Embodiment 1
[0060] The following is attached Figure 1-17 The present invention is described in further detail.
[0061] A safe and reliable upper body exercising device, such as Figure 1-17 As shown, including a base plate 1, two groups of upper limb exercise units 2 are arranged symmetrically on both sides of the upper portion of the base plate 1, and the upper portion of the base plate 1 is provided with a support unit 3 between the two groups of upper limb exercise units 2;
[0062] The two groups of upper limb exercise units 2 all include a boss 6 fixedly installed on the top of the base plate 1, the upper surface of the boss 6 is provided with a chute 7, and the inside of the chute 7 is slidably installed with a slider 10. A vertical pole 11 is fixedly installed on the upper surface of the slider 10, and a U-shaped bracket 12 is fixedly installed on the upper end of the vertical pole 11, and the upper part of the U-shaped bracket 12 is fixedly installed with a support through an a...
Embodiment 2
[0074] The difference from Example 1 is that the handle 15 is also covered with a protective cover, and the protective cover is prepared by the following method:
[0075] Take the following raw materials and weigh them by weight: 30 parts of methyl vinyl phenyl silicone rubber, 15 parts of polyurethane, 10 parts of calcium carbonate powder, 15 parts of phenolic resin powder, 2 parts of p-phenylenediamine, 2 parts of triethanolamine 3 parts, 3 parts of paraffin oil, 3 parts of tricresyl phosphate;
[0076] S1. Put the weighed methyl vinyl phenyl silicone rubber and polyurethane into a pulverizer for pulverization. The speed of the pulverizer is set at 600r / min to prepare a pulverized mixed material, and pulverized the mixed material The particle diameter is 4mm;
[0077] S2. Put the pulverized mixed material prepared in step S1 into a banbury mixer for banburying. The temperature of the banbury mixer is set at 180° C., the speed is set at 700 r / min, and the banburying time is ...
Embodiment 3
[0083] The difference from Example 2 is the preparation of the protective cover, and its specific preparation method is as follows:
[0084] Take the following raw materials and weigh them by weight: 35 parts of methyl vinyl phenyl silicone rubber, 18 parts of polyurethane, 11 parts of calcium carbonate powder, 18 parts of phenolic resin powder, 3 parts of p-phenylenediamine, 3 parts of triethanolamine 4 parts, 4 parts of paraffin oil, 4 parts of tricresyl phosphate;
[0085] S1. Put the weighed methyl vinyl phenyl silicone rubber and polyurethane into a pulverizer for pulverization. The speed of the pulverizer is set at 700r / min to prepare a pulverized mixed material, and pulverized the mixed material The particle diameter is 7mm;
[0086] S2. Put the pulverized mixed material prepared in step S1 into a banbury mixer for banburying. The temperature of the banbury mixer is set at 190° C., the speed is set at 750 r / min, and the banburying time is 30 minutes to obtain banbury ...
