Abstract
Description
Technical Field
[0001] This utility model relates to the field of engineering machinery technology, specifically to pipeline fixing devices and engineering machinery. Background Technology
[0002] With the continuous development of automobiles and construction machinery, configurations and functions are constantly being enriched. At the same time, the pipeline layout of vehicle chassis is becoming more and more complex. As the requirements for pipeline precision are getting higher and higher, how to effectively and reliably fix and protect pipelines while ensuring that they do not affect other components, and improve pipeline operation efficiency, has always been a hot topic of discussion in pipeline design.
[0003] Currently, cable ties, cedar-shaped cable ties, and cable tie fixing brackets are used to secure pipelines (wiring harnesses). However, in some areas with limited working space, it is inconvenient to bind and remove excess cable ties. Utility Model Content
[0004] In view of this, the present invention provides a pipeline fixing device and engineering machinery to solve the problem of inconvenience in bundling wire harnesses with cable ties in related technologies.
[0005] In a first aspect, this utility model provides a pipeline fixing device for installation on a walkway of engineering machinery. The pipeline fixing device includes a main body, a clip, and a pipe clip. The pipe clip engages with the main body to fix the wire harness. The clip is connected to the main body and is used to engage with a slot on the walkway to fix the pipeline fixing device to the walkway. The slot has two opposing sidewalls. The clip includes two notched corners and two convex corners, which are distributed at the four corners around the clip. When the clip enters the slot and rotates at a preset angle, the notched corners can pass through the sidewalls. After the clip rotates at the preset angle, the convex corners abut against the sidewalls.
[0006] Beneficial effects: When the clip enters the slot and is rotated, the notched corner passes through the side wall and does not interfere with the platform, allowing the clip to rotate smoothly into place. After the clip has rotated to the preset angle, i.e., when it has rotated to the correct position, the protruding corner abuts against the platform, causing interference and restricting the clip's rotation. The clip engages with the slot, enabling convenient, quick, and accurate installation of the pipeline fixing device on the platform. Even in narrow spaces, blind operation is possible, preventing excessive rotation that could cause the clip to fall off and reducing the probability of installation failure. The cable harness can be quickly fixed by the clip engaging with the main body.
[0007] In one optional embodiment, the distance between two opposite sidewalls of the slot is A, the buckle is rectangular, the distance between the two notched corners is less than A, and the distance between the two convex corners is greater than A.
[0008] In one alternative embodiment, the ends of the two opposite sidewalls of the slot are bent and extended toward each other to form a groove. The buckle is rectangular, the width of the buckle is smaller than the width of the groove opening, and the length of the buckle is greater than the length of the groove opening.
[0009] Beneficial effects: Because the width of the buckle is smaller than the opening of the slot, the buckle can smoothly enter the slot from the opening. After the buckle is rotated to a preset angle, because the length of the buckle is greater than the opening of the slot, the buckle interferes with the walkway plate, and the buckle engages with the slot, reliably confining the buckle in the slot.
[0010] In one alternative embodiment, both of the notched corners are rounded, and both of the convex corners are right angles.
[0011] Beneficial effects: During the process of the clip entering the slot and rotating, the rounded corners do not interfere with the platform, allowing the clip to rotate smoothly into place. Once the clip has rotated to the preset angle and is in place, the right angle interferes with the platform, limiting the clip's rotation, and the clip engages with the slot. Therefore, the pipeline fixing device can be installed on the platform conveniently, quickly, and accurately, even in confined spaces, allowing for blind operation and reducing the probability of installation failure. The cable harness can be quickly secured by the clip engaging with the main body.
[0012] In one optional implementation, the preset angle is 90°.
[0013] Beneficial effect: When the preset angle is 90°, it is easier for the operator to judge whether the rotation is in place, which helps with blind operation.
[0014] In one optional embodiment, the pipeline fixing device further includes: a first elastic component and a second elastic component, the first elastic component being connected to the buckle and the second elastic component being connected to the main body, the first elastic component and the second elastic component being located on both sides of the buckle along its thickness direction, and when the buckle is engaged in the slot, the first elastic component abuts against the bottom wall of the slot and the second elastic component abuts against the outer edge of the slot opening, so that the buckle is engaged with the inner edge of the slot opening.
[0015] Beneficial effects: The first elastic component abuts against the bottom wall of the slot, undergoing elastic deformation and providing a rearward elastic force to the buckle. The second elastic component abuts against the outer edge of the slot opening, also deforming and providing a rearward elastic force to the buckle. Thus, the first and second elastic components ensure the buckle is firmly engaged in the slot, improving the locking stability.
[0016] In one optional embodiment, one end of the tube buckle is connected to the main body, and the other end of the tube buckle is provided with a locking groove; the end of the main body away from the tube buckle is provided with a locking tongue, and when the tube buckle is fastened to the main body, the locking tongue is engaged in the locking groove; or, one end of the tube buckle is connected to the main body, and the other end of the tube buckle is provided with a locking tongue; the end of the main body away from the tube buckle is provided with a locking groove, and when the tube buckle is fastened to the main body, the locking tongue is engaged in the locking groove.
[0017] Beneficial effects: The tube clip and the main body are engaged by the locking tongue and locking groove, which can easily and quickly fix the wire harness.
[0018] In one optional embodiment, the pipeline fixing device further includes a spring clip connected to the inner wall of the pipe buckle. When the pipe buckle is fastened to the main body, both the main body and the spring clip are in contact with the wire harness.
[0019] Beneficial effects: The spring clip clamps the wire harness between the main body and the spring clip through elastic force, improving the stability of the wire harness and preventing the wire harness from shaking and wearing.
[0020] In one optional embodiment, both ends of the spring are connected to the inner wall of the tube buckle, and the spring and the tube buckle together form an annular cavity.
[0021] Beneficial effects: The annular cavity provides clearance for the deformation of the spring, which makes the spring more stable during deformation and improves the reliability of the fixed wire harness.
[0022] In one alternative embodiment, the body, the buckle, and the tube buckle are injection-molded integral parts.
[0023] Beneficial effects: It gives the pipeline fixing device good chemical stability and can improve manufacturing efficiency.
[0024] Secondly, this utility model also provides an engineering machine, including: a walkway plate, the walkway plate being provided with a slot; and a pipeline fixing device as in the first aspect, wherein the buckle is engaged in the slot.
[0025] Beneficial effects: Since construction machinery includes pipeline fixing devices, construction machinery has the same beneficial effects as pipeline fixing devices, which will not be elaborated here. Attached Figure Description

Detailed Implementation
[0035] To make the objectives, technical solutions, and advantages of the embodiments of this utility model clearer, the technical solutions of the embodiments of this utility model will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of this utility model, not all embodiments. Based on the embodiments of this utility model, all other embodiments obtained by those skilled in the art without creative effort are within the protection scope of this utility model.
[0036] Currently, the method of creating openings in the side panels of the walkway of engineering machinery is to provide fixing points for securing cable ties and bundled wire harnesses. Walkway panels are typically made of aluminum, and creating openings increases mold and processing costs, while also reducing the walkway panel's sealing performance. The inner wall of the walkway panel usually has slots for installing decorative panels. A new cable securing device is designed that utilizes these slots and works in conjunction with them to quickly and accurately install the cable securing device onto the walkway panel without requiring additional openings, and also provides quick and convenient securing of wire harnesses.
[0037] The following is combined with Figures 1 to 6 The following describes embodiments of the present invention.
[0038] According to an embodiment of this utility model, in one aspect, a pipeline fixing device 100 is provided, which is used to fix the pipeline fixing device 100 to the walkway 200 of construction machinery. The construction machinery may be a crane, excavator, loader, drilling equipment, etc. The walkway 200 provides a stable working space, avoids personnel directly stepping on equipment parts, and facilitates operation, inspection, or maintenance.
[0039] The pipeline fixing device 100 includes a main body 10, a clip 20, and a pipe clip 30. The pipe clip 30 is fastened to the main body 10 to fix the wire harness L. The clip 20 is connected to the main body 10 and is used to snap into the slot 210 of the platform 200 to fix the pipeline fixing device 100 to the platform 200. The slot 210 has two opposing side walls 211. The clip 20 includes two notched corner portions 21 and two protruding corner portions 22, which are distributed at the four corners of the clip 20's circumference. When the clip 20 enters the slot 210 and rotates at a preset angle, the notched corner portions 21 can pass through the side walls 211 without interfering with the platform 200. After the clip 20 rotates at the preset angle, the protruding corner portions 22 abut against the platform 200, causing interference to limit the rotation of the clip 20, and the clip 20 is engaged with the slot 210.
[0040] The main body 10 is used to engage with the tube clip 30 to clamp and fix the wire harness L. The inner surface of the main body 10 can be adapted to the outer surface of the wire harness L. The inner surface of the tube clip 30 can also be adapted to the outer surface of the wire harness L. For example, the inner surfaces of both the main body 10 and the tube clip 30 can be arc-shaped, forming a ring when the tube clip 30 is engaged with the main body 10 to jointly clamp and fix the wire harness L.
[0041] The clip 20 can be connected to the front side of the main body 10. The clip 20 can enter the slot 210 of the walkway 200, and after being rotated, it is engaged and fixed with the slot 210, thereby fixing the pipeline fixing device 100 to the walkway 200.
[0042] Reference Figure 2The two notched corners 21 are located at one pair of diagonal corners of the four corners of the buckle 20 along the circumference. The two protruding corners 22 are located at the other pair of diagonal corners of the four corners of the buckle 20 along the circumference.
[0043] Reference Figures 3-6 When the latch 20 enters the slot 210 and rotates, the notched portion 21 does not interfere with the platform 200, meaning the notched portion 21 does not obstruct the rotation of the latch 20, allowing it to rotate smoothly. When the latch 20 rotates to a preset angle (e.g., 90°), the protruding portion 22 interferes with the platform 200, for example, with the wall of the slot 210, meaning the protruding portion 22 obstructs the rotation of the latch 20, limiting its rotation. At this point, the latch 20 engages with the slot 210, preventing it from dislodging, and the latch 20 is properly installed. Figure 3 (As shown). The rotation of the clip 20 can rotate the entire pipeline fixing device 100, thereby causing the clip 20 to rotate.
[0044] The preset angle can be 90°, but it is not limited to this; other angles such as 30°, 60°, 70°, or 80° are also possible. When the preset angle is 90°, it is easier for the operator to judge whether the rotation is in place, which helps with blind operation.
[0045] As the buckle 20 enters the slot 210 and rotates, the notched corner 21 does not interfere with the platform 200, allowing the buckle 20 to rotate smoothly into place. After the buckle 20 rotates to the preset angle, i.e., after it has rotated to the correct position, the protruding corner 22 interferes with the platform 200, restricting the rotation of the buckle 20. The buckle 20 engages with the slot 210, enabling the pipeline fixing device 100 to be installed on the platform 200 conveniently, quickly, and accurately. Even in narrow spaces, blind operation can be performed, reducing the probability of installation failure. The cable harness L can be quickly fixed by fastening the pipe clamp 30 to the main body 10.
[0046] Reference Figure 3 The distance between the two opposite sidewalls 211 of the slot 210 is A. The buckle 20 is rectangular. The distance between the two notched corners 21 is less than A, and the distance between the two protruding corners 22 is greater than A.
[0047] In some embodiments, the ends of the two opposing sidewalls 211 of the slot 210 are bent and extended toward each other to form a slot 212. The width of the buckle 20 is smaller than the vertical dimension B of the slot 212 of the slot 210 so that the buckle 20 can enter the slot 210. The length of the buckle 20 is greater than the vertical dimension B of the slot 212 of the slot 210 so that when the buckle 20 enters the slot 210 and rotates at a preset angle, it interferes with the platform plate 200 so that the buckle 20 engages with the slot 210.
[0048] The width of buckle 20 is the dimension along the left-right direction as shown in the diagram. The length of buckle 20 is the dimension along the up-down direction as shown in the diagram.
[0049] Because the width of the latch 20 is smaller than the opening 212 of the slot 210, for example, when both ends of the latch 20 in the length direction are on the same horizontal plane, the latch 20 can smoothly enter the slot 210 from the opening. After the latch 20 is rotated 90° ( Figure 3 As shown, the two ends of the buckle 20 in the length direction are on the same vertical plane. Since the length of the buckle 20 is greater than the opening of the slot 210, the buckle 20 interferes with the walkway plate 200. The buckle 20 is engaged with the slot 210, which restricts the buckle 20 in the slot 210.
[0050] It is understandable that the buckle 20 entering the slot 210 with its two ends in the same horizontal plane in the length direction is only an example and does not mean that it must enter the slot 210 in this posture.
[0051] In some embodiments, both notched corners 21 are rounded, and both convex corners 22 are right angles.
[0052] Compared to the right angle of the convex corner 22, the rounded corner of the notched corner 21 is a missing part. In other words, the right angle of the convex corner 22 is a protruding part compared to the rounded corner of the notched corner 21. For example, one pair of opposite corners can be cut off from the original four right angles of the buckle 20 to form two rounded corners of the notched corner 21.
[0053] As the clip 20 enters the slot 210 and rotates, the rounded corner does not interfere with the platform plate 200, allowing the clip 20 to rotate smoothly into place. After the clip 20 rotates to the preset angle, i.e., after it has reached the correct position, the right angle interferes with the platform plate 200, restricting the rotation of the clip 20, and the clip 20 engages with the slot 210. Therefore, the pipeline fixing device 100 can be conveniently, quickly, and accurately installed on the platform plate 200, even in confined spaces, allowing for blind operation and reducing the probability of installation failure. The cable harness L can be quickly fixed by the clip 30 engaging with the main body 10.
[0054] In some embodiments, refer to Figure 1 and Figure 3 The pipeline fixing device 100 also includes a first elastic component 41 and a second elastic component 42. The first elastic component 41 is connected to the buckle 20, and the second elastic component 42 is connected to the main body 10. The first elastic component 41 and the second elastic component 42 are respectively located on both sides of the buckle 20 along its thickness direction. When the buckle 20 is engaged in the slot 210, the first elastic component 41 abuts against the bottom wall of the slot 210, and the second elastic component 42 abuts against the outer edge of the slot 210, so that the buckle 20 is engaged with the inner edge of the slot 210.
[0055] The buckle 20 is aligned with its length along its thickness direction as shown in the figure. A first elastic member 41 can be attached to the front side of the buckle 20. A receiving space is formed between the first elastic member 41 and the second elastic member 42 to receive the edge of the slot 210.
[0056] The first elastic member 41 abuts against the bottom wall of the slot 210, and undergoes elastic deformation, providing a rearward elastic force to the buckle 20. The second elastic member 42 abuts against the outer edge of the slot 210, and undergoes deformation, also providing a rearward elastic force to the buckle 20. Thus, the first elastic member 41 and the second elastic member 42 tightly engage the buckle 20 in the slot 210.
[0057] In some embodiments, one end of the tube buckle 30 is connected to the main body 10, and the other end of the tube buckle 30 is provided with a locking groove 31; the end of the main body 10 away from the tube buckle 30 is provided with a locking tongue 11, and when the tube buckle 30 and the main body 10 are fastened together, the locking tongue 11 is engaged in the locking groove 31. In other embodiments, one end of the tube buckle 30 is connected to the main body 10, and the other end of the tube buckle 30 is provided with a locking tongue 11; the end of the main body 10 away from the tube buckle 30 is provided with a locking groove 31, and when the tube buckle 30 and the main body 10 are fastened together, the locking tongue 11 is engaged in the locking groove 31.
[0058] The tube buckle 30 is flexibly connected to the main body 10. The tube buckle 30 rotates toward the main body 10 about the connection point between the tube buckle 30 and the main body 10, thereby engaging the locking tongue 11 and the locking groove 31. This allows for convenient and quick fixation of the wire harness L.
[0059] In some embodiments, the pipeline fixing device 100 further includes a spring piece 50, which is connected to the inner wall of the pipe buckle 30. When the pipe buckle 30 is fastened to the body 10, both the body 10 and the spring piece 50 are in contact with the wire harness L.
[0060] The spring 50 clamps the wire harness L between the main body 10 and the spring 50 through elastic force, thereby improving the stability of the wire harness L and preventing the wire harness L from loosening.
[0061] In some embodiments, both ends of the spring piece 50 are connected to the inner wall of the tube buckle 30, and the spring piece 50 and the tube buckle 30 together form an annular cavity.
[0062] The annular cavity provides clearance for the deformation of the spring 50, which makes the spring 50 have good stability during deformation and improves the reliability of the fixed wire harness L.
[0063] In some embodiments, the body 10, the buckle 20, and the tube buckle 30 are injection-molded integral parts. The injection-molded integral parts can be plastic parts.
[0064] This gives the pipeline fixing device 100 good chemical stability and improves manufacturing efficiency.
[0065] According to an embodiment of this utility model, another aspect provides an engineering machine, including a walkway 200 and a pipeline fixing device 100. The engineering machine can be a crane, excavator, etc. The walkway 200 is provided with a slot 210, and a buckle 20 is engaged in the slot 210.
[0066] The slot 210 can be a decorative slot 210 on the inner side of the walkway 200. The slot 210 can be used to quickly and accurately install the pipeline fixing device on the walkway 200 without the need to drill additional holes in the walkway 200, and can also quickly and conveniently fix the wire harness L.
[0067] Although embodiments of the present invention have been described in conjunction with the accompanying drawings, those skilled in the art can make various modifications and variations without departing from the spirit and scope of the present invention, and such modifications and variations all fall within the scope defined by the appended claims.
