Vacuum cinerary casket

Abstract

The vacuum type cinerary casket comprises a shell with a bottom and an air exhaust nozzle with a one-way valve, the shell and the air exhaust nozzle are integrally formed in a stamping mode, two outwards-sunken device tables are arranged at the symmetrical positions of the side wall of the shell, and an annular folded plate is fixedly arranged on the inner wall of the upper end of the shell; a soft airtight ring is arranged at the bottom of the annular folded plate between the annular folded plate and the shell in a contact mode, an air pressure cover is arranged on the inner wall of the upper end of the shell, and downward bent rings are fixedly arranged on the edges of the inner wall and the outer wall of the air pressure cover and connected between the annular folded plate and the shell through threads in a threaded mode. Threads used for keeping internal and external balance when the bending ring moves downwards are arranged on the contact faces of the annular folding plate, the shell and the bending ring. According to the vacuum cinerary casket, the problems that an upper end sealing device is directly pressed on a sealing ring under the maximum pressure before an existing vacuum cinerary casket is vacuumized, so that the sealing ring is overloaded, the sealing effect is poor, even the sealing ring is directly broken, and sealing fails are solved.

Description

technical field [0001] The invention relates to the technical field of urns, in particular to a vacuum urn. Background technique [0002] Birth, old age, sickness and death are natural laws, and there should be no exceptions in ancient and modern times. With the development of the economy and the progress of the society, the forms of human funerals are also advancing with the times, and in the world it is basically burial and cremation. In China, the state advocates the implementation of cremation, and the state advocates the way of ashes storage and other methods that do not occupy or occupy less land. At present, the used urns of the mode of ashes deposit, the form is various. However, the ubiquitous problem is that the urn is only used as a storage device for the ashes. Although the appearance is elegant, it is not sealed, and there is a problem of missing ashes; especially for the spread of pathogenic substances that may threaten human health in the ashes Without effe...

Problems solved by technology

[0005] The purpose of the present invention is to provide a vacuum type urn to solve the existing vacuum form of the urn proposed in the above-mentioned background technology. The sealing ring is overloaded, the sealing effect is poor, and it even directly causes the sealing ring to break, causing the problem of sealing failure to occur; secondly, the inside of the urn is usually locked by a bayonet device, and there will always be some problems in the production and processing of mechanical parts. The error gap, as the external atmospheric pressure continues to exert pressure for a long time, it will eventually lead to metal fatigue in the mechanical parts, resulting in loosening and air leakage, which will lead to sealing failure. Secondly, most of the existing urns use square corners. Design, the rubber strip is squeezed by the sharp corner for a long time in the square groove, it may break when vacuuming, or the rubber strip is squeezed by the corner for a long time, resulting in stress concentration, which may lead to dogma The problem of fracture occurs, so that the urn has the problem of air leakage and loosening
