Technical Field

[0001] This application relates to the field of wire clamping device technology, and more particularly to a wire clamp. Background Technology

[0002] In power engineering construction or routine power grid maintenance, wire clamps are frequently used for tightening, adjusting, and loosening wires. Traditional wire clamps typically consist of a pull ring and a lever. When the pull ring rotates, it uses a lever principle to clamp and lock the conductor. To remove the wire clamp, the worker needs to hold the clamp body with one hand and push the pull ring with the other, making the operation quite strenuous and posing a certain degree of danger when working at heights. Summary of the Invention

[0024] In the locked state, the upper and lower gears are engaged in a one-way connection, restricting the upper and lower clamping rods from rotating in a direction away from each other;

[0025] The inner slide bar is used to slide downwards during the locking operation, causing the horizontal cone rod to slide below the upper cone so that the horizontal cone rod and the upper cone are locked together.

[0026] Furthermore, it also includes sleeves and torsion springs;

[0027] The sleeve is fixed to the upper clamping rod;

[0028] The outer fixed rod is sleeved inside the sleeve and is rotatably connected to the sleeve.

[0029] The push rod and the sleeve are respectively fixedly connected to both ends of the torsion spring;

[0030] The lower clamp and the upper clamp form an angle on their projections along the vertical direction;

[0031] The outer fixed rod and the lower clamp rod are synchronously connected and rotate in the direction of increasing included angle.

[0032] Furthermore, a protrusion is provided on the side of the push rod;

[0033] The lower clamping rod is provided with a guide groove along the vertical direction;

The push rod is slidably connected vertically to the upper clamping rod, upper gear plate, lower gear plate, and lower clamping rod. In the locked state, the upper and lower blades are engaged in a one-way engagement, and the upper and lower gear plates form a one-way engagement structure, restricting the upper and lower clamping rods from rotating away from each other. In the unlocked state, the upper and lower blades are separated. The push rod is used to push the lower clamping rod downwards when sliding downwards, causing the upper and lower blades to separate and enter the unlocked state. Through the cooperation of the upper and lower gear plates, when the push rod is pressed to enter the unlocked state, the upper and lower blades separate, allowing the upper and lower clamping rods to rotate away from each other and thus engage the clamping state of the wire clamp. Compared with existing wire clamps, this is more convenient and less strenuous to operate. Attached Figure Description

Obviously, the described embodiments are only some, not all, of the embodiments of this application. Based on the embodiments of this application, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection claimed in this application.

[0063] In the description of the embodiments of this application, it should be noted that, unless otherwise explicitly specified and limited, the terms "installation," "connection," and "linking" should be interpreted broadly. For example, they can refer to a fixed connection, a replaceable connection, or an integral connection; they can refer to a mechanical connection or an electrical connection; they can refer to a direct connection or an indirect connection through an intermediate medium; and they can refer to the internal connection of two components. Those skilled in the art can understand the specific meaning of the above terms in the embodiments of this application based on the specific circumstances.

[0064] Please see Figures 1 to 3 This application provides a wire clamp comprising: an upper clamping rod 1, a lower clamping rod 2, an upper geared disc 3, a lower geared disc 4, and a push rod 5; with the axis of the push rod 5 as the vertical direction, in this embodiment, the push rod 5 is vertically arranged; the push rod 5 includes: an outer fixed rod 51, an inner sliding rod 52, a vertical spring 53, a horizontal cone rod 54, a horizontal spring 55, a locking rod 56, an upper cone 57, and a lower cone 58; the upper clamping rod 1, the upper geared disc 3, the lower geared disc 4, and the lower clamping rod 2 are rotatably sleeved on the outer fixed rod 51 from top to bottom. The upper geared disc 3 is fixedly connected to the upper clamping rod 4, and both the upper geared disc 3 and the upper clamping rod 1 are axially fixedly connected to the outer fixed rod 51; the lower geared disc 4 is fixedly connected to the lower clamping rod 2, and both the lower geared disc 4 and the lower clamping rod 2 are axially slidably connected to the outer fixed rod 51.

[0065] That is, the outer fixed rod 51 can rotate relative to the upper clamping rod 1 and the lower clamping rod 2, while the outer fixed rod 51 and the upper clamping rod 1 cannot move relative to each other in the vertical direction, but the outer fixed rod 51 and the lower clamping rod 2 can move relative to each other in the vertical direction. Accordingly, the lower clamping rod 2 can be provided with a sliding hole 21 for the outer fixed rod 51 to be slidably inserted.

[0066] The bottom of the upper gear plate 3 is provided with inclined upper cutting teeth 31; the top of the lower gear plate 4 is provided with lower cutting teeth 41 in the same inclination direction as the upper cutting teeth 31. The inner slide rod 52 is vertically slidable within the outer fixed rod 51; the top and bottom of the vertical spring 53 are respectively fixedly connected to the bottom of the inner slide rod 52 and the outer fixed rod 51; the locking rod 56 is located below the inner slide rod 52 and is fixedly connected to the lower gear plate 4; the lower cone 58 is slidably mounted on the locking rod 56; the upper cone 57 is fixed on the locking rod 56 and located above the lower cone 58; the normal direction of the cone surface of the upper cone 57 is inclined upwards; the normal direction of the cone surface of the lower cone 58 is inclined downwards; the horizontal cone rod 54 is slidably mounted on the inner slide rod 52 in the horizontal direction; the two ends of the horizontal spring 55 are respectively fixedly connected to the horizontal cone rod 54 and the inner slide rod 52; the end of the horizontal cone rod 54 near the locking rod 56 is provided with an inclined cone surface for cooperating with the inclined wedge of the upper and lower cones; the normal direction of the inclined cone surface is inclined downwards.

[0067] Specifically, the outer fixed rod 51 can be hollow inside, forming a hollow groove 511 for mounting the inner sliding rod 52 and the vertical spring 53. The inner sliding rod 52 is provided with a corresponding mounting groove 521 for mounting the horizontal tapered rod 54. At the same time, in order to allow the bottom of the vertical spring 53 to be mounted, the outer fixed rod 51 can be provided with an inner boss 512 in the hollow groove 511 for the vertical spring 53 to abut against.

[0068] In the unlocked state, the horizontal cone rod 54 is located above the upper cone 57. At this time, the upper gear plate 3 and the lower gear plate 4 are separated, so the mutual rotation between the upper clamping rod 1 and the lower clamping rod 2 will not cause interference.

[0069] In the locked state, the horizontal cone rod 54 is located between the upper cone 57 and the lower cone 58. At this time, the upper gear plate 3 and the lower gear plate 4 are in a one-way meshing state, so the upper clamping rod 1 and the lower clamping rod 2 will interfere with each other when they rotate.

[0070] When locking from the unlocked state, the inner slide bar 52 is pushed downwards, causing the horizontal cone bar 54 to move downwards. During this process, the upper cone 57 pushes the horizontal cone bar 54 horizontally outwards until it can pass under the upper cone 57. Since the bottom surface of the upper cone 57 cannot engage with the inclined cone surface of the horizontal cone bar 54, the horizontal cone bar 54 and the upper cone 57 are locked in the upward direction. Then, driven by the spring force of the vertical spring 53, the inner slide bar 52 moves upwards, causing the horizontal cone bar 54 to move upwards synchronously with the upper cone 57, which in turn causes the locking bar 56 and the lower gear plate 4 to move upwards synchronously. Correspondingly, the outer fixed bar 51 can be provided with an upper limit member so that the inner slide bar 52, which is resetting upwards, stops just when the lower gear plate 4 engages with the upper gear plate 3, thus entering the locked state.

[0071] When unlocking from the locked state, the inner slide bar 52 is pushed downwards, causing the horizontal cone bar 54 to move downwards. During this process, the lower cone 58 pushes the horizontal cone bar 54 horizontally outwards until it can pass under the lower cone 58. Then, driven by the spring force of the vertical spring 53, the inner slide bar 53 moves the horizontal cone bar 54 upwards. In this process, the horizontal cone bar 54 simultaneously moves the lower cone 58 upwards until it abuts against the upper cone 57. Then, the downward-sloping cone surface of the lower cone 58 slides into contact with the horizontal cone bar 54, pushing it horizontally outwards until it can pass under the lower cone 58 and then the upper cone 57. This causes the horizontal cone bar 54 to return to above the upper cone 54, and the unlocked locking bar 56 moves downwards until the lower gear plate 4 separates from the upper gear plate 3, entering the unlocked state.

[0072] Correspondingly, a lower limit component can be provided inside the outer fixed rod 51, so that the locking rod 56, lower gear plate 4 and lower clamping rod 2, which slide downward after unlocking, will not slip off the outer fixed rod 51.

[0073] It should be noted that in the locked state, the upper cutting tooth 31 and the lower cutting tooth 41 are engaged in a one-way connection, and the upper gear plate 3 and the lower gear plate 4 form a one-way meshing structure, restricting the upper clamping rod 1 and the lower clamping rod 2 from rotating in opposite directions. In the unlocked state, the upper cutting tooth 31 and the lower cutting tooth 41 are separated, and the upper clamping rod 1 and the lower clamping rod 2 can rotate relative to each other in any direction. The one-way meshing structure of the upper gear plate 3 and the lower gear plate 4 means that the upper gear plate 3 and the lower gear plate 4 can only mesh and transmit power in one direction; in the other direction, relative sliding will occur, and meshing and transmission will be impossible.

[0074] For more specific details, please refer to Figures 1 to 6In this embodiment, an angle is formed between the upper clamping rod 1 and the lower clamping rod 2 in the top view. In the top view, the angle increases when the upper clamping rod 1 rotates counterclockwise relative to the lower clamping rod 2; the angle decreases when the upper clamping rod 1 rotates clockwise relative to the lower clamping rod 2, thus allowing the upper clamping rod 1 and the lower clamping rod 2 to clamp the wire tightly. Simultaneously, in this embodiment, both the upper cutting tooth 31 and the lower cutting tooth 41 are inclined counterclockwise from top to bottom in the top view.

[0075] In the locked state, from a top-down view, when the upper clamping rod 1 rotates counterclockwise relative to the lower clamping rod 2 (i.e., when the upper clamping rod 1 and the lower clamping rod 2 rotate away from each other), the upper gear 3 drives the meshing lower gear 4 to rotate synchronously, causing the lower clamping rod 2 to rotate synchronously with the upper clamping rod 1, thus preventing the included angle from increasing. From a top-down view, when the upper clamping rod 1 rotates clockwise relative to the lower clamping rod 2 (i.e., when the upper clamping rod 1 and the lower clamping rod 2 rotate towards each other), the inclined upper cutting teeth 31 and lower cutting teeth 41 slide relative to each other, preventing the upper gear 3 from driving the lower gear 4 to rotate, thus allowing the upper clamping rod 1 and the lower clamping rod 2 to undergo a relative displacement with a smaller included angle. In other words, in the locked state, the included angle between the upper clamping rod 1 and the lower clamping rod 2 can only decrease and cannot increase, thus achieving the goal of clamping the wire tightly.

[0076] In the unlocked state, the upper gear plate 3 and the lower gear plate 4 are separated. At this time, the upper clamping rod 1 and the lower clamping rod 2 can rotate freely, thereby increasing the included angle and allowing the wire to be removed. Furthermore, by pressing the inner slide rod 52, the lower gear plate 4 on the lower clamping rod 2 can be moved downwards. Compared with the existing wire clamps that require force to push the pull ring, the operation is much simpler and can improve the safety of high-altitude operations.

[0077] It should be noted that in the locked state, a clearance exists between the upper cutting tooth 31 and the lower cutting tooth 41, making it easier for the upper cutting tooth 31 and the lower cutting tooth 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 angle. At the same time, the upper cutting tooth 31 and the lower cutting tooth 41 can be made of elastic material, so that they have a certain degree of elasticity and can deform when they come into contact.

[0078] Existing wire clamps require workers to hold the clamp body with one hand and push the pull ring with the other after it has locked onto the wire. This is strenuous and poses a certain danger when working at heights. The wire clamp in this solution can switch between locked and unlocked states by pressing the inner slide bar 52. To release the clamp, simply press the inner slide bar 52 to unlock it, which will then rotate the upper clamp 1 and lower clamp 2 in the direction of increasing angle. This saves time and effort and reduces the danger of the operation.

[0079] In other embodiments, a sleeve 6 and a torsion spring 7 are also included; the sleeve 6 is fixed on the upper clamping rod 1; the outer fixed rod 51 is sleeved inside the sleeve 6 and is rotatably connected to the sleeve 6; the two ends of the torsion spring 7 are respectively fixedly connected to the push rod 5 and the sleeve 6; the outer fixed rod 51 and the lower clamping rod 2 are synchronously rotatably connected in the direction of increasing included angle.

[0080] Specifically, the lower clamping rod 2 is a stationary reference frame. When the upper clamping rod 1 rotates in the direction of decreasing angle, the torsion spring 7 begins to store energy due to the rotation of the sleeve 6. The outer fixed rod 51 and the lower clamping rod 2 are synchronously connected and rotate in the direction of increasing angle. Therefore, the outer fixed rod 51 cannot rotate in the direction of increasing angle, so that in the locked state, the angle cannot increase, and the torsion spring 7 will remain in the stored energy state. After pressing the inner slide rod 52 to enter the unlocked state, the potential energy released by the torsion spring 7 will cause the upper clamping rod 1 and the lower clamping rod 2 to automatically rotate relative to each other in the direction of increasing angle, so that pressing the inner slide rod 52 will automatically release the wire, increasing the convenience of operation.

[0081] In one embodiment, the outer fixed rod 51 and the lower clamping rod 2 are synchronously connected in the direction of increasing angle by installing a one-way bearing (not shown in the figure) on the lower clamping rod 2. The one-way bearing is installed on a linear bearing, allowing the one-way bearing to follow the relative displacement between the outer fixed rod 51 and the lower clamping rod 2. The one-way bearing 5 is installed in the sliding hole 21, and the outer fixed rod 51 is inserted into the one-way bearing. Through the one-way bearing 5, the outer fixed rod 51 can rotate relative to the lower clamping rod 2 in the direction of decreasing angle, while in the direction of increasing angle, the outer fixed rod 51 will rotate synchronously with the lower clamping rod 2. Simultaneously, the one-way bearing provides support for the bottom of the outer fixed rod 51, thereby balancing the torque and improving the overall structural transmission stability. In other embodiments, an external protrusion can be provided on the outer fixed rod 51 to restrict the outer fixed rod 51 from rotating relative to the lower clamping rod 2, specifically ensuring that the outer fixed rod 51 and the lower clamping rod 2 are synchronously connected in the direction of increasing angle.

[0082] In other embodiments, please refer to Figure 1 It 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, and are used to clamp the wire.

[0083] Specifically, two clamping bars 9 can be positioned below the upper clamping rod 1 and the lower clamping rod 2, and can move closer together to clamp the wire when the angle between them decreases. The opposing sides of the two clamping bars 9 can be provided with anti-slip textures for better wire clamping.

[0084] Furthermore, the clamping bar 9 is a telescopic structure and can rotatably connect the upper clamping rod 1 and the lower clamping rod 2; the two clamping bars 9 are arranged in parallel.

[0085] Specifically, the upper clamping rod 1 and the lower clamping rod 2 intersect each other. Each clamping bar 9 is simultaneously connected to both the upper clamping rod 1 and the lower clamping rod 2. When the upper clamping rod 1 and the lower clamping rod 2 rotate, the clamping bar 9 can extend and retract in tandem with the rotation of the upper clamping rod 1 and the lower clamping rod 2.

[0086] In this embodiment, the clamping bar 9 is formed by splicing together multiple sub-clamping bars end to end; each sub-clamping bar is equipped with a slider and a slide rail. The slider can slide into the slide rail of an adjacent sub-clamping bar, thus enabling the clamping bar 9 to be retractable as a whole.

[0087] Furthermore, it also includes a limiting rod 10; the limiting rod 10 is provided with a sliding groove 101 closed at both ends; both clamping bars 9 are rotatably connected to the upper clamping rod 1 and the lower clamping rod 2 through a rotating column 91; the rotating column 91 can slide into the sliding groove 101; the length direction of the limiting rod 10 is perpendicular to the length direction of the clamping bar 9.

[0088] Specifically, the rotating column 91 passes vertically through 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.

[0089] The limiting rod 10 can be positioned above the two clamping bars 9. Simultaneously, two rotating posts 91, whose connecting line is perpendicular to the length of the clamping bars 9, can pass through the bottom of the clamping bars 9, causing the bottoms of these two rotating posts 91 to extend downwards relative to the clamping bars 9, forming two extension platforms. Anti-drop buckles can be connected to the two extension platforms; specifically, one end of the anti-drop buckle can be fixedly connected to one extension platform, and the other end can be snapped into place with the other extension platform. Thus, after the two clamping bars 9 clamp the wire, the anti-drop buckle connects to the two extension platforms, preventing the entire device from falling directly from the wire after the push rod 5 is pressed to release the two clamping bars 9. This reduces the risk of the entire device falling during high-altitude operations and improves operational safety.

[0090] Furthermore, it also includes multiple connecting bars 11; the multiple connecting bars 11, the upper clamping rod 1, and the lower clamping rod 2 form a double-prism telescopic structure; the telescopic direction of the clamping bar 9 is the same as the telescopic direction of 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.

[0091] Furthermore, it also includes a hook 12; an elastic automatic locking block 13 is provided on the opening of the hook 12; the hook 12 is rotatably mounted on the double-prism telescopic structure, and can be located at one end of the double-prism telescopic structure. In actual use, after the hook 12 is attached to an object, pulling the other end of the double-prism telescopic structure will cause the double-prism telescopic structure to extend, thereby causing the two clamping bars 9 to clamp.

[0092] Specifically, the elastic automatic locking block 13 can be composed of a baffle and a spring. One end of the baffle can be rotatably connected to the hook, and the other end is tilted outward relative to the hook. So when the hook is engaged, it can rotate inward to allow the object to enter the hook. After being engaged, it is pushed by the elastic force of the spring to automatically reset, making it difficult for the hook to detach from the object.

[0093] In a further improved embodiment, the lower cone 58 may be magnetic, for example, it may be an N pole. The bottom of the locking lever 56 has the opposite magnetic property to the lower cone 58, that is, an S pole. This arrangement allows the lower cone 58 to separate from the upper cone 57 by the magnetic attraction of the locking lever 56 when the entire device is not placed horizontally, thus preventing the lower cone 58 and the upper cone 57 from being in a close contact state when unlocked.

[0094] The above are merely preferred embodiments of this application and are not intended to limit the present invention. Although this application has been described in detail with reference to examples, those skilled in the art can still modify the technical solutions described in the foregoing examples or make equivalent substitutions for some of the technical features. However, any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of this application should be included within the protection scope of this application.
