Description

Technical Field

[0001] This utility model relates to the technical field of power switch installation, and in particular to strip screws. Background Technology

[0002] As a core component of electronic devices, power switches are used to provide electrical energy to appliances. Existing power switches, such as the power switch wiring structure and power switch disclosed in utility model patent CN222654469U, and the power switch and socket box disclosed in utility model patent CN2618279Y, are all installed in junction boxes using screws.

[0003] However, during the installation process, it was found that the existing junction boxes have relatively deep threaded holes. In some junction boxes, such as those installed under cabinets or inside cabinets, it is inconvenient to observe and judge the position of the threaded holes when installing power switches. This makes it difficult to tighten the screws into the threaded holes of the junction box, which affects the installation efficiency and results in poor practicality. Therefore, there is an urgent need for a strip screw to improve the above problems. Utility Model Content

[0004] To solve the above-mentioned technical problems, this utility model provides a strip screw that improves the practicality of the strip screw by inserting the mounting structure into the limiting tube and aligning the mounting structure with the screw body. The operator uses a screwdriver to align the mounting structure with the screw body and screws it into the threaded hole of the junction box. Then, the mounting structure is removed from the limiting tube, the wiring switch is then attached to the junction box, and the power switch screw is passed through the power switch and tightened into the limiting tube to complete the installation of the power switch.

[0005] The present invention relates to a bar screw, comprising a screw body; and further comprising a limiting tube and a mounting structure, wherein the limiting tube is mounted on the screw body; The installation structure assists workers in installing the screw body into the threaded hole of the junction box; Insert the mounting structure into the limiting tube and align it with the screw body. The worker uses a screwdriver to align the mounting structure and screws the screw body into the threaded hole of the junction box. Then, remove the mounting structure from the limiting tube. Next, attach the wiring switch to the junction box, pass the power switch screw through the power switch, and tighten the power switch screw into the limiting tube to complete the installation of the power switch, thereby improving the practicality of the strip screw.

[0006] Preferably, the mounting structure includes a support column, a first connector, and a second connector, with the first connector and the second connector respectively installed at both ends of the support column; the first connector is inserted into the limiting tube and mated with the screw body, and the second connector is mated with the screwdriver. By rotating the screwdriver, the support column drives the screw body to rotate, and the screw body is installed into the threaded hole in the junction box.

[0007] Preferably, the bottom of the limiting tube is provided with multiple sets of brake pads; after the screw body is screwed into the threaded hole in the junction box, the multiple sets of brake pads abut against the top of the threaded hole, and the bottom of the multiple sets of brake pads is locked in the top of the threaded hole. When the power switch is tightened into the limiting tube, the pressure in the screw body and the threaded hole is reduced by the multiple sets of brake pads.

[0008] Preferably, the limiting tube has internal threads, and the top of the limiting tube has a hexagonal through hole with a diameter larger than that of the thread. This allows workers to use a hexagonal wrench to connect with the top of the limiting tube and screw the screw body into the threaded hole of the junction box, improving the applicability of the strip screw. Furthermore, the threads inside the limiting tube facilitate the limiting of the power switch screw screw screwed into the limiting tube.

[0009] Preferably, the top of the limiting tube is provided with multiple sets of inwardly guiding inclined surfaces; this facilitates the insertion of a connector, a hex wrench, or a power switch screw into the limiting tube.

[0010] Preferably, it also includes a sealing plug, which is installed on the top of the limiting tube; by installing the sealing plug, it prevents foreign matter from entering the limiting tube.

[0011] Compared with the prior art, the beneficial effects of this utility model are as follows: the mounting structure is inserted into the limiting tube and the mounting structure is aligned with the screw body. The operator uses a screwdriver to align with the mounting structure and screws the screw body into the threaded hole of the junction box. Then the mounting structure is removed from the limiting tube. After that, the wiring switch is snapped onto the junction box. Then the power switch screw is passed through the power switch and tightened into the limiting tube to complete the installation of the power switch, thereby improving the practicality of the strip screw.
