A Bluetooth communication module for torque wrench

Abstract

The invention provides a bluetooth communication module for a torque wrench, which includes a housing, a circuit board and a USB interface, the housing includes a mounting base and a cover, the circuit board is mounted on the mounting base, the The cover covers the installation base and seals the circuit board inside the housing; one end of the USB interface is electrically connected to the circuit board, and the other end extends through the installation base. out to the outside of the housing for connection with the torque wrench; the installation base is provided with a connecting piece fitted with the torque wrench. The bluetooth communication module of the present invention has a more compact structure and is more tightly bonded to the torque wrench, which can effectively avoid scratches. In addition, through the setting of the USB interface, it can be used for data communication on the one hand, and can be powered by the torque wrench on the other hand. Ensure that the battery life of the two is the same, and it is more convenient to use.

Description

technical field [0001] The invention relates to the technical field of digital tools, in particular to a Bluetooth communication module for a torque wrench. Background technique [0002] The Bluetooth communication module for the torque wrench transmits the information in the digital torque wrench through the Bluetooth module. [0003] The existing Bluetooth communication module for torque wrench has a large volume. When installed on a digital torque wrench, there will be a relatively large protrusion relative to the torque wrench. When working with a torque wrench, workers often need to use a lot of force, which is difficult and difficult. With fine control, it is easy for workers to scratch and damage the device during operation. Moreover, the storage of the digital torque wrench generally has a special bracket, and its large shape will also affect the convenience of storage. [0004] In addition, the existing bluetooth communication module generally uses a rechargeable ...

[0003] The existing Bluetooth communication module for torque wrench has a large volume. When installed on a digital torque wrench, there will be a relatively large protrusion relative to the torque wrench. When working with a torque wrench, workers often need to use a lot of force, which is difficult and difficult. Fine control, it is easy for workers to scratch and damage the device during operation

And the storage of digital torque wrench generally has a special bracket, and its large shape will also affect the convenience of storage

[0004] In addition, the existing Bluetooth communication modules generally use rechargeable batteries or dry batteries as independent power sources. When using them, it is necessary to ensure that the batteries have sufficient power. If there is no power, they cannot work normally.

Because it is an independent power supply, daily maintenance needs to be charged separately, and its battery life cannot be guaranteed to be consistent with that of a digital torque wrench, which also causes inconvenience to the operation
