Embodiment
Below in conjunction with the drawings and specific embodiments, the present invention done concrete detailed description further.
As shown in the figure, a kind of sterilization still seal-locking mechanism, comprises the seat ring 2 and pot cover that are located at still body 1 opening place.
Being provided with between seat ring 2 and pot cover and connect circle 4 and turning collar 3, match with the right side of seat ring 2 and be fixedly connected with (convenient in order to describe, the left and right of left and right described herein and accompanying drawing 3 itself is consistent) in the left side of described connection circle 4. Connecting the excircle of one end that circle 4 is connected with seat ring 2 and be provided with the step of annular, turning collar 3 is arranged in the ring groove that the side that this step formed opens.
On the end face of seat ring 2 towards turning collar 3, the location interval corresponding with turning collar 3 is provided with multiple groove, a slide 10 it is equipped with in each groove, (slide 10 is the bottom of slide 10 towards one end of bottom portion of groove for the bottom of slide 10, the other end is the top of slide 10) it is provided with the first compression spring 9, the ear plate being connected on slide 10 is from outside the radial slot being located at seat ring 2 corresponding end-faces reaches seat ring 2.
First compression spring 9 can prevent lock block 14 to be free to slide on pull bar 13, and can ensure to lock accordingly fully contacting of block 14 and pot cover, it is to increase locking effect.
Being hinged with a pull bar 13 by hinged axle 11 on ear plate, the medullary ray of hinged axle 11 and the central axis of seat ring 2 are arranged, and the other end at pull bar 13 is provided with the lock block 14 that can be locked at by pot cover and connect on circle 4.
Being interval with the same number of circumferentially deep-slotted chip breaker from the superficial to the deep with slide 10 on the end face of seat ring 2 at turning collar 3, multiple deep-slotted chip breaker direction from the superficial to the deep is consistent, and the top of slide 10 and corresponding deep-slotted chip breaker coordinate to be installed.
Lock block 14 can be in the cover tubular with hook head, lock block 14 is sleeved on the outside of pull bar 13, pull bar 13 is provided with the 2nd compression spring 12 in the part locked between block 14 and hinged axle 11 end, the other end at pull bar 13 has been threaded connection regulating handle 16, and the hook head on lock block 14 is for locking with pot cover.
When the present invention uses, rotating tension bar 13, lock block 14 is made to coordinate installation with pot cover, then rotary motion circle 3, deep-slotted chip breaker 301 from the superficial to the deep is utilized to make slide 10 slide in groove thus drive pull bar 13 close to still body 1 by hinged axle 11, finally making lock block 14 be locked at by pot cover connects on circle 4, and now the first compression spring 9 bottom slide 10 is in compressed state.
Lock block 14 is sleeved on the outside of pull bar 13 and coordinates the setting of the 2nd compression spring 12, can ensure when using regulating handle 16 degree of tightness of lock block 14 to be regulated, pot cover all can be played the effect of locking by each lock block, thus ensures validity and the persistence of sealing and locking further.
When needs releasing lock stops, the process that reverse rotation turning collar 3, first compression spring 9 resets drives pull bar 13 to move to the direction away from still body 1 by hinged axle 11, thus lock block 14 is discharged from pot cover.
Hinged axle 11 can adopt pin or bolt.
In order to ensure to seal the validity of locking and can be close to further, be provided with heavy hole section in one end of contacting with regulating handle 16 of lock block 14, be provided with in the section of heavy hole for regulating handle 16 is carried out locking and with the 3rd compression spring 15 locked.
In order to make structure compacter, being provided with blind hole in the bottom of slide 10, one end of the first compression spring 9 is arranged in blind hole, and the other end stretches out in its natural state outside blind hole, and this end can be fixedly connected with the bottom of groove.
Connect and it is fixedly connected with the heavy head screw 5 being located in heavy head bore by heavy head bore between circle 4 and seat ring 2. Thus ensure the sealing that mode of connection can not have influence on pot cover and be connected between circle 4.
Specifically, the structure of pot cover can comprise and be connected the retainer 7 that circle 4 fitted seal is installed and the end socket 8 being connected on another end face of retainer 7. Also can coordinate, connecting circle 4, the sealing groove that annular is set on the end face installed with retainer 7, in sealing groove, be provided with rubber seal 6. Thus ensure pot cover further and the sealing effect being connected between circle 4.
