[0016] In order to make the technical means, creative features, achieved purposes, and functions of the utility model easy to understand, the utility model will be further described below in conjunction with the specific embodiments.

[0017] Please refer to Figures 1-5 , a technical solution of a schematic diagram of a locomotive antenna with a protection structure according to the utility model: It includes a base 1, and a protection top cover 2 is snap-fitted on the top surface of the base 1. An antenna body 3 is arranged in the middle of the top surface of the base 1. A protection cover head 4 is threadedly connected to the top surface of the protection top cover 2. The base 1 includes a bottom plate 11. A plurality of installation threaded holes 12 are opened along the periphery of the bottom plate 11, and a protection card slot 13 is opened on the peripheral circle of the side of the bottom plate 11. The protection top cover 2 includes a top cover body 21. A protection card edge 22 matching the protection card slot 13 is arranged on the inner peripheral circle of the top cover body 21. A plurality of support columns 24 are vertically arranged on the peripheral circle of the bottom cavity of the top cover body 21. The bottom surfaces of the support columns 24 are in contact with the top surface of the bottom plate 11.

[0018] A wire arrangement through hole 14 is opened through the middle of the top surface of the bottom plate 11, and a wire arrangement through groove 15 is opened on one side of the lower hole edge of the wire arrangement through hole 14. The base 1 is made of aluminum.

[0019] A cap screw hole 23 is provided in the middle of the top surface of the top cover body 21, and sunken screw holes 25 corresponding to the respective mounting screw holes 12 are provided along the periphery of the top cover body 21. An inclined top 26 is provided along the periphery of the top surface of the top cover body 21. The top cover body 21 is made of plastic.

[0020] The protective cap head 4 includes a cap head main body 41. A threaded post 42 adapted to the cap screw hole 23 is provided in the middle of the bottom surface of the cap head main body 41. An arc top 43 is provided on the top surface of the cap head main body 41. A plurality of signal through holes 44 are obliquely opened upward in an annular array on the side of the cap head main body 41. A signal through groove 45 is provided in the middle of the threaded post 42. The signal through groove 45 communicates with each signal through hole 44. The protective cap head 4 is made of plastic.

[0021] Working principle:

[0022] When the base 1 is engaged with the protective top cover 2, the protective card slot 13 and the protective card edge 22 will be engaged at this time. During use, the cross section of the protective card slot 13 can support and protect the protective card edge 22, so that the left and right side surfaces of the top cover body 21 are not prone to cracking during high-speed locomotive driving. The design of the inclined top 26 on the top surface of the top cover body 21 reduces the wind resistance of the top cover body 21, thereby reducing the force on the left and right side surfaces of the top cover body 21. The support column 24 acts on the support of the inclined top 26 part, so that the inclined top 26 is not prone to cracking due to wind resistance force. The design of the protective cap head 4 enables the antenna main body 3 to transmit signals normally and can also protect the top cover body 21 so that the top cover body 21 will not get water.
