Abstract

The utility model provides a kind of torsion screw safety protection cap, comprises cap body, and a side on cap body is longitudinally provided with otch, another side non-incision relative with above-mentioned side, is provided with for spacing chamfering protruding at the open-mouth of cap body.The safety protection cap that the utility model provides can be enclosed within the plane of rupture of torsion screw rapidly, avoids the generation of fracture surface scratching fingers situation; In addition the protruding swells being connected to torsion screw of chamfering prevents safety protection cap to be pulled out easily, ensure that the stability that safety protection cap is connected with torsion screw swells.

Description

Torsion screw safety protection cap

Technical field

The utility model relates to a kind of torsion screw safety protection cap.

Background technique

Torsion screw is followed successively by the fastening head of hexagonal, broken part, swells, screw section from top to bottom, and the torsion of this kind of screw is setting, and when the fastening head of hexagonal reaches setting torsion, rupture in broken part, the fastening head of hexagonal departs from from torsion screw.

Adopt the benefit of this kind of torsion screw: one is to make the stressed equalization of all torsion screws; Two is after the fastening head of hexagonal fractures, and people are difficult to operate screw again, thus maintain the stability of connected element.

But, existing torsion screw Shortcomings part in use: the fastening head of hexagonal just produces fracture because broken part produces flow of metal, and therefore post-rift broken part exists sharp bristle thorn, has the danger of scratching fingers.

Model utility content

For above deficiency, the utility model provides a kind of torsion screw safety protection cap, for the protection of the fracture surface of torsion screw, easy for installation, difficult drop-off.

The technical solution of the utility model: torsion screw safety protection cap, comprises cap body, a side on cap body is longitudinally provided with otch, another side non-incision relative with above-mentioned side, is provided with for spacing chamfering protruding at the open-mouth of cap body.

The sidewall not uniform thickness of described cap body, thickeies the sidewall being provided with otch, does like this and can prevent cap body deformability on the one hand, can prevent cap body from coming off on the other hand.

The chamfering projection of cap body open-mouth does not wait large, and comparatively large with the chamfering projection of otch side, the chamfering projection of non-incision side is less, can make quick and easy for installation like this, cap body can be avoided again to occur the situation of coming off simultaneously.

The beneficial effects of the utility model: the safety protection cap that the utility model provides can be enclosed within the plane of rupture of torsion screw rapidly, avoids the generation of fracture surface scratching fingers situation; In addition the protruding swells being connected to torsion screw of chamfering prevents safety protection cap to be pulled out easily, ensure that the stability that safety protection cap is connected with torsion screw swells.

Embodiment

As shown in Figures 2 to 6, torsion screw safety protection cap, comprises cap body 1, and a side on cap body 1 is longitudinally provided with otch 2, and another side non-incision relative with above-mentioned side, is provided with for spacing chamfering projection 3 at the open-mouth of cap body 1.The sidewall not uniform thickness of described cap body 1, thickeies the sidewall being provided with otch 2.The chamfering projection 3 of cap body 1 open-mouth does not wait large, and comparatively large with the chamfering projection 3 of otch 2 side, the chamfering projection 3 of non-incision side is less.

The utility model because very little, so be designed to multiple linking together, as shown in Figure 9, with the little loss of preventing member when being shaped.Adopt above-mentioned Placement, torsion screw safety protection cap can easily disconnect again after mounting.
