Description

Technical Field

[0001] The utility model relates to an air horn solenoid valve, in particular to an air horn solenoid valve with good protection effect. Background Art

[0002] The air horn solenoid valve is a key control component in the air horn system installed on certain vehicles, especially large trucks, buses and construction machinery. The air horn solenoid valve includes an electromagnetic coil, an iron core, a seal, a plug, etc., and there are usually two interfaces on the valve body that are respectively connected to the air horn and the compressed air source.

[0003] It is very important to keep the inside of the air horn solenoid valve clean. The interfaces on the existing air horn solenoid valves are generally not sealed after leaving the factory. If dust, moisture and other impurities enter and accumulate inside the air horn solenoid valve during transportation and sale after leaving the factory, it is easy to block the small air passages inside the air horn solenoid valve and affect the normal passage of air flow, resulting in the air horn not being able to sound normally or the sound being weakened. Moreover, the impurities will wear or damage the seals inside the valve body, causing gas leakage. In addition, the plug of the existing air horn solenoid valve is thin and easy to bend, and the plug is directly installed on the air horn solenoid valve in a bare state. It is not only easy to be damaged during transportation, but also easy to get damp after installation, resulting in circuit damage.

[0004] In view of the above problems, we propose an air horn solenoid valve with good protection effect. Content of the Utility Model

Specific embodiments

[0030] The following will combine the attached Figures 1-5 in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the described embodiments are only some embodiments of the present invention, rather than all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those of ordinary skill in the art without creative efforts belong to the scope of protection of the present invention.

[0031] Embodiment:

[0032] Such as Figures 1 to 5As shown in the figure, a horn solenoid valve with good protection effect includes a mounting seat 11, which is installed in a vehicle through fasteners. An electromagnetic valve body 12 is installed on the mounting seat 11. Air intake pipes 13 for connecting a horn and a compressed air source are symmetrically arranged on the left and right sides of the electromagnetic valve body 12. A dust plug 14 is arranged on the air intake pipe 13. The dust plug 14 isolates the inside of the electromagnetic valve body 12 from the outside air, thereby preventing impurities in the air from entering the electromagnetic valve body 12 during the transportation and sale of the horn solenoid valve with good protection effect, causing damage to the internal structure of the electromagnetic valve body 12.

[0033] Before the horn solenoid valve with good protection effect leaves the factory, technicians drag the dust plug 14 and insert the dust plug 14 into the air intake pipe 13. Since the dust plug 14 is made of rubber and has good sealing performance, it can seal the air intake pipe 13, isolating the inside of the electromagnetic valve body 12 from the outside air, so as to prevent impurities in the air from entering the electromagnetic valve body 12 during transportation and sale and polluting the internal environment of the electromagnetic valve body 12.

[0034] Furthermore, in order to prevent the dust plug 14 from being lost during the transportation and sale of the horn solenoid valve with good protection effect, a rubber strip 15 is connected between the dust plug 14 and the mounting seat 11. When installing the horn solenoid valve with good protection effect, if the installation space is relatively compact, the rubber strip 15 is likely to interfere with other components. To this end, fixing mechanisms for fixing the dust plug 14 and the rubber strip 15 are symmetrically arranged on the left and right sides of the mounting seat 11.

[0035] The specific structure of the fixing mechanism is as follows: The fixing mechanism includes a slot 18. A shallow groove 28 with a side opening is formed on the front side of the mounting seat 11. The slot 18 is formed on the bottom surface of the shallow groove 28 and penetrates the mounting seat 11.

[0036] A threaded hole 19 is formed in the mounting seat 11. The threaded hole 19 is located above the slot 18. A threaded shaft 29 is threadedly connected in the threaded hole 19. A pressing plate 20 is rotatably connected to the threaded shaft 29.

[0037] Technicians lift the pressing plate 20 by rotating the threaded shaft 29, so as to facilitate the insertion of the dust plug 14 into the slot 18. Then, the dust plug 14 is inserted into the slot 18 through the shallow groove 28. Subsequently, the threaded shaft 29 is rotated to make the pressing plate 20 press on the dust plug 14, thereby achieving the purpose of fixing the dust plug.

[0038] Moreover, a limiting chute 21 is formed below the slot 18 on the mounting base 11. A limiting rod 22 is fixedly connected to the lower end of the pressing plate 20. The limiting rod 22 is slidably connected within the limiting chute 21. Through the above structure, it is ensured that the pressing plate 20 does not rotate, so as to ensure that the pressing plate 20 can stably press on the dust plug 14;

[0039] In addition, two elastic clips 27 are provided on the mounting base 11. The two elastic clips 27 are respectively located on the left side and the lower side of the slot 18. After the dust plug 14 is fixed, after the dust plug 14 is fixed, the rubber strip 15 is inserted into the two elastic clips 27, thereby restricting the rubber strip 15. After the air horn solenoid valve with good protection effect is installed, the rubber strip 15 will not shake and generate noise during the driving of the vehicle.

[0040] A plug connector 16 is provided on the solenoid valve body 12. The number of the plug connectors 16 is two. A protective shell 17 is installed outside the solenoid valve body 12. A protection mechanism for protecting the plug connector 16 is provided on the protective shell 17.

[0041] The specific structure of the protection mechanism is as follows: The protection mechanism includes a protection base 23. The protection base 23 is integrally formed on the protective shell 17. An upwardly open protection groove 24 is formed in the protection base 23. The end of the plug connector 16 extends into the protection groove 24. The protection base 23 covers the outside of the plug connector 16, so that after the plug connector 16 is inserted into the socket, it is not easy to contact with external water vapor, and the plug connector 16 is protected from being damaged by bumping during transportation or installation. Moreover, the waterproof grade of the plug connector 16 is upgraded from IP55 to IP57, thereby improving the waterproof performance of the plug connector 16.

[0042] Moreover, a resisting block 25 is integrally formed on the side wall of the protection groove 24. An inclined surface is formed at the upper end of the resisting block 25. The number of the resisting blocks 25 is two. A clamping hole 26 is formed on the lower side of each of the resisting blocks 25. One resisting block 25 and one clamping hole 26 form a complete snap structure.

[0043] When installing the air horn solenoid valve with good protection effect, the technician first inserts the plug connector 16 into the jack. During the insertion of the plug connector 16, the hook on the socket abuts against the inclined surface of the resisting block 25 and deforms and enters the protection groove 24. After entering the clamping hole 26, the hook rebounds and resets and is clamped in the clamping hole 26, thereby fixing the protection base 23 and making the connection between the plug connector 16 and the jack more stable;

[0044] Subsequently, the technician installs the mounting base 11 on the mounting platform using fasteners, and then connects the two connecting air pipes 13 to the air horn and the compressed air source respectively, thus completing the installation.

[0045] It should also be noted that the terms used in the present invention, such as "front", "rear", "vertical", "horizontal", etc., indicate the orientation or positional relationship based on the orientation or positional relationship shown in the drawings. These are only for the convenience of describing the present invention and simplifying the description, rather than indicating or implying that the device or element referred to must have a specific orientation, be constructed and operated in a specific orientation. Therefore, it should not be construed as a limitation on the protection scope of the present invention.

[0046] The above are only the preferred embodiments of the present invention and are not intended to limit the present invention. Any modifications, equivalent replacements, improvements, etc. made within the spirit and principle of the present invention shall be included within the protection scope of the present invention.
