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] A distribution box is an electrical equipment, which has the characteristics of small volume, simple installation, special technical performance, fixed position, unique configuration function, not restricted by the site, relatively common application, stable and reliable operation, high space utilization rate, less land occupation and environmental protection effect.

[0003] However, the existing wall-mounted distribution boxes still have the following deficiencies when in use:

[0004] 1. The installation of the existing wall-mounted distribution box requires precise measurement and positioning, which is time-consuming and laborious, and the weight after installation often cannot be evenly distributed on the wall surface. This may cause excessive local stress on the wall surface. Especially during long-term use, with the slight shaking of the distribution box, the wall surface may be damaged, and at the same time, it also increases the risk of damage to the distribution box itself due to uneven stress. Moreover, most of the installation brackets are exposed outside and are prone to rust after long-term use;

[0005] 2. The existing wall-mounted distribution boxes are relatively passive in heat dissipation and protection functions and cannot be flexibly switched according to the actual environmental changes and usage requirements. For example, when heat dissipation is required in a high-temperature environment, a heat dissipation channel cannot be effectively constructed in time, resulting in the accumulation of internal heat, the decline of the performance of electrical components, and the occurrence of faults. And when encountering rainy weather or other scenarios that require protection, the equipment cannot be protected, and rainwater easily seeps into the box through the heat dissipation slots, damaging the electrical components. Summary of the Invention

[0006] In order to solve the above technical problems, the present invention provides a wall-mounted distribution box and an installation method thereof to solve the above problems.

[0007] A wall-mounted distribution box includes a distribution box body. A box door is hinged to the front surface of the distribution box body. First heat dissipation slots are opened on both side walls of the distribution box body. A top plate is fixedly installed at the upper end of the distribution box body.

[0010] Preferably, dovetail grooves are formed on the opposite ends of the two protective plates. Accommodating grooves are formed on the side walls of the two protective plates. A dovetail protective strip is slidably installed inside each dovetail groove.

[0011] Preferably, corner protective strips are fixedly installed inside each group of dovetail protective strips. The two corner protective strips are arranged inside the two accommodating grooves.

[0012] Preferably, mounting frames are symmetrically and fixedly installed on the back surface of the distribution box body. Adjusting blocks are symmetrically and slidably installed inside the two mounting frames. Screws are fixedly installed on the two groups of adjusting blocks. Hexagonal nuts are threadedly installed on the two groups of screws.

[0013] Preferably, large hanging pieces are sleeved on the two screws located above. Straightening blocks are symmetrically and fixedly installed on the two adjusting blocks located above. Straightening strips are symmetrically and fixedly installed on the mounting frame located below. Small hanging pieces are sleeved on the two screws located below. A wire groove is formed on the back surface of the distribution box body.

[0014] Preferably, a column groove is formed on the mounting frame located below. A sliding rod is slidably installed inside the column groove. A connecting strip is welded inside the inner wall of the mounting frame located below.

[0015] Preferably, sliders are slidably installed at equal intervals inside the connecting strip. A wire pipe is fixedly installed on the side wall of each slider.

[0016] Preferably, second springs are symmetrically sleeved on the sliding rod, and two ends of the two second springs are fixedly connected to the mounting frame and the connecting strip respectively. A heat dissipation cover is fixedly mounted on the back of the distribution box body, and the heat dissipation cover opens downward and faces the wire groove.

[0017] In order to overcome the deficiencies of the prior art, the present invention also provides an installation method for a wall-mounted distribution box, including the following steps:

[0018] S1: When installing, drill holes at appropriate distances at the installation position on the wall, and then pre-install expansion bolts at the drilled positions and tighten them.

[0019] S2: Then vertically sleeve two large hanging pieces on the two upper screws, thread two hexagonal nuts onto the two screws, and then slide two adjusting blocks inside the mounting frame according to the positions of the expansion bolts so that the distance between the two adjusting blocks is equal to the distance between the two expansion bolts. At this time, the hexagonal nuts can be rotated on the screws to complete the position fixing.

[0020] S3: Then sleeve two small hanging pieces on the two lower screws, and then adjust the positions of the two small hanging pieces according to the positions of the expansion bolts. After adjustment, fix them with hexagonal nuts.

[0021] S4: After the fixing is completed, hang the distribution box body on the wall, sleeve the large hanging pieces and the small hanging pieces on the expansion bolts, and use nuts to lock the large hanging pieces and the small hanging pieces to complete the installation of the distribution box body.

[0022] Compared with the prior art, the present invention has the following beneficial effects:

[0023] In the present invention, by designing the device as an adjustable installation method, during installation, only the spacing needs to be adjusted by sliding according to the positions of the expansion bolts, without cumbersome measurement and positioning, greatly shortening the installation time and improving work efficiency. Moreover, through two groups of straightening blocks, the two large hanging pieces can be kept in a vertical position, and through two groups of straightening strips, the two small hanging pieces can be kept in a horizontal position. This structural design with the cooperation of multiple components can more evenly disperse the weight of the distribution box body, enhance the overall stability, and reduce potential safety hazards caused by shaking or displacement.

[0024] In the present invention, by providing a distribution box body, a first heat dissipation groove, a first sliding groove, a limiting strip, a first spring, a connecting rod, a sliding strip, a clamping groove, a protection plate and a second heat dissipation groove, the movement of the two connecting rods will drive the two sliding strips to slide inside the two first sliding grooves. The connecting rod located in the middle will form a shielding protection. When the sliding strip slides to the end, the limiting strip can be released to reset and slide into the clamping groove to limit the sliding strip. At the same time, the first spring will be compressed. At this time, the connecting rod will synchronously drive the protection plate to slide. When the protection 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 cycle. Through the ingenious structural design of the device, when the device needs to dissipate heat in high temperature outdoors, an effective heat dissipation channel can be quickly constructed, the air inside the distribution box body can circulate, the heat dissipation can be accelerated, the internal temperature of the device can be effectively reduced, and the stable operation of the device in a high temperature environment can be ensured, avoiding performance degradation or failure caused by overheating;

[0025] In the present invention, by providing a distribution box body, a first heat dissipation groove, a limiting strip, a first spring, a connecting rod, a drainage plate, a silica gel strip, a protection plate, a wire groove and a heat dissipation cover, when it rains, first unlock the limiting strip, and then the first spring will restore its deformation to drive the connecting rods and the protection plate at both ends to reset. The second heat dissipation groove on the protection plate will be misaligned with the first heat dissipation groove to complete the closing of the first heat dissipation groove and the second heat dissipation groove, preventing rainwater from entering the inside of the distribution box body through the first heat dissipation groove. At this time, the distribution box body will dissipate heat through the wire groove, and the heat will dissipate downward through the heat dissipation cover. At the same time, the silica gel strip will be pressed against the wall surface. At this time, the connecting rod, the drainage plate and the protection plate will form a closed structure, and the rainwater will be drained out through the drainage plate, so that the internal installation structure will not come into contact with the rainwater and rust, greatly extending the service life of the device and ensuring the stable operation of the device in a humid environment;

[0026] In the present invention, by providing fixed columns, a first spring, connecting rods, a drainage plate and a silica gel strip, when the wall surface is uneven, since the multiple connecting rods are separate individuals, the multiple connecting rods will adaptively adjust accordingly. This adaptive sealing structure enables the device to not only be applicable to a conventional installation environment, but also play a good waterproof and protective effect under some complex wall conditions, expanding the applicable range of the device;

[0027] In the present invention, by providing a distribution box body, a protective plate, fixing bolts, a dovetail protective strip and a corner protective strip, after installation, the corner protective strip can be moved outwards between the two protective plates. At this time, the corner protective strip will drive the dovetail protective strip to slide outwards inside the dovetail groove. Then, the fixing bolts can be rotated on the protective plate to position the dovetail protective strip. At this time, the combination of the dovetail protective strip and the corner protective strip protects the shell and corners of the distribution box body. The cooperation of the corner protective strip, the dovetail protective strip and the fixing bolts allows the dovetail protective strip and the corner protective strip to be stored when not in use, without affecting the appearance and normal use of the equipment; when protection is required, they can be quickly deployed and fixed, taking into account both the aesthetics and protection requirements of the equipment;

[0028] In the present invention, by providing a sliding rod, a connecting strip, a slider, a wire tube and a second spring, the movement of the sliding rod will drive the connecting strip 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, and then the sliding rod is released. The second spring will drive the wire tube to reset, protecting and storing the connecting wire through the wire tube. And when protecting, the slider can also be slid inside the connecting strip to adjust the storage position of the connecting wire. This 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 equipment.

[0040] In order to overcome the deficiencies of the prior art, the present invention also provides an installation method for a wall-mounted distribution box, including the following steps:

[0041] S1: When installing, drill holes at appropriate distances at the installation position on the wall, and then pre-install expansion bolts at the drilling positions and tighten them;

[0042] S2: Next, vertically sleeve the two large hanging pieces 45 onto the two upper screws 43, then threadedly install the two hexagonal nuts 44 onto the two screws 43. Then, slide the two adjusting blocks 42 inside the mounting frame 41 according to the positions of the expansion bolts so that the distance between the two adjusting blocks 42 is equal to the distance between the two expansion bolts. At this time, the position can be fixed by rotating the hexagonal nuts 44 on the screws 43;

[0043] S3: Next, sleeve the two small hanging pieces 48 onto the two lower screws 43, and then adjust the positions of the two small hanging pieces 48 according to the positions of the expansion bolts. After adjustment, fix them with the hexagonal nuts 44;

[0044] S4: After the fixation is completed, hang the distribution box body 11 on the wall, sleeve the large hanging pieces 45 and the small hanging pieces 48 onto the expansion bolts, and use nuts to lock the large hanging pieces 45 and the small hanging pieces 48 to complete the installation of the distribution box body 11.

[0045] Working principle:

[0046] In the first step, when installing, drill holes at appropriate distances at the installation positions on the wall surface, then pre-install the expansion bolts at the drilled positions and tighten them. Next, vertically sleeve the two large hanging pieces 45 onto the two upper screws 43, and then threadedly install the two hexagonal nuts 44 onto the two screws 43. At this time, under the action of the two sets of straightening blocks 46, the two large hanging pieces 45 can be kept in a vertical position. Then, slide the two adjusting blocks 42 inside the mounting frame 41 according to the positions of the expansion bolts so that the distance between the two adjusting blocks 42 is equal to the distance between the two expansion bolts. At this time, the position can be fixed by rotating the hexagonal nuts 44 on the screws 43. Next, sleeve the two small hanging pieces 48 onto the two lower screws 43. Under the action of the two sets of straightening bars 47, the two small hanging pieces 48 can be kept in a horizontal position. Then, adjust the positions of the two small hanging pieces 48 according to the positions of the expansion bolts. After adjustment, fix them with the hexagonal nuts 44; After the fixation is completed, hang the distribution box body 11 on the wall, sleeve the large hanging pieces 45 and the small hanging pieces 48 onto the expansion bolts, and use nuts to lock the large hanging pieces 45 and the small hanging pieces 48 to complete the installation of the distribution box body 11. By designing the device as an adjustable installation method, during installation, only the distance needs to be adjusted by sliding according to the positions of the expansion bolts, without cumbersome measurement and positioning, greatly shortening the installation time and improving work efficiency. Moreover, through the two sets of straightening blocks 46, the two large hanging pieces 45 can be kept in a vertical position, and through the two sets of straightening bars 47, the two small hanging pieces 48 can be kept in a horizontal position. This structural design with the cooperation of multiple components can more evenly disperse the weight of the distribution box body 11, enhance the overall stability, and reduce potential safety hazards caused by shaking or displacement;

[0047] Step 2: When the device is placed outdoors on a sunny day and needs to dissipate heat due to high temperature, the limiting strip 19 can be flipped outwards inside the second inner groove 18 at this time. Then, the connecting rods 23 at both ends are slid into the top plate 14. Driven by the movement of the two connecting rods 23, the two sliding strips 25 will slide inside the two first sliding grooves 17 accordingly. The connecting rod 23 in the middle will form a shielding protection. When the sliding strip 25 slides to the end, the limiting strip 19 can be released to reset and slide into the card slot 26 to limit the sliding strip 25. At the same time, the first spring 22 will be compressed. At this time, the connecting rod 23 will drive the protection plate 31 to slide synchronously. When the protection plate 31 slides, the second heat dissipation groove 32 will overlap with the first heat dissipation groove 13. At this time, the second heat dissipation groove 32 and the first heat dissipation groove 13 will form a heat dissipation channel, and the air inside the distribution box body 11 will circulate. Through the ingenious structural design of the device, when the device needs to dissipate heat outdoors at high temperature, an effective heat dissipation channel can be quickly constructed, allowing the air inside the distribution box body 11 to circulate, accelerating heat dissipation, effectively reducing the internal temperature of the device, ensuring the stable operation of the device in a high-temperature environment, and avoiding performance degradation or failure caused by overheating;

[0048] Step 3: When it rains, first unlock the limiting strip 19, and then the first spring 22 will recover its deformation and drive the connecting rods 23 and the protection plate 31 at both ends to reset. The second heat dissipation groove 32 on the protection plate 31 will be misaligned with the first heat dissipation groove 13, completing the sealing of the first heat dissipation groove 13 and the second heat dissipation groove 32 to prevent rainwater from entering the distribution box body 11 through the first heat dissipation groove 13. At this time, the distribution box body 11 will dissipate heat through the wire groove 49, and the heat will dissipate downward through the heat dissipation cover 57. At the same time, the silica gel strip 27 will be pressed against the wall and fit. At this time, the connecting rod 23, the drainage plate 24 and the protection plate 31 will form a closed structure, and the rainwater will be drained out through the drainage plate 24, so that the internal installation structure will not come into contact with the rainwater and rust, greatly extending the service life of the device and ensuring the stable operation of the device in a humid environment;

[0049] Step 4: When the wall surface is uneven, since the multiple connecting rods 23 are separate individuals, the multiple connecting rods 23 will adjust adaptively accordingly. This adaptive sealing structure enables the device to not only be applicable to conventional installation environments, but also play a good waterproof and protective effect under some complex wall conditions, expanding the applicable range of the device;

[0050] Step 5: After installation, the corner protection strip 39 can be moved outwards in the two protection plates 31. At this time, the corner protection strip 39 will drive the dovetail protection strip 36 to slide outwards 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 combination of the dovetail protection strip 36 and the corner protection strip 39 protects the shell and corners of the distribution box body 11. The cooperation of the corner protection strip 39, the dovetail protection strip 36 and the fixing bolt 35 enables the dovetail protection strip 36 and the corner protection strip 39 to be retractable when not in use, without affecting the appearance and normal use of the equipment; when protection is needed, they can be quickly unfolded and fixed, taking into account both the aesthetics and protection requirements of the equipment;

[0051] Step 6: When installing, 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 sliding rod 52 is pulled outwards. The movement of the sliding rod 52 will drive the connecting strip 53 to move accordingly. At this time, the wire pipe 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 pipe 55, and then the sliding rod 52 is released. The second spring 56 will drive the wire pipe 55 to reset, protecting and storing the connecting wires through the wire pipe 55. Moreover, when protecting, the slider 54 can slide inside the connecting strip 53 to adjust the storage position of the connecting wires. This equipment 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.
