Description

Technical Field

[0001] This utility model relates to the field of wire harness fixing bracket technology, specifically a snap-on quick-release wire harness fixing bracket. Background Technology

[0002] In fields such as electrical wiring, automotive manufacturing, aerospace, communication equipment, and industrial machinery, the fixation and management of wire harnesses are crucial. Currently, there are many types of fasteners on the market used to fix wire harnesses to sheet metal holes (mounting holes). A search revealed a utility model patent with patent authorization announcement number CN219779660U, which discloses a quick-fixing wire harness clip, including a fastener and an elastic baffle. The fastener includes a binding strip, connecting strips, and main clips. The binding strip is bent into a circle with an opening. Two connecting strips are fixed to both ends of the binding strip and are arranged parallel to each other. Two main clips are respectively located on opposite sides of the two connecting strips. A notch is also provided on the binding strip. One end of the elastic baffle extends into the circle channel of the binding strip along the notch and is fixed to the binding strip and located close to the opening. The other end of the elastic baffle has an elastic tendency to offset along the notch toward the side of the binding strip opposite to the opening.

[0003] However, existing mounting brackets typically consist of a plastic base and attached clips. During installation, the clips are aligned and pressed into the sheet metal holes, relying on their elastic deformation to achieve a secure connection. However, disassembly often requires pulling or prying with tools, posing a risk of damaging the clips or the sheet metal paint. Furthermore, after repeated disassembly, the clips' elasticity diminishes, leading to insecure fixing and low reusability. Therefore, improvements are needed. Utility Model Content

[0004] The purpose of this utility model is to provide a snap-on quick-release wire harness fixing bracket, which solves the problems of inconvenient disassembly and low reusability of existing snap-on quick-release wire harness fixing brackets.

[0005] To achieve the above objectives, this utility model provides the following technical solution: a snap-on quick-release wire harness fixing bracket, comprising a hollow circular shell, a first plastic sleeve and a second plastic sleeve fixedly connected to the top of the hollow circular shell, a rubber bead fixedly connected to the second plastic sleeve, the rubber bead penetrating the first plastic sleeve and engaging with the first plastic sleeve, a fixing sleeve fixedly connected to the bottom inner side of the hollow circular shell, a rotating sleeve connected to the outer ring wall of the fixing sleeve by a thread, and multiple snaps slidably connected to the bottom of the hollow circular shell, the snaps penetrating the hollow circular shell, each snap being fixedly connected to a sliding pin, the sliding pin penetrating the fixing sleeve and slidably connected to the fixing sleeve, the end of the sliding pin abutting against the inner ring wall of the rotating sleeve.

[0006] Preferably, the first and second plastic sleeves are symmetrically arranged, and both are arc-shaped. The symmetrical arrangement and arc shape of the first and second plastic sleeves facilitate the wrapping of the wire harness.

[0007] Preferably, the bottom of the buckle is integrally formed with a protrusion, and the buckle is made of plastic. The protrusion facilitates the buckle's engagement after passing through the pre-drilled hole in the sheet metal.

[0008] Preferably, the bottom of the hollow circular shell has a groove, and the buckle is located in the groove. The groove facilitates the radial expansion and contraction of the buckle within the hollow circular shell.

[0009] Preferably, the inner wall of the rotating sleeve is provided with a conical surface, and the end of the sliding pin is provided with an arc, the arc end of the sliding pin being slidably connected to the conical surface of the rotating sleeve. Through the cooperation between the arc end of the sliding pin and the conical surface of the rotating sleeve, the sliding pin and the buckle can be subjected to the radial thrust of the hollow circular shell.

[0010] Preferably, a retaining ring is fixedly connected to the pin body of the sliding pin, and a spring is sleeved on the outside of the pin body of the sliding pin. One end of the spring is fixedly connected to the retaining ring, and the other end of the spring is fixedly connected to the inner surface of the fixed sleeve.

[0011] Preferably, the hollow cylindrical shell has two notches on its side wall, and the two notches are symmetrically arranged. The notches facilitate the operation of components such as the screwing and rotating sleeves.

[0012] Compared with the prior art, the beneficial effects of this utility model are as follows:

[0013] 1. This utility model sets a hollow round shell as the main body of the fixing frame, and then sets arc-shaped plastic sleeve one and plastic sleeve two on the hollow round shell to wrap the wire harness. Rubber beads are used to realize the quick snap-fit ​​and separation of the two, which facilitates the fixing and release of the wire harness. The operation is simple and convenient.

[0014] 2. This utility model sets a combination of a fixed sleeve and a rotating sleeve inside a hollow circular shell, and then sets components such as a sliding pin, a buckle, a retaining ring and a spring between the two. The multiple buckles can be driven to extend and retract radially in sync by rotation, so as to achieve a firm engagement or release with the sheet metal hole. Compared with the traditional method of using buckles to engage with the sheet metal hole, it is easier to disassemble. Attached Figure Description

A plastic sleeve 2 and a plastic sleeve 3 are fixedly connected to the top of the hollow circular shell 1. The plastic sleeves 2 and 3 are symmetrically arranged and both are arc-shaped. The symmetrical arrangement and arc shape of the plastic sleeves 2 and 3 facilitates the wrapping of the wire harness. A rubber bead 4 is fixedly connected to the plastic sleeve 3, passing through the plastic sleeve 2 and engaging with it.

[0022] Please see Figure 3 , Figure 4A fixed sleeve 5 is fixedly connected to the inner bottom of the hollow circular shell 1. A rotating sleeve 6 is threadedly connected to the outer wall of the fixed sleeve 5. Multiple buckles 7 are slidably connected to the bottom of the hollow circular shell 1, and the buckles 7 penetrate the hollow circular shell 1. A sliding groove is opened at the bottom of the hollow circular shell 1, and the buckles 7 are located in the sliding groove. The sliding groove facilitates the radial expansion and contraction of the buckles 7 in the hollow circular shell 1. The bottom of the buckles 7 is integrally formed with a protrusion, and the buckles 7 are made of plastic. The protrusion facilitates the snapping of the buckles 7 after passing through the reserved hole in the sheet metal. A sliding pin 8 is fixedly connected to each buckle 7. The sliding pin 8 penetrates the fixed sleeve 5 and is slidably connected to the fixed sleeve 5. The end of the sliding pin 8 abuts against the inner wall of the rotating sleeve 6. The inner wall of the rotating sleeve 6 is provided with a conical surface, and the end of the sliding pin 8 is provided with an arc. The arc end of the sliding pin 8 is slidably connected to the conical surface of the rotating sleeve 6.

The notches 11 facilitate the operation of the rotating sleeve 6 and other components.

[0023] The specific implementation process of this utility model is as follows: First, rotate the rotating sleeve 6. The rotating sleeve 6 moves axially in the fixed sleeve 5. The inner conical surface of the rotating sleeve 6 pushes the arc surface at the end of the sliding pin 8, so that all the sliding pins 8 together with the buckles 7 retract radially inward along the hollow round shell 1. Then, each buckle 7 is inserted into the reserved hole of the sheet metal. Then, rotate the rotating sleeve 6 in reverse. The buckles 7 will be reset under the action of the spring 10. The protrusion at the bottom of the buckle 7 will hook the inner edge of the sheet metal hole to achieve a firm lock. Later, the entire assembly can be quickly and without damage by simply rotating the rotating sleeve 6. Then, place the wire harness between the plastic clip 1 2 and the plastic clip 2 3, and press the rubber bead 4 on the plastic clip 2 3 into and through the clip hole of the plastic clip 1 2 to fix the wire harness.
