Description

Technical Field

[0001] This utility model relates to the field of measuring ruler technology, and more specifically, to an adjustable building measuring ruler that can be locked quickly. Background Technology

[0002] Construction engineering refers to the physical engineering project formed by the construction of various buildings and their ancillary facilities and the installation of supporting lines, pipelines and equipment. It can only be realized through construction activities. During the implementation of construction engineering, measuring rulers are used for surveying work.

[0003] Currently, when measuring objects, institutions need to hold a measuring ruler by hand. However, when measuring manually, the hand is prone to slight tremors, making the marking work during measurement quite troublesome. In addition, the measuring ruler has a fixed size, which is not easy to adjust, thus reducing work efficiency.

[0004] A search revealed that Chinese patent CN218864919U discloses a portable and adjustable measuring ruler for construction engineering. In this structure, the telescopic ruler slides within a groove in the first ruler body. Pulling the fastening plate causes the telescopic ruler to pop out under spring action. A slider slides within a groove to assist in increasing the measurement length, meeting different needs and improving convenience and accuracy. Furthermore, the first and second ruler bodies are foldable via a mounting rod for easy storage and portability, saving space. Both the first and second ruler bodies are rotatable, and the rotation tension can be adjusted via a positioning seat, allowing for flexible angle adjustment according to the measurement scenario. A rubber suction cup at one end of the second ruler body, working with a piston rod to remove internal air, enhances suction force and allows for fixation to the object being measured, improving measurement stability. Both the first and second ruler bodies have graduation lines on one side for easy direct reading of measurement data, making operation simple and intuitive.

[0005] However, in actual use, the positioning seat can only adjust the tightness of the rotation between the first and second rulers, but lacks a precise angle positioning and locking mechanism. This makes it impossible to accurately adjust the angle between the first and second rulers, resulting in large errors in the measurement data and affecting subsequent construction operations and project quality. Utility Model Content

[0006] In order to overcome the above-mentioned defects of the prior art, the present invention provides a quick-locking adjustable building measuring ruler to solve the problems mentioned in the background art.

[0007] To achieve the above objectives, this utility model provides the following technical solution:

[0008] An adjustable building measuring ruler with quick locking includes a first ruler body, a connecting column fixedly provided on one side of the first ruler body, a second ruler body sleeved on the surface of the connecting column, limit plates fixedly provided at both ends of the connecting column, and a locking mechanism provided on one side of the second ruler body.

[0009] The locking mechanism includes an L-shaped fixing block fixedly disposed on one side of the second ruler body. The L-shaped fixing block has a sliding groove inside, and a cross slider is slidably disposed inside the sliding groove. A fixing plate is fixedly disposed at the bottom of the cross slider. A limit bar is fixedly disposed inside the fixing plate. A spring is sleeved on the outside of the limit bar. A limit block is fixedly disposed at one end of the limit bar.

[0010] One of the limiting discs has multiple limiting holes on its surface. The limiting rod is inserted into the limiting hole. The connecting post is connected to the first ruler body. One end of the limiting rod passes through the L-shaped fixing block and extends outward from the L-shaped fixing block. The other end of the limiting rod passes through the second ruler body and extends inward from the second ruler body. A handle is fixedly provided on one side of the cross slider.

[0011] By adopting the above technical solution, the angle adjustment is flexible, the first and second rulers can rotate relative to each other through the connecting column, adapting to different measurement scenarios, and can quickly unlock and lock, ensuring angle stability during measurement and improving overall stability and durability.

[0012] As a further description of the above technical solution: An adjustment mechanism is provided on one side of the first ruler body and the second ruler body. The adjustment mechanism includes mounting grooves respectively opened inside the first ruler body and the second ruler body. An extension ruler is slidably arranged inside the mounting groove. A stabilizing block is fixedly arranged at one end of the extension ruler.

[0013] The surfaces of the first and second rulers are both provided with auxiliary grooves. Inside the auxiliary grooves, there are slidable guide bars and finger lines. The guide bars are located on one side of the finger lines and are connected to the surface of the extension ruler.

[0014] By adopting the above technical solution, the length can be flexibly adjusted, the extension ruler can slide in the mounting groove to meet different measurement distance requirements, improve the applicability of the measuring ruler, and the indicator bar and the finger line are connected to the extension ruler and slide in the auxiliary groove, which makes it convenient to observe the position and extension length of the extension ruler, improve measurement accuracy and efficiency, and enhance the practicality and reliability of the measuring ruler in length adjustment.

[0015] As a further description of the above technical solution: the surfaces of the first ruler and the second ruler are each provided with a plurality of fixing slots, and a U-shaped fixing frame is inserted into the inside of the fixing slot. The surface of the extension ruler is provided with a slot, and a first magnetic absorbing piece is fixedly installed inside the slot. A second magnetic absorbing piece is fixedly installed at one end of the U-shaped fixing frame. The first magnetic absorbing piece and the second magnetic absorbing piece are magnetically connected.

[0016] The extension ruler, the first ruler body, and the second ruler body all have scale lines fixedly provided on their surfaces, and the extension ruler, the first ruler body, and the second ruler body are all made of aluminum alloy.

[0017] By adopting the above technical solution, it is convenient to read measurement data, improves the accuracy and efficiency of measurement, can adapt to the complex environment of building measurement, and is lightweight, easy to carry and use, thus enhancing the practicality and reliability of the measuring ruler.

[0018] The technical effects and advantages of this utility model are as follows:

[0019] By incorporating a locking mechanism, compared to existing technologies, the first and second rulers are connected via a connecting column and a limiting plate, allowing them to rotate relative to each other around the connecting column. This flexibly adapts to different measurement angle requirements, increasing the usability and applicability of the measuring ruler. Pulling the handle easily releases the lock, allowing the two rulers to rotate freely for convenient angle adjustment. The operation is simple and quick. Once the desired angle is reached, releasing the handle causes a spring to push the limiting rod into the limiting hole, achieving reliable locking and ensuring a fixed angle between the two rulers during measurement. This improves the accuracy and stability of the measurement. The overall structure is compact, with all components working closely together, ensuring both convenient angle adjustment and secure locking, thus enhancing the practicality and reliability of the measuring ruler.

[0020] By incorporating an adjustment mechanism, compared to existing technologies, the extension ruler can be easily fixed and unlocked via a magnetically connected U-shaped fixing frame and magnetic plate. Simply pull out the U-shaped fixing frame to extend the extension ruler, or insert it to secure it. The operation is simple and efficient. Furthermore, as the extension ruler slides, the indicator strip and the finger line slide within the auxiliary groove, facilitating observation of the position of the first magnetic plate and the extension length. This allows the measuring personnel to accurately control the extent to which the extension ruler is pulled out, improving measurement accuracy. Both the angle and length can be flexibly adjusted and reliably locked, meeting various measurement needs. It is also easy to carry, easily handling measurement scenarios in confined spaces or at different angles, greatly enhancing the convenience and practicality of measurement.

[0027] 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.

[0028] The embodiments disclosed in this application are as follows: Figure 1-5 The adjustable building measuring ruler shown includes a first ruler body 1, a connecting column 2 fixedly installed on one side of the first ruler body 1, a second ruler body 3 sleeved on the surface of the connecting column 2, limit plates 4 fixedly installed at both ends of the connecting column 2, and a locking mechanism installed on one side of the second ruler body 3.

[0029] The locking mechanism includes an L-shaped fixing block 5 fixedly installed on one side of the second ruler body 3. The L-shaped fixing block 5 has a groove 6 inside. A cross slider 7 is slidably installed inside the groove 6. A fixing plate 8 is fixedly installed at the bottom of the cross slider 7. A limit bar 9 is fixedly installed inside the fixing plate 8. A spring 10 is sleeved on the outside of the limit bar 9. A limit block 11 is fixedly installed at one end of the limit bar 9.

[0030] One of the limiting discs 4 has multiple limiting holes 12 on its surface. The limiting rod 9 is inserted into the limiting hole 12. The connecting post 2 is connected to the first ruler 1. One end of the limiting rod 9 passes through the L-shaped fixing block 5 and extends outward from the L-shaped fixing block 5. The other end of the limiting rod 9 passes through the second ruler 3 and extends inward from the second ruler 3. A handle 13 is fixedly provided on one side of the cross slider 7. The connecting post 2 is fixedly connected to one side of the first ruler 1. The second ruler 3 is sleeved on the outside of the connecting post 2. The limiting discs 4 at both ends of the connecting post 2 can prevent the second ruler 3 from falling off the connecting post 2. At this time, the first ruler 1 and the second ruler 3 are in a connected state. The limiting rod 9 in the locking mechanism is inserted into the limiting hole 12 on the surface of one of the limiting discs 4, so that the angle between the first ruler 1 and the second ruler 3 is locked.

[0031] When it is necessary to lock the first ruler 1 and the second ruler 3 for angle adjustment and locking, pull the handle 13. The handle 13 drives the cross slider 7 to slide in the groove 6 of the L-shaped fixing block 5. The cross slider 7 drives the fixing plate 8 to move. The fixing plate 8 causes the limit bar 9 to move along with it. At the same time, the spring 10 is compressed, and the limit bar 9 is pulled out from the limit hole 12 on the surface of one of the limit plates 4. At this time, the first ruler 1 and the second ruler 3 are unlocked and can rotate relative to each other around the connecting column 2 to rotate the first ruler 1 and the second ruler 3 to the required measurement angle.

[0032] When the second ruler 3 is rotated to the desired angle, the handle 13 is released, the compressed spring 10 recovers its elastic deformation, pushes the fixing plate 8 to move in the opposite direction, and the fixing plate 8 drives the limiting rod 9 to be inserted into the corresponding limiting hole 12, thereby locking the angle between the first ruler 1 and the second ruler 3.

[0033] Reference Figure 2-3 As shown, an adjustment mechanism is provided on one side of the first ruler 1 and the second ruler 3. The adjustment mechanism includes mounting grooves 14 respectively opened inside the first ruler 1 and the second ruler 3. An extension ruler 15 is slidably arranged inside the mounting groove 14. A stabilizing block 16 is fixedly arranged at one end of the extension ruler 15.

[0034] The surfaces of the first ruler 1 and the second ruler 3 are both provided with auxiliary grooves 17. Inside the auxiliary grooves 17, there are slidable guide bars 18 and guide lines 19. The guide bars 18 are located on one side of the guide lines 19 and are connected to the surface of the extension ruler 15.

[0035] When the second ruler 3 is rotated to the desired angle, the handle 13 is released, the compressed spring 10 recovers its elastic deformation, pushes the fixing plate 8 to move in the opposite direction, and the fixing plate 8 drives the limiting rod 9 to be inserted into the corresponding limiting hole 12, thereby locking the angle between the first ruler 1 and the second ruler 3.

[0036] Next, when the length of the first ruler 1 and the second ruler 3 needs to be adjusted, first pull the U-shaped fixing frame 21 out of the fixing slot 20. Since the magnetic connection between the first magnetic piece 22 and the second magnetic piece 23 is released, the extension ruler 15 is no longer fixed.

[0037] Then, hold the stabilizing block 16 of the extension ruler 15 and pull the extension ruler 15 out of the mounting slot 14. During the sliding process of the extension ruler 15, the pointing bar 18 and the pointing line 19 connected to the surface of the extension ruler 15 will slide in the auxiliary slot 17. The pointing bar 18 makes it easy to observe the position of the first magnetic piece 22 in the extension ruler 15, and the pointing line 19 makes it easy to observe the length of the extension.

[0038] Reference Figure 4-5 As shown, the surfaces of the first ruler 1 and the second ruler 3 are provided with multiple fixing slots 20. A U-shaped fixing frame 21 is inserted into the inside of the fixing slot 20. The surface of the extension ruler 15 is provided with a slot. A first magnetic piece 22 is fixedly installed inside the slot. A second magnetic piece 23 is fixedly installed at one end of the U-shaped fixing frame 21. The first magnetic piece 22 and the second magnetic piece 23 are magnetically connected.

[0039] The surfaces of the extension ruler 15, the first ruler body 1, and the second ruler body 3 are all fixedly provided with scale lines 24. The extension ruler 15, the first ruler body 1, and the second ruler body 3 are all made of aluminum alloy.

[0040] When the extension ruler 15 is pulled out to the appropriate length, the U-shaped fixing frame 21 is inserted into the corresponding fixing slot 20. At this time, the second magnetic piece 23 at one end of the U-shaped fixing frame 21 is magnetically connected to the first magnetic piece 22 in the slot of the extension ruler 15, fixing the extension ruler 15 in the current position.

[0041] After adjusting and locking the angle and length, the measuring ruler is used for building measurement. The surveyor can read the measurement data according to the scale lines 24 on the surface of the extension ruler 15, the first ruler body 1, and the second ruler body 3. Since they are all made of aluminum alloy, the measuring ruler has a certain strength and durability, which can meet the needs of building measurement, and is easy to carry and use for a long time.

[0042] Working principle of this utility model:

[0043] This utility model is a quick-locking adjustable building measuring ruler. When the device is in use, the first ruler body 1 is fixedly connected to the connecting column 2 on one side, and the second ruler body 3 is sleeved on the outside of the connecting column 2. The limiting plates 4 at both ends of the connecting column 2 can prevent the second ruler body 3 from falling off the connecting column 2. At this time, the first ruler body 1 and the second ruler body 3 are in a connected state. The limiting rod 9 in the locking mechanism is inserted into the limiting hole 12 on the surface of one of the limiting plates 4, so that the angle between the first ruler body 1 and the second ruler body 3 is locked.

[0044] When it is necessary to lock the first ruler 1 and the second ruler 3 for angle adjustment and locking, pull the handle 13. The handle 13 drives the cross slider 7 to slide in the groove 6 of the L-shaped fixing block 5. The cross slider 7 drives the fixing plate 8 to move. The fixing plate 8 causes the limit bar 9 to move along with it. At the same time, the spring 10 is compressed, and the limit bar 9 is pulled out from the limit hole 12 on the surface of one of the limit plates 4. At this time, the first ruler 1 and the second ruler 3 are unlocked and can rotate relative to each other around the connecting column 2 to rotate the first ruler 1 and the second ruler 3 to the required measurement angle.

[0045] When the second ruler 3 is rotated to the desired angle, the handle 13 is released, the compressed spring 10 recovers its elastic deformation, pushes the fixing plate 8 to move in the opposite direction, and the fixing plate 8 drives the limiting rod 9 to be inserted into the corresponding limiting hole 12, thereby locking the angle between the first ruler 1 and the second ruler 3.

[0046] Next, when the length of the first ruler 1 and the second ruler 3 needs to be adjusted, first pull the U-shaped fixing frame 21 out of the fixing slot 20. Since the magnetic connection between the first magnetic piece 22 and the second magnetic piece 23 is released, the extension ruler 15 is no longer fixed.

[0047] Then, hold the stabilizing block 16 of the extension ruler 15 and pull the extension ruler 15 out of the mounting slot 14. During the sliding process of the extension ruler 15, the pointing bar 18 and the pointing line 19 connected to the surface of the extension ruler 15 will slide in the auxiliary slot 17. The pointing bar 18 makes it easy to observe the position of the first magnetic piece 22 in the extension ruler 15, and the pointing line 19 makes it easy to observe the length of the extension.

[0048] When the extension ruler 15 is pulled out to the appropriate length, the U-shaped fixing frame 21 is inserted into the corresponding fixing slot 20. At this time, the second magnetic piece 23 at one end of the U-shaped fixing frame 21 is magnetically connected to the first magnetic piece 22 in the slot of the extension ruler 15, fixing the extension ruler 15 in the current position.

[0049] After adjusting and locking the angle and length, the measuring ruler is used for building measurement. The surveyor can read the measurement data according to the scale lines 24 on the surface of the extension ruler 15, the first ruler body 1, and the second ruler body 3. Since they are all made of aluminum alloy, the measuring ruler has a certain strength and durability, which can meet the needs of building measurement, and is easy to carry and use for a long time.

[0050] The above are all preferred embodiments of this application and are not intended to limit the scope of protection of this application. Therefore, all equivalent changes made in accordance with the structure, shape and principle of this application should be covered within the scope of protection of this application.
