It is an annulus among part, annulus edge is equipped with external screw thread, and annulus both ends connect the cambered surface lower edge of upper cover by two crossbeams；Institute
It states and is equipped with box body connecting component at box body upper opening；It is an annulus among the box body connecting component, and the circle ring inner wall
Equipped with internal screw thread, the annulus of box body connecting component connects box opening two sides by two crossbeams；In the box body connecting component
Between the internal diameter of annulus be equal to the outer diameter of the annulus among upper cover connecting component, and on the annulus among the box body connecting component
Internal screw thread line type and upper cover connecting component among annulus on external screw thread line type match；The box body lower center position
Equipped with bottom protrusion；The bottom protrusion center is equipped with for the aperture across connecting shaft；It is one below the bottom protrusion
The slot of invagination, slot is interior to be equipped with internal screw thread；The connecting shaft connecting component is a cylindrical structure, and connecting shaft connecting component is straight
Diameter be equal to the bottom protrusion below slot internal diameter, and connecting shaft interconnecting piece outer wall be equipped with in the slot below bottom protrusion
The external screw thread that screw thread line type matches；Connecting shaft interconnecting piece center is equipped with for the lower opening across connecting shaft；The connection
Axis connection portion central aperture inner wall is equipped with recessed groove, fills sealing lubricating oil in the recessed groove.
Application method: box body connecting component being screwed with upper cover connecting component by screw thread and is connect, and connecting shaft is inserted into and is connected
Then connecting shaft connecting component is screwed in bottom protrusion, thereby realizes the connection of box body and upper cover by spindle connecting component,
And connecting shaft protrudes into tray interior.Disassembly process is opposite with the above process.
Advantages and beneficial effects of the utility model lie in that a kind of limit switch of the utility model, realizes limit and opens
Close the easy installation and removal of box.Upper cover and box body part are not needed using screw connection, and the sealing strip of upper cover lower edges
It can guarantee to form sealing between box body and upper cover again.The installation of connecting shaft is convenient in the design of bottom protrusion and connecting shaft connecting component
And on the one hand disassembly, the design of sealing oil groove ensure that connecting shaft can slide up and down in connecting shaft connecting component, another party
Face, which also can guarantee, forms sealing between connecting shaft and connecting shaft connecting component.
