[0027] The beneficial effects of the present invention are as follows:
[0028] First, the present application is provided with a plurality of the load cells, which are correspondingly fixed in a plurality of the clamping grooves, so as to be evenly arranged in a ring shape in the flat weighing body. In this way, when an item to be weighed is placed on the flat weighing body for weighing, the weighing of the item to be weighed will be more accurate and reliable. Since a plurality of the buffer foot supports are evenly arranged in a ring shape on the lower bottom surface of the flat weighing body, and the upper ends thereof correspondingly extend into the lower parts of a plurality of the clamping grooves, when the present application is placed on a tricycle or a four-wheeled vehicle used for picking up and delivering express parcels, or directly placed on a plane such as the ground or a tabletop, the flat weighing body of the present application will be elastically supported, so that it has good shock absorption performance, good anti-bumping effect and good anti-vibration effect during transportation or use, the service life of a plurality of electronic components such as the load cells used is long, and the overall operation of the present application is more stable and reliable, and the weighing data is also relatively accurate.

[0076] The portable logistics scale 1000 with a balance structure according to an embodiment of the present utility model will be described in detail below with reference to the accompanying drawings.
[0077] Refer to Figures 1 to 6 As shown, the portable logistics scale 1000 with a balance structure according to an embodiment of the present utility model includes a flat scale body 10, a weighing digital display device 20, a plurality of weighing sensors 30, and a plurality of pressure - reducing foot supports 40 with a balance function;
[0078] Among them, the weighing digital display device 20 is fixedly arranged in the flat scale body 10; a viewing window 101 for exposing the weighing digital display device 20 is opened on the upper end surface of the flat scale body 10 near its edge, and a plurality of clamping grooves are uniformly opened upward on the peripheral edge of the lower bottom surface of the flat scale body 10;
[0079] And, a plurality of the weighing sensors 30 are correspondingly fixedly arranged in the upper parts of the plurality of clamping grooves and are all connected to the weighing digital display device 20; a plurality of the pressure - reducing foot supports 40 are uniformly arranged in a ring on the lower bottom surface of the flat scale body 10, and their upper ends correspondingly extend into the lower parts of the plurality of clamping grooves.
[0080] Based on the above, it can be clearly seen that when the present application is specifically implemented, it is mainly used as a portable logistics scale 1000 with a balance structure.
[0081] Specifically, when applying the present application, after assembling the present application according to the above structure, the present application can be easily used. For example, carry the present application and place it on a tricycle or four-wheeled vehicle used for picking up and delivering express deliveries, or directly place it on the ground, tabletop, etc. For the use of the present application, it will obviously have the following technical effects:
[0082] On the one hand, the present application is provided with a plurality of the weighing sensors 30, which are correspondingly fixed in a plurality of the clamping grooves and are evenly arranged in a ring around the flat scale body 10. In this way, when placing an item to be weighed on the flat scale body 10 for weighing, the weighing of the item to be weighed will be more accurate and reliable.
[0083] On the other hand, since a plurality of the pressure relief foot supports 40 are evenly arranged in a ring around the lower bottom surface of the flat scale body 10 and their upper ends correspondingly extend into the lower parts of a plurality of the clamping grooves, when the present application is placed on a tricycle or four-wheeled vehicle used for picking up and delivering express deliveries, or directly placed on a flat surface such as the ground or tabletop, the flat scale body 10 of the present application will be elastically supported, so that it has good pressure relief performance, good anti-bumping effect and good anti-vibration effect during transportation or use, the service life of a plurality of electronic components such as the weighing sensors 30 used is long, and the overall operation of the present application is more stable and reliable, and the weighing data will also be relatively accurate.
[0084] Furthermore, through the above optimization design, the overall structure formed by the present application has strong practicability and good use effect.
[0085] Further, when specifically implemented, according to an embodiment of the present invention, the bottoms of a plurality of the pressure relief foot supports 40 are flush with each other to stably lift the flat scale body 10.
[0086] In this regard, it can be clearly seen that the present application is preferably placed on a relatively flat platform or the like to weigh an item. When the present application is placed on an uneven platform or the like to weigh an item, a plurality of the pressure relief foot supports 40 can automatically level according to the height difference, so that the present application can be placed as stably as possible, with extremely excellent balance effect and better weighing accuracy.
[0087] Still further, when specifically implemented, according to an embodiment of the present invention, a grip groove 102 penetrating from the upper end surface of the flat scale body 10 to its lower bottom surface is provided near the edge of the upper end surface of the flat scale body 10.
[0088] Thus, by pinching the holding groove 102 by hand, the user can easily carry the present application for transportation, making the present application convenient to carry.
[0089] In addition, in specific implementation, referring to Figure 2 and Figure 4 shown, according to an embodiment of the present invention, the present application further includes a speaker 50 connected to the weighing digital display device 20 through an audio output circuit for broadcasting the weighing result;
[0090] Wherein, a speaker fixing position 103 is provided inside the flat weighing body 10, and the speaker 50 is detachably fixed to the speaker fixing position 103; an sound amplification hole 104 facing the speaker 50 is opened on the lower bottom surface of the flat weighing body 10.
[0091] Obviously, the present application is equipped with the speaker 50 for broadcasting the weighing result, so that the weighing data is output through voice, which can make it more prominent for the user and others to know.
[0092] It should be noted here that the function of the weighing scale with voice broadcasting belongs to the existing mature technology, so the specific circuit details and the like will not be elaborated here.
[0093] Furthermore, in specific implementation, continuing to refer to Figure 2 and Figure 4 shown, according to an embodiment of the present invention, the present application further includes a rechargeable battery 60 connected to the weighing digital display device 20 for supplying power to the weighing digital display device 20;
[0094] Wherein, a battery fixing position 105 is provided inside the flat weighing body 10, and the rechargeable battery 60 is detachably fixed to the battery fixing position 105.
[0095] Thus, it can be clear that the present application is equipped with the rechargeable battery 60 to supply power to electronic components such as the weighing digital display device 20, so that the external power cord can be omitted during use, making it more convenient and convenient to use.
[0096] Again, on the basis of the above embodiment, referring to Figure 1 , Figure 2 , Figure 3 and Figure 4 shown, according to an embodiment of the present invention, the present application further includes a charging interface 70 connected to the rechargeable battery 60 through a battery charging protection circuit;
[0097] Wherein, a plugging slot is opened on the side surface of the flat weighing body 10, the charging interface 70 is arranged on the weighing digital display device 20 and is adapted to be clamped to the plugging slot, and a switchable sealing plug 106 for sealing the charging interface 70 is provided at the plugging slot.
[0098] Therefore, when the rechargeable battery 60 is about to run out of power or is completely out of power, the openable and closable sealing plug 106 can be opened, and the rechargeable battery 60 can be charged by an external power supply through the charging interface 70, so that the present application can be used uninterruptedly. When the charging interface 70 is not in use, the openable and closable sealing plug 106 can be closed to seal the charging interface 70, so as to better prevent water from entering it.
[0099] Preferably, in this technical solution, Figure 2 and Figure 4 As shown, according to one embodiment of the utility model, the flat scale body 10 includes a bottom shell 10a and a weighing surface cover 10b fixed together by fastening bolts;
[0100] The upper end surface of the weighing cover 10b is concave downward near its edge to form an avoidance groove 10b1, the bottom of the avoidance groove 10b1 is provided with a corresponding viewing window 101 to expose the weighing digital display device 20, and the side of the weighing cover 10b is provided with the plug-in groove.
[0101] In this regard, it is clear that when the items to be weighed are placed on the upper end surface of the weighing surface cover 10b, the avoidance groove 10b1 is provided for overhead avoidance, so that the items to be weighed can avoid pressing the weighing digital display device 20 exposed at the viewing window 101 as much as possible, making the weighing digital display device 20 more stable and reliable to use and not easy to be crushed.
[0102] Furthermore, in the specific implementation, it is still necessary to refer to Figure 2 and Figure 4 As shown, according to an embodiment of the present utility model, each of the pressure relief foot supports 40 comprises an upper isolation block 401, a pressure relief spring 402 and a lower support block 403 which are arranged in sequence from top to bottom;
[0103] Among them, a plurality of movable grooves 10a1 are evenly opened upward on the circumference of the lower bottom surface of the bottom shell 10a, and each of the movable grooves 10a1 has a limiting ring 10a2 extending to the upper part of the inner bottom surface of the bottom shell 10a; a plurality of fixed grooves 10b2 are evenly protruded downward on the circumference of the inner top surface of the weighing surface cover 10b, and the plurality of fixed grooves 10b2 are correspondingly located directly above the plurality of limiting rings 10a2; the relative positions of the fixed grooves 10b2 and the movable grooves 10a1 constitute the card-mounting groove.
[0104] In addition, the multiple weighing sensors 30 are correspondingly mounted in the multiple fixed grooves 10b2, and their bottoms are correspondingly abutted against the upper end surfaces of the multiple upper isolation blocks 401; the multiple lower support blocks 403 are correspondingly mounted in the multiple limit rings 10a2 so as to be movable up and down, and their bottoms extend out of the lower parts of the multiple movable grooves 10a1.
[0105] Therefore, it is clear that when the present application is in use, the plurality of pressure-relief springs 402 are used for pressure relief, so as to elastically support the flat scale body 10 to prevent it from being bumped and vibrated during transportation or use as much as possible.
[0106] And in this technical solution, the control Figure 2 , Figure 4 , Figure 5 and Figure 6 As shown, according to an embodiment of the present utility model, a plurality of inverted L-shaped limit buckles 10a3 are evenly arranged upward on the inner bottom surface of the bottom shell 10a at the periphery of each limit ring 10a2, and the upper ends of each group of the inverted L-shaped limit buckles 10a3 point to the axis of the limit ring 10a2 at the corresponding position;
[0107] Among them, the peripheral edges of the multiple upper isolation blocks 401 are correspondingly fixed in the upper ends of the multiple inverted L-shaped limit buckles 10a3 at corresponding positions, and the peripheral edges of the upper end surfaces thereof are correspondingly abutted against the inner top surfaces of the multiple inverted L-shaped limit buckles 10a3 at corresponding positions.
[0108] In this regard, it is clear that:
[0109] On the one hand, the present application is placed on the ground, tabletop or other flat surfaces to weigh items. Before weighing, no matter how the multiple pressure-relieving foot supports 40 are subjected to the reaction force of the ground, tabletop or other flat surfaces, their upper ends will always be limited in height, that is, the peripheral edges of the upper end surfaces of the multiple upper isolation blocks 401 will always correspond to the inner top surfaces of the multiple inverted L-shaped limit buckles 10a3 at the corresponding positions, so that no force will be generated on the multiple weighing sensors 30, so that the multiple weighing sensors 30 will not be damaged by being pressed upward for a long time.
[0110] On the other hand, when using the present application, the items to be weighed are placed on the upper end surface of the weighing surface cover 10b, and the downward pressure generated will act on the multiple weighing sensors 30 to obtain weighing data through the multiple weighing sensors 30 and display it through the weighing digital display device 20.
[0111] Preferably, in the technical solution, according to an embodiment of the present invention, a upper snap ring 4011 adapted to be snapped into the upper end of the buffer spring 402 is convexly provided downward in the middle of the lower bottom surface of each of the upper isolation blocks 401; a lower card slot 4031 adapted to be movably snapped into the lower end of the buffer spring 402 and the upper snap ring 4011 is respectively opened downward in the middle of the upper end surface of each of the lower support blocks 403, and an anti - detachment outer edge 4032 is respectively convexly provided outward on the upper part of each of the lower support blocks 403.
[0112] Initially, a plurality of the buffer springs 402 are in a natural state or a compressed state, and a plurality of the anti - detachment outer edges 4032 are correspondingly supported by the upper edges of a plurality of the limiting rings 10a2.
[0113] Thus, it can be clearly understood that when the present application is in use, the upper and lower ends of a plurality of the buffer springs 402 can be preferably limited in the upper snap ring 4011 and the lower card slot 4031 correspondingly. At the same time, when the upper snap ring 4011 is also limited in the lower card slot 4031, the buffer foot support 40 of the present application moves stably and reliably in the up - down direction and is not prone to circumferential displacement.
[0114] Moreover, when a plurality of the anti - detachment outer edges 4032 are correspondingly supported by the upper edges of a plurality of the limiting rings 10a2, the plurality of buffer foot supports 40 of the present application are also firmly fixed and not prone to slipping and falling off.
[0115] It should be added that in specific implementation, according to the portable logistics scale 1000 with a balance structure provided by the embodiment of the present invention, each of the buffer foot supports 40 further includes a soft rubber pad 404 fixed on the lower bottom surface of the lower support block 403. In this way, when the whole structure of the present application is placed on a plane such as the ground or a tabletop, the buffering performance is better and more excellent, the anti - bump impact force is better and more excellent, and the service life is longer.
[0116] Other embodiments, etc., are not illustrated herein by way of example.
[0117] In summary, the present application is provided with a plurality of the weighing sensors 30, which are correspondingly fixed in the plurality of the card-mounting slots, so that they are evenly arranged in the flat scale body 10. In this way, even when the items to be weighed are placed on the flat scale body 10 for weighing, the weighing of the items to be weighed will be more accurate and reliable. Since the plurality of the pressure-relieving foot supports 40 are evenly arranged in the lower bottom surface of the flat scale body 10, and their upper ends extend into the lower parts of the plurality of the card-mounting slots, in this way, even when the present application is placed on a tricycle or four-wheel vehicle used for picking up and delivering express, or directly placed on a flat surface such as the ground or a desktop, the flat scale body 10 of the present application will be elastically supported, so that it has good pressure-relieving performance, good anti-bumping effect and good anti-vibration effect during transportation or use, so that the electronic components such as the plurality of the weighing sensors 30 used have a long service life, and the overall operation of the present application is more stable and reliable, and the weighing data will be relatively accurate.
[0118] Furthermore, even when the present application is placed on an uneven platform or the like to weigh items, the plurality of pressure-relieving foot supports 40 can automatically level the present application according to the height difference, so that the present application can be placed as stably as possible, resulting in an excellent balancing effect. Moreover, the user can easily carry the present application for transportation by pinching the grip groove 102, making the present application easy to carry.
[0119] In addition, the present application has its own speaker 50 for broadcasting the weighing results, so that the weighing data can be output through voice, which can be more prominently known to the user. The present application has its own rechargeable battery 60 to power the electronic components such as the weighing digital display device 20, so that the external power cord can be omitted during use, making it more convenient to use.
[0120] Furthermore, when the items to be weighed are placed on the upper end surface of the weighing surface cover 10b, the avoidance groove 10b1 is provided to avoid the items to be weighed from pressing the weighing digital display device 20 exposed at the viewing window 101 as much as possible, making the weighing digital display device 20 more stable and reliable to use and not easy to be crushed.
[0121] Again, place the present application on a flat surface such as the ground or a tabletop to weigh an object. Before weighing, no matter how the multiple pressure-relieving foot supports 40 are affected by the reaction force of the flat surface such as the ground or a tabletop, their upper ends will always be limited in height position. That is, the peripheries of the upper end faces of the multiple upper isolation blocks 401 will always correspondingly abut against the inner top surfaces of the multiple inverted L-shaped limit buckles 10a3 at corresponding positions, so that no force will be generated on the multiple load cells 30, and the multiple load cells 30 will not be damaged by being continuously pressed upwards for a long time. When using the present application, place the object to be weighed on the upper end face of the weighing surface cover 10b, and the generated downward pressure will act on the multiple load cells 30, so as to obtain weighing data through the multiple load cells 30 and display it through the weighing digital display device 20, making the present application very reliable in use.
[0122] Furthermore, the portable logistics scale 1000 with a balance structure provided by the present application is indeed extremely practical and has excellent use effects, making the present application necessarily have good market promotion value. The present application will also surely be very popular and can be effectively popularized.
