[0032] Example
[0033] like Figure 1-3 As shown, this embodiment provides an electronic scale weighing pan, including a pan body 11 and a plurality of legs 21, wherein the top of the pan body 11 is provided with an edge, and the plurality of legs 21 are rotatably mounted on both sides of the pan body 11, and a positioning arm 13 and a handle II 31 are movably mounted on the rear side of the pan body 11, and synchronous control arms 32 are fixedly mounted on both ends of the handle II 31, and the synchronous control arms 32 are rotatably connected to the middle positions of the plurality of legs 21 on both sides;
[0034] like Figure 3 As shown, the positioning arm 13 is slidably mounted on the side of the disk body 11 through a slider 14 , the lower side of the positioning arm 13 abuts against the outer side of the handle II 31 , and the handle I 15 is fixedly mounted on the positioning arm 13 .
[0035] When placing the object to be weighed on the upper side of the weighing pan of the electronic scale of this application:
[0036] Hold the handle Ⅰ15, control the positioning arm 13 to move downward relative to the disc body 11, and press the handle Ⅱ31, so that the two synchronous control arms 32 drive the multiple legs 21 to rotate synchronously. After the legs 21 abut against the ground, the disc body 11 is separated from the electronic scale; thereby, in the subsequent process of placing the objects to be weighed on the disc body 11, the vibration and impact that may be caused to the electronic scale can be effectively removed, avoiding mechanical damage to the precision electronic components inside the electronic scale, and ensuring the structural integrity and weighing accuracy of the electronic scale.
[0037] Among them, the top edge of the disk 11, the synchronous control arm 32 and the two legs 21 form a parallelogram mechanism, so that the disk 11 can be smoothly raised on the upper side of the electronic scale, and after rotating the legs 21, the disk 11 falls back smoothly to the upper side of the electronic scale.
[0038] When the bottoms of the multiple legs 21 are in contact with the ground, the legs 21 are in an inclined state, and the positioning arm 13 is locked at the side of the tray body 11 using fasteners. At this time, the positioning arm 13 serves to limit the handle II 31. The multiple legs 21 remain in an unfolded state, continuously supporting the tray body 11 on the ground, and have good stability in use.
[0039] In this embodiment, the positioning arm 13 and the handle II 31 are connected by magnetic adsorption coupling, so that the handle II 31 can be stably attached to the lower side of the positioning arm 13, and the multiple legs 21 are gathered on both sides of the disk body 11. Specifically: the positioning arm 13 and the handle II 31 are both provided with nylon iron boron magnets.
[0040] In order to ensure the convenience of movement of the disk body 11, Figure 1-2 As shown, a wheel frame 22 is rotatably installed at the bottom of the support leg 21, and a wheel is installed at one end of the wheel frame 22 located on the outside of the disc body 11. The disc body 11 is lifted on the ground by using multiple support legs 21, so that after the disc body 11 is separated from the electronic scale, the rotation of the wheel frame 22 allows the disc body 11 to move freely on the upper side of the electronic scale. When it is inconvenient to carry the electronic scale, the items to be weighed can be received and operated.
[0041] In order to ensure the storage effect of the multiple legs 21 with wheel frames 22, as Figure 1-2 and Figure 4 As shown, a bending end 33 is provided on the synchronous control arm 32. Under the action of the bending end 33, the synchronous control arm 32 and the wheel frame 22 will not collide, so that the support leg 21 with the wheel frame 22 can be completely folded on the side of the disc body 11, and the storage effect is good.
[0042] Example
[0043] The features of this embodiment that are the same as those of the first embodiment are not described in detail. The difference between this embodiment and the first embodiment is that: Figure 4-6 As shown, in this embodiment, the wheel frame 22 is slidably installed at the bottom of the support leg 21 along its own axial direction, a limiting protrusion 221 is provided at the other end of the wheel frame 22, and a limiting seat 16 is installed on the side of the disk body 11, and the limiting protrusion 221 is engaged with the recess 163 on the limiting seat 16; a tightening member 223 is installed between the support leg 21 and the wheel frame 22, and a limiting ring 222 for limiting the sliding of the wheel frame 22 is installed on the support leg 21.
[0044] By utilizing the elastic deformation of the pressing member 223 , the limiting protrusion 221 can be engaged and connected with the recess 163 , so that the plurality of legs 21 are gathered at both sides of the disk body 11 .
[0045] The tightening member 223 includes a spring and circular rings welded to both ends of the spring. The two circular rings are both sleeved and installed on the outside of the wheel frame 22. The two circular rings are respectively in contact with the support legs 21 and the wheel frame 22, so as not to affect the rotation of the wheel frame 22.
[0046] In order to facilitate the contact between the limiting protrusion 221 and the recess 163, as shown in FIG. Figure 6 As shown, a slide 161 and an arc edge 162 are provided on the limit seat 16, the slide 161 is connected to the lower end of the recess 163, and the arc edge 162 is provided at the bottom of the slide 161, and the slide 161 and the arc edge 162 are utilized to guide the movement of the limit protrusion 221, thereby improving the stability of the interlocking docking between the limit protrusion 221 and the recess 163.
