[0052] See also Figure 1 and Figure 2 The present invention provides a wire clamp, comprising an upper clamping rod 1, a lower clamping rod 2, an upper toothed disc 3, a lower toothed disc 4, and a push rod 5. The push rod 5 is axially oriented in the vertical direction. The upper clamping rod 1, the upper toothed disc 3, the lower toothed disc 2, and the lower clamping rod 4 are rotatably sleeved on the push rod 5 in sequence from top to bottom. The upper toothed disc 3 is fixedly connected to the upper clamping rod 1; the lower toothed disc 3 is fixedly connected to the lower clamping rod 2. The push rod 5 is slidably connected to the upper clamping rod 1, the upper toothed disc 3, the lower toothed disc 4, and the lower clamping rod 2 in the vertical direction.

[0053] Among them, the push rod 5 can be connected to the upper clamping rod 1, the upper gear plate 3, the lower gear plate 2 and the lower clamping rod 4 through a linear bearing and a rotating bearing, that is, the push rod 5 is sleeved on the linear bearing, and the linear bearing is sleeved on the rotating bearing, so that the push rod 5 can slide in the vertical direction while the upper clamping rod 1, the lower clamping rod 2, the upper gear plate 3 and the lower gear plate 4 can rotate around the push rod 5.

[0054] The bottom of the upper gear disc 3 is provided with inclined upper blade teeth 31; the top of the lower gear disc 4 is provided with lower blade teeth 41 with the same inclination direction as the upper blade teeth 31. In the locked state, the upper blade teeth 31 and the lower blade teeth 41 are connected in a one-way meshing manner, and the upper gear disc 3 and the lower gear disc 4 form a one-way meshing structure, which restricts the upper clamping rod 1 and the lower clamping rod 2 from rotating in the direction away from each other; in the unlocked state, the upper blade teeth 31 are separated from the lower blade teeth 41; the push rod 5 is used to push the lower clamping rod 2 downward when sliding downward, so that the upper blade teeth 31 are separated from the lower blade teeth 41 and enter the unlocked state. Among them, the one-way meshing structure formed by the upper gear disc 3 and the lower gear disc 4 means that the upper gear disc 3 and the lower gear disc 4 can only mesh and transmit in one direction, and relative sliding will occur in the other direction and meshing and transmission cannot be achieved.

[0055] Specifically, see Figures 3 to 5 In this embodiment, an angle is formed between the upper clamping rod 1 and the lower clamping rod 2 when viewed from above. When the upper clamping rod 1 rotates counterclockwise relative to the lower clamping rod 2 when viewed from above, the angle increases. When the upper clamping rod 1 rotates clockwise relative to the lower clamping rod 2, the angle decreases, allowing the upper clamping rod 1 and the lower clamping rod 2 to clamp the wire tightly. Furthermore, in this embodiment, both the upper blade teeth 31 and the lower blade teeth 41 are inclined counterclockwise from top to bottom when viewed from above.

[0056] In the locked state, when the upper clamping rod 1 rotates counterclockwise relative to the lower clamping rod 2 in the top view, that is, when the upper clamping rod 1 and the lower clamping rod 2 rotate away from each other, the upper toothed disc 3 will drive the meshed lower toothed disc 4 to rotate synchronously, so that the lower clamping rod 2 rotates synchronously with the upper clamping rod 1, thereby preventing the angle from increasing. When the upper clamping rod 1 rotates clockwise relative to the lower clamping rod 2 in the top view, that is, when the upper clamping rod 1 and the lower clamping rod 2 rotate toward each other, the inclined upper teeth 31 and the lower teeth 41 slide relative to each other, so that the upper toothed disc 3 cannot drive the lower toothed disc 4 to rotate, thereby allowing the upper clamping rod 1 and the lower clamping rod 2 to undergo relative displacement with a smaller angle. That is, in the locked state, the angle between the upper clamping rod 1 and the lower 2 can only decrease but not increase, thereby achieving the purpose of clamping the wire.

[0057] In the unlocked state, the upper toothed disc 3 is separated from the lower toothed disc 4, allowing the upper clamping rod 1 and the lower clamping rod 2 to rotate freely, thereby increasing the angle between them and allowing the wire to be removed. Furthermore, by pressing the push rod 5, the lower toothed disc 4 on the lower clamping rod 2 is pushed downward. Compared to existing wire clamps that require the laborious pushing of a pull ring, this method is much simpler to operate and can improve the safety of aerial work.

[0058] It should be noted that in the locked state, a margin gap is formed between the upper blade teeth 31 and the lower blade teeth 41, making it easier for the upper blade teeth 31 and the lower blade teeth 41 to slide relative to each other when the upper clamping rod 1 and the lower clamping rod 2 rotate relative to each other in the direction of increasing the included angle. At the same time, the upper blade teeth 31 and the lower blade teeth 41 can be made of an elastic material, so that they have a certain degree of elasticity and can deform when they abut.

[0059] When using existing wire clamps, after they have locked onto the wire, the operator needs to hold the clamp body with one hand and push the pull ring with the other hand, which is laborious and dangerous when working at height. To release the clamp, the operator only needs to press the push rod 5 to rotate the upper clamping rod 1 and the lower clamping rod 2 in the direction of increasing the included angle, saving time and effort and reducing the danger of the operation.

[0060] Other embodiments further include a sleeve 6 and a torsion spring 7; the sleeve 6 is fixed to the upper clamping rod 1; the push rod 5 is sleeved within the sleeve 6, rotatably connected to the sleeve 6 and vertically slidably connected to the sleeve 6; the ends of the torsion spring 7 are respectively fixedly connected to the push rod 5 and the sleeve 6; the push rod 5 and the lower clamping rod 2 are synchronously rotated in the direction of increasing the included angle. Similarly, the push rod 5 can be connected to the sleeve 6 via a linear bearing sleeved with a rotating bearing.

[0061] Specifically, the lower clamping rod 2 is a stationary reference system. When the upper clamping rod 1 rotates in the direction of decreasing the angle, the torsion spring 7 is driven by the rotation of the sleeve 6 and begins to store energy. The push rod 5 is connected to the lower clamping rod 2 to rotate synchronously in the direction of increasing the angle, so the push rod 5 cannot rotate in the direction of increasing the angle, so that in the locked state, the angle cannot increase and the torsion spring 7 will remain in the energy storage state. When the push rod 5 is pressed to enter the unlocked state, the potential energy release of the torsion spring 7 will drive the upper clamping rod 1 and the lower clamping rod 2 to automatically rotate relative to each other in the direction of increasing the angle, so that the wire can be automatically loosened after the push rod 5 is pressed, increasing the convenience of the operation.

[0062] In one embodiment, a protrusion 51 is provided on the side of the push rod 5; a guide groove 21 is provided vertically on the lower clamping rod 2; the protrusion 51 can slide into the guide groove 21, so that the push rod 5 and the lower clamping rod 2 are synchronously rotated and connected. In addition, the push rod 5 can be made of an insulating material to improve the safety of clamping the wire.

[0063] That is, in this embodiment, the push rod 5 and the lower clamping rod 2 are connected to rotate synchronously in the direction of increasing the included angle through the cooperation between the protrusion 51 and the guide groove 21 .

[0064] In another embodiment, a one-way bearing (not shown) can be provided on the lower clamping rod 2. The one-way bearing can be disposed in the guide groove 21, and the push rod 5 is engaged in the one-way bearing. The one-way bearing 5 allows the push rod 5 to rotate relative to the lower clamping rod 2 in a direction in which the included angle decreases, while in a direction in which the included angle increases, the push rod 5 rotates synchronously with the lower clamping rod 2. At the same time, the one-way bearing can serve as a support for the bottom of the push rod 5, thereby balancing the torque and improving the stability of the overall transmission structure.

[0065] In a more specific embodiment, an elastic nib lock 8 may also be included; the push rod 5 is connected to the sleeve 6 via the elastic nib lock 8. Specifically, the elastic nib lock 8 is a conventional elastic locking structure used in automatic ballpoint pens. When pressed for the first time, the nib of the automatic ballpoint pen extends and remains extended; when pressed for the second time, the nib retracts and remains retracted. Similarly, the elastic nib lock 8 allows the push rod 5 to remain depressed after a single press, thereby maintaining the unlocked state of the entire device. A further press causes the push rod 5 to retract under elastic force, maintaining the locked state of the entire device.

[0066] In other embodiments, see Figure 1 , also includes two clamping bars 9; the two clamping bars 9 are respectively connected to the upper clamping rod 1 and the lower clamping rod 2 for clamping the wire.

[0067] Specifically, two clamping bars 9 can be arranged below the upper clamping rod 1 and the lower clamping rod 2, and can be brought closer to each other to clamp the wire when the angle becomes smaller. Among them, the two clamping bars 9 can be provided with anti-slip grooves on the side facing each other to better clamp the wire.

[0068] Furthermore, the clamping bar 9 is a telescopic structure and can be rotatably connected to the upper clamping rod 1 and the lower clamping rod 2 at the same time; the two clamping bars 9 are arranged in parallel.

[0069] Specifically, the upper clamping rod 1 and the lower clamping rod 2 cross each other. Each clamping bar 9 is connected to the upper clamping rod 1 and the lower clamping rod 2 at the same time. When the upper clamping rod 1 and the lower clamping rod 2 rotate, the clamping bar 9 can follow the rotation of the upper clamping rod 1 and the lower clamping rod 2 and extend and retract.

[0070] In this embodiment, the clamping bar 9 is formed by connecting a plurality of sub-clamping bars end to end; the sub-clamping bars are provided with sliders and slide rails. The sliders can slide into the slide rails of adjacent sub-clamping bars to achieve the overall retractability of the clamping bar 9.

[0071] Furthermore, it also includes a limit rod 10; a slide groove 101 with closed ends is provided on the limit rod 10; the two clamping bars 9 are rotatably connected to the upper clamping bar 1 and the lower clamping bar 2 through a rotating column 91; the rotating column 91 can slide into the slide groove 101; the length direction of the limit rod 10 is perpendicular to the length direction of the clamping bar 9.

[0072] Specifically, the rotating column 91 vertically penetrates the upper clamping rod 1 and the lower clamping rod 2. The limiting rod 10 is sleeved on the rotating column 91 through the sliding groove 101, thereby limiting the maximum opening between the two clamping bars 9.

[0073] Among them, the limit rod 10 can be set above the two clamping bars 9. At the same time, the two rotating columns 91 whose connecting line is perpendicular to the length direction of the clamping bar 9 can pass through the bottom of the clamping bar 9, so that the bottom of the two rotating columns 91 extends downward relative to the clamping bar 9 to form two extension platforms. The two extension platforms can be connected with anti-drop buckles; specifically, the anti-drop buckle can be fixedly connected to one extension platform at one end and snap-connected to the other extension platform at the other end, so that after the two clamping bars 9 clamp the wire, the anti-drop buckle can connect the two extension platforms, so that after pressing the push rod 5 to release the two clamping bars 9, the entire device will not fall directly from the wire, reducing the risk of the entire device falling during high-altitude operations and improving the safety of the operation.

[0074] Furthermore, the device includes multiple connecting bars 11. These connecting bars 11, the upper clamping bar 1, and the lower clamping bar 2 form a double-prism telescopic structure. The clamping bar 9 extends in the same direction as the double-prism telescopic structure. Both ends of the clamping bar 9 can be rotatably connected to the connecting bars 11, making the overall structure more stable during transmission.

[0075] Furthermore, the hook 12 is provided with an elastic automatic locking block 13 at its opening. The hook 12 is rotatably mounted on the double-prism telescopic structure, and may be located at one end of the double-prism telescopic structure. In actual use, after hooking an object to the hook 12, the other end of the double-prism telescopic structure can be pulled to extend the double-prism telescopic structure, thereby tightening the two clamping bars 9.

[0076] Specifically, the elastic automatic locking block 13 can be composed of a baffle and a spring, and one end of the baffle can be rotatably connected to the hook, and the other end is inclined outward relative to the hook, so that when the hook is hooked, it can be rotated inward to allow the object to enter the hook, and after hooking, it is automatically reset by the elastic force of the spring, making it difficult for the hook to detach from the object.

[0077] The above are only preferred embodiments of the present application and are not intended to limit the present invention. Although the present application has been described in detail with reference to examples, those skilled in the art can still modify the technical solutions described in the aforementioned examples or make equivalent replacements for some of the technical features therein.
