In general, hydraulic hoses are provided in heavy equipment such as a perforator or various devices to be used to move high pressure fluids such as air and hydraulics. The hydraulic hose uses a flexible high pressure hose made of a rubber material or the like in order to distribute fluid such as air, water, oil, and the like.

In order to connect these hydraulic hoses with various devices, various connection structures are used. Registration Utility Model Publication No. 20-0198059 discloses a structure for connecting a conventional hydraulic hose. Such a conventional hydraulic hose connection structure forms a locking jaw at the front end by forging a pipe-like material having a relatively small thickness in a hollow state, and forms a flat, straight rotation-preventing support surface portion on a rear outer circumferential surface thereof. A hose connector formed at the rear end of the face portion and formed with a crimp groove and a locking jaw, and a long indentation pipe formed at the rear end; A fastening nut having a locking jaw formed at a rear end in advance; At the rear end, it consists of a flat plate support surface portion corresponding to the support surface portion of the hose connector on the inner circumferential surface at the same time as forming an insertion groove and a support jaw, and a fastener formed on the inner circumferential edge at the rear end.

However, such a conventional connection structure is inconvenient for the joining and disengagement work because the fastening nut must be screwed to the hydraulic port when the hydraulic hose is connected to the hose connector and then coupled to the hydraulic port formed in the hydraulic device or hydraulic tank. There were limits.

In addition, when drilling using the Reverse Circulation Drill method, a hydraulic hose is connected to operate the hydraulic machine of the drilling rod. When the hydraulic hose is used as described above, the hydraulic hose is exposed to the outside, thereby drilling There was also a problem that was broken in the process.

Therefore, improvement is needed.
