[0001] The utility model relates to the technical field of electronic scales, and more specifically, to a portable electronic scale. Background Art
[0002] Electronic scales are a type of weighing instrument. They are tools that use Hooke's law or the principle of lever balance of force to measure the mass of an object. They are widely used in people's daily lives, bringing great convenience to businesses, families and individuals.
[0003] When using an existing electronic scale, the electronic scale is first placed on the ground, and then the object to be weighed is placed on the scale pan. The weight of the object is then transferred to the indicating system through a force transfer system, and the weight of the object can be checked.
[0004] However, when electronic scales are actually used, in order to ensure the accuracy of weighing items, the four legs at the bottom of the electronic scale are generally placed on the same placement surface. When the placement surface is uneven and one of the legs is on the concave surface, the leg is easily affected by the gravity of the electronic scale itself and will tilt downward, causing the electronic scale to shake repeatedly, affecting the accuracy of weighing items. Utility Model Content

[0023] Example
[0024] Refer to the instruction manual Figure 1-Figure 6 A portable electronic scale comprises a weighing body 6, a weighing pan 4, and a box bottom plate 1. The weighing body 6 is connected to the box bottom plate 1 through the weighing pan 4. A display screen 7 is arranged on the surface of the weighing body 6. The bottom surface of the weighing body 6 is detachably mounted on the surface of the weighing pan 4 through screws. A level 5 is fixedly arranged on the surface of the weighing pan 4.
[0025] An adjustment component is commonly provided between the weighing pan 4 and the box bottom plate 1, and the adjustment component includes a screw rod 8 and a rotating drum 10. A connecting sleeve 9 is fixedly provided on the top of the screw rod 8, and the connecting sleeve 9 is fixedly connected to the bottom of the weighing pan 4 by screws. A rotating drum 10 is threadedly provided on the bottom of the screw rod 8, and the rotating drum 10 is rotatably connected to the surface of the box bottom plate 1.
[0026] It should be noted that when the box bottom plate 1 is placed on an uneven placement point, the box bottom plate 1 is first placed face down to increase the contact area with the placement point through the box bottom plate 1, and the box bottom plate 1 is adjusted to a suitable position so that it no longer shakes. Then the box bottom plate 1 is opened and the level 5 is observed. When the level 5 shows that the horizontal line is uneven, the height of either side of the bottom of the weighing pan 4 can be adjusted by rotating the contact distance between the end of the screw 8 that needs to be adjusted and the inner cavity of the rotating drum 10. When the indicator needle of the level 5 shows that it is horizontal, stop. Then place the object to be weighed on the surface of the weighing body 6, and the measurement value can be monitored by observing the display screen 7.
[0027] Furthermore, a limiting assembly is provided in the inner cavity at the bottom of the rotating drum 10, and the limiting assembly includes a telescopic rod 15 arranged in the inner cavity of the rotating drum 10, and a spring 16 is sleeved on the outside of the telescopic rod 15, and L-shaped limiting blocks 13 are connected to both ends of the telescopic rod 15 and the spring 16, and a pressing block 12 is fixedly provided on the side of the L-shaped limiting block 13 away from the telescopic rod 15, and the outer ends of the pressing block 12 and the L-shaped limiting block 13 both pass through the rotating drum 10 and are slidably connected to the rotating drum 10; limiting grooves are provided at positions on the surface of the box bottom plate 1 corresponding to the rotating drum 10, and the rotating drum 10 is detachably connected to the box bottom plate 1 through the L-shaped limiting block 13.
[0028] In the above embodiment, when the bottom of the rotating drum 10 is installed on the surface of the box bottom plate 1, the bottom of the rotating drum 10 can push the L-shaped limit block 13 outward through the elasticity of the spring 16 itself, so that the bottom of the rotating drum 10 can be engaged with the limit groove opened on the surface of the box bottom plate 1, thereby realizing the function of installing the weighing body 6 on the surface of the box bottom plate 1. By pressing the pressing block 12 inward, the L-shaped limit blocks 13 can be close to each other, which can facilitate the separation of the rotating drum 10 from the box bottom plate 1, and the weighing body 6 can be conveniently disassembled and installed on the surface of the box bottom plate 1, so as to adapt to different terrains, thereby effectively improving the practicality of the device.
[0029] Furthermore, a mounting ring 14 is fixedly sleeved outside the rotating drum 10 , and a plurality of triangular blocks 11 are evenly connected to the surface of the mounting ring 14 .
[0030] In the above embodiment, the mounting ring 14 can be rotated by moving the triangular block 11 , so that the mounting ring 14 drives the rotating drum 10 to rotate.
[0031] Furthermore, a box cover 2 is provided on the surface of the box bottom plate 1, and one side of the box bottom plate 1 and the box cover 2 are hinged.
[0032] In the above embodiment, when the weighing body 6 is not in use, the box bottom plate 1 and the box cover 2 are brought into contact so that the weighing body 6 is located inside the cavity formed between the box bottom plate 1 and the box cover 2. This can facilitate the storage of the weighing body 6 and prevent dust from accumulating on the surface of the weighing body 6 and from being squeezed and damaged when not in use, thereby affecting the service life of the weighing body 6.
[0033] Furthermore, handles 3 are provided on the surfaces of the box bottom plate 1 and the box cover 2 , and the handles 3 are provided on the side away from the hinged connection between the box bottom plate 1 and the box cover 2 .
[0034] In the above embodiment, when the box bottom plate 1 and the box cover 2 are closed, the box bottom plate 1 and the box cover 2 can be moved by pulling the handle 3, thereby realizing the function of conveniently carrying the weighing body 6.
[0035] In this embodiment, the implementation scenario is specifically as follows: when the device is placed on an uneven placement point, first place the bottom surface of the box bottom plate 1 downward, increase the contact area with the placement point through the box bottom plate 1, and adjust the box bottom plate 1 to be stably placed, then open the box bottom plate 1 and the box cover 2, and observe the level meter 5 at this time. When the level meter 5 shows that the horizontal line is uneven, by rotating the triangular block 11 on the side that needs to be adjusted, the rotation of the triangular block 11 drives the rotation of the rotating drum 10, and the contact distance between the end of the screw rod 8 and the inner cavity of the rotating drum 10 can be adjusted to adjust the height of any side of the bottom of the weighing pan 4. When the indicator needle of the level meter 5 shows that it is horizontal, stop, then place the object to be weighed on the surface of the weighing body 6, and monitor the measurement value by observing the display screen 7;
[0036] When the weighing body 6 is used, the box cover 2 and the box bottom plate 1 are closed to complete the storage of the weighing body 6, and the weighing body 6 can be conveniently carried by pulling the handle 3.
[0037] Finally: The above description is only a preferred embodiment of the present utility model and is not intended to limit the present utility model. Any modifications, equivalent substitutions, improvements, etc. made within the spirit and principles of the present utility model should be included in the protection scope of the present utility model.
