Abstract

The utility model discloses a nut, which resolves the problems that because the existing nuts are pulled out from plastic shells frequently, the plastic shells are easy to be damaged and electronic products are easy to be damaged. The nut comprises a columnar nut body and an axial screw hole, wherein at least one groove is arranged on an outer side ring of the nut body. When the nut and a plastic shell are molded via injection together, plastic is absorbed to the groove of the nut; after molding, the nut and the plastic shell are combined tightly, a contact surface between the nut and the plastic shell is enlarged due to the groove arranged on the outer surface of the nut, and the nut can bear higher tension and can not be separated from the plastic shell, thereby achieving firmer connection. Further, most portions of the nut are made of metal, and the groove of the nut saves usage of metal materials, thereby saving cost. Therefore, the nut is simple in structure and firmer in combination and saves cost.

Description

Nut

Technical field

The utility model relates to a kind of link, relates in particular to a kind of nut.

Background technique

Existing nut generally includes nut body that is column structure and the screw that axially is provided with, and is provided with screw thread in the screw.Plastic shell at some electronic products adds man-hour, and with shell injection moulding processing, the surface of contact of nut and plastic shell is the outer surface of nut to nut usually, yet the pulling force that outer surface bore of existing nut is little.When pulling force was big, nut was usually pulled out from plastic shell, caused shell to damage, and did not reach the effect of covering protection, and then electronic product is damaged.

In summary, existing nut obviously exists inconvenience and defective on reality is used, so be necessary to be improved.

The model utility content

At above-mentioned defective, the purpose of this utility model is to provide a kind of nut, and it is simple in structure, in conjunction with more firm, and saves cost.

To achieve these goals, the utility model provides a kind of nut, comprises nut body that is column structure and the screw that axially is provided with, and the outer ring of described nut body is provided with at least one groove.

According to nut of the present utility model, the outer surface of described nut body is axially arranged with a plurality of equally distributed teeth.

According to nut of the present utility model, the cross section of described tooth is a triangle.

According to nut of the present utility model, described groove is circular.

According to nut of the present utility model, described nut is the LED display nut, and some described LED display nuts are affixed with LED display drain pan and LED display casing.

According to nut of the present utility model, described LED nut is a metal nuts.

The utility model is by by establishing at least one groove at the outer ring of nut body, when nut during with the plastic shell injection moulding, plastic cement will be adsorbed on the groove of nut, after the moulding, nut will with plastic shell combining tightly because the outer surface of nut has groove, the surface of contact of nut and plastic shell is bigger, nut can bear bigger pulling force, and does not deviate from from plastic shell, thereby more firm; Nut is made of metal mostly, and the groove of nut of the present utility model has been saved the use of metallic material, provides cost savings.Whereby, the utility model is simple in structure, in conjunction with more firm, and saves cost.

Preferably, the outer surface of nut body is axially arranged with a plurality of teeth, has further increased the surface of contact of nut and plastic shell, and is more firm.

Embodiment

In order to make the purpose of this utility model, technological scheme and advantage clearer,, the utility model is further elaborated below in conjunction with drawings and Examples.Should be appreciated that specific embodiment described herein only in order to explanation the utility model, and be not used in qualification the utility model.

As Fig. 1～shown in Figure 5, a kind of nut 100 of the utility model comprises nut body 10 that is column structure and the screw 20 that axially is provided with, and the outer ring of nut body 10 is provided with at least one groove 30.Groove 30 is preferably to circular, and obviously groove 30 also can be for other shapes, as helical.Nut 100 is a metal nuts, is preferably copper or stainless steel.

When nut 100 during with the plastic shell injection moulding, plastic cement will be adsorbed on groove 30 places of nut 100, after the moulding, nut 100 will with plastic shell combining tightly, and because the outer surface of nut 100 has groove 30, nut 100 is bigger with the surface of contact of plastic shell, and nut 100 can bear bigger pulling force, and it is from plastic shell, do not deviate from, thereby more firm; Nut 100 is made of metal mostly, and the groove 30 of nut 100 of the present utility model has been saved the use of metallic material, provides cost savings.Whereby, the utility model is simple in structure, and is fixing more firm, and saves cost.

As Fig. 2, Fig. 3 and shown in Figure 4, the outer surface of nut body 10 is axially arranged with a plurality of equally distributed teeth 40.The cross section of tooth 40 is preferably triangle.Obviously, tooth 40 cross section be not limited only to triangle, can be rectangle, semicircle etc.A plurality of equally distributed teeth 40 have further increased the surface of contact of nut 100 and plastic shell, thus make between nut 100 and the plastic shell combine more firm.

As Fig. 5, Fig. 6 and shown in Figure 7, nut 100 is the LED display nut, some LED display nuts 100 are affixed with LED display drain pan 200 and LED display casing 300, effectively LED display drain pan 200, waterproof apron 400 and LED display casing 300 are linked together by screw, form the LED display module.LED display nut 100 is preferably metal nuts, generally adopts copper nut.

In the present embodiment, this LED display nut 100 is processed with 200 injection mouldings of LED display drain pan, LED display nut 100 has groove 30, it increases with the adsorption plane that contacts of LED display drain pan 200, plastic cement adsorbs into groove 30, and be snapped on the LED display nut 100, after tested after, the pulling force that LED display nut 100 can bear reaches more than the 50kg/N.Further, as shown in Figure 7, the outer surface of LED display nut 100 also is axially arranged with a plurality of equally distributed teeth 40, a plurality of teeth 40 have further increased the area of contact of LED display nut 100 with LED display drain pan 200, make LED display nut 100 and LED display drain pan 200 more effective combining.

In sum, the utility model is by by establishing at least one groove at the outer ring of nut body, when nut during with the plastic shell injection moulding, plastic cement will be adsorbed on the groove of nut, after the moulding, nut will with plastic shell combining tightly, because the outer surface of nut has groove, the surface of contact of nut and plastic shell is bigger, and nut can bear bigger pulling force, and it is from plastic shell, do not deviate from, thereby more firm; Nut is made of metal mostly, and the groove of nut of the present utility model has been saved the use of metallic material, provides cost savings.Whereby, the utility model is simple in structure, in conjunction with more firm, and saves cost.

Certainly; the utility model also can have other various embodiments; under the situation that does not deviate from the utility model spirit and essence thereof; those of ordinary skill in the art work as can make various corresponding changes and distortion according to the utility model, but these corresponding changes and distortion all should belong to the protection domain of the appended claim of the utility model.
