Abstract
The utility model relates to a locating pin capable of axially and circularly rotating positioning which comprises a pin body (1), a spring (2), and a marble (3); the pin body (1) is divided into a fixed connection segment (5) and an axially positioning segment (4); the end surface of the axially positioning segment (4) of the pin body (1) is provided with a sleeve hole (6). The utility model can cause two axes to sleeve and match so as to obtain axially positioning as well as the positioning pin which is rotationally and movably positioned on a circumference simultaneously; the utility model has the advantages of simple structure, stability and reliability, decreasing materials, and compact structure; the area of two axes sleeved is effectively reduced.
Description
Technical field
The utility model belongs to mechanical connection locating pin structure technical field.
Background technique
Existing mechanical connects locating pin structure, especially diaxon is nested and connects when cooperating, the structure of locating stud normally adopts the cylindrical body of an entity as pin, plays the axially locating effect in the annular cotter way of being opened on the axle in being inserted into along the pin-and-hole of being opened on the outer cylinder.But this locating stud often can only play the positioning action that the restriction diaxon is nested and moves along shaft axis, can not play the activity orientation effect of rotation along the circumferential direction simultaneously.Therefore, also need on the fitting surface that diaxon is nested, to offer again the movable locating device that is used for the circumference rotation on the structural design, making structure seem complicated, the manufacturing difficulty of processing is big, also increases the fitting surface that diaxon is nested, thereby increases physical dimension, increase material consumption, strengthen cost of production.
Summary of the invention
The purpose of this utility model provide in order to overcome above-mentioned the deficiencies in the prior art just a kind of diaxon was nested cooperate obtain axially locating, also obtain the locating stud of activity rotation positioning on the circumference simultaneously.
The purpose of this utility model is achieved by the following technical solution.
Can axially reach the locating stud of circumference rotation positioning, it includes shank, spring and a pellet shot from a slingshot; On shank, be divided into fixedly connected section and axially locating section, offer a trepanning at shank axially locating section end face.
Spring of the present utility model and pellet shot from a slingshot place in the trepanning, have attacked screw thread on fixedly connected section of shank; Trepanning is monolateral hole or through hole.
The activity orientation function that axial displacement that the utility model connects owing to the restriction diaxon with shank is nested and circumference rotate is integrated in one, and has simplified linkage structure, can make two links realize above-mentioned two functions in less surface of contact cooperation.The utility model is simple in structure, and is reliable and stable, can reduce the diaxon area that is nested effectively, reduces and use material, makes structure become exquisite suitable.
Further set forth content of the present utility model below in conjunction with Figure of description.
Description of drawings
Fig. 1 is the utility model structural representation.
Fig. 2 is that the utility model is applied in the structural representation on the water valve.
Embodiment
The utility model can be used for all kinds of axle of mechanical field with spool the long splice member that is nested on, for example being nested between valve body and the water outlet is connected in the water valve, for making water outlet prevent that again water outlet and valve body from moving axially, adopt the utility model very suitable along rotating on the valve body circumference.During concrete the application, water outlet or valve body are offered a circular groove 9 on the cooperation section as inner cylinder connecting tube 7, and on groove, offer setting circle arc fluting 10 again, on outer cylinder connecting tube 8, be drilled with threaded pin-and-hole 11 then, the utility model is screwed in the hole, its axially locating section 4 embeds in the circular groove 9 and plays the effect that restrictive axial moves, and pellet shot from a slingshot 3 is going to the arc groove of being opened on the circular groove 9 10 and is springing in the groove when shank 1, play mutual effect to the circumference rotation positioning, continue on circumference, to rotate if need, then twist the outer cylinder connecting tube, under the effect of torsion, pellet shot from a slingshot 3 pressuring springs 2 make the pellet shot from a slingshot retraction, can go to any angular position on circular groove 9 circumference.
The utility model material is selected metal usually for use, and the profile diameter of shank 1 is decided on connection request, is processed with screw thread fixedly connected section 5 of shank 1, cooperates in order to be threaded with pin-and-hole.Axially locating section 4 diameters of shank 1 are less than fixedly connected section 5, the adaptation that matches with the circular groove size of interlocking of its size, the trepanning that end face bored 6 in axially locating section 4 generally is drilled to monolateral hole, put into spring 2 and pellet shot from a slingshot 3 in the hole respectively, for preventing that pellet shot from a slingshot 3 from coming off, during assembling, can do back riveting slightly, pellet shot from a slingshot 3 is limited in the hole at nose end.Certainly, also trepanning 6 can be drilled to through hole, like this need be at end face seal cap screw.
Claims (4)
1, can axially reach the locating stud of circumference rotation positioning, be diaxon be nested connect to cooperate in the time of need making axially locating and circumference activity rotation positioning laterally inserted to the two relative positioning devices that cooperate discs, it is characterized in that it includes a shank (1), spring (2) and pellet shot from a slingshot (3); (1) is divided into fixedly connected section (5) and axially locating section (4) on shank, offers a trepanning (6) at shank (1) axially locating section (4) end face.
2, the locating stud that can axially reach the circumference rotation positioning according to claim 1 is characterized in that, spring (2) and pellet shot from a slingshot (3) place in the trepanning (6).
3, the locating stud that can axially reach the circumference rotation positioning according to claim 1 is characterized in that, is processed with screw thread on fixedly connected section (5) of shank.
4, the locating stud that can axially reach the circumference rotation positioning according to claim 1 is characterized in that, trepanning (6) is monolateral hole or through hole.
