Detailed ways

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

As shown in FIGS. 1-6 , the solution provided in this embodiment includes a base 1 , a pressing base 2 , a T-shaped screw 3 , a pressing shaft 4 and a pressing sleeve 5 . One end of the base 1 is the hinged end 16 of the base, the middle of the base 1 is provided with an accommodation groove 11 for accommodating the wire rope, one end of the pressure base 2 is the hinged end 24 of the pressure base, and the middle of the base 2 is also provided with an accommodation groove for accommodating the wire rope Slot 11, the hinge end 16 of the base and the hinge end 24 of the base are hinged through the pin 12, the base 2 is buckled above the base 1, when the base 2 is buckled with the base 1, the accommodating groove 11 is stuck with two wire ropes that need to be fixed .

The other end of the base 1 is provided with a through base through groove 15, the other end of the pressure base 2 is provided with a through through base through groove 23, and the other end of the pressure base 2 is also provided with a pressure base groove 21. There is a base groove 13 above the other end.

The T-shaped screw 3 includes 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 an external thread. 32 is connected to the pressing sleeve 5 after passing through the through groove 23 of the pressing seat, the through groove 15 of the base, and the pressing shaft 4 in sequence. The pressing shaft 4 is provided with a pressing shaft through hole 43 , the vertical part 32 penetrates the pressing shaft through hole 43 , the pressing sleeve 5 is a sleeve structure, and the pressing sleeve 5 is provided with an internal thread corresponding to the external thread of the vertical part 32 . The wall is provided with a torsion bar 51 protruding outward, and the vertical part 32 and the pressing sleeve 5 are fixed by means of threaded connection. Therefore, in fact, the vertical part 32 does not need to be provided with all external threads, and only a section at the end of the vertical part 32 is used. It is sufficient to set the external thread where it needs to be threadedly connected with the pressure sleeve 5. In addition, the shape of the pressing shaft 4 needs to correspond to the shape of the base groove 13 to ensure that the pressing shaft 4 can be crimped into the base groove 13 .

The traditional wire rope clamp usually needs to use two components to clamp the wire rope, and set screws at both ends of the component to clamp the wire rope. To the extent that it requires a wrench, it is difficult for one person to complete the installation. The collet in this embodiment only needs to tighten the screw at one end, and the installation can be completed by one person. What's more, in this embodiment, there is also a torsion bar 51 on the pressing sleeve 5, which can be directly used as a wrench without any additional Using a wrench saves operating tools and saves operating time. It should be noted that the torsion bar 51 in this embodiment cannot be provided by the traditional wire rope clamp, because the traditional wire rope clamp needs to install screws at both ends. In this embodiment, it is only meaningful to fix with a single screw.

In this embodiment, a base groove 13 is provided on the base 1, and a pressing shaft 4 is used to set the pressing shaft 4 between the base 1 and the pressing sleeve 5, in order to enhance the clamping force of the chuck. In order to ensure that the accommodating grooves 11 can clamp the wire rope, the clamping distance between the two accommodating grooves 11 must be smaller than the diameter of the two wire ropes, which makes the base 1 and the pressing base 2 form an angle with the rotation axis as the intersection point, and the pressing shaft The existence of 4 can fully guarantee the force bearing area of the pressure sleeve 5 . Specifically, the base groove 13 in this embodiment is in a sub-arc shape, that is, the depth of the arc is smaller than the radius of the arc, one side of the pressing shaft 4 is set as the inferior arc surface 41 corresponding to the base groove 13, and the other side of the pressing shaft 4 It is set as the horizontal plane 42, so that no matter how large the angle formed between the base 1 and the pressing base 2 with the rotation axis as the intersection point, it can ensure that the stress surface of the pressing sleeve 5 is parallel and coincident with the horizontal plane 42 of the pressing shaft 4. The arc surface 41 is concentric and coincident with the base groove 13 , so that the stress effect of the pressing sleeve 5 , the pressing shaft 4 and the base 1 is optimal, and the clamping force effect of the chuck is enhanced. At the same time, the pressing shaft 4 is stuck in the groove 13 of the base and can also play a role in restricting the swing of the T-shaped screw 3 .

In this embodiment, the length of the through groove 23 of the pressure seat is greater than the length of the horizontal portion 31 , the width of the through groove 23 of the pressure seat is greater than the width of the horizontal portion 31 and smaller than the length of the horizontal portion 31 , and the tail end of the vertical portion 32 is provided with a lifting ring 33. On the one hand, this arrangement can ensure that the T-shaped screw 3 can form a whole with the base 1 and the pressing seat 2, and will not fall off and separate, and on the other hand, it can also improve the installation speed. When in use, open the base 1 and the pressure seat 2 as shown in Figure 1, and after the accommodating groove 11 covers the wire rope to be fixed, turn the T-shaped screw 3 so that the horizontal part 31 passes through the through-groove 23 of the pressure seat, and then put the T-shaped screw 3 Rotate 90°, so that the horizontal part 31 is engaged with the groove 21 of the pressing seat, and the pressing sleeve 5 can be fixed by rotating the torsion bar 51. It is not worried that the T-shaped screw 3 will fall off when one person installs it, and the installation steps are simplified. , improve the installation efficiency. In addition, the lifting ring 33 can also play the role of being convenient for carrying and hanging.

Preferably, the pressure seat groove 21 can be set in an arc shape, and the horizontal portion 31 can be set in a cylindrical shape, which is not only convenient for the processing of the parts, but also for the installation during use. It is best that the base 1, the pressing seat 2, the T-shaped screw 3, the pressing shaft 4 and the pressing sleeve 5 are all made of stainless steel, which is durable and can guarantee the strength.

In addition, the present invention also provides a preferred solution, which is to lengthen the depth of the accommodating groove 11 , and at the same time, the two ends of the accommodating groove 11 of the base 1 are provided with protrusions 14 , and the two ends of the accommodating groove 11 of the pressure seat 2 are provided with protrusions 14 . The pits 22 corresponding to 14 are formed. Because the copper wire rope is to be fixed with multiple chucks side by side, the number of chucks can be greatly reduced by using this preferred structure. The effect of 14 and the pit 22 on the wire rope can greatly improve the clamping force on the wire rope.

Finally, it should be noted that the above embodiments are only used to illustrate the technical solutions of the present invention, not to limit the protection scope of the present invention. Although the present invention has been described in detail with reference to the preferred embodiments, those of ordinary skill in the art should understand that , the technical solutions of the present invention may be modified or equivalently replaced without departing from the spirit and scope of the technical solutions of the present invention.
