Abstract
The utility model discloses a bolt capable of being easily clamped and dismantled, which comprises a head part (1) and a screw (2), wherein the screw (2) is provided with threads. The bolt is characterized in that the head part (1) is provided with a through hole (11) which is vertical to an axial direction. The head part of the bolt capable of being easily clamped and dismantled is provided with the through hole which is vertical to the axial direction, when the bolt is clamped or dismantled, dedicated tools are not needed, only one stick is needed, and the stick is inserted into the through hole to be rotated. The bolt is simple in operation, and the time can be saved.
Description
Technical field
The utility model belongs to fastener areas, is specifically related to a kind of bolt.
Background technique
Bolt is a kind of adapted nut or the cylindrical threaded fastening piece that is connected with the body screw-thread fit, is used for making two above parts to be fixed together.The bolt of prior art comprises head and screw rod, and wherein bolt head mostly is hexagon head, square head or big homalocephalus cross etc. greatly.The bolt of prior art is tightly torn open needs special instrument.
Therefore, need a kind of new bolt to address the above problem.
The model utility content
The model utility purpose: the utility model is tightly torn the deficiency that needs specialist tools open at bolt in the prior art, and a kind of bolt of easily tightly tearing open is provided.
Technological scheme: for solving the problems of the technologies described above, the bolt of easily tightly tearing open of the present utility model adopts following technological scheme:
A kind of bolt of easily tightly tearing open comprises head and screw rod, and described screw rod is provided with screw thread, and described head is cylindrical, and described columniform arranged outside has arc convex vertically, and described arc convex is evenly distributed in the described columniform outside.
Further, the cross section of described through hole is circular.
Further, described through hole passes the axis of described screw rod.
Further, described head is hexagon head.
Further, described head is provided with five jiaos of endoporus vertically.
Further, described screw rod is provided with guide portion away from an end of described head.
Further, described guide portion is cylindrical, and the diameter of described guide portion is less than the diameter of described screw rod.
Further, described guide portion is frustoconic shape.
Further, the length of described guide portion is the 1/5-1/4 of described spiro rod length.
Further, the diameter of described through hole is 5mm-20mm.
Beneficial effect: the head of easily tightly tearing bolt open of the present utility model is provided with through hole perpendicular to axial direction, when bolt being stepped up or dismantle, need not proprietary instrument, only needs a rod, is inserted in the through hole, and rotation gets final product, and is simple to operate, saves time.
Description of drawings
Fig. 1 easily tightly tears the plan view of bolt open for the utility model;
Fig. 2 easily tightly tears the plan view of bolt open for the utility model.
Embodiment
Below in conjunction with the drawings and specific embodiments, further illustrate the utility model, should understand these embodiments only is used for explanation the utility model and is not used in restriction scope of the present utility model, after having read the utility model, those skilled in the art all fall within the application's claims institute restricted portion to the modification of the various equivalent form of values of the present utility model.
See also illustrated in figures 1 and 2ly, a kind of bolt of easily tightly tearing open of the present utility model comprises head 1 and screw rod 2, and screw rod 2 is provided with screw thread, and head 1 is provided with through hole perpendicular to axial direction 11.Wherein, the cross section of through hole 11 is circular.The diameter of through hole 11 is 5mm-20mm.Through hole 11 passes the axis of screw rod 2.Stressed more even, not fragile.Head 1 is that hexagon head and head 1 are provided with five jiaos of endoporus vertically.Can there be multiple mode fastening and tightly tear bolt open, conveniently tightly tears open.Screw rod 2 is provided with guide portion 3 away from an end of head 1.Make things convenient for screw rod to insert tapped hole.Guide portion 3 is cylindrical, and the diameter of guide portion 3 is less than the diameter of screw rod 2.Guide portion 3 also can be frustoconic shape.The length of guide portion 3 is the 1/5-1/4 of screw rod 2 length.
The head of easily tightly tearing bolt open of the present utility model is provided with through hole perpendicular to axial direction, when bolt being stepped up or dismantle, need not proprietary instrument, only needs a rod, is inserted in the through hole, and rotation gets final product, and is simple to operate, saves time.
