The purpose of this utility model is achieved in that a kind of syndeton of case lid and casing of transformer, comprises case lid, casing, connecting screw rod and nut, wherein,
The upper end of four sidewalls of described casing has respectively and is outwards folded into horizontal direction case edge;
The edge of described case lid have be respectively folded into downwards vertically to lid eaves, the surface periphery size of case lid is greater than the Outside Dimensions on described case edge, some installing holes are offered in the surperficial edge of case lid respectively compartment of terrain; Described syndeton also comprises the briquetting consistent with the quantity of installing hole on described case lid;
Each briquetting comprises that a rectangular base plate and two are vertically connected on respectively the side plate on two long limits of base plate, has an inside ceiling panel and a roof sheet and take the shape of the letter U on every block of side plate, offers in the outer part a perforation on described base plate;
When described case lid covers on described casing, the below, the roof sheet that the inside ceiling panel of two blocks of side plates of described briquetting are placed in to described case edge are unsettled, with described connecting screw rod from the installing hole of case lid penetrate perforation the base plate of briquetting downwards and by nut by described briquetting to hanging oneself, until make the end face of the inside ceiling panel of briquetting support the lower surface on described case edge.
The case lid of above-mentioned transformer and the syndeton of casing, wherein, the width of the inside ceiling panel on described briquetting is greater than the width of roof sheet.
The case lid of above-mentioned transformer and the syndeton of casing, wherein, be also provided with seal between the upper surface on described case edge and the lower surface of case lid.
The technical scheme of the case lid of transformer of the present utility model and the syndeton of casing, employing is not offered installing hole on the case edge of casing, only on case lid, offer installing hole, and briquetting is hung until the inside ceiling panel of briquetting is supported the lower surface on case edge by being inserted in the connecting screw rod of the installing hole on case lid.By case lid, be connected with briquetting, case lid is connected with casing indirectly, the syndeton of transformer box cover of the present utility model and casing, not only can reduce the surface of transformer box cover and the surface on case edge and occur distortion, can also reduce the quantity of connecting screw rod, thereby reduce the installation workload of transformer.
Accompanying drawing explanation

Fig. 2 is the stereogram of briquetting in the case lid of transformer of the present utility model and the syndeton of casing.
Embodiment
Below in conjunction with accompanying drawing, the utility model is described in further detail.
Refer to Fig. 1 and Fig. 2, the case lid of a kind of transformer of the present utility model and the syndeton of casing, comprise case lid 1, casing 2, briquetting 3, seal 4, connecting screw rod 5 and nut 6, wherein, the upper end of four sidewalls of casing 2 has respectively and is outwards folded into horizontal direction case along 20; The edge of case lid 1 have be respectively folded into downwards vertically to lid eaves 10, the surface periphery size of case lid 1 is greater than the Outside Dimensions of case along 20, some installing holes are offered in the surperficial edge of case lid 1 respectively compartment of terrain; Briquetting 3 is consistent with the quantity of installing hole on case lid 1;
Each briquetting 3 comprises that a rectangular base plate 31 and two are vertically connected on respectively the side plate 32 on two long limits of base plate, have an inside ceiling panel 321 and a roof sheet 322 and take the shape of the letter U, and the width of inside ceiling panel 321 is greater than the width of roof sheet 322 on every block of side plate 32; On base plate 31, offer in the outer part a perforation 310;
Seal 4 is located at the upper surface of case along 20, and seal 4 is elastic rubbery body;
When case lid 1 covers on casing 2, the inside ceiling panel 321 of two blocks of side plates 32 of briquetting 3 is placed in to case unsettled along 20 below, roof sheet 322, with connecting screw rod 5 from the installing hole of case lid 1 penetrate perforation 310 base plate 31 of briquetting 3 downwards and by nut 6 by briquetting 3 to hanging oneself, until make the end face of the inside ceiling panel 321 of briquetting 3 support the lower surface along 20 at case.
The technical scheme of the case lid of transformer of the present utility model and the syndeton of casing, employing is not offered installing hole on the case 20 of casing, only on case lid 1, offer installing hole, and by being inserted in that the connecting screw rod 5 of the installing hole on case lid 1 hangs briquetting 3 until the inside ceiling panel 321 of briquetting 3 is supported the lower surface along 20 at case.Owing to thering is the width of the inside ceiling panel 321 on two blocks of side plates 32 and side plate 32 on briquetting 3 and be greater than the width of roof sheet 322, therefore increased briquetting 3 and the case contact area along 20, can reduce the surface of case lid 1 and the case surface along 20 and occur distortion.Syndeton of the present utility model is connected with briquetting 3 by case lid 1, case lid 1 is connected with casing 2 indirectly, surface and the case that not only can reduce case lid 1 are out of shape along 20 surface appearance, can also reduce the quantity of connecting screw rod 5, thereby reduce the installation workload of transformer.
Above embodiment is only for illustration of the utility model, but not to restriction of the present utility model, person skilled in the relevant technique, in the situation that not departing from spirit and scope of the present utility model, can also make various conversion or modification, therefore all technical schemes that are equal to also should belong to category of the present utility model, should be limited by each claim.
