[embodiment]
The utility model is a kind of hanging spring balance, it includes the scale body of being made up of fore shell 101 and bonnet 102 1, on this fore shell 101, be provided with dial plate 2, in this scale body 1, be provided with the spring adjustable plate 3 that connects successively, metering spring 4, pull bar link 5 and pull bar 6, below pull bar 6, be provided with and be used for the hook 7 of weighing, the top of spring adjustable plate 3 is connected with balancing controls 8 on being arranged on scale body 1, be connected with tooth bar 9 in the middle of pull bar link 5 tops, tooth bar 9 rotates by the gear 10 driven gear axles 11 that are meshed with it, gear shaft 11 1 ends stretch out the back from fore shell 101 and dial plate 2 and are connected with the value pointer 12 in dial plate 2 the place aheads, for realizing that two total indicator readings improve the precision of weighing, on this pull bar link 5, also be provided with connecting rod 13, the other end of connecting rod 13 is connected with fork 14, fork 14 can drive the fork axle 15 that is located in the scale body 1 and rotate, and fork axle 15 stretches out the back from fore shell 101 and dial plate 2 and is connected with the second value pointer 16 in dial plate 2 the place aheads.Pull bar link 5, pull bar 6 and link up with 7 and form drag link mechanisms, connecting rod 13, fork 14, fork axle 15 and the second value pointer 16 are formed the second value gear train.
In the present embodiment, the value pointer 12 that will be connected with gear shaft 11 is decided to be gram metering pointer, and the second value pointer 16 that is connected with fork axle 15 is decided to be kilogram metering pointer.During weighing, on hook 7, hang up weighing article, hook 7 drives pull bar link 5 by pull bar 6 and moves downward, metering spring 4 stressed stretchings, at this moment, the tooth bar 9 that is connected with pull bar link 5 also and then moves downward, and then by tooth bar 9 and the gear 10 that is meshed gear shaft 11 is rotated, thereby drive gram metering pointer and rotate the gram number (g) of scale thing for reading; When the weight of institute's scale thing exceeded the full-scale reading of value pointer 12, value pointer 12 had rotated a circle, and 16 displacements of the second value pointer just overlap with value pointer 12.When equivalent value pointer 12 is rotated further the rotation full scale that promptly carries out second circle, the full angle of the second value pointer, 16 row, the kilogram number (kg) of scale thing for reading, the weight of institute's scale is more accurate like this, can be as accurate as the gram position.
Less for ease of weighing, light and inconvenience hangs over the object on the hook 7, can load onto the batching dish 17 of this object of splendid attire below pull bar 6.In the present embodiment, have groove 601 in pull bar 6 lower ends, this groove 601 can coil 17 card ear 171 clampings with batching.At this moment, when weighing, take out standby batching dish 17 and the groove 601 that the card ear on it 171 is aimed on the pull bars 6 just can be loaded onto batching dish 17, institute's scale thing can be put in the batching dish 17 weighing like this.
In embodiment as shown in Figure 1, metering spring 4 has two, and these two metering springs 4 lay respectively at the two ends of spring adjustable plate 3 and pull bar link 5 and are connected with them.The vertical section of pull bar link 5 be the type under shed shape (as shown in Figure 2), it can certainly be the upward opening shape, have a breach 501 at these pull bar link 5 upper end sides, when mounted, connecting rod 13 1 ends are hinged by the steel axle 18 in the axis hole 502 of these breach 501 backs and pull bar link 5 side elevations, Zheng Ti structure is compact like this, can save the space of installation, thereby can do the hanging spring balance smallerly.
The upper and lower part of hook 7 is respectively hangers 71 and a hook 72 downward, upper shed, and hangers 71 lays respectively at the relative both sides of hook coupler body with hook 72; Pull bar 6 is a hollow tube, has the storage tank 602 that is used for placing hook 7 below pull bar 6, is used for putting the hanging scroll 19 of hook 7 when being provided with weighing in this storage tank 602; Described storage tank 602 roughly is the J type, in this J type storage tank and the groove that is arranged in hanging scroll 19 opposite sides the projection 603 that the hook 7 prevent storage tank 602 drops is set, link up with at 7 o'clock in collection, this projection 603 can just be kept off slot 721 places at hook 72 inwalls.Maybe need not link up with 7 weighings and when adopting batching to coil 17 weighings in collection at ordinary times, just whole hook 7 can be ensconced in the storage tank 602 of pull bar 6, at this moment the projection 603 in the storage tank 602 is just kept off and is sentenced anti-whole hook 7 at the slot 721 of hook 72 and drop out storage tank 602, and the hook in the storage tank 602 7 can not be installed in the groove 601 of pull bar 6 by overslaugh batching dish 17.When using hook 7 the time, it is pulled down, dropping on the hanging scroll 19 up to the hangers 71 under shed is available to have come weighing.
