Summary of the invention

The purpose of the utility model is the anti-misoperation drawer structure that a kind of low-tension switch cabinet is provided in order to address the above problem, and it can guarantee that the drawer body can not insert non-corresponding loop compartment.

For realizing above-mentioned purpose; The anti-misoperation drawer structure of the low-tension switch cabinet of the utility model comprises a plurality of loops compartment; Each loop compartment corresponding matching is equipped with a movable drawer body of pulling out or pushing; In the drawer body electric components is installed, shape, the specification of each drawer body are identical, and the shape of each loop compartment, specification are also identical; Each loop compartment is provided with horizontal laminate and vertical dividing plate; Each drawer body is provided with drawer-bottom board; Its main feature is; The horizontal laminate of each loop compartment all is fixed with several identification posts protruding upward, and the drawer-bottom board of each drawer body all is fixed with several identification blocks of protrusion downwards; The identification post of each loop compartment meets following matching relationship with the identification block of corresponding drawer body: all identification blocks of drawer body and all of loop compartment identification post all stagger mutually on the lateral attitude; The identification post of each loop compartment meets following matching relationship with the identification block of non-corresponding drawer body: the drawer body has at least at least one identification post of an identification block and loop compartment overlapping on the lateral attitude.

Vertically so-called, be exactly the direction that the loop compartment was extracted or pushed to drawer out.Laterally so-called, be exactly and vertical vertical horizontal direction.

The utlity model has following advantage and effect:

1, correctly inserts in the corresponding loop compartment when the drawer body,, so can push smoothly because all identification posts of all identification blocks of this drawer body and this loop compartment all stagger mutually on the lateral attitude; But when the drawer body misplugs in the loop compartment of a certain non-correspondence; Then because this drawer body has at least at least one identification post of an identification block and this loop compartment overlapping on the lateral attitude; So the identification block of drawer body can be blocked by the identification post of loop compartment; Therefore can not push smoothly; So just can make drawer body and loop compartment set up matching relationship one to one, effectively avoid the drawer of same size to obscure, guaranteeing not can misoperation and the drawer body pushed the loop compartment of non-correspondence.

2, the horizontal level of identification post and identification block is clocklike and distributes, and forms some strong points, is playing outside its fool proof function, also plays the weight of bearing the drawer body and the effect of external force.

Description of drawings

Fig. 1 is the identification block of the utility model specific embodiment drawer body and the identification post lateral attitude matching relationship sketch map of the horizontal laminate of loop compartment.

Fig. 2 is the assembled state sketch map of structure shown in Figure 1.

Embodiment

The anti-misoperation drawer structure of Fig. 1, Fig. 2, low-tension switch cabinet comprises five loop compartments; Each loop compartment corresponding matching is equipped with a movable drawer body 4 of pulling out or pushing; In each drawer body 4 electric components is installed, each loop compartment 3 is provided with horizontal laminate 1 and vertical dividing plate, and each drawer body 4 is provided with drawer-bottom board 2; Shape, the specification of each drawer body are identical, and the shape of each loop compartment 3, specification are also identical.

The horizontal laminate 1 of each loop compartment 3 all is fixed with four identification posts 11 protruding upward, and the drawer-bottom board 2 of each drawer body 4 all is fixed with six identification blocks 21 of protrusion downwards; Mechanical coding is carried out through the mode of permutations and combinations in the lateral attitude of each drawer body identification block and each loop compartment identification post; Mechanical coding is according to following principle: " if the drawer body constitutes corresponding relation with the loop compartment, then identification block with discern post and on the lateral coordinates position, dodge mutually; If it is drawer body and loop compartment do not constitute corresponding relation, overlapping on then at least one identification block and the identification post lateral coordinates position ".Like this, the identification post 11 of each loop compartment meets following matching relationship with the identification block 21 of corresponding drawer body: all identification blocks 21 of drawer body all stagger mutually on the lateral attitude with all identification posts 11 of loop compartment.The identification post 11 of each loop compartment meets following matching relationship with the identification block 21 of non-corresponding drawer body: the drawer body has at least an identification block 21 overlapping on the lateral attitude with at least one identification post 11 of loop compartment.Therefore, have only under the drawer body situation corresponding, could the drawer body be pushed the loop compartment with the loop compartment.

Specifically, see that each drawer-bottom board has A among Fig. 1, B, C, D, E, F, G, H, I, ten positions of J respectively from the lateral attitude; The horizontal laminate of each loop compartment has a among Fig. 1, Fig. 2, b, c, d, e, f, g, h, i, ten correspondence positions of j respectively; Wherein A is identical with the lateral coordinates position of a, and B is identical with the lateral coordinates position of b, so analogizes, and J is identical with the lateral coordinates position of j.Fig. 1, shown in Figure 2; The drawer-bottom board 2 of first drawer body is equipped with the identification block 21 of downward protrusion in A, C, E, F, H, six positions of J, the horizontal laminate b of first loop compartment, d, g, four positions of i are equipped with four identification posts 11 protruding upward; Like this; First drawer body forms corresponding relation with first loop compartment; All identification blocks of this drawer body and all of this loop compartment identification post all stagger mutually on the lateral attitude, so first drawer body can push first loop compartment smoothly.

Second loop compartment is separately installed with an identification post protruding upward at horizontal laminate in a, d, g, i position; The 3rd loop compartment is separately installed with an identification post protruding upward at horizontal laminate in c, d, g, i position; The 4th loop compartment is separately installed with an identification post protruding upward at horizontal laminate in e, d, g, i position; The 5th loop compartment is separately installed with an identification post protruding upward at horizontal laminate in f, d, g, i position; Therefore, first drawer body can not be pushed into second, third, in the 4th, the 5th loop compartment.The matching relationship of all the other each drawer bodies and each loop compartment and first drawer body 4 are roughly the same.

Shown in Figure 2, after drawer body 4 was advanced to loop compartment 3, identification post 11 formed the strong point in drawer bottom, is playing outside its fool proof function, also played the effect of the weight of bearing drawer body 4 and external force, resistance to deformation.
