Fig. 4 is the structural representation of clamp clip.
Embodiment
Below in conjunction with the drawings and specific embodiments, the utility model is described in further detail:
Dowel device, comprising: location shank 1, positioning pin handle 2, adjustment pad 3, clamp clip 4.
As shown in Figure 1, 2, shank 1 one end, described location is cylindrical structure, and diameter is consistent with by positioning hole diameter; End is 30 ° of chamferings; Cylndrical surface has two symmetrical notchs, and draw-in groove basal spacing and clamp clip opening size match, and clamp clip 4 can insert in draw-in groove; The other end of said location shank 1 is external thread structure, realizes screw-thread fit be connected with the internal thread of positioning pin handle 2.Location shank 1 and positioning pin handle 2 are threaded connection as a whole.
As shown in Figure 3, described positioning pin handle 2 comprises handle body 5 and handle 6.Handle body 5 is cylindrical hollow structure, and inside is internal thread, and the outside thread of size and location shank 1 matches; One end has through-hole structure, and handle 6 matches.Handle 6 is cylindrical structure, and the through hole of handle body 5 one end matches to merge to insert in through hole and forms integrative-structure.
Described adjustment pad 3 is and the pad that is used in combination of outside thread of location shank.
Described clamp clip 4 is panel beating class formation, one end has hatch frame, see Fig. 4, on A/F and location shank 1, two symmetrical draw-in groove basal spacings match, and the spacing L ' on A/F L and location shank 1 between two axially symmetrical groove bottom lands meets following relation: L-L ' is 0.5 ~ 1.5mm.The other end is used for hand-held, be bending structure, and portareapiston is 20 ° of angles.
During use, comprise the following steps:
1) location shank 1, positioning pin handle 2 are carried out screw-thread fit connection;
2) location shank 1 is inserted in the positioning hole by locating piece.
3) check on the shank 1 of location, whether draw-in groove exposes completely by locator surface.If nothing, again insert draw-in groove on the shank 1 of in positioning hole until location after location shank 1 and positioning pin handle 2 being unclamped and expose completely.
