Description

Technical Field

[0001] The utility model belongs to the field of photographic accessories, and in particular relates to a splicable catheter. Background Art

[0002] The catheters currently available on the market are long and short, but cannot be extended or shortened according to user needs. If the user wants a longer or shorter catheter, the longer or shorter catheter can only be replaced. In order to solve this problem, the present practical technical solution came into being. Summary of the invention

[0003] In order to solve the problems in the background technology, the utility model provides a splicable conduit, including an upper adapter cover, a conduit, a long bolt and a lower adapter cover, characterized in that: the conduit is hollow, and the two ends are respectively inserted into the upper adapter cover and the lower adapter cover; the outer end covers of the upper adapter cover and the lower adapter cover are limited to the outside of the conduit; the middle part of the upper adapter cover is through, and there are threaded holes 1 and through holes from top to bottom, and the aperture of the threaded hole 1 is larger than that of the through hole; the middle part of the lower adapter cover is through, and there are threaded holes 2 and threaded holes 3 from top to bottom; the through hole and threaded hole 2 are adapted to long bolts; the long bolt passes through threaded hole 1, through hole and conduit in sequence, and is then connected to threaded hole 2, and the head of the long screw is limited to the lower half of threaded hole 1. Preferably, the conduit is made of carbon fiber.

[0004] From the above technical solutions, it can be seen that the embodiments of the utility model have the following positive effects:

[0005] The two ends of the conduit are inserted into the adapter cover, and the long bolts are used to reinforce the connection between the conduit and the adapter cover. The adapter cover can be spliced ​​with other conduits to extend the length. If the user wants a longer or shorter conduit, he can splice or disassemble other conduits through the adapter cover to extend or shorten the conduit. BRIEF DESCRIPTION OF THE DRAWINGS

DETAILED DESCRIPTION

[0012] The present invention is further explained below in conjunction with the accompanying drawings, but the protection scope of the present invention is not limited thereto.

[0013] See also Figure 1-3 The utility model provides a splicable conduit, comprising an upper adapter cover 1, a conduit 2, a long bolt 3 and a lower adapter cover 4, wherein the conduit 2 is hollow, and the two ends are respectively inserted into the upper adapter cover 1 and the lower adapter cover 4, wherein the extended inner wall 1-2 of the upper adapter cover and the extended inner wall 4-2 of the lower adapter cover are respectively embedded in the conduit; the outer end covers of the upper adapter cover and the lower adapter cover are limited to the outside of the conduit; the middle part of the upper adapter cover is through, and from top to bottom are threaded holes 1-3 and through holes 1-1, and the aperture of the threaded hole 1-3 is larger than that of the through hole 1 -1; the middle part of the lower adapter cover is through, and from top to bottom are threaded hole two 4-1 and threaded hole three 4-3, the aperture of threaded hole three 4-3 is not less than that of threaded hole two 4-1; the through hole 1-1 and threaded hole two 4-1 are adapted to long screw 3; the long bolt 3 passes through threaded hole one 1-3, through hole 1-1 and conduit 2 in sequence, and is then connected to threaded hole two 4-1, and the head of the long screw is limited to the lower half of threaded hole one; the upper half of threaded hole one and threaded hole three can be externally connected with screws to splice other conduits.

[0014] The conduit can be made of carbon fiber, metal, etc.

[0015] See also Figure 4-5 In the application scenario of this technical solution, either end of the splicable conduit is connected to the adapter component. The adapter component with a screw is connected to the threaded hole 1 of the upper adapter cover or the threaded hole 3 of the lower adapter cover. A threaded hole is reserved at the other end of the adapter component for connecting another splicable conduit. In this way, the length of the conduit is extended. Users can extend or shorten the conduit according to their needs.

[0016] It is obvious to those skilled in the art that the present invention is not limited to the details of the exemplary embodiments described above, and that the present invention can be implemented in other specific forms without departing from the spirit or basic features of the present invention.
