Abstract
The utility model discloses an oil cylinder device of exercising machine used for exercising bodies. The upper part of the cylinder is provided with a connecting ring, the connecting ring is provided with a connecting hole, the connecting hole is matched with an oil passing pipeline and the connecting hole is rotated relatively to the oil passing pipeline, the oil cylinder is communicated with the oil passing pipeline by the annular groove in the connecting hole, the other end of the oil passing pipeline is communicated with one end of a control switch, the other end of the control switch is connected with the other oil passing pipeline and the oil cylinder, and the piston rods of the two oil cylinders are separately connected with the left pedal and the right pedal. The power of exercising body can be adjusted by adjusting the control switch. The utility model solves the problem of oil leakage. The utility model has the advantages of smooth action in exercising, and simple structure.
Description
The utility model relates to the body exercising machine cylinder apparatus that a kind of health of exercising is used.
Used body exercising machine, when trampling motion, oil cylinder is along with moving reciprocatingly, so need dispose flexible pipe, but frequent motion easily makes the flexible pipe leakage of oil, also influences the smooth and easy of trample action and carries out, even can't use, and seriously influences the sale of product.
The purpose of this utility model is to design a kind of cylinder body top and be provided with connecting hole for overcoming above-mentioned deficiency; This hole and the cylinder apparatus that oil pipe road, cylinder body are connected have replaced flexible pipe, have overcome a leakage of oil difficult problem, and can make trample the motion smooth and easy carrying out.
The utility model content, the body exercising machine cylinder apparatus is to now using the improvement of equipment, the connecting ring on cylinder body top is provided with and the relatively turnable connecting hole in oil pipe road, done annular recess in the connecting hole, annular recess is communicated with inner chamber of cylinder block through the hole, piston and piston rod are installed in the cylinder body, the radial hole that the oil pipe road is provided with axial hole and communicates with it, axial hole one end (outer end) in oil pipe road does not drill through, the other end in oil pipe road is connected with gauge tap through screw thread, in the radial hole both sides in oil pipe road sealing ring is housed; The elastic collar that limits its axial location is housed in the two ends of connecting ring.
The utility model advantage, the connecting hole passing hole channel on the cylinder body top of enhancing body resistance Oil cylinder device is communicated with cylinder body oil pocket and oil pipe road, has replaced used flexible pipe, has overcome the shortcoming that is easy to generate leakage of oil; Trample action can smooth and easyly carry out unimpededly during the exercise health, has saved flexible pipe, uses reliable.
Description of drawings
