Detailed Description
The invention is further described below with reference to the following figures and examples:
the utility model discloses a hose clamp sleeve joint, which is shown in figures 1-5,
the clamp sleeve comprises a clamp sleeve 1, a connector 2 and a hose 3, wherein the clamp sleeve 1 is of an annular structure, an internal thread part 11 is arranged above the inner wall of the clamp sleeve 1, a locking part 12 is arranged below the inner wall of the clamp sleeve, and the locking part 12 is of a conical structure with the inner diameter gradually increasing from top to bottom;
the joint 2 is of a tubular structure, and an air passage 4 communicated with the inner cavity of the hose 3 is axially arranged on the joint; the joint 2 comprises an external connection section 21 and a pagoda section 22, and an external thread part 23 which is in matched threaded connection with the internal thread part 11 is arranged below the outer wall of the external connection section 21; the pagoda section 22 is of a conical structure with the outer diameter gradually decreasing from top to bottom, and the top end of the hose 3 is sleeved outside the pagoda section 22; the inner diameter of the hose 3 is greater than the smallest outer diameter of the pagoda segment 22 and less than the largest outer diameter of the pagoda segment 22; the external diameter of hose 3 is greater than the minimum internal diameter of locking portion 12, and the present case is with hose 3 suit in the outside of pagoda section 22, then drive locking portion 12 through the mode that the screw thread was tightened between internal thread portion 11 and the external screw thread portion 23 on the joint 2 of cutting ferrule 1 inner wall top and press the locking gradually with the outer wall of hose 3 to can lock hose 3 fast, and the present case is installed by the outer end embolia joint 2 of external section 21 at the connecting process cutting ferrule 1, compare in the tradition need before hose and pagoda section are connected, first the cutting ferrule suit in the hose outside, the installation and the dismantlement of present case are all more convenient and simple.
The working principle is as follows: the locking of the hose 3 is a variable distance between the maximum outer diameter of the pagoda segment 22 and the inner wall of the locking part 12, for example, when the wall thickness of the hose 3 is X, after the internal thread part 11 of the ferrule 1 and the external thread part 23 on the external section 21 are tightened, the distance between the maximum outer diameter of the pagoda segment 22 and the inner wall of the locking part 12 is 0.5X, and the locking is realized by flattening the hose 3 to half the wall thickness. The movement stroke of the cutting sleeve 1 is as follows: the clamping sleeve 1 is used for gradually tightening the hose 3 in a threaded tightening mode, the stroke is from X-0.5X, namely, the clamping sleeve 1 is at the initial position of the thread, the gap between the locking part 12 and the maximum outer diameter of the pagoda section 22 is not less than X, and after the thread is locked, the gap between the locking part 12 and the maximum outer diameter of the pagoda section 22 is not more than 0.5X.
Further, a transition section 24 is arranged between the external connection section 21 and the pagoda section 22, the transition section 24 is of an annular structure, and the outer diameter of the transition section 24 is smaller than the maximum outer diameter of the pagoda section 22; the transition groove 25 is defined by the outer wall of the transition section 24, the bottom end face of the external section 21 and the top end face of the pagoda section 22, and by the arrangement of the transition groove 25, when the locking portion 12 gradually locks and extrudes the outer wall of the hose 3, the top end of the hose 3 is gradually pressed into the transition groove 25 above the inner wall of the locking portion 12, so that the hose 3 is bent to a certain degree, and the hose 3 is better locked.
Further, the external diameter of hose 3 is less than the biggest internal diameter of locking portion 12 for cutting ferrule 1 installs more easily, and when locking portion 12 of cutting ferrule 1 passed through the screw thread and moved from top to bottom, hose 3 can not be blockked by the bottom end face of cutting ferrule 1.
Further, the middle of the outer wall of the cutting ferrule 1 is provided with an annular bulge 5 which is integrally formed, so that a user can rotate the cutting ferrule 1 conveniently, and preferably, the outer wall of the annular bulge 5 is provided with a knurl.
Further, a sealing ring groove for sleeving the sealing ring 6 is formed above the outer wall of the external connection section 21; and a retainer ring groove for sleeving the steel wire retainer ring 7 for the shaft is arranged below the seal ring groove, so that the connection between the external section 21 and an external inflating device is more sealed.
Further, the top of external section 21 is the toper structure that the external diameter from top to bottom increases gradually for external section 21 is connected with outside aerating device more easily, thereby makes aerating device aerify hose 3 via air flue 4.
The first embodiment is as follows: as shown in fig. 5, the ferrule 1 has an outer diameter of 8.2mm and the internal thread portion 11 is M7 x 0.75/6h internal thread
The major diameter is 7mm, and the bottom hole is 6.3mm; the maximum inner diameter of the locking part 12 is 7.7mm, and the minimum inner diameter is 7mm;
the external section 21 of the joint 2 has an outer diameter of 5.9mm and the air passage 4 has an inner diameter of 2mm; the external thread part 23 is M7 x 0.75/6g external thread with the large diameter of 6.8mm and the small diameter of 6.0mm. The external diameter of joint 2 and the external diameter of cutting ferrule 1 all compare traditional cutting ferrule and connect and have reduced a lot to save the material, can make the cutting ferrule connect littleer, use in a flexible way in narrow and small space more easily.
The embodiment of the present invention discloses a preferred embodiment, but not limited thereto, and those skilled in the art can easily understand the spirit of the present invention according to the above-mentioned embodiment, and make different applications and changes, but do not depart from the spirit of the present invention, all of which are within the protection scope of the present invention.
