[0027] To facilitate understanding of the embodiments of the present invention, a more complete description of the embodiments will be given below with reference to the accompanying drawings. Preferred embodiments of the present invention are shown in the drawings. However, the present invention can be implemented in many different forms and is not limited to the embodiments described herein. Rather, these embodiments are provided to provide a thorough and complete understanding of the disclosure of the present invention.

[0028] 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 invention pertains. The terminology used herein in the embodiments of the invention is for the purpose of describing particular implementations only and is not intended to limit the invention.

[0029] Please see Figure 1 This invention provides a toggle hook 10, including a rotating sleeve 11, a sliding member 13, and a latch 14. The sliding member 13 is located inside the rotating sleeve 11 and can move along the axis of the rotating sleeve 11. The latch 14 is connected to the sliding member 13 and extends out of the rotating sleeve 11, so that the latch 14 can move relative to the rotating sleeve 11 along the axis of the rotating sleeve 11 due to the driving of the sliding member 13. This allows for convenient adjustment of the distance between the latch 14 and the rotating sleeve 11 as needed. In other words, the distance between the latch 14 and the rotating sleeve 11 can be adaptively adjusted according to the width of the object to be latched, so as to conveniently achieve the engagement and fixation or separation of the toggle hook 10 and the object to be latched. The operation is one-step, convenient and simple, and can quickly lock or unlock. In this embodiment, with the hook 14 fixed (e.g., held by hand), the rotating sleeve 11 can be rotated to drive the sliding member 13 to move relative to the rotating sleeve 11 along the axis of the rotating sleeve 11, so that the rotating sleeve 11 moves relative to the hook 14 along the axis of the rotating sleeve 11.

[0030] In some other embodiments, the toggle hook 10 may also include a housing 15. The housing 15 is, for example, a generally hollow cylindrical structure. The housing 15 can be used to house the rotating sleeve 11 and the sliding member 13. The rotating sleeve 11 is rotatably mounted in the housing 15. When the rotating sleeve 11 rotates relative to the housing 15, the sliding member 13 can move along the axis of the rotating sleeve 11, thereby driving the hook 14 to move along the axis of the rotating sleeve 11. This allows for convenient adjustment of the distance between the hook 14 and the rotating sleeve 11 as needed. In other words, the distance between the hook 14 and the rotating sleeve 11 can be adaptively adjusted according to the width of the object to be locked, so as to conveniently achieve the engagement and locking or disengagement of the toggle hook 10 with the object to be locked. The operation is one-step, convenient and simple, and can quickly lock or unlock.

[0031] Please see Figure 2 and Figure 3 The rotating sleeve 11 is generally a cylindrical structure with openings at both ends. The rotating sleeve 11 includes a first end 112 and a second end 114. In this embodiment, the first end 112 can abut against the object to be locked when the lever hook 10 is engaged. The second end 114 is opposite to the first end 112, and an arc-shaped groove 1141 can be formed in the second end 114. Figure 6The arc groove 1141 can be a closed ring. In other embodiments, there can be one or more arc grooves 1141, and the multiple arc grooves 1141 can also be in a discontinuous ring shape.

[0032] The inner surface of the rotating sleeve 11 is provided with a spiral groove 115, which extends spirally from the first end 112 to the second end 114 around the axis of the rotating sleeve 11. The helix angle of the spiral groove 115 can be set according to specific requirements. The spiral groove 115 can be used to install the sliding member 13, so that with the sliding member 13 fixed, the sliding member 13 can move along the axis of the rotating sleeve 11 as the rotating sleeve 11 rotates. That is, the sliding member 13 can drive the hook 14 to move relative to the rotating sleeve 11, thereby conveniently adjusting the distance between the hook 14 and the rotating sleeve 11 as needed. In other words, the distance between the hook 14 and the rotating sleeve 11 can be adjusted by rotating the rotating sleeve 11 by setting an angle according to the width of the object to be locked, so as to conveniently achieve the locking and locking or separation of the toggle hook 10 and the object to be locked. The operation is one step in a row, which is convenient and simple, and can quickly lock or unlock the toggle hook 10.

[0033] In this embodiment, the inner surface of the rotating sleeve 11 is also provided with a first groove 116 and a second groove 118. The first groove 116 passes through the first end 112 and communicates with the spiral groove 115. The second groove 118 is disposed at the second end 114 and communicates with the spiral groove 115. The first groove 116 and the second groove 118 extend along the circumference of the rotating sleeve 11. Since both the first slot 116 and the second slot 118 are connected to the spiral groove 115, when the sliding member 13 can slide through the spiral groove 115 to engage with the first slot 116 or the second slot 118, and the first slot 116 and the second slot 118 extend circumferentially along the rotating sleeve 11, when the sliding member 13 engages with the first slot 116, the sliding member 13 engages between the bottom surface of the first slot 116 and the housing 15; or when the sliding member 13 engages with the second slot 118, the sliding member 13 engages between the top surface and the bottom surface of the second slot 118, preventing the force along the axis of the rotating sleeve 11 from causing the slider 132 to move, that is, achieving self-locking of the sliding member 13. In this embodiment, the first slot 116 and the second slot 118 extend in opposite directions, wherein the first slot 116 extends along the circumferential direction of the spiral groove 115. Figure 3 Extending the viewpoint counterclockwise, the second card slot 118 along... Figure 3Extending the viewing angle clockwise, the angle between the first groove 116 and the spiral groove 115 is obtuse, and the angle between the second groove 118 and the spiral groove 115 is also obtuse. This reduces the resistance encountered when the sliding member 13 slides through the spiral groove 115 to engage with the first groove 116 or the second groove 118 during the rotation of the rotating sleeve 11. In other embodiments, the first groove 116 and the second groove 118 may also extend in the same direction.

[0034] Please continue reading. Figure 2 and Figure 3 The slider 13 includes a slider 132 and a protrusion 134. The protrusion 134 is connected to the slider 132 and slidably mounted in the helical groove 115, so that the rotation of the rotating sleeve 11 can drive the slider 13 to move along the axis of the rotating sleeve 11. In this embodiment, the slider 132 is generally cylindrical, and the protrusion 134 protrudes from the outer surface of the slider 132.

[0035] The slider 132 is provided with a first sliding hole 1321 and a second sliding hole 1322. The first sliding hole 1321 and the second sliding hole 1322 can be used for positioning the slider 132, so that when the rotating sleeve 11 rotates, the slider 13 cannot rotate relative to the rotating sleeve 11, but can only move along the axis of the rotating sleeve 11.

[0036] The slider 132 also has a first through hole 1323, which can be used for the hook 14 to pass through. In this embodiment, the first through hole 1323 is located between the first sliding hole 1321 and the second sliding hole 1322, and the second sliding hole 1322 is a rectangular hole. In other embodiments, the first through hole 1323 can also be provided at other positions of the slider 132, and the first through hole 1323 can also be a circular hole, an elliptical hole, or a hole of other shapes, as long as it can accommodate the hook 14.

[0037] Please continue reading. Figure 1 and Figure 2The hook 14 includes a hook body 141, an elastically deformable part 143, and a hook mounting part 145. The hook mounting part 145 is connected to the slider 132. The hook mounting part 145 can be connected to the slider 132 by screws or by adhesive. The hook body 141 extends beyond the rotating sleeve 11. The hook body 141 can pass through the first through hole 1323 and protrude beyond the housing 15. The hook body 141 may include a hook to facilitate engaging with the item to be engaged (e.g., an air vent blade of an automobile). The elastic deformation portion 143 connects the hook mounting portion 145 and the hook body portion 141. The elastic deformation portion 143 can be bent relative to the hook body portion 141 and the hook mounting portion 145, so that the elastic deformation portion 143 has elastic deformation along the axial direction of the rotating sleeve 11, and provides a force to retract the hook body portion 141, thereby facilitating the clamping of the hook 14 with the object to be clamped. It should be noted that by setting the elastic deformation portion 143, the clamping effect of the pull hook 10 can be improved. Moreover, compared with setting a spring separately, the elastic deformation portion 143 can cleverly combine the elastic element such as the spring with the hook structure without setting an additional elastic element, simplifying the structure and saving costs. In this embodiment, the elastic deformation portion 143 is located inside the rotating sleeve 11. In other embodiments, the elastic deformation portion 143 may also be located outside the rotating sleeve 11.

[0038] Please continue reading. Figure 2 The housing 15 includes a first housing 151 and a second housing 155, with the second housing 155 detachably connected to the first housing 151. In this embodiment, the connection between the first housing 151 and the second housing 155 can be a threaded connection. In other embodiments, the connection between the first housing 151 and the second housing 155 can also be a snap-fit ​​or other detachable connection methods.

[0039] The first housing 151 is rotatably mounted on the first end 112 of the rotating sleeve 11 relative to the rotating sleeve 11. Specifically, the first housing 151 includes a first bottom wall 1510 and a first side wall 1520. The first bottom wall 1510 is located at one end of the rotating sleeve 11, and the first side wall 1520 is connected to the first bottom wall 1510 and sleeved on the outer surface of the rotating sleeve 11. The first bottom wall 1510 is provided with a second through hole 1512, which can correspond to the position of the first through hole 1323. The second through hole 1512 can also be used for the insertion of the hook 14, that is, the hook 14 can extend out of the first housing 151 through the first through hole 1323 and the second through hole 1512 in sequence. The first side wall 1520 is provided with an opening 1522, through which the rotating sleeve 11 can be exposed, so that the user can operate the rotating sleeve 11 to rotate through the opening 1522. The first sidewall 1520 may also be provided with multiple anti-slip grooves 1514 to facilitate user hand grip.

[0040] Please see Figure 4 , Figure 5 and Figure 6 The first housing 151 also includes a first positioning rod 1530 and a second positioning rod 1540, which are spaced apart from each other and connected to the side of the first bottom wall 1510 facing the second housing 155. The length direction of the first positioning rod 1530 and the second positioning rod 1540 is consistent with the axial direction of the rotating sleeve 11. The first positioning rod 1530 and the second positioning rod 1540 can be used to limit the slider 132, so that the slider 132 can only move along the extension direction of the first positioning rod 1530 (the second positioning rod 1540) (that is, the direction of the axial direction of the rotating sleeve 11) under the drive of the rotating sleeve 11, and will not rotate with the rotating sleeve 11. Specifically, the first positioning rod 1530 passes through the first sliding hole 1321 and is connected to the first positioning rod connecting part 1554, thereby connecting to the second housing 155, wherein the connection method can be a threaded connection. The second positioning rod 1540 passes through the second sliding hole 1322 and is connected to the second positioning rod connecting part 1556 and the second housing 155. The connection method can be a threaded connection.

[0041] The second housing 155 is rotatably mounted on the second end 114 of the rotating sleeve 11 relative to the rotating sleeve 11. The second housing 155 can cooperate with the first housing 151 to jointly house the rotating sleeve 11 and the sliding member 13. Specifically, the second housing 155 includes a second bottom wall 1550 and a second side wall 1553. The second bottom wall 1550 is located at the end of the rotating sleeve 11 away from the first bottom wall 1510. An arc-shaped guide rail 1552 can be provided on the side of the second bottom wall 1550 facing the first bottom wall 1510. The arc-shaped guide rail 1552 can be arranged around the axis of the rotating sleeve 11. The arc-shaped guide rail 1552 can cooperate with the arc-shaped groove 1141 to limit the radial movement of the rotating sleeve 11, so that the rotating sleeve 11 can only rotate relative to the second housing 155. In this embodiment, the arc-shaped guide rail 1552 can be in the form of a closed ring. In other embodiments, there may be one or more arc-shaped guide rails 1552, which may form discontinuous rings. The specific structure of the arc-shaped guide rails 1552 can be set according to actual conditions, as long as they cooperate with the arc-shaped groove 1141 and allow the rotating sleeve 11 to rotate relative to the second housing 155. The second sidewall 1553 is connected between the second bottom wall 1550 and the first sidewall 1520, and the second sidewall 1553 corresponds to the outer surface of the rotating sleeve 11. The second sidewall 1553 may also be provided with multiple anti-slip grooves to facilitate user grip.

[0042] The second housing 155 also includes a first positioning rod connecting portion 1554 and a second positioning rod connecting portion 1556. The first positioning rod connecting portion 1554 is disposed on the side of the second bottom wall 1550 facing the first bottom wall 1510 and can be used to connect with the first positioning rod 1530. The second positioning rod connecting portion 1556 is disposed on the side of the second bottom wall 1550 facing the first bottom wall 1510 and can be used to connect with the second positioning rod 1540. In this embodiment, the first positioning rod connecting portion 1554 is threadedly connected to the first positioning rod 1530. Specifically, the first positioning rod 1530 can have a threaded hole, and the first positioning rod connecting portion 1554 can have a through hole. By screwing a screw through the through hole and engaging with the threaded hole, the threaded connection between the first positioning rod connecting portion 1554 and the first positioning rod 1530 can be achieved. The second positioning rod connecting portion 1556 and the second positioning rod 1540 can also be connected by the above-described threaded connection method. In other embodiments, the first positioning rod connecting portion 1554 may have a groove, so that the first positioning rod 1530 can be installed in the groove by interference fit.

[0043] Please see Figure 1 , Figure 2 and Figure 4 The lever-type hook 10 also includes a rotating operating member 16, which is connected to the outer surface of the rotating sleeve 11. The rotating operating member 16 extends outward from the opening 1522, so the user can rotate the rotating sleeve 11 by rotating the operating member 16. In this embodiment, the rotating operating member 16 has a plate-like structure and protrudes radially from the outer surface of the rotating sleeve 11, which can increase the force-bearing area and facilitate the user's lever operation.

[0044] The lever-type hook 10 also includes an operating part 17, which is connected to the outer surface of the housing 15. Through the cooperation of the operating part 17 and the rotating operating member 16, the user can operate the rotating operating member 16 with one hand to rotate the rotating sleeve 11. In this embodiment, the operating part 17 and the rotating operating member 16 are spaced apart around the axis of the rotating sleeve 11; that is, the operating part 17 and the rotating operating member 16 are located circumferentially around the rotating sleeve 11, so that the force direction of the rotating sleeve 11 can be consistent with the rotation direction of the rotating sleeve 11, making operation more effortless. The operating part 17 is also a plate-like structure and protrudes radially from the outer surface of the first sidewall 1520 along the rotating sleeve 11, which can also increase the force-bearing area and facilitate the user's lever operation.

[0045] Please continue reading. Figure 5 In this embodiment, the toggle hook 10 also includes a universal ball joint 19, which is connected to the second housing 155 and located on the side of the second housing 155 opposite to the rotating sleeve 11. The universal ball joint 19 can be used to connect with a bracket, which can be used to mount a mobile phone to fix the phone in place.

[0046] Please see Figure 7 In some other embodiments, the housing 15 may be omitted; that is, the toggle hook 10 may only include a rotating sleeve 11, a sliding member 13, and a latch 14. With the latch 14 fixed (e.g., by hand), rotating the rotating sleeve 11 causes the sliding member 13 to move relative to the rotating sleeve 11 along the axis of the rotating sleeve 11, thereby causing the rotating sleeve 11 to move relative to the latch 14 along the axis of the rotating sleeve 11.

[0047] In summary, the toggle hook 10 of this embodiment includes a rotating sleeve 11, a sliding member 13, and a latch 14. The inner surface of the rotating sleeve 11 is provided with a spiral groove 115, which extends spirally from the first end 112 to the second end 114 of the rotating sleeve 11 around its axis. The sliding member 13 is located inside the rotating sleeve 11 and includes a slider 132 and a protrusion 134 connected to the slider 132. The protrusion 134 is slidably mounted in the spiral groove 115. The rotation of the rotating sleeve 11 drives the sliding member 13 along the rotating sleeve... The axis of 11 moves, the hook 14 is connected to the sliding member 13 and extends out of the rotating sleeve 11. The protrusion 134 slides along the spiral groove 115, so that the sliding member 13 can drive the hook 14 to move relative to the rotating sleeve 11 along the axis of the rotating sleeve 11. Thus, the distance between the hook 14 and the rotating sleeve 11 can be conveniently adjusted according to the width of the object to be locked, so as to conveniently realize the locking and fixing or separation of the toggle hook 10 and the object to be locked. The operation is one step, convenient and simple, and can quickly lock or unlock the toggle hook 10.

[0048] Please see Figure 8 The present invention also provides a mobile phone holder 1, including a mounting bracket 20 and a toggle hook 10, wherein the mounting bracket 20 is adapted to be connected to the toggle hook 10.
