Fig. 2 is the sectional view after existing connection set assembling is finished;
Fig. 3 is the sectional view before the connection set assembling of the present utility model;
Fig. 4 is the sectional view in the connection set assembly process of the present utility model;
Fig. 5 is the sectional view after connection set assembling of the present utility model is finished.
Embodiment
Below in conjunction with embodiment the utility model is elaborated, wherein identical component are represented with identical reference character.Need to prove, describe below the word " preceding " that uses, " back ", " left side ", " right side ", " on " and D score refer to direction in the accompanying drawing, word " interior " and " outward " refer to respectively towards or away from the direction of specific features geometrical center.
Please in conjunction with consulting Fig. 3-5, connection set of the present utility model comprises a bolt 10, adjusting nut 14, a nut part 16 and a nylon washer 18.
Described bolt 10 comprises bolt shank 100, is arranged on the bolt head 104 of these bolt shank 100 1 ends and the chamfering that is arranged on bolt shank 100 the other ends, and also is provided with the outside thread (not shown) near described chamfering place.Preferably, adjacent bolt head 104 also is provided with bolting pad 102 on the described bolt shank 100.
The adjusting nut clamping part 142 that described adjusting nut 14 comprises adjusting nut body 144 and is positioned at adjusting nut body 144 1 ends, the outer surface of described adjusting nut body 144 are provided with the screw thread 140 that can cooperatively interact with described nut part 16.One cylindrical cavity is arranged in the adjusting nut 14, and the external diameter of the diameter of this cavity and bolt shank 100 adapts, so that bolt shank 100 can pass this cavity just.
The nut part fixing part 162 that described nut part 16 comprises nut part body 164 and is positioned at nut part body 144 1 ends.There are two cavitys the inside of described nut part 16, be equipped with screw thread on the inwall of two cavitys, it wherein on the inwall of right side cavity reverse thread 160, and the diameter of left side cavity is less than the diameter of right side cavity, the diameter of described left side cavity and the external diameter of bolt shank 100 adapt, and the diameter of described right side cavity and the external diameter of adjusting nut body 140 adapt.
There is a through hole at the center of described nylon washer 18, and this nylon washer 18 embeds the end of described adjusting nut body 140.
Introduce the assembly process of connection set of the present utility model below.
When using connection set of the present utility model, at first described nut part fixing part 162 is fixed on a side of first to be connected 5, the means of fixation of being mentioned above it should be understood by one skilled in the art that can but be not limited to modes such as welding, splicing.Then, the adjusting nut 14 that nylon washer 18 is housed is screwed in the described nut part 16 from first to be connected 5 opposite side left-handed (counterclockwise).Then described bolt 10 is passed second to be connected 6, enter the cylindrical cavity of adjusting nut 14, bolt 10 returns and extrude internal thread on nylon washer 18 under the driving of assembling moment of torsion.Owing to when nylon washer 18 inwalls are extruded internal thread, can produce resistance, can drive adjusting nut 14 by this resistance nylon washer 18 and produce dextrorotation (clockwise) moment of torsion that continues, this right-hand torque can drive adjusting nut 14 and screw out described nut part 16, and adjusting nut 14 just can move axially (see figure 4) along the direction that described nut part 16 screws out.
Along with the screw-in of bolt 10, adjusting nut 14 constantly screws out, and until the sidewall of adjusting nut clamping part 142 near second to be connected 6, consequent then resistance can stop further moving axially of adjusting nut 14.Like this, bolt 10 just can move on, and passes adjusting nut 14, arrives the internal thread on nut part 16 tops, up to bolting pad 102 and second to be connected 6 surperficial applying (see figure 5).So far, use connection set of the present utility model that first to be connected 5 and second to be connected 's 6 the process of being fastenedly connected is finished.In addition, because nylon washer 18 finally still is fixed on the helical thread portion of bolt 10, therefore can also play locking effect.
In sum, connection set of the present utility model can be regulated the gap of two different sizes between member by the effect of an axially movable adjusting nut, and need not additionally to apply materials such as friction enhancer, this connection set technology is simple, reliable and stable, with low cost.
