The present invention has a shape of a dish indicating scale, and part of the structure relates to a ring market manual scale which is a combination of the dish indicating scale and the plate manual scale structure.

A scale is a weighing instrument for measuring the load of an object to be weighed. The scales commonly used in our daily life include dish indicating scales and plate manual scales.

The dish indicator scale receives the load of the weighed object on the plate from two or less load pedestals, and converts the load received from the load pedestal into the linear motion of the rack by means of springs and transducers, and the pinion with the guide fixed to the rack. The pinion rotates according to the up and down motion of the rack and rotates the guide so that the guide indicates the scale or value corresponding to the load of the weighed object. Because of its small size and simple structure, it is manufactured by limiting the maximum mass to 50kg or less and is used by many households, rural or merchants.

The manual scale receives the loads of the weighed objects on the plate from three or more load pedestals, equalizes and equalizes the loads of the measured masses at a constant mass ratio, and transfers the momentum corresponding to the matched mass to the load payload rods. The load transmitted to the center is the weight that is lifted from the center bar to get balance with the target, so that the weight of the target is measured first, and the weight of the remaining weight is moved from the scale to the weight of the target. It is a meter that measures the load of the measured object by summing the value measured in the secondary load and the value measured in the vertebrae. It is possible to improve a large weight (50 to 1000 kg) because the structure is large and precise.

However, in the rural area, crops that are harvested and weighed in containers are large and heavy (greater than 50 kg). Therefore, in order to measure such heavy items, plate manual scales capable of weighing 50 kg to 1000 kg should be used. It is.

Although the manual scale of the plate is large in appearance and precise in internal structure, it has the advantage of being able to weigh from 50kg to 1000kg, but it is too expensive to manufacture and the weight of the measured object is moved by moving the chute to keep the scale horizontal. Due to the complexity of the weighing methods, they were not widely distributed in rural areas.

The present invention is to change the structure of the "plate" of the "plate" of the dish indicating scale, to receive the load of the weighed object placed on the "plate" at four points, the load received at the four points from the lever In order to balance with the measured object by increasing the ratio, it is transferred to the load transmission structure similar to the structure of the plate directing plate, and the up and down movement of the lever is converted to the rotational movement of the roller so that the instruction indicates the correct weight. Therefore, the purpose of the present invention is to provide a scale that is about the same shape and size as a dish indicating scale, but also combines a part of the structure of a plate manual scale to weigh more than 50kg up to 1000kg and simplify the use and weighing method. .

Hereinafter, a specific embodiment for solving the above object is described according to the accompanying drawings. (In this design, "L" is given to the parts on the left and "R" for the parts on the right, based on the weighing display for easy understanding. Does not give)

The ring commercial manual scale of the present invention is configured to distribute the load by receiving a load placed on the body portion 1 on which each component is fixed, a loading portion 2 on which an object to be weighed, and a loading portion 2 are loaded. The load transmitting portion K, the guide rotating portion 8 for converting the load received from the load transmitting portion K into the rotational movement, and the guide rotating portion receiving the rotating movement of the guide rotating portion 8 It is provided with a metering indicator 9 for directing the indicator to indicate a numerical value or scale corresponding to the load placed on the loading part 2 by the rotation of the guide, and between the load transmission part K and the guide pivoting part 8.

Cover 94 to protect weighing indicator 9.

In the present invention, the scale 92 and the numerical value 93 are displayed on the scale plate 91 with the outer surface (the maximum mass that can be measured without using the weight) as 10 kg. have.

As described above with reference to FIGS. 7 and 8 will be described the load transfer process and the method of weighing when measuring the weighed object by using the cardboard scale of the present invention configured as described above.

When the weighted object is placed on the load loading part 2, that is, the loading plate 21, and then the weights are stacked on the pivot table 614 to obtain a balance with the weighted object, the blood load is applied to the four load receiving bases 31. The load of the metered material is distributed and transmitted, and the load transmitted to the load receiving stand 31 is transmitted to the lever 33 through the pedestal 32, the middle plate 34, and the middle plate 331.

When the load is transmitted to the lever 33, the lever 33 moves downward toward the point piece 332 and the point plate 35, that is, in the direction of arrow A, and is connected to the left and right fixed to the lever 33. The plates 37L and 37R move in the direction of arrow B together with the lever 33. At this time, the load transmitted to the short-term (41) is transmitted to the lower long-term 42 through the connecting plate fixture 411, the connecting plate 43 and the connecting piece 421, the load transmitted to the left load bracket (31L, 31L) And the loads transmitted to the right load pedestals 31R and 31R are matched at the lower side organs 42 so that the organ 42 moves in the direction of arrow B together with the left and right connecting plates 37L and 37L.

As the lower side organ 42 moves in the direction of arrow B, one side end of the upper side organ 45 connected to one side tip of the lower side organ 42 and the middle plate 44 moves in the direction of arrow C and the upper side organ 45 is moved. The other side of the point piece 521 and the point plate 53 to move to the upper side, that is, the arrow D direction.

At this time, the load transmitted to the upper organ (45) is first weighed by a weight (not shown) mounted on the weight bar 614, the spring 64 is elongated in accordance with the mass ratio of the weight remaining by weighing by the weight The upper organ 45 is to move in the direction of the arrow D.

According to this momentum, when the compensator 7 connected to the one end of the upper organ 45 moves in the direction of the arrow E, the lever 88 connected to the bimetal 75 of the compensator 7 is the lever base 89. The side connected with the bimetal 75 moves in the direction of arrow F as shown in FIG. 7B, and the other side moves in the direction of arrow G, so that the roller drive plate 86 wound around the roller 84 is moved in the direction of arrow H. Pulled.

The roller 84 moves by the roller drive plate 86 in the direction of arrow I in the roller insertion groove 831 of the inclined plate 83, and the driving shaft 850 formed on the side of the roller 84 is guided to the guide plate 851. And rolling the upper side of the inclined plate 83 to rotate the guide (P) fixed to the drive shaft (85) to weigh in the center and the weight of the remaining measured object is indicated by the value and the guide (P) measured in the center You just add the values together.

Ring commercial manual scale according to the present invention as described above receives the load at the four points of the loading portion (2) on which the measurement object is placed and transferred to the extension 61 to the center of the load transmitted to the extension 61 In the same way as the plate manual balance, the configuration indicating the load on the weight of the remaining weight after weighing firstly at the center and weighing at the central part is similar to the plate manual balance. It is similar to the indicator scale, and it is not possible to measure it on a dish indicator scale, that is, it can measure up to 50 kg up to 50 kg, and by rotating the guide (P) for the rolling motion of the roller, not the rack and pinion configuration, It is possible to precisely weigh the weight of the object, and it is convenient to package the price in a certain packing unit (weight) by directing the instruction (P) to directly measure the remaining load after weighing at the center. It is very beneficial and convenient for anti-markets and especially for weighing agricultural products.
