Abstract
The utility model provides a potting formula screw belongs to machine part technical field. It includes screwhead and the shank of screw that has the external screw thread, distance on the screwhead be equipped with the tooth on the shank of screw terminal surface far away. The potting formula screw bonding force that can improve the screw with prevent the commentaries on classics ability.
Description
Technical field
This utility model relates to a kind of potting formula screw, belongs to machine components technical field.
Background technology
In the place that needs are spirally connected, in some cases in order to attractive in appearance, screw can not expose, generally use potting formula screw, head of screw is embedded in inside workpiece, and when screw is connected with nut screw connection, needs rotate against, and the bonding dynamics of the potting formula screw used at present is inadequate, easily occur in using loosening, and anti-rotation ability is relatively low.
Utility model content
For drawbacks described above present in prior art, this utility model provides a kind of potting formula screw that can improve screw bonding force and anti-rotation ability.
This utility model is achieved by the following technical solution: a kind of potting formula screw, including head of screw with externally threaded shank of screw, described head of screw is provided with tooth away from described shank of screw end face farther out.
For being prone to the entrance of bonding agent, described tooth includes that chamfered portion, the lower of described chamfered portion are positioned at the end face center of described head of screw.
For improving bond area further, described head of screw and described shank of screw are provided with passage vertically.
Potting formula screw described in the utility model is provided with tooth, and when screw is imbedded workpiece, tooth can increase the contact area of screw and bonding agent, i.e. add bond area, therefore can improve the bonding force of screw and workpiece, arranging of tooth can also increase rotational resistance, improves the anti-rotation ability of screw.

Fig. 3 is that the A of Fig. 2 is to sectional view；
Fig. 4 is the schematic diagram that potting formula screw described in this utility model embodiment is embedded in workpiece；
In figure, 1, head of screw, 2, shank of screw, 3, tooth, 4, workpiece, 5, bonding agent, 6, passage.
Detailed description of the invention
Below by the embodiment of indefiniteness and combine accompanying drawing this utility model is further described:
As shown in Figure 1-Figure 3, this utility model embodiment provides a kind of potting formula screw, including head of screw 1 with externally threaded shank of screw 2, head of screw 1 is provided with tooth 3 away from shank of screw 2 end face farther out.
As Figure 1-Figure 4, potting formula screw described in this utility model embodiment is provided with tooth 3, when screw is imbedded workpiece 4, tooth 3 can increase the contact area of screw and bonding agent 5, i.e. add bond area, therefore can improve the bonding force of screw and workpiece 4, arranging of tooth 3 can also increase rotational resistance, improves the anti-rotation ability of screw.
For being prone to the entrance of bonding agent 5, tooth 3 includes chamfered portion, and the lower of chamfered portion is positioned at the end face center of head of screw 1, beneficially bonding agent 5 and enters between each tooth 3.
For improving bond area further, head of screw 1 and shank of screw 2 being provided with passage 6 vertically, the air between bonding agent 5 and screw can be drained by passage 6, thus improves bond area, increases bonding force.
Above-described embodiment is only used for explanation of the present utility model, and without limiting it, those skilled in the art also can make a change on this basis.
