Description

Technical Field

[0001] The utility model relates to the field of outdoor field archaeology, in particular to a retractable portable reflective cloth for outdoor use. Background Art

[0002] Field archaeology is the foundation of archaeology. It is an archaeological survey, exploration and excavation work conducted in the wild. It uses scientific methods and techniques to systematically discover, record and study the relics and artifacts left by ancient humans. In the process of field archaeology, in order to have good lighting conditions to help accurately record the characteristics of the relics and cultural relics when they were unearthed, including shape, texture, color and various traces on them, reflective cloth is needed. Reflective cloth is a lighting auxiliary tool used in photography. It is usually made of materials such as tinfoil, white cloth, and rice pineapple. Reflective cloth plays an auxiliary lighting role outside the scene. The function of reflective cloth is to fill in the dark part of the subject by reflecting light to obtain a good image effect. According to the material, it can be generally divided into hard reflective cloth or soft reflective cloth. According to the color, it can be generally divided into white, silver, gold, black, etc. The common movable outdoor reflective cloth on the market is usually a circular reflective cloth with a maximum diameter of 1.1 meters or an elliptical reflective cloth with a long diameter of up to 2 meters. This type of reflective cloth is small in area and not portable, and is not suitable for the photography of relics in field archaeology.

[0003] The existing technology has the following two defects: First, the cost of revealing the relics is high and the photography effect is poor. In field archaeological surveys or excavations, the exposure of the relic units requires a lot of manpower and material resources, and the revealed relic units are very susceptible to damage due to changes in natural conditions, such as sun exposure and rain, so they need to be photographed and recorded in time, but the photography of relic units is often restricted by changes in the weather in the field; in the process of field archaeological practice, in order to timely photograph and record the relic phenomena, usually regardless of whether it is sunny or cloudy, the relics are immediately photographed when they are exposed. When there is no suitable shelter on the construction site, they can only passively wait for the light conditions to change before taking pictures, resulting in poor photography effects, the relic phenomena are not clear enough, the dark parts are not well lit, and the bright parts are overexposed. In the dark light, due to the lack of suitable reflective equipment, there is basically no fill light measure. The photos of large relic units are usually overexposed in part and shadowed in part, which is not convenient for later archaeological experts to study and analyze the relic phenomena.

[0004] Second, the existing general-purpose photographic reflective cloth is not suitable for field archaeology. The general-purpose reflective cloth currently available on the market is mostly used indoors, has a small area, and is mostly hard cloth, which is not easy to move and is not suitable for outdoor work. During field archaeological work, the exposed positions of relics are uncertain and of different sizes. This requires that photographic equipment such as reflective cloth needs to be movable at any time and easy to adjust in size. There is currently no reflective cloth suitable for outdoor relic photography on the market. Therefore, in the current practice of field archaeological photography work, when there is strong light, it is usually necessary to spend a lot of manpower to pull colored strips of cloth or use parasols for temporary light shielding for shooting, which requires several workers to stop their work and pull the sunshade. To this end, a retractable and portable reflective cloth for outdoor use is proposed to solve the above problem. Utility Model Content

[0031] Reference Figure 1-Figure 3 The utility model provides an embodiment: a retractable portable reflective cloth for outdoor use, including a connecting tube 1, the inner wall of the connecting tube 1 is movably connected to a movable tube 2, the movable tube 2 can move vertically and rotate along the inner wall of the connecting tube 1 with a fixed block 3, the movable tube 2 is provided with multiple groups, the outer walls of the multiple groups of movable tubes 2 are fixedly connected with a fixed block 3, the connecting tube 1 and the movable tube 2 are made of aluminum alloy, and the material is cheap, light and has high hardness, which is convenient for outdoor archaeological carrying, the outer wall of the fixed block 3 is connected with a card slot 4, and the card slot 4 is vertically and horizontally opened, such as Figure 3 and Figure 4 As shown, when the fixed block 3 and the vertical opening coincide with each other, the movable tube 2 can be moved vertically on the inner wall of the connecting tube 1. When the fixed block 3 and the horizontal opening coincide with each other, the movable tube 2 cannot be moved vertically on the inner wall of the connecting tube 1. The inner wall of the slot 4 is provided with a friction pad 9, which allows the upper and lower ends of the fixed block 3 to contact the friction pad 9. In order to increase its friction, it is necessary to manually apply a certain force to allow the fixed block 3 to rotate in the slot 4. The outer wall of the connecting tube 1 is provided with an anti-slip sleeve 5. The surface of the anti-slip sleeve 5 is provided with multiple rubber blocks, which can increase the friction during the hand holding process of the staff. The outer wall of the connecting tube 1 is fixedly connected to a fixing ring 6. The middle part of the fixing ring 6 is penetrated by a reflective cloth 8 through a clamping rope 7. The reflective cloth 8 is provided with two sides, one side of the reflective cloth 8 is reflective white, and the other side is light-absorbing black. The light-absorbing black is composed of existing paint.

[0032] Reference Figure 2-Figure 4 , multiple groups of movable tubes 2 are movably connected, such as Figure 1 As shown, there is a card slot 4 corresponding to the connecting tube 1 in the movable tube 2, and there is a fixed block 3 on the movable tube 2, so that the movable tubes 2 can also be stretched and retracted. The outer walls of the multiple groups of movable tubes 2 are fixedly connected with a fixing ring 6. The number of fixing rings 6 is relative to the number of clips 7. The fixing rings 6 can be connected to the clips 7 to connect and support the reflective cloth 8. The inner walls of the multiple groups of movable tubes 2 are provided with a card slot 4. The middle part of the fixing ring 6 passes through one end of the clip 7, and the other end of the clip 7 passes through the inner wall of the reflective cloth 8. The clip 7 consists of a snap and a rope cloth. The snap is a prior art and can quickly disassemble and assemble the reflective cloth 8. The outer wall of the fixing block 3 is in contact with the outer wall of the friction pad 9. The card slot 4 is provided on the inner wall of the connecting tube 1, and multiple groups of clips 7 are provided on both sides of the reflective cloth 8.

[0033] Working principle: First, you need to extend the movable tube 2 on the connecting tube 1 for use, such as Figure 4 As shown, the fixed block 3 is located at the vertical opening of the slot 4, and the movable tube 2 can be moved vertically along the inner wall of the connecting tube 1 with the fixed block 3 to adjust its telescopic length. When the movable tube 2 is telescoped to the specified length, it is only necessary to rotate the movable tube 2 counterclockwise with the fixed block 3 into the horizontal opening of the slot 4, so that the slot 4 contacts the friction pad 9 to ensure the stability of the rotation connection. Multiple groups of movable tubes 2 can be adjusted individually according to the actual telescopic situation, such as Figure 1 As shown, the connecting tube 1 and the movable tube 2 are displayed after adjustment. If the connecting tube 1 and multiple sets of movable tubes 2 need to be stored, just turn the movable tube 2 clockwise with the fixed block 3 to move it, so that the fixed block 3 enters the vertical opening of the slot 4 from the horizontal opening of the slot 4. At this time, according to the storage situation, move the movable tube 2 with the fixed block 3 along the vertical opening of the slot 4, so that the movable tube 2 is completely stored in the interior of the connecting tube 1. Multiple sets of movable tubes 2 can also be operated according to the above steps.

[0034] according to Figure 1 As shown in the device, the front side of the reflective cloth 8 is white reflective material, which can fill in the shadow area of ​​the archaeological relic unit, making the details of the photographed relic clear and without dark areas. The back side of the reflective cloth 8 is black light-absorbing material, which can be used to absorb excess light, reduce the reflection and scattering of the surrounding ambient light, and create a relatively dark background, so that the details of the cultural relics can be more clearly displayed.

[0035] Finally, it should be noted that the above is only a preferred embodiment of the present invention and is not intended to limit the present invention. Although the present invention has been described in detail with reference to the aforementioned embodiments, those skilled in the art can still modify the technical solutions described in the aforementioned embodiments or make equivalent replacements for some of the technical features therein.
