[0042] The technical solutions in the embodiments of the present application will be described clearly and completely below with reference to the drawings in the embodiments of the present application. Obviously, the described embodiments are only some of the embodiments of the present application, but not all the embodiments of the present application. Based on the embodiments in the present application, all the other embodiments obtained by those skilled in the art without creative work fall within the scope of protection of the present application.

[0043] It should be noted that when a component is referred to as being “connected” with another component, it can be directly connected with the other component or there can be a middle component. When a component is referred to as being “disposed on” another component, it can be directly disposed on the other component or there can be a middle component.

[0044] Unless otherwise defined, all technical and scientific terms used herein have the same meaning as commonly understood by one of ordinary skill in the art to which this application belongs. The terminology used in the description of the application herein is for the purpose of describing particular embodiments only and is not intended to be limiting of the application. As used herein, the term “and / or” includes any and all combinations of one or more of the associated listed items.

[0045] In the present application, the terms “first”, “second”, etc. are only used for the purpose of description, and cannot be understood as indicating or implying relative importance or implicitly indicating the number or order of the indicated technical features. Therefore, the features defined with “first”, “second” can explicitly or implicitly include one or more of the features. In the description of the present application, the meaning of “plurality” is at least two, for example, two, three, etc., unless otherwise specifically limited.

[0046] Reference is made to Figures 1-7The application provides a rotation angle adjusting device for adjusting the included angle of two relatively rotatable components. The device comprises a first connecting member 100 and a second connecting member 200 connected by a rotating shaft and relatively rotatable about a first rotating axis 11, the first connecting member is provided with a positioning member 300 movable relative to the second connecting member 200, the second connecting member 200 is provided with a plurality of coupling portions 220 arranged about the first rotating axis 11, the positioning member 300 has a first position for limiting the relative rotation of the first connecting member 100 and the second connecting member 200 by engaging one of the coupling portions 220, and a second position for allowing the relative rotation of the first connecting member 100 and the second connecting member 200 by disengaging the current coupling portion 220.

[0047] The elastic member 400 directly or indirectly acts on the positioning member 300 to make it approach the second connecting member 200, and to make the positioning member 300 and the coupling portion 220 keep in engagement. If a rotating force greater than a certain value is applied to the second connecting member 200, the positioning member 300 can be driven to disengage the current coupling portion 220, and the elastic member 400 can be compressed, and the relative rotation of the two connecting members can occur. When the second connecting member 200 rotates by a certain angle relative to the first connecting member 100, the positioning member 300 passes the current coupling portion 220 and corresponds to the next coupling portion 220, the elastic member 400 resets to drive the positioning member 300 to engage the coupling portion 220 again to limit the relative rotation of the two connecting members, and the relative position of the two connecting members can be adjusted.

[0048] In order to keep the relative position of the two connecting members, i.e. the positioning member 300 always engages the current coupling portion, the rotation angle adjusting device further comprises a locking member 500 having a locking position and a releasing position. In the locking position, the locking member 500 locks the positioning member 300, the positioning member 300 cannot move, always engages the coupling portion, and the two connecting members cannot rotate, i.e. the angle cannot be adjusted. In the releasing position, the locking member 500 releases the positioning member 300, the positioning member 300 can move again, and the angle can be adjusted by external force.

[0049] The positioning member 300 is movable along a first direction, the locking member 500 is rotatable about a second rotation axis 12 parallel to the first direction, and the locking member 500 is provided with a first inclined surface 510 arranged about the second rotation axis 12, the first inclined surface 510 having a higher locking position and a lower release position, the locking position and the release position having a height difference along the first direction. When the locking member 500 is rotated to the locking position, the locking position of the first inclined surface 510 abuts against the positioning member 300 to prevent the positioning member 300 from moving. When the locking member 500 is rotated to the release position, the release position avoids the positioning member 300 to allow the positioning member 300 to disengage from the coupling portion 220. Compared with the existing threaded connection, the locking member 500 can be quickly switched between the locking position and the release position, and the corresponding locking operation and release operation are faster, such as significantly reducing the number of rotations of the locking member 500. The first inclined surface 510 has a highest position 513 along the first direction, and the locking position is lower than or equal to the highest position along the first direction.

[0050] In an embodiment, the first inclined surface 510 has a central angle corresponding to the release position and the locking position less than 360 degrees, that is, the number of rotations of the locking member 500 from the release position to the locking position is less than one rotation. Further, the first inclined surface 510 is two groups and is symmetrically arranged about the second rotation axis 12, and each group of the first inclined surface 510 has a central angle corresponding to the release position and the locking position less than 180 degrees, which improves the stability of the locking and the movement stability of the locking member 500 and the positioning member 300.

[0051] For convenience of operation, in an embodiment, the surface of the locking member 500 is provided with anti-skid lines or protruding operation portions 520.

[0052] Two different embodiments are provided below:

[0055] The elastic member 400 is, for example, a cylindrical spring, and is arranged between the positioning member 300 and the first connecting member 100. Specifically, as shown in Figures 3-5The first connecting piece 100 is provided with a mounting groove 130 at one end of the connecting arm 120, and the elastic member 400 is at least partially mounted in the mounting groove 130. The positioning member 300 is provided with a convex column 320 at one end for clamping the elastic member 400 and is provided with a tooth structure at the other end for engaging the coupling part 220. The convex column 320 is partially arranged in the mounting groove 130 to avoid being pulled out of the first connecting piece 100. In the preferred embodiment, the positioning member 300 is provided with a plurality of first engaging teeth arranged around the second rotation axis 12, and the coupling part 220 is provided with a plurality of second engaging teeth arranged around the second rotation axis 12. When the positioning member 300 is in the first position, the two engaging teeth are engaged with each other. When the positioning member 300 is in the second position, the two engaging teeth are separated from each other.

[0056] As shown in Figure 6 and Figure 7 In one embodiment, the rotation angle adjusting device comprises a transmission member 600 arranged between the locking member 500 and the positioning member 300. In the illustration, the transmission member 600 is arranged in the first connecting piece 100 in the first direction. The locking member 500 is a cylindrical structure and is sleeved on the outer periphery of the first connecting piece 100. The locking member 500 is provided with a first end face and a second end face in the first direction. The first connecting piece 100 is provided with a blocking part 140 protruding radially outward to prevent the locking member 500 from slipping off, and the blocking part 140 is located on the side of the first end face. A first inclined surface 510 is arranged on the second end face. The low position 512 (unlocking position) of the first inclined surface 510 is connected to the second end face, and the locking position of the first inclined surface 510 is protruding relative to the second end face and is lower than the highest position 511.

[0057] As shown in Figure 3 , the transmission member 600 is a cylindrical structure and is sleeved on the outer periphery of the first connecting piece 100. The first connecting piece 100 is provided with a limiting part 150 for limiting the rotation of the transmission member 600, and the limiting part 150 is a flat surface arranged on the outer periphery of the first connecting piece 100. The transmission member 600 is provided with a second inclined surface 610 matched with the first inclined surface 510. The second inclined surface 610 has a highest position 611, a low position 612 and a high position 613 extending in the first direction. The high position 613 is lower than the highest position 611.

[0058] As shown in Figure 1 , Figure 6 and Figure 7 When the locking member 500 is in the unlocking position, the low position 512 (unlocking position) of the first inclined surface 510 corresponds to the highest position 611 of the second inclined surface 610, and the highest position 511 of the first inclined surface 510 corresponds to the low position 612 of the second inclined surface 610. Figure 1In the middle, due to the action of gravity, the transmission member 600 and the locking member 500 are close to the blocking part 140 and away from the avoiding positioning member 300, that is, the transmission member 600 and the positioning member 300 are arranged at intervals, and the positioning member 300 is switched to the second position by sliding under the action of the sufficient rotating force applied to the two connecting members respectively; after being adjusted to the required position, the locking member 500 is rotated until, as shown in Figure 2 , the locking member 500 is switched to the locking position, the locking member 500 and the transmission member 600 are away from each other, and the high position 513 (locking position) of the first inclined surface 510 and the high position 613 of the second inclined surface 610 correspond and abut, one end of the transmission member 600 abuts against the positioning member 300, and one end of the locking member 500 abuts against the blocking part 140, thereby limiting the sliding of the positioning member 300, that is, keeping the positioning member 300 in the first position.

[0059] Embodiment two:

[0060] As shown in Figures 8-10 , the first rotating axis 11 and the second rotating axis 12 coincide, the second connecting member 200 has a connecting shaft 230 passing through the positioning member 300 and the first connecting member 100, and the connecting shaft 230 is arranged in the direction of the second rotating axis 12. The locking member 500 is sleeved on the connecting shaft 230, and the connecting shaft 230 is provided with a limiting part 240 limiting the locking member 500 from being detached, specifically, one end of the connecting shaft 230 is threadedly connected with a screw, the screw is provided with a gasket as the limiting part 240, the locking member 500 is between the first connecting member 100 and the limiting part 240, and the elastic member 400 is a spring and acts on the limiting part 240 and the locking member 500 at two ends respectively, and the acting force of the spring is conducted to the first connecting member 100 by the locking member 500.

[0061] As shown in Figure 11 and Figure 12 , the positioning member 300 and the first connecting member 100 are fixedly connected, the positioning member 300 and the coupling part 220 are in a tooth structure, the positioning member 300 is a plurality of first meshing teeth arranged at intervals around the second rotating axis 12, and the second connecting member 200 is provided with second meshing teeth matched with the first meshing teeth.

[0062] The first connecting member 100 is provided with a first connecting part 110, which is a socket for inserting and fixing a rod member, and the second connecting member 200 is provided with a second connecting part 210, which is a through hole for passing and fixing a rod member. The locking member 500 is in a cylindrical structure and is provided with an operating part 520 protruding. The locking member 500 has a first end face and a second end face in the axial direction, the second end face is provided with a first inclined surface 510, and the first connecting member 100 is provided with a third inclined surface 160 matched with the first inclined surface 510 at one end close to the locking member 500 in the axial direction.

[0063] Again in combination with 14- Figure 16, the low position 512 (the release position) of the first inclined surface 510 is connected to the second end surface, and the high position 513 (the locking position) is protruded relative to the second end surface and is lower than the highest position 511. The adjustment angle operation is as follows: when the locking member 500 is in the release position, the low position 512 (the release position) of the first inclined surface 510 corresponds to the highest position 161 of the third inclined surface 160, and the highest position 511 of the first inclined surface 510 corresponds to the low position 162 of the third inclined surface 160. Under the action of the elastic member 400, the locking member 500 and the first connecting member 100 are in close contact, and the locking member 500 and the limiting portion 240 are spaced apart. When an external force is applied to the two connecting members, the positioning member 300 is separated and drives the first connecting member 100 to slide axially, and simultaneously drives the locking member 500 to slide axially and close to the limiting portion 240, until the required angle is adjusted, and the external force is released. The elastic member 400 is reset and acts on the locking member 500 and the first connecting member 100, so that the positioning member 300 moves again and switches to the first position.

[0064] Then, the locking operation is performed: the locking member 500 is rotated to the locking position, at this time, the high position 513 (the locking position) of the first inclined surface 510 corresponds to and abuts against the high position 163 of the third inclined surface 160, and the locking member 500 generates axial sliding. Finally, the two ends of the locking member 500 in the axial direction abut against the first connecting member 100 and the limiting portion 240 respectively, thereby keeping the positioning member 300 in the first position.

[0065] Referring back to Figure 11 and Figure 12 , in an embodiment, the first inclined surface 510 has a first abutting surface 515 on one side of the highest position 511, and the third inclined surface 160 has a second abutting surface 165 on one side of the highest position 161. When the locking member 500 is rotated in the first circumferential direction, the locking member 500 is switched from the release position to the locking position; when the locking member 500 is rotated in the second circumferential direction, the locking member 500 is switched from the locking position to the release position. The locking member 500 also has a driving position as shown in Figure 8 , in which the first abutting surface 515 abuts against the second abutting surface 165, and the locking member 500 is rotated in the second circumferential direction and drives the first connecting member 100 to rotate relative to the second connecting member 200. In an embodiment, the driving position and the release position are the same.

[0066] As shown in Figure 17As shown, the present application provides an umbrella, such as a sun umbrella, a fishing umbrella, etc. The umbrella comprises a canopy, a first umbrella rod, a second umbrella rod and a rotation angle adjusting device. The rotation angle adjusting device can refer to the foregoing embodiments. The first connecting member 100 is used to connect the first umbrella rod 410, and the second connecting member 200 is used to connect the second umbrella rod 420. The first umbrella rod 410 is inserted into the ground for fixation. The second umbrella rod 420 is connected with the canopy 430. The orientation of the canopy 430 is adjusted by adjusting the relative angle between the first connecting member 100 and the second connecting member 200.

[0067] The rotation angle adjusting device of the present application drives the locking member to move, and under the action of the inclined surface, the locking member can quickly move between the locking position and the unlocking position. Compared with the existing threaded connection form, the speed of locking and unlocking operation is improved.

[0068] The technical features of the above embodiments can be combined in any manner.
