Description

Technical Field

[0001] This utility model relates to the field of power line conduit cutting technology, and more specifically, to a conduit cutting device. Background Technology

[0002] Power line conduits are specialized pipes used to protect and lay power cables and wires, and are widely used in power engineering, construction engineering, and various industrial and civil facilities. They provide mechanical protection, safety isolation, and path guidance for power lines, ensuring the reliability and safety of power transmission. Power line conduits are important components in power engineering for protecting cables and wires, and are typically made of materials such as PE and PVC.

[0003] In power construction, conduits, as crucial components for protecting cables and wires, need to be cut to different lengths according to actual requirements. Currently, small-diameter conduits are typically cut using a hacksaw or shears. However, manual cutting with a hacksaw is inefficient, labor-intensive, and prone to producing non-perpendicular or burr-like cuts, requiring subsequent trimming and impacting construction efficiency and quality. Using shears, on the other hand, can cause the cut to deform under pressure during the cutting process, resulting in poor cut quality and requiring further adjustments, also affecting construction efficiency.

[0004] In view of this, the present invention proposes a conduit cutting device to solve the above problems. Utility Model Content

[0005] To address the shortcomings of existing technologies, this utility model provides a conduit cutting device to solve the problems of low cutting accuracy, poor cut quality, and low operating efficiency in the prior art. This device can clamp and cut the conduit, is easy and quick to operate, ensures a flat and vertical cut, requires no subsequent trimming, and improves cutting efficiency.

[0006] To achieve the above objectives, the technical solution adopted by this utility model is as follows:

[0007] A conduit cutting device includes a movable clamp head, a fixed clamp head, and a support. The movable clamp head and the fixed clamp head are of the same specifications. The movable clamp head is movably disposed on the left side of the fixed clamp head. Positioning grooves for fitting the conduit are formed on the inner surfaces of both the movable and fixed clamp heads. A support is fixedly mounted on the upper side of the right end face of the fixed clamp head. A connecting arm is fixedly mounted on the upper side of the right end face of the movable clamp head. A toothed plate is fixedly mounted on the upper side of the connecting arm. The support and the upper surface of the fixed clamp head have U-shaped sliding grooves adapted to the connecting arm and the toothed plate. The support arm is inserted into the slide groove and slidably connected thereto. An adjusting worm gear for driving the toothed plate to move is installed on the upper end of the support. The adjusting worm gear is connected to the toothed plate. A knife box is fixed on the right side of the fixed clamp head. A cutting blade is provided inside the knife box. Its left end is the cutting tip. An adjusting screw is rotatably connected to the right end of the cutting blade through a connector. The right end of the adjusting screw passes through the knife box and is connected to it through a threaded adjustment. An adjusting knob is provided on the right end of the adjusting screw. A knife groove adapted to the cutting blade is opened through the inside of the fixed clamp head. The left tip of the cutting blade extends into the knife groove.

[0008] Furthermore, the positioning groove has an arc-shaped structure.

[0009] Furthermore, a plastic pad is attached to the positioning groove on the movable pliers head, and its longitudinal width is greater than the longitudinal width of the movable pliers head.

[0010] Furthermore, a groove is vertically formed at the center of the pad, and a spring strip adapted to it is provided inside the groove. The thickness of the spring strip is less than the depth of the groove. The bottom of the spring strip is fixed to the bottom of the groove, while its upper end is not fixed.

[0011] Furthermore, a handle is fixedly provided at the right end of the support, and a rubber grip is fitted on the outside of the handle, with anti-slip textures engraved on the surface of the grip.

[0012] Furthermore, a limiting baffle is fixed at the right end of the toothed plate, and the height of the limiting baffle is greater than the height of the axis of the adjusting worm gear.

[0013] Compared with the prior art, the present invention has the following beneficial effects:

[0014] 1. This utility model achieves clamping and cutting of conduit through a mechanical structure, which is simple and quick to operate, greatly improving cutting efficiency. It avoids the problems of non-perpendicular or burr cuts that are easy to occur when cutting with a hacksaw, as well as the problem of deformation of the cut due to pressure caused by cutting with a shear. It can ensure that the cut is flat and perpendicular, without the need for subsequent trimming, thus improving construction efficiency and quality.

[0015] 2. The movable pliers head of this utility model is movably located on the left side of the fixed pliers head. This layout facilitates the clamping operation of the conduit by moving the movable pliers head. Both the movable and fixed pliers heads have positioning grooves on their inner surfaces for fitting the conduit. These grooves provide a stable placement for the conduit, ensuring its stability during cutting. An adjusting worm gear is installed at the upper end of the support to drive the movement of the toothed plate. The adjusting worm gear is connected to the toothed plate; rotating the adjusting worm gear drives the toothed plate to move, which in turn moves the movable pliers head, thus achieving the clamping or releasing operation of the conduit.

[0016] 3. The knife box of this utility model is equipped with a cutting blade, the left end of which is a cutting tip. The tip of the cutting blade can penetrate into the tube, and the tube can be cut by the subsequent rotation of the cutting blade. The right end of the cutting blade is rotatably connected to an adjusting screw through a connector. The right end of the adjusting screw is equipped with an adjusting knob. By rotating the adjusting knob, the adjusting screw can be rotated, thereby adjusting the position of the cutting blade and controlling the depth of the cutting blade into the tube.

[0017] 4. In this utility model, a plastic pad is adhered to the positioning groove on the movable pliers head, and its longitudinal width is greater than that of the movable pliers head. The plastic pad acts as an isolation and buffer, preventing direct contact between the surface of the conduit and the surface of the movable pliers head, reducing damage to the conduit surface, protecting the integrity of the conduit, and at the same time, the wider design can better wrap around the conduit, increasing the contact area and friction with the conduit, thereby clamping the conduit more stably, effectively limiting the radial sway of the conduit, and ensuring the accuracy of the conduit position during the cutting process.

[0018] 5. In this utility model, a groove is vertically formed at the center of the pad, and a spring strip adapted to fit the groove is provided inside the groove. The thickness of the spring strip is less than the depth of the groove. The bottom of the spring strip is fixed to the bottom of the groove, while its upper end is not fixed. The spring strip is used to aim at the position to be cut on the marked tube, providing the operator with a visual reference and improving cutting accuracy. At the same time, during the cutting process, the spring strip is pressed into the groove by the tube, without interfering with the cutting of the tube. Attached Figure Description

Detailed Implementation

[0026] The technical solutions of this utility model will be clearly and completely described below with reference to the embodiments of this utility model. Obviously, the described embodiments are only some embodiments of this utility model, and not all embodiments. Based on the embodiments of this utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of this utility model.

[0027] Example:

[0028] like Figures 1 to 6As shown, a conduit cutting device includes a movable clamping head 1, a fixed clamping head 2, and a support 3. The movable clamping head 1 and the fixed clamping head 2 are of the same specifications. The movable clamping head 1 is movably disposed on the left side of the fixed clamping head 2. This arrangement facilitates the clamping operation of the conduit by moving the movable clamping head 1. Positioning grooves 9 for fitting the conduit are provided on the inner surfaces of both the movable clamping head 1 and the fixed clamping head 2. The positioning grooves 9 provide a stable placement position for the conduit, ensuring its stability during the cutting process. A support 3 is fixedly mounted on the upper side of the right end face of the fixed clamp head 2, and a connecting arm 12 is fixedly mounted on the upper side of the right end face of the movable clamp head 1. A toothed plate 13 is fixedly mounted on the upper side of the connecting arm 12. The support 3 and the upper end face of the fixed clamp head 2 are provided with a sliding groove 15 of an L-shape structure that is adapted to the connecting arm 12 and the toothed plate 13. The connecting arm 12 is inserted into the sliding groove 15 and slidably connected to it. The movable clamp head 1 and the fixed clamp head 2 are movably connected through the support 3, the connecting arm 12 and the sliding groove 15, ensuring that the movable clamp head 1 can move smoothly. An adjusting worm gear 14 for driving the toothed plate 13 to move is installed on the upper end of the support 3. The adjusting worm gear 14 is connected to the toothed plate 13. By rotating the adjusting worm gear 14, the toothed plate 13 can be driven to move, thereby driving the movable clamp head 1 to move, realizing the clamping or loosening operation of the conduit. A blade box 10 is fixedly mounted on the right side of the fixed pliers head 2. Inside the blade box 10 is a cutting blade 16, the left end of which is a cutting tip. The tip of the cutting blade 16 can penetrate into the conduit, and subsequent rotation of the cutting blade 16 cuts the conduit. An adjusting screw 17 is rotatably connected to the right end of the cutting blade 16 via a connector. The right end of the adjusting screw 17 passes through the blade box 10 and is threadedly connected to it. An adjusting knob 11 is located on the right end of the adjusting screw 17. Rotating the adjusting knob 11 rotates the adjusting screw 17, thereby adjusting the position of the cutting blade 16 and controlling the depth to which the cutting blade 16 cuts into the conduit. A blade groove 18, adapted to the cutting blade 16, is formed inside the fixed pliers head 2. The left tip of the cutting blade 16 extends into the blade groove 18, ensuring that the cutting blade 16 accurately cuts into the conduit during the cutting process. Simultaneously, the blade groove 18 guides the cutting blade 16, ensuring the accuracy of the cutting direction. This design solves the problems of low efficiency, high labor intensity, and non-perpendicular or burr-prone cuts caused by manual cutting with hacksaws in existing technologies, which require subsequent trimming and affect construction efficiency and quality; and the problems of cutting with shears causing the cut to deform under pressure during the cutting process, resulting in poor cut quality and requiring subsequent adjustments, which also affect construction efficiency.

[0029] In this embodiment, the positioning groove 9 is an arc-shaped structure. The arc-shaped positioning groove 9 is used to fit the conduit, which can stably fit the circular surface of the conduit, provide a stable placement position for the conduit, and ensure the stability of the conduit during the cutting process.

[0030] In this embodiment, a plastic pad 6 is adhered to the positioning groove 9 on the movable clamp head 1, and its longitudinal width is greater than the longitudinal width of the movable clamp head 1. The plastic pad 6 can act as an isolation and buffer, avoiding direct contact between the surface of the conduit and the surface of the movable clamp head 1, reducing damage to the surface of the conduit, protecting the integrity of the conduit, and at the same time, the wider design can better wrap the conduit, increase the contact area and friction with the conduit, thereby clamping the conduit more stably, effectively limiting the radial sway of the conduit, and ensuring the accuracy of the conduit position during the cutting process.

[0031] In this embodiment, a vertical groove 7 is formed at the center of the pad 6. A spring strip 8, adapted to the groove 7, is provided inside the groove 7. The thickness of the spring strip 8 is less than the depth of the groove 7. The bottom of the spring strip 8 is fixed to the bottom of the groove 7, while its upper end is not fixed. The spring strip 8 is used to aim at the position to be cut on the marked tube, providing the operator with a visual reference and improving cutting accuracy. Simultaneously, during the cutting process, the spring strip 8 is pressed into the groove 7 by the pressure of the tube, preventing interference with the cutting of the tube.

[0032] In this embodiment, a handle 4 is fixedly mounted on the right end of the support 3, and a rubber grip sleeve 5 is fitted over the outside of the handle 4. The surface of the grip sleeve 5 is engraved with anti-slip textures. The rubber material is soft and has a certain degree of plasticity, which can better conform to the curve of the operator's hand and provide a more comfortable grip. Compared with metal or hard plastic handles 4, the rubber grip sleeve 5 reduces the hard contact between the hand and the handle 4 and increases the comfort of gripping. In addition, the anti-slip textures on the surface of the grip sleeve 5 increase the friction between the hand and the handle 4, preventing the hand from slipping and ensuring that the operator can stably and accurately control the support 3 and the cutting blade 16, thus ensuring operational safety.

[0033] In this embodiment, a limiting baffle 121 is fixedly provided at the right end of the toothed plate 13. The height of the limiting baffle 121 is greater than the axial height of the adjusting worm gear 14. The limiting baffle 121 plays a limiting role in the movement of the toothed plate 13 and the connecting support arm 12, which can accurately limit the movement range of the toothed plate 13 and prevent it from disengaging from the effective meshing area with the adjusting worm gear 14 due to excessive movement, thereby causing the connecting support arm 12 to disengage from the slide groove 15 and affecting the use effect.

[0034] The working principle of this conduit cutting device is as follows:

[0035] In practical use, first, rotate the adjusting worm gear 14. This drives the toothed plate 13 to move, which in turn moves the movable jaw 1, increasing the opening between the movable jaw 1 and the fixed jaw 2 until it can easily accommodate the conduit to be cut. Then, clamp the conduit between the movable jaw 1 and the fixed jaw 2, and rotate the adjusting worm gear 14 to move the movable jaw 1 towards the fixed jaw 2. This clamps and fixes the conduit. During the clamping process, gradually adjust the position of the conduit until the position to be cut on the conduit corresponds to the spring strip 8. Then, rotate the adjusting knob 11 to rotate the adjusting screw 17. This rotates the adjusting screw 17 to move the cutting blade 16 towards the conduit, thus adjusting the position of the cutting blade 16 so that it cuts into the conduit. Simultaneously, rotating the adjusting screw 17 controls the depth to which the cutting blade 16 cuts into the conduit. Then, fix the conduit in place and rotate the entire device around the conduit once using handle 4. During the rotation, the conduit is cut by the cutting blade 16, thus severing the conduit.

[0036] Obviously, the above embodiments of this utility model are merely examples for clearly illustrating this utility model, and are not intended to limit the implementation of this utility model. For those skilled in the art, other variations or modifications can be made based on the above description. It is impossible to exhaustively list all the implementation methods here. Any obvious variations or modifications derived from the technical solutions of this utility model are still within the protection scope of this utility model.
