Description
Technical field
The utility model is related to a kind of technical field of fastening, more specifically, it relates to a kind of flange face bolt.
Background technology
Bolt, machine components, the cylindrical threaded fastener of adapted nut.It is dimerous by head and screw rod
A kind of fastener need to coordinate with nut, for being fastenedly connected two parts for carrying through-hole.This type of attachment claims bolt to connect
It connects.
Currently, flange face bolt in the market, it includes bolt head and the body of rod that is connect with bolt head.Traditional
Bolt, in connection in use, needing to add gasket, but the case where sometimes will appear few gasket, occurs, and then influences connection,
And anti-loosening effect.
Utility model content
In view of the deficienciess of the prior art, the purpose of this utility model is to provide a kind of easy to use, structural strengths
High and highly practical bolt.
To achieve the above object, the utility model provides following technical solution：A kind of flange face bolt, including bolt head
Portion and the body of rod being connect with bolt head, connector between the bolt head and the body of rod, connector include and bolt head
The upper joint face of connection and the lower joint face being connect with the body of rod, upper joint face are set to the support of bolt head side
Body, the outer surface of supporter are in outer male structure, and lower joint face includes the inner concave and setting and indent for being set to body of rod side
The edge surface of face side, edge surface are equipped with several anti-skid bulges, and the ratio between the area of inner concave and the area of edge surface
Example is 2：1.
By using above-mentioned technical proposal, connector between bolt head and the body of rod, by being set to bolt head and bar
Connector between body, connector provide the effect of gasket, improve the practical function of bolt, and integrated effect, increase
The convenient effect for having added installation, further sets connector to include the upper joint face and and bar connecting with bolt head
The lower joint face of body connection, and it is set on upper joint face the supporter of bolt head side, by setting in outside
Surface is the supporter of outer male structure, is improved to the guarantee in the structural strength of bolt head, and the setting of outer male structure so that
Supporter remains outside tension, compares flat structure, the structural strength of itself is stronger, and further by lower connection
Face is set as including being set to the inner concave and setting and the edge surface of inner concave side of body of rod side, and inner concave is set
It sets, then improves the support strength when bolt head is by downward active force, and several by being equipped on edge surface
Anti-skid bulge increases antiskid effect, and the ratio between the area of inner concave and the area of edge surface is 2：1, using above-mentioned ratio
Example setting, further improves structural strength of the bolt in stress, improves practical function.
The utility model is further arranged to：The trapezoidal shape in section of the anti-skid bulge, and two adjacent anti-skid bulges it
Between formed fluted, the interface of groove is " V "-shaped.
By using above-mentioned technical proposal, the trapezoidal shape in section of anti-skid bulge, by the way that anti-skid bulge is set as trapezoidal
Structure improves the structural strength of anti-skid bulge, and is formed fluted between two adjacent anti-skid bulges, and the interface of groove is in
" V " shape shape, the groove of " V " shape shape structure, reduces the range of resonance, while ensuring anti-skidding, and have prevent loosen
Effect.
The utility model is further arranged to：Ratio between the height of the supporter and the height of connector is in 0.5-
Between 0.6.
By using above-mentioned technical proposal, ratio between the height of supporter and the height of connector 0.5-0.6 it
Between, it is arranged using the above structure, the support effect to the intensity of bolt head can be improved, it is ensured that effective stiffening effect,
If being less than above-mentioned ratio, best stiffening effect is not achieved, if being above above-mentioned ratio, increases processing cost, because
This aforementioned proportion is best effect structure.
Description of the drawings
Fig. 1 is a kind of structural schematic diagram of flange face bolt embodiment of the utility model.
Fig. 2 is a kind of present invention looks up structural representation of flange face bolt embodiment of the utility model.
Specific implementation mode
A kind of flange face bolt embodiment of the utility model is described further referring to figs. 1 to Fig. 2.
A kind of flange face bolt, including bolt head 1 and the body of rod 2 that is connect with bolt head 1, bolt head 1 and bar
Connector 3 between body 2, by the connector 3 being set between bolt head 1 and the body of rod 2, connector 3 provides the effect of gasket
Fruit improves the practical function of bolt, and integrated effect, the convenient effect of installation is increased, further by connector 3
It is set as including the upper joint face 30 connecting with bolt head 1 and the lower joint face 31 that connect with the body of rod 2, and in upper connection
Face 30 is set to the supporter 301 of 1 side of bolt head, by setting in the supporter that outer surface is outer male structure
301, it improves to the guarantee in the structural strength of bolt head 1, and the setting of outer male structure so that supporter 301 remains
Outside tension, compare flat structure, the structural strength of itself is stronger, and further set lower joint face 31 to include
It is set to the inner concave 310 and setting and the edge surface 311 of 310 side of inner concave of 2 side of the body of rod, and inner concave 310 is set
It sets, then improves the support strength when bolt head 1 is by downward active force, and by being equipped on edge surface 311
Several anti-skid bulges 32 increase antiskid effect, and the ratio between the area and the area of edge surface 311 of inner concave 310 is 2：
1, it is arranged using aforementioned proportion, further improves structural strength of the bolt in stress, improves practical function.
The utility model is further arranged to, the trapezoidal shape in section of anti-skid bulge 32, by the way that anti-skid bulge 32 to be arranged
For trapezium structure, the structural strength of anti-skid bulge 32 is improved, and fluted 320 are formed between two adjacent anti-skid bulges 32,
The interface of groove 320 is " V "-shaped, and the groove of " V " shape shape structure reduces the range of resonance, while ensuring anti-skidding, and
Has the effect for preventing loosening.
The utility model is further arranged to, and the ratio between the height and the height of connector 3 of supporter 301 is in 0.5-
Between 0.6, it is arranged using the above structure, the support effect of the intensity to bolt head 1 can be improved, it is ensured that is effective to reinforce
Best stiffening effect is not achieved if being less than above-mentioned ratio in effect, if being above above-mentioned ratio, increases and is processed into
This, therefore aforementioned proportion is best effect structure.
The above is only the preferred embodiment of the present invention, is not intended to limit the utility model, the skill of this field
Art personnel carry out common variations and alternatives within the scope of technical solutions of the utility model should be included in the guarantor of the utility model
