Abstract
The utility model relates to the field of mechanical control and mechanical automation, particularly a linked structure for opening and closing a seal door. In the field of mechanical control and mechanical automation, the frequently used seal door fails to meet the operation requirement by using the mechanical structure only and requires the complicated electric control structure in the prior art, which leads to the complication in designing and manufacturing the whole mechanical control structure. The linked structure for opening and closing a seal door comprises a chamber, a bearing seat, a first linked rod, a second linked rod, a lifting handle, a top seat, a seal door and a locking mechanism. One section of the locking mechanism is rotationally connected with the fixed point on the second linked rod via a fixing hole and a bolt. An irregular parabola-shaped opening is cut off in the middle-point position of the locking mechanism. The included angle between the involute curve of the opening and the direction of the fixing hole is an acute angle. In the natural state, the edge where the opening is located in the locking mechanism is rested on a mid-section fixed pin of the linked structure.
Description
Technical field
The utility model relates to a kind of machinery control and automatic field, relates in particular to Kaifeng, a kind of interlock pass specifically and closes door.
Background technology
In the field of machinery control and automation, often use closing door mechanism, but closing door mechanism the most stubborn problem be exactly automatic switch mechanism, guarantee the simple and easy and excellent sealing performance of operation of closing door with this.Particularly after closing door is opened, sometimes also need to make closing door to keep opening-wide state a period of time, prior art is difficult to simple realization and uses the frame for movement demand of finishing the work merely, and will be by means of comparatively complicated electrical control, all more loaded down with trivial details concerning the design of whole machinery control and processing and manufacturing like this.
The utility model content
The utility model has provided Kaifeng, a kind of interlock pass and has closed door, in order to address the above problem.
The utility model comprises: cavity, supporting base, gangbar one, gangbar two, handle, footstock, closing door, locking mechanism, and described cavity is divided into seal section and open-mouth section, and open-mouth section is all identical with shape, the size of described closing door; Supporting base is fixed on the seal section of cavity, gangbar one rear end and supporting base front end are realized being rotationally connected by bolt, realize being rotationally connected by bolt with interlock one front end and described handle rear end in gangbar two rear ends, gangbar two front ends are connected by bolt with fixing hole on the footstock, and the top board and the closing door of footstock are fixed; Described closing door is realized being rotationally connected by hinge and cavity seal section and open-mouth section junction; The edge of closing door is embedded with rubber weather strip; Described locking mechanism, realize being rotationally connected by bolt by the fixed point on fixing hole and the gangbar two for one section, point midway at latch-up structure is the irregular parabola opening of pruning, described opening bursts at the seams and all acutangulates with the fixing hole direction, and limit, latch-up structure split shed place nature rides against on the dead bolt in link gear one stage casing.
Utility model is with respect to the distinguishing feature of prior art: when using the utility model, only need operating personnel's handle, closing door is rotated around its fixed point, when the opening on the locking mechanism runs on the dead bolt on the linkage structure one, fixedly fasten and snap in the opening, realize that whole interlock closes the locking of opening closing door mechanism; When needs are closed when sealing, only need locking mechanism is stirred in the other direction along opening, dead bolt is dropped out from opening, whole linked switch closing door mechanism will have self gravitation to return to closed condition; The whole operation process is easy, and locking back Stability Analysis of Structures is beneficial to and is useful for each mechanical field.
