Specific embodiment
The present invention will be further described with reference to the accompanying drawings and examples.
Referring to attached drawing 1-6, this sealing structure disclosed in this invention is primarily adapted for use in the outer cylinder of roller washing machine and outer
Sealing between cylinder front cover.This sealing structure is based on outer cylinder and outer barrel front cover is two independent separate structures.
This external cylinder of drum-type washing machine sealing structure, outer cylinder 1 including roller washing machine and disposed in parallel outer with outer cylinder
Cylinder front cover 4, further includes clump weight 7 and hasp.
Clump weight is the rectangular blocks for being above inner concave arc surface, and inner concave arc surface matches with outer drum outer wall, and clump weight is logical
The connectors such as bolt are crossed to be mounted below outer cylinder excircle.The front surface and outer cylinder leading edge of clump weight are in same level.Match
The front end face of pouring weight is connected with the guiding gutter of a strip structure, which is obliquely installed, and a water storage is arranged in low side position
Vessel.This guiding gutter 8 is additional prevention component, is mainly used to catch between outer cylinder front cover and outer cylinder front end face
Water avoids leak.
Corresponding limit base 6 is respectively arranged on the excircle of outer cylinder front end face and outer cylinder front cover.Limit base is hollow
Cylindrical structure, spacer pin 5 is inserted into limit base.On outer cylinder front end face, its circumferencial direction is provided with a seal groove.Outside
On the medial surface of cylinder front cover, its circumference is provided with a sealing strip.Sealing strip 3 presses in seal groove 2.Preferably, sealing
The structure of slot and sealing strip can be divided into following several: it is spherical groove body that seal groove, which is the section of outer openings, sealing strip be with
Its section to match is spheric annulus body；Or seal groove is the groove body of trapezoid cross section, the sealing strip is and its phase
The cyclic annular body for the trapezoid cross section matched；Or seal groove be section be outer narrow inner width polygon groove body, the sealing strip be with
Its section to match is the polygonal ring shape body of outer narrow inner width.Sealing strip presses in seal groove, realizes sealing.
As preferred plan: as shown in Fig. 6, seal groove is the curved-surface structure for the concave and downward convex that section is S-shaped shape, described
Sealing strip is the convex recessed curved-surface structure of corresponding reverse-s shape shape.Concaveconvex structure between seal groove and sealing strip
Two sealed structures are formed, the sealing performance of sealing strip and seal groove is improved.
Outer cylinder mainly passes through the hasp on their excircles with outer barrel front cover and is fixedly connected.Hasp includes briquetting 12 and drag hook
10, briquetting and drag hook are linked together by connection component, and briquetting is arranged on the end face of inner cylinder front cover, and drag hook movable set exists
The end of spacer pin, the position by changing drag hook are realized drag hook to the tension of spacer pin and are loosened.
According to the display of actual installation condition, hasp is divided into sliding structure and push type structure, space biggishly
Side uses sliding hasp, selects push type hasp in the lesser place in space.
The hasp of sliding structure, briquetting 12 are rectangular blocks, and drag hook is elliptical annular structure.Briquetting upper surface passes through
Fixing bolt 9 is equipped with a upper cover, and upper cover is coated on briquetting upper surface, and fixed ring 11 is fixedly mounted on the tail end of upper cover, drag hook
10 movable sets are in fixed ring.Drag hook does 0-180 ° of rotation in fixed ring.The contact point A of drag hook bottom end and briquetting to pressure
The distance of block bottom surface is less than contact point A to the distance of bottom end on rear side of briquetting.By the swing of drag hook, drag hook bottom squeeze briquetting,
To realize tension and loosen.
The hasp of push type structure, briquetting 12 are rectangular panel body, and the top of drag hook is ring junction corresponding with spacer pin
Structure, the lower part of drag hook are around on pull rod 15, and free end is extruded in 14 inside of backing pin, and backing pin is fixed on briquetting 12.In briquetting
Centre is provided with the fixing bolt with outer barrel side wall fixed-link.The lower part of drag hook is wound on pull rod respectively, the top of drag hook and
Lower part constitutes the pressure spring structure compressed to the briquetting back side.
The tail portion of the hasp of sliding structure, drag hook and spacer pin connects, be by drag hook by the tail portion of spacer pin to
Briquetting direction tenses, the point using spacer pin as tensioning function, and briquetting is close to the side of outer cylinder front cover, and the side of outer cylinder front cover is to make
With face, outer cylinder and outer cylinder front cover are closely joined together.
The stem of the hasp of push type structure, drag hook and spacer pin connects, in order to improve pressing force, with the push type
The stem of the spacer pin used joined together by the hasp of structure is provided with the position-arresting disk for being greater than spacer pin outer diameter, with limit
The stepped structure setting of head end is sold, drag hook covers in spacer pin head end periphery, presses against on the upper surface of position-arresting disk, play limit
Effect.The stem of spacer pin is suppressed downwards by drag hook, briquetting is fixed on the side of outer cylinder front cover by fixing bolt, limit
Position pin is linked together outer cylinder and outer cylinder front cover by limit base, using the side of outer cylinder front cover as acting surface, the head of spacer pin
Portion is position, the both ends of similar pressure spring, down force, and drag hook being compressed in limit base tightly by spacer pin is realized outer
The close connection of cylinder and outer cylinder front cover.
