The Gauge board 3 that extends before and after this chain abrasion degree measurer comprises one, but reach the measuring plate 4 that a horizontal pivot is hubbed at these Gauge board 3 end faces with putting.
This Gauge board 3 comprises that the body that extends before and after one 31, a consubstantiality are fixed in the scale sign portion 32 of these body 31 front ends, and one from this section bottom surface, body 31 rear end the shaft-like backstay portion 33 of projection down.These scale sign portion 32 left surfaces are concaved with a breach that runs through up and down 320, and its end face indicates to have and a plurality ofly is that arcuation extends and the change in size scale 321 of inside and outside distribution radially, and each change in size scale 321 all indicates at interval a plurality of scale symbols 322 of representing the chain abrasion degree respectively, change in size scale 321 is chains 9 of corresponding respectively different size specification and designing, for example bicycle chain, locomotive chain ... Deng, so the spacing of the scale symbol 322 on the change in size scale 321 and the size of representative are not quite similar.
In the present embodiment, it is inside to be provided with three footpaths, the outer distribution, and represent the change in size scale 321 of three kinds of different chain specifications respectively, the scale symbol 322 of change in size scale 321 left ends indicates respectively " 520 ", " 428 ", " 420 ", wherein, " 5 " represent two adjacent axis 902 spacings is the chain of 15.875mm, " 4 " represent two adjacent axis 902 spacings is the chain of 12.7mm, " 420 " are to represent different chains to roll the chain of 905 external diameters respectively with " 428 ", and the scale symbol 322 in each change in size scale 321: " 0 ", " 0.5 ", " 1.0 " and " 1.5 ", be the length growth rate of representing chain 9 respectively, for example " 0.5 " is that to represent chain 9 length growth rates be 0.5%.But when implementing, change in size scale 321 quantity are not as limit.
This measuring plate 4 comprise one can before and after pivot pendulum ground horizontal pivot be located at these scale sign portion 32 end faces inspect plate body 41, and one be mounted on up and down with extending this inspect plate body 41 bottom surfaces against the body of rod 42.
This inspects plate body 41 is to be the lengthy motion picture shape, and have a form end 411 and interlock end 414 that lays respectively at its 410 liang of opposition sides in pivot axle center, this form end 411 is to be positioned at this scale sign portion 32 end faces, and turn right and extend across this scale sign portion 32 right borders, and this scale sign portion 32 pivots pendulum displacement relatively, and it is inswept gradually along the length direction of change in size scale 321, and have one and run through up and down and extend and cross over the form 412 of change in size scale 321 along its length direction, and two be arranged with in its end face respectively and refer to scale 413 from the opposite strip mark that extends outward of 412 liang of ora terminalis of this form respectively, this form 412 can be for the scale symbol of down watching on the change in size scale 321 322, mark refers to that scale 413 can be respectively refers to scale symbol 322 on the change in size scale 321 make things convenient for user's identification scale value in order to mark.
This interlock end 414 is breach 320 tops that expose to this scale sign portion 32, and can be by this form end 411 interlock pivots pendulum, should be down to extend across this scale sign portion 32 bottom surfaces from these 414 bottom surfaces, interlock end against the body of rod 42, and can be, and swing at these breach 320 places by these interlock end 414 interlocks.
See also Fig. 3, Fig. 4 and shown in Figure 5, wherein Fig. 5 is the side view of Fig. 4.When the utility model chain abrasion degree measurer uses, can and should down be plugged in respectively in the predetermined engaging hole 900 of chain 9 this backstay portion 33 against the body of rod 42, and make this backstay portion 33 be close proximity to the posterior edges 901 of this engaging hole 900 backward, this Gauge board 3 is pulled the form end 411 that this inspects plate body 41 backward relatively then, interlock makes this interlock end 414 drive and should swing against the body of rod 42 forward, make this forward edge 901 that abuts against the engaging hole 900 of corresponding plug-in mounting against the body of rod 42 toward front limit, and then chain 9 is opened up to maximum length between this backstay portion 33 and against the section to be measured 90 front and back support of 42 of the bodies of rod.
At this moment, can be according to the dimensions of this chain 9, find out corresponding change in size scale 321 in this scale sign portion 32, and by the scale symbol 322 in the form 412 that exposes to this form end 411, and mark refers to the scale symbol 322 that scale 413 marks refer to, learn the length variations amplitude that this chain 9 causes because of abrasion at once, go up suitable convenience so use.
In sum, the design of the change in size scale 321 of multiple different chain 9 specifications is arranged by portrayal simultaneously on this Gauge board 3, and the structural design that is hubbed at the measuring plate 4 on this Gauge board 3, can be in order to accurately measure the length variations amplitude that chain 9 causes because of abrasion, and can be applicable to the abrasion degree that measures multiple chain 9 simultaneously, and use easy and simple to handle, quite convenient and practical.
The above, it only is preferred embodiment of the present utility model, be not that the utility model is done any pro forma restriction, though the utility model discloses as above with preferred embodiment, yet be not in order to limit the utility model, any those skilled in the art are not in breaking away from the technical solutions of the utility model scope, when the technology contents that can utilize above-mentioned announcement is made a little change or is modified to the equivalent embodiment of equivalent variations, in every case be the content that does not break away from technical solutions of the utility model, according to technical spirit of the present utility model to any simple modification that above embodiment did, equivalent variations and modification all still belong in the scope of technical solutions of the utility model.
