Background technique:

With the vigorous promotion of the national fitness campaign, people pay more and more attention to fitness and physical exercise. At present, urban and rural communities are equipped with many types of public fitness equipment, which are welcomed and loved by the general public. As a fitness equipment for exercising the lumbar muscles and lumbar spine mobility, the waist twister is also one of the common public fitness equipment.

There are many types of waist twisters. A common waist twister is that a plurality of handrails are welded on the upper side wall of a column, and three pedal rotating discs are fixed on the ground around the column. Each pedal rotating disc Corresponds to a handrail. When in use, people step on the pedal rotating disk with their feet, hold the handrail firmly with their hands, and realize the purpose of exercising the lumbar muscles and lumbar spine mobility by rotating the waist. However, the ground setting height of the column on this waist twister is generally 1.6-1.7 meters, which is only suitable for ordinary adults to use. For people who are not tall enough, the handrails generally cannot be grasped and cannot meet different uses. need.

Invention content:

The purpose of the present invention is to overcome the deficiencies of the prior art and provide a double-person waist twister that can be adjusted up and down. An upper pedal disc is installed on the board, and the upper pedal disc can increase the friction force of the user, has an anti-slip effect, and can protect the pedals from damage at the same time.

The scheme that the present invention solves described technical problem is:

An up and down adjustable waist twister for two persons, comprising a cylinder, one side of the cylinder is provided with a vertical screw, and the two ends of the vertical screw are hinged on the connecting blocks fixed on the upper and middle parts of the cylinder, vertically The lower end of the straight screw protrudes downwards from the connecting block and is fixed with a rotating disk. The adjusting sleeve is inserted into the cylinder, and the inner wall of the adjusting sleeve is fixed with a self-lubricating wear-resistant layer, which is pressed against the cylinder. on the outer wall;

The bottom surface of the left and right sides of the column is fixed with a waist support seat, the middle part of the top surface of the waist support seat is hinged with a rotating column, the top of the rotating column is fixed with a pedal, and the outer walls of the left and right sides of the adjustment sleeve are fixed. There is a handle, which corresponds to the pedal.

The handle part is a U-shaped elbow, the two ends of the handle part are welded and fixed on the side plate body, the middle part of the side plate body is formed with a raised part, and the raised part is fixedly connected to the outer wall of the adjustment sleeve by bolts .

The pedal is a circular plate body, and a plurality of stepped through holes are formed on the pedal. The middle part of the bottom surface of the upper pedal plate made of rubber has a mounting groove, and the pedal is nested in the mounting groove. The top surface of the groove is formed with a plurality of inserting rods, and the bottom end of the inserting rods passes through the corresponding stepped through holes and is inserted into the central hole of the permanent magnet block fixed on the bottom surface of the pedal. The bottom end is adsorbed with the permanent magnet block.

The outer wall of the curved section of the handle is covered with a rubber protection layer.

The insertion rod is a stepped rod corresponding to the stepped through hole.

The outstanding effect of the present invention is: compared with the prior art, its hand-held part can be adjusted up and down according to needs, so as to meet the requirements of users of different heights. The pedal plate can increase the user's frictional force and has an anti-slip effect, and at the same time, can protect the pedals from being damaged.

detailed description:

Embodiment, see as shown in Fig. 1 to 4, a kind of up and down adjustable waist twister for two people, comprises cylinder 10, and one side of described cylinder 10 is provided with vertical screw rod 11, and the two ends of vertical screw rod 11 Hinged on the upper and middle part of the cylinder 10 fixed on the connecting block 12, the lower end of the vertical screw 11 protrudes downwards from the connecting block 12 and is fixed with a rotating disk 111, the adjusting sleeve 13 is inserted in the cylinder 10, the adjusting sleeve A self-lubricating wear-resistant layer 131 is fixed on the inner wall of 13, and the self-lubricating wear-resistant layer 131 is pressed against the outer wall of the cylinder 10;

The bottom surface of the left and right sides of the column 10 is fixed with a waist-twisting support seat 14, the middle part of the top surface of the waist-twisting support seat 14 is hinged with a rotating column 15, and the top of the rotating column 15 is fixed with a pedal 16, and an adjustment sleeve 13 Handholds 17 are fixed on the outer walls of the left and right sides, and the handholds 17 correspond to the pedals 16.

Furthermore, the handle part 17 is a U-shaped elbow, and the two ends of the handle part 17 are welded and fixed on the side plate body 171. The middle part of the side plate body 171 is formed with a raised part 172, and the raised part 172 passes through Bolts are fixedly connected on the outer side wall of the adjustment sleeve 13 .
