Description

Technical Field

[0001] This utility model relates to the field of wiring harness bracket technology, specifically a lightweight engine wiring harness bracket with a built-in pressure-resistant structure. Background Technology

[0002] A wiring harness bracket generally includes a support part and a bracket body. The support part is mainly used to support the bracket body, while the bracket body is used in conjunction with wire clamps, wire clips, clamps, cable ties, etc. to fix the wiring harness, thereby achieving the purpose of fixing the position and routing direction of the wiring harness. However, there are still some problems with the use of existing engine wiring harness brackets.

[0003] An existing wire harness bracket, wire clip, and connection structure for the wire harness bracket are described in Chinese patent application number CN201922278007.0. The structure includes: a bracket body with a first fixing hole group, a second fixing hole group, and a fixing round hole; the first fixing hole group is used to cooperate with cable ties to fix the wire harness; the second fixing hole group is used to cooperate with cable ties to fix the wire harness, or to cooperate with clamps to fix the wire harness; the fixing round hole is used to cooperate with wire clips to fix the wire harness; and a support part connects to and supports the bracket body. However, existing wire harness brackets have relatively poor stability in fixing cables, cannot avoid cable compression, and have inconvenient overall installation angle adjustment.

[0004] Therefore, we propose a lightweight engine wiring harness bracket with a built-in pressure-resistant structure to solve the problems mentioned above. Utility Model Content

[0005] The purpose of this invention is to provide a lightweight engine wiring harness bracket with a built-in anti-compression structure to solve the problems mentioned in the background art, such as poor cable fixing stability and inability to avoid cable compression.

[0006] To achieve the above objectives, this utility model provides the following technical solution: a lightweight engine wiring harness bracket with a built-in pressure-resistant structure, including a positioning bracket:

[0007] The positioning bracket is connected to a movable bracket at the rear, and a limit block is provided at the front end of the movable bracket. A fixed block is provided in front of the limit block, and a limit screw passes through the middle of the fixed block. A positioning sleeve is fixed to the front of the movable bracket.

[0008] The positioning bracket has a limiting shaft running through its rear side, and the limiting shaft runs through the movable bracket. The outer wall of the limiting shaft is connected to a limiting plate, and a limiting groove is provided at the lower right end of the movable bracket.

[0009] Preferably, the positioning bracket has first through holes on both sides, and a first screw passes through the first through hole; the movable bracket has a second through hole at the upper end, and a second screw passes through the second through hole.

[0010] By adopting the above technical solution, the positioning bracket and the movable bracket can be fixed respectively through the cooperation of the first screw and the second screw, so as to achieve reliable fixation and support of the wire harness.

[0011] Preferably, the limiting blocks are symmetrically fixed on the left and right sides of the movable bracket, and the opposite sides of the limiting blocks and the fixed blocks are provided with semi-circular grooves, and the opposite sides of the limiting blocks and the fixed blocks are connected with rubber pads.

[0012] Using the above technical solution, the semi-circular grooves opened on the opposite sides of the limiting block and the fixing block can facilitate the clamping and positioning of the wire harness. The semi-circular grooves are easy to match with the wire harness protective tube, and the rubber pads can improve the clamping stability.

[0013] Preferably, the front end of the limiting block extends into the interior of the fixed block, and the limiting block and the fixed block are slidably connected. The limiting screw is rotatably connected to the fixed block, and the limiting screw is symmetrically distributed on the upper and lower sides of the fixed block. The rear end of the limiting screw is threadedly connected to the positioning sleeve.

[0014] By adopting the above technical solution, the positioning sleeve of the limiting screw can easily fix the position of the limiting block and the fixing block, and can avoid the wire harness bracket from being squeezed and deformed. The sliding fit between the limiting block and the fixing block can improve the clamping stability.

[0015] Preferably, the lower end of the movable bracket engages with the rear side of the positioning bracket, and the middle part of the limiting shaft passes through the lower end of the movable bracket. The movable bracket, the limiting shaft, and the positioning bracket constitute a rotating structure.

[0016] Using the above technical solution, the positioning bracket and the movable bracket can be rotated through the limiting shaft, and the angle between the movable bracket and the positioning bracket can be adjusted during installation, making it suitable for different installation scenarios.

[0017] Preferably, the limiting plate is slidably connected to the positioning bracket, and the left side of the limiting plate extends into the limiting groove. The left side of the limiting shaft is threaded. The left side of the positioning bracket is rotatably connected to the positioning nut, and the positioning nut is threadedly connected to the limiting shaft. A return spring is sleeved on the outside of the limiting plate, and the left and right sides of the return spring are respectively connected to the inner wall of the positioning bracket and the limiting shaft.

[0018] By adopting the above technical solution, the rotation between the limiting shaft and the positioning bracket can be restricted through the sliding cooperation between the limiting plate and the positioning bracket. After the limiting plate extends into the limiting groove, the angle change of the movable bracket can be restricted, thereby fixing the angle between the movable bracket and the positioning bracket. When the positioning nut is disconnected from the limiting shaft, a return spring can push the limiting plate to disengage from the limiting groove.

[0019] Compared with the prior art, the beneficial effects of this utility model are: the lightweight engine wiring harness bracket with built-in pressure-resistant structure;

[0020] 1. By setting an adjustable clamping structure, reliable clamping and positioning of cables or external protective tubes can be achieved.

[0021] 2. The design features a rotatable bracket structure that allows for angle adjustment, adapting to complex and varied engine compartment installation environments and improving applicability. Combined with a uniquely designed locking mechanism, it can precisely fix the bracket angle, and its flexible and simple operation enhances ease of use. Attached Figure Description

The positioning bracket 1 is initially installed and positioned with the engine or other related components through the first through holes on both sides using the first screw 2, ensuring the accurate position of the positioning bracket 1 to meet the requirements of the engine wiring harness arrangement, and the angle of the movable bracket 3 can be adjusted as needed. After the second screw 9 passes through the second through hole, it is connected to the engine and tightened. When fixing the cable, the limiting block 4 and the fixing block 6 can be used to clamp and fix the wire harness, and can also shield the wire harness. It can withstand the external forces such as vibration and impact generated when the engine is working, protect the engine wire harness from damage, and ensure the normal operation of the wire harness and the stability of signal transmission. The weight reduction holes opened on the surface of the positioning bracket 1 and the movable bracket 3 reduce the overall weight of the bracket without affecting its compressive strength.
