Description

Technical Field

[0001] The utility model relates to the technical field of elevation measurement and setting out, in particular to a level rod which is convenient for elevation measurement and setting out. Background Art

[0002] A tower ruler is a type of level ruler. Early levels were mostly made of wood, which was heavy and limited in length, making it inconvenient to carry when measuring. Later, it was gradually made of lightweight and high-strength materials such as aluminum alloy. It adopts a tower-shaped retractable form, which is easy to pull out when in use. The range of single elevation measurement is greatly improved. The length is generally 5m, and it can be retracted when carried. Because its shape is similar to a tower, it is often called a tower ruler.

[0003] The existing tower ruler measures the height of an object by telescoping. However, when the horizontal length of an object at a height needs to be measured, the operator needs to climb up to measure, which results in slow measurement speed and troublesome measurement. Therefore, a level ruler that is convenient for elevation measurement and setting out is proposed to solve the above problems. Utility Model Content

[0004] In order to achieve the above-mentioned purpose of the utility model and address the above-mentioned technical problems, the utility model provides a level rod that is convenient for elevation measurement and setting out.

[0005] The technical solution comprises a ruler with a linkage plate rotatably connected to its upper end. A limit cylinder is fixedly mounted on the upper end of the linkage plate, and a telescopic ruler is inserted into the interior of the limit cylinder. The ruler is also provided with a rotation slot on its side. Through the rotatable connection between the linkage plate and the ruler, the telescopic ruler can be raised to measure the horizontal length of elevated objects, eliminating the need for operators to ascend for measurement and improving the safety and convenience of the operation. Furthermore, this design makes the measurement process faster and reduces the workload of operators.

[0006] A limit plate is fixed to one side of the ruler, located below the rotating groove. The limit plate enhances the stability of the ruler, ensures accuracy and reliability during measurement, and reduces measurement errors caused by ruler movement.

[0007] A baffle is fixed to the other end of the base ruler opposite to the limit plate. The setting of the baffle provides additional fixation and support, making the base ruler more stable during use and reducing measurement errors caused by unstable base ruler.

[0008] The inner surface of the stopper is provided with friction protrusions that contact the surface of the telescopic ruler. These protrusions increase the friction of the ruler within the stopper, preventing it from slipping during measurement. The friction protrusions enhance the ruler's stability within the stopper, ensuring measurement accuracy and reducing errors caused by ruler slippage.

[0009] The upper end of the bottom ruler is fixed with an arc plate, which is rotatably connected to the linkage plate. The design of the arc plate provides better flexibility and operability, making the measurement process smoother and improving measurement efficiency.

[0010] The beneficial effects of the technical solution provided by the embodiment of the utility model are:

[0011] (1) Improve work efficiency: The linkage plate is connected to the bottom ruler in a rotating manner, so that the telescopic ruler can be lifted up to measure the horizontal length of high objects, avoiding the need for operators to climb up to measure. The horizontal length measurement of high objects can be completed quickly, greatly shortening the measurement time and improving work efficiency.

[0012] (2) Reduce safety risks: It avoids the risk of workers working at heights and reduces the safety accidents that may be caused by high-altitude operations;

[0013] (3) Enhanced durability: The friction ridge design between the telescopic ruler and the limit cylinder increases service life and reduces wear caused by frequent use;

[0014] (4) Improve measurement accuracy: The design of the limit plate and baffle ensures the stability of the ruler during use, reduces the measurement error caused by the movement of the ruler, and improves the measurement accuracy;

[0015] (5) Easy to carry and store: Due to the compact design of the base ruler and telescopic ruler, the entire level ruler is easy to carry and store, making it convenient for operators to quickly transfer between different locations;

[0016] (6) Cost-effectiveness: Compared with traditional elevation measurement tools, the design of this level rod reduces production costs while improving usage efficiency, resulting in a better cost-effectiveness ratio. BRIEF DESCRIPTION OF THE DRAWINGS
