Abstract

The utility model relates to a dynamometer which is used for measuring the maximum pulling force in a laboratory, which is composed of a dial, a pointer, a spring and a hook. Compared with the existing dynamometer, the different part of the utility model is that one end of the pointer is provided with an opening, a pencil lead hole is drilled on the opening, and an elastic bolt is arranged by the opening. When the utility model is used for measuring the pulling force, a pencil lead is arranged; the spring outstretches the pointer to move, the pencil lead leaves scratches on the dial, when a measured object is pulled to be broken, the spring is bounced, and an end point of the scratches is left; a scale to which the end point of the scratches corresponds is the reading of the maximum pulling force. Therefore, the utility model can accurately read the value of the maximum pulling force and quicken the progress of experiments.

Description

新型测力计 The new dynamometer

本实用新型用于实验室测量物品最大拉力,特别适合于测量易断物品最大拉力的测力计。 The present invention for measuring the maximum tensile force laboratory items, particularly suitable for measuring the maximum tensile force frangible article dynamometer.

目前实验室使用的测力计,在测量易断物,如头发之类物品的最大拉力时,物品被拉断的瞬间,弹簧快速反弹,固定于弹簧上的指针也很快离开指向刻度盘上的刻度,所以不易读出拉力的大小,给实验的准确性带来一定的难度。 Current dynamometer laboratory use, measuring the maximum tensile force frangible object, such as the hair or the like article, the article pulled off instantly, rapid rebound spring, the spring is fixed to the pointer quickly leaving point on the dial scale, it is not easy to read tension size, the accuracy of the experiment to bring some degree of difficulty.

本实用新型为克服上述存在的不足,提供一种能固定铅笔芯的指针,使被测物达最大拉力断掉瞬间,铅笔芯在刻度盘上留下划痕,弹簧反弹回去也能准确读出物品的最大拉力。 The present invention is to overcome the above deficiencies exist, to provide a fixed pointer of the pencil, so that up to the maximum tensile force was measured instantaneously broken, the pencil scratch the dial, bounce back spring can be accurately read out the maximum tensile article.

本实用新型达到上述目的的技术方案是:测力计由刻度盘(1),指针(3),弹簧(4),挂钩(6)组成。 Object of the present invention to achieve the above technical solution: a dial gauge (1), the pointer (3), a spring (4), the hook (6) composition. 弹簧(4)的一端与刻度盘(1)上的固定点(11)连接,另一端与挂钩(6)连接,指针(3)固定在弹簧(4)上。 A spring (4) with one end of the fixed-point dial (11) (1), and the other end of the hook (6) is connected to a pointer (3) is fixed on a spring (4). 其特点是,指针(3)的一端作成开口(9),其开口处钻一个夹铅笔芯(10′)的铅笔芯孔(10)。 Characterized by an end pointer (3) is made an opening (9), which clamp a drill opening pencil (10 ') of the pencil lead hole (10). 而由开口分成的两块装有紧固铅笔芯(10′)的松紧螺栓(2)。 And the two elastic bolts fitted into the fastening opening of pencil lead (10 ') (2). 测拉力时装上铅笔芯(10′)使铅笔芯触接刻度盘(1),当达最大拉力时被测物被拉断,铅笔芯就在刻度盘上留下划痕,划痕对应的刻度便是最大的拉力。 Measured on a tensile fashion pencil (10 ') that the pencil touching the dial (1), the maximum tension reached when the measured object is pulled off, leaving on the pencil scratch on a scale, the scale corresponds to a scratch It is the biggest pull. 所以弹簧反弹回去,也能准确读出最大拉力数。 So spring bounce back, can be accurately read out the maximum number of pull.

本实用新型的铅笔芯孔(10)大于或等于2mm。 Pencil lead of the present invention the hole (10) is greater than or equal to 2mm.

本实用新型的刻度盘(1)下部及挂钩(6)固定连接,防止弹簧摆动的一组弹簧导向构件(5)。 Dials the present invention (1) and a lower hook (6) is fixedly connected, a set of springs to prevent the guide member (5) of the spring pivot.

本实用新型在指针上安装铅笔芯后,能在测量易断物最大拉力时,准确读出最大拉力大小,可加快实验进度。 After installing the pencil lead of the present invention, the pointer can be measured at maximum tensile frangible material, accurately read the maximum pulling force, to accelerate progress of the experiment.
