Description

Torsion structure

The present invention is related to a torsion structure, in particular, a torsion structure in which a first groove contains a first strain gauge and a second strain gauge, the first strain gauge detects the bending displacement, the second strain gauge detects the torsion deformation, and the first strain gauge and the second strain gauge increase the functionality of the torsion structure.

As we know, in the commonly used torque wrench structure, such as US Patent No. US10625405B2, Taiwan Patent Case No.: 106213628, Patent Name: Electric Ratchet Torque Wrench, the patent case structure is: an electric tool, including: a motor 18 having a motor drive shaft 20; a drive assembly 22 coupled to the motor drive shaft 20 and driven by the motor 18; an output assembly 24 is coupled to the drive assembly 22 and has an output member 102 that receives torque from the drive assembly 22, so that the output member 105 can rotate around an axis A; and a conversion assembly 118 is arranged between the motor 18 and the output assembly 24, which can measure the torque applied by the output member 102 in response to the power tool being rotated around the axis A by human power when the motor 18 is not actuated.

However, the shortcomings of this conventional electric ratchet torque wrench are:

1. The conventional electric ratchet torque wrench measures the torque force applied by turning the main body 13. The structure only measures the torque force during turning, that is, it only measures a single functionality, which is slightly insufficient.

2. The output assembly 24 is assembled with the conversion assembly 118, the conversion assembly 118 is assembled with the gear housing 36 of the drive assembly 22, and the gear housing 36 is fixed to the main housing 12, that is, there are four assemblies assembled in sequence, and the assembly structure is a sequential structure and is relatively poor.

In view of the above shortcomings of the conventional structure, the inventor, with many years of experience in manufacturing, production and design in related industries, finally came up with a torsion structure product that can solve the conventional shortcomings.

The conventional electric ratchet torque wrench measures the torque applied by turning the main body. The structure only measures the torque during turning, that is, only measures a single functionality, which is slightly insufficient. In the torque structure of the present invention, the first slot contains the first strain gauge and the second strain gauge. The first strain gauge detects the bending turning amount, and the second strain gauge detects the torsional deformation amount. The first strain gauge and the second strain gauge increase the functionality of the torque structure.

A torque structure includes: a first body having a first receiving groove, a first sleeve portion and a first axis; a first strain gauge for detecting the bending displacement of the first body when the first body is pulled; a second strain gauge for detecting the torsional deformation of the first body; a second body assembly having a second body, a display, a shell and a power supply element; the second body having a second receiving groove, a first opening, a second opening and a through groove; the display is assembled at the through groove, and the display has a switch, a first button and a second button; the first strain gauge is electrically connected to the display; the second strain gauge is electrically connected to the display; the shell and the power supply element are accommodated in the second receiving groove.

The first receiving groove accommodates the first strain gauge and the second strain gauge. The first strain gauge can detect the bending displacement, and the second strain gauge can detect the torsional deformation. The two first strain gauges and the second strain gauges with different detection functions increase the functionality of the torque structure. If the first sleeve portion is assembled with the driving part having the rotatable driving part, when the driving part rotates to two directions, the torque structure can measure the torque value, that is, there is no need to purchase two different torque wrench structures and torque screwdriver structures for measuring the torque value. The torque structure has a dual function when measuring the torque value. The first sleeve portion can be sleeved with the driving parts of two different structures. The second axis is perpendicular to or coincides with the first axis, and the torque value can be measured.

In order to enable the members of the Jun Bureau and those familiar with this technology to fully understand the effects of the present invention, the structure and composition of the present invention are explained below with diagrams and figure numbers. However, the following is only used to explain the implementation examples of the present invention and is not intended to limit the present invention in any form.
