Abstract
The project of the invention is to provide a ballast box body, capable of being conjoined tightly and reliably. The ballast box body includes a box base and a box cover, the side walls of the box base are provided with necks, the box cover is provided with buckles matching with the necks at positions corresponding to the necks, the side face of each neck is provided with a locking projections for locking the buckle, the inner side face of each buckle and the bottom face of each neck are provided with a hollow part and a structure for abutting and cooperating with the projection. The necks of the utility model may buckle the buckles of the box cover by the locking projections projected inwards from the side wall, such that the buckles will be folded outwards or broke, and the connection of the box cover and the box base is tight and reliable; because the necks are concave and will not project outward the box body, the connection portion of the box cover and the box base is more smooth.
Description
Technical field
The utility model relates to the technical field of electrical equipment, particularly a kind of ballast box body.
Background technology
Existing illuminating lamp ballast box body is divided into lid and cassette holder two parts usually, and the buckle of lid by its edge setting blocks the cassette holder edge and finish being connected of lid and cassette holder.The outer box of the ballast of this structure, outwards bending distortion or fracture easily in the process that is buckled in dismounting of lid, in case and degree of its chucking cassette holder of buckle distortion back will reduce, become flexible thereby cause lid to be connected appearance with cassette holder; Because ballast generally is mounted in the fluorescent lamp box, need the box body periphery all not have ledge simultaneously, just need lid and cassette holder junction level and smooth.
Summary of the invention
The purpose of this utility model is to propose the closely reliable ballast box body of a kind of clamping.
To achieve these goals, ballast box body of the present utility model, comprise cassette holder and lid, key is: the sidewall of described cassette holder is provided with draw-in groove, the position of the corresponding draw-in groove of described lid is provided with the buckle that cooperates with draw-in groove, the side of described draw-in groove is provided with the lock tab that inwardly is used to lock buckle, and the medial surface of described buckle and the bottom surface of draw-in groove are provided with the clamping fit structure of hollow-out parts and projection.
The utility model is by tightening the draw-in groove of the buckle on the lid in the sidewall setting of cassette holder, buckle on the lid injects in the draw-in groove and cooperates with the lid clamping with the structure of projection by hollow-out parts, the buckle that the lock tab that draw-in groove inwardly is provided with by the side can tighten lid can outwards not bend or fracture it, and can not become flexible, guarantee that the clamping of lid and cassette holder is closely reliable; Because draw-in groove is an indent, can not give prominence to simultaneously to the box body periphery.
Described draw-in groove reduces gradually along the width of buckle grafting direction.Draw-in groove reduces gradually and can play good guide effect to the buckle grafting along the width of buckle grafting direction.
Described projection is the inclined-plane towards the one side of installation direction.The projection that is used to connect buckle and draw-in groove is along the bayonet socket into direction of draw-in groove of pegging graft, and just the one side of installation direction is that the inclined-plane play the guiding role, and makes things convenient for buckle to be seated in the draw-in groove.
Described lock tab is symmetrically arranged in the both sides of draw-in groove opening.The both sides that lock tab is arranged symmetrically in the draw-in groove opening allow buckle design thicklyer, and structure is firmer, and lock tab becomes both sides to arrange and have only a side to arrange to compare, can make the buckle two ends stressed evenly.
Described lock tab is cuboid or prismatic projection.Lock tab can be cuboid, the rectangular structure handling ease, and the cross sectional shape of corresponding buckle is a rectangle.Lock tab also can be the prismatic projection, and the cross sectional shape of corresponding buckle is trapezoidal, and the rigidity of prismatic projection is stronger, and structure is more firm.
The junction of described lid and cassette holder is provided with the step-like support portion of working in coordination.Work in coordination and can play support, firm effect in the support portion of lid and cassette holder, and the whole edge of lid and cassette holder is evenly stressed when mounted in step-like support portion, can prevent that buckle is owing to the problem of having only the stressed easy fracture that produces of root.
The medial surface of described buckle is provided with hollow-out parts, and the bottom surface of draw-in groove is provided with the projection that cooperates with this hollow-out parts.The medial surface that also can be described buckle is provided with projection, and the bottom surface of draw-in groove is provided with the hollow-out parts that cooperates with this projection.The buckle of lid cooperates with the clamping of hollow-out parts and the cassette holder clamping by projection.
The lock tab that draw-in groove of the present utility model inwardly is provided with by the side can tighten the buckle of lid, it can outwards not bent or fracture, and can not become flexible, and guarantees that the clamping of lid and cassette holder is closely reliable; Because draw-in groove is an indent, can not give prominence to simultaneously, make lid and cassette holder junction more level and smooth to the box body periphery.

Embodiment
Describe the utility model in detail below in conjunction with specific embodiments and the drawings.
As shown in Figure 1, 2, 3, ballast box body of the present utility model, comprise cassette holder 1 and lid 2, the sidewall of described cassette holder 1 is provided with draw-in groove 11, the position of described lid 2 corresponding draw-in grooves 11 is provided with the buckle 21 that cooperates with draw-in groove 11, the side of described draw-in groove 11 is provided with the lock tab 12 that inwardly is used to lock buckle 21, and the medial surface of described buckle 21 is provided with hollow-out parts 22, and the bottom surface of described draw-in groove 11 is provided with projection 13 and cooperates with hollow-out parts 22 clampings.Described draw-in groove 11 reduces gradually along the width of the grafting direction of buckle 21.Described projection 13 is the inclined-plane towards the one side 14 of installation direction.Described lock tab 12 is symmetrically arranged in the both sides of draw-in groove 11 openings.Described cassette holder 1 is provided with step-like support portion 15, and described lid 2 is provided with the step-like support portion 23 that cooperates with the support portion 15 of cassette holder 1.
As shown in Figure 4, described lock tab 12 is a cuboid, and the cross sectional shape of corresponding buckle 21 is a rectangle.
