[0002] Existing network junction boxes include a housing, a circuit board inside the housing, and modules mounted on the circuit board. The housing consists of a base and a top cover that are detachably connected. The detachable connection between the top cover and the base typically employs the following structure: a through-hole is formed in the top cover, and a mounting post with an internal threaded hole corresponding to the through-hole is provided in the base. A screw passes through the through-hole and is threaded into the internal threaded hole of the mounting post. Furthermore, a cable pass-through hole is formed on the side wall of the housing, through which the network cable passes to connect to the module during use.

[0003] Existing prefabricated junction box designs are mostly single, integral structures. When multiple sets of wires need to be run and installed, these junction boxes are not convenient for interconnection, easily leading to unstable connections between pairs and failing to form a unified whole after installation in the designated location. This scattered layout not only affects the overall aesthetics of the installation site but also brings inconvenience to subsequent maintenance and management. Therefore, a prefabricated junction box is needed to help solve this problem. Utility Model Content

[0004] Therefore, the purpose of this utility model is to provide a prefabricated junction box to solve the problem that existing prefabricated junction box designs are mostly single, integral structures. When multiple sets of wires need to be run and installed, these junction boxes are not convenient to connect to each other, which can easily lead to unstable connections between pairs and make it difficult to form a unified whole after installation in the designated position. This scattered layout not only affects the overall aesthetics of the installation site, but also brings inconvenient technical problems for subsequent maintenance and management.

[0005] To achieve the above objectives, this utility model provides the following technical solution: an assembled junction box, comprising a junction box body and a top cover, wherein the junction box body has an internal receiving box for accommodating components, and each of the four corners of the receiving box has a protruding seat with a first fixing hole. The four corners of the top cover have a second fixing hole, and fixing bolts are installed at the first fixing hole and the second fixing hole. Both sides of the junction box body have through holes, and a wire threading assembly is provided on the outer side of the junction box body corresponding to the through hole.

[0006] A plug-in slot is provided on one side of the junction box body adjacent to the wiring assembly. A positioning hole is provided on the inner side of the plug-in slot. A plug-in block is provided on one side of the junction box body away from the plug-in slot. The plug-in slot and the plug-in block are connected to each other. A positioning cavity is provided inside the plug-in block. A positioning component is installed in the positioning cavity. The positioning hole and the positioning component are connected to each other for positioning.

[0007] Furthermore, the positioning component includes a positioning pin slidably disposed within the positioning cavity, the positioning pin being engaged with the positioning hole, an ejection spring for assisting the positioning pin to push is installed within the positioning cavity, a pull ring is disposed below the insertion block, a connecting strap is fixed to the top of the pull ring, and the end of the connecting strap away from the pull ring is fixed to the end of the positioning pin facing the ejection spring.

[0008] Furthermore, a rotating wheel is rotatably provided inside the plug block, and the connecting belt is wrapped around and installed on the outer side of the rotating wheel.

[0009] Furthermore, the threading assembly includes a threading tube fixed at the through hole, a threading bolt threaded onto the threading tube, and a threading hole for threading wires to pass through the threading bolt.

[0010] Furthermore, a waterproof air cushion is embedded inside the threading tube, and the waterproof air cushion is in the shape of a ring.

[0011] Furthermore, a sealing cavity is provided at the top of the junction box body, and a sealing component for auxiliary sealing is installed in the sealing cavity.

[0012] Furthermore, the sealing assembly includes a sealing gasket slidably embedded in the sealing cavity, and an ejector spring for assisting the sealing gasket in pushing is installed in the sealing cavity.

[0013] In summary, the present invention has the following advantages: By using the plug slots and positioning holes on the side of the junction box body, as well as the cooperation between the plug block and the positioning component, when multiple junction boxes need to be installed, pulling the pull ring will pull the connecting strip, which in turn pulls the positioning pin. During the pulling of the positioning pin, the push-out spring is compressed. At this time, the plug block is inserted into the plug slot, and the pull ring is released. Under the action of the compressed push-out spring, the positioning pin is pushed, thereby achieving overall stability between the two junction box bodies and forming a whole. This facilitates subsequent maintenance and management and ensures the overall aesthetics of the installation site.

[0014] The sealing components allow the top cover to be placed over the top of the junction box during operation and secured with bolts. As the junction box and the top cover press against each other, the sealing gasket is compressed, and the ejector spring is compressed and retracted, thus achieving a complete seal at the connection between the junction box and the top cover. This ensures that no liquid will enter through the gaps at the connection between the junction box and the top cover during subsequent operation, improving the overall sealing performance of the junction box.

[0020] The technical solutions of the present invention will be clearly and completely described below with reference to the accompanying drawings. The embodiments described below with reference to the accompanying drawings are exemplary and are only used to explain the present invention, and should not be construed as limiting the present invention.

[0021] A type of assembled junction box, such as Figure 1-4 As shown, the device includes a junction box body 1 and a top cover 5. The junction box body 1 has an internal receiving box 2 for accommodating components. Each of the four corners of the receiving box 2 has a protruding seat 3 with a first fixing hole 4. The four corners of the top cover 5 have second fixing holes 6. Fixing bolts 7 are installed at the first fixing holes 4 and the second fixing holes 6. A sealing cavity is provided at the top of the junction box body 1. A sealing component 13 for auxiliary sealing is installed in the sealing cavity. The sealing component 13 includes a sealing gasket 14 that is slidably embedded in the sealing cavity. An ejector spring 15 that pushes the auxiliary sealing gasket 14 is installed in the sealing cavity.

[0022] With the sealing component 13, the top cover 5 can be placed over the top of the junction box body 1 during operation and secured with the fixing bolts 7. When the junction box body 1 and the top cover 5 press against each other, the sealing gasket 14 is compressed and the ejector spring 15 is compressed and retracted, thereby achieving overall sealing treatment at the connection between the junction box body 1 and the top cover 5. This ensures that no liquid will enter through the connection gap during subsequent operation, improving the overall sealing performance of the junction box.

[0023] Both sides of the junction box body 1 are provided with through holes. A wire threading assembly 8 is provided on the outer side of the junction box body 1 corresponding to the through hole. The wire threading assembly 8 includes a wire threading tube 9 fixed at the through hole. A wire clamping bolt 10 is threaded on the wire threading tube 9. A wire threading hole 101 for the wire 12 to pass through is provided at the wire clamping bolt 10. A waterproof air cushion 11 is embedded inside the wire threading tube 9. The waterproof air cushion 11 is annular. With the waterproof air cushion 11, when the wire clamping bolt 10 is squeezed during operation, the waterproof air cushion 11 can be pressed around the wire 12, thereby achieving the overall sealing of the wire threading assembly 8 and minimizing the possibility of liquid entering the junction box body 1 through the through hole.

[0024] The junction box body 1 has a plug-in groove 16 on one side adjacent to the wiring assembly 8. A positioning hole 17 is provided on the inner side of the plug-in groove 16. A plug-in block 18 is provided on the side of the junction box body 1 away from the plug-in groove 16. The plug-in groove 16 and the plug-in block 18 are connected. A positioning cavity is provided inside the plug-in block 18. A positioning assembly 19 is installed in the positioning cavity. The positioning hole 17 is connected to the positioning assembly 19 for positioning. The positioning assembly 19 includes a positioning pin 20 that is slidably disposed in the positioning cavity. The positioning pin 20 is connected to the positioning hole 17. An ejection spring 21 is installed in the positioning cavity to assist the positioning pin 20 in pushing. A pull ring 24 is provided below the plug-in block 18. A connecting strap 22 is fixed at the top of the pull ring 24. The end of the connecting strap 22 away from the pull ring 24 is fixed to the end of the positioning pin 20 facing the ejection spring 21. A rotating wheel 23 is rotatably disposed inside the plug-in block 18. The connecting strap 22 is wound around the outer side of the rotating wheel 23.

[0025] By utilizing the interlocking slots 16 and positioning holes 17, as well as the interlocking blocks 18 and positioning components 19 on the side of the junction box body 1, when multiple junction boxes need to be installed, pulling the pull ring 24 will cause the connecting belt 22 to be pulled, which in turn will cause the positioning pin 20 to be pulled. During the pulling of the positioning pin 20, the push-out spring 21 will be compressed. At this time, the interlocking block 18 is inserted into the interlocking slot 16, and the pull ring 24 is released. Under the action of the compressed push-out spring 21, the positioning pin 20 is pushed, thereby achieving overall stability between the two junction box bodies 1 and forming a whole, which facilitates subsequent maintenance and management and ensures the overall aesthetics of the installation site.

[0026] The working principle of this utility model:

[0027] When the two junction box bodies 1 need to be connected, pull the pull ring 24. When the pull ring 24 is pulled, the connecting strip 22 is pulled. When the connecting strip 22 is pulled, the positioning pin 20 is pulled. During the process of the positioning pin 20 being pulled, the push-out spring 21 is compressed. At this time, the plug block 18 is inserted into the plug slot 16. Release the pull ring 24. Under the action of the compressed push-out spring 21, the positioning pin 20 is pushed, thereby realizing the overall stable treatment between the two junction box bodies 1 and forming a whole.

[0028] When fixing the wire 12, the wire 12 is threaded through the through hole. The wire clamping bolt 10 is rotated, and the threaded engagement between the wire threading cylinder 9 and the wire clamping bolt 10 causes the wire clamping bolt 10 to move into the wire threading cylinder 9. The wire clamping bolt 10 then compresses the waterproof air cushion 11, which, during compression, presses the waterproof air cushion 11 around the wire 12, thus achieving overall sealing at the wire threading assembly 8.

[0029] During installation, the top cover 5 is placed over the top of the junction box body 1 and secured with fixing bolts 7. When the junction box body 1 and the top cover 5 press against each other, the sealing gasket 14 is compressed and the ejector spring 15 is compressed and retracted, thereby achieving overall sealing treatment at the connection between the junction box body 1 and the top cover 5.
