Description
Technical field
The relevant a kind of fastening piece of the utility model is specifically about a kind of swivel nut member that combines with part for part.
Background technique
The component of domestic automobile model generally adopt foamed material or substitute materials for wood to make at present, and fixing between part and the part generally is that swivel nut and the fixing structure of DRIVE SCREWS are inlayed in employing at foam or above the Dai Mu.Existing screw bushing structure, shown in the right part of Fig. 2 and Fig. 3, swivel nut 6 is comprised of the swivel nut body 6a of cylindrical body and the one end lip part 6b that forms that extends radially outwardly, and the external wall of swivel nut is formed with thread protrusion (indicating).Part 1 and part 2 is relative by junction plane A, its corresponding relative position be drilled with through hole 1 ', 2 ' and be processed with counterbore 1 at the end face of each part ", 2 ".The swivel nut body 6a of swivel nut 6 is namely faced down from end face A is pressed into through hole 2 "; its lip part 6b is embedded in counterbore 2 " in, behind the inner hexagonal hole 3a ' by artificial employing inner hexagon spanner insertion spiral shell head 3a the screw part 3b of screw 3 is screwed in the endoporus (indicating) of swivel nut 6, so that part 1 and 2 is fitted by junction plane A again.Because the impact of the nature of material is added screw 3 by manually being screwed into, as long as screw 3 is tightened a bit a little, swivel nut will come off from foam or above the Dai Mu, thereby causes gap and the poor generation of face of assembling between the part.Therefore just need to improve so that the combination between part reaches fits tightly the structure of swivel nut and its installation.
Summary of the invention
The purpose of this utility model provides a kind of improved fastening swivel nut that combines with part for part on the model, make swivel nut deviate from foam or Dai Mu in the time of can avoiding screw on the swivel nut of foam or Dai Mu, firmly to tighten, thereby make the combination between part reach reliably closely connected.
For achieving the above object, the technological scheme that adopts of the utility model:
The utility model provides a kind of fastening swivel nut that combines with part for part on the model, the relative reverse side of the junction plane that described part combines is formed with counterbore, described fastening swivel nut is inserted by the described counterbore on the described reverse side, and comprise: the swivel nut body, be the cylindrical body that consists of by along the axially extended inner and outer wall of coaxial line, be formed with the shape of threads projection at described outer wall; Described inwall consists of the endoporus of swivel nut body, be characterized in, also comprise a taper round heavy stand integrally formed with described swivel nut body, be by described swivel nut body wherein an end from the outer wall of a distance of end face that leaves this end towards this end face to outer diameter gradually with increasing extension form.
Described distance is less than or equal to the degree of depth of described counterbore.
The conical surface of described taper ring and the angle of end face are 35 °~65 °.
Described angle is preferably 45 °.
The beneficial effects of the utility model are: fastening swivel nut of the present utility model is fixedly got on by the reverse side from part, because swivel nut one end has the heavy stand of a circle taper round, when locking nut more firmly, the pulling force of the heavy stand on the swivel nut is just tighter, can guarantee that operator in the situation of tightening the screw of exerting oneself, guarantee that swivel nut does not come off from foam or above the Dai Mu.The utility model designs simple and easy, easy for installation, simple to operate, difficult drop-off, can reach the needs of model design and checking.
Description of drawings
Fig. 1 is the structural representation that is used for the fastening swivel nut of combination between part that adopts an embodiment of the utility model;
Fig. 2 is a stereogram through dissecing, and shows to adopt of the present utility model fastening swivel nut shown in Figure 1 and adopt existing swivel nut with the comparative structure of two part combinations;
Fig. 3 is the sectional view of Fig. 2, shows in detail to adopt of the present utility model fastening swivel nut shown in Figure 1 and adopt existing swivel nut with the comparative structure of two part combinations.
Embodiment
For above-mentioned purpose of the present utility model, feature and advantage can be become apparent, below in conjunction with accompanying drawing embodiment of the present utility model is elaborated.At first need to prove, the utility model is not limited to following embodiment, those skilled in the art should understand the utility model from the spirit that following mode of execution embodies, and each technical term can be done the most wide in range understanding based on Spirit Essence of the present utility model.Same or analogous member uses the same reference numerals to represent among the figure.
Fig. 1 illustrates an embodiment of the utility model a kind of fastening swivel nut 4 that combines with part for part on the model.As shown in the figure, the part 1 of two requirement combinations is relative by junction plane A with 2, each part 1 and 2 described parts are processed with respectively through hole 1 ', 1 ", the relative reverse side of the junction plane that combines is processed with counterbore 1 ", 2 ", fastening swivel nut 4 is by the counterbore 2 on the reverse side B of part 2 " insert.Fastening swivel nut 4 comprises: swivel nut body 4a is by along the axially extended inwall 4a of coaxial line " and the cylindrical body that consists of of outer wall 4a ', be formed with shape of threads projection 4c, inwall 4a at outer wall 4a ' " consist of the endoporus (indicating) of swivel nut body 4a; And the heavy stand 4b with the integrally formed taper round of swivel nut body 4a, this heavy stand 4b be by the swivel nut body wherein an end for example for example be less than or equal to counterbore 2 from distance of end face C of leaving this end in illustrated lower end " outer wall of depth towards this end face C to outer diameter gradually with increasing extension form.The conical surface of this taper ring and the angle of end face are 35 °~65 °, for example are preferably 45 °.
In that part 1 is as follows by the operation of screw 3 combinations with 2: with the swivel nut body 4a of fastening swivel nut 4 of the present utility model from one of them part for example the reverse side B relative with junction plane A of part 2 be pressed into the through hole 2 ', and the heavy stand 4b of taper ring is contacted with counterbore bottom surface on this reverse side, the through hole 1 ' of screw 3 from part 1 stretched into the through hole 2 ' of part 2, insert with inner hexagon spanner among the inner hexagonal hole 3a ' of spiral shell head 3a in the endoporus with the fastening swivel nut 4 that screw screwed in the reverse side end that is installed on part 2, firmly tighten until counterbore 1 is close in the spiral shell head bottom surface of screw " the bottom surface so that part 1 and 2 is combined closely in junction plane A.
From binding operation process between the structure of above-mentioned fastening swivel nut and part as can be known: because fastening swivel nut 4 is provided with the heavy stand 4b of taper round, reverse installation by swivel nut 4, after in the endoporus that screw 3 is screwed in the fastening swivel nut 4 the parts 2 from the front of part 1, in screwing screw 3 more firmly, the pulling force of heavy stand 4b on the swivel nut 4 is just tighter, thread 3 even the staff exerts oneself, and can will not be set in foam or the swivel nut above the Dai Mu 4 brings out.
In sum, the utility model is given up traditional front swivel nut is installed, and from the reverse side of part swivel nut is fixedly got on, design simple and easy, simple to operate, easy for installation, difficult drop-off, thus reach the needs of model design and checking.
Should be understood that those skilled in the art can make various changes or modifications the utility model after having read above-mentioned instruction content of the present utility model, these equivalent form of values fall within the application's appended claims limited range equally.
