Abstract

The utility model relates to a dead bolt structure which comprises a dead bolt and a locating piece. The dead bolt is provided with a spindle unit, an elastic unit and a barb unit; the elastic unit is installed at one end of the spindle unit and elastically presses on the surface of a plate which is fixedly connected with the dead bolt; the barb unit is molded at the other end of the spindle unit; the locating piece is provided with a spindle hole and an against-pressing unit; the spindle hole is molded corresponding to the spindle unit and the against-pressing unit is formed in the spindle hole; the spindle unit of the dead bolt passes through the hole and the against-pressing unit is hooked with the barb unit; therefore, the elastic unit presses on the plate which is fixedly connected with the elastic unit and provides proper elasticity so as to adapt to the length of the spindle hole of the locating piece and to ensure that the barb unit is properly locked with the against-pressing unit, thereby enhancing the stability of the fixed connection of the dead bolt and preventing the dead bolt from releasing due to vibration or other improper external forces.

Description

The gim peg structure

Technical field

The utility model relates to a kind of gim peg structure, relates in particular to a kind ofly can be arranged in keeper to make the structure of the affixed combination of object by gim peg.

Background technology

Connection between the gim peg specific responsibility member, can cooperate positioning piece to make firm being incorporated on another member of a member, be generally positioned at the housing inner edge surface of computer housing as circuit board, and carry the electronic package of many precisions on the circuit board usually, therefore, how the suitable circuit board that makes is fixed in housing, is an important problem in fact.

Seeing also Fig. 1 and Fig. 2 is the existing fixed stud structure, it comprises a gim peg 1a and positioning piece 2a, this gim peg 1a is to being provided with by keeper 2a, this gim peg 1a has a head 11a, an axial region 12a and a 13a of barb portion, this head 11a takes shape in the end of this axial region 12a, and the 13a of this barb portion takes shape in the other end of this head 11a relatively.

This keeper 2a has a head 21a, an axis hole 22a, a butting section 23a and a clamping part 24a, this axis hole 22a is arranged at this head 21a centre, this butting section 23a be to should the 13a of barb portion taking shape in this axis hole 22a suitably distance, and this clamping part 24a takes shape on the other end of the keeper 2a of this head 21a relatively.

This keeper 2a is inserted in the housing 3a of a computer housing, and this head 21a is resisted against the edge face of this housing 3a, and this clamping part 24a clip is in this housing 3a another side.This gim peg 1a is inserted in one and is the plate body 4a of circuit board, and this head 11a is resisted against on this plate body 4a, and this axial region 12a is inserted in this axis hole 22a, and makes the 13a of this barb portion collude placing on the 23a of this butting section.

So, the dimensions of this keeper 2a may not meet should gim peg 1a, thereby makes being inserted in this keeper 2a that this gim peg 1a can't be firm, if so bear the effect of vibration or other improper external force, deviates from phenomenons such as separation most probably.

As shown in Figure 1, if the axis hole 22a axial length of this keeper 2a is long than the axial region 12a of this gim peg 1a, then the 13a of this barb portion can't right-on barb on the 23a of this butting section, cause being inserted in this keeper 2a that this gim peg 1a can't be firm, and the phenomenon of deviating from easily.

As shown in Figure 2, if the axial region 12a of this gim peg 1a is long than the axis hole 22a of keeper 2a, when cooperating, the 13a of this barb portion can't be resisted against on the 23a of this butting section, and can produce a gap each other, causes this gim peg 1a and can produce the phenomenon that teetertotters.
