Abstract
Description
Technical Field
[0001] This utility model relates to the field of measuring tool technology, specifically to a multifunctional measuring tool. Background Technology
[0002] In the construction and subsequent maintenance of pipelines in municipal engineering, water supply and drainage, petrochemical, and gas transmission, rapid and accurate measurement of pipeline burial depth, diameter, and internal silt thickness is a key step in project quality acceptance, pipeline condition assessment, and maintenance plan development.
[0003] Currently, field operators typically rely on the following independent tools and methods for step-by-step measurements: Measuring pipe burial depth: Manual measurement using a steel tape measure or ruler is commonly employed. This method requires one or more people to work together to pull the measuring instrument from the top of the pipe to the ground. Because it is difficult to keep the measuring instrument perfectly vertical, and factors such as uneven ground and obstructions above the pipe cause significant reading errors and low efficiency.
[0004] Measuring the outer diameter of pipes: Usually, a measuring tape is used to encircle the pipe wall or external clamps are used for positioning measurement. When the pipe is partially buried or located in a narrow manhole, the operating space is severely limited, the measuring tape cannot be encircled smoothly, and the clamps are difficult to keep stably attached to the pipe wall covered with mud, making the measurement process time-consuming and laborious, and the results unreliable.
[0005] Measuring the thickness of silt inside the tube: A common practice is to use a simple graduated rod or probe to vertically insert into the silt until it touches the bottom, then pull it out and estimate the silt thickness by observing the silt marks on the rod. This method is extremely inconvenient, requiring manual memorization or secondary calculation (e.g., total length minus clear water depth), and the rod is easily stained, causing the scale to become blurred and misread, making it difficult to guarantee measurement accuracy.
[0006] In summary, to complete the three basic measurements, on-site personnel need to carry three different tools and switch back and forth between them, making the operation process cumbersome and complex. This not only increases labor intensity and working time but also, due to the numerous tools and different reading methods, easily leads to operational errors and reading confusion. Furthermore, in construction and maintenance sites with limited space or harsh environments, frequent tool changes further reduce the convenience and safety of the work. Utility Model Content
[0007] The purpose of this invention is to provide a multifunctional measuring tool with a simple structure and convenient reading.
[0008] To achieve the above objectives, this utility model provides a multifunctional measuring tool, including a first movable member and a second movable member. The first movable member is provided with a first sliding engagement part, a first scale, and a first measuring jaw. The first sliding engagement part and the first scale are both arranged along the extension direction of the first movable member. The reading of the first scale gradually increases from the first end of the first movable member to its second end. The first measuring jaw is disposed on the second end of the first movable member. The second movable member is provided with a second sliding engagement part, a second scale, and a second measuring jaw. The second sliding engagement part is slidably connected to the first sliding engagement part. The second scale is arranged along the extension direction of the second movable member. The reading of the second scale gradually decreases from the first end of the second movable member to its second end. The second measuring jaw is disposed on the second end of the second movable member. The first measuring jaw and the second measuring jaw are arranged opposite each other and both extend towards the same side.
[0009] As can be seen from the above scheme, with the above settings, the multifunctional measuring tool of this utility model can be used to measure the burial depth, pipe diameter, and thickness of silt inside the pipe, and has good multifunctionality. By setting the reading of the first scale to gradually increase from the first end of the first movable part to its second end, when measuring the thickness of silt inside the pipe, the relevant reading is located at the top of the measuring tool, which is convenient for the staff to read the data. At the same time, the reading of the second scale is set to gradually decrease from the first end of the second movable part to its second end, so that the pipe burial depth data can be read simultaneously during the measurement of silt thickness, and all readings are located at the top of the measuring workpiece, which further improves the convenience of on-site operation and reading efficiency.
[0010] A further option is to designate one of the first sliding fit portion and the second sliding fit portion as a sliding groove and the other as a sliding protrusion, with the sliding groove and the sliding protrusion engaging in a concave-convex fit.
[0011] A further option is to design the sliding groove as a T-shaped groove, with a first flat plate on each side of the groove opening, and a first scale on the first flat plate.
[0012] A further option is that the second movable part is also provided with a second flat plate, which is located above the second sliding fit part, and a second scale is located on the second flat plate.
[0013] A further embodiment is that multiple protrusions are provided between the first movable member and the second movable member; the protrusions protrude from the surface of the first movable member and make point contact with the second movable member, or the protrusions protrude from the surface of the second movable member and make point contact with the first movable member.
[0014] A further option is that the extension length of the second measuring jaw is greater than or equal to the extension length of the first measuring jaw, and the side of the second measuring jaw facing the first measuring jaw is provided with an inclined surface.
[0015] A further option is to provide a detachable connection structure between the first and second measuring jaws, which includes a magnetic connection structure and / or a snap-fit structure.
[0016] A further embodiment is that the magnetic connection structure includes a first magnetic element and a second magnetic element. The first magnetic element is disposed on the side of the first measuring claw facing the second measuring claw, and the surface of the first magnetic element is flush with the surface of the first measuring claw. The second magnetic element is disposed on the side of the second measuring claw facing the first measuring claw and is correspondingly disposed to the first magnetic element. The surface of the second magnetic element is flush with the surface of the second measuring claw. Attached Figure Description

[0022] The present invention will be further described below with reference to the accompanying drawings and embodiments. Detailed Implementation
[0023] See Figures 1 to 4 The multifunctional measuring tool provided in this embodiment includes a first movable part 1 and a second movable part 2. The first movable part 1 and the second movable part 2 are connected and can slide relative to each other.
[0024] The first movable member 1 is provided with a first sliding fit, a first scale 12, and a first measuring jaw 13. Both the first sliding fit and the first scale 12 are arranged along the extending direction of the first movable member 1. The reading of the first scale 12 gradually increases from the first end of the first movable member 1 to its second end; that is, the zero point of the first scale 12 is located at the first end of the first movable member 1, and the first scale 12 can extend to the middle of the first movable member 1 or its second end. The first measuring jaw 13 is vertically arranged on the second end of the first movable member 1, extending away from the side where the first scale 12 is located. The width of the first measuring jaw 13 can be equal to or less than the width of the first movable member 1, and is not limited here.
[0025] The second movable member 2 is provided with a second sliding engagement portion, a second scale 22, and a second measuring jaw 23. Both the second sliding engagement portion and the second scale 22 are arranged along the extending direction of the second movable member 2. The second sliding engagement portion is slidably connected to the first sliding engagement portion. In this embodiment, the first end of the second movable member 2 corresponds to the first end of the first movable member 1, and the second end of the second movable member 2 corresponds to the second end of the first movable member 1. The reading of the second scale 22 gradually decreases from the first end to the second end of the second movable member 2, that is, the zero point of the second scale 22 is located at the second end of the second movable member 2. The second measuring jaw 23 is vertically arranged on the second end of the second movable member 2, extending away from the side where the second scale 22 is located, and the first measuring jaw 13 and the second measuring jaw 23 are arranged opposite each other and both extend towards the same side.
[0026] One of the first and second sliding mating parts is a sliding groove 11, and the other is a sliding protrusion 21, with the sliding groove 11 and the sliding protrusion 21 engaging in a concave-convex fit. In this embodiment, the first sliding mating part is the sliding groove 11, and the second sliding mating part is the sliding protrusion 21. Specifically: The sliding groove 11 is a T-shaped groove with an opening facing upwards. A first flat plate portion 14 is provided on each side of the opening of the sliding groove 11, and a first scale 12 is mounted on the first flat plate portion 14. The sliding protrusion 21 is a T-shaped structure, embedded within the sliding groove 11, with a portion of the sliding protrusion 21 protruding beyond the opening of the sliding groove 11.
[0027] The second movable part 2 is also provided with a second flat plate part 24, which is located above the sliding protrusion 21 and outside the sliding groove 11.
[0028] Grooves 25 are provided on both the left and right sides between the second flat plate portion 24 and the sliding protrusion 21, with the openings of the two grooves 25 facing away from each other. The two first flat plates 14 are respectively embedded in the corresponding grooves 25 and slide in cooperation with the grooves 25.
[0029] The second scale 22 is disposed on the second flat plate portion 24. Preferably, the first scale 12 and the second scale 22 are located on the left and right sides of the sliding groove 11, respectively.
[0030] exist Figure 3 In this embodiment, a plurality of protrusions are provided between the first movable member 1 and the second movable member 2. The protrusions protrude from the surface of the first movable member 1 and make point contact with the second movable member 2, or the protrusions protrude from the surface of the second movable member 2 and make point contact with the first movable member 1. In this embodiment, the former is preferred.
[0031] In this embodiment, the bottom of the sliding groove 11 is provided with at least two rows of first protrusions 15, and each row of first protrusions 15 is evenly spaced along the extending direction of the sliding groove 11. The first protrusions 15 protrude from the bottom of the sliding groove 11 and are used to make point contact with the bottom wall of the sliding protrusion 21 to reduce the contact area between the sliding protrusion 21 and the sliding groove 11, thereby reducing the friction between the two and making it easier for the operator to push the first movable part 1 and the second movable part 2 to move relative to each other.
[0032] Furthermore, each of the two first flat plate portions 14 is provided with a plurality of second protrusions 16, which are evenly spaced along the extending direction of the first flat plate portion 14. The second protrusions 16 protrude from the surface of the first flat plate portion 14 and are used to make point contact with the second flat plate portion 24, thereby further reducing the friction between the first movable member 1 and the second movable member 2.
[0033] exist Figure 1 and Figure 2 In the process, the length of the second measuring claw 23 is greater than or equal to the length of the first measuring claw 13, and the second measuring claw 23 is provided with an inclined surface on the side facing the first measuring claw 13, so that the second measuring claw 23 can be easily inserted into the silt 5 and pulled out of the silt 5.
[0034] To prevent relative movement between the first movable member 1 and the second movable member 2 when measurement is not required, this embodiment provides a detachable connection structure (not shown in the figure) between the first measuring jaw 13 and the second measuring jaw 23. The detachable connection structure includes a magnetic connection structure and / or a snap-fit structure.
[0035] The magnetic connection structure includes a first magnetic component and a second magnetic component. The first magnetic component is disposed on the side of the first measuring claw 13 facing the second measuring claw 23, and the surface of the first magnetic component is flush with the surface of the first measuring claw 13. The second magnetic component is disposed on the side of the second measuring claw 23 facing the first measuring claw 13 and is correspondingly disposed to the first magnetic component. The surface of the second magnetic component is flush with the surface of the second measuring claw 23.
[0036] One of the first and second magnetic components is a magnet, and the other is a metal component that can be magnetically attracted to the magnet. Alternatively, the first and second magnetic components can be two magnets with opposite magnetic poles.
[0037] See Figure 5 and combined Figure 2 The multi-functional measuring tool in this embodiment can be used to measure the burial depth of pipe 4, pipe diameter, and the thickness of silt 5 in pipe 4.
[0038] When it is necessary to measure the thickness of silt 5 in pipe 4, insert the second measuring jaw 23 into the bottom of silt 5, while controlling the first measuring jaw 13 to be just above the surface of silt 5. At this time, the reading on the first scale 12 is the thickness L1 of silt 5. Since the reading is located at the top of the multi-functional measuring tool, it is convenient for the operator to read the value.
[0039] Simultaneously, the reading at the position where the ground 3 is level with the second scale 22 is taken, which is the burial depth of pipe 4. The burial depth of pipe 4 is the vertical distance H1 from the bottom of the pipe to the ground 3. If the vertical distance H2 from the top of the pipe to the ground 3 is required, it can be calculated using the formula H2=H1-D, where D is the diameter of pipe 4.
[0040] When it is necessary to measure the diameter of pipe 4, place the first measuring jaw 13 and the second measuring jaw 23 on the top and bottom of the pipe respectively, and read the reading on the first scale 12 to obtain the diameter D of pipe 4.
[0041] In summary, through the above-mentioned design, this utility model's multifunctional measuring tool can be used to measure the burial depth, pipe diameter, and thickness of silt 5 inside the pipe, demonstrating excellent versatility. By setting the reading of the first scale 12 to gradually increase from the first end of the first movable part 1 to its second end, the relevant reading is located at the top of the measuring tool when measuring the thickness of the silt 5 inside the pipe, making it convenient for operators to read the data. Simultaneously, the reading of the second scale 22 is set to gradually decrease from the first end of the second movable part 2 to its second end, allowing the burial depth data of the pipe 4 to be read simultaneously during the measurement of silt thickness, and all readings are located at the top of the measuring workpiece, further improving the convenience of on-site operation and reading efficiency.
[0042] Finally, it should be emphasized that the above are only preferred embodiments of the present utility model and are not intended to limit the present utility model. For those skilled in the art, the present utility model can have various changes and modifications. 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.
