Lower overturning door device of skirt edge box

Abstract

The invention relates to a skirt edge box door structure of a special vehicle, in particular to a lower overturning door device of a skirt edge box. The lower overturning door device comprises tension spring hinges and a lower overturning door body, wherein one ends of the tension spring hinges are fixed to the bottom of the skirt edge box and located at an object storing opening of the skirt edge box; and the lower overturning door is fixed to the other ends of the tension spring hinges and used for closing the object storing opening of the skirt edge box. The lower overturning door device of the skirt edge box is small in occupied space, good in safety, free of auxiliary supporting and convenient to use, and the locking pressure of the lower overturning door can be adjusted.

Description

technical field [0001] The invention relates to a special vehicle skirt box door structure, in particular to a skirt box lower flap door device. Background technique [0002] With the continuous development of my country's economy and the continuous acceleration of the industrialization process, the risk of accidents increases accordingly, which promotes the development of emergency medical rescue equipment, so the demand for special vehicles for field medical rescue is constantly increasing. In order to increase the storage space, the two sides of the chassis of the vehicle adopt a skirt box structure. [0003] Such as Figure 13 As shown, the existing skirt box door adopts the lower flap structure for conveniently taking out the article in the skirt box, and nitrogen spring is housed on the chassis, and the nitrogen spring compresses the lower flap on the skirt box. Since the nitrogen spring cannot be used as a positioning support, an iron chain is installed between the s...

AI Technical Summary

Problems solved by technology

[0004] Since the nitrogen spring occupies a large space and the position of the skirt box is relatively low, the nitrogen spring is relatively close to the ground, and there is a safety hazard when driving on rough roads

[0005] The iron chain is easy to get stuck between the lower flap and the skirt box during the closing process of the lower flap. It is necessary to re-open the lower flap at a certain angle and wait for the iron chain to enter the skirt box before closing it, which makes it very inconvenient to close the lower flap , and the iron chain will continue to shake in the skirt box during driving, constantly colliding with the skirt box and the lower flap door to generate wear and noise, and even hit the items inside the skirt box, causing damage to the items
