Detailed Description
In order to make the technical problems, technical solutions and advantageous effects to be solved by the present invention more clearly apparent, the present invention is further described in detail below with reference to the accompanying drawings and embodiments. It should be understood that the specific embodiments described herein are merely illustrative of the invention and are not intended to limit the invention.
Referring to fig. 1 and fig. 2, a fastener falling-prevention type suture connecting clip provided by the invention will be described. The anti-falling type parallel-connection clamp for the fastener comprises a first clamping piece 13, a second clamping piece 14, a bolt 4 and a nut 3, wherein the first clamping piece 13 is provided with a first penetrating hole 6 and a first connecting part; the second clamping piece 14 is connected with the first clamping piece 13, a wire placing space is formed between the first clamping piece 13 and the second clamping piece 14, and a second penetrating hole 8 is formed in the second clamping piece 14; a screw rod of the bolt 4 penetrates through the first penetrating hole 6 and the second penetrating hole 8, a nut of the bolt 4 is provided with a second connecting part, and the second connecting part is inserted with the first connecting part and used for limiting the rotation of the bolt 4; the nut 3 is in threaded connection with the penetrating end of the screw rod and is used for enabling the first clamping piece 13 and the second clamping piece 14 to clamp the wires.
Compared with the prior art, when the anti-falling type parallel-connection clamp for the fastener is used, before high-altitude operation, a lead is placed between a first clamping piece 13 and a second clamping piece 14 which are mutually connected, and then a screw of a bolt 4 sequentially penetrates through a first penetrating hole 6 and a second penetrating hole 8 from the outer side of the first clamping piece 13 and penetrates out of the second penetrating hole 8; and then connecting the nut 3 with the penetrating end of the bolt 4, but not screwing the nut 3 at the moment, and finishing the pre-installation of the fastener anti-falling type cable clamp. When high altitude construction, penetrate the wire and place the space between first holder 13 and second holder 14, when placing or connect the completion back, the position of rotatory bolt 4 makes first connecting portion on the first holder 13 peg graft with the second connecting portion on the bolt 4 nut, and bolt 4 can not rotate again after the grafting, then screws up nut 3. Because the rotation of the bolt 4 is limited, an operator does not need to fix the bolt 4 by the other hand, and the nut 3 can be conveniently and quickly screwed in high altitude to finish the installation. The anti-falling type parallel clamp of the fastener can be assembled in advance before high-altitude operation, and when the high-altitude operation is carried out, the first connecting part and the second connecting part are additionally arranged, so that the rotation freedom degree of the bolt 4 is limited when the nut 3 is screwed down, the installation is more convenient when the high-altitude operation is carried out, the bolt 4 cannot fall from the high altitude due to the rotation and unstable catching of the bolt 4, and the potential safety hazard of the ground is reduced.
In the prior art, the wire clamp is an iron or aluminum metal accessory which can be fixed on a wire, most of the wire clamp needs to bear larger pulling force in operation, and some wire clamps need to ensure good contact in the electrical aspect.

The embodiment before is preventing weighing down the type and lead to the fastener and is installing in advance, for the convenient packing into of follow-up wire, nut 3 can not be screwed up, and this just before making first connecting portion and second connecting portion joint, bolt 4 can move along bolt 4's axis direction, and bolt 4 still can rotate to when high altitude construction, still need rotatory bolt 4 to carry out the joint counterpoint, long time that has increased high altitude construction.
In this embodiment, the side wall of the protruding ridge 5 is provided with a clamping groove 7, the groove 9 is internally provided with a clamping head 10, and the clamping head 10 is clamped with the clamping groove 7. When preventing weighing down type and lead to the clamp to a fastener and installing in advance, with first connecting portion and second connecting portion joint, simultaneously with dop 10 and draw-in groove 7 joint, it is spacing all to the rotation degree of freedom of bolt 4 along the axis and along the removal degree of freedom of self axis, guaranteed bolt 4's fixed to during the high altitude construction, penetrate a fastener and prevent weighing down type and lead to the clamp back, only need screw up nut 3 can, make high altitude construction more high-efficient.
Referring to fig. 2 to 5, an accommodating cavity is formed in a side wall of a groove 9, a spring 11 and a chuck 10 are arranged in the accommodating cavity, the chuck 10 is slidably arranged in the accommodating cavity, one end of the spring 11 is connected with the chuck 10, the other end of the spring 11 is connected with a cavity wall of the accommodating cavity, and the spring 11 is used for pushing the chuck 10 to be inserted into the slot 7.
In this embodiment, be equipped with on the lateral wall of recess 9 and hold the chamber, hold the intracavity and be equipped with spring 11 and dop 10, dop 10 slides and locates and hold the chamber, and spring 11 one end links to each other with dop 10, and the other end links to each other with the chamber wall that holds the chamber. When the first connecting part and the second connecting part are clamped, the clamping head 10 is retracted into the accommodating cavity under the blocking of the side wall of the convex edge 5, and the spring 11 is stressed and compressed at the moment; when the first connecting portion is clamped with the second connecting portion, the clamping head 10 is opposite to the clamping groove 7, and at the moment, the clamping head 10 extends into the clamping groove 7 under the elastic action of the spring 11 to complete the installation and fixation of the bolt 4. If need dismantle bolt 4, pull down nut 3, then pull out bolt 4 through external force, under the external force effect, dop 10 withdraws and holds the chamber to can pull out bolt 4.
Referring to fig. 2 to 5, as an embodiment of the anti-falling type suture connecting clip for a fastener according to the present invention, inclined surfaces 12 are provided at the upper end and the lower end of the chuck 10 along the depth direction of the groove 9.
In this embodiment, the upper end and the lower end of the chuck 10 are provided with inclined surfaces 12 along the depth direction of the groove 9. When the bolt 4 needs to be pulled out, the inclined surface 12 at the upper end is contacted with the edge of the clamping groove 7, when the bolt 4 is pulled by external force, the inclined surface 12 at the upper end separates out force in the radial direction of the bolt 4 from pulling force in the axial direction of the bolt 4, and the radial force pushes the chuck 10 to be retracted into the accommodating cavity. The lower inclined surface 12 acts on the same principle as the upper inclined surface 12 when the bolt 4 is assembled. The upper end and the lower end of the clamping head 10 are provided with inclined planes 12 which are convenient for the disassembly and assembly of the bolt 4.
The above description is only for the purpose of illustrating the preferred embodiments of the present invention and is not to be construed as limiting the invention, and any modifications, equivalents and improvements made within the spirit and principle of the present invention are intended to be included within the scope of the present invention.
