Described cylinder 20 is a right cylinder, but is not limited to the right cylinder of present embodiment, also can be rectangular parallelepiped, only need with connected spare part on corresponding the getting final product of shape in hole.
Described each holding section 30 comprises a butting section 32 and a connecting portion 34.Described butting section 32 is a ramp structure that increases gradually along the direction away from pedestal 10, and it has an abutment face 35 relative with described pedestal 10, states spare part (scheming not show) against the residence in order to match with pedestal 10.One end of described connecting portion 34 connects described cylinder 20, and the other end connects the abutment face 35 of described butting section 32.Described against and 35 and the spare part that all is connected of described pedestal 10 (figure does not show) with needs closely contact just can be with the firm connection of spare part.Described butting section 32 is included in described connecting portion 34 with respect to the orthogonal projection plane of pedestal 10 (figure does not show) with respect to the orthogonal projection plane (figure does not show) of pedestal 10 in.The appearance integral of described connecting portion 34 should cooperate the shape that is connected the hole of offering on the spare part (figure do not show) and can be with the firm connection of spare part.Described each holding section 30 forms gap 40 so that holding section 30 has certain extendable room when being extruded for being provided with at interval each other.Preferably, elastic material is adopted in described holding section 30, such as plastics, elastic sheet metal etc.
The quantity that is appreciated that holding section 30 is not limited to four in the present embodiment, can for two, three or more, only need have certain shrink space and firm the linking together of spare part got final product.
See also Fig. 1 and Fig. 2, wherein Fig. 2 is the view that bayonet unit 100 connects the projection arrangement spare part among Fig. 1.Projection arrangement comprises one first plate 50 and one second plate 60.Have one first surface in contact 52 on described first plate 50, and first through hole 54 that connects first plate 50, have one second surface in contact 62 on described second plate 60, and second through hole 64 that connects second plate 60.Wherein, described first through hole 54 and second through hole 64 are the regular circular through hole, and the one-piece construction of the connecting portion 34 of described bayonet unit 100 is corresponding with manhole.
When user's desire uses bayonet unit 100 that first plate 50 is connected with second plate 60, can push bayonet unit 100 by described pedestal 10, make described holding section 30 and cylinder 20 be arranged in described first through hole 54 and second through hole 64 successively, gap 40 provides certain shrink space for the holding section 30 of elastic construction, when first through hole 54 and second through hole 64 are passed through fully in the butting section 32 of holding section 30, pedestal 10 closely contacts with first surface in contact 52 of first plate 50, realizes that the firm of spare part is connected thereby abutment face 35 closely contacts with second surface in contact 62 of second plate 60.
Described bayonet unit 100 utilizes the abutment face 35 of described butting section 32 and pedestal 10 closely contacts with spare part and realization the firm of spare part is connected, and the holding section 30 that is provided with at interval becomes easily the connection of spare part simultaneously, has improved the work efficiency of assembling procedure.
Second embodiment
See also Fig. 3, it is bayonet unit 100 ' the user mode synoptic diagram of second embodiment, be with the difference of bayonet unit 100 user modes of first embodiment: first through hole 54 ' still is the regular circular through hole, and the plane that second through hole 64 ' is intercepted by the plane perpendicular to pedestal 10 is up-small and down-big trapezoidal, and the one-piece construction of the connecting portion 34 ' of described bayonet unit 100 ' is corresponding with second through hole 64 '.Described connecting portion 34 ' is included in described butting section 32 ' with respect to the orthogonal projection plane of pedestal 10 (figure does not show) with respect to the orthogonal projection plane (figure does not show) of pedestal 10 in.
The 3rd embodiment
See also Fig. 4, be the bayonet unit 100 of the 3rd embodiment " the user mode synoptic diagram; be with the difference of bayonet unit 100 user modes of first embodiment: first through hole 54 " still be the regular circular through hole, and second through hole 64 " be up-small and down-big trapezoidal by the plane that intercepts perpendicular to the plane of pedestal 10, described bayonet unit 100 " connecting portion 34 " the one-piece construction and second through hole 64 " corresponding.Described connecting portion 34 " with respect to orthogonal projection plane of pedestal 10 (figure does not show) and described butting section 32 " overlapping with respect to the orthogonal projection plane (figure does not show) of pedestal 10.
Further, bayonet unit can be molded directly within on the housing of projection arrangement among above-mentioned first embodiment to the, three embodiment.As example, see also Fig. 5, be that the bayonet unit 100 of first embodiment is arranged at the schematic perspective view on the projection arrangement housing 200, this housing 200 comprises a base plate 10 ', described base plate 10 ' is the pedestal 10 of bayonet unit 100.
See also Fig. 5 and Fig. 6, wherein Fig. 6 is the view that Fig. 5 middle shell 200 uses in projection arrangement.Projection arrangement comprises a plate 70, as the cover plate on the light supply apparatus.Described plate 70 has one first surface in contact 72, second surface in contact 74, and through hole 76 that runs through described plate 70.
When user's desire is fixed to plate 70 on the housing 200, described cylinder 20 and holding section 30 wear described through hole 76, gap 40 provides certain shrink space for the holding section 30 of elastic construction, when through hole 76 is passed through fully in the butting section 32 of holding section 30, base plate 10 ' closely contacts with second surface in contact 74 of plate 70, realizes that the firm of spare part is connected thereby abutment face 35 closely contacts with first surface in contact 72 of plate 70.
Described housing 200 utilizes the abutment face 35 of described butting section 32 and base plate 10 ' closely contacts with spare part and realization the firm of spare part is connected, and the holding section 30 that is provided with at interval becomes easily the connection of spare part simultaneously, has improved the work efficiency of assembling procedure.
Be understandable that, for the person of ordinary skill of the art, can make other various corresponding changes and distortion by technical conceive according to the present invention, and all these change the protection domain that all should belong to claim of the present invention with distortion.
