Abstract

An improved retaining nut relates to a fixing part. The retaining nut comprises a cylindrical body, wherein a single circle of internal screw teeth less than one circle is manufactured on the inner wall of the body, and is arranged on the inner wall of one end of the body, an opening is opened on one end of the body, and one side of the opening is used as the starting point of the single circle of internal screw teeth less than one circle, and the end point of the single circle of internal screw teeth less than one circle does not exceed the other side of the opening or the extended line of the screw teeth on the inner wall, and the single circle of internal screw teeth less than one circle is formed in one time by punching and twisting the metal body through relevant dies. The improved retaining nut can save energy and reduce consumption during the processing as the retaining nut is punched and twisted by the relevant dies, is formed in one time, and does not need the pressing which wastes labor and time, the weight is light, and rare non-renewable metal resources can be saved, the installation is convenient, safety can be increased, the applicability is excellent, and the usage is wide.

Description

A kind of set screw nut of improvement

Technical field

The utility model relates to a kind of fixed block, especially a kind of set screw nut.

Background technique

Set screw nut is the requisite fixed block of various electrical equipment, as switch etc. being fixed in lamp socket etc., usually with the nut part that fixes, by nut and the double-screw bolt that cooperates with it switch etc. is fixed in lamp socket, fan etc.

Traditional set screw nut profile is generally hexahedron, is convenient to cooperate with fastening instrument; Its inwall has been attacked thread, is called internal thread (internal screw thread).In the prior art, the internal thread of set screw nut is the multi-turn shape, comprises the internal screw thread of continuous multi-turn.Generally by lathe car system, operation is numerous and diverse in the making of internal thread, and it is consuming time to take a lot of work, and a slight set screw nut, the time cost of its making are but very high.

The competition in market is growing more intense, and satisfying and guaranteeing to reduce production costs under the situation of product performance as far as possible, be the needs that improve product market competitiveness.Reduce production costs and need make great efforts in all its bearings, comprising its each processing technology of components, that is a slight set screw nut I guess.The processing technology of set screw nut is simple, and the energy consumption of processing and man-hour will reduce, and its cost of production falls thereupon.Be simplified to fix the processing technology of nut, one of its approach is a structural design of improving set screw nut under the situation of constant intensity satisfying, and employing can reduce the new-type structure in power consumption of polymer processing and man-hour.

A kind of easy to process, set screw nut that can reduce the new-type structure in power consumption of polymer processing and man-hour of market demand, lower to reduce production costs, strengthen its market competitiveness.

The model utility content

The utility model is intended to the above-mentioned deficiency and the market demand at prior art, releases a kind of set screw nut of improvement, and it is easy to process, can reduce power consumption of polymer processing and man-hour, and its every technical performance meets the demands in the same old way.

For this reason, the set screw nut of a kind of improvement of the utility model adopts following technological scheme:

The set screw nut of structure the utility model a kind of improvement comprises the body of tubular, makes individual pen internal screw thread less than a border at the inwall of described body, less than the described internal screw thread of the individual pen of border shape in the shape of a spiral.

Technique scheme is further set forth:

Be produced on the inwall of the termination of described body one end less than the described internal screw thread of the individual pen of a border.

Open system one opening in the termination of described body one end, one side less than the described internal screw thread of the individual pen of a border with described opening be starting point, be no more than another side or its elongation line of described opening at inwall less than the terminal point of the described internal screw thread of individual pen of a border.

Turn round system by corresponding die stamping, single forming less than the described internal screw thread of the individual pen of a border by the described body of metal.

The profile of described body is six bar shapes or cylindrical shape.During the hand nutting, can increase frictional force, strengthen feel, twist and revolve appropriateness.

The utility model is compared with prior art, its beneficial effect is: energy-saving and cost-reducing in one, the processing, because described internal screw thread of the present utility model less than a border, is the individual pen shape, and is positioned at the termination of body one end, therefore can turn round system by corresponding die stamping, single forming, the car system when no longer needing to consume expenses of labour, manpower expends in the time of not only can alleviating making, reduce labor intensity, also can energy efficient; Nut wall of the present utility model is thinner, and it is light that its weight is wanted, and can also save valuable non-renewable metals resources.Two,, can also alleviate the weight of product, improve Security because weight saving not only is convenient to install.As wherein there being a kind of switch to be used on the pendent lamp, and this switch is fixed in ceiling fan with the utility model, therefore, the utility model of lightweight has alleviated the weight load of this ceiling fan, in other words, increased the Security of using, know that it is a kind of fatefulue danger that ceiling fan drops from the ceiling board of being fixed.Its three, suitability is good, be convenient to cooperate with double-screw bolt, thereby, of many uses, be applicable to multiple occasion.

Embodiment

Below, in conjunction with the accompanying drawings, introduce embodiment of the present utility model.

Shown in Fig. 1,2,3,4, the set screw nut of a kind of improvement of the utility model comprises the body 1 of tubular, makes individual pen internal screw thread 2 less than a border at the inwall of described body 1, less than the described internal screw thread 2 of the individual pen of border shape in the shape of a spiral.

Be produced on the inwall of the termination of described body 1 one ends less than the described internal screw thread 2 of the individual pen of a border.

Open system one opening 3 in the termination of described body 1 one ends, is starting point less than the described internal screw thread 2 of the individual pen of a border with one side a of described opening 3, is no more than another side b or its elongation line at inwall of described opening 3 less than the terminal point of the described internal screw thread 2 of the individual pen of a border.

Turn round system by corresponding die stamping, single forming less than the described internal screw thread 2 of the individual pen of a border by the described body 1 of metal.

The profile of described body 1 is six bar shapes or cylindrical shape.During the hand nutting, can increase frictional force, strengthen feel, twist and revolve appropriateness.

As shown in Figure 5, when the utility model uses, will pass the fixed hole of assembling set to be fixed (as switch), and with hand the utility model will be screwed into double-screw bolt and tighten and get final product as the double-screw bolt on the lamp socket 4.
