Abstract

The utility model relates to the structure of a sealing door or a cover. Devices and instruments often need the sealing door or the cover, and the solution of the prior art is that a hand wheel screw press plate frame or a spring latch is arranged on the door or the cover. The utility model provides with the structure of the sealing door or the cover of a press handle at both sides of the door or the cover, and a movable type hinge which is installed on one side of the door or the cover in radial direction. The door or the cover with the structure has the advantages of good sealing effect and convenient operation.

Description

Sealing door or cover

The utility model relates to special installation relevant with door and window or measure class.

On some instruments in fields such as chemical industry, health, kitchen fittings or equipment, need hermatic door or lid.The mode that solves door or lid sealing problem in the prior art has two kinds.A kind of is as shown in fig. 1 handwheel spiral presser type structure, and this sealing compressing structure is to rotate on screw rod by handwheel to slide, and extruding is fixed on pressing plate on the door-plate and finishes the sealing task.Because handwheel and pressing plate are plane contact, under the caulking gum reaction force, the frictional resistance that produces is very big, need screw and unscrew handwheel during the opening and closing sealing, waste time and energy, need the door or the lid of sealing, just can finish with many groups of such structures, moreover chemical industry, disinfecting, kitchen fittings use under moist or greasy ambient conditions mostly, and this has just increased difficulty and trouble degree when opening and closing greatly.Handwheel need raw material are many in addition, volume is big, and the cost height is made complicated difficulty.When assembling this kind structure because door or lid be affixed on the seal by cover and axle and a screw mandrel, poor stability, or lid and doorframe or casing mutual position error big, rotate low and deep dumbly, bring very big difficulty to erection work.This kind structure heaviness, the volume that takes up space is big.Another structure is a spring latch as shown in Figure 2, and this lock hermetically-sealed construction is to be used with one group of overhead hinge, reaches sealing purpose.It is to promote roller dead bolt on the handle by spring, finishes and closes or lock task by being fixed on the sliding ditch in inclined-plane on doorframe or the casing.The advantage of this structure is that switch is convenient.Shortcoming is can't seal near overhead hinge one end, and because of after this end loads onto hinge, door is fixed with the distance of framework, can't compress sealing, so its sealing effectiveness is undesirable.

The purpose of this utility model is to provide a kind of good sealing effect, hermatic door easy to use or lid structure.

The purpose of this utility model is achieved in that it comprises door or lid, is equipped with linkage in a side, is equipped with hold down gag in both sides.The door or the linkage of lid and doorframe or casing are packaged type hinge radially, the both sides that hold down gag employing sealing load handle, hold down gag are installed on.Its radially the packaged type hinge form by main shaft, auxilliary axle, junction plate and two fixed heads.Main shaft is connected on the fixed head, is fixed on doorframe or the casing.Auxilliary axle is connected on another fixed head, is fixed in door or covers, and is connected by junction plate between the major-minor axle, can rotate between major-minor axle and the junction plate.With fixed head that auxilliary axle links to each other on have a slotted hole, the not fixed end of main shaft extend among the slotted hole.The sealing load handle comprises that pressure handle, base, draw ring, adjusting give tight bolt and give tight base.One end of pressure handle is connected on the base with one, and base is fixed in door or covers, and regulates to give tight bolt and be threaded with giving between the tight base, gives tight base and is fixed on doorframe or the casing.Draw ring passes an end that gives tight bolt, and can rotate.All be equipped with pressure handle in the both sides of door or lid (hinge side and opposite side thereof are installed).

Compared with the prior art advantage of the present utility model is:

1, good sealing effect.Give tight bolt by adjustment, can obtain desirable sealing load, both sides all are equipped with the pressure handle of right quantity, and adopt radially packaged type hinge, can guarantee to closely cooperate between door or lid and doorframe or the casing, reach sealing effectiveness.Even when O-ring seal is aging, also can obtain more satisfactory sealing effectiveness.

2, easy to use.As long as open the pressure handle of a side during unlatching, get final product, as long as draw ring is suspended on the pressure handle, compresses pressure handle downwards and get final product during sealing.And pressure handle promptly is to compress seal, is again to open handle, is convenient to switch.

3, compare with handwheel spiral presser type structure, can save raw material and occupy the space.

4, application is wide.Can be widely used in different field such as chemical industry, disinfecting, kitchen fittings, need on the instrument or equipment of hermatic door or seal cover.As steam, steamer, disinfection cabinet, large-size horizontal, tumbling-box washing machine, refrigerator or the like.
