Description

Stainless steel coated dumbbell

The utility model relates to a kind of stainless steel and coats the dumbbell of making, and mainly provides a kind of manufacturing simple and easy, and the dumbbell product of the tool stainless steel characteristics that are difficult for getting rusty, makes the outward appearance of dumbbell more attractive in appearance, more accords with purpose safe in utilization.

Dumbbell is simple and the most common general motion utensil, so its wide welcome main cause is that its mobility is fine, is suitable for the training of arm strength, does not need other auxiliary implements can finish motion voluntarily fully.And generally cast the dumbbell of type; mostly make by cast iron; at first iron surface is owing to directly grasp with hand when motion; a large amount of sweat that hand is discharged when motion are built-up in the surface of dumbbell; be easy to make the surface oxidisation of irony; how the dumbbell of adding motion Hou directly is placed on the extremely heavy ground surface of moisture or storeroom inside; because the relation of chemical action; regular meeting forms the iron rust of thin film shape on the surface of dumbbell; not only unbecoming but also hinder the certainty that motion grips; have a strong impact on the security that whole motion is implemented; for asking the bad situation that effectively overcomes in the above-mentioned use; so just produce a kind of dumbbell, prevent the purpose of getting rusty to reach with electroplating surface protection.

But because the dumbbell of general plating formula design, its whole manufacturing process is very loaded down with trivial details, as shown in Figure 5, at first prepare partly by material, according to the iron material of selected dumbbell manufacturing usefulness such as the weight of estimating and the big or small volume of timber or the material of casting, material is sent in the saw cutting implement cutting 30 to suitable size, insert the procedure for processing of the enterprising driving surface treatment 31 of car system machine again, make it reach correct size, the workpiece that to process Hou is again carried out the boring processing 33 of an end, and insert group used when it mainly interconnected for middle connecting rod; To hole in addition processing 33 Hous workpiece through polish 34, pickling 35, in and 36 processing Hous carry out electroplating processes 37 again, make its surface plate the smooth protective layer of one deck, can become the finished product of a dumbbell.

From above-mentioned whole dumbbell manufacture process, can obviously find out suitable loaded down with trivial details, not only time-consuming but also because manufacture process in must be through the multiple tracks chemical treatment, as pickling 35, in and 36 and electroplate 37 etc., all need add special chemical agent, its problem of environmental pollution that causes is that industry is worried and perplexed always, and be to solve the many environmental issues that produced in the above-mentioned manufacturing, the cost that drops into also will increase relatively, even increase with production cost, and the dumbbell product made from above-mentioned plating, though its surface is gone up plating and has been protected the layer protecting film layer, but because the protective layer that dress plate in institute is as thin as a wafer, drop an accidentally ground or touch hard or during article that point is given prominence to, surperficial coating is come off slightly when in the use of dumbbell, grasping, and losing the effect of protection, the surface that comes off may produce the phenomenon of corrosion immediately; Therefore the outer surface that how to make dumbbell not only firmly and but also can often protect the operating characteristic that light can not get rusty, become assistant officer's problem to be solved.

Main purpose of the present utility model is to provide a kind of dumbbell that coats with stainless steel substrates, makes it reach the smooth surface purpose that can not get rusty attractive in appearance.

Stainless steel of the present utility model coats the dumbbell of making, and its primary structure design includes the dumbbell body and connects connecting rod between two bodies; Its characteristics are: the stainless steel plate cutting punching out of full wafer is become two relative cup-shaped plates, and in be reserved with the concave ring groove that falls through car surface-treated dumbbell body outer ring surface stage casing, the stainless steel cage branch of two cup-shapeds is coated whole dumbbell body by dumbbell both sides insert group, and the stainless steel substrates of coating is bent in the concave ring groove according to the concave ring groove of reserving on the body anchor ring, the whole dumbbell body of certain coating forms a complete dumbbell shape.

Described stainless steel coats the dumbbell of making, and it coats the concave ring groove place, outer ring surface stage casing of the dumbbell of Hou, can one soft rubber ring pad suit.

The utility model makes the outward appearance of dumbbell more attractive in appearance because the dumbbell body that has adopted stainless steel to coat makes its phenomenon that corrosion can not take place, and safe in utilization.

For further specifying structure of the present utility model, characteristic and practical purpose thereof describe in detail below with reference to accompanying drawing:
