Referring to fig. 1 to 3, an embodiment of a quick release handle structure is shown, which mainly includes a positioning shaft 10 and a control rod 21 detachably locked to the positioning shaft 10, wherein a middle section of the positioning shaft 10 can penetrate through a positioning axle (not shown) of two front wheels or a rear wheel frame of a bicycle to position a wheel, and when the control rod 21 is locked to the positioning shaft, a user can lock the other end of the positioning shaft 10 through the control rod 21 to complete the installation of the wheel.

The positioning shaft 10 has a groove 11 extending axially, the middle section and the bottom of the groove 11 are respectively defined as an installation section 13 and a fixed section 14, wherein the aperture of the installation section 13 is larger than that of the fixed section 14.

One end of the control rod 21 is provided with a handle 20, the other end of the control rod is provided with a clamping and stopping section 25 to match with the fixed section 14, the main body of the middle section of the control rod 21 is a cylinder 22, one part of the cylinder 22 radially protrudes to form an octagonal positioning part 23, and the section of the cylinder 22 is an inscribed circle of the section of the octagonal positioning part 23. In addition, the control rod 21 is provided with a groove 26 on the surface of the cylinder 22 near the stop section 25 for positioning a C-shaped baffle 50. In this embodiment, the C-shaped flap 50 is laterally slid into and mounted in the groove 26 by a plurality of protrusions 51 projecting outwardly from its inner edge.

The middle section of the control rod 21 is provided with a thread sleeve 30, the thread sleeve 30 is provided with an external thread 311 to be locked on the opening 12 of the groove body 11, at least one part of the contour of the inner wall 312 of the thread sleeve 30 is in accordance with the surface of the positioning part 23, and the (axial) thickness of the thread sleeve 30 is larger than that of the positioning part 23. When the control rod 21 moves along the inner wall 312 of the thread sleeve 30 in the radial direction, the cylinder 22 is smaller than the inner wall 312 of the thread sleeve 30, so that the control rod 21 can slide or rotate in the inner wall 312 of the thread sleeve 30, however, when the positioning portion 23 of the control rod 21 slides to the thread sleeve 30, the surface of the positioning portion 23 is engaged with the inner wall 312 of the thread sleeve 30, so that the rotation torque of the control rod 21 can be transmitted to the thread sleeve 30, and at this time, the control rod 21 can drive the thread sleeve 30 to rotate synchronously. The positioning portion 23 and the thread sleeve 30 may be engaged with each other by a plurality of teeth, and the same effect is obtained.

The control rod 21 is sleeved with a conical helical spring 40 which abuts against and is positioned between the C-shaped baffle 50 and the thread sleeve 30, and an opening of the spring 40 abutting against the C-shaped baffle 50 is smaller than an opening of the spring 40 abutting against the thread sleeve 30, so that the inner part of the helical spring 40 is spaced from the positioning part 23.

The fixing section 14 of the slot 11 has an annular rib inner wall 143 adjacent to the bottom of the slot 11 and an annular smooth inner wall 142 at the fixing section opening 141 between the rib inner wall 143 and the mounting section. The inner wall 143 of the protruding rib is a plurality of protruding ribs protruding along the axis of the groove body and arranged at equal angles, and the inner wall 143 of the protruding rib is matched with the plurality of guide grooves 251 at the bottom end of the stop section 25 of the control rod 21. Therefore, the locking section 25 of the control lever 21 can be completely locked on the inner wall 143 of the rib at the bottom of the groove body 11 when the control lever is rotated to a specific angle.

Referring to fig. 3, when the quick release handle is locked, the control rod 21 is located in the groove 11 of the positioning shaft 10, the mounting section 13 of the groove 11 accommodates the middle section of the control rod 21, the thread sleeve 30 is locked in the opening 12 of the groove 11, the C-shaped baffle 50 is located in the opening 141 of the fixing section, and the locking section 25 at the rear end of the control rod 21 is locked in the fixing section 14 of the groove 11, so that the spring 40 is kept in a released state (i.e., is not elastically deformed). And, because the quick detach handle only uses an axially extended control lever to drive other subassemblies, more can easy to assemble and improve structural strength simultaneously.

Referring to fig. 4, a process of the quick release handle of fig. 1 is shown.

When the quick release handle is locked, a user can apply force to the control rod 21 through the handle 20 to enable the clamping section 25 to be separated from the inner wall 143 of the convex rib, the handle 20 is rotated to enable the bottom of the clamping section 25 to be staggered with the top of the inner wall 143 of the convex rib, the clamping section 25 is abutted against the smooth side wall, and the first section of unlocking is completed. During the axial displacement of the control rod 21, the spring 40 between the thread set 30 and the flap 50 is compressed because the flap 50 also moves relative to the thread set 30. At this stage, the user can freely adjust the angle of the handle 20 to a proper position, and once the force application is stopped, the elastic potential of the spring 40 is released to automatically reset the control lever 21.

When the user wants to remove the handle 20, the user can continuously pull out the control rod 21, and continuously slide the control rod 21 relative to the thread sleeve 30, so as to move the positioning portion 23 at the middle section of the control rod 21 toward the thread sleeve 30, and at this time, the C-shaped stopper 50 is also moved relative to the thread sleeve 30 and presses the spring 40. When the thread external member 30 is sleeved on the positioning portion 23, the user can drive the thread external member 30 to synchronously rotate through the handle 20, the thread external member 30 is detached from the groove body opening 12, the second section of unlocking is completed, at the moment, the spring 40 releases the elastic potential energy, and other parts of the control rod 21 are ejected out of the groove body 11 of the positioning shaft to complete detachment.

Referring to fig. 5 and 6, another embodiment of the quick release handle structure is shown, in this embodiment, an annular groove 121 is radially recessed in the inner wall of the opening 12 of the groove 11 for installing the O-ring 70 as a sealing member. One end of the control rod 21 is provided with a handle 20, the main body of the middle section of the control rod 21 is a cylinder 22, the surface of the cylinder 22 is sequentially provided with and positioned with the sleeve member 60, the spring 40 and the annular baffle 50, and then is sleeved with a hexagon nut to form a clamping section 25.

In the embodiment, the sleeve member 60 has a top cover and is sleeved on the cylinder 22 through the through hole of the top cover, and the annular side wall extends from one side of the top cover and is spaced apart from the surface of the cylinder 22, the outer diameter of the spring 40 is smaller than the inner wall 61 of the annular side wall, and the outer diameter of the annular elastic piece 50 is larger than the diameter of the inner wall 61 of the annular side wall. Therefore, in the locked state, one end of the spring 40 can abut against the top cover of the sleeve 60, and a part of the spring 40 can be accommodated between the inner wall 61 of the annular side wall of the sleeve 60 and the cylinder 22. Compared with the previous embodiment, this embodiment can also maintain the spring 40 in the released state while shortening the length of the middle section of the control end 21.

The outer wall 62 of the annular side wall of the sleeve 60 can axially displace along the inner wall of the opening 12 of the tank body 11, and in addition, the outer wall 62 of the sleeve 60 is further provided with an annular groove 65 for matching with the O-ring 70 of the opening 12 of the tank body 11, so that the sleeve 60 can be positioned at the opening 12 of the tank body 11 to form a locking state. In addition, the handle 20 is provided with a through hole as a mounting portion for positioning the front end of the control rod 21, so that the sleeve 60 can be accommodated in the space formed by the through hole of the handle 20 and the opening 12 of the slot body 11 to position the handle 20 and the slot body 11 in the locked state.

Referring to fig. 7, a process of the step unlocking of the quick release handle structure of fig. 5 is shown.

In the present embodiment, the procedure of the first stage unlocking is similar to the previous embodiment, and the user can apply a force through the handle 20 to disengage the locking section 25 of the control lever 21 from the fixing section 14 of the slot body 11, so as to adjust the angle of the handle 20. During the axial displacement of the control rod 21, the ring-shaped elastic piece 50 slides relative to the sleeve 60 and presses the spring 40, and once the application of force is stopped, the control rod 21 automatically resets.

If the user wants to detach the handle 20, the control rod can be pulled out continuously, and at this time, because the outer diameter of the ring-shaped elastic piece 50 is larger than the inner diameter of the ring-shaped side wall of the sleeve member 60, the ring-shaped elastic piece 50 will first completely press the spring 40 in the sleeve member 60, and then be clamped at one side of the sleeve member 60, and push the sleeve member 60 to axially slide toward the opening of the slot body 11. When the annular side wall of the sleeve 60 is completely separated from the opening 12 of the slot body 11, the spring 40 releases the elastic potential energy to eject the other part of the control rod 21 out of the slot body 11 of the positioning shaft. Compared with the former embodiment, the user can finish the disassembly by pulling the control rod 21 out of the opening 12 of the slot body 11 by the handle 20, which is more convenient.

The above-described embodiments and/or implementations are only illustrative of the preferred embodiments and/or implementations for implementing the technology of the present application, and are not intended to limit the implementations of the technology of the present application in any way, and those skilled in the art can make many changes or modifications to the equivalent embodiments without departing from the scope of the technology disclosed in the present application, but should still be considered as the technology or implementations substantially the same as the present application.
