Abstract
The present invention relates to a screw assembly and a using method thereof, wherein the screw assembly has a rivet function and is matched with a withdraw-stop clamping spring in a nut slope shape. The present invention at least comprises a bolt, a nut and a withdraw-stop clamping spring positioned on the middle of the thread clearance of the nut and the bolt. The components of the present invention can be conveniently positioned in the original engineering component which needs the riveted connection of rivets by exclusive-use tools. The present invention provides a condition for the combination of the assembly with a bolt and a nut and the function of the riveted connection of rivets, is suitable for the non-disassembly mutual connection or reinforcement of large-size or huge-size engineering components, and is particularly suitable for replacing the inconvenient technology and means of the riveting connection of rivets in the occasions of the on-site construction.
Description
Technical field:
The present invention relates to extremely using method of fastener constructions technology.
Background technique:
At present, when building large-scale or huge non-removable steel structure shape part, for example: steelframe bridge, steelframe high tower (TV signal launching tower) and steel structure superelevation floor room, normally adopt the technological means of rivet to realize the connection of associated components and reinforcing, because this traditional method has been brought very big inconvenience to construction, therefore, people have designed the riveting technology that a kind of utilization technology the same with the screw means mode replaces rivet again.
CN2101794U and CN239294Y have disclosed and have adopted the screw conventional fasteners also can realize the tightening technology of rivet.Its deficiency is: the retaining jump ring parts that wherein have only half-turn with the screw thread contact range of bolt, under the sharp pounding situation that takes place frequently, at first be that oneself just might retreat slip in advance, for the loosening function that loses its riveted joint that causes nut and bolt has at last caused disadvantageous condition.
Summary of the invention:
The present invention's purpose: be exactly a kind of improvement project that proposes in order to solve above-mentioned " deficiency ".
In order to realize the object of the invention, intend adopting following technology:
Structural feature of the present invention: in the structure of nut and bolt, set up and to be advanced to the middle retaining jump ring of thread gaps that is positioned at nut and bolt, it is characterized in that: the bottom of above-mentioned retaining jump ring is provided with an anti-skidding wedge angle at least, to assist the retaining jump ring stuck in the middle of the thread gaps of above-mentioned nut and bolt.---the material hardness of above-mentioned retaining jump ring should be greater than the material hardness of bolt.
Fastening using method of the present invention (step): A. is tightened on nut on the oriented bolt; B. in the middle of the retaining jump ring being advanced and makes it to be clamped on the nut and the thread gaps between the bolt that has screwed from the rear of nut.---above-mentioned " chucking " refers to: allow hammer by knocking nail tool (special tool or non-special tool) with in the middle of the screw thread seam of retaining jump ring " stuck " between nut and bolt.
The present invention's characteristics compared with the prior art: set up at least one " anti-skidding wedge angle " on the retaining jump ring because the present invention structurally allows, on fastening using method, make the further propelling of retaining jump ring and stuck (non-dismountable) in the middle of thread gaps by knocking with hammer, add assurance behave with " material hardness difference ", this has created advantageous conditions with regard to then causing becoming flexible between the nuts and bolt for retreat (and bolt produces displacement) of at first preventing retaining jump ring oneself under the situation that is implemented in the sharp pounding that takes place frequently.
Description of drawings:
Topology layout state when Fig. 1 has illustrated that the present invention replaces the fastening relevant connection parts of rivet; Fig. 2 has illustrated the profile unfolded drawing of the critical component among the present invention " nut slope shape loosening-proof jump ring "; Fig. 3 is the left view of Fig. 2; Fig. 4 is Fig. 2 " D-D " sectional drawing.
1: bolt; 2: nut; 3, engineering part A; 4: engineering part B; K: slope shape loosening-proof jump ring; P: hard and sharp anti-skidding wedge angle, a: bolt thread groove angle; B: retaining jump ring bottom section angle.
Embodiment:
Bolt 1 is positioned on engineering part A3 and the engineering part B4, nut 2 is tightened on the bolt 1 routinely, afterwards, with the half round bar shape and the retaining jump ring K of the small skew gradient slightly, precession the thread taper slit between bolt 1 and nut 2 then, is used the special tool with bolt 1 screw thread precession, K screws inwards with this retaining jump ring, the special tool that hits with a hammer is pushed ahead retaining jump ring K again make it stuck in the middle of the thread gaps of nut and bolt.
Retaining jump ring K preferably sets up hard and sharp anti-skidding wedge angle P in design, and preferably more than one: form sawtooth if how anti-skidding wedge angle P arrive, it is convenient on the contrary to make like this, and the skidproof effect meeting when frequent judder better.At this moment, retaining jump ring K bottom section angle b should be less than bolt thread groove angle a, and the leeway that so just has living space allows anti-skidding wedge angle P roll the into thread groove surface of bolt 1.This in prevent most effectively retaining jump ring K taking place frequently under the situation of judder along the thread groove of bolt 1 backward slippage be favourable.---have only half-turn and the most loosening retaining jump ring K loosening displacement to take place as long as prevent, so, have the nut 2 of several circles just not have the possibility of loosening displacement with the screw thread contact range of bolt 1 with bolt 1 with the screw thread contact range of bolt 1.
Be not difficult to find, key of the present invention is: increased " anti-skidding " structure (for non-dismountable creating conditions) of retaining jump ring K, and and then allow in use retaining jump ring K effectively " stuck " (realizing non-dismountable) between the thread gaps of bolt 1 and nut 2.
Claims (4)
