Abstract

The utility model discloses a rivet tightening type screw bolt, the huge wedge tightening force which is generated when taper pins are used to pass through from taper holes in the center of a screw bolt is combined with the tightening force of a nut and the screw bolt after the combined innovation of the dual advantages of a traditional screw bolt and a traditional rivet is started, and the rivet tightening type screw bolt not only has the advantages of the traditional screw bolt but also has the advantages of the traditional rivet. The rivet tightening type screw bolt also has the advantages of convenient operation, and high safety; furthermore, the utility model is fearless of vibration and oil and can not be loosened and rusted, the nut of the utility model can not be fallen off, and buckles of the utility model can not be loosened; meanwhile, the utility model has the characteristics of fast installation speed and fast demounting speed. Each of the rivet tightening type screw bolts are totally formed by combining two semicircular column bodies which are provided with screw caps, the middle part of the utility model is formed with the taper holes after the two semicircular column bodies are combined, the middle upper parts of the taper holes are processed with a wedge mouth, the taper pins are matched with the taper holes, and small screw bolts of each of the taper pins are totally matched with the small screw caps.

Description

The formula of riveting tightly bolt

Technical field

The utility model relates to a kind of bolt, is a kind of bolt of formula of can riveting tightly specifically.Hereinafter to be referred as bolt.

Background technique

Known various bolts all are columniform at present, owing to be subjected to the influence of many-sided factors such as material machining accuracy and fit tolerance, conventional bolt and nut often produce the strip button, become flexible, move back button, fall cap or the like bad phenomenon when being used, the particularly cooperation of the various bolts and nuts in the environment of machinery oil is arranged, it is quite general to see loosening phenomenon, disposable the fastening if existing machinery oil is almost had no idea when being used of screw bolt and nut in the environment of certain shaking force arranged again forever.So often bring beyond thought accident and disaster for various device, various vehicle, various aircraft.For example walking the time just can often be seen from the fall down screw bolt and nut of different size of vehicle on highway.The shortcoming that simultaneously conventional bolts and nuts also exist another kind to be difficult to overcome when cooperating---after bolts and nuts are fastened, owing to be subjected to the influence of factors such as humid climate and environment, the bolts and nuts rust is dead, the phenomenon of burning to death is quite general, this situation has been brought huge difficulty to maintenance of equipment, increase unlimited burden to service worker, the for example construction in a new building, the screw bolt and nut of the various clamps above the light scaffold, must all get screwing of a circle circle and unloading of a circle circle, both increased working strength of workers, wasted the countless time again, list calculates in the whole of China's scope, and annual light is twisted bolt, man-hour that nut consumed and expense just can't be calculated.

Summary of the invention

The purpose of this utility model be buckle in order to overcome the strip that present widely used bolt, nut often produce, become flexible, move back buckle, fall cap, rust dead, require great effort in burning to death and using, shortcoming such as time-consuming, this is practical to provide a kind of and rivets tightly and tighten a kind of formula bolt of riveting tightly that combines, because this formula bolt of riveting tightly has and tightens fast and when unclamping fast advantage, also have after tightening and no longer to produce loosening function, think that the update of this traditional standard piece product of bolt created condition.

The utility model technological scheme that is adopted of dealing with problems is: each formula bolt of riveting tightly all is to combine with having two semicircular cylinders that bolt emits, about the cone tank of two semicircle cylinders formed cone shape hole after merging, process a wedge shape mouth in the middle and upper part of cone shape hole, again taper pin is cooperated installation with cone shape hole.

The utility model has the advantages that, design rivets tightly the formula bolt except the whole advantages with conventional bolt like this, the advantage that also has traditional rivet simultaneously and had, that is to say the effect that such formula bolt of riveting tightly can fasten workpiece with nut and bolt, can utilize the wedging power of taper pin that nut and bolt are further riveted tightly again again.Utilize the method, such formula bolt of riveting tightly be used in any industry all have safety, reliably, loosening, do not fall cap, rust incessantly, the wet goods advantage is not buckled, is not afraid of to strip.The formula bolt of riveting tightly has like this changed the shortcoming that conventional bolt does not tightly live forever in the environment of machinery oil is arranged, overcome conventional bolt simultaneously again and in a single day become rusty extremely, burn the disease of being used to that firmly just can't lay down.Like this She Ji the formula bolt of riveting tightly not only have locking fast, lay down fast advantage, and opened up a broader application market equally in the war products application facet.

Among the figure 1, screw thread 2, nut 3, left side cone tank 4, wedge shape mouth 5, taper pin 6, chamfering 7, right side cone tank 8, cone shape hole 9, bolt 10, nuts 11, taper pin microcephaly bolt 12, nut 13, merge seam

The tool present embodiment

Said as can be known bolt (9) is that to utilize two first circular cylinders and nuts (10) structure be one from Fig. 1, Fig. 2, Fig. 3, Fig. 4.Said left side cone tank (3) merges the back with right side cone tank (7) and form a cone shape hole (8) on the center line of bolt (9), and said taper pin (5) inserts from cone shape hole (8).In order to guarantee that taper pin (8) can not become flexible and come off again from cone shape hole (8) after wedging, the angle of taper pin (5) is necessary consistent with the angle of cone shape hole (8).Also fastening with little nut (12) and taper pin microcephaly Luo bolt (11).The tapering of said taper pin (5) and cone shape hole (8) can be selected between the 10-30 degree.In order to guarantee that nut (2) can be sleeved on above the bolt (9) easily, fast, need be processed into the shape of chamfering (6) to the head portion of bolt (9).For nut (2) can be unloaded down above bolt (9) easily fast, the spy processes a wedge shape mouth (4) to the centre of two semicircular bolts (9) inboard, two sides, and this wedge shape mouth (4) must be presented the wide shape that spreads down.The effect of this wedge shape mouth (4) is, when needs are unloaded nut (2) down above bolt (9) when, at first must impact the little end surface of taper pin (5) with hand hammer, extract taper pin (5) out afterwards, again wedge shape mouth (4) is merged, at this moment the internal diameter external diameter automatic and bolt (9) that is sleeved on the nut (2) above the bolt (9) is separated from certain interval, just can directly unload down with rotation hardly.The epimere part of bolt at this time (9) just is equivalent to dwindle automatically diameter, so just created very advantageous conditions to unloading lower nut (2) fast.Because such bolt (9) is used with taper pin (5) and can utilizes widely at various machinery, ship, aircraft and above the various vehicle also is adapted at various military equipments, above the vehicle.Particularly be used in the quick assembling aspect of the bridge of boats, have more advantageous advantage.The screw thread (1) on the said formula bolt surface of riveting tightly is in full accord with the screw thread on the bolt surface of using traditionally.

The angle of wedge shape mouth (4) can be greater than 0 degree as can be known from Fig. 5, Fig. 6, Fig. 7, smaller or equal to 40 degree, said left side cone tank (3) and right side cone tank (7) separately can be seen clearly among Fig. 7 from Fig. 5, Fig. 6 with the state that merges, and it can also be seen that the shape in half hole of cone shape hole (8) from Fig. 7.Said taper pin (5) and cone shape hole (8) all are cone shape.Said merging seam (13) is divided equally in the centre of wedge shape mouth (4), can not take over or take back.
