Abstract
The invention provides a sealing locking device of a container door and relates to a mechanical device. The sealing locking device consists of handles, rotary arm locking shafts, a press block, a rotary arm support, rotary arms and a rotary arm shaft pin. The press block is fixedly installed on the container door. Two ends of the rotary arm locking shaft are respectively installed in reserved holes on two rotary arms, the handles are fixedly installed at the end positions of the rotary arm locking shafts on the outer sides of the rotary arms, the handles rotate to drive the rotary arm locking shafts to do axial rotation, the rotary arms are pulled from the opening to the closing of the container door, and a straight line distance from the axes of the rotary arm locking shafts to the top end of the press block is shortest. The handles rotate when the container door is shifted from a locking state to a closing state, and the press block is stressed to drive the container door to be tightly pressed gradually. The sealing locking device drives the rotary arm locking shafts with cross sections in shapes of eccentric circles to rotate through the handles, enables the cambered surface distance from the axes of the rotary arm locking shafts to the top end of the press block to change, and achieves change of a locking state and an unlocking state. The locking and sealing of the container door can be finished only by rotating the handles, operation is simple, and the sealing effect is good.
Description
Technical field
The present invention relates to a kind of mechanical device, be specifically related to a kind of sealing-locking device of container door.
Background technology
In leakproof tank or the closed environment, the airtight of door is the very important link of whole container, because container door needs to open, the change of closed condition, every realization is once opened after the state conversion of closing, need the squeeze receptacle door, make it fully to contact with the sealing band with door is complementary of container, thereby realize sealing.In the prior art, mostly be greatly flange, O-ring seal is joined the jam nut form, this kind locking needs repeatedly demolition jam nut, and the sealing of finishing container door needs the long period, the latching device of container door of the prior art because of its structures shape complex operation, heavy dumb.
Summary of the invention
Be to solve container door sealing arrangement complex operation, heavy inflexible problem in the prior art, the invention provides and a kind ofly seal that locking is effective, structure is installed container door sealing-locking device simple, simple operation.
A kind of sealing-locking device of container door, formed by handle, pivoted arm lock shaft, briquetting, rotating arm supporting base, pivoted arm, pivoted arm pivot pin, the container door installation end is installed bearing pin by one group and is fixedly mounted on the erection support of container body opening part, the process that container door is rotated around bearing pin just can realize its closing, opening with respect to container body, it is characterized in that: described briquetting is fixedly mounted on the container door, and its top is arcwall face; Two rotating arm supporting bases are fixedly mounted on the erection support of container body opening part, and the relevant position on rotating arm supporting base and the pivoted arm has mounting hole, and the pivoted arm pivot pin links together both by the mounting hole of rotating arm supporting base and pivoted arm; The two ends of pivoted arm lock shaft are installed in respectively two preformed holes on the pivoted arm, the end of the pivoted arm lock shaft in the pivoted arm outside is equipped with handle, the handle suit also is fixed on the pivoted arm lock shaft, rotate drive pivoted arm lock shaft by handle and axially rotate, the cross-sectional plane of pivoted arm lock shaft and briquetting corresponding position is eccentric or ellipse; When container door was closed from being opened to, the pulling pivoted arm made pivoted arm lock shaft outside cambered surface contact with the arc surface on briquetting top until fully tangent, and this moment, pivoted arm lock shaft distance of shaft centers briquetting top straight-line distance was the shortest; Container door is when being closed to locking state, turning handle, make pivoted arm lock shaft outside cambered surface continue rotation along the arc surface on briquetting top, the pivoted arm lock shaft is elongated gradually apart from the straight-line distance on briquetting top, then the moving container door of briquetting forced belt compresses gradually, when the pivoted arm lock shaft is the longest apart from the straight-line distance on briquetting top, container door locking.
The present invention drives by handle that to have cross-sectional plane be that the pivoted arm lock shaft of eccentric rotates, and makes the variation of cambered surface distance on the distance of shaft centers tripping piece top of pivoted arm lock shaft, makes briquetting drive container door and realizes locking and the not variation of locking state.Only need turning handle can finish to the container door lock sealing simple to operate, good sealing effect among the present invention.
