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
The utility model is used for laboratory measurement article maximum pull, is particularly suitable for measuring the dynamometer of easily broken article maximum pull.
The dynamometer of laboratory use at present, measuring easily broken thing, during as the maximum pull of hair and so on article, the moment that article are broken, spring rebounds fast, the pointer that is fixed on the spring also leaves the scale that points on the index dial very soon, so be difficult for reading the size of pulling force, brings certain degree of difficulty for the accuracy of experiment.
The utility model is the deficiency that overcomes above-mentioned existence, and the fixedly pointer of pencil-lead of a kind of energy is provided, and makes measured object reach maximum pull and breaks moment, and pencil-lead stays cut on index dial, springback go back also can accurately the read maximum pull of article.
The technical scheme that the utility model achieves the above object is: dynamometer is by index dial (1), pointer (3), and spring (4), hook (6) is formed.One end of spring (4) is connected with point of fixity (11) on the index dial (1), and the other end is connected with hook (6), and pointer (3) is fixed on the spring (4).Be characterized in that an end of pointer (3) makes opening (9), its opening part bores the pencil-lead hole (10) of a folder pencil-lead (10 ').And the two packaged elasticity bolts (2) that fastening pencil-lead (10 ') are arranged that are divided into by opening.Load onto pencil-lead (10 ') when surveying pulling force and make pencil-lead touch index dial (1), measured object is broken when reaching maximum pull, and pencil-lead just stays cut on index dial, and the scale of cut correspondence is maximum pulling force.So springback goes back, also can accurately read the maximum pull number.
Pencil-lead of the present utility model hole (10) is more than or equal to 2mm.
Index dial of the present utility model (1) bottom and hook (6) are fixedly connected, prevent one group of spring ways (5) of spring swing.
The utility model can accurately be read the maximum pull size when measuring easily broken thing maximum pull after pencil-lead is installed on the pointer, can accelerate the experiment progress.
Be described further below in conjunction with accompanying drawing.
Accompanying drawing 1 is the structural drawing of dynamometer.
Accompanying drawing 2 is the left side view of accompanying drawing 1.
Accompanying drawing 3 is the A-A profile of accompanying drawing 1.
Among the figure: 1-index dial, 2-elasticity bolt, 2 '-bolt hole, 2 "-degree of tightness nut, 3-pointer; 4-spring, 5-ways, 6-hook, 7-scale, 8-cut terminal point; 9-opening, 10-pencil-lead hole, 10 '-pencil-lead, 11-point of fixity, 12-handle.
Pointer of the present utility model (3) is cut a thin opening (9) open from an end pointer tip center, and in the pencil-lead hole (10) that opening (9) locates to bore a column (1), its diameter should be more than or equal to 2mm.Pointer (3) bores an elasticity bolt hole (2 ') by opening (9), dress elasticity bolt (2) in its hole.Pointer (3) is contained on the spring (4); Spring (4) one ends are connected on the point of fixity (11) of index dial (1), and the other end is connected with hook (6).The fixedly connected one group of spring ways (5) identical with existing structure of index dial (1) bottom and hook (6) prevents the spring swing.
The course of work of the present utility model is: at first (2 ") are unclamped, and pencil-lead (10 ') is loaded in the pencil-lead hole (10), make pencil-lead touch index dial (1), tighten degree of tightness nut (2 ") again with the nut of elasticity bolt (2).Afterwards measured object is hung on the hook (6), hold handle (12), one pulls the measured object (not shown), spring (4) elongates, pointer (3) is along with moving, move at the beginning pencil-lead (10 ') begins to stay initial cut on index dial (1), when the moment that measured object is broken, pen travel is to as the dotted line position among Fig. 2, spring quicks rebound, pencil-lead (10 ') stays cut terminal point (8) on index dial (1), the pairing scale of cut terminal point (8) (7) promptly is maximum pulling force reading.
Claims (3)
1. dynamometer that is used for the laboratory measurement maximum pull, it is by index dial (1), pointer (3), spring (4), hook (6) is formed, one end of spring (4) is connected with point of fixity (11) on the index dial (1), the other end is connected with hook (6), pointer (3) is fixed on the spring (4), it is characterized in that, one end of pointer is opening (9), and its opening part has the pencil-lead hole (10) of folder pencil-lead (10 '), and the elasticity bolt (2) of the two packaged fastening pencil-leads (10 ') that are divided into by opening.
2. dynamometer according to claim 1 is characterized in that, pencil-lead hole (10) are more than or equal to 2mm.
