[0025] In order to make the technical means, creative features, objectives and effects achieved by the present invention easier to understand, the present invention is further described below in conjunction with specific implementation methods.

[0026] like Figure 1As shown, an automatically illuminated level scale and indicating device includes a level scale assembly 1, wherein the outer surface of each section of the level scale assembly 1 is slidably connected to a moving assembly 2, the front side of the moving assembly 2 is fixedly connected to a lighting assembly 3, the lower front part of the moving assembly 2 is fixedly connected to a cleaning assembly 4, and the upper rear part of the moving assembly 2 is fixedly connected to a battery compartment 5.

[0027] like Figure 2 As shown, the level gauge scale assembly 1 includes a scale 11 , a slot 12 is provided on the left and right sides of the scale 11 , and a rotating shaft 13 is fixedly connected to the middle of the left side and the middle of the right side of the scale 11 .

[0028] like Figure 3 As shown, the moving assembly 2 includes two connecting plates 21 slidably connected to the left and right sides of the scale 11, and a semicircular groove 22 is provided in the middle of the ends of the two connecting plates 21 close to each other. The rear sides of the ends of the two connecting plates 21 close to each other are fixedly connected to friction plates 23, and the rear sides of the two connecting plates 21 are connected to an adjusting part 25 that rotates together, and the rear side of the adjusting part 25 is fixedly connected to a supporting plate 24.

[0029] like Figure 4 As shown, the adjusting portion 25 includes two push plates 251, which are rotatably connected to the connecting plate 21 on the same side. The two push plates 251 are horizontally symmetrically arranged, and a fixed box 253 is provided between the two push plates 251. The middle part of the inner cavity of the fixed box 253 is fixedly connected to a plate body 255. The ends of the two push plates 251 that are close to each other pass through the fixed box 253 and the plate body 255. The ends of the two push plates 251 that are close to each other are fixedly connected to a handle 252. The outer surfaces of the two push plates 251 are both sleeved with springs 254, and the two springs 254 are both arranged between the inner wall of the fixed box 253 and the plate body 255.

[0030] like Figure 3 As shown, the lighting assembly 3 includes a lighting lamp 31 and a reflector 32 respectively fixedly connected to the front sides of the ends of the two connecting plates 21 close to each other;

[0031] During actual use of the device, when it is necessary to adjust the lighting position of the level gauge scale, the operator holds the two handles 252 with his hands and moves the two handles 252 toward the plate body 255, and then the push plate 251 drives the connecting plate 21 to rotate. Since the corners on the rear side of the scale 11 are rounded, they can rotate on the friction plate 23, and the angle between the connecting plate 21 and the push plate 251 changes from a right angle to an obtuse angle. The moving assembly 2 and the scale 11 are no longer tightly fitted. Then the operator continues to hold the handles 252 and presses the supporting plate 24 with his hands to drive the moving assembly 2 to move in the vertical direction under the guidance of the rotating shaft 13. At this time, the illuminating lamp 31 fixed on the front side of the connecting plate 21 is also moving to illuminate the scale 11, and the reflector 32 can reflect the light emitted by the illuminating lamp 31.

[0032] The battery compartment 5 is fixedly connected to the upper end of the fixing box 253. The battery compartment 5 contains batteries. The battery compartment 5 is electrically connected to the lighting lamp 31 through a wire.

[0033] The lighting lamp 31 is a prior art, specifically an LED lamp, which is powered by a battery installed in the battery compartment 5; the reflector 32 is a lighting auxiliary tool, which can reflect the light emitted by the lighting lamp 31 and guide the light to the dark part or shadow area of ​​the level scale, thereby enhancing the overall lighting effect of the level scale. The appropriate installation position and angle of the reflector 32 can also reduce the possibility of the lighting lamp 31 directly shining into the operator's eyes, avoid glare, and enable the operator to perform measurement work more comfortably.

[0034] like Figure 5 As shown, the cleaning assembly 4 includes two connecting columns 41 fixedly connected to the front sides of the lower ends of the two connecting plates 21, and the lower ends of the two connecting columns 41 are fixedly connected to sliding plates 42, and the ends of the two sliding plates 42 close to each other are each provided with a second notch 43, and the middle parts of the ends of the two sliding plates 42 close to each other are each provided with a square hole 44, and the two second notches 43 are each slidably connected to a fixing plate 45, and the middle part of the front end of the fixing plate 45 is fixedly connected to a slide rail 46, and the outer surface of the slide rail 46 is slidably connected to two symmetrically arranged fixing blocks 47, and the protrusions of the two fixing blocks 47 are adapted to the shape of the square holes 44, and the rear end of the fixing plate 45 is fixedly connected with a Velcro;

[0035] In actual use of the device, when the moving assembly 2 is moving, the connecting plate 21 drives the sliding plate 42 and the fixed plate 45 to move through the connecting column 41. A wiping cloth is fixed to the rear end of the fixed plate 45 by Velcro. During the movement of the fixed plate 45, the wiping cloth cleans the surface of the level gauge scale.

[0036] When the wiping cloth needs to be replaced or cleaned, the fixing block 47 can be slid out of the square hole 44 along the slide rail 46, and then the fixing plate 45 can be slid out of the sliding plate 42. Finally, the wiping cloth can be removed. After the replacement is completed, the fixing plate 45 is put back on the sliding plate 42, and the fixing block 47 is slid into the square hole 44 to fix the fixing plate 45.

[0037] like Figure 5 As shown, the two connecting columns 41 are rubber columns. During the actual use of the device, when the operator holds the two handles 252 and moves toward the plate body 255, the connecting plate 21 will be driven to deviate outward. The rubber columns are elastic, so that the two connecting columns 41 are twisted, but the sliding plate 42 and the fixed plate 45 remain stable and do not deviate to the rear.

[0038] During the implementation process, a button switch in the prior art is also provided on the fixed box 253, model: PBS-33B small round button switch, the negative pole of the battery is directly connected to one of the input ends of the lighting lamp 31 using a wire, and the other end of the lighting lamp 31 is connected to the positive pole of the battery through a wire, and the button switch is placed on one of the guides, and the wire is turned on and off by the button switch.

[0039] It should be noted that the specific installation method of the lighting lamp 31 and the battery compartment 5, the circuit connection method and the control method used in the present invention are all conventional designs and will not be elaborated in detail in the present invention.

[0040] The working principle of the present invention is as follows: first, the device is brought to the surveying site and placed in a suitable position. In the initial state, the moving assembly 2 is tightly fitted with the scale 11, and the two are in a relatively static state. When the lighting position of the level scale needs to be adjusted, the operator holds the two handles 252 with his hands and moves the two handles 252 toward the plate body 255, and then the push plate 251 drives the connecting plate 21 to rotate, and the angle between the connecting plate 21 and the push plate 251 changes from a right angle to an obtuse angle, and the moving assembly 2 is no longer tightly fitted with the scale 11, and then the operator continues to hold the handles 252 and pushes the handles 252 with his hands. The support plate 24 drives the moving assembly 2 to move in the vertical direction under the guidance of the rotating shaft 13. At this time, the lighting lamp 31 fixed to the front side of the connecting plate 21 is also moving to illuminate the scale 11. The reflector 32 can reflect the light emitted by the lighting lamp 31, so that the light distribution on the level scale is more uniform. When the lighting lamp 31 is moved to the appropriate position, the operator releases the handle 252. The handle 252 and the push plate 251 move in the opposite direction under the action of the spring 254, so that the moving assembly 2 and the scale 11 are tightly fitted again, fixing the position of the moving assembly 2 on the scale 11 for easy reading.

[0041] At the same time, when the moving component 2 is moving, the connecting plate 21 drives the sliding plate 42 and the fixed plate 45 to move through the connecting column 41. The rear end of the fixed plate 45 is fixed with a rag by Velcro. During the movement of the fixed plate 45, the rag cleans the surface of the level scale. When the rag needs to be replaced or cleaned, the fixed block 47 can be slid out of the square hole 44 along the slide rail 46, and then the fixed plate 45 can be slid out of the sliding plate 42. Finally, the rag can be removed. After the replacement is completed, the fixed plate 45 is put back on the sliding plate 42, and the fixed block 47 is slid into the square hole 44 to fix the fixed plate 45.
