[0016] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0017] Example: Figure 1-7 As shown, this utility model provides a small reversing horn, including a horn body 5 and a housing 1. The housing 1 is mounted on the horn body 5. A splash shield 2 is provided on the housing 1. The splash shield 2 includes a splash cover 21, which is fitted onto the outside of the housing 1. An opening 22 is provided on the side of the splash cover 21 away from the housing 1. A splash shield 23 is fixedly arranged side by side inside the opening 22. A baffle 24 is fixedly arranged symmetrically inside the opening 22, with the two baffles 24 located on both sides of the splash shield 23. A water guide groove 25 is provided on the inner wall of the splash cover 21, and a drain outlet 26 is provided on the inner wall of the water guide groove 25. A symmetrically arranged connecting component 27 is provided between the housing 1 and the splash shield 21. The baffles 24 and the splash shield 23 prevent most of the water from entering the splash shield 21. Inside the 1st section, water flows through the water guide channel 25 to the drain outlet 26 and is discharged, preventing water from accumulating inside the splash guard 21 and affecting the use of the horn. A mounting plate 3 is fixedly installed on the horn body 5, and a mounting hole 4 is opened on the mounting plate 3. The horn can be easily installed under the tricycle carriage through the mounting plate 3. A partition 28 is fixedly installed on the inner wall of the splash guard 21. The partition 28 is located on one side of the water guide channel 25. The partition 28 can block the water in the water guide channel 25. A mirror-distributed guide plate 29 is fixedly installed on the inner wall of the drain outlet 26. The two guide plates 29 are staggered and can guide water. The staggered distribution can prevent water from entering the splash guard 21 from the outlet. The guide plate 29 has a downward inclined structure, which can facilitate the guidance and discharge of water.

[0018] The connecting assembly 27 includes a connecting plate 271. The inner wall of the splash shield 21 has symmetrically distributed grooves 272. The connecting plate 271 is located in the grooves 272. A screw 276 is threadedly connected between the splash shield 21 and the connecting plate 271. The outer side of the outer shell 1 has symmetrically distributed guide grooves 274. One end of the guide groove 274 has a positioning groove 275. One end of the connecting plate 271 is inserted into the positioning groove 275. When the connecting plate 271 continues to move into the positioning groove 275, the elastic force drives the connecting plate 271 to insert into the positioning groove 275, thus installing the splash shield 21 on the outer shell 1. This facilitates the installation of the splash shield 21. The bottom end of the connecting plate 271 has a slope 273. The slope 273 facilitates the compression and deformation of the connecting plate 271. The connecting plate 271 has an L-shaped structure and is an elastic structure. The connecting plate 271 can move through elastic deformation.

[0019] Working principle: First, align the connecting plate 271 with the guide groove 274 and put the splash guard 21 onto the outer shell 1. At the same time, the pressure of the inner wall of the guide groove 274 on the inclined surface 273 causes the connecting plate 271 to undergo elastic deformation. When the connecting plate 271 continues to move into the positioning groove 275, the elastic force drives the connecting plate 271 to insert into the positioning groove 275, thereby installing the splash guard 21 on the outer shell 1, thus quickly installing the splash guard 21. Next, fix the mounting plate 3 to the underside of the tricycle through the mounting hole 4 with bolts, and connect the wire of the horn body 5 to the reversing light switch wire of the tricycle. When the tricycle splashes water while driving, most of the water is blocked from entering the splash guard 21 by the baffle 24 and splash guard 23 inside the opening 22. A small amount of water enters the splash guard 21 through the gap between the splash guard 23 and falls into the water guide channel 25. The water flows through the water guide channel 25 to the drain outlet 26 and is discharged from the drain outlet 26 through the guide plate 29, thus preventing water from accumulating inside the splash guard 21 and avoiding water splashing in and affecting the use of the horn.
