Description

Yarn tensiometer

The utility model relates to and a kind ofly the tension force of chemical fiber filament, yarn, glass fibre and metal wire-drawing etc. in moving is carried out the tensiometer of dynamic measurement at weaving or other in about industry.

Existing yarn tension instrument has mechanical type, condenser type, resistance-strain chip, photo-electric etc., profile is generally hand-held, mainly comprise several parts such as measuring head, sensor and shell thereof, handle, circuit board, power supply and LCDs from A-P, power supply is a dry cell.Because yarn adds present position difference in man-hour on various boards, when aiming at yarn mensuration with tensiometer, the LCDs that is positioned at the tensiometer rear portion can only be pointed to single direction, can not need regulate by test, causes mensuration personnel observation data difficulty.The measuring head of the portable tensiometer of R-045 type that the special company of Switzerland Luo Si makes can turn round 120 °, the yarn of horizontal or vertical state is carried out tension force detect more conveniently, but display screen still can only point to a direction.In the high-order bit or low position yarn measure personnel when detecting and still can't directly read shown data, use to be subjected to very big restriction.

For overcoming above-mentioned defective, the utility model has designed the rotatable hand-held tensiometer of a kind of display screen, and its monoblock type is improved to separate form, and measure the needs of the yarn tension that is in diverse location to adapt to different occasions, make display screen select required direction simultaneously according to different occasions.

Architectural feature of the present utility model is as follows.It is a kind of hand-held form yarn tension instrument that adopts high precision composite electron sensing element, mainly comprises several parts such as measuring head, sensor and shell thereof, handle, circuit board, digital display screen, dry battery power.Its principal character is that the tensiometer handle is divided into two with the case design of upper part, and wherein one for the cross section is trapezoidal revolving die, and an end of revolving die has and the handle rotating disk of the band spill chute that connects of embedding mutually, and described rotating disk embeds in the spill chute of handle inwall.Can relatively rotate by trapezoidal revolving die of the interaction of two chutes and handle.For preventing not have relatively rotating of placing restrictions between trapezoidal revolving die and the handle, the fixing stop stator that protrudes of a slice on revolving die rotating disk inwall, then establish a stop fulcrum that protrudes at the handle runner place, when trapezoidal revolving die and handle relatively rotate to described stator when contacting with fulcrum along a direction, rotation can't continue, contact with the opposite side of stator and can only relatively rotate until fulcrum, make thus to relatively rotate angle control within limits along another direction.The other end inwall of revolving die is provided with the spill chute, and with the rotating disk of the display screen housing of band spill chute mutually embedding connect, realize relatively rotating of revolving die and display screen housing by two chute effects; For preventing unrestrictedly to relatively rotate between display screen housing and revolving die, the fixing stop stator that protrudes of a slice on display screen housing rotating disk, near revolving die inwall spill chute, establish a stop fulcrum that protrudes, when revolving die and display screen housing relatively rotate to described stator when contacting with fulcrum, rotation can't continue.Be that convenient yarn tension to the machine depths measures, the handle portion and the sensor outer housing of tensiometer partly separated that two bodies before and after tensiometer is divided into middlely are connected sensor with lead with power supply, display screen.

The utility model has the advantages that,, utilize the satisfied display screen display direction of the rotatable selection of trapezoidal revolving die and display screen housing, conveniently read tension value according to the position difference of tested yarn; Because tensiometer can be divided into two bodies, be convenient to the tension detection of machine depths yarn simultaneously, simple, convenient.
