Description

Technical Field

[0001] The utility model relates to the technical field of bicycle spare parts, in particular to a dual-purpose adjustable magnetic lock pedal. Background Art

[0002] Cycling has become a popular way of transportation and fitness exercise. As a basic component of a bicycle, a lock pedal transmits human power from the rider's foot to the rear wheel of the bicycle, thereby driving the bicycle forward. Currently, cycling is divided into non-locked cycling and locked cycling. During non-locked cycling, there is no fixed connection between the pedal and the cycling shoe, and the pedal is in a flat plate shape. The cycling shoe can leave the pedal freely at any time. This type of pedal is also called a flat pedal and is the most common cycling method. Additionally, during locked cycling, the rider uses the lock pedal and the cycling shoe in combination. Not only can the rider step down on the bicycle lock pedal, but also apply an upward pulling force to the lock pedal by pulling up with the foot, realizing the full process of power generation during bicycle pedaling, that is, the so-called locked cycling state. Currently, there are two types of lock pedals. One is a mechanical lock pedal, which is connected by a mechanical structure. The other is a magnetic lock pedal, where the magnet is installed on the lock pedal and the lock piece is installed at the bottom of the cycling shoe. The magnetic lock pedal and the lock piece are connected by the magnetic force of the magnet. When unlocking, an external force is applied by the foot. When the external force exceeds the magnetic force of the magnet, the lock pedal and the cycling shoe are separated, and thus the unlocking is successful. Because there is a height difference between the installation surface of the lock piece on the bottom of the cycling shoe and the bottom surface of the shoe, and the height differences of different styles of cycling shoes are different, and the height difference will also change with the wear of the sole. However, the relative positions of the magnet and the pedaling surface of the existing magnetic lock pedal are fixed, and the height of the magnet cannot be adjusted. This results in a situation where the distance between the magnet and the lock piece installed at the bottom of the cycling shoe is often too far or too close. When the distance is too far, the suction is insufficient, and there is a risk of accidental unlocking. When the distance is too close, there is not enough pre-tightening force between the pedaling surface and the bottom surface of the cycling shoe, and the connection between the shoe and the pedal is too loose, resulting in relative shaking during cycling, making the rider feel uncomfortable and unable to efficiently transmit the pedaling force. Additionally, the magnet of the existing magnetic lock pedal is supported at the bottom by materials such as rubber and silicone, and the magnet protrudes from the pedaling surface. When the rider rides with ordinary flat shoes, due to the limited elastic deformation of rubber, silicone, etc., the magnet cannot be completely pressed into the lock pedal, resulting in an uneven pedaling surface and unstable pedaling. This makes it impossible for the rider to use the existing magnetic lock pedal normally when wearing ordinary flat shoes during non-locked cycling. Summary of the Utility Model

[0003] In view of the above problems, the utility model adopts the following technical solutions:

[0004] A dual-purpose adjustable magnetic lock pedal includes a magnet, a threaded rod, a spring, a lock pedal body, a shaft rod, a bushing, a locknut, etc. The lock pedal body has one or two magnet mounting holes.

[0005] Furthermore, the magnet consists of a magnetic-conducting outer shell and a magnetic inner core. The number of magnets installed can be one or two. If the number of installed magnets is two, the sizes of the two magnets can be the same or different.

[0006] Furthermore, the pedal body can be single-sided or double-sided, that is, the pedal body has one or two pedal surfaces. The pedal surface refers to the plane where the sole of the shoe contacts the pedal, that is, the plane where the pedal receives the pedaling force transmitted by the rider through the sole of the shoe.

[0007] Furthermore, the magnet mounting holes are provided on the pedal body. The number of magnet mounting holes can be one or two. If the number of magnet mounting holes is one, the magnet mounting hole is provided on the pedal surface on one side of the shaft rod; if the number of magnet mounting holes is two, the two magnet mounting holes are respectively provided on both sides of the shaft rod, and the two magnet mounting holes can be arranged on the same pedal surface of the pedal body or on different pedal surfaces.

[0008] Furthermore, the magnet is connected to the threaded rod, and the threaded rod passes through the magnet mounting hole and is connected to the locknut.

[0009] Furthermore, the spring is placed between the magnet and the pedal body, and the threaded rod passes through the spring.

[0010] Furthermore, the bushing is placed between the pedal body and the locknut. The bushing is made of metal material and is in a circular tubular shape. One end of the bushing is inserted into the magnet mounting hole, and there is a flange at the end of the bushing close to the locknut. The flange can prevent the bushing from completely passing through the magnet mounting hole, and the threaded rod passes through the bushing and is connected to the locknut.

[0011] Compared with the prior art, the beneficial effects of the present utility model are as follows: By means of the locknut, the relative height between the magnet and the pedal surface of the pedal body can be adjusted, so as to adapt to different sole structures, adjust the distance between the magnet and the sole lock piece to the optimal state, avoid the situation that the cycling shoes and the pedal are too loose or too tight, and better meet the use requirements of the rider; In addition, the magnet is supported by the spring at the bottom. When the rider rides with ordinary flat shoes, due to the compression of the spring, the magnet can be completely pressed into the pedal body, so the pedal surface is flat and the pedaling is firm. This enables the bicycle equipped with the present utility model to be normally pedaled when the rider rides without locking, meeting the dual requirements of the rider for locked and unlocked riding.

In addition, the terms "first" and "second" are used for descriptive purposes only and cannot be understood as indicating or implying relative importance.

[0019] In the description of the present utility model, it should be noted that, unless otherwise clearly specified and limited, the term "

[0020] The terms "installed", "provided with", "connected", etc. should be understood in a broad sense. For example, "connected" can be a fixed connection, a detachable connection, or an integral connection; it can be directly connected, or indirectly connected through an intermediate medium, or it can be the internal communication of two elements. For ordinary technicians in this field, the specific meanings of the above terms in the present utility model can be understood according to specific circumstances.

[0021] like Figures 1 to 4As shown, the embodiment of the present utility model relates to a dual-purpose adjustable magnetic lock pedal, which comprises a magnet 1, a threaded rod 2, a spring 3, a pedal body 4, a shaft rod 5, a bushing 7, a locknut 8, etc.

[0022] Furthermore, the pedal body 4 can be used for single-sided stepping or double-sided stepping. As Figure 3 shown, the first stepping surface 11 and the second stepping surface 12 are both rideable stepping surfaces.

[0023] Furthermore, the magnet mounting hole 6 is provided on the pedal body 4. The number of the magnet mounting holes 6 can be one or two. If the number of the magnet mounting holes 6 is one, the magnet mounting hole 6 is provided on the second stepping surface 12 on one side of the shaft rod 5; if the number of the magnet mounting holes 6 is two, the two magnet mounting holes 6 are respectively provided on both sides of the shaft rod 5, and the two magnet mounting holes 6 can be respectively arranged on the first stepping surface 11 and the second stepping surface 12 (as Figure 3 shown); they can also be arranged on the second stepping surface 12 at the same time (as Figure 4 shown).

[0024] Furthermore, the magnet 1 is composed of a magnetic conduction outer shell 9 and a magnetic inner core 10. The magnetic attraction force is gathered to the upper surface of the magnet 1 through the magnetic conduction outer shell 9, so as to increase the magnetic attraction force of the magnet 1.

[0025] Furthermore, the number of the installed magnets 1 can be one or two. If the number of the installed magnets 1 is two, the sizes of the two magnets 1 can be the same or different. Figure 2 is the case of installing one magnet 1. Figure 3 and Figure 4 is the case of installing two magnets 1.

[0026] Furthermore, when installing two magnets 1, there are also non-coplanar installation and coplanar installation. Figure 3 is the case of non-coplanar installation of the two magnets 1. Figure 4 is the case of coplanar installation of the two magnets 1.

[0027] Furthermore, if there is one magnet 1 installed (as Figure 2 shown), then the first stepping surface 11 is the stepping surface with magnetic attraction force, and the magnetic attraction force is the suction force of a single magnet 1. The second stepping surface 12 can be used as a flat pedal; if there are two magnets 1 installed, that is, when the two magnets 1 are non-coplanarly installed (as Figure 3As shown, both the first stepping surface 11 and the second stepping surface 12 are stepping surfaces with magnetic attraction, and the magnetic attraction is the attraction of a single magnet 1; if two magnets 1 are installed and the two magnets 1 are installed on the same surface (such as Figure 4 As shown), the first stepping surface 11 is a stepping surface with magnetic attraction, and the magnetic attraction is the resultant force of the attractions of the two magnets 1, and the second stepping surface 12 can be used for flat stepping.

[0028] Further, the magnet 1 is connected to the threaded rod 2, and the threaded rod 2 passes through the magnet mounting hole 6.

[0029] Further, a spring 3 is placed between the magnet 1 and the pedal body 4. The magnet 1 can be kept in the lifted state under the support of the spring 3, and at the same time, when the magnet 1 is subjected to a downward pressure, it can also retract into the pedal body 4.

[0030] Further, when the magnet 1 is subjected to a lateral pulling force, the magnet 1 tilts in the direction of the lateral pulling force under the support of the spring 3. When the lateral pulling force disappears, under the supporting force of the spring 3, the magnet 1 will return to its original position, that is, above the magnet mounting hole 6.

[0031] Further, a bushing 7 is placed between the pedal body 4 and the locknut 8. The bushing 7 is made of a metal material. The structure of the bushing 7 is a circular tube. One end of the bushing 7 is inserted into the magnet mounting hole 6. There is a flange at one end of the bushing 7 close to the locknut 8. The flange can prevent the bushing 7 from completely passing through the magnet mounting hole 6. The threaded rod 2 passes through the bushing 7 and is connected to the locknut 8.

[0032] Further, the locknut 8 can effectively prevent loosening caused by vibrations generated during the cycling pedaling process. By rotating the locknut 8, the length of the upper end of the threaded rod 2 extending out of the mounting hole 6 can be changed. Since the upper end of the threaded rod 2 is connected to the magnet 1, the height difference between the magnet 1 and the first stepping surface 11 is thus changed.

[0033] With the anti-loosening nut 8 of the present utility model, the height of the magnet 1 exposed from the first stepping surface 11 can be adjusted, so that the distance between the magnet 1 and the sole locking piece can be adjusted to the optimal ideal state, thus adapting to different sole structures and achieving the best suction effect. Supported by the spring 3, the magnet 1 can move flexibly in multiple degrees of freedom, thus reducing the probability of accidental unlocking during cycling and increasing the use safety of the magnetic lock pedal. In addition, when cycling with ordinary flat shoes, the spring 3 will be compressed, and at the same time, the magnet 1 will be pressed into the pedal body 4, and the present utility model can be used normally like an ordinary flat pedal.

[0034] The present utility model has been described by the above related embodiments. However, the above embodiments are only examples for implementing the present utility model. It must be pointed out that the disclosed embodiments do not limit the scope of the present utility model. On the contrary, modifications and refinements made without departing from the spirit and scope of the present utility model fall within the scope of the patent protection of the present utility model.
