Detailed Description
The technical solutions in the embodiments of the present invention will be clearly and completely described below with reference to the drawings in the embodiments of the present invention, and it is obvious that the described embodiments are only a part of the embodiments of the present invention, and not all of the embodiments. All other embodiments, which can be derived by a person skilled in the art from the embodiments given herein without making any creative effort, shall fall within the protection scope of the present invention.
Referring to fig. 1-3, an embodiment of the present invention is shown: the anti-loosening screw for fixing the square pile comprises a screw cap 1, wherein a cross groove 2 is fixedly formed in the screw cap 1, a screw 3 is fixedly welded at the lower end of the screw cap 1, threads 4 are formed at the lower end of the screw 3, anti-rust paint is coated on the outer surfaces of the screw cap 1 and the screw 3, and the anti-rust paint is coated on the outer surfaces of the screw cap 1 and the screw 3 to prevent the device from rusting and loosening;
the bottom end of the screw rod 3 is fixedly welded with a cutting blade 5, the screw rod 3 is connected with a fixed block 6, the fixed block 6 is provided with a spring 7, the upper end of the spring 7 is fixedly connected with the fixed block 6, the lower end of the spring 7 is fixedly connected with a fixed plate 8, the spring 7 is sleeved on the screw rod 3, the screw rod 3 is arranged into a telescopic connecting framework through the spring 7, and the spring 7 is arranged, so that the impact force generated by the device during the working of a machine can be effectively reduced, the device is prevented from loosening, the device is prevented from falling off, and the working efficiency is;
the screw 3 is provided with the fixing plate 8, the fixing plate 8 is provided with the glue injection port 9, the fixing plate 8 is of a U-shaped structure, the fixing plate 8 is provided with a notch, the inner side size of the notch is the same as the outer side size of the screw cap 1, the fixing plate 8 and the screw cap 1 form an embedded connection structure, the screw cap 1 is embedded into the fixing plate 8 through the embedded structure of the screw cap 1 and the fixing plate 8 and the stress of the spring 7, so that the screwdriver is more stably inserted into the cross groove 2, the screwdriver is not easy to slide out of the cross groove 2 due to uneven rotating force, and the construction speed is delayed; four groups of glue injection ports 9 are formed in the fixing plate 8, the four groups of glue injection ports 9 are uniformly distributed on the fixing plate 8, and glue can flow onto the screw rods 3 through the glue injection ports 9, so that firmness of the device is improved, and the device is prevented from loosening;
the bottom of fixed plate 8 is provided with anti-skidding thorn 10, and anti-skidding thorn 10 evenly sets up in the bottom of fixed plate 8, through being provided with anti-skidding thorn 10 for this device can be more firm installs on the machine, avoids causing not hard up and obscission.
The working principle is as follows: when the device is used, a screwdriver is inserted into a cross-shaped notch 2 formed in a nut 1, and a cutting edge 5 at the bottom end of a screw rod 3 enters the inside of an object through rotating force;
subsequently, the screw thread 4 on the screw rod 3 can continuously enter the object through the rotation of the screwdriver on the cross groove 2, the screw rod 3 can quickly penetrate into the object due to the fact that the screw thread 4 can easily penetrate through the object, and the friction force of the screw thread 4 is larger, so that the screw and the object are firmer, and the loosening and falling are not easy to occur;
because the screw 3 continuously enters the object, the fixing plate 8 connected to the screw 3 is to be attached to the surface of the object, at the moment, glue is injected into the screw 3 through the glue injection port 9 formed in the fixing plate 8, the whole screw 3 contains the glue along the spiral shape of the thread 4, the distance between the nut 1 and the fixing plate 8 is slowly shortened through the rotation of the screwdriver, the spring 7 is mounted on the fixing plate 8, the nut 1 is close to the fixing plate 8 due to the continuous stress of the spring 7, and the force generated by the vibration of the machine can be decomposed due to the spring 7, so that the loosening of the screw is avoided; the anti-skid thorns 10 arranged at the lower end of the fixing plate 8 are immersed into the object by screwing the screw, and the anti-skid thorns 10 are sharp, so that the screw can more firmly enter the object when the anti-skid thorns 10 apply force to the stress surface;
finally, when the whole screw can not be screwed into the object, the screwdriver is pulled out from the cross-shaped groove 2 on the screw cap 1.
It will be evident to those skilled in the art that the invention is not limited to the details of the foregoing illustrative embodiments, and that the present invention may be embodied in other specific forms without departing from the spirit or essential attributes thereof. The present embodiments are therefore to be considered in all respects as illustrative and not restrictive, the scope of the invention being indicated by the appended claims rather than by the foregoing description, and all changes which come within the meaning and range of equivalency of the claims are therefore intended to be embraced therein. Any reference sign in a claim should not be construed as limiting the claim concerned.
