It the utility model is related to screw technique field, especially a kind of soket head cap screw, including nut, one end of the nut is provided with screw rod, the screw rod is arranged concentrically with nut, the surface of the screw rod is provided with screw thread, end surface of the nut away from screw rod is provided with the first hexagonal cavity, the bottom of first hexagonal cavity is provided with cushion chamber, the bottom of the cushion chamber is provided with the second hexagonal cavity, first hexagonal cavity, cushion chamber, second hexagonal cavity connects, and three is arranged concentrically with nut, circumference of the inside of the nut along the first hexagonal cavity is uniformly provided with multiple bosses.The second hexagonal cavity that the utility model is set can play good safety effect, when the first hexagonal cavity damages, take out screw by the second hexagonal cavity, avoid the situation that screw can not take out, simple in construction, easy to use；The reinforcement block structure of setting improves the intensity of the first hexagonal cavity, alleviates the abrasion of the first hexagonal cavity, improves the service life of screw.
Description
Technical field
It the utility model is related to screw technique field, more particularly to a kind of soket head cap screw.
Background technology
Soket head cap screw is widely used, and is mainly used in connection between mechanical component, fastening etc., in use, interior hexagonal spiral shell
The nut of nail with whole rivet nut enter machinery inside, mounted and dismounted by distinctive instrument, screw it is interior
Hexagonal, which is used for multiple times, to be easily damaged, and when the interior hexagonal damage of screw, screw is not easily taken out, and use is made a big impact.
Utility model content
The purpose of this utility model is to be not easy to take to solve to exist in the prior art screw after the damage of the interior hexagonal of screw
The shortcomings that going out, and the kind soket head cap screw proposed.
To achieve these goals, the utility model employs following technical scheme：
A kind of soket head cap screw, including nut are designed, one end of the nut is provided with screw rod, and the screw rod and nut are concentric
Setting, the surface of the screw rod is provided with screw thread, and end surface of the nut away from screw rod is provided with the first hexagonal cavity, and described first
The bottom of hexagonal cavity is provided with cushion chamber, and the bottom of the cushion chamber is provided with the second hexagonal cavity, first hexagonal cavity, cushion chamber,
Second hexagonal cavity is connected, and three is arranged concentrically with nut, and the inside of the nut is uniformly set along the circumference of the first hexagonal cavity
There are multiple bosses, the one end of the screw rod away from nut is provided with screw head.
Preferably, the side surface of the nut is uniformly provided with multiple stripeds along its circumference.
Preferably, the section of the boss is trapezoidal.
Preferably, the surface of the screw head is arc.
The utility model proposes a kind of soket head cap screw, beneficial effect is：The second hexagonal cavity set can play
Good safety effect, when the first hexagonal cavity damages, screw is taken out by the second hexagonal cavity, avoiding screw can not take out
Situation, it is simple in construction, it is easy to use；The reinforcement block structure of setting improves the intensity of the first hexagonal cavity, alleviates the one or six
The abrasion of angle chamber, improve the service life of screw.
Brief description of the drawings
Fig. 1 be the utility model proposes a kind of soket head cap screw structural representation；
Fig. 2 be the utility model proposes a kind of soket head cap screw nut structure sectional view.
In figure：Nut 1, screw rod 2, screw thread 3, the first hexagonal cavity 4, cushion chamber 5, the second hexagonal cavity 6, boss 7, screw head
8。
Embodiment
Below in conjunction with the accompanying drawing in the utility model embodiment, the technical scheme in the embodiment of the utility model is carried out
Clearly and completely describing, it is clear that described embodiment is only the utility model part of the embodiment, rather than whole
Embodiment.
Reference picture 1-2, a kind of soket head cap screw, including nut 1, the side surface of nut 1 are uniformly provided with multiple along its circumference
Striped, the frictional force between screw and installation machinery can be improved, makes screw difficult for drop-off, one end of nut 1 is provided with screw rod 2,
Screw rod 2 is arranged concentrically with nut 1, and the surface of screw rod 2 is provided with screw thread 3, and end surface of the nut 1 away from screw rod 2 is provided with the one or six
Angle chamber 4, the first hexagonal cavity 4 are used to mount and dismount screw, and the bottom of the first hexagonal cavity 4 is provided with cushion chamber 5, the bottom of cushion chamber 5
Portion is provided with the second hexagonal cavity 6, and the first hexagonal cavity 4, cushion chamber 5, the second hexagonal cavity 6 connect, and three with nut 1 is concentric sets
Put, when the first hexagonal cavity 4 damages, screw is dismantled by the second hexagonal cavity 6.
Circumference of the inside of nut 1 along the first hexagonal cavity 4 is uniformly provided with multiple bosses 7, and boss 7 is used to improve first
The intensity of hexagonal cavity 4, the abrasion of the first hexagonal cavity 4 is reduced, the section of boss 7 is trapezoidal, makes its connecing with the first hexagonal cavity 4
Contacting surface product is bigger, and the one end of screw rod 2 away from nut 1 is provided with screw head 8, and beneficial to installation, the surface of screw head 8 is arc, operation
Phenomena such as person is not in scuffing, use are safer.
Operation principle：Screw head 8 is put into mounting hole, hex tool is put into the first hexagonal cavity 4, turns screw,
Installation is completed, reverse operating during dismounting；When the first hexagonal cavity 4 damages, select suitable hex tool and be put into
In two hexagonal cavities 6, screw is backed out.
It is described above, the only preferable embodiment of the utility model, but the scope of protection of the utility model is not
This is confined to, any one skilled in the art is in the technical scope that the utility model discloses, according to this practicality
New technical scheme and its utility model design are subject to equivalent substitution or change, should all cover in protection model of the present utility model
Within enclosing.
