Description

Technical Field

[0001] The utility model relates to the technical field of sensor installation, in particular to a sensor installation kit. Background Art

[0002] Mettler-Toledo Co., Ltd. applied for patent number CN201210349792.4 in 2012, entitled "Dynamometer Weighing Module" invention patent, part of which is shown in the following diagram: Figure 7-Figure 11 shown.

[0003] The technical solution of this patent has the following deficiencies: Figure 7 As shown in the figure, in order to bear the large vertical load, the 120 feature is added, which increases the manufacturing cost and the welding difficulty. In addition, the layout position of the 121 feature is limited due to the need for the 120 feature. In addition, in order to add the 120 feature, it can only be designed into a simple trapezoidal structure, which has limited contribution to improving the vertical force resistance. Ultimately, this structural form has a weak ability to bear vertical loads, increases the manufacturing cost, increases the welding difficulty, and also affects the layout of other structures.

[0004] like Figure 8 and Fig. 9 As shown, the features 430 / 230 correspond to the sensorless and sensored states respectively. Due to the different states and the lack of the jack function, the operation is more complicated. Figure 8 and Fig.10 As shown, it is inconvenient to remove 442 in actual operation. When replacing the sensor, 442 needs to be inserted again, which is also inconvenient. Therefore, the technical solution of this patent does not have a jack function, which makes it inconvenient to remove the pad and makes it inconvenient to repair and replace the sensor.

[0005] In addition, if Fig.11 As shown, due to the use of 237 and ensuring the circumferential clearance, only redundant positioning parts can be designed to ensure the positioning of 206 in the absence of sensors, which increases the cost of parts. Utility Model Content
