Detailed Description

As shown in fig. 1, 2, 3 and 4, the strength training exercise machine without the weight plate structure comprises a main frame, wherein the main frame comprises a base 15 and an upright post 16, and a movement assembly is arranged on the main frame and can swing relative to the main frame in the use process.

The motion assembly comprises a support assembly 19, a seat cushion 18, a backrest 13, a handle 1, a thrust adjusting structure and a lever assembly.

The two groups of handles 1 are respectively arranged on two sides of the supporting component 19, and the lower end of the handle 1 is respectively provided with a group of thrust adjusting structures.

Thrust adjust the structure include arc arm 2, slip regulating block 5, connecting rod 8, bolt 5, the upper end and the slip regulating block 5 of connecting rod 8 are connected, the other end and the lever subassembly of connecting rod 8 are connected, arc arm 2 on be equipped with arc swing arm spout 3, slip regulating block 4 can slide in arc swing arm spout 3, arc arm 2 is gone up and is equipped with regulation hole 20 along the arc outside, bolt 5 inserts regulation hole 20 and can fix arc arm 2 and slip regulating block 4 relative position, the lower extreme of arc arm 2 is articulated through the lower part supporting seat of first articulated shaft 17 with supporting component 19.

The lever assembly comprises a lever support 11, a main lever 9 and a rotating shaft 7, wherein two ends of the rotating shaft 7 are respectively connected with the end parts of the connecting rods 8 on the same side through pull rods 6, one end of the main lever 9 is connected with the middle part of the rotating shaft 7, the other end of the main lever 9 is hinged with the lever support 11, the middle part of the main lever 9 is connected with the support assembly through a second hinge shaft 10, and the other end of the lever support 11 is hinged with an upright post 16 through a third hinge shaft 12.
