[0041] Embodiment 1

[0042] With reference to Figure 1 , Figure 2 A disc hub gear linkage structure 100, comprising a disc head 10, a rod 20 rotatably installed on the disc head 10, a linkage tooth disc 30 and a locking assembly 40 installed in the disc head 10.

[0043] Wherein, the end of the rod 20 is provided with a tooth part 201, the tooth part 201 is engaged with the linkage tooth disc 30, and the locking assembly 40 can be locked at the position of the linkage tooth disc 30 when the rod 20 rotates relative to the disc head 10 and is in an unfolded state.

[0044] The number of the rod 20 is multiple, and when one of the multiple rods 20 rotates on the disc head 10, the tooth part 201 at the end of the rod can touch the linkage tooth disc 30, so that the linkage tooth disc 30 drives the other rods 20 to synchronize linkage.

[0045] Specifically, with reference to Figure 3 , Figure 4 The disc head 10 comprises a disc head upper cover 101 and a disc head lower cover 102 which are spliced with each other, one of the disc head upper cover 101 and the disc head lower cover 102 is provided with a supporting part 103, and the other of the disc head upper cover 101 and the disc head lower cover 102 is provided with a buckling part 104. In the embodiment, the supporting part 103 is installed on the inner side surface of the disc head lower cover 102, and the buckling part 104 is installed on the inner side surface of the disc head upper cover 101. The linkage tooth disc 30 is sleeved outside the supporting part 103. After the disc head upper cover 101 and the disc head lower cover 102 are spliced, the buckling part 104 is buckled with the supporting part 103. The disc head upper cover 101 and the disc head lower cover 102 are fixedly connected through screws, and the locking assembly 40 is installed in the supporting part 103.

[0046] The disc head lower cover 102 is provided with a mounting port 106, and the end of the rod 20 extends into the mounting port 106 and is hinged with the disc head lower cover 102 through a pin shaft 202. The rod 20 can rotate freely relative to the disc head 10 with the pin shaft 202 as a supporting point.

[0047] In addition, the linkage gear disc 30 is sleeved outside the support portion 103, and can move up and down in the disc head 10. In order to prevent the linkage gear disc 30 from rotating circumferentially during movement, a limiting column 107 is connected between the disc head upper cover 101 and the disc head lower cover 102, penetrates the linkage gear disc 30, and has a central axis parallel to the central axis of the support portion 103. The limiting column 107 can limit the circumferential position of the linkage gear disc 30 sleeved on the support portion 103.

[0048] Further, the locking assembly 40 comprises a locking rod 401, an elastic member 402, and a plurality of locking balls 403. One end of the locking rod 401 extends into the support portion 103 and faces the buckling portion 104. An extrusion portion 404 is arranged on the rod body of the locking rod 401 extending into the support portion 103. The outer surface of the extrusion portion 404 is a tapered surface. The elastic member 402 is sleeved on the locking rod 401. One end of the elastic member 402 abuts against the cavity wall of the support portion 103, and the other end abuts against the extrusion portion 404. The locking balls 403 are arranged at the openings 105 on the wall surface of the support portion 103. The number of the openings 105 is plural, and the openings 105 are arranged in a ring shape on the wall surface of the support portion 103.

[0049] The elastic member 402 is preferably a spring. After the locking rod 401 and the elastic member 402 are assembled, the elastic member 402 is in a compressed state in the inner cavity of the support portion 103. Under normal circumstances, the elastic member 402 applies an upward thrust to the extrusion portion 404. Under the thrust of the elastic member 402, the circumferential surface of the extrusion portion 404 can radially extrude the plurality of locking balls 403, so that at least part of the surface of the locking balls 403 is exposed to the outside of the support portion 103 through the openings 105.

[0050] In addition, the locking rod 401 is connected with a cable 405 at an end away from the disc head 10. The cable 405 can drive the locking rod 401 and compress the elastic member 402.

[0051] The rod member 20 on the disc head 10 has a fully unfolded state and a fully folded state during rotation. The principle of the present application is described in detail below in combination with the unfolding process and the folding process of the rod member 20.

[0052] Referring to Figure 4 , Figure 5 , Figure 6, the rod 20 is in the collapsed state, the tooth portion 201 at the end of the rod 20 is in meshing state with the linkage tooth disc 30, at this time, the linkage tooth disc 30 is in the second position in the disc head 10, that is, the linkage tooth disc 30 is close to the inner side of the lower cover 102 of the disc head, at this time, the linkage tooth disc 30 is sleeved outside the plurality of locking balls 403, the locking balls 403 are pressed into the inner cavity of the support portion 103 and cannot be popped out from the opening 105, when the rod 20 is changed from the collapsed state to the expanded state, when any one rod 20 is pried by hand from top to bottom, the tooth portion 201 at the end of the rod 20 drives the linkage tooth disc 30 to move upward outside the support portion 103, in the process of gradually moving upward of the linkage tooth disc 30, the rod 20 is in the gradually expanded state, until the linkage tooth disc 30 moves to the first position in the disc head 10, that is, the linkage tooth disc 30 is close to the inner side of the upper cover 101 of the disc head, at this time, the linkage tooth disc 30 moves to the position above the locking balls 403, at this time, the pressing force of the linkage tooth disc 30 on the locking balls 403 disappears, under the pushing force of the pressing portion 404, the locking balls 403 are popped out from the opening 105, at this time, at least part of the surface of the locking balls 403 is exposed to the outside of the support portion 103 through the opening 105 and limits the linkage tooth disc 30 above, the linkage tooth disc 30 cannot move on the support portion 103, the expanded rod 20 is in the expanded and locked state, therefore, when the rod 20 is in the expanded state, the locking assembly 40 can lock the position of the linkage tooth disc 30, ensuring the stability of the expanded rod 20 and preventing the rod 20 from being accidentally collapsed.

[0053] The process of changing the rod 20 from the expanded state to the collapsed state is as follows: since the rod 20 is in the expanded state, the linkage tooth disc 30 is in the first position, the locking balls 403 limit the linkage tooth disc 30 above, and the rod 20 is in the locked state, therefore, when the rod 20 needs to be collapsed, the locked state thereof needs to be unlocked first, when unlocking, the person pulls the cable 405, under the pulling force of the cable 405, the locking rod 401 compresses the elastic member 402, at this time, the pressing portion 404 descends in the support portion 103, the gap between the pressing portion 404 and the opening 105 becomes larger, when any one rod 20 is rotated by hand, the tooth portion 201 at the end of the rod 20 drives the linkage tooth disc 30 to descend, when the end surface of the linkage tooth disc 30 presses the locking balls 403, the locking balls 403 retract into the inner cavity of the support portion 103 but cannot be popped out from the opening 105, when the rod 20 is continuously rotated, the linkage tooth disc 30 continues to descend, in the descending process, the linkage tooth disc 30 is sleeved outside the plurality of locking balls 403, the locking balls 403 are pressed into the inner cavity of the support portion 103 and cannot be popped out from the opening 105, until the linkage tooth disc 30 moves to the second position, the rod 20 is in the completely collapsed state.

[0054] It should be noted that, since the number of the rod members 20 is multiple, and the toothed portion 201 of the end of each rod member 20 is engaged with the linkage gear disc 30, when any one rod member 20 rotates relative to the disc head 10, the toothed portion 201 of the end of the rod member can touch the linkage gear disc 30 to move longitudinally in the disc head 10, and the longitudinally moving linkage gear disc 30 can drive the other rod members to move synchronously, thus, when the multiple rod members 20 are folded or unfolded, rotating one rod member can ensure that the other rod members rotate synchronously with the rotating rod member, and the consistency and continuity of each rod member 20 in the folding and unfolding process are ensured.

[0057] Finally, it should be noted that: the above embodiments are only used to illustrate the technical solutions of the present application, and not to limit them; although the present application has been described in detail with reference to the foregoing embodiments, those skilled in the art should understand that: it can still modify the technical solutions recorded in the foregoing embodiments, or make equivalent replacement to part or all of the technical features; and these modifications or replacements do not make the essence of the corresponding technical solutions deviate from the scope of the technical solutions of the embodiments of the present application.
