Abstract
The utility model relates to a fabric detecting instrument, which effectively improves the existing pre-tension device of a single yarn strength tester to solve the problems of complex pre-tension adjustment, inconvenient use, low accurate rate, etc. The utility model is characterized in that one end of a balance bar is provided with a step weight and a fixing rod thereof, and the other end is provided with a moveable weight to match and adjust pre-tension; a self-tightening yarn clamping head forms a pin shape; the contact surface of the self-tightening yarn clamping head and the balance bar is an inclined plane; the self-tightening yarn clamping head is movably arranged on the balance bar; the upper side of the balance bar is provided with an upper gag lever post.
Description
The utility model relates to a kind of textile lab instrument.
At present, single thread force-machine gives tensioner and adopts lever principle, and version is that supporting seat flexibly connects balance stem, adjustable counterweight is established on the balance stem both sides, and the yarn clipping end is established yarn clamping head, and yarn clamping head and balance stem surface of contact are the plane, need lift the yarn clamping head knob during yarn clipping, yarn be put given.The company's of adjusting limit counterweight is adjusted and is given tension force.Balance stem one side is established a lower limit.There is defective in this structure: 1. the both sides counterweight is regulated simultaneously, the adjustment process trouble; 2. balance stem is supreme spacing, and the lever angle is drawn the consistent rate variance of yarn at every turn, survey that to give tension force accurate inadequately; 3. need use two manual manipulations during yarn clipping, test is wasted time and energy, and uses inconvenience.
The purpose of this utility model provides a kind of novel single thread force-machine and gives tensioner, uses trouble to overcome existing apparatus, wastes time and energy and surveys the coarse problem of tension force of giving.
The utility model is to give on the tensioner architecture basics at existing single thread force-machine, forms through further improving.Specifically it is to regulate adjustable counterweight by present balance stem both sides, changes the removable counterweight of an end into, and the other end is provided with fixed bar and places the stepping counterweight, establishes the upper limit bar above the yarn clipping end, with limiting balance bar equilibrium point, guarantees to give to add tension force, the moment unanimity.Gag lever post is set with limiting balance bar corner in the below.Yarn clamping head changes nail type self-tightening yarn clamping head into by present plane cylindricality, and this self-tightening yarn clamping head and balance stem surface of contact are the inclined-planes, self-tightening yarn clamping head axle sleeve spring, and axle head is provided with rotary nut, with the self-tightening power of adjustable clamp loose thread.Nail type self-tightening yarn clamping head and spring are movably housed on the balance stem.Balance stem is movably arranged on the fixed base plate with supporting seat.
The utility model is according to giving the tension force size, and an end is placed the stepping counterweight, regulates the removable counterweight of the other end, and is easy to adjust.One hand draws yarn on self-tightening yarn clamping head during yarn clipping, and is time saving and energy saving, and the yarn clipping end is provided with the upper limit bar, gives uniform tension in order rate height, and test data is accurate.
Introduce the utility model embodiment in detail below in conjunction with accompanying drawing
Fig. 1 is the utility model structural representation.
Fig. 2 is the utility model self-tightening yarn clamping head structural representation.
Know that by Fig. 1 balance stem of the present utility model (1) is movably arranged on the fixed base plate (3) with supporting seat (2).Balance stem (1) is provided with fixed bar (5) and the self-tightening yarn clamping head (6) of placing stepping counterweight (4) on one side, and upper limit bar (7) is established in yarn clipping end top, and gag lever post (8) is set in the below, and gag lever post is fixed on the fixed base plate (3) up and down; The other end adopts removable counterweight (9), with stop screw (10) location.Know that by Fig. 2 self-tightening yarn clamping head (6) is the nail type, self-tightening yarn clamping head (6) is the inclined-plane with balance stem (1) surface of contact, axle sleeve spring (11), and nut (12) is movably housed in nail type self-tightening yarn clamping head (6) and spring (11) on the balance stem (1).
Claims (2)
1, a kind of single thread force-machine of being made up of supporting seat, balance stem, removable counterweight, lower limit bar etc. gives tensioner, it is characterized in that balance stem one end establishes stepping counterweight and fixed bar thereof, nail type self-tightening yarn clamping head is movably housed on the balance stem, with the balance stem surface of contact be the inclined-plane, the balance stem upside is provided with the upper limit bar.
2, single thread force-machine according to claim 1 gives tensioner, it is characterized in that nail type self-tightening yarn clamping head axle sleeve spring, and axle head is provided with rotary nut.
