For example, "connected" can be fixedly connected, or can be detachably connected, or integrally connected; can be mechanically connected, or can be electrically connected; can be directly connected, or can be indirectly connected through an intermediate medium; or can be the communication between two elements. For those skilled in the art, the specific meaning of the above terms in the present application can be understood according to the specific circumstances.

[0024] Embodiment one: reference Figures 1-4The excavator air conditioner air door shaft shown comprises a connecting shell 13, which plays a protective and supporting role for the internal structure, can prevent external sundries from directly contacting the internal key components, and ensures that the air door shaft operating environment is relatively safe. The top of the connecting shell 13 is provided with a closing assembly for closing operation on the top of the connecting shell 13, so as to avoid sundries from entering the inside of the connecting shell 13 from the top and affecting the work of the air door shaft. The closing assembly comprises a fixed frame 17 fixedly connected with the connecting shell 13, which provides a mounting base for the entire closing assembly and is stably connected on the connecting shell 13 to ensure that the subsequent components can normally work in cooperation. The side wall of the fixed frame 17 is rotationally connected with a rotating disc 4, which controls the shutter 5 through rotation, thereby controlling the opening and closing state of the closing assembly. The top of the fixed frame 17 is fixedly connected with a plurality of fixed columns 11, which are used to support and rotationally connect the shutter 5, so that the shutter 5 can rotate around the fixed columns 11. The side wall of the fixed column 11 is rotationally connected with the shutter 5, which can cover or open the top of the connecting shell 13 when rotating, thereby playing a role in blocking sundries from entering. The side wall of the shutter 5 is fixedly connected with a connecting block 10, which connects the shutter 5 with the moving column 9, so that the rotation of the shutter 5 can drive the moving column 9 to move synchronously. One end of the connecting block 10 is fixedly connected with the moving column 9, which slides in the limiting groove 8 to guide the rotation track of the shutter 5, so as to ensure that the shutter 5 can be accurately opened and closed. The top of the rotating disc 4 is provided with a plurality of limiting grooves 8, and each moving column 9 slides in each limiting groove 8. The limiting groove 8 limits the movement path of the moving column 9, thereby accurately controlling the rotation angle and position of the shutter 5, and realizing effective closing and opening of the top of the connecting shell 13.

[0025] Example two: refer to Figures 1-4, based on the same idea as in the above embodiment one, the embodiment also proposes that the bottom of the fixed frame 17 is fixedly connected with the connecting shell 13, and the fixed frame 17 provides stable support and connection basis for the connecting shell 13, so that the connecting shell 13 is fixed in position in the overall structure. The bottom of the connecting shell 13 is fixedly connected with the upper shell 1, and the connecting shell 13 plays a role in linking the fixed frame 17 and the upper shell 1, ensuring the coherence of the entire structure. The inside of the upper shell 1 is provided with an upper shaft 12, and the upper shell 1 plays a role in protecting and positioning the upper shaft 12, limiting the path of the upper shaft 12 inside it. The upper shaft 12 slides inside the fixed frame 17, the connecting shell 13 and the upper shell 1, and the upper shaft 12 adjusts its position by sliding in these components to meet the needs of the damper shaft in different working states. The upper shaft 12 penetrates the fixed frame 17, the connecting shell 13 and the upper shell 1, and the design of the upper shaft 12 ensures that it can operate stably under the cooperation of various components and transmit power, etc. The side wall of the upper shell 1 is fixedly connected with the moving plate 14, and the moving plate 14 can move with the movement of the upper shaft 12, playing a role in assisting the movement of the upper shaft 12 and supporting the spring 15. The moving plate 14 is inside the upper shell 1, and the inside position is set so that it can effectively cooperate with the structural relationship between the upper shaft 12 and the upper shell 1. The side wall of the upper shaft 12 is fixedly connected with the push rod 3, which is used to transmit the moving force of the upper shaft 12 and can push related components to achieve specific functions, such as pushing the damper blades. The push rod 3 slides in the side wall of the connecting shell 13, and the design of sliding in the side wall allows the push rod 3 to function within a limited space without affecting the protection of the internal structure by the connecting shell 13. The outside of the upper shaft 12 is sleeved with the spring 15, which provides elastic force. When external force acts on the upper shaft 12 to make it move, the spring 15 can push the upper shaft 12 back to its original position. One end of the spring 15 is fixedly connected with the bottom of the moving plate 14, and the other end of the spring 15 is fixedly connected with the inside bottom of the upper shell 1, which ensures that the spring 15 can effectively exert force on the upper shaft 12. The bottom of the upper shell 1 is fixedly connected with the lower shell 2, and the fixed connection of the upper shell 1 and the lower shell 2 forms a relatively closed space, providing a stable installation environment for the lower shaft 6. The inside of the lower shell 2 is provided with a lower shaft 6, and the lower shell 2 plays a role in protecting and positioning the lower shaft 6, so that the lower shaft 6 can operate stably. The bottom of the upper shaft 12 is fixedly connected with the clamping plate 16, which is used to connect with the lower shaft 6 to realize the cooperation of the upper shaft 12 and the lower shaft 6. The top of the lower shaft 6 is provided with a connecting groove 7 matched with the clamping plate 16, and the connecting groove 7 is matched with the clamping plate 16. The cooperation of the two can make the upper shaft 12 and the lower shaft 6 tightly connected, ensuring the stability of power transmission.

[0026] The utility model discloses a working principle: use this axle, first staff presses push rod 3 downward, and makes the upper axle 12 through the moving plate 14 extrude spring 15, and spring 15 is in compression state, until the card plate 16 and the connection groove 7 are engaged, complete the splicing of upper axle 12 and lower axle 6, when rotating the rotating disc 4, and the movement column 9 is limited to limit the movement of position slot 8, make multiple baffle 5 with fixed column 11 as the pivot deflection, and fixed frame 17 is completely blocked, when upper axle 12 and baffle 5 are opposite, and the card plate 16 and the connection groove 7 are mutually engaged and are in stable state.

[0027] Finally, it should be noted that: the above only for the preferred embodiments of the utility model and does not limit the utility model, although the utility model has been described in detail with reference to the foregoing embodiments, for the person skilled in the art, it still can modify the technical scheme recorded in the foregoing each embodiment, or equivalent replacement to part technical feature, any modification, equivalent replacement, improvement etc. that is made within the spirit and principle of the utility model, should be included in the protection scope of the utility model.
