Abstract

The utility model discloses a lamp bulb displacement unit, comprising a telescoping drawbar and a gripping mechanism for the head; the gripping mechanism comprises a base with a round hole arranged at the center; the circle at the outside of the round hole is provided with a plurality of shafts perpendicular to the base in a symmetry manner; each shaft is symmetrically encased with a clawed gear; each clawed gear is engaged with a sun gear; the sun gear shaft is positioned in the round hole of the base center; the center of the sun gear shaft is provided with a set groove; the head of the telescoping drawbar is positioned in the set groove; each shaft tip is provided with a top cover. With the utility model technical proposal, owing to the fact that the telescoping drawbar can be extended, the claw arm of the gripping mechanism at the head can chuck the lamp bulb at a high place, and the lamp bulb can be taken down by rotating, applicable for the change of the screw socket incandescent globe bulbs or cylindrical power saving fluorescent lamps. The utility model is widely used for positions of a fence or a corridor of the prison, a custodial institution, a pound, a factory and a mine, etc.

Description

The bulb displacer

Technical field

The utility model relates to a kind of bulb displacer that is used for more changing the bulb.

Background technology

If change the incandescent lamp or the electricity-saving lamp of eminence, and often need be by ladder, effort and dangerous.People design the device that much more changes the bulb for this reason, but do not find the technical scheme identical with the present invention as yet.

Summary of the invention

The purpose of this utility model provides a kind of bulb displacer that need not by any facility of climbing to a higher point.

For achieving the above object, the utility model adopts following technical scheme: a kind of bulb displacer, the gripping mechanism that comprises telescopic lever and its head, described gripping mechanism comprises that a center has the base of circular hole, the circular hole outside was arranged with a plurality of rotating shafts perpendicular to base plane in one week, finger gear of equal symmetrical suit in each rotating shaft, all be engaged with a central gear with each finger gear, sun gear shaft is positioned at the circular hole at base center, the axle center of sun gear shaft has holddown groove, the head of described telescopic lever is arranged in holddown groove, item lid of each roller end installing.

Rotating shaft on the described base plane has three, the circumference symmetric arrangement, the pawl arm circumference symmetric arrangement on each finger gear, the terminal cover of pawl arm rubber sleeve, the outer middle side part of described top cover is a concave ball shape, and it is the rubber blanket of concave ball shape that the top cover outside is with the middle part that conforms to its shape.

Described telescopic lever is the more piece sleeve structure, and each saves the junction and is provided with the locking pipe thread.

Adopt technical scheme described in the utility model, because telescopic lever can extension elongation, can make the bulb of the pawl arm chucking eminence of its head gripping mechanism, bulb is taken off in rotation then, is applicable to the incandescent globe bubble of screw-socket or the replacing of cylindrical power saving fluorescent lamps.Simple to operate, quick, each part adopts all-plastic design, and is non-conductive, safe and reliable, can be widely used in the enclosure wall that prison, detention house, the house of detention, factories and miness etc. locate, the replacing of crossing 3～6 meters eminence screw base lamps in corridor or power saving fluorescent lamps.

Embodiment

As shown in Figure 1, 2, the utility model comprises the gripping mechanism of telescopic lever 11 and its head, gripping mechanism comprises that a center has the disc base 8 of circular hole, the circular hole outside was provided with three rotating shafts 6 perpendicular to base 8 planar circumferential symmetric arrangement in one week, finger gear 5 of equal symmetrical suit in each rotating shaft 6, the pawl arm 3 circumference symmetric arrangement on each finger gear 5, pawl arm 3 terminal cover rubber sleeves 1, rubber sleeve 1 has elasticity, can provide big frictional force can not squeeze brokenly bulb glass again.All be engaged with a central gear 9 with each finger gear 5, the circular shaft 10 of central gear 9 is positioned at the circular hole at base 8 centers, the axle center of sun gear shaft 10 has cubic holddown groove 13, the head of telescopic lever 11 inserts in the holddown groove 13, telescopic lever 9 is two joint sleeve structures, two joint junctions are provided with locking pipe thread 12, and end is provided with the end of 15, three rotating shafts 6 of handle and fixes top cover 7 of installing with screw 4.Top cover 7 outer middle side parts are concave ball shape 14, and top cover 7 outsides are with the rubber blanket 2 that the middle part that conforms to its shape is a concave ball shape 14.

Rotary extension pull bar 11 is adjusted the position of each finger gear 5 dewclaw arm 3, pawl arm 3 is positioned on the extended line of circle center line connecting of the center of circle of central gear 9 and finger gear 5, the inner ring maximum that such three pawl arms 3 surround, telescopic lever 11 with two joint suits draws back and locks pipe thread 12 then, if length is not enough, all right suit is the more piece pull bar more, lift telescopic lever 11, the spherical glass that makes bulb is all around between three pawl arms 3, hold out against telescopic lever 11, the spherical glass bottom item of bulb is gone in concave ball shape 14 middle part of the rubber blanket 2 of lid 7 outside suits, and rubber blanket 2 has elasticity, can provide big frictional force can not squeeze brokenly bulb glass again.Hold out against bulb on one side, one side is rotary extension pull bar 11 left, central gear 9 drives three finger gears 5 simultaneously to right rotation, when the pawl arm 3 of three finger gears 5 tightens around the spherical glass of bulb simultaneously, continue rotary extension pull bar 11 left, it is left-handed and from screw-socket bulb is taken out that pawl arm 3 can drive bulbs.

If bulb is installed toward eminence, elder generation's rotary extension pull bar 11 is adjusted the position of each finger gear 5 dewclaw arm 3, the inner ring maximum that three pawl arms 3 are surrounded, place between three pawl arms 3 around the spherical glass with bulb, rotary extension pull bar 11 to the right then, central gear 9 drives three finger gears 5 simultaneously to anticlockwise, when the pawl arm 3 of three finger gears 5 tightens around the spherical glass of bulb simultaneously, lift telescopic lever 11, make the bulb screw aim at the screw-socket of eminence, continue rotary extension pull bar 11 to the right, pawl arm 3 can drive bulb dextrorotation goes in the screw-socket, after screwing, reverse rotary extension pull bar 11 left, pawl arm 3 can unclamp around the spherical glass, packs up telescopic lever 11 then, finishes the installation bulb that hoists.
