Detailed description of the invention
Concrete structure of the present invention is see shown in Fig. 1-13.Shown in Figure 1, preventer forms primarily of housing 1, side door 2, clip 3, push rod 4 and side door seal assembly 5.
Shown in Figure 4, there is vertical rectangle groove 101 and 103 at housing 1 two ends, rectangular boss 102 and 104, and there is vertical rectangle groove 201 and 203 in side door 2 and body contact face, rectangular boss 202 and 204.After housing 1 and side door 2 sealing surface note close, groove 101 and groove 201 form a trapezoid space, can hold clip 3.
Shown in Figure 5, can be vertical on the right side of housing groove 101,103 or inclination.It can be vertical on the left of side door groove 201,203 or inclination.After housing 1 and side door 2 sealing surface note close, groove 101 and groove 201 form a trapezoid space, can accommodate the clip 3 of groove 301 structure.
Shown in Figure 4, clip 3 is U-shaped structure, and there is perpendicular grooves 301 centre, and the width of groove 301 equals boss 102 and boss 202 width sum.There is boss 302 and 303 clip 3 both sides.The width of boss 302 and 303 is slightly less than housing groove 101 and side door groove 201.
Shown in Figure 5, clip 3 also can be multiple tooth groove, and corresponding side door 2 and 1 housing is also multiple tooth groove.Shown in Figure 11, there is T-shaped groove 308 Integral keeper 3 both sides, can coordinate with 405 round platforms installed on push rod bolt 4, by rotating both sides bolt 4, round platform 405 can move up and down, and drives Integral keeper 3 to move up and down, completes Integral keeper 3 and be connected with housing 1, the quick of side door 2.The fitting face 307 of the multiple tooth groove of clip 3 and housing side door can be straight, also can be the inclined-plane of self-locking.
Shown in Fig. 8,9,10,12,13, clip 3 can be overall, also can be segmented Split type structure.The clip 3 of certain length is divided into 2 or 3 sections, and every section of clip has a locating hole to be fixedly connected with by screw thread with side door with housing by clip.The locating hole of clip 3 can be vertical (Fig. 8,12), also can be level (Fig. 9,13).
Split type clip can adopt alignment pin to be connected with housing side door.
Integral keeper can adopt the bolt push rod of both sides to be connected with housing side door.
Side door sealing can adopt axial seal structure (Fig. 6).Sealing framework 5 is ellipsoidal structure, and side door seals 5 outer seal surface each side the groove 501 and 502 can installing O-ring seals.After installation, groove 501 ovaloid seal groove corresponding to housing is formed and seals, and groove 502 ovaloid seal groove corresponding to side door is formed and seal.Groove 501 and 502 spacing is comparatively large, and when there is gap when between housing 1 and side door 2, groove 501,502 still can be positioned at corresponding housing, side door sealing groove face.
Side door sealing also can adopt end face seal structure (Fig. 7).Sealing framework 6 is ellipsoidal structure, the oval-shaped groove 602 can installing O-ring seals is had in the outside of skeleton 6, have with a side end face of housing seal the oval-shaped groove 601 can installing O-ring seals at skeleton 6, the side that groove 601 is relative fluted 603, can install rubber spring.
Side door sealing framework shape is determined according to housing flashboard cavity shape, and can be ellipsoidal structure, also can be rectangular configuration.
Operating principle: when needs connect housing and side door assembly, by hydraulic control or Non-follow control, side door and housing are adjacent to, boss 102 on housing is fitted with side door boss 202, groove 101 on housing forms a U-shaped space with the groove 201 on side door, clip 3 is put into the U-shaped space that housing groove 101 is formed with side door groove 201, again alignment pin 4 is passed vertically through clip, screwed in place pin 4, clip 3 is fixed on housing 1 and side door 2.When there being well to press in preventer, side door 3 is stressed to move right, and side door boss 202 right flank and clip 3 groove 301 right contact, fix with housing boss 102 left contact on the left of clip 3 groove 301, clip 3 secures the position of housing and side door, completes housing and is connected with the quick of side door.(Fig. 2,3,4).When there being well to press in preventer, side door sealing 5 is radial seal, and sealing is not subject to the impact in housing and side door gap.Skeleton 66 under the effect of pressure face product moment, is pressed on end face that housing contact with side door, seals the impact not being subject to housing and side door gap by side door sealing.
When needs be separated side door assembly time, take out alignment pin 4, from above and below take out clip 3, by hydraulic control or Non-follow control, side door assembly is separated with housing, completes the Quick release (Fig. 1,2,3) of housing and side door.
Also can adopt and rotate both sides push rod bolts and drive Integral keeper to move up and down, complete engaging of clip and housing side door.After clip and housing side door are thrown off, the T-shaped groove 308 on clip can move backward along round platform 405, clip 3 is positioned on rear side of side door 2 sealing surface completely, is convenient to vertically hang get flashboard.
