Description

Technical Field

[0001] The present invention belongs to the technical field of distribution boxes, and more specifically, particularly relates to a wall-mounted distribution box and an installation method thereof. Background Art

[0002] The distribution box is an electrical equipment with the characteristics of small size, easy installation, special technical performance, fixed position, unique configuration function, no site restrictions, wide application, stable and reliable operation, high space utilization, small footprint and environmental protection.

[0003] However, the existing wall-mounted distribution box still has the following shortcomings when in use: 1. The installation of existing wall-mounted distribution boxes requires precise measurement and positioning, which is time-consuming and laborious. Moreover, the weight after installation is often not evenly distributed on the wall, which may cause excessive stress on the wall. Especially during long-term use, the wall may be damaged as the distribution box shakes slightly. At the same time, the risk of damage to the distribution box itself due to uneven stress is also increased. Moreover, most of the mounting brackets are exposed to the outside, which is prone to rust after long-term use. 2. The existing wall-mounted distribution boxes are relatively passive in terms of heat dissipation and protection functions, and cannot be flexibly switched according to actual environmental changes and usage requirements. For example, when heat dissipation is required in a high-temperature environment, the heat dissipation channel cannot be constructed in a timely and effective manner, resulting in internal heat accumulation, degradation of electrical component performance, and malfunctions. When encountering rainy weather or other scenes that require protection, the equipment cannot be protected, and rainwater can easily penetrate into the box through the heat dissipation grooves and damage electrical components.

[0015] Compared with the prior art, the present invention has the following beneficial effects: In the present invention, by designing the equipment as an adjustable installation mode, during installation, it is only necessary to slide and adjust the spacing according to the position of the expansion bolts, without complicated measurement and positioning, which greatly shortens the installation time and improves the work efficiency. In addition, two sets of straightening blocks can keep the two large hanging pieces in a vertical position, and two sets of straightening strips can keep the two small hanging pieces in a horizontal position. This multi-component structure design that cooperates with each other can more evenly disperse the weight of the distribution box body, enhance the overall stability, and reduce the safety hazards caused by shaking or displacement. In the present invention, a distribution box body, a first heat dissipation groove, a first slide groove, a limit strip, a first spring, a connecting rod, a slide bar, a slot, a protective plate and a second heat dissipation groove are provided. When the two connecting rods move, the two slide bars will be driven to slide inside the two first slide grooves, and the connecting rod located in the middle will form a shielding protection. When the slide bar slides to the end, the limit strip can be loosened to reset it and slide it into the slot to limit the slide bar. At the same time, the first spring will be compressed. At this time, the connecting rod will synchronously drive the protective plate to slide. When the protective plate slides, the second heat dissipation groove will overlap with the first heat dissipation groove. At this time, the second heat dissipation groove and the first heat dissipation groove will form a heat dissipation channel, and the air inside the distribution box body will form a circulation. Through the ingenious structural design, when the equipment needs to dissipate heat at high temperature outdoors, the equipment can quickly build an effective heat dissipation channel to circulate the air inside the distribution box body, accelerate the heat dissipation, effectively reduce the internal temperature of the equipment, ensure the stable operation of the equipment in a high temperature environment, and avoid performance degradation or failure due to overheating. In the present invention, by providing a distribution box body, a first heat dissipation groove, a limit strip, a first spring, a connecting rod, a drainage plate, a silicone strip, a protective plate, a wire trough and a heat dissipation cover, when it rains, the lock of the limit strip is first released, and then the first spring will restore the deformation to drive the connecting rods and the protective plate at both ends to reset, and the second heat dissipation groove on the protective plate will be misaligned with the first heat dissipation groove, completing the closure of the first heat dissipation groove and the second heat dissipation groove, preventing rainwater from entering the distribution box body from the first heat dissipation groove. At this time, the distribution box body will dissipate heat through the wire trough, and the heat will be dissipated downward through the heat dissipation cover. At the same time, the silicone strip will fit the wall and be squeezed. At this time, the connecting rod, the drainage plate and the protective plate will be combined to form a closed structure, and the rainwater will be drained and discharged through the drainage plate, so that the internal installation structure will not be rusted in contact with rainwater, which greatly extends the service life of the equipment and ensures that the equipment can operate stably in a humid environment; In the present invention, by providing a fixing column, a first spring, a connecting rod, a drainage plate and a silicone strip, when the wall surface is uneven, since the multiple connecting rods are separate individuals, the multiple connecting rods will be adaptively adjusted accordingly. This adaptive sealing structure makes the device not only suitable for conventional installation environments, but also can play a good waterproof and protective effect under some complex wall conditions, thereby expanding the scope of application of the device; In the present invention, by providing a distribution box body, a protective plate, a fixing bolt, a dovetail protection strip and a corner protection strip, the corner protection strip can be moved outwards in the two protective plates after installation, and the corner protection strip will drive the dovetail protection strip to slide outwards inside the dovetail groove, and then the fixing bolt can be rotated on the protective plate to position the dovetail protection strip, and the outer shell and corners of the distribution box body are protected by the combination of the dovetail protection strip and the corner protection strip. The corner protection strip cooperates with the dovetail protection strip and the fixing bolt, so that when not in use, the dovetail protection strip and the corner protection strip can be stored without affecting the appearance and normal use of the equipment; when protection is needed, they can be quickly unfolded and fixed, taking into account the beauty and protection requirements of the equipment; In the present invention, a sliding rod, a connecting strip, a slider, a wire tube and a second spring are provided. When the sliding rod moves, the connecting strip will be driven to move accordingly. At this time, the wire tube will also move accordingly. At the same time, the second spring will be compressed. At this time, the connecting wire can be placed inside the wire tube. Then, the sliding rod is released. The second spring will drive the wire tube to reset. The connecting wire is protected and stored by the wire tube. During protection, the slider can be slid inside the connecting strip to adjust the storage position of the connecting wire. The device can prevent the connecting wire from being directly exposed to the external environment, reduce damage to the connecting wire caused by external factors such as collision, friction and pulling, extend the service life of the connecting wire, and improve the stability and reliability of the device.

[0020] In order to overcome the shortcomings of the prior art, the present invention also provides a method for installing a wall-mounted distribution box, comprising the following steps: S1: During installation, drill holes at a suitable distance at the wall installation location, then pre-install expansion bolts at the drilling locations and tighten them; S2: Then, two large hanging pieces 45 are vertically sleeved on the two screw rods 43 located above, and two hexagonal nuts 44 are threadedly installed on the two screw rods 43. Then, two adjustment blocks 42 are slid inside the mounting frame 41 according to the positions of the expansion bolts, so that the spacing between the two adjustment blocks 42 is equal to the spacing between the two expansion bolts. At this time, the hexagonal nuts 44 can be rotated on the screw rods 43 to complete the position fixing. S3: Then, two small hanging pieces 48 are placed on the two screw rods 43 located at the bottom, and then the positions of the two small hanging pieces 48 are adjusted according to the positions of the expansion bolts, and after adjustment, they are fixed by the hexagonal nuts 44; S4: After the fixing is completed, the distribution box body 11 is hung on the wall, the large hanging piece 45 and the small hanging piece 48 are put on the expansion bolts, and the large hanging piece 45 and the small hanging piece 48 are locked with nuts to complete the installation of the distribution box body 11.

[0021] Working principle: The first step is to drill holes at a suitable distance at the wall installation position during installation, then pre-install expansion bolts at the drilling positions and tighten them, then vertically sleeve the two large hanging pieces 45 on the two screw rods 43 located above, and then thread the two hexagonal nuts 44 on the two screw rods 43. At this time, the two large hanging pieces 45 can be kept in a vertical position under the action of the two sets of straightening blocks 46, and then slide the two adjustment blocks 42 inside the mounting frame 41 according to the position of the expansion bolts, so that the spacing between the two adjustment blocks 42 is equal to the spacing between the two expansion bolts. At this time, the hexagonal nuts 44 can be rotated on the screw rods 43 to complete the position fixing, and then sleeve the two small hanging pieces 48 on the two screw rods 43 located below. The two small hanging pieces 48 can be kept in a horizontal position under the action of the two sets of straightening strips 47, and then adjust according to the position of the expansion bolts. The positions of the two small hanging pieces 48 are adjusted and fixed by the hexagonal nuts 44; after the fixing is completed, the distribution box body 11 is hung on the wall, the large hanging piece 45 and the small hanging piece 48 are put on the expansion bolts, and the large hanging piece 45 and the small hanging piece 48 are locked with nuts to complete the installation of the distribution box body 11. By designing the equipment as an adjustable installation method, during installation, it is only necessary to slide and adjust the spacing according to the position of the expansion bolts, without tedious measurement and positioning, which greatly shortens the installation time and improves work efficiency. In addition, the two large hanging pieces 45 can be kept in a vertical position by two sets of straightening blocks 46, and the two small hanging pieces 48 can be kept in a horizontal position by two sets of straightening strips 47. This structural design with multiple components cooperating with each other can more evenly disperse the weight of the distribution box body 11, enhance the overall stability, and reduce safety hazards caused by shaking or displacement. In the second step, when the device is placed outdoors on a sunny day and the temperature is high and heat needs to be dissipated, the limit strip 19 can be flipped outward inside the second inner groove 18, and then the connecting rods 23 at both ends can be slid into the top plate 14. The movement of the two connecting rods 23 will drive the two slide bars 25 to slide inside the two first slide grooves 17, and the connecting rod 23 in the middle will form a shielding protection. When the slide bar 25 slides to the end, the limit strip 19 can be loosened to reset it and slide it into the card slot 26 to limit the slide bar 25. At the same time, the first spring 22 will be compressed, and the connecting rod 23 will be simultaneously The second heat dissipation slot 32 will overlap with the first heat dissipation slot 13 after the protective plate 31 slides. At this time, the second heat dissipation slot 32 and the first heat dissipation slot 13 will form a heat dissipation channel, and the air inside the distribution box body 11 will circulate. The device is cleverly designed to quickly build an effective heat dissipation channel when the device needs to dissipate heat outdoors at high temperatures, so that the air circulates inside the distribution box body 11, accelerates heat dissipation, effectively reduces the internal temperature of the device, and ensures that the device can operate stably in a high temperature environment to avoid performance degradation or failure due to overheating. The third step is to release the lock of the limit strip 19 when it rains, and then the first spring 22 will restore its deformation to drive the connecting rod 23 and the protective plate 31 at both ends to reset, and the second heat dissipation slot 32 on the protective plate 31 will be misaligned with the first heat dissipation slot 13, completing the closure of the first heat dissipation slot 13 and the second heat dissipation slot 32, preventing rainwater from entering the distribution box body 11 from the first heat dissipation slot 13. At this time, the distribution box body 11 will dissipate heat through the wire trough 49, and the heat will dissipate downward through the heat dissipation cover 57. At the same time, the silicone strip 27 will be pressed against the wall. At this time, the connecting rod 23, the drain plate 24 and the protective plate 31 will be combined to form a closed structure, and the rainwater will be drained through the drain plate 24, so that the internal installation structure will not rust when in contact with rainwater, which greatly extends the service life of the equipment and ensures that the equipment can operate stably in a humid environment; Step 4: When the wall surface is uneven, since the multiple connecting rods 23 are separate entities, the multiple connecting rods 23 will be adjusted adaptively accordingly. This adaptive sealing structure makes the device not only suitable for conventional installation environments, but also can play a good waterproof and protective effect under some complex wall conditions, thereby expanding the scope of application of the device; The fifth step is to move the corner protection strip 39 outward in the two protection plates 31 after installation. At this time, the corner protection strip 39 will drive the dovetail protection strip 36 to slide outward inside the dovetail groove 33. Then, the fixing bolt 35 can be rotated on the protection plate 31 to position the dovetail protection strip 36. At this time, the shell and corners of the distribution box body 11 are protected by the combination of the dovetail protection strip 36 and the corner protection strip 39. The corner protection strip 39 cooperates with the dovetail protection strip 36 and the fixing bolt 35. When not in use, the dovetail protection strip 36 and the corner protection strip 39 can be stored without affecting the appearance and normal use of the equipment. When protection is needed, they can be quickly unfolded and fixed, taking into account the beauty and protection needs of the equipment. The sixth step is that during installation, the connecting wires inside the distribution box body 11 can pass through the wire groove 49 and the heat dissipation cover 57, and then the slide bar 52 is pulled outward. The movement of the slide bar 52 will drive the connecting strip 53 to move accordingly, and the wire tube 55 will also move accordingly. At the same time, the second spring 56 will be compressed. At this time, the connecting wires can be placed inside the wire tube 55, and then the slide bar 52 is released. The second spring 56 will drive the wire tube 55 to reset. The connecting wires are protected and stored by the wire tube 55. During protection, the slider 54 can also be slid inside the connecting strip 53 to adjust the storage position of the connecting wires. The device can prevent the connecting wires from being directly exposed to the external environment, reduce the damage to the connecting wires caused by external factors such as collision, friction, and pulling, extend the service life of the connecting wires, and improve the stability and reliability of the equipment.
