Description

Technical Field

[0001] The utility model relates to the technical field of locomotive whistles, and specifically relates to a locomotive whistle that is convenient to install. Background Technique

[0002] The locomotive whistle has two functions. One is as a liaison signal, which has gradually been replaceable by wireless communication signals; the other is as a warning signal, mainly to warn pedestrians, vehicles and line workers in front of the locomotive during operation, playing a protective role.

[0003] For example, the Chinese patent whistle with the patent application number 201921067514.3. This patent emits sound through a horn. The frequency of deformation and recovery of the sound - generating structure forms the sound - generating frequency of the whistle. By adjusting the distance that the frequency - modulation seat extends into the open cavity, the space between the sound - generating structure and the frequency - modulation seat is changed, so that the deformation amount of the sound - generating structure towards the second air chamber is different. The time for the sound - generating structure to return to its original shape changes with the size of the second air chamber space, thereby changing the frequency of the whistle.

[0004] However, when the above - mentioned patent is used, it needs to be installed by using bolts or welding, resulting in low installation efficiency and inconvenient disassembly, thus seriously affecting the replacement and maintenance efficiency of the whistle. Content of the Utility Model

The top of the installation base 1 is fixedly connected to a chassis 2 through a rotary locking mechanism. A whistle main body 3 is installed on the top of the chassis 2. Multiple buffer mechanisms are arranged inside the installation base 1 and below the chassis 2.

[0033] By adopting the above technical solution, the device can sound a warning through the whistle main body 3, thus greatly improving the practicability of the device.

[0034] In the embodiment of the present application, as Figure 2 and Figure 4 shown, the rotary locking mechanism includes fixing plates 4 installed on both sides of the chassis 2 and sliding grooves 5 opened on the inner walls of both sides of the installation base 1. Openings 6 and locking holes 7 are respectively opened at both ends of the sliding groove 5. An elastic locking rod 8 is installed inside the fixing plate 4.

[0035] By adopting the above technical solution, the device can quickly fix and install the whistle main body 3 through the rotary locking mechanism, thus greatly facilitating the installation and disassembly of the whistle main body 3 by the operator, and further greatly improving the replacement and maintenance efficiency of the whistle main body 3 by the maintenance personnel.

[0036] In the embodiment of the present application, as Figures 2-3 shown, the buffer mechanism includes a sliding rod 10 fixedly connected to the inner wall of the installation base 1 and a buffer plate 9 movably arranged inside the installation base 1. A slider 11 is movably connected to the outer surface of the sliding rod 10. The top of the slider 11 is hinged to a connecting rod 12. The top of the connecting rod 12 is hinged to the chassis 2. A damping shock-absorbing spring 13 is arranged on the outer surface of the sliding rod 10 between the slider 11 and the inner wall of the installation base 1.

[0037] By adopting the above technical solution, the device can effectively reduce the vibration amplitude generated by the whistle main body 3 during the locomotive driving process through the buffer mechanism, thereby avoiding damage or loosening of the internal parts of the whistle main body 3 due to excessive vibration amplitude, and further greatly improving the installation stability and safety of the whistle main body 3.

[0038] In the embodiment of the present application, as Figure 5 shown, the elastic locking rod 8 includes a locking outer rod 801. A locking spring 802 is fixedly connected to the bottom of the inner cavity of the locking outer rod 801. A locking inner rod 803 is fixedly connected to the top of the locking spring 802.

[0039] By adopting the above technical solution, by utilizing the elastic action of the locking spring 802, the locking effect of the device is better.

[0040] Optionally, a buffer pad is fixedly connected to the top of the buffer plate 9.

[0041] By adopting the above technical solution, the buffering effect of the device is better by utilizing the buffering effect of the buffer pad.

[0042] In the embodiment of the present application, as Figure 3 shown, a total of four sets of buffer mechanisms are provided, and the four sets of buffer mechanisms are distributed in a circular array.

[0043] By adopting the above technical solution, the buffering effect of the device is better by utilizing the coordinated cooperation of multiple sets of buffer mechanisms.

[0044] In the embodiment of the present application, as Figure 5 shown, a sponge sleeve is fixedly connected to the top of the locking inner rod 803.

[0045] By adopting the above technical solution, the sponge sleeve makes it more comfortable for the operator to press.

[0047] By adopting the above technical solution, the baffle can prevent the slider 11 from sliding off the sliding rod 10.

[0048] During use, the operator can first press the locking inner rod 803 to retract it into the locking outer rod 801 by compressing the locking spring 802, and then insert the fixing plate 4 into the opening 6. When the fixing plate 4 reaches the lowest end, rotate the chassis 2 so that the fixing plate 4 can slide along the sliding groove 5. When the fixing plate 4 drives the locking outer rod 801 to move to the position of the locking hole 7, the locking inner rod 803 will quickly pop out under the elastic action of the locking spring 802, so that the chassis 2 can be quickly fixed to the mounting base 1, which greatly facilitates the operator to install and disassemble the bagpipe main body 3, and thus greatly improves the replacement and maintenance efficiency of the bagpipe main body 3 by the maintenance personnel. When the vehicle is subjected to severe vibration during driving, the chassis 2 will vibrate to a certain extent. When the chassis 2 vibrates, it will drive the slider 11 to slide along the sliding rod 10 through the connecting rod 12. When the slider 11 slides, it will squeeze the damping shock-absorbing spring 13, so that the elastic action of the damping shock-absorbing spring 13 can effectively reduce the vibration amplitude of the chassis 2, and thus can avoid damage or loosening of the internal parts of the bagpipe main body 3 due to excessive vibration amplitude, thereby greatly improving the installation stability and safety of the bagpipe main body 3.
