Detailed description of the invention
Main in conjunction with the drawings and the specific embodiments to lamp casing and use the light fixture of this lamp casing to be described in further detail below.
The light fixture of one embodiment comprises fixed support, ballast and light source (not shown).Wherein, light source is fixed on fixed support.In addition, the light fixture of present embodiment also comprises lamp casing 100, as shown in Figure 1.Lamp casing 100 is fixed on fixed support, and ballast is located in lamp casing 100.
Incorporated by reference to Fig. 2, the lamp casing 100 of present embodiment comprises threaded fastener 110, main part 120 and cover plate 130.Wherein, main part 120 is provided with the screw 122 with threaded fastener 110 adaptation.Cover plate 130 is provided with and threaded fastener 110 and screw 122 through hole 132 accordingly.Threaded fastener 110 can be screwed by through hole 132 and screw 122 and main part 120 and cover plate 130 is fixed together and form lamp casing 100.Main part 120 and cover plate 130 internal notches, the two is engaged in the inner receiving space (not indicating in figure) forming a collecting ballast.
Please refer to the drawing 3, threaded fastener 110 comprises head 112, threaded portion 114 and polished rod portion 116.Head 112 is roughly in oblate column, and a side end face offers " ten " word swivelling chute or " one " word swivelling chute.In other embodiments, head 112 can also be polygonal prism type etc.Threaded portion 114 is connected with the side of head 112, which is provided with screw thread.Polished rod portion 116 is connected with one end of threaded portion 114.The diameter in polished rod portion 116 is less than the diameter of threaded portion 114, and that effectively can shorten threaded fastener 110 and screw 122 screws the time, makes installation or removal convenient.Further, in the present embodiment, the screw thread of threaded portion 114 cylinder of the whole threaded portion 114 of non-covered, but arrange in the one end near polished rod portion 116, part polished rod region is had, because this part is positioned at cover plate 130 when mounted, therefore in the one end near head 112, adopt this structural design effectively can save the process time of parts, reduce costs.
Please refer to the drawing 1 and Fig. 2, main part 120 offers screw 122.In the present embodiment, main part 120 is roughly square, and inside offers storage tank.Screw 122 is opened in the position at four angles of square main part 120.Be understandable that, in other embodiments, the shape of main part 120 is not limited thereto, and can also be cylinder etc., the quantity of its screw 122 and distributing position can be joined concrete condition and establish.
Incorporated by reference to Fig. 4, Fig. 5 and Fig. 6, the openend shape adaptation of cover plate 130 and main part 120 is also square.Cover plate 130 offers through hole 132 respectively in the position at four angles.The diameter of through hole 132 is less than the diameter of the head 112 of threaded fastener 110, but is greater than the diameter of threaded portion 114, thus threaded fastener 110 can screw in screw 122 through through hole 132, cover plate 130 and main part 120 is fixed together.
In the present embodiment, cover plate 130 offers along the axially extended opening 134 of hole wall at the hole wall of through hole 132.Opening 134 is opened in towards on the hole wall outside cover plate 130, and opening 134 be opened near main part 120 one end hole wall on and extend axially to this end.Threaded fastener 110 can tilt through this opening 134, as shown in Figure 4.Further, cover plate 130 is provided with the locating part preventing threaded fastener from moving axially on the hole wall of open section.In the present embodiment, locating part comprises two and is set in parallel in rib 136 on hole wall.In the radial direction of through hole 132, the distance between two ribs 136 is consistent with the diameter of threaded portion 114.Pitch between the height of each rib 136 and the adjacent thread tooth of threaded portion 114 is consistent.At through hole 132 axially, two ribs 136 stagger setting, and the difference in height Δ h between two ribs 136 meets following relation:
Δh＝n*t+(n-1)*p；
Wherein, n is natural number, and t is the ridge thickness of threaded portion 114, and p is the pitch between the adjacent thread tooth of threaded portion 114.In the present embodiment, n=1, also namely two ribs 136 define one section of screw thread coordinated with threaded portion 114 on through-hole wall, therefore, after threaded fastener 110 departs from main part 120, because two ribs are relative to one section of screw thread, therefore, threaded fastener 110 is difficult to depart from through hole 132 and drop.
Be understandable that, in other embodiments, the structure of locating part is not limited to two ribs be arranged in parallel 136, as the elastic component etc. be oppositely arranged, can also being limited in by threaded fastener 110 in through hole 132 and not dropping by the elasticity conflict effect of elastic component.
Above-mentioned lamp outer casing 100 is when dismounting, unscrew securing member 110, when threaded portion 114 on threaded fastener 110 throws off the screw thread of main part 120 completely, cover plate 130 can be taken away, locating part in cover plate through hole 132 can prevent threaded fastener 110 from moving axially, therefore threaded fastener 110 can not be separated automatically with cover plate 130, prevents threaded fastener 110 to get loose loss.If need to change threaded fastener 110, only need opening 134 direction of threaded fastener 110 lower end edge cover plate 130 to tilt pull-out, then threaded fastener 110 is ejected through hole 132.
The above embodiment only have expressed several embodiment of the present invention, and it describes comparatively concrete and detailed, but therefore can not be interpreted as the restriction to the scope of the claims of the present invention.It should be pointed out that for the person of ordinary skill of the art, without departing from the inventive concept of the premise, can also make some distortion and improvement, these all belong to protection scope of the present invention.Therefore, the protection domain of patent of the present invention should be as the criterion with claims.
