Detailed Description
In order that the present invention may be more clearly understood, a more particular description of the invention will be rendered by reference to specific embodiments thereof which are illustrated in the appended drawings.
Fig. 1 is a schematic structural diagram of a communication antenna sensing device according to an embodiment of the present application. The communication antenna sensing device comprises a shell 1, a cover plate 5 and a sealing gasket 6. The sealing gasket 6 is arranged in the mounting gap between the shell 1 and the cover plate 5, and can effectively fill the mounting gap between the shell 1 and the cover plate, so that the sealing performance of the device shell is ensured.
Specifically, the housing 1 is provided with a housing cavity 2 recessed into the housing 1 on the upper end surface thereof. Since the housing chamber 2 is formed by recessing the upper end surface of the housing 1 toward the inside of the housing 1, an opening 3 communicating with the housing chamber 2 is formed at the upper end surface of the housing 1. The components in the housing 1 are fixedly mounted in the accommodating chamber 2 through the opening 3. An annular limit flange 4 is fixedly arranged at the edge part of the upper end surface of the shell 1, the upper end surface of the annular limit flange 4 is higher than the upper end surface of the shell 1, and the limit flange 4 is surrounded outside the opening 3.
The cover plate 5 is detachably mounted on the upper end surface of the housing 1. The cover plate 5 matches the shape of the inside of the position-defining flange 4. When the cover plate 5 is installed on the upper end surface of the housing 1, the side wall of the cover plate 5 is attached to the inner wall of the position-limiting flange 4.
A ring-shaped placement groove 7 is further formed in a portion of the upper end surface of the housing 1 between the stopper flange 4 and the opening 3, and the placement groove 7 extends from the upper end surface of the housing 1 into the housing 1. A sealing gasket 6 is located in the standing groove 7. When apron 5 was installed on casing 1, seal ring 6 can fill the installation clearance between 1 up end of casing and the 5 lower terminal surfaces of apron with the terminal surface butt of apron 5 to guarantee sealing performance.
In this embodiment, the sealing washer 6 is a rubber washer, and has a certain elasticity. When subjected to pressure, can deform, ensuring that it can effectively fill the gap between the housing 1 and the cover plate 5.
A plurality of mounting holes 8 are formed in the cover plate 5, and the mounting holes 8 penetrate through the cover plate 5 in the thickness direction of the cover plate 5. The upper end surface of the shell 1 is correspondingly provided with mounting screw holes 9 with the same number as the mounting holes 8. When the cover plate 5 is covered on the upper end surface of the shell 1, each mounting hole 8 is aligned with the adjacent mounting screw hole 9, and the cover plate 5 can be fixedly connected with the shell 1 through the mounting bolt.
It can be understood that, because the cover plate 5 matches the inner shape of the position-limiting flange 4, when the cover plate 5 is installed on the upper end surface of the housing 1, the position-limiting flange 4 can be used as a positioning groove, when the side wall of the cover plate 5 is fitted with the inner wall of the position-limiting flange 4, the position of the cover plate 5 is fixed, and it can be ensured that the mounting hole 8 on the cover plate 5 is aligned with the mounting screw hole 9 on the housing 1, which facilitates the connection between the cover plate 5 and the housing 1.
In addition, when the cover plate 5 is mounted on the housing 1, the end surface of the cover plate 5 away from the housing 1 is flush with the upper end surface of the position-defining flange 4, i.e., the thickness of the cover plate 5 coincides with the thickness of the position-defining flange 4.
In addition to the above embodiments, the present invention may have other embodiments; all the technical solutions formed by adopting equivalent substitutions or equivalent transformations fall within the protection scope claimed by the present invention.
