Abstract
The utility model relates to a bolt which comprises a bolt head and a bolt rod. The bolt head and the bolt rod are integrally connected. Grooves are formed on two symmetrical sides of the bolt head. Rotating blocks which can vertically rotate are arranged inside the grooves. When the rotating blocks rotate 90 degrees, the lower surfaces of the rotating blocks are level with the lower surface of the bolt head. Magnets are arranged on the outer end faces of the rotating blocks. The grooves penetrate through the upper surface and the lower surface of the bolt head. The size of each rotating block is the same as the size of each groove. Magnets are arranged on the inner end faces of the rotating blocks. According to the bolt, under a common state, the rotating blocks are arranged in the grooves, after the bolt rod is screwed into a threaded hole, the rotating blocks rotate 90 degrees, due to the fact that the magnets are arranged on the lower surfaces of the rotating blocks, even if a thread of the bolt is abraded because of long-term mechanical vibration, the bolt cannot fly out of the threaded hole easily, the using safety of the bolt is improved, and unnecessary person injury is avoided.
Description
Technical field
The utility model relates to a kind of bolt, and the screw thread that relates in particular to a kind of bolt is because of after long-term mechanical vibration cause wearing and tearing, the bolt of the tapped hole that is difficult for flying out.
Background technique
Bolt is used for being fastenedly connected two with the mechanical parts of through hole by bolt head and screw rod (with an externally threaded cylindrical body) class fastening piece dimerous.If bolt is screwed out, can make again these two mechanical parts separately, be to belong to removably connect so bolt connects.When machinery is moved, unavoidably can produce mechanical vibration, long-term mechanical vibration cause the thread abrasion of bolt, so that the fastening deleterious of bolt, the fly out phenomenon of tapped hole of bolt may occur, and cause unnecessary injury to personnel.
The model utility content
The utility model purpose is screw thread that a kind of bolt is provided in order to overcome the deficiencies in the prior art because of after long-term mechanical vibration cause wearing and tearing, the bolt of the tapped hole that is difficult for flying out.
For achieving the above object, the technical solution adopted in the utility model is: a kind of bolt, comprise bolt head and screw rod, and described bolt head and screw rod connect into an integral body, have groove on two sides of described bolt head symmetry; Be provided with the spin-block that can vertically rotate in the described groove; During described spin-block half-twist, the lower surface of described spin-block is equal with the lower surface of bolt head; The exterior edge face of described spin-block is provided with magnet.
Preferably, upper surface and the lower surface of described groove in-and-out bolt head.
Preferably, the size of described spin-block and groove is big or small identical.
Preferably, the interior edge face of described spin-block is provided with magnet.
Because the utilization of technique scheme, the utility model compared with prior art has following advantages:
Bolt of the present utility model, under the general state, spin-block is positioned at groove, after screw rod screws in tapped hole, the spin-block half-twist, because the lower surface of spin-block is provided with magnet, even the screw thread of bolt because of long-term mechanical vibration cause wearing and tearing after, also be difficult for the tapped hole that flies out, increased the use safety of bolt, avoided unnecessary injury to personnel.
Description of drawings
Below in conjunction with accompanying drawing technical solutions of the utility model are described further:
Accompanying drawing 1 is the stereogram of bolt of the present utility model;
Accompanying drawing 2 is the use state stereogram of bolt of the present utility model;
Wherein: 1, bolt head; 2, screw rod; 3, groove; 4, spin-block; 5, magnet.
Embodiment
The utility model is described in further detail below in conjunction with drawings and the specific embodiments.
Described in the utility model a kind of bolt as shown in Figure 1 comprises bolt head 1 and screw rod 2, and described bolt head 1 and screw rod 2 connect into an integral body, has groove 3 on two sides of described bolt head 1 symmetry; Upper surface and the lower surface of described groove 3 in-and-out bolt heads 1; Be provided with the spin-block 4 that can vertically rotate in the described groove 3; The size of described spin-block 4 is big or small identical with groove 3; During described spin-block 4 half-twist, the lower surface of described spin-block 4 is equal with the lower surface of bolt head 1; The exterior edge face of described spin-block 4 is provided with magnet 5; The internal surface of described spin-block 4 is provided with magnet 5.
Described in the utility model a kind of bolt as shown in Figure 2, under the general state, spin-block 4 is positioned at groove 3, after screw rod 2 screws in tapped hole, spin-block 4 half-twists, because the lower surface of spin-block 4 is provided with magnet 5, even the screw thread of bolt because of long-term mechanical vibration cause wearing and tearing after, also be difficult for the tapped hole that flies out, increased the use safety of bolt, avoided unnecessary injury to personnel.
Below only be concrete exemplary applications of the present utility model, protection domain of the present utility model is not constituted any limitation.All employing equivalents or equivalence are replaced and the technological scheme of formation, all drop within the utility model rights protection scope.
