Description

The hinge component of AE distribution box

Technical field

This utility model relates to electric cabinet accessory structure technology, particularly relates to be applicable to the AE distribution box hinge of quick assembling Assembly.

Background technology

As shown in Figures 1 to 4: the hinge component 106 of original structure, during concrete assembling, need to pinch thread plate with the right hand 103, by box opening face 204.1, hands is stretched into the inner chamber of casing 204, with feeling to make screwed hole 103.1 and casing via 204.2 are visually directed at, and on the premise of the right hand remains stationary as, are tentatively put in casing outer rim 204.3 by free bearing 102 with left hand, And make counterbore 102.2 substantially aligned across box plate with screwed hole 103.1, now, the right hand also to remain stationary as, more successively will Cross flat head screw 104 hands is screwed into several thread of buckleing in thread plate 103, and right-hand man just can free and carry out follow-up assembling. One AE distribution box to fill two set hinge components 106 at least, many in the case of, it is identical that same AE distribution box to fill four sets Hinge component 106；It addition, after AE box door plate 201 is used the preliminary pinning of hinge pin 101 with AE casing 204, will with needle-nose pliers Split ring card 105 is clamped, and alignment exposes the cotter way 101.1 of free bearing 102, is forced in groove, because of split ring card 105 It is standard component, the thinnest and external form is the least, after installing in the most uncertain groove having snapped in hinge pin the most completely, also need to utilize needle-nose pliers Repeatedly beat.Therefore, in sum, using existing hinge component 106, efficiency of assembling is extremely low, it is impossible to meets and produces Demand, it would be highly desirable to carry out structure improvement.

Utility model content

There is, for the hinge component of existing AE distribution box, the shortcoming that efficiency of assembling is low, assembling process is loaded down with trivial details in the applicant, carries out Research and improve, it is provided that a kind of improve efficiency of assembling, reduce labor intensity, the hinge component of AE distribution box rational in infrastructure.

In order to solve the problems referred to above, this utility model following scheme of employing:

The hinge component of a kind of AE distribution box, including free bearing, hinge pin is inserted in the cover for seat pipe of free bearing, the lower surface of described free bearing Being arranged with two positioning convex, two positioning convex are corresponding with the hole, location on AE distribution box body, the portion between two positioning convex Dividing formation boss protruding upward, with counterbore on described boss, the lower surface band of boss is fluted, by spring nut, screw And free bearing is installed in the casing of AE distribution box by described counterbore, with for spring nut location peace on AE distribution box body The open slot of dress.

Further improvement as technique scheme:

The lateral symmetry of described cover for seat pipe offers dummy notch, and the dummy notch of side leaves cuts tongue, and hinge pin is placed in cover for seat pipe After, described in cut tongue correspondence and be positioned at the cotter way of hinge pin end, utilize external force to cut tongue deformation snap in described in described cotter way.

The upper surface of described spring nut is arranged with shell fragment, the end edge turned-out formation hook-shaped of described shell fragment, two shell fragments Between spring nut on the screwed hole with screw fit.

Of the present utility model have the technical effect that

This utility model arranges on free bearing positioning convex, casing arranges open slot and hole, location, spring nut can be made from casing Outside quick insertion cabinets cavity location, and location quick to free bearing, release the caused fatigue of refusing to budge of the right hand, and profit Fast Installation in screw；Dummy notch and cut the setting of tongue on free bearing so that just can get rid of traditional split ring card in general assembly, Thus simplify assembly process；In this utility model, during assembling, include location and fastening, the hinge pin of the loading of spring nut, free bearing Last pinning, whole process is simple and orderly, not only increases efficiency of assembling, and also make AE distribution box is assemblied in streamline On be possibly realized.

Detailed description of the invention

Below in conjunction with the accompanying drawings detailed description of the invention of the present utility model is described further.

The hinge component of the AE distribution box of the present embodiment, in order to alleviate the labor intensity of assembling, refusing to budge, such as Fig. 5 of the release right hand Shown in, free bearing 302 is provided with positioning convex 302.5 at two, a boss 302.3 between two positioning convex 302.5, Counterbore 302.4 is arranged on the end face of boss 302.3, and the bottom of boss 302.3 leaves groove 302.6, eliminates Fig. 1 simultaneously Middle the most irrational thread plate 103, replaces with the spring nut 303 in Fig. 5, as shown in Figure 10, spring nut 303 It is laterally inserted in box opening groove 404.3, and has the shell fragment 303.1 on the spring nut 303 of elastic deformation along assembling path 404.4 Tangle the edge of open slot 404.3 successively, so from outside, spring nut 303 is loaded the inner chamber of AE distribution box body 404 In；As shown in Figure 10, provide convenience for the quickly location of free bearing 302 in Fig. 5 in hole, casing location 404.2；If Fig. 7 is to figure Shown in 9, then with cross flat head screw 304 by the counterbore 302.4 on boss 302.3, with spring nut 303 at AE case The inner chamber of body 404 engages, completes location and the fastening of free bearing 302；As shown in Figure 6, cover for seat pipe 302.1 is arranged with Dummy notch 302.7 and leave and cut tongue 302.2, the setting of dummy notch 302.7 its objective is to abandon Fig. 1 and Fig. 2 in general assembly In split ring card 105, simultaneously for needle-nose pliers clamping cut tongue 302.2 slot milling；Tongue 302.2 is cut also with needle-nose pliers clamping It is allowed to deform, embeds the cotter way 301.1 in Fig. 6, thus pin hinge pin 301, complete hinge component efficiently at AE distribution box In general assembly.

Embodiment provided above is better embodiment of the present utility model, is only used for convenient explanation this utility model, not to this Utility model makees any pro forma restriction, has usually intellectual in any art, if new without departing from this practicality In the range of the carried technical characteristic of type, the equivalence utilizing the done local of this utility model disclosed technology content to change or modify is real Execute example, and without departing from technical characteristic content of the present utility model, all still fall within the range of this utility model technical characteristic.
