Detailed Description
The following further describes embodiments of the present invention with reference to the drawings.
In the drawings 1-3, the device comprises a cylinder 1, a swing rod moving space 1-1, a connecting shaft 2, a swing rod 3, a connecting rod 4, a clamping bracket 5, a clamping block 6, a mounting seat 7, a bolt 8, a gasket 9, a positioning pin 10, a screw 11 and the like.
As shown in fig. 1 to 3, the invention relates to a rail locking device, which comprises an installation base 7, wherein a top plate of the installation base 7 is provided with a cylinder 1, a piston rod of the cylinder 1 is fixedly connected with a connecting shaft 2, the lower end of the connecting shaft 2 extends into a guide hole arranged at the lower part of the installation base 7, and the surfaces of two sides of the middle part of the connecting shaft 2 are respectively and rotatably connected with a swing rod 3.
The lower part both sides of mount pad 7 rotate respectively and set up connecting rod 4, and the upper end of two connecting rods 4 is connected with corresponding swinging arms 3 is articulated respectively, the lower extreme fixed connection of connecting rod 4 presss from both sides tight support 5, presss from both sides and installs clamping block 6 on the tight support 5.
The front and back surfaces of the connecting shaft 2 are respectively provided with swing rod moving spaces 1-1, and the swing rod 3 is rotatably connected with the connecting shaft 2 through a rotating shaft 12. The upper part and the lower part of the swing rod moving space 1-1 are constructed into flaring structures. When the swing rod 3 rotates, the swing rod 3 and the swing rod moving space 1-1 can freely and reliably rotate, and the swing rod 3 cannot interfere with the connecting shaft 2 when rotating.
The upper part and the lower part of the mounting seat 7 are respectively provided with a bolt 8, and a gasket 9 is sleeved on the bolt 8. The mounting seat 7 of the invention is fixedly connected with the movable trolley through a bolt 8.
Further, in order to realize reliable positioning of the mounting seat 7 in use, the mounting seat 7 is further provided with a positioning pin 10, and the positioning pin 10 is connected with the mounting seat 7 in positioning when working.
