Description

The height adjuster of electric fan

The utility model system provides a kind of height adjuster of electric fan, relates to electric fan.

The height adjustment structure of electric fan is shown in first figure now, lie in an electric fan base 10 substantially and extend upwardly the body of rod 30 of planting in the column casing of establishing 20,301 of the top breach of the body of rod 30 are assembled electric fan head (comprising members such as motor, flabellum and guard) according to this, be screwed into the barrel mast 20 and then the packing location body of rod 30 with a bolting element 40 again, by bolting element 40 move back the lock or lock and adjusted the body of rod 30 lifting heights, this kind height adjustment structure has following disappearance at least on manipulating:

One. adjust height each time, promptly will rotate bolting element and withdraw from, choose height after, the precession bolting element 40 again, the so frequent bolting element 40 that rotates very is to waste time and energy and bother.

Two. because the body of rod 30 is assembled with the electric fan head, weight increases and the gravity of decline is arranged, and adjusts the body of rod 30 suitably during height, must help the body of rod 30 to prevent to descend on the other hand, and then just can rotate bolting element 40, inconvenience during operating cost by another hand.

The purpose of this utility model provides a kind of only need and releasing back by finger presses can reach the device of adjusting the electric fan height rapidly.

The utility model is to realize like this, regulating device, at least include: comprising: the electric fan base, it is characterized in that base is up stretched is provided with a hollow column casing, hollow column casing inner bottom is equipped with first elastic element, and the top is connected with a ring set, and ring set inside has a riser and a putting chamber, inner edge surface is provided with a protruding rail, and outer edge surface is provided with the open-work that connects mutually with putting chamber; Have one by press button in the ring set putting chamber, have a protruding button by press button top one side, protruding button madial wall is established a shrinkage pool, and is connected to the riser of shrinkage pool and ring set respectively with the two ends of one second elastic element, protruding button is protruding to be placed outside the open-work, extends a grab that stretches into hollow column casing inside by the bottom of press button; First elastic element top have a flexible rod, flexible rod outer edge surface be provided with one with the strip guide groove of the corresponding coupling of ring set protruding rail, this strip guide groove inside is provided with the equidistant grab selection for by press button of plural number and engages the blocking groove of locating.

Wherein, the set equidistant blocking groove of the plural number system of flexible rod presents shallow dark squint shape down.

Wherein, the set strip guide groove upper end of flexible rod has a location slotted eye, and is provided with a positioning block in abutting connection with the flexible rod shaft on strip guide groove top, and in order to do when flexible rod drops to the end, positioning block supports due to the ring set rim surface, and the proper fastening of grab is in location notch hole.

The utility model with said structure has following practical effect:

One. only need to release the work that reverses again by belling button 41, can reach the purpose of whole flexible rod 6 height by what point, very simple and easy laborsaving and quick.

Two. flexible rod 6 is because of the permanent state that keeps desire to rise of the support that is subjected to first elastic element 2, can help to hold flexible rod 6 and can adjust height, convenient few power.

The following drawings and this are executed example and will be described further technical characteristics of the present utility model:

Fig. 1 is the stereogram of existing device.

Fig. 2 is a three-dimensional exploded view of the present utility model.

Fig. 3 is a combination section of the present utility model.

Fig. 4 is that illustration is highly implemented in adjustment of the present utility model.

Fig. 5 is the part amplification profile action diagram of Fig. 4 of the present utility model.

Embodiment:

The utility model comprises shown in Fig. 2,3: electric fan base 1, and it up stretches the hollow column casing of establishing 11, and the inner bottom of this hollow column casing 11 is put first elastic element 2; One ring set 3, firmly steady by the ground gluing in hollow column casing 11 tops, the outer edge surface of this ring set 3 is established an open-work 31, inside has a riser 32 and a putting chamber 33, inner edge surface is then established with a protruding rail 34, open-work 31 also connects (as shown in Figure 5) mutually with putting chamber 33; One presses press button 4, top one side has a protruding button 41, the madial wall of protruding button 41 is established a shrinkage pool 411, should then extend a grab 42 by the bottom of press button 4, going into by 4 groups of press buttons in the putting chamber 33 of ring set 3, the two ends with second elastic element 5 are connected to riser 32 and shrinkage pool 411 respectively again, are subjected to the elastic force effect of second elastic element 5 and are resisted against ring card 3 inner edge surfaces by press button 4, and protruding button 41 and prominent being arranged at outside the open-work 31, grab 42 also stretches into hollow column casing 11 inside (as shown in Figure 5); One to stretch sanctified by usage be bar 6, system carries over the protruding rail 34 that cooperates ring set 3 and organizes in the void column tube 11 downwards with the set back of its outer specific surface bar guide groove 61, first elastic element 2 is just upwards accepted flexible rod 6 bottoms, flexible rod 6 top breach 2 then can be installed interlocking electric fan head and (comprise motor, member such as flabellum and guard), aforementioned strip guide groove 61 inside then are provided with the equidistant clip groove 611 of plural number and the location notch hole 612 of upper end, this clip groove 611 is the squint shape that is dark on the supernatant and can cooperates with grab 42 clips, and in abutting connection with the flexible rod 6 shafts system on strip guide groove 61 tops a positioning block 63 is set.

The utility model is operated when implementing such as Fig. 4, shown in 5, the elastic reaction of first elastic element 2 is in flexible rod 6 bottoms, make the rise that keeps up of flexible rod 6 perseverances, because of location flexible rod 6 states are formed on the bottom of a certain clip groove 611 of being fastened in of grab 42, in case press the top of belling button 41, be to be center and a certain angle of rotation then with second elastic element 5 by press button 4, the grab 42 of this moment leaves clip groove 611 bottoms of original engaging, make flexible rod 6 not be subjected to clip and rise, in case allay strength by belling button 41, then second elastic element 5 impels immediately by press button 4 returning positions, and make grab 42 be sticked in the bottom of a certain clip groove 611 once again, so that flexible rod 6 can be made Height Adjustment together with the electric fan head.

When desiring to make flexible rod to reduce to extreme lower position, must press protruding button 41 tops earlier, make grab 42 leave a certain clip groove 611 bottoms, depress flexible rod 6 again to overcome the elastic force of first elastic element 2, when flexible rod 6 was depressed to the end, positioning block 63 just supported due to ring set 3 rim surface, then allays the strength by belling button 41 this moment, grab 42 be return and fastening immediately in location notch hole 612, the certain positioning states when forming flexible rod 6 and reducing to extreme lower position.
