Abstract
The utility model provides a kind of Combined screw, including screw and the screw terminal cap covered on the screw head, the die that the screw terminal cap bottom includes being located in the middle of the screw terminal cap bottom and matched with the screw head dummy, and the annular outer cover being connected with counter sink inner wall sealing, the screw head dummy is interference fitted with the die, the die and shell connection integrated with the screw terminal cap bottom, the outer shell outer wall includes at least two semicolumns for being evenly distributed on the outer shell outer wall, semicolumn connection integrated with the outer shell outer wall.The utility model is simple in construction, and assembly and disassembly are easy, can protect screw well while preventing that screw from releasing.
Description
Technical field
The utility model is related to technical field of fastening, more particularly to a kind of Combined screw.
Background technology
Screw is used in various fields, for securing two components.In machinery equipment field, some equipment or zero
Part is operated in rugged environment, easily allows screw burn into reduce its life-span or even destroy its function.In addition in vibration frequently
Under environment, screw easily loosens, and conventional method is exactly gluing, but is difficult once being torn open after gelling admittedly.
Utility model content
The utility model purpose is a kind of Combined screw for proposing a kind of corrosion preventive and strength and preventing screw from releasing.
It is achieved through the following technical solutions above-mentioned purpose：
The utility model provides a kind of Combined screw, including screw and the screw head cap that covers on the screw head
Part, the mould that the screw terminal cap bottom includes being located in the middle of the screw terminal cap bottom and matched with the screw head dummy
Benevolence, and the annular outer cover being connected with counter sink inner wall sealing, the screw head dummy are interference fitted with the die, the die
With shell connection integrated with the screw terminal cap bottom, the outer shell outer wall is evenly distributed on including at least two
The semicolumn of the outer shell outer wall, semicolumn connection integrated with the outer shell outer wall.
By using above-mentioned technical proposal, the screwed hole of counter sink is provided with, first by screw tightening into screwed hole.Then make
Counter sink outer wall is provided with the groove matched with screw terminal cap shell semicolumn, then screw terminal cap is pressed into counter sink, screw
The die of head cap part and screw head dummy gap with merge and screw head dummy formed it is quiet couple, the outer wall and counter sink of screw terminal cap
Inwall is interference fitted, and the groove of the semicolumn of screw terminal cap outer wall and counter sink coordinates, this make screw by screw terminal cap with
External world's isolation.Make screw terminal simultaneously and screw terminal cap be quiet couples, screw terminal cap and with counter sink is quiet couples, so as to reach anti-
The effect that only screw is released.
It is preferred that, the screw terminal cap top surface is smooth surface.
By using above-mentioned technical proposal, in screw terminal cap press-in counter sink, when removed, by vacuum by screw terminal
The smooth top surface of cap is sucked, and is smoothly taken out.
The beneficial effects of the utility model are：By above structure, screw is set to be isolated from the outside by screw terminal cap.Together
When screw terminal cap outer wall semicolumn prevent that screw terminal cap from rotating, and the die of screw terminal cap is matched somebody with somebody with the screw head dummy
Close, so as to reach the effect for preventing screw from releasing.The utility model is simple in construction, and assembly and disassembly are easy, can protect screw same well
When prevent that screw from releasing.
Brief description of the drawings
Fig. 1 is the utility model overall structure semi-cutaway；
Fig. 2 is the utility model screw terminal cap profile.
Embodiment
The utility model is described in further detail with embodiment below in conjunction with accompanying drawing：
Shown in Fig. 1 to Fig. 2, a kind of Combined screw, including screw 1 and the screw terminal that covers on the head of screw 1
Cap 2, what the bottom of screw terminal cap 2 included being located in the middle of the screw terminal cap bottom and matched with the screw head dummy
Die 21, and the annular outer cover 22 being connected with counter sink inner wall sealing, the head dummy of screw 1 are matched somebody with somebody with the interference of die 21
Close, the die 21 and the shell 22 connection integrated with the bottom of screw terminal cap 1, the outer wall of shell 22 are included extremely
Rare two be evenly distributed on the outer shell outer wall semicolumn 221, the semicolumn 221 is integrated with the outer shell outer wall 22
Connection.
By using above-mentioned technical proposal, the screwed hole of counter sink is provided with, first by screw tightening into screwed hole.Then make
Counter sink outer wall is provided with the groove matched with screw terminal cap shell semicolumn, then screw terminal cap is pressed into counter sink, screw
The die of head cap part and screw head dummy gap with merge and screw head dummy formed it is quiet couple, the outer wall and counter sink of screw terminal cap
Inwall is interference fitted, and the groove of the semicolumn of screw terminal cap outer wall and counter sink coordinates, this make screw by screw terminal cap with
External world's isolation.Make screw terminal simultaneously and screw terminal cap be quiet couples, screw terminal cap and with counter sink is quiet couples, so as to reach anti-
The effect that only screw is released.
It is preferred that, the top surface of screw terminal cap 2 is smooth surface.
By using above-mentioned technical proposal, in screw terminal cap press-in counter sink, when removed, by vacuum by screw terminal
The smooth top surface of cap is sucked, and is smoothly taken out.
The above is not imposed any restrictions to this new technical scope, it is all according to the utility model technical spirit to
On embodiment any modification, equivalent variations and the modification made, in the range of still falling within this new technical scheme.
