Through the arrangement of the protection mechanism, when the push plate is pushed to the limit position, the limiting rod is clamped into the limiting clamping groove, the current access hole is locked, and other baffle plates remain closed. If the baffle plate is already locked, when the new baffle plate is pushed, the new limiting rod pushes the moving rod to make the original limiting rod disengage, and the original baffle plate is automatically reset under the action of the first elastic element, so that the baffle plate corresponding to the current pushed access hole is locked each time, thereby realizing single selection and forced locking of the access hole. Pressing the fixing block can make all the limiting rods disengage from the limiting clamping groove, and all the baffle plates are reset and closed under the action of the first elastic element. The application realizes selective isolation and forced locking of live components, eliminates the hidden danger of electric shock caused by accidental touching, improves the reliability in complex environments, and simultaneously simplifies maintenance operation and reduces cost.

Description

Technical Field

[0001] This invention relates to the field of distribution box technology, and more specifically, to a linkage protection type distribution box. Background Technology

[0002] Distribution boxes are electrical equipment characterized by their small size, easy installation, special technical performance, fixed location, unique configuration functions, no site restrictions, wide application, stable and reliable operation, high space utilization, small footprint, and environmental benefits.

[0003] Chinese Patent Application No. CN202510301746.4 discloses a wall-mounted distribution box and its installation method, relating to the field of distribution box technology. The box includes a main body with a hinged door on the front. First heat dissipation grooves are formed on both side walls of the main body, and a first inner groove is formed on the back of the top plate. Multiple fixed posts and first springs are evenly and equidistantly fixed to the inner wall of the first inner groove. Each first spring is sleeved on each fixed post. A connecting rod is slidably installed on each fixed post, and a diversion plate is fixedly installed at the upper end of each connecting rod. The multiple diversion plates are triangular in shape. Sliding strips are fixedly installed on the two connecting rods at both ends. By designing the device with an adjustable installation method, cumbersome measurement and positioning are eliminated, greatly shortening installation time, improving work efficiency, and more evenly distributing the weight of the distribution box, enhancing overall stability and reducing safety hazards caused by shaking or displacement.

[0004] Although the aforementioned invention can shorten installation time and enhance stability, existing distribution boxes mostly adopt a single door independent protection design. Due to the lack of a precise linkage mechanism between the door and the internal live components, it is impossible to isolate the live components in time. It also lacks a forced locking function for accidental operation and has poor maintenance convenience. As a result, the internal live components are directly exposed when the door is opened, which can easily lead to accidental electric shock safety accidents, reduce the reliability of the distribution box in complex environments, and increase maintenance costs and operational complexity.

[0005] This invention provides a linkage protection type distribution box, which aims to solve the problem that existing distribution boxes use a single door for protection, lack linkage isolation and misoperation locking functions, and expose live parts when the door is opened, which can easily lead to electric shock accidents. Summary of the Invention

[0006] The purpose of this invention is to provide a linkage protection type distribution box to solve the problem mentioned in the background art that the existing distribution boxes use a single door for protection, lack linkage isolation and misoperation interlocking functions, and expose live parts when the door is opened, which can easily lead to electric shock accidents.

[0007] To achieve the above objectives, the present invention provides the following technical solution: a linkage protection type distribution box, comprising a box body, a door hinged to the box body, and electrical components disposed within the box body, and further comprising: A protective mechanism is provided between the electrical component and the cabinet door to achieve selective isolation and forced locking of live parts; A linkage triggering mechanism is provided, which connects the protective mechanism and the housing. It provides elastic buffering for the protective mechanism and drives the protective mechanism to automatically reset to a fully isolated state when it is subjected to an external impact or when the housing door is closed.

[0008] Preferably, the protective mechanism includes an insulating guard plate, the insulating guard plate having an inspection port corresponding to the position of each electrical component, the outer side of the insulating guard plate having a guide groove corresponding to the position of each inspection port, and a baffle being slidably connected inside each guide groove.

[0009] Preferably, the baffle is made of transparent material, and a push plate is fixedly connected to the outer side of each baffle; Each of the baffles has a first support plate fixedly connected to its inner side, and the insulating protective plate has a second support plate fixedly connected to its inner side in the same number and corresponding position as the baffles. Each of the first support plates and the corresponding second support plate is connected by a first elastic element.

[0010] Preferably, an installation box is fixedly connected to the outer side of the insulating protective plate, and a movable groove is opened inside the installation box. A connecting groove connected to the movable groove is opened at the corresponding position of each of the baffles in the installation box. An extension member that can be inserted into the corresponding connecting groove is fixedly connected to the side of each baffle near the installation box.

[0011] Preferably, each of the extensions is fixedly connected to a limiting rod on the side near the door, and a transversely penetrating moving rod is slidably connected inside the moving groove. Multiple limiting members are fixedly connected to the moving rod, and the number of limiting members is the same as that of the extensions and their positions correspond to each other.

[0012] Preferably, the limiting member is provided with a wedge-shaped guide and a limiting groove; A fixing block is fixedly connected to one end of the movable rod extending out of the mounting box, and a second elastic element sleeved on the movable rod is connected between the fixing block and the mounting box on the side of the fixing block near the mounting box. A circular guide portion is provided on the side of the fixing block away from the mounting box.

[0013] Preferably, the linkage triggering mechanism includes multiple telescopic cylinders, one end of each of the multiple telescopic cylinders is fixedly connected to the housing, the other end of each telescopic cylinder is provided with a telescopic groove, and a telescopic rod is slidably connected inside each telescopic groove.

[0014] Preferably, a third elastic element is connected between one end of each telescopic rod located inside the telescopic groove and the bottom of the corresponding telescopic groove, and the other end of each telescopic rod is fixedly connected to the insulating protective plate.

[0015] Preferably, the insulating protective plate has a slot at the position corresponding to the fixing block, and a pressing rod is fixedly connected to the inner cavity of the box at the position corresponding to the slot; The end of the extrusion rod near the fixed block is provided with a wedge-shaped extrusion part that can cooperate with the circular guide part.

[0016] Preferably, a support block is fixedly connected to the inner side of the box door at a position corresponding to the fixing block, and a circular pressing part is provided at the end of the support block away from the box door, which can cooperate with the circular guide part.

[0017] The technical effects and advantages of this invention are as follows: 1. This invention, through the setting of a protective mechanism, uses an insulating protective plate to isolate electrical components from the cabinet door, and a transparent baffle to close the inspection port for observation. After pushing the push plate, the baffle drives the limit rod through the connecting groove into the moving groove, pushing the limit member to compress the moving rod into the second elastic member. After reaching the position, the second elastic member pushes back to lock the limit rod into the limit slot, locking the current inspection port, while other baffles remain closed. If a baffle is already locked, when a new baffle is pushed, the new limit rod pushes the moving rod to disengage the original limit rod, and the original baffle automatically resets under the action of the first elastic member, ensuring that only the baffle corresponding to the currently pushed inspection port is locked each time, thereby realizing single-selection and forced locking of the inspection port. Pressing the fixing block can disengage all limit rods from the limit slots, and all baffles reset and close under the action of the first elastic member. This invention achieves selective isolation and forced locking of live parts, eliminates the risk of electric shock due to accidental contact, improves reliability in complex environments, simplifies maintenance operations, and reduces costs. 2. This invention, through the linkage triggering mechanism, achieves the following: Firstly, when a person impacts the insulating guard plate, the telescopic rod compresses the third elastic element to absorb the impact energy. Simultaneously, the insulating guard plate moves backward, causing the squeezing rod to extend relative to it. Its wedge-shaped squeezing part pushes the circular guide part on the fixed block, driving the moving rod to compress the second elastic element. The displacement of the limiting part causes the locked limiting rod to disengage from the limiting slot. Each baffle, under the action of the first elastic element, resets and closes the inspection port, achieving impact buffering and forced isolation of live parts. Secondly, the support block inside the door has a circular squeezing part. When the door is closed, the circular squeezing part also squeezes the circular guide part, triggering the same reset action, ensuring that the inspection port automatically closes. This provides buffer protection and closes the exposed live area when a person falls. At the same time, the closing action automatically eliminates the safety hazard of an unclosed inspection port, improving maintenance safety and operational fault tolerance.

[0031] 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.

[0032] Existing distribution boxes mostly adopt a single door design with independent protection. Due to the lack of a precise linkage mechanism between the door and the internal live parts, it is impossible to isolate the live parts in time. It also lacks a forced locking function for accidental operation and has poor maintenance convenience. As a result, the internal live parts are directly exposed when the door is opened, which can easily lead to accidental electric shock accidents. This reduces the reliability of the distribution box in complex environments and increases maintenance costs and operational complexity.

[0033] Example 1 refer to Figures 1 to 12 An embodiment of the present invention provides a linkage protection type distribution box, including a box body 1, a box door 11, and a protection mechanism 2 disposed between the two. The box door 11 is hinged to the box body 1. Multiple electrical components 12 are installed in the inner cavity of the box body 1. The protection mechanism 2 is elastically connected to the inner wall of the box body 1 through a linkage triggering mechanism 3 to form an inner isolation barrier with axial buffering capability.

[0034] refer to Figure 2 and Figure 3 The protective mechanism 2 includes an insulating guard plate 21. Each position of the insulating guard plate 21 is provided with an inspection port 22. Each position of the inspection port 22 is provided with a guide groove 23 on the outside of the insulating guard plate 21. A transparent baffle 24 is slidably connected inside each guide groove 23. A push plate 25 is fixedly connected to the outside of the baffle 24 to facilitate manual operation.

[0035] refer to Figure 6Each baffle 24 has a first support plate 26 fixedly connected to its inner side, and the insulating protective plate 21 has a second support plate 27 with the same number and position as the baffle 24 fixedly connected to its inner side. Each first support plate 26 and the corresponding second support plate 27 are connected by a first elastic element 28. When the baffle 24 is in the closed access port 22 position, the first elastic element 28 is in a slightly compressed state. When the baffle 24 is opened, the first elastic element 28 is further compressed, thereby providing the baffle 24 with a preload force to reset in the closing direction.

[0036] refer to Figure 8 and Figure 9 An installation box 29 is fixedly connected to the outer side of the insulating protective plate 21. The installation box 29 has a moving groove 210 inside. The installation box 29 and each baffle 24 have a corresponding connecting groove 211 that communicates with the moving groove 210. Each baffle 24 has an extension 212 that can be inserted into the corresponding connecting groove 211 fixedly connected to the side near the installation box 29. Each extension 212 has a limit rod 213 fixedly connected to the side near the door 11.

[0037] refer to Figure 9 and Figure 10 The movable groove 210 has a horizontally penetrating movable rod 215 slidably connected inside. Multiple limiting members 214 are fixedly connected to the movable rod 215. The number of limiting members 214 is the same as that of the extension members 212 and their positions are corresponding. The limiting members 214 are provided with wedge-shaped guide parts 216 and limiting slots 217.

[0038] The movable rod 215 can be laterally limited and slid inside the mounting box 29 via the mounting guide rail, ensuring the smooth lateral sliding of the movable rod 215.

[0039] refer to Figure 9 and Figure 10 A fixing block 218 is fixedly connected to one end of the moving rod 215 extending out of the mounting box 29. A second elastic element 219 sleeved on the moving rod 215 is connected between the fixing block 218 and the mounting box 29 on the side near the mounting box 29.

[0040] When any baffle 24 is pushed to the opening limit, the limiting rod 213 contacts and slides along the wedge-shaped guide 216 on the limiting member 214, thereby pressing the moving rod 215 to move laterally. After the limiting rod 213 enters the limiting slot 217, the moving rod 215 rebounds under the action of the second elastic member 219, completing the locking.

[0041] During normal operation, all baffles 24 close the inspection port 22, and the insulating protective plate 21 isolates the electrical components 12 from the box door 11. After the operator opens the box door 11, he / she can observe the status of the internal components through the transparent baffle 24 without directly contacting the live parts, thus avoiding the risk of accidental electric shock.

[0042] When a certain electrical component 12 needs to be repaired, the corresponding push plate 25 is pushed, which drives the baffle 24 to move along the guide groove 23 toward the mounting box 29. The extension 212 and the limiting rod 213 on the baffle 24 enter the moving groove 210 through the connecting groove 211. When the limiting rod 213 contacts the wedge-shaped guide part 216 of the limiting member 214, the limiting member 214 is pushed to compress the moving rod 215 and the second elastic member 219. When the baffle 24 moves to the limit position, the inspection port 22 is fully opened, and the limiting rod 213 corresponds to the position of the limiting slot 217. At this time, the second elastic member 219 can push the moving rod 215 back and lock the limiting rod 213 into the limiting slot 217. At this time, the inspection port 22 remains open, and the operator can safely repair the corresponding electrical component 12. The other baffles 24 that have not been pushed are still closed, and the live parts in the unrepaired area are still isolated to prevent all live parts from being directly exposed.

[0043] If a baffle 24 is already locked (a certain access port 22 is open), and another baffle 24 is pushed, the limiting rod 213 on the new baffle 24 will press the wedge-shaped guide portion 216 on the corresponding limiting member 214, thereby pushing the corresponding limiting member 214 and the moving rod 215 to compress the second elastic member 219 again. During this process, the limiting rod 213, which was originally stuck in the limiting slot 217, will be dislodged due to the displacement of the moving rod 215 (that is, the limiting slot 217 moves axially with the moving rod 215, deviating from the original position of the limiting rod 213, causing the limiting rod 213 to lose its constraint). The baffle 24 will automatically rebound and close the corresponding access port 22 under the action of the first elastic member 28, while the new baffle 24 will continue to move to the limit position and be locked, thereby ensuring that only one set of baffles 24 can be locked at a time, preventing multiple sets of access ports 22 from opening at the same time, which could cause operational chaos or safety risks.

[0044] It should be noted that if multiple inspection ports 22 are to be opened at the same time, multiple push plates 25 must be pushed simultaneously and synchronously so that each limit rod 213 contacts and pushes the corresponding limit member 214 at the same time. After all the baffles 24 have reached their limit positions, the moving rod 215 can be reset to lock multiple baffles 24 at the same time.

[0045] After all maintenance is completed, press the fixing block 218 to compress the second elastic element 219 with the moving rod 215 and drive all the limiting elements 214 to move, so that all the locked limiting rods 213 are disengaged from the limiting slots 217. All the baffles 24 automatically reset and close the maintenance port 22 under the action of the corresponding first elastic element 28. After releasing the fixing block 218, the second elastic element 219 pushes the moving rod 215 and the limiting elements 214 back to their original positions, waiting for the next operation.

[0046] In summary, through the setting of the protective mechanism 2, the electrical component 12 is isolated from the box door 11 by the insulating protective plate 21, and the transparent baffle 24 closes the inspection port 22 for observation. After pushing the push plate 25, the baffle 24 drives the limiting rod 213 to enter the moving groove 210 through the connecting groove 211. Pushing the limiting member 214 causes the moving rod 215 to compress the second elastic member 219. After reaching the position, the second elastic member 219 pushes back to lock the limiting rod 213 into the limiting slot 217, locking the inspection port 22. Other baffles 24 remain closed. Multiple push plates 25 can be pushed simultaneously to open multiple inspection ports 22 synchronously. If baffles are already in place... When the new baffle 24 is locked, the new limit rod 213 pushes the moving rod 215 to disengage the original limit rod 213. The original baffle 24 automatically resets under the action of the first elastic element 28, ensuring that only the currently pushed baffle 24 is locked each time. Pressing the fixing block 218 can disengage all limit rods 213 from the limit slot 217, and all baffles 24 reset and close under the action of the first elastic element 28. This achieves selective isolation and forced locking of live parts, eliminates the risk of electric shock caused by accidental contact, improves reliability in complex environments, simplifies maintenance operations, and reduces costs.

[0047] Example 2 During actual maintenance of the distribution box, if the operator accidentally hits the insulating guard plate 21 or forgets to close the inspection port 22 and closes the door directly, the opened inspection port 22 cannot automatically reset and close, resulting in the continuous exposure of live parts and posing a serious risk of electric shock. Therefore, this embodiment improves the device described in the above embodiment.

[0048] refer to Figures 3 to 12 The linkage triggering mechanism 3 includes multiple telescopic cylinders 31. One end of each telescopic cylinder 31 is fixedly connected to the housing 1 and is evenly distributed in the inner cavity of the housing 1. The other end of each telescopic cylinder 31 is provided with a telescopic groove 32. A telescopic rod 33 is slidably connected inside each telescopic groove 32. A third elastic element 310 is connected between one end of each telescopic rod 33 inside the telescopic groove 32 and the bottom of the corresponding telescopic groove 32. The other end of each telescopic rod 33 is fixedly connected to the insulating protective plate 21 to support the insulating protective plate 21.

[0049] Under normal conditions, the elastic force of the third elastic element 310 causes the telescopic rod 33 to extend out of the telescopic groove 32, pushing the insulating protective plate 21 away from the inner wall of the box 1, and placing it in a naturally extended position. When the insulating protective plate 21 is impacted by an external force, the telescopic rod 33 compresses the third elastic element 310 and slides into the telescopic groove 32. After the external force disappears, the elastic force of the third elastic element 310 drives the insulating protective plate 21 to automatically return to the naturally extended position.

[0050] refer to Figures 4 to 6The insulating protective plate 21 has a slot 34 at the corresponding position of the fixing block 218. The inner cavity of the box 1 is fixedly connected to the slot 34 at the corresponding position. The fixing block 218 is provided with a circular guide part 36 on the side away from the mounting box 29. The end of the pressing rod 35 near the fixing block 218 is provided with a wedge-shaped pressing part 37 that can cooperate with the circular guide part 36.

[0051] Under normal conditions, when the insulating plate 21 is in its naturally extended position (when the third elastic member 310 is not compressed), a predetermined gap is maintained between the wedge-shaped extrusion part 37 at the end of the extrusion rod 35 and the circular guide part 36 on the fixing block 218. During normal maintenance, if the operator touches the insulating plate 21 slightly, it will not trigger the movement of the moving rod 215. Only when the insulating plate 21 is subjected to a large external force sufficient to compress the third elastic element 310 (such as a human body impact), the wedge-shaped extrusion part 37 can contact and push the circular guide part 36, thereby driving the moving rod 215 to compress the second elastic element 219 and achieve the forced reset of the baffle 24.

[0052] refer to Figure 4 and Figure 5 A support block 38 is fixedly connected to the inner side of the box door 11 at the position corresponding to the fixing block 218. A circular pressing part 39 is provided at the end of the support block 38 away from the box door 11.

[0053] During actual maintenance work, when the staff accidentally hits the insulating guard plate 21 during the maintenance process, the insulating guard plate 21 pushes the telescopic rod 33 to slide into the telescopic groove 32, compresses the third elastic element 310, and causes the entire insulating guard plate 21 to move towards the inside of the box 1. At this time, the extrusion rod 35, which was originally located in the slot 34, extends out relative to the slot 34. The wedge-shaped extrusion part 37 at its end contacts the circular guide part 36 on the fixing block 218 and generates extrusion, pushing the fixing block 218 to drive the moving rod 215 to compress the second elastic member 219. During this process, all the limiting members 214 on the moving rod 215 are displaced, causing the limiting rods 213 that have been locked into the limiting slots 217 to disengage. All the baffles 24 automatically reset along the guide grooves 23 under the action of the corresponding first elastic members 28, closing all the inspection ports 22. On the one hand, the elastic buffer of the linkage triggering mechanism 3 can reduce the risk of human body impacting the rigid structure, and on the other hand, it can forcibly close all the opened inspection ports 22, re-isolate the live parts behind the insulating guard plate 21, effectively prevent the electric shock accident caused by the limbs of the personnel accidentally touching the exposed electrical components 12 after falling to the ground, and significantly improve the active and passive safety of the maintenance operation.

[0054] When the staff forgets to close the open inspection port 22 after the maintenance is completed and closes the box door 11 directly, the support block 38 on the inside of the box door 11 rotates with the box door 11, and the circular pressing part 39 at its end directly presses the circular guide part 36 on the fixed block 218 (at this time, there is no need to rely on the insulating guard plate 21 to move), directly pushing the fixed block 218 and the moving rod 215 to compress the second elastic member 219, so that all the limiting members 214 are displaced accordingly; At this time, the locked limit rod 213 disengages from the limit slot 217, and each baffle 24 automatically resets and closes the inspection port 22 under the action of the first elastic element 28, ensuring that all live parts are isolated by the insulating guard plate 21 after the box door 11 is closed. This eliminates the safety hazard of the inspection port 22 not being closed due to operational negligence, and ensures that the operator will not directly face the exposed live parts when the box is opened next time. At the same time, it saves the step of manually checking or resetting each part, reducing the complexity of maintenance operations.

[0055] In summary, through the linkage triggering mechanism 3, on the one hand, when a person impacts the insulating guard plate 21, the telescopic rod 33 compresses the third elastic element 310 to absorb the impact energy. At the same time, the insulating guard plate 21 moves backward, causing the squeezing rod 35 to extend relative to it. Its wedge-shaped squeezing part 37 pushes the circular guide part 36 on the fixed block 218, causing the moving rod 215 to compress the second elastic element 219. The displacement of the limiting member 214 causes the locked limiting rod 213 to disengage from the limiting slot 217. Each baffle 24 resets and closes the inspection port 22 under the action of the first elastic element 28, thus achieving impact buffering and forced isolation of live parts. On the other hand, the support block 38 on the inner side of the box door 11 has a circular squeezing part 39. When the door is closed, the circular squeezing part 39 also squeezes the circular guide part 36, triggering the same reset action to ensure that the inspection port 22 closes automatically. This provides buffer protection and closes the exposed live area when a person falls. At the same time, the closing action automatically eliminates the safety hazard of the inspection port 22 not being closed, improving maintenance safety and operational fault tolerance.

[0056] In conclusion, the above description is only a preferred embodiment of the present invention and is not intended to limit the present invention. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of the present invention should be included within the protection scope of the present invention.
