Embodiment
Below in conjunction with accompanying drawing, the utility model is described in further detail. Wherein identical component represent with identical Reference numeral. It should be noted that, the nouns of locality such as the word "front", "rear" of use, "left", "right", "up" and "down" being described below and only refers to the direction in accompanying drawing, word " interior " and " outward " refer to the direction towards or away from particular elements geometric centre respectively.
A kind of high-tension switch cabinet; include cabinet 1 to form; on cabinet 1, wherein offered an air draft mouth 11; air draft mouth 11 is provided with exhaust fan 12; being embedded multiple ball 123 that can roll respectively on two end faces up and down of exhaust fan 12, ball 123 is arranged along the length direction of end face; Structure as shown in figure 3 or 4. Simultaneously, cabinet 1 is respectively arranged with the guide rail 13 for the exhaust fan 12 that slides relative to the two of exhaust fan 12 top side location, the guide path 131 also offered on guide rail 13 and guide ball 123 to slide, is also provided with the locking gear for exhaust fan 12 and cabinet 1 mutually being locked on cabinet 1.
When dismounting exhaust fan 12, drive in the guide path 131 of the ball 123 of exhaust fan about 12 two end faces on guide rail 13 by promoting exhaust fan 12 and roll, the dismounting of exhaust fan 12 can be realized, owing to adopting ball 123 tourelle, greatly reduce the frictional force between exhaust fan 12 and guide rail 13 so that dismounting all has effect fast and easily; Meanwhile, the rolling of ball 123 makes exhaust fan 12 be separated with air draft mouth 11, it is possible to the setting making people observe in cabinet by air draft mouth 11 very clearly, reaches the bonus effect that can observe plant and instrument working order in switching cabinet easily.
In addition, owing to being provided with locking gear so that exhaust fan 12 can very firmly be arranged on cabinet 1, the effect facilitating transport and using is reached.
In addition, in the side of exhaust fan 12 air draft, a push-pull rod that can dismount 121 is installed. Structure as shown in Figure 1. By the setting of push-pull rod 121, be equivalent to add an exhaust fan 12 by force, people are made to force in exhaust fan 12 easily when promoting exhaust fan 12, thus reaching the effect promoting exhaust fan 12 so that the dismounting of exhaust fan 12 and the process of observation cabinet 1 interior instrument equipment are more convenient.
Wherein, above-mentioned push-pull rod 121 can be arranged by this kind and realize: in edge two grafting holes, exhaust fan 12 side, push-pull rod 121 is inserted in grafting hole. Structure as shown in Figure 1. Arranged by this kind, when exhaust fan 12 dismantled by needs, only need to push-pull rod 121 be inserted in grafting hole, namely promote movement and the dismounting of exhaust fan 12 by push-pull rod 121, reach and push-pull rod 121 is dismantled fast, eliminate the impact owing to exhaust fan 12 is dismounted by push-pull rod 121.
As for the locking gear of exhaust fan 12, can be realized by following arranging: the side in exhaust fan 12 air draft has offered lock hole 124, cabinet 1 is also provided with guiding hole 125, wherein, guiding hole 125 is corresponding with installing lock hole 124 position after exhaust fan 12, and direction is also consistent. Also being combined with lock lever 14 in guiding hole 125, this lock lever 14 can insert and realize linking of guiding hole 125 and lock hole 124 in lock hole 124, thus reaches the locking effect of exhaust fan 12 and cabinet 1. Lock lever 14 is also arranged with stage clip 127, this stage clip 127 is the state being in compression all the time, stage clip 127 is fixedly connected on lock lever 14 near one end of lock hole 124, the other end is connected to the one side of cabinet 1 away from lock hole 124, also offering, in guiding inside, hole 125, the container cavity 128 placing stage clip 127, wherein container cavity 128 is interconnected with guiding hole 125. Like this, lock lever 14 stage clip 127 thrust under slide into lock hole 124 along guiding hole 125, form one for locking cabinet 1 latch-up structure with exhaust fan 12 with stage clip 127, lock hole 124. Structure as shown in Figure 5,6.
By above setting, after exhaust fan 12 installs, namely by under the lead constraint in hole 125 and guide effect, make lock lever 14 can only slip in lock hole 124 along the direction of lock hole 124, now, lock lever 14 just can stop exhaust fan 12 and cabinet 1 in the slip being perpendicular to lock lever 14 direction, reaches the effect of fixing exhaust fan 12 on cabinet 1.
Simultaneously, lock lever 14 has been nested with the stage clip 127 being in compressed state all the time, the stage clip 127 of compression has the reverse elastic force of a compression, by the tie point of stage clip 127 with lock lever 14, elastic force is passed to lock lever 14, reaches the effect promoting lock lever 14 to slide to lock hole 124.
In order to make people dismantle exhaust fan 12 easily, by lock lever 14 away from the end of lock hole 124 by being bent to form pull bar 141. Structure as shown in Figure 5,6. By this pull bar 141, when people need to stir lock lever 14, directly stir pull bar 141 and can very easily lock lever 14 be applied a pulling force, improve the efficiency of dismounting exhaust fan 12 greatly.
In order to convenient stirs lock lever 14, it is possible to the angle between lock lever 14 and pull bar 141 is set to 90 degree. Structure as shown in Figure 5,6. 90 degree of settings of pull bar 141 and lock lever 14 so that people are at the pull bar 141 times of equal length, it may be possible to provide bigger drag torque, thus reach the effect extracted by lock lever 14 making people lighter.
In the process of locking, lock lever 14 always could be inserted lock hole 124 through container cavity 128. Therefore, offered scarp 151 at container cavity 128 near one end of lock hole 124. Structure as shown in Figure 6. Lock lever 14 by the setting on scarp 151, is equivalent to increase the aperture of container cavity 128 end, serves the effect of guiding, even if still can pass container cavity 128 smoothly in the process of locking.
Insert at lock lever 14 and the process of lock hole 124 is still so, offered fillet structure 16 at lock hole 124 near the end in guiding hole 125. Structure as shown in Figure 6. This fillet structure 16 is also equivalent to increase the aperture of lock hole 124 while having guide effect, even if lock lever 14 tilts in the process of insertion lock hole 124, still by fillet, lock lever 14 inserts lock hole 124 smoothly.
It is last it is noted that above embodiment is only to explanation of the present utility model; it is not to restriction of the present utility model; the present embodiment can be made the amendment not having creative contribution as required by those skilled in the art after reading this specification sheets, but as long as being all subject to the protection of patent law in right of the present utility model.
