Embodiment

Below in conjunction with accompanying drawing, the invention will be further described:

As shown in Figure 1, 2, the present embodiment includes the substrate 1 of firm bamboo one-tenth, this substrate 1 is strip, this substrate 1 is divided into bottom 11, transition part 12 and support portion 13 along its length successively, support portion 13 via transition part 12 upwards and towards bottom 11 bendings, transition part 12 forms the arc of an approximate U-shaped, the centering angle of this arc is 120 °, two openings of this arc respectively with bottom 11 and support portion 13 integrative-structures, also adopt same bamboo, and make along the rift grain direction of this bamboo.The scale 131 that extends a strip on support portion 13 apart from the distal-most end of transition part 12 towards bottom 11, this scale 131 is tabular, and the upper surface of scale 131 is with weight scale; On bottom 11 apart from the distal-most end of transition part 12 offer one with the suitable through hole 111 in scale 131 cross sections, this through hole 111 can be inserted in wherein for scale 131.Herein, the upper and lower relation of bottom 11 and support portion 13 is just named with reference to the accompanying drawings, certainly, also can adopt support portion 13 to be positioned at 11 belows, bottom, the structure of 13 tops, 11 displacement support portion, bottom, accordingly, scale is positioned at through hole 111 belows, and scale 131 is arranged in through hole 111 from bottom to top.On scale 131, the scope of weight scale is positioned at 20-80kg, is altogether carved with 7 segment length's bar scales, represents respectively 20kg, 30kg, 40kg to 80kg; Every two adjacent rectangular is carved with a billet scale, and every billet scale represents 5kg.

In the time that human body station is on support portion 13, bear after acting force support portion 13 will be force transmission to transition part 12, because transition part 12 compressive strength are very strong, thus can not fracture, and only can produce bending to a certain degree, original centering angle is diminished.In the time that the centering angle of transition part 12 diminishes, the support portion 13 being connected with transition part 12 will and then be bent downwardly, scale 131 on support portion 13 will move downward along with support portion 13 simultaneously, because scale 131 is inserted in through hole 111, scale 131 will slide in through hole 111 so, and through hole 111 peripheries can be used as the pointer of weight scale on mark scale 131.In the time that scale 131 moves to a position, through hole 111 peripheries will point to some weight scales on scale 131, and this weight scale has represented the human body weight standing on support portion; Accordingly, what bore support portion 13 varies in weight, and on scale 131 corresponding weight scale also by difference.

In order to make support portion 13 can support larger weight, so that the middle part of support portion 13 is the arcuate structure upwards swelling.Can guarantee that like this support portion 13 can play rational support effect, and the arcuate structure that upwards swell at 13 middle parts, support portion is similar to the structure of arch bridge, with respect to planar structure, the arcuate structure of this protuberance makes support portion 13 can support larger weight, thereby improves the upper limit of weighing of bamboo scale.

For the scale 131 that guarantees to be arranged in through hole 111 has enough spaces, also be that scale 131 passes the length of through hole 111 when the longest, scale 131 is not interfered by the supporting plane of bottom 11 or support bamboo scale, so towards support portion 13 perks, this perk place plane and bottom 11 place planes are 15 ° of angles by through hole 111 positions on bottom 11.Due to bottom 11 through hole 111 position perks, corresponding arranging highly also of through hole 111 is enhanced, the scale 131 movement locus relative level faces that make to be inserted in through hole 111 rise, while guaranteeing scale 131 stretching motion, there are enough spaces to move, and the length of scale 131 strokes corresponding be the range of weighing of bamboo scale, also guaranteed the range of weighing of this bamboo scale.

While just having stood on support portion 13 due to human body, people knows from experience to 13 1 of support portions instantaneous pressure, this pressure is often larger, occurs irreversible distortion or fractures, thereby affect the serviceable life of bamboo scale and the effect of weighing so supporting foot 132 can prevent support portion 13 because of the pressure increasing suddenly.In addition, supporting foot 132 is two, and supporting foot 132 is positioned at the position away from transition part 12 on support portion 13, and this supporting foot 132 is bent to form cambered surface towards bottom 11, and this cambered surface and bottom 11 are slidably matched.In addition, two supporting foots 132 lay respectively at axial both sides, support portion 13 (support portion 13 axially can be considered substrate 1 axially, the length direction that is axially substrate 1 of substrate 1, bottom 11 axially also can be considered substrate 1 axially).In order to make one-piece construction optimization, improve the utilization factor in space, so scale 131 is positioned at the central authorities of two supporting foots 132, and scale 131 be positioned at support portion 132 axially on, in like manner, through hole 111 positions of bottom 11 are corresponding with scale 131 positions, and this through hole 111 is positioned in the axial direction of bottom 11.

Time in early summer, the part bamboo 40cm that can grow tall for a day, so adopt bamboo as raw material except the high reason of intensity, also because bamboo resource is many.Bamboo is before female bamboo shoot are unearthed, and its joint number has just been determined, no longer increases newly joint after being unearthed, and only increases the distance of joint and internode, and a joint is longer thinner than a joint.The unique shape of this lower thick upper thin of bamboo, make the compressive stress approximately equal in bamboo each cross section under Gravitative Loads, be approximately " equal stress bar ", that is to say that the depression bar cross section of bamboo under Gravitative Loads is ideal, so the length direction of substrate 1 adopts bamboo rift grain direction to arrange.Meanwhile, in order to improve the intensity of bamboo scale entirety, postpone the serviceable life of bamboo scale, so through hole 111, scale 131, supporting foot 132 and substrate 1 adopt integrative-structure.

In the present invention, bottom 11 and support portion 13 on substrate 1 connect by transition part 12, and this transition part 12 not only plays connection supporting role, and be the main weight bearing area of bamboo scale, in the time that human body station is on support portion 13, the gravity that human body acts on support portion 13 will make transition part 12 bend, because transition part 12 has certain anti-bending strength, so transition part 13 can not fracture, and can be reacted on degree of crook according to the size of suffered gravity; Now, scale on support portion 13 also and then declines the drops that is subject to along with support portion 13, scale 131 will axially be moved along through hole 111 through hole 111 is interior so, according to the relevant numerical expression that calculates in advance and obtain, can support portion 13 acting force that bears is corresponding with transition part 12 angle of bend, and transition part 12 angle of bend are corresponding at the interior amount of movement of through hole 111 with scale 131, the weight of finally reading human body by the amount of movement of scale 131.Although represent in the present invention that the numerical value of body weight is a general numerical value, cannot accomplish as the precision as electronic scales, but this can meet most of women's use needs, each need record a large probable value, can brake the body weight of oneself in what kind of scope, then arrange in pairs or groups and motion exercise by corresponding diet, can realize the control to self body weight; In addition, the present invention adopts the bamboo of environmental protection and pure natural to make, and one-piece construction is simple, does not only need the consumption of the additional energy source such as hardware and battery, and has higher compressive strength, is conducive to improve the serviceable life of bamboo scale.
