Technical Field

[0001] This utility model relates to the field of junction box technology, specifically to a junction box that can be quickly disassembled and assembled. Background Technology

[0002] A junction box is a device used to connect electrical circuits and is a key component of circuit connections. Essentially, it is a box with wiring holes designed to connect wires, switch on / off circuits, and distribute power. It is widely used in many fields such as power, communications, shipbuilding, construction, and machinery, and is an important element to ensure stable wire connections and smooth circuit operation.

[0003] Chinese patent CN220325224U discloses a junction box, including a box body and a mounting base disposed below the box body, and a mounting shaft fixed on the box body. One end of the mounting shaft is rotatably connected to the mounting base, and the mounting base is provided with a steering limit component for turning the box body and limiting its movement after turning.

[0004] The aforementioned junction box, through the cooperation of the steering limit component, the pushing component, and the buffer component, allows the operator to adjust and maintain the wiring at different angles of the box from the same position. This facilitates more flexible adjustment and maintenance of the box after installation, while preventing direct impact damage and ensuring more stable use. However, disassembling and reassembling the box is relatively troublesome when inspecting and maintaining the internal wiring, causing inconvenience to the inspection and maintenance work. Therefore, we propose a junction box that can be quickly disassembled and assembled. Utility Model Content

[0005] The purpose of this invention is to provide a junction box that can be quickly assembled and disassembled, so as to solve the problems mentioned in the background art.

[0006] To achieve the above objectives, this utility model provides the following technical solution: a quick-assembly and disassembly junction box, comprising a junction box body, a cover, connectors, terminals, and locking rods. The connectors are all installed inside the outer wall of the junction box body, and the terminals are installed inside the junction box body. The cover is located at the top of the junction box body, and a drive cavity is provided inside the cover. A gear is installed inside the drive cavity. The locking rods are all located inside the drive cavities on both sides of the gear, and one side of each locking rod surface has equally spaced toothed grooves that mesh tightly with the gear. One end of the locking rod passes through an opening slot on the outer wall of the cover and extends into a locking groove on the inner wall of the junction box body. A dovetail slider is fixed on the outer wall of the locking rod on the side away from the gear, and the dovetail slider is slidably connected to a dovetail groove on the inner wall of the drive cavity.

[0007] Preferably, an airbag ring is adhered to the inner wall of the connector.

[0008] Preferably, an inflatable ball is adhered to the inner wall of the junction box body on one side of the connector, and one end of the inflatable ball is connected to an air supply pipe, and the air supply pipe is connected to the airbag ring.

[0009] Preferably, the bottom of the inflatable ball is connected to an air inlet pipe, and a one-way valve is installed inside the air inlet pipe.

[0010] Preferably, a rotating rod is fixed at the center of the top of the gear, and the top of the rotating rod extends into the disassembly groove of the top of the cover and is provided with a groove.

[0011] Preferably, a sealing plug is installed on the top of the box cover above the disassembly slot via a rotating shaft, and a sealing cover plate is glued to the bottom of the sealing plug. The sealing cover plate is tightly engaged with the disassembly slot and tightly fitted with the rotating rod.

[0012] Preferably, mounting holes are provided at the corner positions inside the junction box body.

[0013] Compared with the prior art, the beneficial effects of this utility model are:

[0014] During reinstallation, place the cover on the junction box body, insert the tool into the groove at the top of the rotating rod, and rotate the rotating rod to make the gear rotate. The gear drives the locking rod to move horizontally through the tooth groove. The locking rod drives the dovetail slider to slide along the dovetail groove.

[0021] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments of the present utility model. All other embodiments obtained by those skilled in the art based on the embodiments of the present utility model without creative effort are within the scope of protection of the present utility model.

[0022] Please see Figure 1-4 The present invention provides an embodiment of a quick-disassembly junction box, comprising a junction box body 1, a box cover 2, a connector 3, a terminal block 9, and a locking rod 13. The connector 3 is installed inside the outer wall of the junction box body 1, and the terminal block 9 is installed inside the junction box body 1.

[0023] The cover 2 is located at the top of the junction box body 1. The inside of the cover 2 is provided with a drive cavity 11, and a gear 12 is installed inside the drive cavity 11. The locking rods 13 are all located inside the drive cavities 11 on both sides of the gear 12. One side of the surface of the locking rod 13 is provided with equally spaced tooth grooves 17. The tooth grooves 17 are tightly meshed with the gear 12. One end of the locking rod 13 passes through the opening groove 14 on the outer wall of the cover 2 and extends into the locking groove 10 on the inner wall of the junction box body 1. A dovetail slider 16 is fixed on the outer wall of the locking rod 13 away from the gear 12. The dovetail slider 16 is slidably connected to the dovetail groove 15 on the inner wall of the drive cavity 11.

[0024] Specifically, cover the junction box 2 onto the junction box body 1, insert the tool into the groove 19 at the top of the rotating rod 18, rotate the rotating rod 18 to make the gear 12 rotate, the gear 12 drives the locking rod 13 to move through the tooth groove 17, the locking rod 13 drives the dovetail slider 16 to slide along the dovetail groove 15, one end of the locking rod 13 extends out from the opening groove 14 and inserts into the locking groove 10 on the inner wall of the junction box body 1, and fixes the cover 2 and the junction box body 1, thus completing the installation of the cover 2;

[0025] When it is necessary to inspect and maintain the internal wiring of the junction box body 1, open the sealing plug 21, use a tool to rotate the rotating rod 18 in the opposite direction to make the gear 12 rotate and drive the locking rod 13 to move horizontally. One end of the locking rod 13 disengages from the locking groove 10 and retracts into the opening groove 14, so that the box cover 2 is separated from the junction box body 1. Then lift the box cover 2 to open the junction box body 1, so that the junction box can be quickly disassembled and installed, and is easy to inspect and maintain.

[0026] An airbag ring 301 is attached to the inner wall of connector 3;

[0027] An inflatable ball 5 is attached to the inner wall of the junction box body 1 on one side of the connector 3, and one end of the inflatable ball 5 is connected to an air supply pipe 4, and the air supply pipe 4 is connected to the airbag ring 301.

[0028] The bottom of the inflatable ball 5 is connected to an air inlet pipe 7, and a one-way valve 6 is installed inside the air inlet pipe 7;

[0029] Specifically, the wire harness is passed through the connector 3 into the junction box body 1 and connected through the terminal 9. Pressing the inflation ball 5 allows air to enter the inflation ball 5 through the air inlet pipe 7 and enter the air bag ring 301 through the air outlet pipe 4. After the air bag ring 301 is inflated, it expands and tightly wraps the wire harness, which plays a limiting role in the wire harness and prevents it from shaking and rubbing, thus preventing damage. It can also seal the wire harness and the connector 3, thus achieving the effect of dustproof and waterproof.

[0030] A rotating rod 18 is fixed at the center of the top of the gear 12, and the top of the rotating rod 18 extends into the disassembly groove 20 at the top of the cover 2 and is provided with a groove 19.

[0031] A sealing plug 21 is installed on the top of the box cover 2 above the disassembly slot 20 via a rotating shaft 23, and a sealing cover plate 22 is glued to the bottom of the sealing plug 21. The sealing cover plate 22 is tightly engaged with the disassembly slot 20, and the sealing cover plate 22 is tightly fitted with the rotating rod 18.

[0032] Specifically, flipping the sealing plug 21 to make it rotate around the rotating shaft 23 and inserting the sealing cover plate 22 into the disassembly groove 20 can seal the disassembly groove 20 and block the rotating rod 18.

[0033] Mounting holes 8 are provided at the corners inside the junction box body 1.

[0034] In this embodiment, the wiring harness is first threaded through the connector 3 into the junction box body 1 and connected via the terminal 9. Pressing the inflatable balloon 5 allows air to enter through the air inlet pipe 7 and then through the air outlet pipe 4 into the airbag ring 301. The airbag ring 301 inflates and expands, tightly encasing the wiring harness, thus limiting its movement and preventing damage from shaking and friction. It also seals the wiring harness against the connector 3, providing dust and water protection. Next, the cover 2 is placed on the junction box body 1, and a tool is inserted into the groove 19 at the top of the rotating rod 18. Rotating the rotating rod 18 causes the gear 12 to rotate. The gear 12 drives the locking rod 13 to move horizontally through the tooth groove 17. The locking rod 13 then moves the dovetail slider 16 along the dovetail groove 15. One end of the locking rod 13 extends from the opening slot 14 and inserts into the locking groove 10 on the inner wall of the junction box body 1 to fix the cover 2 and the junction box body 1, thus completing the installation of the cover 2. Then, the sealing plug 21 is flipped over to rotate around the rotating shaft 23, and the sealing cover plate 22 is inserted into the disassembly groove 20 to seal the disassembly groove 20 and cover the rotating rod 18. When it is necessary to inspect and maintain the internal wiring of the junction box body 1, the sealing plug 21 is opened, and the rotating rod 18 is rotated in the opposite direction to make the gear 12 rotate and drive the locking rod 13 to move horizontally. One end of the locking rod 13 is dislodged from the locking groove 10 and retracted into the opening slot 14, so that the cover 2 is separated from the junction box body 1. Then, the cover 2 is lifted to open the junction box body 1, thus making the junction box easy to disassemble and assemble quickly, and easy to inspect and maintain.

[0035] Obviously, the embodiments described above are only some embodiments of this utility model, and not all embodiments. Based on the embodiments of this utility model, all other embodiments obtained by those skilled in the art without creative effort should fall within the protection scope of this utility model.
