Description

Technical Field

[0001] This invention relates to a multi-protection mobile power distribution box. Background Technology

[0002] With the continuous development of power equipment and power distribution systems, mobile distribution boxes are increasingly widely used in various power facilities. As a key power distribution device, it is widely used in various temporary or mobile power systems, offering advantages such as convenience and flexibility. Traditional mobile distribution boxes typically employ a simple structural design, mainly consisting of a box frame, distribution sockets, and a simple support frame. While these traditional designs can meet basic usage requirements to a certain extent, they still have some obvious defects and shortcomings, especially in terms of structural safety, stability, and protective performance.

[0003] First, existing mobile distribution boxes typically lack effective structural stability. While some distribution boxes feature frame structures, most are installed and secured using relatively simple methods. The panel structure is prone to loosening or deformation due to external vibrations or impacts, affecting the safety and stability of the equipment. Due to insecure securing, the equipment is susceptible to displacement or damage during use, resulting in unnecessary maintenance and replacement costs for users.

[0004] Secondly, in existing technologies, most distribution boxes have relatively weak protective performance. Distribution boxes are usually designed simply and lack sufficient structural reinforcement, making them susceptible to external environmental factors (such as humidity, high temperature, or strong vibration), which can lead to damage to electrical components or short circuits. In addition, due to the inadequate locking design of distribution boxes, various components of the equipment may loosen when subjected to external impacts, increasing safety hazards.

[0005] Furthermore, traditional mobile distribution boxes lack convenience in installation and disassembly. Their internal structure is cumbersome and their fixing methods are limited, requiring lengthy disassembly and reassembly processes to install or replace certain internal components. Especially in environments requiring frequent adjustments and maintenance, this complexity often impacts efficiency and increases workload and time costs for staff.

[0006] Finally, most existing distribution box designs do not adequately consider the mobility of the equipment. Although some distribution boxes are equipped with pulley systems, these are usually not sufficiently optimized, which may result in the distribution box not moving smoothly enough. Furthermore, after prolonged use, the pulleys may wear out or malfunction, thus affecting the overall performance and user experience of the distribution box. Summary of the Invention

[0007] The purpose of this invention is to provide a multi-protection mobile distribution box, which improves the overall performance of the distribution box through a multi-structure design and solves the shortcomings of traditional distribution boxes in terms of protection, stability and operability.

[0008] The technical solution adopted by this invention to solve its technical problem is:

[0009] A multi-protection mobile distribution box includes a box frame, mounting slots within the box frame, a frame structure on the mounting slots within the box frame, a panel structure mounted on the frame structure, a distribution socket mounted on the panel structure, a bottom cover with casters on one side of the box frame, and a top cover on the other side of the box frame. The frame structure is an inwardly protruding annular latch with mounting holes on both sides and the inward side. The panel structure has several locking holes that mate with the mounting holes, and each mounting hole is equipped with at least two locking holes. The panel structure is composed of at least one panel, and the panels are arranged closely together.

[0010] Preferably, the outer side of the box frame is provided with a buckle groove, and a buckle head for fixing and limiting the bottom cover and top cover of the box frame is installed in the buckle groove.

[0011] Preferably, the bottom cover and top cover of the box frame are provided with a buckle slot that matches the buckle slot, and a buckle seat that matches the buckle head is installed in the buckle slot.

[0012] Preferably, the outer side of the box frame is also provided with a handle groove, and a handle is provided in the handle groove. The handle is inserted into the handle groove and forms a rotational engagement with the handle groove.

[0013] Preferably, the corner of the box frame is provided with a vertical support groove, and a vertical support foot is provided in the vertical support groove. The vertical support foot is an arched protrusion.

[0014] Preferably, the outer side of the box frame is also provided with an inner reinforcing groove, and the inner side of the box frame is also provided with an inner reinforcing groove corresponding to the buckle groove, the card seat groove and the handle groove.

[0015] Preferably, the plate structure is provided in two sets, and a connector is provided between the two sets of plate structures. The connector is provided on the side of the plate structure, and there is more than one connector, which is fixed to the side of the plate structure by bolts.

[0016] Preferably, the top cover of the box frame is provided with wheel recesses into which pulleys on the bottom cover of the stacked box frame can be engaged. There are four sets of wheel recesses, which are respectively located at the four corners of the top cover of the box frame.

[0017] Preferably, the bottom cover of the box frame is equipped with four sets of pulleys, which correspond to the positions of the top cover of the box frame.

[0018] Preferably, the bottom cover and top cover of the box frame are provided with concave-convex mating structures on both sides, and the outer side of the box frame is also provided with an external reinforcing groove.

[0019] The beneficial effects of this invention are:

[0020] Improved structural stability: By setting up mounting slots and frame structures inside the box frame, the panel structure can be installed and fixed more stably inside the box frame, thereby improving the overall strength and durability of the distribution box; the design of an inwardly protruding annular locking frame structure, and the tight fit between the multiple locking holes and the panel structure, enhances the protective performance of the distribution box during use, avoiding damage caused by external impacts or vibrations.

[0021] The installation and disassembly of the distribution box components are made easier by the use of multiple locking holes that match the mounting holes and the close arrangement of the plate structure. This ensures that all parts are firmly connected and not easily loosened. The bottom cover of the box frame with casters improves the mobility of the distribution box, making it easier for users to move the distribution box, especially in scenarios where frequent relocation is required.

The term "and / or" as used herein includes any and all combinations of one or more of the associated listed items. Example

[0027] See Figure 1-2 As shown, a multi-protection mobile distribution box includes a box frame 1, a mounting slot 2 disposed within the box frame 1, a frame structure 3 disposed within the box frame 1 and on the mounting slot 2, a plate structure 4 mounted on the frame structure 3, a distribution socket 5 mounted on the plate structure 4, a box frame bottom cover 6 with pulleys disposed on one side of the box frame 1, and a box frame top cover 7 disposed on the other side of the box frame 1. The mounting slot 2 is an inwardly protruding annular locking protrusion 22, and mounting holes 21 are opened on its two sides and the inward side. The plate structure 4 is provided with a plurality of locking holes 41 that cooperate with the mounting holes 21, and each mounting hole 21 is matched with at least two locking holes 41. The plate structure 4 is composed of at least one plate, and the plates are closely arranged. In this solution, two plate structures 4 are used, and a base plate 43 is provided between the two plate structures 4 for connection.

[0028] By designing the mounting slots 2 and frame structure 3, the various components of the distribution box can be tightly fixed together, preventing external vibration or impact from causing the equipment to loosen or deform. The tight fit between the plate structure 4 and the mounting holes 21 greatly improves the overall stability of the equipment, thereby enhancing its safety and durability during use. The design of the frame structure 3 and plate structure 4 effectively enhances the protective performance of the distribution box, avoiding damage to the internal electrical components from external factors (such as dust, moisture, external forces, etc.). In addition, the design of the annular locking protrusion 22 makes the distribution box more tightly sealed, further improving the protective effect.

[0029] Each mounting hole 21 is equipped with at least two locking holes 41, a design that makes installation and disassembly more convenient and flexible. Users can quickly and easily install or remove the internal components of the distribution box, reducing operation time and improving work efficiency. This feature is especially important in scenarios requiring frequent adjustments or maintenance; the bottom cover of the distribution box is designed with a caster structure, making it easy for users to move the distribution box in different usage scenarios. The caster design enhances the flexibility of the distribution box, providing great convenience, especially when the distribution box needs to be moved for repositioning.

[0030] Panel structure 4 consists of at least one panel, which are closely arranged to maximize space utilization and improve the space utilization rate of the distribution box. This design allows for a more compact and neat layout of the components inside the distribution box, avoiding wasted space. Because each part is precisely designed, especially the locking and fixing parts, it can effectively reduce damage to the distribution box during transportation and use, and extend the service life of the equipment.

[0031] The outer side of the box frame 1 is provided with a buckle groove 11, and a buckle head 12 for fixing and limiting the bottom cover 6 and the top cover 7 of the box frame is installed in the buckle groove 11; the bottom cover 6 and the top cover 7 of the box frame are provided with a buckle seat groove 61 that cooperates with the buckle groove 11, and a buckle seat 62 that cooperates with the buckle head 12 is installed in the buckle seat groove 61.

[0032] The design of the snap-fit ​​slot 11 and snap-fit ​​head 12 enables the bottom cover 6 and top cover 7 of the enclosure frame to be quickly and securely installed and fixed. Using a snap-fit ​​method greatly reduces the cumbersome steps of traditional screw fixing, simplifies the installation and disassembly process, and improves work efficiency. The cooperation between the snap-fit ​​head 12 and the snap-fit ​​seat 62 ensures that the bottom and top covers are firmly fixed, avoiding loosening that may occur with traditional methods. The snap-fit ​​design provides strong fixing force, ensuring the stability of the bottom and top covers even under vibration or external impact, enhancing the safety and reliability of the distribution box.

[0033] Compared to screw fastening, the snap-fit ​​structure effectively disperses external forces, reducing the risk of screw loosening or damage due to repeated disassembly and reassembly or prolonged use. Furthermore, the snap-fit ​​structure is easier to disassemble and less likely to damage components. Compared to traditional screw fastening, the snap-fit ​​design allows for a more compact arrangement of the various components in the distribution box, saving space and reducing the need for additional fixing materials. This design makes the overall structure of the distribution box more compact and rational, improving space utilization.

[0034] Due to the cooperative design of the buckle head 12 and the buckle seat 62, the bottom cover and the top cover can be firmly closed, reducing the intrusion of external environment (such as water, dust, etc.) into the inside of the distribution box, thereby improving the protection level of the distribution box and ensuring the normal operation of the equipment in harsh environments; due to the stability and flexibility provided by the buckle structure, the various components of the distribution box can withstand more switching operations without being easily damaged, which helps to extend the overall service life of the distribution box.

[0035] The outer side of the box frame 1 is also provided with a handle groove 13, and a handle 14 is provided in the handle groove 13. The handle 14 is inserted into the handle groove 13 and forms a rotational engagement with the handle groove 13. A vertical support groove 15 is provided at the corner of the box frame 1, and a vertical support foot 16 is provided in the vertical support groove 15. The vertical support foot 16 is an arched protrusion. An outer reinforcing groove 17 is also provided on the outer side of the box frame 1.

[0036] By providing handle slots 13 and handles 14 on the outside of the box frame 1, users can easily grab the distribution box for handling, stacking, or upright work. The handle design increases the convenience of movement, especially when frequent transportation and stacking are required. The handle is located in the center, ensuring balanced overall force during handling and effectively solving the problem of uneven weight distribution, thus improving the efficiency of movement and handling. At the same time, the handle 14 has a spring hidden in the groove, saving space. Vertical support grooves 15 and vertical support feet 16 are provided at the corners of the box frame 1, providing support during normal operation and enabling the distribution box to withstand greater weight or external impacts. The vertical support feet 16 have an arched design, which can evenly distribute the weight of the distribution box, increase its overall stability, and prevent the box from tilting or being damaged due to imbalance or external forces.

[0037] The design of the handle slot 13 and the handle 14 does not take up much extra space, maintaining the compactness of the distribution box while improving the convenience of handling and operation. The vertical support feet 16 also make reasonable use of the corner space of the box, enabling the distribution box to provide higher stability and support without increasing its volume. The rotating and concealed design of the handle prevents it from being damaged by external impacts when not in use, while the arched design of the support feet effectively avoids the impact of uneven ground or external pressure on the bottom of the distribution box during long-term placement, thereby improving the service life of the distribution box.

[0038] The outer side of the box frame 1 is also provided with an inner reinforcing groove 63. The inner side of the box frame 1 is provided with an inner reinforcing groove 63 corresponding to the buckle groove 11, the card seat groove 61 and the handle groove 13. The plate structure 4 is provided in two sets, and a connector 42 is provided between the two sets of plate structures 4. The connector 42 is provided on the side of the plate structure 4, and there is more than one connector. It is fixed to the annular buckle 22 and the side of the plate structure 4 by bolts.

[0039] The inclusion of inner reinforcing grooves 63 on the outer side of the frame 1 effectively improves the overall structural strength of the enclosure, particularly preventing deformation or damage when subjected to external pressure, vibration, or impact. The design of the inner reinforcing grooves 63 in the bottom cover 6 and top cover 7 of the frame enhances the durability of the components within the frame 1, ensuring their stability during long-term use. These inner reinforcing grooves 63 are located on the inner sides of the bottom cover 6 and top cover 7, areas that typically bear significant stress and load. The addition of reinforcing ribs enhances the compressive strength and load-bearing capacity of these areas, preventing damage or deformation caused by external forces during use.

[0040] The two sets of plate structures 4 are connected by connector 42, which is located between the plate structure 4 and the annular retaining protrusion 22. This design effectively disperses and transfers external loads, making the mechanical load on the box more even when bearing weight, reducing local stress concentration, and thus improving the overall stability and compressive strength of the box. Fixing connector 42 with bolts ensures a firm connection between the two sets of plate structures 4, while also strengthening the connection between the frame structure and the box frame, preventing loosening or structural instability due to vibration or prolonged use. The built-in hexagonal bolts in plastic provide high fixing strength, ensuring that connector 42 can work stably under any conditions.

[0041] Through the rational configuration of reinforcing ribs and plate structure 4, not only is the structural strength enhanced, but the use of materials is also optimized, avoiding unnecessary over-reinforcement and ensuring that the enclosure has high load-bearing capacity and stability without increasing excessive weight and volume. The overall reinforced design improves the durability of the enclosure, reduces damage caused by external pressure or prolonged use, and extends the product's service life. At the same time, this structural design allows the enclosure to maintain its structural integrity even in harsh working environments, adapting to various working conditions. Plate structure 4 facilitates the installation of components and also serves as a reinforcement of the frame structure.

[0042] The top cover 7 of the box frame is provided with wheel recesses 71 for the pulleys on the bottom cover 6 of the box frame to be inserted. There are four sets of wheel recesses 71, which are respectively located at the four corners of the top cover 7 of the box frame. There are also four sets of pulleys on the bottom cover 6 of the box frame, which correspond to the positions of the top cover 7 of the box frame. The inner reinforcing grooves of the top cover 7 and the bottom cover 6 of the box frame are equipped with sealing rings, which work together with the convex ring of the frame of the box body 1 to achieve the function of sealing and fastening. The front and rear of the box frame 1 are flared structures, which facilitates drainage in rainy weather and the insertion and removal of components during use.

[0043] Wheel recesses 71 are provided on the top cover 7 of the container frame, and these wheel recesses 71 correspond to the pulleys on the bottom cover, enabling stable stacking of the containers. Through the pulley locking design, the container frames 1 can be precisely aligned and locked together, ensuring that slippage or tilting does not occur during stacking, improving space utilization and stability during storage. The alignment design of the wheel recesses 71 not only ensures the stability of the container frames 1 during stacking but also reduces friction and collisions during stacking, preventing uneven stress or damage to the top or bottom of the container frames 1. The wheel recesses 71 provide a robust connection method, reducing the risk of damage due to improper stacking.

[0044] This design allows multiple boxes 1 to be stacked stably, saving handling and storage space. The wheel wells 71 facilitate easy disassembly and re-stacking of the stacked boxes 1; handling personnel only need to align the wheel wells with the pulley holes to complete the stacking, improving handling and stacking efficiency. Positioning the wheel wells 71 at the four corners evenly distributes the weight of the boxes 1, preventing excessive localized stress and enhancing the overall structural stability. The connection between the top and bottom covers not only provides additional support but also effectively bears the weight pressure that may occur during stacking.

[0045] This solution can adapt to different stacking needs, especially in scenarios where multiple boxes 1 need to be stacked for storage or transportation. The wheel well 71 design ensures reliable docking and stable support between each box 1. This design allows the box to play a greater role in various scenarios such as warehousing and transportation. Because there is a dedicated wheel well 71 on the top of the box 1, it can prevent the boxes 1 from rubbing against each other and coming into contact with internal components during stacking, reducing the accumulation of dust and stains, and facilitating daily maintenance and cleaning.

[0046] The bottom cover 6 and top cover 7 of the box frame are provided with concave-convex fitting structures 8 on both sides. These concave-convex fitting structures 8 facilitate vertical stacking, and the top is flush with the vertical support feet, making it easy for the door lock hinges to be aligned when locking. Without this protrusion, the hand needs to lift the box and exert force to unlock it. With the protrusion, the box can be placed directly on the ground and aligned to lock. The concave-convex fitting structure 8 on the box frame 1 is provided with a rope hole 81, which can be used to thread a rope to carry the box.

[0047] The above embodiments of the present invention are not intended to limit the scope of protection of the present invention. The implementation of the present invention is not limited thereto. All other modifications, substitutions or alterations made to the above structure of the present invention based on the above content of the present invention, in accordance with ordinary technical knowledge and common practice in the field, without departing from the basic technical idea of ​​the present invention, shall fall within the scope of protection of the present invention.
