[0021] The following will be combined with the drawings in the embodiments of the utility model to clearly and completely describe the technical solutions in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments in the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.

[0022] The utility model provides Figure 1-3 A waterproof broadband double-ridged horn antenna shown includes a broadband double-ridged horn antenna body 101, a waterproof mechanism and a positioning mechanism. A feeding head is provided at the end of the broadband double-ridged horn antenna body 101. The main structure of the broadband double-ridged horn antenna body 101 and the feeding head in the present application is the same as the antenna disclosed in the comparative patent (publication number: CN220066077U and CN210723347U). Its working principle and usage method will not be described in detail here.

[0023] Among them, the waterproof mechanism includes a waterproof resin plate 102 inserted into the inside of the broadband double-ridged horn antenna body 101. The waterproof resin plate 102 is used to prevent water from entering the inner cavity of the broadband double-ridged horn antenna body 101, thereby preventing water from entering the inner cavity of the broadband double-ridged horn antenna body 101 and causing damage to the broadband double-ridged horn antenna body 101, thereby improving the stability of the use of the broadband double-ridged horn antenna body 101 and extending the service life of the broadband double-ridged horn antenna body 101.

[0024] In a preferred embodiment, the positioning mechanism includes a positioning hole 202 symmetrically opened on the inner wall of the broadband double-ridged horn antenna body 101, the inner wall of the positioning hole 202 is movably connected with a positioning plate 201, a connecting mechanism is arranged between the positioning plate 201 and the waterproof resin plate 102, a sealing mechanism is arranged between the waterproof resin plate 102 and the broadband double-ridged horn antenna body 101, the positioning hole 202 is arranged as a single opening, the depth of the positioning hole 202 is less than the wall thickness of the broadband double-ridged horn antenna body 101, and the positioning hole 202 arranged as a single opening makes the positioning hole 202 not penetrate the broadband double-ridged horn antenna body 101. The wall of the horn antenna body 101 will not have a significant impact on the signal transmission of the broadband double-ridged horn antenna body 101, thereby ensuring that the broadband double-ridged horn antenna body 101 can be used stably, and the waterproof resin plate 102 is directly inserted into the broadband double-ridged horn antenna body 101 from the opening of the broadband double-ridged horn antenna body 101, and then the positioning plate 201 is inserted into the positioning hole 202 to position the waterproof resin plate 102. The large opening of the broadband double-ridged horn antenna body 101 has a larger operating space, thereby improving the convenience of disassembly and assembly of the waterproof resin plate 102.

[0025] Among them, the connecting mechanism includes a fixing box 301 fixedly connected to the front side of the waterproof resin plate 102, and a slide groove 302 is arranged on one side of the fixing box 301. The slide groove 302 is arranged to be connected with openings at both ends. The outer walls of the two positioning plates 201 are slidably connected to the inner walls of the slide groove 302. The interior of the fixing box 301 is provided with an extrusion mechanism. The positioning plate 201 slides in the slide groove 302, so that after the positioning plate 201 is inserted into the positioning hole 202, the position of the waterproof resin plate 102 can be fixed through the connection of the fixing box 301, so that the waterproof resin plate 102 can be used stably, thereby improving the working stability of the waterproof resin plate 102.

[0026] Wherein, the squeezing mechanism includes a spring 401 arranged inside the fixing box 301, and the spring 401 is arranged between the two positioning plates 201. The front of the fixing box 301 is provided with an unlocking mechanism. Through the elastic action of the spring 401, the two ends of the spring 401 squeeze the two positioning plates 201 respectively, so that after the two positioning plates 201 are inserted into the positioning holes 202, if the positioning plates 201 are not subjected to a relatively large reverse force that is opposite to the elastic force of the spring 401, the positioning plates 201 will not automatically separate from the positioning holes 202, thereby further improving the working stability of the waterproof resin plate 102. At the same time, under the setting of the spring 401, and the maximum distance between the two positioning plates 201 is less than the maximum width of the inner cavity of the broadband double-ridged horn antenna body 101, the waterproof resin plate 102 can be inserted into the broadband double-ridged horn antenna body 101 for installation, even when there is In the case of two protruding positioning plates 201, the waterproof resin plate 102 can also be directly inserted into the broadband double-ridged horn antenna body 101, and then as the waterproof resin plate 102 moves, the inclined inner wall of the broadband double-ridged horn antenna body 101 will squeeze the positioning plate 201, so that the positioning plate 201 moves into the slide groove 302, and the positioning plate 201 will squeeze the spring 401 until the waterproof resin plate 102 drives the positioning plate 201 to move to the position of the positioning hole 202. At this time, the squeezed spring 401 releases the elastic force, moves the positioning plate 201 and inserts it into the positioning hole 202, and the installation of the waterproof resin plate 102 can be completed. During the installation of the waterproof resin plate 102, the staff only needs to perform a step of inserting the waterproof resin plate 102 into the broadband double-ridged horn antenna body 101, thereby improving the convenience of installing the waterproof resin plate 102.

[0027] Among them, the unlocking mechanism includes a connecting groove 501 symmetrically opened on the front side of the fixing box 301, the interior of the connecting groove 501 is connected to the interior of the fixing box 301, and the inner wall of the connecting groove 501 is slidably connected with a slider 502, and the back side of the slider 502 is fixedly connected to the front side of the positioning plate 201. By fixing the slider 502 to the positioning plate 201, when the waterproof resin plate 102 needs to be disassembled, it is only necessary to move the slider 502 to move the positioning plate 201 until the positioning plate 201 is separated from the positioning hole 202, and the waterproof resin plate 102 in the broadband double-ridge horn antenna body 101 can be removed. At the same time, the slider 502 protrudes from the fixing box 301, and the positioning plate 201 can be moved on the front side of the fixing box 301, which improves the convenience of operating the positioning plate 201 and also provides the convenience of disassembling the waterproof resin plate 102.

[0028] Among them, the sealing mechanism includes a rubber strip 601 attached to the outer wall of the waterproof resin plate 102, and the outer wall of the rubber strip 601 is arranged with an interference fit with the inner wall of the broadband double-ridged horn antenna body 101. When the waterproof resin plate 102 is installed, after the waterproof resin plate 102 is inserted into the broadband double-ridged horn antenna body 101, as the waterproof resin plate 102 continues to move, the rubber strip 601 will be pressed against the inner wall of the broadband double-ridged horn antenna body 101 and squeezed until the positioning plate 201 is inserted into the positioning hole 202. At this time, the rubber strip 601 is in a squeezed state, so that the gap between the waterproof resin plate 102 and the broadband double-ridged horn antenna body 101 is sealed by the squeezed rubber strip 601, so as to prevent water from entering the inner cavity of the broadband double-ridged horn antenna body 101 through the gap between the rubber strip 601 and the waterproof resin plate 102, thereby improving the waterproof effect of the waterproof resin plate 102.

[0029] Finally, it should be noted that the above is only a preferred embodiment of the present invention and is not intended to limit the present invention.
