Description

Technical Field

[0001] This invention relates to the field of cable branch box technology, specifically to a cable branch box with safety protection and optimized layout. Background Technology

[0002] In the existing field of cable distribution box technology, traditional cable distribution boxes have fixed internal operating space, making it difficult to flexibly adjust according to actual needs. This causes inconvenience for operators in operating and maintaining equipment in different locations, resulting in low space utilization. Furthermore, the lack of a dedicated safety operating platform for operators poses safety hazards during maintenance and other operations. Regarding heat dissipation, most cable distribution boxes have poor heat dissipation performance, failing to quickly and effectively dissipate the heat generated by the internal equipment. This leads to the equipment operating in a high-temperature environment for extended periods, shortening its lifespan. Additionally, the lack of a filter at the air inlet allows dust and debris to easily enter the box, damaging the equipment and affecting its reliability and stability. Moreover, the box's sealing performance is insufficient, allowing external dust and moisture to easily enter, adversely affecting the equipment's operating environment. Furthermore, the simple door locking structure makes the cabinet door prone to automatically closing during maintenance, posing a safety hazard. The unlocking method is also inconvenient, especially in maintenance scenarios requiring frequent door opening and closing, resulting in low operational efficiency. Summary of the Invention

[0003] The purpose of this invention is to provide a cable branch box with safety protection and optimized layout to solve the problems mentioned in the background art.

[0004] To achieve the above objectives, the present invention provides the following technical solution: a cable branch box with safety protection and optimized layout, comprising a box body, an internal lifting assembly, the lifting assembly comprising a first column and a second column, both fixed inside the box body, a limiting groove being formed inside the first column, a lead screw being rotatably mounted inside the limiting groove, a lifting motor being fixed above the first column, the output shaft of the lifting motor being fixedly connected to the lead screw, a sliding block 1 being slidably mounted on the first column, a moving block being fixed on the sliding block 1, the moving block being threadedly connected to the lead screw, and the moving block being slidably mounted inside the limiting groove, a sliding block 2 being slidably mounted on the second column, a connecting plate being fixed on both the sliding block 1 and the sliding block 2, a baffle being fixed below the two connecting plates, a sealing assembly being provided on the box body, and a locking assembly being provided on the sealing assembly.

[0005] Two fixing blocks are fixed above the baffle, and a rotating rod is rotatably arranged between the two fixing blocks. Two support plates are fixed above the rotating rod, and a pedal is detachably arranged above the two support plates.

[0006] With the above structure, the first pedal is made of insulating material, and a rotating rod is rotatably mounted between the two fixed blocks above the baffle. The first pedal is detachably mounted on the two support plates above the rotating rod. When the first pedal is needed, it can be mounted on the support plates, allowing operators to stand on the first pedal to operate or maintain the equipment inside the enclosure.

[0007] The box is equipped with an installation frame inside. A lower plate and an upper plate are fixed inside the box. An inlet fan is located below the lower plate, and an outlet fan is located above the upper plate. A top plate is installed at an angle on the top of the box, and a base is installed at the bottom of the box. An air inlet is located on the side of the base, and a filter box is installed on the air inlet.

[0008] With the above structure, the intake fan is located below the lower plate, and the exhaust fan is located above the upper plate. When the intake fan is working, it draws outside air into the cabinet through the air inlet on the side of the base. After the air passes through the filter box, it enters the cabinet, carrying away the heat generated by the equipment inside. Then, the hot air is exhausted from the top of the cabinet by the exhaust fan, forming an air circulation to dissipate heat from the equipment inside the cabinet. Through the synergistic action of the intake and exhaust fans, a forced air circulation is formed, which can quickly and effectively dissipate the heat inside the cabinet, ensuring that the equipment operates in a suitable temperature environment and extending the service life of the equipment. The filter box at the air inlet can filter the air entering the cabinet to prevent dust, debris, etc. from entering the cabinet and causing damage to the equipment, thereby improving the reliability and stability of the equipment. The top plate is inclined at the top of the cabinet, and the base is located at the bottom of the cabinet. The inclined design of the top plate allows rainwater and other liquids to slide off naturally, preventing water accumulation from corroding the cabinet. The base provides stable support for the cabinet, and the air inlet on the side of the base provides an air intake channel for the heat dissipation components.

[0009] The sealing assembly includes a sealing frame, which is fixed to the housing. A sealing gasket is provided inside the sealing frame, and a door panel is hinged inside the sealing frame. A handle is provided on the door panel.

[0010] With the above structure, the sealing frame is fixed to the enclosure, and a sealing gasket is installed inside. The door panel is hinged inside the sealing frame, and the handle facilitates the operator's opening and closing of the door panel. When the door panel is closed, the door panel and the sealing gasket inside the sealing frame are in close contact, forming a sealed structure to prevent external dust, moisture, etc. from entering the enclosure. The use of the sealing gasket effectively improves the sealing performance between the door panel and the sealing frame, and can effectively block external impurities and moisture from entering the enclosure, protecting the internal equipment from the influence of the external environment. The handle makes it convenient for the operator to open and close the door panel, improving the ease of operation.

[0011] The locking assembly includes a fixed cylinder with two fixed blocks 2 fixed on it. Both fixed blocks 2 are fixed to the door panel. A sliding rod 2 is slidably arranged inside the fixed cylinder. A rubber pad is fixed to one end of the sliding rod 2, and a moving cylinder is fixed to the other end of the sliding rod 2. A first spring is sleeved on the sliding rod 2. Several limiting teeth are arranged inside the fixed cylinder.

[0012] With the above structure, the fixed cylinder is securely mounted on the door panel via two fixing blocks, providing a basic support structure for the entire locking assembly. The sliding rod can slide freely inside the fixed cylinder. One end of the sliding rod is connected to a rubber pad, and the other end is connected to the moving cylinder. A first spring is sleeved on the sliding rod. In its natural state, the elastic force of the first spring will cause the sliding rod to tend to extend outward from the fixed cylinder. Several limiting teeth set inside the fixed cylinder can restrict and position the movement of the sliding rod during its sliding process. When the door panel is closed, the rubber pad will first contact the housing or other corresponding contact surfaces. As the door panel continues to close, the sliding rod will slide inward from the fixed cylinder, compressing the first spring. The elastic force of the first spring will then react on the sliding rod. The rubber pad fits tightly against the contact surface, while the limiting teeth prevent the sliding rod from sliding freely when no external force is applied. The two fixing blocks firmly fix the fixing cylinder to the door panel, ensuring the stability of the locking assembly on the door panel. This prevents the entire locking structure from loosening or shifting during operation, providing a reliable foundation for the locking function. The presence of the first spring provides a certain buffering effect when the rubber pad contacts the contact surface, adapting to contact surfaces with different flatness and ensuring that the rubber pad always fits tightly against the contact surface, improving the sealing and stability of the lock. The limiting teeth initially restrict the movement of the sliding rod, preventing the door panel from opening automatically under slight external force, thus enhancing the reliability of the door panel locking.

[0013] The locking assembly also includes a second pedal, a first sliding rod rotatably disposed below the second pedal, the first sliding rod slidably disposed on the moving cylinder, a locking block fixed to the end of the first sliding rod, the locking block slidably disposed inside the moving cylinder, an installation cylinder slidably disposed inside the moving cylinder, a moving rod fixed below the locking block, an annular groove opened at the end of the moving rod, the moving rod slidably disposed inside the installation cylinder, a second spring sleeved on the moving rod, the second spring being located between the locking block and the installation cylinder, a plurality of limiting holes opened inside the moving cylinder, and a limiting steel ball being disposed inside each of the plurality of limiting holes.

[0014] With the above structure, a sliding rod is rotatably mounted below the second pedal. The sliding rod is slidably mounted on the moving cylinder. When the door panel needs to be unlocked, the operator steps on the second pedal, which drives the sliding rod to slide on the moving cylinder. The locking block at the end of the sliding rod also slides inside the moving cylinder. A moving rod is fixed below the locking block. An annular groove at the end of the moving rod provides a certain amount of space for its sliding within the mounting cylinder. The moving rod is slidably mounted inside the mounting cylinder, and a second spring is sleeved on the moving rod. The second spring is located between the locking block and the mounting cylinder. During the sliding of the locking block, it will compress or stretch the second spring. The mounting cylinder is slidably mounted inside the moving cylinder. Several limiting holes inside the moving cylinder contain limiting steel balls. When the door panel is locked, the limiting steel balls are in a specific position, cooperating with the locking block and other related structures to restrict the movement of the moving cylinder, thereby ensuring the locked state of the door panel. When the second pedal is stepped on, the locking block moves, driving the moving rod to slide within the mounting cylinder. The sliding cylinder slides inside, compressing the second spring. As the locking block moves, the position of the limiting steel ball within the limiting hole changes. When the locking block moves to a certain position, the limiting steel ball no longer restricts the moving cylinder, allowing it to move freely and unlocking the door panel. When the door panel needs to be locked again, releasing the second pedal causes the spring force of the second and first springs to return all components to their locked positions, and the limiting steel ball resumes its restrictive function. The second pedal allows operators to easily initiate the unlocking process with a simple step, eliminating the need for additional tools and improving operational convenience, especially suitable for scenarios requiring frequent opening and closing of the door panel, such as maintenance. The cooperation of the limiting steel ball, limiting hole, and locking block enables precise control of the moving cylinder's movement, thus accurately locking and unlocking the door panel. When locked, the door panel can be fixed at any angle, preventing the cabinet door from automatically closing during maintenance and effectively eliminating safety hazards.

[0015] Compared with the prior art, the beneficial effects of the present invention are: A cable branch box with safety protection and optimized layout features a lifting assembly that allows for flexible adjustment of the internal operating space, along with a detachable insulated pedal, enhancing operational convenience and safety. A heat dissipation assembly creates forced air circulation, effectively dissipating heat and preventing dust and debris from entering, extending equipment lifespan and improving reliability. A sealing assembly effectively blocks external dust and moisture, providing a good operating environment. A locking assembly enables precise locking and unlocking of the door panel, fixing it at any angle to prevent automatic closure and eliminate safety hazards. The unlocking method is convenient and quick, comprehensively improving the performance and safety of the cable branch box. Attached Figure Description

[0018] 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.

[0019] like Figures 1-11As shown, the present invention provides a technical solution: a cable branch box with safety protection and optimized layout, including a box body 4. A lifting assembly is provided inside the box body 4. The lifting assembly includes a first column 12 and a second column 21. The first column 12 and the second column 21 are both fixed inside the box body 4. A limiting groove 16 is opened inside the first column 12. A lead screw 15 is rotatably arranged inside the limiting groove 16. A lifting motor 11 is fixed above the first column 12. The output shaft of the lifting motor 11 is fixedly connected to the lead screw 15. A sliding block 17 is slidably arranged on the first column 12. A moving block is fixed on the sliding block 17. The moving block is threadedly connected to the lead screw 15 and is slidably arranged inside the limiting groove 16. A sliding block 26 is slidably arranged on the second column 21. A connecting plate 18 is fixed on both the sliding block 17 and the sliding block 26. A baffle 19 is fixed below the two connecting plates 18. A sealing assembly is provided on the box body 4. A locking assembly is provided on the sealing assembly.

[0020] Two fixing blocks 20 are fixed above the baffle 19, and a rotating rod 35 is rotatably mounted between the two fixing blocks 20. Two support plates 8 are fixed above the rotating rod 35, and a foot pedal 7 is detachably mounted above the two support plates 8. The foot pedal 7 is made of insulating material. When the foot pedal 7 is needed, it can be installed on the support plates 8, allowing operators to stand on it to operate or maintain the equipment inside the enclosure 4.

[0021] The enclosure 4 has a mounting bracket 9 inside. A lower plate 13 and an upper plate 14 are fixed inside the enclosure 4. An intake fan is located below the lower plate 13, and an exhaust fan is located above the upper plate 14. A top plate 5 is inclinedly installed on the top of the enclosure 4. A base 10 is located at the bottom of the enclosure 4, and an air inlet is located on the side of the base 10, with a filter box installed on the inlet. The intake fan is located below the lower plate 13, and the exhaust fan is located above the upper plate 14. When the intake fan is working, it draws outside air into the enclosure 4 through the air inlet on the side of the base 10. After being filtered by the filter box, the air enters the enclosure 4, carrying away the heat generated by the equipment inside. Then, the hot air is exhausted from the top of the enclosure 4 by the exhaust fan, forming an air circulation system and achieving air circulation within the enclosure 4. The heat dissipation of the equipment is achieved through the coordinated action of the intake and exhaust fans, forming a forced air circulation that can quickly and effectively dissipate heat from inside the housing 4, ensuring that the equipment operates in a suitable temperature environment and extending its service life. The filter box installed at the air inlet can filter the air entering the housing 4, preventing dust, debris, etc. from entering the housing 4 and avoiding damage to the equipment, thus improving the reliability and stability of the equipment. A top plate 5 is inclinedly installed on the top of the housing 4, and a base 10 is located at the bottom of the housing 4. The inclined design of the top plate 5 allows rainwater and other liquids to slide off naturally, preventing water accumulation from corroding the housing 4. The base 10 provides stable support for the housing 4, and the air inlet on the side of the base 10 provides an air intake channel for the heat dissipation components.

[0022] The sealing assembly includes a sealing frame 6, which is fixed to the housing 4. A sealing gasket is installed inside the sealing frame 6, and a door panel 1 is hinged to the inside of the sealing frame 6. A handle 2 is installed on the door panel 1. The sealing frame 6 is fixed to the housing 4, and the door panel 1 is hinged inside the sealing frame 6. The handle 2 facilitates the operator in opening and closing the door panel 1. When the door panel 1 is closed, it comes into close contact with the sealing gasket inside the sealing frame 6, forming a sealed structure to prevent external dust, moisture, etc., from entering the housing 4. The use of the sealing gasket effectively improves the sealing performance between the door panel 1 and the sealing frame 6, effectively blocking external impurities and moisture from entering the housing 4 and protecting the internal equipment from the influence of the external environment. The handle 2 facilitates the operator in opening and closing the door panel 1, improving operational convenience.

[0023] The locking assembly includes a fixed cylinder 22, on which two fixing blocks 25 are fixed. Both fixing blocks 25 are fixed to the door panel 1. A sliding rod 38 is slidably arranged inside the fixed cylinder 22. A rubber pad 26 is fixed to one end of the sliding rod 38, and a moving cylinder 27 is fixed to the other end of the sliding rod 38. A first spring 28 is sleeved on the sliding rod 38. Several limiting teeth 3 are provided inside the fixed cylinder 22. The fixed cylinder 22 is securely installed on the door panel 1 by the two fixing blocks 25, forming the entire locking assembly. A basic support structure is provided, allowing the sliding rod 38 to slide freely inside the fixed cylinder 22. One end of the sliding rod is connected to a rubber pad 26, and the other end is connected to a movable cylinder 27. A first spring 28 is fitted onto the sliding rod 38. In its natural state, the elastic force of the first spring 28 causes the sliding rod 38 to tend to extend outward from the fixed cylinder 22. Several limiting teeth 3 provided inside the fixed cylinder 22 can restrict and position the movement of the sliding rod 38 during its sliding process. When the door panel 1 is closed, the rubber pad 26... The pad 26 will first contact the housing 4 or other corresponding contact surfaces. As the door panel 1 continues to close, the sliding rod 38 will slide into the fixed cylinder 22, compressing the first spring 28. The elastic force of the first spring 28 will react on the sliding rod 38, making the rubber pad 26 tightly fit the contact surface. At the same time, the limiting tooth 3 can prevent the sliding rod 38 from sliding freely when there is no external force. The two fixing blocks 25 firmly fix the fixed cylinder 22 to the door panel 1, ensuring the stability of the locking assembly on the door panel 1. This ensures that the entire locking structure will not loosen or shift during operation, providing a reliable foundation for the locking function. The presence of the first spring 28 gives the rubber pad 26 a certain buffering effect when it contacts the contact surface, which can adapt to contact surfaces with different flatness and ensure that the rubber pad 26 always fits tightly with the contact surface, improving the sealing and stability of the lock. The setting of the limiting tooth 3 initially restricts the movement of the sliding rod 38, preventing the door panel 1 from opening automatically under slight external force to a certain extent, and enhancing the reliability of the door panel 1 locking.

[0024] The locking assembly also includes a second pedal 24. A sliding rod 23 is rotatably mounted below the second pedal 24. The sliding rod 23 is slidably mounted on a movable cylinder 27. A locking block 29 is fixed to the end of the sliding rod 23. The locking block 29 is slidably mounted inside the movable cylinder 27. An mounting cylinder 32 is slidably mounted inside the movable cylinder 27. A moving rod 30 is fixed below the locking block 29. An annular groove 34 is formed at the end of the moving rod 30. The moving rod 30 is slidably mounted inside the mounting cylinder 32. A second spring 31 is sleeved on the moving rod 30, located between the locking block 29 and the mounting cylinder 32. Several limiting holes 33 are formed inside the movable cylinder 27, and each limiting hole 33 contains a limiting steel ball 37. Below the second pedal 24... A sliding rod 23 is rotatably mounted on a movable cylinder 27. When the door panel 1 needs to be unlocked, the operator steps on a pedal 24. The pedal 24 causes the sliding rod 23 to slide on the movable cylinder 27, and the locking block 29 at the end of the sliding rod 23 also slides inside the movable cylinder 27. A movable rod 30 is fixed below the locking block 29. An annular groove 34 at the end of the movable rod 30 provides a certain amount of space for its sliding within the mounting cylinder 32. The movable rod 30 is slidably mounted inside the mounting cylinder 32, and a second spring 31 is sleeved on the movable rod 30. The second spring 31 is located between the locking block 29 and the mounting cylinder 32. During the sliding of the locking block 29, it will compress or stretch the second spring 31. An installation cylinder 32 is slidably disposed inside the moving cylinder 27. Several limiting holes 33 inside the moving cylinder 27 contain limiting steel balls 37. When the door panel 1 is locked, the limiting steel balls 37 are in a specific position, cooperating with the locking block 29 and other related structures to restrict the movement of the moving cylinder 27, thereby ensuring the locked state of the door panel 1. When the second pedal 24 is pressed, the locking block 29 moves, causing the moving rod 30 to slide within the installation cylinder 32, compressing the second spring 31. As the locking block 29 moves, the position of the limiting steel balls 37 within the limiting holes 33 changes. When the locking block 29 moves to a certain position, the limiting steel balls 37 no longer restrict the moving cylinder 27, allowing it to move freely, thus unlocking the door panel 1. When locking the door panel 1 again, releasing the second pedal 24 causes the spring force of the second spring 31 and the first spring 28 to return all components to the locked position, and the limiting steel ball 37 resumes its limiting function. The design of the second pedal 24 allows operators to start the unlocking process with a simple stepping action, without the need for additional tools, improving the convenience of operation, especially suitable for scenarios where the door panel 1 needs to be opened and closed frequently, such as during maintenance. The cooperation of the limiting steel ball 37 with the limiting hole 33 and the locking block 29 enables precise control of the movement of the moving cylinder 27, thereby accurately realizing the locking and unlocking functions of the door panel 1. When locked, it can ensure that the door panel 1 is fixed at any angle, preventing the cabinet door from closing automatically during maintenance and effectively eliminating safety hazards.

[0025] Working principle: When the lifting motor 11 starts, its output shaft drives the lead screw 15 in the limiting groove 16 inside the first column 12 to rotate. Since the fixing block on the sliding block 17 is threadedly connected to the lead screw 15 and slidably disposed in the limiting groove 16, the rotation of the lead screw 15 will cause the fixing block to drive the sliding block 17 to slide along the first column 12. At the same time, the sliding block 17 and the sliding block 36 on the second column 21 are connected by the connecting plate 18, thereby driving the baffle 19 to rise and fall. A fixing block 20 is provided above the baffle 19, and the rotation between them... A support plate 8 is installed on the rotating rod 35. When the pedal 7 is needed, it is detachably installed on the support plate 8. The operator can stand on the pedal 7 to operate or maintain the equipment inside the box 4. The pedal 7 is made of insulating material to ensure the safety of the operator. An inlet fan is located below the lower plate 13 inside the box 4, and an outlet fan is located above the upper plate 14. The side of the base 10 has an air inlet with a filter box. When the inlet fan is working, it draws in outside air from the air inlet, filters it through the filter box, and then enters the box 4, carrying away the heat generated by the equipment. The hot air is discharged from the top of the box 4 under the action of the outlet fan, forming a forced air circulation to achieve heat dissipation. The sealing frame 6 is fixed to the box 4 and has a sealing gasket inside. The door panel 1 is hinged in the sealing frame 6 and forms a seal when closed by tightly contacting the sealing gasket. The fixed cylinder 22 is fixed to the door panel 1 by two fixed blocks 25. The sliding rod 38 slides in the fixed cylinder 22. One end is connected to the rubber pad 26, and the other end is connected to the moving cylinder 27. The first spring 28 is sleeved on the sliding rod 38. When the door panel 1 is closed, the rubber pad 26 contacts the contact surface, the sliding rod 38 slides and compresses the first spring 28, and the limiting tooth 3 restricts the movement of the sliding rod 38. When unlocking, stepping on the pedal 24 causes the sliding rod 23 to slide on the moving cylinder 27, and the locking block 29 moves accordingly, compressing the second spring 31, causing the limiting steel ball 37 to change position within the limiting hole 33, releasing the restriction on the moving cylinder 27, and unlocking the door panel 1. When the pedal 24 is released, all components reset and lock under the action of the spring force. The lifting assembly design allows for flexible adjustment of the internal operating space of the enclosure 4 according to actual needs, facilitating operation and maintenance of equipment in different positions, improving space utilization and operational convenience. The detachable foot pedal 7 further optimizes the operating space, meeting operational needs in various scenarios, and the insulating material ensures operational safety. The intake and exhaust fans work together to create forced air circulation, quickly and effectively dissipating heat from inside the enclosure 4, ensuring the equipment operates in a suitable temperature environment and extending its lifespan. The filter box at the air inlet filters the air entering the enclosure 4, preventing dust, debris, and other contaminants from entering and damaging the equipment. The sealing frame 6 and sealing gasket in the sealing assembly effectively prevent external dust and moisture from entering the cabinet 4, protecting the internal equipment from the influence of the external environment and providing a good operating environment for the equipment. The locking assembly achieves precise locking and unlocking of the door panel 1 through the cooperation of multiple structures. The limit teeth 3 and limit steel balls 37 and other structures ensure the stability of the door panel 1 in the locked state, which can be fixed at any angle to prevent the cabinet door from closing automatically during maintenance, effectively eliminating safety hazards. The unlocking method of the second pedal 24 is convenient and quick, without the need for additional tools, and is especially suitable for maintenance scenarios where the door panel 1 is frequently opened and closed, improving operating efficiency and safety.
