Abstract

A fan fixed mount includes a square horizontal part and four flexible support legs respectively extending from four corners adjacent to the horizontal part. The flexible support legs are made by the opposite-side adjacent corners of the horizontal part extending aslant upward and then extending downward. The bottom of each support leg is extended into a barb. A reinforcing rib is arranged between two flexible support legs at the same side. The centers of the two opposite sides from which the flexible support legs are extended are respectively extended downward into a retaining plate; the hemline of each retaining plate is respectively extended inward into a raised strip. The centers of the other opposite sides of the horizontal part are respectively extended into an edge fold.

Description

Fan Fixture

The utility model is about a kind of fan Fixture, particularly keeps steady admittedly and easy fan Fixture about a kind of button.

Along with developing rapidly of computerized information industry, the arithmetic speed of central processing unit (CPU) is more and more faster, and the heat that it produced is also more and more, and too much heat is if can't in time discharge, the stability when having a strong impact on the central processing unit (CPU) operation.For this reason, industry is installed an aluminium extruding radiator with the central processing unit (CPU) end face usually and is added that the assemblying body of fan assists to discharge heat.Usually adopt fan is fixed on the radiator mode as shown in Figure 1, it is attacked on the radiating fin 102 of radiator 100 and establishes screw thread, and by screw 200 with fan 300 screw locks on the radiating fin 102 of radiator 100.But, along with the heat that central processing unit (CPU) produces is more and more, need the depth-width ratio of radiating fin increasing, therefore radiating fin is more and more thinner, and the mode of this fan attachment that adopts usually very easily causes the radiating fin distortion, thereby sliding dental phenomenon takes place, and in the process of locking nut, very easily produce the aluminium bits, influence radiating effect.Correlation technique in addition also can be with reference to Taiwan patent application the 85207163rd and No. 86216714 etc.

Therefore, how to provide a kind of button to keep steady admittedly and easy fan means of fixation, be problem to be solved in the utility model.

The purpose of this utility model is to provide a kind of button to keep steady admittedly and easy fan Fixture.

For achieving the above object, the utility model has adopted following technological scheme: the utility model fan Fixture is one-body molded by sheet metal, four flexible feets that it has a square horizontal part and extends respectively from contiguous four corners of this horizontal part.These horizontal part central authorities offer a hole, this flexible feet extends behind the segment distance more oppositely bending down respectively obliquely by place, contiguous corner, the two opposite sides of horizontal part and extends and form, and the end of each flexible feet further extends one and bending barb upwards inwardly, in addition, this flexible feet several angle that tilts relatively inwardly makes it have suitable elasticity.Between two flexible feets of homonymy, also be provided with a strengthening rib that this two flexible feet is connected as a single entity, thereby strengthen the structural strength of this flexible feet.This horizontal part extends a catch respectively downwards extending the two opposite sides central authorities of this flexible feet, and the root edge central authorities of each catch extend a raised line respectively inwardly.This horizontal part is extending the two opposite sides central authorities in addition of this flexible feet, extend one respectively downwards and be used for strengthening the flanging that fan is decided the frame overall construction intensity, influence button to prevent this fan Fixture from when finishing fastener, arching upward metaboly and hold strength.

Compared with prior art, the utility model fixes fan by fan Fixture, does not need to use screw, establishes screw thread nor need attack on the radiating fin of radiator, so radiating fin can not be out of shape, and also can not produce the aluminium bits.

Below in conjunction with drawings and Examples the utility model is specifically described:

Fig. 1 is the three-dimensional combination figure of the fan means of fixation of available technology adopting.

Fig. 2 is the three-dimensional exploded view of the utility model fan Fixture and radiator and fan.

Fig. 3 is the stereogram of the utility model fan Fixture.

Fig. 4 is the three-dimensional combination figure of the utility model fan Fixture and radiator and fan.

See also Fig. 2, the utility model fan Fixture 10 is used for fan 30 is fixed on the radiator 40.This fan 30 has the cylindrical body 34 that a base 32 and is convexly set in these base 32 central authorities.This radiator 40 has a pedestal 42 and some radiating fins 44 that extends on this pedestal 42 parallel to each other, and the both sides, bottom surface of this pedestal 42 are respectively equipped with one and are parallel to the microscler groove 422 that radiating fin 44 extends.In this radiating fin 44, be positioned at outermost two radiating fins 44 and be higher than other radiating fin 44 in the middle of being positioned at, form the concave shaped space (not label) that the base 32 of air feed fan 30 is placed in the crown center zone, and suitably limit this fan 30.In addition, this radiating fin 44 is at the common long and narrow groove 442 perpendicular to radiating fin 44 extensions that forms of central authorities.

Please together consult Fig. 3, the utility model fan Fixture 10 is one-body molded by sheet metal, four flexible feets 14 that it has a square horizontal part 12 and extends respectively from these horizontal part 12 contiguous four corners.The bottom surface of this horizontal part 12 is fitted in the end face of fan 30 bases 32, and horizontal part 12 central authorities offer the hole 16 that the cylindrical body 34 of air feed fan 30 passes; This flexible feet 14 extends behind the segment distance more oppositely bending down respectively obliquely by place, contiguous corner, the two opposite sides of horizontal part 12 and extends and form, and the end of each flexible feet 14 further extends one and bending barb 18 upwards inwardly, come in the groove 422 of fastener on radiator 40 pedestals 42 bottom surfaces, in addition, this flexible feet 14 several angle that tilts relatively inwardly makes it have suitable elasticity.Between two flexible feets 14 of homonymy, also be provided with a strengthening rib 20 that this two flexible feet 14 is connected as a single entity, thereby strengthen the structural strength of this flexible feet 14.This horizontal part 12 is extending the two opposite sides central authorities of this flexible feet 14, extend a catch 22 respectively downwards, the root edge central authorities of each catch 22 extend a raised line 24 respectively inwardly, this raised line 24 probes in 44 common long and narrow grooves 442 that form of some radiating fins of radiator 40, relatively moves improperly to prevent that this fan Fixture 10 from producing on the direction that is parallel to radiating fin 44 extensions.This horizontal part 12 is extending the two opposite sides central authorities in addition of this flexible feet 14, extend a flanging 26 that is used for strengthening the overall construction intensity of fan Fixture 10 respectively downwards, influence button to prevent this fan Fixture 10 from when finishing fastener, arching upward metaboly and hold strength.

Please together consult Fig. 4, during installation, earlier the base 32 of fan 30 is placed in the concave shaped space (not label) in radiator 40 crown center zones, then, with the from top to bottom sheathed firmly cylindrical body 34 of fan 30 of fan Fixture 10, make the bottom surface of fan Fixture 10 horizontal parts 12 be fitted in the end face of fan 30 bases 32, and make in the groove 422 of barb 18 fasteners on radiator 40 pedestals 42 bottom surfaces on fan Fixture 10 flexible feets 14, being about to this fan 30 firmly and easily is fixed on the radiator 40, raised line 24 on this fan Fixture 10 probes in 44 common long and narrow grooves 442 that form of some radiating fins of radiator 40 at this moment, relatively moves improperly to prevent that this fan Fixture 10 from producing on the direction that is parallel to radiating fin 44 extensions.
