Detailed Description

in order to make the technical means, creation features, achievement purposes and functions of the present invention easy to understand, the present invention is further described below with reference to the following embodiments.

Referring to fig. 1, the tapered clip type anchorage of the present embodiment is used for clamping a strand 1 to achieve traction or tension of the strand 1. Specifically, the tapered clip anchor comprises an anchor sleeve 5 and a tapered clip 2.

the anchor sleeve 5 is provided with a tapered hole along the axial direction. In this embodiment, ground tackle sleeve 5 includes first ground tackle sleeve 3 and second ground tackle sleeve 4, and first ground tackle sleeve 3 and second ground tackle sleeve 4 all are equipped with the holding tank, and the radius of two holding tanks all enlarges gradually, and two holding tanks constitute the bell mouth. The first anchor sleeve 3 and the second anchor sleeve 4 are detachably connected by a fastener to facilitate the installation and removal of the tapered clip 2.

Specifically, the fastener includes a screw 6 and a nut 7. Fixing holes are formed in the first anchor sleeve 3 and the second anchor sleeve 4, the screw 6 penetrates through the fixing holes of the first anchor sleeve 3 and the fixing holes of the second anchor sleeve 4, and then the first anchor sleeve 3 and the second anchor sleeve 4 are screwed up through the nuts 7. In this embodiment, the two sides of the first anchor sleeve 3 and the second anchor sleeve 4 are connected by fasteners, which can ensure the stability of the clamping force provided by the first anchor sleeve 3 and the second anchor sleeve 4. It will be appreciated that the fasteners may take other forms, such as screws.

The conical clamping pieces 2 are arranged in the conical holes, and the plurality of conical clamping pieces 2 are uniformly distributed along the circumferential direction of the anchor sleeve. The cavity that a plurality of toper clamping pieces 2 enclose is used for accomodating strand 1, and a plurality of toper clamping pieces 2 surround around strand 1 in order to press from both sides the tight fixed with strand 1. In the present embodiment, the number of the tapered clip pieces 2 is three, and all of the three tapered clip pieces 2 are arc-shaped. It is understood that when the number of the tapered jaws 2 is different, the arc degree of the tapered jaws 2 can be specifically adjusted according to the number of the tapered jaws 2.

Referring to fig. 2, in this embodiment, the first anchor sleeve 3 and the second anchor sleeve 4 are provided with receiving grooves, the radii of the two receiving grooves are gradually increased, the two receiving grooves form a tapered hole, and the surface of the tapered clip 2 contacting the anchor sleeve 5 is an inclined surface matching with the side wall of the tapered hole of the anchor sleeve 5. In the process that the conical clamping piece 2 slides along the side wall of the conical hole, the inner diameter of a cavity surrounded by the conical clamping piece 2 can be adjusted to adapt to the cable strands 1 with different diameters.
