Measure the sofa shake allowance by moving chi in theory, the extended line of so moving chi and the interface point of level ground are round dot.No matter how the sofa angle changes, perhaps duplicate measurements, under the identical situation of power that moving chi applies the sofa back of the body at every turn (moving chi is carried on the back under the prerequisite that fully contacts with sofa), the extended line of moving chi and the interface point of level ground, be that round dot all overlaps, its conformance with standard makes this measuring method become possibility to back of the body shake allowance, back of the body residue shake allowance definition requirement.
Advantage of the present invention is: 1, this detection method can detect sofa back of the body shake allowance, back of the body residue shake allowance easy, quickly, has both improved work efficiency, has improved accuracy of detection again, reduces the error rate in measurement, the metering process.2, the measuring instrument of this method use is simple in structure, easy to operate, quick, stability is high.And can measure the sofa of various angles.3, applied widely, be fit to the measurement of various angles.
Description of drawings:
Fig. 1 is the structural representation of measuring instrument.
Embodiment:
A kind of sofa shake allowance detection method is carried out according to the following step: 1. instrument is lain in the sofa back suitable location that is under the original free state, the angle of reading is counted zero clearing; 2. after passing through long duration test, under guarantor's carrier strip spare instrument is lain in sofa back suitable location, the angle number of reading is carried on the back shake allowance X exactly; 3. under unloading condition, the angle number that records is once more carried on the back residue shake allowance Y exactly.
As shown in Figure 1: the measuring instrument that sofa shake allowance detection method is used, by base 1, laterally square tube 2, be sleeved on horizontal pipe 3, vertical pipe 4 in the horizontal square tube, be installed in the vertical bloom 5 on the vertical pipe, moving chi 6, angular transducer 7 and display 8 and form.Moving chi is fixed on the axis of angular transducer, and angular transducer is installed on the horizontal pipe and with display and is connected by data line 11; On moving chi and base, spirit bubble 9 is housed respectively.Display is fixed on vertical bloom and the vertical pipe by spring shaft hinge, draw-in groove.Be equipped with between vertical bloom and the horizontal square tube and connect steel plate 12.
Above-mentioned vertical pipe is made up of inside and outside sleeve pipe 13,14, and two sleeve pipes connect by adjustable lock ring 15; Inner sleeve upper end is fixed with vertical bloom, and inner sleeve one side has a perpendicular elongated slot 16, is fixed on little steel disc 17 on the stable disk 10 and passes outer tube and insert in this groove, makes the inner sleeve can only vertical up-or-down movement, can not rotate.The sidepiece of vertical pipe is equipped with spanner cover 18, and hexagonal spanner 19 is housed in it.
Laterally pipe is arranged in the above-mentioned horizontal square tube movably, and laterally the adjustable screw 20 on the horizontal square tube of moving through of pipe is regulated (fixing or it is moved forward and backward by a small margin); Laterally between square tube, connection steel plate and the vertical bloom a corresponding elongated slot 21 is arranged respectively, V-shape elastic wire 22 is housed in the groove, major part is contained in the vertical bloom, and the width of groove is slightly larger than steel wire diameter, and steel wire can freely be seesawed.One on steel wire by steel plate and laterally square tube penetrate on the horizontal pipe than in the bigger hole of steel wire diameter, the one diameter screw hole 23 bigger than the width of groove arranged the groove center position of sidepiece on one side at vertical bloom, adjust the Zhang Du (dynamics) of steel wire in the groove, the effect of this steel wire: 1) horizontal pipe can be moved forward and backward with adjustable screw in the horizontal square tube of square-outside and round-inside.2) prevent that horizontal pipe from rotating.
4 angles of above-mentioned base are equipped with adjustable screw 24 and nut 25 respectively.
The using method of this measuring instrument is:
1, when sofa is in the original free state, instrument is placed on sofa behind, move chi apart from sofa behind center line suitable location, and with the base level-off.When sofa when behind the center is soft, after instrument can being placed on sofa and carrying on the back any back of the body watchman's wooden clapper.
2, regulate height of instrument, make the chi meta be positioned at sofa center, face upper edge behind, adjust adjustable lock ring, level altitude with hexagonal spanner.
3, under the base horizontality: open display, the stable disk on the vertical pipe is pressed in one have gentle hands, promote base with horizontal direction on the other hand, the slowly mobile sofa back of the body, when moving chi fully be attached to the sofa back (the mobile backward 1mm of the horizontal pipe that is connected with sensor apart from the time-----attached: scale is arranged), with adjustable screw fixed lateral pipe.
4, with institute's angle measurement degree zero clearing, close display power supply then, unclamp adjustable screw, make horizontal pipe reduction, gently move on one side.
5, behind the sofa durability experiment, protecting under the carrier strip spare,, repeat above-mentioned 3 operation in same measuring point, measured angles of display is back of the body shake allowance (after the measurement can not zero clearing); Unclamp adjustable screw, make the transverse pipe reduction.
6, under sofa unloading situation, in same measuring point, repeat above-mentioned 3 operation, measured angles of display is back of the body residue shake allowance; Unclamp adjustable screw, make horizontal pipe reduction.
7, close display, measure and finish.
