Description
[ technical field ] A method for producing a semiconductor device
The utility model relates to a technical field of nut, especially combination lock nut's technical field.
[ background of the invention ]
The nut is a nut, is screwed together with a bolt or a screw rod to play a role in fastening, is divided into carbon steel, stainless steel, nonferrous metal and other types according to different materials by an element which is necessary for manufacturing machinery, is a fixing tool, and is provided with a hole in the center and threads on the inner side of the hole. Nuts are often used in conjunction with appropriately sized screws to secure the respective engagement portions. If the nut is loosened by vibration or other environmental factors, the relevant part can be further reinforced by using glue or pins. The nut is hexagonal more, and secondly for the square, current nut simple structure, nut fastening effect is not good, uses easily not hard up under the influence of factors such as vibrations for a long time.
[ Utility model ] content
The utility model aims at solving the problem among the prior art, providing a combination lock nut for construction scaffolding, through the fastening force between two nuts reinforcing and the bolt of mutually supporting, improve locking performance not hard up.
In order to realize the purpose, the utility model provides a combination lock nut for construction scaffolding, including first nut, second nut, first nut be regular hexagonal prism type, the vertical first nut screw thread chamber that is equipped with in first nut inside center, second nut upper end be regular hexagonal prism type, second nut lower extreme be equipped with the second nut screw rod, second nut screw rod lateral wall be equipped with can with first nut screw thread chamber complex second nut screw rod external screw thread, the vertical second nut screw thread chamber that is equipped with in second nut inside center, the second nut screw rod locate first nut screw thread intracavity.
Preferably, a spring washer is arranged between the upper end of the first nut and the second nut, and the spring washer is sleeved on the second nut screw.
Preferably, when the connection between the first nut and the second nut is tightened, the spring washer is compressed to the lowest limit height, and at this time, the horizontal height of the lower end surface of the screw rod of the second nut is flush with or slightly higher than the horizontal height of the lower end surface of the first nut.
Preferably, the height of the second nut screw is longer than the depth of the first nut threaded cavity.
Preferably, the lower end face of the first nut is uniformly provided with a plurality of anti-skid grains.
The utility model relates to a combination lock nut's beneficial effect for construction scaffolding: the utility model discloses a combine two nuts, through screwing up two nuts after, mutually support the fastening force between reinforcing and the bolt between the nut, improve locking performance of moving, through set up spring washer between the nut, improve nut anti-seismic performance, reduce not hard up probably.
