Description
Technical field
The present invention relates to a kind of rocket projectile reliably to open the cabin mechanism, belong to rocket projectile technical field.
Background technology
When cabin, the front and back body of rocket projectile docks, the helicitic texture that conventional method adopts usually connects, this screw connection structure, for the relatively light rocket projectile of weight, both can meet bonding strength during rotary motion, can realize again being separated reliable separation between the two cabin bodies that need.But for the rocket projectile that cabin, front and back body weight is larger, learn through test, the axial shearing force that cabin, front and back body connecting portion is subject under accumulating and emission state is less, only can meet the demands by the shorter section of being threaded; And the circumferential shearing force of body High Rotation Speed generation is larger in transmit state, adopting the single screw connection structure of tradition just must increase bonding strength by the length extending the section of being threaded, disintegrating in advance when not reaching the predetermined area to avoid cabin, front and back body connecting portion; But the longer section of being threaded, opening the cabin to operate to body also been proposed higher requirement, is separated dose very few, cannot realizes effective separation; Separation dose is too much, can take more body space, and also can damage the miscellaneous part of body when being separated medicine effect, affects the normal work of rocket projectile.
Summary of the invention
The object of the invention is cabin body before and after the large weight in order to solve the traditional single helicitic texture connection of employing, there are the technological difficulties that cannot meet bonding strength simultaneously and effectively be separated, and a kind of " screw thread adds key " formula connection isolating construction is provided.
The object of the invention is to be achieved through the following technical solutions:
A kind of rocket projectile of the present invention reliably opens the cabin mechanism, comprises front connector, rear connector, screw, cushion block, key;
The rear end inwall of front connector inwardly has annular link slot, the leading portion of this annular link slot is processed with internal thread, the thread segment rear end of this annular link slot has the key connecting hole of a screwed hole and an axial aperture, this screwed hole is not communicated with the forward end of this key connecting hole, and the end, rear end of this key connecting hole is not communicated with the rear end end face of front connector;
The front end outer wall of rear connector is processed with the annular link slot matched with front connector rear end inwall, this annular link slot leading portion is processed with the external screw thread matched with front connector annular link slot leading portion internal thread, the thread segment rear end of this annular link slot has the key connecting hole of an axial aperture, this key connecting hole is consistent with the key connecting hole width on front connector, and the end face distance at two ends, key bottom is greater than the length of key connecting hole on front connector;
The width of key is consistent with the width of key connecting hole on front connector and rear connector, on the height of key and front connector and rear connector, the degree of depth sum of key connecting hole matches, the top, two ends of key all has the step trough matched with the key connecting hole degree of depth on front connector, and the bottom, two ends, front end of key is all processed as the inclined-plane of restraining to the inside;
The width of cushion block is consistent with the width of key connecting hole on front connector and rear connector, on the height of cushion block and rear connector, the degree of depth of key connecting hole matches, and on the length of cushion block and the end face distance sum at two ends, key bottom and rear connector, the length of key connecting hole matches;
The front end of rear connector insert before connector annular link slot in and be threaded, and the key connecting hole on front connector and the key connecting hole circumference on rear connector are aligned; By the key connecting hole of the lower front part of key through front connector, and connector key connecting hole front end after inserting, make the rear end of key put into the key connecting hole of rear connector, promote key backward, make the occlusion part screens of key connecting hole rear end on the cascaded surface of key rear end and front connector; Screwed hole on cushion block in the past connector is inserted, and is placed on the front end of the key bottom on rear connector in key connecting hole, make axial location in the key connecting hole of key on rear connector; Screw thread is connected in the screwed hole of front connector, and scribbles fastening glue between screw and this screwed hole.
Operation principle: in the duties processes such as transport at ordinary times, carrying, axial attachment force is born by the thread segment between front connector and rear connector; The circumferential shearing force that body High Rotation Speed produces in transmit state is born by bond structure; When carrying out lock out operation, separation medicine only need destroy the connecting thread between front connector and rear connector, can realize opening the cabin.
Beneficial effect:
Mechanism structure of opening the cabin of the present invention is simple, easy to assembly, the conventional thinking that length that conventional method can only extend connecting thread simply increases bonding strength has been evaded by the syndeton of " screw thread adds key ", before and after effective solution, connector is to bonding strength and the design contradiction be effectively separated, while the enough bonding strengths of guarantee, the reliable separation of front and back connector can be ensured again, there is important popularizing application prospect.
