Abstract
Description
Technical Field
[0001] The utility model relates to the technical field of luminance meter brackets, in particular to a positioning bracket for luminance meter measurement. Background Technique
[0002] A luminance meter mainly uses a pair of light holes at a certain distance to receive the luminous flux of a fixed solid angle and a fixed light projection area. This value does not change with the distance of the object as long as the surface area of the object is large enough. In order to aim at the object to be measured, an imaging system is often used. The measured light source forms an image on a perforated (front light hole) mirror after passing through the objective lens. A part of it passes through the mirror and the eyepiece and is received by the human eye to aim at and monitor that the clear imaging surface coincides with the perforated mirror;
[0003] During the use of the luminance meter, it is generally used in conjunction with a bracket. The traditional bracket only has a supporting function. When the bracket needs to be moved, the whole bracket needs to be picked up and moved, which is obviously more laborious. In addition, if the bracket is accidentally knocked down, it is easy for the luminance meter to directly hit the ground, resulting in damage. Content of the Utility Model
[0004] The purpose of the utility model is to solve the shortcomings existing in the prior art, and to propose a positioning bracket for luminance meter measurement. During the use of the positioning bracket, it is convenient to move it, and the stability during use is also relatively strong. Even if it is accidentally knocked down, it will not cause damage to the hardness meter due to hitting the ground.
[0005] In order to achieve the above purpose, the utility model adopts the following technical scheme:

Detailed implementation manner
[0023] Next, the technical solutions in the embodiments of the present invention will be clearly and completely described in conjunction with the accompanying drawings in the embodiments of the present invention. Obviously, the described embodiments are only a part of the embodiments of the present invention, rather than all the embodiments.
[0024] Refer to Figures 1-4 , a positioning bracket for a luminance meter measurement, including a bottom plate 1. A vertical rod 3 is fixedly connected to the upper end of the bottom plate 1. The upper end of the vertical rod 3 is fixedly connected to a mounting plate 4. A plurality of connection ports are opened on the mounting plate 4 for installing a luminance meter. Here, the luminance meter is a rotatable luminance meter. The rotatable luminance meter can adjust the angle of its measuring head or probe, so as to more accurately measure the luminance of light sources from different directions, and is suitable for a variety of measurement scenarios, including lighting engineering, light sources and light-emitting devices, film and television, traffic signals, architecture, atmospheric photometry and other fields;
[0025] Among them, a moving mechanism is further included. The moving mechanism includes a plurality of rollers 2 fixedly connected to the lower end of the bottom plate 1. All the plurality of rollers 2 are universal wheels, and the universal wheels can ensure multi-directional movement. A loop frame 7 is fixedly connected to the right side of the vertical rod 3. The loop frame 7 is equivalent to a handle;
[0026] Among them, a protection mechanism is further included. The protection mechanism is composed of three protection structures. The protection mechanism is used to protect the luminance meter. The protection structure includes a second U-shaped frame 17 fixedly connected to the side wall of the vertical rod 3. A rotating shaft 19 is rotatably connected between the two inner walls of the second U-shaped frame 17. A protective strip 8 is fixedly connected to the rotating shaft 19. First threaded holes are opened on both inner walls of the second U-shaped frame 17. A second threaded hole is penetrated through the protective strip 8. A limit screw 18 is commonly threadedly connected to the second threaded hole and the two first threaded holes;
[0027] Among them, an anti-slip mechanism is further included. The anti-slip mechanism is used to improve the stability of the bracket during use. The anti-slip mechanism includes a friction plate 12 arranged below the bottom plate 1. The upper end of the friction plate 12 is elastically connected to the lower end of the bottom plate 1 through a plurality of springs 13. The upper end of the friction plate 12 is fixedly connected with a plurality of first guide rods 11. The upper ends of the plurality of first guide rods 11 all penetrate through the bottom plate 1. The upper ends of the two first guide rods 11 located at the right end are jointly fixedly connected with a cross bar 10. Two second guide rods 14 are fixedly connected between the left and right inner walls of the loop frame 7. A slide bar 15 is arranged through the two second guide rods 14. A pull rope 9 is fixedly connected to the left side of the slide bar 15. The other end of the pull rope 9 is fixedly connected to the upper end of the cross bar 10. A first U-shaped frame 5 is fixedly connected to the right side of the vertical rod 3. A guide wheel 6 is rotatably connected between the front and rear inner walls of the first U-shaped frame 5. The pull rope 9 contacts the guide wheel 6. Two rectangular blocks 16 are fixedly connected to the left side of the slide bar 15.
[0028] In the present utility model, during practical use, the luminance meter is installed on the upper end of the mounting plate 4. Then, by holding the loop frame 7, the entire bracket is moved. When holding the loop frame 7, the index finger will pull the slide bar 15 to move rightward, thereby driving the pull rope 9 to drive the cross bar 10 to move upward. The upward movement of the cross bar 10 will drive the plurality of first guide rods 11 to move upward, thereby driving the friction plate 12 to move upward, so that the friction plate 12 does not contact the ground. At this time, the entire bracket can be moved. After moving to the appropriate position and in the appropriate direction, positioning is completed. Release the loop frame 7. Under the elastic action of the spring 11, the friction plate 12 contacts the ground, ensuring the stability during use. At this time, the positioning adjustment can be performed again through the rotation structure of the luminance meter body until the use requirements are met.
[0029] During the support process of the bracket, if it is accidentally knocked down, the plurality of protective strips 8 will first contact the ground, avoiding the situation that the luminance meter hits the ground, and playing a good protective effect. When the whole is not needed to be used, the plurality of limit screws 18 can be wedged. At this time, the plurality of protective strips 8 will automatically rotate to the vertical state, so that the whole right angle will not occupy a large horizontal space.
[0030] The above is only a preferred specific embodiment of the present utility model, but the protection scope of the present utility model is not limited thereto. Any person skilled in the art within the technical scope disclosed by the present utility model, according to the technical solution of the present utility model and its inventive concept, makes equivalent substitutions or changes, and should be covered within the protection scope of the present utility model.
