The four-connection-bar mechanism comprises a first fixing bar, a second fixing bar, a first connection bar, a second connection bar, a first connection shaft, a second connection shaft and a third connection shaft. Respective location sleeves are arranged on the first connection shaft, the second connection shaft and the third connection shaft. External threads are arranged at the two ends of the first connection shaft, the second connection shaft and the third connection shaft. The first connection bar is connected with the second connection shaft, the third connection shaft and bolts through bolts and nuts respectively. The second connection bar is connected with the first connection shaft and the second connection shaft through bolts respectively. The door cover is connected with the first fixing bar of the four-connection-bar mechanism through welding, and the second fixing bar is connected with the door frame outer wall through welding.

Summary of the invention
Object of the present invention is exactly the problems referred to above that exist for solving prior art, and a kind of grinding machine four-bar linkage structure sliding door is provided; Reliable in structure of the present invention, it is convenient to open and close, easy accessibility, time saving and energy saving, sealing structure performance is good, is particularly useful for grinding machine or similar devices that a weight is larger.
The technical scheme of technical solution problem of the present invention is:
A kind of grinding machine four-bar linkage structure sliding door, comprise doorframe, door closure, described doorframe is connected with doorframe outer wall by welding, described doorframe is connected with door closure one end, the door closure other end is connected with doorframe outer wall by quadric chain, described quadric chain comprises the first fixed bar, the second fixed bar, first connecting rod, second connecting rod, the first connecting axle, the second connecting axle, the 3rd connecting axle, described the first connecting axle, the second connecting axle, on the 3rd connecting axle, be respectively equipped with positioning sleeve separately, described the first connecting axle, the second connecting axle, the 3rd connecting axle two ends are respectively equipped with external screw thread, first connecting rod by bolt respectively with the second connecting axle, the 3rd connecting axle is connected with bolt, second connecting rod passes through bolt, nut respectively with the first connecting axle, the second connecting axle connects, described door closure is connected with the first fixed bar in four connecting rods by welding, the second fixed bar is connected with doorframe outer wall by welding.
Described doorframe and door closure contact surface place are provided with sealing mat.By sealing mat stress deformation, guarantee that whole door has good closure.
Described doorframe is provided with screwed hole, and door closure is provided with connecting hole, and doorframe is connected by the bolt coordinating with screwed hole with door closure one end.
Described door closure is provided with handle at the external surface that connects a side near bolt.
Beneficial effect of the present invention:
1. reliable in structure of the present invention, open, close conveniently, convenient disassembly, time saving and energy saving, doorframe and door closure joint face place are provided with sealing mat, by sealing mat stress deformation, guarantee whole door good seal performance, be particularly useful for grinding machine or similar devices that access door weight is larger.
2. structure of the present invention is to be fixed by welding on the outer wall at place, place, applicability is wide, adopt connecting rod push-pull structure, whole opening or closing in process do not need people to bear very large power, alleviated operator's labour intensity, also improved operating efficiency, so especially applicable for the larger occasion of access door weight.
3., together with door closure of the present invention is bolted with doorframe, by four-bar linkage structure, carry out opening or closing of control gate, due to linkage motion there is very large flexibility, so opening or closing of whole door also has very large flexibility.
4. passing through the handle of door closure external surface, and quadric chain, just can easily door be opened and closed.
