Description

Technical Field

[0001] The invention belongs to the technical field of electric power devices, and more specifically, relates to a fastener anti-falling and parallel wire clamp. Background Art

[0002] When working on power lines, especially on high-altitude power lines, wire clamps are often used. Currently, parallel groove clamps are commonly used for the non-loaded connection of power line conductors. The parallel groove clamp is provided with an upper clamping plate and a lower clamping plate, and the upper clamping plate and the lower clamping plate are connected by bolts and nuts to clamp the conductor. When working at high altitude with a parallel groove clamp and tightening the nut, the bolt often rotates with the nut, which not only makes the installation inconvenient, but also poses a risk of high-altitude falling during installation. Summary of the Invention

[0003] The purpose of the invention is to provide a fastener anti-falling and parallel wire clamp, aiming to solve the problem that in the existing fastener anti-falling and parallel wire clamp structure, when clamping with bolts and nuts, the bolt often rotates with the nut during high-altitude installation of the nut and bolt threads, which not only makes the installation inconvenient, but also poses a risk of high-altitude falling.

[0004] To achieve the above purpose, the technical solution adopted by the invention is: providing a fastener anti-falling and parallel wire clamp, including a first clamping member, a second clamping member, a bolt, and a nut. The first clamping member is provided with a first through hole and a first connecting portion; the second clamping member is connected to the first clamping member, and a placement space for the conductor is formed between the first clamping member and the second clamping member. The second clamping member is provided with a second through hole; the screw of the bolt passes through the first through hole and the second through hole, and the nut of the bolt is provided with a second connecting portion. The second connecting portion is inserted into the first connecting portion and is used to limit the rotation of the bolt; the nut is threadedly connected to the protruding end of the screw and is used to clamp the conductor by the first clamping member and the second clamping member.

[0005] As another embodiment of this application, the first connecting portion is a groove, and the second connecting portion is a rib.

[0006] As another embodiment of this application, the second connecting portion is a groove, and the first connecting portion is a rib.

[0007] As another embodiment of this application, the first clamping member and the second clamping member are connected by a connecting section, and the first clamping member, the second clamping member, and the connecting section are an integral structure. The connecting section is provided with a plurality of parallel wire grooves for placing the conductor.

[0008] As another embodiment of this application, the first through hole is one of a rectangular hole, an oblong hole, an oval hole, a rhombic hole, or a trapezoidal hole, and the shape of the nut of the bolt is the same as that of the first through hole.

[0009] As another embodiment of the present application, the first mounting hole is a rectangular hole. When the first connecting portion is inserted into the second connecting portion, the length direction of the nut is perpendicular to the length direction of the first mounting hole.

[0010] As another embodiment of the present application, two wire grooves are provided. The cross-section of the connecting section is ω-shaped. The first clamping member is the first end plate, the second clamping member is the second end plate, and the first end plate and the second end plate are respectively arranged at both ends of the connecting section.

[0011] As another embodiment of the present application, a clamping groove is provided on the side wall of the convex rib, a clamping head is provided in the groove, and the clamping head is clamped with the clamping groove. The clamping head and the clamping groove are used to limit the axial movement of the bolt along its own axis.

[0012] As another embodiment of the present application, a receiving cavity is provided on the side wall of the groove. A spring and a clamping head are provided in the receiving cavity. The clamping head is slidably arranged in the receiving cavity. One end of the spring is connected to the clamping head, and the other end is connected to the cavity wall of the receiving cavity. The spring is used to push the clamping head into the clamping groove.

[0013] As another embodiment of the present application, along the depth direction of the groove, inclined surfaces are provided at both the upper end and the lower end of the clamping head.

[0014] The beneficial effect of a fastener anti-falling and parallel wire clamp provided by the present invention is as follows: Compared with the prior art, when the fastener anti-falling and parallel wire clamp of the present invention is used, before high-altitude operation, the wire is first placed between the mutually connected first clamping member and the second clamping member, and then the screw rod of the bolt sequentially passes through the first mounting hole, the second mounting hole from the outside of the first clamping member, and passes out from the second mounting hole; then the nut is connected to the passing-out end of the bolt, but the nut is not tightened at this time, and the pre-installation of a fastener anti-falling and parallel wire clamp is completed. When high-altitude operation is carried out, the wire is inserted into the placement space between the first clamping member and the second clamping member. After the placement or connection is completed, the position of the bolt is rotated so that the first connecting portion on the first clamping member is inserted into the second connecting portion on the bolt nut. After the insertion, the bolt cannot be rotated anymore, and then the nut is tightened. Because the rotation of the bolt is restricted, the operator does not need to fix the bolt with the other hand, so the nut can be tightened conveniently and quickly at high altitude to complete the installation. The fastener anti-falling and parallel wire clamp of the present invention can be pre-assembled before high-altitude operation. When high-altitude operation is carried out, because the first connecting portion and the second connecting portion are added, the rotational freedom of the bolt is restricted when the nut is tightened, making the installation more convenient at high altitude and preventing the bolt from falling from high altitude due to the rotation and unstable grasping of the bolt, reducing the safety hazard on the ground.

[0022] In order to make the technical problems, technical solutions and beneficial effects to be solved by the present invention clearer, the present invention will be further described in detail below with reference to the drawings and embodiments. It should be understood that the specific embodiments described herein are only used to explain the present invention and are not used to limit the present invention.

[0023] Please refer to Figure 1 and Figure 2 simultaneously. Now, a fastener anti-falling and parallel wire clamp provided by the present invention will be described. The fastener anti-falling and parallel wire clamp includes a first clamping member 13, a second clamping member 14, a bolt 4, and a nut 3. The first clamping member 13 is provided with a first mounting hole 6 and a first connecting portion; the second clamping member 14 is connected to the first clamping member 13, and a placement space for the wire is formed between the first clamping member 13 and the second clamping member 14. The second clamping member 14 is provided with a second mounting hole 8; the screw of the bolt 4 passes through the first mounting hole 6 and the second mounting hole 8, and a second connecting portion is provided on the nut of the bolt 4. The second connecting portion is inserted into the first connecting portion and is used to limit the rotation of the bolt 4; the nut 3 is threadedly connected to the protruding end of the screw and is used to clamp the wire by the first clamping member 13 and the second clamping member 14.

[0024] The present invention provides a fastener anti-fall type parallel wire clamp. Compared with the prior art, when in use, before working at high altitude, first place the wire between the first clamp 13 and the second clamp 14 that are connected to each other, then the screw of the bolt 4 passes through the first through hole 6, the second through hole 8, and then passes through the second through hole 8 from the outside of the first clamp 13; then the nut 3 is connected to the through end of the bolt 4, but the nut 3 is not tightened at this time, and the pre-installation of a fastener anti-fall type parallel wire clamp is completed. When working at high altitude, the wire is inserted into the placement space between the first clamp 13 and the second clamp 14. After the placement or connection is completed, the position of the rotating bolt 4 is made so that the first connecting part on the first clamp 13 is plugged with the second connecting part on the nut of the bolt 4. After plugging, the bolt 4 can no longer rotate, and then the nut 3 is tightened. Because the rotation of the bolt 4 is restricted, the operator does not need to fix the bolt 4 with another hand, so the nut 3 can be conveniently and quickly tightened at high altitude to complete the installation. The anti-fall type parallel wire clamp of the fastener of the present invention can be pre-assembled before high-altitude operation. When working at high altitude, because the first connecting part and the second connecting part are added, when the nut 3 is tightened, the rotational freedom of the bolt 4 is restricted, making the installation more convenient during high-altitude operation, and the bolt 4 will not fall from the high altitude due to the rotation or unstable grasping of the bolt 4, thereby reducing the safety hazard on the ground.

[0025] In the prior art, wire clamps are iron or aluminum metal accessories that can be fixed on wires. Most of them need to withstand large tensile forces during operation, and some also need to ensure good electrical contact. Wire clamps are mainly divided into equipment wire clamps, fuse clamps, wire holding clamps, terminal wire clamps, piercing grounding wire clamps, tightening wire clamps, insulation piercing wire clamps, double-headed wire clamps, lead-in wire clamps, etc.

[0026] The parallel groove clamp is a special type of clamp. It is used to connect aluminum stranded wires or steel core aluminum stranded wires with small and medium cross-sections and steel stranded wires of overhead lightning arresters at locations that do not bear tension. It is also used for jumper connections of non-linear pole towers. The power engineering material connection wires are mainly used for connecting wires to each other in power line projects.

[0027] When the parallel groove wire clamp is used for aerial operation, the operator places the wire that is not under tension directly between the upper and lower clamps, and then passes the screw end of the bolt through the two clamps, and connects the nut to the bolt. When the nut and bolt are connected and rotated, because the rotational freedom of the bolt is not restricted, the operator must fix the bolt with one hand and rotate the nut with the other hand, otherwise the fixed connection between the bolt and the nut cannot be achieved, and the operation is very inconvenient. Sometimes, because the operator is slightly loose and fails to fix the bolt, the bolt or other parts of the parallel groove wire clamp will fall off, and the parts falling from high altitude will pose a huge safety hazard to the personnel on the ground.

[0028] In this embodiment, a fastener anti-falling combined wire clamp can be used in the same usage environment as a parallel groove clamp. The invented fastener anti-falling combined wire clamp is applicable to various non-stressed connections in power transmission lines, distribution lines, and low-voltage lines, as well as various non-stressed continuous wiring of power conductors in substations and factory power distribution. It has a wide range of applications and is a commonly used component in the power industry.

[0029] In this embodiment, before high-altitude operation, the pre-installation steps of a fastener anti-falling combined wire clamp are as follows:

[0030] First, insert the bolt 4 into the first clamping member 13 from the outside. The screw rod of the bolt 4 first passes through the first mounting hole 6, and then through the second mounting hole 8. The end of the screw rod passes through the second mounting hole 8 to the outside of the second clamping member 14 for subsequent connection.

[0031] Then, connect the nut 3 to the screw rod from the outside of the second clamping member 14. At this time, the nut 3 is not fully tightened.

[0032] When the operator conducts high-altitude operation with the pre-installed fastener anti-falling combined wire clamp, since the first clamping member 13 and the second clamping member 14 are joined at one end and the nut 3 is not tightened, the wire can be inserted into the placement space from both sides of the first clamping member 13 and the second clamping member 14. Therefore, the high-altitude operation steps are as follows:

[0033] The first step is to insert the wire into the placement space from both sides of the first clamping member 13 and the second clamping member 14.

[0034] The second step is that after the wire is placed or connected, rotate the position of the bolt 4 so that the first connecting portion and the second connecting portion are inserted, thereby restricting the rotational freedom of the bolt 4.

[0035] The third step is to tighten the nut 3 to achieve clamping.

[0036] In this embodiment, since the position of the bolt 4 is rotated so that the first connecting portion and the second connecting portion are inserted, the rotational freedom of the bolt 4 is restricted. Thus, when the nut 3 is tightened, the bolt 4 will no longer rotate with the rotation of the nut 3, enabling the nut 3 to be rotated and tightened conveniently and quickly, reducing the risk of high-altitude falling objects, making the installation more convenient, and more safe and reliable.

[0037] In this embodiment, a flat washer is also sleeved on the protruding end of the screw rod from the second mounting hole 8. One end face of the nut 3 contacts the flat washer, and the nut 3 presses the second clamping member 14 through the flat washer, so that the first clamping member 13 and the second clamping member 14 clamp the wire. The pre-installation steps of the fastener anti-falling combined wire clamp in this embodiment are as follows:

[0038] First, insert the bolt 4 from the outside of the first clamping member 13. The screw rod of the bolt 4 first passes through the first mounting hole 6, then through the second mounting hole 8, and the end of the screw rod passes through the second mounting hole 8 to the outside of the second clamping member 14 for subsequent connection;

[0039] Then, sleeved a plain washer on the protruding end of the screw rod from the second mounting hole 8, and connect the nut 3 to the screw rod from the outside of the plain washer. At this time, the nut 3 is not fully tightened.

[0040] When the operator conducts high-altitude operations with a pre-installed anti-falling and through-wiring clamp for a fastener, the high-altitude operation steps of the operator are as follows:

[0041] First step, the wire can be inserted into the placement space from both sides of the first clamping member 13 and the second clamping member 14;

[0042] Second step, after the wire is placed or connected, rotate the position of the bolt 4 so that the first connecting portion and the second connecting portion are inserted, thereby restricting the rotational freedom of the bolt 4;

[0043] Third step, tighten the nut 3. The nut 3 presses the second clamping member 14 through the plain washer to clamp the wire.

[0044] In this embodiment, a spring washer 11 is also sleeved on the protruding end of the screw rod from the second mounting hole 8. The spring washer 11 contacts the plain washer, and the spring washer 11 is located outside the plain washer. One end face of the nut 3 contacts the spring washer 11. The nut 3 presses the spring washer 11, and then the spring washer 11 presses the plain washer with the pressing force, so that the pressing force is transmitted to the second clamping member 14, and the first clamping member 13 and the second clamping member 14 clamp the wire. The pre-installation steps of an anti-falling and through-wiring clamp for a fastener in this embodiment are as follows:

[0045] First, insert the bolt 4 from the outside of the first clamping member 13. The screw rod of the bolt 4 first passes through the first mounting hole 6, then through the second mounting hole 8, and the end of the screw rod passes through the second mounting hole 8 to the outside of the second clamping member 14 for subsequent connection;

[0046] Then, sleeved a plain washer on the protruding end of the screw rod from the second mounting hole 8, sleeved a spring washer 11 on the protruding end of the screw rod, and the spring washer 11 is located outside the plain washer. Connect the nut 3 to the screw rod from the outside of the spring washer 11. At this time, the nut 3 is not fully tightened.

[0047] When the operator conducts high-altitude operations with a pre-installed anti-falling and through-wiring clamp for a fastener, the high-altitude operation steps of the operator are as follows:

[0048] First step, the wire can be inserted into the placement space from both sides of the first clamping member 13 and the second clamping member 14;

[0049] In the second step, after the wire placement or connection is completed, rotate the position of the bolt 4 so that the first connecting portion and the second connecting portion are inserted, thereby restricting the rotational freedom of the bolt 4;

[0050] In the third step, tighten the nut 3. The nut 3 presses the second clamping member 14 through the spring washer 11 and the plain washer to achieve clamping.

[0051] In this embodiment, a spring washer 11 and a plain washer are added. The nut 3 presses the second clamping member 14 through the spring washer 11 and the plain washer, making the pressing force of the nut 3 on the second clamping member 14 more uniform, so as to ensure that the clamping force of the second clamping member 14 and the first clamping member 13 on the wire is more uniform.

[0052] In this embodiment, the first mounting holes 6 on the first clamping member 13 correspond to the second mounting holes 8 on the second clamping member 14 one by one. A plurality of first mounting holes 6 can be provided and a plurality of second mounting holes 8 are correspondingly provided. A set of bolts 4 and nuts 3 are correspondingly arranged in each group of the first mounting holes 6 and the second mounting holes 8, thereby ensuring the stability of the clamping of the entire anti-falling and wire-passing clamp for fasteners on the wire and better realizing uniform clamping.

[0053] As a specific embodiment of an anti-falling and wire-passing clamp for fasteners provided by the present invention, please refer to Figures 2 to 3 , the first connecting portion is a groove 9 and the second connecting portion is a rib 5.

[0054] In this embodiment, a groove 9 is provided on the first clamping member 13, and a rib 5 is provided on the bottom surface of the nut of the bolt 4. The rib 5 is inserted into the groove 9 to complete the insertion of the first connecting portion and the second connecting portion.

[0055] In this embodiment, the shape of the rib 5 is the same as the shape of the groove 9. The rib 5 is rectangular and the groove 9 is also rectangular.

[0056] In this embodiment, the rib 5 can be in other shapes such as a prism, a triangle, and a circle.

[0057] As a specific embodiment of an anti-falling and wire-passing clamp for fasteners provided by the present invention, please refer to Figures 1 to 2 , the second connecting portion is a groove 9 and the first connecting portion is a rib 5.

[0058] In this embodiment, a rib 5 is provided on the first clamping member 13, and a groove 9 is provided on the bottom surface of the nut of the bolt 4. The rib 5 is inserted into the groove 9 to complete the insertion of the first connecting portion and the second connecting portion, and the insertion of the first connecting portion and the second connecting portion can be quickly realized.

[0059] In this embodiment, when a plurality of bolts 4 are provided on a fastener anti-falling and parallel wire clamp, a long convex rib 5 is provided on the first clamping member 13, and the first through hole 6 penetrates through the first clamping member 13 and the convex rib 5. The plurality of first through holes 6 are arranged at intervals along the length direction of the convex rib 5.

[0060] In this embodiment, the shape of the convex rib 5 is the same as the shape of the groove 9. The convex rib 5 is rectangular, and the groove 9 is also rectangular.

[0061] In this embodiment, the convex rib 5 can also be other shapes such as a polygonal prism, a triangle, and a circle.

[0062] As a specific embodiment of a fastener anti-falling and parallel wire clamp provided by the present invention, please refer to Figure 2 , the first clamping member 13 and the second clamping member 14 are connected by a connecting section 1. The first clamping member 13, the second clamping member 14, and the connecting section 1 are an integral structure. A plurality of parallel wire grooves 2 are provided on the connecting section 1, and the wire grooves 2 are used for placing wires.

[0063] In this embodiment, the first clamping member 13 and the second clamping member 14 are connected by a connecting section 1. The first clamping member 13, the second clamping member 14, and the connecting section 1 are an integral structure. The integral structure composed of the first clamping member 13, the second clamping member 14, and the connecting section 1 can be manufactured by casting, forging, or other one-piece forming processes. And the manufactured integral structure has elasticity. When the bolt 4 and the nut 3 are tightened, because the integral structure composed of the first clamping member 13, the second clamping member 14, and the connecting section 1 has elasticity, the wires can be better clamped, ensuring the stability of wire clamping.

[0064] In this embodiment, a plurality of parallel wire grooves 2 are provided on the connecting section 1. The wire grooves 2 are used for placing wires, and the shape of the wire grooves 2 is consistent with the shape of the wires.

[0065] In this embodiment, two wire grooves 2 are provided on the connecting section 1, and the length directions of the two wire grooves 2 are parallel.

[0066] In this embodiment, the inner wall of the wire groove 2 is corrugated to prevent the wires from sliding.

[0067] As a specific embodiment of a fastener anti-falling and parallel wire clamp provided by the present invention, please refer to Figures 1 to 3 , the first through hole 6 is one of a rectangular hole, an oblong hole, an elliptical hole, a rhombic hole, or a trapezoidal hole, and the shape of the nut of the bolt 4 is consistent with the shape of the first through hole 6.

[0068] In this embodiment, the shape of the first through hole 6 is consistent with the shape of the nut of the bolt 4, which is convenient for the operator to have a reference during installation and can quickly find the insertion position of the first connecting portion and the second connecting portion. At the same time, the size of the first through hole 6 is smaller than the size of the nut of the bolt 4.

[0069] As a specific embodiment of the anti-falling and through wire clamp for fasteners provided by the present invention, please refer to Figures 1 to 3 , the first mounting hole 6 is a rectangular hole. When the first connecting portion and the second connecting portion are inserted, the length direction of the nut is perpendicular to the length direction of the first mounting hole 6.

[0070] In this embodiment, the first mounting hole 6 is a rectangular hole, and the nut of the bolt 4 is a cuboid. When the first connecting portion and the second connecting portion are clamped, the length direction of the nut is perpendicular to the length direction of the first long hole. Therefore, when installing the bolt 4, according to the shape of the first mounting hole 6 and the shape of the nut, the length direction of the nut is inserted parallel to the length direction of the first mounting hole 6. When clamping is required, the nut is rotated to a position where the length direction is perpendicular to the length direction of the first mounting hole 6, and the clamping of the first connecting portion and the second connecting portion can be successfully realized. That is to say, when the first connecting portion and the second connecting portion are clamped, the nut and the first mounting hole 6 are in a "+" shape when viewed from above.

[0071] In this embodiment, when the operator conducts high-altitude operations with a pre-installed anti-falling and through wire clamp for fasteners, the high-altitude operation steps of the operator are as follows:

[0072] First step, the wire can be inserted into the placement space from both sides of the first clamping member 13 and the second clamping member 14;

[0073] Second step, after the wire is placed or connected, first adjust the length direction of the nut to be parallel to the first mounting hole 6, and then rotate the bolt 4 by 90 degrees so that the first connecting portion and the second connecting portion are inserted, thereby restricting the rotational freedom of the bolt 4;

[0074] Third step, tighten the nut 3, and the nut 3 presses the second clamping member 14 through the flat washer to realize clamping of the wire.

[0075] In this embodiment, by controlling the shapes of the first mounting hole 6 and the nut, and cooperating with the positions of the groove 9 and the rib 5, it is ensured that when the groove 9 and the rib 5 are inserted and matched, the length direction of the first mounting hole 6 is perpendicular to the length direction of the nut, so that the operator can quickly find the insertion position of the groove 9 and the rib 5, and the high-altitude operation time can be effectively shortened.

[0076] As a specific embodiment of the anti-falling and through wire clamp for fasteners provided by the present invention, please refer to Figure 2 , two wire grooves 2 are provided, the cross-section of the connecting section 1 is ω-shaped, the first clamping member 13 is a first end plate, the second clamping member 14 is a second end plate, and the first end plate and the second end plate are respectively arranged at both ends of the connecting section 1.

[0077] In this embodiment, the cross-section of the connecting section 1 is omega-shaped, and the two arc-shaped grooves on the connecting section 1 with an omega-shaped cross-section are the two wire grooves 2. The wire grooves 2 can pre-position the wires, and the bolts 4 passing through the first through-hole and the second through-hole can prevent the wires from coming out from the opening direction of the omega-shaped connecting section 1. Therefore, when working at height and tightening the nuts 3, there is no need to use one hand to fix the wires, which facilitates the operators to work quickly.

[0078] In this embodiment, the first mounting hole 6 is a rectangular hole, and the nut of the bolt 4 is a cuboid. When the first connecting portion and the second connecting portion are clamped, the length direction of the nut is perpendicular to the length direction of the first long hole. The length direction of the first mounting hole 6 is parallel to the length direction of the first end plate, so that the operator can more conveniently observe whether the length direction of the nut is perpendicular to the length direction of the first mounting hole 6 and can more quickly find the insertion position of the first connecting portion and the second connecting portion.

[0079] As a specific embodiment of a fastener anti-falling and wire-passing clamp provided by the present invention, please refer to Figures 2 to 5 , a clamping groove 7 is provided on the side wall of the convex rib 5, a clamping head 10 is provided in the groove 9, and the clamping head 10 is clamped with the clamping groove 7. The clamping head 10 and the clamping groove 7 are used to limit the axial movement of the bolt 4 along its own axis.

[0080] In the previous embodiment, after pre-installing a fastener anti-falling and wire-passing clamp, in order to facilitate the subsequent insertion of the wires, the nut 3 cannot be tightened. This enables the bolt 4 to move along the axis direction of the bolt 4 before the first connecting portion and the second connecting portion are clamped, and the bolt 4 can still rotate. Therefore, when working at height, it is still necessary to rotate the bolt 4 for clamping alignment, which increases the duration of working at height.

[0081] In this embodiment, a clamping groove 7 is provided on the side wall of the convex rib 5, and a clamping head 10 is provided in the groove 9. The clamping head 10 is clamped with the clamping groove 7. When pre-installing a fastener anti-falling and wire-passing clamp, the first connecting portion and the second connecting portion are clamped, and at the same time, the clamping head 10 is clamped with the clamping groove 7, so as to limit the rotational freedom of the bolt 4 along its axis and the movement freedom along its own axis, ensuring the fixation of the bolt 4. Therefore, when working at height, after the wires are inserted into a fastener anti-falling and wire-passing clamp, it is only necessary to tighten the nut 3, making the working at height more efficient.

[0082] As a specific embodiment of a fastener anti-falling and wire-passing clamp provided by the present invention, please refer to Figures 2 to 5 , a receiving cavity is provided on the side wall of the groove 9, a spring 11 and a clamping head 10 are provided in the receiving cavity, the clamping head 10 is slidably arranged in the receiving cavity, one end of the spring 11 is connected to the clamping head 10, and the other end is connected to the cavity wall of the receiving cavity. The spring 11 is used to push the clamping head 10 to insert into the clamping groove 7.

[0083] In this embodiment, a receiving cavity is provided on the side wall of the groove 9. A spring 11 and a clamping head 10 are provided in the receiving cavity. The clamping head 10 is slidably disposed in the receiving cavity. One end of the spring 11 is connected to the clamping head 10, and the other end is connected to the wall of the receiving cavity. During the clamping process of the first connecting portion and the second connecting portion, the clamping head 10 retracts into the receiving cavity under the block of the side wall of the rib 5. At this time, the spring 11 is compressed by force. When the first connecting portion and the second connecting portion are clamped, the clamping head 10 is aligned with the clamping groove 7. At this time, the clamping head 10 extends into the clamping groove 7 under the elastic force of the spring 11, completing the installation and fixation of the bolt 4. If the bolt 4 needs to be disassembled, the nut 3 is removed, and then the bolt 4 is pulled out by an external force. Under the external force, the clamping head 10 retracts into the receiving cavity, so that the bolt 4 can be pulled out.

[0084] As a specific embodiment of a fastener anti-falling and wire-passing clamp provided by the present invention, please refer to Figures 2 to 5 , along the depth direction of the groove 9, inclined surfaces 12 are provided at both the upper end and the lower end of the clamping head 10.

[0085] In this embodiment, along the depth direction of the groove 9, inclined surfaces 12 are provided at both the upper end and the lower end of the clamping head 10. When the bolt 4 needs to be pulled out, the inclined surface 12 at the upper end contacts the edge of the clamping groove 7. When the bolt 4 is pulled by an external force, a force directed radially towards the bolt 4 is decomposed from the tensile force along the axis direction of the bolt 4 on the inclined surface 12 at the upper end. This radial force pushes the clamping head 10 to retract into the receiving cavity. When assembling the bolt 4, the principle of the inclined surface 12 at the lower end is the same as that of the inclined surface 12 at the upper end. The provision of inclined surfaces 12 at both the upper end and the lower end of the clamping head 10 facilitates the disassembly and assembly of the bolt 4.

[0086] The above are only the preferred embodiments of the present invention and are not intended to limit the present invention. Any modifications, equivalent replacements, and improvements made within the spirit and principle of the present invention shall be included in the protection scope of the present invention.
