Description

Technical Field

[0001] This utility model relates to the field of automotive wiring harness clip technology, and in particular to a quick-release clip for automotive wiring harness corrugated tubes. Background Technology

[0002] Automotive wiring harnesses are an important part of automotive circuits and are protected by corrugated tubing to ensure that they are not affected by the external environment. During installation, the corrugated tubing is usually secured with clips to protect it and prevent it from shifting due to vibration or pulling.

[0003] Currently, the existing technology commonly uses rubber clips to fix bellows. During fixing, the bellows is placed inside the clip, and the bellows is fixed by a single-point engagement through the elastic deformation of the male and female clips when the clips are engaged. However, during the use of automobiles, the clips are affected by long-term vibration, and the locking force of the single-point engagement is easily weakened, leading to loosening or falling off, thus affecting the stability of the bellows fixation. Utility Model Content

[0004] Therefore, it is necessary to provide a quick-release buckle for automotive wiring harness corrugated tubes to address the problem that the locking force of single-point snap-fit ​​is easily weakened due to long-term vibration during automotive use, leading to loosening or falling off, which affects the stability of corrugated tube fixation.

[0005] It includes: a first arc-shaped block and a second arc-shaped block, one end of the first arc-shaped block and one end of the second arc-shaped block are hinged together, and a mounting buckle is fixedly connected to the upper surface of the first arc-shaped block; a fixing mechanism, the fixing mechanism including a fixing rod, fixing blocks are fixedly connected to both sides of the bottom end of the fixing rod, two locking blocks are slidably connected to the lower end of the inner wall of the fixing block, a spring is fixedly connected between the opposite ends of the two locking blocks, a connecting block is fixedly connected to the surface of the first arc-shaped block, a mounting block is fixedly connected to the surface of the second arc-shaped block, and a round rod is fixedly connected to one side of the connecting block and one side of the mounting block, and the surface of the round rod has an opening.

[0006] In one embodiment, the fixing mechanism further includes multiple locking rods fixedly connected to the inner surface of the connecting block, and the surface of the mounting block has multiple evenly distributed locking grooves. The overall shape of the connecting block and the overall shape of the mounting block are both "L". When the first arc-shaped block and the second arc-shaped block fix and engage the bellows, it is beneficial to form multi-point positioning to initially limit the first arc-shaped block and the second arc-shaped block.

[0007] In one embodiment, the top opening of the passage is funnel-shaped, and the end of the locking block away from the spring is bent into a spherical shape. This facilitates the automatic compression of the locking block into the fixing block by the inclined surface of the inner wall of the passage opening when the fixing block is inserted into the passage and pressed down, thereby allowing the fixing block to move smoothly downward.

[0008] In one embodiment, the locking rod is inclined on the side away from the connecting block, and the vertical cross-section of the locking groove is a right-angled triangle. This helps to ensure the locking effect between the locking rod and the locking groove.

[0009] In one embodiment, rubber pads are fixedly connected to the inner walls of both the first and second arc-shaped blocks, and the two rubber pads are disposed on the same vertical plane. This helps to enhance the fixing effect on the corrugated pipe.

[0010] In one embodiment, a protruding rod is fixedly connected to the top end of the fixing rod, and the top end of the protruding rod is bent into a spherical shape. This facilitates easier operation of the fixing rod by the worker.

[0011] In one embodiment, the first arc-shaped block, the second arc-shaped block, the mounting buckle, the connecting block, the mounting block, and the locking rod are all rubber components. This ensures the stability of the device during installation.

[0012] In one embodiment, a groove is formed at the lower end of the inner wall of the fixing block, and the surface of the locking block is slidably connected to the inner wall of the groove. This facilitates limiting the movement path of the locking block.

[0013] Beneficial effects 1. When the first arc-shaped block and the second arc-shaped block of the above-mentioned fixing mechanism fix the bellows and engage, the installation block is inserted into the inside of the connecting block and engaged with the slot by multiple locking rods. This helps to form multi-point positioning to initially limit the first arc-shaped block and the second arc-shaped block. Then, the fixing rod, fixing block, locking block and round rod form a locking structure, which helps to fix the relative position of the connecting block and the installation block. This avoids the phenomenon of loose connection and detachment of the positioning point of the connecting block and the installation block during the fixing of the first arc-shaped block and the second arc-shaped block to the bellows, thereby ensuring the stability of the bellows fixing. 2. Under the action of the spring, the upper inclined surface of the inner wall of the slot, and the spherical surface of the end of the locking block, the above-mentioned fixing mechanism is conducive to the automatic squeezing of the locking block into the fixing block when the fixing block is inserted into the through and pressed down. After the fixing block moves into place, the locking block automatically resets and forms a locking engagement with the round rod, which makes the fixing mechanism easier to operate.

[0017] 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, not all, of the embodiments of this utility model. All other embodiments obtained by those skilled in the art based on the embodiments of this utility model without creative effort are within the scope of protection of this utility model.

[0018] The following is combined with Figures 1-5 This invention describes a quick-release clip for a corrugated tube in an automotive wiring harness.

[0019] In one embodiment, a quick-release buckle for an automotive wiring harness corrugated tube includes: a first arc-shaped block 100 and a second arc-shaped block 200, one end of the first arc-shaped block 100 and one end of the second arc-shaped block 200 are hinged together, and an mounting buckle 110 is fixedly connected to the upper surface of the first arc-shaped block 100. The fixing mechanism 300 includes a fixing rod 330. Fixing blocks 331 are fixedly connected to both sides of the bottom end of the fixing rod 330. Two locking blocks 332 are slidably connected to the lower end of the inner wall of the fixing block 331. A spring 333 is fixedly connected between the opposite ends of the two locking blocks 332. A connecting block 310 is fixedly connected to the surface of the first arc-shaped block 100. An mounting block 320 is fixedly connected to the surface of the second arc-shaped block 200. A round rod 340 is fixedly connected to one side of the connecting block 310 and one side of the mounting block 320. An opening 341 is provided on the surface of the round rod 340.

[0020] In this embodiment, when the fixing block 331 enters the through-hole 341, the surface of the fixing block 331 is in contact with the inner wall of the through-hole 341. When the fixing block 331 cannot move further during the insertion into the through-hole 341, the surface of the connection between the fixing rod 330 and the round rod 340 is in contact with the inner wall of the round rod 340. In the initial state, the spring 333 is in the released state, and the opposite ends of the two locking blocks 332 in the fixing block 331 pass through the fixing block 331.

[0021] like Figure 2 and Figure 5 As shown, the fixing mechanism 300 also includes multiple locking rods 311 fixedly connected to the inner surface of the connecting block 310. The surface of the mounting block 320 is provided with multiple evenly distributed slots 321. The overall shape of the connecting block 310 and the overall shape of the mounting block 320 are both "L". The side of the locking rod 311 away from the connecting block 310 is inclined, and the vertical cross-section of the slot 321 is a right triangle.

[0022] In this embodiment, rotating the second arc-shaped block 200 causes one end of the mounting block 320 away from the second arc-shaped block 200 to enter the inner side of the connecting block 310, and when the second arc-shaped block 200 is in contact with the other end of the first arc-shaped block 100, the vertical portion of the mounting block 320 is parallel to the vertical portion of the connecting block 310. (See reference...) Figure 2 At this time, the positions of multiple locking rods 311 correspond one-to-one with the positions of multiple locking slots 321. One end of the inclined surface of the locking rod 311 will enter the corresponding locking slot 321. Meanwhile, the round rod 340 on one side of the connecting block 310 is flush with the round rod 340 on one side of the mounting block 320.

[0023] like Figure 4 As shown, the top opening of the through-hole 341 is flared, and the end of the locking block 332 away from the spring 333 is bent into a spherical shape.

[0024] In this embodiment, when the fixing block 331 is placed into the corresponding opening 341, the spherical surface at the end of the locking block 332 contacts the inclined surface at the opening of the opening 341. Therefore, when the fixing block 331 is pressed to move into the opening 341, the inclined surface at the upper end of the inner wall of the opening 341 will squeeze the locking block 332 to move into the fixing block 331.

[0025] like Figure 2 As shown, rubber pads 350 are fixedly connected to the inner walls of the first arc-shaped block 100 and the second arc-shaped block 200, and the two rubber pads 350 are set on the same vertical plane.

[0026] In this embodiment, when the first arc-shaped block 100 and the second arc-shaped block 200 fix the corrugated pipe, the rubber pad 350 is aligned with one of the recesses on the surface of the corrugated pipe, and after fixing, the rubber pad 350 enters the aligned recess, thereby strengthening the fixing effect on the corrugated pipe.

[0027] like Figure 4 As shown, a protruding rod 334 is fixedly connected to the top of the fixing rod 330, and the top of the protruding rod 334 is bent into a spherical shape.

[0028] In this embodiment, the operator can use the protruding rod 334 to operate the fixed rod 330.

[0029] like Figure 5 As shown, the first arc-shaped block 100, the second arc-shaped block 200, the mounting buckle 110, the connecting block 310, the mounting block 320, and the clamping rod 311 are all rubber components.

[0030] In this embodiment, during the process of rotating the second arc block 200 to engage with the first arc block 100, the connecting block 310 and the mounting block 320 may undergo certain deformation, thereby ensuring that the end of the mounting block 320 away from the second arc block 200 smoothly enters the inner side of the connecting block 310. The mounting buckle 110 is a relatively mature structure in the prior art and will not be described in detail here.

[0031] like Figure 4 As shown, a groove is provided at the lower end of the inner wall of the fixing block 331, and the surface of the locking block 332 is slidably connected to the inner wall of the groove.

[0032] In this embodiment, the spring 333 is disposed in the slide groove, and the two locking blocks 332 in the fixing block 331 can move into the slide groove at the same time and can be completely moved into the slide groove at the same time.

[0033] Working principle: When using this device to fix the corrugated pipe, the mounting buckle 110 is installed in the designated mounting hole. After installation, the corrugated pipe is placed inside the first arc-shaped block 100, and the second arc-shaped block 200 is rotated to engage with the first arc-shaped block 100. During the rotation of the second arc-shaped block 200, the end of the mounting block 320 away from the second arc-shaped block 200 enters the inside of the connecting block 310. When the other end of the second arc-shaped block 200 is in contact with the first arc-shaped block 100, multiple locking rods 311 engage with multiple locking slots 321 one by one, thereby securing the first arc-shaped block 100 and the second arc-shaped block 200. The initial positioning is performed, and the two fixing blocks 331 are respectively placed into the openings 341 corresponding to the two round rods 340. The fixing blocks 331 are pressed into the openings 341 by the fixing rods 330. During the movement, the locking block 332 is squeezed into the fixing block 331, and the spring 333 is compressed. When the fixing block 331 can no longer move downward, the locking block 332 and the spring 333 lose their compression. The locking block 332 automatically resets under the action of the spring 333 and engages with the corresponding round rod 340. At this time, the final fixing of the relative positions of the connecting block 310 and the mounting block 320 is completed, thereby fixing the second arc block 200 and the first arc block 100.

[0034] The above embodiments are only used to illustrate the technical solutions of this utility model, and are not intended to limit it. Although this utility model has been described in detail with reference to the foregoing embodiments, those skilled in the art should understand that modifications can still be made to the technical solutions described in the foregoing embodiments, or equivalent substitutions can be made to some of the technical features. Such modifications or substitutions will not cause the essence of the corresponding technical solutions to deviate from the spirit and scope of the technical solutions of the embodiments of this utility model.
