Description

Technical Field

[0001] This utility model relates to the technical field of foot pedals, and in particular to a foot pedal with adjustable spacing. Background Technology

[0002] Bicycles are a common mode of transportation in daily life, and the pedals are an important part of the drive mechanism. Currently, bicycle pedals are fixed to the crankshaft and connecting rod via a spindle. Stepping on the pedals rotates the crankshaft and connecting rod, which in turn drives the sprocket. Existing pedals are usually fixed to the crankshaft and connecting rod. Because the length of the pedals cannot be adjusted, smaller pedals are prone to slipping off the foot, and one side of the pedal being too close to the crankshaft and connecting rod not only causes a heavy feeling during riding but also makes it easy for the pedals to rub against clothing and reduces the contact area with the foot.

[0003] Chinese Patent Announcement No. CN210882485U, Announcement Date: June 30, 2020, discloses an adjustable foot pedal, including a pedal body. The pedal body is characterized by: a connecting rod extending to the left side of the pedal body at one end fixedly connected inside; storage slots on both the upper and lower sides of the pedal body; adjustment holes located inside the pedal body on the right side walls of the inner cavities of both storage slots; widening plates movably installed inside both storage slots; and adjustment rods extending through the adjustment holes and to the right side of the pedal body at one end fixedly installed on the right side of each of the two widening plates; and thrust blocks fixedly installed on the right sides of each of the two adjustment rods. Each of the widened plates has an adjustment groove on its left side. The pedal body has four mounting holes on its left side, each communicating with one of the two storage slots. A mounting cover is fixedly installed inside each of the two adjustment grooves. A spring telescopic rod is fixedly installed on the right side wall of the inner cavity of each of the two mounting covers. A limiting block extending into the mounting hole is fixedly installed on the left side of each of the two spring telescopic rods. A stop block is fixedly installed on the inner side wall of each of the four mounting holes. A push rod, with one end penetrating the mounting hole and extending to the left side of the pedal body and the other end extending to the right side of the stop block, is movably connected inside each of the four stop blocks. A pressing block located inside the mounting hole is fixedly installed on the right side of each of the four push rods. The drawback of this invention is that the pedal is adjusted by changing the installation position of the widened plate, making it difficult to meet more adjustment needs. Utility Model Content

[0004] The present invention aims to overcome the shortcomings of existing non-adjustable foot pedals, which are prone to detaching from the foot during use, and provides a foot pedal with an adjustable spacing that can be adjusted according to usage requirements.

[0005] To achieve the above objectives, the present invention adopts the following technical solution: An adjustable-pitch foot pedal, comprising: Step-on frame; A telescopic pole, wherein the footrest frame is mounted on the telescopic pole and is rotatably connected to the telescopic pole; A locking component, wherein the locking component is mounted on the footrest frame and corresponds to the telescopic bar; The extended frame is installed at both ends of the foot pedal frame, and the extended frame is slidably connected to the foot pedal frame.

[0006] The pedal frame is the main structure connected to the crank connecting rod and is also the main contact surface with the foot. The pedal frame is connected to the crank connecting rod via a telescopic rod. The distance between the pedal frame and the crank connecting rod is adjusted by the telescopic rod. When adjusting the distance between the pedal frame and the pedal frame, a locking component locks one end of the telescopic rod to the pedal frame. Then, the distance is adjusted by rotating the pedal frame, which drives the telescopic rod to rotate. During use, an extended frame can be slid out on the pedal frame to adjust the width, increasing the contact area with the foot and achieving the purpose of adjusting the pedal distance according to usage requirements.

[0007] Preferably, the pedal frame is equipped with a rotating shaft, with both ends of the rotating shaft connected to the two sides of the pedal frame. The pedal frame has a rotating hole that passes through both the pedal frame and the rotating shaft. The telescopic rod includes a connecting rod and a screw. The connecting rod is placed inside the rotating hole, with both ends of the connecting rod located outside the rotating hole. Limiting plates are installed at both ends of the connecting rod. One end of the connecting rod has a threaded hole, and one end of the screw is placed inside the threaded hole and threadedly connected to the connecting rod. The rotating shaft is installed on the pedal frame, and the connecting rod of the telescopic rod passes through the rotating hole on the rotating shaft, allowing the pedal frame to rotate on the connecting rod. Limiting plates are installed at both ends of the connecting rod to restrict the connecting rod to the pedal frame. One end of the screw is inserted into the threaded hole of the connecting rod. The length of the telescopic rod is adjusted by the relative rotation of the connecting rod and the screw. Alternatively, one end of the screw can be unscrewed to disassemble the pedal frame. The other end of the screw is connected to the crank connecting rod. This design allows for adjustment of the distance between the pedal and the crank.

[0008] Preferably, the limiting plate at one end of the connecting rod has several circumferentially distributed fixing slots. The locking assembly includes a fixing rod corresponding to the fixing slots, a sliding block installed on the fixing rod, and a sliding slot installed on the pedal frame. The fixing rod is slidably connected to the pedal frame through the cooperation of the sliding block and the sliding slot. When adjusting the length of the connecting rod by rotating it, it is inconvenient to operate because the connecting rod is placed in the rotating hole. To facilitate operation and rotation, a locking assembly is installed on the pedal frame to lock the connecting rod and the pedal frame together. The fixing rod of the locking assembly is mounted on the side of the pedal frame. The fixing rod slides in the pedal frame through the cooperation of the sliding block and the sliding slot. Sliding the fixing rod slides the fixing rod into the fixing slot of the limiting plate, locking the limiting plate through the fixing rod. At this time, the connecting rod can be rotated together by rotating the pedal frame. This design can lock the connecting rod.

[0009] Preferably, the locking assembly further includes a limiting frame, which is installed on the pedal frame. The limiting frame has a U-shaped cross-section, and the fixing rod is placed inside the limiting frame. The limiting frame opens towards the connecting rod, and a compression plate is installed inside the limiting frame. The compression plate has an arc-shaped cross-section, with one end connected to the limiting frame and the other end abutting the fixing rod. When locking the connecting rod is not required, the position of the fixing rod needs to be limited to prevent it from locking the connecting rod during normal use. Therefore, a limiting frame is installed on the pedal frame, with the fixing rod positioned inside. The limiting frame opens towards the connecting rod to facilitate the fixing rod's movement in and out of the limiting frame. The compression plate, made of elastic material, is then installed inside the limiting frame. The arc-shaped compression plate abuts against the fixing rod, securing it within the limiting frame. Pushing the fixing rod pushes open the compression plates on both sides, allowing it to exit the limiting groove and abut against the limiting plate. This design effectively limits the position of the fixing rod.

[0010] Preferably, a guide plate is installed at the end of the extrusion plate that is in contact with the fixing rod. The guide plate is installed at the end of the extrusion plate facing the connecting rod, and the angle between the guide plate and the extrusion plate is an obtuse angle. When the fixing rod is pushed into the limiting frame, the guide plate can be squeezed open more easily to enter the limiting frame. This design facilitates the entry of the fixing rod into the limiting frame.

[0011] Preferably, the extended frame has a V-shaped cross-section, with limiting holes on both sides of the foot pedal frame and tension rods at both ends. One end of each tension rod is connected to the extended frame, and the other end is positioned within the limiting hole. The extended frame is installed at both ends of the foot pedal frame. The V-shaped extension increases the contact surface of the foot pedal. The extended frame is slidably connected to the foot pedal frame via the tension rods, and the extension length can be adjusted by pulling the tension rods out of the limiting holes. This design allows for adjustment of the length at both ends of the foot pedal frame.

[0012] Preferably, the extended frame is equipped with an adjusting rod. One end of the adjusting rod is connected to the extended frame, and the other end passes through one side of the footrest frame and is placed inside the footrest frame. A rotating nut is installed on the footrest frame, and the rotating nut is rotatably connected to the footrest frame. The rotating nut is threadedly connected to the adjusting rod, and a baffle is installed at the end of the adjusting rod placed inside the footrest frame. The extended frame is equipped with an adjusting rod that passes through one side of the footrest frame. The surface of the adjusting rod is threaded. A rotating nut is installed on the footrest frame, and the adjusting rod passes through and is threadedly connected to the rotating nut. The rotation of the rotating nut pushes the adjusting rod to move. The extended frame can only move horizontally due to the limitation of the tension rods on both sides. Therefore, the rotation of the rotating nut can push the adjusting rod forward, thereby moving the extended frame. The baffle on the adjusting rod limits the movement distance of the adjusting rod. This design facilitates the movement of the extended frame.

[0013] Preferably, an anti-slip pad is installed on the extended frame, and the anti-slip pad corresponds to the extended frame. Installing a V-shaped anti-slip pad on the extended frame improves the anti-slip performance of the foot pedal; this design enhances slip resistance.

[0014] The beneficial effects of this utility model are: the distance between the foot pedals can be adjusted according to the usage requirements, the distance between the foot pedals and the crank can be adjusted, the connecting rod can be locked, the position of the fixing rod can be limited, the fixing rod can be easily put into the limiting frame, the length of both ends of the foot pedal frame can be adjusted, the extension frame can be easily pushed to move, and the anti-slip performance can be improved.

[0019] like Figure 2 , Figure 3 As shown, a rotating shaft 11 is installed on the foot pedal frame 1. The two ends of the rotating shaft 11 are connected to the two sides of the foot pedal frame 1 respectively. The foot pedal frame 1 is provided with a rotating hole 12, which passes through the foot pedal frame 1 and the rotating shaft 11 in sequence. The telescopic rod 2 includes a connecting rod 21 and a screw 22. The connecting rod 21 is placed in the rotating hole 12, and both ends of the connecting rod 21 are located outside the rotating hole 12. Limit plates 23 are installed on both ends of the connecting rod 21. One end of the connecting rod 21 is provided with a threaded hole 24. One end of the screw 22 is placed in the threaded hole 24 and is threadedly connected to the connecting rod 21.

[0020] like Figure 4 As shown, the limiting plate 23 at one end of the connecting rod 21 is provided with a number of circumferentially distributed fixing grooves 25. The locking assembly 3 includes a fixing rod 31, which corresponds to the fixing grooves 25. A sliding block 32 is installed on the fixing rod 31, and a sliding groove 13 is installed on the foot pedal frame 1. The fixing rod 31 is slidably connected to the foot pedal frame 1 through the cooperation of the sliding block 32 and the sliding groove 13.

[0021] The locking assembly 3 also includes a limiting frame 33, which is mounted on the foot pedal frame 1. The limiting frame 33 has a U-shaped cross-section. The fixing rod 31 is placed inside the limiting frame 33. The limiting frame 33 has an opening on the side facing the connecting rod 21. An extrusion piece 34 is installed inside the limiting frame 33. The extrusion piece 34 has an arc-shaped cross-section. One end of the extrusion piece 34 is connected to the limiting frame 33, and the other end of the extrusion piece 34 is attached to the fixing rod 31. A guide piece 35 is installed at the end of the extrusion piece 34 that is attached to the fixing rod 31.

[0022] like Figure 5 As shown, the extended frame 4 has a V-shaped cross-section. Limiting holes 14 are provided on both sides of the stepping frame 1. Tension rods 41 are provided at both ends of the extended frame 4. One end of the tension rod 41 is connected to the extended frame 4, and the other end of the tension rod 41 is placed in the limiting hole 14.

[0023] An adjusting rod 42 is provided on the extended frame 4. One end of the adjusting rod 42 is connected to the extended frame 4, and the other end of the adjusting rod 42 passes through one side of the foot pedal frame 1 and is placed inside the foot pedal frame 1. A rotating nut 43 is installed on the foot pedal frame 1, and the rotating nut 43 is rotatably connected to the foot pedal frame 1. The rotating nut 43 is threadedly connected to the adjusting rod 42. A baffle 44 is installed on the end of the adjusting rod 42 that is placed inside the foot pedal frame 1. An anti-slip pad 45 is installed on the extended frame 4, and the anti-slip pad 45 corresponds to the extended frame 4.

[0024] After installing the pedal, when it needs to be adjusted, move the fixing rod 31 on the pedal frame 1. After the fixing rod 31 pushes open the compression plate 34, it moves out of the limiting frame 33 and into the fixing groove 25. The fixing rod 31 fixes the position of the connecting rod 21. Then, rotate the pedal frame 1 to drive the connecting rod 21 to rotate together. During the rotation of the connecting rod 21, the distance between the pedal and the crank connecting rod is adjusted by screwing out the screw 22 in the threaded hole 24, thus completing the lateral adjustment of the pedal frame 1.

[0025] After the lateral adjustment of the pedal frame 1 is completed, the fixing rod 31 is moved into the limiting frame 33 again and limited by the compression plate 34. Then, the rotating nut 43 is rotated. The extension frame 4 can only move horizontally under the restriction of the tension rods 41 on both sides. Therefore, the rotation of the rotating nut 43 can push the adjusting rod 42 forward, thereby pushing the extension frame 4 to move. The length of the pedal is adjusted by the movement of the extension frame 4 at both ends of the pedal frame 1.
