Description
Technical field
The utility model is related to a kind of lock-screws, belong to screw interconnection technique field.
Background technology
At present in the prior art, screw thread connection it is most widely used, but some specific conditions requirement under, it is necessary to
There is a kind of screw not only to couple parts, and after being accurately positioned the screw belt locking function is made closely to be connected with parts again
It is integrated, however existing screw in the art is not met by this needs used.
Utility model content
The purpose of this utility model is to provide a kind of simple in structure, easy to use and energy reliable location and locks connection
Lock-screw, with overcome the deficiencies in the prior art.
What the technical solution of the utility model was realized in：
A kind of lock-screw of the utility model, the shape including the lock-screw are the screw of cylindrical shape, are being locked
The front end of screw is equipped with small column boss, and the outside diameter of small column boss is straight less than the externally threaded thread root of lock-screw
Footpath；Groove, the most narrow spacing of the slot bottom of groove to the externally threaded thread root of lock-screw are equipped in the rear end portion of lock-screw
From for 0.8~1.5 millimeter.
Above-mentioned groove is linear type groove or is cross groove.
By adopting the above-described technical solution, the utility model has following technology advantageous effect：The utility model exists
A small column boss is provided with before lock-screw, the end face of this small column boss has higher flatness, at work
It can be accurately positioned, the most narrow spacing of the slot bottom of the groove of lock-screw rear end to the externally threaded thread root of lock-screw
From control in the range of 0.8 millimeter~1.5 millimeters, it so can not only effectively enable groove by spreading, and also assure
The intensity of lock-screw.So the utility model is compared with prior art, the utility model not only has simple in structure, user
Just the advantages of, but also have the advantages that energy reliable location and effectively locking connect.The utility model is particularly suitable for needing
When coupling parts, the occasion for making screw belt locking function after screw accurate positionin and being closely connected as one with parts makes
With.
Description of the drawings
Fig. 1 is the structure diagram of the utility model；
Fig. 2 is the right view of Fig. 1；
Fig. 3 is that the connection structure when lock-screw of the utility model is connected with parts and passed through after rushing the instrument spreading that rises is shown
It is intended to.
Mark in attached drawing for：1- lock-screws, 2- small column boss, 3- grooves, 4- conical surface blocks, 5- rush the instrument that rises, 6-
Parts, 7- lug bosses, the outside diameter of d- small column boss, D- thread root diameters, the slot bottom of L- grooves to lock-screw
The distance between the minimum range of externally threaded thread root, the maximum gauge on the conical surface of Q- conical surface blocks, slot bottom of H- grooves.
Specific embodiment
The utility model is described in further detail with reference to the accompanying drawings and examples：
The embodiment of the utility model：
The utility model is according to constructed by a kind of locking method of following lock-screws and for this method, is such as schemed
Shown in 1-3, lock-screw 1 is fabricated to the screw of cylindrical shape by this method first when making lock-screw 1, and in the circle
The front end of the lock-screw 1 of post shapes makes a small column boss 2, and the outside diameter d of the small column boss 2 is made to be less than locking
The externally threaded thread root diameter D of screw 1；Groove 3 is produced in the rear end portion of lock-screw 1 simultaneously, makes the slot bottom of groove 3
Minimum range L to the externally threaded thread root of lock-screw 1 is 0.8 millimeter~1.5 millimeters；Then lock-screw 1 is twisted
In the parts 6 for entering threaded hole connected to it and with blind hole, support the bottom plane of the small column boss 2 of lock-screw 1
It leans against on the bottom hole face of the threaded hole of parts 6, so as to be positioned to lock-screw 1, when lock-screw 1 and parts 6 are connected to
Behind position, instrument 5 is risen by 3 spreading of groove using punching, make the lock-screw 1 corresponding to the groove after spreading 3 external screw thread generate it is convex
Portion 7 is played, which imbeds in parts 6, and lock-screw 1 can so be made to generate locking function, prevent lock-screw 1 from rotating
Be dragged out.The used punching instrument 5 that rises can directly be risen instrument using electronic punching of the prior art, in order to reduce cost and make
With more convenient, also the instrument that rises can be rushed by rush that the instrument 5 that rise is made as straight rod-shaped of the front end with conical surface block 4（As shown in Figure 3）,
The conical surface block 4 is enable to inject in groove 3, and make maximum gauge Q on the conical surface of the conical surface block 4 be more than groove 3 slot bottom it
Between distance H；Jiang Chong rise the conical surface block 4 of instrument 5 inject in groove 3 when, risen impacting punching by way of 5 tail end of instrument
Make conical surface block 4 by 3 spreading of groove.
It is formed according to the above method and is used for a kind of lock-screw of the utility model of the above method, as shown in Figs. 1-3,
Shape including the lock-screw 1 is the screw of cylindrical shape, and a small column boss 2 is produced in the front end of lock-screw 1,
The outside diameter d of small column boss 2 is made to be less than the externally threaded thread root diameter D of lock-screw 1；After lock-screw 1
End makes a groove 3, groove 3 can be fabricated to linear type groove or for cross groove, making is, by the slot of groove 3
Bottom to the externally threaded thread root of lock-screw 1 minimum range L controls in 0.8 millimeter~1.5 millimeters of scope.
