Abstract

The utility model discloses a triangle screw in concave head, it includes a screwed body of rod, the one end of this body of rod forms the head, has the combination groove on the outer terminal surface of head, should combine the groove to be equilateral triangle in, and triangular angle is 60 degrees. The utility model discloses the interior hexagonal screw that will have now changes interior triangle into, and just interior triangle is equilateral triangle, and interior triangle angle is 60 degrees, and limit long ruler is very little to follow the screw size and the change, the possibility that the spanner is worn and torn that has not only significantly reduced, just convenience simple to use, simultaneously, interior triangle still forms the little the higher authority in a bottom three big prismatic table structure for the spanner of its adaptable multiple size, thus make this triangle screw in concave head have fine commonality.

Description

Concave head Triangle ID screw

Technical field

The utility model provides a kind of locking part, and espespecially a kind of head is the screw of concave head Triangle ID.

Background technology

Existing socket screw or screw generally comprise the threaded body of rod of a tool, and one end of the body of rod forms head, head Outer face on there is engagement groove, common engagement groove is yi word pattern, cross, hexangle type or rice font.Wherein, application Most commonly used engagement groove is hexangle type, namely interior mild steel hexagonal socket screw.The interior mild steel hexagonal socket screw is interior hexagonal, but interior six If often dismounting, interior hex socket is easy to be worn angle screw with inner hexagon spanner, causes the screw that dismantle Do not tear open, it should the screw of locking but not tight, do not only result in using upper trouble, also result in that product rejection rate is high to be lacked Fall into.

Utility model content

Therefore, it is the utility model proposes a kind of concave head Triangle ID screw, traditional interior hexagonal is recessed for above-mentioned problem Head is changed to Triangle ID, not only extends the service life of screw and spanner, and product will not also be scrapped because screw is not locked, from And solve the deficiency of prior art.

In order to solve the above-mentioned technical problem, the technical scheme that the utility model is used is, a kind of concave head Triangle ID screw, Including the threaded body of rod of tool, one end of the body of rod forms head, has engagement groove on the outer face of head, and the engagement groove is Equilateral triangle, the angle of Triangle ID is 60 degree.Further, the cell wall of the engagement groove extends to form one to body of rod direction Central recess, the central recess is triangular prism structure.

In order to further coordinate spanner（Or bottle opener）Use, the cell wall of the engagement groove prolongs to body of rod center position Stretch to form a central recess, the central recess is the small three big above terrace with edge structures in bottom.On the bottom of the three terrace with edges structure is small Face is big, then the spanner of various sizes is suitable for, with more preferable versatility.

Further, the side and bottom surface of the three terrace with edges structure（Upper bottom surface or bottom surface）The scope of the acute angle of formation It is 45 degree of -90 degree.

Existing hexagon socket head cap screw is changed to Triangle ID by the utility model, and Triangle ID is equilateral triangle, Triangle ID angle It is 60 degree to spend, and size dimension follows screw size and changes, and not only greatly reduces the possibility that spanner is worn, and use letter Folk prescription is just；Meanwhile, Triangle ID also forms the small three big above terrace with edge structures in a bottom so that it is suitable for pulling for sizes Hand, so that the concave head Triangle ID screw has good versatility.

Specific embodiment

The utility model is further illustrated in conjunction with the drawings and specific embodiments.

Embodiment 1

As a specific embodiment, referring to Fig. 1 and Fig. 2, a kind of concave head Triangle ID screw of the present utility model, including The one threaded body of rod 10 of tool, one end of the body of rod 10 forms head 20, has engagement groove 30, the knot on the outer face of head 20 Conjunction groove 30 is equilateral triangle, and the angle of Triangle ID is 60 degree.Traditional interior hex socket is changed to Triangle ID, is not only extended The service life of screw and spanner, product also will not be scrapped because screw is not locked.In addition, in the present embodiment, engagement groove 30 cell wall extends to form a central recess to body of rod direction, and the central recess is triangular prism structure.

Embodiment 2

In order to further coordinate spanner（Or bottle opener）Use, referring to Fig. 3, Fig. 4 and Fig. 5, the cell wall of engagement groove 30 Extend to form a central recess to the center position of the body of rod, the central recess is the small three big above terrace with edge structures 40 in bottom.Should The bottom of three terrace with edge structures 40 is small big above, then the spanner of various sizes is suitable for, with more preferable versatility.The present embodiment In, the side and bottom surface of three terrace with edge structures 40（Upper bottom surface or bottom surface）The scope of the acute angle ∠ A of formation is 68 degree, preferably , the scope of ∠ A is between 45 degree and 90 degree.

Existing hexagon socket head cap screw is changed to Triangle ID by the utility model, and Triangle ID is equilateral triangle, Triangle ID angle It is 60 degree to spend, and size dimension follows screw size and changes, and not only greatly reduces the possibility that spanner is worn, and use letter Folk prescription is just；Meanwhile, Triangle ID also forms the small three big above terrace with edge structures 40 in a bottom so that it is suitable for pulling for sizes Hand, so that the concave head Triangle ID screw has good versatility.

Although specifically showing and describing the utility model with reference to preferred embodiment, those skilled in the art should This is understood, not departing from the spirit and scope of the present utility model that appended claims are limited, in form and details On the utility model can be made a variety of changes, be protection domain of the present utility model.
