Abstract
The utility model relates to a kind of self-rotation type screw, comprise nut and stud, it is characterized in that: described stud and nut joint are provided with driven unit, described driven unit comprises the cord making screw rotation, and fixed unit cord is fixed on stud, described cord comprises movable end and fixed end, and the fixed end of described cord is connected with fixed unit, described movable end is wound on stud, and the weight of described nut is greater than the weight of stud.Driven unit is cord, and this ine wound is on stud, when needs by screws tighten to screw time, usually screw will be rotated, now screw will according to the screw thread rotation in screw in screw.
Description
Technical field
The utility model relates to a kind of fastening piece, especially a kind of easy for installation, the simple self-rotation type screw of structure.
Background technique
Existing fastening piece is generally screw-type fastening piece, by arranging screw thread on screw, the screw mouth suitable with this screw thread is set again, by screw-driver by screws tighten in this screw mouth, but the screw arranged like this also exists one always installs comparatively loaded down with trivial details problem, the screw due to different size needs the screw-driver being equipped with dimension, when mounting screw, screw-driver to be equipped with simultaneously, not only carry and bring inconvenience, and also bring larger trouble installing.
Summary of the invention
Problem to be solved in the utility model is to provide a kind of easy for installation, the simple self-rotation type screw of structure.
For solving the problems of the technologies described above, the utility model comprises nut and stud, described stud and nut joint are provided with driven unit, described driven unit comprises the cord making screw rotation, and fixed unit cord is fixed on stud, described cord comprises movable end and fixed end, and the fixed end of described cord is connected with fixed unit, described movable end is wound on stud, and the weight of described nut is greater than the weight of stud.
After have employed said structure, driven unit is cord, and this ine wound is on stud, when needs by screws tighten to screw time, usually screw will be rotated, now screw will according to the screw thread rotation in screw in screw.
As further improvement of the utility model, described fixed unit is the perforation be arranged on stud, and fixed end through this perforation, and ties up in perforation by the fixed end of described cord.
After have employed said structure, fixed unit is by setting of boring a hole, and structure is simple, and it is convenient to implement, and only by the fixed end of cord through perforation, then need be tied up to by rope in this perforation, just serves fixing technique effect.
As further improvement of the utility model, described stud outer wall place is circumferentially with a circle restraining groove along center stud, the width of described restraining groove and the width of cord suitable, described cord can be around in this restraining groove.
After have employed said structure, arranging of restraining groove can make cord be around on this restraining groove, reduces the width that when cord takes up, stud increases, and facilitates the use of screw and the processing of technique.
Accompanying drawing explanation
figure 1 shows that screw cord takes up structural representation;
figure 2 shows that screw cord loose configuration schematic diagram.
Embodiment
As shown in Figure 1, this model utility comprises nut (1) and stud (2), described stud (2) and nut (1) joint are provided with driven unit (3), described driven unit (3) comprises the cord (31) making screw rotation, and cord (31) is fixed on the fixed unit on stud (2), described cord (31) comprises movable end (311) and fixed end (312), the fixed end (312) of described cord (31) is connected with fixed unit (312), described movable end (311) is wound on stud (2), the weight of described nut (1) is greater than the weight of stud (2).Because driven unit (3) is cord, and this cord (31) is wound to (2) on stud, when needs by screws tighten to screw time, usually screw will be rotated, now screw will according to the screw thread rotation in screw in screw.
As shown in Figure 2, described fixed unit is for being arranged at the perforation (32) on stud (2), and fixed end (312) through this perforation (321), and ties up in perforation (32) by the fixed end (312) of described cord (31).Fixed unit (32) is arranged by perforation, and structure is simple, and it is convenient to implement, and only by the fixed end of cord (31) (312) through perforation (32), then need be tied up to by rope in this perforation, just serves fixing technique effect.Described stud (2) outer wall place is circumferentially with a circle restraining groove (4) along center stud, the width of described restraining groove (4) and the width of cord (31) suitable, described cord (31) can be around in this restraining groove (4).Arranging of restraining groove (4) can make cord (31) be around on this restraining groove (4), reduces the width that when cord (31) takes up, stud (2) increases, facilitates the use of screw and the processing of technique.
During use, with clockwise rotatable enter screw, producing screw is counterclockwise example, when in needs screws tighten to screw, by cord wrapped anti-clockwise, the weight due to nut is greater than the weight of stud, the center of gravity of screw is located in nut place, just provide a downward pressure when rotary screw, the steering force produced when rotating according to downward pressure and cord, screw just can be transferred in screw.
Claims (3)
1. a self-rotation type screw, comprise nut and stud, it is characterized in that: described stud and nut joint are provided with driven unit, described driven unit comprises the cord making screw rotation, and fixed unit cord is fixed on stud, described cord comprises movable end and fixed end, and the fixed end of described cord is connected with fixed unit, described movable end is wound on stud, and the weight of described nut is greater than the weight of stud.
2. self-rotation type screw according to claim 1, is characterized in that: described fixed unit is the perforation be arranged on stud, and fixed end through this perforation, and ties up in perforation by the fixed end of described cord.
3. self-rotation type screw according to claim 1, is characterized in that: described stud outer wall place is circumferentially with a circle restraining groove along center stud, the width of described restraining groove and the width of cord suitable, described cord can be around in this restraining groove.
