[0024] In order to better understand the purpose, structure and function of the present invention, the present invention is described in further detail below with reference to the accompanying drawings.

[0025] like Figures 1-8 As shown, the conveniently detachable inner marching fixing device of the present invention includes: a tailstock assembly 1, an insert shaft assembly 2, a rod 3, a turret mounting support 4, a breech support 5, a cover 6, a cap 7, a spring 8, an insert shaft 9, a baffle 10, a shaft 11, a compression spring 12, a pin shaft II 13, a turret support 14, a pad 15, and a cotter pin 16.

[0026] like Figure 2 、 4 As shown, the breech support 5 is fixed with a cap 7 by means of threads and spot riveted to prevent loosening. The cover 6 and spring 8 are pre-installed in the hole of the breech support 5, and the cap 7 is used to adjust the limit, forming the breech support assembly 1;

[0027] like Figure 3 、 5 As shown, install the baffle 10 in the slot of the plug shaft 9, fix it with the shaft 11, and weld the end of the shaft 11 to prevent it from loosening. Install the compression spring 12 on the end face of the shaft 11 to form the plug shaft assembly 2;

[0028] like Figure 7 As shown, one end of the round hole of the rod 3 is connected to the tailstock assembly 1 using the plug-in shaft assembly 2, and one end of the hook is hung on the turret mounting support 4;

[0029] like Figure 6 As shown, insert the pin shaft II 13 into the hole of the turret support 14, and put the pad 15 on the other end of the pin shaft II 13, install the cotter pin 16 to limit the position, and form the turret mounting support 4;

[0030] The present invention is assembled as Figure 8As shown, the connection relationship between the above components is as follows: the tailstock assembly 1 is inserted into the breech slot and can be fixed to the breech by rotating it 90°; the turret mounting bracket 4 is installed at a suitable position on the turret using the threaded hole of the turret bracket 14; one end of the rod 3 hook is hung on the pin shaft II 13 of the turret mounting bracket 4, and one end of the circular hole is connected to the tailstock assembly 1 by the plug-in shaft assembly 2; when installing the rod 3 and the plug-in shaft assembly 2, the baffle 10 in the plug-in shaft assembly 2 is rotated onto the axis of the plug-in shaft 9, and inserted into the circular holes of the tailstock assembly 1 and the rod 3, the plug-in shaft assembly 2 is pressed to compress the compression spring 12, and the baffle 10 is rotated 90° so that the long end fits against the end face of the breech bracket 5, thereby locking the marching fixture device.

[0031] The specific working process of this embodiment is as follows:

[0032] When the combat state is converted to the marching state, align the tailstock small mounting slot with the breech slot, insert it into it, press the breech support and rotate it 90° to fix the tailstock small mounting on the breech; hang the rod on the turret mounting support; rotate the other end of the rod to coincide the round hole with the round hole of the tailstock small mounting, rotate the baffle in the plug-in shaft assembly onto the plug-in shaft axis, insert it into the round holes of the tailstock small mounting and the rod, press the plug-in shaft assembly to compress the compression spring, rotate the baffle 90° to make the long end fit against the end face of the breech support, thereby locking the marching fixture device.

[0033] When the marching state is converted to the combat state, press the plug-in shaft assembly to compress the compression spring, rotate the baffle 90° so that the baffle is on the plug-in shaft axis, and pull out the plug-in shaft assembly; rotate the rod to release the hook end of the rod from the turret mounting bracket, and remove the rod; press the breech bracket and rotate it 90°, align the tailstock small mounting slot with the breech slot, and remove the tailstock small mounting, thereby completing the release of the marching fixture device.

[0034] The present invention solves the problem of locking the elevation of the lifting part of a self-propelled artillery during marching, thereby preventing the elevation mechanism and the gear arc from being damaged by continuous vibration and impact during marching. At the same time, the release and locking actions during marching-combat conversion are rapid, shortening the conversion time. The time personnel spend outside the tower is reduced, making it convenient for personnel to release and lock the marching fixture inside the tower, thereby improving the safety of equipment combat.

[0035] Although the embodiments of the present invention are described in conjunction with the accompanying drawings, those skilled in the art may make several modifications and improvements without departing from the principles of the present invention, and these modifications and improvements should also be considered to fall within the scope of protection of the present invention.
