Abstract
The utility model discloses a combined screw, which relates to the field of screws and comprises a circular top plate and a threaded rod, wherein a rectangular rod is welded at the bottom end of the circular top plate, a threaded rod is fixedly connected with the bottom end of the rectangular rod, a rectangular through groove for inserting the rectangular rod into the threaded rod is formed in the threaded rod, and a connecting block is connected to the outer side wall of the threaded rod in a threaded manner.
Description
Technical Field
The utility model relates to the field of screws, in particular to a combined screw.
Background
The screw refers to a screw, which is a tool for fastening a machine part step by utilizing the physical and mathematical principles of the inclined plane circular rotation and friction force of an object.
The length of the threaded rod part of the screw is fixed at present, and the screw cannot be suitable if the height of the threaded rod part of the screw is not matched with the height of the reserved mounting hole, so that the screw cannot be used and can only be left there after many users buy the screw, and waste is caused.
Disclosure of Invention
The utility model mainly aims to provide a combined screw, a threaded rod can be combined by selecting a proper circular top plate to form the screw, the use frequency of the threaded rod part of the screw is greatly improved, waste can be well reduced compared with the situation that the whole screw is idle in the place, and the problems in the background technology can be effectively solved.
In order to achieve the above purpose, the technical scheme adopted by the utility model is as follows:
the utility model provides a combination formula screw, includes circular roof and threaded rod, the bottom welding of circular roof has rectangular bar and rectangular bar's bottom fixedly connected with screw rod, the rectangle logical groove that is used for its to insert rectangular bar is seted up to the inside of threaded rod, threaded connection has the connecting block on the lateral wall of screw rod.
Further, iron oxide red phenolic antirust paint is sprayed on the surfaces of the round top plate and the threaded rod.
Further, a cross groove is formed in the top end of the circular top plate.
Further, the connecting block is conical.
Compared with the prior art, the utility model has the following beneficial effects: the round top plate is divided into various kinds, the difference is that the length of the rectangular rod below the round top plate is different, the round top plate is used for being provided with different threaded rods, when the round top plate is required to be combined, the rectangular through groove on the threaded rod is inserted on the rectangular rod on the round top plate, after the insertion is completed, the threaded rod just in time penetrates out of the threaded rod at the lowest position, then the connecting block is rotated clockwise, the connecting block is installed on the threaded rod through the screw hole on the connecting block, and accordingly the threaded rod can be propped against the threaded rod from the lower position of the threaded rod through the connecting block, and the threaded rod can be combined into a screw for use, so that the threaded rod can be assembled by selecting a proper round top plate, the use frequency of the round top plate is greatly improved, and waste can be well reduced compared with the whole screw.
Drawings
FIG. 1 is a schematic view showing a specific structure of a combination screw according to the present utility model;
fig. 2 is a schematic view of a combined structure of a combined screw according to the present utility model.
In the figure: 1. a circular top plate; 2. a rectangular bar; 3. a threaded rod; 4. a screw; 5. a connecting block; 6. a cross groove; 7. rectangular through grooves.
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.
1-2, a combination formula screw, including circular roof 1 and threaded rod 3, the bottom welding of circular roof 1 has rectangular rod 2 and the bottom fixedly connected with screw rod 4 of rectangular rod 2, rectangular through groove 7 that is used for its inserting rectangular rod 2 is seted up to the inside of threaded rod 3, threaded connection has connecting block 5 on the lateral wall of screw rod 4.
The surfaces of the round top plate 1 and the threaded rod 3 are sprayed with iron red phenolic antirust paint, the iron red phenolic antirust paint has strong adhesive force and is fast to dry, and the iron red phenolic antirust paint is sprayed on the surfaces of the round top plate 1 and the threaded rod 3 and used for preventing corrosion of screws.
Wherein, cross groove 6 has been seted up on the top of circular roof 1, and cross groove 6 is convenient for the staff through the screw driver dismouting screw.
The connecting block 5 is conical, the shape of the connecting block 5 at the lowest part of the combined screw can be selected according to the requirement, and the connecting block can be conical or cylindrical, but the cross section of the connecting block is smaller than that of the threaded rod 3, so that the normal use of the screw is prevented from being influenced.
The utility model relates to a combined screw, the round top plate 1 of the combined screw is divided into various types, the difference is that the lengths of rectangular rods 2 below the combined screw are different, the combined screw is used for being provided with different threaded rods 3 (more than 1 is provided, the lengths of the threaded rods 3 are matched with the lengths of the rectangular rods 3 in fig. 1), when the combined screw is required, rectangular through grooves 7 on the threaded rods 3 are inserted on the rectangular rods 2 on the round top plate 1, after the insertion is completed, the threaded rods 4 just penetrate out of the bottommost threaded rods 3, then the connecting blocks 5 are rotated clockwise, the connecting blocks 5 are installed on the threaded rods 4 through screw holes on the connecting blocks 5, so that the threaded rods 3 can be combined into the screw for use through the connecting blocks 5, the threaded rods 3 can be selectively used for being assembled with the round top plate 1, the use frequency of the combined screw is greatly improved, waste can be well reduced compared with the situation that the whole screw is free, the whole round top plate 1 is not suitable for the lengths of the rectangular rods 2 on the round top plate 1, the whole body is avoided, the waste of the whole threaded rods 3 is avoided, the cross section 6 is convenient for a worker to conveniently use the cross section of the combined screw can be conveniently, but the cross section of the combined screw can be conveniently required to be the screw with the round top plate 3 is required to be the round top plate or the combined with the round top plate is required to be in a round shape with the shape of a round shape with the round top plate, and the round top plate is required to be assembled to be conveniently and the round with the round cross section can be conveniently used.
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.
