Description

Adjustable ceiling lamp holder

Technical field

The utility model relates to the pendent lamp fixture, refers to a kind of adjustable ceiling lamp holder that can conveniently adjust suspension type light fixture height especially.

Background technology

The pendent lamp of general installing ceiling below is the top that an end of steel cable is fixed on pendent lamp, and the other end is fixed on the below of ceiling, thereby pendent lamp is suspended in the below of ceiling.

Yet, after this pendent lamp is contained in the ceiling below,,, must cut short, or change this steel cable into length long steel cable in order to the steel cable of hanging pendent lamp if will adjust the height of pendent lamp because the length of this steel cable is regular length after installing; Therefore, quite bother inconvenience if will adjust the height of pendent lamp, even must water detection electrician people come to revise in to the home, cause user's inconvenience and trouble.

Summary of the invention

The utility model aims to provide a kind of adjustable ceiling lamp holder that can conveniently adjust suspension type light fixture height for overcoming above-mentioned shortcoming.

The technical solution of the utility model is as follows: a kind of adjustable ceiling lamp holder comprises: cylinder base, bottom, central tube and lifting rope, and wherein: the cylinder base below is provided with a screw, and this screw is communicated with the side opening that is positioned at the cylinder base side, and this cylinder base is fixed in the ceiling below; The bottom top is provided with an external screw thread and an internal taper hole, and bottom is solid in the screw of cylinder base bottom by this external screw thread spiral shell; Central tube is installed in the internal taper hole of bottom, and this central tube top loop is provided with a plurality of perforation, should be incorporated with a steel ball in each perforation, and steel ball leans on the internal taper hole conical surface of bottom, is equiped with a spring between the screw end face of central tube top and cylinder base; Lifting rope is located in the central tube, and is passed by the side opening of cylinder base, each steel ball roof pressure lifting rope in the above-mentioned central tube, and a light fixture is hung in this lifting rope bottom.

The outside, above-mentioned central tube bottom is provided with a groove.

According to above-mentioned structure, the utility model can conveniently be adjusted the height of suspension type light fixture, and is easy and simple to handle, time saving and energy saving.

The specific embodiment

Referring to Fig. 1, a kind of adjustable ceiling lamp holder comprises cylinder base 1, bottom 2, central tube 3 and lifting rope 6.

Wherein, referring to Fig. 2,3, cylinder base 1 below is provided with a screw 11, and this screw 11 is communicated with the side opening 12 that is positioned at cylinder base 1 side, and this cylinder base 1 is fixed in the ceiling below.

Bottom 2 tops are provided with an external screw thread 21 and an internal taper hole 22, and this bottom 2 can be installed in the screw 11 of cylinder base 1 bottom by external screw thread 21.

Central tube 3 is installed in the internal taper hole 22 of bottom 2, these central tube 3 top loop are provided with a plurality of perforation 31, in this steel ball 4 of packing in 31 of respectively boring a hole, this steel ball 4 leans on the conical surface of the internal taper hole 22 of bottom 2, be equiped with a spring 5 between screw 11 end faces of these central tube 3 tops and cylinder base 1, central tube bottom outer rim is provided with a groove 32.

Referring to Fig. 3,4, lifting rope 6 is located in the central tube 3, and is passed by the side opening 12 of cylinder base 1, and each steel ball 4 roof pressures in the above-mentioned central tube 3 are on lifting rope 6, and a light fixture 7 can be hung in these lifting rope 6 bottoms.

Referring to Fig. 5, according to above-mentioned structure, cylinder base 1 can be fixed on the ceiling below, light fixture 7 is then hung in these lifting rope 6 bottoms.If in the time of will adjusting the height of light fixture 7, can push the central tube 3 that is positioned at cylinder base 1 bottom, central tube 3 bottom outer rims are provided with a groove 32, the external diameter of this groove 32 is less, help easily central tube 3 inwardly being pushed away, in these central tube 3 retraction cylinder bases 1, being installed in steel balls 4 in central tube 3 perforation 31 this moment does not lean on the conical surface of the internal taper hole 22 of bottom 2, make this steel ball 4 be lax state, therefore also roof pressure lifting rope 6 not simultaneously of this steel ball 4, the pull lifting rope 6 so up or down, to adjust the high and low position of light fixture 7.

If when adjusting upward light fixture 7 height, the pull that can directly make progress is exposed at the lifting rope 6 of side opening 12 outsides of cylinder base 1, make light fixture 7 adjust upward height; Otherwise, when adjusting the height of light fixture 7 downwards, pushing central tube 3, deadweight by light fixture 7 makes lifting rope 6 get final product to lower slider, above-mentioned groove 32 also helps to grip central tube 3, but be noted that preferably to haul lifting rope 6 tops simultaneously, and slowly put down lifting rope 6 and meet accident to prevent the moment landing.

When light fixture 7 is adjusted to suitable height, can decontrol central tube 3, this central tube 3 is protruding automatically by the ejection that is installed in its top spring 5, the perforation 31 interior steel balls 4 that are installed in central tube 3 this moment can lean against on the internal taper hole 22 of bottom 2, because the hole shape that internal taper hole 22 is big up and small down, so the more down past more central term of this steel ball 4 leans on, like this, can make steel ball 4 roof pressure lifting ropes 6, thereby can clamp lifting rope 6 simultaneously to be fixed by a plurality of steel balls 4, as shown in Figure 3, and pull down lifting rope 6 by the deadweight of light fixture 7, make lifting rope 6 tightly to be clamped, avoid producing landing by steel ball 4.
