Abstract
The utility model discloses an instrument installation rod comprising a first straight rod, and a first pedestal and a second pedestal both installed along the axial direction of the straight rod. The straight rod is fixed onto the surface of a to-be-measured member by the first pedestal; the second pedestal is detachably connected with the straight rod; a measurement meter is fixed onto the surface of the to-be-measured member by the second pedestal at a measuring state and the measurement head of the measurement meter is located in the extending line of the axis of the straight rod; the end of the measurement head is pressed against the end of the straight rod; and the meter measurement head, when the to-be-measured member deforms along the axial direction of the straight rod, telescopes and deforms so as to cause meter reading changes. The provided instrument installation rod cooperates with the measurement meter so that the measurement is direct and simple, the data is reliable, and the cost is relatively low.
Description
Technical field
The utility model relates to the device that a kind of instrument is installed, and is fit to measure the changing value of leverage member length under force-bearing situation.
Background technology
At present, the instrument that detects the length variations value mainly contains foil gauge, strainometer etc., and the advantage of this quasi-instrument is: simple and clear, directly obtain strain data, shortcoming is directly to obtain the length variations value, and can not reflect intuitively the variable quantity of leverage member length under force-bearing situation.
The utility model content
In order to obtain intuitively the changing value of unit length, the utility model provides a kind of instrument install device, and dial gauge or clock gauge can conveniently be installed, and is used for obtaining the changing value of unit length.
to achieve these goals, the utility model has adopted following technical scheme: a kind of instrument mounting rod, it is characterized in that: comprise a straight-bar, the first base and the second base along described straight-bar axis direction installation, the first base is fixed in component surface to be measured with described straight-bar, the second base removably is connected with described straight-bar, the second base is fixed in component surface to be measured with measuring instrument when measuring state, and the measuring head of measuring instrument is on the extended line of described straight-bar axis, the measuring head end presses on the end of described straight-bar, when member to be measured during along straight-bar axis direction generation deformation, thereby described instrument measurement head produces the variation that dilatation causes meter reading.
Described straight-bar has a body of rod that is made of hollow tubular, at least one end of described hollow tubular is provided with internal thread, described straight-bar also comprises at least one screw-like termination, described screw-like termination is provided with the external thread that the internal thread with described hollow tubular is spirally connected, and described screw-like termination removably is spirally connected fixing with the described body of rod.
but a kind of measurement mechanism of Quick Measurement leverage member length variations value, it comprises: a measuring instrument reaches just like upper arbitrary described instrument mounting rod, first base of described measuring instrument mounting rod by the instrument mounting rod is fixed on member to be measured and straight-bar is parallel with the outside surface of member to be measured, measuring head and described straight-bar that second base of described measuring instrument by the instrument mounting rod is fixed in member to be measured and measuring instrument are positioned on same axis, the measuring head end presses on the end of described straight-bar, when member to be measured during along straight-bar axis direction generation deformation, thereby described instrument measurement head produces the variation that dilatation causes meter reading.
Instrument mounting rod of the present utility model, its base with straight-bar for removably being connected, base is fixed in straight-bar and measuring instrument the outside surface of member to be measured, and make straight-bar and measuring instrument coaxial, when member generation deformation to be measured, measuring instrument namely can produce reading, thereby obtain the deformation data of member to be measured, detection is got up very directly perceived, easy, and data are reliable, and expense is lower.
Description of drawings
Below in conjunction with drawings and Examples, the utility model is further illustrated.
Fig. 1 is the structural representation of instrument mounting rod.
Fig. 2 is the STRUCTURE DECOMPOSITION schematic diagram of straight-bar.
Fig. 3 is the structural representation after the installation instrument.
1-termination, 1.1-cylinder, 1.2-cap body, 2-screw, 3-straight-bar, 3.1-hollow tubular, 4.1-the first base, 4.2-the second base, 5-member to be measured, 6-measuring instrument.
Embodiment
Be illustrated in figure 1 as the instrument mounting rod of not installation and measuring instrument, the first base 4.1 and the second base 4.2 that it comprises straight-bar 3, installs along described straight-bar 3 axis directions.
Straight-bar 3 by cylinder type hollow pipe 3.1 and be positioned at the pipe two ends termination 1 consist of.At least one termination is obtained with hollow tubular 3.1 by dismountable mode and is connected.In this example, the termination 1 of an end of close the second base 4.2 is connected by dismountable mode with hollow tubular 3.1.But as a kind of implementation wherein, the nose end of hollow tubular 3.1 is provided with internal thread.Termination 1 is screw-like, has with externally threaded cylinder 1.1 and the external diameter cap body 1.2 greater than hollow tubular 3.1 external diameters, and by being spirally connected of cylinder 1.1 and hollow tubular 3.1, described termination 1 removably is spirally connected fixing with described hollow tubular.Certainly, the termination that straight-bar 3 can be set to its two ends all can removably be connected with hollow tubular 3.1, and connected mode also is not limited to be spirally connected, and can select other existing mechanical connection manner.At non-measuring state, the first base 4.1 and the second base 4.2 are installed on respectively straight-bar 3 near the position of two ends.
Be illustrated in figure 3 as a whole set of measurement mechanism, it comprises measuring instrument 6 and instrument mounting rod.When mounted, at first the termination 1 near the second base 4.2 1 ends is turned on, the slip straight-bar breaks away from straight-bar 3 and the second base 4.2.The first base 4.1 and the second base 4.2 are individually fixed in member to be measured 5 surfaces, and two bases are in same axis and keep a determining deviation, for example 40cm.Tighten the screw 2 of the first base top, straight-bar 3.1 is fixing, make it parallel with the outside surface of member 5 to be measured.Measuring instrument 6 is fixed in member to be measured 5 surfaces by the second base, and the measuring head 6.1 of measuring instrument is on the extended line of described straight-bar 3 axis, and measuring head 6.1 ends press on termination 1.Because measuring head 6.1 is made of telescopic loop bar, when member to be measured during along straight-bar axis direction generation deformation, thereby described instrument measurement head produces the variation that dilatation causes meter reading.Reading instrument numerical value; Determine the changing value of leverage member length by the change amount of instrument numerical value.
Instrument use dial gauge to be measured or clock gauge.
