Detailed Description
In order to make the objects, technical solutions and advantages of the present invention more clearly understood, the present invention is further described in detail below with reference to the accompanying drawings and embodiments. It should be understood that the specific embodiments described herein are merely illustrative of the invention and are not intended to limit the invention.
The following detailed description is provided to illustrate specific embodiments of the present invention.
Referring to fig. 1 to 3, an embodiment of the present invention provides a plow-shaped self-tapping screw, including:
the upper end part of the rod body part 1 is detachably connected with an end head part 2;
the upper end part of the rod body part 1 is connected with an integrated butt joint plate 3, a hexagonal buckle groove 4 is formed in the center of the upper end face of the butt joint plate 3, and the diameter of the butt joint plate 3 is larger than that of the rod body part 1;
the center of the lower end part of the end head part 2 is connected with an integrated hexagonal buckle block 6;
the size of the hexagonal buckling block 6 is matched with that of the hexagonal buckling groove 4.
It should be noted that: the self-tapping screw has the function of split assembly, namely the rod body part 1 and the end head part 2 can be disassembled, so that the self-tapping screw can be disassembled pertinently after the groove in the end head part 2 is obviously abraded, and then the self-tapping screw can be replaced to form a complete and undamaged screw, so that the screw can be driven in or taken out again, the undamaged rod body part 1 in the screw can be ensured to be continuously used, and the workability of the screw is improved;
it should also be noted that: a hexagonal buckling groove 4 is formed in an integrated butt joint plate 3 at the end part of the rod body part 1, a hexagonal buckling block 6 is fixed at the lower end of the end head part 2, the hexagonal buckling groove and the hexagonal buckling block can be mutually inserted to realize the fit butt joint of the hexagonal buckling groove and the hexagonal buckling block, the hexagonal buckling block and the hexagonal buckling block are hexagonal, the limiting effect generated by the hexagonal buckling block and the hexagonal buckling block is higher, the compression resistance is higher, and the follow-up situation of damage is not easy to occur;
it should also be noted that: the diameter of the butt plate 3 is larger than that of the body 1, so that the butt plate 3 contacts the surface of the object and plays a role of limitation after the whole screw is driven into other devices, and the head 2 is not subject to the reaction force generated by the object and is not separated from the body 1.
In the embodiment of the present invention, please refer to fig. 2 and 3, the upper end of the butt plate 3 is further provided with a plurality of auxiliary catching grooves 5 distributed in a ring shape with the hexagonal catching groove 4 as a circle center;
the lower end part of the end head part 2 takes the hexagonal buckling block 6 as the circle center, and is also fixed with auxiliary buckling blocks 7 corresponding to the auxiliary buckling grooves 5 in number and position;
when the hexagonal buckling groove 4 in the rod body part 1 is butted with the hexagonal buckling block 6 on the end head part 2, the auxiliary buckling block 7 is also inserted into the auxiliary buckling groove 5.
It should be noted that: when the auxiliary buckling block 7 and the auxiliary buckling groove 5 are mutually inserted, the functional effect of butt joint of the hexagonal buckling block 6 and the hexagonal buckling groove 4 is achieved, namely when the end head part 2 is driven to rotate by a screwdriver, external force can be transmitted to the rod body part 1 by the auxiliary buckling block 7;
it should also be noted that: the plurality of auxiliary buckling blocks 7 can divide the acting force generated by the end head part 2 on the rod body part 1, so that the external force applied to the hexagonal buckling block 6 per se can be smaller, the hexagonal buckling block is not easy to damage, the overall protection effect is higher, the auxiliary buckling blocks 7 are annularly distributed outside the hexagonal buckling block 6, the connection range between the rod body part 1 and the end head part 2 is larger, and the external force transmission effect of the end head part 2 on the rod body part 1 is better;
it should also be noted that: when the auxiliary buckle block 7 is inserted into the auxiliary buckle slot 5, the connection structure between the end part 2 and the rod body part 1 can be increased, so that the connection stability between the end part 2 and the rod body part 1 is higher, and the whole body is more compact.
In the embodiment of the present invention, referring to fig. 3, two grooves 8 are further formed at the edge of the lower end surface of the end head portion 2, and the two grooves 8 are arranged in a mirror image manner with the center of the end head portion 2 as a base point.
It should be noted that: the lower terminal surface of starting groove 8 and seting up in end portion 2 consequently utilizes other structures to peg graft after starting groove 8 is inside, can produce ascending power to end portion 2 to can take out end portion 2 from body of rod portion 1, two play 8 positions in groove are corresponding moreover, and the effort that consequently produces is in same straight line, and the effect can be better.
The above is only the embodiment of the present invention, not limiting the scope of the present invention, all the equivalent structures or equivalent processes of the present invention can be used in other related technical fields, directly or indirectly, or in the same way as the present invention.
