Description
Technical Field
[0001] The utility model relates to the technical field of balances, in particular to a shock-absorbing balance. Background Technique
[0002] A balance, a weighing instrument, forms two arms with the fulcrum (axis) supporting the balance beam at the center of the beam. A pan is hung on each arm. An object with a known mass is placed in one pan, and the object to be measured is placed in the other pan. The deflection of the pointer fixed on the beam when it does not swing and points to the central scale indicates the mass of the object to be measured. A balance is an equal-arm lever. A balance is a weighing instrument for measuring the mass of an object. Some balances have very strict requirements for precision. Therefore, it is necessary to reduce the influence of external environmental vibrations on the balance. Thus, a shock-absorbing balance is proposed to solve the above problems.

DETAILED DESCRIPTION OF THE EMBODIMENTS
[0018] The technical solutions in the embodiments of the present utility model will be clearly and completely described below with reference to the accompanying drawings in the embodiments of the present utility model. Obviously, the described embodiments are only a part of the embodiments of the present utility model, rather than all the embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative efforts shall fall within the protection scope of the present utility model.

A shock-absorbing installation groove 2 is provided at the bottom end of the balance base 1. A shock-absorbing block 3 is arranged inside the shock-absorbing installation groove 2. Three positioning anchor rods 4 are fixedly connected inside the shock-absorbing installation groove 2. A column 5 is fixedly connected to the top end of the balance base 1. A balance vertical block 6 is fixedly connected to the top end of the column 5. A balance groove 7 is provided on the balance vertical block 6. A balance top pin 8 is arranged inside the balance groove 7. A balance arm 9 is fixedly connected to the top end of the balance top pin 8. Suspension mechanisms 10 are hung at both the left and right ends of the balance arm 9. Leveling bolts 11 are threadedly connected to both the left and right ends of the balance arm 9. A pointer 12 is fixedly connected to the bottom end of the balance arm 9. A scale plate 13 is fixedly connected to the front end of the column 5;

One ends of the plurality of shock-absorbing springs are all in contact with the shock-absorbing installation groove 2, and the plurality of shock-absorbing springs do not contact each other.
[0021] With the above settings, first, the entire device is fixed on the experimental table (there are positioning grooves on the experimental table that are adapted to the three positioning anchor rods 4) through the three positioning anchor rods 4. Then, the leveling bolts 11 are rotated to keep the suspension mechanisms 10 at both the left and right ends of the balance arm 9 in balance. Then, a test object is added to the right suspension mechanism 10, and weights are added to the left suspension mechanism 10. Observe the reading of the scale plate 13 corresponding to the deflection of the pointer 12. Combine the gram number of the weights with the reading of the pointer 12 on the scale plate 13 to determine the weight of the test object. It should be noted that the plurality of shock-absorbing springs are distributed vertically and horizontally in the sponge, which can absorb the vibrations of the entire device in all directions, thereby reducing the vibrations received by the entire device and enhancing the earthquake resistance of the entire device.
