Description
Technical field
It the utility model is related to screw technical field, and in particular to a kind of spring jam nut.
Background technology
Screw is the physics and mathematical principle of the inclined-plane circular rotating and frictional force using object, is fastened by easy stages
The instrument of implements parts.Screw is the general saying of fastener, daily pet phrase.Screw is work indispensable in daily life
Industry necessity:The minimum screw that such as camera, glasses, clock and watch, electronics use;TV, electric product, musical instrument, furniture etc.
General screw;As for engineering, building, bridge then using large-scale screw, nut;Traffic tool, aircraft, electric car, automobile etc. are then
It is used in combination for big primary screw.Screw industrially bears vital task, as long as there is industry on the earth, then the function of screw is eternal
It is important.Screw is the joint invention in people's production and living over the past thousands of years, and from the point of view of application field, it is the first big of the mankind
Invention.
It is next easily because of vibrations on screw but although existing screw can meet the effect for connecting securing objects
And occur releasing phenomenon;Therefore, being arranged with spring on screw, effectively it can prevent screw from being released because of vibration.It is but existing
Spring structure is relatively simple, and the length that is screwed into of screw is determined with personal subjectivity entirely.If it is excessive to be screwed into length, cause spring mistake
Degree compression and can not resilience, do not have anti-loose purpose.If being screwed into, length is very few, because of the elastic force deficiency of spring, while
Anti-loose purpose is not had.Therefore, people are when mounted, typically a ruler is taken to measure mounted screw, so
The adjustment for being screwed into or being back-outed again afterwards, this not only makes troubles to operation, and operating efficiency, adds production cost.
Utility model content
For above-mentioned deficiency, the purpose of this utility model is, there is provided a kind of smart structural design, rationally, be not easy to release,
The spring jam nut being connected firmly.
To achieve the above object, technical scheme provided by the utility model is:A kind of spring jam nut, it includes bar
Body and head, the end face center on the head are provided with flat recess, the curved depression in center of the flat recess, the top surface on the head
Peripheral position is provided with chamfering, and one end of the body of rod is provided with assembling screw thread, and middle part radial protrusion forms screens step, and the other end is connected to
On head and outer peripheral face radially reduces and forms installation spring groove.
As a kind of improvement of the present utility model, the body of rod and head are integrated attachment structure, are connected firmly, and structure is steady
It is qualitative good.
As a kind of improvement of the present utility model, the surface of the installation spring groove is provided with a plurality of axle center side along the body of rod
To the raised line of extension.
As a kind of improvement of the present utility model, its outer surface is electroplate with color zinc layers, then makees dehydrogenation 6h processing, effectively carry
Rise wearability and alkali resistant acid-resisting.
The beneficial effects of the utility model are:Smart structural design of the present utility model, rationally, the centre bit of flat recess
Curved depression is put, the area coordinated with tool heads can be increased, be not easy to slide;Provided with installation spring groove, brought to spring installation
It is convenient;Length is screwed into provided with the formation standardization of screens step, avoids the occurrence of stubborn not in place or is excessively screwed into problem, effectively save
Traditional measurement process, it is time saving and energy saving, not only increase operating efficiency, also improve the stability of installation, coordinate it is close, be not easy because
Shake and occur releasing phenomenon, be connected firmly, and overall structure is simple, compact, relative inexpensiveness, it is easy to accomplish, it is easy to
It is widely applied.
Below in conjunction with the accompanying drawings with embodiment, the utility model is further illustrated.
Brief description of the drawings
Fig. 1 is main structure diagram of the present utility model.
Fig. 2 is side structure schematic view of the present utility model.
Embodiment
Referring to Fig. 1 and Fig. 2, a kind of spring jam nut of the present embodiment offer, it includes the body of rod 1 and head 2, the head
2 end face center is provided with flat recess 21, the curved depression in center of the flat recess 21, provided with arc-shaped recess, can increase with
The area that tool heads coordinate, is not easy to slide;The top surface peripheral position on the head 2 is provided with chamfering 22, avoids wedge angle from hurting sb.'s feelings phenomenon;Bar
One end of body 1 is provided with assembling screw thread 11, and middle part radial protrusion forms screens step 12, and the other end is connected on head 2 and periphery
Face diameter installs spring groove 13 to formation is reduced.
Preferably, the body of rod 1 and head 2 are integrated attachment structure, it is connected firmly, structural stability is good.
Extend preferably, a plurality of axis direction along the body of rod 1 can also be provided with the surface of the installation spring groove 13
Raised line(Do not regarded in figure), on the basis of lift structure intensity, the contact area of installation spring groove 13 and spring is also reduced, is subtracted
Few frictional force, avoids spring stuck phenomenon, also beneficial to the expanding-contracting action of spring.
To increase the service life, the outer surface of the utility model spring jam nut is electroplate with color zinc layers, then makees dehydrogenation
6h processing, effectively lift wearability and alkali resistant acid-resisting.
In use, the utility model spring jam nut is directly put into spring and is screwed into the screw of object, when stubborn
During to required depth, the screens step 12 is accordingly pressed on the surface of object, and form standardization is screwed into length, avoids out
Now twist not in place or be excessively screwed into problem, effectively save traditional measurement process, it is time saving and energy saving, operating efficiency is not only increased,
The stability of installation is improved, is coordinated closely, is not easy to occur releasing phenomenon because of vibrations, is connected firmly.
The announcement and teaching of book according to the above description, the utility model those skilled in the art can also be to above-mentioned realities
The mode of applying is changed and changed.Therefore, the utility model is not limited to embodiment disclosed and described above, right
Some modifications and changes of the present utility model should also be as falling into scope of the claims of the present utility model.In addition, to the greatest extent
Some specific terms have been used in pipe this specification, but these terms are merely for convenience of description, not to the utility model
Form any restrictions.As described in the utility model above-described embodiment, using other spiral shells obtained from same or similar structure
Silk is in scope of protection of the utility model.
