Description

Technical Field

[0001] This utility model relates to the field of measuring tool technology, and in particular to an engineering quality inspection ruler. Background Technology

[0002] Construction quality inspection rulers are measuring tools mainly used for construction and completion quality inspection of engineering projects such as building construction, decoration and renovation, bridge construction, and equipment installation. They mainly include vertical inspection rulers, diagonal inspection rulers, inner and outer right-angle inspection rulers, and vernier feeler gauges.

[0003] A utility model patent with publication number CN 213748199 U and publication date of July 20, 2021, discloses a quality inspection ruler for construction engineering, including a main ruler. The top of the main ruler is fixedly connected to two symmetrically arranged support blocks, and a rotating shaft is rotatably connected between the two support blocks. A clamping mechanism is provided on the rotating shaft. The main ruler has a first scale, and the clamping mechanism has a magnifying glass that cooperates with the first scale. An angle measuring mechanism is connected to the main ruler.

[0004] This utility model has a simple structure and is easy to use. When measuring wall thickness, the ruler can be fully fitted to the outer walls on both sides of the wall, improving the accuracy of the measurement. At the same time, it can meet the needs of staff with poor eyesight.

[0005] However, all such measuring rulers have the same problem: when quality inspectors are inspecting a house, especially when measuring the flatness of the walls, if there is a dent in the wall, they first place a rigid ruler tightly against the wall. At this time, a gap will appear between the wall and the ruler. In order to determine whether the size of this gap is within the range specified by the standard, the quality inspector needs to insert a feeler gauge into the gap for measurement and then judge based on the value of the feeler gauge. However, this inspection method is very cumbersome, requires the cooperation of two people, and requires the use of multiple measuring tools.

[0006] Therefore, there is an urgent need for an engineering quality inspection ruler to simplify the process of measuring wall dents and facilitate measurement. Utility Model Content

[0007] To address the aforementioned technical problems, this utility model provides an engineering quality inspection ruler, which solves the problem that existing inspection rulers require the use of both a ruler and a feeler gauge to measure wall recesses, resulting in a cumbersome and inconvenient measurement process.

[0008] The above-mentioned technical objective of this utility model is achieved through the following technical solution:

[0009] An engineering quality inspection ruler includes a body, on which at least one through hole is equally spaced, and a guide block is slidably provided on one side of the body. A guide hole is provided on the guide block along the axial direction of the through hole, and a ruler rod is provided in the guide hole. The ruler rod is etched with a scale for measuring the depth of wall recesses.

[0010] The guide block has threaded holes on both sides at positions perpendicular to the axis of the guide hole, and fixing bolts are installed in the threaded holes.

[0011] Furthermore, the main body is provided with a slide rail on one side of the guide block, and a T-shaped slide groove is formed on the slide rail along the length direction.

[0012] Furthermore, a T-shaped locking block is provided at one end of the guide block corresponding to the T-shaped groove.

[0013] Furthermore, the length of the ruler rod is greater than the width of the body.

[0014] Furthermore, the slide rail is provided with reference lines on both sides of the through hole, and the width of the reference lines is equal to that of the guide block.

[0015] Furthermore, the body is provided with at least one lighting mechanism.

[0016] Furthermore, the lighting mechanism includes a bracket, on which a mounting frame is rotatably mounted, and within the mounting frame, an LED light is rotatably mounted.

[0017] In summary, the beneficial technical effects of this utility model are as follows:

[0018] (1) Using a ruler instead of a feeler gauge, the guide block is slid to the position of the depression to be measured by the slide rail during measurement, so that the guide hole and the through hole are in the same position. The ruler is pushed along the guide hole to the lowest point of the depression. At this time, the depth of the depression can be quickly read on the ruler by using the body as the measurement reference. No feeler gauge is needed in this process, and only one worker is needed to complete it, which greatly simplifies the measurement process and improves the measurement efficiency.

[0019] (2) By using the fixing bolt, the position of the current ruler can be fixed after the measurement is completed, preventing the movement of the ruler from causing numerical errors.

[0020] (3) LED lights can illuminate the environment during measurement, making it easy to quickly position the guide block to the position to be measured and to read the value. Attached Figure Description

[0028] The present invention will now be described clearly and completely with reference to the embodiments.

[0029] It should be noted that all directional indicators (such as up, down, left, right, front, back, etc.) in this utility model embodiment are only used to explain the relative positional relationship and movement of each component in a certain specific posture (as shown in the figure). If the specific posture changes, the directional indicator will also change accordingly.

[0030] In the description of the embodiments, unless otherwise expressly specified and limited, the terms "set," "connect," etc., should be interpreted broadly. For example, it can be a fixed connection, a detachable connection, or an integral connection; it can be a mechanical connection or an electrical connection; it can be a direct connection or a connection through an intermediate medium, or it can be a connection within two components. Those skilled in the art can understand the specific meaning of the above terms in this utility model based on the specific circumstances.

[0031] See appendix Figures 1-5 The figure shows an engineering quality inspection ruler, including a body 1. A slide rail 3 is fixedly provided on one side of the body 1 along the length direction. A T-shaped slide groove 4 is provided on the slide rail 3 along the length direction. A through hole 2 is provided through the body 1 in the T-shaped slide groove 4. A guide block 5 is slidably provided in the T-shaped slide groove 4. A T-shaped locking block 6 is provided at one end of the guide block 5 corresponding to the T-shaped slide groove 4.

[0032] A guide hole is provided on the guide block 5 along the axial direction of the through hole 2. The diameter of the guide hole is equal to that of the through hole 2. A ruler 7 is inserted through the guide hole and extends to the through hole 2. The length of the ruler 7 is greater than the width of the body 1. This ensures that the ruler 7 can pass through the body 1 and has sufficient length to measure the depth of the recess 17. The ruler 7 is etched with a scale 8 for measuring the depth of the recess 17 in the wall 16. During measurement, one side of the body 1 is placed close to the wall 16. When the wall 16 has a recess 17, a gap will appear between the body 1 and the wall 16. At this time, the operator pushes the ruler 7 along the guide hole towards the bottom of the recess 17. When the end of the ruler 7 touches the bottom of the recess 17, the pushing is stopped. At this time, the depth of the recess 17 can be read intuitively by the length of the extended ruler 7 and the corresponding scale 8. In this measurement process, the ruler 7 replaces the feeler gauge, which simplifies the process of measuring the recess 17, facilitates the measurement, and improves the measurement efficiency.

[0033] In addition, to prevent the ruler 7 from moving during reading and causing reading errors, threaded holes are provided on both sides of the guide block 5 in a direction perpendicular to the axis of the guide hole. Each threaded hole is equipped with a fixing bolt 9. When the ruler 7 is pushed to the bottom of the recess 17, the fixing bolt 9 is used to fix the current position of the ruler 7 before reading.

[0034] Furthermore, in order to ensure that the ruler 7 can be smoothly inserted into the through hole 2, a reference line 11 is provided on both sides of each through hole 2. The width between the reference lines 11 is equal to the width of the guide block 5. Therefore, when the guide block 5 moves along the slide rail 3, when the two sides of the guide block 5 are exactly aligned with the reference line 11, the guide hole and the through hole 2 are concentric, and the ruler 7 can smoothly enter the through hole 2.

[0035] Furthermore, in order to facilitate the control of the ruler 7, a handle 10 for applying force is provided at one end of the ruler 7;

[0036] Finally, to enhance the functionality of the entire measuring ruler, multiple lighting mechanisms 12 are provided on the main body 1. When the operator is measuring, the lighting mechanisms 12 can illuminate the measuring environment, making it easier to accurately slide the guide block 5 to the measuring position. The lighting mechanism 12 includes a bracket 13 mounted on the main body 1. A mounting bracket 14 is rotatably mounted on the top of the bracket 13, and an LED light 15 is rotatably connected to the mounting bracket 14. Therefore, during measurement, the angle of the LED light 15 in various directions can be changed by rotating the bracket 13 and the mounting bracket 14, which facilitates measurement.

[0037] For usage, please refer to the appendix. Figure 6As shown, first, place the main body 1 against the wall 16 to be measured. If the wall 16 is flat, the main body 1 will be close to the wall 16 without gaps. When a local depression 17 appears on the wall 16, a large gap will appear between the wall 16 and the main body 1. At this time, the operator can push the ruler 7 forward along the through hole 2 through the handle 10 until the end of the ruler 7 touches the bottom of the depression 17. Then, fix the current position of the ruler 7 with the fixing bolt 9. Then, the depth of the depression 17 can be read with the side wall of the main body 1 as a reference.

[0038] The above description is only a preferred embodiment of the present utility model and is not intended to limit the scope of protection of the present utility model. Therefore, all equivalent changes made to the structure, shape and principle of the present utility model should be included within the scope of protection of the present utility model.
