Detailed Description

The technical solutions in the embodiments of the present invention will be described clearly and completely with reference to the accompanying drawings in the embodiments of the present invention, and it is obvious that the described embodiments are only some embodiments of the present invention, not all embodiments. Based on the embodiments in the present invention, all other embodiments obtained by a person skilled in the art without creative work belong to the protection scope of the present invention.

Please refer to fig. 1-4, the utility model provides a technical scheme, a be used for orbital quick closing device of pipeline circumference crawler, including pressing portion 30 and eccentric handle 50, still include chassis 10 and sleeve 20, annular groove 11 has been seted up to the upper surface on chassis 10, sleeve 20 can be dismantled fixed cover and connect in the bottom of pressing portion 30, the bottom of sleeve 20 slides and cup joints in the outer fringe of annular groove 11 inner chamber, the center of rotation department of eccentric handle 50 is provided with pivot 70, pivot 70 rotates and has cup jointed the connecting rod body 40, fixed connection can be dismantled with the central point of chassis 10 behind the center that the portion 30 was kept through pressing to the bottom of the connecting rod body 40, the periphery that the portion 30 that keeps corresponding connecting rod body 40 bottom is provided with cylinder die cavity 33, reset spring 60 has been cup jointed to the connecting rod body 40 periphery in the cylinder die cavity 33.

In this embodiment, the bottom of the pressing portion 30 is sleeved with the sleeve 20 through a screw.

In this embodiment, a threaded through hole 12 is formed in the center of the chassis 10 along the vertical direction, and an external thread that is in threaded sleeve connection with the threaded through hole 12 is disposed at the bottom end of the connection rod body 40.
