving the first support 21 and the second support 22 to also synchronously rotate, until the limiting column 141 is inserted into the second through hole 111, and the support is in a fully unfolded state, which is convenient for the user to place the support on the ground, and insert the Christmas tree ornament in the control sleeve 12, achieving the support of the Christmas tree.

[0054] Further, the end of the connecting column 23 is provided with a first thread 231, and the inner wall of the control sleeve 12 is provided with a second thread 122, and the connecting column 23 and the control sleeve 12 are connected through thread cooperation.

[0055] It can be understood that the service life of the elastic member 142 is limited, and after frequent use, the elastic member 142 will lose elasticity and cannot provide an effective pushing force for the movement of the limiting column 141, so that the limiting column 141 cannot be inserted into the second through hole 111, and the control sleeve 12 cannot be kept in a relatively fixed state with the base 11. By designing the connecting structure of the connecting column 23 and the control sleeve 12 as a detachable threaded connection, the user can threadedly unscrew and remove the control sleeve 12 to replace the elastic member 142, so as to ensure that the adjusting assembly 1 can work normally.

[0056] It should be particularly pointed out that the part of the connecting column 23 inserted into the insertion slot 2111 is in interference fit with the insertion slot 2111, so that the connecting column 23 and the central shaft 211 are in a fixed state, which can prevent relative rotation between the two. Correspondingly, when there is a force to rotate the connecting column 23, the connecting column 23 will drive the central shaft 211 to rotate together.

[0057] In the process of opening and folding the support, the first support 21 rotates relative to the second support 22, and the control sleeve 12 and the limiting column 141 also rotate synchronously, until the limiting column 141 moves to the A end of the first through hole 131 and is inserted into the second through hole 111 or the limiting column 141 moves to the B end of the first through hole 131, the first support 21 will not be able to rotate relative to the second support 22.

[0058] According to the above, it can be known that the first through hole 131 is an arc-shaped through hole, and the extension angle of the arc-shaped through hole is the angle that the first support 21 can rotate. Specifically, the angle of the first through hole 131 is 90 degrees in this embodiment, and correspondingly, the angle that the first support 21 can rotate relative to the second support 22 is also 90 degrees. The first support 21 is provided with two opposite supporting legs, and the second support 22 is provided with two opposite supporting legs. When the first support 21 and the second support 22 are completely opened, the supporting legs of the first support 21 and the supporting legs of the second support 22 are perpendicular to each other, and together provide stable supporting force.

[0059] Preferably, the center shaft 211 comprises a center part 2112 and a connecting part 2113, the second support 22 comprises a first connecting ring 221 and a second connecting ring 222, the first connecting ring 221 is arranged apart from the second connecting ring 222, the second connecting ring 222 is sleeved on the outer periphery of the connecting part 2113, the first connecting ring 221, the base 11 and the limiting sleeve 13 are all sleeved on the outer periphery of the connecting column 23, and the base 11 and the limiting sleeve 13 are located above the first connecting ring 221 and fixedly connected with the first connecting ring 221.

[0060] Preferably, the outer diameter of the connecting part 2113 is adapted to the inner diameter of the second connecting ring 222, and the outer diameter of the second connecting ring 222 is adapted to the outer diameter of the center part 2112. When the first support 21 and the second support 22 are assembled together, the whole is more beautiful.

[0061] The assembling steps of the support of the embodiment are as follows:

[0062] First, the second connecting ring 222 of the second support 22 is sleeved on the outer periphery of the connecting part 2113, the first connecting ring 221 of the second support 22 is located at the top of the center shaft 211 and coincides with the axis of the center shaft 211, and the connecting column 23 is inserted into the insertion slot 2111 on the first support 21 after penetrating through the first connecting ring 221 and tightly fits with the first support 21; second, the control sleeve 12 and the connecting column 23 are connected through threads; and finally, the base 11 and the first connecting ring 221 are fixedly connected, thus the support is assembled.
