Abstract
The utility model relates to an improved expander for shoulders and arms. The utility model comprises a pull rope, a handle and a pull rope rolling and supporting device. The pull rope rolling and supporting device is composed of a base board, a pulley wheel supporting shaft, a pulley wheel, a rolling bearing and a fixing nut, wherein one end of the pulley wheel supporting shaft is provided with a shoulder spacer and is fixedly arranged on one side surface of the base board, and the other end of the pulley wheel supporting shaft is provided with outer screw threads and is a free end; the pulley wheel is fixedly sheathed on an outer ring of the rolling bearing; an inner ring of the rolling bearing is movably sheathed on the pulley wheel supporting shaft; the inner ring of the rolling bearing is connected with the shoulder spacer of the pulley wheel supporting shaft which is fixedly impacted to a fixing nut on the free end of the pulley wheel supporting shaft by screw threads; base board fixing holes which run through the base board are dispersedly arranged on the base board. When the utility model is arranged, steel nails are used to fix the base board to a wall surface which is above a door frame through the base board fixing holes, and then the pulley wheel is arranged on the pulley wheel supporting shaft, and finally the pull rope is sheathed on the pulley wheel. The utility model has the characteristics of small size, easy indoor installation and use and low noise.
Description
Technical field: the utility model relates to a kind of improved body-building apparatus, is meant a kind of improved shoulder arm stretcher especially.
Background technology: shoulder arm stretcher is to be used for the body-building apparatus that movable shoulder shoulder joint, articular muscle and joint tendon are used; Existing shoulder arm stretcher is outdoor type, and its defective is bulky, complex structure, it is bigger to be difficult at the noise of indoorly installing and using, send in cost height and the process used.
The utility model content: the purpose of this utility model provide a kind of volume little, simple in structure, be easy to indoorly install and use, cost is low and the little improved shoulder arm stretcher of noise that sends when using.
The purpose of this utility model is to realize like this, a kind of improved shoulder arm stretcher, comprise stay cord, be fixed on the handle and the stay cord rolling support device at stay cord two ends, the stay cord rolling support device is made up of substrate, pulley support axle, pulley, rolling bearing and hold-doun nut; Wherein an end of pulley support axle has shoulder block, and the other end of pulley support axle has external screw thread; An end that has shoulder block on the pulley support axle is fixedly installed on the side surface of substrate, and having an externally threaded end on the pulley support axle is free end; Pulley is fixedly sleeved on the outer ring of rolling bearing; The inner ring of rolling bearing is actively socketed on the pulley support axle; The hold-doun nut that the inner ring of rolling bearing is threaded on the pulley support axle free end is pressed abd fixed on the shoulder block of pulley support axle; On substrate, scatter and be provided with the substrate fixing hole that runs through substrate.
During installation, only need substrate to be fixed on the metope of doorframe entablature or doorframe top with steel nail or screw by the substrate fixing hole on the substrate earlier, successively pulley and hold-doun nut are installed to again on the pulley support axle on the substrate, at last stay cord is enclosed within on the pulley and both can, its installation is very convenient, and because the utility model saved huge support, thus its volume significantly reduce, simple in structure, cost is low, be convenient in indoor installation and use; During use, the handle left and right wheels of holding the stay cord two ends respectively with left hand and right hand is changed down the pulling stay cord and both can be carried out the stretching of left and right shoulder arm, owing to be provided with the rolling bearing that coefficient of friction is little, noise is low between pulley support axle in the utility model and the pulley, so the noise that the utility model in use sends is very little.

The specific embodiment: the utility model will be further described below in conjunction with accompanying drawing, a kind of improved shoulder arm stretcher, comprise stay cord 2, be fixed on the handle 1 and the stay cord rolling support device at stay cord 2 two ends, the stay cord rolling support device is made up of substrate 11, pulley support axle 8, pulley 5, rolling bearing and hold-doun nut 6; Wherein an end of pulley support axle 8 has shoulder block 12, and the other end of pulley support axle 8 has external screw thread; An end that has shoulder block 12 on the pulley support axle 8 is fixedly installed on the side surface of substrate 11, and having an externally threaded end on the pulley support axle 8 is free end; Pulley 5 is fixedly sleeved on the outer ring 7 of rolling bearing, can prevent that like this limited slip wheel 5 comes off on the outer ring 7 of rolling bearing; The inner ring 13 of rolling bearing is actively socketed on the pulley support axle 8, pulley 5 and rolling bearing can be disassembled on pulley support axle 8 when installation and fixing base 11 like this, so that install and fixing base 11; The hold-doun nut 6 that the inner ring 13 of rolling bearing is threaded on pulley support axle 8 free ends is pressed abd fixed on the shoulder block 12 of pulley support axle 8, like this can be because of loosening and not send extra noise with regard to making between all movable parts in the stay cord rolling support device and the fixed part; On substrate 11, scatter and be provided with the substrate fixing hole 10 that runs through substrate 11, just substrate 11 can be fixedly installed on the position that needs by substrate fixing hole 10 with steel nail or screw like this.
For the inner ring 13 that compresses rolling bearing better, between the inner ring 13 of rolling bearing and hold-doun nut 6, can also be provided with packing ring 9.
As shown in Figure 1, when the utility model is installed, need two substrate 11 left-right symmetry to be fixedly mounted on the metope 4 of doorframe entablature or doorframe 3 tops with steel nail or screw by the substrate fixing hole 10 on the substrate 11 earlier, successively pulley 5 and hold-doun nut 6 are installed to again on the pulley support axle 8 on the substrate 11, both at last stay cord 2 is enclosed within on the pulley 5 can, its installation is very convenient.
During use, handle 1 left and right wheels of holding stay cord 2 two ends respectively with left hand and right hand is changed down pulling stay cord 2 and both can be carried out the stretching of left and right shoulder arm.
