Description

Technical Field

[0001] This utility model relates to the field of air conditioner wiring harness cutting technology, specifically a household air conditioner wiring harness cutting device. Background Technology

[0002] Air conditioner wiring harnesses are used to connect various electrical components inside the air conditioner and transmit power and signals. The quality of the wiring harness directly affects the installation and operational stability of the air conditioner.

[0003] A patent with publication number CN202322546731.3 discloses a cutting mechanism for inverter air conditioner wiring harnesses. It sets a wiring harness groove on one side of the base, installs a detachable wiring harness block on the wiring harness groove, and opens a wiring harness groove on the wiring harness block. The wiring harness groove is coaxial with the wiring harness groove on the base and has the same diameter as the wiring harness to be cut. Since the wiring harness block can be replaced to adapt to the diameter of the wiring harness by removing and installing two screws, the cutting mechanism can dynamically maintain the flatness of the cut when cutting wiring harnesses of different specifications and sizes.

[0004] However, in the above-mentioned technical solutions, the cable tray and the base are relatively fixed, making it difficult to accommodate air conditioning cable harnesses of different diameters, resulting in poor adaptability of the cable tray to the diameter of the air conditioning cable harnesses. Therefore, the present invention aims to provide a household air conditioning cable harness cutting device that can adapt to various air conditioning cable harness diameters. Utility Model Content

[0005] To address the shortcomings of existing technologies, this utility model provides a household air conditioner wiring harness cutting device that can adapt to various air conditioner wiring harness diameters, thus solving the problem that existing wire troughs are difficult to adapt to various air conditioner wiring harness diameters.

[0006] To achieve the above objectives, this utility model provides a household air conditioner wiring harness cutting device, including a base having a first sidewall and a second sidewall opposite to each other, a fixing block being installed on the first sidewall; a clamping block being disposed on the top of the fixing block and spaced apart from the first sidewall to form a wiring groove; a rotating column being rotatably disposed on the second sidewall, with a bracket fixed to the end of the rotating column and a cutting blade being installed on the bracket; and a tightening component being disposed between the clamping block and the rotating column, wherein when the rotating column rotates clockwise or counterclockwise, the clamping block moves closer to or further away from the first sidewall through the tightening component to increase or decrease the width of the wiring groove.

[0007] Optionally, the tightening component includes a tightening rope and a slider; a sliding groove is provided on the top of the fixing block, the slider is fixed to the bottom of the clamping block, and the slider is slidably disposed in the sliding groove; a movable opening is provided on the base to connect the first side wall and the second side wall, the tightening rope is movably disposed in the movable opening, and the tightening rope is elastic; the first end of the tightening rope is fixed on the rotating column, and the second end of the tightening rope is fixed on the clamping block.

[0008] Optionally, the side of the clamping block closest to the first sidewall has an arc-shaped structure.

[0009] Optionally, the first sidewall has an arc-shaped structure.

[0010] Optionally, the base is provided with a plurality of adjustment slots spaced apart along its height direction. The adjustment slots are adapted for the movable insertion of the adjustment column. The end of the adjustment column is fixed with a stop block, which is located below the cutting blade.

[0011] Optionally, the top of the abutment block has an arc-shaped structure, and a knife-draining groove is provided on the abutment block, the knife-draining groove being adapted to allow at least part of the cutting knife to move in and out.

[0012] Compared with the prior art, this utility model provides a household air conditioner wiring harness cutting device, which has the following beneficial effects:

[0013] This invention incorporates a tightening component. When the rotating column rotates forward, the tightening component simultaneously moves the clamping block closer to the first sidewall, thereby reducing the width of the entire wire trough. After the cutting operation is completed, the bracket is released, the rotating column is reversed, and the tightening component releases the clamping block, moving it appropriately away from the first sidewall, thus increasing the width of the entire wire trough and facilitating the removal of the cut wire harness body.

[0014] By setting a cutting blade, this utility model allows the adjusting post to be inserted into a lower position for wire harnesses with larger diameters, ensuring that the abutment block can provide sufficient support under the cutting blade. Similarly, for wire harnesses with smaller diameters, the adjusting post can be inserted into a higher position.

[0015] By setting a slotted cutting tool, the cutting tool can freely enter and exit the slotted cutting tool during the cutting process, and only cuts the wire harness body without interfering with other components, thus avoiding unnecessary lateral movement of the cutting tool and reducing wear on the cutting tool.

[0023] 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.

[0024] Example: Please refer to Figures 1 to 6 According to an embodiment of the present invention, a technical solution is provided: a household air conditioner wiring harness cutting device, including a base 1 having a first sidewall and a second sidewall opposite to each other, a fixing block 2 installed on the first sidewall; a clamping block 3 disposed on the top of the fixing block 2 and spaced apart from the first sidewall to form a wiring groove 4; a rotating column 5 rotatably disposed on the second sidewall, a bracket 6 fixed at the end of the rotating column 5, and a cutting blade 7 installed on the bracket 6; and a tightening component disposed between the clamping block 3 and the rotating column 5, wherein when the rotating column 5 rotates forward or backward, the clamping block 3 moves closer to or further away from the first sidewall through the tightening component to increase or decrease the width of the wiring groove 4.

[0025] In the household air conditioner wiring harness cutting device with the above structure, when the user needs to cut the wiring harness body 16, firstly, the wiring harness body 16 to be processed is placed between the clamping block 3 and the first side wall, so that the wiring harness body 16 is within the wire groove 4. Next, the bracket 6 is held and rotated, causing the rotating column 5 to rotate clockwise. At this time, the cutting blade 7 fixed on the bracket 6 moves accordingly and gradually comes into contact with the wiring harness body 16. As the cutting blade 7 approaches the wiring harness body 16, the tightening component simultaneously moves the clamping block 3 closer to the first side wall to reduce the width of the wire groove 4, ensuring that the wiring harness body 16 is firmly clamped during the cutting process, while preventing the wiring harness body 16 from sliding or shifting during the cutting process. After the cutting operation is completed, the bracket 6 is released, the rotating column 5 is reversed, so that the cutting blade 7 returns to its initial position. At the same time, the tightening component releases the clamping block 3, moving it appropriately away from the first side wall, thereby increasing the width of the wire groove 4, making it easier to remove the cut wiring harness body 16.

[0026] In this embodiment, the tightening component includes a tightening rope 8 and a slider 9; a sliding groove 10 is provided on the top of the fixing block 2, and the slider 9 is fixed to the bottom of the clamping block 3 and slidably disposed in the sliding groove 10; a movable opening 11 is provided on the base 1 to connect the first side wall and the second side wall, and the tightening rope 8 is movably disposed in the movable opening 11. The tightening rope 8 is elastic; the first end of the tightening rope 8 is fixed to the rotating column 5, and the second end of the tightening rope 8 is fixed to the clamping block 3; when the user rotates the bracket 6, causing the rotating column 5 to rotate clockwise, the first end of the tightening rope 8 is wound up by the rotating column 5, causing the second end of the tightening rope 8 to move the clamping block 3, and the movement of the clamping block 3 will cause the slider 9 to move in the sliding groove 10, thereby causing the clamping block 3 to move closer to the first side wall. At this time, the width of the entire wire groove 4 gradually decreases, ensuring that the wire harness body 16 is firmly clamped. After the cutting operation is completed, the user releases the bracket 6, and the rotating column 5 automatically reverses due to the elasticity of the tightening rope 8, thereby gradually loosening the tightening rope 8. During this process, the tightening rope 8 will gradually release the clamping block 3, allowing it to move away from the first side wall, thereby increasing the width of the wire groove 4 and making it easier to remove the cut wire harness body 16.

[0027] In this embodiment, the side of the clamping block 3 closest to the first sidewall has an arc-shaped structure; the arc-shaped surface allows the clamping block 3 to better cover the wire harness, providing a more stable clamping effect.

[0028] In this embodiment, the first sidewall has an arc-shaped structure; the arc-shaped surface allows the first sidewall to better cover the wire harness, providing a more stable clamping effect.

[0029] In this embodiment, the base 1 has several adjustment slots 12 spaced apart along its height direction. The adjustment slots 12 are suitable for the movable insertion of the adjustment post 13. The end of the adjustment post 13 is fixed with a wire abutment block 14, which is located below the cutting blade 7. With this configuration, by adjusting the insertion height of the adjustment post 13, the height of the wire abutment block 14 is adjusted, thereby supporting the wire harness body 16 against the cutting blade 7 within its optimal cutting range. This allows the cutting blade 7 to accommodate wire harness bodies 16 of different diameters. For wire harness bodies 16 with larger diameters, the adjustment post 13 can be inserted at a lower position to ensure that the wire abutment block 14 can provide sufficient support force below the cutting blade 7. Similarly, for wire harness bodies 16 with smaller diameters, the adjustment post 13 can be inserted at a higher position.

[0030] In this embodiment, the top of the abutment block 14 has an arc-shaped structure, and a cutter groove 15 is provided on the abutment block 14. The cutter groove 15 is suitable for at least part of the cutting blade 7 to move in and out. With this configuration, the arc-shaped structure at the top of the abutment block 14 can better fit the shape of the wire harness body 16, providing a uniform pressure distribution. At the same time, the cutting blade 7 can freely move in and out of the cutter groove 15 during the cutting process, and only cuts the wire harness body 16 without interfering with other components, avoiding unnecessary lateral movement of the cutting blade 7 and reducing wear on the cutting blade 7.

[0031] Working principle: When the user needs to cut the wire harness body 16, firstly, the wire harness body 16 to be processed is placed between the clamping block 3 and the first side wall, so that the wire harness body 16 is in the wire groove 4. Next, the user holds the bracket 6 and rotates it, causing the rotating column 5 to rotate clockwise. The first end of the tightening rope 8 is then wound up by the rotating column 5, causing the second end of the tightening rope 8 to move the clamping block 3. The movement of the clamping block 3 will cause the slider 9 to move within the sliding groove 10, thereby bringing the clamping block 3 closer to the first side wall. At this time, the width of the wire groove 4 gradually decreases, ensuring that the wire harness body 16 is firmly clamped. After the cutting operation is completed, the user releases the bracket 6. The rotating column 5 automatically reverses due to the elasticity of the tightening rope 8, thereby gradually loosening the tightening rope 8. During this process, the tightening rope 8 gradually releases the clamping block 3, allowing it to move away from the first sidewall, thereby increasing the width of the entire wire groove 4 and facilitating the removal of the cut wire harness body 16. By adjusting the insertion height of the adjusting post 13, the height of the abutment block 14 is adjusted, thereby supporting the wire harness body 16 within the optimal cutting range of the cutting blade 7, enabling the cutting blade 7 to accommodate wire harness bodies 16 of different diameters. For wire harness bodies 16 with larger diameters, the adjusting post 13 can be inserted at a lower position to ensure that the abutment block 14 can provide sufficient support force below the cutting blade 7. Similarly, for wire harness bodies 16 with smaller diameters, the adjusting post 13 can be inserted at a higher position.

[0032] 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.
