[0022] The present invention is further described in detail below in conjunction with the accompanying drawings. These drawings are simplified schematic diagrams, which only illustrate the basic structure of the present invention in a schematic manner. The direction of this specific implementation is to Figure 1 Direction is standard.

[0023] like Figures 1 to 4As shown, a direction-adjustable anti-dismantling column comprises a mounting column shell 1 and a mounting column body 2, the mounting column shell 1 is provided with an inner cavity 11 for accommodating the mounting column body 2, the mounting column shell 1 can be sleeved on the mounting column body 2, the mounting column body 2 is provided with an anti-slip ring 3 and a limiting groove 21 matched with the anti-slip ring 3, the anti-slip ring 3 is provided with a notch, and the inner side wall of the mounting column shell 1 is provided with a clamping groove 12 matched with the anti-slip ring 3, squeezing the anti-slip ring 3 can reduce the diameter of the anti-slip ring 3 so as to embed the mounting column body 2 into the inner cavity 11 of the mounting column shell 1, and when the mounting column body 2 is located in the inner cavity 11 of the mounting column shell 1, the anti-slip ring 3 can be clamped with the clamping groove 12 and the limiting groove 21 at the same time to prevent the mounting column body 2 from slipping out of the mounting column shell 1.

[0024] At least two disassembly structures 4 for squeezing the anti-slip ring 3 so that the mounting column body 2 can slip out of the mounting column housing 1 are provided on the mounting column housing 1. The disassembly structure 4 includes a squeezing screw 41 and a disassembly hole 42 provided on the mounting column housing 1. The disassembly hole 42 is provided corresponding to the card slot 12. The squeezing screw 41 is threadedly connected with the disassembly hole 42. The squeezing screw 41 can extend into the inner cavity 11 of the mounting column housing 1 from the disassembly hole 42 to squeeze the anti-slip ring 3 so that the mounting column body 2 can slip out of the mounting column housing 1.

[0025] The disassembly structures 4 of the present invention are evenly arranged along the circumference of the mounting column body 2. Since the anti-slip ring 3 is provided with a notch, there is an extrusion screw 41 that cannot hit the anti-slip ring 3 when it is extended into the inner cavity 11. Therefore, during disassembly, the position of the extrusion screw 41 must be found first. The specific operation is to screw all four extrusion screws 41 into the disassembly holes 42 first. Obviously, there is a relatively deep extrusion screw 41 that is not against the anti-slip ring 3. At this time, the extrusion screw 41 can be withdrawn to a certain position or completely withdrawn for disassembly.

[0026] At least two orientation structures 5 are also provided on the mounting column housing 1 for preventing the mounting column body 2 from rotating relative to the mounting column housing 1. The orientation structure 5 includes an orientation screw 51 and an orientation hole 52 provided on the mounting column housing 1. The orientation screw 51 is threadedly connected to the orientation hole 52. The orientation screw 51 can extend from the orientation hole 52 into the inner cavity 11 of the mounting column housing 1 to abut against the mounting column body 2 to prevent the mounting column body 2 from rotating.

[0027] The orientation structures 5 are evenly distributed along the circumference of the mounting column body 2 , and may be provided with 3, 4 or more. When disassembling the mounting column body 2 , the orientation screws 51 need to be screwed out of the orientation holes 52 first, and then the mounting column body 2 is disassembled through the disassembly structures 4 .

[0028] The end of the extrusion screw 41 that abuts against the anti-slip ring 3 is provided with a marble 43 for reducing friction. In this way, it is more labor-saving when the mounting column body 2 is pulled out of the inner cavity 11.

[0029] A first stud 13 for installation is also provided at one end of the mounting column housing 1, and a first anti-disassembly structure 6 for preventing disassembly is provided on the first stud 13. The first anti-disassembly structure 6 includes a first tightening screw 61, a compression spring 62 and a spring pressure block 63. One end of the compression spring 62 abuts against the first stud 13, and the other end of the compression spring 62 abuts against the spring pressure block 63. A first through hole 14 for accommodating the first tightening screw 61 is provided on the first stud 13. The first through hole 14 is connected to the inner cavity 11, and the first tightening screw 61 enters the first through hole 14 from the inner cavity 11 and passes through the compression spring 62 and is threadedly connected to the spring pressure block 63.

[0030] like Figure 4 As shown, the compression spring 62 is in a tower shape, and the diameter of the compression spring 62 gradually increases along its length direction. Compressing the compression spring 62 can increase the maximum diameter of the compression spring 62. The rotation direction of the coil of the compression spring 62 is opposite to the thread direction of the first stud 13. The rotation direction of the coil of the compression spring 62 is also opposite to the thread direction of the first tensioning screw 61.

[0031] When the first stud 13 of the mounting column housing 1 is threadedly connected to the bottom of the choke housing, since the first tightening screw 61 is threadedly connected to the spring pressure block 63, rotating the first tightening screw 61 can reduce the distance between the spring pressure block 63 and the first stud 13, so that the compression spring 62 can be compressed, and the maximum diameter of the compression spring 62 is increased to engage with the bottom internal thread of the choke housing, so that it cannot be removed by rotating the mounting column housing 1; to disassemble the mounting column housing 1, the mounting column body 2 must be removed first, and then the first tightening screw 61 in the first through hole 14 is rotated from the inner cavity 11 to increase the distance between the spring pressure block 63 and the first stud 13, so as to achieve the effect of loosening the compression spring 62, so that it returns to its original state and does not engage with the bottom internal thread of the choke housing, so that the mounting column housing 1 can be separated from the choke housing.

[0032] A second stud 22 for installation is provided at one end of the mounting column body 2, and a second anti-disassembly structure 7 for preventing disassembly is provided on the second stud 22. The second anti-disassembly structure 7 includes a second tightening screw 71 and a diagonal pull block 72. A first inclined surface 24 is provided on the second stud 22, and a second inclined surface 74 matching the first inclined surface 24 is provided on the diagonal pull block 72. The first inclined surface 24 abuts against the second inclined surface 74 to prevent the diagonal pull block 72 and the second stud 22 from rotating relative to each other. A second through hole 23 for accommodating the second tightening screw 71 is provided on the mounting column body 2, and the second tightening screw 71 can pass through the second through hole 23 and be threadedly connected with the diagonal pull block 72.

[0033] The outer diameter of the inclined tie block 72 is slightly smaller than the outer diameter of the second stud 22 .

[0034] The second stud 22 of the mounting column body 2 is generally threadedly connected to the mounting seat for mounting the choke. When the mounting column body 2 is installed, the inclined pull block 72 does not abut the second stud 22, and the second stud 22 can be screwed into the mounting seat for mounting the choke. After the mounting column body 2 is installed, the second tightening screw 71 is rotated from the second through hole 23 to make the second inclined surface 74 of the inclined pull block 72 abut against the first inclined surface 24 of the second stud 22, and the inclined pull block 72 abuts against the thread of the mounting seat for mounting the choke, so that the second stud 22 cannot be removed; when the mounting column body 2 is removed from the mounting seat, the mounting column body 2 must be removed from the mounting column housing 1, and then the second tightening screw 71 is rotated from the second through hole 23 to increase the distance between the inclined pull block 72 and the second stud 22, and the second inclined surface 74 does not abut against the first inclined surface 24, so that the mounting column body 2 can be removed from the mounting seat. A first anti-disassembly structure 6 for preventing disassembly may also be provided on the second stud 22 at one end of the mounting column body 2 .

[0035] The inner diameter of the first through hole 14 is smaller than the outer diameter of the nut of the first tightening screw 61 , and the inner diameter of the second through hole 23 is smaller than the outer diameter of the nut of the second tightening screw 71 .

[0036] The circumference of the anti-slip ring 3 is three times the length of its notch.

[0037] like Figure 5 As shown, one end of the mounting column housing 1 can also be provided with a second anti-disassembly structure 7, and the other end of the mounting column housing 1 is connected to the mounting column body 2. Some instruments can provide multi-screw flange installation, so the other end of the mounting column housing 1 can be installed by setting a flange. The screw heads used for installing the flange are non-universal screw heads. After the overall installation is completed, it is difficult to directly remove the screws on the flange. The tools used not only require a specific non-common wrench, but also the wrench must have a small 90-degree bend, which is generally difficult to achieve. This can also achieve an anti-disassembly effect, while simplifying the structure and reducing costs.

[0038] like Figure 6 As shown, both ends of the mounting column housing 1 can be mounted with flanges, which can also simplify the structure and reduce the cost.

[0039] The above description is only a preferred embodiment of the present invention and is not intended to limit the present invention. Any modifications, equivalent substitutions, improvements, etc. made within the spirit and principles of the present invention should be included in the scope of protection of the present invention.
