Detailed Description

Figure 1 the utility model discloses a structural schematic, spherical tank pull rod includes pterygoid lamina 1, pole I2, baffle 6, elastic joint 3 and pole II 4. The pole I2 and the pole II 4 are cylindrical, and two planes are processed to one end, and with 1 welding of pterygoid lamina, as shown in figure 2, the other end processing external screw thread is convenient for be connected with elasticity festival 3, and it has keyway 9 to process simultaneously, as shown in figure 3. In order to ensure the synchronous tightness of the two rods, the screw thread directions of the rod I2 and the rod II 4 are opposite. The baffle 6 is positioned at two ends of the elastic joint 3 and is provided with a convex key 8 matched with the key groove 9. The elastic joint 3 is tubular, and internal threads matched with the rod I2 and the rod II 4 are processed at two ends of the elastic joint. The middle part of the elastic joint 3 is provided with a mounting hole 5, and the round hole is used for fixing the clamping apparatus, so that the elastic joint 3 can be conveniently rotated, and the tightness of the spherical tank pull rod can be adjusted. After the elastic joint 3 is adjusted, the elastic joint 3 is connected with a screw 7 to fasten the baffle 6. To facilitate the tightening operation of the screws 7, a plurality of concentric bolt holes may be machined in the baffle plate 6.

When the spherical tank pull rod is used, the convex key 8 of the baffle 6 is matched with the key groove 9, the baffle 6 is sleeved into the rod, then the elastic joint 3 is sleeved into the mounting hole 5 through the connecting rod I2 and the rod II 4, the elastic joint 3 is rotated, and the adjusting pull rod is tensioned. After the pull rod is tensioned, the micro-adjustment elastic joint 3 rotates, so that the bolt hole in the baffle 6 is consistent with the center line of the blind hole of the internal thread at the end part of the elastic joint 3, and the screw 7 is screwed in.

Threaded holes are processed in wing plates at two ends of the pull rod, the pull rod can be fixedly connected with the upper lug plate and the lower lug plate of two adjacent struts of the spherical tank through pins or bolts respectively, the elastic joint 3 is rotated, the length of the pull rod of the spherical tank is adjusted, so that the transverse load of the spherical tank is borne, and the use safety of the spherical tank is guaranteed.

In order to avoid the adverse effect of the mounting hole 5 on the strength of the elastic joint 3, the square or the hexagon protruding from the outer circle of the elastic joint 3 can be replaced, as shown in fig. 4, the square is a solid line, and the hexagon is a two-dot chain line, so that the effect of conveniently rotating the elastic joint 3 can be achieved.

For the convenience of processing and stability of the rod, one key groove 9 is preferably adopted on the rod I2 and the rod II 4. Baffle 6 can be installed in the one end of elastic joint 3, also can install at the both ends of elastic joint 3, and both kinds of circumstances all can play the effect of restriction elastic joint 3 rotation.

The spherical tank pull rod can adjust the tightness of the pull rod by utilizing the matching of the two rods with opposite thread directions and the elastic joint 3. Adopt screw 7, convex key 8 and keyway 9 structure, link elasticity festival 3 and two poles as an organic whole to restriction elasticity festival 3's rotation prevents that elasticity festival 3 from loosening. After the spherical tank is used for a certain time, the original pretightening force of the pull rod is loosened, the screw can be loosened, and the elastic joint 3 is rotated again to adjust the pretightening force of the pull rod, so that the pull rod is in a prestressed state, and the stability and the safety of the spherical tank are ensured.

The utility model discloses simple structure, convenient to use, 3 middle part processing mounting holes of elasticity festival or square bulge make things convenient for the spherical tank in the use, in good time regulation pull rod's elasticity, baffle 6 provides the safety guarantee for elasticity festival 3, makes the spherical tank atress even, ensures the safety of spherical tank.
