Description
Technical Field
The utility model belongs to the detection area, concretely relates to cement detection area relates to an adjustable light ring formula diameter measurement appearance.
Background
The fluidity of cement mortar is a measure of the fluidity of cement mortar, and at a certain water addition, the fluidity depends on the water demand of cement. Fluidity is expressed in terms of the mean diameter (MM) of the cement mortar spread on the flow table. When measuring cement mortar fluidity and measuring the diameter of a circle formed by the depth of a pavement structure by a manual sand paving method, a vernier caliper is generally used for measuring the diameter, so that the measurement accuracy is low, the method is very inconvenient, and cement is easy to stick to the vernier caliper or an operator.
SUMMERY OF THE UTILITY MODEL
In order to solve the problem, the utility model provides an adjustable aperture formula diameter measuring apparatu can realize the accurate measurement of cement mortar mobility diameter.
The specific implementation scheme is as follows:
the utility model provides an adjustable aperture formula diameter measurement appearance, its characterized in that includes iron stand platform, light source, the angle measuring apparatu of adjustable light source of aperture, light source and angle measuring apparatu of adjustable light source of aperture pass through the clip and are connected with the iron stand platform, the neutral line of angle measuring apparatu and the neutral line of light source is in same straight line with adjustable light aperture.
Further, the angle measuring instrument is arranged above the light source with the adjustable aperture, and a graduated scale is arranged on the vertical rod of the iron support.
Further, the aperture-adjustable light source comprises a power supply part, a light-emitting part, a zoom ring and an optical zoom lens, wherein the power supply part, the light-emitting part, the zoom ring and the optical zoom lens are sequentially arranged from top to bottom, and the aperture-adjustable light source is similar to an aperture-adjustable flashlight device.
Further, the angle measuring instrument is a digital display angle ruler, and an infrared laser pen is arranged at the front end of one of the digital display angle ruler and the digital display instrument.
Further, the light emitted by the aperture-adjustable light source is colored light, such as red, green, yellow, blue, and the like.
Has the advantages that: the utility model can accurately measure the fluidity diameter of the cement mortar; simple operation and good effect.

FIG. 1 is a schematic view of the present invention;
FIG. 2 is an enlarged view at A;
wherein, 1, an iron stand platform; 2 a power supply unit; 3 a light emitting section; 4, a zoom ring; 5 an optical zoom lens; 6, a digital display instrument; 7 infrared laser pen; 8 digital display angle ruler.
Detailed Description
The adjustable aperture type diameter measuring instrument shown in fig. 1 comprises an iron support 1, an aperture adjustable light source and an angle measuring instrument, wherein the aperture adjustable light source and the angle measuring instrument are connected with the iron support through clamps, and a neutral line of the angle measuring instrument and a neutral line of the aperture adjustable light source are on the same straight line.
Further, the angle measuring instrument is arranged above the light source with the adjustable aperture, and a graduated scale is arranged on the vertical rod of the iron support 1.
Further, the aperture-adjustable light source comprises a power supply part 2, a light emitting part 3, a zoom ring 4 and an optical zoom lens 5, wherein the power supply part 2, the light emitting part 3, the zoom ring 4 and the optical zoom lens 5 are sequentially arranged from top to bottom.
Further, the angle measuring instrument is a digital display angle ruler 8, and an infrared laser pen 7 is arranged at the front end of the digital display angle ruler 8, which is provided with the digital display instrument 6.
The utility model discloses an operating principle:
taking an aperture-adjustable light source composed of the power supply part 2, the light emitting part 3, the zoom ring 4 and the optical zoom lens as an example, the digital display angle ruler 8 is used as an angle measuring instrument, and an infrared laser pen 7 is arranged at the front end of the digital display angle ruler 8, which is provided with the digital display instrument 6.
The aperture-adjustable light source and the angle measuring instrument are arranged on the iron clamp table 1 through the clamp, so that the neutral line of the angle measuring instrument and the neutral line of the aperture-adjustable light source are on the same vertical straight line.
Adjust the facula of light source with adjustable light ring through ring 4 and to the minimum, place cement mortar in the center department of facula, make cement mortar to scatter all around, the size of 4 adjustment facula through the focus ring, it is close to make facula and cement mortar form the approximate circle size of figure profile (can suitably remove the iron stand platform, make the center of light source with adjustable light ring and cement mortar form the approximate circle center of figure profile and coincide), 8 front ends of adjustment digital display bevel protractor set up infrared laser pen 7 and the coincidence of facula border, measure the angle, through the height h who measures 8 tops of digital display bevel protractor and platform, just can calculate out the radius r that the cement mortar formed the approximate circle of figure profile in combination with triangle-shaped relevant knowledge. The digital display angle ruler 8 (the light source with the adjustable aperture and the angle measuring instrument are connected with the clamp of the iron support through the bearing) can be used for measuring for multiple times, and the average value is obtained, so that the result is more accurate. The light emitted by the aperture-adjustable light source is colored light, such as red, green, yellow, blue and other colored light sources, so that the measurement can be conveniently carried out in the daytime (under the condition of natural light), and the interference of the natural light is avoided.
