For solving the problems of the technologies described above, the technical solution of the utility model is:
A kind of hot-plug fan stationary installation of exempting from instrument dismounting, comprise the PCB support that is fixedly installed on wind inlet of fan side, be fixedly installed on successively fan fixed network and the blower tray of fan outlet side, described fan fixed network comprises middle wet end and the fixing flexure strip of middle wet end four avris, the stiff end of described flexure strip is fixedly connected with middle wet end, the also outward-dipping setting contrary to installation direction of its free end, on the flexure strip of the relative both sides of described middle wet end, be provided with buckle projection, described buckle projection one end is connected with described flexure strip, the other end is along the reverse direction projection gradually of installation direction, the convex side of described buckle projection is also fixedly connected with press section, described blower tray is provided with intilted blocking part in inner side, described press section.
Preferably, each avris of described middle wet end is fixedly installed three described flexure strips, and being positioned on middle described flexure strip of the relative both sides of described middle wet end is provided with buckle projection.
Preferably, described PCB support, fan fixed network and blower tray are screwed on described fan.
Preferably, described fan fixed network adopts stainless steel, and described blower tray adopts plated steel sheet.
Technique effect of the present utility model is as follows: the utility model adopts multiple flexure strips of the setting on fan fixed network and the inwall of cabinet to fix, more flexible fastening power can be provided, and be buckled in pars intramuralis in cabinet by buckle projection, can prevent that this device is being installed into after cabinet to outer movement, and on the blower tray of described fan fixed network rear side, be provided with blocking part, excessively cause damage to keep in the center for preventing that flexure strip that press section connects is bent.
Brief description of the drawings
Fig. 1 is the three-dimensional exploded view of an embodiment of the utility model;
Fig. 2 is the stereographic map of the utility model fan support;
Fig. 3 is the side view of the utility model fan fixed network;
Fig. 4 is the upward view of the utility model fan fixed network.
Wherein: 1-fan, 2-fan fixed network, 3-blower tray; 4-PCB support, 5-screw, 21-buckle projection, 22-press section, 23-flexure strip, wet end in 24-, 31-blocking part.
Embodiment
Below in conjunction with drawings and Examples, the utility model is further illustrated.
As shown in Figure 1, for meeting a kind of hot-plug fan stationary installation of exempting from instrument dismounting of the present utility model, comprise the PCB support 4 that is fixedly installed on fan 1 air inlet side, described PCB support 4 can be for being fixedly connected with, can also be used for the electric wire of fan 1 to realize with the circuit in cabinet the intermediary being electrically connected, be fixedly installed on successively fan fixed network 2 and the blower tray 3 of fan 1 air outlet side, described fan fixed network 2 comprises middle wet end 24 and the fixing flexure strip 23 of middle wet end 24 4 avris, flexure strip 23 is set respectively on described middle wet end 24 4 limits and can ensures to provide more for fixing elastic force, after being entered, fan 1 installation can provide larger bed knife, the stiff end of described flexure strip 23 is fixedly connected with middle wet end 24, the also outward-dipping setting contrary to installation direction of its free end, on the flexure strip 23 of the relative both sides of described middle wet end 24, be provided with buckle projection 21, as shown in Figure 3 and Figure 4, described buckle projection 21 one end are connected with described flexure strip 23, the other end is along the reverse direction projection gradually of installation direction, like this when this is novel while being installed in cabinet, the sidewall of cabinet can touch the flexure strip 23 the inside elasticity of compression sheet 23 that tilt laterally, when it moves along installation direction gradually along buckle projection 21, finally can exceed the peak of described buckle projection 21, at this moment described buckle projection 21 can be buckled in the inwall of cabinet, prevent that fan 1 from outwards moving, the convex side of described buckle projection 21 is also fixedly connected with press section 22, in the time wanting to dismantle fan 1, press described press section 22, can inwardly shrink the flexure strip 23 that is provided with buckle projection 21, then outwards can pull out this fan fixer, because described blower tray 3 is arranged on described fan fixed network 2 inner sides, described blower tray 3 is provided with intilted blocking part 31 in 22 inner sides, described press section, as shown in Figure 2, described blocking part 31 is pressed towards enterolithic flexure strip 23 for keeping out, because if firmly excessive, flexure strip 23 is excessive to enterolithic angle, flexure strip 23 can not be got back to origin-location, do not have good fixation, therefore the blocking part 31 arranging both can ensure that flexure strip 23 bent certain angle, being unlikely to again damaged causing cannot reset.
In a preferred embodiment, each avris of described middle wet end 24 is fixedly installed three described flexure strips 23, and being positioned on middle described flexure strip 23 of described middle wet end 24 relative both sides is provided with buckle projection 21.
In a preferred embodiment, described PCB support 4, fan fixed network 2 and blower tray 3 are fixed on described fan 1 by screw 5, but are not limited to use screw 5, can also adopt other fixed form.
In a preferred embodiment, described fan fixed network 2 adopts stainless steel, and described blower tray 3 adopts plated steel sheet, and blower tray 3 adopts the plated steel sheet that hardness ratio is larger can effectively protect fan 1 and play the effect that limits flexure strip 23 overflexings.
Above an embodiment of the present utility model is had been described in detail, but the preferred embodiment that described content is only created for the utility model can not be considered to the practical range of creating for limiting the utility model.All equalization variation and improvement etc. of doing according to the utility model creation application range, within all should still belonging to patent covering scope of the present utility model.
