Description

Technical Field

[0001] This utility model relates to the technical field of sprinkler head matching base bracket, specifically a sprinkler head matching base bracket for color steel plate ceiling. Background Technology

[0002] A cleanroom is a well-sealed space where parameters such as air cleanliness, temperature, humidity, pressure, and noise are controlled as needed. Fire safety must be considered during the design and installation of a cleanroom to ensure the safety of people inside. When installing fire sprinkler systems, especially fire sprinkler heads, holes need to be drilled in the steel ceiling panels to ensure the sprinkler heads are exposed. A matching base bracket must be used for installation of the sprinkler heads.

[0003] A Chinese patent (CN21850117U) discloses a sprinkler head support bracket for a color steel ceiling. The bracket includes a frame with an extended double-ended internal threaded tube inside. A color steel ceiling is located at the bottom of the frame, and the bottom end of the extended double-ended internal threaded tube penetrates the ceiling and extends to the bottom surface of the ceiling. This invention connects the sprinkler head to the sprinkler branch pipe by first installing the frame and extended double-ended internal threaded tube onto the color steel ceiling, then aligning the bottom end of the sprinkler branch pipe with the upper thread of the extended double-ended internal threaded tube and screwing it in, and finally aligning the hollow tube on the interior decorative panel with the lower thread of the extended double-ended internal threaded tube and screwing it in. Finally, the three bolts on the frame are tightened for use. The installation is convenient and quick, can be prefabricated in the factory, and reduces construction time. During the installation of the above-mentioned device, it is necessary to disassemble one of the ceiling color steel panels, drill holes, install the frame on the outer wall of the color steel panel, and then install the ceiling color steel panel together with the adjacent color steel panels. The process of disassembling and installing the color steel panels is cumbersome and inconvenient to use. Therefore, it is necessary to propose a matching base bracket for the sprinkler head for color steel panel ceilings to solve the above problems. Utility Model Content

[0004] The purpose of this utility model is to provide a base bracket for a sprinkler head used in color steel plate ceilings. It features that the sprinkler head can be installed without disassembling the color steel plate ceiling, and is simple to operate and convenient to use.

[0005] To achieve the above objectives, this utility model provides the following technical solution: a base bracket for a sprinkler head used in a color steel plate ceiling, comprising a color steel plate body and a sprinkler pipe. A sleeve frame is fixedly connected to the outer wall of the sprinkler pipe. A spring fitted onto the outer wall of the sprinkler pipe is fixedly connected to the lower end of the sleeve frame. A drive ring fitted onto the outer wall of the sprinkler pipe and movably connected to the sprinkler pipe is fixedly connected to the other end of the spring. Two symmetrically distributed pull rods are fixedly connected to the lower end of the drive ring. Two symmetrically distributed first grooves are formed on the outer wall of the sleeve frame. A first connecting rod is movably connected to the interior of each of the two first grooves via a rotating shaft. Two symmetrically distributed second grooves, corresponding to the two first grooves, are formed on the outer walls of the two drive rings. A second connecting rod is movably connected to the interior of each of the two second grooves via a rotating shaft. The two second connecting rods are movably connected to the two first connecting rods via rotating shafts. A threaded pipe is fixedly connected to the outer wall of the sprinkler pipe. A limiting sleeve located below the color steel plate body is threadedly connected to the outer wall of the threaded pipe.

[0006] The lower end of the sleeve frame is fixedly connected to a limiting rod located directly above the drive ring.

[0007] To facilitate the installation of the sprinkler pipe, as a preferred embodiment of the sprinkler head supporting base bracket for color steel plate ceilings according to this utility model, a through hole is provided at the upper end of the color steel plate body.

[0008] To facilitate the passage of the tie rods, as a preferred embodiment of the sprinkler head base bracket for color steel plate ceilings according to this utility model, the upper end of the threaded tube has two through holes that are symmetrically distributed front and back and fitted onto the outer walls of the two tie rods.

[0009] To facilitate limiting the lower end of the color steel plate body, in a preferred embodiment of the sprinkler head supporting base bracket for color steel plate ceiling according to this utility model, the lower end of the drive ring abuts against the upper end of the color steel plate body, and the upper end of the limiting sleeve abuts against the lower end of the color steel plate body.

[0010] To ensure that the sleeve support and drive ring pass through the through hole, as a preferred embodiment of the sprinkler head base bracket for color steel plate ceilings according to this utility model, the size of the through hole is larger than the size of the sleeve support and drive ring.

[0011] To prevent the tie rods from coming loose through the holes, as a preferred embodiment of the sprinkler head base bracket for color steel plate ceilings according to this utility model, the lower ends of both tie rods are fixedly connected to limit blocks.

[0012] Compared with the prior art, the beneficial effects of this utility model are as follows: This utility model, through the cooperation of the pull rod, drive ring, and spring, unfolds the first and second connecting rods, allowing the spray pipe, sleeve frame, and the first and second connecting rods to pass through the through hole and move to the upper end of the color steel plate body. The pull rod is pushed in the opposite direction, compressing the spring while simultaneously causing the upper end of the drive ring to abut against the lower end of the limiting rod. At this time, the first and second connecting rods are folded and supported on the upper end of the color steel plate body. Then, the limiting sleeve abuts against the lower end of the color steel plate body, simultaneously limiting the drive ring and installing the spray pipe and the color steel plate body together. This achieves the goal of installing the spray head through a telescopic bracket without disassembling the color steel plate ceiling, making operation simple and convenient.
