Abstract
The utility model discloses a connecting structure of a lighting fixture shell body. The connecting structure of the lighting fixture shell body is characterized by comprising a connecting body, wherein a section of the connecting body is in a U shape, two side boards of the connecting body with the U-shaped section are vertically connected with the inner wall of the shell body, a bottom board is arranged on the bottom of the connecting body, and a screw hole is arranged in the bottom board. According to the connecting structure of the lighting fixture shell body, by means of the connecting body with the U-shaped section, connecting firmness of the connecting body and the inner wall of the shell body is ensured, and a shrinking scar on the outer wall of the shell body on the position of the connecting body is avoided. Besides, due to the screw hole in the bottom board, the light fixture shell body is provided with the essential connecting structure enabling the shell body and a covering board to be connected.
Description
Technical field
The utility model relates to a kind of lighting, relates to specifically the syndeton between a kind of lamp casing and the cover plate.
Background technology
Lighting has a cover plate that is used for the housing of the components and parts such as mounting circuit boards and is used for housings close is got up usually.Inwall at housing need arrange several stud bolt holes so that by bolt housing and cover plate are coupled together.Existing stud bolt hole is generally a cylindrical shape, and an one limit is connected with the inwall of housing, at the center internal thread is set.Existing lighting housing and cover plate are that injection molding forms substantially, because comparing at all the other local thickness of thickness of shell and housing of stud bolt hole position will be greatly several times, in the cooling procedure after injection mo(u)lding, the stud bolt hole position shrinkage factor also than large several times of other positions of housing, cause the housing outer surface after the final molding that a contracting scar of sinking is arranged in the stud bolt hole position, affected the aesthetic property of light fixture, simultaneously, the contact area of columned stud bolt hole and inner walls is less, in actual use, stud bolt hole easily comes off from housing.
The utility model content
For overcoming defects, the utility model aims to provide a kind of can firmly being connected on the housing, simultaneously, can not cause the syndeton of contracting scar ground lamp casing in the injection mo(u)lding short range.
For achieving the above object, the technical solution adopted in the utility model is: a kind of syndeton of lamp casing, it is characterized in that it comprises a connector, the cross section of described connector takes the shape of the letter U, two side plates of the connector in described U-shaped cross section are connected with the inwall of housing is perpendicular, described connector bottom has a base plate, has a screw on the described base plate.
The centre position of described base plate has a technique cylinder mouth.
Adopted the syndeton of lamp casing of the present utility model, because having adopted the cross section is the connector of U-shaped, make connector and inner walls both guarantee the fastness that is connected, can not cause again simultaneously the housing outer wall of connector position that the contracting scar occurs, in addition, by the screw on the base plate, make lamp casing of the present utility model have the requisite syndeton that housing is connected with cover plate.
Description of drawings
Fig. 1 is structural representation of the present utility model;
Fig. 2 is use status architecture schematic diagram of the present utility model.
Among the figure: 1-connector, 2-housing, 3-base plate, 4-screw, 5-side plate, 6-technical gaps, 7-cover plate, 8-bolt.
The specific embodiment
As shown in Figure 1, the utility model discloses a kind of syndeton of lamp casing, its innovative point is that mainly it comprises a connector 1, the cross section of described connector 1 takes the shape of the letter U, two side plates 5 of the connector 1 in described U-shaped cross section are connected with the inwall of housing 2 is perpendicular, like this, make connector 1 have two limits to be connected with the inwall of housing 2, guaranteed the fastness that connector 1 is connected with housing 2 inwalls, simultaneously, because have a cavity between two side plates 5 of connector 1, make housing 2 thickness of connector 1 position and housing 2 consistency of thickness of other position, guaranteed after injection moulding is finished, to have identical shrinkage factor, avoided the generation of contracting scar on the housing 2.Described connector 1 bottom has a base plate 3, has a screw 4 on the described base plate 3.
In order further to reduce the possibility of the generation of contracting scar on the housing 2, the centre position of described base plate 3 has a technique cylinder mouth 6.So that the housing 2 of base plate 3 positions also has the shrinkage factor about the same with other position of housing.
As shown in Figure 2, the syndeton of lamp casing of the present utility model at first is placed on cover plate 7 on the opening of housing 2 when concrete the use, aligned position, then bolt 8 is passed cover plate 7, bolt 8 is threaded with screw 4 on the base plate 3, can simply be connected to cover plate 7 on the housing 2.
