Drop resisting and shock absorption double-layer suitcase

Abstract

The invention discloses a drop resisting and shock absorption double-layer suitcase which comprises a first case body, wherein a lifting handle is arranged at the top end of the first case body; a piece of covering cloth and a second case body are arranged in the first case body; the covering cloth is located between the first case body and the second case body; the periphery of the covering cloth is fixed on the inner wall of the first case body; two spring devices are arranged on each of two sides and the bottom end of the second case body; the spring devices comprise springs and spring seats; two ends of the springs are connected with the spring seats; one end of each spring device is fixed on the inner wall of the first case body, and the other end of each spring device is fixed on the side wall, away from the second case body, of the covering cloth; a buffering block is arranged between the two spring devices on the same side. The drop resisting and shock absorption double-layer suitcase is compact in structure, attractive in appearance, low in cost and convenient to use, can be widely used by chip manufacturing enterprises, office staff and scientific and technical workers, and can be used for protecting fragile objects such as silicon wafers or organic glass and further protecting precision instruments and the like.

Description

technical field [0001] The invention relates to the technical field of suitcases, in particular to a drop-proof and shock-absorbing double-layer suitcase. Background technique [0002] In people's daily life, suitcases are often used to carry and hold valuables such as salutes. Therefore, suitcases are an important life or office supplies, especially in engineering sites, technicians often use suitcases to carry and carry Store fragile items such as semiconductor chip wafers and plexiglass. When the suitcase containing the fragile items accidentally falls on the ground, it is easy to break the contained items because there are no protective measures. Before the present invention, people Most of the suitcases used do not have anti-fall safety protection functions, such as ordinary cloth suitcases, portable suitcases, etc., which are just a simple layer of leather cloth, without the effect of vibration reduction and anti-vibration. Some so-called anti-drop suitcases, the anti...

[0002] In people's daily life, suitcases are often used to carry and hold valuables such as salutes. Therefore, suitcases are an important life or office supplies, especially in engineering sites, technicians often use suitcases to carry and carry Store fragile items such as semiconductor chip wafers and plexiglass. When the suitcase containing the fragile items accidentally falls on the ground, it is easy to break the contained items because there are no protective measures. Before the present invention, people Most of the suitcases used do not have anti-fall safety protection functions, such as ordinary cloth suitcases, portable suitcases, etc., which are just a simple layer of leather cloth, without the effect of vibration reduction and anti-vibration. Some so-called anti-drop suitcases, the anti-drop devices of these suitcases are simply provided with some sponges, leather pads or soft plastics in the bag, which have poor vibration damping effect, and the protection method is relatively simple, which cannot effectively protect the wafer. Fragile items such as silicon wafers are not easy for people to use safely, and some suitcases with shock-absorbing devices are relatively fragile on the outside, or are directly made of flexible materials, which are easy to deform or break. For this reason, we propose a Anti-drop and shock-absorbing double-layer suitcase to solve the above problems
