Abstract

A telescopic down lamp, which comprises a junction box (1), a lamp holder (13), a mounting bracket (4) and an outer ring (9), wherein no less than two connecting sheets (2) extending downwards are fixed on the lower part of the junction box. The utility model is characterized in that: a lamp barrel (6) opened at both ends is fixed on the outer ring; a lengthwise sliding chute (3) is opened on the side wall of the lamp barrel; the lengthwise sliding chute is staggered by a certain angle circumferentially from the fasteners (14) on the fixing bracket; the connecting sheets (2) are fixedly connected with the lamp barrel by an adjusting screw (5) that runs through the sliding chute. The lengthwise sliding chute of the utility model can be staggered circumferentially from other components, which can be extended downwards to increase the range of height adjustment for the down lamp.

Description

Telescopic Down lamp

Technical field

The utility model belongs to a kind of Down lamp.

Background technology

Down lamp is mainly by terminal box, lamp holder, reflection shield, fixed mount is formed with several parts of the outer shroud that is fixed on the lower openings place, by the outer shroud of end opening shade shape and the fixed mount on top lamp body is clipped on the furred ceiling during use, be fixed, because the distance between ceiling and the furred ceiling is different, so often need to regulate the height of lamp body when Down lamp is installed, the cylinder lamp structure of existing adjustment height is the brace that up terminal box bottom is provided with downward extension, a slab adjustment sheet with vertical chute is fixed on the outer shroud top of below, set screw is passed the adjustment sheet chute and is threaded with brace, the terminal box on top and the slab adjustment sheet of bottom are fastenedly connected, and can be by the height of set screw in the position adjustments terminal box of chute, its weak point is, with also the secure component that is connected with fixed mount to be set on the relatively-stationary slab adjustment sheet of outer shroud, vertically the bottom of chute can only be limited on these secure components, extend downwards thereby limited chute, make the adjustable extent of lamp body height less.

Summary of the invention

The technical problems to be solved in the utility model provides the big scalable Down lamp of a kind of height adjustment range.

The technical scheme that addresses the above problem is (referring to implementing illustration): the utility model comprises terminal box (1), lamp holder (13), the fixed mount (4) and the outer shroud (9) that are used for fixing lamp body, the terminal box bottom is fixed with and is no less than two braces (2) that extend downwards, it is characterized in that: the lamp tube (6) of a upper and lower opening is fixed on described outer shroud top, have chute (3) longitudinally on the lamp tube sidewall, vertically the secure component (14) on chute and the fixed mount is at the circumferential certain angle that staggers, each brace (2) bottom is equipped with set screw (5) respectively, and the chute (3) that set screw is passed the lamp tube is fastenedly connected brace and lamp tube.

Operation principle of the present utility model is: unclamp set screw (5), brace can be regulated the height of whole lamp body along the chute longitudinal sliding motion on the lamp tube, set screw is tightened after mixing up height, is about to brace and lamp tube and is fastenedly connected.

Vertical chute (3) that the utility model is regulated height is arranged on the lamp tube of annular, so just can make secure component on itself and the fixed mount in circumferential staggered positions, make vertical chute can extend downwardly into lamp tube bottom, increase the adjustable extent of Down lamp height, the utility model also can improve the mechanical strength of whole Down lamp simultaneously.

Specific embodiments

Lamp tube 6 under sheds and outer shroud 9 inner hole walls of this routine upper and lower opening are connected as a single entity, the lamp barrel is provided with vertical chute 3, the brace 2 of two 180 degree of being separated by is equipped with in terminal box 1 bottom, two braces extend into the lamp tube inner chamber by the jack on the lamp barrel 8, set screw 5 is passed lamp tube sidewall from the outside vertical chute 3 is connected with brace 2 lower thread, be provided with the anti-skidding protruding mound 12 of projection on the lamp tube inwall that is slidingly connected with brace 2, brace slides in the time of can preventing to regulate height.

This routine fixed mount 4 is a shell fragment, shell fragment is by secure component 14 and lamp tube 6 relative fixed, shell fragment and on secure component 14 and lamp tube on vertical chute 3 at circumferential 90 degree that stagger, clamp furred ceiling 7 with shell fragment and lamp tube lower cap along outer shroud 9 elasticity of formula, lamp tube 6 can be fixed on the furred ceiling.

When Down lamp is installed, tighten set screw, be about to brace and lamp tube and be fastenedly connected, unclamp set screw, can regulate the Down lamp whole height from the outside.

This example is provided with reflection shield 11 in the lamp tube.

The utility model also can not be provided with reflection shield in addition, directly utilizes the lamp tube to make reflection shield and coat reflecting coating at lamp tube inwall, makes its structure simpler.
