The base 100, the shell of the sensor 200, the shell 300 and the weighing pan 400 are detachably connected together through a quick-release assembly 600. The utility model can realize the rapid disassembly and assembly of the electronic balance through the quick-release assembly 600, which is convenient for realizing the rapid disassembly and maintenance of the components inside the electronic balance after failure, and the operation is more convenient and efficient, which solves the problem that most traditional electronic balances use multiple screws to connect and fix various parts. When the components inside the electronic balance fail, the disassembly and assembly operations after maintenance are relatively cumbersome, which increases the unnecessary strength of the maintenance personnel and reduces the maintenance and replacement efficiency.

[0023] According to one embodiment of the utility model, Figure 1-3As shown, the quick-release assembly 600 includes a hand-tightening bolt 601 inserted into the through hole 500, and a nut 602 is threadedly connected to the hand-tightening bolt 601. A limiting groove 603 for limiting the nut 602 is provided on the weighing plate and on the axis of the through hole 500. The utility model can separate the hand-tightening bolt 601 from the nut 602 by twisting the hand-tightening bolt 601 and the limiting effect of the limiting groove 603 on the nut 602. Then the operator pulls the hand-tightening bolt 601 out of the through hole 500 inside the base 100, and then the maintenance person grasps the shell 300 and lifts it upwards, so as to realize the efficient and fast separation and disassembly operation of the shell 300 and the base 100, and the operation is more efficient and convenient.

[0024] According to another embodiment of the present invention, Figure 1 and Figure 2 As shown, a dust cover 700 is buckled in the limit groove 603, and the dust cover 700 should be made of plastic. The utility model can be inserted into the through hole 500 on the base 100 of the assembled electronic balance by a bolt until it passes through the limit groove 603 above the weighing plate, and then the nut 602 is tightened on the outside of the bolt, and then the dust cover 700 is inserted into the limit groove 603, so as to achieve the protection of the bolt and nut 602 in the limit groove 603, and prevent dust or moisture from entering the limit groove 603 and the through hole 500, causing the bolt and nut 602 to rust and then slip, thereby greatly improving the service life of the quick-release assembly 600.

[0025] According to another embodiment of the present invention, Figure 2 and Figure 3 As shown, the quick-release assembly 600 also includes a positioning pin hole 604 opened on the base 100 and a positioning pin rod 605 arranged on the inner wall of the shell 300 and adapted to the positioning pin hole 604. The utility model can realize a fast and efficient positioning and assembly operation of the base 100 and the shell 300 by aligning the positioning pin rod 605 on the shell 300 with the positioning pin hole 604 on the base 100 and inserting it, and the operation is more convenient.

[0026] The positioning pin hole 604 is a truncated cone structure with an upper opening larger than a lower opening, so as to facilitate the positioning pin rod 605 to be smoothly inserted into the positioning pin hole 604 .

[0027] The housing of the sensor 200 is detachably mounted on the base 100 via a clamping plate 800 and locking bolts, so as to facilitate the secure fixing and quick disassembly of the sensor 200.

[0028] The electronic balance further comprises a control panel 900 with a display screen. The control panel 900 is detachably arranged on the base 100 by means of locking screws, so as to facilitate the quick disassembly and installation of the control panel 900.

[0029] The use of the utility model:

[0030] First of all, it should be made clear that the electronic balance involved in the utility model is mainly used in places such as home, supermarket or convenience store, vegetable market, etc. Since supermarket or vegetable market need to be used frequently, it is easy for the internal parts of the electronic balance to be damaged frequently, which can better reflect its characteristics of quick disassembly and easy maintenance. The utility model takes the assembly and disassembly of the electronic balance as an example to explain its use method in detail. When it is necessary to disassemble the electronic balance, the operator stands up the side wall of the electronic balance and places it on the workbench, and then separates it from the nut 602 by twisting the hand-tightening bolt 601. Then the operator can separate the scale pan 400, the shell 300 and the base 100 in turn. Then the operator unscrews the locking bolt with the help of a screwdriver to realize the disassembly of the sensor 200. By unscrewing the locking screw, the disassembly of the control panel 900 can be realized, and the operation is more convenient. When it is necessary to assemble the repaired electronic balance, the operator only needs to grasp the shell 300 and move the positioning pin rod 605 on the shell 300 The locating pin hole 604 on the base 100 is aligned and inserted, and then the through hole 500 on the weighing pan is overlapped with the through hole 500 on the housing 300, and then the hand screw bolt 601 is inserted from the through hole 500 at the lower part of the base 100 until it conflicts with the nut 602 in the limiting groove 603. Then, the operator presses the dust cover 700 with one hand and tightens the hand screw bolt 601 with the other hand to realize the locking operation of the hand screw bolt 601 and the nut 602, thereby realizing the rapid assembly operation of the repaired electronic balance. The utility model can realize the rapid disassembly and assembly operation of the electronic balance through the quick-release component 600, which is convenient for realizing the rapid disassembly and maintenance operation of the components inside the electronic balance after failure, and the operation is more convenient and efficient, which solves the problem that most traditional electronic balances use multiple screws to connect and fix various parts. When the components inside the electronic balance fail, the disassembly and assembly operation after maintenance is relatively cumbersome, which increases the unnecessary strength of the maintenance personnel and reduces the maintenance and replacement efficiency.
