Clamping type fixed support

Abstract

The invention discloses a clip-type fixed bracket, which comprises a fixed bracket (1), a movable bracket (2), a cable tie installation plate (3) and a connecting rod mechanism (4), and the fixed bracket (1) includes a top plate ( 11), a riser (12) and a bottom plate (13), the riser (11) is provided with a first waist-shaped hole (14), and the bottom plate (13) is provided with a connecting groove (15) with an opening The cable tie installation plate (3) is arranged on the top of the top plate (11), and the cable tie installation plate (3) is provided with a cable tie installation hole (31); the bottom of the movable support (2) Rotationally installed in the connecting groove (15), the end of the connecting rod mechanism (4) passes through the first waist-shaped hole (14) and connects with the riser (12) through a nut (5) . The invention does not need to be fixed by bolts, does not affect the strength of the vehicle frame, and can adjust the installation position of the bracket, and is suitable for various vehicle frames with different thicknesses.

Description

technical field [0001] The invention relates to a fixing bracket, in particular to a clip-type fixing bracket suitable for fixing pipelines and circuits. Background technique [0002] The "Technical Conditions for Motor Vehicle Operation Safety" stipulates that in the air brake system, the brake pipeline should have appropriate safety protection to avoid scratches, winding or other mechanical damage. Most heavy-duty trucks are fixed with brackets and cable ties. First, the bracket is fixed on the frame with bolts, and then the pipeline is fixed with cable ties to ensure the reliability of pipeline fixing. The pipelines and wiring harnesses on the vehicle are all arranged on the chassis. The pipelines include air pipes, oil pipes, urea pipes, water pipes, etc. Due to the limited space in the chassis, the requirements for the layout of pipes and lines are getting higher and higher. [0003] Such as figure 1 and figure 2 As shown, in the prior art, the bracket 100 is provid...

AI Technical Summary

Problems solved by technology

[0004] The above fixing method has the following disadvantages: (1) This fixing method needs to open a fixing hole on the frame, which affects the overall strength of the frame, and the strength of the opening is weak and easy to crack; (2) The fixing position is suitable for the middle of the frame Up and down, if it is fixed near the lower wing of the frame, it is extremely inconvenient to install cable ties to fix the pipeline, but due to the large number of chassis pipes and lines, some pipelines need to be fixed near the lower wing of the frame according to the layout requirements; ( 3) The fixed position of the pipeline in this fixing method cannot be moved
