The technical solution of the utility model solution technical problem are as follows:
A kind of Stiffness tester, including the first shell, single pendulum, camera, signal processing circuit board, the single pendulum include cord
With the pendulum for lying in cord one end, the other end of the cord is fixedly installed on the inside of the first sheath top plate, the camera shooting
Head is set to the underface of pendulum, and the plumb line of its capture central axes and pendulum is point-blank, the camera with
Signal processing circuit board electrical connection, further includes second housing, first shell is fixedly installed on inside second housing, described
Signal processing circuit board is installed on the outer wall of the first shell or on the inner wall of second housing.
Further, the signal processing circuit board is connected with data line, and the other end of the data line is pierced by second
It is connect after shell with signal receiving end.
Further, the second housing is cylinder, and its side is equipped with outwardly projecting corner angle.
The effect provided in utility model content is only the effect of embodiment, rather than whole effects that utility model is all
Fruit, a technical solution in above-mentioned technical proposal have the following advantages that or the utility model has the advantages that
1, the first shell is fixedly installed on inside second housing by the utility model by setting second housing, by the
Other all parts including signal processing circuit board are sealed in second housing by two shells, are avoided including signal
Other all parts including processing circuit plate improve Stiffness tester because damaging caused by the airtightness such as humidity, dust deficiency
Service life play the protection to other all parts including signal processing circuit board on the other hand by second housing
Effect.
2, the utility model passes through corner angle and installation position by being equipped with outwardly projecting corner angle on the side of second housing
The recess set is cooperated, convenient for being positioned to Stiffness tester, measurement data deviation caused by avoiding it from rotating.
Detailed description of the invention
Fig. 1 is the slope structure schematic diagram of the utility model；
Fig. 2 is the top view of the utility model；
In figure, the first shell 1, single pendulum 2, cord 21, pendulum 22, camera 3, signal processing circuit board 4, data line 41,
Second housing 5, corner angle 51.
Specific embodiment
In order to clearly illustrate the technical characterstic of this programme, below by specific embodiment, and its attached drawing is combined, to this
Utility model is described in detail.Following disclosure provides many different embodiments or example is used to realize the utility model
Different structure.In order to simplify the disclosure of the utility model, hereinafter the component of specific examples and setting are described.This
Outside, the utility model can in different examples repeat reference numerals and/or letter.This repetition is in order to simplified and clear
Purpose itself does not indicate the relationship between discussed various embodiments and/or setting.It should be noted that illustrated in the accompanying drawings
Component be not drawn necessarily to scale.The utility model be omitted the description to known assemblies and treatment technology and process to avoid
It is unnecessarily limiting the utility model.
A kind of Stiffness tester, including the first shell 1, single pendulum 2, camera 3, signal processing circuit board 4, the single pendulum 2 wrap
It includes cord 21 and lies in the pendulum 22 of cord one end, pendulum cord 21 freely sagging, described under the suspension of cord
The other end be fixedly installed on the inside of 1 top plate of the first shell, the camera 3 is set to the underface of pendulum 22, described
Camera is installed on the bottom plate of the first shell 1, the camera be night-viewable camera or the camera with lamp source, and
Point-blank, the camera 3 is electrically connected the plumb line of its capture central axes and pendulum with signal processing circuit board 4,
The gradient of Stiffness tester can be calculated by collecting the angle between pendulum plumb line and camera capture central axes by camera,
It further include second housing 5, the second housing is the closure of metal production, and first shell 1 is fixedly installed on the
