Abstract
Description
Technical Field
[0001] This utility model relates to the field of line chuck technology, specifically to a construction line chuck. Background Technology
[0002] During construction, it is necessary to pre-embed and lay cables within the building. The cables are wound on a reel, and a chuck is used to facilitate the rapid release of the cables, making it easier for construction workers to pre-embed and lay them.
[0003] The existing patent authorization announcement number CN218950715U discloses a construction line chuck. By designing the connection block and the line spool to be inserted, the line spool can be set inside the housing for use. The connection block and the line spool can be separated by pulling the connecting strip, which facilitates the disassembly of the line spool. The groove, the protrusion and the first spring work together to provide a certain resistance to the rotation of the handle. After the handle is rotated, it can play a certain limiting role.
[0004] In the aforementioned patent, the spool is placed between the square blocks and connecting blocks on the left and right sides. However, the spacing between the square blocks and connecting blocks cannot be flexibly adjusted, making it impossible for the narrower spool to be used between the square blocks and connecting blocks. At the same time, the protrusion in its limiting mechanism is always stuck in the groove and cannot be adjusted. When the operator turns the handle, the protrusion is continuously inserted and ejected in the annular groove, making the operation more difficult. Utility Model Content
[0005] The purpose of this utility model is to address the shortcomings of existing technologies by providing a construction line chuck that allows for flexible adjustment and fixing of the line chuck, as well as flexible adjustment of the handle limit state, thus facilitating operation.
[0006] To achieve the above objectives, this utility model provides the following technical solution: a construction line chuck, comprising a base and a line spool. A lower protective shell is fixedly installed on the top of the base, and an upper protective shell is movably hinged to the top of the lower protective shell. An adjusting clamping assembly is movably installed on the right side of the base, and a hexagonal clamp head is rotatably installed on the left side of the base. A rotating assembly is fixedly connected to the outer side of the hexagonal clamp head. The adjusting clamping assembly includes two guide rods fixedly installed horizontally below the base. A sliding plate located on the right side of the base is movably installed outside the two guide rods. An adjusting screw is rotatably connected to the right side of the sliding plate. The adjusting screw penetrates the right side wall of the base and is threadedly connected to the right side wall of the base. A handwheel is fixedly connected to the right end of the adjusting screw. A limit ring is fixedly installed on the left side of the sliding plate. A bearing sleeve is movably clamped inside the limit ring. A circular clamp head coaxial with the hexagonal clamp head is movably installed inside the bearing sleeve. The line spool is movably clamped between the hexagonal clamp head and the circular clamp head.
[0007] Preferably, the two guide rods are arranged symmetrically in front and behind the base, located inside the base.
[0008] Preferably, the bottom of the sliding plate is attached to the bottom of the base.
[0009] Preferably, the adjusting screw and the circular clamp are arranged on the same axis.
[0010] Preferably, the left side of the base has a limiting hole arranged in a ring around the hexagonal clamp head. The rotating assembly includes a handle fixedly connected to the outside of the hexagonal clamp head and located outside the base. The handle has an installation groove inside that corresponds to the position of the limiting hole. A clamp rod that is locked in the limiting hole is slidably installed inside the installation groove. A limiting piece that is locked in the installation groove is fixedly connected to the outside of the clamp rod. A pull plate is fixedly installed at the end of the clamp rod away from the limiting piece. A spring located between the limiting piece and the pull plate is movably sleeved on the outside of the clamp rod. A stop block that is misaligned with the installation groove is fixedly connected to the left side of the handle.
[0011] Preferably, the width of the abutment corresponds to the depth of the limiting hole.
[0012] Preferably, the left and right sides of the coil are respectively provided with card holes corresponding to the hexagonal card head and the circular card head.
[0013] Compared with the prior art, the beneficial effects of this utility model are:
[0014] 1. By locking the left end of the spool into the hexagonal clamp, rotating the handwheel drives the adjusting screw to rotate, pushing the sliding plate towards the hexagonal clamp. The two guide rods and the adjusting screw work together to guide and limit the sliding plate, allowing the circular clamp to engage with the right side of the spool, thus limiting and fixing the spool. The fixing is adjusted according to the width of the spool, adapting to spools of different widths, thus improving versatility and practicality.
[0015] 2. Pull the pull plate to move the locking rod to the left and release the limit hole. Rotate the pull plate downwards to press against the outer wall of the stop block to prevent the locking rod from springing back into the limit hole. At this time, the handle can rotate freely, releasing the contact between the pull plate and the stop block. The spring applies force to make the locking rod re-lock into the limit hole, forming a stable limit. This method simplifies the operation steps of releasing the limit and can quickly limit the position when the handle needs to be fixed, reducing the amount of force required for the operator to turn the handle, making it convenient and flexible to use.

[0022] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.
[0023] Please see Figure 1 , Figure 2 and Figure 3 This utility model provides a technical solution: a construction line chuck, including a base 1 and a line spool 4. A lower protective shell 2 is fixedly installed on the top of the base 1, and an upper protective shell 3 is movably hinged to the top of the lower protective shell 2. An adjusting clamping assembly 5 is movably installed on the right side inside the base 1, and a hexagonal clamp head 7 is rotatably installed on the left side inside the base 1. A rotating assembly 6 is fixedly connected to the outside of the hexagonal clamp head 7. The adjusting clamping assembly 5 includes two guide rods 51 fixedly installed horizontally below the base 1. A sliding plate 52 located on the right side inside the base 1 is movably installed outside the two guide rods 51. An adjusting screw 53 is rotatably connected to the right side of the sliding plate 52. The adjusting screw 53 penetrates the right side wall of the base 1 and is threadedly connected to the right side wall of the base 1. A handwheel 54 is fixedly connected to the right end of the adjusting screw 53. A limit ring 55 is fixedly installed on the left side of the sliding plate 52. A bearing sleeve 56 is movably clamped inside the limit ring 55. A bearing sleeve 56 is movably installed inside the bearing sleeve 56 and is coaxially aligned with the hexagonal clamp head 7. The circular clamp 8 and the spool 4 are movably engaged between the hexagonal clamp 7 and the circular clamp 8. By clamping the left end of the spool 4 onto the hexagonal clamp 7, rotating the handwheel 54 drives the adjusting screw 53 to rotate, pushing the sliding plate 52 towards the hexagonal clamp 7. The two guide rods 51 work together with the adjusting screw 53 to provide guidance and limit the sliding plate 52, allowing the circular clamp 8 to engage with the right side of the spool 4, thus limiting and fixing the spool 4. The fixing is adjusted according to the width of the spool 4 to accommodate different width specifications of wire. The reel 4 enhances versatility and practicality. During the process, the bearing sleeve 56 can rotate adaptively with the circular clamp 8, avoiding jamming or wear caused by the rigid connection at the fixed end when the reel 4 rotates. When the reel 4 needs to be disassembled, the handwheel 54 is rotated in the opposite direction, and the adjusting screw 53 drives the sliding plate 52 to move to the right, separating the circular clamp 8 from the reel 4. The reel 4 can then be directly removed from the hexagonal clamp 7. The operation is convenient and efficient. The rotation of the hexagonal clamp 7 drives the reel 4 to rotate stably for winding and unwinding operations.
[0024] Two guide rods 51 are symmetrically arranged at the bottom of the base 1, with their ends fixedly connected to the inner wall of the base 1. They can maintain stable guiding performance during long-term use, effectively preventing the sliding plate 52 from shifting or shaking when moving. This ensures the accuracy and reliability of the circular clamp 8 in fixing the coil 4. Together with the adjusting screw 53, they form a stable transmission and guiding system, providing stable support for the quick replacement and stable operation of the coil 4.
[0025] The bottom of the sliding plate 52 is attached to the bottom of the base 1. The sliding plate 52 has a certain thickness and is attached to the bottom of the base 1, which provides a certain support for the sliding plate 52, enhances its structural stability when moving in the horizontal direction, and avoids tilting due to uneven force.
[0026] The adjusting screw 53 and the circular clamp 8 are set on the same axis, which ensures that the direction of force transmission of the adjusting screw 53 is always consistent with the central axis of the circular clamp 8 during the movement of the circular clamp 8. This avoids the phenomenon of skew or jamming when the circular clamp 8 contacts the wire reel 4 due to eccentric force, and realizes precise control of the position of the circular clamp 8. This allows the circular clamp 8 to apply clamping force to the wire reel 4 smoothly and evenly, improves the concentricity of the wire reel 4 after installation, reduces the radial runout of the wire reel 4 during rotation, and thus ensures the stability and accuracy of wire winding and unwinding operations.
[0027] The left and right sides of the coil 4 are respectively provided with locking holes corresponding to the hexagonal locking head 7 and the circular locking head 8. The shape and size of the locking holes are adapted to the hexagonal locking head 7 and the circular locking head 8 respectively. When the coil 4 is installed, the hexagonal locking head 7 can be inserted into the locking hole on the left side of the coil 4, and the circular locking head 8 can be inserted into the locking hole on the right side of the coil 4. This can effectively restrict the rotation of the coil 4 in the circumferential direction, ensure the stable rotation of the coil 4, and avoid relative slippage.
[0028] Please see Figure 3 , Figure 4 and Figure 5 The base 1 has a limiting hole 11 arranged in a ring around the hexagonal collet 7 on its left side. The rotating assembly 6 includes a handle 61 fixedly connected to the outside of the hexagonal collet 7 and located outside the base 1. The handle 61 has a mounting groove 62 corresponding to the position of the limiting hole 11 inside. A locking rod 63 is slidably installed inside the mounting groove 62 and locked in the limiting hole 11. A limiting piece 64 is fixedly connected to the outside of the locking rod 63 and locked in the mounting groove 62. A pull plate 66 is fixedly installed at the end of the locking rod 63 away from the limiting piece 64. A spring 65 is movably sleeved on the outside of the locking rod 63 between the limiting piece 64 and the pull plate 66. The left side of the handle 61 is fixedly connected to... The abutment 67, which is offset from the mounting slot 62, can be pulled by the pull plate 66 to move the locking rod 63 and the limiting piece 64 to the left, compressing the spring 65. At this time, the locking rod 63 disengages from the limiting hole 11 and is released from the limit. Rotating the pull plate 66 downwards so that it abuts against the outer wall of the abutment 67 prevents the locking rod 63 from springing back into the limiting hole 11, allowing the handle 61 to rotate freely. Rotating the pull plate 66 to disengage it from the abutment state with the abutment 67, the spring 65 applies force to lock the locking rod 63 into the limiting hole 11, forming a stable limit and preventing the handle 61 from rotating on its own. This simplifies the operation steps when releasing the limit and allows for quick and easy limit setting when the position of the handle 61 needs to be fixed, making it convenient and flexible to use.
[0029] The width of the abutment 67 corresponds to the depth of the limiting hole 11. When the pull plate 66 abuts against the outer wall of the abutment 67, the abutment 67 can provide stable support for the pull plate 66, ensuring that the lever 63 always remains detached from the limiting hole 11, and preventing the pull plate 66 from accidentally shifting due to the elastic potential energy of the spring 65. At the same time, the misalignment of the abutment 67 and the mounting groove 62 ensures that the abutment 67 will not interfere with the internal structure of the mounting groove 62 during the rotation of the handle 61. This simplifies the operation steps when releasing the limit and allows for quick setting of the limit when the handle 61 needs to be fixed, effectively balancing the relationship between operational flexibility and structural stability.
[0030] Working principle: By opening the lower protective shell 2 and locking one end of the coil 4 inside the base 1 with the hexagonal clamp 7 on the left side, the handwheel 54 on the right side of the base 1 is rotated. The rotation of the handwheel 54 drives the adjusting screw 53 to rotate, which pushes the sliding plate 52 towards the hexagonal clamp 7. The two guide rods 51, together with the adjusting screw 53, can provide guidance and limit for the sliding plate 52, so that the circular clamp 8 installed on the side of the sliding plate 52 near the hexagonal clamp 7 can be inserted into the clamp hole on the side of the coil 4 from the right side of the coil 4 to limit and fix the coil 4. The adjustment and fixation are made according to the width of the coil 4.
[0031] Pulling the pull plate 66 outward with your finger causes the lever 63 and the limiting piece 64 to slide towards the abutment block 67 in the mounting groove 62, compressing the spring 65 and causing the lever 63 to disengage from the limiting hole 11. Then, by rotating the pull plate 66 downward, the pull plate 66 is pressed against the abutment block 67 to prevent the lever 63 from springing back into the limiting hole 11. The handle 61 can rotate freely. Rotating the handle 61 causes the hexagonal chuck 7 to rotate, which in turn causes the spool 4 to rotate for wire feeding.
[0032] After the wire is retracted, the pull plate 66 is rotated to drive the locking rod 63 to rotate within the mounting groove 62, causing the pull plate 66 to disengage from the outer abutment state of the stop block 67. This allows the spring 65 to push the limiting plate 64 and the locking rod 63 to slide towards the limiting hole 11, so that the end of the locking rod 63 is engaged in the limiting hole 11 to restrict the throttle 61 and prevent the throttle 61 from rotating on its own. The above is the working process of the entire device. All contents not described in detail in this specification are existing technologies known to those skilled in the art.
[0033] Although embodiments of the present invention have been shown and described, it will be understood by those skilled in the art that various changes, modifications, substitutions and alterations can be made to these embodiments without departing from the principles and spirit of the present invention, the scope of which is defined by the appended claims and their equivalents.
