Common buckling device kind is a lot, is wherein a kind of as shown in Figures 1 and 2.This buckling device 9 is formed by sheet metal integrated punching bending, have that a level is horizontally set with by branch 2, by branch 2 two ends extend a shell fragment 3 respectively obliquely, each shell fragment 3 end extends side plate 4 downwards.All form low opening 5 and a higher opening 6 on each side plate 4, low opening 5 is on the projection (not label) that is snapped in connector 8 sides, the lamellar body 7 and root edge of higher opening 6 extends outwardly out obliquely can be installed and removed this buckling device 9 by instrumental purpose in this higher opening 6 or lamellar body 7.But, the structure of common this buckling device 9 is very firm and be difficult for deflection, need just can carry out by the auxiliary of other instrument when assembling or dismounting, complicated operation and efficient are not high, and, in utilizing the process of tool operation,, very easily cause instrument to skid and damage other assemblies such as motherboard of computer-internal if application of force control is improper.

The purpose of this utility model is to provide a kind of easy, button solid buckling device that keeps steady of installing and removing.

In order to achieve the above object, the utility model has adopted following technical scheme: the utility model buckling device comprises a press body and an operating body.These press body central authorities are provided with a butting section, the two ends, butting section are extended one respectively obliquely and are had suitable flexible shell fragment, wherein the end of a shell fragment extends the first buckle arm downwards, and extend a junction under another shell fragment terminal oblique, the terminal both side edges of this connecting portion turnover up respectively vertically bends out a bracing frame, all offers a cam-like chute on each bracing frame.This operating body is formed by the rectangular integrated punching bending of metal, both side edges of appropriate position laterally protrudes out a drive-connecting shaft respectively in the middle of it towards both sides, this drive-connecting shaft can insert in the cam-like chute on this bracing frame and this operating body and press body are linked together, and this drive-connecting shaft can slide in this chute.The top of this operating body bends outwardly and obliquely and extends to form a press section, and the bottom extends to form the second buckle arm downwards.

Hold strength because the utility model just can change button by the variation of drive-connecting shaft on relative position, so install and remove conveniently, button keeps steady solid.

The utility model is described in further detail in conjunction with the embodiments with reference to the accompanying drawings:

Fig. 3 is the three-dimensional exploded view of the utility model buckling device.

Fig. 4 is the three-dimensional combination figure of the utility model buckling device.

Fig. 5 is before the start of the utility model buckling device and the three-dimensional combination figure of associated component.

When Fig. 6 is the start of the utility model buckling device and the stereographic map of associated component.

Fig. 7 be after the start of the utility model buckling device with the three-dimensional combination figure of associated component.

Please together consult Fig. 3 to Fig. 7, the utility model buckling device 1 is to be positioned in the groove 42 of heating radiator 40, and by and the fastening of 52 of the dual-side projections of connector 50, and this heating radiator 40 is fixed on the central processing unit (not label), wherein, this buckling device 1 mainly comprises a press body 10 and an operating body 30.

These press body 10 central authorities are provided with a

butting section

12,12 two ends, butting section are extended one respectively obliquely and are had suitable flexible shell fragment 14, wherein the end of a shell fragment 14 extends the first buckle arm 16 downwards, and this first buckle arm 16 is provided with first button hole 18 that is used for a side projection 52 corresponding snappings of connector 50; Extend a junction 22 under another shell fragment 14 terminal oblique, the terminal both side edges of this connecting portion 22 turnover up respectively vertically bends out a bracing frame 24, all offers a cam-like chute 26 on each bracing frame 24.

This operating body 30 is formed by the rectangular integrated punching bending of metal, both side edges of appropriate position laterally protrudes out a drive-connecting shaft 32 respectively in the middle of it towards both sides, this drive-connecting shaft 32 can insert in the cam-like chute 26 on this bracing frame 24 and this operating body 30 is linked together with press body 10, and this drive-connecting shaft 32 can slide in this chute 26 (please refer to Fig. 4).The bending outwardly and obliquely of the top of operating body 30 extends to form the press section 34 at application of force place when being used as operation.The bottom of operating body 30 extends to form the second buckle arm 17 downwards, and this second buckle arm 17 is provided with second button hole 19 that is used for another side projection 52 corresponding snappings of connector 50.In addition, the top both side edges of this operating body 30 turnover inwardly respectively vertically bends out reinforced sheet 36 in, and the both side edges at middle part and one segment distance place, below thereof respectively turnover outwardly vertically be bent into outer reinforced sheet 38, to reach outer reinforced sheet 38 are the structural strengths that are used for increasing operating body 30 to reinforced sheet 36 in this.

(please together consult Fig. 5 to Fig. 7) during assembling, earlier buckling device 1 is positioned in the groove 42 of heating radiator 40, and making first button hole 18 of buckling device 1 and the dual-side projection 52 that second button hole 19 catches on connector 50 respectively, this moment, this first button hole 18 and second button hole 19 did not also realize closely fastening (please refer to Fig. 5) with projection 52.Then, pull the press section 34 of this operating body 30, make on the operating body 30 drive-connecting shaft 32 relatively the minimum point A points in the cam-like chutes 26 from press body 10 bracing frames 24 upwards cross peak B point (please refer to Fig. 6) and slide always and drop to and just finish assembling than low spot C point (please refer to Fig. 7), because this drive-connecting shaft 32 is in sliding process, its relative position is to change to the C point by the A point, change relatively and just cause like this to produce between the one-piece construction of this buckling device 1, thereby increase this first button hole 18 and second button hole 19 catches on the strength of projection 52 and realizes tight fastening, wherein, this peak B design of ordering can prevent that drive-connecting shaft 32 is from than improper the returning of low spot C point.

During dismounting, oppositely pull the press section 34 of this operating body 30, and make on the operating body 30 drive-connecting shaft 32 relatively the C points in the chute 26 pass through the B points and be retracted into the A point, just can remove the tight fastening of 52 of first button hole 18, second button hole 19 and projections and finish dismounting quickly and easily.
