Abstract

The utility model relates to an improved structure of a screw, which is characterized in that a gasket is arranged beside a screw cap and is fixedly connected with the screw cap, the screw is not easy to loosen with the screw cap in use to cause the loosening of a to-be-fixed object due to the contact and the close contact of the gasket and the surface of the to-be-fixed object, an inner hexagonal groove is arranged on the screw cap, and the screw cap is in hexagonal design and has hexagonal design in the shape, and can be conveniently operated by using a fixed wrench or a hexagonal wrench and consists of the screw cap, the groove and the gasket; the utility model discloses its improvement structure that has an excellent screw of novelty, progressive nature and practicality.

Description

The improvement structure of screw

Technical field

The utility model relates to a kind of improvement structure of screw.

Background technique

Existing product, see also shown in Figure 1, wherein screw 1 combine with nut fixing before, need be nested with earlier a pad between nut 2 and nut in order to fixedly treating fixture, it is not one that its pad separates with nut 2, so very easily forget that because of operator's careless mistake placing pad influences the soundness that integral installation applies, under the long-term use with the vibrations for the treatment of fixture, rock combining easily of screw 1 and nut down and get loose under the careless mistake because of nothing placement pad so that influence combination, the steadiness for the treatment of fixture; And its existing nut 2 only can use fixed wrench 6 (referring to Fig. 4) to apply, and lacks multi-functional applying property.

Therefore, take a broad view of above analysis, the improvement of prior art is the place of the difficulty of the utility model designer institute utmost point desire solution.

Summary of the invention

At the deficiencies in the prior art, the purpose of this utility model is: a kind of improvement structure of screw is provided, pad is engaged with screw be one, forget the possibility that pad is installed thereby eliminate.

For achieving the above object, the technical solution adopted in the utility model is:

A kind of improvement structure of screw is characterized in that: described screw is provided with nut, and described nut and spacers binding.

The fixedly connected mode of described pad and nut is one of the forming or is welded to connect fixing.

Described nut cross section is a polygon row.

One groove is set on the described nut, and described groove cross section is a polygonal.

Described gasket surface is provided with raised line or the salient point piece that increases it and treat the frictional force between the fixture surface.

Compared with prior art, the advantage that the utlity model has is: eliminated and forgotten the possibility that pad is installed, and available multiple spanner is bestowed fastening.

Embodiment

Feature of the present utility model, purpose, effect explanation, adopt an embodiment to cooperate graphic detailed description the in detail as the back:

See also shown in Figure 2ly, the utility model is to comprise:

One screw 1, it is a body of the present utility model, support screw cap 2, pad 4, screw thread 5 are in order to making strong bonded with nut;

One nut 2, its cross section are a Hexagon, conveniently execute the author and use fixed wrench 6 rotary nuts 2, drive screw thread 5 its screw 1 is combined closely with nut;

One pad 4, it is arranged on nut 2 other is to be fixedly connected one with nut 2, its surface is provided with raised line 41 (see figure 5)s to be increased it and treats frictional force between the fixture 8 (see figure 3) surfaces;

One groove 3 is arranged on the nut 2, and its groove 3 cross sections are a Hexagon, conveniently executes the author and uses hexagon wrench's 7 (see figure 3) rotary nuts 2, drives screw thread 5 its screw 1 is combined closely with nut.

See also shown in Figure 3, it is first embodiment, utilize in the groove 3 on a hexagon wrench 7 plant nuts 2 and combine with nut with rotation mode drive screw thread 5, and utilization pad 4 with the contacting of the surface for the treatment of fixture 8, be close to down, make screw 1 be difficult for because of the vibrations for the treatment of fixture 8 in the use, rock down and nut gets loose to cause and treats that fixture 8 becomes flexible, comes off, the soundness of increase integral body.

See also shown in Figure 4, it is second embodiment, utilizing a fixed wrench 6 plant nuts 2 outer rims to sentence rotation mode drive screw thread 5 combines with nut, and utilization pad 4 with the contacting of the surface for the treatment of fixture 8, be close to down, make screw 1 be difficult for because of the vibrations for the treatment of fixture 8 in the use, rock down and nut gets loose to cause and treats that fixture 8 becomes flexible, comes off, the soundness of increase integral body.

The technical solution adopted in the utility model also has a lot of the selection, for example:

The fixedly connected mode of described pad 4 and nut 2 can be one of the forming also can be welded to connect fixing.

Described nut 2 cross sections can be a polygon row.

Groove 3 cross sections that are provided with on the described nut 2 can be a polygonal.

The increase that described pad 4 surfaces are provided with itself and treat that the also available salient point piece of the raised line 41 of the frictional force between the fixture surface replaces.

More than explanation is just illustrative for the utility model, and it is nonrestrictive, those of ordinary skills understand, under the situation of the spirit and scope that do not break away from claim and limited, can make many modifications, variation or equivalence, but but all will fall within the claim restricted portion of the present utility model.

Claims
