Detailed Description

The present invention will be described in detail with reference to specific examples.

As shown in fig. 1-6, the solution provided by the present embodiment includes a base 1, a pressing base 2, a T-shaped screw 3, a pressing shaft 4 and a pressing sleeve 5. Wherein the one end of base 1 is base hinged end 16, the middle part of base 1 is equipped with the recess 11 that holds wire rope, the one end of pressing seat 2 is for pressing a hinged end 24, the middle part of pressing seat 2 is equipped with the recess 11 that holds wire rope equally, base hinged end 16 is articulated through round pin axle 12 with pressing a hinged end 24, press seat 2 to detain and press in base 1 top, when pressing seat 2 and base 1 lock, hold recess 11 and block two wire rope that need be fixed.

The other end of base 1 is equipped with the base that link up and leads to groove 15, and the other end of pressing seat 2 is equipped with the pressure seat that links up and leads to groove 23, presses the other end top of seat 2 still to be equipped with simultaneously and presses a recess 21, and the other end top of base 1 is equipped with base recess 13.

The T-shaped screw 3 comprises a horizontal portion 31 and a vertical portion 32, the horizontal portion 31 and the vertical portion 32 form a T shape, the vertical portion 32 is provided with external threads, the horizontal portion 31 is buckled on the pressing seat groove 21, and the vertical portion 32 sequentially penetrates through the pressing seat through groove 23, the base through groove 15 and the pressing shaft 4 and then is connected with the pressing sleeve 5. Wherein establish the last pressure axle through-hole 43 of pressing 4, vertical portion 32 runs through pressure axle through-hole 43, presses cover 5 to be sleeve structure, presses cover 5 to be equipped with the internal thread that corresponds with vertical portion 32 external screw thread, and the lateral wall of pressing cover 5 is equipped with the torsion bar 51 that outwards stretches out, and vertical portion 32 adopts threaded connection fixed with pressing cover 5, so, actually vertical portion 32 also need not all to set up the external screw thread, only need be in vertical portion 32 end one section need with press cover 5 threaded connection's place establish the external screw thread can. In addition, the shape of the pressing shaft 4 needs to correspond to the shape of the base groove 13, so that the pressing shaft 4 can be buckled and pressed into the base groove 13.

Traditional wire rope presss from both sides need to use two subassemblies to carry wire rope usually to establish the screw respectively at the both ends of this subassembly and in order to carry wire rope, because wire rope need bear great pulling force usually, for the tight degree that reaches the requirement of guarantee wire rope clamp, need use the spanner not to say, also hardly accomplish the installation alone. The chuck in the embodiment can be completely installed by one person only by screwing a screw at one end, and the torsion bar 51 is further arranged on the pressing sleeve 5 in the embodiment, so that the chuck can be directly used as a wrench without additionally using the wrench, thereby saving operating tools and saving operating time. It should be noted that the torsion bar 51 in the present embodiment is not possessed by the conventional wire rope clip, because the conventional wire rope clip requires screws to be installed at both ends, if a wrench is welded on the screws, interference will inevitably occur during rotation, and therefore, it is only meaningful to adopt a single screw for fixing in the present embodiment.

In this embodiment, the base 1 is provided with a base groove 13, and the pressing shaft 4 is used, and the pressing shaft 4 is arranged between the base 1 and the pressing sleeve 5, which is to enhance the clamping force of the chuck. In order to ensure that the accommodating grooves 11 can clamp the steel wire ropes, the clamping distance of the two accommodating grooves 11 is required to be smaller than the diameters of the two steel wire ropes, so that the base 1 and the pressing seat 2 form an included angle by taking the rotating shaft as an intersection point, and the existence of the pressing shaft 4 can fully ensure the stress area of the pressing sleeve 5. Specifically, the base groove 13 in this embodiment is in the shape of an inferior arc, that is, the depth of the arc is smaller than the radius of the arc, one surface of the pressing shaft 4 is set to be a inferior arc surface 41 corresponding to the base groove 13, and the other surface of the pressing shaft 4 is set to be a horizontal surface 42, so that no matter how large the number of degrees of the included angle formed by the base 1 and the pressing base 2 by using the rotating shaft as the intersection point is, the stress surface of the pressing sleeve 5 can be ensured to be parallel to and coincident with the horizontal surface 42 of the pressing shaft 4, and meanwhile, the inferior arc surface 41 of the pressing shaft 4 is concentric with the base groove 13 and coincident with each other, so that the stress effects of the pressing sleeve 5, the pressing shaft 4. Meanwhile, the pressing shaft 4 is clamped in the base groove 13 and can also play a role in limiting the swing of the T-shaped screw rod 3.

The length of the pressing seat through groove 23 in this embodiment is greater than the length of the horizontal portion 31, the width of the pressing seat through groove 23 is greater than the width of the horizontal portion 31 and less than the length of the horizontal portion 31, and the tail end of the vertical portion 32 is provided with a hanging ring 33. This kind of setting can ensure on the one hand that T shape screw rod 3 can form a whole with base 1, pressure seat 2, can not drop the separation, and on the other hand can also improve the installation rate. When the steel wire rope fixing device is used, the base 1 and the pressing seat 2 are opened as shown in fig. 1, the accommodating groove 11 is used for sleeving a steel wire rope to be fixed, the T-shaped screw rod 3 is rotated, the horizontal part 31 penetrates through the pressing seat through groove 23, the T-shaped screw rod 3 is rotated by 90 degrees, the horizontal part 31 is clamped on the pressing seat groove 21, the pressing sleeve 5 is rotated through the torsion bar 51, fixing can be achieved, the T-shaped screw rod 3 does not fall off when one person installs the steel wire rope, the installation steps are simplified, and the installation efficiency is improved. In addition, the hanging ring 33 can also be used for carrying and hanging.

Preferably, the pressure seat groove 21 is formed in an arc shape, and the horizontal portion 31 is formed in a cylindrical shape, which facilitates processing of parts and facilitates mounting in use. Preferably, the base 1, the pressing base 2, the T-shaped screw rod 3, the pressing shaft 4 and the pressing sleeve 5 are all made of stainless steel materials, so that the device is durable and can guarantee strength.

In addition, the invention also provides a preferable scheme that the depth of the accommodating groove 11 is lengthened, the two ends of the accommodating groove 11 of the base 1 are provided with the bulges 14, and the two ends of the accommodating groove 11 of the press seat 2 are provided with the pits 22 corresponding to the bulges 14. Because the steel wire rope copper material is fixed, a plurality of chucks are adopted to be fixed side by side, the number of the chucks can be greatly reduced by adopting the optimal structure, although the stress clamping part of the optimal scheme is only arranged at one middle part, the clamping force on the steel wire rope can be greatly improved due to the effect of the bulges 14 at the two ends and the concave pits 22 on the steel wire rope.

Finally, it should be noted that the above embodiments are only used for illustrating the technical solutions of the present invention, and not for limiting the protection scope of the present invention, although the present invention is described in detail with reference to the preferred embodiments, it should be understood by those skilled in the art that modifications or equivalent substitutions can be made on the technical solutions of the present invention without departing from the spirit and scope of the technical solutions of the present invention.
