Embodiment 1

Present embodiments provide a kind of adjustable lamp stand, as shown in figure 1, including head 10, support bar 20 and Power Supply Assembly. Head 10 includes sleeve 11, reducing motor 12 and support 13, and sleeve 11 is in the tubular of the truncated cone-shaped that front end is big, rear end is little, sleeve 11 front end is uncovered, and the part that bulb is connected with lamp holder (is glass shell part for electric filament lamp, comes for electricity-saving lamp Say it is U-shaped fluorescent tube) can snap in sleeve 11.The output shaft of reducing motor 12 is connected with the rear-end transmission of sleeve 11, and slow down electricity Machine 12 is fixedly mounted on support 13, and support 13 is connected on support bar 20.Power Supply Assembly includes power supply 30 and converter, frequency conversion Device may be mounted on support 13, and power supply may be mounted in support bar 20.Power supply 30 passes through first switch 31 and converter Rotate forward terminal and reversion terminal connects, converter 38 is connected with reducing motor 12.

This device use when, the lower end of maintainer hand-held supports bar 20, reach appointed place after, find operation accurately and stand Point, then lifts support bar 20, adjustment position, makes sleeve 11 entangle bad bulb to be changed, then stirs first switch 31, make Power supply is connected with the reversion terminal of converter 38, so that reducing motor 12 band moving sleeve rotate counterclockwise, bulb is backed out, then Stir first switch 31, the connection of deenergization 30 and converter 38.Then put down support bar 20, by the bad bulb backed out from set Take out in cylinder 11, and the bulb put into, lift support bar 20, adjustment position, make bulb be directed at socket position, then stir first Switch 31, makes power supply be connected with the rotating forward terminal of converter 38, now sleeve turns clockwise, and bulb is tightened, and is then turned off Power supply, replacing bulb completes.Maintainer is when using this device bulb dismounting, if skidded between bulb and sleeve, permissible Sleeve is promoted slightly upward, increases the frictional force between bulb and sleeve 11.

Damage bulb in order to avoid the torque of reducing motor 12 output is excessive, in the present embodiment, power supply 30 selects 3.7 volts Rechargeable battery, the rotation dynamics very little of sleeve, after bulb is tightened, without deenergization, reducing motor will be automatically stopped rotation, And light fixture will not be caused with any damage.

In the present embodiment, between power supply 30 and converter 38, the first switch 31 of setting is single-pole double-throw switch (SPDT).As Fig. 2 Shown, one of first switch 31 not moved end be connected with the rotating forward terminal of converter 38 by the first electric wire 32, first switch 31 Another be not connected with the reversion terminal of converter 38 by the second electric wire 33 moved end, the first electric wire 32 is provided with the first finger Show lamp 35, the second electric wire 33 is provided with the second display lamp 36.In the present embodiment, the first display lamp 35 is blue bulb, second Display lamp 36 is white bulb.By arranging the first display lamp 35 and the second display lamp 36, maintainer can be made intuitively to see Examine the steering of reducing motor, it is to avoid maloperation.It is connected by the 3rd electric wire 34 between power supply 30 and the moved end of first switch 31, the Three second switches 37 are in series with three electric wires 34, are connected in parallel with each other between three second switches 37, three second switches 37 It is separately positioned at the differing heights of lower beam 22, to facilitate in the when open or closed power supply gripping support bar 20.

First switch in the present embodiment can also select two single-pole single-throw switch (SPST)s, one of single-pole single-throw switch (SPST) string It is associated on power supply and the electric wire rotating forward between terminal of converter 38, another single-pole single-throw switch (SPST) is connected on power supply and converter On electric wire between 38 reversion terminal.

In the present embodiment, Power Supply Assembly also includes bead 23, and bead 23 is using the wooden work that insulate.Support bar 20 includes Upper boom 21 and lower beam 22, the lower end of upper boom 21 is threadably secured the upper end being arranged on bead 23, the upper end of upper boom 21 with Frame 13 connects, and the upper end of lower beam 22 is threadably secured the lower end being arranged on bead 23, is spaced between upper boom 21 and lower beam 22 Bead 23, by arranging bead, plays earth leakage protective effect in operation, reaches the effect of safe insulation, energy Enough maintainer is effectively avoided to get an electric shock it is ensured that the personal safety of maintainer.

In order to adapt to the dismounting of the bulb on differing heights, the upper boom 21 in the present embodiment and lower beam 22 are telescopic rod. Upper boom 21 and lower beam 22 all can adopt plurality of sections of steel pipes, and the connected mode between two adjacent section steel pipes is：The less steel of diameter In the pipe steel pipe that is relatively large in diameter of insertion, then pass through bolt by two fastener for connection together, can be relatively large in diameter or less Steel pipe on open up multiple installing holes, multiple installing holes are evenly arranged along the axis of steel pipe, with reach control the less steel of diameter The length in steel pipe that pipe insertion is relatively large in diameter.Certainly, upper boom 21 and lower beam 22 can also be stretched automatically using of the prior art Contracting bar.

Sleeve 11 includes base plate 14 and at least two panels circular arc spring steel plate 15, and the rear end of every flat spring steel disc 15 is fixing even It is connected on base plate 14, constitute round table-like sleeve, be respectively provided with gap, gap between the neighboring edge of adjacent springs steel disc 15 two-by-two It is gradually increased from rear end to front end, in the present embodiment, the quantity of spring steel plate 15 is 3 pieces, and spring steel plate 15 adopts spring steel Make.By using spring steel plate 15, it can be avoided that sleeve produces the situation of abrasion deformation due to being used for multiple times.

For the ease of the angle between adjustment support 13 and upper boom 21, in the present embodiment, offer in the upper end of upper boom 21 Bolt hole, support 13 also offers bolt hole, is bolted between upper boom 21 and support 13.When need change support with During angle between upper boom, bolt can be unscrewed, then adjust the angle of the two, then bolt is tightened.

In the present embodiment, the output shaft of reducing motor 12 is connected with the rear end of sleeve 11 by universal joint.By using ten thousand Xiang Jie, can make the bulb entangling needs dismounting that sleeve is convenient.First display lamp 35 and the second instruction in the present embodiment Lamp 36 is all fixedly installed on reducing motor 12.

Described reducing motor includes motor body 1, casing 2, jackshaft 3, bearing block 4, cover plate and output shaft 5；

Described casing 2 is fixed on the housing of described motor body 1, and in the present embodiment, the middle part of described casing 2 is provided with Transverse slat 6, described casing 2 is divided into upper accommodation space and lower accommodation space, the rotary shaft of described motor body 1 by described transverse slat 6 On be coaxially installed with first gear 7, described first gear 7 be located at described lower accommodation space.

Second gear and the 3rd gear are coaxially installed with described jackshaft 3, described second gear is nibbled with first gear 7 Close, so that when described motor body 1 works, when that is, the rotary shaft of described motor body 1 rotates, described jackshaft 3 can be driven Rotate, in the present embodiment, the number of teeth of second gear is more than first gear 7, with when first gear 7 is driven to second gear, real Now slow down.

In the present embodiment, described second gear is located at described lower accommodation space, and described 3rd gear is located at described accommodating Space, the top and bottom of described jackshaft 3 are supported in upper wall and the lower wall of described casing respectively by deep groove ball bearing, described The middle part of jackshaft 3 is supported in described transverse slat 6 by deep groove ball bearing.
