Detailed Description

Referring to fig. 1 to 3, in an embodiment of the present utility model, an explosion-proof movable joint includes a movable joint main body composed of a first joint body 1, a second joint body 2 and a sealing gasket 3. An auxiliary fixing mechanism 4 for improving the assembly stability is arranged between the first connector body 1 and the second connector body 2.

The auxiliary fixing mechanism 4 comprises a collar 41, a plurality of raised strips are arranged on the outer ring shell wall of the collar 41 along the circumferential direction, a plurality of movable cavities are formed in the shell wall of the collar 41, and the movable cavities correspond to the corresponding raised strips respectively. The corresponding arrangement between the movable cavity and the raised strips makes the vertical plate 42 pass through the raised strips on the top shell wall of the movable cavity, and guides and supports the movement of the vertical plate 42 through the raised strips.

Each movable cavity is movably connected with a vertical plate 42, and the top of the vertical plate 42 extends out of the convex strips and is fixedly connected with a clamping strip 43. Arc-shaped clamping blocks are arranged at the bottoms of the two ends of the clamping strip 42.

The top and bottom of the collar 41 are movably connected with adjusting members, and a plurality of adjusting members are movably connected to corresponding risers 42 respectively. The two ends of the adjusting piece are arranged, and then when the first connector body 1 and the second connector body 2 are loaded, the adjusting piece at the two ends is synchronously extruded and driven along with the assembly of the second connector body 2, and then the corresponding vertical plate 42 is driven to be stably adjusted.

The connector body 1 comprises a polygonal ring body 11, an outer pattern sleeve 12 is integrally arranged at the top and the bottom of the polygonal ring body 11, and a plurality of guide strips 13 are arranged on the outer ring of the outer pattern sleeve 12 in the lower direction along the circumferential direction. The peripheral wall of the first polygonal ring body 11 is provided with an annular groove for clamping and limiting.

The second connector body 2 comprises a second polygonal ring body 21, an inner thread sleeve 22 is integrally arranged at the bottom of the second polygonal ring body 21, and a convex ring 23 used for loading the sealing gasket 3 is fixedly connected inside the inner thread sleeve 22. The peripheral wall of the second polygonal ring body 21 is also provided with an annular groove for clamping and limiting.

A plurality of guide grooves are formed in the inner ring shell wall of the collar 41 along the circumferential direction, and the guide grooves are connected with the guide strips 13 in a sliding manner. The setting scope of guide way and gib block 13 is unanimous, through the setting of guide way and gib block 13, and then conveniently assembles auxiliary fixing mechanism 4.

The adjusting member comprises adjusting rods 44 inserted in the corresponding movable cavities, and one ends of the plurality of adjusting rods 44 positioned outside the lantern ring 41 are commonly connected with a fixed ring 45. The vertical plate 42 is provided with a plurality of inclined grooves, a convex rod is connected in the inclined grooves in a sliding way, and one end of the convex rod, which is far away from the inclined grooves, is fixedly connected to a corresponding adjusting rod 44. The movement of the adjustment lever 44 in turn moves the corresponding cam in the chute, causing the riser 42 to displace therewith.

Each adjusting rod 44 is sleeved with a fixed disc and a spring, wherein the fixed disc is welded on the outer ring shell wall of the adjusting rod 44, one end of the spring is arranged on the fixed disc, and the other end of the spring is arranged on the inner wall of the corresponding movable cavity. The arrangement of the spring enables the auxiliary fixing mechanism 4 to automatically reset under the condition of non-external force extrusion, and the movable joint main body is convenient to detach.

The working principle of the utility model is as follows: when the movable joint main body is assembled, the sealing gasket 3 is firstly placed on the convex ring 23 inside the inner thread sleeve 22, then the auxiliary fixing mechanism 4 is sleeved on the outer thread sleeve 12 below the first joint body 1 in a mode that the guide strip 13 is sleeved on the guide groove, and then the first joint body 1 is in threaded connection with the second joint body 2.

When the first connector body 1 is in threaded connection with the second connector body 2, the second polygonal ring body 21 in the second connector body 2 is continuously close to the adjusting piece in the auxiliary fixing mechanism 4 along with the threaded progress of the second connector body 2 in the first connector body 1. After the second polygonal ring 21 contacts the adjusting member, the second polygonal ring 21 extrudes the fixing ring 45 of the lower adjusting member along with the continuous progress of the second connector 2, so as to drive the adjusting rod 44 to displace. Along with the movement of the adjusting rod 44, the corresponding vertical plate 42 is moved, the corresponding clamping strip 43 is driven to move, after the second connector body 2 is loaded, the clamping strip 43 clamps and limits annular grooves of the first polygonal ring body 11 and the second polygonal ring body 21 by extruding the adjusting piece, so that the stability of connection between the first connector body 1 and the second connector body 2 is further improved.
