Abstract
A fixed suppository has a suppository body with certain length, a suppository head is arranged on one side of the suppository body with the suppository area bigger than the suppository body area, at least two elastic bodies are arranged in one side of the suppository head corresponding to the suppository body, a card fixed part consisting of a conoid card fixed part is arranged in the suppository body corresponding to another end of the suppository head, an external diameter where the card fixed body connects with the suppository body is bigger than the suppository body external diameter and a card groove is arranged in a conoid bottom of the card fixed body, which is characterized in that the elastic body extends outward showing a helical form, the suppository body is a square body, a cylinder is arranged in the suppository body between the card fixed body and the suppository head, connectors connecting with the suppository body are respectively arranged on four edges of the cylinder, adoption of the helical form and the elastic body with space staying outward and shrinking inward reach effects of good elasticity, secure rapture and application to objects with different thickness.
Description
[technical field]
The utility model relates to a kind of fixed bolt that is used for fixing two articles.
[background technique]
General traditional fixed bolt structure, it has the key of a suitable length, and this key one end is provided with a bolt head, and the area of this bolt head is greater than the area of this key, and this key is provided with a holding division in the other end of relative bolt head, wherein:
One bolt head, this bolt head is provided with at least two elastomers in the one side of corresponding key, and this elastomer is to curve inwardly and form and has the elasticity that outwards supports to arrive in;
One holding division, this holding division are made of a cone shape fixing body, and this fixes the external diameter of the external diameter of body and key connecting part greater than key, and forming has a draw-in groove between fixing body and the key and can be fastened on the object;
In use, outwards support to arrive in by this elastomer, firmly and not can be gapped when its elasticity that has makes two articles be fastened between bolt head, the holding division.
But the elasticity that this existing elastomer outwards supports to arrive in is relatively poor, and when making two articles be fastened between bolt head, the holding division, steadiness is not good, and this existing elastomer only is confined to fix the object of certain width, can't be used on the thicker object.
[summary of the invention]
Be to solve known fixed bolt poor flexibility, steadiness is not good and can not be used in technical problem on the thicker object, the utility model provide a kind of have elasticity, steadiness good and be applicable to fixed bolt on the different-thickness object.
The technical solution of the utility model is: a kind of fixed bolt, it has the key of a suitable length, this key one end is provided with a bolt head, the area of this bolt head is greater than the area of this key, this bolt head is on the one side of corresponding key, be provided with at least two elastomers, this key is provided with a holding division in the other end of relative bolt head, this holding division is made of a cone shape fixing body, this fixes the external diameter of the external diameter of body and key connecting part greater than key, and in the cone bottom shape Cheng Youyi draw-in groove that fixes body, it is characterized in that: this elastomer shape in the shape of a spiral that stretches out has the elasticity that outwards supports to arrive in thereby form, and springing stroke, see through the elasticity that this elastomer outwards supports to arrive in, make two articles be fastened in the bolt head, in the time of between the holding division, can firmly and not can be gapped.
This key is a square cylinder.
This key is provided with a cylindrical body fixing between body and this bolt head, and this cylindrical body edge is respectively equipped with one and the connecting body that joins of this key.
As seen, the utility model by adopt shape in the shape of a spiral and outwards be formed with support to arrive in, and the elastomer in the space of inwardly contracting, and form have more traditional fixed bolt better outwards support to arrive in elasticity, and springing stroke, make when fixing two articles, the elasticity of utilizing this elastomer outwards to support to arrive in, when making these objects be fastened in this fixed bolt, can firmly and not can be gapped, to reach the steadiness better than the conventional fixed bolt, and utilize these elastomeric preferable springing stroke, more can cooperate to fix the thicker object of thickness.
Further specify the utility model below in conjunction with drawings and Examples.
[description of drawings]
Fig. 1 is the utility model stereo appearance figure.
Fig. 2 is the utility model user mode figure.
[embodiment]
See also shown in Figure 1, the utility model structure mainly is provided with one and has the key 3 of suitable length (in the present embodiment, this key 3 is a flat column), these key 3 one ends are provided with a bolt head 5 bigger than key 3 areas, and the holding division 7 of relative these bolt head 5 the other ends, wherein, on the one side of these bolt head 5 corresponding keys 3, be provided with at least two outward extending elastomers 51, this elastomer 51 is shape and form and have elasticity and the springing stroke that outwards supports to arrive in the shape of a spiral, makes this elastomer 51 have the space of inwardly contracting; And this holding division 7 is to be made of a cone shape fixing body 71, this fixes the external diameter of the external diameter of body 71 and key 3 connecting parts greater than key 3, make this fixing body 71 have certain folding and unfolding, and at the bottom of the awl that fixes body 71 and be formed with a draw-in groove 75 between the key 3, this holding division 7 is fastened on the object; This key 3 is provided with a cylindrical body 73 with 5 on this bolt head fixing body 71, and these cylindrical body 73 edges are respectively equipped with a connecting body 74 that joins with this key 3, increase the stability of fixing whereby.
See also shown in Figure 2, by the enforcement illustration that is used in forming of the above member when fixing an electronic component 81 and a Heat sink 83, it is that this holding division 7 is fastened on the preformed hole of PC plate 85 of electronic component 81, and this bolt head 5 is fastened in the schematic representation on the preformed hole of Heat sink 83, and the elasticity that outwards supports to arrive in by this elastomer 51, make electronic component 81, Heat sink 83 is fastened in this bolt head 5, between the holding division 7, it firmly and not can be gapped, simultaneously, because this elastomer 51 has the space of inwardly contracting, and the utility model is fixed on the object of different-thickness.
Above-described only is a preferred embodiment of the present utility model, when not limiting the scope that the utility model is implemented with it; Anyly be familiar with equalization that its feature of being put down in writing in to technical solutions of the utility model of this operator makes change and modify in this field, all should belong within the scope that technical solutions of the utility model contain.
