Description

Technical Field

[0001] The utility model relates to the technical field of snake bone connection structures, in particular to a snake bone connection structure. Background Art

[0002] At present, electronic endoscopes are commonly used medical devices in the prior art, which usually include a bending part. This bending part generally realizes the bending function through a snake bone assembly that can bend in four directions. By operating the angle control knob of the operating part, the internal chain and steel wire of the endoscope are driven to drive the snake bone of the bending part to bend up and down and left and right.

[0003] In the Chinese utility model patent with the publication number CN217310233U, an endoscope snake bone connection structure and an endoscope are disclosed. In the above prior art, although the rivet cap does not occupy the radial space of the connection joint ring, thereby increasing the utilization rate of the internal space of the snake bone and reducing the outer diameter of the snake bone, the snake bone connection structure needs to be adjusted according to the usage scenario during use. Some adjustments will lengthen or shorten the snake bone connection structure. When using rivet caps to connect multiple snake bone units, although it does not affect the bending of the snake bone connection structure, it will be very troublesome to disassemble and separate the snake bone connection structure. Therefore, it is necessary to design a snake bone connection structure that can quickly and conveniently disassemble or assemble the snake bone connection structure. Summary of the Utility Model

[0004] To solve the technical problem that using rivets to connect snake bone connectors will cause trouble and affect efficiency when the snake bone needs to be disassembled, the utility model provides a snake bone connection structure.

[0005] The utility model is realized by the following technical solutions: A snake bone connection structure includes a plurality of snake bone units. On one side of each snake bone unit, two disc-shaped first connection plates are fixedly installed. On the other side of each snake bone unit, two disc-shaped second connection plates are fixedly installed. The two first connection plates are adapted to the adjacent second connection plates. On one side of each first connection plate, there is a connection component for rotatably matching the first connection plate with the adjacent second connection plate. On one side of each second connection plate, there is a removal component for quickly removing the adjacent connection component from the adjacent first connection plate and second connection plate. The connection component includes a connection column arranged on one side of the first connection plate and a limit plate fixedly installed at one end of the connection column. One end of the connection column penetrates through the adjacent first connection plate and the adjacent second connection plate, and the first connection plate is rotatably matched with the second connection plate through the connection column.

[0006] Through the above technical solutions, when the snake bone connection structure needs to be disassembled, the removal component can be used to quickly push the connection component, so that two snake bone units can be separated.

[0007] As a further improvement of the above solution, a contraction spring is sleeved on the connecting column. One end of the contraction spring is fixedly installed with the limiting plate, and the other end is fixedly installed with the adjacent first connecting plate.

[0008] Through the above technical solution, the contraction spring will always pull the limiting plate to prevent the connecting column from automatically disengaging from the first connecting plate and the second connecting plate.

[0009] As a further improvement of the above solution, a first protective cover for protecting the adjacent connecting components is provided on one side of each of the first connecting plates.

[0010] Through the above technical solution, the first protective cover can prevent objects from affecting the contraction spring during use.

[0011] As a further improvement of the above solution, a storage groove is provided on one side of each of the second connecting plates. The removing component includes a pushing column arranged inside the storage groove, a pulling block rotatably installed on one side of the pushing column, and a pulling ring rotatably engaged with the pulling block.

[0012] Through the above technical solution, by pulling out the pushing column and using the pushing column to push the connecting column, the first connecting plate and the second connecting plate can be separated.

[0013] As a further improvement of the above solution, an annular insertion groove is provided on one side of each of the second connecting plates. A second protective cover is provided on each of the insertion grooves. A sliding groove is provided on one side of the inner wall of each of the insertion grooves. An insertion groove penetrating the adjacent second connecting plate is provided on one side of each of the sliding grooves. A limiting block is fixedly installed on one side of the inner wall of each of the second protective covers.

[0014] Through the above technical solution, inserting the second protective cover into the insertion groove can prevent parts such as the pulling block and the pulling ring from hurting people.

[0015] As a further improvement of the above solution, a first indicating block is fixedly installed on one side of each of the second connecting plates, and a second indicating block is provided on one side of each of the second protective covers.

[0016] Through the above technical solution, the protective cover can be removed after the second indicating block is aligned with the first indicating block.

[0017] Compared with the prior art, the beneficial effects of the present utility model are as follows:

[0018] By providing a connecting component and a removing component, when it is necessary to disassemble the snake bone connecting structure, the second protective cover is removed, and the removing component is used to squeeze and push the connecting component, so that the corresponding first connecting plate and the second connecting plate can be separated, thereby disassembling the snake bone connecting structure. This setting can not only increase or decrease the snake bone connecting structure, but also quickly disassemble the snake bone connecting structure. BRIEF DESCRIPTION OF THE DRAWINGS

[0025] Next, in combination with the accompanying drawings and specific embodiments, the present utility model will be further described. It should be noted that, on the premise of no conflict, the following-described embodiments or technical features can be arbitrarily combined to form new embodiments.

[0026] Please refer to Figures 1 - 4, A snake bone connection structure of this embodiment includes a plurality of snake bone units 1. On one side of each snake bone unit 1, two disk-shaped first connecting plates 2 are fixedly installed. On the other side of each snake bone unit 1, two disk-shaped second connecting plates 3 are fixedly installed. The two first connecting plates 2 are adapted to the adjacent second connecting plates 3. On one side of each first connecting plate 2, there is a connecting component for the first connecting plate 2 to rotate and cooperate with the adjacent second connecting plate 3. On one side of each second connecting plate 3, there is a removing component for quickly removing the adjacent connecting component from the adjacent first connecting plate 2 and second connecting plate 3. The connecting component includes a connecting column 401 provided on one side of the first connecting plate 2 and a limiting plate 402 fixedly installed at one end of the connecting column 401. One end of the connecting column 401 penetrates through the adjacent first connecting plate 2 and the adjacent second connecting plate 3. The first connecting plate 2 is rotationally matched with the second connecting plate 3 through the connecting column 401. A compression spring 6 is sleeved on the connecting column 401. One end of the compression spring 6 is fixedly installed with the limiting plate 402, and the other end is fixedly installed with the adjacent first connecting plate 2. On one side of each first connecting plate 2, there is a first protective cover 7 for protecting the adjacent connecting component. When the snake bone connection structure needs to be disassembled, the removing component can be used to quickly push the connecting component, so that the two snake bone units 1 are separated. The compression spring 6 will always pull the limiting plate 402 to prevent the connecting column 401 from automatically detaching from the first connecting plate 2 and the second connecting plate 3.

[0027] Combined with Figures 1 - 4 , On one side of each second connecting plate 3, a storage groove is opened. The removing component includes a pushing column 501 arranged inside the storage groove, a pulling block 502 rotatably installed on one side of the pushing column 501, and a pulling ring 503 rotatably matched with the pulling block 502. On one side of each second connecting plate 3, an annular insertion groove is opened. On each insertion groove, there is a second protective cover 8. On one side of the inner wall of each insertion groove, a sliding groove is opened. On one side of each sliding groove, an insertion groove penetrating through the adjacent second connecting plate 3 is opened. On one side of the inner wall of each second protective cover 8, a limiting block 9 is fixedly installed. On one side of each second connecting plate 3, a first indicating block 10 is fixedly installed. On one side of each second protective cover 8, there is a second indicating block 11. After the second indicating block 11 and the first indicating block 10 are aligned, the protective cover 8 can be removed. Pull out the pushing column 501 and use the pushing column 501 to push the connecting column 401, then the first connecting plate 2 and the second connecting plate 3 can be separated.

[0028] In the embodiment of the present application, the implementation principle of a snake bone connection structure is as follows: When it is necessary to disassemble the snake bone connection structure, rotate the second protective cover 8 so that the limiting block 9 can be taken out from the insertion groove, and then the second protective cover 8 can be removed. Then, use the pull ring 503 to take out the push column 501 from the storage groove, and then push against the connection column 401. In this way, the connection column 401 will be pushed backward, so as to be separated from the second connecting plate 3. After both sides are processed in this way, the two snake bone units 1 can be separated. When adding and installing other snake bone units 1, squeeze the connection column 401 and then place another snake bone unit 1 in place. The connection column 401 can be pushed by the contraction spring 6, so that the two snake bone units 1 can be rotationally matched. Such a setting can not only increase or decrease the snake bone connection structure, but also quickly disassemble the snake bone connection structure.

[0029] The above-mentioned implementation manners are only the preferred implementation manners of the present invention, and cannot be used to limit the scope of protection of the present invention. Any non-substantial changes and substitutions made by those skilled in the art on the basis of the present invention belong to the scope of protection required by the present invention.
