Embodiment Construction

[0014] The preferred embodiments of the present invention will be described in detail below in conjunction with the accompanying drawings, so that the advantages and features of the present invention can be more easily understood by those skilled in the art, so as to define the protection scope of the present invention more clearly.

[0015] refer to Figure 1-2 As shown, the square frame type large positive and negative pressure difference fragile protective cover structure of the present invention includes an end frame 1, and one side of the end frame 1 is provided with a cover body 2, and the cover body 2 is an elliptical surface protruding outward, and the elliptical surface The convex surface and the concave surface are respectively used to withstand positive pressure and negative pressure, and the positive pressure is three times greater than the negative pressure. Among them, the concave surface center of the cover body 2 is symmetrically provided with a plurality of gra...

Abstract

The invention discloses a box-type fragile protective cover structure with a large positive-negative pressure difference. The box-type fragile protective cover structure with the large positive-negative pressure difference comprises an end frame; a cover body is arranged on one side of the end frame and is an elliptical face protruding outwards; a convex face and a concave face of the elliptical face are used for bearing positive pressure and negative pressure correspondingly; and the positive pressure is larger than three times the negative pressure. A plurality of reinforcement layers thickening gradually are symmetrically arranged between the center of the concave face of the cover body and the bottom side close to the end frame. First weakening grooves, second weakening grooves and third weakening grooves are formed in the diagonals of the internal concave face of the cover body, the four lateral sides of the end frame and the peripheral corners of the end frame correspondingly, and are different in depth. The box-type fragile protective cover structure with the large positive-negative pressure difference solves the design problem of a fragile protective cover structure with the positive pressure being larger than three times the negative pressure.

Description

technical field [0001] The invention relates to the technical field of fragile protective covers, in particular to a square frame-shaped fragile protective cover structure with large positive and negative pressure differences. Background technique [0002] The traditional system with a fragile protective cover adopts a mechanical method to open the fragile protective cover, and a blasting method to open the fragile protective cover. The design of this fragile protective cover only needs to meet the negative pressure index. The design is simple, but the operation of the entire system Complex and poor reliability. In order to make the system respond quickly and operate easily, the modern fragile protective cover uses a certain pressure and high-speed gas to open the fragile cover, but this pressure has a certain limit, that is, the fragile protective cover is required to be broken under the limited positive pressure, but in The fragile protective cover is intact when the nega...
