[0046] It should be noted that, unless there is any conflict, the embodiments and features in the embodiments of this application can be combined with each other.

[0047] like Figure 1-8 As shown, the main structure of the wire fixing protection device provided in the embodiment of the present application includes a cable tie 100 and a protective part 200, wherein the cable tie 100 includes a belt body 110 and a tightening part 120, one end of the belt body 110 is connected to the tightening part 120, and the tightening part 120 is configured to allow the free end of the belt body 110 to pass through to tighten the bundled object; the protective part 200 is connected to the tightening part 120, and a protective hole 210 is opened on the protective part 200, and the protective hole 210 is configured to be sleeved on the screw 800.

[0048] The wire protection device of this embodiment is designed to solve the problem of interference and cutting between screws 800 and electrical cables 900 during the assembly of equipment such as air conditioners, thereby improving the reliability and safety of the equipment. The main structure of the wire protection device includes a cable tie 100 and a protection part 200.

[0049] The main components of the cable tie 100 are a belt body 110 and a tightening portion 120. One end of the cable tie 100 is fixedly connected to the tightening portion 120, and the other end is a free end for the operator to use when bundling the cables 900. The tightening portion 120 is designed as an adjustable locking device, which can wrap the free end of the belt body 110 around the electrical circuit and adjust it to the appropriate tightness, thereby effectively bundling the wiring. The tightening portion 120 ensures that the free end of the belt body 110 can be stably fixed after passing through it through the provided notches or other positioning designs. The specific locking method of the tightening portion 120 on the belt body 110 can refer to the existing technology and will not be elaborated on. The material of the belt body 110 can be a durable material such as flexible plastic or nylon, which can withstand long-term tension and use. The length and width of the belt body 110 are determined according to the wiring requirements of the equipment and can adapt to cables 900 of different specifications.

[0050] During the assembly process of the air conditioning unit, operators need to route the electrical wiring within the casing 700. To do this, they first use a cable tie 100 to bundle the tangled electrical cables 900. By passing the free end of the tie 110 through the tightening portion 120 and adjusting it to the appropriate tightness, the cable tie 100 effectively tightens and secures the electrical wiring. The protective holes 210 on the protective portion 200 fit over the pre-installed screws 800 on the casing 700—specifically, they fit over the tip and threaded section of the screws 800. This design effectively prevents interference between the screws 800 and the wiring, ensuring that the screws 800 and the wiring do not collide or cut. During this process, the protective portion 200 not only isolates the screws 800 from the electrical wiring but also, by working with the screws 800, provides additional securement of the wiring, preventing it from shaking or loosening within the device and ensuring the stability and safety of the wiring within the device.

[0051] The wire securing protection device provided in this embodiment effectively solves the problem of screw 800 cutting wires due to interference between cables 900 and screws 800 during the assembly of equipment such as air conditioning units. The bundling action of the cable tie 100 effectively secures the wiring and frees up space within the housing 700. The protective portion 200, by fitting over the screw 800, creates a physical barrier, ensuring that the wiring does not collide with the screw 800 and avoiding the occurrence of wire cutting issues. The protective portion 200 also further secures the wiring and reduces the shaking of the wiring within the unit, thereby improving the safety and reliability of the equipment.

[0052] In some embodiments, as Figure 1 As shown, the protective portion 200 is a columnar structure, the cable tie 100 is arranged at one axial end of the protective portion 200, and the protective hole 210 includes a first protective hole 211 opened at the other axial end of the protective portion 200 and extending along the axial direction of the protective portion 200.

[0053] The protective portion 200 utilizes a columnar structure, offering enhanced adaptability and stability. In this embodiment, the columnar shape of the protective portion 200 facilitates insertion into the fixing holes of the housing 700. This allows the protective portion 200 to assist in securing the wiring even without screws 800, through the coordination of the columnar structure and the hole structure. This design is particularly suitable for areas of the housing 700 where screws 800 are absent, providing additional support and preventing the cable 800 from swaying or becoming loose, thereby enhancing flexibility during assembly.

[0054] Another notable feature of the protective part 200 is the axial extension design of the first protective hole 211. The first protective hole 211 extends along the axial direction of the protective part 200, which can effectively increase the length of the first protective hole 211, improve the contact area when in contact with the screw 800, and ensure that during the wiring process inside the machine, the physical isolation between the screw 800 and the electrical cable 900 is more stable. By increasing the length of the first protective hole 211, the protective part 200 can provide a stronger supporting force between the screw 800 and the line, ensuring the stability of the line inside the machine, avoiding the shaking and loosening of the cable 900, and effectively improving the long-term operation stability and safety of the equipment. For reference, use scenarios in which the columnar protective part 200 is used to cooperate with the fixing hole on the housing 700, or the first protective hole 211 is used to cooperate with the screw 800 on the housing 700. Figure 8 The fixed line protection device in the lower right center.

[0055] In some embodiments, as Figure 1-5 and Figure 7 As shown, the outer surface of the protective portion 200 is provided with a plurality of first latching portions 220 distributed along its axial direction. The first latching portions 220 are protrusions circumferentially surrounding the protective portion 200. The purpose of providing the first latching portions 220 is to improve the fixing effect between the protective portion 200 and the fixing hole after the columnar protective portion 200 is inserted into the fixing hole, thereby preventing the fixing portion from falling out of the fixing hole. Specifically, the protruding structure of the first latching portion 220 will be squeezed and deformed when the protective portion 200 is inserted into the fixing hole, thereby firmly fixing the connection between the protective portion 200 and the fixing hole.

[0056] Preferably, Figure 4 As shown, the side of the first retaining portion 220 facing the cable tie 100 is a first flat surface 221 perpendicular to the axial direction of the guard portion 200, while the side of the first retaining portion 220 facing away from the cable tie 100 is an inclined second flat surface 222. As the second flat surface 222 extends radially outward from the guard portion 200, it gradually approaches the first flat surface 221, forming a wedge-shaped surface. During insertion of the guard portion 200 into the fixing hole, the wedge-shaped design of the second flat surface 222 facilitates smooth insertion of the guard portion 200, while the first flat surface 221 effectively prevents the guard portion 200 from falling out of the hole. The wedge-shaped design of the second flat surface 222 makes insertion of the guard portion 200 smoother, reduces installation resistance, and improves installation efficiency. The flat structure of the first flat surface 221 also effectively locks the guard portion 200 in place, preventing loosening due to vibration, external force, or prolonged use, ensuring a secure fit.

[0057] In some embodiments, as Figure 1-7As shown, the protective portion 200 is provided with a plurality of cracks 230 along the circumferential direction, each of the cracks 230 extends from the free end of the protective portion 200 along the axial direction of the protective portion 200, and each of the cracks 230 radially penetrates to the first protective hole 211, and these cracks 230 divide the protective portion 200 into a plurality of petal-like structures in the circumferential direction.

[0058] The design of the crack 230 enables the protective part 200 to have sufficient elastic deformation ability, so that the protective part 200 can elastically deform according to actual conditions during the installation process, adapt to fixing holes or screws 800 of different sizes, improve the fault tolerance of the installation, and avoid the problem of loose fixation caused by hole diameter mismatch or installation error.

[0059] For example, when the protective portion 200 is inserted into the fixing hole, it is squeezed by the hole wall and deforms radially inward, thereby strengthening the connection between the protective portion 200 and the fixing hole and preventing the protective portion 200 from falling off or loosening. This design improves the adaptability of the installation, and even if there is a certain error in the size of the fixing hole, the protective portion 200 can still be securely fixed.

[0060] For another example, when the first protective hole 211 of the protective part 200 is fitted over the screw 800 pre-installed in the machine, the protective part 200 is squeezed by the screw 800 and deforms radially outward. This radial outward deformation allows the protective part 200 to better contact the screw 800. The radial deformation enhances the friction between the contact surface of the protective part 200 and the screw 800, improving the connection between the protective part 200 and the screw 800. This design not only effectively isolates the cable 900 from direct contact with the screw 800, avoiding the problem of cutting the wire, but also ensures a tight connection between the protective part 200 and the screw 800, thereby improving the stability of the device.

[0061] In some embodiments, as Figure 1 As shown, the wall surface of the first protective hole 211 is provided with a plurality of second stop portions 240 distributed along its axial direction, and the second stop portions 240 are circumferentially arranged protrusions. The protrusion structure of the second stop portions 240 cooperates with the crack 230 structure of the protective part 200 to provide a more stable connection after the protective part 200 is inserted into the screw 800. When the first protective hole 211 of the protective part 200 is sleeved on the screw 800, the screw 800 cooperates with the second stop portions 240 to form a stronger physical contact between the protective part 200 and the screw 800, thereby enhancing the friction and connection stability between the protective part 200 and the screw 800, preventing the protective part 200 from falling off due to vibration or external force, thereby maintaining effective isolation between the screw 800 and the cable 900 and avoiding the risk of the screw 800 cutting the cable.

[0062] In some embodiments, as Figure 1 、 Figure 3-5 and Figure 7 As shown, the protective hole 210 also includes a second protective hole 212 formed on the circumferential surface of the protective portion 200 and extending radially along the protective portion 200. The first protective hole 211 and the second protective hole 212 can respectively form a protective effect in two directions, thereby enhancing the adaptability of the wire fixing protective device. Specifically, the first protective hole 211 extends along the axial direction of the protective portion 200 and is configured to be sleeved on the screw 800 along the axial direction of the protective portion 200, completely enclosing the tip and threaded section of the screw 800 to prevent direct contact between the screw 800 and the wiring. During installation, it is suitable for situations where the exposed end of the screw 800 is perpendicular to the wiring. The second protective hole 212 extends along the radial direction of the protective portion 200 and is formed on the circumferential surface of the protective portion 200. It is configured to be sleeved on the screw 800 along the radial direction of the protective portion 200, laterally enclosing the screw 800. During installation, it is suitable for situations where the exposed end of the screw 800 is parallel to the wiring. Reference scenario for using the second protection hole 212 to cooperate with the screw 800 on the housing 700 Figure 8 The fixed line protection device in the upper left center.

[0063] The user can choose to use the first protective hole 211 or the second protective hole 212 based on the specific positional relationship between the screw 800 and the wiring inside the body. When the screw 800 is arranged generally parallel to the wiring direction, the second protective hole 212 of the protective part 200 can be selected to be mounted on the screw 800 for protection; when the screw 800 is arranged generally perpendicular to the wiring, the first protective hole 211 can be selected to be mounted on the screw 800 for protection. The combined design of the first protective hole 211 and the second protective hole 212 can respectively adapt to the different arrangements of the screw 800 and the wiring, significantly improving the scope of application of the wire fixing protection device. The user can quickly select the appropriate protective hole 210 according to the actual installation environment, reducing the adjustment steps during the assembly process and improving assembly efficiency.

[0064] In some embodiments, the second protective hole 212 of the wire fixing protection device passes through the protection part 200 in the radial direction of the protection part 200, that is, the second protective hole 212 is formed with openings at both radial ends of the protection part 200. This embodiment further optimizes the adaptability of the wire fixing protection device and proposes a design of a second protective hole 212 that passes through the protection part 200 in the radial direction to enhance the flexibility of the device in different installation environments, allowing users to complete the installation more conveniently. In this embodiment, the protection part 200 is still a columnar structure, but compared to the aforementioned embodiment, the second protective hole 212 passes through the protection part 200 in the radial direction, so that it forms openings at both radial ends of the protection part 200, allowing the user to select the end opening closer to the screw 800 for sleeve connection according to the spatial position, thereby improving the convenience of installation. When the screw 800 is roughly perpendicular to the wiring, the first protective hole 211 is used for axial sleeve installation, and the screw 800 is completely wrapped in the protection part 200. When screw 800 is roughly parallel to the wiring, the second protective hole 212 is used for radial installation, and the end opening closer to screw 800 is selected for installation. The user is not restricted to a single direction and can choose the most convenient end for installation based on the spatial layout. This is suitable for situations where the position of screw 800 and cable 900 is limited, especially in a small space, and improves the compatibility of the device.

[0065] In some embodiments, as Figure 3-4As shown, the wall of the second protective hole 212 is provided with a plurality of ridges 250 spaced apart along the circumference of the second protective hole 212. The ridges 250 extend axially along the second protective hole 212. The spaced ridges 250 are deformed after being squeezed by the screw 800, thereby improving the connection between the screw 800 and the protective portion 200. In the previous embodiment, a plurality of second retaining portions 240 distributed along the axial direction are provided on the wall surface of the first protective hole 211, and the second retaining portions 240 are circumferentially arranged protrusions. The interference effect between the circumferentially arranged protrusions and the threads of the screw 800 is too strong, and the resistance during the assembly process is very large, which is not conducive to assembly. However, since a plurality of cracks 230 are circumferentially distributed in the first protective hole 211, when the first protective hole 211 is sleeved on the screw 800, the circumferential protective portion 200 of the first protective hole 211 will deform outward, which can balance the obstructive effect of the protruding structure of the second retaining portion 240. With the help of the synergistic effect of the second retaining portion 240 and the crack 230, the assembly process of the first protective hole 211 and the screw 800 can be made easier while obtaining sufficient connection firmness. However, in this embodiment, since the second protective hole 212 is radially opened on the cylindrical protective portion 200, a structure similar to the slit 230 cannot be provided around the second protective hole 212. Otherwise, the strength of the protective portion 200 cannot be guaranteed. This results in the protective portion 200 having a weak deformation ability around the second protective hole 212. If a circumferential protrusion is further provided on the wall surface of the second protective hole 212, it will cause excessive interference with the threads of the screw 800, resulting in greater assembly resistance. Therefore, the ridge 250 in this embodiment extends along the axial direction of the second protective hole 212 (i.e., the radial direction of the protective portion 200). When the second protective hole 212 is fitted onto the screw 800, the ridge 250 extending along the axial direction of the second protective hole 212 helps reduce resistance during the assembly process. Moreover, the deformation of the ridge 250 after being squeezed can increase the connection strength between the screw 800 and the protective portion 200.

[0066] This embodiment addresses the assembly resistance issue of the second protective hole 212 by providing an axially distributed ridge 250 structure, which cleverly avoids the problem of the crack 230 structure being unsuitable for the second protective hole 212. Furthermore, it can simultaneously reduce assembly resistance and enhance the fixing effect of the screw 800.

[0067] In order to adapt to different installation environments, the connection method between the cable tie 100 and the protective part 200 in the wire protection device needs to have a certain degree of flexibility. For example, when the position or direction of the screw 800 is different, the second protective hole 212 on the protective part 200 needs to adjust its direction to better fit on the screw 800. Based on this, in some embodiments, such as Figure 1-8As shown, the wire-fixing protective device further includes a first connector 300 connected to the cable tie 100 and a second connector 400 connected to the protective portion 200. The first connector 300 and the second connector 400 are rotatably engaged. The first connector 300 is provided with a first locking member 310, and the second connector 400 is provided with a second locking member 410. The wire-fixing protective device has a locked state and an unlocked state. In the locked state, the first locking member 310 and the second locking member 410 are locked and engaged to restrict relative rotation between the first connector 300 and the second connector 400. In the unlocked state, the first locking member 310 and the second locking member 410 are unlocked, allowing the first connector 300 and the second connector 400 to rotate relative to each other. This embodiment allows the cable tie 100 and the protective portion 200 to rotatably engage with each other and has the function of being lockable and unlockable, making it convenient for users to adjust the orientation of the protective portion 200 according to actual installation requirements.

[0068] The rotational axis of the rotational engagement formed between the first connector 300 and the second connector 400 is preferably parallel to the axial direction of the guard portion 200, facilitating angle adjustment of the second guard hole 212 on the guard portion 200. The first locking member 310 provided on the first connector 300 and the second locking member 410 provided on the second connector 400 can be locked or unlocked with each other, thereby restricting or allowing relative rotation between the first connector 300 and the second connector 400. The wire securing device can switch between two states. In the locked state, the first locking member 310 and the second locking member 410 lock together, preventing relative rotation between the first connector 300 and the second connector 400, thereby fixing the angle of the guard portion 200. This is suitable for situations where a stable connection is required after the orientation of the guard portion 200 is determined. In the unlocked state, the first locking member 310 and the second locking member 410 are released, allowing the first connector 300 and the second connector 400 to rotate freely relative to each other. The user can adjust the orientation of the second guard hole 212 on the guard portion 200 to accommodate screws 800 of different orientations.

[0069] This embodiment provides a more flexible cable securing and protection device through the rotational connection between the cable tie 100 and the protection portion 200, combined with a lockable / unlockable design. This design allows the user to freely adjust the orientation of the second protection hole 212 during installation to accommodate screws 800 in different orientations, improving installation flexibility and ease of use.

[0070] In some embodiments, the first connector 300 and the second connector 400 are both cylindrical sleeve structures. The second connector 400 is coaxially sleeved on the outside of the first connector 300. The second locking members 410 are locking holes circumferentially distributed on the second connector 400, and the first locking members 310 are locking protrusions protruding from the outer wall of the first connector 300. The first connector 300 is made of a material with a certain degree of elasticity, such as plastic or rubber. During use, pressing the locking protrusion can cause the first connector 300 to deform and concave toward the center. After releasing the locking protrusion, the first connector 300 drives the locking protrusion to rebound and return to its original position.

[0071] The wire protection device adopts a coaxial cylindrical sleeve structure, combined with an elastic locking mechanism, and uses the cooperation of the locking protrusion and the locking hole to achieve convenient rotation adjustment and locking functions, ensuring that the connection between the cable tie 100 and the protective part 200 can be rotated and adjusted, and can be stably locked in the set position. The first connecting member 300 is made of elastic material, which gives it deformable properties. During the unlocking process, the user presses the locking protrusion, causing the first connecting member 300 to deform concavely toward the center, thereby disengaging the locking protrusion from the locking hole and allowing the second connecting member 400 to rotate relative to it. During the locking process, after releasing the pressure, the first connecting member 300 automatically rebounds due to the elasticity of the material, causing the locking protrusion to re-embed into the locking hole, thereby completing the locking.

[0072] By pressing the locking tab, the user can freely rotate and adjust the angle of the guard 200, adapting the orientation of the screw 800 to different installation environments. The push-to-unlock and release-to-lock design allows for easy adjustment and securement without the need for additional tools. The coaxial sleeve structure ensures smooth rotation and prevents loosening, balancing stability and ease of operation for an enhanced user experience.

[0073] In some embodiments, the first connector 300 is provided with hollow portions 320, located on either side of the locking protrusion. In the design of a rotationally adjustable wire guard, convenient unlocking is crucial. This embodiment, by providing hollow portions 320 on either side of the locking protrusion of the first connector 300, further reduces the operating force required to unlock the lock, facilitating smoother rotational adjustment.

[0074] The shape and size of the hollow portion 320 can be optimized based on material properties and deformation requirements. Common forms include elongated strips, ovals, or other open-hole structures. Because the hollow portions 320 are provided on either side of the locking protrusion, the portion of the first connector 300 where the locking protrusion resides is more susceptible to deformation when pressed, becoming more likely to concave toward the center, allowing the locking protrusion to disengage from the locking hole, thereby smoothly unlocking the device and reducing the force required to press and unlock.

[0075] In some embodiments, as Figure 1-8 As shown, a shielding sheet 500 is provided between the protective portion 200 and the second connecting member 400. The shielding sheet 500 is arranged perpendicular to the axial direction of the protective portion 200. When the protective portion 200 is inserted into the fixing hole or the first protective hole 211 is fitted over the screw 800, the shielding sheet 500 is parallel to the housing in which the fixing hole or screw 800 is provided. At this time, the shielding sheet 500 can separate the cable fixed by the cable tie 100 from other screws 800 or metal structures on the housing 700, thereby preventing problems such as wear, short circuits, or electromagnetic interference caused by contact. Preferably, the shielding sheet 500 forms a cutting portion 510 on one side of the second protective hole 212 where the opening is provided. The cutting portion 510 is flush with the outer edge of the second connecting member 400. The provision of the second cutting portion 510 ensures that when the second protective hole 212 is fitted over the screw 800, the shielding sheet 500 will not interfere with the housing 700 and will not affect the fitting of the second protective hole 212 over the screw 800.
