Description
Technical Field
[0001] This invention relates to the field of power strip technology, and more specifically to a split-type power strip that can store electrical wires. Background Technology
[0002] Due to the structural design characteristics of existing detachable power strips, the independent cables must be connected to the main body of the power strip before power can be supplied. After use, the independent cables lack a suitable storage structure, making cable storage cumbersome and taking up a large overall volume, resulting in poor portability and causing many inconveniences for storage and carrying.
[0003] Meanwhile, due to the diverse usage scenarios of power strips, cables are easily exposed to water during use, such as condensation in humid environments or accidental spills. If the cables are not cleaned before storage, residual moisture will accelerate the aging and damage of the cable insulation layer, cause corrosion of the internal metal conductors, and may even seep into the power strip's connection ports, damaging contact performance and potentially leading to short circuits, leakage, and other safety hazards. This seriously affects the safety and lifespan of the power strip. Therefore, a split-type cable tray with retractable cables is proposed to improve the convenience of cable storage, reduce storage volume, and avoid problems such as cable insulation aging, conductor corrosion, and poor contact at the power strip ports caused by residual moisture during storage. This ensures safety and extends the product's lifespan. Summary of the Invention
[0004] To address the problems in existing technologies, this invention provides a split-type cable tray that can store cables, improving the convenience of cable storage, reducing storage volume, and avoiding problems such as cable insulation aging, conductor corrosion, and poor contact at the power strip ports caused by residual moisture not being cleaned during storage, thus ensuring safety and extending product lifespan.
[0005] The technical solution adopted by this invention to solve its technical problem is a split-type cable tray with cable storage, including a power strip. The bottom of the power strip is snapped with a housing for storing cables. The housing has a sealed cavity, and two sets of mounting plates are slidably connected in the sealed cavity. Each mounting plate has a winding assembly for winding cables on its adjacent side. One end of the cable has a terminal. The terminal passes through the mounting plate and the housing and is fixedly connected to the side of the housing. One end of the housing is fixedly connected to a locking and cleaning structure. The end of the cable away from the terminal passes through the mounting plate, the housing, and the locking and cleaning structure in sequence and is fixedly connected to a plug. Each of the two sets of mounting plates has an elastic air storage structure on its opposite side, and the elastic air storage structure is connected to the locking and cleaning structure.
[0006] Specifically, the winding assembly includes a fixing plate fixedly connected to the side of the mounting plate, a horizontally arranged winding rod fixedly connected between the two sets of fixing plates, several sets of rotating rings alternately arranged on the two sets of winding rods, and a limiting ring fixedly connected to the winding rod on both sides of each rotating ring. The cable alternately passes around the rotating rings of the two sets of winding rods; a compression spring is fixedly connected between the two sets of mounting plates.
[0007] Specifically, several sets of horizontally arranged limiting rods are fixedly connected inside the housing. The limiting rods pass through two sets of mounting plates and are slidably connected to the mounting plates in a sealed manner. The two ends of the limiting rods are fixedly connected to the inner wall of the housing.
[0008] Specifically, the locking and cleaning structure includes a sleeve fixed to one end of the housing. The sleeve has a threaded structure on its outer circumference. A plurality of circumferentially distributed elastic arc-shaped clamping plates are fixed to the end of the sleeve away from the housing. The arc-shaped clamping plates are arranged in a conical shape. A rotating cylinder is threaded to the outside of the sleeve. One end of the rotating cylinder has a conical cylinder that is pressed and fitted against the outside of the arc-shaped clamping plates. The cable passes through the sleeve and the arc-shaped clamping plates and is pressed and fitted against the inside of the arc-shaped clamping plates. A plurality of circumferentially distributed air vents are opened inside the sleeve.
[0009] Specifically, the elastic gas storage structure includes a folded airbag, the two ends of which are fixedly connected to the mounting plate and the inner wall of the housing, respectively. Both ends of the housing are provided with one-way air inlet connectors that communicate with the folded airbag. Dustproof nets corresponding to the one-way air inlet connectors are installed at both ends of the housing. A channel communicating with the folded airbag is opened inside the housing. The folded airbag communicates with the air outlet in the sleeve through the channel.
[0010] Specifically, the upper inner side of the housing is provided with a liquid storage chamber, which is filled with a thermally expanding fluid. The housing is provided with several sets of snap-fit grooves, and a telescopic cylinder is fixedly connected in the snap-fit grooves. One end of the telescopic cylinder is connected to the inside of the liquid storage chamber, and an arc-shaped retaining ring is fixedly connected to the output end of the telescopic cylinder. An arc-shaped limiting plate is fixedly connected to the inner side of the arc-shaped retaining ring.
[0011] The upper surface of the housing is provided with a pin hole that communicates with the snap-fit groove. The lower surface of the plug is provided with several sets of pins corresponding to the pin holes. The lower end of the pin is provided with a chamfer. The pin is provided with an arc-shaped snap-fit groove, which corresponds to the arc-shaped limiting plate.
[0012] Specifically, the upper surface of the housing is provided with several sets of mounting grooves, and a return spring is fixedly connected in the mounting groove. A compression ring is fixedly connected to the end of the return spring away from the mounting groove.
[0013] Specifically, the inner side of the housing has a groove in the middle, and a sleeve is fixedly connected in the groove. The lower end of the sleeve is connected to the sealing cavity. A press valve is connected in the sleeve. An expansion pad is fixedly connected to the outside of the cable near the terminal. The housing has an air outlet channel. The press valve is connected to the expansion pad through the air outlet channel and the pipeline. After the valve stem of the press valve extends, the press valve is connected to the expansion pad.
[0014] Specifically, the side of the housing is provided with an adjustment hole that communicates with the liquid storage chamber. An adjustment screw is threaded into the adjustment hole. A squeezing plate is fixedly connected to one end of the adjustment screw located in the liquid storage chamber. An elastic film is fixedly connected to the inner wall of the liquid storage chamber on all four sides of the squeezing plate.
[0015] The beneficial effects of this invention are:
[0016] (1) The split-type cable tray described in this invention achieves simultaneous fast and orderly cable storage and cleaning through the coordinated design of the winding component, the elastic air storage structure and the locking and cleaning structure, simplifying the storage operation, reducing the volume, and effectively removing moisture and impurities from the surface of the cable, avoiding insulation aging, conductor corrosion and poor port contact, reducing the risk of short circuit leakage and extending the service life of the product.
[0017] (2) The split-type cable tray described in this invention uses a multi-layer protection mechanism triggered by thermal expansion fluid. When the temperature is abnormally high, the plug strip is automatically unlocked from the housing. The reset spring pops the plug strip away and triggers the press valve, which not only cuts off the heat conduction path, but also alerts the user through the intuitive pop-out action. The press valve, which is triggered at the same time, causes the compressed gas in the sealed cavity to drive the expansion pad to expand, further widening the distance between the plug strip and the housing, strengthening the heat insulation protection effect, preventing the spread of fire, and providing support for the plug strip to maintain a regular posture, making it easy for the user to quickly carry out emergency response, and greatly improving the safety protection level of the product.
[0018] (3) The split-type cable tray described in this invention can quickly and seamlessly connect the power strip and the housing without additional tools by engaging the pin and the arc-shaped limiting plate, ensuring structural stability during use and carrying. At the same time, with the help of the design of the adjusting screw and the extrusion plate, rotating the screw can unlock the telescopic cylinder by extruding the thermal expansion fluid, realizing the non-destructive separation of the power strip and the housing. This facilitates the inspection and maintenance of the power strip circuit, the cables inside the housing and various components, avoids damage to components caused by manual prying, and improves the practicality and reusability of the product.

[0034] To make the technical means, creative features, objectives and effects of this invention easier to understand, the invention will be further described below in conjunction with specific embodiments.
[0035] To improve the convenience of cable storage, reduce storage volume, and avoid problems such as cable insulation aging, conductor corrosion, and poor contact at power strip ports caused by residual moisture during storage, thereby ensuring safety and extending product lifespan, as one embodiment of the present invention, such as... Figure 1 , Figure 2 , Figure 3 , Figure 5 , Figure 6 As shown, the present invention discloses a split-type cable tray for storing cables, comprising a power strip 1, a housing 3 for storing cables 2 being snapped into the bottom of the power strip 1, a sealed cavity 4 being provided inside the housing 3, and two sets of mounting plates 5 being slidably connected inside the sealed cavity 4, each of the mounting plates 5 having a winding assembly for winding the cables 2 on its adjacent side, one end of the cables 2 having a terminal 6, the terminal 6 passing through the mounting plate 5 and the housing 3 and being fixedly connected to the side of the housing 3, one end of the housing 3 being fixedly connected to a locking and cleaning structure, and the end of the cables 2 away from the terminal 6 passing through the mounting plate 5, the housing 3 and the locking and cleaning structure in sequence and being fixedly connected to a plug 7; each of the two sets of mounting plates 5 having an elastic air storage structure on its opposite side, the elastic air storage structure being connected to the locking and cleaning structure.
[0036] When in use, first connect the terminal 6 of cable 2 to the corresponding interface of power strip 1 to complete the circuit connection and solve the basic usage requirement that the existing split power strip 1 needs to be connected to cable 2 separately.
[0037] When using the power strip 1, the locking and cleaning structure is operated to release the clamping limit on the end of the cable 2 near the plug 7. Then, the plug 7 is pulled to extend the cable 2 out of the housing 3. During the movement of the cable 2, the two sets of winding components are driven simultaneously, causing the two sets of mounting plates 5 to move closer together along the sealing cavity 4, so that the cable 2 can be smoothly pulled out and adjusted to the appropriate length to meet the power supply distance requirements in different scenarios. When the mounting plates 5 move towards each other, the elastic gas storage structure is driven simultaneously to complete the energy storage action, storing power for the subsequent cleaning of the cable 2.
[0038] After cable 2 is pulled out to the target length, the locking and cleaning structure is adjusted again to form a snap-fit limit on the outside of cable 2, preventing cable 2 from automatically retracting into the sealed cavity 4, ensuring the stability of cable 2 during use, and avoiding the normal power supply of electrical equipment due to cable 2 loosening.
[0039] When storing cable 2 after using power strip 1, the locking and cleaning structure is adjusted to release the clamping and fixing of cable 2; the two sets of mounting plates 5 are reset and moved. When the mounting plates 5 move, the corresponding winding components are reset synchronously. Under the traction of the winding components, the pulled-out cable 2 is recycled into the sealed cavity 4, realizing the quick storage of cable 2, greatly simplifying the storage operation, reducing the overall storage volume, improving portability, and solving the problem of cumbersome storage of cable 2 and large space occupation of existing split power strip 1.
[0040] When the mounting plate 5 is reset and moved, it squeezes the elastic air storage structure to supply air to the locking and cleaning structure. As the cable 2 enters the housing 3 through the locking and cleaning structure, the dust and residual moisture on the surface of the cable 2 are effectively removed by the locking and cleaning structure, preventing dust and moisture from entering the sealed cavity 4 with the cable 2. This prevents moisture from accelerating the aging and damage of the cable 2's insulation layer and causing corrosion of the internal metal conductor. At the same time, it prevents impurities from seeping into the connection port of the power strip 1 and damaging the contact performance, reducing safety hazards such as short circuits and leakage, ensuring the safety of the power strip 1 and extending the product's service life.
[0041] To facilitate pulling cable 2 out, for example, as follows: Figure 5 , Figure 6 , Figure 7 As shown, the present invention also includes a winding assembly comprising a fixing plate 8 fixedly connected to the side of the mounting plate 5, a horizontally arranged winding rod 9 fixedly connected between the two sets of fixing plates 8, a plurality of rotating rings 10 alternately arranged on the two sets of winding rods 9, and a limiting ring 11 fixedly connected to the winding rod 9 on both sides of the rotating ring 10, wherein the cable 2 alternately passes around the rotating rings 10 of the two sets of winding rods 9; and a compression spring 12 fixedly connected between the two sets of mounting plates 5.
[0042] When in use, in the initial storage state, the cable 2 is alternately wound around the swivels 10 of the two sets of winding rods 9. The limiting rings 11 on both sides of the swivels 10 can limit the cable 2, preventing the cable 2 from falling off or shifting from the winding rods 9, and ensuring that the cable 2 is arranged neatly when initially stored.
[0043] When the plug 7 is pulled to extend the cable 2 to the outside of the housing 3, the cable 2 will simultaneously generate a uniform traction force on the two sets of winding rods 9. This traction force overcomes the elastic force of the compression spring 12, drives the two sets of mounting plates 5 to move closer to each other, and then drives the two sets of winding rods 9 to move closer to each other, so as to facilitate pulling the cable 2 out.
[0044] When cable 2 extends to the target length, the locking and cleaning structure clamps and limits cable 2. At this time, the compressed compression spring 12 will generate a continuous reverse thrust on the two sets of mounting plates 5, so that the two sets of winding rods 9 maintain a moderate tension on cable 2, preventing cable 2 from loosening or retracting due to vibration during use, ensuring the stability of power supply to the electrical equipment, and at the same time avoiding the mess caused by excessive slack of cable 2.
[0045] After cable 2 is used, the clamping and cleaning structure is released, the compression spring 12 releases its stored force, and pushes the two sets of mounting plates 5 to reset. The mounting plates 5 drive the corresponding winding rods 9 to separate synchronously. The fixed rotating ring 10, in conjunction with the alternating winding design, generates a uniform traction force on cable 2, guiding cable 2 to be orderly wound back onto the two sets of winding rods 9 along the channel formed by the rotating ring 10 and the limiting ring 11. This avoids problems such as knotting, tangling, or messy arrangement of cable 2 during recycling, enabling cable 2 to be quickly and neatly stored, simplifying the storage operation, reducing the overall storage volume, and improving product portability.
[0046] To ensure the stability of cable 2 during the pulling-out process, for example, such as Figure 5 , Figure 6 , Figure 7 As shown, the present invention also includes a plurality of horizontally arranged limiting rods 13 fixedly connected inside the housing 3. The limiting rods 13 pass through two sets of mounting plates 5 and are slidably connected to the mounting plates 5 in a sealed manner. The two ends of the limiting rods 13 are fixedly connected to the inner wall of the housing 3.
[0047] When in use, when the plug 7 is pulled to extend the cable 2, the two sets of mounting plates 5 move towards each other under the pulling force. The limiting rod 13 can ensure that the mounting plates 5 slide in a fixed direction, ensuring that the two sets of winding rods 9 approach each other synchronously and smoothly, avoiding uneven force and pulling damage to the cable 2 caused by the shaking of the mounting plates 5, and ensuring the stability of the cable 2 during the pulling process.
[0048] To reduce the risk of short circuits and leakage, for example, such as Figure 8 , Figure 9 As shown, the present invention also includes a sleeve 14 fixed to one end of the housing 3, the sleeve 14 having a threaded structure on its outer periphery, and a plurality of circumferentially distributed elastic arc-shaped clamping plates 15 fixed to the end of the sleeve 14 away from the housing 3, the arc-shaped clamping plates 15 being arranged in a conical shape; a rotating cylinder 16 is threadedly connected to the outer side of the sleeve 14, and a conical cylinder 17 is provided at one end of the rotating cylinder 16 that is pressed and fitted against the outer side of the arc-shaped clamping plates 15; the cable 2 passes through the sleeve 14 and the arc-shaped clamping plates 15 and is pressed and fitted against the inner side of the arc-shaped clamping plates 15; a plurality of circumferentially distributed vent holes 18 are opened inside the sleeve 14.
[0049] When using the cable 2, rotate the drum 16. Utilize the threaded structure of the sleeve 14 to drive the conical cylinder 17 away from the elastic arc-shaped clamping plate 15, thereby relieving the compression of the conical cylinder 17 on the arc-shaped clamping plate 15. After the arc-shaped clamping plate 15 elastically resets, it releases the cable 2, allowing the cable 2 to pass through the sleeve 14 and the arc-shaped clamping plate 15. This prevents damage to the cable 2 during pulling and ensures a smooth pulling process.
[0050] After cable 2 is pulled out to the target length, the rotating drum 16 is rotated in the opposite direction. The conical drum 17 gradually squeezes the outer side of the arc-shaped clamping plate 15, causing the arc-shaped clamping plate 15 to contract towards the center and fit tightly against the outer side of cable 2. The arc-shaped clamping plate 15 fixes cable 2 to prevent cable 2 from retracting or loosening during use, thus ensuring stable power supply.
[0051] When cable 2 is recycled, the gas in the elastic gas storage structure is ejected through the air outlet 18 inside the sleeve 14. The airflow is evenly distributed around the cable 2 and blown towards the end of the arc-shaped clamping plate 15 away from the rotating drum 16. This can not only efficiently dry the residual moisture on the surface of cable 2, but also blow out the attached dust and other impurities, preventing moisture and impurities from entering the sealed cavity 4 with cable 2, preventing the insulation layer of cable 2 from aging and the metal conductor from corroding, and reducing the risk of short circuits and leakage.
[0052] For example, such as Figure 4 , Figure 8 As shown, the present invention also includes the following: the elastic air storage structure includes a folded airbag 19, the two ends of which are fixedly connected to the mounting plate 5 and the inner wall of the housing 3, respectively; both ends of the housing 3 are provided with one-way air inlet connectors 20 communicating with the folded airbag 19; both ends of the housing 3 are provided with dustproof nets 21 corresponding to the one-way air inlet connectors 20; a channel communicating with the folded airbag 19 is opened in the housing 3; and the folded airbag 19 communicates with the air outlet 18 in the sleeve 14 through the channel.
[0053] When in use, when cable 2 is pulled out, the two sets of mounting plates 5 are pulled closer together, causing the folding airbags 19 at both ends to unfold synchronously. The unfolding of the folding airbags 19 generates negative pressure, which actively draws in external gas through the one-way air inlet connectors 20 at both ends of the housing 3 to complete the gas storage and energy storage.
[0054] After cable 2 is used up, the locking cleaning structure is released from fixing cable 2, the squeeze spring 12 releases the stored force, and drives the two sets of mounting plates 5 to reset. When the mounting plates 5 reset, they squeeze the folded airbag 19. The pressurized gas in the folded airbag 19 is directionally transported to the air outlet 18 of the sleeve 14 through the channel in the housing 3, providing a continuous and stable airflow for cleaning cable 2, ensuring that the residual moisture on the surface of cable 2 is dried and the attached impurities are blown out.
[0055] Meanwhile, the elastic cushioning characteristics of the folding airbag 19 and the elastic force of the compression spring 12 work together to effectively slow down the reset speed of the mounting plate 5, avoiding knotting, tangling or pulling damage to the cable 2 during retraction due to excessive reset, and ensuring that the cable 2 is stored smoothly and neatly.
[0056] The dustproof net 21 can prevent external dust and other impurities from entering the channels inside the folded airbag 19 and the shell 3 during the air intake process, thus avoiding the accumulation of impurities and airflow blockage.
[0057] To improve portability and ease of use, for example, such as Figure 4 , Figure 10 , Figure 11 As shown, the present invention also includes a liquid storage chamber 22 provided on the upper inner side of the housing 3, the liquid storage chamber 22 being filled with a thermally expanding fluid, a plurality of sets of snap-fit grooves 23 provided inside the housing 3, a telescopic cylinder 24 fixedly connected in the snap-fit grooves 23, one end of the telescopic cylinder 24 communicating with the inside of the liquid storage chamber 22, an arc-shaped retaining ring 25 fixedly connected to the output end of the telescopic cylinder 24, and an arc-shaped limiting plate 26 fixedly connected to the inner side of the arc-shaped retaining ring 25;
[0058] The upper surface of the housing 3 is provided with a pin hole 27 that communicates with the snap-fit groove 23. The lower surface of the plug bar 1 is provided with a number of pin rods 28 corresponding to the pin hole 27. The lower end of the pin rod 28 is provided with a chamfer. The pin rod 28 is provided with an arc-shaped snap-fit groove 29, which corresponds to the arc-shaped limiting plate 26.
[0059] In use, the pin 28 is aligned with the pin hole 27 and inserted vertically. The chamfer at the lower end of the pin 28 presses against the arc-shaped limiting plate 26, driving the arc-shaped limiting plate 26 to move the arc-shaped retaining ring 25 synchronously. This causes the output end of the telescopic cylinder 24 to extend along the retaining groove 23, reserving a channel for the pin 28 to move down. When the pin 28 moves down to the arc-shaped retaining groove 29 and aligns with the arc-shaped limiting plate 26, the output end of the telescopic cylinder 24 automatically resets, pulling the arc-shaped limiting plate 26 into the arc-shaped retaining groove 29 to form a limit lock, completing the connection between the power strip 1 and the housing 3. No additional tools are required, the connection operation is convenient and efficient, ensuring the overall structural stability and improving the convenience of carrying and using.
[0060] When the cable 2 inside the housing 3 experiences abnormally high temperatures due to short circuits, overloads, or other reasons, the heat is rapidly transferred to the liquid storage chamber 22, causing the thermally expanding fluid inside the liquid storage chamber 22 to expand. When the temperature rises to a preset safety threshold, the expanded thermally expanding fluid generates sufficient thrust to push the output end of the telescopic cylinder 24 to extend continuously, causing the arc-shaped retaining ring 25 and the arc-shaped limiting plate 26 to move outward synchronously until the arc-shaped limiting plate 26 completely disengages from the arc-shaped retaining groove 29 on the pin 28, releasing the locking restriction on the pin 28. At this time, the power strip 1 and the housing 3 lose their locking and separation under their own weight or slight external force, which can block the transmission of abnormal high temperatures to the main body of the power strip 1, preventing the internal circuit components of the power strip 1 from being damaged by high temperatures or causing more serious burnout faults. By cutting off the heat conduction path, it buys users emergency handling time and significantly improves the safety protection level of the product.
[0061] To facilitate the quick ejection of the power strip 1 from the housing 3, for example, as shown... Figure 10 , Figure 11 As shown, the present invention also includes a plurality of mounting grooves 30 on the upper surface of the housing 3, a return spring 31 fixedly connected in the mounting groove 30, and a compression ring 32 fixedly connected to the end of the return spring 31 away from the mounting groove 30.
[0062] When the power strip 1 is engaged with the housing 3, the lower surface of the power strip 1 contacts the compression ring 32 and is pressed downwards, causing the return spring 31 to contract and store force along the mounting groove 30. When the cable 2 inside the housing 3 experiences abnormally high temperature, the thermal expansion fluid drives the telescopic cylinder 24 to release the engagement lock between the power strip 1 and the housing 3. The retracted return spring 31 then quickly releases its stored force, generating an instantaneous upward thrust through the compression ring 32, which quickly springs the power strip 1 away from the housing 3. This springing action can intuitively and strongly attract the user's attention, promptly alerting them to potential safety hazards and facilitating the user to quickly identify and take emergency measures such as power outages and fire extinguishing. At the same time, after the power strip 1 is springed away, it is completely separated from the housing 3, further cutting off the heat conduction path and preventing the power strip 1 from being continuously baked by high temperature, which could lead to secondary combustion or complete damage to the circuit components.
[0063] To avoid the situation where the power strip 1 and the housing 3 come into contact again after separation due to the installation position of the power strip 1, for example, such as Figure 12 As shown, the present invention also includes a groove 33 in the middle of the inner side of the housing 3, a sleeve 34 fixedly connected in the groove 33, the lower end of the sleeve 34 communicating with the sealing cavity 4, a press valve 35 connected in the sleeve 34, an expansion pad 36 fixedly connected to the outside of the cable 2 near the terminal 6, an air outlet channel in the housing 3, the press valve 35 communicating with the expansion pad 36 through the air outlet channel and pipeline, and the valve stem of the press valve 35 extending out to connect the press valve 35 with the expansion pad 36.
[0064] When in use, when cable 2 is pulled out, the two sets of mounting plates 5 approach each other along the sealing cavity 4, squeezing the gas in the sealing cavity 4 to form a compressed state. Since the power strip 1 and the housing 3 are in a stable snap-fit state at this time, the press valve 35 remains closed, and the compressed gas is stably stored in the sealing cavity 4 to provide emergency power for subsequent abnormal situations.
[0065] During normal use of cable 2, the pressure valve 35 is always closed, and the compressed gas in the sealed cavity 4 will not leak. This will not affect the tension and stability of cable 2, nor will it interfere with the connection between the power strip 1 and the housing 3, ensuring that the normal power supply and use function of the product are not affected.
[0066] When cable 2 experiences a short circuit, overload, or other abnormal fault, the moment the reset spring 31 pushes the power strip 1 away from the housing 3, it simultaneously triggers the opening of the press valve 35. The compressed gas in the sealed cavity 4 is then transported to the expansion pad 36 through the air outlet channel and pipeline, causing the expansion pad 36 to expand instantaneously. After the expansion pad 36 expands, the cable 2 at the location of the expansion pad 36 becomes difficult to bend, thereby further separating the power strip 1 from the housing 3. This prevents the power strip 1 and the housing 3 from coming into contact again after separation due to the installation position of the power strip 1, effectively widening the heat conduction distance, enhancing the heat insulation effect, and effectively preventing the possible spread of combustion from the housing 3 to the power strip 1, thus preventing the power strip 1 from igniting due to high temperature or burning of internal circuit components. At the same time, the expanded expansion pad 36 can support the power strip 1, keeping the power strip 1 and the housing 3 on the same horizontal line and maintaining a neat placement posture. This allows users to intuitively identify the fault location and quickly carry out emergency measures such as power outage and troubleshooting, improving fault response efficiency.
[0067] To facilitate automatic release of the locking mechanism between the power strip 1 and the housing 3, for example, such as... Figure 10 , Figure 13 As shown, the present invention also includes an adjustment hole 37 on the side of the housing 3 that communicates with the liquid storage chamber 22. An adjustment screw 38 is threadedly connected to the adjustment hole 37. A pressing plate 39 is fixedly connected to one end of the adjustment screw 38 located in the liquid storage chamber 22. An elastic film 40 is fixedly connected to the inner wall of the liquid storage chamber 22 on the four sides of the pressing plate 39.
[0068] When using the device, if it is necessary to separate the housing 3 from the power strip 1, first disconnect the terminal 6 of the cable 2 from the corresponding interface of the power strip 1 to cut off the power supply circuit. Then, rotate the adjusting screw 38. The adjusting screw 38 pushes the extrusion plate 39 into the liquid storage chamber 22. When the extrusion plate 39 moves, the elastic film 40 around it deforms synchronously, always keeping the liquid storage chamber 22 sealed. This ensures that the pressure generated by the extrusion can be fully applied to the thermally expanding fluid. The thermally expanding fluid in the liquid storage chamber 22 generates thrust after being extruded, which drives the output end of the telescopic cylinder 24 to extend synchronously. This, in turn, drives the arc-shaped retaining ring 25 and the arc-shaped limiting plate 26 to move outward until the arc-shaped limiting plate 26 completely disengages from the arc-shaped slot 29 on the pin 28 of the power strip 1. This automatically releases the locking between the power strip 1 and the housing 3, eliminating the need for manual prying or disassembly, thus ensuring the integrity of the components and their subsequent reusability.
[0069] After unlocking, the power strip 1 can be easily separated from the housing 3, making it convenient for users to inspect, maintain or replace the internal circuit of the power strip 1, the internal cables 2 of the housing 3 and other components, greatly reducing the difficulty of maintenance operations and improving the practicality and service life of the product.
[0070] In use, the pin 28 on the lower surface of the power strip 1 is aligned with the pin hole 27 on the upper surface of the housing 3 and inserted vertically. The lower end of the pin 28 is chamfered to press the arc-shaped limiting plate 26, so that the output end of the telescopic cylinder 24 extends to reserve a channel. When the arc-shaped slot 29 is aligned with the arc-shaped limiting plate 26, the telescopic cylinder 24 automatically resets and completes the locking. No additional tools are required, the connection operation is convenient, and the structural stability is ensured during use and carrying.
[0071] Connect the terminal 6 of cable 2 to the corresponding interface of power strip 1 to complete the circuit connection, solve the basic usage requirement of existing split power strip 1 that requires separate connection of cable 2, and ensure smooth power supply circuit;
[0072] When cable 2 is pulled out, the rotating drum 16 of the cleaning structure is rotated to move the conical cylinder 17 away from the elastic arc-shaped clamping plate 15, releasing the clamping limit on cable 2. Pulling the plug 7 causes cable 2 to extend outward. Cable 2 pulls the winding rod 9 to make the two sets of mounting plates 5 move towards each other against the elastic force of the compression spring 12. The limiting rod 13 ensures that the mounting plate 5 slides smoothly, ensuring that cable 2 is pulled out smoothly and avoiding damage to cable 2 due to uneven force. At the same time, when the mounting plate 5 moves, it causes the folding airbag 19 to unfold, and external gas is drawn through the one-way air inlet connector 20 to complete the gas storage, reserving power for subsequent cleaning.
[0073] After cable 2 is pulled out to the target length, the rotating drum 16 is rotated in the opposite direction. The conical drum 17 squeezes the arc-shaped clamping plate 15 to shrink towards the center and fits tightly with cable 2 to fix it, preventing cable 2 from sliding back or loosening during use. The compression spring 12 maintains the cable 2 with appropriate tension to avoid mess and ensure stable power supply to the electrical equipment.
[0074] After use, rotating the drum 16 releases the clamping of the arc-shaped clamping plate 15 on the cable 2, compressing the spring 12 to release its stored force and push the mounting plate 5 to reset, driving the winding rod 9 to pull the cable 2 back into the sealed cavity 4 in an orderly manner, so that the cable 2 can be quickly and neatly stored, avoiding knots and tangles, reducing the storage volume and improving portability; at the same time, the mounting plate 5 compresses and folds the airbag 19, and the gas is sprayed out along the circumference of the cable 2 through the air outlet 18 of the sleeve 14. The airflow dries the surface moisture of the cable 2 and blows out impurities, preventing insulation layer aging, conductor corrosion and poor port contact, and reducing the risk of short circuit and leakage.
[0075] When cable 2 experiences abnormally high temperatures due to short circuits or overloads, the thermally expanding fluid in the liquid storage chamber 22 expands due to heat, pushing the telescopic cylinder 24 to unlock the connection between the power strip 1 and the housing 3; the reset spring 31 releases its stored force and springs away from the power strip 1 through the compression ring 32, simultaneously triggering the press valve 35, and the compressed gas in the sealed chamber 4 drives the expansion pad 36 to expand, cutting off the heat conduction path and visually alerting the user with the pop-out action. At the same time, it widens the distance between the power strip 1 and the housing 3, strengthens heat insulation protection, prevents the spread of fire, and maintains the neat posture of the power strip 1 for rapid emergency response.
[0076] When maintenance is required, first disconnect the connection between terminal 6 and power strip 1, rotate the adjusting screw 38 on the side of housing 3, push the extrusion plate 39 to extrude the thermally expanding fluid, drive the telescopic cylinder 24 to unlock and separate power strip 1 from housing 3, and maintain the internal circuit, cable 2 and components. No manual prying and disassembly is required, achieving non-destructive separation, ensuring the integrity and reusability of components, reducing maintenance difficulty, and extending product life.
