It should be understood that the specific embodiments described here are part of the embodiments of the utility model, not all of the embodiments, and are only used to explain the embodiments of the utility model, and are not used to limit the embodiments of the utility model. All other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.

[0021] Embodiment 1

[0022] See also Figure 1-Figure 5 The utility model provides a technical solution: a PIN structure with increased durability, including a column 1, the column 1 is made of PEEK material, a thread groove 2 is opened inside the column 1, the internal thread of the thread groove 2 is connected with a stud 3, so that the stud 3 can be connected to the column 1, the top of the stud 3 is fixedly connected with a connecting rod 4, the top of the connecting rod 4 is fixedly connected with a screw head 5, the stud 3, the connecting rod 4 and the screw head 5 together constitute a bolt, which is made of 316 stainless steel, and when replacing accessories, it will not react with the medicine, so that the use stability is higher.

[0023] When the column 1 needs to be installed, the column 1 is placed at a specified position on the mounting seat, and the stud 3 is passed through the mounting seat, so that the stud 3 can enter the interior of the thread groove 2. At this time, the screw head 5 is rotated to drive the connecting rod 4 to rotate, and the connecting rod 4 can drive the stud 3 to rotate inside the thread groove 2, so that the column 1 can be connected to the mounting seat through the stud 3, the connecting rod 4, and the screw head 5. This not only increases the PIN fixing force area and reduces the damage rate, thereby greatly reducing the replacement frequency of the column 1 and making the equipment run more stably, but also saves materials and reduces the price of accessories, making it more economical to use.

[0024] Embodiment 2

[0025] On the basis of the first embodiment, in order to achieve a more stable installation of the stud 3 and the thread groove 2, a slot 6 is provided on the outer side of the connecting rod 4, and a gasket 7 is clamped inside the slot 6, so that the gasket 7 can be conveniently connected to or separated from the slot 6, and the bottom end of the gasket 7 fits with the top end of the column 1, thereby preventing the top end of the column 1 from directly contacting the mounting seat, so that the column 1 will not be worn by friction from the mounting seat, and the inner side of the gasket 7 is slidably connected to the outside of the stud 3, so that the gasket 7 can slide upward on the outside of the stud 3, and then can be connected to the inner side of the connecting rod 4. The bottom end of the gasket 7 is fixedly connected with a conical block 8, the outer side of the conical block 8 is conically designed, and the outer side of the conical block 8 fits with the inner upper side of the thread groove 2, so that the stud 3 will not be easily loosened, and the bottom end of the conical block 8 is fixedly connected with a connecting block 9, and the outer side of the connecting block 9 is fixedly connected with a plurality of sealing rings 10, and the outer side of the sealing ring 10 fits with the inner upper side of the stud 3, so that the stud 3 will not be easily loosened. The gasket 7, the conical block 8, the connecting block 9 and the sealing ring 10 are all made of rubber material, so that they can be deformed.

[0026] When in use, by sleeved gasket 7 on the outside of stud 3, the inner side of gasket 7 is squeezed and deformed, and then gasket 7 is slid upward, so that gasket 7 can slide into the inside of slot 6, so that gasket 7 can make a reset movement, and then can be engaged with the inside of slot 6. At this time, by screwing stud 3 into the inside of thread groove 2, gasket 7 is fit with the top of column 1, and then conical block 8, connecting block 9 and sealing ring 10 are able to enter the inside of thread groove 2. In this process, thread groove 2 can squeeze conical block 8 and sealing ring 10 to produce deformation, and then when it makes a reset movement, conical block 8 and sealing ring 10 can fit tightly with the inside of thread groove 2, so that the connection between thread groove 2 and stud 3 is more stable, and stud 3 will not loosen easily.

[0027] Embodiment 3

[0028] On the basis of the second embodiment, in order to achieve that the contact surface between the column 1 and the mounting seat does not produce wear, a plurality of slots 14 are provided inside the top of the column 1, and the plurality of slots 14 are distributed in a ring shape, so that the force on the column 1 is more uniform, and an insert block 13 is inserted inside the slot 14, and both sides of the upper side of the outer side of the insert block 13 are conical in design, so that the insert block 13 can easily enter the interior of the placement block 12, and the insert block 13 matches the slot 14, and the top of the insert block 13 is fixedly connected to the placement block 12, and the outer side of the placement block 12 is slidably connected to the slot 14. Internally, the slot 14 limits the placement block 12, so that the placement block 12 will not shift when moving. The top of the placement block 12 is fixedly connected with an extension piece 11, and the extension piece 11 is made of rubber material so that it can be deformed. The inner side of the extension piece 11 is fixedly connected to the outer periphery of the gasket 7. The extension piece 11 is used in conjunction with the gasket 7 so that the surface of the column 1 is completely covered, thereby preventing the contact surface between the top of the column 1 and the mounting seat from being worn. The extension piece 11 and the plug-in block 13 are both made of rubber material so that they can be deformed.

[0029] When the gasket 7 fits with the top of the column 1, the plug 13 is pushed by the mounting seat and can slide into the interior of the slot 14. In this process, the slot 14 can squeeze the plug 13 to deform, and then when the bottom end of the extension piece 11 fits with the top of the column 1, the plug 13 can perform a reset movement, so that the plug 13 can be filled in the interior of the slot 14, so that the plug 13 will not easily detach from the interior of the slot 14 when there is no upward force, so that the extension piece 11 is installed more stably, thereby making the durability of the structure higher.

[0030] When the screw head 5 is rotated, the screw head 5 drives the connecting rod 4 to rotate, and the connecting rod 4 drives the stud 3 to rotate in the thread groove 2, so that the column 1 can be connected with the mounting seat through the stud 3, the connecting rod 4 and the screw head 5, so that the conical block 8, the connecting block 9 and the sealing ring 10 can enter the interior of the thread groove 2. In this process, the thread groove 2 can squeeze the conical block 8 and the sealing ring 10 to deform, and when it performs the reset movement, the conical block 8 and the sealing ring 10 can be locked in the thread groove 2. The shaped block 8 and the sealing ring 10 can fit tightly with the inside of the thread groove 2, so that the connection between the thread groove 2 and the stud 3 is more stable, and the stud 3 will not be easily loosened. At this time, the plug block 13 is pushed by the mounting seat, so that it can slide into the inside of the slot 14. In this process, the slot 14 can squeeze the plug block 13 to produce deformation, and then when the bottom end of the extension piece 11 fits with the top of the column 1, the plug block 13 can be reset, so that the plug block 13 can be filled in the inside of the slot 14, so that when the plug block 13 is not subjected to an upward force, the plug block 13 will not easily detach from the inside of the slot 14, and the extension piece 11 can be installed more stably, so that the durability of the structure is higher, which can not only increase the PIN fixed force area and reduce the damage rate, thereby greatly reducing the replacement frequency of the column 1, making the equipment operation more stable, but also save materials, reduce the price of accessories, and make it more economical to use.
