The application number is CN202021667794.4, and the application date is August 12, 2020. This patent provides a wire harness fixing device and an automotive wire harness fixing structure. The device includes: a clamping component, which includes an openable retaining ring for fixing the wire harness; a piston assembly, which includes a piston body and a hydraulic cylinder, the piston body being fixedly connected to the clamping component via a connecting rod; the piston body is disposed within the hydraulic cylinder, dividing the cylinder into a first hydraulic chamber and a second hydraulic chamber, the first hydraulic chamber including a first oil passage hole, and the second hydraulic chamber including a second oil passage hole; the hydraulic cylinder also includes an oil guide pipe connecting the first and second oil passage holes; and a switching component, disposed at the position of the second oil passage hole to open or close the second oil passage hole. In this design, when the vehicle or wire harness vibrates, the position of the piston changes according to the force applied to the retaining ring. Therefore, there is no need to reserve a long buffer harness section between stationary and moving parts of the vehicle body. The internal wiring harness occupies little space and will not affect surrounding parts.

[0003] When existing wire harnesses are arranged in large quantities in a fixed space, they need to be classified and organized to ensure their orderliness. Therefore, this paper aims to propose a modular fixing device for rail transit wire harnesses, which can adjust the position of the wire harness fixing components in a fixed space to classify and fix the wire harnesses in an orderly manner. Utility Model Content

[0005] To achieve the above objectives, this utility model is implemented through the following technical solution:

[0006] A modular fixing device for rail transit wire harnesses includes a fixing platform with crisscrossing sliding rails. Several wire harness fixing components are arranged within the sliding rails. Each wire harness fixing component includes an I-shaped base with clamp components for fixing the wire harness rotatably connected to the base.

[0007] As a preferred embodiment, the base includes a bottom plate disposed in a groove on the lower surface of the fixed platform, a vertical rod connected to the upper surface of the bottom plate, a top plate integrally disposed on the free end of the vertical rod, the vertical rod being disposed within the sliding track, and the top plate being disposed in contact with the upper surface of the fixed platform.

[0008] As a preferred embodiment, the base plate is provided with a connecting seat, the connecting seat has an internal thread, the lower free end of the vertical rod is provided with an external thread, and the vertical rod is screwed into the connecting seat.

[0009] As a preferred embodiment, the top plate is integrally provided with an extension plate, and a positioning bolt is screwed into the extension plate, with the free end face of the positioning bolt abutting against the upper surface of the fixed platform.

[0010] As a preferred embodiment, the clamp assembly includes an upper clamp body and a lower clamp body that are hinged together, and a rod body that is integrally welded to the bottom of the lower clamp body and rotatably connected to the base.

[0011] Compared with the prior art, the beneficial effects of this utility model are: by distributing the wire harness fixing components in the crisscrossing sliding tracks, the wire harness fixing components can be placed in the corresponding horizontal or vertical positions in the sliding tracks according to the position of the wire harness, so as to organize and classify the wire harness in an orderly manner. It is suitable for industrial production and has strong practicality. Attached Figure Description

[0015] The technical solution of this application will be further described below with reference to the accompanying drawings and embodiments.

[0016] like Figure 1-2As shown, a modular fixing device for rail transit wire harnesses includes a fixing platform 1 with crisscrossing sliding rails 2. Several wire harness fixing components 3 are arranged within the sliding rails 2. Each wire harness fixing component 3 includes an I-shaped base 4, with clamping components 5 rotatably connected to the base 4 for fixing the wire harness. The base 4 includes a bottom plate 6 located within a groove on the lower surface of the fixing platform 1, such that the lower surface of the bottom plate 6 is flush with the lower surface of the fixing platform 1. A vertical rod 7 is connected to the upper surface of the bottom plate 6, and a top plate 8 is integrally formed on the free end of the vertical rod 7. The vertical rod 7 is located within the sliding rails 2, and the top plate 8 is fitted against the upper surface of the fixing platform 1. A connecting seat 9 is provided on the bottom plate 6, with internal threads inside. External threads are provided on the lower free end of the vertical rod 7, and the vertical rod 7 is screwed into the connecting seat 9. An extension plate 10 is integrally provided on the edge of the top plate 8. A positioning bolt 11 is screwed into the extension plate 10, and the free end face of the positioning bolt 11 abuts against the upper surface of the fixed platform 1. The clamp assembly 5 includes an upper clamp body 501 and a lower clamp body 502 that are hinged together. A rod body 503 that is rotatably connected to the base 4 is integrally welded to the bottom of the lower clamp body 502.

[0017] During operation, the operator can arbitrarily select the position of the wire harness fixing component 3 within the sliding rail 2, setting it to be in the same horizontal or vertical position as the wire harness to be fixed. Then, the positioning bolt 11 is screwed into the extension plate 10 and abuts against the surface of the fixing platform 1. The position of the wire harness fixing component 3 is fixed by the action of friction. The wire harness is then wrapped with a clamp to complete the fixing of the wire harness. The rod 503 of the clamp component 5 can be set as a telescopic rod, so that the height of the clamp component 5 can be adjusted to avoid interference between wire harnesses in the same plane direction.

[0018] This utility model is not limited to the above embodiments.
