[0018] In order to make the purpose, technical solutions and advantages of the present application more clear, the present application will be further described in detail below with reference to the drawings and embodiments. It should be understood that the specific embodiments described herein are only used to explain the present application and not to limit the present application.

[0019] The present application proposes a power distribution box.

[0020] Embodiment 1

[0021] Reference Figures 1 to 6The distribution box includes a distribution box 1 and a support frame 13. Several distribution frames 11 for installing power distribution components are located in one side chamber of the distribution box 1. A main switch 12 for controlling several power distribution components is located in another side chamber of the distribution box 1. The support frame 13 is located on the back of the distribution box 1 and is used to limit and fix the distribution box 1. The support frame 13 is detachably connected to the lower side of the support leg 14. The support frame 13 is provided with a locking assembly for limiting and locking the distribution box 1. The locking assembly includes a locking block 15, a first locking plate 16 and a second locking plate 17. The locking block 15 is fixedly connected to the back of the distribution box 1. The first locking plate 16 and the second locking plate 17 are symmetrically hinged on the support frame 13 and limit and lock the locking block 15.

[0022] The design of the locking assembly precisely restricts the position of the distribution box 1 equipped with locking blocks 15. During installation, the distribution box 1 is lifted and positioned by the lifting plate 24 and the first cylinder 28. The limiting plate 23 pushes the lifting plate 24 upward, causing the distribution box 1 to move synchronously. As the distribution box 1 moves, the first locking plates 16 and the second locking plates 17 on both sides are pushed upward by the locking blocks 15 and flipped to the direction of the locking blocks 15, ultimately achieving a tight lock-in and ensuring that the distribution box 1 is firmly fixed in the predetermined position, preventing displacement or loosening. This ensures the high stability and precision of the distribution box 1 during lifting and installation. Furthermore, the effective cooperation between the locking blocks 15 and the first locking plates 16 and the second locking plates 17 enhances the safety and stability of the distribution box 1. In addition, the structure simplifies the installation process, improves efficiency, and reduces the complexity of manual operation.

[0023] Reference Figures 1 to 6 The positioning assembly also includes a positioning plate 21, a limiting plate 23, a linkage plate 27, and a reset assembly. The positioning plate 21 is fixedly connected to the side of the support frame 13 facing the distribution box 1. Two positioning posts 22 are fixedly connected to the positioning plate 21. Each positioning post 22 is used to limit the adjacent first positioning plate 16 or second positioning plate 17. The limiting plate 23 is slidably connected to the lower side of the support frame 13. The lifting plate 24 abuts against the limiting plate 23 and is slidably connected to the side of the support frame 13. The lifting groove 25 is opened on the lifting plate 24. The lifting block 26 is fixedly connected to the limiting plate 23 and abuts against the inner wall of the lifting groove 25. The upper side of the lifting block 26 is inclined. The linkage plate 27 is hinged to the limiting plate 23. The first cylinder 28 is set on the support frame 13. The telescopic column of the first cylinder 28 is hinged to the other end of the linkage plate 27. The reset assembly is set on the positioning plate 21.

[0024] Through the design of the clamping assembly, the distribution box body 1 with the clamping block 15 can be accurately positioned. When the distribution box body 1 is installed on the lifting plate 24, the first air cylinder 28 will start, completing the lifting and positioning of the distribution box body 1. At this time, through the sliding of the limiting plate 23, the lifting plate 24 is gradually moved upward. With the lifting of the lifting plate 24, the distribution box body 1 also moves, thereby synchronously pushing the first clamping plate 16 and the second clamping plate 17 on both sides in contact with the outer side of the clamping block 15 upward.

[0025] In this process, the first clamping plate 16 and the second clamping plate 17 will flip along the rising of the clamping block 15 towards the clamping block 15. This flipping makes the first clamping plate 16 and the second clamping plate 17 on both sides eventually complete the close clamping with the clamping block 15, thereby ensuring that the distribution box body 1 can be stably positioned and avoiding the phenomenon of deviation or loosening.

[0026] This design ensures the stability and accuracy of the distribution box body 1 during lifting and installation, and through the effective cooperation of the clamping block 15 and the first clamping plate 16 and the second clamping plate 17, it guarantees the fixation and safe operation of the distribution box body 1. At the same time, this structure also makes the installation of the distribution box body more efficient, reducing the complexity of manual operation.

[0027] The reset assembly makes the transfer of the distribution box body 1 more flexible and efficient. The separation of the distribution box body 1 from the clamping assembly and its subsequent transfer can greatly improve the automation level of the production line, enhance the work efficiency of the operators, and improve the safety of the production site.

[0028] Referring to Figures 2 to 4 The plurality of guide wheels 241 are rotationally connected to the lifting plate 24.

[0029] Through the plurality of guide wheels 241, the movement of the distribution box body 1 becomes smoother and more stable. The specific operation steps are that manual or mechanical equipment connects the side of the distribution box body 1 with the side of the guide wheel 241, uses the contact point as a lever fulcrum, and through the rotation of the guide wheel 241, the distribution box body 1 can be moved stably under the guidance of the guide wheel. In this way, not only the stability during movement is improved, but also the adjustment of the distribution box body 1 becomes more convenient.

[0030] In addition, after the distribution box body 1 is moved to the lifting plate 24, manual adjustment of the relative position between the distribution box body 1 and the lifting plate 24 can be more easily and accurately. In this way, the handling operation is more easy and efficient, and the labor intensity is reduced. The design of the guide wheel 241 makes the positioning operation of the distribution box body 1 more convenient, thereby improving the overall operation efficiency and the comfort of the working environment.

[0031] Referring to Figure 2The air cushion 242 is fixedly connected to the lifting plate 24.

[0032] Through the air cushion 242, the height difference between the protruding surface of the guide wheel 241 and the upper surface of the lifting plate 24 can be effectively offset, ensuring that the distribution box body 1 is stably placed on the lifting plate 24. The air cushion 242 not only balances these height differences, but also further optimizes the handling process by adjusting the amount of gas injection.

[0033] Specifically, when the distribution box body 1 needs to be removed from the support frame 13, after the clamping assembly is separated from the clamping block 15 at the rear side of the distribution box body 1 by injecting more gas, the air cushion 242 can lift the distribution box body 1 away from the support frame 13, thereby achieving easier handling. This improves handling effectiveness and efficiency, reduces manual labor intensity, and makes mechanical equipment more smooth during operation.

[0034] In addition, in addition to the air cushion 242, other substitutes with similar material properties can also be selected to further optimize the operation effect during installation of the distribution box body 1. Through such substitute materials, the impact force of the lower side of the distribution box body 1 on the lifting plate 24 can be effectively reduced, avoiding damage to the lifting plate surface, thereby improving the surface quality, reducing wear and tear, and prolonging the service life of the equipment.

[0035] In summary, the design of the air cushion 242 improves the installation and handling process of the distribution box body 1, and the selection of other substitute materials not only enhances the stability of the operation, but also improves the durability and maintenance cost of the equipment.

[0036] Embodiment 2

[0037] This embodiment improves the positioning effect of the first clamping plate 16 and the second clamping plate 17 based on Embodiment 1; Referring to Figures 3 to 6 The positioning members 29 are detachably fixedly connected to the first clamping plate 16 and the second clamping plate 17, preferably through bolt and nut connection. Two positioning members 29 are detachably fixedly connected to the first clamping plate 16 and the second clamping plate 17, respectively. The positioning member 29 is used to improve the limiting effect of the first clamping plate 16 and the second clamping plate 17 on the peripheral slot of the clamping block 15.

[0038] After the first clamping plate 16 and the second clamping plate 17 on both sides are flipped and embedded in the clamping block 15, the limiting effect on the distribution box body 1 can be effectively achieved. This design ensures that the distribution box body 1 can be firmly maintained at the predetermined position when fixed with the clamping block 15, preventing deviation and thus ensuring the working stability of the distribution box body 1.

[0039] On this basis, by increasing the positioning member 29, the limiting effect on the clamping block 15 is further enhanced. The positioning member 29 not only accurately fixes the position of the distribution box body 1, but also effectively limits the relative position height. In this way, the action of the positioning member 29 supplements the restriction of the clamping block 15, further improving the installation stability of the distribution box body 1, making the distribution box body 1 more reliable in long-term use.

[0040] In summary, the cooperation of the first clamping plate 16, the second clamping plate 17 and the clamping block 15, plus the auxiliary limiting design of the positioning member 29, forms a multiple fixing and limiting effect, significantly improves the installation stability of the distribution box body 1, and ensures its safe and efficient operation in use.

[0041] Referring to Figures 3 to 6 The rib 291 is provided on the positioning member 29.

[0042] Through the design of the rib 291, when the first clamping plate 16 and the second clamping plate 17 on both sides abut against the lower side of the clamping block 15, the limiting effect of the clamping block 15 can be effectively guaranteed, and the height position of the distribution box body 1 can be fixed. The setting of the rib 291 reduces the contact area between the positioning member 29 and the clamping block 15, thereby improving the stability of the clamping and reducing the friction.

[0043] The resistance generated by friction when clamping is reduced, so that the first clamping plate 16 and the second clamping plate 17 on both sides can be separated from the clamping block 15 more easily and stably when needed. During long-term use, the problem of adhesion between the clamping plate and the clamping block caused by dust or oil is avoided, and the phenomenon that the two clamping plates are difficult to move out of the outer slot of the clamping block 15 is prevented.

[0044] Therefore, the design of the rib 291 not only improves the stable clamping effect between the positioning member 29 and the clamping block 15, but also effectively avoids the obstacles that may occur during long-term use, ensuring smooth operation and long-term stable operation of the equipment.

[0045] Referring to Figure 6 The two limiting strips 210 for improving the limiting effect on the side edge of the clamping block 15 are respectively arranged on the first clamping plate 16 and the second clamping plate 17 towards the support frame 13.

[0046] By turning the first clamping plate 16 and the second clamping plate 17 on both sides towards the clamping block 15, and clamping the first clamping plate 16 and the second clamping plate 17 into the slot on the outer side of the clamping block 15, the distribution box body 1 can be effectively fixed to prevent it from deviating during use, thereby ensuring the stability and working accuracy of the distribution box body 1. This clamping method provides a strong limiting effect, so that the distribution box body 1 can be firmly maintained at the predetermined position.

[0047] In addition, the setting of the limiting strip 210 further enhances the fixing effect. The limiting strip 210 enhances the contact force between the first and second clamping plates 16 and 17 and the clamping block 15 by increasing the contact area with the side edge of the clamping block 15, thereby improving the limiting effect. This design makes the distribution box body 1 more stable and less likely to move or deviate.

[0048] Regarding the material of the limiting strip 210, a material with a surface having a pattern and a certain ductility, such as rubber, is preferred. The rubber material can effectively adhere to the clamping block 15, providing better friction and enhancing the fixing effect. At the same time, the ductility of the rubber material can effectively buffer part of the force transmitted by the clamping block 15, reducing the impact of vibration and impact on the distribution box body 1 and improving the stability of the overall system.

[0049] In summary, through the design of the limiting strip 210, the fixing of the distribution box body 1 is more secure, and the damage to the equipment caused by external impact is reduced, ensuring the long-term stable operation of the equipment.

[0050] Referring to Figures 2 to 3 , the reset assembly includes a driving plate 31 and two positioning discs 32. The driving plate 31 is slidingly connected to the side of the positioning plate 21 away from the distribution box body 1, each positioning disc 32 is slidingly connected to the positioning plate 21 and fixedly connected to the driving plate 31, and a second air cylinder 33 for driving the sliding of the driving plate 31 is arranged on one side of the driving plate 31.

[0051] When the distribution box body 1 needs to be removed from the support frame 13 or needs to be transferred, the second air cylinder 33 drives the driving plate 31 to move, and then the two positioning discs 32 work on the upper side bending surface of the adjacent first or second clamping plate 16 or 17, while the lower lifting plate 24 moves downward, causing the first and second clamping plates 16 and 17 on both sides to flip to the sides, and finally the first and second clamping plates 16 and 17 on both sides are separated from the clamping block 15, so that the distribution box body 1 is separated from the clamping assembly, and then the distribution box body 1 or other transfer equipment, such as a forklift, can be manually supported to transfer the distribution box body 1.

[0052] Not only does it improve the convenience of operation, but also prolongs the service life of related mechanical parts. The pneumatic system replaces the traditional mechanical operation mode, reducing mechanical wear and failure rate, and avoiding damage or delay of the distribution box body 1 caused by improper manual operation. Through precise control, the operation process is more stable and reliable.

[0053] Make the transfer of distribution box 1 more flexible and efficient. The separation of the distribution box 1 and the subsequent transfer of the clamping assembly can improve the degree of automation of the production line to a greater extent, enhance the work efficiency of the operator, and improve the safety of the production site.
