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.

Referring to fig. 1-4, an embodiment of the present invention provides a technical solution: the novel anti-rotation pin shaft comprises a pin shaft 1, a pin shaft baffle plate 2 and a locking disc 5, wherein a positioning hole 3 and a locking hole 6 are formed in the pin shaft baffle plate 2, a rotating disc 4 is embedded in the positioning hole 3, one end of the rotating disc 4 is provided with a locking end 7, the other end of the rotating disc is fixedly welded with the pin shaft 1, and the locking disc 5 is embedded in the locking hole 6.

And a rotating groove is arranged in the positioning hole 3 and is connected with the rotating disc 4 in an embedded manner. The rotating groove is embedded with the rotating disc, so that the limiting rotation of the rotating disc is realized.

The diameter of the locking disc 5 is larger than that of the rotating disc 4, and the locking disc 5 is connected with the locking end head 7. The locking dish is greater than the rotary disk, can realize that the locking dish links up the locking end, realizes spacing locking.

The locking disc 5 is provided with a screw head, the locking hole 6 is a screw hole, and the screw head is in threaded connection with the locking hole 6. The screw head is in threaded connection with the screw hole, so that the threaded transmission of the locking disc can be realized, and the purpose of locking the locking end head is achieved through the threaded transmission.

And a rubber gasket is bonded on the embedding disc surface of the locking disc 5, and the rubber gasket is bonded and fixed with the embedding disc surface of the locking disc 5 through strong glue. When the locking disc is connected with the locking end, the rubber gasket enhances the friction force on the locking end.

The working principle is as follows: because round pin axle 1 is fixed with rotary disk 4 on the limit baffle 2, round pin axle 1 can rotate with rotary disk 4 together, when fixing round pin axle 1, only need to lock spiral shell head and the gomphosis of locking hole 6 on the dish 5, through rotating locking dish 5, realize that locking dish 5 carries out screw thread transmission, because the diameter of locking dish 5 is greater than rotary disk 4, make locking dish 5 link up with locking end 7 on the rotary disk 4, thereby reach the effect to locking dish 5 locking, locking of locking dish 5, thereby realize fixing round pin axle 1, the loss of producing when having avoided round pin axle 1 to rotate, lead to spacious volume too big, to the problem of loss equipment.

The utility model discloses a pin 1, a pin baffle 2, a positioning hole 3, a rotating disc 4, a locking disc 5, a locking hole 6, a locking end 7, the components are all universal standard components or components known by technicians in the field, the structure and principle of the locking hole are all known by technicians through technical manuals or through conventional experimental methods, the utility model solves the problems that the prior pin structure is limited, uncontrollable rotation can be generated during use, loss is generated during rotation, the excessive spaciousness is caused, and equipment is damaged, the utility model can lock the rotating disc through the locking structure of the pin, the fixing of the rotating disc realizes the fixing of the pin due to the welding structure between the rotating disc and the pin, the free rotation of the pin and the loss generated during rotation are effectively avoided, resulting in a problem that the spaciousness is too large to damage the equipment.

The basic principles and the main features of the invention and the advantages of the invention have been shown and described above, it will be evident to those skilled in the art that the invention is not limited to the details of the foregoing illustrative embodiments, but that the invention may be embodied in other specific forms without departing from the spirit or essential characteristics of the invention.
