Abstract
A kind of screwing type transfer chamber cabin door device, object is for existing technical disadvantages, and design one in use can be easy to open and closedown, can meet again the glove box transfer chamber door gear that it vacuumizes the requirement of sealing.The utility model comprises transfer chamber housing and the hatchcover of tubular, hatchcover is threaded connection and is arranged on transfer chamber housing upper face, with left ear and auris dextra on hatchcover excircle, left ear, auris dextra and hatchcover are monolithic construction, hatchcover is built with the sealing ring of ring-type, with anti-slip veins outside hatchcover, jug is also with in outer end to hatchcover.The utility model structure is simple, economical and practical.
Description
Technical field
The utility model relates to a kind of laboratory glove case, is specifically related to a kind of convenient closedown and opens and the transfer chamber door gear of the good glove box of sealing property.
Background technology
Glove box is filled with in casing by high purity inert gas, and be circulated throughout the laboratory equipment of the active material filtered wherein, also claims vacuum glove box, inert gas shielding case etc.
Glove box comprises main body case and transfer chamber, and transfer chamber is located at main body case side.Transition hatch door that glove box configures needs to have the advantages that to be easy to open with closing, and requires its good seal performance, and the transition hatchcover complex structure of existing transition hatch door preparation and more difficultly to open and closedown, sealing property is poor.
Circular seal ring ratio between existing glove box transition hatch door and lid is easier to wear and tear, so make its sealing property be deteriorated, circular seal ring is easily loosening is also a reason of poor sealing performance.Handle on transfer chamber hatchcover and transition hatchcover are two parts instead of an entirety, and when its handle loosens, transition hatchcover is also easier to gas leakage.It is desirable that goodish sealing property between existing transition hatch door and transfer chamber hatchcover, this just requires that lid and hatch door are that positive round can not have slight offset, otherwise also can cause gas leakage, and sealing property is deteriorated.Need the operation of band multi-layer gloves not very convenient glove box built-in function person, the gap between hatchcover and door is very little, adds the sealing ring on hatchcover, and sealing ring makes its change that rubs large, makes operator be difficult to be closed by hatchcover and open.
Summary of the invention
The purpose of this utility model is for existing technical disadvantages, and design one in use can be easy to open and closedown, can meet again the glove box transfer chamber door gear that it vacuumizes the requirement of sealing.The technical solution of the utility model is as follows.
A kind of screwing type transfer chamber cabin door device, it is characterized in that: the transfer chamber housing and the hatchcover that comprise tubular, hatchcover is threaded connection and is arranged on transfer chamber housing upper face, with left ear and auris dextra on hatchcover excircle, left ear, auris dextra and hatchcover are monolithic construction, hatchcover is built with the sealing ring of ring-type, and with anti-slip veins outside hatchcover, jug is also with in outer end to hatchcover.
According to described a kind of screwing type transfer chamber cabin door device, described left ear, auris dextra are be connected to the circulus on hatchcover excircle.
The utility model structure is simple, economical and practical.

Detailed description of the invention
Glove box comprises glove box body 7 and transfer chamber, and transfer chamber housing 1 is located at main body case side.Screwing type transfer chamber comprises transfer chamber housing 1 and the hermetically-sealed construction of tubular, and this structure is made up of hatchcover 3, sealing ring 9, left ear 2, auris dextra 5.Be screw connection structure between transfer chamber housing 1 and hatchcover 3, making transfer chamber hatch door also than being easier to, requires lower to transfer chamber hatch door and hatchcover 3 circularity with hatchcover 3.Simple helicitic texture plays the effect screwing and fix, and operator also can be allowed to open very easily and close transfer chamber.The sealing ring 9 of hatchcover 3 inside is embedded in lid, can not affect the difficulty of lid hatchcover, mainly play sealing function.The left ear 2 of hatchcover 3 is an entirety with auris dextra 5 and hatchcover 3, and namely not worrying loosening can affect sealing property but also play thrust when screwing tight, and contributes to closing and opening transfer chamber.
Left ear 2 is circulus with auris dextra 5, is welded on hatchcover 3 both sides.Leader 4 is welded on the surface of hatchcover 3, and handled easily person is hand-held.When installing hatchcover 3, one holds handle 4, the hand-held left ear 2 of another hand, is convenient to aim at screw thread, improves installation effectiveness.Handle 4 and hatchcover 3 are an entirety, close and hand can be prevented when opening hatchcover 3 sliding as operator.Hatchcover 3 is the same with glove box material, is metal material, because hatchcover 3 is not very large (hatchcover diameter about 10cm), and therefore can not be too heavy.
The utility model is made up of left ear 1, hatchcover 3, auris dextra 3, transfer chamber housing 1, sealing ring 9, this screwing type transition hatchcover is characterised in that the right and left leaves left and right ear, facilitate it to screw and open, spiral lamination between hatchcover 3 and housing works the effect of screwing, its sealing is good to have sealing ring 9 to guarantee in lid, in order to avoid gas circulation inside and outside it.
Claims (2)
