Description
Technical field
This utility model relates to technical field of communication equipment, is specifically a kind of double leval jib abat-vent.
Background technology
Along with the message capacity of communication equipment is increasing, power is also more and more higher, and in equipment component, the fan of monolayer cannot meet the radiating requirements of equipment, has therefore adopted the mode of two-layer fan superposition to meet the radiating requirements of equipment in the big equipment of part.As it is shown in figure 1, two superimposed fan: fan A and fan B, device interior (business panel) to dry to device external, cold wind enters from device bottom, takes away business panel heat, then is discharged by top.
But, in use can there is failure conditions in fan: when carrying out fan replacing or not high of equipment joined business dish power need to configure a fan unit, whole heat dissipation wind channel exists failure conditions.Such as, if fan B lost efficacy when needing replacing or fan B not to fit into equipment, fan B region forms a breach, whole air channel loses sealing, portion of external cold wind from former fan B location access arrangement, then through fan A remover apparatus top, can this greatly reduces the air quantity by business panel, cause losing efficacy in whole air channel, business dish as temperature is too high and cisco unity malfunction even burns.
For solving this problem, generally way is to design one piece of mobilizable baffle plate 1 in fan B region in the industry, and baffle plate 1 is fixed on sub-frame by the rotating shaft 2 with torsion spring.As in figure 2 it is shown, when fan B is not in place (when being not inserted into), baffle plate 1, under the effect of torsion spring, keeps vertical state, blocks air channel breach, it is ensured that do not lose efficacy in internal air channel.But this design has a disadvantage that: as it is shown on figure 3, when fan B is in place (when inserting), baffle plate 1 falls down, occupy part air channel, internal air channel there is is certain obstruction, reduces the heat-sinking capability in air channel.Under limiting case, if the height in fan B region is the same with the degree of depth, air channel will be blocked by baffle plate 1 completely that fall down, and existing design can not adopt in this case.

Detailed description of the invention
Below in conjunction with drawings and Examples, this utility model is described in further detail.
Shown in Figure 4, this utility model embodiment provides a kind of double leval jib abat-vent, and including base 3, base 3 includes the backboard 3b being vertically arranged, it is all vertical with backboard 3b that the side of backboard 3b is relatively set with left plate 3a and right plate 3c, left plate 3a, right plate 3c；Left plate 3a, right plate 3c inner side be respectively hinged with two connecting rods, each connecting rod can around place side plate 180 ° rotation.It is vertically arranged with at least one deep bead 8 between two connecting rods and two connecting rods of right plate 3c of left plate 3a, the left side of each deep bead 8 is connected with two connecting rods of left plate 3a respectively, and the right edge of each deep bead 8 is connected with two connecting rods of right plate 3c respectively.Described left plate 3a, two connecting rods of left plate 3a and the left side of deep bead 8 collectively constitute the quadric chain of parallelogram；Described right plate 3c, two connecting rods of right plate 3c and the right edge of deep bead 8 collectively constitute the quadric chain of parallelogram.In the present embodiment, the quantity of described deep bead 8 is two, form pair of pages double leval jib abat-vent, when actual production uses, according to the height in fan B region, by increasing the length of (or shortening) connecting rod, the quantity of (or minimizing) deep bead 8 can be increased accordingly, it is designed to the double leval jib abat-vent of multipage or single page, applied widely；And two connecting rods of two connecting rods of deep bead 8, left plate 3a, right plate 3c and biside plate (left plate 3a, right plate 3c) all adopt rigid material to make, it is possible to the quadric chain that composition is firm.
Shown in Figure 5, when all deep beads 8 turn to the surface of backboard 3b under the drive of connecting rod, between adjacent deep bead 8, adjacent mutually between deep bead 8 and backboard 3b, do not interspace (formation shutter), this device so can be made effectively to block air channel breach in use, it is ensured that the sealing in internal air channel.Shown in Figure 6, owing to deep bead 8, connecting rod and side plate collectively constitute the quadric chain of parallelogram, therefore, no matter connecting rod is around which kind of angle place side plate turns to, all deep beads 8 all remain vertical state, namely with backboard 3b keeping parallelism, deep bead 8 so can be made parallel with the wind direction in air channel all the time, air channel will not be hindered, it is ensured that the heat-sinking capability in air channel.
Specifically, two connecting rods of left plate 3a are left side first connecting rod 4 and left side second connecting rod 7 respectively, and two connecting rods of right plate 3c are right side first connecting rod 9 and right side second connecting rod 10 respectively；The left side of each deep bead 8 is connected with left side first connecting rod 4 by the first movable axis 5, is connected with left side second connecting rod 7 by the second movable axis 6；Equally, the right edge of each deep bead 8 is connected with right side first connecting rod 9 by the first movable axis 5, is connected with right side second connecting rod 10 by the second movable axis 6；It addition, left side first connecting rod 4, right side first connecting rod 9 are respectively hinged with place side plate by the first jointed shaft 12, left side second connecting rod 7, right side second connecting rod 10 are respectively hinged with place side plate by the second jointed shaft 13.On this basis, in order to ensure that quadric chain is a parallelogram sturcutre (all deep beads 8 of such guarantee are in plumbness all the time), the distance between distance=the first jointed shaft 12 and the second jointed shaft 13 between described first movable axis 5 and the second movable axis 6.
Further, referring to shown in Fig. 4 to Fig. 6, in order to make this device not by under External Force Acting, normally off can be kept (namely to keep deep bead 8 to be positioned at the surface of backboard 3b, make between adjacent deep bead 8, mutually adjacent between deep bead 8 and backboard 3b, do not interspace), it is provided with spring 11 between left side first connecting rod 4 and left side second connecting rod 7, between right side first connecting rod 9 and right side second connecting rod 10, the two ends of each spring 11 are each affixed with a connecting rod.
Shown in Figure 7, this utility model double leval jib abat-vent is installed on the installing port place of fan B, when fan B is not in place (when fan B is not inserted into), all connecting rods are under the active force of spring 11, keep Fig. 7 state so that between adjacent deep bead 8, mutually adjacent between deep bead 8 and backboard 3b, do not interspace, can effectively block air channel breach, it is ensured that the sealing in internal air channel.When fan B inserts, fan B extrudes link rotatable, and drives deep bead 8 to rotate down.After fan B is fully-inserted (when namely fan B is in place), shown in Figure 8, deep bead 8 is positioned at the side of backboard 3b, and deep bead 8 still keeps vertical state, parallel with wind direction in air channel, on air channel without impact, it is ensured that the heat-sinking capability in air channel.
This utility model is not limited to above-mentioned preferred forms; anyone can draw other various forms of products under enlightenment of the present utility model; no matter but in its shape or structure, do any change; every have same or like with this utility model like technical scheme, all within its protection domain.
