Problems solved by technology

[0006] However, the general fixed pulley block system directly fixes the pulley seat on the frame of the sports equipment, and the pulley block and the sports equipment are rigidly connected, so the vibration on the sports equipment and the vibration generated by the pulley block will be transmitted to each other to generate Interference, ranging from affecting the progress of training actions, causing resonance and causing damage to sports equipment
[0007] The movable pulley block is temporarily hung on the frame of the sports equipment, and the combination with the sports equipment is not tight, and it is easy to cause collisions between parts during use. First, the collision will easily cause friction wear of the parts. The noise generated by the collision can also affect the mood of the user
When the vibration is too large, it may cause the movable pulley block to fall off and cause injury to the user

Embodiment Construction

[0036] see figure 1 , is a schematic diagram of an embodiment of the present invention. As shown in the figure, the pulley assembly 20 of the present invention can be disposed on a sports equipment 10 . Generally speaking, the sports equipment 10 usually has a frame 12 for setting various components of the sports equipment 10 . The sports equipment 10 of the present invention can be provided with at least one joint portion 14 at an appropriate position of the frame 12 to fix the pulley assembly 20 of the present invention (for example, it can be combined and fixed with the adjustment tube 24 of the pulley block 20, and can cooperate with the adjustment hole 243 and The structure of the positioning pin 141 can adjust the position). Wherein, the sports equipment described in the present invention includes but not limited to general sports equipment and Pilates equipment.

[0037] see Figure 2 to Figure 4A , Figure 4B , are respectively a perspective view, a perspective ex...

Abstract

The invention relates to a pulley assembly, in particular to the pulley assembly applicable to sports apparatuses. The pulley assembly can be arranged on a frame of a sports apparatus and have a pulley module and a buffering module. The buffering module utilizes a hook in a question mark shape to be connected with the sports apparatus, a U-shaped ring and the annular part of the hook in the question mark shape can form a movable joint structure, the other end of the U-shaped ring is connected with the pulley module, and a spring sleeves the outer sides of the hook in the question mark shape and the U-shaped ring to push the pulley module and the frame of the sports apparatus. By utilizing the pulley module, the vibration transmission between the pulley module and the sports apparatus can be effectively obstructed, and the noises generated from the impact among parts and components can be reduced.

Description

technical field [0001] The invention relates to a pulley assembly, in particular to a pulley assembly suitable for sports equipment. Background technique [0002] With the improvement of the quality of life of the people, people pay more and more attention to health preservation and physical health. Therefore, exercise and fitness have gradually become a trend in recent years. [0003] Although outdoor sports are beneficial to physical and mental health, they are too limited by weather factors, such as heavy wind and heavy rain, which are not conducive to outdoor sports. Moreover, the situation of air pollution has become more and more serious in recent years, and it is often heard that the smog is shrouded and the content of PM2.5 particles in the air exceeds the standard. If you carry out outdoor activities in the presence of air pollution, your physical and mental state may not be improved, but you may be harmed by air pollution first. [0004] In order to reduce the ma...
