Detailed Description

The present invention will be further described with reference to the accompanying drawings.

Example 1:

as shown in fig. 1 to 2, an end fixing assembly for an exercise machine spring includes a fixing member 1, a connecting member 2 and an abutting member 3, wherein the fixing member 1 is fixed to the abutting member 3 through the connecting member 2.

The abutting piece 3 is made of a tough polymer plastic, which is a polyamide solid in this embodiment, and the polyamide solid has the following advantages:

1. the hardness is high, and the wear is difficult, and when the exercise apparatus is used, the wear to the abutting part 3 is small, so the service life of the spring is relatively long.

2. The polyamide solid has high toughness, is not easy to generate brittle fracture when the abutting piece 3 is extruded, and has high safety.

3. When the polyamide solid is in friction activity, the surface of the polyamide solid is smooth, and the polyamide solid can be slightly deformed during extrusion so as to reduce noise, improve the environment of equipment in a gymnasium during use and increase the use comfort of an exerciser.

As shown in fig. 1, a movable mechanism 4 is arranged between the abutting part 3 and the connecting part 2, and the movable mechanism 4 comprises a gasket 40 and a limiting protrusion 41; the limiting protrusion 41 is located at the bottom of the connecting piece 2, the connecting piece 2 is rod-shaped, through holes are formed in the middle of the gasket 40 and the abutting piece 3, the gasket 40 is sleeved on the outer surface of the connecting piece 2 and abuts against the limiting protrusion 41, and the abutting piece 3 is sleeved on the outer surface of the connecting piece 2 and abuts against the gasket 40.

The limiting protrusion 41 is mainly used for limiting the gasket 40, so that the gasket 40 is prevented from being separated from the connecting piece 2, the bottom of the abutting piece 3 is supported by the gasket, the contact area between the gasket 40 and the bottom of the abutting piece 3 is increased, and abrasion of the bottom of the abutting piece 3 is avoided (if the abutting piece 3 is directly contacted through the limiting protrusion 41, the abrasion is large).
