Description

Technical Field

[0001] The invention relates to the field of advertisement design, in particular to a measuring device for advertisement design. Background Art

[0002] Advertising design is a combination of five elements: theme, creativity, language, image, and background. The ultimate goal of advertising design is to attract attention through advertising. When designing a billboard, the exact size of the billboard is measured so that the proportion of the designed advertisement can be better displayed.

[0003] The existing patent (Announcement No.: CN222165913U) discloses a measuring device for advertising design, including: a U-shaped frame and a square frame, the square frame is arranged below the U-shaped frame, and also includes: a rotating rod 2, which is movably embedded in the center of the bottom of the square frame, a knob is fixedly installed on one end of the rotating rod 2, and a fixed ring is fixedly sleeved on the outer surface of the rotating rod 2 near the center. The utility model manually presses the ruler downward, so that the sleeve rod drives the movable ring to slide downward along the outer surface of the rotating rod 2, and the spring 2 is stretched synchronously, so that the ruler can be attached to the advertising design paper below, and the measurement and marking operation can be carried out at this time. When the measurement is completed, the ruler can be loosened, so that the ruler can move upward under the reset force of the spring 2, so that the advertising design paper can be prevented from being damaged due to the misoperation of the measuring personnel, thereby ensuring the efficiency of advertising design marking. In the process of realizing the present invention, the inventors found that there are at least the following problems in the prior art that have not been solved: 1. When measuring billboards of different sizes, the equipment needs to be adjusted in sequence, and the length-to-width ratio needs to be measured and marked separately, which affects the measurement efficiency and speed of the advertising design; 2. When measuring billboards, it is necessary to manually press the equipment for measurement, and the data needs to be viewed by a Panasonic device during measurement, so the marked size will produce slight errors, affecting the accuracy of the data.

[0025] The use method and advantages of the present invention: The use method of the measuring device for advertising design, the working process is as follows: like Figure 1 , Figure 2 , Figure 3 , Figure 4 , Figure 5 , Figure 6 , Figure 7 , Figure 8 , Fig.10 and Fig.11 As shown: when the measuring device is placed on a square billboard, the driving motor 2 drives the driving column 3 and the engaging cylinder 151 to rotate, and at the same time drives the cylinder 4 sleeved by the engaging cylinder 151 to rotate, so that when the first gear 5 and the second gear 16 rotate, the first tooth plate 61 and the second tooth plate 17 are respectively moved toward each other for adjustment, so that the first measuring plate 23 and the second measuring plate 24 connected below stop, and the adjusted advertisement size is marked, and then the driving motor 2 is reversed to reset the first measuring plate 23 and the second measuring plate 24; When measuring the size of the rectangular plate, the first tooth plate 61 and the first measuring plate 23 at the bottom will first contact the billboard through the rotation drive of the driving motor 2. After encountering resistance, the first gear 5 stops rotating, so that the internal connecting torsion spring 13 and the built-in column 14 continue to rotate. At the same time, the second triangular block 157 on the outer wall of the engaging cylinder 151 will contact the stopped first triangular block 7 during the rotation process, so that the engaging cylinder 151 is lifted up and separated from the sleeved cylinder 4. During the separation, the spring inside the spring telescopic rod 153 on the outer wall of the engaging cylinder 151 is compressed. After the engaging cylinder 151 is moved up, the spring pressure inside the spring telescopic rod 153 is released, and the engaging cylinder 151 is supported and fixed. At the same time, during the lifting process of the engaging cylinder 151, the lifting ring 156 on the outer wall will contact the adjusting card plate 122, so that the adjusting card plate 122 deflects with the penetrating column 121 as the deflection axis, driving the positioning block 125 at the bottom to engage in the outer wall tooth groove of the first gear 5, and the first gear 5 is engaged and fixed. At this time, the engaging cylinder 151 and the second gear 16 separated from the cylinder 4 continue to rotate, and the size of the second tooth plate 17 and the second measuring plate 24 are adjusted. After reaching the position, the device driving is stopped, and the spring button 21 is pressed to make the internal spring buckle push the engaging tooth plate 22, so that the engaging tooth plate 22 engages and fixes the second gear 16, and then the size is marked; After the marking is completed, the spring button 21 is pressed again to make the spring buckle pop out the latch plate 22, so that the latch plate 22 is separated from the second gear 16, and then the driving motor 2 is reversed to make the second gear 16 drive the second gear plate 17 to reset, so that the square column 181 and the extension plate 182 at the bottom contact the outer wall of the upper corner of the adjustment card plate 122, so that the upper ends of the adjustment card plates 122 on both sides are pushed toward the middle, so that the bottom positioning block 125 is separated from the first gear 5, so that the internal connecting torsion spring 13 and the built-in column 14 are rotated and reset, and at the same time, the Under the action of the compression force of the long spring 62, the first tooth plate 61 is reset. After the second tooth plate 17 continues to reset, the connected side plate 183 and the lower pressure plate 184 will contact the top of the lower plate 158 and push it downward, so that when the locking cylinder 151 moves downward, the spring of the outer wall spring telescopic rod 153 is compressed again. After the downward movement is completed, the spring of the spring telescopic rod 153 is released to support and fix the locking cylinder 151, so that the locking cylinder 151 is again limited and slidably sleeved on the limiting groove at the upper end of the cylinder 4, and the operation can be completed.
