Abstract

The utility model relates to a distributing box free from screws, which mainly comprises a box body and a box cover. The box body is provided with an opening and the box cover seals the opening. The utility model is characterized in that the box cover is provided with a positioning convex column. The end of the positioning convex column is provided with a groove to form a cross shape and integrated with a positioning hole arranged at the corresponding position of the box body in a scarf joint manner. The end of the positioning convex column is in scarf joint in the positioning hole of the box body in an elastic manner. The box cover can be fixed without screws through the elasticity of materials. Additionally, the outer margin of the opening of the box body or the box cover is provided with a concave pit. When the box cover needs to be opened, the box cover is prized by implementing force on the concave pit. Therefore, the utility model is convenient to distribution construction.

Description

Exempt from distributing box with screw

Technical field

The utility model relates to distributing box, refers to a kind of industrial distributing box of exempting to use screw especially.

Background technology

As shown in Figure 1, known distributing box 10 is generally metallic article, can directly be fixed on the wallboard with screw, but will be fixed on the screw rod 11, then must could finish screw rod 11 fixing with screw 12 and special-purpose metal butt strip 13 then earlier in box subdrilling hole, tapping.In addition, known distributing box 10 sides have through hole, make the fixing head of cable (Glands) 14 pass use.Distributing box 10 is provided with lid, but must use screw to fix, and time-consuming taking a lot of work caused waste.

Novel content

Main purpose of the present utility model is to make the lid of distributing box can exempt from can cover tight or open with screw under general state, make the distribution construction save time more, laborsaving.

For reaching above-mentioned purpose, a kind of distributing box of exempting from screw, mainly comprise a box body and a lid, box body is provided with an opening, lid is sealed opening, it is characterized in that: establish a location projection at lid, the positioning convex column end is established groove and is formed the jag shape, and is halved together with location hole that the box body relative position is provided with and is one.

The utility model also can be realized by following scheme: a kind of distributing box of exempting from screw, comprise a box body and a lid, box body is provided with an opening, lid is sealed opening, it is characterized in that: lid is provided with a location projection, is provided with a centre bore in the positioning convex column, and its end is the jag shape, location hole interlocking with the box body relative position is provided with is provided with an aperture in this location hole.

Because the utility model is provided with the positioning convex column of a terminal jag at lid, so improved the elasticity of material, makes lid not need screw to fix.When opening lid, the pit application of force of lid pried open get final product, be convenient to construct, time saving and energy saving, and improved operating efficiency.

Embodiment

For structure of the present utility model, annexation and effect thereof are had further understanding, conjunction with figs. and embodiment are described as follows now:

Consult shown in Figure 2ly, a kind of distributing box 20 of exempting from screw mainly comprises a box body 21 and a lid 22; Box body 21 utilizes the plastics ejection formation with fire protecting performance with lid 22, establishes at least one pair of jig arm 214 in the bottom of box body 21, and this jig arm 214 can be made by assembly connection, welding, splicing or integrated method; During use, jig arm 214 is clamped screw rod 40, and distributing box 20 is fixed on the screw rod 40 in disassembled mode.

Shown in Fig. 2,4, the opening part of box body 21 is established a flange 215, and the side is provided with a plurality of grooves 213 that cut in advance, cuts groove 213 in advance and is circular hole by broken during use, for the fixing head of cable (Glands) 50 of different azimuth peg graft (seeing shown in Figure 10); Lid 22 is provided with a location projection 220, end in positioning convex column 220 is separated to form the jag shape with groove 221, make the positioning convex column 220 can be closely to rabbet than the flexible mode of tool in the set location hole 210 of box body 21 relative positions, lid 22 need screw promptly to be fixed on the box body 21 by this.

Establish a pit 212 at the edge of opening of box body 21 or lid 22 in addition, when opening lid 22, use finger or coin, then box body 21 and lid 22 can be separated pit 212 application of forces.

But find that in force the positioning convex column 220 of above-mentioned end jag when lid 22 lids are tight, is difficult for opening, unless pry open from pit 212 application of forces; For satisfying different owners' needs, or finish that to add screw locking lid without exception after the examination just relieved, the utility model provides another embodiment:

Shown in Fig. 5,6, in positioning convex column 220, establish a centre bore 222, in the location hole 210 of box body 21, establish an aperture 211 and insert nut 2110, after lid 22 is built, screw S1 passes centre bore 222 and aperture 211 and screws togather with nut 2110, with fixing lid 22.

As shown in Figure 7, for asking attractive in appearance, centre bore 222 porch of lid 22 are provided with flake hole 223, expose head to avoid screw S1; And cover flake hole 223 with a cover plate 224, play the preventing husky effect of dirt; Establish a groove 225 at lid 22 with respect to the flange 215 of box body 21 opening parts, place a packing ring 226 in the groove 225, when screw S1 was fastening, packing ring 226 played sealing function.

Shown in Fig. 7,8, another embodiment of the utility model, in the location hole 210 of box body 21, reserve an aperture 211; After checking and accepting, when the owner determined to add without exception the screw locking, the constructor can utilize self-tapping screw S2 to go into admittedly in the aperture 211, can play auxiliary fixing effect.

The groove 221 of positioning convex column 220 ends of the various embodiments described above can be straight flute, " ten " word ditch or " Y " type ditch (seeing shown in Figure 9), waits different jag shapes; Help to improve elasticity in a word, the location hole 210 that positioning convex column 220 and box body 21 relative positions are provided with is rabbeted easily for suitable.
