[0016] In order to make the technical means, creative features, objectives and effects achieved by the present invention easy to understand, the present invention is further described below in conjunction with specific implementation methods.

[0017] like Figure 1-Figure 3 As shown, a sensing structure of a weighing plate includes a weighing plate 1, with magnetic pads 2 fixedly installed at the center of the upper and lower ends of the weighing plate 1 and near the four corners, a metal adapter 4 is installed at the bottom of the magnetic pad 2, and the outer rings of the four metal adapters 4 are provided with the same bracket 5 near the bottom, and a strain type weighing sensor 6 is fixedly installed at the center of the bottom of the bracket 5.

[0018] A bottom plate 7 is fixedly mounted on the bottom end of the strain type weighing sensor 6, and a buffer bracket 3 is mounted on the bottom of the bottom plate 7 by bolts. The bottom plate 7 and the bolts are provided to facilitate disassembly and installation of the buffer bracket 3.

[0019] The thickness of the magnetic pad 2 is equal to half the thickness of the weighing plate 1. The metal adapter 4 is magnetically connected to the magnetic pad 2. The metal adapter 4 is snap-fitted to the weighing plate 1. By setting the magnetic connection between the metal adapter 4 and the magnetic pad 2, the installation and disassembly of the metal adapter 4 is facilitated.

[0020] The metal adapter 4 is magnetically connected to the magnetic sleeve 8 , so that the weighing plate 1 and the bracket 5 can be connected via the metal adapter 4 .

[0021] The main cross-section of the buffer bracket 3 is set in a bridge shape. The bridge-shaped buffer bracket 3 provides buffering. When the weight on the top of the weighing plate 1 exceeds the load of the strain type weighing sensor 6, the buffer bracket 3 deforms to provide buffering, thereby preventing the strain type weighing sensor 6 from being overloaded and damaged.

[0022] It should be noted that the utility model is a sensor structure of a weighing plate. When in use, firstly, according to the depth of the electronic scale box, a metal adapter 4 of a suitable height is selected, then the buffer bracket 3 is installed inside the electronic scale box through an external bolt, and then the metal adapter 4 is inserted into the magnetic sleeve 8, and then the weighing plate 1 is clamped to the top of the metal adapter 4, so that the metal adapter 4 is magnetically connected to the magnetic pad 2;

[0023] During weighing, the object is placed on the top of the magnetic pad 2, and the weight borne by the weighing plate 1 is transmitted to the strain type weighing sensor 6 through the bracket 5, causing the deformation of the strain type weighing sensor 6. The signal of the strain type weighing sensor 6 is transmitted to the corresponding electrical element in the electronic scale box, and the weighing information is displayed on the display screen after the signal conversion;

[0024] When the strain type weighing sensor 6 is deformed by force, the force is transmitted to the buffer bracket 3. When the weight exceeds the load of the strain type weighing sensor 6, the buffer bracket 3 is deformed to provide buffering, thereby preventing the strain type weighing sensor 6 from being overloaded and damaged.

[0025] The above shows and describes the basic principle and main features of the utility model and the advantages of the utility model. Those skilled in the art should understand that the utility model is not limited by the above embodiments. The above embodiments and descriptions are only for explaining the principle of the utility model. Without departing from the spirit and scope of the utility model, the utility model may have various changes and improvements, which fall within the scope of the utility model to be protected.
