Abstract
The utility model provides a screw of prevention not hard up type, including the screw main part, the screw main part is equipped with the screw cap soon, the screw of locking type in advance still includes the spring, the screw main part runs through the spring, the body of screw main part is equipped with the screw thread, the screw thread to it is equipped with the sealing washer to revolve cap extending direction. Has the advantages that: the spring produces tensile force in the screwing process, and the looseness of the spring is avoided. The looseness of the screw is reduced, the tightness of the screw connection is improved, and the situation that the screw cannot be opened due to the fact that moisture rusts the screw in the gap is reduced.
Description
Technical Field
The utility model relates to the field of machinary, especially, relate to a screw that can carry out locking type in advance.
Background
The equipment has big bright spot volume vibrations in the use, can make the screw take place to become flexible, impairs the life-span of machine, therefore needs to provide a technical scheme to solve such technical problem.
Disclosure of Invention
The utility model provides a screw of prevention not hard up type, the aim at of this device of design and development reduces not hard up of screw to increase screwed connection's leakproofness, invade the dead screw of moisture rust in the reduction clearance and lead to the screw can't open.
The utility model provides a following technical scheme: the utility model provides a screw of prevention not hard up type, includes screw main part 1, screw main part 1 is equipped with revolves cap 2, the screw of locking type still includes spring 3 in advance, screw main part 1 runs through spring 3, the body of screw main part 1 is equipped with screw thread 4, screw thread 4 to 2 extending direction of cap soon are equipped with sealing washer 5.
The utility model has the advantages that: with this screw and threaded hole connection, sealing washer 5 has increased the leakproofness of threaded hole, has reduced moisture and has flowed into in the clearance of screw from the external world, reduces the risk of screw corrosion. The spring produces tensile force in the screwing process, and the looseness of the spring is avoided. The looseness of the screw is reduced, the tightness of the screw connection is improved, and the situation that the screw cannot be opened due to the fact that moisture rusts the screw in the gap is reduced.
Drawings
Fig. 1 is a schematic structural view of a pre-loosening prevention screw according to the present invention.
Detailed Description
The invention is further described with reference to the following detailed description of embodiments and drawings.
In fig. 1: the screw comprises a screw body 1, a screw cap 2, a spring 3, threads 4 and a sealing ring 5.
The utility model provides a screw of prevention not hard up type, includes screw main part 1, the welding of 1 one end of screw main part has cap 2 soon, the screw of locking type still includes spring 3 in advance, screw main part 1 runs through spring 3, the body of screw main part 1 is equipped with screw thread 4, screw thread 4 to 2 extending direction of cap soon are equipped with sealing washer 5. The screw main body 1 is provided with a groove, and the sealing ring 5 is embedded into the groove, so that the purpose of fixing the sealing ring 5 is achieved. With this screw and threaded hole connection, sealing washer 5 has increased the leakproofness of threaded hole, has reduced moisture and has flowed into in the clearance of screw from the external world, reduces the risk of screw corrosion.
