Abstract
The utility model discloses a transmission screw, it is including the location portion and the transmission portion that connect gradually, and the terminal surface of this transmission portion is equipped with the axial screw, and the cross section appearance profile of this transmission portion is square or hexagon, one end that location portion kept away from transmission portion increases radially that to form the card protruding, the utility model has the advantages of reasonable structure design, ingenious lower surface at the head is equipped with a plurality of pawls, the prong orientation of this pawl with revolving to the unanimity of screw thread effectively promotes positional stability, and the antiskid is effectual, and difficult because of vibrations appearance pine takes off the phenomenon, stability is good, firm in connection, and overall structure is simple, can pass through mould one -time molding, and the cost is cheap relatively, and the large tracts of land of being convenient for is popularized and applied.
Description
Technical field
The utility model relates to screw technical field, is specifically related to a kind of drive screw.
Background technique
Although existing screw can meet the effect connecting securing objects, its function singleness, can not drive other parts to rotate, to play transmission effect; For this reason, can only by adding transmission shaft or other transmission part, and make it be connected with actuator by screw, to realize the object of transmission, this is complex structure not only, also makes troubles to installation procedure, and working effect is low, and too increases cost.
Model utility content
For above-mentioned deficiency, the purpose of this utility model is, provides a kind of smart structural design, rationally, has transmission agency, and be easy to the drive screw of erection.
For achieving the above object, technological scheme provided by the utility model is: a kind of drive screw, it comprises the positioning part and transmission unit that connect successively, the end face of this transmission unit is provided with axial screw, the cross-sectional profile profile of this transmission unit is square or Hexagon, and described positioning part increases formation card convex away from one end radial direction of transmission unit.
Improve as one of the present utility model, the cross-sectional profile profile of described positioning part is circular.
Improve as one of the present utility model, described positioning part and transmission unit are integrated linkage structure.Described positioning part and transmission unit on the same axis, are connected firmly, and transmission stability is good.
Improve as one of the present utility model, outer surface is electroplate with color zinc layers, then does dehydrogenation 6h process, effectively promotes wear resistance and alkali resistant acid fastness.
The beneficial effects of the utility model are: reasonable in design of the present utility model, the ingenious lower surface at head is provided with multiple pawl, the crown of this pawl is towards consistent with the rotation direction of described screw thread, effective lifting position stability, good antiskid effect, not easily there is because of vibrations the phenomenon that gets loose, good stability, be connected firmly; And overall structure is simple, can pass through mould disposal molding, relative inexpensiveness., be convenient to large scale application.
Below in conjunction with accompanying drawing and embodiment, the utility model is further illustrated.
Accompanying drawing explanation
Fig. 1 is main TV structure schematic diagram of the present utility model.
Fig. 2 of the present utility modelly looks up structural representation.
Embodiment
See Fig. 1 and Fig. 2, a kind of drive screw that the present embodiment provides, it comprises the positioning part 1 and transmission unit 2 that connect successively, the end face of this transmission unit 2 is provided with axial screw 21, the cross-sectional profile profile of this transmission unit 2 is preferably Hexagon, assembles more tight, good stability; In other embodiment, the cross-sectional profile profile of this transmission unit 2 can be square, and described positioning part 1 increases formation card convex 11 away from one end radial direction of transmission unit 2.
Concrete, the cross-sectional profile profile of described positioning part 1 is circular, convenient for assembly.Described positioning part 1 and transmission unit 2 are integrated linkage structure.Described positioning part 1 and transmission unit 2 on the same axis, are connected firmly, and transmission stability is good.
For increasing the service life, the outer surface electricity of the utility model drive screw is also coated with color zinc layers, then does dehydrogenation 6h process, effectively promotes wear resistance and alkali resistant acid fastness.
To be used in sports shoes locking device for shoelace, during assembling, the gear assembled mutually with the utility model is provided with the hexagon ring suitable with described transmission unit 2, then makes transmission unit 2 insert this hexagon ring, needs the workpiece rotated to be tightened on the axial screw 21 of transmission unit 2.When gear transmission, the workpiece that can correspondingly need rotate rotates, and finally reaches the object of transmission, and assembling is simple, and easy to use, working stability is high.
The announcement of book and instruction according to the above description, the utility model those skilled in the art can also change above-mentioned mode of execution and revise.Therefore, the utility model is not limited to embodiment disclosed and described above, also should fall in the protection domain of claim of the present utility model modifications and changes more of the present utility model.In addition, although employ some specific terms in this specification, these terms just for convenience of description, do not form any restriction to the utility model.As described in the utility model above-described embodiment, adopt structure same or similar with it and other screw obtained all in the utility model protection domain.
