[0023] A buffer type precision steel tube, comprising a steel tube body 1, an outer cover shell 2, a buffer 3 and an assembly part 4. The outer cover shells 2 are symmetrically arranged on the outside of the front and rear ends of the steel tube body 1. The buffer 3 is arranged between the outside of the steel tube body 1 and the inside of the outer cover shell 2. The assembly part 4 is arranged between the outer cover shells 2 at the front and rear ends. The buffer 3 includes a small kit 31, a large kit 32 and a flexible rubber plate 33. The large kit 32 is arranged at one end of the small kit 31 away from the steel tube body 1. The flexible rubber plate 33 is fixedly arranged between the small kit 31 and the large kit 32. The assembly part 4 includes a small clamp 41, a first silicone sheet 42, a large clamp 43, a second silicone sheet 44, a column 45, a threaded rod 46 and a hexagonal nut 47. The first silicone sheet 42 is fixedly provided at one end of the small clamp 41 close to the outer cover shell 2, the second silicone sheet 44 is fixedly provided at one end of the large clamp 43 close to the outer cover shell 2, the column 45 is fixedly provided at one end of the small clamp 41 close to the large clamp 43, and the threaded rod 46 is fixedly provided at one end of the column 45 away from the small clamp 41. The threaded rod 46 is threadedly assembled with the hexagonal nut 47.

[0024] The semicircular grooves symmetrically distributed on the outside of the steel pipe body 1 are in contact with the small kit 31, and the semicircular grooves symmetrically distributed on the inside of the outer cover shell 2 are in contact with the large kit 32. Through the above arrangement, the assembly limiting function of the buffer 3 and the steel pipe body 1 and the outer cover shell 2 is improved.

[0025] The buffer members 3 are symmetrically distributed between the steel pipe body 1 and the outer cover shell 2 distributed at the front and rear ends. Through the above arrangement, the symmetrically distributed buffer members 3 provide buffering protection against forces in multiple directions outside the outer cover shell 2.

[0026] When the assembly part 4 assembles the outer cover shell 2 set at the front and rear ends, the first silicone sheet 42 is in contact with and fits against the inner side of the outer cover shell 2, the second silicone sheet 44 is in contact with and fits against the outer side of the outer cover shell 2, and the column rod 45 is slidably inserted into the inner hole opened by the second silicone sheet 44 and the inner hole opened by the large clamp 43. Through the above-mentioned setting, the installation and positioning of the internal components of the assembly part 4 play a role in pre-assembly and placement of the outer cover shell 2 set at the front and rear ends.

[0027] The assembly parts 4 are symmetrically distributed on the left and right sides of the steel pipe body 1, and the column rods 45 are in contact with the outer cover shells 2 set at the front and rear ends. Through the above arrangement, the assembly parts 4 play an assembly and combination role for the outer cover shells 2 set at the front and rear ends.

[0028] Working process: The utility model provides a buffer-type precision steel pipe. The main structure for protecting the steel pipe body 1 with a shell is easy to assemble. The steel pipe body 1 can be buffered and protected by the buffer part 3 arranged between the steel pipe body 1 and the outer cover shell 2.

[0029] First, the outer cover shell 2 set at the front and rear ends is assembled by the assembly parts 4, wherein the small clamp 41, the first silicone sheet 42, the column 45 and the threaded rod 46 are integrated internal accessories, and the large clamp 43 and the second silicone sheet 44 are integrated external accessories. Figure 4 、 Figure 5 As shown, the column rod 45 is inserted and placed between the outer cover shells 2 set at the front and rear ends, so that the first silicone sheet 42 is in contact with the inner side of the outer cover shell 2, and the second silicone sheet 44 is in contact with the outer side of the outer cover shell 2. The column rod 45 is slidably inserted and placed with the inner hole opened by the second silicone sheet 44 and the inner hole opened by the large clamp 43, and then the hexagonal nut 47 is threadedly assembled with the threaded rod 46 until the hexagonal nut 47 is in contact with the outer side of the large clamp 43, completing the combined assembly of the outer cover shell 2.

[0030] Then the buffer 3 is assembled and inserted vertically between the outer side of the steel pipe body 1 and the inner side of the outer cover shell 2 until the top of the small kit 31 is flush with the top of the steel pipe body 1. At this time, the semicircular grooves symmetrically distributed on the outer side of the steel pipe body 1 are in contact with the small kit 31, and the semicircular grooves symmetrically distributed on the inner side of the outer cover shell 2 are in contact with the large kit 32. The assembly protection of the steel pipe body 1 is completed through the outer cover shell 2, the buffer 3 and the assembly parts 4.

[0031] When the outer cover shell 2 is subjected to external impact, since the buffer parts 3 are symmetrically distributed between the steel pipe body 1 and the outer cover shell 2, buffering protection can be provided in multiple directions. The flexible rubber plate 33 is a curved plate formed by injection molding of rubber resin liquid. The stress deformation of the flexible rubber plate 33 bent inside the buffer part 3 plays a role of flexible buffering against external impact, which can effectively buffer the steel pipe body 1.

[0032] Although the embodiments of the present invention have been shown and described, it will be understood by those skilled in the art that various changes, modifications, substitutions and variations may be made to these embodiments without departing from the principles and spirit of the present invention, and the scope of the present invention is defined by the appended claims and their equivalents.
