Description
Technical field
The utility model relates to a kind of connection fastener, relates in particular to a kind of connection fastener that fan is locked admittedly or is connected in series that is used for.The utility model also relates to the fan component that adopts this connection fastener.
Background technique
Electronic product as personal computer and server and so on need use fan to dispel the heat.Existing fan has rectangular enclosure greatly, and the straight ends of shell has mounting hole, can use screw to lock fan admittedly or is connected in series each fan.
Because the not easy-to-use screw locking of structure of fan drum is so also can finish the solid lock or the serial connection of fan with trip or plastic fastener by shell.Please refer to Fig. 1, existing fastener 10 has the groove 103 between force section 101, blocked part 109, at least one rib 102 and the rib 102.Fastener 10 is when passing the mounting hole of fan drum, and the user makes rib 102 enter mounting hole by force section 101 application of forces, and blocked part 109 is contacted with this mounting hole lateral margin, thereby finishes the solid lock of fan.Buffer space when groove 103 is squeezed for rib 102 enters mounting hole.
Yet the shortcoming of existing fastener is that solid lock degree is not good.During especially for the solid lock of fan or serial connection, because fan makes existing fastener come off easily because of the vibrations that rotation produces in use.Therefore, how to avoid fastener to come off and can become important problem at present according to the easy dismounting of user's demand.
The model utility content
The purpose of this utility model is to provide a kind of connection fastener that can be used for the locking or the binding of fan, and this fastener can make fan difficult drop-off and dismounting easily when locking or binding.
Another purpose of the present utility model is to provide the fan component that adopts this connection fastener.
According to one side of the present utility model, a kind of connection fastener is provided, it comprises force section, blocked part, at least one rib and at least one groove.The blocked part be positioned at the force section around, rib extends from the force section, each groove is between rib, the end of rib has a protuberance.
According to the utility model on the other hand, provide a kind of fan component, it comprise at least one desk fan, above be provided with the pedestal of fan; And at least one fastener in order to winding fan and pedestal.This fastener comprises force section, blocked part, at least one rib and at least one groove, the blocked part be positioned at the force section around, rib extends from the force section, each groove is between rib; And the end of rib has a protuberance.
Preferred force section, blocked part, rib and protuberance may be molded to one; Fastener can be made of plastics.
The profile of preferred force section is rounded substantially; Can make rib be radial arrangement.
The central authorities of preferred force section have a through hole, and this through hole is used for further locking by screw.
Preferred fan is many, and the fan frame of each fan has at least one mounting hole, and mounting hole toward each other; Described fastener is a plurality of, in order to described fan of winding and pedestal.
The length of preferred rib equals the twice of the degree of depth of mounting hole substantially.
Preferred protuberance passes outside the mounting hole facing each other, and the outer rim of blocked part and mounting hole offsets.
Adopt connection fastener provided by the utility model, because the length of rib between blocked part and protuberance equals the twice of the fan drum mounting hole distance desiring to wear substantially, protuberance can pass outside the mounting hole and the outer rim of blocked part and mounting hole is offseted, thereby fastener is difficult for getting loose.When need being available for users to, through hole further uses screw locking.

Embodiment
The following mode of execution that connection fastener of the present utility model is described with reference to relevant drawings.
Fig. 2 shows first mode of execution of fastener of the present utility model.Fastener 20 has the groove 203 between force section 201, blocked part 209, at least two ribs 202 and the adjacent rib 202.Force section 201 central authorities have through hole 205, and the end of rib 202 has protuberance 204.Force section, blocked part, rib and protuberance are one-body molded and be preferably plastics and make.In the present embodiment, the profile of force section 201 is roughly circle, and its diameter is greater than the diameter of the fan drum mounting hole of desiring to wear.The length d 1 of rib 202 between blocked part 209 and protuberance 204 equals two times of the fan drum mounting hole distance desiring to wear, close-fitting when being beneficial in conjunction with fan substantially.
Groove 203 can be used as rib 202 and enters buffer space when being squeezed behind the mounting hole.In the present embodiment, the quantity of rib 202 and groove 203 is similarly two.Fastener of the present utility model also can only have single groove, and promptly the rib transverse section is the ring-type with breach, as long as protuberance can obtain buffer space by groove when being squeezed.
Fig. 3 shows second mode of execution of fastener of the present utility model.Fastener 30 has the groove 303 between force section 301, blocked part 309, at least one rib 302 and the adjacent rib 302.Force section 301 central authorities have through hole 305, and the end of rib 302 has protuberance 304.In the present embodiment, the profile of force section 301 is rounded substantially, and its diameter is greater than the diameter of the fan drum mounting hole of desiring to wear.The length d 1 of rib 302 between blocked part 309 and protuberance 304 equals two times of the fan drum mounting hole distance desiring to wear, close-fitting when being beneficial in conjunction with fan substantially.
Groove 303 can be used as rib 302 and enters buffer space when being squeezed behind the mounting hole.What be different from first mode of execution of the present utility model is that the rib 302 of present embodiment and the quantity of groove 303 are three.In other words, these grooves 303 make described rib 302 be radial arrangement.
Certainly, the quantity of the rib of fastener of the present utility model and groove is not limited to two or three.Extruded buffer space when as long as groove can play rib and enters the mounting hole of desiring to wear.
To further specify the mode of execution that connection fastener of the present utility model is used for tandem fan with Fig. 4 below.As shown in Figure 4, the fan frame of general fan F has on outer rim that thickness is d2 and this fan frame and has mounting hole 5.When desiring with fastener 20 of the present utility model with the series connection of two fans, mounting hole 5 at fan in twos passes relative mounting hole 5 with fastener 20 earlier in the back relatively, because the length d 1 of the rib 202 of fastener 20 equals two times of the fan outer rim thickness d 2 desiring to wear substantially, so protuberance 204 can pass outside the two relative mounting holes 5 and the blocked part 209 and the outer rim of mounting hole 5 are offseted, thereby fastener 20 is difficult for getting loose.When need being available for users to, through hole 205 further uses screw locking.In mode of execution shown in Figure 4, also can utilize fastener 30 to carry out the combination of fan F, combination is identical with fastener 20, does not repeat them here.
Fastener of the present utility model is not limited to be used in the series connection of two desk fans, also can be used for the fixing of fan and other pedestal.In addition, the through hole that fastener of the present utility model has also is available for users to carry out secondary locking with screw, and the vibrations that this fastener produces when being difficult for because of fan running come off.
Below only preferred implementation of the present utility model is described, these mode of executions only in order to the present invention will be described are not is to restriction of the present utility model, under the prerequisite that does not exceed design of the present utility model and scope, can make various changes and retouching to it, therefore, scope of the present utility model is defined by the following claims.All equivalents that the utility model is made all should fall in the scope that claim contains with modifying.
