[0002] Measurement work is ubiquitous and crucial in various production, construction, scientific research, and daily life scenarios in modern society. Whether it's the construction of large-scale infrastructure or the precision processing of micro-products, accurate measurement data is highly essential to ensure the smooth progress of projects and the quality of results.

[0003] Meanwhile, the patent specification with application number CN221593861U discloses a multifunctional measuring ruler, "including: a detection component; an adsorption component is provided at the end of the detection component, and a positioning component is provided on the outer wall of the hinge position of the detection component. The detection component is set as two sets that are hinged to each other, so that the measuring ruler can swing and unfold to achieve a large span measurement. It also has the function of erecting one set of detection components to achieve the measurement of right angles. The positioning component provided at the outer end of the hinge position of the detection component can fix the angle of the detection component. The reference component can realize the comparative observation of the angle swing. The measuring component is installed at the hinge position of the detection component to facilitate the measurement of longer lengths."

[0004] When measuring excessively long distances, most existing measuring rulers use telescopic rulers or tape measures. The tape measure is prone to bending or twisting during stretching and contraction, which impairs measurement accuracy. The inner size of the telescopic ruler is smaller than the outer size, causing the measuring ruler to not fit snugly against the object's surface during measurement, resulting in measurement errors. Secondly, most existing measuring rulers do not have marking rods. When it is necessary to quickly mark and record measurement data, users have to find additional marking tools, which not only wastes time but also easily affects the accuracy of measurement results due to inaccurate marking positions.

[0005] Therefore, a multifunctional measuring ruler is proposed to address the above problems. Utility Model Content

[0006] To address the problems mentioned in the background art, this utility model provides a multifunctional measuring ruler, which effectively improves measurement accuracy, facilitates storage, enhances measurement efficiency, and ensures the accuracy and convenience of recording measurement results.

[0007] To achieve the above objectives, this utility model provides the following technical solution: a multifunctional measuring ruler, comprising a measuring ruler one, a measuring ruler two rotatably connected to one end of the measuring ruler one, and graduations engraved on both sides of one end of the measuring ruler one and one end of the measuring ruler two. A rectangular groove is provided at one end of the measuring ruler one, and two fixed rods are fixedly connected to the lower inner wall of the rectangular groove. Moving blocks are slidably connected to the inner surfaces of the two fixed rods, and return springs are fixedly connected to the opposite ends of the two moving blocks. The opposite ends of the two return springs are respectively fixedly connected to the inner walls of one side of the two fixed rods.

[0008] Preferably, each of the two movable blocks has a locking block 1 fixedly connected to one end of its corresponding side. Both locking blocks 1 are hemispherical. The top of the measuring ruler 2 is fixedly connected to a locking block 2. The outer surface of the locking block 2 is provided with a circular groove for use with the two locking blocks 1.

[0009] Preferably, two guide blocks are fixedly connected to the outer surfaces of the two movable blocks, and guide grooves are provided on the inner surfaces of the two fixed rods to cooperate with the two guide blocks.

[0010] Preferably, the end of the measuring ruler one that is in contact with the measuring ruler two is coated with a magnetic coating, and the end of the measuring ruler two that is in contact with the measuring ruler one is made of iron.

[0011] Preferably, both ends of the measuring ruler one and the measuring ruler two are fixedly connected with four elastic pads, and all four elastic pads are made of rubber.

[0012] Preferably, both measuring ruler one and measuring ruler two have two marking rods that are damped and slidably connected at the graduated end.

[0013] Preferably, one end of each of the four marking rods is provided with a sliding groove, and one end of each of the measuring ruler one and measuring ruler two is provided with a sliding strip for use with the sliding groove.

Detailed Implementation

[0023] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0024] like Figures 1 to 5As shown, this utility model provides a multifunctional measuring ruler, including a measuring ruler 1, with a measuring ruler 2 rotatably connected to one end of the measuring ruler 1. Both ends of the measuring ruler 1 and the measuring ruler 2 are engraved with scales 5. The rotatable connection structure of the measuring ruler 1 and the measuring ruler 2 allows the measuring ruler to flexibly change its shape according to measurement needs, increasing the applicability of the measurement. The scales 5 on both sides facilitate reading data from different directions, improving the convenience of measurement. A rectangular groove 7 is opened at one end of the measuring ruler 1. Two fixed rods 73 are fixedly connected to the lower inner wall of the rectangular groove 7. Moving blocks 76 are slidably connected to the inner surfaces of the two fixed rods 73. Return springs 71 are fixedly connected to the opposite ends of the two moving blocks 76. The opposite ends of the two return springs 71 are respectively fixedly connected to the inner wall of one side of the two fixed rods 73. The combination of the fixed rods 73, moving blocks 76 and return springs 71 in the rectangular groove 7 provides a basis for subsequent length adjustment.

[0025] Specifically, each of the two moving blocks 76 has a corresponding locking block 75 fixedly connected to one end. Both locking blocks 75 are hemispherical. The top of the measuring ruler 2 is fixedly connected to a locking block 13. The outer surface of the locking block 13 has a circular groove 12 that cooperates with the two locking blocks 75. Under the action of the return spring 71, the measuring ruler 1 and the measuring ruler 2 can be stably locked and fixed, ensuring that the angle will not easily change during the measurement process, thus improving the accuracy and reliability of the measurement.

[0026] like Figures 1 to 5 As shown, two guide blocks 74 are fixedly connected to the outer surfaces of the two moving blocks 76, and guide grooves 72 are provided on the inner surfaces of the two fixed rods 73 to cooperate with the two guide blocks 74. This effectively restricts the sliding direction of the moving blocks 76, so that the first locking block 75 can engage or disengage with the second locking block 13 more smoothly and accurately during the movement.

[0027] Furthermore, the end of measuring ruler 1 that is in contact with measuring ruler 2 is coated with magnetic coating 4, and the end of measuring ruler 2 that is in contact with measuring ruler 1 is made of iron. When no extension is needed for measurement, it is easy to retract the measuring ruler and also easy to store.

[0028] like Figures 1 to 5 As shown, both ends of measuring ruler 1 and measuring ruler 2 are fixedly connected with four elastic pads 3. All four elastic pads 3 are made of rubber. The rubber elastic pads 3 have good cushioning performance. When the measuring ruler comes into contact with the object being measured, they can effectively prevent the end of the measuring ruler from scratching the surface of the object and protect the object being measured.

[0029] It is worth noting that both measuring ruler 1 and measuring ruler 2 have two marking rods 14 with damped sliding connection at the end with the scale 5, which allows them to slide smoothly on the measuring ruler and stop at the desired scale 5 position. This makes it convenient for users to mark key positions such as the start and end points of the measurement without the need for other tools. This facilitates direct data recording and marking during the measurement process, improves the convenience and efficiency of the measurement operation, and reduces measurement errors caused by cumbersome marking operations.

[0030] like Figures 1 to 5 As shown, each of the four marking rods 14 has a groove 141 at one end, and each of the measuring rulers 1 and 2 has a slider 6 that works with the groove 141 at one end. The slider 6 has a "convex" shaped cross section, and both ends of the two sliders 6 are fixedly connected to a limiting plate 11. The structural design of the groove 141, the "convex" shaped slider 6, and the limiting plate 11 ensures that the marking rod 14 can only slide stably along the slider 6, effectively preventing the marking rod 14 from accidentally slipping off the measuring ruler, ensuring the stability and reliability of the marking rod 14 during use, and further improving the accuracy and convenience of the measurement operation.

[0031] The structure of the electric motor is existing technology and will not be described in detail. Additionally, this utility model also includes a power supply, controller, and switch, which are not the main technical points of this patent and will not be described in detail. The wiring diagram of the motor in this utility model is common knowledge in the field, and its working principle is already known technology. The appropriate model is selected based on actual use; therefore, the control method and wiring layout of the motor will not be explained in detail.

[0032] Working principle and process: When the length of the ruler needs to be increased, simply rotate measuring ruler 2 to make it rotate around the rotation connection point with measuring ruler 1. When measuring ruler 2 rotates to the target position, due to the circular groove 12 on the outer surface of the locking block 2 13, during the rotation of measuring ruler 2, locking block 1 75 will gradually approach and lock into the circular groove 12 of locking block 2 13 under the influence of its own spherical characteristics, thereby stabilizing and fixing measuring ruler 1 and measuring ruler 2 at the new angular position, realizing the increase of the ruler length. The rubber elastic pads 3 at both ends of measuring ruler 1 and measuring ruler 2 can play a buffering and protective role when the ruler comes into contact with the object being measured, preventing scratches on the object surface, and can better fit when measuring irregular objects; while the two marking rods 14 at one end of measuring ruler 1 and measuring ruler 2 can conveniently mark the starting point, ending point and other key positions during measurement, which is convenient for subsequent data recording and processing.
