Embodiment Construction
[0024] Below in conjunction with accompanying drawing and specific embodiment the present invention is described in further detail:
[0025] The invention provides a self-tightening sealing structure for the connection between the initial storage room and the base, which solves the problem of long installation time caused by the connection between the base and the initial storage room to ensure good sealing performance. By changing the base and the initial storage room The sealing form improves the sealing performance of the connection parts, thereby reducing the total number of fasteners installed, shortening the total time-consuming installation of fasteners, and improving installation efficiency under the premise of ensuring good gas sealing.
[0026] Such as figure 1 Shown is a schematic diagram of the self-tightening seal structure. It can be seen from the figure that a self-tightening seal structure for the connection between the primary storage chamber and the base incl...

The invention discloses a self-tightening sealing structure for connecting an initial chamber and a base, and relates to the field of self-tightening sealing structure deigns. The self-tightening sealing structure for connecting the initial chamber and the base comprises an initial chamber rear flange section, a connecting section, a base flange and bolt components, wherein the cross section of the connecting section is of a U-shaped structure; the opening of the connecting section is placed horizontally; the side wall of the top end of the connecting section is fixedly connected with the initial chamber rear flange section; the cross section of the connecting position between the initial chamber rear flange section and the connecting section is of an L-shaped structure; the initial chamber rear flange section and the connecting section fixedly connected through the bolt component at the connecting position; the side wall of the bottom end of the connecting section is fixedly connectedwith the base flange; the cross section at the connecting position of the base flange and the connecting section is a top of an ear-shaped structure; the base flange and the connecting section are fixedly connected through the bolt component at the connecting position; and according to the self-tightening sealing structure for connecting the initial chamber and the base, on the premise of ensuring good gas sealing performance, the total number of mounting fasteners is reduced, the total time consumption for mounting the fasteners is shortened, and the mounting efficiency is improved.
Description
technical field [0001] The invention relates to the design field of a self-tightening sealing structure, in particular to a self-tightening sealing structure used for connecting an initial storage chamber and a base. Background technique [0002] The base is directly connected to the initial storage room, and the base is connected to the bottom of the initial storage room, which mainly realizes two functions: [0003] (1) To withstand internal pressure and realize gas sealing during ejection; [0004] (2) Transfer the ejection recoil load to the launch pad. [0005] In order to ensure good sealing of the gas and effective transmission of loads, the current connection between the base and the initial storage chamber relies entirely on a large number of bolts and fasteners to ensure good sealing, which causes the problem of long installation time. Contents of the invention [0006] The purpose of the present invention is to overcome the above-mentioned deficiencies in the ...
