Embodiment

[0020] Such as figure 1 As shown, a magnetic suction seat device for an anti-loosening acceleration sensor, including

[0021] metal shell 5;

[0022] The permanent magnet 4 is fixed on the metal casing 5;

[0023] Bolt 1, its bottom is arranged on the metal casing, and its head passes through the metal casing 5 and is connected with the acceleration sensor;

[0024] The elastic washer 2 is sleeved on the bolt 1;

[0025] The spacer 3 is arranged between the bolt 1 and the permanent magnet 4 .

[0026] The metal casing 5 is provided with a groove for fixing the permanent magnet and a screw hole for bolt penetration. The permanent magnet 4 is fixed in the groove of the metal casing by glue. The elastic washer 2 is sleeved on the bolt 1 and tightly connected with the metal casing. The isolating spacer 3 acts as isolating glue to prevent the glue from adhering to the bolt.

[0027] Such as figure 2 As shown, the acceleration sensor a and the magnetic seat device b are fi...

Abstract

The invention relates to a looseness-preventing acceleration sensor magnetic suction base device. The looseness-preventing acceleration sensor magnetic suction base device comprises a metal outer shell, a permanent magnet fixed to the metal outer shell, a bolt and an elastic washer, wherein the bottom of the bolt is arranged on the metal outer shell, the head of the bolt penetrates through the metal outer shell to be connected with an acceleration sensor, and the elastic washer is arranged on the bolt in a sleeving mode. Compared with the prior art, the looseness-preventing acceleration sensor magnetic suction base device has the advantages that the vibration conduction effectiveness of a detected object is improved, and the measurement result accuracy of the acceleration sensor is guaranteed.

Description

technical field [0001] The invention relates to an acceleration sensor fixing device, in particular to an anti-loosening acceleration sensor magnetic suction seat device. Background technique [0002] At present, common methods for installing the acceleration sensor include: bolt connection, adhesive connection and magnetic adsorption connection. Wherein, the magnet adsorption connection is convenient to use. However, the magnet (magnetic seat) and the acceleration sensor are connected by bolts, and the connection is fixed by the friction force of the thread, which is easily disengaged by the vibration of the measured object, resulting in inaccurate measured values. Contents of the invention [0003] The object of the present invention is to provide a magnetic suction seat device for an anti-loosening acceleration sensor in order to overcome the above-mentioned defects in the prior art. [0004] The purpose of the present invention can be achieved through the following t...
