Embodiment
The utility model provides a kind of lamp installation shell fragment, to make the purpose of this utility model, technical scheme and effect more
Add it is clear, clear and definite, the embodiment that develops simultaneously referring to the drawings to the utility model be further described.It should be appreciated that this place
The specific embodiment of description only to explain the utility model, is not used to limit the utility model.
Fig. 1-6, a kind of lamp installation shell fragment, including the substrate 1 being fixed in lamp outer are referred to, passes through the first bending
The first elastic arm 2 that portion 21 is connected with the lower end of substrate 1, extended obliquely, and the extended on the substrate 1, obliquely is set
Two elastic arms 3；The place of the second elastic arm of face 3 offers the elongated hole that second elastic arm of confession 3 passes on first elastic arm 2
22, the width of the elongated hole is more than the width of the second elastic arm.
The two or more mounting elastic sheets can be equably installed along the circumference of lamp outer as needed during use, with Fig. 5
Exemplified by, two mounting elastic sheets are symmetrically installed, when light fixture 90 injects the mounting hole of ceiling, the first elastic arm is pressurized toward inner side
（In the application, inner side is directed to the side of light fixture, and outside is backwards to the side of light fixture）Shrink, the second elastic arm is worn at elongated hole
Going out and extruded by ceiling, it is bigger that the first elastic arm and the second elastic arm are squeezed frictional force simultaneously, and due to second
Elastic arm extends obliquely, and its end contacts with ceiling, and frictional force thereon can have the second elastic arm to open outward
Trend reaches self-locking effect so as to further increase frictional force, therefore effectively can prevent light fixture from sliding, safe.It is preferred that
, the angle between the first elastic arm 2 and substrate 1 is 30 °, and after both having can guarantee that lamp installation was complete, the first elastic arm has enough
Elastic force, and can ensure the first bending part 21 at stress will not be excessive.
Further, Fig. 1-5 are seen, the tail end of first elastic arm 2 is vertically arranged the lacing film 23 to extend outwardly.When
When light fixture descends for some reason, lacing film can catch on ceiling, prevent light fixture from falling, and further enhance security.
Preferably, Fig. 1-5 are seen, second elastic arm 3 is connected by the second bending part 31 with substrate 1.Specifically, second
The angle of bending part and substrate is 55 °, and the second bending part is 15 ° with the angle with substrate, when ensure that the second elastic arm is pressurized,
The Root Stress of second bending part will not be excessive.
In the present embodiment, Fig. 3 is seen, the tail end of second elastic arm 3 is arc-shaped, and the end of the arc-shaped is to inner side
Bending.Due to tail end and the ceiling linear contact lay of the second elastic arm 3, circular arc is set and ceiling when bending can make taking-up light fixture
It will not be scraped off.
Specifically, see Fig. 3, the height of second bending part 31（H1 in figure）Less than the height of the first bending part（Figure
In H3）；The height of second elastic arm tail end（H2 in figure）More than the height of the first bending part（H1 in figure）.To ensure
When two elastic arms 3 are pressurized, its tail end contacts with ceiling.
Further, Fig. 1-2 is seen, the end of the elongated hole 22 is circular arc, to eliminate stress concentration.
In the present embodiment, Fig. 1-4 are seen, the substrate 1 includes flat part 11, and two are symmetrically disposed in flat part
The auricle 12 of the left and right sides；A mounting hole 13 is offered on each auricle；The inside side of auricle is obliquely installed.Shell fragment uses screw
Or rivet, be fixed on the housing of light fixture by two mounting holes, the angle of inclination of auricle can be according to the diameter of lamp outer
It is adjusted, so as to be bonded during auricle installation with lamp outer even closer.
In addition, the substrate 1, the first elastic arm 2 and the second elastic arm 3 are integrally formed, specifically, entirely installing bullet
Piece is formed by manganese steel piece punching, as shown in fig. 6, then bending and molding on request.Whole shell fragment processing technology is simple, so as to improve
Production efficiency, reduce processing cost.
In summary, the utility model provides a kind of lamp installation shell fragment, and the lamp installation elastic piece structure is simple, uses
Convenient, after lamp installation is in the mounting hole of ceiling, the first elastic arm and the second elastic arm are squeezed frictional force more simultaneously
Greatly, and because the second elastic arm extends obliquely, its end contacts with ceiling, and frictional force thereon can make the second elastic arm
Reach self-locking effect so as to further increase frictional force with the trend opened outward, therefore effectively can prevent light fixture from sliding,
It is safe.In addition, the tail end of the second elastic arm is set to arc-shaped, and to inner side bending, scratch day when preventing from taking out light fixture
Card；It is circular arc the end of elongated hole, to eliminate stress concentration, improves service life；Mounting elastic sheet integrally punching after bending and
Into processing technology is simple, and processing cost is low.
It is understood that for those of ordinary skills, can according to the technical solution of the utility model and
The design of its utility model is subject to equivalent substitution or change, and all these changes or replacement should all belong to appended by the utility model
Scope of the claims.
