[summary of the invention]

Technical matters to be solved by this invention is to provide a kind of fixer for heat radiator that heating radiator can be fixed to the circuit board with different fastening structures.

Technical matters to be solved by this invention is achieved through the following technical solutions: fixer for heat radiator of the present invention, be used for a heating radiator is fixed to circuit board, this stationary installation comprises a body frame, be articulated with at least one pair of first fastener and at least one pair of second fastener on this body frame, described first fastener pivots in being parallel to the plane of this body frame and is in collapse state or extended configuration with respect to this body frame, and described second fastener pivots in perpendicular to the plane of this body frame and is in collapse state or extended configuration with respect to this body frame.

Compared with prior art, fixer for heat radiator of the present invention has first, second fastener that can fold or stretch, thereby heating radiator can be fixed on the circuit board with different fastening structures.

Below with reference to accompanying drawing, in conjunction with the embodiments the present invention is further described.

[embodiment]

See also Fig. 2, fixer for heat radiator 10 of the present invention comprises a square body frame 20 and is articulated in some fasteners of this body frame 20.

The central authorities of body frame 20 are provided with an opening 22 and center on the four side 23 of opening 22, and proximal edge place, relative both sides respectively establishes a pair of upwards contiguous block 24 of projection on the body frame 20, and these fasteners comprise 4 first fasteners 30 and 2 second fasteners 40.These first fasteners 30 are articulated in four jiaos of body frame 20, respectively offer one on body frame 20 lateral margins in contiguous first fastener 30 places and are articulated in the contiguous block 24 of body frame 20 with fluting 26, the second fasteners 40 of accommodating first fastener 30.The structure of this first fastener 30 and second fastener 40 is basic identical.

See also Fig. 3, second fastener 40 comprises a pair of side plate that separates 41, first articulated part 45 and a screw 47.One end of side plate 41 extends to form one second articulated part 43, and the root edge of side plate 41 extends to form on a baffle plate 42, the first articulated parts 45 and is outward extended with the linking arm of opening in two minutes 46.During assembling, screw 47 is placed in the linking arm 46 of first articulated part 45, and first articulated part 45 is articulated on the side plate 41.Screw 47 can be parallel to side plate 41 (as shown in Figure 4) around first articulated part 45 and rotate between perpendicular to side plate 41 (as shown in Figure 5) position, when screw 47 is parallel to side plate 41, it is contained in 41 of biside plates, and do not interfere other element, when screw 47 during perpendicular to side plate 41, linking arm 46 is kept out on baffle plate 42, and screw 47 is remained on this position, thereby screw 47 is locked on the circuit board (figure does not show).

First fastener 30 and second fastener 40 all can rotate with respect to body frame 20, first fastener 30 can rotate in the plane that is parallel to body frame 20, then be in collapse state in the time of in it is contained in fluting 26, when it then is in extended configuration when four jiaos of body frame 20 open, second fastener 40 can rotate in the plane perpendicular to body frame 20, then be in collapse state when it turns to when vertically standing on the body frame 20, when 20 liang of relative edge's edge of body frame open, then be in extended configuration when it is parallel to body frame 20.As shown in Figure 2, first fastener 30 and second fastener 40 all are in extended configuration, as shown in Figure 4, first fastener 30 is in extended configuration, and second fastener 40 is in collapse state, and as shown in Figure 5, first fastener 30 is in collapse state, and second fastener 40 is in extended configuration, thereby makes stationary installation 10 applicable to the circuit board with different fastening structures.
