In this specification, the illustrative expressions of the above terms do not necessarily refer to the same implementation or example. Furthermore, the specific features, structures, materials, or characteristics described may be combined in any suitable manner in one or more embodiments or examples.

[0042] Combination Figures 1 to 5 As shown, this embodiment provides a rack, including: a first rack 10 and a second rack 20, the first rack 10 and the second rack 20 being arranged along a first horizontal direction (i.e., the first direction). Figure 1 The y-axis direction is set, and the first frame 10 and the second frame 20 can be spliced ​​together;

[0043] At least one first independent frame 11 is provided inside the first frame 10. The first independent frame 11 is positioned and engaged with the first frame 10 through the first positioning member 30. The first independent frame 11 can be locked with the first frame 10.

[0044] At least one second independent frame 21 is provided inside the second frame 20. The second independent frame 21 is positioned and engaged with the second frame 20 by a second positioning member 40, and the second independent frame 21 can be positioned relative to the second frame 20 in a second horizontal direction (i.e., the second direction) via the second positioning member 40. Figure 1 The second independent frame 21 can be locked to the second frame 20 (moving in the x-axis direction);

[0045] Measurement modules are installed on both the first independent frame 11 and the second independent frame 21.

[0046] The rack provided in this embodiment, by setting up a first rack and a second rack that can be spliced ​​together, can be disassembled as a whole, which can realize the disassembly and transportation of the rack, reducing the difficulty of handling the rack. Moreover, disassembling the rack reduces the weight of a single rack, making the installation process easier and reducing the use of manpower and material resources. In addition, disassembling the rack also reduces the footprint of a single rack, which can better adapt to the site conditions of different workshops and avoid the problem of cramped installation caused by limited workshop space and a large footprint of the overall rack. By setting up a first independent rack on the first rack and a second independent rack on the second rack, it is easier to adjust the positions of the first and second independent racks, making their positions more precise. After the first and second independent racks are positioned and aligned with the first rack, they are locked together. In subsequent installation processes, there is no need to adjust the positions of the first and second independent racks again, and no need for on-site adjustments by technicians. This reduces the difficulty of adjustment, saves time and effort, and avoids the problems of inconvenient module adjustment or the need for on-site adjustments by technicians that occur when building modules on the overall rack after installation.

[0047] Based on the above embodiments, as an optional implementation method, combined with Figure 3 and Figure 6 As shown, the first positioning component 30 includes a first positioning block 31 and a second positioning block 32. The first positioning block 31 is disposed on the first frame 10, and the second positioning block 32 is disposed on the first independent frame 11. The second positioning block 32 has a first recess 321, and the first positioning block 31 has a first protrusion 311. The first protrusion 311 extends into the first recess 321 and engages with it, achieving rapid engagement and positioning of the first protrusion 311 and the first recess 321, thus reducing the positioning difficulty between the first independent frame 11 and the first frame 10. Alternatively, the second positioning block 32 may have a first protrusion, and the first positioning block 31 may have a first recess. The first protrusion extends into the first recess and engages with it, achieving rapid engagement and positioning of the first protrusion and the first recess.

[0048] Based on the above embodiments, as an optional implementation, the first recess 321 can be a V-shaped groove, and the first protrusion 311 has inclined surfaces that contact the two sides of the V-shaped groove, so that the first protrusion 311 can fit snugly with the first recess 321, thereby improving the positioning accuracy of the first independent frame 11 and the first frame 10, and also improving the stability of the connection between the first independent frame 11 and the first frame 10. Of course, in other optional embodiments, the first recess 321 can also adopt other shapes, as long as it can ensure that the first recess 321 and the first protrusion 321 can fit snugly, thereby improving the stability of the docking.

[0049] Based on the above embodiments, as an optional implementation, the first recess 321 faces the vertical direction (i.e., the third direction). Figure 1 The first independent frame 11 is recessed in the z-axis direction, and the first protrusion 311 protrudes in the third direction. Furthermore, the first independent frame 11 is positioned and engaged with the first frame 10 via two first positioning members 30, which are arranged vertically. Specifically, two second positioning blocks 32 are arranged vertically at opposite ends of the first independent frame 11, and the first frame 10 is provided with two first positioning blocks 31 that respectively engage with the two second positioning blocks 32. That is, the first independent frame 11 has one second positioning block 32 at its upper and lower ends in the vertical direction, and the first frame 10 has first positioning blocks 31 that engage with these two second positioning blocks 32. The first recesses 321 of the two second positioning blocks 32 are arranged in opposite directions, or the first protrusions 311 of the two second positioning blocks 32 are arranged in opposite directions. That is, if the second positioning block 32 is set with a first recess 321, one first recess 321 is recessed downward in the vertical direction, and the other first recess 321 is recessed upward in the vertical direction; if the second positioning block 32 is set with a first protrusion, one first protrusion is protruding upward in the vertical direction, and the other first protrusion is protruding downward in the vertical direction. Thus, this arrangement allows the first independent frame 11 to be more stably engaged with the first frame 10 and improves the positioning accuracy. It also facilitates the subsequent locking of the first independent frame 11 onto the first frame 10.

[0050] In this embodiment, the first positioning block 31 and the second positioning block 32 are arranged on the same plane, which helps to increase the contact area between the first positioning block 31 and the second positioning block 32 and improve the stability of their docking.

[0051] Based on the above embodiments, as an optional implementation, the first positioning block 31 can be mounted on the first frame 10 by means of a pin, and the second positioning block 32 can be mounted on the first independent frame 11 by means of a pin. As an optional implementation, the first positioning block 31 and the second positioning block 32 are provided with set screw holes, which can realize the efficient removal of the first positioning block 31 and the second positioning block 32.

[0052] Based on the above embodiments, as an optional implementation, a connector 60 is further included. The connector is used to lock the first independent frame 11 and the first frame 10 together. After the first independent frame 11 and the first frame 10 are positioned and engaged, they are locked together by the connector 60. During subsequent installation, there is no need to adjust the position of the first independent frame 11, and no need for on-site adjustments by technicians, reducing the difficulty of adjustments and saving time and effort. As an optional implementation, the connector 60 includes a connecting plate and fasteners passing through the connecting plate, such as bolts or screws.

[0053] Based on the above embodiments, as an optional implementation, a first independent frame 11 is provided within the first frame 10. A height measurement module is mounted on the first independent frame 11. The height measurement module is relatively heavy and difficult to adjust; by using the first independent frame 11, it can be adjusted before locking. Of course, those skilled in the art can also install other modules requiring adjustment on the first independent frame 11 according to actual conditions.

[0054] Based on the above embodiments, as an optional implementation method, combined with Figure 4 , Figure 5 , Figure 7 and Figure 8 As shown, the second positioning component 40 includes a third positioning block 41 and a fourth positioning block 42. The third positioning block 41 is disposed on the second frame 20, and the fourth positioning block 42 is disposed on the second independent frame 21. The third positioning block 41 has a first protrusion 411, and the fourth positioning block 42 has a first groove 421. The first groove 421 extends horizontally in a second direction. By having the first protrusion 411 extend into the first groove 421 and engage, the first protrusion 411 and the first groove 421 can quickly engage and position, reducing the positioning difficulty of the second frame 20 and the second independent frame 21. Furthermore, the first groove 421 extends horizontally in a second direction, allowing the first protrusion 411 to move along the first groove 421 in the second horizontal direction, thereby enabling the second independent frame 21 to move relative to the second frame 20 in the second horizontal direction, allowing for more precise adjustment of the position of the second independent frame 21 in the second horizontal direction. As another alternative implementation, the fourth positioning block 42 may be provided with a first protrusion and the third positioning block 41 may be provided with a first groove. The first protrusion can be inserted into the first groove to engage, thereby achieving rapid engagement and positioning of the first protrusion and the first groove.

[0055] Based on the above embodiments, as an optional implementation, the first groove 421 can be a V-shaped groove extending along the second horizontal direction, and the first protrusion 411 has inclined surfaces that contact the two sides of the V-shaped groove, so that the first protrusion 411 can fit snugly with the first groove 421, thereby improving the positioning accuracy of the second independent frame 21 and the second frame 20, and helping to improve the stability of the connection between the second independent frame 21 and the second frame 20. Of course, in other optional embodiments, the first groove 421 can also adopt other shapes, as long as it can ensure that the first groove 421 and the first protrusion 411 can fit snugly and improve the stability of the docking.

[0056] Based on the above embodiments, as an optional implementation, the first groove 421 is recessed in the vertical direction, and the first protrusion 411 protrudes in the vertical direction. Furthermore, the second independent frame 21 is positioned and engaged with the second frame 20 by two second positioning members 40, which are arranged vertically. Specifically, two fourth positioning blocks 42 are arranged vertically at opposite ends of the second independent frame 21, and the second frame 20 is provided with two third positioning blocks 41 that respectively cooperate with the two fourth positioning blocks 42. That is, the second independent frame 21 has one fourth positioning block 42 at its upper and lower ends in the vertical direction, and the second frame 20 has third positioning blocks 41 that cooperate with the two fourth positioning blocks 42. The first grooves 421 of the two fourth positioning blocks 42 are arranged in opposite directions, or the first protrusions of the two fourth positioning blocks 42 are arranged in opposite directions. That is, if the fourth positioning block 42 is set with a first groove 421, one first groove 421 is recessed downwards in the vertical direction, and the other first groove 421 is recessed upwards in the vertical direction; if the fourth positioning block 42 is set with a first protrusion, one first protrusion is raised upwards in the vertical direction, and the other first protrusion is raised downwards in the vertical direction. Thus, this arrangement allows the second independent frame 21 to be more stably engaged with the second frame 20 and improves the positioning accuracy. It also facilitates the subsequent locking of the second independent frame 21 onto the second frame 20.

[0057] In this embodiment, the third positioning block 41 and the fourth positioning block 42 can be used to connect independent racks that are not on the same plane and need to be adjusted in the second horizontal direction. The third positioning block 41 and the fourth positioning block 42 can realize the adjustability of the independent rack in the second direction.

[0058] Based on the above embodiments, as an optional implementation, the third positioning block 41 can be mounted on the second frame 20 by means of a pin, and the fourth positioning block 42 can be mounted on the second independent frame 21 by means of a pin. As an optional implementation, the third positioning block 41 and the fourth positioning block 42 are provided with set screw holes, which can realize the efficient removal of the third positioning block 41 and the fourth positioning block 42.

[0059] Based on the above embodiments, as an optional implementation, a connector is also included. The connector is used to lock the second independent frame 21 and the second frame 20 together. After the second independent frame 21 and the second frame 20 are positioned and engaged, they are locked together using the connector. This eliminates the need for further adjustment of the position of the second independent frame 21 during subsequent installation, reducing the difficulty of on-site adjustments by technicians and saving time and effort. As an optional implementation, the connector includes a connecting plate and fasteners passing through the connecting plate, such as bolts or screws.

[0060] Based on the above embodiments, as an optional implementation, two second independent frames 21 are provided within the second frame 20. The two second independent frames 21 are arranged along a first horizontal direction, with one second independent frame 21 equipped with a weighing measurement module and the other with a diameter measurement module. The weighing measurement module and the diameter measurement module are relatively heavy and difficult to adjust; by using two separate second independent frames 21, they can be adjusted before locking. Of course, those skilled in the art can also install other modules requiring adjustment on the second independent frames 21 according to actual conditions.

[0061] Based on the above embodiments, as an optional implementation, the lengths of the first grooves 421 in the two second positioning members 40 extending along the second horizontal direction may be equal or unequal. For example, combined with Figure 7 and Figure 8 As shown, the length of the first groove 421 in one of the second positioning members 40 (i.e., the second positioning member 40 connected to the diameter measuring module) extending along the second horizontal direction is L1, and the length of the first groove 421 in the other second positioning member 40 (i.e., the second positioning member 40 connected to the weighing measuring module) extending along the second horizontal direction is L2. L1 can be greater than L2. Of course, in some alternative embodiments, L1 can also be equal to or less than L2. Those skilled in the art can adjust the length of the first groove 421 extending along the second horizontal direction in each of the second positioning members 40 according to the actual situation.

[0062] Based on the above embodiments, as an optional implementation, the length of the first protrusion 411 in the second positioning member 40 extending along the second horizontal direction can be equal to the length of the first groove 421 extending along the second horizontal direction. Of course, it can also be greater than or less than the length of the first groove 421 extending along the second horizontal direction, as long as it can ensure that the first protrusion 411 and the first groove 421 can be engaged and positioned, and the first protrusion 411 can move within the first groove 421 so that the second independent frame 21 can move relative to the second frame 20 along the second horizontal direction.

[0063] Based on the above embodiments, as an optional implementation method, combined with Figure 9 As shown, it also includes a third positioning component 50, which includes a fifth positioning block 51 and a sixth positioning block 52. The fifth positioning block 51 is disposed on the first frame 10, and the sixth positioning block 52 is disposed on the second frame 20. The sixth positioning block 52 has a second recess 521, and the fifth positioning block 51 has a second protrusion 511. The second protrusion 511 extends into the second recess 521 and engages with it, achieving rapid engagement and positioning of the second protrusion 511 and the second recess 521. This reduces the positioning difficulty of the first frame 10 and the second frame 20 and facilitates rapid assembly of the first frame 10 and the second frame 20. Alternatively, the sixth positioning block 52 may have a second protrusion, and the fifth positioning block 51 may have a second recess. The second protrusion extends into the second recess and engages with it, achieving rapid engagement and positioning of the second protrusion and the second recess.

[0064] Based on the above embodiments, as an optional implementation, the second recess 521 can be a V-shaped groove, and the second protrusion 511 has inclined surfaces that contact the two sides of the V-shaped groove, so that the second protrusion 511 can fit snugly with the second recess 521, thereby improving the positioning accuracy of the first frame 10 and the second frame 20 and improving the stability of the connection between the first frame 10 and the second frame 20. Of course, in other optional embodiments, the second recess 521 can also adopt other shapes, as long as it can ensure that the second recess 521 and the second protrusion 511 can fit snugly and improve the stability of the docking.

[0065] Based on the above embodiments, as an optional implementation, the second recessed portion 521 is recessed towards the first horizontal direction, and the second protruding portion 511 protrudes towards the first horizontal direction, so that the first frame 10 and the second frame 20 are spliced ​​and positioned in the first horizontal direction.

[0066] In this embodiment, the fifth positioning block 51 and the sixth positioning block 52 are arranged on the same plane, which helps to increase the contact area between the fifth positioning block 51 and the sixth positioning block 52 and improve the stability of their docking.

[0067] Based on the above embodiments, as an optional implementation, the fifth positioning block 51 can be mounted on the first frame 10 by means of a pin, and the sixth positioning block 52 can be mounted on the second frame 20 by means of a pin. As an optional implementation, the fifth positioning block 51 and the sixth positioning block 52 are provided with set screw holes, which can realize the efficient removal of the fifth positioning block 51 and the sixth positioning block 52.

[0068] Based on the above embodiments, as an optional implementation, a connector 60 is further included, which is used to lock the first frame 10 and the second frame 20 together. After the first frame 10 and the second frame 20 are positioned and engaged, they are locked together by the connector 60, thereby fixing the first frame 10 and the second frame 20 into a single unit. As an optional implementation, the connector includes a connecting plate and fasteners passing through the connecting plate, the fasteners including bolts or screws, etc.

[0069] Before transportation, the rack provided in this embodiment is positioned and engaged by the first positioning member 30 and the first rack 10, and then locked by the connecting member 60. The second independent rack 21 and the second rack 20 are then positioned and engaged by the second positioning member 40. After adjusting their positions in the second horizontal direction, the second independent rack 21 and the second rack 20 are locked by the connecting member 60. During transportation, the first rack 10 and the second rack 20 can be transported separately. When using the rack, the first rack 10 and the second rack 20 are positioned and engaged by the third positioning member 50, and then connected by the connecting member 60 to form a complete rack.
