The utility model will be described in detail by embodiment below.

The utility model provides a kind of weight beam, and as Figure 1-4, the dynamometer is by dynamometer panel 1, link 2nd, the composition of hook 3.Link 2 is in circular ring type, is connected to the top of dynamometer panel 1, for hanging dynamometer, material can be metal, Wooden or resin.Hook 3 is connected with positioning sliding block 12, the bottom of dynamometer panel 1 is extended downward into, for hanging determinand Body, material can be metal, wooden or resin.

As shown in Figure 1-2, the middle part of dynamometer panel 1 is provided with the slider track 15 of strip, bearing of trend for from top to bottom, A part for the slider track 15 is in the front of dynamometer panel 1 by hollow out, formation slider track window 151, the slider track Window 151 includes track window upper end 1511, track window lower end 1512, and the slider track 15 can be the track in an imagination, An it can also be provided that entity track with rail walls.Positioning sliding block 12 is equipped with slider track 15, positioning is slided Block 12 can be observed by the positive slider track window 151 of dynamometer panel 1 by user, the upper end of positioning sliding block 12 with Spring 13 is connected, and lower end is connected with hook 3, and the spring 13 is fixed on the dorsal part upper end of dynamometer panel 1.When tangling weight, or During under tension, the traction positioning sliding block 12 of hook 3 slides in slider track 15, and the displacement of positioning sliding block 12 causes spring 13 to send out Raw deformation, when the elastic force of spring 13 is with weight when being equal in weight or be equal with pulling force, positioning sliding block 12 is still in slider track 15 a certain position.The both sides of slider track window 151 are respectively arranged with dynamometry dynamometric scale 11, dynamometer length scale 17, When dynamometer does not hang weight, the lower end of positioning sliding block 12 is correspondingly identified as 0 graduation mark.The dynamometry dynamometric scale 11 indicates When positioning sliding block 12 is static, the size of its stress, that is, when positioning sliding block 12 is static, dynamometry dynamometric corresponding to its lower end is carved The numerical value of degree 11；The dynamometer length scale 17 indicate positioning sliding block 12 it is static when, the size of spring deformation degree, that is, When positioning sliding block 12 is static, the numerical value of dynamometer length scale 17, is arranged such corresponding to its lower end, and user can be made more straight That sees observes spring force and the relation of its deformation.The back side of dynamometer panel 1, relative under track window lower end 1512 Portion, is provided with slide block limiting plate 16, and the slide block limiting plate 16 is extended in slider track 15 from the side of dynamometer panel 1, The position-limiting action to positioning sliding block 12 is played, when preventing hook 3 by excessive pulling force, causes spring 13 that inelastic deformation occurs, Cause the failure of dynamometer.The slide block limiting plate 16 can set two, extend respectively from the both sides at the back side of dynamometer panel 1 To slider track 15.Preferably, the upper strata of slide block limiting plate 16 can set cushion pad 161, using flexible material such as Cotton, rubber etc. are made, and play the cushioning effect to positioning sliding block 12, prevent the breakage of positioning sliding block 12.

As Figure 1-3, in the dynamometer panel 1 be fitted together to have level meter 14, for check dynamometer whether be in The vertical state of horizontal direction, ensure the accuracy of measurement.The level meter 14 can also be bonded in dynamometer panel 1 just Face, but with the growth of usage time, it is possible that situations such as bonding does not cause tightly level meter 14 to come off or shift.The water Liquid is marked with level 14, the liquid can be purified water, oil or other organic or inorganic solvents, preferably purified water.Institute The dorsal part of level meter 14 is stated, is provided with liquid injection port 142, the fluid injection lid being matched therewith is provided with liquid injection port 142, works as level meter In 14 liquid reduce when, can in the case where not dismantling level meter 14, by liquid injection port 142 into level meter conveniently Feeding-in liquid, while can also avoid thering is temperature difference to cause the inwall of level meter 14 to be had inside and outside level meter 14 by opening liquid injection port The situation of water smoke.On dynamometer panel 1, on the position corresponding to the side of level meter 14 1, horizontal scale 143 is provided with, when When liquid level is concordant with horizontal scale 143/parallel in level meter 14, illustrate that dynamometer body is in the position with horizontal plane. Preferably, in the dorsal part of dynamometer panel 1, corresponding to the upper and lower side of level meter 14 on position, level meter dismounting groove 144 is provided with, just In the dismounting or replacing of level meter 14.

As shown in Figure 1, Figure 4, Figure 5, the link 2 is in circular ring type, is suspended on peg 4, is connected by link connecting rod 23 The top of dynamometer panel 1 is connected on, set screw 21 is provided with the link connecting rod 23, is set inside the link connecting rod 23 Locating dowel 22 is equipped with, when tightening set screw 21, the locating dowel 22 inside link connecting rod 23 is stretched out upwards, is adjusted when unscrewing During screw 21, the locating dowel 22 inside link connecting rod 23 reclaims downwards.In use, dynamometer is hung on peg 4, water is observed The internal liquid level of level 14, when liquid level is concordant with horizontal scale 143/parallel, tightening set screw 21 stretches out locating dowel 22, directly Peg 4 is held out against to it, plays and dynamometer is fixed, the effect for preventing it from rocking.After measurement, unscrew set screw 21, from Dynamometer is removed on peg 4.

It should be pointed out that for the person of ordinary skill of the art, on the premise of the utility model principle is not departed from, Some improvement and modification can also be carried out to the utility model, these are improved and modification also falls into the utility model claims In protection domain.
