Also referring to Fig. 1 to Fig. 4, now retaining mechanism 10 provided by the utility model is illustrated.The retaining mechanism 10 housing 21 and face ring 22 for locking light fixture 20, the light fixture 20 can be Down lamp or shot-light, and certainly, other have housing 21 The scope of protection of the utility model is belonged to the light fixture 20 of face ring 22.

Above-mentioned retaining mechanism 10 includes locating dowel 11 and two armfuls being symmetricly set in face ring 22 on housing 21 Pawl 12, the peripheral surface that holding claw 12 includes being used to hold locating dowel 11 tightly are clasped portion 121 and are connected and with clasping portion 121 for supporting The blocking part 122 of the axial end of locating dowel 11 is kept off, portion 121 is clasped for two and is oppositely arranged to be formed for holding locating dowel 11 tightly Hold space 123 tightly.

Also referring to Fig. 1 to Fig. 4, retaining mechanism 10 provided by the utility model, compared with prior art, when light fixture 20 During using the above-mentioned locking shell 21 of retaining mechanism 10 and face ring 22, the locating dowel 11 on housing 21 can from top to bottom be extruded and embraced by it Pawl 12, holding claw 12 are opened outside, and locating dowel 11 is coordinated with holding space 123 tightly, and now, the axial end of locating dowel 11 is by blocking part 122 are kept out, and the peripheral surface of locating dowel 11 is clasped portion 121 and held tightly, and so, locating dowel 11, which will be fixed on, holds space tightly In 123, so that housing 21 is fixedly connected with face ring 22, compared to more existing for locking by the way of screw, as long as it is logical Cross to push locating dowel 11 to get into and hold space 123 tightly, efficiency of assembling is high, beneficial to automated production, moreover, eliminating screw Part, cost is saved.

It should be added that clasping, portion 121 is flexible, and so, it can hold locating dowel 11 tightly by elastic force.

Also referring to Fig. 1 to Fig. 4, in order that portion 121 must be clasped and the shape of locating dowel 11 is mutually fitted, it is each to clasp portion 121 have the cambered surface 1211 being used for the peripheral surface obvolvent of locating dowel 11, and two cambered surfaces 1211 are symmetrical arranged is held tightly with being formed Space 123.Wherein, the locating dowel 11 is cylinder, when locating dowel 11, which is placed in, holds tightly in space 123, the circumference of locating dowel 11 Surface will be more bonded with cambered surface 1211, and cooperation of the locating dowel 11 with clasping portion 121 will be consolidated more.

In order to further cause cooperation of the locating dowel 11 with clasping portion 121 to consolidate, two cambered surfaces 1211 are located at together On heart circle.Wherein, when locating dowel 11, which is placed in, holds tightly in space 123, the center of circle of the circular cross-section of locating dowel 11 and two cambered surfaces The center of circle of concentric circles where 1211 is in same point, and so, the peripheral surface of locating dowel 11 will be more bonded with cambered surface 1211.

Also referring to Fig. 1 to Fig. 4, refinement ground, concentric diameter of a circle is less than the diameter of locating dowel 11.So, positioning is worked as When post 11 is placed in holding space 123, the cooperation of cambered surface 1211 and locating dowel 11 will be interference fit, so, fixed beneficial to causing Cooperation of the position post 11 with clasping portion 121 consolidates.

Held tightly in order that obtaining locating dowel 11 and successfully can get into from top to bottom in space 123, clasp the upside shape in portion 121 Cheng Youyu cambered surfaces 1211 connect and for locating dowel 11 to be guided to the guide surface 1212 in cambered surface 1211.And ground is more refined, Interval between two guide surfaces 1212 tapers into from top to bottom.So, guide surface 1212 and the connection transition position of cambered surface 1211 It will be in shrink mouth shape to put, and when assembling locating dowel 11, locating dowel 11 will be sequentially by guide surface 1212 and necking, and enters and hold space tightly 123, and after locating dowel 11 falls into and holds space 123 tightly, necking is advantageous to prevent locating dowel 11 easily from holding space 123 again Middle abjection.

Also referring to Fig. 1 to Fig. 4, ground, for the ease of locating dowel 11 is guided to cambered surface 1211, guide surface are refined 1212 are clinoplain or tilt curved surface.Specifically, as long as guide surface 1212 it is round and smooth excessively face.

On the preferred embodiment of specific set location of the holding claw 12 in face ring 22, face ring 22 has annular in shape enclose Wall 221, leg 221 are provided with the groove 222 of upper side opening, and two holding claws 12 are located in groove 222.So, can be easy on toward Lower assembling locating dowel 11, locating dowel 11 will first pass through the opening of groove 222, then enter back into empty to the holding between two holding claws 12 Between in 123.

Also referring to Fig. 1 to Fig. 4, when locating dowel 11 is pressed down against clasping portion 121, deformation can be passed through by clasping portion 121 To hold locating dowel 11 tightly, and due to blocking part 122 and the integrally connected of portion 121 is clasped, therefore, blocking part 122 can also occur accordingly Deformation, in order to adapt to the deformation, specifically, blocking part 122 have be used for keep out locating dowel 11 axial end big end 1221 and the small ends 1222 that are connected and are connected with the bottom of groove 222 with big end 1221, deposited between blocking part 122 and leg 221 At interval 1223.So, due to the presence at interval 1223 so that blocking part 122 has the space of deformation.

Refinement ground, in order to preferably cause the stable connection between housing 21 and face ring 22, the quantity of locating dowel 11 is set to At least two, the quantity of holding claw 12 is set at least four, each locating dowel 11 with a pair of corresponding matchings of holding claw 12.

Also referring to Fig. 1 to Fig. 4, the utility model additionally provides light fixture 20, and it includes housing 21, face ring 22 and set Retaining mechanism 10 between housing 21 and face ring 22.

When light fixture 20 is using the above-mentioned locking shell 21 of retaining mechanism 10 and face ring 22, it can be by the locating dowel on housing 21 11 extrude holding claw 12 from top to bottom, are opened outside holding claw 12, and locating dowel 11 is coordinated with holding space 123 tightly, now, locating dowel 11 Axial end is kept out by blocking part 122, and the peripheral surface of locating dowel 11 is clasped portion 121 and held tightly, so, locating dowel 11 It will be fixed on and hold tightly in space 123, so that housing 21 is fixedly connected with face ring 22, compared to the more existing side using lock screw For formula, as long as it holds space 123 tightly by pushing locating dowel 11 to get into, efficiency of assembling is high, beneficial to automated production, Moreover, eliminating screw part, cost has been saved.

In addition, being provided with light source, drive device 23 and circuit board 24 in housing 21, diffuser 25 is installed in face ring 22.

Preferred embodiment of the present utility model is these are only, it is all in this practicality not to limit the utility model All any modification, equivalent and improvement made within new spirit and principle etc., should be included in guarantor of the present utility model Within the scope of shield.
