Abstract
The utility model relates to a machine protection device for an electronic balance (electronic scale) weighing machine. The device is arranged between a weighing supporting plate of an electronic balance (electronic scale) and a weighing sensor. A rotary knob is rotated to enhance a support plate at the time of non-weighing, non-loading, non-unloading or non-moving, the weighing supporting plate is caused to be separated from the weighing sensor, and the stress and the shock of the weighing sensor can be avoided. The rotary knob is rotated to lower the support plate at the time of weighing, the weighing supporting plate is combined with the weighing sensor, and work can be carried out. A protection device of the utility model has the advantages of simple structure and convenient operation, the utility model can be widely used for various electric balances (electric scales), weighing mechanisms can be effectively protected, service life is extended, and precision is kept.
Description
The present invention relates to the mechanical hook-up of a kind of protection electronic balance (electronic scales) weighing mechanism.
Electronic balance (electronic scales) is the requisite gauging instrument of industrial and agricultural production, scientific and technical research and teaching, also is the metering outfit of field of commercial circulation and people's daily life aspect.Weighing mechanism is the important process parts of electronic balance (electronic scales), its protection is being determined its work scope of application, work quality, measuring accuracy and serviceable life.
At present, the method for security protection that electronic balance (electronic scales) is adopted be the additional antioverloading protection mechanism of design on LOAD CELLS (Zhang Shixiang write " counter scale. platform balance. on-ground weigher " several counter scales commonly used of chapter 6. the structure of platform balance and on-ground weigher and performance, metering publishing house, May nineteen eighty-two; Yang Senping designs utility model patent " LOAD CELLS that has overcurrent protection structure ", the patent No.: ZL94238899.2).The LOAD CELLS that has overcurrent protection structure only is suitable for the application of resistance strain type sensor, additional spacing technological design on flexible member; Generally preventing to overload or impacting what cause that the excessive safety feature of LOAD CELLS displacement adopts is the design of control displacement limit point, and protective value is relatively poor.These devices make the design of LOAD CELLS and weighing mechanism and processing comparatively complicated; just passively when overload weighing or superpower impact occurring play their effects of not being damaged of protection; but weighing mechanism and LOAD CELLS still unavoidably are subjected to unnecessary load and impact; influence their work quality and degree of accuracy, and reduce serviceable life.
The objective of the invention is to design a kind of simple in structure, easy to operate, safe and reliable protection electronic balance (electronic scales) weighing mechanism and the mechanical hook-up of LOAD CELLS.Can be widely used on all kinds of electronic balances (electronic scales), increase the service life and keep precision.
The weighing protective device of electronic balance of the present invention (electronic scales) is made up of support plate, excentric shaft, upper and lower strut, rocking arm and knob etc.This weighing protective device is installed between large face plate and the LOAD CELLS, and two groups of excentric shafts are installed in parallel on the casing under the large face plate, and support plate is controlled lifting by excentric shaft, and rocking arm is handled by knob, drives upper and lower strut and makes excentric shaft do the rotations of 90 degree.When weighing is worked, rocking arm is gone to horizontality, driving up and down, two groups of connecting rods change the excentric shaft salient point over to horizontal level, make support plate fall to casing, large face plate combines with LOAD CELLS, the loading of tested material is passed to LOAD CELLS by large face plate, by LOAD CELLS measured signal is reflected on the display screen by processing of circuit again; When non-weighing state, loading and unloading or electronic balance (electronic scales) transfer are moved; rocking arm is turned to plumbness; drive two groups of connecting rods and change the excentric shaft salient point over to upright position; support plate is held up large face plate; isolate large face plate and LOAD CELLS; the effect of protection has been played in the influence that this moment, LOAD CELLS no longer arrived loading power and impulsive force.
The weighing protective device of this invention is installed between the large face plate and LOAD CELLS of electronic balance (electronic scales), and two groups of excentric shaft strands even are fixed on upper casing, and rocking shaft is fixed on the casing side, and two ends are installed rocking arm and knob respectively.
The advantage of the weighing protective device of electronic balance of the present invention (electronic scales) is: can protect weighing mechanism and LOAD CELLS effectively when non-weighing state, loading and unloading or electronic balance (electronic scales) are moved transfer; avoid being subjected to unnecessary load and impact; prolong the serviceable life of electronic balance (electronic scales), guarantee its work quality and precision.
The weighing protective device of electronic balance of the present invention (electronic scales) is provided by following examples and accompanying drawing thereof.
Fig. 1 is the structural representation of weighing protective device when weighing is worked of electronic balance of the present invention (electronic scales).
Fig. 2 is the structural representation of weighing protective device when protecting of electronic balance of the present invention (electronic scales).
Below in conjunction with Fig. 1, Fig. 2 to the detailed description of the invention.
The weighing protective device of electronic balance of the present invention (electronic scales) comprises large face plate 1, support plate 2, excentric shaft 3, even point 5, lower link 6, strand connect point 7, rocking arm 8, rocking shaft 9, LOAD CELLS 10, electronic balance (electronic scales) 11, knob 12 to go up connecting rod 4, strand.
Weighing when work be as shown in Figure 1: turning knob 12 is the level of state rocking arm 8, makes the parallel and casing of eccentric salient point of excentric shaft 3 by last connecting rod 4 and lower link 6, does not contact support plate 2, makes the support plate 2 disengaging large face plates 1 that fall; When loading force P effect and large face plate 1, large face plate 1 directly acts on weighing sensor 10 with power P, the output measuring-signal.
When protecting as shown in Figure 2: turning knob 12 makes rocking arm 8 in vertical state; the salient point that makes excentric shaft 3 by last connecting rod 4 and lower link 6 motions vertically upward; lift support plate 2 large face plate 1 is held up disengaging LOAD CELLS 10; play buffer action; when loading force or impulsive force P act on large face plate 1; LOAD CELLS 10 is because of isolating the effect that is not subjected to any power P, thereby realizes protection.
The weighing protective device of electronic balance of the present invention (electronic scales) also can supportingly need on the instrument or device of insulation blocking at some other.
