Technical Field

[0001] This utility model relates to the field of electric horn technology, and more specifically, to an electric horn. Background Technology

[0002] Electric horns produce sound through a mechanism of "electromagnetic drive - mechanical vibration - acoustic amplification," and their structural design (such as the shape of the horn tube and the material of the diaphragm) directly determines the volume, pitch, and durability. Some existing electric horns are quite long, making them inconvenient to carry in backpacks or suitcases. To facilitate the carrying of longer electric horns, we have designed a new type of electric horn. Utility Model Content

[0003] In order to overcome the shortcomings of the prior art, the present invention provides an electric horn to solve the problems mentioned in the background art.

[0005] As a preferred technical solution of this utility model, the limiting mechanism includes two limiting grooves, an insertion hole, and a sleeve. The two limiting grooves are respectively opened on both sides of the side wall of the electric horn body. The insertion hole is opened on one side of the collar. The sleeve is fixed to the side wall of the collar on the side of the insertion hole. A limiting rod is provided inside the sleeve. One end of the limiting rod passes through the insertion hole and is inserted into one of the limiting grooves. The other end of the limiting rod passes through the sleeve and is fixed with a pull ring. A spring is sleeved on the limiting rod. One end of the spring is fixed to the limiting rod, and the other end of the spring is fixed to the inner wall of the sleeve.

[0006] As a preferred embodiment of this utility model, a rubber pad is fixed to the inner wall of the collar.

[0007] As a preferred technical solution of this utility model, the sliding mechanism includes a sliding groove and a sliding plate. The sliding groove is formed on both sides of the electric horn body, and the sliding plate is fixed on both sides of the inner wall of the collar, and the sliding plate is slidably disposed in the sliding groove.

[0008] As a preferred technical solution of this utility model, a handle is fixed on one side of the lower part of the electric horn body, and the handle is covered with an anti-slip sleeve.

[0009] As a preferred technical solution of this utility model, the bottom of the grip is provided with a mounting plate, and mounting holes are provided on both sides of the mounting plate. The bottom of the grip is provided with a threaded groove, and a threaded rod is fixed on the top of the mounting plate. The threaded rod is inserted into the threaded groove, and the threaded rod and the threaded groove are connected by threads.

[0010] Compared with the prior art, the beneficial effects of this utility model are as follows:

[0011] This utility model uses a limiting mechanism to limit the collar, thereby fixing the horn mouth to the electric horn body. When it is necessary to retract the horn mouth, simply pull the limiting rod out of the limiting groove to move the collar, and then insert one end of the limiting rod into another limiting groove to retract the horn mouth, thus facilitating the carrying of the electric horn.

[0018] 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.

[0019] like Figures 1 to 4 As shown, this utility model provides an electric horn, including an electric horn body 1. One end of the electric horn body 1 is provided with a horn mouth 3. A collar 2 is fixed to the side wall of the horn mouth 3 and is sleeved on one end of the electric horn body 1. A rubber pad 4 is fixed to the inner wall of the collar 2. The rubber pad 4 can increase the sealing between the collar 2 and the electric horn body 1. A limiting mechanism 5 is connected between one side of the electric horn body 1 and the collar 2. The limiting mechanism 5 can limit the collar 2, thereby limiting the horn mouth 3. Sliding mechanisms are provided between both sides of the electric horn body 1 and the collar 2. The sliding mechanisms can limit the collar 2 horizontally.

[0020] The limiting mechanism 5 includes two limiting grooves 51, a socket 52, and a sleeve 53. The two limiting grooves 51 are respectively opened on both sides of the side wall of the electric horn body 1. The socket 52 is opened on one side of the collar 2. The sleeve 53 is fixed to the side wall of the collar 2 on the side of the socket 52. A limiting rod 54 is provided inside the sleeve 53. One end of the limiting rod 54 passes through the socket 52 and is inserted into one of the limiting grooves 51. By inserting one end of the limiting rod 54 into the limiting groove 51, the collar 2 can be limited. The other end of the rod 54 passes through the sleeve 53 and is fixed with a pull ring 56. A spring 55 is provided on the outer sleeve of the limiting rod 54. One end of the spring 55 is fixed to the limiting rod 54, and the other end of the spring 55 is fixed to the inner wall of the sleeve 53. When it is necessary to retract and move the flared mouth 3, simply pull the pull ring 56 to pull one end of the limiting rod 54 out of the limiting groove 51, then move the collar 2, and then insert one end of the limiting rod 54 into another limiting groove 51. In this way, the flared mouth 3 can be retracted and moved.

[0021] The sliding mechanism includes a slide groove 6 and a slide plate 7. The slide groove 6 is opened on both sides of the electric horn body 1, and the slide plate 7 is fixed on both sides of the inner wall of the collar 2. The slide plate 7 is slidably disposed in the slide groove 6. By sliding the slide plate 7 in the slide groove 6, the collar 2 can be horizontally limited.

[0022] The electric horn body 1 has a handle 8 fixed on one side below it. The handle 8 is covered with an anti-slip sleeve 9. The bottom of the handle 8 is provided with a mounting plate 10, and mounting holes 11 are provided on both sides of the mounting plate 10. The bottom of the handle 8 is provided with a threaded groove 12. A threaded rod 13 is fixed on the top of the mounting plate 10. The threaded rod 13 is inserted into the threaded groove 12 and is connected to the threaded groove 12 by threads. The handle 8 makes it easy to hold the electric horn body 1. The mounting holes 11 on both sides of the mounting plate 10 make it easy to install the electric horn body 1 on a bracket for use.

[0023] The working principle and usage process of this utility model are as follows: The limiting mechanism 5 can limit the collar 2, thereby limiting the horn mouth 3. When it is necessary to retract and move the horn mouth 3, simply pull the pull ring 56 to pull one end of the limiting rod 54 out of the limiting groove 51, then move the collar 2, and then insert one end of the limiting rod 54 into another limiting groove 51, so that the horn mouth 3 can be retracted and moved. By retracting the horn mouth 3, it is convenient to carry the electric horn.
