Description
Technical Field
[0001] The invention relates to the field of measuring instruments, in particular to a multi-purpose measurement and detection work platform. Background Art
[0002] Measure detection is the process of obtaining a certain result by performing a series of repeated tests on the corresponding parameters of the measured object. In physics, it is usually a process performed on a tool through measuring instruments to obtain the correct result.
[0003] The measuring tools in the application fields of metrology and testing include: vernier calipers, inside and outside micrometers, dial indicators, micrometers, large-size measuring tools, length and angle block gauges: altimeters, length measuring instruments, levels, inclinometers, projectors, inductance meters, roughness meters, profile scanners, three-dimensional coordinate measuring machines, tool microscopes, mechanical metrology, mass metrology, force metrology, hardness metrology, capacity and density metrology, speed and vibration metrology, thermal metrology, temperature metrology, pressure metrology, flow and level (liquid level) metrology, software, and various metrology and management software.
[0004] When measuring the volume and density of an object, the more commonly used measurement method is the water displacement method. However, the common measuring devices and work platforms for measuring the volume and density of an object are not suitable for measuring objects with a density less than that of water. For objects that float on the water surface with a density less than that of water, acupressure, binding or hanging methods are usually used separately. Devices suitable for such methods can solve the problem of the object to be measured floating on the water surface, but no matter how small the volume of the structure used to fix the object is, it still has its own volume, which affects the accurate value of the actual test result. Summary of the invention
[0005] Based on this, the purpose of the present invention is to provide a multi-purpose measurement and detection work platform to solve the technical problem that it is difficult for existing measurement and detection devices or work platforms to measure objects to be measured with a density less than that of water and to obtain accurate values.
[0006] To achieve the above-mentioned purpose, the present invention provides the following technical solutions: a multi-purpose metrology and detection work platform, comprising a measuring cup, a limiting net and a pressing plate, the bottom of the pressing plate is fixedly connected to the limiting net, a measuring cup matched with the pressing plate and the limiting net is arranged below the pressing plate, the limiting net is a mesh structure made of hard metal, and the limiting net has a certain anti-deformation performance, the outer ring of the limiting net is a circular ring structure made of metal, the shape and size of the limiting net are just matched with the cup mouth of the measuring cup, the outer ring metal of the limiting net can be just embedded in the cup mouth of the measuring cup, and after embedding, it cannot be further penetrated into the measuring cup, after the limiting net is embedded in the cup mouth of the measuring cup, the mesh structure of the hard metal material of the limiting net will be in the same horizontal plane as the plane where the circular cup mouth of the measuring cup is located, a sliding limiting groove is respectively opened on both sides of the inner side wall of the device shell, and the position of the pressing plate close to the sliding limiting groove is respectively fixedly connected with an adapting sliding ear matched with the sliding limiting groove.
[0007] By adopting the above technical scheme, the limiting net is a mesh structure of hard metal material, which has certain anti-deformation performance. The outer ring of the limiting net is a circular ring structure of metal material, and its shape and size are just adapted to the mouth of the measuring cup, wherein the mouth of the measuring cup is specially designed to be a conical shape, which complements the conical surface of the outer ring metal structure of the limiting net. At the same time, the outer ring metal of the limiting net can be just embedded in the mouth of the measuring cup, and after embedding, it cannot further penetrate into the measuring cup. After the limiting net is embedded in the mouth of the measuring cup, the mesh structure of the hard metal material of the limiting net will be in the same horizontal plane as the plane where the circular mouth of the measuring cup is located. The adapting sliding ears are respectively fixed on both sides of the pressing plate and slide in the sliding limiting groove. Because the pressing plate is rotatably connected to the connecting column, the pressing plate is stationary and no longer rotates relative to the measuring cup below during the lifting process, thereby avoiding the pressing plate from generating a torsional force on the measuring cup during the instantaneous process of abutting against the measuring cup.
[0008] The present invention is further configured such that a rotating ring is rotatably connected to the outer side of the measuring cup, and a cup handle is fixedly connected to a side of the rotating ring away from the measuring cup.
[0009] By adopting the above technical solution, the function of the cup handle is to facilitate taking the measuring cup. The cup handle can be rotated on the outer wall of the measuring cup through the rotating ring, which is convenient for taking and prevents the measuring cup from rotating in the device and being unable to deform after colliding with other fixed parts and causing damage to the device.
[0010] The present invention is further configured such that a connecting column is rotatably connected to the upper portion of the pressing plate, a rotating port is fixedly connected to the other end of the connecting column away from the pressing plate, and a matching water injection port is provided in the whole composed of the pressing plate, the connecting column and the rotating port.
[0011] By adopting the above technical solution, a connecting column is rotatably connected to the top of the pressing plate, and the other end of the connecting column away from the pressing plate is fixedly connected to the rotating port. A matching water injection port is provided in the whole composed of the pressing plate, the connecting column and the rotating port. The pressing plate, the connecting column, the rotating port and the water injection port together form a whole. When the pressing plate is abutted and fixed to the mouth of the measuring cup, water can be injected into the measuring cup through the water injection port.
[0012] The present invention is further configured such that an externally threaded disk is provided at a middle position of the connecting column away from the pressing disk and the rotating mouth, a device shell is provided on the outer side of the externally threaded disk, an internally threaded wall matched with the externally threaded disk is provided on the inner side wall of the device shell, and drainage holes should be provided on the connecting column near the pressing disk and the mouth of the measuring cup.
[0013] By adopting the above technical solution, a whole set of structures including the external threaded disk is rotated by rotating the rotating port at the uppermost end of the rotating device, and the external threaded disk and the internal threaded wall with the external threaded disk cooperate with each other, so that the whole set of structures can complete the control of the lifting and lowering of the structure during the rotation inside the device shell, and further realize the pressing and limiting and loosening of the measuring cup by the pressing disk.
[0014] The present invention is further configured such that a water outlet matching with the measuring cup is opened inside the bottom end of the device shell, a gravity measuring device matching with the measuring cup is arranged inside the water outlet, a plurality of groups of horizontal adjustment legs are arranged on the outside of the bottom end of the device shell, and a reading LCD screen is arranged on the surface of the outside of the bottom end of the device shell near the measuring cup.
[0015] By adopting the above technical solution, the water outlet allows excess water to flow out of the device, and the downward pressure generated by the gravity of the upper object is measured by the gravity measuring device. The value measured by the gravity measuring device is displayed on the readout LCD screen, and the stem group horizontal adjustment legs can adjust the levelness of the entire device.
[0016] In summary, the present invention mainly has the following beneficial effects:
[0017] The present invention uses a mesh structure of a hard metal material as the limiting net, which has a certain anti-deformation performance. After the limiting net is embedded in the mouth of the measuring cup, the mesh structure of the hard metal material of the limiting net will be in the same horizontal plane as the plane where the circular mouth of the measuring cup is located, limiting the object to be measured with a density less than the water density to float on the water surface, resulting in the water drainage method being unable to measure the precise volume of the object. When the limiting net leaves the floating object and the measuring cup, the object floats spontaneously and the water level drops. At this time, the total weight remains unchanged, thereby solving the problem that traditional devices are difficult to measure the precise volume of the object to be measured with a density less than the water density.

[0025] The following will be combined with the accompanying drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. 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.
[0026] The following describes an embodiment of the present invention based on its overall structure.
[0027] A multi-purpose measurement and testing work platform, such as Figure 1-Figure 2 As shown, the main structure includes a measuring cup 1, a limiting net 4 and a pressing plate 5. The bottom of the pressing plate 5 is fixedly connected to the limiting net 4. A measuring cup 1 adapted to the pressing plate 5 and the limiting net 4 is arranged below the pressing plate 5. The limiting net 4 is a mesh structure made of hard metal material and has a certain anti-deformation performance. The outer ring of the limiting net 4 is a circular ring structure made of metal material, such as Figure 3-Figure 4 As shown, its shape and size are just matched with the mouth of the measuring cup 1, wherein the mouth of the measuring cup 1 is specially designed to be conical, which complements the conical surface of the outer metal ring structure of the limiting net 4, and at the same time, the outer metal of the limiting net 4 can be just embedded in the mouth of the measuring cup 1, and cannot be further penetrated into the measuring cup 1 after embedding. After the limiting net 4 is embedded in the mouth of the measuring cup 1, the mesh structure of the hard metal material of the limiting net 4 will be on the same horizontal plane as the plane where the circular mouth of the measuring cup 1 is located. At this time, the maximum water storage volume of the structure composed of the measuring cup 1 and the limiting net 4 is v, and the weight is m.
[0028] Among them, the surface of the outer wall of the measuring cup 1 should be specially treated or provided with a special coating. When the outer wall contacts the pure water used for measurement, the water cannot form water droplets hanging on the outer cup wall, and only stays on the outer wall of the measuring cup 1 for a very short time before flowing down in streams to leave the measuring cup 1. The nano-scale super-hydrophobic structure of the lotus leaf surface can be used as a reference. As long as the ideal effect of preventing water from staying on the outer wall of the measuring cup 1 and being infinitely close to dry can be achieved, it will be fine.
[0029] On the basis of the above structure, in this embodiment, the outer side of the measuring cup 1 is rotatably connected to a rotating ring 2, and the side of the rotating ring 2 away from the measuring cup 1 is fixedly connected to a cup handle 3. Figure 3 As shown, the function of the cup handle 3 is to facilitate taking the measuring cup 1. The cup handle 3 can be rotated on the outer wall of the measuring cup 1 through the rotating ring 2, which makes it easy to take and prevents the measuring cup 1 from rotating in the device and being unable to deform after colliding with other fixed parts and causing damage to the device.
[0030] A connecting column 10 is rotatably connected to the top of the pressing plate 5, and a rotating port 11 is fixedly connected to the other end of the connecting column 10 away from the pressing plate 5. A matching water injection port 12 is provided in the whole composed of the pressing plate 5, the connecting column 10 and the rotating port 11. The pressing plate 5, the connecting column 10, the rotating port 11 and the water injection port 12 together form a whole. When the pressing plate 5 is abutted and fixed against the mouth of the measuring cup 1, water can be injected into the measuring cup 1 through the water injection port 12.
[0031] Among them, the connecting column 10 should be provided with drainage holes near the pressing plate 5 and the mouth of the measuring cup 1. In actual use, it is difficult to accurately control the amount of water injected. As long as the measuring cup 1 is filled with water, the water above the water level at the mouth of the measuring cup 1 will spontaneously flow out through the holes. At the same time, when in use, the operator needs to grasp the rotating mouth 11 with his fingers to rotate it. The outer side of the rotating mouth 11 can be roughened or equipped with a structure of anti-slip material to further facilitate the operator's rotation process during actual use.
[0032] On the basis of the above structure, in this embodiment, an externally threaded disk 6 is provided at a middle position of the connecting column 10 away from the pressing disk 5 and the rotating port 11, a device housing 13 is provided on the outer side of the externally threaded disk 6, and an internally threaded wall 7 matched with the externally threaded disk 6 is provided on the inner side wall of the device housing 13. When in use, the entire set of structures including the externally threaded disk 6 is rotated by rotating the rotating port 11 at the uppermost end of the device, and the externally threaded disk 6 and the internally threaded wall 7 with the externally threaded disk 6 cooperate to control the lifting of the structure during the rotation of the entire set of structures inside the device housing 13. In order to further realize the crimping limit and loosening of the measuring cup 1 by the pressing plate 5, a sliding limit groove 8 is respectively opened on both sides of the surface of the internal threaded wall 7, and the pressing plate 5 is fixedly connected with an adapting sliding ear 9 matching the sliding limit groove 8 at a position close to the sliding limit groove 8. The adapting sliding ears 9 are respectively fixed on both sides of the pressing plate 5 and slide in the sliding limit groove 8. Since the pressing plate 5 is rotatably connected with the connecting column 10, the pressing plate 5 is stationary relative to the measuring cup 1 below during the lifting process, thereby preventing the pressing plate 5 from generating a torsional force on the measuring cup 1 during the instantaneous process of abutting against the measuring cup 1.
[0033] A water outlet 15 cooperating with the measuring cup 1 is provided inside the bottom end of the device housing 13 to allow excess water to flow out of the device. A gravity measuring device 14 cooperating with the measuring cup 1 is provided inside the water outlet 15 to measure the downward pressure generated by the gravity of the upper object. A plurality of groups of horizontal adjustment legs 16 are provided on the outer side of the bottom end of the device housing 13 to adjust the horizontality of the entire device. A reading LCD screen 17 is provided on the surface of the outer side of the bottom end of the device housing 13 near the measuring cup 1, and the value measured by the gravity measuring device 14 is displayed on the reading LCD screen 17.
[0034] When in use, firstly, the object to be measured is placed into the device through the measuring cup 1, and the measuring cup 1 is placed on the gravity measuring device 14. At this time, the weight of the object can be measured as m1. Then, the operator rotates the rotating mouth 11 to make the pressing plate 5 and the limiting net 4 completely abut against the mouth of the measuring cup 1, and starts to inject water into the measuring cup 1 through the water injection port 12 until the water overflows the horizontal position of the mouth of the measuring cup 1 and the limiting net 4. Then, the rotating mouth 11 is rotated in the opposite direction to make the pressing plate 5 and the limiting net 4 leave the measuring cup 1. At this time, the total mass of the object and water in the measuring cup 1 can be measured as m=m1+m2, as shown in FIG. Figure 5-Figure 6 As shown, in this stage, m and the measured m2 are known quantities, and then m2, that is, the weight of water, is obtained, and the volume v2 of water is further obtained, and the maximum water storage volume of the structure composed of the measuring cup 1 and the limiting net 4 is v, which is a known quantity, and the object volume v1=v-v2 is further obtained. Because it is near the surface of the earth, the object density ρ1=m1 / v1 can be further obtained.
[0035] Although an embodiment of the present invention has been shown and described, this specific embodiment is merely an explanation of the present invention and is not a limitation of the invention. The specific features, structures, materials or characteristics described may be combined in a suitable manner in any one or more embodiments or examples. After reading this specification, those skilled in the art may make modifications, substitutions and variations to the embodiments without creative contributions as needed without departing from the principles and purpose of the present invention. However, as long as they are within the scope of the claims of the present invention, they are protected by patent law.
