Description

Technical Field

[0001] This utility model belongs to the technical field of auxiliary tools for wire installation, and specifically relates to a wire terminal take-up clamp. Background Technology

[0002] During the finishing work of cables, workers typically use cable clamps to bind the cable end to the cable body to secure it and ensure the safety of the cable installation. Specifically, the cable end must be pre-tied to the cable body before the clamp can be installed.

[0003] The current method for pre-tying the cable tail to the cable body uses iron wire. The specific procedure is as follows: the worker first bends the cable tail and cable body together to tighten them, then uses iron wire to wrap around the cable tail and cable body to secure them, thus completing the pre-tying. After pre-tying, the cable tail will not separate from the cable body, making it very convenient to install the cable clamp. However, this method of pre-tying with iron wire is cumbersome, time-consuming, labor-intensive, and inefficient. Utility Model Content

[0004] To address the shortcomings of the existing technology, the purpose of this utility model is to provide a cable end take-up clamp that enables rapid pre-tightening of the cable end and the cable body.

[0005] To achieve the above objectives, the technical solution adopted by this utility model is as follows: a wire terminal take-up clamp, including a clamp frame with an opening, a closed structure for opening and closing the clamp frame opening, a clamp block slidably disposed on the clamp frame, and a pushing mechanism that can push the clamp block to slide and move closer to and away from the closed structure.

[0006] In the above scheme, during use, first operate the pushing mechanism to slide the clamp block backward away from the closed structure, and then operate the closed structure to open the clamp frame opening. Next, insert the cable body into the clamp frame opening and bend the cable tail into the clamp frame. Then, operate the closed structure to close the clamp frame opening. At this point, both the cable body and the cable tail are positioned within the clamp frame between the corresponding closed structure and the clamp block. Finally, operate the pushing mechanism to slide the clamp block forward, bringing it closer to the closed structure, so that the clamp block and the closed structure clamp the cable body and cable tail together, completing the pre-binding operation of the cable tail and cable body. This is convenient to operate. Under the mutual clamping action of the clamp block and the closed structure, the cable tail cannot be separated from the cable body, thus facilitating the installation of the clamp. After the clamp is installed, operate the closed structure to open the clamp frame opening to disassemble and separate the cable retractor from the cable tail and cable body. The disassembly and assembly operations are convenient and quick.

[0007] Furthermore, the aforementioned pushing mechanism includes a lead screw threadedly connected to the clamp frame. Rotating the lead screw causes it to move back and forth along the clamp frame. The front end of the lead screw is rotatably connected to the clamp block, and the rear end of the lead screw extends out of the clamp frame to facilitate tightening the lead screw. This design, by rotatably connecting the front end of the lead screw to the clamp block, ensures that the clamp block does not obstruct the rotation of the lead screw. When the lead screw moves back and forth along the clamp frame, it simultaneously drives the clamp block to slide, thereby achieving the structural function of the aforementioned pushing mechanism in pushing the clamp block to slide and move closer to or away from the closed structure.

[0008] Furthermore, the aforementioned clamp includes two opposing vertical rods and an end plate located at the rear end of the two vertical rods. A lead screw is located between the two vertical rods and is threadedly connected to the end plate. The two vertical rods and the lead screw are parallel to each other, and an opening in the clamp is formed at the front end between the two vertical rods. The distance between the two vertical rods is greater than the diameter of the cable to ensure that the cable can be inserted between the two vertical rods through the opening in the clamp. The aforementioned clamping block is fitted onto the outside of the two vertical rods through two sliding holes, allowing the clamping block to slide back and forth along the two vertical rods through the sliding holes, resulting in more stable sliding.

[0009] Furthermore, the aforementioned clamping block has a mounting hole on one side opposite to the end plate, a rotating hole is provided on the side wall of the mounting hole, and a convex ring is provided at the front end of the lead screw. The convex ring is placed in the rotating hole, and the diameter of the convex ring is larger than the diameter of the lead screw and the mounting hole, thereby realizing the structural function of rotating connection between the front end of the lead screw and the clamping block. Moreover, the diameter of the convex ring is larger than the diameter of the lead screw and the mounting hole, so that the convex ring cannot come out of the mounting hole, ensuring the connection stability between the lead screw and the clamping block.

[0010] Furthermore, the rear ends of the two vertical rods are threaded to the end plate, ensuring both the stability of the connection between the two vertical rods and the end plate and facilitating their assembly and disassembly. The lead screw has a cap at its rear end, located outside the clamp. During use, the operator can use a drill or other tools in conjunction with the cap to rotate the lead screw, making operation more convenient. Preferably, the cross-section of the cap is hexagonal, allowing for better engagement with the drill's nozzle, enabling the drill to more stably drive the lead screw.

[0011] Furthermore, the aforementioned closed structure includes a locking rod and a limiting block located at the end of the locking rod. The front ends of the two vertical rods are respectively provided with insertion holes facing each other. The diameter of the limiting block is larger than the diameter of the insertion hole to ensure that the limiting block cannot pass through the insertion hole. The locking rod is inserted into the two insertion holes, and the clamping block is located between the locking rod and the end plate. In use, inserting the locking rod into the two insertion holes closes the opening of the clamp holder; disengaging the locking rod from the two insertion holes opens the opening of the clamp holder.

[0012] Furthermore, the aforementioned closed structure also includes a pin, and a locking hole is provided on the side wall of the locking rod. The pin is inserted into the locking hole. When the locking rod is inserted into the two holes, the two vertical rods are positioned between the pin and the limiting block. At this time, the locking rod cannot be dislodged from the two holes due to the restriction of the pin and the limiting block, thus ensuring the stability of the connection between the locking rod and the holes. When it is necessary to open the opening of the clamp, the pin can be pulled out of the locking hole, allowing the locking rod to be pulled out of the two holes and the clamp opening to be opened.

[0013] Furthermore, the locking rod has an external thread on its outer side, and one of the insertion holes has an internal thread that matches the external thread on its inner side. This design, through the threaded connection between the locking rod and the insertion hole, makes the connection between the locking rod and the insertion hole more secure, allowing the locking rod and the clamping block to more firmly clamp the cable tail and the cable body.

[0014] Furthermore, the aforementioned locking rod has a protrusion on its side wall, and both insertion holes have clearance grooves on their inner side walls. The two clearance grooves are aligned. In use, when the locking rod is aligned with the insertion hole and the protrusion is aligned with the clearance groove, the locking rod can pass through the insertion hole, thus inserting the locking rod into the two insertion holes. This positions the two vertical rods between the protrusion and the limiting block. Then, by rotating the locking rod to displace the protrusion and the clearance groove, the opening of the clamp frame can be closed. At this point, the protrusion cannot pass through the insertion hole, preventing the locking rod from dislodging from the insertion hole due to the obstruction of the protrusion and the limiting block, thereby stably closing the opening of the clamp frame. When the protrusion is rotated to align with the clearance groove, the locking rod can be pulled out of the insertion hole to open the opening of the clamp frame.

[0015] Furthermore, the side of the clamping block opposite to the locking rod is provided with an arc-shaped groove between the two vertical rods. Since the cable is a cylindrical structure, the arc-shaped groove cooperates with the outside of the cable, which can further improve the clamping stability of the clamping block on the cable.

[0016] This utility model of a cable retractor allows for quick pre-binding of cable ends, facilitating clamp installation. During operation, simply remove the locking lever to open the clamp holder opening, place the cable body and cable end between the two vertical bars in front of the corresponding clamp block, then insert the locking lever to close the clamp holder opening. Use an electric drill to rotate the screw, pushing the clamp block towards the locking lever, thus clamping the cable end and cable body tightly together. This completes the pre-binding of the cable end and cable body, a convenient and quick operation that saves clamp installation time and improves the efficiency of power transmission line work. After the clamp is installed, the locking lever can be removed again to open the clamp holder opening, allowing for easy and quick disassembly and separation of the retractor from the cable end and cable body.

[0029] The technical solution of this utility model will be further described in detail below through specific embodiments and with reference to the accompanying drawings:

[0030] Example 1

[0031] like Figure 1 , 2 As shown, this embodiment provides a wire terminal take-up clamp, including a clamp frame 1 with an opening, a closed structure for opening and closing the opening of the clamp frame 1, a clamp block 3 slidably disposed on the clamp frame 1, and a pushing mechanism that can push the clamp block 3 to slide closer to and further away from the closed structure.

[0032] Specifically, the aforementioned pushing mechanism includes a lead screw 4 threadedly connected to the clamp 1. Rotating the lead screw 4 causes it to move back and forth along the clamp 1. The front end of the lead screw 4 is rotatably connected to the clamp block 3, and the rear end of the lead screw 4 extends out of the clamp 1 to facilitate tightening. This design, by rotatably connecting the front end of the lead screw 4 to the clamp block 3, ensures that the clamp block 3 does not obstruct the rotation of the lead screw 4. When the lead screw 4 moves back and forth along the clamp 1, it simultaneously drives the clamp block 3 to slide, thereby achieving the structural function of the aforementioned pushing mechanism, which can push the clamp block 3 to slide and move closer to or away from the closed structure.

[0033] like Figure 3 As shown, the clamp 1 includes two opposing vertical rods 11 and an end plate 12 located at the rear end of the two vertical rods 11. A lead screw 4 is located between the two vertical rods 11 and is threadedly connected to the end plate 12. Rotating the lead screw 4 causes it to move back and forth along the end plate 12. The two vertical rods 11 and the lead screw 4 are parallel to each other. An opening of the clamp 1 is formed at the front end between the two vertical rods 11, and the distance between the two vertical rods 11 is greater than the diameter of the cable to ensure that the cable can be inserted between the two vertical rods 11 through the opening of the clamp 1. The clamping block 3 is fitted onto the outside of the two vertical rods 11 through two sliding holes 31, so that the clamping block 3 can slide back and forth along the two vertical rods 11 through the sliding holes 31, making the sliding of the clamping block 3 more stable.

[0034] The aforementioned closed structure includes a locking rod 2 and a limiting block 22 located at the left end of the locking rod 2. The front ends of the two vertical rods 11 are respectively provided with insertion holes 110. The diameter of the limiting block 22 is larger than the diameter of the insertion hole 110 to ensure that the limiting block 22 cannot pass through the insertion hole 110. In use, the locking rod 2 is inserted horizontally into the two insertion holes 110 to close the opening of the clamp frame 1. At this time, the clamping block 3 is located between the locking rod 2 and the end plate 12, and the locking rod 2, clamping block 3 and end plate 12 are parallel to each other. Pulling the locking rod 2 out of the two insertion holes 110 will open the opening of the clamp frame 1.

[0035] When using the wire take-up pliers of this embodiment, as follows: Figure 1 As shown, first pull the locking lever 2 to disengage from the two insertion holes 110 to open the clamp holder 1, and rotate the screw 4 to drive the clamp block 3 to slide backward and away from the opening of the clamp holder 1. Then, insert the cable body between the two vertical rods 11 at the opening of the clamp holder 1, and bend the cable end to insert it between the two vertical rods 11. Figure 2 As shown, insert the locking rod 2 into the two insertion holes 110 to close the opening of the clamp 1. At this time, the cable body and cable tail are located between the locking rod 2 and the clamping block 3. Finally, rotate the screw 4 to drive the clamping block 3 to slide forward and approach the locking rod 2, so that the clamping block 3 and the locking rod 2 clamp each other tightly, and the cable body and cable tail are pressed together. This completes the pre-binding operation of the cable tail and the cable body, which is convenient. At this time, under the clamping action of the clamping block and the locking rod, the cable tail cannot be separated from the cable body, which facilitates the installation of the clamp.

[0036] After the wire clamp is installed, pull the locking lever 2 to disengage it from the two sockets 110 and open the opening of the clamp frame 1. This allows the wire retractor to be disassembled and separated from the cable tail and the cable body. The disassembly and assembly operation is convenient and quick.

[0037] The wire take-up pliers of this embodiment can perform pre-tightening of the cable end to facilitate the installation of the wire clamp. Compared with the existing method of pre-tightening with iron wire, the pre-tightening operation using the take-up pliers of this embodiment is more convenient, simpler, and more efficient.

[0038] As an improvement to this embodiment, an arc-shaped groove 33 is provided on the side of the clamping block 2 opposite to the locking rod 3, corresponding to the position between the two vertical rods 11. Since the cable is a cylindrical structure, the clamping stability of the clamping block 3 on the cable can be further improved by cooperating with the outside of the cable through the arc-shaped groove 33.

[0039] Furthermore, the aforementioned lead screw 4 has a screw cap 41 at its rear end, located outside the clamp holder 1. During use, the operator can use tools such as an electric drill in conjunction with the screw cap 41 to rotate the lead screw 4, making operation more convenient. Preferably, the cross-section of the screw cap 41 is hexagonal. The hexagonal shape of the screw cap 41 allows for better engagement with the drill's nozzle, enabling the drill to more stably drive the lead screw 4 to rotate.

[0040] Example 2

[0041] This embodiment is a further improvement on the wire terminal take-up clamp structure of Embodiment 1. The improvement lies in that, as... Figure 1 As shown, the aforementioned closed structure also includes a pin 21, and the side wall of the locking rod 2 has a locking hole 23, into which the pin 21 is inserted. Figure 2 As shown, when the locking rod 2 is inserted into the two sockets 110, the two vertical rods 11 are located between the pin 21 and the limiting block 22. At this time, the locking rod 2 cannot come out of the two sockets 110 under the restriction of the pin 21 and the limiting block 22, thus ensuring the connection stability between the locking rod 2 and the sockets 110, which can firmly close the opening of the clamp frame 1, and make the locking rod 2 and the clamping block 3 clamp the cable body and the cable tail more firmly.

[0042] When it is necessary to open the opening of the clamp 1, the pin 21 must first be pulled to disengage from the locking hole 23, and then the limit block 22 must be pulled to move the locking rod 2 to the left to disengage from the two insertion holes 110 before the opening of the clamp 1 can be opened.

[0043] As an improvement to this embodiment, in such Figure 3 As shown, the rear ends of the two vertical rods 11 are threaded to the end plate 12, which ensures the stability of the connection between the two vertical rods 11 and the end plate 12, and facilitates the assembly and disassembly of the two vertical rods 11 and the end plate 12.

[0044] In addition, such as Figure 3 , 4 As shown in Figure 5, the clamping block 3 has a mounting hole 32 on one side opposite to the end plate 12. The side wall of the mounting hole 32 has a rotating hole 321. The front end of the lead screw 4 has a protruding ring 42, which is placed in the rotating hole 321. The diameter of the protruding ring 42 is larger than the diameter of the lead screw 4 and the mounting hole 32. The lead screw 4 can rotate along the mounting hole 32, and the protruding ring 42 can rotate along the rotating hole 32. This realizes the structural function of rotating connection between the front end of the lead screw 4 and the clamping block 3. The diameter of the protruding ring 42 is larger than the diameter of the lead screw 4 and the mounting hole 32, so that the protruding ring 42 cannot come out of the mounting hole, ensuring the connection stability between the lead screw 4 and the clamping block 3.

[0045] Example 3

[0046] This embodiment is a further improvement on the wire terminal take-up clamp structure of Embodiment 1. The improvement lies in that, as... Figure 6 As shown, the outer side of the right end of the aforementioned locking rod 2 is provided with an external thread 24, and the inner side of the insertion hole 110 located on the right side is provided with an internal thread that matches the external thread 24.

[0047] When using the wire retractor in this embodiment, to close the opening of the clamp 1, the locking lever 2 can be passed through the insertion hole 110 on the left side, and the right end of the locking lever 2 can be aligned with the opening of the insertion hole 110 on the right side. Simultaneously, the locking lever 2 is rotated clockwise so that the external thread 24 of the locking lever 2 connects with the internal thread of the insertion hole 110 on the right side, thus completing the closing operation of the clamp 1 opening. To open the clamp 1 opening, the locking lever 2 can be rotated counterclockwise so that the external thread 24 of the locking lever 2 disengages from the internal thread of the insertion hole 110 on the right side. Then, the limiting block 22 is pulled to disengage the locking lever 2 from the insertion hole 110 on the right side, thus completing the opening operation of the clamp 1.

[0048] The cable retractor in this embodiment connects the locking bar 2 to the socket 110 on the right side by threading it. This prevents the locking bar 2 from wobbling relative to the socket 110, making the connection between the locking bar 2 and the socket 110 more stable. Consequently, the locking bar 2 and the clamping block 3 can more securely clamp the cable tail and the cable body.

[0049] Example 4

[0050] This embodiment is a further improvement on the wire terminal take-up clamp structure of Embodiment 1. The improvement lies in that, as... Figure 7 , 8 As shown, the locking rod 2 has a protrusion 25 on its side wall and a relief groove 1101 on the inner side wall of both insertion holes 110. The two relief grooves 1101 are aligned. When the locking rod 2 is aligned with the insertion hole 110 and the protrusion 25 is aligned with the relief groove 1101, the locking rod 2 can pass through the insertion hole 110. When the locking rod 2 is inserted into the two insertion holes 110, the two vertical rods 11 are located between the protrusion 25 and the limiting block 22.

[0051] When using the wire retractor in this embodiment, when it is necessary to close the opening of the clamp frame 1, the right end of the locking rod 2 can be aligned with the position of the socket 110 opening, and the protrusion 25 can be aligned with the clearance groove 1101. Then, the locking rod 2 is passed through the two sockets 110 until the two vertical rods 11 are located between the protrusion 25 and the limiting block 22. Then, the locking rod 2 is rotated so that the position of the protrusion 25 and the clearance groove 1101 is offset, and the opening of the clamp frame 1 can be closed. At this time, the position of the protrusion 25 and the clearance groove 1101 is offset, so it cannot pass through the socket 110. Thus, the locking rod 2 cannot come out of the socket 110 under the obstruction of the protrusion 25 and the limiting block 22, so that the opening of the clamp frame can be closed stably.

[0052] When it is necessary to open the opening of the clamp holder 1, the protrusion 25 can be rotated to align with the position of the relief groove 1101, and the locking rod 2 can be pulled out to disengage from the two insertion holes 110, thereby opening the opening of the clamp holder 1, making the operation more convenient.

Those skilled in the art can make other variations or modifications based on the above description. It is neither necessary nor possible to exhaustively describe all embodiments here.
