In as the described circuit of this embodiment, discharge cock 21 comprises a normal open switch of establishing for the power line between socket 44 to second terminal 32, as shown in figure 15.
Below introduce the installation method of pillar 4 on pedestal 3.When the supporting portion 25 of pillar 4 inserted in the pillar supporting part 10, locating bump 13 can embed in the positioning groove 33.In this grafting action, because positioning groove 33 and locating bump 13 embedding mutually, supporting portion 25 can not rotate, thereby can not dock the phenomenon that line end 23,32 is exerted pressure and made it to damage.
When the supporting portion 25 of pillar 4 was completely enclosed in the pillar supporting part 10 of pedestal 3, the connection pawl 34 on supporting portion 25 column bases 26 can engage with the bottom surface of pillar supporting part 10, thereby pedestal 3 and pillar 4 are tightened up provisionally.When screwing assembling fixing units 35, need make pillar 4 and together counterrotating of pedestal 3.Because pedestal 3 is tightened up temporarily, therefore only need hold pillar 4 and just can finish the counter-rotating action, this measure also can avoid pedestal 3 to come off in Umklapp process.So above-mentioned processing has better assembly process process.
To the pedestal 3 that temporarily tightens up and pillar 4 in addition counterrotating and fixed element 35 is screwed in the helical thread portion 27 of supporting portions 25 after, pedestal 3 and pillar 4 are just by affixed good.The element 35 that continues to be tightened will make the action part 22 of discharge cock 21 be subjected to the compressing of fixed element 35, thereby makes power supply via in terminal 23, the 32 input motors, has so just finished the assembling of pedestal 3 with pillar 4.
The fixed element 35 that is threaded into faces the card of the periphery and the supporting portion 25 of pillar supporting part 10, so pillar supporting part 10 can be tightened up reliably with supporting portion 25, and pillar 4 can be contained on the pedestal 3 with being stabilized and do not rock simultaneously.The screw thread of fixed element is to go into from base bottom surface one sidespin via a through hole on the pillar supporting part in the ordinary construction, in contrast to this, the way that screws in fixed element 35 in supporting portion 25 outer rims will increase the screwed joint area between supporting portion 25 and the fixed element 35, thereby can strengthen the bearing strength of pillar 4, thereby make pillar 4 stably by base support.
When the circular rib 30 at supporting portion 25 tops embeds pillar supporting part 10 apical margin grooves 11, the anastomosis part 31 of supporting portion 25 bottoms also can embed in the groove 12 of pillar supporting part 10 lower edges, therefore, be subjected to the groove outward force at pillar 4 and do the time spent, even fixed element 35 is not threaded into or is not screwed fully, the conjugation between circular rib 30 and groove 11 and anastomosis part 31 and the groove 12 can guarantee that also pillar 4 supports with being stabilized.
When pedestal 3 is unexpectedly trampled, the periphery of pillar supporting part 10 is easy to take place the radial deformation along side direction in it, but in the present invention, because the anastomosis part 31 of supporting portion 25 embeds in the groove 12 of pillar supporting part 10 bottoms, the riser 24 of crown cap 9 also embeds in the engaging groove 14 simultaneously, therefore the intensity of pillar supporting part 10 is improved, and has so just avoided the distortion of pillar supporting part 10 peripheries.
If the annular flange flange of pillar 4 29 is unexpectedly trampled, it will be easy to take place bending deflection upwards, but in the present invention, because the circular rib 30 of supporting portion 25 embeds in the groove 11 of pillar supporting part 10 upper limbs, and the anastomosis part 31 of supporting portion 25 also embeds in the lower edge of pillar supporting part 10, so the intensity of pillar 4 bottoms is improved, therefore the distortion of pillar 4 is also avoided.
In addition, the startup effect of 35 pairs of discharge cocks 21 of fixed element is to be loaded in the pedestal 3 and fixed element 35 just takes place when being threaded in the supporting portion 25 of pillar 4 at pillar 4.In other words, discharge cock 21 is only reliably tightened up Shi Caihui at pedestal 3 and pillar 4 and is started, therefore, if when pillar 4 and pedestal are separated, touch first terminal 23 because of carelessness, even power line is inserted on the socket and also can not be shocked by electricity so.In addition, be not installed as yet at fixed element and make under the condition that pillar 4 plays pendulum, above-mentioned measure can guarantee that electric fan can't connect electric operation, so just further guarantees its Security.
The action part 22 of discharge cock 21 is positioned at more than the bottom of pedestal 3 peripheries, therefore, even pedestal 3 drops on the table top of floor one class under the situation of removing fixed element 35, the action part 22 of discharge cock 21 can not started by floor and so on table top yet, so is avoided effectively on the electric shock incident.
In the above-described embodiments, discharge cock 21 only is located on the single line of power line between socket 44 to first terminal 23, in fact, all discharge cock can be set on two power lines between socket 44 to first terminal 23, as shown in figure 16.Under the condition that a certain power line interrupts, if the user touches certain contact that links to each other with another root power line under ground state, leaky will very easily take place so, so the line construction design should guarantee that first terminal 23 are difficult for being switched on.And in two all interruptable present embodiments of power line, the structural type of first terminal, 23 parts of taking for preventing to leak electricity is simplified.
Represented a kind of structural type that all disconnects about two power lines among Figure 17 and Figure 18, wherein, be provided with a double-contact discharge cock 21 that has normally opened contact on the double joint power line, and the action part 22 of discharge cock 21 is driven by fixed element 35.Because single discharge cock 21 can interrupt two power lines, so this structure is more simple.
In Figure 19, all be provided with discharge cock 21,21 on the every power line, all should be fixed element 35 of the action part 22,22 of each discharge cock 21,21 drives for this reason.In this structure, discharge cock 21,21 can recommend to take form respect to one another on about 180 ° of orientation in the position on the pillar supporting part 10.Compare with the scheme that adopts single discharge cock 21, in the structure that adopts two discharge cocks 21,21, discharge cock 21, the restoring force of 21 action parts 22,22 can cause a bigger active force, and the direction of this active force is the direction that fixed element 35 and pillar 4 are separated just.Therefore, if discharge cock 21,21 is biased in a certain side of pillar supporting part 10, the restoring force of discharge cock 21,22 action parts 22,22 will act on and make on the direction that fixed element 35 prizes so, thereby bring the problem of fixed element 35 operability differences.And for discharge cock 21,21 on about 180 ° of orientation structure opposite each other, discharge cock 21,22 action parts 22,22 restoring force is not to act on prejudicially on the fixed element 35, so the operating characteristics of fixed element 35 is not weakened.
In the above-described embodiments, fixed element 35 is to be threaded into and to be fixed tightly on the supporting portion 25 of pillar 4, but in Figure 20 to Figure 22, the side of supporting portion 25 roughly relative position is provided with the protuberance 45 that is similar to cylinder, fixed element 35 internal surfaces also are provided with approximate L shaped connecting groove 46 simultaneously, and the protuberance 45 on the supporting portion 25 can embed in this connecting groove 46.The assembly method of fixed element 35 is in this structure: embed under the condition of connecting groove 46 at protuberance 45, fixed element 35 is moved axially at pillar along connecting groove 46, along connecting groove 46 rotational fixation elements 35, cross until protuberance 45 till the locking flange 47 of connecting groove 46 ends then.Finish after this fit, fixed element 35 is being oppressed the action part 22 of discharge cock 21, thereby has realized the connection of first terminal, 23 power supplys.
Shown in Figure 21 and 22, the mode that can recommend to take to make the horizontal component of connecting groove 46 to tilt, inclined degree is adjacent to pedestal with protuberance 45 fixed element 35 when terminal and exceeds, and like this, pedestal 3 can obtain firm tightening up by the rotation of fixed element 35 with pillar 4.
Compare with previous embodiment, in this structure, adorn, the spinning movement when tearing fixed element 35 open is comparatively simple, therefore install and remove operability and be improved.
In addition, the supporting portion 25 of pillar 4 and fixed element 35 also can take Figure 23 to structure shown in Figure 25.That is, in the side of supporting portion 25 groove opposite 48 is set, simultaneously fixed element 35 also is made into oblateness, and that its inner surface is provided with is 35 that vertically distribute along fixed element, can be plugged on the connection rib 49 in the groove 48.
As Figure 23 and shown in Figure 25, the supporting portion 25 in this structure is to insert wherein from an end of fixed element 35 no connection ribs 49, and the movement direction of fixed element 35 is shown in arrow among Figure 23, and connection rib 49 is with in mode embedding eight grooves 48 shown in Figure 24.Connection rib 49 tilts as follows: the closer to end then more near pedestal 3, and the inclination mode of groove 48 also tool on the grafting direction of connection rib 49, be adjacent to the characteristics of pedestal 3 gradually, therefore, fixed element 35 by its slide just can make pedestal 3 and pillar 4 mutually near and tighten up.Be respectively equipped with corresponding protruding 50, recess 51 on groove 48 and the connection rib 49, when connection rib 49 embeds in the grooves 48, above-mentioned protruding, recess 50,51 interlocks mutually, so fixed element 35 can not come off.
After fixed element 35 installed, it just drove discharge cock 21 and leads to the electric current of first terminal 23 with connection, as shown in figure 24.
In the various embodiments described above, the supporting portion 25 of pillar 4 is to stretch to its bottom surface one side from the pillar supporting part 10 of pedestal 3, and the supporting portion 25 that fixed element 35 then will stretch out pedestal 3 bottom surfaces tightens up, thereby pedestal 3 and pillar 4 are fused.But Figure 26 and embodiment illustrated in fig. 27 what take is another kind of structure: the fixed element 53 of threaded 53a is threaded into again in the bottom surface of supporting portion 25 passing out behind the through hole 52 of pillar supporting part 10 bottom surfaces, thereby pillar 4 and pedestal are tightened up, and fixed element 53 is also oppressed discharge cock 21 and is made it to start when pedestal 3 and pillar 4 are tightened up.
