Description

Technical Field

[0001] This utility model relates to the field of installation technology for strong and weak current boxes, and in particular to a pre-embedded mounting bracket for strong and weak current boxes. Background Technology

[0002] High-voltage and low-voltage distribution boxes are two important types of power distribution equipment, each responsible for different functions of power and signal distribution. High-voltage boxes are primarily used for the distribution and control of 220V / 380V AC power, providing power support for high-power equipment such as lighting, sockets, and air conditioners. Low-voltage boxes, on the other hand, manage low-voltage signal transmission systems such as network communication, cable television, and security monitoring. In traditional buildings, high-voltage and low-voltage boxes are typically designed as separate units, each installed independently in different areas of the building.

[0003] When installing electrical boxes for both high and low voltage, it is necessary to construct grooves of the corresponding size on the completed wall, or to reserve space of the corresponding size during wall construction to accommodate the installation of electrical boxes for both high and low voltage. However, both methods increase the construction process of the wall and make it impossible to precisely control the installation height of electrical boxes for both high and low voltage. Utility Model Content

[0004] To address the shortcomings of existing technologies, this utility model provides a pre-embedded mounting bracket for strong and weak current boxes, which solves the problem of increased wall construction efficiency when installing strong and weak current boxes in existing technologies.

[0023] The technical solution of this utility model will be further described below with reference to the accompanying drawings and embodiments.

[0024] In traditional construction, the slot for the electrical box body 1 is usually formed by post-installation grooving. After the electrical box body 1 is installed into the slot, any excess gaps in the slot need to be repaired, which reduces construction efficiency. To address this, such as... Figure 1As shown in the figure, this utility model embodiment proposes a pre-embedded mounting bracket for a power and weak current box, used to install the box body 1, including:

[0025] Column 2 is installed along the height of the wall;

[0026] The mounting bracket 3 is connected to the electrical box body 1 and is fixedly provided with the mounting sleeve 301, which is fitted onto the column 2.

[0027] Fasteners are provided on the mounting sleeve 301 for fixing the bracket 3 to the column 2.

[0028] In the embodiments of this utility model, such as Figure 2 As shown, before constructing the wall, the column 2 is installed first. The column 2 is directly installed between the upper and lower beams, ensuring that the height of the column 2 is the normal floor height. When installing the column 2, a laser alignment instrument or a string line is used to ensure that the column 2 is perpendicular to the beam, guaranteeing the installation accuracy of the electrical box body 1. Depending on the installation height of the electrical box body 1, for example, a low-voltage box is generally 50cm from the ground, and a high-voltage box is generally 220cm from the ground, two fixing brackets 3 are installed on the column 2. The fixing brackets 3 are slidably mounted on the column 2 via mounting sleeves 301. After adjusting the corresponding dimensions of the two fixing brackets 3, they are fixed with fasteners. Finally, the electrical box body 1 is installed onto the fixing brackets 3 with screws. Then, the wall can be built normally, making the wall directly integrated with the electrical box body 1. The installation of the electrical box body 1 is completed simultaneously after the wall is built, which is very convenient. The fixing brackets 3 and the electrical box body 1 are detachably connected, and the mounting bracket structure can be reused multiple times.

[0029] Based on the above solution, in order to make fixing the mounting sleeve 301 more convenient and quick, such as Figure 2 As shown, the fastener is a limiting bolt 302, which is threadedly connected to the mounting sleeve 301. The end of the limiting bolt 302 abuts against the column 2. When the limiting bolt 302 is not abutting against the column 2, the limiting of the mounting sleeve 301 is released, allowing the mounting sleeve 301 to slide freely on the column 2. The installation position of the electrical box body 1 can be finely adjusted according to different floor heights. After adjustment, the limiting bolt 302 is rotated to abut against the column 2, thus fixing the mounting sleeve 301.

[0030] To enhance the fixing effect of the limiting bolt 302, the column 2 has several limiting holes 202 along its axial direction. The end of the limiting bolt 302 extends into one of the limiting holes 202. The limiting bolt 302 is screwed into the limiting hole 202, and the limiting hole 202 supports the limiting bolt 302, which further increases the stability of the fixing of the limiting bolt 302 and also prevents the limiting bolt 302 from scratching the surface of the column 2.

[0031] Specifically, such as Figure 2 As shown, the column 2 has a limiting groove 205, and the mounting sleeve 301 is slidably engaged with the limiting groove 205. Under the action of the limiting groove 205, the sliding trajectory of the mounting sleeve 301 can be limited, so that the mounting sleeve 301 can only slide along the limiting groove 205 and cannot rotate, thereby ensuring the installation accuracy of the electrical box body 1.

[0032] Based on the above solutions, such as Figure 1 and Figure 2 As shown, the column 2 also includes two fixing plates 4 located at both ends. Threaded rods 5 are slidably engaged at both ends of the column 2. The ends of the threaded rods 5 are connected to the corresponding fixing plates 4, and threaded sleeves 501 are rotatably provided at the ends of the column 2, with the threaded sleeves 501 threadedly connected to the threaded rods 5. Since the initial length of the column 2 is less than the floor height, when installing the column 2, only one end of the threaded sleeve 501 can be adjusted, causing the threaded sleeve 501 to rotate and extend the end of the threaded rod 5, allowing the fixing plate 4 to abut against the upper beam. When the threaded rod 5 at this end cannot reach the upper beam after adjustment, the threaded sleeve 501 at the other end can be adjusted until the fixing plates 4 at both ends of the column 2 abut against the upper and lower beams respectively. To ensure the stability of the column 2 after installation, the fixing plates 4 have several mounting holes 401, into which screws can be driven to complete the fixing of the fixing plates 4.

[0033] Based on the above solutions, such as Figure 3 As shown, the column 2 includes two interlocking splicing rods 201. One splicing rod 201 is provided with a connecting sleeve 203, and the other splicing rod 201 is provided with an installation groove 206. The connecting sleeve 203 passes through the installation groove 206, dividing the column 2 into two splicing rods 201. In use, the connecting sleeve 203 of one splicing rod 201 is directly inserted into the installation groove 206 of the other splicing rod 201 to complete the assembly. After use, it can be directly removed to reduce the size of the column 2, making it convenient for transportation and carrying.

[0034] Meanwhile, an elastic cable 6 is provided in the mounting groove 206, which is connected to another splicing rod 201. The mounting groove 206 has a rectangular groove 204 that extends through the splicing rod 201. The elastic cable 6 has a certain elasticity. When the two splicing rods 201 are connected, it can provide a certain pulling force to ensure the stability of the two splicing rods 201 after connection. When the two splicing rods 201 are separated, after forcefully separating the two splicing rods 201, the elastic cable 6 can be left in the rectangular groove 204 to keep the two splicing rods 201 connected together, while ensuring a small footprint.

[0035] Finally, it should be noted that the above embodiments are only used to illustrate the technical solutions of this utility model and are not intended to limit it. Although this utility model has been described in detail with reference to preferred embodiments, those skilled in the art should understand that modifications or equivalent substitutions can be made to the technical solutions of this utility model without departing from the spirit and scope of the technical solutions of this utility model, and all such modifications or substitutions should be covered within the scope of the claims of this utility model.
