As shown in Figure 1, in the first embodiment, rigidity weakening structure also comprises circumferential groove in its end portion 214.Circumferential groove in its end portion 214 is arranged on the root of one end near driving section 22 of the section of collapsing 21.Wherein, the cross section of circumferential groove in its end portion 214 is circular arc, and still, the cross section of this circumferential groove in its end portion 214 can be also U-shaped, rectangle, other shape such as parabola shaped.But concentrate in order to reduce stress, the cross section of circumferential groove in its end portion 214 adopts the curvilinerar figure seamlessly transitting more favourable.
Although rigidity weakening structure comprises radial hole 213 and circumferential groove in its end portion 214 in the first embodiment, those skilled in the art will envision that simultaneously, only adopt one of radial hole 213 and circumferential groove in its end portion 214 also can realize the effect that weakens the section of collapsing 21 rigidity.
As shown in Figure 1, in the first embodiment, drive section 22 to comprise the first screw thread 221.Lock sleeve 10 also comprises the second screw thread 121 coordinating with the first screw thread 221.Core body 20 moves back and forth in the axial direction by the cooperation of the first screw thread 221 and the second screw thread 121.
In order to facilitate the first screw thread 221 and the second screw thread 121 to screw, the first driving plane that is provided for coordinating with spanner in section 22 can driven; And/or the second driving plane that is provided for coordinating with spanner on lock sleeve 10.For example, in the first embodiment, be provided with at the second end of core body 20 six driving planes that hexagon head 222, the first driving planes are hexagon head.
Below in conjunction with Fig. 2, the utility model the second embodiment's rope fixture is further illustrated.
As shown in Figure 2, in the second embodiment's rope fixture, with the first embodiment in the same manner, the section of collapsing 21 is extended towards axial the second end from the end face of the axial first end of core body 20.Drive second end of section 22 from the section of collapsing 21 to core body 20 to extend.Comprise rigidity weakening structure in the section of collapsing 21 near the one end that drives section 22.This rigidity weakening structure is identical with the first embodiment, can be with reference to the first embodiment's relevant portion.
Different from the first embodiment, the second embodiment's driving mode changes to some extent.
As shown in Figure 2, in the second embodiment, drive section 22 comprise lug boss and with the spaced in the axial direction retainer of lug boss.And rope fixture also comprises driving casing 30.Driving casing 30 comprises cylindrical shell 31 and the cylinder end 32.The cylinder end 32, comprises and drives section 22 axial holes that are slidably matched, and lug boss and retainer all have at least a portion to be positioned at the radial outside of axial hole, and lug boss and retainer be positioned at respectively tin at the bottom of 32 axial both sides.Cylindrical shell 31 also comprises the 3rd screw thread 311.Lock sleeve 10 also comprises the 4th screw thread 19 coordinating with the 3rd screw thread 311.Core body 20 moves back and forth in the axial direction by the cooperation of the 3rd screw thread 311 and the 4th screw thread 19.
In the first embodiment, although can realize fixing, adjust and dismounting of rope, but, because driving section 22 and the section of collapsing 21 of core body 20 are synchronously rotated, therefore, rope is fixed tightlyer, and required driving force is larger, and in the later stage of locking operation, because the effect rope of frictional force can rotate with core body 20.And in the second embodiment, be provided with driving casing 30, by the cooperation between driving casing 30 and lug boss and retainer, relatively rotating between driving casing 30 and lock sleeve 10 is converted into the straight line motion between core body 20 and lock sleeve 10, and therefore, core body 20 needn't rotate substantially, driving force ratio the first embodiment required in the second embodiment is more stable, can not fix to such an extent that tightly acutely increase because of rope, and rope also can not rotate.
In order to facilitate the 3rd screw thread 311 and the 4th screw thread 19 to screw, the 3rd driving plane that can be provided for coordinating with spanner on driving casing 10, and/or on lock sleeve 10, be provided for the moving plane of 4 wheel driven coordinating with spanner.For example, in a second embodiment, on driving casing 10, be provided with hexagon head 18, on lock sleeve 10, be provided with hexagon head 312.
In addition, as shown in Figure 2, the 4th screw thread 19 is arranged on the outer circumferential face of lock sleeve 10.Rope fixture also comprises locking nut 40, and locking nut 40 comprises the 5th screw thread coordinating with the 4th screw thread 19.After the 3rd screw thread 311 and the 4th screw thread 19 screw, locking nut 40 can be threaded to the corresponding end-faces butt of driving casing 10 and compress, can prevent that driving casing 10 from getting loose from lock sleeve 10, thereby obtain lasting fixed effect.
As shown in Figure 2, preferably, lug boss is annular boss 229.In addition preferably, drive section 22 to comprise snap ring groove, retainer comprises stop ring 228, and stop ring 228 is arranged in snap ring groove.Annular boss 229 and stop ring 228 are ring-type, can make driving casing 30 offer the axial force of core body 20 more even.
Above embodiment should not form restriction of the present utility model.For example: in above the first embodiment and the second embodiment, the quantity that collapses seam is four, still, collapsing seam also can be for other quantity be if two, three or five are with first-class; In the time driving core body to-and-fro motion by screw-thread fit, the setting position of screw thread can change as required, for example, in the first embodiment, also internal thread can be arranged at and drive section upper, and outside thread is arranged on lock sleeve; In the situation that material meets the demands, rigidity weakening structure is optional, or can adopt the rigidity weakening structure of other form, as offered stiffness tuning hole in the two adjacent sections of collapsing that collapse between seam; The first taper type surface and the second taper type surface can be round platforms, can be also the frustum of a pyramids, if the frustum of a pyramid, the quantity of the rib of the frustum of a pyramid is preferably identical with the quantity that collapses seam and collapse bight of stitching in the frustum of a pyramid etc.
Known according to above description, the above embodiment of the utility model can realize following technique effect: this rope fixture is suitable for often adjusting the demand of rope fixed position.Further, this rope fixture also has installing/dismounting advantage eaily again.
The foregoing is only preferred embodiment of the present utility model, be not limited to the utility model, for a person skilled in the art, the utility model can have various modifications and variations.All within spirit of the present utility model and principle, any amendment of doing, be equal to replacement, improvement etc., within all should being included in protection domain of the present utility model.
