Description

Technical Field

[0001] This utility model relates to the field of bicycle technology, and in particular to a quick-release pedal structure. Background Technology

[0002] Pedals are the components in a bicycle's drivetrain that come into direct contact with the rider's feet. They efficiently convert the rider's pedaling force into rotational force that propels the bicycle forward via the crank and chainring. To meet the convenience and functionality requirements of modern cyclists, quick-release pedals were developed, allowing riders to quickly remove or reinstall the pedals from the crank without using any tools.

[0003] However, existing quick-release pedals are often quite complex, and the connecting parts used to insert into the pedals are difficult to remove from the crank, causing inconvenience for subsequent maintenance. Utility Model Content

[0004] To solve the above-mentioned technical problems, this utility model provides a quick-release foot pedal structure that is easy to disassemble.

[0005] The present invention adopts the following technical solution:

[0006] This utility model provides a quick-release pedal structure, including a crank, a pedal, a pedal sleeve, and an unlocking control. The pedal sleeve is threadedly connected to the crank and has a release part formed on the side of the crank away from the pedal. The pedal is inserted into the pedal sleeve. The unlocking control is rotatably fitted on the pedal sleeve and located on the side of the crank near the pedal. The pedal sleeve accommodates a limiting member that can move radially. The bottom end of the limiting member is located in the annular groove of the pedal and can move away from the annular groove with the axial movement of the pedal. The unlocking control is continuously provided with a locking part and a clearance part. When the unlocking control is rotated so that the locking part reaches the limiting member, the locking part locks the limiting member in the annular groove. When the unlocking control is rotated so that the clearance part reaches the limiting member, a gap is formed between the clearance part and the limiting member that can accommodate the limiting member.

[0007] Preferably, the disassembly part is located inside the crank, and a force-receiving groove is provided in the recess of the disassembly part.

[0008] Preferably, the disassembly part extends through the crank and has a pair of force-bearing planes spaced parallel to each other on it.

[0009] Preferably, the foot pedal has a first step, a second step, and a third step with successively increasing diameters. The crank is threadedly connected to the first step through a connecting hole. The unlocking control is sleeved on the second step and is axially limited between the crank and the third step.

[0010] Preferably, the unlocking control is ring-shaped.

[0011] Preferably, the unlocking control component has multiple weight-reducing holes spaced at equal intervals in a circumferential direction, and each weight-reducing hole is hollowed out along the axial direction.

[0012] Preferably, the two axial sides of the unlocking control component are detachably connected to cover plates, which completely cover the two axial sides of the unlocking control component.

[0013] Preferably, the unlocking control is connected to the foot pedal sleeve via a torsion spring. When the torsion spring is in its natural state, the locking part of the unlocking control locks the limiting member in the annular groove.

[0014] Preferably, the groove of the annular groove has a minor arc shape, the limiting element is a rolling element, and the assembly hole of the unlocking control element is provided with a clearance space. The clearance space gradually expands around the rotation direction of the unlocking control element, with the bottom end of the clearance space being the locking part and the top end being the clearance part.

[0015] Preferably, the assembly hole of the unlocking control component is provided with an axially penetrating clearance hole, the shape of which is adapted to the top shape of the limiting component.

[0016] Compared with the prior art, the beneficial effects of this utility model are as follows:

[0017] In use, the quick-release pedal structure of this utility model allows the locking part to reach the limiting part by rotating the unlocking control component. The locking part then locks the limiting part in the annular groove of the pedal, thus locking the pedal and crank. After rotating the unlocking control component to reach the limiting part, a gap is formed between the limiting part and the limiting part to accommodate the limiting part. Then, the pedal can be pulled out of the pedal sleeve to release the lock between the pedal and crank, achieving quick release of the pedal.

[0018] Furthermore, since the pedal sleeves are threaded to the crank, they can be quickly removed during maintenance by inserting a disassembly tool into the disassembly section. Additionally, the disassembly section is located on the crank side away from the pedals, which also provides protection for it. Attached Figure Description

[0033] Furthermore, in the description of this utility model, unless otherwise stated, "a plurality of" means two or more.

[0034] See Figure 1 , Figure 4 , Figure 8 and Figure 9 This embodiment provides a quick-release pedal structure, including a crank 1, a pedal 2, a pedal sleeve 3, and an unlocking control 4. The pedal sleeve 3 is threaded to the crank 1 and has a release portion formed on the side of the crank 1 away from the pedal. The pedal 2 passes through the pedal sleeve 3. The unlocking control 4 is rotatably fitted on the pedal sleeve 3 and located on the side of the crank 1 near the pedal 2. The pedal sleeve 3 accommodates a radially movable limiting member 5, the bottom end of which is located in the annular groove 20 of the pedal 2. The foot pedal 2 moves axially and disengages from the annular groove 201. The unlocking control 4 is continuously provided with a locking part 401 and a clearance part 402. When the unlocking control 4 is rotated so that the locking part 401 reaches the limit member 5, the locking part 401 locks the limit member 5 in the annular groove 201. When the unlocking control 4 is rotated so that the clearance part 402 reaches the limit member 5, a gap is formed between the clearance part 402 and the limit member 5 that can accommodate the limit member 5.

[0035] In this embodiment, when the quick-release pedal structure is in use, the locking part 401 is moved to the limiting part 5 by rotating the unlocking control 4. The locking part 401 locks the limiting part 5 in the annular groove 201 of the pedal 2, thereby locking the pedal 2 and the crank 1. After the clearance part 402 is moved to the limiting part 5 by rotating the unlocking control 4, a gap is formed between the clearance part 402 and the limiting part 5 that can accommodate the limiting part 5. Then the pedal 2 can be pulled out from the pedal sleeve 3 to release the lock between the pedal 2 and the crank 1, thus achieving quick release of the pedal 2.

[0036] Meanwhile, since the pedal sleeve 3 is threadedly connected to the crank 1, the pedal sleeve 3 can be quickly removed during maintenance by inserting a disassembly tool into the disassembly part 301 of the pedal sleeve 3. In addition, the disassembly part 301 is located on the side of the crank 1 away from the pedal, which also protects the disassembly part 301.

[0037] Better yet, see Figure 3 and Figure 8 In this embodiment, the foot pedal 2 includes a foot pedal shaft 202 and a foot pedal 203. One end of the foot pedal shaft 202 is rotatably connected to the foot pedal 203, and the other end of the foot pedal shaft 202 is inserted into the foot pedal sleeve 3.

[0038] Preferably, in this embodiment, the diameter of the pedal shaft 202 at the end away from the pedal 203 is larger than the diameter at the end closer to the pedal 203, so that the end of the pedal shaft 202 away from the pedal 203 (crank end) has sufficient bending strength and rigidity to prevent the pedal shaft 202 from deforming or breaking.

[0039] Better yet, see Figure 3 In this embodiment, the foot pedal 203 is provided with positioning protrusions 204 at intervals on the outer edge of the top and bottom surfaces to increase the friction between the foot pedal 203 and the rider's shoe sole, making riding easier.

[0040] Preferably, see Figure 6 and Figure 7 The disassembly part 301 is located inside the crank 1. The disassembly part 301 is provided with a force groove, so that the disassembly can be completed by inserting the disassembly tool into the force groove and then rotating the disassembly tool.

[0041] Specifically, the force-bearing groove can be a hexagonal groove, and in this case, an internal hex wrench should be selected to complete the disassembly.

[0042] Preferably, see Figures 3 to 5 The disassembly part 301 extends through the crank 1. A pair of force-bearing planes are arranged parallel to each other on the disassembly part 301. The disassembly part 301 can be disassembled by pressing the pair of force-bearing planes on the disassembly part 301 with a wrench and then turning the wrench.

[0043] Preferably, see Figure 1 , Figure 2 and Figure 5 The foot pedal 3 has a first step 302, a second step 303, and a third step 304 with successively increasing diameters. The crank 1 is threadedly connected to the first step 302 through the connecting hole 101. The unlocking control 4 is sleeved on the second step 303 and is axially limited between the crank 1 and the third step 304.

[0044] Preferably, see Figure 9 The unlocking control 4 is ring-shaped to facilitate manual twisting.

[0045] Preferably, in this embodiment, the outer peripheral surface of the unlocking control 4 is provided with anti-slip knurling, thereby further improving the convenience of manually turning the unlocking control 4.

[0046] Preferably, see Figure 4 and Figure 9 The unlocking control component 4 has multiple weight reduction holes 403 spaced out in a circumferential direction, and each weight reduction hole 403 is hollowed out along the axial direction.

[0047] Specifically, see Figure 9 In this embodiment, the unlocking control component 4 has three weight-reducing holes 403.

[0048] Preferably, see Figure 3 The unlocking control component 4 has detachable cover plates 6 on both sides along the axial direction. The cover plates 6 completely cover both sides of the unlocking control component 4 along the axial direction to prevent contaminants from entering the unlocking control component 4 and to ensure the long-term normal use of the unlocking control component 4.

[0049] Specifically, in this embodiment, the cover plates 6 on both sides of the unlocking control 4 are fastened by three screws.

[0050] Preferably, see Figure 4 and Figure 9 The unlocking control 4 is connected to the pedal sleeve 3 via a torsion spring 7. When the torsion spring 7 is in its natural state, the locking part 401 of the unlocking control 4 locks the limiting member 5 in the annular groove 201. Thus, the locking part 401 on the unlocking control 4 is kept in the state of locking the limiting member 5 in the annular groove 201 by the torsion spring 7, ensuring the locking effect between the pedal 2 and the crank 1, making riding safer.

[0051] Preferably, see Figure 8 and Figure 9 The groove of the annular groove 201 has a sloping arc shape. The limiting part 5 is a rolling body. The mounting hole 404 of the unlocking control part 4 is provided with a clearance space 405. The clearance space 405 gradually expands around the rotation direction of the unlocking control part 4. The bottom end of the clearance space 405 is the locking part 401 and the top end is the clearance part 402.

[0052] When it is necessary to unlock pedal 2 from crank 1, manually turn unlock control 4 to deflect it so that the top of clearance space 405 (i.e. clearance part) reaches limit member 5. Then manually pull pedal 2. Because the groove of annular groove 201 has a sloping arc shape, when pedal 2 is pulled outward, the limit member 5 in annular groove 201 will gradually move out and enter clearance space 405, thereby realizing quick release of pedal 2.

[0053] Preferably, in this embodiment, the limiting member 5 is a sphere, specifically a steel ball.

[0054] Preferably, see Figure 9The unlocking control component 4 has an axially penetrating clearance hole 406 inside its mounting hole 404. The shape of the clearance hole 406 is adapted to the top shape of the limiting component 5. When the unlocking control component 4 is assembled onto the foot pedal cover 3, the clearance hole 406 can be adjusted to face the limiting component 5, thereby avoiding the limiting component 5 and facilitating assembly.

[0055] Better yet, see Figure 4 , Figure 5 and Figure 9 In this embodiment, the foot pedal sleeve 3 is provided with a plurality of radially penetrating receiving holes 305 at equal intervals around its outer periphery. Each receiving hole 305 contains a limiting member 5. The mounting hole 404 of the unlocking control member 4 is provided with a plurality of clearance spaces 405 at equal intervals around its outer periphery. The clearance spaces 405 correspond one-to-one with the limiting members 5.

[0056] Preferably, in this embodiment, the mounting hole 404 of the unlocking control member 4 is provided with a plurality of clearance holes 406 at equal intervals in the circumferential direction, and the clearance holes 406 correspond one-to-one with the receiving holes 305.

[0057] Specifically, in this embodiment, the foot pedal sleeve 3 has three receiving holes 305 and the unlocking control 4 has three clearance holes 406.

[0058] The above description is only a preferred embodiment of the present utility model. It should be noted that for those skilled in the art, several improvements and substitutions can be made without departing from the technical principles of the present utility model, and these improvements and substitutions should also be considered within the protection scope of the present utility model.
