Description

Technical Field

[0001] This utility model relates to the field of construction tools and measurement technology, and in particular to a construction positioning ruler. Background Technology

[0002] Building construction includes not only civil buildings such as residential buildings and office buildings, but also infrastructure construction such as industrial plants, bridges, tunnels, and municipal roads. However, after the main structure of the building has passed the acceptance inspection, the focus of construction shifts to the decoration and finishing stage, that is, the tiling of the structural surface.

[0003] When tiling, workers use a hole-opening positioning ruler to measure and adapt to various hole-opening needs. This ruler typically has three to four sets of round holes for easy positioning. However, non-standard sized parts are sometimes encountered during tiling, such as water supply and drainage pipes whose diameter differs significantly from the positioning ruler's holes (e.g., a pipe diameter of 90mm, while the smallest hole on the ruler is 100mm). Workers must then choose the closest available hole for positioning, which directly leads to a deviation between the marked hole outline and the actual pipe diameter. This results in the final tile hole diameter being too large or too small. If the hole is too large, noticeable gaps will appear after pipe installation, requiring additional grout filling, increasing construction steps and potentially causing water leakage due to poor sealing. If the hole is too small, the pipe cannot pass through the tile smoothly, requiring repeated hole enlargement, which can easily cause tile edge cracking and damage, increasing material waste. Therefore, a new construction positioning ruler is proposed to solve these problems. Utility Model Content

[0004] To overcome the above shortcomings, this utility model provides a construction positioning ruler, which aims to improve the problem in the prior art that the single-diameter circular hole positioning ruler will affect the subsequent drilling diameter when encountering non-standard water supply and drainage pipes.

[0005] To achieve the above objectives, the present invention adopts the following technical solution: a construction positioning ruler, including an opening positioning ruler, wherein an adjustment mechanism is provided on the inner right side wall of the opening positioning ruler; The adjustment mechanism includes a fixed plate, a guide groove on the upper part of the fixed plate, a movable column slidably connected to the inner wall of the guide groove, a clamping piece fixedly connected to the upper part of the movable column, a contact column fixedly connected to the upper part of the clamping piece, a rotating plate rotatably connected to the upper inner wall of the fixed plate, a fixing component on the left side of the rotating plate, and a disassembly mechanism on the inner wall of the opening positioning ruler.

[0006] As a further description of the above technical solution: A circular hole is formed on the upper part of the rotating plate, and the inner diameter of the circular hole matches and contacts the diameter of the contact post.

[0007] As a further description of the above technical solution: Both the rotating plate and the fixed plate have through holes at their centers.

[0008] As a further description of the above technical solution: The fixing component includes a fixing block fixedly connected to the left side of the rotating plate. The inner wall of the fixing block is threaded with a threaded rod, and the bottom of the threaded rod is fixedly connected to a base plate. The bottom of the base plate is in contact with the upper part of the opening positioning ruler.

[0009] As a further description of the above technical solution: The clamping plates are provided in multiple sets, and the multiple sets of clamping plates are staggered.

[0010] As a further description of the above technical solution: The disassembly mechanism includes a rotating plate rotatably connected to the inner wall of the opening positioning ruler. The inner wall of the rotating plate is elastically connected to a limiting plate via a connecting spring. A connecting block is fixedly connected to the front of the fixing plate. A square groove is provided on the right side of the connecting block. The side of the limiting plate away from the connecting spring is inserted into the inside of the square groove.

[0011] As a further description of the above technical solution: The outer wall of the limiting plate is slidably connected to the inner wall of the rotating plate.

[0012] As a further description of the above technical solution: A baffle is fixedly connected to the side of the limiting plate facing the connecting spring.

[0013] This utility model has the following beneficial effects: 1. In this utility model, through the cooperation between the set opening positioning ruler and its adjustment mechanism, when the construction personnel rotate the rotating plate, its upper round hole drives the contact column to move, causing the movable column to slide along the guide groove. It can adapt to non-standard size accessories such as water supply and drainage pipe interfaces of different diameters, ensuring that the opening size matches the accessories, preventing the accessories from loosening later, and ensuring the sealing and stability of tile laying and accessory installation.

[0014] 2.

[0017] 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.

[0018] Reference Figures 1-3 The present invention provides an embodiment of a construction positioning ruler, including a hole positioning ruler 1. The hole positioning ruler 1 is made of high-strength aluminum alloy and the surface is anodized, which has wear-resistant and corrosion-resistant properties and can adapt to the complex environment of the construction site. An adjustment mechanism 2 is provided on the right inner wall of the hole positioning ruler 1. The adjustment mechanism 2 can be adjusted according to different hole sizes and position requirements during construction, which greatly improves the versatility of the positioning ruler.

[0019] Reference Figures 2-4The adjusting mechanism 2 includes a fixed plate 202, the shape of which matches the inner wall of the opening positioning ruler 1 to ensure that it will not shake after installation. A guide groove 205 is provided on the upper part of the fixed plate 202. A movable column 207 is slidably connected to the inner wall of the guide groove 205. Multiple sets of guide grooves 205 are provided and are opened along the length of the fixed plate 202. The inner wall is polished and smooth, providing a smooth track for the sliding of the movable column 207 and ensuring the stability of the movable column 207 when it moves. The movable column 207 adopts a cylindrical design, and its outer wall fits against the inner wall of the guide groove 205, so that no large gap is generated when sliding. A clamping piece 204 is fixedly connected to the upper part of the movable column 207. The clamping piece 204 is made of elastic metal sheet and has a certain toughness.

[0020] Furthermore, a contact post 206 is fixedly connected to the upper part of the clamping piece 204, and a rotating plate 201 is rotatably connected to the upper inner wall of the fixing plate 202. The contact post 206 is made of hard plastic. The rotation of the rotating plate 201 drives the contact post 206 to move, thereby realizing the position adjustment of the clamping piece 204. The rotating plate 201 rotates flexibly and can change the position of the contact post 206 by rotation, thereby adjusting the spacing of the clamping pieces 204. The operation is simple and convenient. A fixing component 203 is provided on the left side of the rotating plate 201. The fixing component 203 can fix the rotating plate 201 in the required position to prevent the rotating plate 201 from rotating on its own during the positioning process, which would cause the positioning size deviation and ensure the positioning accuracy. A disassembly mechanism 3 is provided on the inner wall of the opening positioning ruler 1. The disassembly mechanism 3 makes it easy to remove the adjustment mechanism 2 from the opening positioning ruler 1, which is convenient for individual maintenance or replacement of the adjustment mechanism 2.

[0021] Reference Figures 2-4 A circular hole is provided on the upper part of the rotating plate 201. The inner diameter of the circular hole matches and contacts the diameter of the contact post 206. The edge of the circular hole on the upper part of the rotating plate 201 is chamfered to avoid scratching the surface of the contact post 206 when it moves. The matching of the inner diameter of the circular hole with the diameter of the contact post 206 ensures that the contact post 206 can move smoothly with the rotation of the rotating plate 201 without jamming or loosening. Through holes are provided at the center of both the rotating plate 201 and the fixed plate 202. The through holes facilitate the measurement of the corresponding water supply and drainage pipe interface on the wall, which facilitates the subsequent drilling of tiles.

[0022] Reference Figures 2-4The fixing component 203 includes a fixing block 2031 fixedly connected to the left side of the rotating plate 201. A threaded rod 2032 is threadedly connected to the inner wall of the fixing block 2031. The fixing block 2031 is welded and fixed to the left side of the rotating plate 201. It is made of high-strength steel and can withstand the tightening force of the threaded rod 2032, ensuring the structural stability of the fixing component 203. The inner wall of the fixing block 2031 is provided with precision threads, which fit tightly with the threaded rod 2032 to prevent stripping. A base plate 2033 is fixedly connected to the bottom of the threaded rod 2032. The bottom of the base plate 2033 contacts the upper part of the opening positioning ruler 1. The top of the threaded rod 2032 is... Equipped with a knob featuring anti-slip texture, it facilitates manual adjustment by construction personnel, saving time and effort. The base plate 2033 is made of rubber with a rough bottom surface, generating significant friction when in contact with the upper part of the opening positioning ruler 1, thus firmly fixing the rotating plate 201 and preventing its rotation. Simultaneously, the rubber material prevents hard collisions between the base plate 2033 and the opening positioning ruler 1, protecting the surface of the ruler 1. Multiple sets of clamping plates 204 are provided, staggered in arrangement. This staggered arrangement allows for compatibility with water supply and drainage pipes of different diameters, improving the stability and accuracy of positioning.

[0023] Reference Figure 2 and Figure 5 The disassembly mechanism 3 includes a rotating plate 302 rotatably connected to the inner wall of the opening positioning ruler 1. The rotating plate 302 is rotatably connected to the inner wall of the opening positioning ruler 1 via a pin. The rotation angle is moderate, which facilitates the operation of the limiting plate 304 by construction personnel. The inner wall of the rotating plate 302 is elastically connected to the limiting plate 304 via a connecting spring 303. A connecting block 301 is fixedly connected to the front of the fixing plate 202. A square groove is opened on the right side of the connecting block 301. The side of the limiting plate 304 away from the connecting spring 303 is inserted into the square groove. The connecting spring 303 is a compression spring with a moderate elastic coefficient. In its natural state, it pushes the limiting plate 304 into the square groove, thereby fixing the connecting block 301 and the rotating plate 302. Meanwhile, the side of the limiting plate 304 away from the connecting spring 303 is square, matching the shape of the square groove on the right side of the connecting block 301, ensuring that it will not rotate after insertion. When disassembly is required, simply pull the limiting plate 304 against the spring force, which is convenient to operate. The outer wall of the limiting plate 304 is slidably connected to the inner wall of the rotating plate 302. The through-hole setting makes it easy to manually release the limiting plate 304. A baffle 305 is fixedly connected to the side of the limiting plate 304 facing the connecting spring 303. The baffle 305 is integrally formed with the limiting plate 304, providing a force point for pulling the limiting plate 304, and preventing dust from entering the interior of the rotating plate 302 when the connecting spring 303 is in the reset state.

[0024] Working principle: Before drilling and positioning, the clamping distance needs to be adjusted according to the size of the water supply and drainage pipe interface. The construction personnel rotate the rotating plate 201 on the upper part of the fixed plate 202 in the adjustment mechanism 2. The circular hole on the upper part of the rotating plate 201 drives the contact column 206 to move. The contact column 206 pushes the clamping plate 204 fixed at the lower part to move synchronously. Since the multiple sets of clamping plates 204 are staggered and the movable column 207 slides along the guide groove 205 on the upper part of the fixed plate 202, it ensures that the clamping plates 204 move smoothly until the multiple sets of clamping plates 204 move smoothly. 4. The spacing is adapted to the pipe interface size to meet the positioning requirements of tile opening. After adjustment, the position of the rotating plate 201 is locked by the fixing component 203. The threaded rod 2032 on the inner wall of the fixing block 2031 on the left side of the rotating plate 201 is rotated. The threaded rod 2032 drives the bottom rubber base plate 2033 to move downward until the base plate 2033 contacts the upper part of the opening positioning ruler 1, which firmly fixes the rotating plate 201 and prevents the rotating plate 201 from rotating on its own during the positioning process, thus ensuring the positioning accuracy of the opening. During positioning, the hole positioning ruler 1 is attached to the construction wall so that the through hole in the center of the fixed plate 202 and the rotating plate 201 is aligned with the water supply and drainage pipe interface. The clamping piece 204 is used to assist in positioning and mark the outline of the tile hole. Then, the subsequent hole-making work can be carried out. When it is necessary to maintain or replace the adjustment mechanism 2, the construction personnel pull the baffle 305 on one side of the limit plate 304 inside the rotating plate 302 to overcome the elastic force of the connecting spring 303, so that the limit plate 304 is disengaged from the square groove on the right side of the connecting block 301, and the fixing of the connecting block 301 is released. Then, the rotating plate 302 is rotated upward to a vertical position. Then, the adjustment mechanism 2 can be removed from the inner wall of the hole positioning ruler 1 for maintenance or replacement.

[0025] Finally, it should be noted that the above description is only a preferred embodiment of the present utility model and is not intended to limit the present utility model. Although the present utility model has been described in detail with reference to the foregoing embodiments, those skilled in the art can still modify the technical solutions described in the foregoing embodiments or make equivalent substitutions for some of the technical features. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of the present utility model should be included within the protection scope of the present utility model.
