Gas spring force measurer

Abstract

The invention relates to the field of detection of spring force, in particular to a gas spring force measurer, which comprises a first rod and a second rod. The first rod and the second rod are mutually hinged, a rod body of the first rod and a rod body of the second rod are respectively hinged with two ends of a gas spring, the first rod is provided with a pulley, the second rod is provided with a rotatable take-up reel, one end of a stay cord connected with a dynamometer is fixed on the second rod, the other end of the stay cord is fixedly wound on the take-up reel after being wound around the pulley, the gas spring is mounted between the first rod and the second rod in a free state, at the moment, the gas spring is in a longest extension state, the take-up reel rotates to pull the stay cord, so that an included angled between the two rods is reduced, the gas spring is compressed, the take-up reel stops rotating when the gas spring is compressed at an optional length, a numerical value on the dynamometer is read, and an elasticity value of the gas spring can be calculated according to geometrical relationship. The gas spring force measurer is simple in operation, low in cost, small in size, convenient to carry and wide in application range.

Description

technical field [0001] The invention relates to the field of spring force detection, in particular to a gas spring force value measuring device. Background technique [0002] A gas spring is an accessory that can perform functions such as support, buffer, brake, height adjustment, and angle adjustment. At present, this product has been widely used in medical equipment, automobile, furniture, textile equipment, processing industry and other fields. However, the processing accuracy, sealing performance and operating environment temperature of the gas spring have a great influence on the force value of the gas spring. In a low-temperature environment, the support force provided by the gas spring becomes smaller, resulting in a smaller opening force or even being unable to keep the front and rear covers fully open, while in a high-temperature environment, the closing force of the front and rear covers becomes larger, so it is necessary to check the gas spring before assembly. ...

Problems solved by technology

However, the processing accuracy, sealing performance and operating environment temperature of the gas spring have a great influence on the force value of the gas spring. In a low-temperature environment, the support force provided by the gas spring becomes smaller, resulting in a smaller opening force or even being unable to keep the front and rear covers fully open, while in a high-temperature environment, the closing force of the front and rear covers becomes larger, so it is necessary to check the gas spring before assembly. Whether the spring force value meets the relevant technical requirements, and verify whether the gas spring can meet the use requirements in harsh environments (high and low temperature)

At present, most of them use spring tension and compression testing machines for measurement. Using this method of measurement is not only complicated to operate, but also requires special fixtures; moreover, the equipment is expensive and difficult to carry.
