Abstract
The utility model relates to a combination of a positioning pin and a positioning cap. The combination of the positioning pin and the positioning cap is characterized in that a positioning pin body is a cylindrical body, a pin head which is larger than the cylindrical body in diameter is arranged at one end of the positioning pin body, a groove is arranged at the end portion of the pin head, a screw driver can be inserted into the groove, and one to three L-shaped grooves which are in rotational symmetry are formed on the surface of the other end portion of the cylindrical body. The positioning cap is provided with an inner round hole which is equal to the cylindrical body in diameter, protruding teeth which are equal to the L-shaped grooves in number are arranged on the arc face of the inner round hole, the protruding teeth can be inserted and rotated into the L-shaped grooves, the protruding teeth and the L-shaped grooves can be mutually locked, and a rotation stopping section is arranged on the outer edge of the positioning cap. By means of the match of the L-shaped grooves on the positioning pin and the protruding teeth on the positioning cap, the purposes that parts can be locked, dismounted and mounted quickly are met, in addition, the positioning pin can be used as a rotating shaft between parts, the two parts can be positioned, rotation between the two parts is permitted, and the positioning pin can be widely used on plastic products and other products as a positioning component and the rotating shaft.
Description
Technical field:
The utility model belongs to fastener areas, particularly a kind of locating stud of easy disassembly, cap combination.
Background technique:
Existing fastening piece is commonly referred to as bolt and nut has made up, and uses the most extensively, also conveniently is easy to get, but also its deficiency not, namely easily get rusty and for a long time with easily getting loose, especially on the article in wet environment, reduce the use of irony bolt at plastic article or use as far as possible.For this reason, seek new replacement scheme, namely become the object of the utility model research.
Summary of the invention:
To be that design is a kind of form L shaped groove by the pin end and coordinate with cap convex tooth the purpose of this utility model, and locating stud, the cap of energy quick lock in make up.
Technical solutions of the utility model are achieved in that a kind of locating stud, cap combination, it is characterized in that the locating stud main body is cylindrical structure, one end is provided with the diameter plunger large than cylinder diameter, the plunger end is provided with the groove that inserts for screw-driver, and cylindrical body the other end surface forming has one to three to become rotational symmetric L shaped groove; Positioning cap has the interior circular hole suitable with cylinder diameter, and inner circle hole circle cambered surface is provided with the protruding tooth that number equates with L shaped groove number, and this protruding tooth can be inserted and rotated in L shaped groove, forms mutual locking relation, and described positioning cap outer has the spline tangent plane.Coordinate with the protruding tooth of positioning cap by the L shaped groove on locating stud, reach quick lock between part and the purpose of dismounting.
Described L shaped groove comprises and the pod of cylindrical body parallel to an axis and the curve bath parallel with end face, and the groove of this curve bath proximal end face one side is along having a pit; The protruding tooth of described positioning cap and this curve bath pit resistance surface have arc convex, and both coordinate the formation spline structure.
Described L shaped groove comprises and the pod of cylindrical body parallel to an axis and the curve bath parallel with end face, and the groove of proximal end face one side of pod and curve bath corner is along having a lug boss; The protruding tooth of positioning cap is limited in curve bath after slipping over this lug boss when rotating.
Described positioning cap outer is round structure, and is provided with two parallel spline tangent planes.By two spline tangent planes, when positioning cap is embedded in part, form spline structure, facilitate locating stud to insert the rotational lock operation.
The utlity model has novel structure, the characteristics that reasonable in design, lock operation is easy, and this locating stud can use as the rotating shaft between part, two relations between part both can have been located, can allow again spinning movement between the two, can be widely used on the product such as plastic cement, use as locating piece and rotating shaft.

Embodiment:
See figures.1.and.2, locating stud, cap combination, comprise locating stud 1 and positioning cap 2, its locating stud 1 main body is cylindrical structure, one end is provided with the diameter plunger 11 large than cylinder diameter, plunger 11 ends are provided with the groove 12 that inserts for screw-driver, and cylindrical body the other end surface forming has one to three to become rotational symmetric L shaped groove 13; This L shaped groove 13 comprises and the pod 131 of cylindrical body parallel to an axis and the curve bath 132 parallel with end face, and the groove of these curve bath 132 proximal end face one sides is along having a pit 133;
Positioning cap 2 has the interior circular hole 21 suitable with cylinder diameter, interior circular hole 21 arc surfaces are provided with the protruding tooth 22 that number equates with L shaped groove 13 numbers, pit 133 resistance surfaces in protruding tooth 22 and described curve bath have arc convex 220, and both coordinate the formation spline structure.Positioning cap 2 outers are round structure, and are provided with two parallel spline tangent planes 23.
During assembling, in the counterbore of first part of first positioning cap 2 being packed into, utilize spline tangent plane 23 to coordinate with counterbore, keep positioning cap 2 can not rotate; Again locating stud 1 is inserted from the axle eye of the second part, suitably the protruding tooth 22 in the pod 131 aligning positioning caps that make the cylindrical body end is regulated in rotation, insert and rotate a small angle, make the arc convex 220 on protruding tooth 22, by the resiliently deformable of curve bath 132, slip in the pit 133 of locating stud, namely form both and locate reliably, and locating stud 1 can be worked as rotating shaft and be used, and makes two part rotations freely.
The spline positioning relation of locating stud 1 and positioning cap 2, also can adopt following structure: also namely at the groove of the pod 131 of L shaped groove 13 and proximal end face one side of curve bath 132 corners along having a lug boss; The protruding tooth 22 of positioning cap 2 is limited in curve bath after slipping over this lug boss when rotating.
Locating stud and positioning cap can be selected different materials according to the different application occasion, to satisfy anticorrosion and requirement intensity.
