A weighing system comprises the weighing sensor assembly.
The working principle of the invention is as follows: when weighing, an object is placed on the weighing platform 6, the weight of the object presses down the weighing platform 6, and then gravity acts on the weighing sensor 7, so that the weight of the object can be directly obtained.
The ground cannot be guaranteed to be horizontal during weighing, the weighing platform 6 is prone to cause inaccurate weighing when inclined, the self-adaptive adjustment can be performed when the ground faces uneven ground, the reference object shown in fig. 2 is taken as a reference object, wherein the left and right directions are the central axis direction of a rotating shaft II 5 shown in fig. 2, the front and back directions are the central axis direction of a rotating shaft I3 shown in fig. 2, when the inclined ground appears in the left and right directions, the base 1 is inclined, the conical weight 8 is hung at the bottom of the support frame II 4, because the central line of the conical weight 8 always points to the horizontal plane, and the conical weight 8 has a certain weight, the support frame II 4 has an acting force keeping the horizontal state, because the base 1 is inclined, the support frame II 4 has an acting force keeping the horizontal state, and the support frame I2 is rotatably installed relative to the base 1, therefore, the support frame I2 for mounting the support frame II 4 rotates relative to the base 1, and the support frame II 4 can be kept in a horizontal state. If the ground is inclined in the front-back direction shown in the attached drawing 2, the support frame II 4 is inclined relative to the support frame I2, and therefore the support frame II 4 is guaranteed to be in a horizontal state. Therefore, the support frame II 4 can be kept in a horizontal state when facing the ground with different inclined planes, the self-adaptive adjustment effect is realized, and the condition that the weighing effect is influenced due to the inclination of the weighing platform 6 is avoided.
After the self-adaptive level adjustment, the rotating shaft I3 and the rotating shaft II 5 are locked through the locking assembly 9, specifically, the two-way screw rod 912 is rotated, so that the two sliding blocks 913 move towards the mutually approaching direction, therefore, the two clamping rings I92 are mutually closed and clamp the rotating shaft II 5, the slope surfaces of the two slope-shaped pressing blocks 95 are in contact with the clamping ring II 93, the clamping ring II 93 is pressed downwards, and the rotating shaft I3 is clamped by the clamping ring II 93 to realize locking.
Because locking subassembly 9 sets up on support frame I2, consequently snap ring I92 can reach the effect of locking with II 5 contacts of pivot all the time when support frame I2 is relative base 1 and is rotated.
The height of the feet 12 relative to the support bar 11 can be adjusted so that the feet 12 in contact with the ground can adapt to different levelling conditions.
