Description

Technical Field

[0001] This invention relates to the field of wire harness technology, and more specifically, to an easy-installing and limiting wire harness and its usage method. Background Technology

[0002] Wiring harness tubes are widely used in instruments and meters, and are commonly used on the outside of automotive wiring harnesses to protect them.

[0003] For ease of installation and maintenance, existing wire harness conduits typically have an opening of the same length and connected to the inside of the conduit on one side. This opening is usually closed during and after installation. When installing the conduit onto the outside of the wire harness, the opening needs to be opened and the wires inserted sequentially. During this process, the conduit undergoes elastic deformation, and the resulting elastic force causes the opening to close. If the opening at the wire harness insertion point is not kept open, the wires can be scratched by the conduit wall, shortening the overall lifespan of the wire harness and increasing the risk of short circuits later. Furthermore, constantly prying open the conduit opening is physically demanding and carries the risk of injury to the operator's fingers. Therefore, a new structure is needed to address the time-consuming and laborious installation process of some traditional wire harness conduits.

[0004] Therefore, a new solution is needed to address this problem. Summary of the Invention

[0005] In view of the shortcomings of the existing technology, the purpose of this invention is to provide an easy-to-install limiting wire harness tube and its usage method.

[0006] The above-mentioned technical objective of the present invention is achieved through the following technical solution: the easy-to-install limiting wire harness tube includes a tube body, a first opening with the same length as the tube body and communicating with its inner side is provided on the side wall of the tube body, an inner tube with the same length as the tube body is sleeved inside the tube body, a second opening with the same length as the inner tube and communicating with its inner side is provided on the side wall of the inner tube, the second opening can be rotated with the inner tube to be aligned with or deviated from the first opening, an auxiliary component is detachably connected to the inner tube, when the first opening and the second opening are aligned, the auxiliary component can slide along the inner side of the inner tube from one end to the other end in the length direction of the inner tube.

[0007] The present invention is further configured such that: the auxiliary component includes a tubular component whose outer wall abuts against the inner wall of the inner tube, and a third opening with the same length as the tubular component and communicating with its inner side is provided on the side wall of the tubular component; when the auxiliary component slides in the inner tube, the third opening is located on the side away from the second opening.

[0008] The invention is further configured such that: a lever perpendicular to the tubular member is fixedly connected to the outer wall of the tubular member on the side away from the third opening, and one end of the lever extends out of the tube through the second opening and the first opening.

[0009] The invention is further configured such that: a pull ring is fixedly connected to the actuating rod and is perpendicular to it and faces the outer wall of the tubular component; the actuating rod is located at one end of the tubular component along its length; symmetrical actuating inclined surfaces are arranged on the actuating rod near the opening of the tubular component, with the length direction consistent with the actuating inclined surfaces; the width direction of the actuating inclined surfaces is spliced ​​together on one side; and a clearance groove is provided on the tubular component for the wire harness to be wound to the rear side of the actuating inclined surface.

[0010] The invention is further configured such that: a guide rod of the same length as the inner wall of the inner tube facing the second opening is fixedly connected, the guide rod including a narrow section that abuts against the tubular parts on both sides of the third opening and a wide section that passes through the third opening into the interior of the tubular parts.

[0011] The present invention is further configured such that: both sides of the third opening near one end of the lever are provided with rounded corners, and a guide groove is provided between the two rounded corners.

[0012] The invention is further configured such that: a guide plate with the same length direction as the outer wall of the tubular member on the side opposite to the third opening is fixedly connected, and the distance from the top of the guide plate to the tubular member is less than or equal to the wall thickness of the inner tube.

[0013] The present invention is further configured such that: both sides of the inner tube along its length are fixedly connected with limiting ring pieces that protrude from the tube body and abut against both ends of the tube body; the outer wall of the inner tube abuts against the inner wall of the tube body; a fourth opening is provided on one side of each limiting ring piece, which communicates with its inner side and with the second opening; and symmetrically arranged guide slopes are provided at the fourth opening on the end face of the limiting ring piece.

[0014] The present invention is further configured as follows: a method for using the easy-installing limiting wire harness tube, for use of the aforementioned easy-installing limiting wire harness tube, includes, Step 1: Insert the wire harness into the tubular component using the rounded corners, guide grooves, and third opening, ensuring that the tubular component is fitted on the outside of the wire harness. Pull the wire harness and slide it inside the tubular component so that one side of the wire harness along its length is close to the lever. At the same time, wrap one end of the wire harness into the relief groove. Step 2: Insert the tubular part with the wire harness into the limiting ring and the inner tube. During this process, the guide rod is inserted into the tubular part by means of the rounded corners and the guide groove. At the same time, under the action of the actuating slope and the guide slope on the actuating rod, the actuating rod opens the fourth opening, the second opening and the first opening and inserts into the first opening and the second opening. Step 3: Using the pull ring, slide the actuating rod, tubular component, and wire harness from one end of the tube to the other along the length of the tube, and pull the tubular component until the actuating rod passes through the limiting ring and abuts against the limiting ring. Step 4: Use the pull ring and the lever to rotate the tubular component. The interlocking of the guide rod and the tubular component, as well as the interlocking of the guide plate and the second opening, causes the tubular component to rotate the inner tube relative to the tube body. The rotation of the tube body causes the second opening to deviate from the first opening. Step 5: Remove the tubular component from the inner tube and the wire harness.

[0015] In summary, the present invention has the following beneficial effects: The second opening can rotate with the inner tube to be aligned with or offset from the first opening. When the second opening is aligned with the first opening, both the first and second openings can be opened simultaneously, allowing the wire harness to be stably fed into the inner tube through both openings. This allows the inner tube and tube body to stably cover the outside of the wire harness, thus enabling the inner and outer tubes to stably cover and protect the wire harness. When the second opening is offset from the first opening, the first and second openings are misaligned. The inner wall of the tube body can then block the second opening, and the inner tube wall can block the first opening, achieving stable positioning of the wire harness and reducing the possibility of the wire harness sliding out of the inner tube and tube body from the first and second openings. This ensures that the tube body and inner tube can stably cover and protect the wire harness. Attached Figure Description

[0018] The present invention will now be described in detail with reference to the accompanying drawings and embodiments.

[0019] This easy-to-install limiting wire harness tube, such as Figures 1-4 As shown, the device includes a corrugated tube 1. A first opening 2, of the same length as the tube and communicating with its inner side, is formed on the side wall of the tube 1. This first opening 2 allows the user to provide space when fitting the tube 1 onto the wire harness, ensuring the tube 1 can be stably fitted onto the outside of the wire harness, thus providing stable protection. An inner tube 3 of the same length is fitted inside the tube 1, providing stable coverage and protection for the wire harness, thus achieving double-layer protection for the wire harness. Stable protection is provided so that even if the tube body 1 is accidentally damaged, the inner tube 3 will continue to protect the wire harness, ensuring that the overall structure of the wire harness and its functions are more stable. The inner tube 3 has a second opening 4 on its side wall that is the same length as the inner tube and communicates with the inner side. The second opening 4 is used to provide space for the wire harness to pass through the inner tube 3, thereby ensuring that the wire harness can be stably passed into the inner tube 3 and stably protected by the inner tube 3. The inner tube 3 is a straight tube, which ensures that the wire harness can slide better in the inner tube 3, making the wire harness installation process more convenient and faster. like Figures 2-4As shown, the second opening 4 can rotate with the inner tube 3 to be directly opposite or offset from the first opening 2. When the second opening 4 is directly opposite the first opening 2, both the first and second openings 2 and 4 can be opened simultaneously, allowing the wire harness to be stably fed into the inner tube 3 through the first and second openings 2 and 4. This allows the inner tube 3 and tube body 1 to stably cover the outside of the wire harness, thus enabling the inner and outer tubes to stably cover and protect the wire harness. When the second opening 4 is offset from the first opening 2, the first and second openings 2 and 4 are misaligned. The inner wall of tube body 1 can be used to block the second opening 4, and the inner tube 3 can be used to block the first opening 2, achieving stable positioning of the wire harness and reducing the possibility of the wire harness sliding out of the inner tube 3 and tube body 1 from the first and second openings 2 and 4. To ensure that the tube body 1 and inner tube 3 can stably cover and protect the wire harness, an auxiliary component is detachably connected to the inner tube 3. When the first opening 2 and the second opening 4 are aligned, the auxiliary component can slide along the inner side of the inner tube 3 from one end to the other along the length of the inner tube 3. The auxiliary component helps to stably guide and limit the wire harness as it is inserted into the inner tube 3 and outer tube, thus providing stable assistance for the installation of the wire harness with the inner tube 3 and tube body 1. This simplifies the installation process and provides stable protection for the wire harness, reducing damage during installation and improving the stability and service life of the wire harness. The auxiliary component is designed to be detachable, allowing it to be removed after installation, reducing its impact on subsequent use of the wire harness.

[0020] like Figures 2-4 As shown, the auxiliary component includes a tubular member 5 whose outer wall abuts against the inner wall of the inner tube 3. This arrangement allows the inner wall of the inner tube 3 to stably limit the movement of the tubular member 5, thereby ensuring greater stability during the sliding process of the tubular member 5 and the auxiliary component as a whole along the inner tube 3 and the tube body 1. This ensures that the auxiliary component can better guide the wire harness into the inner tube 3 and the tube body 1. A third opening 6, with the same length as the tubular member 5 and communicating with its inner side, is provided on the side wall of the tubular member 5. The third opening 6 provides a stable clearance during the wire harness insertion into the tubular member 5, thereby allowing the wire harness to be stably inserted into the tubular member 5, making the tubular member 5 more stable. The component 5 can stably limit the wire harness, thereby allowing the auxiliary component to stably drive the wire harness into the inner tube 3 and the tube body 1. When the auxiliary component slides in the inner tube 3, the third opening 6 is located on the side away from the second opening 4. This setting can achieve a stable limiting effect on the wire harness in the tubular component 5 by blocking the third opening 6 at the inner wall of the inner tube 3 during the auxiliary component's wire harness installation process. This makes the state of the wire harness in the tubular component 5 more stable, thereby allowing the tubular component 5 to better achieve stable limiting of the wire harness, and allowing the auxiliary component to better drive the wire harness into the tube body 1 and the inner tube 3.

[0021] like Figure 2 , Figure 3 , Figure 4 , Figure 7 and Figure 8 As shown, a lever 7 perpendicular to the tubular component 5 is fixedly connected to the outer wall of the tubular component 5 on the side away from the third opening 6 by welding. Both the tubular component 5 and the lever 7 are made of stainless steel. The high structural strength and stability of stainless steel ensure that both the tubular component 5 and the lever 7 have good and stable structural strength, ensuring that the tubular component 5 and the lever 7 remain stable during the installation of the auxiliary wiring harness, making the installation of the auxiliary component and the overall auxiliary wiring harness more convenient and faster. One end of the lever 7 extends out of the tube 1 through the second opening 4 and the first opening 2. A pull ring 8 perpendicular to the lever 7 and facing the outer wall of the tubular component 5 is fixedly connected to the lever 7 by welding. The pull ring 8 allows the user to better apply force to the lever 7, thereby applying force to the tubular component 5, making the installation of the auxiliary component and the overall auxiliary wiring harness more convenient. The lever 7 is located at one end of the tubular component 5 along its length. This setting ensures that the tubular component 5 and the lever 7 have good structural strength and stability, ensuring that the tubular component 5 and the lever 7 remain stable during the installation of the auxiliary component and the overall auxiliary wiring harness. During the insertion of the tubular component 5 into the inner tube 3, the actuating rod 7 can penetrate into the first opening 2 and the second opening 4 earlier, thereby pushing the first opening 2 and the second opening 4 to open, thus providing clearance for the wire harness installation process. This ensures that the auxiliary component can stably drive the wire harness to be installed in the inner tube 3 and the tube body 1. The actuating rod 7 near the opening of the tubular component 5 is symmetrically provided with actuating inclined surfaces 9 in the same length direction. The width direction of the actuating inclined surfaces 9 is spliced ​​together on one side. The tubular component 5 is provided with a clearance groove 10 for the wire harness to be wound around to the back of the actuating inclined surface 9. With the help of the actuating inclined surface 9, the actuating rod 7 can better penetrate into the first opening 2 and the second opening 4 and push the first opening 2 and the second opening 4 to open, so that the wire harness can be inserted into the inner tube 3 through the opened first opening 2 and the second opening 4, thus achieving stable installation of the wire harness. With the help of the clearance groove 10, the wire harness can be stably shielded and protected by the actuating rod 7 during installation, making the installation process of the wire harness more stable.

[0022] like Figures 2-6As shown, a guide rod 11 of the same length is integrally formed on the inner wall of the inner tube 3 opposite the second opening 4. The guide rod 11 includes a narrow section that abuts against the tubular parts 5 on both sides of the third opening 6 and a wide section that passes through the third opening 6 into the interior of the tubular parts 5. The cross-sectional shape of the guide rod 11 along the width direction is a combination of a circle and a rectangle, with the circular section being the wide section and the rectangular section being the narrow section. With the help of the guide rod 11, the tubular parts 5 can be stably guided and limited during the sliding process in the inner tube 3, and the rotation process of the tubular parts 5 can be limited. This ensures that after the tubular parts 5 are inserted into the inner tube 3 and the guide rod 11, they can only slide along the length direction of the inner tube 3, making the sliding process of the tubular parts 5 smoother and more stable. This, in turn, ensures that the auxiliary component can better drive the wire harness to be installed in the inner tube 3.

[0023] like Figures 2-4 As shown, rounded corners 12 are provided on both sides of the third opening 6 near the end of the lever 7, and a guide groove 13 is provided between the two rounded corners 12. With the help of the formed guide groove 13 and rounded corners 12, the process of the wire harness being inserted into the tubular component 5 can be stably guided. At the same time, it can also reduce the wear of the wire harness during the process of the wire harness being inserted into the tubular component 5, making the process of the wire harness being inserted into the tubular component 5 more stable and smooth, so that the auxiliary component as a whole can better assist the wire harness in installation.

[0024] like Figures 2-4 As shown, a guide plate 14 with the same length direction is fixedly connected to the outer wall of the tubular component 5 on the side opposite to the third opening 6 by welding. The distance from the top of the guide plate 14 to the tubular component 5 is less than or equal to the wall thickness of the inner tube 3. By inserting the guide plate 14 into the second opening 4 and sliding it in the second opening 4, the overall sliding process of the tubular component 5 and the auxiliary component can be stably guided and limited, further ensuring that the sliding process of the auxiliary component relative to the inner tube 3 is more stable and smooth. At the same time, when the lever 7 slides out of the first opening 2 and the second opening 4, when the auxiliary component drives the inner tube 3 to rotate, the contact area between the guide plate 14 and the second opening 4 can increase the contact area between the auxiliary component and the inner tube 3, so that the auxiliary component can better drive the inner tube 3 to rotate relative to the outer tube, so that the first opening 2 and the second opening 4 can be offset, thereby achieving stable limiting of the wire harness installed in the inner tube 3.

[0025] like Figures 2-4As shown, both sides of the inner tube 3 along its length are fixedly connected by welding to limiting rings 15 that protrude from the tube body 1 and abut against both ends of the tube body 1. The outer wall of the inner tube 3 abuts against the inner wall of the tube body 1. The limiting rings 15 can stably restrict the position of the tube body 1 and the inner tube 3, and stably limit the sliding process of the inner tube 3 along the length of the tube body 1. This prevents the inner tube 3 from sliding arbitrarily when installing the wire harness, and allows the auxiliary component to better install the wire harness inside the inner tube 3. One side of each limiting ring 15 has a hole that communicates with its inner side and is connected to... The fourth opening 16, which is connected to the second opening 4, is provided with symmetrically arranged guide slopes 17 on the end face of the limiting ring 15. The fourth opening 16 is used to stably pass the wire harness and auxiliary parts over the limiting ring 15. With the help of the guide slopes 17, when the push slope 9 is against it, the fourth opening 16 can be better pushed to open, thereby driving the first opening 2 and the second opening 4 to open. This makes it easier for the auxiliary parts to pass into the inner tube 3 and the tube body 1, and makes it easier for the auxiliary parts to drive the wire harness installation process.

[0026] The usage method of this easy-to-install limiting wire harness tube is as follows: Figures 1-8 As shown, the use of the aforementioned easy-installation limiting wire harness tube includes, Step 1: Insert the wire harness into the tubular component 5 using the rounded corner 12, guide groove 13 and third opening 6, ensuring that the tubular component 5 is fitted on the outside of the wire harness. Pull the wire harness to slide it inside the tubular component 5 so that one side of the wire harness in the length direction is close to the lever 7, and at the same time wrap one end of the wire harness into the relief groove 10. Step 2: Insert the tubular part 5 with wire harness into the limiting ring piece 15 and the inner tube 3. During this process, with the help of the rounded corner 12 and the guide groove 13, the guide rod 11 is inserted into the tubular part 5. At the same time, under the action of the actuating inclined surface 9 and the guide inclined surface 17 on the actuating rod 7, the actuating rod 7 opens the fourth opening 16, the second opening 4 and the first opening 2 and inserts into the first opening 2 and the second opening 4. Step 3: Using the pull ring 8, the actuating rod 7, the tubular part 5 and the wire harness slide from one end of the tube body 1 to the other end along the length direction. Pull the tubular part 5 to the position where the actuating rod 7 passes through the limiting ring 15 and abuts against the limiting ring 15. Step 4: The tubular component 5 is rotated by the pull ring 8 and the lever 7. The guide rod 11 and the tubular component 5 are engaged with each other, and the guide plate 14 and the second opening 4 are engaged with each other, so that the tubular component drives the inner tube 3 to rotate relative to the tube body 1. The rotation of the tube body 1 causes the second opening 4 to deviate from the first opening 2. Step 5: Remove the tubular component 5 from the inner tube 3 and the wire harness component.

All technical solutions falling within the scope of the present invention's concept are within the scope of protection of the present invention.
