Technical Field

[0001] This utility model relates to the field of distribution box technology, and in particular to a distribution box with stable transportation. Background Technology

[0002] As a key electrical control and protection device in a power system, the distribution box's structural design must meet core requirements such as protection of internal components, operational safety, and ease of maintenance. Depending on the application scenario, distribution boxes are typically classified into three categories based on size and capacity: small, medium, and large. Medium and large boxes are widely used in commercial buildings, small and medium-sized factories, large industrial facilities, and data centers.

[0003] Existing distribution box enclosures typically use support plates for functional partitioning, with these plates fixed to the side walls using fasteners. This structure requires extensive tightening during installation, reducing assembly efficiency. Furthermore, during transportation, vehicle vibrations or unexpected impacts can cause relative displacement of the support plates, leading to mechanical stress on the mounted electrical components. This can result in loose electrical connections and poor contact, affecting equipment stability, shortening component lifespan, and creating potential safety hazards. In addition, traditional fixing methods place high demands on the overall structural strength of the enclosure, and repeated disassembly and reassembly of fasteners are required for later maintenance or component replacement, further increasing operational complexity. Therefore, it is necessary to improve the design of the internal support structure of the distribution box to address these technical shortcomings. Summary of the Invention

[0004] The purpose of this utility model is to overcome the shortcomings of the above-mentioned distribution box design and to provide a product with reliable connection, improved transmission efficiency, and anti-slip properties.

[0005] To solve the above problems, the present invention adopts the following technical solution.

[0033] The technical solution of this utility model will be clearly and completely described below with reference to the embodiments. Obviously, the described embodiments are only some embodiments of this utility model, not all embodiments. Based on the embodiments of this utility model, all other embodiments obtained by those skilled in the art without creative effort are within the protection scope of this utility model.

[0034] In the description of this utility model, it should be understood that the terms "upper", "lower", "left", "right", etc., indicate the orientation or positional relationship based on the orientation or positional relationship shown in the accompanying drawings. They are only for the convenience of describing this utility model and simplifying the description, and do not indicate or imply that the device or element referred to must have a specific orientation, or be constructed and operated in a specific orientation. Therefore, they should not be construed as limitations on this utility model.

[0035] In this embodiment of the utility model, "and / or" is merely a description of the relationship between related objects, indicating that three relationships can exist. For example, A and / or B can represent three situations: A exists alone, A and B exist simultaneously, and B exists alone. Additionally, the character " / " in this document generally indicates that the preceding and following related objects have an "or" relationship.

[0036] Reference example Figures 1 to 5 A stable distribution box includes a box body 1 and a support frame 2. The box body 1 has at least one guide groove 11 on each side, and the guide groove 11 has several equally spaced first blind holes 12 from top to bottom. The support frame 2 has retractable fixing components 3 on both sides, which are inserted into any one of the first blind holes 12 to connect and fix the support frame 2 to the box body 1. The support frame 2 has an operating component 4 connected to the fixing component 3, used to disconnect the support frame 2 from the box body 1 and keep the fixing component 3 in a disengaged state. The support frame 2 has a liftable support plate 5, and multiple buffer springs 53 are provided between the support plate 5 and the support frame 2.

[0037] The retractable fixing component 3 allows the support frame 2 to be locked at any position within the vertical space of the housing 1, enabling rapid installation. The operating component 4 drives the fixing component 3 to disengage from the first blind hole 12, releasing the constraint on the support frame 2 and enabling it to be freely adjusted vertically. It should be noted that when adjusting the spatial position of the support frame 2, it is necessary to ensure that no electrical components are installed on the bearing plate 5 to facilitate the adjustment of the spatial position of the support frame 2. The operating mechanism integrates a holding mechanism to keep the fixing component 3 in the unlocked state, allowing users to complete height adjustment without tools, improving operational convenience. The above design simplifies the disassembly and assembly process and improves on-site maintenance efficiency.

[0038] It is worth mentioning that the corner of the support frame 2 is provided with a limiting guide rod 6, which passes through the bearing plate 5. The outer wall of the limiting guide rod 6 is provided with a shock-absorbing sleeve 7. The end of the limiting guide rod 6 is provided with an insulating pad 8 and a flat washer 9 in sequence. The flat washer 9 is provided with a fastening screw 10 and is threaded to the limiting guide rod 6. The limiting guide rod 6 controls the upward stroke of the bearing plate 5. The shock-absorbing sleeve 7 is made of rubber, which effectively suppresses irregular radial vibration, absorbs vibration energy and reduces noise generation. The insulating pad 8 is set between the flat washer 9 and the bearing plate 5 to avoid direct metal contact that may cause abnormal noise, while improving electrical insulation performance.

[0039] It is worth mentioning that the outer sides of the support frame 2 are provided with guide parts 21 and are slidably disposed in the guide groove 11. The guide parts 21 are provided with guide holes 22 for the fixed components 3 to move. The front of the support frame 2 is provided with an inner groove 23. The inner groove 23 is provided with an operating handle 24. The guide parts 21 guide the support frame 2 to rise and fall along the trajectory of the guide groove 11. The inner groove 23 is designed to hide the operating handle 24, avoiding interference with the opening of the box door. The operating handle 24 is designed to facilitate the handling of the support frame 2 and the bearing plate 5, and to assist in their precise placement into the guide groove 11.

[0040] It is worth mentioning that the support frame 2 is provided with a through groove 25, and the through groove 25 is provided with a first countersunk hole 221 corresponding to the guide hole 22. The two sides of the end face of the support frame 2 are provided with a plurality of second blind holes 26 for accommodating the buffer spring 53. The through groove 25 exposes the mounting hole 51 to the installer's field of vision. When installing electrical components, if it is necessary to use a fastening bolt, the nut and the fastening bolt can be easily connected through the through groove 25. The second blind hole 26 and the third blind hole 52 concentrate the force of the buffer spring 53.

[0041] It is worth mentioning that the support plate 5 is provided with several equally spaced mounting holes 51, and the support plate 5 is provided with a third blind hole 52 corresponding to the second blind hole 26. Electrical components are connected to the mounting holes 51 by fastener threads, so that they are installed on the support plate 5. The buffer spring 53 structure absorbs the external impact and vibration generated during transportation, reduces the vibration transmission to electrical components, reduces the risk of loose electrical connections due to mechanical stress, and ensures the reliability of electrical contact. The above design effectively suppresses the impact of vibration on the internal structure of components, extends the service life of components, and avoids fatigue damage caused by vibration. The overall structure improves the operational stability of the equipment in complex transportation environments and reduces the failure rate.

[0042] It is worth mentioning that the fixing component 3 includes a fixing rod 31 and a compression spring 32. The fixing rod 31 is provided with a threaded hole 311, and the end face of the threaded hole 311 is provided with a second countersunk hole 312. The fixing rod 31 is provided with a fourth blind hole 313 on the end face away from the second countersunk hole 312. The end face of the fixing rod 31 is provided with a stop 314, which is slidably disposed in the first countersunk hole 221. The compression spring 32 continuously applies force to the fixing rod 31, so that it keeps it in close contact with the first blind hole 12, ensuring that the connection structure is stable and reliable. The second countersunk hole 312 is designed to accommodate the head of the fastening screw 10, avoiding protrusion that affects assembly or operation. The fourth blind hole 313 provides compression stroke space for the compression spring 32, ensuring that the spring deformation is not restricted.

[0043] It is worth mentioning that the operating component 4 includes a clamping nut 41 and an operating rod 42. The clamping nut 41 is threadedly connected to the first countersunk hole 221. The clamping nut 41 has a through hole 411. The end face of the threaded rod of the clamping nut 41 is provided with a magnet 43, which magnetically attracts the stop part 314. The operating rod 42 passes through the through hole 411 and is connected and fixed to the threaded hole 311 by a fastening screw 10. The operating rod 42 is linked to all the fixed rods 31 on one side of the through groove 25 to achieve synchronous driving. When the stop part 314 abuts against the magnet 43, the magnetic attraction keeps the fixed rod 31 in the released state. After pushing the operating rod 42 to overcome the magnetic attraction, the compression spring 32 releases the elastic force, driving the fixed rod 31 to extend quickly along the direction of the guide hole 22.

[0044] It is worth mentioning that the compression spring 32 is provided in the fourth blind hole 313 and acts on the clamping nut 41, so that the stop 314 abuts against the end face of the first countersunk hole 221, and the stop 314 limits the stroke of the fixing rod 31 extending out of the guide hole 22.

[0045] The above description, in conjunction with specific embodiments, provides a further detailed explanation of the present utility model. It should not be construed that the specific implementation of the present utility model is limited to these descriptions. For those skilled in the art, several simple deductions or substitutions can be made without departing from the concept of the present utility model, and all such deductions or substitutions should be considered to fall within the scope of protection defined by the claims submitted by the present utility model.
