Description
Technical Field
The utility model relates to the field of screws, in particular to a screw with a top embedded inner plum blossom groove body.
Background
The screw is an industrial workpiece with threads on the outer part, is mainly used for fastening two or more products together, and the threads on the outer part can be screwed into an object, so that the screw has the self-tapping effect, and is classified according to varieties, and the screw is generally in the shape of a Chinese character ' yi ', a plum blossom ', an external hexagon, an internal hexagon and the like, wherein the plum blossom is provided with a plum blossom groove body on the surface of the end head of the screw, and can be rotationally assembled and disassembled by using an external plum blossom (cross) screwdriver;
But the screw of current embedded plum blossom cell body has inconvenient problem of using, and traditional plum blossom screw end is even cylinder or cone structure, when the screw needs the self-tapping, uses the screwdriver to use the screw axial rotation's mode, and operates very hard, and because the length of screw also can lead to the screw to appear crooked phenomenon in rotatory in-process, falls into the inside of back, the end can't enter into wooden board moreover, need set up in advance in wooden board's surface with end assorted blind hole, the use convenience is poor.
Disclosure of utility model
The utility model mainly aims to provide a screw with a top embedded inner plum blossom groove body, which can effectively solve the technical problems in the background technology.
In order to achieve the above purpose, the technical scheme adopted by the utility model is as follows:
the utility model provides a screw of plum blossom cell body in top inlays, includes the screw, the outside an organic whole of screw is connected with the external screw thread, the top fixed mounting of screw has the end, plum blossom cell body has been seted up to the upper surface of end, logical groove has been seted up to the surface of end, and the outside an organic whole of end is connected with the toper line.
As a further aspect of the present utility model, the tip is tapered.
As a further proposal of the utility model, the bottom end of the screw is provided with a pointed end, and the external thread extends to the bottom end of the pointed end.
As a further scheme of the utility model, the diameter of the through groove is the same as the maximum diameter of the plum blossom groove body.
As a further aspect of the present utility model, the pitch of the taper thread is smaller than the pitch of the external thread.
The beneficial effects of the utility model are as follows:
Through the arrangement of the through groove, the force application lever is convenient to increase when screwing the screw, the operation is more labor-saving, the labor-saving effect is better when the screw is in self-tapping work, the stability is better, and the phenomenon of screw installation deflection is reduced;
Through setting up the toper line, the end of being possesses the effect of self-tapping to in through the rotatory screw of application of force, the end of being is self-tapping to the object inboard, is convenient for make the end keep under same surface with the installation object, need not to open in advance, and the convenience is higher, and the self-tapping effect of toper line in addition also can effectively increase the stability of screw, reduces the phenomenon of returning.

Detailed Description
The utility model is further described in connection with the following detailed description, in order to make the technical means, the creation characteristics, the achievement of the purpose and the effect of the utility model easy to understand.
As shown in fig. 1-4, a screw with a top embedded inner plum blossom groove body comprises a screw 1, wherein an external thread 2 is integrally connected with the outside of the screw 1, a head 3 is fixedly arranged at the top end of the screw 1, the plum blossom groove body 4 is arranged on the upper surface of the head 3, a through groove 5 is arranged on the outer surface of the head 3, and conical threads 6 are integrally connected with the outside of the head 3.
In the embodiment, the end head 3 is arranged in a conical shape;
the end head 3 is used for limiting the screw 1 and simultaneously plays a role in facilitating the operation of the screw 1 by an external tool.
In the embodiment, the bottom end of the screw 1 is provided with a pointed end, and the external thread 2 extends to the bottom end of the pointed end;
The tip can make things convenient for screw 1 to enter into in the screw more quick, smooth and easy, and self-tapping performance is also stronger simultaneously.
In the embodiment, the diameter of the through groove 5 is the same as the maximum diameter of the plum blossom groove body 4;
Because the diameter of the through groove 5 is the same as that of the plum blossom groove body 4, a screwdriver which can be inserted into the plum blossom groove body 4 can be inserted into the through groove 5, so that the screw 1 can be conveniently and transversely rotated by the screwdriver, and the self-tapping work of the screw 1 is more labor-saving.
In this embodiment, the pitch of the taper 6 is smaller than the pitch of the external thread 2.
It should be noted that, the present utility model is a screw with top embedded inner plum blossom groove body, when in use, an external screwdriver is used to insert into the plum blossom groove body 4, then the screw 1 is rotated, the screw 1 is continuously screwed into the opened screw hole through the external thread 2;
When self-tapping is needed, a screw belt is inserted into the plum blossom groove body 4, the screw 1 is forced to be pressed on the surface of an object, the screw 1 is rotated by a screw driver, the external thread 2 continuously stretches into the object, after the screw 1 is stable, the screw driver can be inserted into the through groove 5, the screw 1 can be driven to rotate by transversely rotating the screw driver, and a force application lever is increased, so that the operation is more labor-saving;
When the screw is screwed into the position of the end head 3, the taper line 6 is screwed into the inner side of the object, so that the end head 3 is conveniently hidden into the inner side of the object, and the anti-falling effect of the screw 1 can be improved.
The foregoing has shown and described the basic principles and main features of the present utility model and the advantages of the present utility model. It will be understood by those skilled in the art that the present utility model is not limited to the embodiments described above, and that the above embodiments and descriptions are merely illustrative of the principles of the present utility model, and various changes and modifications may be made without departing from the spirit and scope of the utility model, which is defined in the appended claims. The scope of the utility model is defined by the appended claims and equivalents thereof.
