specific Embodiment approach 1

[0034] Combine below Figure 1-10 Describe this embodiment. The present invention relates to an anti-rear-collision device, more specifically, an anti-rear-collision device for trucks, including a fixed seat 1, a main frame body 2, an anti-collision assembly 3 and a pulley 4. The anti-collision assembly in the present invention When 3 is hit, not only can play the effect of cushioning, and anti-collision component 3 also can move downward when being bumped and moves backward, more effectively prevents low car from rushing into the bottom of the truck when colliding with the rear.

[0035] The main frame body 2 can slide back and forth on the fixed seat 1, the anti-collision assembly 3 can slide vertically at the front end of the main frame body 2, two pulley parts 4 are arranged on the left and right sides, and the two pulley parts 4 are all arranged on the anti-collision Component 3 on.

specific Embodiment approach 2

[0037] Combine below Figure 1-10 To illustrate this embodiment, the anti-collision assembly 3 will move downward relative to the fixed seat 1 while moving backward relative to the fixed seat 1 .

specific Embodiment approach 3

[0039] Combine below Figure 1-10 To illustrate this embodiment, the two pulleys 4 are both slidingly connected to the front end of the main frame body 2 .

Abstract

The invention relates to an anti-rear-end device, in particular to an anti-rear-end device for a truck. The anti-rear-end device for the truck is characterized in that the anti-rear-end device comprises a fixed seat, a main frame body, an anti-collision component and two pulley parts; when the anti-collision is impacted, not only can the anti-collision component act as a buffer, but also the anti-collision component is moved backwards and downward at the same time by the impact, being effective in preventing a low vehicle from rushing into the bottom of the truck; the main frame body can slideback and forth on the fixed seat; the anti-collision component can slide vertically at the front end of the main frame body; the two pulley parts are arranged on the anti-collision component.

Description

technical field [0001] The invention relates to an anti-rear-collision device, in particular to an anti-rear-collision device for trucks. Background technique [0002] The application number is CN201621363161.8, which discloses an anti-rear collision buffer for trucks. This utility model discloses an anti-rear collision buffer for trucks. Buffer springs, secondary buffer springs and buffer locks, the main anti-collision plate, the middle support beam and the rear liner are connected through the telescopic shaft, the telescopic shaft guide sleeve is connected with the middle support beam and the rear liner, the primary buffer spring and the secondary The buffer spring is installed on the telescopic shaft, and the buffer lock is installed between the intermediate support beam and the guide sleeve of the telescopic shaft. The anti-rear-collision buffer for trucks of the utility model can protect the rear-end vehicles at any time, achieve anti-collision effects, reduce casualti...
