Height-adjustable horizontal force output equipment

Abstract

The invention discloses height-adjustable horizontal force output equipment which comprises a moving seat, a U-shaped plate is mounted on the moving seat, a rectangular frame is slidably connected into the U-shaped plate, a servo motor is mounted at the bottom of the moving seat, a driving gear is mounted at the output end of the servo motor, two threaded cylinders are rotatably connected to the upper end of the moving seat, and a driving gear is mounted at the output end of the driving gear. A transmission mechanism is arranged between the two threaded cylinders, screw rods are in threaded connection with the interiors of the two threaded cylinders, the upper ends of the two screw rods are fixedly connected with the bottom of the rectangular frame, and a driven gear is fixedly installed outside one of the threaded cylinders. Through cooperation of the limiting wheel and the warning lamp, a load-bearing cable can be subjected to horizontal detection, through cooperation of the servo motor, the threaded cylinder and the screw rod, the load-bearing cable can be subjected to horizontal adjustment, so that the longitudinal force of the balance weight can be changed into horizontal force, and the tray and the balance weight can be shielded and prevented from falling off and being damaged; and an experimenter can be protected.

Description

Technical field [0001] The present invention relates to a horizontal force output BACKGROUND laboratory equipment, in particular, to a height adjustable horizontal force output device. Background technique [0002] When the human body sitting on the bench and stand up straight, waist and abdominal muscles play a very important role in the next, but due to the difference each person's muscle density, lower back and abdominal muscles are also different. [0003] Therefore, if the individual waist and abdomen muscle strength testing, the need to provide security, such as the protection of laboratory personnel, laboratory equipment to be protected; currently, the human waist and abdominal muscles for measuring equipment more, a lot of fitness equipment can be realize, however, is difficult to achieve accurate measurements of the waist and abdominal muscles at different heights in the horizontal direction. Inventive content [0004] Object of the present invention is to solve the dra...

AI Technical Summary

Problems solved by technology

[0003] Therefore, when testing personal waist and abdomen muscle strength, it is necessary to provide safety guarantees, such as the protection of experimenters and the protection of experimental equipment; at present, there are many measurement equipment for human waist and abdominal muscles, and many fitness equipment can Achieving, however, it is difficult to achieve accurate measurements of lumbar and abdominal muscle strength at different height levels
