Abstract
The utility model provides a combined bolt connecting all objects; the outer side of the tail of a bolt shank (1) of a common bolt (4) is provided with a bolt bushing (2) matching with the common bolt (4); the outer side of the bolt bushing (2) is provided with more than two bolt bushing heaves (3) around the bolt bushing (2), so as to form grooves (12) which are also arranged around the bolt bushing (2) between all the bolt bushing heaves (3); one side of the head of the bolt bushing (10) close to the common bolt (4) is provided with an inward bolt bushing bending structure (8); the edge of each bolt bushing heave (3) is arranged with slope-shaped bolt bushing heave slope gradient (7). The technical proposal of the combined bolt can reduce stress concentration between the bolt and the connected objects, more reliably connect the objects, and reduce the processing prevision requirement for light holes (13) of the connected objects, thereby reducing the processing cost of the light holes (13) of the connected objects.
Description
Technical field
The utility model relates to the connection set between a kind of object, more particularly relates to the connecting bolt between a kind of object.
Background technique
Bolt mainly is to play the effect that connects two objects, at present, need all connect with plain bolt with bolted object major part, and what plain bolt was used all is standard thread, therefore uses more extensive.The effect that this plain bolt has only played and simply fixed, tightened, because plain bolt is that direct face contacts with being connected between the object, but during owing to usefulness plain bolt connected element, the head of plain bolt can produce very big stress with the surface of contact that is connected object and concentrate, cause the fatigue of plain bolt especially easily, thereby can reduce the life-span of the plain bolt of under bad working environment, working.
The model utility content
A kind of bolt of the utility model, its objective is: provide a kind of bolt that can reduce to concentrate with the stress that is connected between the object, and can connect object more reliably, reduce the requirement on machining accuracy of the unthreaded hole of object, thereby reduce the bolt of the processing cost that connects the object unthreaded hole.
A kind of assembling bolt, comprise plain bolt, bolt bush that matches with plain bolt of bolt shank tail arranged outside at described plain bolt, described bolt bush is sleeved on the plain bolt, the lining top of bolt bush contacts with the plain bolt end face of plain bolt, and described plain bolt and bolt bush are formed assembling bolt.
Go out bolt bush projection more than the twice in the arranged outside of described bolt bush, thereby between each bolt bush projection, form same along the bolt bush groove in one week along one week of bolt bush.
Set out inwardly outstanding bolt bush bending structure at described bolt bush head to close plain bolt one side.
Set out the bolt bush protruding part gradient of slope shape at the edge of described bolt bush projection.According to the technical solution of the utility model, can access following beneficial effect:
1, reduced plain bolt effectively and concentrated, made that connection is more reliable with the stress that is connected the object surface of contact;
2, owing to being not that bolt directly contacts with connected body, not high to the unthreaded hole processing request that connects object, reduced the processing cost that connects object.
3, because the end of lining is designed to have certain gradient, be easy to enter connecting body, be easy to assembling, when particularly connecting, more can demonstrate the benefit of this kind bolt for the object that drafting angle is arranged.
Description of drawings
Make briefly bright to each width of cloth accompanying drawing of this specification expressed content and the mark among the figure below:
Fig. 1 is the structural representation of a kind of assembling bolt of the utility model;
Fig. 2 is the sectional structure schematic representation of the utility model when being connected with object;
Fig. 3 is the sectional structure schematic representation of plain bolt of the present utility model;
Fig. 4 is the sectional structure schematic representation that is connected the object attachment hole of the present utility model;
Be labeled as among the figure: 1, bolt shank tail; 2, bolt bush; 3, bolt bush projection; 4, plain bolt; 5, be connected object; 6, lining top; 7, the bolt bush protruding part gradient; 8, bolt bush dogleg section; 9, plain bolt and be connected the object surface of contact; 10, bolt bush head; 11, plain bolt head; 12, groove; 13, be connected the object unthreaded hole.
Embodiment
Contrast accompanying drawing below, by description, the effect of the mutual alignment between the shape of embodiment of the present utility model such as related each member, structure, the each several part and annexation, each several part and working principle etc. are described in further detail embodiment.
As shown in Figure 1 and Figure 2, assembling bolt of the present utility model is combined by plain bolt 4 and bolt lining 2.
Bolt bush 2 that matches with plain bolt 4 of bolt shank tail 1 arranged outside at described plain bolt 4, described bolt bush 2 is sleeved on the plain bolt 4, the lining top 6 of bolt bush 2 contacts with the plain bolt end face 9 of plain bolt 4, and described plain bolt 4 is formed assembling bolt with bolt bush 2.
Go out bolt bush projection 3 more than the twice in the arranged outside of described bolt bush 2, thereby between each bolt bush projection 3, form same groove 12 along 2 one weeks of bolt bush along 2 one weeks of bolt bush.
Set out inwardly outstanding bolt bush bending structure 8 at described bolt bush head 10 to a side near plain bolt 4.
Set out the bolt bush protruding part gradient 7 of slope shape at the edge of described bolt bush projection 3.
When assembling bolt of the present utility model when being connected object 5 and being connected, plain bolt 4 be connected object surface of contact 9 and be not and be connected object 5 and directly contact, but it is middle across bolt bush top 6, the effect of pad has been played at bolt bush top 6, increased plain bolt 4 and be connected object surface of contact 9 and be connected area of contact between the object 5, reduced the pressure of unit area, reduced the stress of surface of contact effectively and concentrated, make plain bolt 4 be connected between the object 5 be connected more reliable.
Any object all has a certain amount of resiliently deformable, and the bolt bush projection 3 that is provided with on bolt bush 2 is partially submerged into when being connected object 5, makes bolt bush 2 with to be connected being connected of object 5 more firm.
The bolt bush protruding part gradient 7 that sets out slope shape at the edge of bolt bush projection 3 makes bolt bush 2 to enter easily and is connected object 5, particularly connect, more can demonstrate the superiority of assembling bolt of the present utility model for the object that drafting angle is arranged.
The setting of bolt bush 2 head bolt bush dogleg section 8, not only make the bolt bush 2 and the area of contact of plain bolt 4 become big, prevent the undue inclination of bolt bush 2 in being connected object 5 effectively, on the other hand, also reduced the rolling momentum of plain bolt 4 in bolt bush 2.
Since increased bolt bush 2, neither be very high to the requirement on machining accuracy that is connected object unthreaded hole 13 parts, thus reduced the processing cost that is connected object unthreaded hole 13.
Assembling bolt of the present utility model also can increase a bolt shank tail 1, thereby assembling bolt is made stud bolt, according to demand to adapt to the needs of compound connection again on plain bolt head 11.
In conjunction with the accompanying drawings the utility model has been carried out exemplary description above, but specific implementation of the present utility model is not subjected to the restriction of aforesaid way.As long as adopted the improvement of the various unsubstantialities that design of the present utility model and technological scheme carry out, or design of the present utility model and technological scheme are directly applied to other occasion, all within protection domain of the present utility model without improving.
