Abstract
A kind of chek bolt, the screw rod comprise head, extending to form from head downwards, is formed at screw thread in screw rod outer rim and locking cap, and described screw thread comprises the first screw thread and the second screw thread, and screw rod is respectively the first screw thread and the second screw thread downwards from head; Described first screw thread is used for thread connection anti-loose cap; Described first screw thread is contrary with the second thread rotary orientation; Described locking cap lower end is provided with locking teeth.The utility model adds a locking cap on existing bolt, and is provided with locking teeth in locking cap lower end surface, because the first screw thread of connection anti-loose cap is contrary with the second thread rotary orientation, so when bolt looseness, its locking cap effectively can stop it; Be subject to the situation compared with high vibration, or when producing resonance under particular frequencies, bolt also cannot loosen because of locking cap.
Description
Technical field
The utility model relates to a kind of chek bolt.
Background technique
In industrial field, there are many places to need to use bolt to carry out fastening locking, but general bolt is all plane with the fitting surface that contacts of packing ring, be subject to the situation compared with high vibration, or when producing resonance under particular frequencies, bolt relatively rotates with packing ring possibly and gets loose, and fastening reliability is high not enough.Require very strict place for some to fastening anti-loosening property, bolt gets loose also may affect normal production run, produces safety problem.
Summary of the invention
The utility model provides a kind of fastening performance reliable chek bolt technical problem to solve exactly.
For solving the problems of the technologies described above, the technical solution of a kind of chek bolt of the utility model is:
The screw rod comprise head, extending to form from head downwards, be formed at screw thread in screw rod outer rim and locking cap, described screw thread comprises the first screw thread and the second screw thread, and screw rod is respectively the first screw thread and the second screw thread downwards from head; Described first screw thread is used for thread connection anti-loose cap; Described first screw thread is contrary with the second thread rotary orientation; Described locking cap lower end is provided with locking teeth.
Described head is provided with interior hexagonal groove, available inner hexagon spanner fixing bolt.
The technique effect that the utility model can reach is: the utility model adds a locking cap on existing bolt, and locking teeth is provided with in locking cap lower end surface, because the first screw thread of connection anti-loose cap is contrary with the second thread rotary orientation, so when bolt looseness, its locking cap effectively can stop it, be subject to the situation compared with high vibration, or when producing resonance under particular frequencies, bolt also cannot loosen because of locking cap.
Accompanying drawing explanation
Below in conjunction with the drawings and specific embodiments, the utility model is described in further detail:
Fig. 1 is the sectional view of a kind of chek bolt of the utility model.
Embodiment
Below in conjunction with accompanying drawing, elaboration detailed is further done to the utility model.
Consult Fig. 1.
Mode of execution one one kinds of chek bolts, the screw rod comprise head, extending to form from head downwards, be formed at screw thread in screw rod outer rim and locking cap, described screw thread comprises the first screw thread 3 and the second screw thread 4, and screw rod is respectively the first screw thread 3 and the second screw thread 4 downwards from head; Described first screw thread 4 is for thread connection anti-loose cap 1; Described first screw thread 3 is contrary with the second screw thread 4 rotation direction; Described locking cap 1 lower end is provided with locking teeth 5.The utility model adds a locking cap 1 on existing bolt, and locking teeth 5 is provided with in locking cap 1 lower end surface, because the first screw thread 3 of connection anti-loose cap 1 is contrary with the second screw thread 4 rotation direction, so when bolt looseness, its locking cap 1 effectively can stop it, be subject to the situation compared with high vibration, or when producing resonance under particular frequencies, bolt also cannot loosen because of locking cap.
Mode of execution two, based on mode of execution one, described head is provided with interior hexagonal groove 2, available inner hexagon spanner fixing bolt.
Working principle of the present utility model and using method as follows:
Bolt screw-in is first wanted in the screw of fixed object by internal angle wrench by the utility model, and the locking teeth 5 being always threaded to locking cap 1 lower end pressed against object end face, at this moment fixedly completes.And when bolt will loosen, locking cap 1 must be driven to leave end face, but pressed against object end face due to locking teeth 5, locking cap 1 cannot normally be rotated; The rotation direction of adding its first screw thread 3 and the second screw thread 4 is contrary, to such an extent as to locking cap 1 only more can be close to end face, and bolt cannot be loosened.
Described locking teeth 5 can be in the outstanding semi-circular teeth of locking cap 1 bottom end, also can be sour jujube type tooth, when bolton is to during with end contact, can only enter and can not move back, if will exit, likely can damage sour jujube type tooth, if so because after repair demolition, need again to change a locking cap 1 again.
Claims (2)
1. a chek bolt, it is characterized in that: the screw rod comprise head, extending to form from head downwards, be formed at screw thread in screw rod outer rim and locking cap, described screw thread comprises the first screw thread and the second screw thread, and screw rod is respectively the first screw thread and the second screw thread downwards from head; Described first screw thread is used for thread connection anti-loose cap; Described first screw thread is contrary with the second thread rotary orientation; Described locking cap lower end is provided with locking teeth.
2. a kind of chek bolt according to claim 1, is characterized in that: described head is provided with interior hexagonal groove, available inner hexagon spanner fixing bolt.
