Abstract

The utility model relates to a nut, axially comprising an upper segment, a middle segment and a lower segment, wherein, the upper segment is projected outward corresponding to the middle segment, and the upper segment and the middle segment are respectively provided with a pulling-drawing shape outer periphery gradually expanding and attacking toward to the direction of the lower segment. The gradient of the pulling-drawing shape outer periphery of the upper segment is bigger than the gradient of the pulling-drawing shape outer periphery of the middle segment.

Description

Nut

The utility model is about a kind of nut, more detailed it, particularly can directly be installed on the nut that does not need any auxiliary fixing member on the machine case about a kind of.

With present widely popular electronic dictionary is example, its framework is for fixing circuit board, panel, Deng member and need to use some bolts, bolt is that rigid material is made because framework is made by plastic material, if on framework directly tapping then its screw thread be easy to be worn and torn and lock bolt again by bolt, so generally not direct thereon tapping, but perforation is set on framework, with screw cap imbedded in it, again bolt is locked nut, because nut is along the identical diameter of its axial tool, so may the perforation on framework drop out, need to paste to prevent screw cap-falling, rather complicated inconvenience on working process with adhesive tab in the bottom of perforation.

In view of this, the inventor researchs and develops nut successfully of the present utility model finally through thinking hard funiculus, studying intensively, and can be convenient for assembly, enhances productivity.

Therefore, main purpose of the present utility model is to provide a kind of nut, can be in the perforation of directly inserting on the machine case and without any need for auxiliary fixing device.

Another purpose of the present utility model is the nut that a kind of easy installation is provided and can not drops.

For achieving the above object, nut of the present utility model, typically be a kind of hexagon nut, axially comprise epimere, stage casing and hypomere, wherein relative this stage casing with hypomere of this epimere is outwards outstanding, and each tool one of this epimere and this stage casing pulls out outer circumferential face towards pushing away of expanding gradually of this hypomere direction, and the slope of the pushing and drawing shape outer circumferential face of this epimere is greater than the pushing and drawing shape outer circumferential face slope in this stage casing.

Now cooperate figure is described as follows preferred embodiment of the present utility model, believe other purposes of the present utility model, feature and advantage all can by and more deep concrete understanding.

Fig. 1 is the top view according to an embodiment of the present utility model;

Fig. 2 is the side view according to an embodiment of the present utility model;

Fig. 3 is the bottom view according to an embodiment of the present utility model; And

Fig. 4 is the user mode schematic representation according to an embodiment of the present utility model.

Consult Fig. 1 to Fig. 3, one screw 100 is arranged in the middle of the nut of a preferred embodiment of the present utility model, face can be divided into epimere 10, stage casing 20 and hypomere 30 by top to bottom around it, its epimere 10 and hypomere 30 diametrically all than stage casing 20 for outstanding form stepped, as seen from the figure, epimere 10 all has a pushing face-drawing with stage casing 20, and promptly its diameter increases gradually towards hypomere 30, and the pushing face-drawing slope in the slope ratio stage casing 20 of the pushing face-drawing of epimere 10 is big.

Referring to shown in Figure 4, when being installed, this nut set perforation 200 bottoms on the electronic dictionary framework for example, its top can be pushed, this perforation 200 also can be divided into three sections from top to bottom, promptly, see it by its cross section, the wideest hypomere, inferior wide epimere and the narrowest stage casing, the wall in its stage casing has a pushing face-drawing that cooperates the slope in nut stage casing 20, and the width of its lower edge equates with epimere the widest position of nut approximately so that the inserting of nut.After pushing nut, the root edge of nut epimere 10 is stuck in the epimere place of perforation, and the hypomere of nut is placed in the hypomere of perforation and locate, so promptly can not drop out after screw cap imbedded by the two ends of perforation 200, therefore, need not blockade the bottom of nut in case drop with adhesive tab as conventional art.

The advantage of nut of the present utility model is:

1. must not use other assistant tool can assemble.

2. improve the convenience of part assembling, enhance productivity.

In sum, nut of the present utility model, really the above-mentioned disclosed structure of energy mat reduces and makes in the assembly process, and therefore the trouble of nut location can improve its manufacturing efficiency

But the description of drawings that above-mentioned the utility model discloses only is embodiment of the present utility model, is familiar with this case skill people bodyguard generally, and its institute is according to the application's spirit category, and the equivalence of being done changes or modifies, and all should be encompassed in the appended claims restricted portion.

Claims

1. a nut is characterized in that, axially comprises epimere, stage casing and hypomere, and wherein relative this stage casing with hypomere of this epimere is outwards outstanding, and the pushing and drawing shape outer circumferential face expanded gradually towards this hypomere direction of this epimere and each tool one of this stage casing.

2. nut as claimed in claim 1 is characterized in that, the slope of the pushing and drawing shape outer circumferential face of this epimere is greater than the pushing and drawing shape outer circumferential face slope in this stage casing.

3. nut as claimed in claim 1 or 2 is characterized in that, the hypomere of this nut is a hexagon.
