Aiming at the defects of troublesome installing, inconvenient operation, great disassembling difficulty of the transparent piece in the prior art, the utility model provides a lamp housing which is simple in structure, convenient to assemble and disassemble, and fast to operate.
Description
Technical field
The utility model belongs to lighting technical field, relates to a kind of lamp attachment, relates in particular to a kind of lamp outer casing.
Background technology
Lamp outer casing is the critical piece of light fixture, generally form by main casing and Transparent Parts, owing to be provided with light source in the main casing, light source is the consumable accessory of light fixture, need to change, during replacing, generally need Transparent Parts is removed from main casing, therefore, Transparent Parts fixedly be dismountable, in the fixed form of existing Transparent Parts, more common be screwed, washer pressing and fixing greatly, on aluminium matter lamp holder, done in addition one can bending compressing tablet to the Transparent Parts pressing and fixing, these fixed forms are installed trouble, operation inconvenience.The light fixture that uses of some high-altitudes particularly, the dismounting difficulty is very big.
The utility model content
The technical problems to be solved in the utility model is, at Transparent Parts in the prior art trouble, operation inconvenience, the bigger defective of dismounting difficulty is installed, and a kind of simple in structure, easy installation and removal, lamp outer casing swift to operate are provided.
The technical scheme that its technical problem that solves the utility model adopts is: a kind of lamp outer casing, comprise main casing, be arranged on the Transparent Parts of main casing front end and transverse seal main casing, described main casing front inner wall is provided with draw-in groove, be connected with snap ring radially scalable and roof pressure draw-in groove inwall in the described draw-in groove, the main casing inwall at described draw-in groove rear is provided with block piece, and described Transparent Parts is pressed abd fixed between the two by snap ring and block piece.
Described draw-in groove is the annular groove that the main casing front inner wall radially forms to the wall indent.
The shape of cross section of described draw-in groove is circular arc, V font, polygon or irregularly shaped, and described snap ring outer side surface is consistent with the draw-in groove form fit.
Diameter under the described snap ring nature is a bit larger tham the draw-in groove internal diameter.
Described snap ring axial width is consistent with the cooperation of draw-in groove width, and the two end play cooperates, and described snap ring radial thickness makes snap ring partly be positioned at draw-in groove, partly be pressed on the Transparent Parts greater than the draw-in groove degree of depth.
Described snap ring is the torus that is provided with an opening, and spacing is left at the torus two ends of opening part.
Described snap ring is the torus that head and the tail overlap.
Draw-in groove and the snap ring cooperation clamping of elastic stretch radially outward that the utility model utilization is provided with in the main casing front inner wall, form a detachable fixing hold-down mechanism, owing to can radially outward uphold after snap ring shrinks in advance, snap ring is placed on snap ring in the draw-in groove after shrink at the center again, snap ring because the elastic compression draw-in groove is upheld in the elastic force effect, is realized the two flexible clamping radially in draw-in groove.Because snap ring partly is positioned at draw-in groove, it is spacing to be subjected to draw-in groove, and then snap ring cooperates before and after the two at the block piece that is provided with on the main casing inwall at axially snap ring and draw-in groove rear and compresses Transparent Parts, and Transparent Parts axially just is being fixed on the main casing like this.Of the present utility model simple in structure, installation and removal all very efficient and convenient, in very short time, just can finish the disassembling, assembling and replacing operation, improved efficient.
Description of drawings
The utility model is described in further detail below in conjunction with drawings and Examples, in the accompanying drawing:
Fig. 1 is the explosive view of the utility model embodiment;
Fig. 2 is the cutaway view after the utility model embodiment assembling;
Fig. 3 is the partial enlarged drawing at I place among Fig. 2.
The specific embodiment
As shown in Figure 1, 2, 3, a kind of lamp outer casing, comprise front opening main casing 3, be arranged on the Transparent Parts 2 of main casing 3 front ends and transverse seal main casing 3, the two is combined to form a complete lamp housing.Main casing 3 is a tubular, and its cross section is a polygon such as circular, oval, square, also can be irregularly shaped.The main casing 3 of present embodiment is cylindric.Transparent Parts 2 corresponds to disc.Described main casing 3 front inner wall are provided with draw-in groove 5, be connected with the snap ring 1 of elastic stretch radially outward and roof pressure draw-in groove 5 inwalls in the described draw-in groove 5, main casing 3 inwalls at described draw-in groove 5 rears are provided with block piece 31, and described Transparent Parts 2 is pressed abd fixed between the two by snap ring 1 and block piece 31.Snap ring 1 and block piece 31 shapes all are annular in the present embodiment.
Because Transparent Parts 2 is radially fixing along main casing 3, then described draw-in groove 5 is the annular groove that main casing 3 front inner wall radially form to the wall indent, and the opening of draw-in groove 5 is towards the axis of main casing 3.Draw-in groove 5 can parallel main casing 3 front end faces, also can be obliquely installed, and is in a certain angle with main casing 3 front end faces.
Shown in Fig. 2,3, described snap ring 1 axial width is consistent with the cooperation of draw-in groove 5 width, and the two end play cooperates, and described snap ring 1 radial thickness makes snap ring 1 part be positioned at draw-in groove 5 greater than draw-in groove 5 degree of depth, and part is pressed on the Transparent Parts 2.The shape of cross section of described draw-in groove 5 is circular arc, V font, polygon or irregularly shaped, snap ring 1 part is connected in the draw-in groove 5, described snap ring 1 outer side surface is consistent with draw-in groove 5 form fit, make snap ring 1 can stablize and be connected in the draw-in groove 5, just can play the axial limiting of Transparent Parts 2 is fixed with the part of draw-in groove 5 clampings.
Diameter under snap ring 1 nature is a bit larger tham draw-in groove 5 internal diameters.1 one kinds of embodiments of described snap ring are: snap ring 1 is for being provided with the torus of an opening, and spacing is left at the torus two ends of opening part.Because the diameter under snap ring 1 nature is a bit larger tham draw-in groove 5 internal diameters, draw-in groove 5 internal diameters are meant the diameter of the formed annular of groove bottom of draw-in groove 5.In use, radially to the center extruding, because opening exists, snap ring 1 radial contraction, diameter diminish, and just can be placed in the draw-in groove 5 with snap ring 1, place back snap ring 1 elastic reaction and radially outward uphold reinstatement, and just elastic top is pressed in the draw-in groove 5.
Described snap ring 1 another kind of embodiment is: the torus that described snap ring 1 overlaps for head and the tail.Snap ring 1 is that the strip piece bending becomes torus, and the strip piece two ends overlap mutually, but unfixing, so under external force, snap ring 1 diameter can change, and resilience is shunk, decontroled in extruding, realizes that snap ring 1 is installed and chucking main casing 3 inwalls.
