Abstract

The utility model relates to an antirust screw. The antirust screw is used for solving the problems that the present screw after being rusted cannot be detached and the resources are seriously wasted. According to a method for solving the problems, an original nut is cut into two halves and a polygonal circular block is used for wrapping the periphery, so that the nut which is cut into two halves can be fixed and a stress point for a wrench is supplied. When the screw is rusted and cannot be opened by using the wrench, the nut can be knocked by using an article, such as a hammer, so that the outer circle is naturally separated from the two halves of the nut.

Description

A kind of antirust screw

Technical field

A kind of antirust screw is used for the screw field of outdoor installation, is particularly useful for extended immobilization, but but is exposed to the screw field in the severse weather environment.

Background technique

Present screw, material itself are that metal is processed, thus be easy to get rusty, the screw in the aerial severse weather environment of long term exposure particularly, as: air-conditioning, electric wire etc.

Existing technology formalizes the structure of screw itself for the shape of screw; Be made up of the axle of the band twill of centre and the inboard streaky polygon structure of outside, this technology is fixed for screw, no doubt is extraordinary; But because the installation of equipment component needs long term exposure in air, like the outer machine of air-conditioning; Must be installed in the open air, and cannot keep out wind and rain in the open air, so after long-term exposing to the sun and rain; The surface of screw is easy to just get rusty, if this serious the arriving to a certain degree of getting rusty will be embroidered nut extremely fully; In case when having one machine needs dismounting beyond the highest heavens, the dead screw of this embroidery has caused very big trouble for workman's dismounting when having lost value; Can't directly back out because embroider dead screw, the way of employing has only with the hacksaw axle cut-out fully that screw is middle, and is perhaps that whole screw structural is discarded fully.

Because the axle in the screw has inserted in the middle of the wall fully, this discarded for attractive in appearance, secure context is all bad.If solve the problem of rustiness of screw fully, existing technology is through improving the material of screw, perhaps periodic maintenance, but this way takes time and effort itself, is again a kind of waste for resource.

Summary of the invention

The present invention provides a kind of antirust screw, is used to solve promptly can't take the serious waste problem of resource apart after in a single day existing screw gets rusty.

The way that the present invention adopts is: original nut is cut into two halves; The periphery is surrounded with a polygonal circle piece again; Make three whole shapes that consist of a nut of part; But bonding without other technologies again between the three, except can fixing nut in two, also can let spanner find force bearing point like this.Between screw piece and the outer ring, except direction shown in the screw shaft, other directions all cannot relatively move, so three and screw shaft can keep fixing for a long time.When screw has got rusty when can't open with spanner, can laterally knock nut with objects such as hammers, let outer ring and two half-nuts naturally separately.This way can also increase substantially the installation efficiency of nut except the drawback of " be not afraid of embroider dead " of having solved screw, because nut screwing clamping at ordinary times the time; Need nut be placed on the outer end of screw shaft; Constantly rotate until rotating to the summit with spanner then, and screw provided by the invention can directly be enclosed within subapical position with the two halves screw earlier in the time of installation; And then be inserted in the outer ring from outer rim, directly tighten at last.

Screw adopts after the structure of the present invention; Even if long-time severse weather influence causes the screw rust dead, also need not whole screw is all amputated, even adopt the mode of other sudden huge profits that screw is destroyed; Only need the shell of this screw directly be knocked out and get final product, greatly facilitate installation.

Description of drawings

Accompanying drawing is a front view of the present invention.

Embodiment

In Fig. 1, nut block 101 is two half-nuts that can be combined into nut shape with nut block 102, between the two not welding; Can arbitrarily separate and amalgamation, but cannot directly connect, outer ring 201 is a polygonal ring structure; Polygonal inboard and nut block 101 and nut block 102 can mesh; Nut block 101 can be positioned over the inboard, outer ring in position as shown in the figure with nut block 102, after nut block 101 and nut block 102 placements as shown in the figure, connects between the nut block; If get up three unit constructions this moment, the shape that is a nut is enclosed within above the screw shaft 301.

When nut need be tightened, only need nut block 101 and nut block 102 be positioned near the summit, the both sides from screw shaft piece together then; Move along screw shaft 201 of outer rings; Until arriving the position shown in the figure, when the three formed a nut shape, screwing up with a wrench got final product again.

Claims (1)

1. an antirust screw has structures such as nut, screw shaft, can object be fixed in certain position; It is characterized in that: original nut is cut into two halves; The periphery is surrounded with a polygonal circle piece again, makes three whole shapes that consist of a nut of part, is enclosed within on the screw shaft.
