Description
Technical field
Technical field of fastening is the utility model is related to, more particularly to a kind of plug screw with auto-lock function.
Background technology
Existing plug screw only has a parts, depends merely on the threaded connection of plug screw and equipment in use
To ensure the fastening effect to equipment, therefore this fastening means be easy to cause the pine of plug screw when running into machine shake
It is dynamic, and then cause plug screw abrasion to come off, equipment mechanism failure, brings unnecessary loss, it is therefore desirable to optimize plug spiral shell
The structure of silk.
The content of the invention
Technical problem to be solved in the utility model is to provide a kind of plug screw with auto-lock function, has dismounting side
Just, locking self-locking effect is good, the features such as may be reused.
Technical solution is used by the utility model solves its technical problem：A kind of plug spiral shell with auto-lock function is provided
Silk, including self-locking plug and plug extension bar, the self-locking plug are provided with regular hexagon groove and circumference including one end and process
Threaded first cylindrical plug body, the described first cylindrical plug body other end are provided with truncated cone-shaped boss and round platform
The center of shape boss and the center of circle of the first cylindrical plug body be not coaxial, and the plug extension bar is provided with truncated cone-shaped including one end
The the second cylinder plug body and round platform connected in star of groove are combined together with truncated cone-shaped boss, the described second cylindrical plug
The other end of body is provided with the extension bar being coaxial therewith, and is threaded on the circumference of the described second cylindrical plug body,
The truncated cone-shaped bottom portion of groove is provided with regular hexagon groove.
Supplemented as one kind to technical solution described in the utility model, the truncated cone-shaped boss and the first cylinder are stifled
The eccentricity of head body is 0.5mm, effective to lock plug extension bar.
Supplemented as one kind to technical solution described in the utility model, the truncated cone-shaped boss and round platform connected in star
Coning angle is 15 °.
Beneficial effect：A kind of plug screw with auto-lock function is the utility model is related to, by the way that boss extension bar is tightened
One end connects a self-locking plug structure with eccentric round platform shape boss afterwards, due to the company of truncated cone-shaped boss and plug extension bar
It is different to connect place's concentricity, when further tightening self-locking plug, the radial load of generation can compress plug extension bar, and then prevent
The loosening of plug extension bar, the utility model have convenient disassembly, and locking self-locking effect is good, the features such as may be reused.

Fig. 4 is the left view of the utility model plug extension bar.
Reference numeral：1st, regular hexagon groove, 2, self-locking plug, 3, truncated cone-shaped boss, 4, round platform connected in star, the 5, second circle
Cylindricality plug body, the 6, extension bar, 7, first cylindrical plug body, 8, plug extension bar.
Embodiment
With reference to specific embodiment, the utility model is expanded on further.It is to be understood that these embodiments are merely to illustrate this
Utility model rather than limitation the scope of the utility model.In addition, it should also be understood that, reading the content of the utility model instruction
Afterwards, those skilled in the art can make various changes or modifications the utility model, and such equivalent forms equally fall within this Shen
Please the appended claims limited range.
The embodiment of the utility model is related to a kind of plug screw with auto-lock function, as shown in Figs 1-4, including self-locking
Plug 2 and plug extension bar 8, the self-locking plug 2 are provided with what is be threaded on regular hexagon groove 1 and circumference including one end
First cylindrical plug body 7, described first cylindrical 7 other end of plug body is provided with truncated cone-shaped boss 3 and truncated cone-shaped is convex
The center of platform 3 and the center of circle of the first cylindrical plug body 7 be not coaxial, and the plug extension bar 8 is provided with truncated cone-shaped including one end
The the second cylinder plug body 5 and round platform connected in star 4 of groove 4 are combined together with truncated cone-shaped boss 3, second cylinder
The other end of plug body 5 is provided with the extension bar 6 being coaxial therewith, and is processed on the circumference of the described second cylindrical plug body 5
There is screw thread, 4 bottom of round platform connected in star is provided with regular hexagon groove 1.
The eccentricity of the cylindrical plug body 7 of truncated cone-shaped boss 3 and first is 0.5mm,
The coning angle of the truncated cone-shaped boss 3 and round platform connected in star 1 is 15 °.
Embodiment
When use, by plug extension bar 8 installed in the position that equipment needs to fasten, with allen driver and positive six
Side connected in star 1 tightens plug extension bar 8 with turn screwdriver is merged, and self-locking plug 2 further is connected to plug extension bar 8
One end, tighten self-locking plug 2, then truncated cone-shaped boss 3 is adapted to round platform connected in star 4, due to truncated cone-shaped boss 3 and truncated cone-shaped
4 concentricity of groove is different, and radial load can be produced during self-locking plug 2 is tightened and compresses the second cylindrical plug body 5, real
The effect now locked to plug extension bar 8.
