Abstract
The utility model provides a thread structure which comprises a nut and a bolt with a bolt cap. The thread structure is characterized in that one end, close to the bolt cap, of the nut is provided with a plane. When the bolt penetrates through a pool table leg which needs to be fixed, the nut is screwed into the bolt, the end, which is provided with the plane, of the nut is in contact with planes of each part of a pool table. Due to the fact that the planes of each part of the pool table is in contact with the end, which is provided with the plane, of the nut, the end of the nut and the planes of each part of the pool table are not provided with arcs, the end of the nut and the planes of each part of the pool table can be in full contact; when collision is generated due to the fact that people play pool, a contact area of the end of the nut and the planes of each part of the pool table is large, no gaps are generated, shaking of the pool table is not caused, and therefore normal use of the pool table is ensured.
Description
Technical field
The utility model relates to a kind of fastening piece, particularly a kind of worm structure.
Background technique
Worm structure is to utilize the inclined-plane circular rotating of object and physics and the mathematical principle of frictional force, the by easy stages instrument of fastening implements parts.Worm structure is necessity indispensable in the daily life, is widely used in fields such as electric product, musical instrument, furniture.It is very important to this shows that worm structure plays a part in productive life.Especially in sports apparatus, be widely used; each surface of contact of nut all is arcuate structure in the worm structure on the billiard table; can not with the billiard table close contact; often can bump when playing billiard ball; and then generation vibrations; vibrations can make worm structure produce slit and then absent-mindedness for a long time, cause billiard table to rock, and have affected the normal use of billiard table.
Summary of the invention
According to above technical problem, the utility model provides a kind of worm structure, comprises nut and with the bolt of nut, it is characterized in that described nut is the plane near nut one end.
Described nut is half arcuate structure.
Described nut is cuboid.
Described nut cross section radius is 10mm-17mm.
The beneficial effects of the utility model are: when bolt being passed required fixing billiard table table leg, nut is screwed into bolt, nut be an end and the billiard table each several part plane contact on plane, because billiard table each several part plane and nut plane one end in contact, contact both and all do not have radian, so both can fully contact, when playing billiard ball generation collision, both area of contact are large, can not produce the slit and cause billiard table to rock, and then guarantee the normal use of billiard table.
Description of drawings
Fig. 1 is that the utility model nut is the schematic representation of arcuate structure;
Fig. 2 is that the utility model nut is the schematic representation of rectangular configuration.
Embodiment
According to Fig. 1, shown in Figure 2, the utility model is further specified:
Such as Fig. 1, Fig. 2, bolt 1, nut 2;
Claims (4)
