Description
Technical field
The utility model is related to screw technical field, and in particular to a kind of fast lock screw.
Background technology
Screw is the physics and mathematical principle of the inclined-plane circular rotating and frictional force that utilize 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 are used；TV, electric product, musical instrument, furniture etc.
General screw；Large-scale screw, nut are then used as engineering, building, bridge；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 joint invention over the past thousands of years in people's production and living, from the point of view of application field, and it is the first big of the mankind
Invention.
Although but existing screw can meet the effect of connection securing objects, be required to screw being directed at screw thread
Hole, then turns screw until its head top pressure just realizes the purpose of locking on object by the long period.If being only
Simple connection is needed to use, then such screw for installing connected mode will cause the unnecessary set-up time to waste, and influence
To operating efficiency.
Utility model content
For above-mentioned deficiency, the purpose of this utility model is there is provided a kind of smart structural design, rationally, it is easy to quick
The fast lock screw of locking is installed.
To achieve the above object, technical scheme provided by the utility model is：
A kind of fast lock screw, it includes the body of rod, one end of the body of rod by order from outside to inside be arranged with the first card convex with
Second card convex, the first card convex and the second card convex are arranged at intervals to form screens groove, and the width of the screens groove is the width of the first card convex
2~3 times, the front end of first card convex is in being gradually reduced shape formation tapered portion, the radially enlarged shape of the other end of the body of rod
Into head, it is in criss-cross boss that the end face on the head, which is provided with cross section,.
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, its off-balancesheet face is electroplate with color zinc layers, then makees dehydrogenation 6h processing, effectively
Lift wearability and alkali resistant acid-resisting.
As a kind of improvement of the present utility model, the width of first card convex and the second card convex is equal.
The beneficial effects of the utility model are：Smart structural design of the present utility model, rationally, utilize the cone of the first card convex
Shape portion can stretch into the locking hole of object, and the locking hole is engaged the purpose for realizing locking with screens groove, and saving tradition also needs
The process to turn screw for a long time, it is time saving and energy saving, while also without thread mill drilling, saving cost；But also provided with horizontal stroke
Section is in criss-cross boss, directly can be turned with hand or engagement tool, convenient, flexible regulation meets different use need
Ask.
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, the fast lock screw of one kind that the present embodiment is provided, it includes the body of rod, and one end of the body of rod is pressed by outer
The first card convex 1 and the second card convex 2 are arranged with to interior order, the width of the card convex 2 of the first card convex 1 and second is equal, described
First card convex 1 and the second card convex 2 are arranged at intervals and form screens groove 3, the width of the screens groove 3 for the width of the first card convex 1 2~
3 times, the front end of first card convex 1 is in shape formation tapered portion 11 is gradually reduced, and the other end of the body of rod is radially enlarged to be formed
Head 4, it is in criss-cross boss 41 that the end face on the head 4, which is provided with cross section,.Preferably, being provided with multiple ring-types at the middle part of the body of rod
It is raised（Figure is not being regarded）, the height of projection of the annular projection is less than the second card convex 2.Provided with annular projection, can further increase with
The frictional force between object need to be locked, locking stability is good, is connected firmly.
Preferably, the body of rod and head 4 are integrated attachment structure, it is connected firmly, structural stability is good.
Preferably, the off-balancesheet face that the utility model locks screw soon is electroplate with color zinc layers, then makees dehydrogenation 6h processing, effectively carry
Rise wearability and alkali resistant acid-resisting.
When needing installation locking, first, which need to lock object, is first enclosed on the body of rod and between the card convex 1 of head 4 and first
Position, then recycles the tapered portion 11 of the first card convex 1 is quick to stretch into second and need to lock the locking hole of object, and make the locking hole
The purpose for realizing locking is engaged with screens groove 3, the process that tradition also needs to turn screw for a long time is saved, it is time saving and energy saving, together
When also without thread mill drilling, save cost.Additionally, due to being in criss-cross boss 41 provided with cross section, hand can be directly used
Or engagement tool is turned, the angle of convenient, flexible regulation object assembling meets different use demands.
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 reality
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
Constitute any limitation.As described in the utility model above-described embodiment, using other spiral shells obtained from same or similar structure
Silk is in the utility model protection domain.
