The appearances of the phrase "in one embodiment" in various places in the specification are not necessarily all referring to the same embodiment, nor are separate or alternative embodiments mutually exclusive of other embodiments.

Referring to fig. 2 to 11, an embodiment of the present invention provides a push-pull type live-line lapping cable clamp, which is convenient for field installation and fixation, and reduces the difficulty and risk of live-line lapping operation.

The push-pull type live-wire lapping clip comprises a clip main body 100, a transmission case 200 fixed to the lower end of the clip main body 100, a sliding assembly 300 capable of sliding relative to the clip main body 100, and a non-return assembly 400 for preventing the sliding assembly 300 from loosening or sliding downward.

The wire clamp body 100 comprises a side plate 101 with a wire connecting part and a hook head 102 fixed at the upper end of the side plate 101, and the wire connecting part on the wire clamp body 100 of the invention can directly adopt the wire connecting part structure on the existing live-wire loading and unloading wire clamp, which is used for fixing the end of a drainage wire, and the description is omitted here.

The transmission box 200 is a box structure with a hollow interior, and is used for the sliding arrangement of the sliding assembly 300 in the transmission box and also for the installation and fixation of the check assembly 400. The transmission box 200 is fixed on the lower end of the side plate 101 and is opposite to the hook head 102. The interior of the transmission box 200 is provided with a chamber 201, and the upper end and the lower end of the transmission box 200 are respectively provided with a first through opening 202 which are opposite to each other.

The sliding assembly 300 includes a screw 301 passing through the first through hole 202, and a clamping block 302 disposed at an upper end of the screw 301 and opposite to the hook 102. The sliding assembly 300 can slide up and down in the first through opening 202 and clamp the main guide wire between the clamping block 302 and the hook head 102. Preferably, at the same time, the screw 301 is also capable of rotating itself in its circumferential direction.

The check assembly 400 includes a seesaw bar 401 hinged in the transmission case 200, a first pressing member 402 pressing on the seesaw bar 401, a pressing plate 403 hinged on an inner end of the seesaw bar 401, and a pulling member 404 having one end connected to a lower end of the pressing plate 403 and the other end passing around an outer end of the seesaw bar 401.

The tilting rod 401 is a rod-shaped structure, one end of the tilting rod is inclined upwards and faces the screw 301, the other end of the tilting rod extends out of the transmission box 200, and the tilting rod 401 can rotate in the transmission box 200.

The first pressing member 402 is a resilient piece fixed to the inner sidewall of the transmission case 200, and is capable of applying resilient pressure to the inner end of the seesaw bar 401 so that the upper end of the pressing plate 403 abuts against the outer sidewall of the screw 301.

The pressing plate 403 is preferably of an arc-shaped plate structure, and the upper end of the pressing plate is hinged to the inner end of the tilting rod 401 and can rotate relative to the tilting rod 401. Be provided with internal thread 403a on the medial surface of clamp plate 403, clamp plate 403 can laminate and press on the lateral wall of screw rod 301, and its internal thread 403a and the external screw thread 301a looks adaptation of screw rod 301, so have two effects: firstly, the internal thread 403a of the pressing plate 403 is meshed with the external thread 301a of the screw 301, which can be an obstacle to the up-and-down sliding stroke of the screw 301, so that when the pressing plate 403 is attached to the outer side wall of the screw 301, the sliding assembly 300 cannot slide up and down in the first through opening 202; second, the internal thread 403a of the pressing plate 403 also provides a matching structure for the rotation adjustment of the screw 301, so that the vertical position can be adjusted by the matching of the threads when the screw 301 is rotated.

Preferably, the inner end of the seesaw bar 401 is directed toward the outer surface of the screw 301, and has an upward component from the outside to the inside, so that the inner end of the seesaw bar 401 is directed obliquely toward the upper portion of the screw 301. Thus, the tilting rod 401 and the pressing plate 403 can be more favorably prevented from stopping the screw 301, and the screw 301 is prevented from falling back downwards.

The pulling piece 404 can pull the pressing plate 403 away from the screw 301, and at the same time, the inner end of the tilting rod 401 can tilt and be separated from the screw 301 through the pulling force on the outer end of the tilting rod 401, and finally the function of "releasing the stroke obstruction of the pressing plate 403 to the screw 301" is achieved.

In practical use, preparation work (fixing the drainage wire to be subjected to fire on the wiring part of the wire clamp main body 100 in advance) can be performed firstly; then, the hook head 102 of the wire clamp main body 100 is hooked on the main guide wire, so that the integral suspension of the wire clamp is realized; then, pulling the traction piece 404, temporarily removing the stroke limitation of the pressing plate 403 on the screw 301, pushing the sliding assembly 300 upwards, enabling the clamping block 302 to quickly slide upwards to contact the bottom of the main guide line, then loosening the traction piece 404, and recovering the obstruction of the pressing plate 403 on the screw 301, so that the screw 301 cannot automatically slide down; finally, the screw 301 is controlled by an insulating rod to rotate a few circles slightly, so that the screw 301 can be driven to rotate upwards and tighten under the matching of the internal thread 403a of the pressing plate 403, and the clamping and fixing of the main guide wire are realized (the clamp block 302 tightly presses and fastens the main guide wire in the groove of the hook head 102).

In the field operation process, the sliding assembly 300 is pushed upwards only, and the main guide wire can be fixed by slightly screwing the screw 301, so that the process that the screw 301 needs to be screwed for a long time and multiple turns by holding the insulating rod in the prior art is omitted, and a large amount of field operation time is saved. Meanwhile, the wire clamp is very convenient to disassemble, the pressing plate 403 can be separated from the screw 301 only by pulling the traction piece 404 downwards, the screw 301 for removing the limit can automatically fall back downwards due to dead weight, the main guide wire is loosened, and the wire clamp is convenient to disassemble.

Further, the tilting rod 401 comprises an inner rod section 401a, an outer rod section 401b and a hinge point 401c arranged between the inner rod section 401a and the outer rod section 401b, and the three are integrally formed; the side of the transmission box 200 is provided with a window 203 matched with the rotation range of the tilting rod 401, and the outer end of the outer rod section 401b extends out of the transmission box 200 from the window 203 of the transmission box 200.

The hinge point 401c is rotationally fixed in the transmission box 200 through a rotating shaft 401 e; the upper end of the pressure plate 403 is hinged to the inner end of the inner rod section 401 a; the outer rod section 401b is provided with a through-up slit 401b-1, and the outer end of the slit 401b-1 is fixed with a redirection column 401 d. One end of the pulling member 404 is fixed to the bottom of the pressing plate 403, and the other end thereof passes through the inside of the slit 401b-1 and extends downward after passing around the outer periphery of the direction-changing column 401 d.

Further, in order to ensure that the pressing plate 403 can be continuously pressed on the outer side surface of the screw 301 in a normal state, and a locking state is maintained, the invention sets that: the outer side surface of the pressing plate 403 is fixed with a second pressing member 403b, and the second pressing member 403b is positioned between the pressing plate 403 and the tilting rod 401 and presses on the tilting rod 401. The second pressing member 403b is a spring piece integrally formed on the pressing plate 403.

Further, the pulling member 404 includes a pulling rope 404a having one end fixed to the lower end of the pressing plate 403 and a pulling rod 404b fixed to the other end of the pulling rope 404 a. The pulling rope 404a is a flexible and non-retractable rope, and the pulling rod 404b is a linear guide rod structure.

The lower end of the transmission case 200 is provided with a slide 204 fitted with a pull rod 404b, the pull rod 404b passes through the slide 204, and a pull ring 404c is fixed at the lower end thereof. Therefore, the pulling ring 404c of the pulling member 404 is pulled to pull the pulling cable 404a downward, and the pulling cable 404a can directly pull the pressing plate 403 to rotate outward (so that the lower end of the pressing plate 403 is separated from the screw 301), and can also drive the tilting rod 401 to rotate along with the pressure of the direction-changing column 401d, so that the inner end of the tilting rod is tilted and separated from the screw 301; therefore, the cocking rod 401 and the pressing plate 403 can be separated from the screw 301 at the same time only by pulling the pull ring 404c of the invention, and finally, the function of effectively removing the stroke obstruction is achieved, thereby facilitating the detachment of the wire clamp.

When the pull rod 404b is released, the cooperation of the first extrusion 402 and the second extrusion 403b can cause the check assembly 400 to reset.

Further, the sliding assembly 300 further includes a guide housing 303 fitted to the first opening 202 (the outer peripheral contour of the cross section of the guide housing 303 is fitted to the contour of the first opening 202).

The guide shell 303 has a strip-shaped receiving cavity 303a inside, a side of the guide shell 303 corresponding to the tilting rod 401 has a lateral opening 303b, and a second through hole 303c is formed at a lower end of the guide shell 303.

The clamping block 302 is fixed at the top of the guide shell 303 and is positioned at the upper end of the screw 301; the screw 301 is rotatably disposed in the strip-shaped accommodating cavity 303a of the guide shell 303 and passes through the second through hole 303c, and the guide shell 303 and the screw 301 can slide in the first through hole 202. The pressing plate 403 is able to penetrate the lateral opening 303b of the guide housing 303 and is in contact engagement with the screw 301 by its internal thread 403 a.

Thus, the operation of the wire clamp in the fixing process is optimized, so that the sliding assembly 300 can slide up and down in the first penetrating port 202 conveniently. Preferably, the outer contour of the cross section of the guide shell 303 is square, and the first through hole 202 is also a square hole matched with the guide shell, so that the guide shell 303 can only drive the clamping block 302 at the upper end of the guide shell to linearly slide up and down, but cannot circumferentially rotate (and the screw 301 in the sliding assembly 300 can circumferentially rotate inside the guide shell 303).

Further, the sliding assembly 300 further includes a pulling member 304, one end of the pulling member 304 is fixedly connected to the guide housing 303, and the other end of the pulling member 304 is fixedly connected to the lower end of the transmission case 200, and tends to pull the guide housing 303 downward. Therefore, the falling-back reset of the entire slide assembly 300 during the clip removal process can be more facilitated. Preferably, the pulling member 304 is an extension spring coupled between the guide housing 303 and the gear box 200.

Further, in order to ensure that the screw 301 can only rotate in the circumferential direction within the strip-shaped receiving cavity 303a of the guide housing 303, but cannot move up and down relative to the guide housing 303, the sliding assembly 300 of the present invention further includes an adapter ring 305 connected to the upper end of the screw 301 and a longitudinal screw 306.

Specifically, the adapter ring 305 is an annular structure, a ring of annular grooves 305a are formed in the periphery of the adapter ring 305, an axially through channel 305b is formed in the center of the adapter ring 305, and a limiting groove 305c is formed in the outer edge of the lower end of the adapter ring 305. A screw hole 301b opposite to the channel 305b is arranged at the center of the upper end of the screw 301, and a limit bump 301c matched with the limit groove 305c is arranged at the outer edge of the upper end of the screw 301. When the adapter ring 305 is required to be fixed on the top of the screw 301, the limiting projection 301c can be inserted into the limiting groove 305c and can be fixed in the screw hole 301b by passing through the channel 305b and rotating through the longitudinal screw 306. In this way, the adapter ring 305 cannot rotate or displace relative to the screw 301.

The upper end of the guide shell 303 is provided with a rotary accommodating cylinder 303d matched with the outer diameter of the adapter ring 305, the adapter ring 305 is rotatably arranged in the rotary accommodating cylinder 303d, a lateral screw hole 303d-1 corresponding to the position of the annular groove 305a is transversely arranged on the rotary accommodating cylinder 303d, and the axial direction of the lateral screw hole 303d-1 is perpendicular to the axial direction of the screw 301. The clamping block 302 is sleeved on the periphery of the rotary accommodating cylinder 303d, and the clamping block 302 is also provided with a lateral through hole 302a corresponding to the annular groove 305 a. The lateral through hole 302a is opposite to the lateral screw hole 303d-1, and is transversely inserted and bound by the lateral screw 307, and the inner end of the lateral screw 307 extends into the annular groove 305a, so that not only can the circumferential rotation of the adapter ring 305 be guided, but also the position of the adapter ring 305 (and the screw 301) in the guide shell 303 can be limited, and in addition, the clamping block 302 can be detachably fixed on the top of the guide shell 303.

Preferably, the upper end of the clamping block 302 is provided with a concave constraining groove 302b, and the constraining groove 302b is a concave arc-shaped contour for better clamping and limiting the main guide wire. The clamp blocks 302 can be configured with constraint grooves 302b with different specifications, so that the clamp blocks 302 with the proper specification can be selected on site according to the outer diameter of the main guide wire by virtue of the detachable design of the clamp blocks 302, and the clamp blocks are more flexible and can be recycled.

Further, the lower end of the screw 301 passes through the guide case 303, and is provided with a fastening ring 301d at the end thereof, so as to facilitate the pushing or rotating operation of the fastening ring 301d by the insulating rod.
