Described dragon's paw formula pipe joint, its further characteristics be, the end of each jaw of clamping part has described hook portion, and these hook portions are hooked the outer end of sealing cover.
Described dragon's paw formula pipe joint, its further characteristics be, is provided with the joggle portion of annular in the described through hole, and the inner of described sealing shroud also is provided with the joggle portion of annular, the joggle portion joggle of the joggle portion of described sealing shroud and described through hole.
Described dragon's paw formula pipe joint, its further characteristics are that the inwall of the outer end of described sealing shroud is thicker than the inwall of the remainder of described sealing shroud.
Described dragon's paw formula pipe joint, its further characteristics are that in described cable insertion section, described clamping part connects described threaded joints.
Described dragon's paw formula pipe joint, its further characteristics be, also comprises the nut of the end with convergent, and the threaded joints that this nut and described cable insert section is threaded and the described clamping part of terminal banding of its convergent.
Described dragon's paw formula pipe joint, its further characteristics are that the end of nut exposes described hook portion of hooking described sealing shroud.
Described dragon's paw formula pipe joint, its further characteristics are that the external form of described clamping part is the circular cone stage body.
Described dragon's paw formula pipe joint, its further characteristics are that described device linkage section and described cable insert Duan Youyi shaft shoulder portion and separate.
Described dragon's paw formula pipe joint, its further characteristics be, a side that is positioned at described device linkage section of described shaft shoulder portion is formed with the step that is used to place a sealing ring, and the sealing circle is axially exceeding this step.
The beneficial effects of the utility model are: this through-hole wall is bonded with sealing shroud, sealing cover and this through hole become one, the sealing cover is isolated with gap between the jaw of this clamping part and through hole inner sealing, has hook portion to the small part jaw, because it is bonding that sealing shroud and through hole are integral ground, and sealing shroud is hooked by hook portion, thereby just can not there be the problem of poor sealing between clamping part and the sealing shroud, when between sealing shroud and cable, being formed sealing surface by lock ring, sealing shroud is also located well, thereby make the sealing property of sealing shroud be further improved, and jaw has also applied chucking power on the surface of cable, makes that the connection between pipe joint and the cable is more firm.
Description of drawings
Fig. 1 is the installation diagram of an embodiment of the present utility model.
Fig. 2 is a decomposition view embodiment illustrated in fig. 1.
Embodiment
As depicted in figs. 1 and 2, dragon's paw formula pipe joint of the present utility model comprises that a device linkage section 10 and a cable insert section 20.Cable inserts section 20 and comprises a threaded joints 21 and a clamping part 22.Clamping part 22 comprises a plurality of jaws 220, and these jaws 220 are one and are circular layout, and as can be seen from Figure 1, the external form of clamping part 22 is the frustum of a cone bodily form.In the embodiment shown in fig. 1, threaded joints 21 is connected with clamping part 22.Device linkage section 10 and cable insert section 20 and are separated by a shaft shoulder portion 30.Device linkage section 10 is used for being connected with the device of a connection cable, and cable insertion section 20 is used to insert a cable.Device linkage section 10 and cable insert section 20 to be run through by a through hole 50, also promptly inserts the cables that section 20 inserts from cable and can pass from through hole 50.Sealing shroud 60 is bonded in the through hole 50, and becomes one with through hole 50, and is promptly inseparable.In the embodiment shown in fig. 1, the inner of sealing shroud 60 is positioned at the through hole of threaded joints 21 correspondences, and the hook portion 221 that the outer end is held the jaw 220 of portion 22 is hooked, and the hook portion 221 of jaw 220 mainly is used for promptly cable.Sealing shroud 60 is isolated with gap between the jaw 220 and through hole 50 inner sealings, and promptly fluid can not enter in the through hole 50 from jaw 220 outsides.The inner of sealing shroud 60 has joggle portion 62, and correspondingly the inside of through hole 50 has joggle portion 22, joggle portion 22 joggles in the joggle portion 62 of sealing shroud 60 and the through hole 50.The inwall of the outer end 61 of sealing shroud 60 is thicker than the inwall of the remainder of sealing shroud 60.See figures.1.and.2 simultaneously, after nut 40 and threaded joints 21 are tightly connected, the end 410 of the convergent of nut 40 is with banding clamping part 22, the jaw 220 of clamping part 22 is because radially inwardly contraction of strain, promptly be inserted into the cable in the through hole 50, and the hook portion 221 of jaw 220 also applies chucking power on cable, cable and pipe joint just can slide relative, the strain of the thicker inwall of the outer end 61 by sealing shroud 60 forms sealing between sealing shroud 60 and cable (not shown).When the left end of Fig. 1 is watched, can see that the end of nut 40 exposes the hook portion 221 of hooking sealing shroud 60.
