Embodiment
Need to prove that in the situation of not conflicting, embodiment and the feature among the embodiment among the application can make up mutually.Below in conjunction with accompanying drawing the utility model is described further.
As shown in Figure 1 to Figure 3, the utility model embodiment's box body connector comprises land 10, screw 20 and some casings 30, and land 10 is fixed on casing 30 surfaces by screw 20, and then casing 30 is linked together.
As described in Figure 1, land 10 is thin-slab structure, take land 10 applying casings 30 surfaces as the bottom surface, deviate from casing 30 surfaces as end face as directional reference, land 10 end faces are to having through hole 11, mutually screw togather with following tapped hole 31 after passing for screw 20.Among the embodiment such as Fig. 1, this through hole 11 is divided into the straight hole section 13 that contains stepped part 12 and the horn-like reaming section 14 of mutual linking, and straight hole section 13 inwalls are provided with internal thread.Vertical described land 10 end faces extend upward and form hollow column 15, hollow column 15 connects with described through hole 11 and forms described straight hole section 13, in the present embodiment, hollow column 15 cross sections are circular, certainly, also can be other polygonal shapes, for example, square, regular hexagon etc., the internal diameter of hollow column 15 is greater than or equal to the diameter of straight hole section 13, and so, the tapped hole 31 that screw 20 can pass on through hole 11 and the casing 30 screws togather, simultaneously hollow column 15 plays leading role, so that screw 20 rotations depart from the amplitude of fluctuation of axial direction when installing is little.Be provided with stiffening rib 16 between hollow column 15 outer walls and land 10 surfaces, make land 10 structures more firm, the damage of opposing external force.As shown in Figure 2, described land 10 is provided with positioning hole 17, positioning hole 17 can be the through hole that the cross section is rectangle, also can be that the cross section is fan-shaped through hole, certainly, the through hole that the cross section is any shape can be used in the land 10 of the present invention, positioning hole 17 and casing 30 edge-adjacent corresponding matching, positioning hole 17 is used for observing casing 30 when piecing together, and whether the edge between the casing 30 satisfactory linking together, and is convenient to the accurate location that casing 30 connects.Land 10 is provided with two and grips breach 18, and its symmetry is laid on the edge of land 10, but single-hand handling ﹠ was taken land 10 when finger snapped in gripping breach 18, the convenient installation.
Such as Fig. 1, shown in Figure 2, thereby the precession end 21 of screw 20 is provided with highly less boss 22 and forms step surface 24 at screw rod 23, boss 22 be provided with straight hole section 13 in the outside thread of screw-internal thread fit, precession end 21 is by in described, the outside thread cooperation is passed straight hole section 13 and is imported in the described horn-like reaming section 14, at this moment, step surface 24 and stepped part 12 mutual butts, prevent that screw 20 breaks away from land 10, the length of reaming section 14 is greater than or equal to the length of boss 22, like this, when the precession end 21 of screw 20 withdraws from following tapped hole 31, precession end 21 can be contained in the reaming section 14, avoid because of step surface 24 and stepped part 12 mutual butts so that precession end 21 forms projection in the land bottom surface, when land 10 links together many casings 30, avoid projection and casing 30 to conflict, so, land 10 bottom surfaces can be fitted on the surface of casing 30 fully, improve the Location accuracy between land 10 and the casing 30.
The utility model embodiment's casing connected system comprises described box body connector and some casings 30, and described connection set removably is spliced into one with described casing 30.
As shown in Figure 3, the quantity of casing 30 is 4 in the present embodiment, and it is the square structure, casing 30 is provided with projection 32, and projection 32 end faces smooth and its shape and land 10 bottom surfaces coupling preferably are set at the angle, so, projection 32 end faces can fit tightly with the flat bottom surface of land 10.Be provided with the tapped hole 31 that cooperates with outside thread on described screw 20 boss 22 in the projection 32, casing 30 is gapless piecing together in same plane each other,, the precession end 21 of box body connector by described screw 20 passes described through hole 11 and screws togather with tapped hole 31 and be fixed on the described casing 30.
The above is embodiment of the present utility model; should be pointed out that for those skilled in the art, under the prerequisite that does not break away from the utility model principle; can also make some improvements and modifications, these improvements and modifications also are considered as protection domain of the present utility model.
