Abstract
The present invention relates to a screw component with rivet function and matched nut domatic retreat-stopping jump ring and its application method. Its composition at least includes bolt and nut, and retreat-stopping jump ring positioned in the screw-thread gap of nut and bolt, and they can be conveniently positioned in the engineering component which originally required for riveting by rivet by utilizing special tool, so that said invented 'bolt-nut' combined component also can implement rivet-riveting function.
Description
The present invention relates to fastener technology.
At present, " screw--nut " class fastening piece on the market, its structure all is that adapted can advance the nut that (screwing) can move back (unscrewing) on bolt, if pad spring washer again when screw means, then can play certain retaining effect to the nut that screws, but when brute force (be actually and increase some power slightly) turn nut, nut still can be unscrewed and be withdrawed from bolt.
Therefore, existing " screw--nut " class fastening piece is the function that does not possess rivet (non-dismountable) associated components, unless after nut is tightened on the bolt, adopt the method for metal solder that the nuts and bolt weldering is lived again.This can play the retaining effect to the nut that screws arbitrarily, yet this can make troubles to constructing operation naturally.
For this reason, when building large-scale or huge non-removable steel structure shape part, normally adopt the technological means of rivet to realize the connection of associated components and reinforcing, for example: steelframe bridge, steelframe high tower (TV signal launching tower) and steel structure superelevation floor room (U.S.'s hundred floor World Trade Organization mansions), and the common building of the steel frame construction that develops rapidly (construction speed is fast), or the like.
Obviously, usually connecting when reinforcing large-scale or huge non-removable steel structure shape part, pure metal welding (electric welding or the gas welding) technological means of constructing more convenient (the top layer welding--intensity is limited) and existing " screw--nut " class fastening piece (detachably), all be difficult to get involved.
If in the above-mentioned engineering structure, this should be optimal can to adopt common " bolt--nut " tightening technology means to replace the rivet technology, especially in the very big on-the-spot non-removable rivet construction stage of engineering work load, people are rivet technology of not wishing to adopt suitable trouble.Yet to adopt it, be reluctantly and be forced to fully.
Therefore, if manage to allow common " bolt--nut " fastener technology also can take into account the function (it could be dismantled afterwards) of non-removable rivet, become people's research objective unless destroyed the structure of bolt or nut.
Purpose of the present invention has a solution of same characteristic features when allowing " screw--nut " class fastening piece also can possess with rivet in order to address the above problem, that is: allow the nut that is tightened on the bolt possess non-removable " function ".
The present invention is achieved in that
Its composition comprises at least: by screw bolt and nut, and the middle slope shape loosening-proof jump ring of thread gaps that is positioned at nut and bolt.
In addition: in order to increase the friction dynamics between this retaining jump ring and the bolt thread groove, the way that can set up anti-skidding wedge angle on the retaining jump ring is arranged, the way that sliding wedge angle in the air is also arranged: when retaining jump ring bottom was provided with at least one anti-skidding wedge angle, the section angle of retaining jump ring bottom should be less than the angle of bolt thread groove (purpose be to allow anti-skidding wedge angle have when the pressurized roll the into leeway, space of bolt thread groove); When any wedge angle was not established in retaining jump ring bottom, the section angle of retaining jump ring bottom should be slightly larger than or equal the angle (purpose is to allow the two be convenient to swelling when pressurized) of thread groove; The material hardness that the material hardness that this retaining jump ring is selected for use should be selected for use greater than bolt; Any end in two ends of nut thread hole is the taper state of outside enlarging.
At least the step that comprises in its using method has: A. is tightened on nut on the oriented bolt.B. in the middle of the slope shape loosening-proof jump ring being advanced and is clamped on the nut and the thread gaps between the bolt that has screwed from the rear of nut.
In addition, slope shape loosening-proof jump ring wherein, preferably by special tool with its propelling and be clamped in the middle of the nut and the thread gaps between the bolt that has screwed.Certainly, using hammer also can force this retaining jump ring to reach the purpose of propelling and chucking by knocking nail
The present invention's characteristics compared with the prior art:
1. because the present invention has adopted nut slope shape loosening-proof jump ring, and the anti-skid structure of preventing this jump ring pine to move back under judder is to be implemented under the situation that adopts normal screws structural group component, also can take into account the function of " rivet " and create condition.
2. because many troubles have been reduced for the present invention gives many site operation occasions of " rivet " riveting technology means that must adopt in above-mentioned " 1 ", reduce construction cost significantly and created condition.
3. owing to above-mentioned " 1 ", the series product for the present invention has expanded normal screws structural group component make the update product that oneself becomes " rivet " create condition again simultaneously.
Work (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.
Bolt " 1 " is positioned on engineering part A " 3 " and the engineering part B " 4 ", nut " 2 " is tightened on the bolt " 1 " routinely, afterwards, with half round bar shape and slightly precession the thread taper slit of retaining jump ring " K " between bolt " 1 " and nut " 2 " of the small skew gradient, at last, use special tool, this retaining jump ring " K " is screwed inwards get final product with bolt " 1 " precession.Perhaps, using that nail and hammer strike retaining jump ring " K " inwards also is feasible tightly, and this is that another retaining to nut " 2 " more simple but that bother screws operation scheme.
From all accompanying drawings, be not difficult to find out, after this, if desire with the anti-phase back-out of nut " 2 ", is impossible.Because firmly desire screws out nut " 2 ", the screw thread of nut " 2 " will be expanded by the retaining jump ring " K " of slope shape and block tightly more; Conversely, retaining jump ring " K " is also pressed more deadly by the screw thread of nut " 2 ", makes that finally nut " 2 " at all can't displacement.
Meanwhile, the anti-skidding wedge angle " P " on the retaining jump ring " K " also can be by nut " 2 " compressing and in the easier thread groove that rolls people's bolt " 1 ".Big more frequently shaking by force can not make retaining jump ring " K " slippage to some extent on the position of pressurized yet.
For this reason, the optimal design of the present invention on this problem is: retaining jump ring bottom section angle " b " should be slightly less than bolt thread groove angle " a ", and the hardness that retaining jump ring " K " is chosen material also should be higher than the hardness of bolt " 1 ".
If the present invention is the fastening position that is used between static and dismountable anything but engineering part:
So, on the structure shape of retaining jump ring " K ", hard and sharp anti-skidding wedge angle " P " can be set, at this moment the left view of Fig. 3 is similar to the sectional drawing of Fig. 4.In use, even if it is sliding that the contact position of the thread groove of bolt " 1 " and retaining jump ring " K " is non-ordinary light, but, because the screw thread of above-mentioned nut " 2 " is to " pressing " effect base reason of the minimum retaining jump ring " K " of the gradient, there is not this anti-skidding wedge angle " P " on the retaining jump ring " K ", also unimportant.Retaining jump ring bottom section angle this moment " b " should be slightly more than or equal to bolt thread groove angle " a ", and is when pressurized, favourable for the friction dynamics between the thread groove that strengthens retaining jump ring " K " and bolt " 1 ".
If, the present invention be used for that frequent generation is shaken by force and dismountable anything but engineering part between fastening position (example :) often by the take place frequently iron and steel bridge of judder of train:
So, retaining jump ring " K " is preferably set up hard and sharp anti-skidding wedge angle " P " in principle in design, and preferably more than one: if anti-skidding wedge angle " P " is many to forming sawtooth, it is convenient on the contrary to make like this, anti-skidding better effects if during frequent judder.At this moment, retaining jump ring 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 in the thread groove of bolt " 1 " into.This in the thread groove of preventing retaining jump ring " K " bolt " 1 " in the judder time delay that takes place frequently most effectively backward slippage be favourable.
In a word, adopt when of the present invention, generally, the main purpose that anti-skidding wedge angle " P " is set is " making provision against emergencies ", large-scale or giant-scale engineerings for some particularly are under the mal-condition that shakes by force that takes place frequently really, for " making provision against emergencies ", the a little stivers of polyvoltine (setting up anti-skidding wedge angle " P " on retaining jump ring " K ") come " buying an insurance ", also should be worth.
