Abstract

The utility model provides an elongation dip stick, comprising a graduated scale, wherein, a sliding measuring component is arranged on the graduated scale. The elongation dip stick also comprises a fixed end and a free end. The fixed end is fixedly connected with the graduated scale and has a positioning pin extended out from the bottom, wherein, the central axis of the positioning pin is aligned to a zero graduation of the graduated scale. The free end is riveted with a chute of the graduated scale and moves left and right along the chute; and a surveying pin is extended out from the bottom of the free end, and an indicator is arranged on the bottom of the free end and is aligned to the central axis of the surveying pin. A guide chute is arranged in the middle of the surface of the graduated scale. The positioning pin and the surveying pin are inserted into a surveyed material, the length of the material before deformation can be surveyed; meanwhile, one end of the material is fixed by the positioning pin; and the material is drawn outwards until the material can not be drawn, the surveying pin is also drawn accordingly during the process, data indicated by the indicator is the length of the surveyed material in maximum deformation, and an elongation (commonly called tension ratio) of the surveyed material can be acquired by calculating the ratio between the length before deformation and the length after deformation. The elongation dip stick has the advantages of simple and reasonable structure, accurate survey, convenient operation and improved work efficiency.

Description

The elongation dip stick

Technical field

The utility model relates to a kind of dip stick, especially for the dip stick of measuring the resilient material elongation.

Background technology

Resilient material (as elastic cord) is the material that people use always, and it is applied widely, may be used on occasions such as clothes, furniture, medical treatment, and is well received.But because the elongation of elastic cord directly influences the amount that the user intercepts elastic cord, so all to measure calculating to its elongation in production and use.When making seat support, sofa now, the measurement of the elongation of its elastic cord is comparatively original, chooses certain-length earlier and put signs on elastic cord, again it is pulled to the limit, be put into then and measure size between the mark on the survey instrument, at last by calculating elongation (being commonly called as the Lapie).It measures loaded down with trivial details, the effort of operation, influences production efficiency greatly.

The utility model content

It is a kind of simple and reasonable that the purpose of this utility model is intended to provide, for the user brings more high efficiency elongation dip stick, to overcome weak point of the prior art.

A kind of elongation dip stick by this purpose design comprises rule, and its architectural feature is that rule is provided with the measurement assembly that slides, and it comprises stiff end and free end, and free end is fastened on the rule, and can move to obtain measurement data along rule.

Described stiff end is fixedly connected on the rule, and pilot pin is extended in the bottom, and the central axis of pilot pin is aimed at the zero graduation of rule.

Middle part, described rule surface is provided with guide chute, and free end is provided with the chute riveted joint of draw-in groove and rule, and along the chute move left and right; Surveyingpin is extended in the bottom, and the top is provided with indicateing arm, the central axis of indicateing arm alignment surveyingpin.

Pilot pin of the present utility model and surveyingpin insert tested material, can measure the length before the material deformation, and simultaneously, the material one end pin that is positioned is fixed; Be pulled outwardly material until stretchy not, this process measurement pin is also dragged, length during largest deformation that its indicateing arm indication data are tested material, and the length ratio that calculates before and after the distortion can draw the tested material elongation.It is simple and reasonable, measurement is accurate, easy to operate, can improve work efficiency.

Embodiment

Below in conjunction with drawings and Examples the utility model is further described.

Referring to Fig. 1 and Fig. 2, this elongation dip stick comprises rule 3 and slides and measure assembly that middle part, rule 3 surface is provided with guide chute 3.1.The measurement assembly that slides comprises stiff end 1 and free end 2, and stiff end is fixedlyed connected with rule 3, and pilot pin 1.1 is extended in the bottom, and the central axis of pilot pin is aimed at the zero graduation of rule.Free end 2 is provided with guide chute 3.1 riveted joints of draw-in groove and rule 3, and along its move left and right; Surveyingpin 2.2 is extended in the bottom, and the top is provided with indicateing arm 2.1, wherein the central axis of indicateing arm alignment surveyingpin.The pilot pin 1.1 of stiff end 1 is arranged on the same horizontal line with the surveyingpin 2.2 of free end 2.The center of the starting point of guide chute 3.1 and stiff end 1 is separated by a distance, and as 10cm, free end 2 can be moved to the starting point realization material spacing of guide chute 3.1 and chooses; Choose again after also can moving a certain distance outward.

Referring to Fig. 3, the principle of work of elongation dip stick is: free end 2 moves to the starting point of guide chute 3.1, and with the pilot pin 1.1 of stiff end 1 and the surveyingpin 2.2 insertion elastic cords 4 of free end 2, at this moment, the amount of choosing of elastic cord is 10cm; The to the utmost point limit for length's degree that again elastic cord pulled outward, in the drawing process, free end 2 is dragged away from the B place from A, this moment, free-ended indicateing arm 2.1 indication scales were 20cm, by calculate can this elastic cord 4 elongation be 100%.
