Abstract
The utility model relates to a double-pointer metering and indication spring scale. The double-pointer metering and indication spring scale is composed of two double-connecting gears, a fixing plate, a hollow gear, and two pointers. After racks and the double-connecting gears are engaged and connected, another double-connecting gear and the hollow gear are engaged and connected, and the two pointers can rotate on a dial by the same shaft core. The rotation angle of one pointer (which is used for representing grams) is greater than the rotation angle of the other pointer (which is used for showing kilograms) under the action of the transmitting ratio of the double-connecting gears, and thereby, the metering precision of the double-pointer metering and indication spring scale is enhanced. The utility model has the characteristics of simple and reasonable structure, high metering precision, and convenient and practical use.
Description
The utility model relates to the spring balance of a kind of pair of pointer metering indication.
At present, portable spring scale commonly used, mainly be partly to constitute by spring, gear, tooth bar and pointer etc., gear rotates on index dial by tooth bar transmission drive pointer during use, thereby demonstrate the weight of weighing article body, because the diameter of index dial is less, so that scale is very close and have only a root pointer.Its weak point is the delicate value that is not easily distinguishable out, and metering precision is poor.
The purpose of this utility model is exactly that the spring balance that a kind of pair of pointer indicated, the accuracy of measuring is high is provided in order to overcome above-mentioned weak point.
The utility model comprises spring, tooth bar, parts such as gear and pointer, its objective is and realize by following scheme: the utility model is the coaxial two-gang gear (1 that is made of big pinion wheel, 2), fixed head 3, hollow wheel gear 4 and pointer (5,6) form, the pinion wheel of duplicate gear 1 and tooth bar 7 are connected with a joggle, the gear wheel of the pinion wheel of duplicate gear 2 and duplicate gear 1 is connected with a joggle, the gear wheel of duplicate gear 2 then is connected with a joggle with hollow wheel gear 4, fixed head 3 has the cylinder ring 9 of protrusion identical with axis hole 10 and axial line, fixed head 3 is fixed on the support 8 and cylinder ring 9 is embedded in the inner chamber of hollow wheel gear 4, pass hollow wheel gear 4 behind the axis hole 10 of the rotating shaft of duplicate gear 1 by fixed head 3 and be connected with pointer 6, an end of hollow wheel gear 4 is connected with pointer 5.The fixed shaft hole of the rotating shaft of duplicate gear 2 on support 8 11 li can flexible plate 12.
The utility model will be further described below in conjunction with accompanying drawing:
Fig. 1 is a structural representation of the present utility model.
Fig. 2 is an A-A cross-sectional view of the present utility model.
Fig. 3 is a fixed head cross-sectional view of the present utility model.
Fig. 4 is a fixed shaft hole B-B cross-sectional view of the present utility model.
Referring to Fig. 1～Fig. 4, pointer 6 of the present utility model directly is connected with the rotating shaft of duplicate gear 1, pointer 5 then is connected with the rotating shaft of hollow wheel gear 4, tooth bar 7 is connected with the pinion of duplicate gear 1, when tooth bar 7 moves up and down, duplicate gear (1,2) and hollow wheel gear 4 are rotated simultaneously, because the effect of duplicate gear (1,2) ratio of gear, the rotational angle that makes hollow wheel gear 4 is greater than duplicate gear 1, thereby improved measuring accuracy.The cylinder ring 9 of fixed head 3 and axis hole 10 are fixed the rotating shaft of duplicate gear 1 and the inner chamber of hollow wheel gear 4.The axis hole 11 that duplicate gear 2 is installed is arranged on support 8, and a slot 13 across fixed shaft hole 11 arranged, can 11 li elastic panel 12 be housed at fixed shaft hole by slot 13, make duplicate gear 2 be close to duplicate gear 1, improve the accuracy of measuring thereby reduce drive gap.When using the utility model, by weight tooth bar 7 is moved with weighed object, drive the rotation of duplicate gear (1,2) and hollow wheel gear 4, and pointer (5,6) is rotated on index dial, pointer 6 can be used for the expression kilogram, pointer 5 can be used for the expression gram, thereby reaches the purpose that improves the accuracy of measuring.
In like manner the utility model also can be used for other spring balance such as desk-top, suspension type, just can further improve measuring accuracy if increase duplicate gear, fixed head and a pointer again.
Characteristics of the present utility model are: simple in structure, the measuring accuracy height can make portable Scale does smaller and more exquisitely, practical.
Claims (3)
