Abstract
The utility model discloses a socket head cap screw. The socket head cap screw consists of a socket head cap, a screw rod and a screw neck. Six cross sections of a hexagonal blind hole in the socket head cap are arc, and a small segment of screw neck without threads is arranged between the socket head cap and the screw rod; the screw neck is provided with an adjustable cushion, the shape of the socket head cap is round, the diameter of the socket head cap is larger than that of the screw rod, the screw rod is provided with round spiral threads, and each round thread is arranged by a same angle; and the socket head cap screw bears relatively large tightening torque, and has high connection strength and compact structure.
Description
Technical field:
The utility model relates to a kind of screw, is specifically related to a kind of socket head screw.
Background technique:
It is very widely that socket head screw uses at machinery industry, and socket head screw is when screwing or dismantle, on six planes of the Point of Strength of spanner hexagonal blind hole in the termination.But in long-term using process a fatal shortcoming being arranged is exactly hexagonal cunning side to occur easily, because in the plane of the general recessed equipment component of socket head screw, but be not exposed to the clamping point of outside, cause and take out relatively difficulty of damaged screw, people often take a lot of ways, but slightly do not note or removing method improper, cause damage will for machinery itself, also may cause thoroughly scrapping of equipment component when serious, cause larger economic loss, but also waste time and energy.
The model utility content:
For the technical deficiency of existing the said goods, the purpose of this utility model is to provide a kind of socket head screw, and it is comprised of interior hexagon end head, screw rod, spiral shell neck.
The technological scheme that its technical problem that solves the utility model adopts is: six of the hexagonal blind hole cross sections are arc in the screw termination, one trifle is arranged without the spiral shell neck of thread between interior hexagon end head and the screw rod, install on the spiral shell neck and regulate pad, the diameter of interior hexagon end head is greater than screw diameter, screw rod is provided with the thread with round spiral, and each circular thread is the arrangement with angle.
The beneficial effects of the utility model are: bear larger screw-down torque, join strength is high, compact structure.
Description of drawings:
Fig. 1 is the utility model overall structure schematic representation; Fig. 2 is the whole side of the utility model structural representation;
Among the figure, 1, interior hexagon end head 2, screw rod 3, spiral shell neck 4, cross section
Embodiment:
As shown in the figure, a kind of interior hexagonal flush end Cock screw, it is comprised of interior hexagon end head 1, screw rod 2, spiral shell neck 3, cross section 4.Six of the hexagonal blind hole cross sections 4 are arc in the screw termination, one trifle is arranged without the spiral shell neck 3 of thread between interior hexagon end head 1 and the screw rod 2, install on the spiral shell neck 3 and regulate pad, interior hexagon end head 1 profile is the circle shape, the diameter of interior hexagon end head 1 is greater than screw rod 2 diameters, screw rod 2 is provided with the thread with round spiral, and each circular thread is the arrangement with angle, compact overall structure.
