Description

Technical Field

[0001] This invention relates to the field of distribution box technology, specifically to an integrated distribution box and waterproof components for incoming and outgoing lines. Background Technology

[0002] Integrated distribution boxes are widely used in construction, municipal, and industrial fields. They integrate various electrical components such as circuit breakers, metering instruments, and protection devices. When the distribution box is installed outdoors or in a humid environment, preventing rainwater and moisture from entering the interior through the gaps in the box (especially the cable inlet and outlet) is the key to ensuring its safe and stable operation.

[0003] Chinese patent application number 202410390258.0 discloses an integrated distribution box with waterproof cable connectors for incoming and outgoing lines, belonging to the field of distribution box technology. Its key technical features include: a distribution box body, with a waterproof connector and a power distribution component placement rack installed inside; a protective unit rotatably connected to the distribution box body; a rotating unit rotatably connected to the distribution box body, connected to the power distribution component placement rack via a self-rotating unit; a fastening unit slidably connected inside the waterproof connector; and a fixing unit snapped onto the waterproof connector. However, in actual use, there are often large gaps between the cables at the incoming and outgoing lines of the distribution box, allowing external rainwater and moisture to still enter the box, resulting in poor waterproofing.

[0004] In addition, when the incoming and outgoing lines are pulled by external forces, the connection between the cables and the electrical equipment inside the distribution box may become loose or even break, thus affecting the power supply. Summary of the Invention

An elastic bladder is provided between the two support rings, and one of the support rings is provided with an air inlet, which communicates with the interior of the elastic bladder through an air hole.

[0014] Preferably, the annular seat is fixedly sleeved on the vertical section of the bend;

[0015] The driving structure includes a turntable rotatably connected to an annular seat, and the surface of the turntable is provided with arc-shaped grooves, which are distributed in a ring array on the turntable.

[0016] The guide seats are arranged in a ring array at the ends of the ring seats.

[0017] Preferably, the fixing structure includes a sliding groove formed on the bottom surface of the guide seat, a sliding block slidably connected in the sliding groove, a limiting groove formed on the top of the sliding groove, a transmission rod provided on the sliding block, the transmission rod passing through the limiting groove and cooperating with the arc-shaped groove;

[0018] The slide is equipped with a fixing plate via a bracket. The fixing plate has an arc-shaped structure and is distributed in a ring array. The fixing plate is located inside the vertical section of the bend. When the fixing plates are closed together, they form a cylindrical structure.

[0019] Preferably, the side plate is located on the vertical section of the bend;

[0020] An elastic sheet is provided between the side of the positioning plate and the side plate. The toothed ring is located on the top of the turntable. The top of the toothed ring is provided with ratchet teeth in a ring array that cooperate with the bottom end of the positioning plate.

[0021] A torsion spring is fitted onto the vertical section of the bend, and the two ends of the torsion spring are fixedly connected to the bend and the turntable, respectively.

[0022] Preferably, the rotating ring is rotatably connected inside the horizontal section of the bend;

[0023] The movable grooves are located on both sides of the horizontal section of the bend, and the movable grooves correspond to the positions of the rotating ring.

[0024] Preferably, the torsion mechanism further includes a limiting structure, the limiting structure including a side seat, the side seat being disposed on the vertical section of the bend, a movable rod slidingly passing through the side seat, the top end of the movable rod being provided with a wedge-shaped seat, the wedge-shaped seat cooperating with the movable seat, and a limiting spring being sleeved on the top of the movable rod.

[0025] Preferably, the bottom end of the movable rod is provided with a limiting ring seat, which is hooked to the bent rod for emergency release of the torsion of the limiting ring seat.

[0026] Compared with the prior art, the present invention has the following beneficial effects:

[0027] 1. This invention uses the rotating ring of the torsion mechanism to drive the baffle to rotate, causing multiple incoming and outgoing cables passing between the baffles to twist and strand together, effectively eliminating gaps between the cables. Then, high-pressure gas is injected into the elastic bladder through the air inlet of the sealing mechanism, causing the elastic bladder to expand within the bend of the tube, tightly wrapping the outer circumference of the stranded cables and adhering to the inner wall of the tube, completely filling all gaps between the cables and the tube. This completely prevents external rainwater, moisture, and impurities from entering the box through the gaps between the cables or between the cables and the tube, significantly improving the waterproof reliability of the distribution box in outdoor or humid environments.

[0028] 2. This invention uses a rotating turntable to drive multiple arc-shaped fixing plates to converge towards the center through the cooperation of the arc-shaped groove and the transmission rod. This clamps and gathers the cables in the vertical section of the bend. At the same time, the toothed ring and the positioning plate of the positioning structure form a one-way positioning under the action of the elastic sheet, preventing the turntable from rotating in the opposite direction. This achieves continuous fixation of the cables and effectively blocks the transmission of external pulling force to the connection end of the electrical components inside the box. This prevents the cables from becoming loose, falling off, or even breaking due to external pulling, thus ensuring the stable operation of the power supply system.

[0029] 3. The guide seat of the fixing mechanism of the present invention is sleeved on the limiting rod, and the buffer spring at the outer end of the limiting rod is elastically engaged with the guide seat. When the cable is subjected to external tension within the normal range, the tension is transmitted to the guide seat through the fixing plate. The guide seat slides slightly along the limiting rod and compresses the buffer spring. The elastic deformation of the buffer spring absorbs the tension energy, avoiding the tension from acting directly on the bend and the box, preventing the box from shaking due to force and causing vibration of internal electrical components, and reducing the damage to the cable insulation layer caused by excessive instantaneous tension, thus extending the service life of the cable.

[0030] 4. When the external tensile force on the cable exceeds a preset threshold, the guide seat drives the bent rod downward under the action of the tensile force. The bent rod pulls the limiting ring seat and the movable rod to move downward simultaneously, so that the wedge seat and the movable seat are disengaged, and the limitation on the movable seat is released. At this time, the reset spring contracts and resets, driving the rotating ring to rotate in the opposite direction, so that the originally twisted cable returns to a dispersed state, releasing the reserved length margin of the cable. The extension of the length margin offsets the high-strength tensile force, avoiding damage to the bend, box and internal electrical components by the excessive tensile force, and further improving the safety and power supply stability of the distribution box.

[0038] The technical solutions of the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of the present invention.

[0039] Example 1

[0040] Please see Figure 1-6 This embodiment provides a comprehensive power distribution box, including a box body 1. The bottom and top sides of the box body 1 are provided with inlet and outlet holes 101, and the box body 1 also includes an inlet and outlet waterproof component provided on the inlet and outlet holes 101.

[0041] The waterproof assembly for the inlet and outlet lines includes a bend 2, and a sealing mechanism 3 is provided inside the bend section of the bend 2.

[0042] Specifically, the bend 2 is located on the side of the housing 1 and corresponds to the position of the inlet / outlet hole 101, for the cable to pass through. The bend design of the bend 2 can guide the liquid to flow downward and prevent it from flowing directly into the housing 1. The sealing mechanism 3 is used to fill the bend section of the bend 2 to fill and seal the gap around the inlet / outlet cable. The fixing mechanism 4 is used to gather and fix the inlet / outlet cable. The twisting mechanism 5 is used to drive the inlet / outlet cable to twist appropriately so that the inlet / outlet cable is stranded.

[0043] The sealing mechanism 3 includes two corresponding support rings 301, which are respectively located at opposite ends of the vertical and horizontal sections of the bend 2. An elastic bladder 302 is provided between the two support rings 301. One of the support rings 301 is provided with an air inlet 303, which communicates with the interior of the elastic bladder 302 through an air hole.

[0044] Specifically, the support ring 301 is used to support the incoming and outgoing cables passing through the bend section of the bend pipe 2, preventing the incoming and outgoing cables from sticking to the inner wall of the bend pipe 2, so as to leave an annular space for the expansion of the elastic bladder 302. The elastic bladder 302 is made of elastic material. The initial shape of the elastic bladder 302 is an annular structure and its shape matches the bend section of the bend pipe 2. When air is inflated into the elastic bladder 302, the elastic bladder 302 will expand towards the center to wrap the incoming and outgoing cables. An air inlet 303 is provided with an air inlet one-way valve.

[0045] In use, the inlet and outlet cables are first passed through the vertical section, the bend section and the horizontal section of the bend pipe 2, and introduced into or led out of the housing 1. High pressure gas is supplied into the air inlet 303 to cause the elastic bladder 302 to expand, thereby sealing the area around the inlet and outlet cables in the bend section.

[0046] However, because the various inlet and outlet cables are scattered and the gaps between them are large, even after the elastic bladder 302 wraps the cables, there are still large gaps between them. External moisture and water vapor can still enter the interior of the housing 1 through these gaps. Therefore, the following improvements are made:

[0047] The vertical section of the bend 2 is provided with a fixing mechanism 4. The fixing mechanism 4 includes an annular seat 401 and a guide seat 404. The annular seat 401 is fixedly sleeved on the vertical section of the bend 2. The annular seat 401 is provided with a driving structure. The driving structure includes a turntable 402 rotatably connected to the annular seat 401. The surface of the turntable 402 is provided with an arc-shaped groove 403. The arc-shaped grooves 403 are distributed in a ring array on the turntable 402.

[0048] The guide seats 404 are arranged in a ring array at the end of the ring seat 401. The guide seats 404 are provided with a fixing structure, which includes a groove 405 opened on the bottom surface of the guide seats 404. A slide seat 406 is slidably connected in the groove 405. A limit groove 407 is opened at the top of the groove 405. A transmission rod 408 is provided on the slide seat 406. The transmission rod 408 passes through the limit groove 407 and cooperates with the arc-shaped groove 403. A fixing plate 410 is provided on the slide seat 406 through a bracket 409. The fixing plate 410 is an arc-shaped structure and is distributed in a ring array. The fixing plate 410 is located inside the vertical section of the bend 2. When the fixing plates 410 are closed, they are combined to form a cylindrical structure.

[0049] Specifically, by rotating the turntable 402, the transmission rod 408 is driven to move along the limiting groove 407 towards the center of the turntable 402 by the cooperation of the arc groove 403 and the transmission rod 408. At the same time, the transmission rod 408 drives the slide 406, the bracket 409 and the fixing plate 410 to move towards the center of the turntable 402, thereby realizing the closing of each fixing plate 410, so that the fixing plates 410 of each arc structure are enclosed into a cylinder to gather and fix the incoming and outgoing cables.

[0050] It also includes a positioning structure, which includes a side plate 413 and a toothed ring 416. The side plate 413 is located in the vertical section of the bend 2. A positioning plate 414 slides through the side plate 413 for cooperating with the toothed ring 416 to position the turntable 402. An elastic piece 415 is provided between the side of the positioning plate 414 and the side plate 413.

[0051] A torsion spring 417 is fitted onto the vertical section of the bend 2, and the two ends of the torsion spring 417 are fixedly connected to the bend 2 and the turntable 402, respectively.

[0052] A toothed ring 416 is located on the top of the turntable 402. The top of the toothed ring 416 is provided with ratchet teeth arranged in a ring array to engage with the bottom end of the positioning plate 414.

[0053] Specifically, during the rotation of turntable 402, torsion spring 417 is elastically torsion and in an energy storage state. At the same time, the ratchet on the toothed ring 416 passes the bottom end of positioning plate 414, and under the action of elastic sheet 415, positioning plate 414 moves up and down reciprocally. The positioning plate 414 and ratchet are used to position turntable 402, preventing turntable 402 from rotating in the opposite direction, and realizing continuous fixation of incoming and outgoing cables.

[0054] The horizontal section of the bend 2 is provided with a torsion mechanism 5, which includes a rotating ring 501 and a movable groove 504. The rotating ring 501 is rotatably connected inside the horizontal section of the bend 2. The inner wall of the rotating ring 501 is provided with a stop bar 502 in a ring array. The movable groove 504 is opened on both sides of the horizontal section of the bend 2. The movable groove 504 corresponds to the position of the rotating ring 501. The rotating ring 501 is provided with a movable seat 505 that cooperates with the movable groove 504. A return spring 506 is provided between the movable seat 505 and the bend 2.

[0055] Specifically, by passing each inlet and outlet cable through the gaps between two adjacent baffles 502, and after the inlet and outlet cables at the bottom of the bend 2 are fixed by the fixing mechanism 4, the rotating ring 501 is rotated by moving the movable seat 505, the return spring 506 is stretched, and then the inlet and outlet cables are twisted by the baffles 502, so that the inlet and outlet cables in the bend 2 are spirally combined into one. At this time, the cross-section of the inlet and outlet cables is close to that of the cylindrical seat, thereby eliminating the gaps between the inlet and outlet cables, and cooperating with the sealing mechanism 3 to achieve a complete seal inside the bend 2, thus improving the waterproof effect.

[0056] It also includes a limiting structure, which includes a side seat 507. The side seat 507 is located on the vertical section of the bend 2. A movable rod 508 slides through the side seat 507. A wedge-shaped seat 509 is provided at the top of the movable rod 508. The wedge-shaped seat 509 cooperates with the movable seat 505. A limiting spring 510 is sleeved on the top of the movable rod 508.

[0057] Specifically, when one movable seat 505 is moved, the other movable seat 505 rotates in the opposite direction and passes through the wedge seat 509. When the movable seat 505 contacts the inclined surface of the wedge seat 509, it drives the wedge seat 509 to move the movable rod 508 downward. The limiting spring 510 is compressed. When the movable seat 505 has completely passed through the wedge seat 509, the wedge seat 509 returns to its initial position under the reset action of the limiting spring 510, thereby forming a blocking limit on the movable seat 505 and preventing the movable seat 505 from being pulled back and reset by the reset spring 506.

[0058] During use, as the incoming and outgoing cables pass through the bend 2, each cable passes through the gap between the stop bars 502. The turntable 402 is rotated manually or with a tool. The arc-shaped groove 403 on the surface of the turntable 402 engages with the transmission rod 408, pushing the transmission rod 408 along the limiting groove 407 towards the center of the turntable 402. This, in turn, causes the slide 406, bracket 409, and fixing plate 410 to move inward synchronously. Multiple arc-shaped fixing plates 410 gradually close together, ultimately forming a cylindrical structure that encloses the vertical section of the bend 2. The scattered cables are gathered and clamped in place. During this process, the torsion spring 417 is twisted and stores energy. The toothed ring 416 rotates with the turntable 402. The ratchet on the top of the toothed ring 416 engages with the positioning plate 414 and achieves unidirectional positioning under the action of the elastic plate 415, preventing the turntable 402 from rotating back. This maintains the continuous fixation of the cables entering and exiting the vertical section of the bend 2, while blocking the further transmission of external tension on the cables entering and exiting, preventing external tension from pulling the cables and causing the connection between the cables entering and exiting and the electrical components inside the housing 1 to loosen or fall off.

[0059] After fixing, moving the movable seat 505 on one side causes the rotating ring 501 to rotate, stretching the return spring 506. The rotating ring 501 causes the cables to twist relative to each other through the stop bar 502, so that the cables are spirally twisted together in the bend 2, effectively eliminating the gaps between the cables. At the same time, the movable seat 505 on the other side moves in the opposite direction and passes through the wedge seat 509. The wedge seat 509 squeezes the movable rod 508 under the action of the inclined plane, compressing the limit spring 510. When the movable seat 505 passes the wedge seat 509, the wedge seat 509 is lifted up under the reset action of the limit spring 510, forming a mechanical limit to prevent the rotating ring 501 from rotating back under the action of the return spring 506, thus maintaining the twisted state of the cables.

[0060] After the cables entering and exiting the bend 2 are fixed and twisted into strands, high-pressure gas is injected into the elastic bladder 302 through the air inlet 303. The elastic bladder 302 expands within the bend section of the bend 2, tightly wrapping the stranded cables and filling all gaps between the cables and the inner wall of the bend 2, achieving a complete seal inside the bend 2 and effectively preventing the intrusion of external moisture, rainwater and other impurities.

[0061] Example 2

[0062] However, when the incoming and outgoing cables are subjected to external force, due to the fixing mechanism 4 securing the cables, the tension on the incoming and outgoing cables will directly act on the housing 1, causing the housing 1 to shake and triggering vibration of the internal electrical components. This can easily affect the power supply and damage the insulation layer of the incoming and outgoing cables. Therefore, the following improvements are made:

[0063] The fixing mechanism 4 also includes a limiting rod 411 located at the end of the annular seat 401, a guide seat 404 sleeved on the limiting rod 411, and a buffer spring 412 sleeved on the outer end of the limiting rod 411.

[0064] Specifically, the guide seat 404 slides along the limiting rod 411 by being sleeved on the limiting rod 411, and the buffer spring 412 is used to buffer the guide seat 404, thereby reducing the force exerted by the external force on the guide seat 404 and the inlet and outlet lines.

[0065] During use, when the incoming and outgoing cables are combined into one strand inside the bend 2, an appropriate length allowance is left in the vertical section inside the bend 2 in advance. When the incoming and outgoing cables are subjected to unexpected tension, the tension is transmitted to the guide seat 404 through the fixing plate 410. The guide seat 404 can slide slightly along the limiting rod 411 and compress the buffer spring 412 to achieve tension buffering, avoid the tension acting directly on the box 1, and at the same time prevent the connection point between the cable and the equipment inside the box 1 from being subjected to excessive force, which may cause it to loosen or fall off.

[0066] However, when the tension on the incoming and outgoing cables is too great, the force exerted by the guide seat 404 on the buffer spring 412 will exceed the compression limit of the buffer spring 412, which will still cause the tension to be exerted on the housing 1 through the fixing mechanism 4, threatening the stability of the power supply. Therefore, the following improvements are made:

[0067] The guide seat 404 has a bent rod 418 at its end, and the movable rod 508 has a limiting ring seat 511 at its bottom end. The limiting ring seat 511 is hooked to the bent rod 418 for emergency release of the torsion of the limiting ring seat 511.

[0068] Specifically, in the initial state, the bent portion of the bent rod 418 contacts the inner bottom surface of the limiting ring seat 511, providing leeway for the bent portion of the bent rod 418 to move within the limiting ring seat 511.

[0069] When in use, when the external tension value of the incoming and outgoing cables is within the normal threshold range, the external tension causes the guide seat 404 to slide slightly, the buffer spring 412 is slightly compressed, and moves slightly downward through the bent rod 418. The bent rod 418 will drive the limit ring seat 511 to drive the movable rod 508 and the wedge seat 509 to move slightly downward. However, at this time, the downward movement distance of the wedge seat 509 is not enough to disengage from the movable seat 505.

[0070] It should be noted that the normal threshold range is the maximum distance that the wedge seat 509 can move downwards without disengaging from the movable seat 505.

[0071] When the external tension on the incoming and outgoing cables exceeds the preset tension threshold, the tension acts on the guide seat 404 through the fixed plate 410, which pulls the bent rod 418 downward, thereby causing the limiting ring seat 511 and the movable rod 508 to move downward, causing the wedge seat 509 to disengage from the movable seat 505, releasing the limitation on the movable seat 505. At this time, the buffer spring 412 is just compressed to its limit. The retraction and reset of the return spring 506 drives the movable seat 505 and the rotating ring 501 to rotate in the opposite direction and reset, so that the incoming and outgoing cables that were twisted into a strand by the stop rod 502 return to their normal dispersed state, thereby releasing the length margin of the incoming and outgoing cables. In this way, when the tension on the incoming and outgoing cables is greater than the set tension threshold, the length margin released by the incoming and outgoing cables is used to offset the high-intensity external tension, preventing the high-intensity tension from acting on the bent pipe 2 and the housing 1 through the guide seat 404.

[0072] The above description is merely an embodiment of the present invention and does not limit the patent scope of the present invention. Any equivalent structural or procedural transformations made based on the content of the present invention's specification and drawings, or direct or indirect applications in other related technical fields, are similarly included within the patent protection scope of the present invention.
