A force transmission conversion frame is installed on the top side of the electronic scale body. Screws are fixed at both ends of the top side of the barcode electronic scale body. A sliding bracket is slidingly sleeved on the screw. Limit arms are fixed on both sides of the sliding bracket. When the electronic scale is in use, the weighing plate is placed on the top side of the force transmission conversion frame.

[0022] As shown in Figure 3 The connecting mechanism comprises a sleeve 9, the top end of the sleeve 9 is provided with a hole and slidably inserted with a limiting rod 10, the top end of the limiting rod 10 is fixed with a rubber pad 11, the bottom end of the limiting rod 10 is fixed with a limiting cap 12, the top side of the support table 2 is fixed with the sleeve 9 at four corners, the limiting cap 12 and the inner top end of the sleeve 9 are fixedly connected with a spring 13, the inner side of the sleeve 9 is slidably inserted with a hollow tube 14, the bottom end of the hollow tube 14 is fixed with a suction cup 15, and the suction cup 15 is located at the four corners of the bottom side of the support table 2;

[0023] When the fixing device structure is complex and inconvenient to use, the structure of the connecting mechanism is used to place the support table 2 on the top side of the weighing table 1, so that the suction cup 15 is in contact with the surface of the weighing table 1, at this time the support table 2 is lowered until the cylinder 3 is in contact with the surface of the weighing table 1, the suction cup 15 drives the hollow tube 14 to shrink to the inner side of the sleeve 9, the limiting rod 10 is pulled to make the air in the inner side of the sleeve 9 exhaust, then the limiting rod 10 is loosened, the limiting cap 12 is pushed down by the spring 13, and the limiting rod 10 drives the rubber pad 11 to seal the top side of the sleeve 9, so as to make the suction cup 15 adsorbed and fixed on the surface of the weighing table 1, when disassembled, the inner side of the sleeve 9 is communicated with the external environment by pulling the limiting rod 10, so that the support table 2 can be removed, so as to be more convenient for the operator to use.

[0026] The working principle of this utility model is:

[0027] Electronic scales are commonly used weighing equipment in commercial and industrial places. They are widely used in supermarkets, markets, medicine, food processing and other fields. Electronic scales usually have the characteristics of high precision, strong reliability and good durability, so that they can meet the weighing accuracy and efficiency requirements of different industries. During the use of existing electronic scales, if the object to be weighed is spherical, the object is easy to move and collide inside the weighing pan during the weighing process, making it inconvenient to weigh it, resulting in reduced weighing accuracy of the device.

[0028] In order to solve this problem, a fixing mechanism and a connecting mechanism are set up, the positioning rod 20 is pulled out, and the limit plates 18 on both sides are pulled to make them extend and retract to the appropriate width, and then the positioning rod 20 is reinserted into the support platform 2 and the inner side of the positioning hole 19, and the slide plate 17 and the limit plate 18 are fixed so that the limit plates 18 are located on both sides of the weighing platform 1, and the support platform 2 is limited. Then the support platform 2 is placed on the top side of the weighing platform 1, and the suction cup 15 contacts the surface of the weighing platform 1. At this time, the support platform 2 drops until the cylinder 3 contacts the surface of the weighing platform 1, and the suction cup 15 drives the hollow tube 14 to shrink to the inside of the sleeve 9, and the limit rod 10 is pulled to discharge the air inside the sleeve 9, and then the limit rod 10 is released, and the spring 13 pushes the limit cap 12 to drop, prompting the limit rod 10 to drive The rubber pad 11 seals the top side of the sleeve 9, thereby prompting the suction cup 15 to be adsorbed and fixed on the surface of the weighing platform 1. When the object is placed on the surface of the support platform 2, the object is in contact with the round rod 8 and pushes the round rod 8 to retract to the inside of the cylinder 3, thereby driving the piston 5 to descend and compressing the air inside the cylinder 3. At this time, each round rod 8 is close to the bottom surface of the object, thereby preventing the object from being displaced during operation and affecting the accuracy of weighing. After weighing is completed, the object is removed. At this time, the compressed air inside the cylinder 3 pushes the piston 5 to rise and reset the round rod 8 so that the next object can be weighed. When it needs to be disassembled after use, pull the limit rod 10 to connect the inside of the sleeve 9 with the external environment, and the support platform 2 can be removed, which solves the problem of easy displacement of objects during weighing.
