Sensor fixing device and electronic scale

Abstract

The utility model discloses a sensor fixing device and an electronic scale, the sensor fixing device comprises a mounting base, a cover body and a plug connector, the cover body is provided with two oppositely arranged limiting protrusions, and the limiting protrusions wrap at least one corner of a sensor; the plug connector can be switched between a first position and a second position through horizontal movement, one end of the plug connector penetrates through the cover body to be exposed outwards, and after the plug connector horizontally moves from the first position to the second position, the plug connector moves in the direction close to the limiting protrusion so as to abut against the sensor. According to the sensor fixing device, the cover body can be fixed by moving the plug connector from the first position to the second position, connection can be achieved without fasteners such as bolts and screws, and the assembly difficulty and the production cost of the sensor fixing device are reduced.

Claims

1. A sensor fixing device, characterized in that: include: A mounting base (1), wherein the mounting base (1) is used to mount a sensor (4); A cover body (2), the cover body (2) being mounted on the mounting base (1), the cover body (2) being provided with two oppositely arranged limiting protrusions (21), the limiting protrusions (21) surrounding at least one corner of the sensor (4); A connector (3) is movably mounted on the cover body (2); the connector (3) can be switched between a first position and a second position by horizontal movement; when the connector (3) is in the first position, a gap exists between the side of the connector (3) facing the limiting protrusion (21) and the sensor (4); when the connector (3) is in the second position, the side of the connector (3) facing the limiting protrusion (21) contacts the sensor (4) so ​​that the connector (3) cooperates with the limiting protrusion (21) to fix the sensor (4).

2. A sensor fixing device as claimed in claim 1, characterized in that: An annular limiting portion (11) and a support platform (12) located inside the annular limiting portion (11) are arranged inside the mounting base (1), and the annular limiting portion (11) is surrounded to form a receiving cavity (111); the sensor (4) is embedded in the receiving cavity (111), and at least a part of the sensor (4) is in contact with the support platform (12).

3.
