Description

Technical Field

[0001] The present invention relates to the field of communication technologies, and particularly to a ceiling-mounted installation bracket for a pRRU. Background Art

[0002] A pRRU is a miniaturized, low-power, and low-consumption microcellular base station, mainly used to solve the indoor wireless coverage problem in specific areas, such as within a certain building (office building, shopping mall, railway station, stock exchange, etc.).

[0003] The ceiling-mounted installation of a pRRU has always been a difficult problem that engineers cannot avoid. A good installation bracket can not only improve the safety of the device but also save a large amount of manpower and financial resources.

[0004] Most of the traditional ceiling-mounted installations of pRRUs are carried out by means of screws or bolts, but the installation structure is complex and requires the use of special tools for installation, which brings great inconvenience to the installers. There are also some installation methods using magnetic adsorption on the market, but for heavier devices, the connection reliability of the magnets is difficult to guarantee. When encountering a slightly stronger vibration, the ceiling-mounted structure may fall off, posing a safety hazard. To ensure that it does not fall off but remains attached, a relatively complex anti-falling device needs to be designed, thereby increasing the production cost and also bringing inconvenience to the installation. Summary of the Invention

[0005] The purpose of the present invention is: in view of the above problems existing in the traditional ceiling-mounted installation bracket for a pRRU, to provide a pRRU ceiling-mounted installation bracket with a simple structure, simple operation, and relatively low production cost.

[0006] To achieve the above purpose, the technical solution adopted by the present invention is: a pRRU ceiling-mounted installation bracket,

[0007] comprising a connecting frame and a fixing frame; the connecting frame is connected to the pRRU device to be ceiling-mounted; the fixing frame is fixedly connected to the ceiling; the upper surface of the connecting frame is provided with a plurality of irregular cylinders, and the irregular cylinders include three cylinders with different diameters; the fixing frame is provided with a fixing groove matching the irregular cylinders, the fixing groove includes circular grooves with different diameters at both ends and an annular groove in the middle, and the connecting frame and the fixing frame are rotationally combined through the irregular cylinders and the fixing groove.

[0008] As a preferred embodiment of the present invention, the three cylinders with different diameters are, in sequence along the direction away from the upper surface of the connecting frame, a first cylinder, a second cylinder, and a third cylinder, and the diameter of the first cylinder < the diameter of the second cylinder < the diameter of the third cylinder.

[0009] As a preferred embodiment of the present invention, the circular grooves with different diameters at both ends are set as the first circular groove and the second circular groove, and the diameter of the first circular groove > the diameter of the second circular groove > the diameter of the annular groove.

[0010] As a preferred embodiment of the present invention, the diameter of the third cylinder is slightly larger than the diameter of the second circular groove and slightly smaller than the diameter of the first circular groove; the diameter of the second cylinder is slightly larger than the diameter of the annular groove and slightly smaller than the diameter of the second circular groove; the diameter of the first cylinder is slightly smaller than the diameter of the annular groove.

[0011] As a preferred embodiment of the present invention, the two ends of the fixing frame are also provided with bending parts for fixedly connecting with the suspended ceiling.

[0012] As a preferred embodiment of the present invention, the height of the bending part is greater than the height of the third cylinder.

[0013] As a preferred embodiment of the present invention, the connecting frame is made of nylon PA46 by die casting.

[0014] As a preferred embodiment of the present invention, the fixing frame (2) is bent from galvanized steel sheet SECC.

[0015] Compared with the prior art, the beneficial effects of the present invention are as follows:

[0023] The preferred embodiments of the present invention will be described in more detail below with reference to the accompanying drawings. Although the preferred embodiments of the present invention are shown in the drawings, it should be understood that the present invention can be implemented in various forms and should not be limited by the embodiments set forth herein.

[0024] As Figures 1-3 shown, a ceiling-mounted bracket for pRRU includes a connecting frame 1 and a fixing frame 2; the connecting frame 1 can be fixed to the equipment that needs to be ceiling-mounted; the fixing frame 2 can be connected and fixed to the ceiling or ceiling; four cylinders with three different heights and different diameters are provided on the surface of the connecting frame; the first layer is a cylinder with a diameter of 8.5 mm and a height of 9 mm, the second layer is a cylinder with a diameter of 10 mm and a height of 4.5 mm; the third layer is a cylinder with a diameter of 15 mm and a height of 4 mm; four fixing grooves are formed on the surface of the fixing frame 2, and the circular grooves with a diameter of 17 mm at both ends are connected to the circular groove with a diameter of 12 mm through an annular groove with a diameter of 9.5 mm. The connecting frame 1 and the fixing frame 2 are rotationally combined and fixed by the weight of the equipment itself.

[0025] Preferably, the connecting frame 1 is die-cast from nylon PA46.

[0026] Preferably, the fixing frame 2 is bent from galvanized steel sheet SECC.

[0027] After passing the third-layer cylinder of the connecting frame 1 upward through the groove with a diameter of 17 mm on the surface of the fixing frame 2, continue to move upward until the first-layer cylinder of the connecting frame 1 passes through the groove with a diameter of 17 mm on the surface of the fixing frame 2, and then rotate the connecting frame 1 along the annular groove with a diameter of 9.5 mm of the fixing frame 2. After rotating to the circular groove with a diameter of 12 mm, lower the connecting frame 1. At this time, the connecting frame 1 will fall downward by relying on the weight of the pRRU device itself. When falling, the second-layer cylinder of the connecting frame 1 is in the groove with a diameter of 12 mm on the surface of the fixing frame 2. At this time, the diameter of the third-layer cylinder of the connecting frame 1 is 15, which is larger than the groove with a diameter of 12 mm of the fixing frame 2, so the pRRU device will not fall. Also, because the diameter of the second-layer cylinder of the connecting frame 1 is 10 mm at this time, which is larger than the annular groove with a diameter of 9.5 mm on the surface of the fixing frame 2, the pRRU device will not shake left and right. At this time, the pRRU device is completely fixed.

[0028] The foregoing describes one embodiment of the present invention. The above description is exemplary and not exhaustive, and is not limited to the disclosed embodiments. Many modifications and variations are obvious to those of ordinary skill in the art without departing from the scope and spirit of the described embodiments.
