Description

Technical Field

[0001] The present application relates to the field of fitness equipment, and in particular to a pedal locking structure and a spinning bike having the same. Background Art

[0002] In the fitness equipment industry, the spinning bike series is a very effective indoor sports equipment. After overcoming all the shortcomings of outdoor riding, the spinning bike makes this sport easy to learn and an aerobic exercise that can exercise the whole body. The spinning bike is basically similar to an ordinary bike, including handrails, seats, pedals and flywheels, and the body is firmly connected as a whole. Unlike ordinary bikes, its structure can be greatly adjusted to make the rider feel more comfortable. The seat cushion designed according to ergonomics provides the greatest comfort, and the two-way pedals and easily adjustable pedal straps meet the needs of users of different levels. Because its scientific design ensures the safety of the participants, and the intensity of the exercise is completely controllable, it is suitable for all people with athletic ability. It mainly promotes cardiovascular exercise, accelerates metabolism, and enhances heart and lung function through long-term and appropriate intensity exercise, thereby improving the body's physique and body shaping. The effect of the spinning bike is mainly reflected on the flywheel. Through the rhythmic exercise with music, it is easier to stick to it, allowing fitness people to effectively strengthen muscle endurance and cardiopulmonary function in a happy exercise. While exercising endurance, it will burn a lot of fat to achieve the purpose of weight loss. It provides users with a smooth and accurate resistance control system, smooth comfort and a continuous "real" cycling experience.

[0003] Existing spinning bikes also have certain defects that need to be overcome by those skilled in the art. For example, the left and right pedals and cranks of existing spinning bikes are locked with threads, but some customers are not professional in assembly and cannot lock them. As a result, the pedals become loose after a period of exercise, and the teeth are damaged when they are used continuously. It is even easy to force the left and right pedals to be locked in the wrong way, which damages the teeth on the cranks and makes them unusable.

[0004] In view of this, those skilled in the art need to improve the pedal locking structure on the spinning bike to overcome the above-mentioned defects. Utility Model Content

[0005] The main purpose of the present application is to provide a pedal locking structure and a spinning bike having the same. Connecting iron sheets are respectively added to the crank and pedal of the existing spinning bike, and then the locking method is adopted with screws and spring washers, so as to avoid the technical problem that the left and right pedals cannot be locked, the left and right pedals are confused and damaged, and the crank teeth cannot be installed and used anymore.

[0028] It should be noted that, in the absence of conflict, the embodiments and features in the embodiments of the present application can be combined with each other. The present application will be described in detail below with reference to the accompanying drawings and in combination with the embodiments.

[0029] like Figure 1 As shown, a pedal locking structure includes a crank assembly 2 fixedly arranged on both sides of a transmission belt pulley 1, and a pedal assembly 3 fixedly arranged at the end of the crank assembly 2, characterized in that a first connecting piece 4 is fixedly arranged at the end of the crank assembly 2, and a second connecting piece 5 matching with the first connecting piece 4 is fixedly arranged on the pedal assembly 3, and the first connecting piece 4 and the second connecting piece 5 are fixedly connected by a plurality of fasteners 8.

[0030] In order to improve stability, the shapes of the first connecting piece 4 and the second connecting piece 5 are first designed. The first connecting piece 4 and the second connecting piece 5 are both triangular. In addition, there are three fasteners 8, which are evenly distributed on a circle with the axis of the pedal assembly 3 as the center. Therefore, the three corners of the first connecting piece 4 and the second connecting piece 5 correspond to fasteners 8. By utilizing the stability of the triangle, the first connecting piece 4 and the second connecting piece 5 are more stable after being connected. During the use of the spinning bike, the user needs to continuously step on the pedal assembly 3. Since the original pedal assembly 3 is threadedly locked by the teeth on the pedal assembly 3, it is very easy to loosen after a certain period of exercise. The above-mentioned locking structure is adopted, so that the three fasteners 8 are distributed around the axis of the pedal assembly 3, thereby deviating from its axis. Therefore, not only the connection stability is strong, but also the pedal assembly 3 is not easy to loosen during use.

[0031] In this embodiment, preferably, the first connecting piece 4 and the second connecting piece 5 are made of metal. To facilitate processing, the first connecting piece 4 is welded and fixed to the crank assembly 2 , and the second connecting piece 5 is welded and fixed to the pedal assembly 3 .

[0032] In this embodiment, preferably, the fastener 8 is a screw, and a threaded hole matching the screw is provided on the first connecting plate 4 and / or the second connecting plate 5. The fastener 8 is also provided with a spring washer 9. The spring washer 9 can prevent the screw from loosening during the movement of the spinning bike.

[0033] Preferably, in this embodiment, a central axis welding assembly 6 is coaxially fixedly disposed on the driving belt pulley 1 , and the crank assemblies 2 on both sides are fixedly connected to the central axis welding assembly 6 , respectively.

[0034] In this embodiment, preferably, crank decorative covers 7 are also provided on the crank assemblies 2 on both sides.

[0035] In order to facilitate the fixing of the user's feet to the pedal assembly 3 , a pedal strap 10 is further provided on the pedal assembly 3 .

[0036] like Figure 2-Figure 4 As shown, the present application provides a spinning bike, comprising a bike frame 11, and a pedal assembly disposed on the bike frame 11, wherein the pedal assembly comprises a drive pulley 1 rotatably disposed on the bike frame 11, and the above-mentioned pedal locking structure.

[0037] The above description is only the preferred embodiment of the present application and is not intended to limit the present application. For those skilled in the art, the present application may have various modifications and variations. Any modification, equivalent replacement, improvement, etc. made within the spirit and principle of the present application shall be included in the protection scope of the present application.
