Abstract

The utility model relates to a screw bolt positioning device, in particular to a screw bolt anti-rotating positioning device which can prevent a screw bolt from rotating. The utility model provides the screw bolt anti-rotating positioning device which can prevent the screw bolt from rotating together when carrying out tightening operation to a screw nut. The screw bolt anti-rotating positioning device comprises the screw bolt, the screw bolt comprises a screw bolt head (1) and a screw bolt body (2), and the screw bolt anti-rotating positioning device is characterized in that a branch plate (3) matched with the screw bolt to be used is also included; the branch plate (3) comprises a branch plate groove (4) and a branch plate hole (5); the screw bolt body (2) passes through the branch plate hole (5); the screw bolt head (1) is in transition fit with the branch plate groove (4) in the groove (4). Because the screw bolt head is clamped in the groove, when the screw nut is rotated, the screw bolt head can not follow with the screw nut to rotate because of the limit of the groove, therefore, the space to which the screw bolt head is faced and in which the screw bolt head is positioned is narrowed or buried, the tightening operation from the screw bolt head is not easy to be carried out and the convenience is enhanced.

Description

The bolt anti-rotation positioning device
Technical field
The utility model relates to a kind of bolt positioning device, relates in particular to a kind of bolt anti-rotation positioning device that prevents that bolt from rotating.
Technical background
In daily production, life, often the catotropic bolt of bolt need be carried out fasteningly, when the residing space of bolt head is narrow and small or buried, can only tighten operation, but this moment, bolt can rotate and then to nut, also just can't step up to operate.
The model utility content
The utility model is at above problem, provides a kind of when nut is tightened operation, prevents the bolt anti-rotation positioning device that bolt rotates together
The utility model comprises bolt, and bolt comprises the bolt head 1 and the body of bolt 2, it is characterized in that: also comprise the support plate 3 that uses with bolt matching.Support plate 3 comprises a support plate groove 4 and a plate hole 5, and the body of bolt 2 passes a plate hole 5, and bolt head 1 forms transition fit with support plate groove 4 in groove 4.
Because bolt head is stuck in the groove, when nut was rotated, bolt head was subjected to the restriction of groove and can follow nut to rotate together, thus to bolt head down and the residing space of bolt head narrow and small or buried, difficult situation of stepping up to operate from bolt head has improved facility.
Description of drawings
Fig. 1 is a structural representation of the present utility model;
Fig. 2 is a user mode side diagrammatic sketch of the present utility model;
Fig. 3 is the structural representation of support plate;
Fig. 4 is the support plate side view.
Embodiment
Fig. 1, Fig. 2, wherein 1 is bolt head, and 2 is the body of bolt, and 3 is support plate, and 4 is the support plate groove, 6 is attachment hole.
Fig. 3, Fig. 4, wherein 5 are a plate hole.
Support plate groove 4 that is complementary with bolt head 1 and a plate hole 5 that is complementary with the body of bolt 2 are arranged on support plate 3, the body of bolt 2 passes a plate hole 5, bolt head 1 forms transition fit with support plate groove 4 in groove 4, when swivel nut, because bolt head 1 is subjected to the restriction of support plate groove 4 and can follow nut to rotate together.On the support plate 3 attachment hole 6 can be arranged, be connected or connect by modes such as welding with bolt, the nut of the article that are fixed by other.
