Description

Technical Field

[0001] This utility model relates to the field of engineering surveying equipment technology, and more specifically to a leveling rod with a night lighting auxiliary mechanism. Background Technology

[0002] In engineering surveying, the leveling rod is an important tool for measuring the elevation difference between two points. However, in practice, surveying work often needs to be carried out at night or in dimly lit environments, such as tunnel construction surveying and nighttime road engineering surveying. Currently, traditional leveling rods do not have built-in lighting functions. During nighttime measurements, surveyors typically need to assign additional personnel to hold a handheld lighting tool to illuminate the leveling rod. This not only increases labor costs but also results in unstable lighting, easily affected by factors such as the shake of the person holding the rod, making it difficult to guarantee measurement accuracy. Furthermore, existing temporary lighting aids, such as simply using a flashlight, suffer from problems such as difficulty in adjusting the lighting angle and uneven light distribution, failing to meet the requirements of clear readings from the leveling rod for high-precision measurements. Therefore, designing a leveling rod with a nighttime lighting auxiliary mechanism that is convenient to use at night, provides stable illumination without compromising measurement accuracy, is of significant practical importance. Utility Model Content

[0003] The technical problem to be solved by this utility model is to provide a leveling rod with a night lighting auxiliary mechanism to solve the problems of inconvenient lighting and reduced measurement accuracy of existing leveling rods during nighttime measurements, so as to achieve efficient and accurate nighttime measurements.

[0004] To solve the above-mentioned technical problems, the technical solution adopted by this utility model is as follows.

[0005] A leveling ruler with a nighttime lighting auxiliary mechanism includes a ruler body and graduation marks on the front of the ruler body. The ruler body is equipped with a lighting mechanism via a clamping assembly for illuminating the graduation marks. The lighting mechanism includes a lighting base located on the side of the clamping mechanism and a lamp body connected to the lighting base via a flexible tube. The lighting base contains a battery compartment housing a storage battery. The lighting base has a switch button for turning the lighting on and off, a charging port for charging the storage battery, and a brightness adjustment knob for adjusting the lighting brightness. The charging port is connected to the input end of the storage battery, and the output end of the storage battery is connected to the input end of the lamp body. The switch button and the brightness adjustment knob are connected in series on a connecting wire between the storage battery and the lamp body.

[0006] To further optimize the technical solution, the clamping assembly includes a fixed seat and a movable seat that are inserted together at one end. The fixed seat and the movable seat are combined to form a U-shaped clamping seat for clamping the ruler. An adjustment groove is provided on the side of the fixed seat facing the movable seat. The movable seat is inserted into the adjustment groove. Several fastening springs are provided between the inner end of the adjustment groove and the end face of the movable seat to tighten the movable seat and achieve clamping of the ruler.

[0007] To further optimize the technical solution, a clamping plate is provided on the inner side of the movable seat by fastening bolts, and an operating end for rotating the fastening bolts is provided at the outer end of the movable seat through which the fastening bolts pass.

[0008] To further optimize the technical solution, rubber pads are provided on the inner side of the fixing base and the clamping plate to increase the friction with the ruler body.

[0009] To further optimize the technical solution, grooves are provided on both sides of the fixed seat and the movable seat to facilitate opening the clamping assembly.

[0016] The present invention will now be described in further detail with reference to the accompanying drawings and specific embodiments.

[0017] A leveling rod with a nighttime lighting auxiliary mechanism, combined with Figure 1 As shown, the device includes a ruler body 1, with scale markings on its front side. An illumination mechanism is provided on the ruler body 1 via a clamping assembly to illuminate the scale markings.

[0018] The clamping assembly is detachably installed on the ruler body 1. The clamping assembly includes a fixed seat 2 and a movable seat 3 that are inserted together at one end. The fixed seat 2 and the movable seat 3 are combined to form a U-shaped clamping seat for clamping the ruler body 1. An adjustment groove 4 is provided on the side of the fixed seat 2 facing the movable seat 3. The movable seat 3 is inserted into the adjustment groove 4. Several fastening springs 5 ​​are provided between the inner end of the adjustment groove and the end face of the movable seat 3 to tighten the movable seat and achieve clamping of the ruler body.

[0019] A clamping plate 7 is installed on the inner side of the movable seat 3 via a fastening bolt 8. An operating end 9 is located at the outer end of the movable seat 3, through which the fastening bolt is rotated to fine-tune the clamping of the ruler. When the fixed seat and movable seat are not clamped tightly, the position of the clamping plate is adjusted by rotating the fastening bolt to clamp the ruler, accommodating rulers of different sizes. Rubber pads 6 are installed on the inner side of the fixed seat 2 and on the clamping plate 7 to increase the friction between the fixed seat 2 and the ruler, improving the stability of the clamping assembly and preventing frictional damage to the ruler surface.

[0020] Both the fixed base 2 and the movable base 3 have grooves 10 on both sides, which makes it convenient for operators to open the clamping components and realize the quick installation and disassembly of the clamping components, thereby realizing the quick assembly and disassembly of the lighting mechanism.

[0021] The lighting mechanism includes a lighting base 11 located on one side of the fixed base 2 and a lamp body connected to the lighting base via a flexible hose 12. The lighting base 11 contains a battery compartment housing a storage battery for storing electrical energy. The storage battery is removable and can be replaced when its power is low to ensure the normal operation of the level. The lighting base 11 is equipped with a switch button 16, a charging port 17, a brightness adjustment knob 18, and a power indicator light 19. The switch button 16 is used to turn the lighting on and off, the charging port 17 is used to charge the storage battery, the brightness adjustment knob 18 is used to adjust the lighting brightness, and the power indicator light 19 displays the battery's power level. The charging port is connected to the input terminal of the storage battery, and the output terminal of the storage battery is connected to both the lamp body and the input terminal of the power indicator light. The switch button and the brightness adjustment knob are connected in series on the connecting wire between the storage battery and the lamp body.

[0022] The lamp body includes a lamp holder 13 connected to a flexible tube 12. Several LED beads 14 are mounted on the lamp holder 13, and a lamp cover 15 is provided on the lamp holder 13 to protect the LED beads. The position and angle of the light beam can be adjusted via the flexible tube.

[0023] In use, this invention opens the clamping assembly by pulling the movable seat outward, clamping it at a suitable position on the leveling scale. If the scale is not securely clamped, the tightening bolt is rotated inward via the operating end to secure the clamping plate against the scale, thus fixing the lighting mechanism in place. During illumination, the lamp's position and angle are adjusted via the flexible tube to align the lamp with the scale area of ​​the leveling scale for optimal lighting. The brightness is adjusted according to light intensity, improving the accuracy of nighttime measurements. When the battery is low, it is recharged via the charging port.

[0024] After the measurement is completed, pull out the fixed base and the movable base to remove the clamping assembly from the leveling rod. This will allow you to disassemble the lighting assembly and make it easier to store and preserve the leveling rod and the lighting assembly.
