Automobile door block made by bamboo for boxcar

Abstract

The invention relates to a bamboo car door shield used for a box car, and particularly relates to a car door shield used for preventing the car door from being pressed by goods when the goods are loaded on the box car. The car door shield structurally comprises a door shield upper cross beam, a door shield lower cross beam, door shield upright columns, a left side tightening diagonal drawing piece and a right side tightening diagonal drawing piece. The door shield upper cross beam and the door shield lower cross beam are respectively located on an upper side and a lower side; a group of door shield upright columns are arranged at the middle part; and each door shield upright column is vertically mounted between the door shield upper cross beam and the door shield lower cross beam. Round holes are drilled at the junctions of the upper and the lower cross beams and the columns, and hard bamboo wedges are adopted for fixing; the left side tightening diagonal drawing piece and the right side tightening diagonal drawing piece are mounted on the left and the right sides between the door shield upper cross beam and the door shield lower cross beam. The bamboo car door shield is adopted for preventing the car door from being pressed by goods when the goods are loaded. The structure of the bamboo car door shield for the box car in railroad transportation is used in railway transportation, and has the characteristics of sturdiness, durability, smooth circumference, little possibility of deformation, strong elasticity, good anti-collision performance and safety in use.

Description

technical field [0001] The invention relates to a car door stopper used to protect the car door from being squeezed and expanded when the box car is loaded with goods, in particular to a bamboo car door stopper. technical background [0002] In railway freight, many important goods will be shipped with boxcars, because the doors on the left and right sides of boxcars need to be opened alternately on different platforms to complete the task of loading or unloading. Like this, when loading goods on one side, the car door on the other side may be squeezed to death, and the door cannot be opened. To prevent this problem, a door stop is placed on the inside of the door of the boxcar. Now used car door baffles have two structural types, one is that the top is a pile-type slat structure, which often punctures the cargo packaging, affects the normal transshipment of the cargo, and causes unnecessary losses. Another structure is composed of a top horizontal board, a middle horizont...

Problems solved by technology

There are two structural types of the door baffles currently in use. One is the top of the pile-type slat structure. Its existence often punctures the cargo packaging, affecting the normal transshipment of the cargo and causing unnecessary losses.

Another structure is composed of a top horizontal board, a middle horizontal board and multiple
