Description

Technical Field

[0001] This application relates to the field of cabinet installation technology, and in particular to a levelness detection device. Background Technology

[0002] Laboratory safety cabinets are specialized equipment used to safely store various hazardous chemicals or gas cylinders. Their main purpose is to achieve isolation, ventilation, leak prevention, and fire prevention, thereby effectively reducing the risks of fire, poisoning, corrosion, or explosion.

[0003] The safety cabinet has four support legs at its bottom corners. The final step in delivering the cabinet is placing these legs onto the required mounting surface. However, the actual site conditions vary, and the mounting surface may differ in depth. Therefore, a laser level is used to check the levelness of the mounting surface. The results of this check and measurement provide technical support for the subsequent on-site installation of the cabinet.

[0004] When using a laser level to test the levelness of the mounting surface, the laser line becomes blurred or even invisible under bright ambient light (especially outdoors or in a well-lit laboratory), which seriously affects the reading and results in poor accuracy of the installation surface levelness test. In addition, it is difficult for the laser level to find a unified test benchmark for four relatively isolated measurements, making it difficult to unify the test data, resulting in low test efficiency and affecting the stability of the subsequent installation of the cabinet. Summary of the Invention

[0005] To address the problem that when using a laser level to test the levelness of an installation surface, the laser line becomes blurred or even invisible under bright ambient light (especially outdoors or in a well-lit laboratory), severely affecting the readings and resulting in poor accuracy and low efficiency in detecting the levelness of the installation surface, thus impacting the stability of the subsequent installation of the mounting cabinet, this application provides a levelness testing device with the following technical solution: It includes four support rods mounted on the installation surface, each of the four support rods being threaded with a connecting block. The four connecting blocks together form an installation area that matches the mounting cabinet. A leveling rod passes between each pair of adjacent connecting blocks. A level is mounted on each of the four leveling rods, and a measuring unit is mounted on each of the four connecting blocks to measure the height between the connecting block and the installation surface.

[0006] In one specific implementation scheme, each of the four support rods has a horizontal base plate at one end facing the mounting surface, and the four horizontal base plates are respectively mounted on the mounting surface.

[0007] In one specific implementation, the measuring unit includes mounting holes respectively opened on the connecting block, and a scale matching the mounting hole is inserted into the mounting hole. The scale is vertically arranged and the end of the scale facing the mounting surface is mounted on a horizontal base.

[0008] In one specific implementation, a support nut is threaded onto the support rod, the support nut being located between the connecting block and the horizontal base, with the end face of the support nut facing the connecting block in contact with the connecting block.

[0009] In one specific implementation scheme, all four leveling rods are smooth rods, and the four levels are respectively set on the outer edges of the four smooth rods. Each of the four connecting blocks has a limiting hole that matches the smooth rod, and the smooth rod passes through the limiting holes on two oppositely arranged connecting blocks.

[0010] In one specific implementation, the four optical rods are provided with anti-detachment screws at both ends, and anti-detachment nuts are threaded onto the anti-detachment screws. Two connecting blocks located on the same optical rod are located between two anti-detachment nuts.

[0011] In one specific implementation, the outer edge of the light rod is provided with a limiting groove that matches the level, and the level is mounted in the limiting groove.

[0012] In one specific implementation, the level is provided with a mounting bolt, and the bottom of the limiting groove is provided with a threaded groove that matches the mounting bolt. The end of the mounting bolt facing the guide rod is threaded into the threaded groove.

[0013] In one specific implementation scheme, all four leveling rods are threaded rods, the four levels are respectively set on the outer edges of the four threaded rods, and the four connecting blocks are respectively provided with threaded holes that match the threaded rods. The threaded rods pass through the threaded holes on two opposite connecting blocks and are threadedly connected to the threaded holes.

[0014] In one specific implementation, the threaded rod is threaded with a magnetic material nut, and the level is provided with a magnetic accumulator, which is attracted to the outer edge of the magnetic material nut.

[0015] In summary, this application offers the following beneficial technical effects: Operators adjust the size of the installation area according to the dimensions of the mounting cabinet, then place four support rods on the mounting surface and adjust their height positions on the connections. Simultaneously, they observe the liquid column of the level until the ends of all four support rods facing the mounting surface are in contact with it, and the liquid columns of the four level are in the center position. At this point, the height data between the connecting blocks and the mounting surface measured by the measuring unit is read, thus determining the levelness of the four connecting blocks on the mounting surface. Based on this levelness and measurement results, technical support is provided for the subsequent on-site installation of the mounting cabinet. This approach abandons the principle of relying on visual observation of laser lines in related technologies, instead using a mechanical structure combined with a bubble level for levelness measurement. It directly measures the actual height and relative height difference of the four corresponding positions of the mounting cabinet's four legs. The measurement data is directly used to guide installation, improving the accuracy of mounting surface measurement and greatly increasing inspection efficiency and the speed of subsequent installation decisions.

[0019] The following is in conjunction with the appendix Figure 1-2 This application will be described in further detail.

[0020] Example 1 Embodiment 1 of this application discloses a levelness detection device.

[0021] Reference Figure 1 The levelness detection device includes four support rods 1 mounted on a mounting surface. In this embodiment, the mounting surface can be the ground. A horizontal base 6 is fixedly connected to one end of each support rod 1 facing the mounting surface. The support rods 1 are mounted on the mounting surface via the horizontal base 6, which increases the contact area between the bottom of the support rod 1 and the mounting surface, thus improving the stability of the support rod 1. In this embodiment, the levelness detection device can be applied to the initial installation and testing of cabinets such as test cabinets, installation cabinets, and explosion-proof cabinets, and can also be applied to other fields requiring joint measurement of relative levelness; no limitations are imposed here.

[0022] Reference Figure 1 Each of the four support rods 1 is threaded with a connecting block 2. The four connecting blocks 2 together form an installation area 3 that matches the size of the mounting cabinet. A leveling rod 4 is inserted between each adjacent connecting block 2. This allows the operator to adjust the relative position of the four leveling rods 4 according to the actual length and width of the mounting cabinet, thereby adjusting the size of the installation area 3 to match the actual size of the mounting cabinet. A level 5 is installed on the outer edge of each of the four leveling rods 4. In this embodiment, the level 5 is a bubble level 5, and the distance from the level 5 to the connecting blocks 2 on both sides of the length direction is equal. Each of the four connecting blocks 2 is provided with a measuring unit to measure the height between the connecting block 2 and the mounting surface.

[0023] Therefore, the operator adjusts the size of the installation area 3 according to the dimensions of the installation cabinet, then sets up the four support rods 1 on the installation surface, adjusts the height of the connecting blocks 2 on the support rods 1, and observes the liquid column of the level 5 until the ends of the four support rods 1 facing the installation surface are all in contact with the installation surface, and the liquid columns of the four level 5 are in the middle position. At this time, the height data between the connecting blocks 2 and the installation surface measured by the measuring unit is read, thus determining the levelness of the corresponding four connecting blocks 2 on the installation surface. Based on this levelness and measurement results, technical support is provided for the subsequent on-site installation of the installation cabinet, such as adjusting the height of the four legs at the bottom of the installation cabinet or grinding or raising the installation surface. This method abandons the principle of relying on the naked eye to observe the laser line in related technologies, and instead uses a mechanical structure combined with a bubble level 5 to measure the levelness, directly measuring the actual height and relative height difference of the corresponding positions of the four legs of the installation cabinet. The measurement data is directly used to guide the installation, improving the accuracy of the installation surface measurement, greatly improving the detection efficiency and the speed of subsequent installation decisions.

[0024] Reference Figure 1 The measuring unit includes mounting holes 7 respectively opened on the connecting block 2. A scale 8 matching the size of the mounting hole 7 is inserted into the mounting hole 7. The scale 8 is set vertically and the end of the scale 8 facing the mounting surface is mounted on the horizontal base 6. In this embodiment, the scale 8 is a steel ruler. The levelness of the mounting surface is known by reading the size value corresponding to the top end face of the connecting block 2 and the scale 8. If the read size is consistent, it means that the levelness of the four horizontal bases 6 on the mounting surface is consistent. If the read size is inconsistent, it means that the levelness of the four horizontal bases 6 on the mounting surface is inconsistent, that is, the mounting surface has different depths.

[0025] Reference Figure 1 A support nut is threaded onto the support rod 1. The support nut is located between the connecting block 2 and the horizontal base plate 6, and the end face of the support nut facing the connecting block 2 is in contact with the connecting block 2. The support nut is used to support and position the connecting block 2 in the vertical direction of the support rod 1, thereby improving the stability of the position of the connecting block 2.

[0026] Reference Figure 1 The four leveling rods 4 are all smooth rods 10, and four levels 5 are respectively set on the outer edges of the four smooth rods 10. Each of the four connecting blocks 2 has a limiting hole 11 matching the size of the smooth rod 10. The smooth rod 10 passes through the limiting holes 11 on two oppositely arranged connecting blocks 2. In this embodiment, the size of the limiting hole 11 is slightly larger than the diameter of the smooth rod 10, and the two limiting holes 11 on the same connecting block 2 are the same size. This allows the smooth rod 10 to slide more easily within the limiting hole 11, but still provides some resistance. The operator can adjust the size of the installation area 3 by dragging the smooth rod 10 and the connecting block 2 to create relative displacement between them.

[0027] Reference Figure 1 Four guide rods 10 are fixedly connected to their ends with anti-detachment screws 12, and anti-detachment nuts 9 are threaded onto the anti-detachment screws 12. Two connecting blocks 2 located on the same guide rod 10 are positioned between two anti-detachment nuts 9. The anti-detachment nuts 9 limit the position of the connecting blocks 2, reducing the possibility of the connecting blocks 2 detaching from the guide rod 10. A limiting groove 14 matching the size of the level 5 is opened on the outer edge of the guide rod 10. The level 5 is mounted in the limiting groove 14, which limits the position of the level 5, improving the stability of the level 5 mounted on the guide rod 10. A mounting bolt passes through the level 5. A threaded groove matching the size of the mounting bolt is opened on the bottom of the limiting groove 14. The end of the mounting bolt facing the guide rod 10 is threaded into the threaded groove. The operator can remove the level 5 from the guide rod 10 by removing the bolt, achieving a detachable connection of the level 5, which is more flexible and facilitates subsequent replacement of the level 5.

[0028] The implementation principle of Embodiment 1 of this application is as follows: The operator drags the light rod 10 and the connecting block 2 to make the light rod 10 and the connecting block 2 relative to each other, so that the size of the installation area 3 can be adjusted according to the size of the installation cabinet. Then, four horizontal base plates 6 are set on the installation surface, and the height position of the support rod 1 on the connection is adjusted respectively. At the same time, the liquid column of the level instrument 5 is observed until the bottom surface of the four horizontal base plates 6 is in contact with the installation surface and the liquid column of the four level instruments 5 is in the middle position. At this time, the dimension value corresponding to the top end face of the connecting block 2 and the scale 8 is read to know the levelness of the installation surface. If the readings are consistent, it means that the levelness of the four horizontal base plates 6 on the installation surface is consistent. If the readings are inconsistent, it means that the levelness of the four horizontal base plates 6 on the installation surface is inconsistent, that is, there is a situation of uneven depth of the installation surface. Based on the levelness and measurement results, technical support is provided for the on-site installation of the installation cabinet, such as adjusting the height of the four support legs at the bottom of the installation cabinet or grinding or raising the installation surface.

[0029] Abandoning the principle of relying on visual observation of laser lines in related technologies, the laser level 5 uses a mechanical structure combined with a bubble level 5 to measure levelness. It directly measures the actual height and relative height difference of the four legs of the installation cabinet. The measurement data is directly used to guide the installation, which improves the accuracy of the installation surface measurement and greatly improves the detection efficiency and the speed of subsequent installation decisions.

[0030] Example 2 Reference Figure 2 The difference between Embodiment 2 and Embodiment 1 is that all four leveling rods 4 are threaded rods 15, and four levels 5 are respectively set on the outer edge of the four threaded rods 15. Each of the four connecting blocks 2 has a threaded hole 16 that matches the size of the threaded rod 15, and the two threaded holes 16 on the same connecting block 2 have the same size. The threaded rod 15 passes through the threaded holes 16 on two opposite connecting blocks 2 and is threadedly connected to the threaded holes 16. The operator can adjust the size of the installation area 3 according to the size of the installation cabinet by rotating the threaded rod 15 to make the threaded rod 15 and the connecting block 2 produce relative displacement.

[0031] Reference Figure 2 Magnetic nuts 13 are threaded onto the threaded rod 15. In this embodiment, the magnetic nuts 13 can be made of materials containing iron, nickel, cobalt, or other magnetic alloys, and there is no limitation. A magnetic plate is provided on the level 5, which is attracted to the outer edge of the magnetic nut 13. The level 5 is magnetically attached to the magnetic nut 13, eliminating the need for tightening bolts as in Embodiment 1, thus facilitating quick installation and disassembly.

[0032] The implementation principle of Embodiment 1 of this application is as follows: The operator rotates the threaded rod 15 to make the threaded rod 15 and the connecting block 2 produce relative displacement, thereby adjusting the size of the installation area 3 according to the size of the installation cabinet. Then, four horizontal base plates 6 are set on the installation surface, and the height position of the support rod 1 on the connection is adjusted respectively. At the same time, the liquid column of the level instrument 5 is observed until the bottom surface of the four horizontal base plates 6 is in contact with the installation surface and the liquid column of the four level instruments 5 is in the middle position. At this time, the dimension value corresponding to the top end face of the connecting block 2 and the scale 8 is read to know the levelness of the installation surface. If the read dimensions are consistent, it means that the levelness of the four horizontal base plates 6 on the installation surface is consistent. If the read dimensions are inconsistent, it means that the levelness of the four horizontal base plates 6 on the installation surface is inconsistent, that is, there is a situation of uneven depth of the installation surface. Based on the levelness and measurement results, technical support is provided for the subsequent on-site installation of the installation cabinet, such as adjusting the height of the four support legs at the bottom of the installation cabinet or grinding or raising the installation surface.
