Description
Technical field
The present invention relates to mechanical fitting fields, and in particular to a kind of Anti-extrusion screw.
Background technology
Screw is a kind of common fastener, is widely used on machinery, electric appliance and building.General material for metal or
Plastic cement, cylinder, surface carves irregular ditch and is known as screw thread.
Screw generally comprises nut and breechblock, nut is above-mentioned be provided with instrument coincide for the groove twisted, breechblock
On be provided with screw thread, for the screw thread of threaded hole engage after fixing screws.The existing mode for increasing engagement force is manually to exist
Screw thread glue is smeared on screw, it is time-consuming and laborious.Therefore, the present invention provides a kind of high intensity, the screw for preventing abjection.
The content of the invention
The technical problems to be solved by the invention are that increase engagement force mode in the prior art operates laborious complexity
The technical issues of.A kind of new Anti-extrusion screw is provided, which, which has, does not have in addition smear screw thread glue, improves peace
The characteristics of filling efficiency.
In order to solve the above technical problems, the technical solution used is as follows：
A kind of Anti-extrusion screw, including nut and breechblock, breechblock is cylinder, and screw thread is provided on cylindrical sides,
Nut is fixedly connected with one end of breechblock, and concave hollow cavity is set in the breechblock；The concave hollow cavity is away from nut
One end is provided with film for concave hollow cavity；Film is provided outside through mechanism, through mechanism in stubborn screw to screw hole bottom
It is stressed to puncture film during portion；Liquid screw thread glue is filled in the concave hollow cavity.
The operation principle of the present invention：The present invention sets the cavity of a concave shape in the middle part of breechblock.Inside cavity fills spiral shell
Line glue sets in the plane of cavity film then after film a mechanism to be set to be used in stubborn screw to screw hole again for sealing
During bottom, film to be pierced through by pressure, screw thread glue is released out of cavity.So as to, full of screw thread glue, enhance at screw thread
The engagement force of screw and screw hole screw thread, at the same it is easy to operate, it need not additionally increase process.
In said program, for optimization, further, the concave hollow cavity includes the through hole being arranged in breechblock, leads to
One end that hole is contacted with nut is tightly connected.
Further, the supporting rack included through mechanism positioned at film outside, support are included in breechblock connection
Support column；Supporting rack and it is thin between be provided with sharp comer mechanism, for sharp comer for puncturing film, support frame as described above can in stress
It generates compared with film out movement.Just raw deformation can the time during support column stress.
Further, shrinkage pool is set with supporting rack junction on the breechblock, the depth and supporting rack of shrinkage pool are highly consistent.
In stress, in supporting rack retraction breechblock, sharp comer mechanism punctures film according to the relative motion of supporting rack and film.
Further, the sharp comer mechanism is thimble.
Further, the liquid screw thread glue is high intensity screw thread glue.
Concave hollow cavity in the present invention can be only arranged in breechblock not through can also run through breechblock, make
With screw cap closures one end, other end diaphragm seal.Mode can reduce difficulty when processing screw in this.
Beneficial effects of the present invention：
Screw thread glue by interior envelope screw thread glue, while reducing mounting screw complexity, is filled into screw thread knot by effect one
At conjunction, so as to increase engagement force；
Effect two, by the way that, through processing, breechblock forms concave hollow cavity with nut 1, can reduce difficult processing by breechblock
Degree；
Effect three by using high intensity screw thread glue, can further improve engagement force between screw thread.

Specific embodiment
In order to make the purpose , technical scheme and advantage of the present invention be clearer, with reference to embodiments, to the present invention
It is further elaborated.It should be appreciated that specific embodiment described herein is not used to limit only to explain the present invention
The fixed present invention.
Embodiment 1
The present embodiment provides a kind of Anti-extrusion screws, such as Fig. 1, and including nut 1 and breechblock 2, breechblock 2 is cylinder, in circle
Screw thread is provided on column side face, nut 1 is fixedly connected with one end of breechblock 2, and concave hollow cavity 3 is set in the breechblock 2；
The concave hollow cavity 3 is provided with film 4 for concave hollow cavity 3 away from 1 one end of nut；Film 4, which is provided outside, to be run through
Mechanism is stressed through mechanism when stubborn screw is to screw hole bottom to puncture film 4；It is filled in the concave hollow cavity 3
Liquid screw thread glue.
The present embodiment：The present embodiment sets the cavity of a concave shape at 2 middle part of breechblock.Inside cavity fills screw thread glue,
Film 4 is set then after film 4 mechanism to be set to be used in stubborn screw to screw hole bottom again for sealing in the plane of cavity
When, film 4 will be pierced through by pressure, screw thread glue is released out of cavity.So as to, full of screw thread glue, enhance spiral shell at screw thread
The engagement force of nail and screw hole screw thread, at the same it is easy to operate, it need not additionally increase process.
Specifically, described to include being located at the supporting rack 7 in 4 outside of film through mechanism, support is included in the connection of breechblock 2
Support column 5；Supporting rack 7 and it is thin between be provided with sharp comer mechanism 6, sharp comer is for puncturing film 4, and support frame as described above 7 is in stress
When can generate corresponding deformation.
In addition, such as Fig. 3, shrinkage pool 8, depth and the supporting rack 7 of shrinkage pool 8 can be set on breechblock 2 with 7 junction of supporting rack
It is highly consistent.In stress, support column 5 is retracted in breechblock 2, and sharp comer mechanism 6 is according to the relative motion of supporting rack 7 and film 4
Film 4 is punctured, releases liquid screw thread glue.
In detail, the sharp comer mechanism 6 is thimble.
In order to improve engagement force, it is preferable that the liquid screw thread glue is high intensity screw thread glue.Screw thread glue uses 5222 screw threads
The liquid screw thread glue such as glue.
Embodiment 2
