[0004] In order to solve the above technical problems, the utility model provides the following technical solutions:

[0005] An extremely simple elevation and rotation structure for a fire fighting gun of the utility model includes a flange ball head seat, an adjusting pipe and a threaded ball head seat; butt ball heads for docking with the flange ball head seat and the threaded ball head seat are arranged at both ends of the adjusting pipe; an elevation and rotation mechanism is arranged among the adjusting pipe, the flange ball head seat and the threaded ball head seat.

[0006] As a preferred technical solution of the utility model, a hinge block is arranged on the adjusting pipe, an electric push rod is installed between the flange ball head seat and the hinge block, a first gear is arranged on the adjusting pipe, and a second gear meshing with the first gear is arranged on the flange ball head seat; the second gear is fixedly connected with the outer wall of the flange ball head seat.

[0007] As a preferred technical solution of the utility model, a third gear is arranged on the threaded ball head seat, and the third gear is fixedly connected with the outer wall of the threaded ball head seat; a fourth gear drivingly connected with the third gear is arranged on the adjusting pipe; the fourth gear and the first gear are connected through a connecting shaft.

[0008] As a preferred technical solution of the utility model, a cage is fixed on the adjusting pipe, and an intermediate gear meshing with the third gear and drivingly meshing with the third gear is fixed on the cage.

[0009] As a preferred technical solution of the present utility model, the connection between the connecting shaft and the adjusting pipe is connected through a sealing structure.

[0010] As a preferred technical solution of the present utility model, sealing rings for sealing the connection of the docking ball head are provided on the flange type ball head seat and the threaded type ball head seat.

[0011] The beneficial effects of the present utility model are:

[0012] When the extremely simple elevation and rotation structure for a fire fighting cannon performs elevation adjustment, first, the push rod drives the docking ball head on the adjusting pipe to rotate along the flange type ball head seat. During the rotation, due to the meshing of the first gear and the second gear, the first gear rotates. Then, the rotating first gear drives the third gear to rotate. The third gear drives the fourth gear to rotate through the central gear. However, since the fourth gear is fixed to the threaded type ball head seat, the threaded type ball head seat rotates along the docking ball head on the adjusting pipe, thereby adjusting the threaded type ball head seat. And the rotation direction of the threaded type ball head seat is the same as that of the adjusting pipe, enabling the present utility model to have the function of large-angle elevation and rotation adjustment, thus meeting different usage requirements.

[0018] The following describes the preferred embodiments of the present utility model with reference to the drawings. It should be understood that the preferred embodiments described herein are only used to illustrate and explain the present utility model and are not used to limit the present utility model.

[0019] Example: Figure 1 , Figure 2 , Figure 3 As shown, the utility model is a minimalist elevation and rotation structure for a fire monitor, comprising a flange type ball head seat 1, an adjusting tube 2 and a threaded ball head seat 3; both end portions of the adjusting tube 2 are provided with docking ball heads 4 docking with the flange type ball head seat 1 and the threaded ball head seat 3; an elevation and rotation mechanism is provided between the adjusting tube 2, the flange type ball head seat 1 and the threaded ball head seat 3.

[0020] Among them, the adjusting tube 2 is provided with an articulated block 5, an electric push rod 6 is installed between the flange ball head seat 1 and the articulated block 5, the adjusting tube 2 is provided with a first gear 7, the flange ball head seat 1 is provided with a second gear 8 meshing with the first gear 7; the second gear 8 is fixedly connected to the outer wall of the flange ball head seat 1. When performing pitch adjustment, the push rod first drives the docking ball head 4 on the adjusting tube 2 to rotate along the flange ball head seat, and during the rotation process, due to the meshing action of the first gear 7 and the second gear 8, the first gear 7 rotates, and the rotating first gear 7 drives the third gear 9 to rotate, and the third gear 9 drives the fourth gear 10 to rotate through the central gear, but because the fourth gear 10 is fixed to the threaded ball head seat 3, the threaded ball head seat 3 rotates along the docking ball head 4 on the adjusting tube 2, and then the threaded ball head seat 3 is adjusted, and the rotation direction of the threaded ball head seat 3 is consistent with the rotation direction of the adjusting tube 2, so that the utility model has the function of large-angle pitch rotation adjustment, thereby meeting different usage requirements.

[0021] Among them, the threaded ball head seat 3 is provided with a third gear 9, and the third gear 9 is fixedly connected to the outer wall of the threaded ball head seat 3; the adjusting tube 2 is provided with a fourth gear 10 which is transmission connected to the third gear 9; the fourth gear 10 is connected to the first gear 7 via a connecting shaft.

[0022] A retaining frame 11 is fixed on the regulating tube 2, and an intermediate gear 12 meshing with the third gear 9 and the fourth gear 10 is fixed on the retaining frame 11. Steering transmission is performed through the intermediate gear, while the manufacturing specifications of the third gear 9 and the fourth gear 10 are reduced.

[0023] The connection between the connecting shaft and the regulating tube 2 is connected via a sealing structure. The sealing mechanism is an existing sealing mechanism for sealing shafts, which belongs to an existing technical product, so its structure is not described here.

[0024] Among them, sealing rings 13 for sealing the connection part of the docking ball head 4 are provided on the flange ball head seat 1 and the threaded ball head seat 3 to seal the connection parts of the docking ball head with the flange ball head seat 1 and the threaded ball head seat 3, so as to ensure good sealing effect of the whole.

[0025] During operation, when performing pitching adjustment, first, the push rod drives the docking ball head 4 on the adjustment pipe 2 to rotate along the flange ball head seat. During the rotation, due to the meshing of the first gear 7 and the second gear 8, the first gear 7 rotates. The rotating first gear 7 drives the third gear 9 to rotate. The third gear 9 drives the fourth gear 10 to rotate through the central gear. However, since the fourth gear 10 is fixed to the threaded ball head seat 3, the threaded ball head seat 3 rotates along the docking ball head 4 on the adjustment pipe 2, thereby adjusting the threaded ball head seat 3. And the rotation direction of the threaded ball head seat 3 is the same as that of the adjustment pipe 2, so that the utility model has the function of large-angle pitching rotation adjustment, thus meeting different use requirements.

[0026] Finally, it should be noted that the above are only the preferred embodiments of the present utility model and are not used to limit the present utility model.
