DETAILED DESCRIPTION

[0035] The embodiments of the present invention are described in detail below, and examples of the embodiments are shown in the accompanying drawings, wherein the same or similar reference numerals throughout represent the same or similar elements or elements having the same or similar functions. The embodiments described below with reference to the accompanying drawings are exemplary and are only used to explain the present invention, and cannot be understood as limiting the present invention.

[0036] It should be noted that when an element is referred to as being "fixed to" another element, it may be directly on the other element or there may be a central element. When an element is considered to be "connected to" another element, it may be directly connected to the other element or there may be a central element at the same time. In contrast, when an element is referred to as being "directly on" another element, there is no intermediate element. The terms "vertical", "horizontal", "left", "right" and similar expressions used herein are for illustrative purposes only.

[0037] In the present invention, unless otherwise clearly specified and limited, the terms "install", "connect", "connect", "fix" and the like should be understood in a broad sense, 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 an indirect connection through an intermediate medium, it can be the internal connection of two elements or the interaction relationship between two elements. For ordinary technicians in this field, the specific meanings of the above terms in the present invention can be understood according to specific circumstances.

[0038] In addition, the terms "first" and "second" are used for descriptive purposes only and should not be understood as indicating or implying relative importance or implicitly indicating the number of the indicated technical features. Therefore, the features defined as "first" and "second" may explicitly or implicitly include one or more of the features. In the description of the present utility model, the meaning of "plurality" is two or more, unless otherwise clearly and specifically defined.

[0039] Unless otherwise defined, all technical and scientific terms used herein have the same meaning as those commonly understood by those skilled in the art to which this application belongs. The terms used in the specification of the template herein are only for the purpose of describing specific embodiments and are not intended to limit the present invention. The term "and / or" used herein includes any and all combinations of one or more of the related listed items.

[0040] like Figure 1 and Figure 2 As shown, some embodiments of the utility model provide a measuring device, which is mainly used for measuring various parameters of asphalt concrete, geotechnical materials and concrete in road pavements, geotechnical engineering and concrete structures, so as to improve the measurement efficiency and accuracy.

[0041] The measuring device includes a first leveler 100 , a second leveler 200 , and a measurer 300 .

[0042] There are at least one first leveler 100 and at least one second leveler 200, respectively. It is understandable that the number of the first leveler 100 and the second leveler 200 can be one, two, or more than two, and can be set according to actual conditions. In addition, the number of the first leveler 100 and the second leveler 200 can be equal or different.

[0043] It should be noted that, in the present embodiment, the level tube of the level is made of glass, the inner wall of the level tube is a curved surface with a certain radius of curvature, and liquid is contained in the tube. When the level is tilted, the bubble in the level tube moves toward the end of the level that is raised, thereby determining the position of the horizontal plane. The larger the radius of curvature of the inner wall of the level tube, the higher the resolution, and the smaller the radius of curvature, the lower the resolution. Therefore, the radius of curvature of the level tube determines the accuracy of the level. The level is mainly used to check the flatness, straightness, verticality of various machine tools and workpieces, and the horizontal position of equipment installation. In particular, when measuring verticality, the magnetic level can be adsorbed on the vertical working surface without manual support, which reduces the labor intensity and avoids the measurement error of the level caused by human body heat radiation.

[0044] The first leveler 100 includes a first connecting rod 110 and a first level 120. The side wall of the first connecting rod 110 is provided with a first notch, and the first level 120 is arranged in the first notch. Along the axis direction of the first connecting rod 110, one end of the first level 120 is connected to one side wall of the first notch, and the other end of the first level 120 is connected to the other side wall of the first notch. In this embodiment, the connection method between the first level 120 and the first connecting rod 110 includes any one of bonding, clamping, and threaded connection to improve the stability of the connection between the first level 120 and the first connecting rod 110.

[0045] By providing the first notch on the first connecting rod 110 , when the first level 120 is arranged in the first notch, the user can clearly see the first level 120 through the first notch, thereby determining whether the first connecting rod 110 is in a horizontal state.

[0046] In addition, the second leveler 200 includes a second connecting rod 210 and a second level 220. The side wall of the second connecting rod 210 is provided with a second notch, and the second level 220 is arranged in the second notch. Along the axis direction of the second connecting rod 210, one end of the second level 220 is connected to one side wall of the second notch, and the other end of the second level 220 is connected to the other side wall of the second notch. In this embodiment, the connection method between the second level 220 and the second connecting rod 210 includes any one of bonding, clamping, and threaded connection to improve the stability of the connection between the second level 220 and the second connecting rod 210.

[0047] By providing the second notch on the second connecting rod 210 , when the second level 220 is arranged in the second notch, the user can clearly see the second level 220 through the second notch, thereby judging whether the second connecting rod 210 is in a horizontal state.

[0048] In this embodiment, the number of the measuring devices 300 is at least one, that is, the number of the measuring devices 300 can be one, two, or any number above two, which can be specifically set according to actual conditions.

[0049] Along the first direction, at least one of the two opposite sides of the measuring device 300 is provided with a first mounting hole 310, and one end of the first leveler 100 is rotatably connected to the hole wall of the first mounting hole 310. It should be noted that during the rotation of the first leveler 100 relative to the measuring device 300, the rotation direction of the first leveler 100 is perpendicular to the axis of the first leveler 100, so that during use, the user can rotate the first leveler 100 so that the first level 120 in the first leveler 100 rotates to the coverage range of the user's line of sight, so that the user can adjust the first leveler 100 at different angles, so as to improve the convenience of adjusting the first leveler 100 and enhance the user's use experience.

[0050] Specifically, in this embodiment, the first connecting rod 110 is rotatably connected to the hole wall of the first mounting hole 310 .

[0051] Along the second direction, at least one of the two opposite sides of the measuring device 300 is provided with a second mounting hole 320, and one end of the second leveler 200 is rotatably connected to the hole wall of the second mounting hole 320. It should be noted that during the rotation of the second leveler 200 relative to the measuring device 300, the rotation direction of the second leveler 200 is perpendicular to the axis of the second leveler 200, so that during use, the user can rotate the second leveler 200 so that the second leveler 220 in the second leveler 200 rotates to the coverage range of the user's line of sight, so that the user can adjust the second leveler 200 at different angles, so as to improve the convenience of adjusting the second leveler 200 and enhance the user's use experience.

[0052] Specifically, in this embodiment, the second connecting rod 210 is rotatably connected to the hole wall of the second mounting hole 320 .

[0053] It should be noted that, in this embodiment, the measuring device 300 is used to selectively collect displacement, stress and temperature data according to different working conditions of the carrier.

[0054] The first direction is perpendicular to the second direction.

[0055] It can be understood that by connecting the first level 100 and the second level 200 to the measuring device 300 respectively, the measuring device 300 can be adjusted to be in a horizontal state to ensure the accuracy of the measuring device 300 in the process of measuring the carrier, and by rotatably connecting the first level 100 and the second level 200 to the measuring device 300 respectively, the user can rotate the first level 100 and the second level 200 according to his own position during use, so that the horizontal measuring parts of the first level 100 and the second level 200 are directly opposite to the effective line of sight of the user, so as to improve the flexibility of the measuring device during use. The measuring device 300 can selectively collect displacement, stress and temperature data according to different working conditions of the carrier, thereby improving the versatility of the measuring device in measuring the carrier.

[0056] like Figure 2 As shown, in some embodiments of the present invention, along the first direction, first mounting holes 310 are provided on two opposite sides of the measuring device 300 , the apertures of the two first mounting holes 310 are equal, and the axes of the two first mounting holes 310 coincide.

[0057] Along the second direction, two opposite sides of the measuring device 300 are each provided with a second mounting hole 320 , the apertures of the two second mounting holes 320 are equal, and the axes of the two second mounting holes 320 coincide with each other.

[0058] In addition, in some embodiments, the two first mounting holes 310 are connected to penetrate the measuring device 300 along the first direction, and the two second mounting holes 320 are connected to penetrate the measuring device 300 along the second direction.

[0059] like Figure 1 As shown, in some embodiments of the present invention, the number of the first leveler 100, the second leveler 200 and the measuring device 300 is multiple, and multiple first levelers 100, the second levelers 200 and the measuring devices 300 are connected to form the measuring device of a grid structure.

[0060] Specifically, each measuring device is connected to at least one first level 120 and at least one second level 220. By setting up a grid-structured measuring device, each first level 120 and second level 220 can be adjusted to be in a horizontal state, so as to further improve the accuracy of the measuring device during the detection process.

[0061] like Figure 2 As shown, in some embodiments of the present invention, the measuring device 300 includes a shell 330, a displacement measuring element 340, a temperature measuring element 350 and a stress measuring element 360, so as to measure the displacement of the carrier through the displacement measuring element 340, measure the current ambient temperature through the temperature measuring element 350, and measure the stress data of the carrier through the stress measuring element 360.

[0062] Among them, the displacement measuring element 340, the temperature measuring element 350 and the stress measuring element 360 are arranged at intervals on the outer wall of the shell 330, and the displacement measuring element 340, the temperature measuring element 350 and the stress measuring element 360 are respectively spaced from the first mounting hole 310, and the displacement measuring element 340, the temperature measuring element 350 and the stress measuring element 360 are respectively spaced from the second mounting hole 320 to ensure the stability of the connection between the first leveler 100 and the second leveler 200 and the measuring device 300 respectively.

[0063] like Figure 2 As shown, in some embodiments of the present invention, along the third direction, a connecting hole 331 is provided on one side of the shell 330 , and a connecting rib 400 is provided on one side of the shell 330 , and the connecting rib 400 is movably connected to the hole wall of the connecting hole 331 .

[0064] Specifically, the connection method between the connection rib 400 and the hole wall of the connection hole 331 includes any one of a sliding connection, a threaded connection, and abutment.

[0065] In this embodiment, the hole wall of the connecting hole 331 is provided with a first thread, and the outer wall of the connecting rib 400 is provided with a second thread. The first thread is connected to the second thread to thread the connecting rib 400 with the hole wall of the connecting hole 331, so that the relative position between the connecting rib 400 and the shell 330 can be adjusted by rotating the connecting rib 400.

[0066] It can be understood that by threading the connecting rib 400 and the shell 330, not only the stability of the connection between the connecting rib 400 and the shell 330 can be improved, but also the relative position between the connecting rib 400 and the shell 330 can be easily adjusted to improve the accuracy of the measuring device in measuring the corresponding parameters of the carrier.

[0067] It should be noted that the first direction and the second direction are both perpendicular to the third direction.

[0068] like Figure 1 and Figure 2 As shown, in some embodiments of the present invention, the connecting hole 331 passes through the shell 330 so that the connecting rib 400 can pass through the shell 330 during rotation, so as to further increase the adjustment range of the connecting rib 400 relative to the shell 330, so as to adapt to the measurement of different carriers and improve the measurement range of the measuring device.

[0069] like Figure 2 As shown, in some embodiments of the utility model, the first mounting hole 310 is an annular hole, and annular protrusions are respectively provided at both ends of the first leveler 100, and the annular protrusions are accommodated in the annular holes, so as to limit the annular protrusions along the axial direction of the first connecting rod 110 through the annular holes, so as to avoid the annular protrusions from detaching from the annular holes, thereby ensuring the stability of the connection between the first connecting rod 110 and the shell 330, thereby ensuring the stability of the connection between the first leveler 100 and the measuring device 300.

[0070] Specifically, the outer wall of the annular protrusion contacts the inner wall of the annular hole, so that there is friction between the inner wall of the annular hole and the annular protrusion, thereby preventing the first leveler 100 from shaking in the first notch, thereby improving the stability of the relative position of the first leveler 100 with respect to the first connecting rod 110 after rotation when the user rotates the first leveler 100.

[0071] like Figure 2As shown, in some embodiments of the utility model, the second mounting hole 320 is an annular hole, and annular protrusions are respectively provided at both ends of the second leveler 200, and the annular protrusions are accommodated in the annular holes to limit the annular protrusions along the axial direction of the second connecting rod 210 through the annular holes to avoid the annular protrusions from detaching from the annular holes, thereby ensuring the stability of the connection between the second connecting rod 210 and the shell 330, thereby ensuring the stability of the connection between the second leveler 200 and the measuring device 300.

[0072] Specifically, the outer wall of the annular protrusion contacts the inner wall of the annular hole so that there is friction between the inner wall of the annular hole and the annular protrusion, thereby preventing the second leveler 200 from shaking in the second notch, thereby improving the stability of the relative position of the second leveler 200 relative to the second connecting rod 210 after rotation when the user rotates the second leveler 200.

[0073] In some embodiments of the present invention, a first protective layer is disposed on the surface of the first leveler 100. In addition, a second protective layer is disposed on the surface of the second leveler 200.

[0074] In the present embodiment, the first protective layer and the second protective layer are both phenolic resin layers. It should be noted that phenolic resin has a benzene ring structure, so it is dimensionally stable and has a rate of change of less than 1%. It also has stable chemical composition, is corrosion-resistant and anti-aging, and is particularly resistant to corrosion by organic solutions, strong acids, and weak bases. In the production process, Freon is not used as a foaming agent, which complies with international environmental protection standards, and its molecular structure contains hydrogen, oxygen, and carbon elements. When decomposed at high temperature, the gas overflowed is non-toxic and odorless, and is harmless to the human body and the environment, which complies with national green environmental protection requirements. Therefore, phenolic super composite board is the most ideal fireproof, heat-insulating, energy-saving, and beautiful environmentally friendly green thermal insulation material.

[0075] It is understandable that by providing a phenolic resin layer on the surface of the first leveler 100 and the second leveler 200 , the first leveler 100 and the second leveler 200 are protected, thereby increasing the service life of the first leveler 100 and the second leveler 200 .

[0076] In all examples shown and described herein, any specific values ​​should be interpreted as merely exemplary and not as limiting, and thus other examples of the exemplary embodiments may have different values.

[0077] It should be noted that similar reference numerals and letters denote similar items in the following drawings, and therefore, once an item is defined in one drawing, further definition and explanation thereof is not required in subsequent drawings.

[0078] The above-mentioned embodiments only express several implementation methods of the present invention, and the description is relatively specific and detailed, but it cannot be understood as limiting the scope of the present invention. It should be pointed out that for ordinary technicians in this field, several modifications and improvements can be made without departing from the concept of the present invention, which all belong to the protection scope of the present invention.
