Abstract
The utility model provides a T-shaped bolt which comprises a bolt head and a screw. The bolt head is arranged at the top end of the screw, a thread is positioned at the lower portion of the screw, an outer edge of the bolt head is an inclined edge, antiskid ribs are arranged at the bottom of the inclined edge, and a groove is arranged at the top of the bolt head. A plurality of antiskid ribs are arranged on the bottom surface of the bolt head and arranged together with the plane of a component to form sealing. Thus, sealing performance is improved, and friction is large due to the fact that the bolt is contacted with the plane of the component in a multiple mode.
Description
Technical field
The utility model relates to the fastening piece association area, particularly a kind of T bolt.
Background technique
Bolt is widely used as conventional fasteners; Traditional T shape bolt is made up of head, screw rod, afterbody, and its head is to be a rectangular plane, and the T bolt of this structure in use; The surface of contact of T bolt and conduit is a smooth surface; Its frictional force is little, and it is firmly not enough when connecting, and comes off easily.It is hypotenuse increasing frictional force with head design that the people is arranged for this reason, but design has only a hypotenuse to contact with parts like this, and sealing is not fine.
The model utility content
To above problem, the utility model increases the anti-skidding muscle of multiple tracks through a kind of T bolt of design in bolt head bottom surface; Thereby can form multiple-sealedly with the parts plane, for reaching this purpose, the utility model provides a kind of T bolt together; Comprise bolt head and screw rod, said bolt head is installed in screw tip, and there is screw thread said screw rod below; Said bolt head outside is a hypotenuse, and anti-skidding muscle is arranged at said hypotenuse bottom, and said bolt head top has groove.
Further improvement as the utility model; Said anti-skidding muscle has the 2-3 road; Thereby can through the anti-skidding muscle of bolt head contact with the parts plane form multiple-sealed because the many more costs of anti-skidding muscle can increase to some extent, so producer can be provided with the anti-skidding muscle in 2-3 road according to sealing needs and friction needs.
As the further improvement of the utility model, said bolt head top groove is cross recess or straight groove, and this special bolt head top groove is cross recess or straight groove, and producer can select as required.
The utility model increases the anti-skidding muscle of multiple tracks through a kind of T bolt of design in bolt head bottom surface, with the parts plane together, can form multiple-sealed, thereby improved sealing, and because bolt has multiple tracks to contact with the parts plane so frictional force is bigger.
Description of drawings
Fig. 1 is the utility model structural representation;
Member among the figure is:
1, bolt head; 1-1, groove; 1-2, hypotenuse; 1-3, anti-skidding muscle; 2, screw rod; 2-1, screw thread.
Embodiment
Below in conjunction with accompanying drawing and embodiment model utility is done detailed explanation:
The utility model increases the anti-skidding muscle of multiple tracks, thereby can form multiple-sealed with the parts plane together through a kind of T bolt of design in bolt head bottom surface.
The utility model provides structural representation a kind of T bolt as shown in Figure 1, comprises bolt head 1 and screw rod 2, and said bolt head 1 is installed in screw rod 2 tops; There is screw thread 2-1 said screw rod 2 belows, and said bolt head 1 outside is hypotenuse 1-2, and anti-skidding muscle 1-3 is arranged at said hypotenuse 1-2 bottom; Said anti-skidding muscle 1-3 has the 2-3 road, thus can through the anti-skidding muscle 1-3 of bolt head contact with the parts plane form multiple-sealed because the many more costs of anti-skidding muscle 1-3 can increase to some extent; So producer can be provided with the anti-skidding muscle 1-3 in 2-3 road according to sealing needs and friction needs; Groove 1-1 is arranged at said bolt head 1 top, and said bolt head 1 top slot 1-1 is cross recess or straight groove, and producer can select as required.
The utility model increases the anti-skidding muscle of multiple tracks through a kind of T bolt of design in bolt head bottom surface, with the parts plane together, can form multiple-sealed, thereby improved sealing, and because bolt has multiple tracks to contact with the parts plane so frictional force is bigger.
The above; It only is the preferred embodiment of the utility model; Be not to be the utility model to be done the restriction of any other form, and, still belong to the utility model scope required for protection according to any modification or equivalent variations that the technical spirit of the utility model is done.
