specific Embodiment approach 1

[0021] Specific implementation mode one: combine Figure 1 to Figure 3 Describe this embodiment, the anti-false screwing embedded bolt ball joint described in this embodiment includes a sphere 1, a sleeve 2 and a tubular rod 3, one end of the sleeve 2 is connected to the sphere 1, and the other end of the sleeve 2 One end is rotatably connected with the tubular rod body 3 .

specific Embodiment approach 2

[0022] Specific implementation mode two: combination figure 2 To illustrate this embodiment, the outer surface of the sphere 1 in this embodiment is provided with a blind hole, and a screw 1 - 1 is provided in the blind hole, and the screw 1 - 1 is used to connect with one end of the sleeve 2 . The sphere 1 is made of a steel ball to cut out the screw, and the screw can be drilled at any angle to adapt to the connection of space rods in any direction.

[0023] Other components and connections are the same as those in the first embodiment.

specific Embodiment approach 3

[0024] Specific implementation mode three: combination figure 2 To illustrate this embodiment, the sleeve 2 in this embodiment includes a threaded sleeve 2-1, a limiter 2-2, a hexagonal column section 2-3 and a rod end fixing member 2-4; the threaded sleeve 2- 1. The limit piece 2-2, the hexagonal column section 2-3 and the rod end fixing piece 2-4 are connected in sequence from left to right to form a whole. The threaded pipe sleeve 2-1 is provided with internal threads, and the threaded pipe sleeve 2-1 is set On the screw rod 1-1, a rod end fixing member 2-4 is embedded in one end of the tubular rod body 3.

[0025] Other compositions and connections are the same as those in Embodiment 1 or 2.

Abstract

An anti-false twisting embedded bolt ball joint. The invention relates to a bolt ball joint. In order to solve the problem that the existing bolt ball joints cannot solve the false twisting phenomenon, the invention further proposes an anti-false twisting embedded bolt ball joint. . The invention comprises a sphere, a sleeve and a tubular rod, one end of the sleeve is connected with the sphere, and the other end of the sleeve is rotatably connected with the tubular rod. The bolt ball joint described in the present invention can meet the assembly requirements of various angles and directions, and has a flexible structure; after the sleeve and the sphere are tightened, it can be determined by observing the relative position between the limiter and the horizontal plane of the sphere or by observing the position of the embedded screw through the observation hole Whether the sleeve is tightened is more intuitive.

Description

technical field [0001] The invention relates to a bolt ball joint, in particular to an anti-false screwing embedded bolt ball joint, which belongs to the technical field of construction engineering. Background technique [0002] Bolt ball joints are suitable for connecting steel pipe members and are mainly used in grid structures. In space grid structures, bolt ball joints are widely used. The traditional bolted ball joint uses a socket with a hole to connect the bolt with a chute, and checks whether it is tightened by a pin passing through the hole and the chute. However, the pin is prone to breakage during the twisting process. It is not possible to confirm whether false screwing has occurred. Based on the above, the invention patent with the publication number CN205171694U discloses a space grid structure pinless bolt connection node Contents of the invention [0003] In order to solve the problem that the existing bolt ball joints cannot solve the false screwing phen...
