Description

Track wheel sled training machine

This creation is about a sports training machine, especially a caterpillar sled training machine.

The sled training machine, also known as the weight training sled, is a new type of weight training equipment developed in recent years. It mainly includes a skateboard. By adding weights such as barbells to the skateboard, the overall weight of the sled training machine is increased. When the user pushes or pulls the skateboard, the skateboard and the ground form relative friction to form resistance, thereby achieving the purpose of weight training. It is used to train the user's muscle explosiveness and is loved by various athletes. However, when pushing or pulling the skateboard, the skateboard and the ground form friction loss, making the sled training machine not suitable for indoor use.

Based on the above-mentioned problems of the sled training machine, the relevant industry has developed a sled training machine with wheels, which mainly adds four rollers to the skateboard. The skateboard moves using the rollers, eliminating the problem of damage caused by the relative contact between the skateboard and the ground, and can be used indoors. The sled training machine with wheels can be further provided with a damping structure for the rollers. When each roller rolls on the ground, the damping effect provided by the damping structure serves as a source of resistance to hinder movement in addition to the counterweight carried by the skateboard. The skateboard is usually provided with a handle in a vertical direction for the user to hold with both hands, so as to facilitate the force to push or pull the sled training machine.

However, in actual use experience, although the weight of the counterweight can be adjusted and the rollers are provided with a damping structure, the grip of the four rollers on the ground is poor. Once encountering a rugged or soft ground, it is easy to cause it to be used smoothly and cannot adapt to various terrains. In addition, the stability of the skateboard is poor when moving forward, and it is easy to rise. In addition, it cannot provide users with a more diverse and rich control experience. As a result, the current sled training machine still has the disadvantage of too monotonous control feeling and lack of changes.

The author of this invention, in view of the above-mentioned shortcomings of the sled training machine, came up with the idea of creating this invention. After much discussion and trial production of samples, as well as many revisions and improvements, this invention was finally launched.

The invention provides a track wheel sled training machine, comprising: a base having a first end and a second end opposite to the first end, an operating member being erected on the first end; a first wheel assembly being arranged at the first end of the base, the first wheel assembly comprising a first wheel axle and two track wheels assembled at both ends of the first wheel axle, each end of the first wheel axle being provided with a coupling portion, the two track wheels respectively comprising a linkage wheel, two driven wheels and a wheel surrounding the first wheel axle; A track of a connecting wheel and the two driven wheels, the connecting wheel is fixedly arranged at the joint of the first wheel shaft, a connecting means is arranged between the track and the connecting wheel, and the connecting wheel and the first wheel shaft can be driven by the operation of the track; and a second wheel set is arranged at the second end of the base, the second wheel set includes a second wheel shaft and two rollers assembled at the two ends of the second wheel shaft, and the two rollers are rotatably arranged on both sides of the second end of the base.

The main purpose of the invented track wheel sled training machine is that it is provided with a first wheel set and a second wheel set, wherein the first wheel set includes a first wheel axle and two track wheels assembled at both ends of the first wheel axle, and the second wheel set includes a second wheel axle and two rollers assembled at both ends of the second wheel axle, so as to increase the grip of the sled training machine, adapt to various different terrains, and improve the stability of the sled training machine when moving.
