Pedal convenient to disassemble

Abstract

The utility model relates to the technical field of pedals, in particular to a pedal convenient to disassemble. The device comprises a transmission assembly, and pedal fixing assemblies are arranged on the two sides of the transmission assembly. Due to the design of the double nuts, the square conical block can be easily withdrawn from the square groove only by screwing off the small nut to relieve limiting and then screwing the large nut and utilizing the jacking force generated by axial movement of the large nut during disassembly, and due to the design, a knocking tool is not needed, so that the risk that the pedal and equipment are damaged due to knocking is avoided, and the service life of the pedal is prolonged. Meanwhile, on products with narrow inner side spaces of the pedals such as exercise bikes and mini-cars, quick disassembly can be achieved, the disassembly efficiency of the pedals is greatly improved, and daily maintenance, repair, transportation and packaging work of the products are facilitated.

Description

Technical Field

[0001] This utility model relates to the field of pedal technology, and in particular to a pedal that is easy to disassemble. Background Technology

[0002] In the field of exercise equipment such as stationary bikes, mini bikes, and rehabilitation mini bikes, the pedals, as core power transmission components, directly affect the user experience and ease of maintenance through their connection structure design. Currently, the mainstream pedal connection technology on the market adopts a conical fit structure, which involves an interference fit between a square conical connector and a square conical hole on the connecting rod, secured with a nut to achieve a stable connection. This structure is widely used in the industry due to its advantages of being suitable for both left and right feet and preventing loosening after installation.

[0003] However, this conical fit structure has a significant drawback: because the square conical connector and the square conical hole rely on a large interference fit for a stable connection, a large external force is required for disassembly. In practice, tools such as hammers are usually needed to strike the foot pedal to force the square conical connector out of the conical hole.

[0004] More notably, some exercise bikes and mini bikes have large outer shells or protective components on the inside of the pedals to optimize space or strengthen structural strength. This structure severely restricts disassembly space, making it difficult for hammering tools to find a foothold, or even impossible to disassemble by hammering. For example, some compact rehabilitation exercise mini bikes have the inside of the pedals tightly attached to the drive mechanism shell, making it impossible to disassemble the pedals without removing other core components. This difficulty in disassembly not only greatly inconveniences daily maintenance and repair but also hinders product transportation and packaging—non-removable pedals significantly increase packaging volume, raise transportation costs, and increase the risk of pedal damage during transport. Utility Model Content

[0005] The purpose of this invention is to provide a foot pedal that is easy to disassemble, so as to solve the problems mentioned in the background art.

[0006] To achieve the above objectives, the present invention provides the following technical solution, which includes a transmission assembly, wherein foot pedal fixing assemblies are provided on both sides of the transmission assembly.

[0007] In a preferred embodiment of this utility model, the transmission assembly includes a drive disk, with L-shaped transmission rods on both sides of the drive disk, and a mounting component on the top of the L-shaped transmission rods, the mounting component having a square groove.

[0008] As a preferred embodiment of this utility model, the foot pedal fixing assembly includes a pedal fixing rod, a stud is provided at the top end of the pedal fixing rod, a fixing block one is provided at the tail end of the pedal fixing rod, a square pyramidal block is provided on the back of the fixing block one, a fixing block two is provided on the back of the square pyramidal block, a reverse thread is provided on the outer wall of the fixing block one, and a forward thread is provided on the outer wall of the fixing block two.

[0009] In a preferred embodiment of this utility model, the square pyramidal block is inserted into a square groove.

[0010] As a preferred embodiment of this utility model, a large nut is threaded on the first fixing block and a small nut is threaded on the second fixing block, and the foot pedal fixing assembly is fixed to the mounting component by the small nut.

[0011] Compared with the prior art, the above-mentioned technical solution of this utility model has the following beneficial technical effects:

[0012] 1. This utility model uses a double-nut design. During disassembly, you only need to unscrew the small nut to release the limit, and then turn the large nut. The axial movement of the large nut generates a pushing force, which can easily remove the square cone block from the square groove. This design eliminates the need for hammering tools, avoiding the risk of damage to the pedals and equipment caused by hammering. At the same time, it can also achieve quick disassembly on products with limited space inside the pedals, such as exercise bikes and mini bikes. This greatly improves the disassembly efficiency of the pedals and facilitates the daily maintenance, repair and transportation packaging of the product.

[0013] 2. Traditional threaded pedals have left and right sides, and incorrect installation can easily damage the threads and prevent installation. However, this utility model adopts a matching structure of square groove and square cone block, which can achieve precise fit no matter which direction it is inserted from. This eliminates the restriction on the installation direction, reduces the difficulty of installation operation, avoids the problem of component damage caused by incorrect installation, and improves the user's installation experience and assembly efficiency.

[0014] 3. This utility model solves the problems of difficult disassembly and limited installation. It is applicable to a variety of products such as exercise bikes, mini bikes, and rehabilitation exercise mini bikes. Whether for daily fitness, leisure cycling or rehabilitation training, it can meet users' needs for convenient installation and disassembly of pedals. Attached Figure Description

Detailed Implementation

[0020] To make the objectives, technical solutions, and advantages of this utility model clearer, the present utility model will be further described in detail below with reference to specific embodiments and accompanying drawings. It should be understood that these descriptions are merely exemplary and not intended to limit the scope of this utility model. Furthermore, descriptions of well-known structures and technologies are omitted in the following description to avoid unnecessarily obscuring the concept of this utility model.

[0021] like Figure 1-4 As shown, the present invention proposes a foot pedal that is easy to disassemble. It mainly consists of a transmission assembly 1 and a foot pedal fixing assembly 2, and its specific connection structure is as follows:

[0022] The transmission component 1, as the core transmission component of the overall structure, consists of a drive disc 10 and L-shaped transmission rods 11 on both sides. The drive disc 10 serves as the power output end and can be connected to an external mechanism to transmit power. The L-shaped transmission rods 11 are symmetrically arranged on both sides of the drive disc 10. An installation component 12 is fixedly installed on the top of the L-shaped transmission rod 11. The surface of the installation component 12 is provided with a square groove 13 that is compatible with the pedal fixing component 2. The size and shape of the square groove 13 match the square pyramid block 25 in the pedal fixing component 2, providing a positioning base and connection interface for the installation of the pedal fixing component 2.

[0023] The pedal fixing assembly 2 includes a pedal fixing rod 20, which serves as the main body of the pedal fixing assembly 2. A stud 26 is provided at the top end for limiting the pedal position. The tail end is connected in sequence to fixing block 1 21, square cone block 25, and fixing block 23 to form a complete connection structure. Fixing block 1 21 has a reverse thread 22 on its outer wall, which is used in conjunction with the large nut 3. Fixing block 23 has a forward thread 24 on its outer wall, which is used in conjunction with the small nut 4. Through the thread design with different directions of rotation, the nuts can be effectively prevented from loosening due to vibration and other factors during use. The square cone block 25 serves as the connection hub between the transmission assembly 1 and the pedal fixing assembly 2. Its shape is adapted to the square groove 13 on the mounting part 12. During installation, the square cone block 25 can be tightly inserted into the square groove 13. The fit between the cone surface and the groove wall forms a stable mechanical connection, ensuring that the pedal can stably transmit power during use.

[0024] When disassembling the pedal, first use a wrench of appropriate size to rotate the small nut 4 on the pedal structure counterclockwise to remove it. The small nut 4 mainly serves as a pre-fix and limiter. By removing it, the axial constraint on the large nut 3 and internal components can be released, providing operating space for the subsequent rotation of the large nut 3.

[0025] After the small nut 4 is disassembled, use the matching special wrench or tool to turn the large nut 3 clockwise. Under the transmission action of the threaded structure, the large nut 3 moves outward along the axis. When the large nut 3 moves outward, it abuts against the mounting part 12. Under the pushing force of the large nut 3, the square cone block 25 is displaced along the axial direction of the square groove 13 and gradually exits from the square groove 13. The square cone block 25 and the square groove 13 adopt an interference fit initial installation method. The pushing force generated by the large nut 3 can effectively overcome the fit resistance between the two, so that the square cone block 25 can be smoothly separated from the square groove 13, thereby completing the disassembly process of the pedal and achieving the purpose of convenient and quick disassembly.

[0026] It should be understood that the specific embodiments described above are merely illustrative or explanatory of the principles of this utility model and do not constitute a limitation thereof. Therefore, any modifications, equivalent substitutions, improvements, etc., made without departing from the spirit and scope of this utility model should be included within its protection scope. Furthermore, the appended claims are intended to cover all variations and modifications falling within the scope and boundaries of the appended claims, or equivalent forms of such scope and boundaries.
