The stainless steel spring nut
Technical field
The utility model belongs to technical field of fastening, especially relates to a kind of stainless steel spring nut.
Background technique
Existing nut is a kind of important fastening piece accessory, and it mainly acts on and is fastening, but service time one is long; Existing nut is in vibrational state for a long time on the object of motion, tend to produce loosening, thereby easy to wear, come off; Often lead to major accident, cause unnecessary loss, particularly some traditional connection sets; Its requirement fastening and compacting pressure is high, if adopt the electric welding weldering dead, in the future after the gap enlargement; Can not tighten again admittedly, if adopt latch fastening, same being prone to become flexible again.In order to address this problem, modular nut has appearred on the market, and it comprises nuts and washers; Packing ring be located in nut and between the fastening object and be arranged on the screw rod jointly; This modular nut, when having solved the bolt assembly and having tightened, nut be difficult for scratch fastening external surface of objects; Reduced simultaneously nut and the gap between the fastening object, certain anti-loosening and effect that comes off is arranged.
Not enough below but above-mentioned modular nut exists: at first the operator only is being used under the situation of packing ring, and it could realize reducing friction, and plays certain anti-loosening effect simultaneously, makes that the operator feels more loaded down with trivial details in the real life, easy omission; Secondly, its anti-loosening effect does not reach locking requirement in high request and high-precision working environment.
The model utility content
The purpose of the utility model is to provide a kind of anti-loosening falling-off effect good stainless steel spring nut for the deficiency that solves above-mentioned existing technology.
To achieve these goals; The stainless steel spring nut that the utility model designed comprises the nut through hole of stainless steel nut and integral type, and stainless steel nut upper surface is a ledge structure; Crowning is provided with the screwer groove; The matching thread cutter carries out degree of tightness to be regulated and dismounting, and said stainless steel nut is provided with spring groove, and spring groove is provided with stainless steel spring.
The bolton place of fastening object need cooperate with other objects when installing, in order to improve the sealing of installation place, said stainless steel nut upper surface is all parallel rib that is provided with except that crowning.
The stainless steel spring nut that the utility model obtains is compared the advantage that is had with existing technology and is: the all-in-one-piece design of the utility model; Operate easylier, wherein the design of stainless steel spring has reduced nut loosening; The phenomenon of at utmost having avoided nut to come off; Farthest reduced simultaneously nut and the wearing and tearing between fastening, stainless steel nut upper surface is all parallel rib that is provided with except that crowning, has improved the sealing of installation place.

Embodiment
Below in conjunction with accompanying drawing and embodiment the utility model is further specified.
Embodiment 1:
Stainless steel spring nut as depicted in figs. 1 and 2, that the utility model provides comprises the nut through hole 2 of stainless steel nut 1 and integral type; Stainless steel nut 1 upper surface is a ledge structure, and crowning is provided with screwer groove 5, cooperates " word " screwer to carry out degree of tightness and regulates and dismounting; Stainless steel nut 1 is provided with spring groove 4; Stainless steel spring 3 is fixedly mounted on the spring groove 4, and stainless steel spring 3 contacts with fastening of institute during use, along with the variation of stainless steel nut 1 degree of tightness; Stainless steel spring 3 synchronization telescopes guarantee that all the time stainless steel spring 3 withstands institute's fastener surface of contact, reduce the space and prevent to become flexible.
Embodiment 2:
Like Fig. 3 and shown in Figure 4; Described model utility of present embodiment and embodiment 1 are described roughly the same; But when the bolton place of fastening object need cooperate with other objects when installing; In order to improve the sealing of installation place, said stainless steel nut 1 upper surface is all parallel rib 6 that is provided with except that crowning.
