Description

Technical Field

[0001] This utility model belongs to the field of intelligent equipment technology, specifically relating to an installation structure for an intelligent cabinet weighing sensor. Background Technology

[0002] The weighing sensor of the smart cabinet is the core component used to detect changes in the weight of items in the smart cabinet system. By converting physical weight into electrical signals, it enables real-time monitoring and management of inventory status and the retrieval and placement of items. The installation structure of the weighing sensor of the smart cabinet needs to be designed according to the cabinet type (such as vertical, hanging or horizontal) and the usage scenario. The core objective is to ensure that the sensor is stably subjected to force and to avoid lateral force interference.

[0003] The existing intelligent cabinet weighing sensors have insufficient installation accuracy. Traditional installation methods rely on manual adjustment, which makes it difficult to ensure that the sensor is horizontally and evenly stressed, resulting in measurement errors and reducing the effectiveness of use. To address this, we propose an installation structure for intelligent cabinet weighing sensors. Utility Model Content

[0004] The purpose of this utility model is to provide an installation structure for a smart cabinet weighing sensor to solve the problems mentioned in the background art.

[0005] To achieve the above objectives, this utility model provides the following technical solution: an installation structure for a smart cabinet weighing sensor, comprising a base plate, a first positioning hole on the surface of the base plate, a weighing sensor disposed on the surface of the base plate, a mounting hole on one side of the surface of the weighing sensor, a first bolt threadedly fixed between the first positioning hole and the mounting hole, a fixing hole on one side of the surface of the weighing sensor, a pressure point disposed inside the fixing hole, a steel ball abutting above the pressure point, a pressure cap abutting the top of the steel ball, a support plate connected above the pressure cap, connecting holes distributed at the four corners of the surface of the support plate, a second positioning hole on one side of the surface of the base plate, a limit bolt threadedly fixed between one side of the support plate and the second positioning hole, and a connecting end fixedly installed at one end of the weighing sensor.

[0006] Preferably, a connecting block is fixedly installed at each of the four corners of the base plate, a second bolt is vertically slidably passed through the surface of the connecting block, a support pad is rotatably connected to the bottom end of the second bolt, an adjusting nut is rotatably installed on the surface of the connecting block, and the second bolt and the adjusting nut are connected by a threaded rotatable connection.

[0007] Preferably, a horizontal bubble device is embedded in one side of the surface of the base plate.

[0008] Preferably, a washer is slidably fitted onto the surface of the first bolt.

[0009] Preferably, the base plate has pre-drilled holes at each of its four corners.

[0010] Preferably, a groove is provided on the surface of the support plate at the position where it contacts the limiting bolt.

[0011] Compared with the prior art, the beneficial effects of this utility model are:

[0012] 1. The pressure cap ensures uniform force transmission, the steel ball can compensate for displacement caused by environmental factors (such as temperature), and the pressure point restricts forces in non-vertical directions, which not only improves the anti-interference ability of the weighing sensor, but also extends its service life.

[0013] 2. By rotating the adjusting nut, the second bolt and the support pad can be raised and lowered. In conjunction with the set level bubble device, the overall level of the base plate can be adjusted, further improving the measurement accuracy of the device. Attached Figure Description
