Description

Technical Field

[0001] This utility model relates to the field of electronic balances, and in particular to a general-purpose balance structure. Background Technology

[0002] Electronic balances are instruments used to weigh objects, generally employing strain gauge sensors, capacitive sensors, or electromagnetic balance sensors. They are characterized by accurate and reliable weighing, rapid and clear display, and the presence of automatic detection systems, simple automatic calibration devices, and overload protection. The weighing pan has a critical impact on the weighing accuracy. The structure of the weighing pan can be referenced in Chinese Utility Model Patent Application No. CN202021317790.3, entitled "A Laboratory Electronic Balance." While the weighing pan is mostly fixed, in some applications, a rotating structure is necessary for accurate weighing. Existing balances cannot flexibly switch between these two modes, causing inconvenience during use. Utility Model Content

[0006] The sensor body is set inside the balance body and connected to the mounting base;

[0007] The weighing pan body has a positioning post and a mounting groove at the bottom. The positioning post is rotatably connected to the positioning hole, and the mounting groove has a detachable locking post that is plugged into the locking groove.

[0008] Furthermore, the mounting base and the mounting hole are fitted with a clearance fit, and the mounting base is supported on the sensor body.

[0009] Furthermore, the mounting groove is provided with internal threads, and the locking post is provided with external threads that connect with the internal threads.

[0010] Furthermore, two or more mounting slots are evenly arranged around the positioning post in the circumferential direction.

[0011] Furthermore, the top surface of the weighing pan body is provided with an extension locking hole.

[0012] Furthermore, two or more extension locking holes are spaced apart along the circumferential direction on the top edge of the weighing pan body.

[0013] Furthermore, the main body of the weighing pan includes a hollow weighing pan and a solid weighing pan stacked together, with positioning posts and mounting grooves located at the bottom of the hollow weighing pan.

[0014] Furthermore, the top surface of the hollow weighing pan is provided with a positioning groove, and the bottom surface of the solid weighing pan is provided with a positioning boss that engages with the positioning groove.

[0015] Furthermore, the balance body is equipped with a dust cover, which is placed over the weighing pan.

[0016] Furthermore, the dust cover is detachably connected to the main body of the balance.

[0017] The beneficial effects of this utility model are as follows: A universal balance structure is provided, with mounting holes designed on the balance body to accommodate a mounting base. The mounting base has positioning holes for positioning the weighing pan body and locking grooves for locking the weighing pan body. A locking pin is installed in the mounting groove of the weighing pan body, and the positioning pin of the weighing pan body is inserted into the positioning hole. After the locking pin is inserted into the locking groove, the weighing pan is in a fixed, non-rotatable state. The locking pin is removed from the mounting groove of the weighing pan body, and the positioning pin of the weighing pan body is inserted into the positioning hole, allowing the weighing pan to rotate. The universal balance structure provided by this utility model allows the weighing pan to switch between fixed and rotating modes, offering good versatility and a wide range of applications.
