Abstract
The utility model provides an unloosening screw with a separation-resistant washer. The unloosening screw comprises a screw head portion and a screw tail portion, and is characterized in that the lower end of the screw head portion is provided with a square washer, the bottom face of the square washer is wave-shaped, the square washer is directly fixed to the lower end of the screw, so that proper washers are needless to be looked for in assembling, and the washer is firmly fixed to the screw and cannot fall. The unloosening screw is simple in structure, low in cost and good in line pressing performance, the washer cannot be separated from the screw, waste caused by the fact that materials are lost is greatly reduced, labor is saved, the time waste phenomenon is reduced, and the screw is suitable for being used and popularized in a large scale.
Description
Technical field
The utility model relates to a kind of mechanical parts, especially a kind ofly for mechanical connection, does not deviate from screw.
Background technique
At present, on market, most of screws and pad are all individual returning individual separating, so need to first find suitable pad to assemble when rigging screw, and the pad volume is little, very easily fall to or lose, thereby bringing many unnecessary troubles, also causing the waste of material and manpower.
Summary of the invention
The purpose of this utility model be provide for the deficiency that solves above-mentioned technology that a kind of pad can not deviate from do not deviate from screw.
In order to achieve the above object, designed a kind of of the utility model do not deviate from screw, it comprises screw head and screw afterbody, the lower end that it is characterized in that described screw head is provided with square washer, direct pad like this and screw lower end connects together in advance, just need to not go again to find suitable pad when assembling, and pad also firmly be fixed on screw and can dropped.For the ease of line ball, the bottom surface of square washer is undulate, can increase when line ball like this with the area of contact of line and facilitate the fixing of line, the processing of the easy wavy surface of square washer simultaneously.
The utility model obtains, and a kind of not deviate from bolt structure simple, and cost is low, presses good linearity, and the screw that can not deviate from of pad, greatly reduced material and caused waste because of loss, and the waste that also saves manpower and time, be suitable for large range promotion use.
