Abstract
The utility model discloses a tool for moment measurement application, and aims to provide a digital torque wrench, which is mainly applied to detecting torque and screwing fasteners in the engineering field of steel pipe scaffolds. The wrench comprises an opening portion and a handle, a user can hold the handle to exert force, and a torque display device is arranged on the handle. The digital torque wrench utilizes a digital readout form, can greatly increase using efficiency, is convenient in operation, and provides more accurate reading for users.
Description
Technical field
The utility model relates to the instrument that a kind of torgue measurement is used, and specifically, is a kind of digital torque spanner, and the torsion detection and the fastener that are mainly used in fastener in the steel pipe scaffold engineering field are tightened.
Background technology
In architectural engineering, the use of steel pipe scaffold is very general, and according to code requirement, and setting up fastener nut in the process at steel pipe scaffold, to require torque value be 40～60Nm, the excessive or too small potential safety hazard that all causes easily.The main tool that detects torsion at present is a kind of scale formula torque spanner, mainly determines the torsion of fastener in testing process by pointer indication numeral on the dial, and therefore in use efficient is not high, and reading is made mistakes easily.If what adopt is the torque spanner of digital display mode, then can improve the efficient that fastener torsion is checked greatly, and the accuracy of fastener torsion enforcement.
The utility model content
The purpose of this utility model is to overcome the weak point of existing torque spanner, and it is low promptly to change the existing general service efficiency of torque spanner, and the phenomenon that the rate that misreads is higher provides a kind of digital torque spanner that can be more easy to use.
To achieve these goals, the utility model is realized by the following method:
A kind of digital torque spanner comprises the opening of spanner and the handle that can supply to hold the application of force, and described handle is provided with a torsion display unit.
As a kind of improvement of the present utility model, described torsion display unit is a LCDs.
As a kind of improvement of the present utility model, described LCDs is depressed in the body surface of described handle, does not in use subject to damage with the protection LCDs.
As a kind of improvement of the present utility model, at the opening of described spanner, promptly torque spanner and the contacted position of fastener nut are provided with the moment inductor.
As a kind of improvement of the present utility model, described moment inductor always has 3, and be located at respectively with the fastener nut is contacted and upper and lowerly pull a mouthful position, and the pulling on mouthful tooth position of the transition that mediates.
As a kind of improvement of the present utility model, described moment inductor is by being in the data wire in the spanner, and in succession mutually successively analog-digital converter and central processing unit link to each other with described LCDs again; The moment inductor is delivered to the pressurized signal of collecting on the analog-digital converter, by analog-digital converter again with digital signal transfers in central processing unit, the data signal that central processing unit was handled is presented at the display screen that is arranged on the handle with the form of numeral again.
As a kind of improvement of the present utility model, described digital torque spanner is a monkey wrench, can arbitrarily change wrench opening end size, to adapt to the fastener nut of various different sizes.
Compare existing scale formula torque spanner, the utility model adopts the digital display mode, can improve the service efficiency of spanner greatly, and is easy to operate, for the user provides more accurate reading.
Description of drawings
Fig. 1 is a schematic appearance of the present utility model;
Fig. 2 is a cut-away view of the present utility model;
Among the figure: 1 spanner, 2 moment inductors, 3 data wires, 4 analog-digital converters, 5 central processing units, 6 LCDs.
The specific embodiment
Below in conjunction with the drawings and specific embodiments the utility model is described in further detail:
As depicted in figs. 1 and 2, digital torque spanner of the present utility model is fixed solid wrench, and the size of its opening matches with the size that is used for the fastener nut on the steel pipe scaffold, and easily the workman uses; At handle part the LCDs 6 that a width is slightly less than the handle width is installed, this LCDs 6 is depressed in the body surface of handle, in case scratch damages screen surface; Opening at spanner, promptly on torque spanner and the contacted position of fastener nut, also be provided with moment inductor 2, this moment inductor 2 is being provided with 3 altogether, and promptly be located at respectively with the fastener nut is contacted and upper and lowerly pull a mouthful position, and the pulling on mouthful tooth position of the transition that mediates; These moment inductors 2 are by being in the data wire 3 in the spanner, and in succession mutually successively analog-digital converter 4 and central processing unit 5 link to each other with LCDs 6 again; When spanner 1 begins to tighten the fastener nut, the moment inductor 2 that is provided with on nut and wrench opening contact site is delivered to analog-digital converter 4 with the pressure signal of collecting by data wire 3, digital signal transfers with analog-digital converter 4 arrives central processing unit 5 again, and treated data signal is presented on the LCDs 6 with digital form, reads easily.
At last, it is also noted that what more than enumerate only is a specific embodiment of the present utility model.Obviously; the utility model can also have many distortion; such as: the form of wrench can be a monkey wrench; or box spanner or the like; all distortion that those of ordinary skill in the art can directly derive or associate from the disclosed content of the utility model all should be thought protection domain of the present utility model.
