DETAILED DESCRIPTION

[0023] The technical solution of the present utility model is further described below in conjunction with the accompanying drawings and embodiments.

[0024] like Figure 1-Figure 3As shown, the embodiment of the utility model proposes a controllable anti-overturning swivel ball joint, including a ball joint body 1, a mounting support 2, a protective cover body 3, a protective mounting assembly, and a quick positioning assembly: the protective cover body 3 is arranged in an annular hollow structure, a retention hole is arranged on the top of the protective cover body 3, the upper end of the ball joint body 1 is located at the retention hole, and the inner walls of the protective cover body 3 and the mounting support 2 are both provided with anti-slip patterns; the protective mounting assembly includes a mounting bolt 4 fixedly connected to the bottom of the protective cover body 3, a fixing nut is matched with the mounting bolt 4, a pressing plate 5 is threadedly connected to the mounting bolt 4, and the pressing plate 5 is attached to the outer wall of the protective cover body 3, a mounting threaded hole 6 is opened on the top of the mounting support 2, the mounting bolt 4 is matched with the mounting threaded hole 6, a plurality of fixing pins 12 are fixedly connected to the bottom of the pressing plate 5, a plurality of fixing holes 13 are opened at the bottom of the protective cover body 3 and the top of the mounting support 2, and the fixing pins 12 match the fixing holes 13;

[0025] The mounting bolt 4 can fix the protective cover body 3 and the mounting support 2 by being connected to the mounting threaded hole 6 on the mounting support 2. When the mounting bolt 4 is rotated, it can also rotate relative to the pressure plate 5 thread, so that the pressure plate 5 and the fixing pin 12 at the bottom thereof move downward, and then the protective cover body 3 and the mounting support 2 are further fixed by the fixing pin 12 being plugged in and corresponding with the fixing holes 13 on the protective cover body 3 and the mounting support 2 in turn. Therefore, the ball joint body 1 can be fully protected by the protective cover body 3 and the mounting support 2, and the position displacement and tilting of the ball joint body 1 can be avoided, thereby ensuring the stability of the ball joint device.

[0026] like Figure 1-Figure 3 As shown, the quick positioning component includes a plurality of positioning sockets 7 opened at the bottom of the protective cover body 3 and the top of the mounting support 2, a sleeve 8 is fixedly connected to the bottom of the protective cover body 3, a sliding plate 9 is slidably connected inside the sleeve 8, a pull rod 10 and a positioning guide rod 11 are fixedly connected to the top and bottom of the sliding plate 9 respectively, the positioning guide rod 11 matches the positioning socket 7, the upper end of the pull rod 10 passes through the top of the sleeve 8 and is fixedly connected to a top plate 14, a compression spring 15 is sleeved on the outer wall of the pull rod 10 located inside the sleeve 8, the upper and lower ends of the compression spring 15 are fixedly connected to the sleeve 8 and the sliding plate 9 respectively, an adjusting ring 16 is slidably connected to the outer wall of the protective cover body 3, a paddle 17 is arranged on the adjusting ring 16, and the paddle 17 is fixedly connected to the top plate 14 through a connecting rod, when it is necessary to disassemble the protective cover body 3, the ball joint body 1 and the mounting support 2, the positioning guide rod 11 can be driven to move upward by prying the paddle 17 upward to release the positioning fixation of the protective cover body 3 and the mounting support 2;

[0027] By rotating the protective cover body 3, the positioning guide rod 11 in the sleeve 8 can be driven to rotate synchronously, and the elastic force of the compression spring 15 can be used to push the sliding plate 9 and the positioning guide rod 11 to move downward elastically. When the positioning guide rod 11 corresponds to the positioning socket 7 on the mounting support 2, the protective cover body 3 and the mounting support 2 can be directly installed and fixed by the mounting bolts 4, thereby realizing the overall rapid installation of the protective cover body 3, the ball joint body 1 and the mounting support 2, thereby improving the installation or disassembly efficiency of the ball joint device.

[0028] The detailed working process of the utility model is as follows:

[0029] 1. When the ball joint device is in use, the protective cover body 3 is mounted on the ball joint body 1, and the mounting bolts 4 on the protective cover body 3 are aligned with the mounting threaded holes 6 on the mounting support 2, the mounting bolts 4 are rotated and the fixing nuts are fixed, so that the mounting bolts 4 are connected to the mounting threaded holes 6 on the mounting support 2 to fix the protective cover body 3 and the mounting support 2. In this process, the mounting bolts 4 are also threadedly rotated relative to the pressing plate 5, so that the pressing plate 5 and the fixing pin 12 at the bottom thereof move downward, and then the fixing pin 12 is sequentially connected with the protective cover body 3 and the fixing holes 13 on the mounting support 2 to further fix the protective cover body 3 and the mounting support 2, so that the ball joint body 1 can be fully protected by the protective cover body 3 and the mounting support 2, so as to avoid the position deviation and tilting of the ball joint body 1, and ensure the stability of the ball joint device;

[0030] 2. During the initial installation and positioning process of the protective cover body 3 and the mounting support 2, the mounting bolt 4 is not precisely aligned with the mounting threaded hole 6, and the lower end of the positioning guide rod 11 is in contact with the top of the mounting support 2. By rotating the protective cover body 3, the positioning guide rod 11 in the sleeve 8 can be driven to rotate synchronously, and the elastic force of the compression spring 15 is used to push the sliding plate 9 and the positioning guide rod 11 to move downward elastically. When the positioning guide rod 11 corresponds to the positioning socket 7 on the mounting support 2, the protective cover body 3 and the mounting support 2 can be directly installed and fixed by the mounting bolt 4, thereby realizing the overall rapid installation of the protective cover body 3, the ball joint body 1 and the mounting support 2, thereby improving the installation or disassembly efficiency of the ball joint device.
