Description

Technical Field

[0001] The utility model relates to the technical field of cable junction boxes, in particular to a prefabricated cable junction box. Background Art

[0002] The cable junction box is a power system device, and its main functions include: cable branching and cable transfer. When the cable line is long, the traditional method is to make a cable intermediate head to connect multiple cable sections to meet the power supply length requirements, but the cable intermediate head has safety hazards and cannot meet the requirements of long-term use of the cable. The cable junction box contains components such as isolating switches to ensure high reliability and safety during its operation.

[0003] Most of the existing cable junction boxes are located in outdoor green belts. In order to ensure better heat dissipation of the equipment inside the junction box, heat dissipation holes are usually opened. This causes rainwater to enter the box through the heat dissipation holes when it rains, which can easily damage the electronic components inside the box, resulting in poor waterproof effect. Utility Model Content

[0004] The utility model aims to provide a prefabricated cable junction box to solve the problem that the currently used cable junction box is not well waterproof as mentioned in the above background technology.

[0005] To achieve the above objectives, the utility model provides the following technical solutions: a prefabricated cable junction box, comprising: a base and a door lock, a box body is installed on the top of the base, a box door is connected to one side of the box body through a hinge, and the door lock is installed on one side of the box door.

[0006] Preferably, a pressing block is installed on one side of the box door, and a sealing ring is provided between the pressing block and the groove of the box body.

[0007] Preferably, a driving motor is installed on the inner wall of the box body, an output end of the driving motor is connected to a screw rod, and a screw sleeve is sleeved on the outer side of the screw rod.

[0008] Preferably, both sides of the screw sleeve are connected to baffles via fixing rods, and the side of the baffle away from the screw sleeve is connected to a track via a slider.

[0009] Preferably, a fixing frame is installed inside the box body, a wire clamping frame is installed on one side of the fixing frame, and movable blocks are connected to both sides of the wire clamping frame via rotating shafts.

[0010] Preferably, one side of the movable block is connected to a connecting rod via a rotating shaft, and the side of the connecting rod away from the movable block is connected to a connecting rod via a rotating shaft.

[0011] Preferably, a sliding block is installed between the connecting rod and the slide groove of the fixed frame, a telescopic rod is installed on one side of the sliding block, a movable spring is installed between the telescopic rod and the groove of the fixed frame, and rubber pads are installed on the inner walls of the wire clamping frame and the movable block.

[0012] Compared with the prior art, the beneficial effect of the utility model is that when the prefabricated cable junction box is in use, the driving motor can be started according to demand, and the driving motor makes the baffle move upward through the cooperation of the screw and the screw sleeve, and the baffle will slide along the track through the sliding block while moving, thereby ensuring the stability of the entire baffle during movement. After the baffle moves to the heat dissipation hole position on one side of the box body, rainwater can be prevented from entering the interior of the box body through the heat dissipation hole. At the same time, the pressure block on one side of the box door squeezes the sealing ring, which can make the waterproof effect of the entire box body better, and prevent rainwater from entering the interior of the junction box and causing damage to the internal equipment. This is the use feature of the prefabricated cable junction box.

[0013] 1. When the prefabricated cable junction box is in use, in order to prevent rainwater from entering the interior of the junction box, the screw can be driven to rotate by a driving motor, and the baffle can be moved with the cooperation of the screw sleeve. At this time, the baffle can block the position of the heat dissipation hole, thereby making the sealing effect of the entire junction box better, preventing rainwater from entering the interior of the box, and increasing the waterproof effect of the entire box.

[0014] 2. When using the prefabricated cable junction box, in order to avoid damage to the cables caused by long-term friction between the cables and the inner wall of the junction box, the cables can be moved to the inside of the wire clamping rack and the cables can be limited by the movable block. At this time, the rubber pads on the inner wall of the wire clamping rack and the movable block can protect the cables and avoid friction between the cables and the inner wall of the junction box.

DETAILED DESCRIPTION

[0023] The following will be combined with the drawings in the embodiments of the utility model to clearly and completely describe the technical solutions in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments in the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.

[0024] See also Figure 1 , Figure 2 and Figure 3 The utility model provides a technical solution: a prefabricated cable junction box, comprising: a base 1 and a door lock 4, a box body 2 is installed on the top of the base 1, a box door 3 is connected to one side of the box body 2 through a hinge, and the door lock 4 is installed on one side of the box door 3.

[0025] A pressure block 5 is installed on one side of the box door 3, and a sealing ring 6 is arranged between the pressure block 5 and the groove of the box body 2. A driving motor 7 is installed on the inner wall of the box body 2. The output end of the driving motor 7 is connected to a screw rod 8, and a threaded sleeve 9 is sleeved on the outer side of the screw rod 8. Both sides of the threaded sleeve 9 are connected to baffles 10 through fixed rods. The side of the baffle 10 away from the threaded sleeve 9 is connected to a track 11 through a slider, and the baffle 10 forms a sliding structure with the track 11 through the slider.

[0026] During specific implementation, when it is necessary to increase the rainproof effect of the entire cable junction box, the internal drive motor 7 can be started, and the drive motor 7 will drive the top screw 8 to rotate. The top of the screw 8 is connected to the inside of the box body 2 through a bearing, and a screw sleeve 9 is sleeved on the outside of the screw 8, and the two sides of the screw sleeve 9 are connected to the baffle 10 through a fixing rod. At this time, the rotation of the screw 8 will drive the screw sleeve 9 to move, and with the cooperation of the fixing rod, the baffle 10 moves upward. While moving, the baffle 10 will slide along the track 11 through a slider on one side, thereby ensuring the stability of the movement of the entire baffle 10. At this time, the baffle 10 can be moved to one side of the heat dissipation hole on one side of the box body 2. The baffle 10 can prevent rainwater from entering the inside of the junction box through the heat dissipation hole, thereby making the rainproof effect of the entire junction box better. At the same time, when the box door 3 is locked by the door lock 4, the pressure block 5 on one side of the box door 3 squeezes the sealing gasket in the groove of the box body 2, so that the sealing of the entire junction box is better.

[0027] On the contrary, when normal heat dissipation is needed, the drive motor 7 can be started to drive the screw 8 to rotate in the opposite direction, and with the cooperation of the screw sleeve 9, the baffle 10 can move in the opposite direction. The baffle 10 will not block the heat dissipation hole. At this time, the junction box can dissipate heat normally without affecting the normal heat dissipation effect of the junction box.

[0028] See also Figure 2 , Figure 3 , Figure 5 and Figure 6 It can be seen that when in use, the baffle 10 can be moved to one side of the heat dissipation hole according to the use requirements, so as to prevent rainwater from entering the inside of the junction box, so that the rainproof effect of the entire junction box is better.

[0029] A fixed frame 12 is installed inside the box body 2, and a wire clamping frame 13 is installed on one side of the fixed frame 12. Both sides of the wire clamping frame 13 are connected with movable blocks 14 through a rotating shaft. One side of the movable block 14 is connected with a connecting rod 15 through a rotating shaft. The side of the connecting rod 15 away from the movable block 14 is connected with a connecting rod 16 through a rotating shaft. A sliding block 17 is installed between the connecting rod 16 and the slide groove of the fixed frame 12, and a telescopic rod 18 is installed on one side of the sliding block 17. A movable spring 19 is installed between the telescopic rod 18 and the groove of the fixed frame 12. Rubber pads 20 are installed on the inner walls of the wire clamping frame 13 and the movable block 14. The movable block 14 forms a rotating structure with the wire clamping frame 13 through the rotating shaft.

[0030] In a specific implementation, when the prefabricated cable junction box needs to connect cables, the movable block 14 can be pushed to both sides, so that the movable block 14 rotates through the rotating shaft between the cable clamping frame 13, and the movable block 14 pushes the connecting rod 15 to move through the rotating shaft while rotating. Since the other side of the connecting rod 15 is connected to the bottom of the connecting rod 16 through the rotating shaft, it is squeezed by the connecting rod 15, which pushes the connecting rod 16 to move, so that the connecting rod 16 slides along the sliding groove of the fixed frame 12 through the sliding block 17. The sliding block 17 pulls the telescopic rod 18 to move while sliding, so that the telescopic rod 18 pulls the movable block 14 in the groove of the fixed frame 12. The movable spring 19 is extended and the movable spring 19 is in a stretched state. Then the cable can be moved to the inside of the wire clamping frame 13, and then the movable block 14 is released. At this time, the telescopic rod 18 is reset by the movable spring 19, and the connecting rod 16 and the connecting rod 15 are pulled to move by the sliding block 17, so that the two groups of movable blocks 14 rotate close to each other. At this time, the cable can be limited in the wire clamping frame 13, and rubber pads 20 are installed on the inner walls of the wire clamping frame 13 and the movable block 14. The rubber pads 20 can protect the cable to avoid direct friction contact between the cable and the inner wall of the junction box, which causes cable wear.

[0031] See also Figure 4 and Figure 7 It can be known that when in use, the cable can be moved into the groove of the cable clamping frame 13 , and the cable can be protected by the movable block 14 and the rubber pad 20 on the inner wall of the cable clamping frame 13 .

[0032] To sum up: when the prefabricated cable junction box is in use, the entire junction box can be installed in the green belt using a prefabricated foundation, and the foundation of the prefabricated cable junction box is made of reinforced concrete, which is waterproof, moisture-proof and durable, and greatly shortens the construction period for projects with tight construction period requirements. Then, the cables are connected to the junction box through the wiring holes at the bottom of the base 1 and connected to the disconnector and other components in the junction box. At this time, the junction box can work normally, greatly ensuring the safety and durability of the power line. This is the use feature of the prefabricated cable junction box.
