Abstract
The utility model discloses a screw with a long service life. The screw with the long service life comprises a screw portion with external threads and a nut portion which is connected at the upper end of the screw portion. The upper end face of the nut portion is provided with a driving portion, the driving portion is a rotating ring which is arranged on the upper end face of the nut portion and is of an arched arc shape, two ends of the rotating ring are both fixedly connected with the nut portion, the two ends of the rotating ring are centrally symmetrical relative to the center of a circle of the upper end face of the nut portion, a plurality of sets of bosses are arranged in positions, close to the edge of the upper end face of the nut portion, of the upper end face of the nut portion, and each set of bosses is composed of two rectangular boss units which are centrally symmetrical relative to the center of a circle of the upper end face of the nut portion. Due to the fact that a driving groove is changed and designed to the rotating ring, a user does not need to use any tool, the screw can be rotated directly by hand, and the screw with the long service life is convenient to assemble and disassemble. Due to the fact that the plurality of sets of bosses are further arranged on the nut portion, the screw can be assembled and disassembled through the bosses after the rotating ring is damaged, and the service life of the screw is greatly prolonged.
Description
Technical field
The utility model belongs to technical field of fastening, is specifically related to a kind of long lifetime screw.
Background technique
At present, the screw that generally uses is standard piece, is word screw or a plus screw, constitutes by nut portion and screw part, in the upper-end surface of nut portion driver slot is set, and this screw tightness is good, easy accessibility.But owing to cooperate the driver slot of tightening to be molded over the upper-end surface of nut portion with screw-driver only simplely, after dismounting repeatedly, driver slot cell wall place often is worn, inserting screw-driver a little firmly just can skid off in groove, both scratched hand easily, can't realize tightening and dismantling of screw again, reduce the working life of screw; And existing screw need utilize the dismounting of screw-driver ability, inconvenience.
Summary of the invention
Technical problem to be solved in the utility model is at above-mentioned the deficiencies in the prior art, and a kind of long lifetime screw is provided, and it can carry out dismounting under with instrument landearth-circumstance condition unfavorable, effectively increases the working life of screw simultaneously.
The technological scheme that the utility model adopts is: a kind of long lifetime screw, comprise the nut portion that has externally threaded screw part and be connected the screw part upper end, described nut portion upper-end surface is provided with drive portion, described drive portion is the rotating ring that is arranged on the curved arch of described nut portion upper-end surface, all fixedly connected with described nut portion in the two ends of this rotating ring, and the two ends of rotating ring are about center, the center of circle symmetry of described nut portion upper-end surface, the position that keeps to the side, the upper-end surface of described nut portion is provided with many group boss, and each group boss constitutes by the two centrosymmetric rectangular boss unit, the center of circle with respect to nut portion upper-end surface.
As preferably, the height of described rotating ring is less than 1/3rd of described screw part length.
As preferably, described nut portion upper-end surface is provided with two groups of boss altogether, and these two groups of boss circumferentially evenly distribute along nut portion upper-end surface.
The beneficial effects of the utility model are: because the utility model changes driver slot and is designed to rotating ring, the user need not to use any instrument, directly pulls with hand and gets final product rotary screw, is convenient to dismounting; And, also in nut portion many group boss are set, after damaging, rotating ring also can utilize boss to carry out the dismounting of screw, prolonged the working life of screw greatly.
Description of drawings
Fig. 1 is the utility model structural representation;
Fig. 2 is nut portion plan view.
Among the figure: 1, screw part; 2, nut portion; 3, rotating ring; 4, boss.
Embodiment
Below in conjunction with the accompanying drawings and the specific embodiments the utility model is described in further detail.
As depicted in figs. 1 and 2, a kind of long lifetime screw, comprise the nut portion 2 that has externally threaded screw part 1 and be connected screw part 1 upper end, described nut portion 2 upper-end surfaces are provided with drive portion, described drive portion is the rotating ring 3 that is arranged on the curved arch of described nut portion 2 upper-end surfaces, the height of described rotating ring 3 is less than 1/3rd of described screw part 1 length, all fixedly connected with described nut portion 2 in the two ends of this rotating ring 3, and the two ends of rotating ring 3 are about center, the center of circle symmetry of described nut portion 2 upper-end surfaces, the position that keeps to the side, the upper-end surface of described nut portion 2 is provided with many group boss 4, and each group boss 4 constitutes by the two centrosymmetric rectangular boss unit, the center of circle with respect to nut portion 2 upper-end surfaces.In the present embodiment, be provided with two groups of boss 4 altogether on nut portion 2 upper-end surfaces, these two groups of boss 4 circumferentially evenly distribute along nut portion 2 upper-end surfaces.
Because the utility model changes driver slot and is designed to rotating ring 3, the user need not to use any instrument, directly pulls with hand and gets final product rotary screw, is convenient to dismounting; And, also in nut portion 2 many group boss 4 are set, after damaging, rotating ring 3 also can utilize boss 4 to carry out the dismounting of screw, prolonged the working life of screw greatly.
The above, it only is the utility model preferred embodiment, so can not limit the scope that the utility model is implemented with this, i.e. the equivalence of doing according to the utility model claim and description changes and modifies, and all should still belong in the scope that the utility model patent contains.
