Description

Technical Field

[0001] This utility model relates to the field of electrical box technology, specifically to an electrical box that allows for easy installation of circuit boards without drilling. Background Technology

[0002] Traditional electrical boxes typically use metal casings, requiring on-site drilling for circuit board installation—a cumbersome and inefficient process. More importantly, once the mounting holes in existing electrical boxes are drilled, their positions and dimensions are fixed. When different circuit boards are needed later, new holes must be drilled, increasing installation difficulty and time costs, and causing significant damage to the electrical box itself, affecting its overall structural strength and lifespan.

[0003] Therefore, developing an electrical box that can easily install circuit boards of different specifications without requiring destructive operation on the box itself is of great practical significance, and this application was developed in this context. Utility Model Content

[0005] This utility model provides the following technical solution: an electrical box for easy installation of circuit boards without drilling, comprising a plastic box body, an upper cover mounted on the upper part of the plastic box body via a hinge, one side of the upper cover being detachably connected to the plastic box body via a latch, a circuit board being provided inside the plastic box body, and an integrally formed suspended column on the bottom plate inside the plastic box body, the suspended column being provided with mounting holes for installing circuit boards.

[0006] Preferably, the plastic box body is fixed with four mounting ears at its four corners.

[0007] Preferably, the inner surface of the top cover is provided with a sealing ring.

[0008] Preferably, a connecting piece is provided between the circuit board and the overhead column, one end of the connecting piece is detachably fixed to the overhead column, and the other end of the connecting piece is detachably fixed to the circuit board.

[0009] Preferably, one end of the connecting piece is provided with a through hole, and the end of the connecting piece with the through hole is fixed to the mounting hole by a first bolt;

[0010] The circuit board has a through hole, and the other end of the connecting piece with the through hole is fixed to the connecting hole of the circuit board by a second bolt.

[0011] Preferably, the connecting piece has a strip-shaped adjustment groove, the second bolt is movably disposed in the strip-shaped adjustment groove, and the head of the second bolt passes through the connecting hole and is threadedly connected to a fixing nut.

[0012] Preferably, the number of the overhead columns is four, and the four overhead columns are set at the four corners of the bottom plate of the plastic box.

[0013] Compared with the prior art, the beneficial effects of this utility model are as follows: This utility model provides an electrical box that requires no drilling and can easily install circuit boards of different specifications. By using a plastic box body and an integrally formed overhead column with mounting holes in its internal bottom plate, on-site drilling is avoided.

[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. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0022] Please see Figure 1-6 .

[0023] Example 1

[0024] An electrical box for easy circuit board installation without drilling includes a plastic box body 1. A top cover 3 is mounted on the upper part of the plastic box body 1 via a hinge 2. One side of the top cover 3 is detachably connected to the plastic box body 1 via a latch 4. A circuit board 5 is installed inside the plastic box body 1, and an overhead column 6 is integrally formed on the bottom plate inside the plastic box body 1. The overhead column 6 has mounting holes 7 for installing the circuit board 5. By pre-setting the overhead column 6 on the bottom plate of the plastic box body 1, the circuit board 5 can be quickly installed on it. Compared with traditional metal shells, drilling is not required during installation, making it convenient to use.

[0025] The plastic box 1 has four mounting ears 8 fixed at its four corners.

[0026] The inner surface of the top cover 3 is provided with a sealing ring 9 to ensure the sealing effect inside the plastic box 1. When applied in environments such as a breeding farm, it can effectively prevent damage to the internal circuit components.

[0027] Example 2

[0028] Example 2 has a structure that is largely the same as Example 1, except that:

[0029] Please refer to the main text. Figure 4 and Figure 5 A connecting piece 10 is provided between the circuit board 5 and the overhead column 6. The connecting piece 10 can be a metal sheet structure. One end of the connecting piece 10 is detachably fixed to the overhead column 6, and the other end of the connecting piece 10 is detachably fixed to the circuit board 5.

[0030] By using the connecting piece 10, one end of the connecting piece 10 can be directly fixed to the overhead column 6, and then the circuit board 5 can be fixed to the other end of the connecting piece 10, thus realizing the installation of the circuit board 5 and acting as an intermediate medium. The effect is that when disassembling the circuit board 5 later, only the circuit board 5 and the connecting piece 10 need to be removed, without needing to remove the connecting piece 10 and the overhead column 6, thereby effectively preventing damage to the overhead column 6 during the installation and disassembly of the circuit board 5.

[0031] Specifically, one end of the connecting piece 10 has a through hole 11, and the end of the connecting piece 10 with the through hole 11 is fixed to the mounting hole 7 by a first bolt 12. The circuit board 5 has a through hole, and the other end of the connecting piece 10 with the through hole 11 is fixed to the connecting hole of the circuit board 5 by a second bolt 13.

[0032] Furthermore, the connecting piece 10 has a strip-shaped adjustment groove 14, the second bolt 13 is movably disposed in the strip-shaped adjustment groove 14, and the head of the second bolt 13 passes through the connecting hole and is threadedly connected to a fixing nut 15.

[0033] With the above structure, the second bolt 13 can be moved and adjusted within the strip adjustment groove 14, and one end of the connecting piece 10 can be rotated on the overhead column 6 to further adjust the position of the second bolt 13. This makes it convenient to fix circuit boards 5 of various specifications.

[0034] In this embodiment, there are four overhead columns 6. The four overhead columns 6 are set at the four corners of the bottom plate of the plastic box 1. Each pair of adjacent connecting pieces 10 and the side of the plastic box 1 form a triangular structure, thereby preventing the circuit board 5 from shaking after installation.

[0035] Example 3

[0036] Example 3 is based on Example 1 or Example 2; please refer to the relevant documentation. Figure 6 An air-cooling mechanism is installed inside the plastic casing 1. This mechanism includes copper pipes 16, with both ends of the copper pipes 16 fixed to both ends of the plastic casing 1. The copper pipes 16 are arranged on the bottom plate of the plastic casing 1. An exhaust fan 17 is fixed to one side of the plastic casing 1, and the exhaust port of the exhaust fan 17 is fixed to one end of the copper pipes 16. It can be understood that since both ends of the copper pipes 16 penetrate both sides of the plastic casing 1, the interior of the copper pipes 16 is completely isolated from the interior of the plastic casing 1, and will not affect the sealing effect inside the plastic casing 1. Additionally, please refer to... Figure 4 Due to the installation of the overhead column 6, the circuit board 5 is suspended, and the copper pipe 16 is installed in the space between the circuit board 5 and the plastic box 1. When the electrical components on the circuit board 5 are working, they generate heat, which is transferred to the copper pipe 16. The heat is then quickly carried away by the airflow inside the copper pipe 16, thus ensuring the heat dissipation performance of the plastic box 1.

[0037] In summary, this utility model aims to provide an electrical box that eliminates the need for drilling and facilitates the installation of circuit boards 5 of different specifications. By using a plastic box body 1 and an integrally formed overhead column 6 with mounting holes 7 on its internal bottom plate, on-site drilling is avoided. At the same time, the design of detachable connecting pieces 10 and strip-shaped adjustment grooves 14 flexibly adapts to the installation requirements of various specifications of circuit boards 5, effectively reducing installation difficulty and time costs, and avoiding destructive operations on the electrical box body, thus ensuring the overall structural strength and service life of the electrical box. In addition, in embodiment three, a wind-cooling mechanism is also provided inside the plastic box body 1 to ensure the heat dissipation performance of the electrical box under sealed conditions.
