[0033] Example 1

[0034] like Figures 1-4 This embodiment provides an electronic scale with an easily replaceable tray, comprising: a scale assembly 1; a load cell 2, one end of which is connected to the scale assembly 1; a connecting seat 3 with two slots 31, one end of which is connected to the other end of the load cell 2; a tray 4 with two insert plates 41, the insert plates 41 and the slots 31 being movably fitted; a push rod 5 with an annular groove 51, the push rod 5 being movably located within the connecting seat 3; two locking rods 6, both movably located within the connecting seat 3, one end of each locking rod 6 abutting against the two insert plates 41; and a ball 7 abutting between the other end of the two locking rods 6 and the annular groove 51.

[0035] Specifically, during installation, firstly, the two insert plates 41 of the tray 4 are inserted into the two slots 31 of the connecting seat 3 to facilitate the horizontal positioning of the tray 4; then, one end of the push rod 5 is pushed, and under the action of the inner wall of the annular groove 51 of the push rod 5, the ball 7 moves upward, so that the ball 7 and the other ends of the two locking rods 6 are in contact, thereby causing the ball 7 to push open the two locking rods 6, and finally causing one end of the two locking rods 6 to contact the two insert plates 41 to complete the locking, which facilitates the vertical positioning of the tray 4.

[0036] During disassembly, first, push the other end of the push rod 5, and under the action of gravity, the ball 7 falls to the lowest point of the annular groove 51; finally, lift the tray 4 upward to separate the two insert plates 41 of the tray 4 from the two slots 31 of the connecting seat 3, thereby completing the disassembly.

[0037] In summary, this solution facilitates the assembly and disassembly of the tray 4 through the slot 31, insert plate 41, push rod 5, locking rod 6, and ball 7, thereby making it easy to replace trays 4 of different sizes to fit objects of different volumes and ensuring good replaceability of the tray 4.

[0038] Furthermore, such as Figures 3-4 It also includes two rotating blocks 8 located on both sides of the push rod 5, and the rotating blocks 8 are threaded into the connecting seat 3.

[0039] Specifically, the threaded connection facilitates good locking performance between the rotating block 8 and the connecting seat 3, thereby ensuring good locking performance of the push rod 5, the ball 7 and the locking rod 6, and also facilitates improving the pushing accuracy of the rotating block 8.

[0040] Furthermore, such as Figure 3 It also includes a mating groove 81 located at the end of the rotating block 8 away from the push rod 5.

[0041] Specifically, the mating groove 81 is used to mate with the relevant wrench. The mating groove 81 is an embedded structure, which helps to reduce the volume of the electronic scale with easy tray replacement in this solution. The shape of the mating groove 81 can be an internal hexagon, an internal triangle, etc.

[0042] Or, such as Figure 4 It also includes a handle 82 connected to the end of the rotating block 8 away from the push rod 5, and the handle 82 is located outside the connecting seat 3.

[0043] Specifically, the handle 82 facilitates the easy pushing of the rotating block 8 without the need for additional tools.

[0044] Furthermore, such as Figure 2 The insert plate 41 is connected to a ramp 42, which is inclined and protrudes towards the locking rod 6.

[0045] Specifically, during operation, the locking rod 6 provides a vertical limit to the ramp 42, making it easier for the ramp 42 to further prevent the insert plate 41 and the slot 31 from separating from each other; during disassembly, the ramp 42 pushes the locking rod 6 and the ball 7 in sequence, making it easier for the ball 7 to return to the lowest point of the annular groove 51.

[0046] Furthermore, such as Figure 2 The two slots 31 are arranged symmetrically about the connecting seat 3, and the two insert plates 41 are arranged symmetrically about the tray 4.

[0047] Specifically, the axisymmetric design facilitates good force symmetry in the insert plate 41.

[0048] Furthermore, such as Figure 1 The scale assembly 1 includes: a scale body 11, one end of a weighing sensor 2 connected to the scale body 11; a controller; a display 12, a battery, and a button unit 13 all electrically connected to the controller; wherein the controller, the display 12, the battery, and the button unit 13 are all connected to the scale body 11.

[0049] Specifically, the scale body 11 is used to carry the controller, display 12, battery, and button unit 13, etc.; the controller is used for control; the display 12 is used to display the weight of the object; the battery is used for power supply; the button unit 13 is used for tare, switch, and change the weight display unit, etc. It should be noted that since the weight of the tray 4 of different sizes is different, tare is required after changing the tray 4 and before weighing.

[0050] Furthermore, such as Figure 1 The weighing sensor 2 is in the form of a strain gauge.

[0051] Specifically, the strain gauge design makes the weighing sensor 2 more accurate and has a wider measurement range.

[0052] The above embodiments only illustrate several implementation methods of this utility model, and their descriptions are relatively specific and detailed, but they should not be construed as limiting the scope of this utility model patent. It should be noted that those skilled in the art can make various modifications and improvements without departing from the concept of this utility model, and these all fall within the protection scope of this utility model. Therefore, the protection scope of this utility model patent should be determined by the appended claims.
