Description

Technical Field

[0001] This utility model relates to the field of horizontal measuring ruler technology, and in particular to an adjustable length horizontal measuring ruler. Background Technology

[0002] A level is a precision measuring tool used to detect and measure the levelness, verticality, or tilt angle of an object's surface. It is widely used in construction, decoration, machinery installation, and equipment debugging. Its core principle is to utilize the fluidity of air bubbles in a liquid (such as bubble levels) or electronic sensors (such as digital displays) to convert minute tilts of the measured surface into intuitively readable signals. Traditional bubble levels typically include multiple bubble levels for horizontal, vertical, and 45° angles, while digital levels display the angle values ​​directly on a screen. It ensures that objects (such as walls, floors, pipes, and machine tools) are in the designed horizontal or vertical position during construction or installation, making it a key tool for guaranteeing project quality and equipment accuracy. However, the existing level measuring scales mostly use an integrated or complex bolt-fixed structure for the bubble level chamber. When the bubble level needs to be replaced due to aging or impact, the staff needs to use professional tools to disassemble multiple fixing parts. The disassembly process is time-consuming, and the installation requires precise alignment and positioning. Moreover, there is a lack of convenient locking and fixing mechanisms, which can easily affect the measurement accuracy again due to improper installation. This makes it difficult and inefficient to replace the bubble level chamber, affecting the overall efficiency of the equipment. In addition, the existing equipment has a limited single ruler length, which cannot meet the needs of long-distance measurement. Therefore, we propose an adjustable-length horizontal measuring ruler to solve the above problems. Utility Model Content

[0003] To achieve the above objectives, the present invention adopts the following technical solution: An adjustable length horizontal measuring ruler includes a measuring ruler body. Two device holes are opened on one side of the measuring ruler body, respectively near both ends of the measuring ruler body. Three mounting slots are opened on the top of the measuring ruler body. Each of the three mounting slots has a mounting shell inside, and a detachable fixing plate is snapped into the inner side of each of the three mounting slots. Auxiliary slots are opened on the bottom of each of the three mounting shells. Guide chambers are opened on the inner walls of both sides of each of the three auxiliary slots. Guide posts are fixedly installed on the inner wall of one side of each of the six guide chambers.

[0004] Specifically, two magnetic positioning posts are fixedly installed on the left end of the measuring ruler body, and two magnetic positioning slots are opened on the right end of the measuring ruler body. The two magnetic positioning posts are respectively adapted to the corresponding magnetic positioning slots. When it is necessary to extend the measuring length, the magnetic positioning post of one measuring ruler body can be inserted into the magnetic positioning slot of the other measuring ruler body, and the splicing can be achieved quickly and accurately through magnetic force, while ensuring the overall straightness of the spliced ​​part.

[0005] Specifically, a combination pin is provided on one side of the measuring ruler body, and two columnar protrusions are provided on one side of the combination pin. The two columnar protrusions are respectively adapted to the corresponding equipment holes. The combination pin is made with an integrated molding process, which makes the structure sturdy and durable. After multiple measuring ruler bodies are spliced ​​together, the columnar protrusions of the combination pin are inserted into the corresponding equipment holes, which can further strengthen the connection strength at the splicing point, prevent relative displacement during the measurement process, and improve the accuracy of the measurement.

[0006] Specifically, two magnetic adsorption strips are fixedly installed on one side of the measuring ruler body. When measuring the surface of a metal object, the measuring ruler body can be firmly adsorbed onto the object without manual holding, freeing the operator's hands and facilitating reading and recording.

[0007] Specifically, each of the three mounting housings has an opening on one side, and a silicone damping frame is fixedly installed inside each of the three openings. A bubble level chamber is fixedly installed inside each of the three silicone damping frames. The bubble level chamber contains a special liquid and bubbles. The position of the bubbles indicates whether the measuring surface is level. The silicone damping frame makes the bubble level chamber more stable inside the mounting housing, preventing shaking from affecting the measurement accuracy.

[0008] Specifically, each of the six guide chambers has a slidable limit clamp installed on its inner side. Each of the six limit clamps is slidably sleeved on its corresponding guide post. Each of the six guide posts has a limit spring sleeved on its outer side. The two ends of each of the six limit springs are fixedly connected to one end of the corresponding limit clamp and one side inner wall of the guide chamber. The other end of each of the six limit clamps is designed as a bevel. The bevel design makes it easy to push the limit clamp during installation or disassembly, reducing resistance.

[0009] Specifically, a fixed base is fixedly installed on the bottom inner wall of each of the three mounting slots, a fixed post is fixedly installed on the top of each of the three fixed bases, a positive conical metal block is fixedly installed on the top of each of the three fixed posts, and a reverse conical metal block is slidably fitted on the outer side of each of the three fixed posts. A groove is opened on the top of each of the three reverse conical metal blocks, and the three grooves are respectively adapted to the corresponding positive conical metal blocks. When the top of the reverse conical metal block abuts against the bottom of the positive conical metal block, the positive conical metal block and the groove cooperate with each other, which allows the two limiting clamps to disengage from the positive conical metal block and the reverse conical metal block without obstruction.

[0010] Specifically, multiple support springs are provided on the inner side of each of the three mounting slots. Each set of four support springs is composed of alloy plates on the upper and lower sides of each set of support springs. Damping pads are fixedly installed on the bottom of the alloy plate located above the support springs. The bottom of each set of support springs is fixedly connected to the top of the corresponding alloy plate, and the top of each set of support springs is fixedly connected to the bottom of the corresponding damping pad. Through the combined action of the support springs and damping pads, the impact of external impacts on the internal components of the mounting slots can be effectively reduced, thereby improving the service life and stability of the equipment. It can also assist in the disassembly of the mounting shell.

[0011] Compared with the prior art, the beneficial effects of this utility model are as follows: by setting fixed insert plates, mounting shells and limiting clips, etc., the limiting clips are driven to move radially along the guide column by pressing or pulling, and the limiting spring rebounds and contacts the positive and negative conical metal blocks for positioning, which simplifies the disassembly and installation steps of the horizontal bubble chamber, solves the problem of difficult replacement, and can be assembled by magnetically fixing the magnetic positioning column and positioning groove and positioning the combination pin by inserting it into the equipment hole, thus solving the measurement limitation of insufficient single-foot length.

[0014] Reference Figure 1-6 An adjustable length horizontal measuring ruler includes a measuring ruler body 1. Two device holes 2 are opened on one side of the measuring ruler body 1, and the two device holes 2 are respectively close to the two ends of the measuring ruler body 1. Three mounting slots are opened on the top of the measuring ruler body 1. The inner side of each of the three mounting slots is provided with a mounting shell 8. A detachable fixing plate 7 is snapped into the inner side of each of the three mounting slots. The bottom of each of the three mounting shells 8 is provided with an auxiliary slot. Guide chambers are opened on the inner walls of both sides of each of the three auxiliary slots. Guide posts 16 are fixedly installed on the inner wall of one side of each of the six guide chambers. The guide posts 16 are made of stainless steel and the surface is smoothed to effectively reduce the friction when the parts slide.

[0015] In this embodiment, two magnetic positioning posts 3 are fixedly installed on the left end of the measuring ruler body 1, and two magnetic positioning slots 4 are opened on the right end of the measuring ruler body 1. The two magnetic positioning posts 3 are respectively adapted to the corresponding magnetic positioning slots 4. When it is necessary to extend the measuring length, the magnetic positioning post 3 of one measuring ruler body 1 can be inserted into the magnetic positioning slot 4 of the other measuring ruler body 1, and the splicing can be achieved quickly and accurately through magnetic force, while ensuring the overall straightness after splicing.

[0016] In this embodiment, a combination pin 6 is provided on one side of the measuring ruler body 1. Two columnar protrusions are provided on one side of the combination pin 6. The two columnar protrusions are respectively adapted to the corresponding equipment holes 2. The combination pin 6 is made with an integrated molding process, and the structure is sturdy and durable. After multiple measuring ruler bodies 1 are spliced ​​together, the columnar protrusions of the combination pin 6 are inserted into the corresponding equipment holes 2, which can further strengthen the connection strength at the splicing point, prevent relative displacement during the measurement process, and improve the accuracy of the measurement.

[0017] In this embodiment, two magnetic adsorption strips 5 are fixedly installed on one side of the measuring ruler body 1. When measuring the surface of a metal object, the measuring ruler body 1 can be firmly adsorbed onto the object without manual hand-holding, freeing the operator's hands and facilitating reading and recording.

[0018] In this embodiment, each of the three mounting housings 8 has an opening on one side, and a silicone damping frame 9 is fixedly installed inside each of the three openings. A bubble level chamber 10 is fixedly installed inside each of the three silicone damping frames 9. The bubble level chamber 10 contains a special liquid and bubbles. The position change of the bubbles indicates whether the measuring surface is level. The silicone damping frame 9 makes the bubble level chamber 10 more stable inside the mounting housing 8, avoiding the impact of shaking on the measurement accuracy.

[0019] In this embodiment, a limiting clip 15 is slidably installed on the inner side of each of the six guide chambers. The six limiting clips 15 are slidably sleeved on the corresponding guide post 16. A limiting spring 17 is sleeved on the outer side of each of the six guide posts 16. The two ends of the six limiting springs 17 are fixedly connected to one end of the corresponding limiting clip 15 and one side inner wall of the guide chamber, respectively. The other end of each of the six limiting clips 15 is set as an inclined surface. The inclined surface design facilitates the smooth pushing of the limiting clip 15 during installation or disassembly, reducing resistance.

[0020] In this embodiment, a fixed base 11 is fixedly installed on the bottom inner wall of each of the three mounting slots, a fixed post 12 is fixedly installed on the top of each of the three fixed bases 11, a positive conical metal block 13 is fixedly installed on the top of each of the three fixed posts 12, and a reverse conical metal block 14 is slidably sleeved on the outer side of each of the three fixed posts 12. A groove is opened on the top of each of the three reverse conical metal blocks 14, and the three grooves are respectively adapted to the corresponding positive conical metal blocks 13. When the top of the reverse conical metal block 14 abuts against the bottom of the positive conical metal block 13, the positive conical metal block 13 and the groove cooperate with each other, which can facilitate the two limiting clips 15 to disengage from the positive conical metal block 13 and the reverse conical metal block 14 without obstruction.

[0021] In this embodiment, multiple support springs 20 are provided on the inner side of each of the three mounting slots. Each set of four support springs 20 is a group. Alloy plates 18 are provided on the upper and lower sides of each group of support springs 20. Damping pads 19 are fixedly installed on the bottom of the alloy plate 18 located above the support springs 20. The bottom end of each group of support springs 20 is fixedly connected to the top of the corresponding alloy plate 18, and the top end of each group of support springs 20 is fixedly connected to the bottom of the corresponding damping pad 19. Through the combined action of the support springs 20 and the damping pads 19, the impact of external impact on the internal components of the mounting slot can be effectively reduced, thereby improving the service life and stability of the equipment. It can also assist in the disassembly of the mounting shell 8.

[0022] Working principle: When measuring a metal surface, the operator can place the measuring ruler body 1 close to the surface and attach it to the metal surface via the two magnetic strips 5 on its back, thus eliminating the need for hand support and freeing up the operator's hands. When the length of a single measuring ruler body 1 is insufficient for length measurement, the operator can assemble two or more measuring ruler bodies 1. The two magnetic positioning pins 3 on the left end of one measuring ruler body 1 are inserted into the two magnetic positioning slots 4 on the right end of another measuring ruler body 1 for magnetic fixation. Then, the operator inserts the combination pins 6 into the two adjacent equipment holes 2 of the two measuring ruler bodies 1 to complete the positioning and enhance the stability of the connection. When the bubble level 10 has errors and needs to be replaced, the operator first manually... The fixing plate 7 is removed, and then the mounting shell 8 is pressed down. The mounting shell 8 moves downward under force, compressing the multiple support springs 20 and simultaneously causing the two limiting clips 15 to move downward. The two limiting clips 15 move downward and contact the same reverse conical metal block 14. The sides of the two limiting clips 15 that contact the same reverse conical metal block 14 are both inclined surfaces. The two limiting clips 15 are slidably sleeved on the corresponding guide posts 16. After being compressed, the two limiting clips 15 move radially along the corresponding guide posts 16. At the same time, the two limiting springs 17 are compressed, and the two limiting clips 15 move downward with the mounting shell 8 to the middle position of the reverse conical metal block 14. At this time, the reverse conical metal block 14 does not move towards the two... When pressure is applied to the two limit clamps 15, they are respectively pushed back by the corresponding limit springs 17. At this time, the two limit clamps 15 abut against the same reverse conical metal block 14. While the multiple support springs 20 apply a rebound force to the mounting housing 8, the operator manually pulls the mounting housing 8 upward. At this time, the two limit clamps 15 clamp the same reverse conical metal block 14 and move it upward. The top of the reverse conical metal block 14 abuts against the forward conical metal block 13. The top of the reverse conical metal block 14 has a groove, and the forward conical metal block 13 is adapted to the groove. Therefore, the reverse conical metal block 14 and the forward conical metal block 13 are combined at this time, and the two limit clamps 15 follow the mounting housing 8 upward. When the device slides across the surfaces of the reverse conical metal block 14 and the forward conical metal block 13, it can easily detach. After the housing 8 and the two limiting clips 15 are disassembled, the reverse conical metal block 14 falls back to its original position. When the housing 8 is installed, the housing 8 moves the two limiting clips 15 downward. The two limiting clips 15 come into contact with the same forward conical metal block 13 and retract under force. When the two limiting clips 15 are moved to the bottom of the forward conical metal block 13, they are reset by the rebound force of the corresponding limiting springs 17. The top of the two limiting clips 15 is flat and comes into contact with the bottom of the forward conical metal block 13 to complete the fixed clamping. Then the staff can reset the fixing plate 7 to complete the installation.

[0023] The technological advancements of this invention compared to existing technologies are as follows: the limiting clamp 15 can be moved radially along the guide post 16 by pressing or pulling, and the limiting spring 17 rebounds and contacts the positive conical metal block 13 and the reverse conical metal block 14 for positioning, simplifying the disassembly and installation steps of the horizontal bubble chamber 10, solving the problem of difficult replacement, and the multi-foot assembly can be achieved by magnetically fixing the magnetic positioning post 3 and the magnetic positioning groove 4, and by inserting the combination pin 6 into the equipment hole 2 for positioning, thus avoiding the measurement limitations of insufficient single-foot length.
