Description

Technical Field

[0001] The utility model relates to the technical field of measuring tower rulers, in particular to a movable measuring tower ruler used for nighttime measurement. Background Art

[0002] The surveying and mapping level ruler belongs to the surveying and mapping instrument and is a type of level ruler. It is generally used in conjunction with a level and a theodolite. It is mainly used to measure terrain height and provide reliable data for engineering construction. The commonly used level ruler is mainly used for measurement work under well-lit conditions. When the light is weak, the data is difficult to judge because the scales and markings on the level ruler are not clear. It is impossible to accurately judge the scale of the level ruler, resulting in errors in the measurement data results. There is now a tower ruler on the market that uses a light-emitting diode on the top to illuminate the ruler surface. It has the disadvantages of concentrated light source and uneven illumination on the ruler surface. Based on this, a movable measuring tower ruler for night measurement is designed. Through the cooperation of the ruler surface, light-emitting diodes and reflectors, the efficiency of light use is improved, and the measurement and observation effect is good. Utility Model Content

[0003] The purpose of the utility model is to overcome the shortcomings of the prior art and provide a movable measuring tower ruler for nighttime measurement. The toothed block and the rectangular slot cooperate with each other to fix the ruler surface to prevent it from displacement and affecting the measurement accuracy. A transparent acrylic ruler surface is used to form a light guide plate. The ruler surface, the light emitting diode and the reflector cooperate with each other to improve the efficiency of light use. Under the condition of equal area luminous brightness, the luminous efficiency is high and the power consumption is low. It is very suitable for nighttime use and has good measurement and observation effects.

[0004] The purpose of the utility model is achieved through the following technical solutions: a movable measuring tower ruler for nighttime measurement, the measuring tower ruler comprising a tower ruler, a scale body provided with scales, a plurality of toothed blocks provided inside the tower ruler, a scale surface of the tower ruler provided with rectangular slots matched with the toothed blocks, a top portion of the toothed blocks partially passes through the rectangular slots, a lamp bead is provided between the portion of the toothed blocks that is not passed through and the scale surface, a laser engraved marking scale and numbers are provided on the scale surface, a light emitting diode and a reflector are further provided inside the tower ruler, and the scale surface is provided between the light emitting diode and the reflector.

[0005] Furthermore, the tower ruler is composed of a plurality of ruler bodies connected by plugging, and each ruler body is provided with a rectangular slot, which are fixed to each other by toothed blocks.

[0006] Furthermore, a power storage chamber is provided inside the tower ruler body, a battery is installed in the power storage chamber, and the battery is connected to the light emitting diode.

[0007] Furthermore, the storage battery is a rechargeable and replaceable lithium battery.

[0008] Furthermore, the light emitting diode and the battery are provided with a switch, and the switch is arranged on the outer wall of the power storage chamber to control the on and off of the light emitting diode.

[0009] Furthermore, the ruler surface is made of transparent acrylic material to form a light guide plate, and the tower ruler is made of aluminum alloy. The light guide plate is made of optical-grade acrylic / PC sheet, and then a high-tech material with extremely high refractive index and no light absorption is used to print light guide points on the bottom surface of the optical-grade acrylic sheet by laser engraving, V-shaped cross grid engraving, and UV screen printing technology. The optical-grade acrylic sheet is used to absorb the light emitted from the light-emitting diode and stay on the surface of the optical-grade acrylic sheet. When the light hits each light guide point, the reflected light will diffuse to various angles, and then destroy the reflection condition and be emitted from the front of the light guide plate. Through various light guide points of different densities and sizes, the light guide plate can emit light evenly. A reflective sheet can also be set in the tower ruler. The purpose of the reflective sheet is to reflect the light exposed from the bottom surface back to the light guide plate to improve the efficiency of light use. Under the condition of equal area luminous brightness, the luminous efficiency is high and the power consumption is low.

[0010] Furthermore, a movable moving component is provided at the rear bottom of the tower ruler.

[0011] Furthermore, the moving component includes an inverted T-shaped bracket and two rollers. The top end of the inverted T-shaped bracket is movably connected to the rear side of the tower ruler so that the inverted T-shaped bracket can rotate up and down around the connection point. The two rollers are respectively mounted on the left and right ends of the bottom of the inverted T-shaped bracket.

[0012] Furthermore, a handle is provided on one side of the tower ruler.

[0013] The beneficial effects of the utility model are:

[0014] 1. The utility model fixes the scale surface through the mutual cooperation between the toothed block and the rectangular slot to prevent it from displacement and affecting the measurement accuracy.

Under the condition of equal area luminous brightness, the luminous efficiency is high and the power consumption is low. It is very suitable for night use. The light emitted by the light-emitting diode reaches the right side of the tower scale along the scale surface, and is reflected by the reflector. The light on the entire scale surface is uniform and does not irritate the observer's eyes. The light passes through the laser-engraved marking scales and numbers to form luminous suspended markings and fonts, which has a good measurement and observation effect.
