Combined and spliced formula distribution box body
Technical field
The utility model relates to a kind of electricity consumption distribution box, is specifically related to a kind of combined and spliced formula distribution box body structure.This distribution box body is combined and spliced the forming of cell cube made from by three molds when producing, and reaches the various distribution box length that the user needs with this.
Background technology
The resident's power supply and the industrial or agricultural electric power system distributed areas of China are huge, and electric power system terminal---distribution box spreads all in each family and all kinds of industrial and mining enterprises in town and country.In the city domestic power grid was transformed, distribution box played the effect of metering and judgement transmission or not because it makes things convenient for transmission or not, is widelyd popularize.
The casing of distribution box commonly used part mainly is made up of the distribution chamber door that is provided with on a uncovered rectangular box and the casing at present, wherein uncovered rectangular box is by a backboard and four side sidewalls are integrated up and down, be to make mould during production by the Len req size, one-body molded then.And when the length dimension specification of product changes, die sinking tool in addition again, promptly can only produce a kind of product of length dimension specification with a mold, therefore, manufacturer is to open a series of mould according to the variation of various sizes when producing at present, produce big and small a series of distribution box with this, thereby caused the high of distribution box production cost.
Summary of the invention
The utility model provides a kind of combined and spliced formula distribution box body, and purpose is the quantity of die sinking when reducing the production of different length dimensions with the structure that unit combination is spliced, and reduces the production cost of distribution box body.
For achieving the above object, the technical solution adopted in the utility model is: a kind of combined and spliced formula distribution box body, form by upper head plate, bottom plate and at least one " U " type frame; Described " U " type frame is one-body molded by backboard and left and right sides plate; U " in the two ends up and down of type frame, an end end is along being provided with chimb, and other end end is provided with caulking groove along last depression; In described upper head plate and the bottom plate, the chimbs of upward corresponding " U " type frames are provided with the caulking groove of inlay card cooperation with it, and the caulking groove that another person goes up corresponding " U " type frame is provided with the chimb of inlay card cooperation with it.
Related content in the technique scheme is explained as follows:
1, in the such scheme, described casing comprises " U " type frame of at least two, the chimb of each " U " type frame one end and the caulking groove size of the other end are complementary, be arranged above and below successively with this this at least two " U " type frames, be connected with caulking groove inlay card on adjacent another person with the chimb between two adjacent " U " type frames.
2, in the such scheme, described each chimb and caulking groove inlay card place wear bolt along the chimb thickness direction and connect.
3, in the such scheme, described bolt head is positioned at box inside, and the corresponding nut of its casing appearance is provided with groove, and nut embeds in the groove and is threaded with the bolt tail end.
4, in the such scheme, between the chimb and caulking groove of described phase inlay card, one are provided with hangnail, and another person goes up the handicapping stopper, and hangnail is stuck on the stop part, thereby chimb is also fixedlyed connected with the caulking groove inlay card.
Because the technique scheme utilization, the utility model compared with prior art has following advantage:
1,, thereby reaches the purpose of the length that increases distribution box because the utility model employing is made up of upper head plate, bottom plate and " U " type frame of at least one, and the quantity of " U " type frame can increase at any time according to user's needs.
2, because the utility model is by a plurality of " U " type frame, a upper head plate and a bottom plate are formed, and a plurality of " U " type frame is that same structure is arranged above and below successively, and the chimb of each " U " type frame one end and the caulking groove size of the other end are complementary, be connected with caulking groove inlay card on adjacent another person with the chimb between two adjacent " U " type frames, these " U " type frames only need be offered a tool mould and get final product, it is whole distribution box, length dimension size no matter, all only need offer three tool moulds and can finish assembling, institute's die sinking tool number is little, thereby greatly reduces the production cost of distribution box.
3, the utility model good airproof performance, bonding strength height, good waterproof performance.
