Abstract

The invention relates to a hold-type tensiometer, which is applied to measure weights of objects or tension limitation of materials in industrial production or daily life. The hold-type tensiometer is composed of a draw hook, a piston, a cylinder, a draw ring, spring and a magnet ring. One end of the cylinder is sealed and the other end of the cylinder is open; a tension scale is marked on the surface of the cylinder; and the cylinder surface marked by the scale is manufactured by a magnetic plate material. A spring is connected to the inner bottom of the cylinder; and the other end of the spring is connected with the piston. The piston is manufactured by a magnetic material and can make sliding movements freely inside the cylinder; the other end of the piston is connected with the draw hook. And the draw hook is extended outside the cylinder and one end of the cylinder is fixedly connected with the draw ring. When the hold-type tensiometer works, the draw ring is used to fix the tensiometer; a weighted object is hung on the draw hook or a tension is applied on the draw hook; when the magnetic piston is moved, a magnetic trace is left on the surface of the tensiometer; after the weighted object is taken away or the material is snapped, the piston is reset to an initial point and the magnetic trace is still maintained, wherein end reading is a largest tension; and after the magnet ring is sleeved on the cylinder surface of the tensiometer, the magnetic trace disappears. According to the hold-type tensiometer provided in the invention, weights of ordinary objects can be accurately measured; and tension limitation of materials can also be measured; and moreover, the hold-type tensiometer has advantages of simple structure, low cost, and simple operation.

Description

The freeze mode tautness meter

Affiliated technical field

The present invention relates to a kind of freeze mode tautness meter that can measure pulling force, especially simple in structure, easy to operate, and the freeze mode tautness meter of the energy measurement material pulling force limit again.

Background technology

In daily life or commercial production; Often need to measure the weight of various objects, perhaps the pulling force limit of certain material of measurement object is present; The weight of measuring object adopts spring balance morely; The pulling force limit of measuring certain material then needs the comparatively complicated special mechanism of structure, and operation is trouble comparatively, and cost is higher.

Summary of the invention

In order to overcome at present in commercial production or daily life, to adopt spring balance can not record the material pulling force limit, and adopt the special mechanism cost bigger; The deficiency of troublesome poeration, the present invention provides a kind of freeze mode tautness meter, and this freeze mode tautness meter not only can accurately record the weight of general object; And can measure the pulling force limit of material; And simple in structure, cost is lower, and is simple to operate.

The technical solution adopted for the present invention to solve the technical problems is: this freeze mode tautness meter is by drag hook, piston, cylindrical shell, draw ring; Spring, magnet ring is formed, the sealing of cylindrical shell one end, the other end is open-minded; The surface indicates the pulling force scale, and it indicates scale part cylindrical shell and processes by the magnetic sheet material, and the cylindrical shell inner bottom part connects a spring, the spring other end plug of taking over a job; Piston is processed with magnetic material, can in cylindrical shell, be free to slide, and another termination drag hook of piston, drag hook stretches out outside the cylindrical shell; The fixed draw ring of cylindrical shell one end during work, is fixed tautness meter through draw ring, and the suspension weight perhaps applies pulling force on drag hook; Then stay the magnetic vestige on the tautness meter surface in the magnetic piston moving process, when taking weight or material away and break back piston involution initial point, the magnetic marking still keeps; Its terminal reading is maximum pull, and magnet ring was after the tautness meter drum surface overlapped, and the magnetic marking disappears.

The invention has the beneficial effects as follows: not only the weight of general object can be accurately recorded, and the pulling force utmost point of material can be measured, and simple in structure, cost is lower, and is simple to operate.

Description of drawings

Below in conjunction with accompanying drawing and embodiment the present invention is further specified.

Accompanying drawing is the structural drawing of this freeze mode tautness meter.

In the accompanying drawing, 1. drag hook, 2. piston, 3. cylindrical shell, 4. draw ring, 5. spring, 6. magnet ring.

Embodiment

In specific embodiment shown in the accompanying drawing, this freeze mode tautness meter is by drag hook (1), piston (2), cylindrical shell (3); Draw ring (4), spring (5), magnet ring (6) is formed, the sealing of cylindrical shell (3) one ends; The other end is open-minded, and external diameter is 5-10cm, and internal diameter is 4-8cm, and length is decided according to concrete purposes; The surface indicates the pulling force scale, and scale is from spring (5) piston (2) place beginning label when being in free state, and it indicates scale part cylindrical shell and processes by the magnetic sheet material, and cylindrical shell (3) inner bottom part connects a spring (5); Spring (5) other end plug (2) of taking over a job, piston (2) is processed with magnetic material, and its thickness is 0.5-1.0cm, can in cylindrical shell (3), be free to slide; Another termination drag hook (1) of piston (2), drag hook (1) stretches out outside the cylindrical shell (3), and the fixed draw rings of cylindrical shell (3) one ends (4) are during work; Through draw ring (4) tautness meter is fixed, gone up the suspension weight or apply pulling force, then stay the magnetic vestige on the tautness meter surface in magnetic piston (2) moving process, when taking weight or material away and break back piston (2) involution initial point at drag hook (1); The magnetic marking still keeps, and its terminal reading is maximum pull, and magnet ring (6) internal diameter is slightly larger than cylindrical shell (3) external diameter; Thickness is 0.5-1.0cm, and magnet ring (6) was after tautness meter cylindrical shell (3) surface was overlapped, and the magnetic marking disappears.
